In the conventional component supplying apparatus, it takes time to deliver the axial component to the component inserting apparatus, and therefore, it is required to deliver the axial component from the component supplying apparatus to the component inserting apparatus more efficiently. In contrast, the component supply device is considered to have a structure including: the component insertion device includes a feeding member that feeds an axial component to a supply position where the axial component is delivered to the component insertion device, and a moving mechanism that reciprocates the feeding member in a front-rear direction along a component feeding direction.

Detailed Description

A first aspect of the present invention provides a component supply device, including: a feeding unit that feeds the axial member to the supply position; and a moving mechanism that reciprocates the feeding unit in the front-rear direction along the component feeding direction, the feeding unit including: a pair of feeding members extending in the component feeding direction and provided on both sides of the axial component body to feed the axial component; a pair of holding members that hold the pair of feeding members rotatably by a rotating shaft; a connecting member for connecting the pair of holding members; and a connecting member disposed above the axial member to be fed, the connecting member being detachably attached with the pair of holding members and being connected to the moving mechanism.

According to such a configuration, since the pair of holding members can be fixed by the coupling member, the holding members can be integrated. This can prevent the pair of holding members from being fixed to the connecting member while being displaced from each other. Therefore, the reproducibility of the mounting position of the holding member can be improved, and the pair of holding members can be easily attached to and detached from the connecting member. In addition, the feeding member held by the pair of holding members can be prevented from contacting with other members.

A second aspect of the present invention provides the component supply apparatus as defined in the first aspect, wherein the pair of holding members respectively have fixing portions that extend in the component feeding direction and are fixed to the coupling member, and the coupling member has a coupling portion that extends in the component feeding direction and is coupled to the pair of fixing portions.

According to such a configuration, the fixing portion and the coupling portion extend in the component feeding direction, and the pair of holding members that hold the pair of feeding members extending in the component feeding direction can be coupled more reliably by the coupling member.

A third aspect of the present invention provides the component supply apparatus as described in the first or second aspect, wherein the pair of holding members are respectively linked at a plurality of locations by linking members.

With this configuration, the pair of holding members can be prevented from being coupled by the coupling member in a state of being displaced from each other.

A fourth aspect of the present invention provides the component supply apparatus according to any one of the first to third aspects, wherein the coupling member and the connecting member have positioning portions that are positioned with respect to each other.

According to this configuration, the pair of holding members can be easily attached to the connecting member by positioning the connecting member and the connecting member without positioning the pair of holding members with respect to the connecting member by the positioning portions of the connecting member and the connecting member. Therefore, the workability of assembling the feeding unit can be improved.

A fifth aspect of the present invention provides the component supply apparatus as defined in the fourth aspect, wherein the connecting member has a front side surface extending in the up-down direction, the pair of holding members each have a positioning surface extending in the up-down direction and abutting against the front side surface of the connecting member in the front-back direction, the positioning portion of the connecting member has a through hole penetrating in the up-down direction, the through hole being fitted with a positioning pin for positioning the connecting member and the connecting member with each other, the positioning portion of the connecting member has a through hole penetrating in the up-down direction, the through hole being configured to restrict movement in a width direction orthogonal to the front-back direction by insertion of the positioning pin, and a length in the front-back direction in the through hole of the connecting member is formed longer than a length in the width.

According to such a configuration, the holding member can be positioned in the width direction with respect to the connecting member by inserting the positioning pin into the through holes of the connecting member and the connecting member. Further, the positioning surface of the holding member is brought into contact with the front side surface of the connecting member, whereby the holding member can be positioned in the front-rear direction with respect to the connecting member. Further, since the length of the through hole of the connecting member in the front-rear direction is formed longer than the length of the through hole in the width direction, the holding member can be moved in the front-rear direction in a state where the positioning pin is inserted into the through holes of the connecting member and the connecting member, and the holding member can be positioned with respect to the connecting member more easily.

A sixth aspect of the present invention provides the component supply device according to any one of the first to fifth aspects, further comprising a return prevention unit that prevents the lead wire from moving backward as the feeding unit moves backward in a direction opposite to a component feeding direction, the return prevention unit including: a pair of return prevention rods extending in the vertical direction on both sides of the axial member body, and having lower ends disposed below the lead wires; a pair of lever holding members detachably fixed to the main body portion of the component supply device, and holding the pair of return prevention levers rotatably by a rotating shaft; and a rod coupling member that couples the pair of rod holding members.

According to this configuration, since the pair of lever holding members can be fixed by the lever connecting member, the lever holding members can be integrated. This makes it possible to prevent the pair of rod holding members from being fixed to the main body of the component supply device so as to be displaced from each other. Therefore, the reproducibility of the mounting position of the lever holding member can be improved, and the pair of lever holding members can be easily attached to and detached from the main body portion of the component supply device. In addition, the return prevention lever held by the pair of lever holding members can be prevented from contacting with other members.

A seventh aspect of the present invention provides the component supply apparatus as defined in the sixth aspect, wherein the pair of lever holding members each have a recess that restricts movement of the lever coupling member relative to the lever holding member in the front-rear direction, and the recess is fitted with the lever coupling member.

With this configuration, the pair of lever holding members can be prevented from being coupled by the lever coupling member in a state of being offset from each other.

An eighth aspect of the present invention provides the component supply apparatus as defined in the sixth or seventh aspect, wherein the pair of lever holding members are positioned relative to each other with respect to the main body portion of the component supply apparatus.

With this configuration, the pair of lever holding members can be prevented from being fixed to the main body of the component supply device in a displaced manner. In addition, since the number of fixing portions of the pair of rod holding members to the main body portion of the component supply device can be reduced, workability in attaching and detaching the pair of rod holding members can be improved.

Hereinafter, an exemplary embodiment of a component supply device according to the present invention will be described with reference to the drawings. The present invention is not limited to the specific configurations of the following embodiments, and the present invention includes configurations based on the same technical ideas.

(embodiment mode)

First, the structure of the component mounting apparatus 1 will be described with reference to fig. 1 to 3. Fig. 1 is a plan view showing the structure of a component mounting apparatus 1. Fig. 2 is a schematic explanatory view of the component coupling body C inserted into the component supply device 5. Fig. 3 is a partial sectional view of the component mounting apparatus 1.

In fig. 1, a substrate transfer mechanism 2 is provided at the center of a base 1 a. The substrate transport mechanism 2 transports the substrate 3 carried in from the upstream in the X direction, and positions and holds the substrate at a mounting operation position of a mounting head 10 described below. The substrate transfer mechanism 2 carries out the substrate 3, on which the component mounting operation has been completed, downstream. The substrate transfer mechanism 2 is provided with component supply units 4 on both sides thereof.

Here, the X direction and the Y direction are two axial directions orthogonal to each other in the horizontal plane. The X direction (left-right direction in fig. 1) represents a substrate conveying direction, and the Y direction represents a direction (component feeding direction) from the outside of the component supply unit 4 toward the substrate conveying mechanism 2. That is, the-Y direction is the upstream side (rear), and the + Y direction indicates the downstream side (front). The Z direction is a direction orthogonal to the X direction and the Y direction, and is a vertical direction when the component mounter 1 is installed on a horizontal plane.

A plurality of component supply devices 5 arranged in parallel in the X direction are mounted on the component supply unit 4. The component supply device 5 is a component feeder that pitch-feeds a component assembly C, which is connected to and holds an axial component D (described later), in a direction (Y direction) from the outside of the component supply portion 4 toward the substrate conveyance mechanism 2, and supplies the axial component D to a supply position 5 a. Here, the feeding position 5a indicates a position where the axial component D is fed in the component feeding direction.

Here, the member coupling body C that couples and holds the axial member D and the axial member D will be described with reference to fig. 2. The axial member D includes a member body B and right and left lead wires L extending outward from both ends of the member body B. In the member coupling body C, the plurality of axial members D are arranged at a predetermined pitch Sp, and the ends of the left and right leads L are held by the tape T, respectively, to thereby couple the plurality of axial members D.

In fig. 1, a Y-axis beam 8 having a linear drive mechanism is provided along the Y direction at one end in the X direction on the upper surface of a base 1 a. Two X-axis beams 9 similarly provided with a linear drive mechanism are coupled to the Y-axis beam 8 so as to be movable in the Y direction. The mounting head 10 is mounted on each X-axis beam 9 so as to be movable in the X direction. The mounting head 10 is provided with a plurality of component holding units 11 (three in this case). The Y-axis beam 8 and the X-axis beam 9 constitute a head moving mechanism 12 that moves the mounting head 10 in the horizontal direction (X direction, Y direction).

In fig. 3, the component supply device 5 is mounted on the base 1a in a state where the feeder-side connection portion 5b provided in the component supply device 5 is connected to the device-side connection portion 1b provided in the base 1 a. By connecting the feeder-side connection portion 5b and the apparatus-side connection portion 1b, the component supply apparatus 5 is electrically connected to the component mounting apparatus 1, and air (compressed air) is supplied to the component supply apparatus 5. A component holding portion 11a for holding the lead L of the axial component D subjected to the lead folding process supplied from the component supplying device 5 by sandwiching the lead L is attached to the lower end of each component holding unit 11.

In the component mounting operation, the mounting head 10 is moved upward of the component feeder 5 by the head moving mechanism 12, and the axial component D subjected to the lead wire bending process and supplied to the supply position 5a of the component feeder 5 is held and picked up by the component holding portion 11a (arrow a); the mounting head 10 holding the axial member D is moved by the head moving mechanism 12 to above the substrate 3 held at the mounting work position of the substrate transport mechanism 2, and the axial member D is mounted by inserting the lead L into the through hole 3a formed in the substrate 3 (arrow b).

In fig. 1, a component recognition camera 13 is provided between the component supply unit 4 and the substrate conveyance mechanism 2. When the mounting head 10, which has taken out the axial component D from the component supply unit 4, moves above the component recognition camera 13, the component recognition camera 13 picks up and recognizes the axial component D held by the mounting head 10. Substrate recognition cameras 14 are mounted on the coupling plate 10a on which the mounting heads 10 are mounted, and the substrate recognition cameras 14 are located on the lower surface side of the X-axis beam 9 and move integrally with the mounting heads 10, respectively.

The mounting head 10 moves, and the substrate recognition camera 14 moves above the substrate 3 positioned on the substrate transfer mechanism 2, and picks up an image of a substrate mark (not shown) provided on the substrate 3 to recognize the position of the substrate 3. The substrate recognition camera 14 images the through-hole 3a formed in the substrate 3 to recognize the position of the through-hole 3 a. In the component mounting operation of the axial component D on the substrate 3 by the mounting head 10, the mounting position is corrected by adding the recognition result of the axial component D by the component recognition camera 13 to the recognition result of the substrate 3 and the through hole 3a by the substrate recognition camera 14.

Next, the structure of the component supply device 5 will be described with reference to fig. 4. Fig. 4 is a diagram illustrating the structure of the component supply device 5. In the present embodiment, the component supply device 5 includes a main body portion 5c, a feeder-side connecting portion 5b, and a reel holding portion 5 d. The feeder-side connection portion 5b is provided on the lower surface of the main body portion 5 c. The reel holding portion 5d is provided on the upstream side (left side in fig. 4) of the main body portion 5c in the component feeding direction. A reel 21 is placed on the reel holding portion 5d, and the reel 21 is wound around the component connecting body C inserted from a component insertion opening 5e provided on the upstream side of the main body portion 5C.

A pair of left and right conveying paths 5g are provided in the main body 5C, and the pair of left and right conveying paths 5g guide the component connecting body C substantially horizontally from a component insertion port 5e opened on the upstream side to a discharge port 5f opened on the downstream side (right side in fig. 4) in the component feeding direction. The component connection body C is fed to the downstream side at a pitch in a state where the left and right tapes T constituting the component connection body C are placed on the left and right conveyance paths 5 g. A supply position 5a is provided in the middle of the conveyance path 5 g. That is, the conveying path 5g guides the component connecting body C from the component insertion port 5e on the upstream side in the component feeding direction to the supply position 5a on the downstream side.

In fig. 4, the feeding unit 22, the return prevention unit 42 (fig. 8), the lead wire bending mechanism 23, the component detection unit 46, and the moving mechanism 34 are provided inside the main body portion 5 c. The feeding unit 22 is a unit that feeds the axial member D to the supply position 5 a. In the present embodiment, the feeding unit 22 pitch-feeds the component connected body C to the downstream side along the conveyance path 5 g. The return prevention unit 42 is a unit that prevents the lead wire L from moving backward as the feeding unit 22 moves backward in the direction opposite to the component feeding direction. The component detecting section 46 (a lead detecting lever 47 described later) detects the presence or absence of the lead L of the axial component D at the supply position 5 a. The lead wire bending mechanism 23 is provided on the downstream side of the feeding unit 22. The lead bending mechanism 23 cuts the left and right leads L of the axial member D fed at a predetermined pitch at a predetermined position to be cut off from the tape T, performs a lead bending process of bending the leads L remaining in the member body B downward, and supplies the leads to the supply position 5 a. The feed unit 22, the return prevention unit 42, the component detection unit 46, and the lead wire bending mechanism 23 will be described in detail later.

The moving mechanism 34 is a mechanism that reciprocates the feeding unit 22 in the front-rear direction (Y direction) along the component feeding direction. In the present embodiment, the moving mechanism 34 is an air cylinder. The air cylinder has a cylinder rod (not shown) coupled to the feeding unit 22 (a connecting member 33c described later). The cylinder moves the cylinder rod in and out, thereby reciprocating the rotating shaft 32 in the component feeding direction via the connecting member 33 c.

The tape T after the axial member D is cut off is discharged from the discharge port 5 f. A pair of upper and lower tape discharge guides 24 are provided downstream of the discharge port 5 f. The tape T discharged from the discharge port 5f is discharged downward along the pair of tape discharge guides 24. An operation-display panel 25 is provided on the upper surface of the upstream side of the main body portion 5 c. The operation-display panel 25 is provided with operation buttons for the operator to perform predetermined operation inputs, and display means such as a seven-stroke nixie tube for displaying predetermined contents.

A socket 27 and an air supply port 28 are provided on the side surface on the downstream side of the feeder-side connection portion 5 b. The feeder control portion 26 is electrically connected to the lead bending mechanism 23, the operation-display panel 25, the jack 27, and the moving mechanism 34. The feeder control portion 26 is electrically connected to the apparatus-side connecting portion 1b via the jack 27. Air is supplied to the air supply port 28 through the apparatus-side connecting portion 1 b. The air supplied to the air supply port 28 is supplied to the lead wire bending mechanism 23 and the moving mechanism 34 via the tube 29 provided inside the main body portion 5 c.

Next, the structure of the feeding unit 22 will be described with reference to fig. 5 to 7. Fig. 5 is a perspective view showing a structure in the vicinity of the feeding unit 22. Fig. 6 is a perspective view showing the structure of the feeding unit 22. Fig. 7 is an exploded perspective view of the feeding unit 22.

As shown in fig. 6 and 7, in the present embodiment, the feeding unit 22 includes a pair of left and right feeding members 31, a rotating shaft 32, a pair of left and right holding members 33a, a coupling member 33b, a coupling member 33c, and a spacer 35. The pair of feeding members 31 are provided on both left and right sides of the axial component body B to feed the axial component D. The pair of holding members 33a is a member that holds the pair of feeding members 31 rotatably by the rotating shaft 32. The rotary shaft 32 has a rotary shaft extending in the X direction (a direction orthogonal to the component feeding direction in a horizontal plane). The coupling member 33b is a member that couples the pair of holding members 33 a. The connecting member 33c is a member to which the pair of holding members 33a are detachably attached and which is connected to the moving mechanism 34.

Specifically, the pair of feeding members 31 are members that sequentially feed the respective axial components D of the component coupling body C to the supply position 5a by reciprocating in the component feeding direction. In the present embodiment, the pair of feeding members 31 extend in a flat plate shape in the component feeding direction. The pair of feeding members 31 are coupled to the spacers 35 so as to be positioned between the left and right conveyance paths 5 g. The pair of feeding members 31 has a plurality of downwardly projecting convex feeding claws 36 formed in line in the component feeding direction.

The pair of feeding members 31 are biased in a direction of rotating the downstream side downward by an elastic body 70 such as a spring, and engage with the lead L of the component connecting body C from above. The downward rotation of the pair of feeding members 31 is restricted by the rotation restricting pin 71.

The pair of holding members 33a are provided on both right and left outer sides of the pair of feeding members 31. The pair of holding members 33a are coupled at a plurality of positions by coupling members 33b, for example, with screws or the like.

The fixing portion 33aa extends in a horizontal flat plate shape. Specifically, the fixing portion 33aa extends in the component feeding direction and in the direction in which the pair of holding members 33a face each other. The fixing portion 33aa is provided with a plurality of screw holes 60a and 60 b. The screw hole 60a is provided for coupling the coupling member 33b and the fixing portion 33 aa. The screw hole 60b is provided for coupling the connecting member 33c and the fixing portion 33 aa. The screw holes 60a and 60b are arranged in line in the component feeding direction. The front protrusion 33ab rotatably holds the pair of feeding members 31 by the rotating shaft 32. The rotation restricting pin 71 extends in the direction in which the pair of front protrusions 33ab face each other, among the pair of front protrusions 33 ab. The pair of front protrusions 33ab (holding members 33a) each have: and a positioning surface S1 extending in the vertical direction and abutting against the connecting member 33c in the front-rear direction.

Limiting holes 33d are formed in the left and right end portions of the connecting member 33c in the component feeding direction so as to penetrate the connecting member 33 c. The restricting pin 41a is inserted into the restricting hole 33d from above. The regulating pin 41a is fixed to the main body 5c of the component supply device 5. When the connecting member 33c reciprocates in the component feeding direction, the restricting pin 41a abuts against the downstream-side inner wall and the upstream-side inner wall of the restricting hole 33d, and the connecting member 33c is stopped at the upstream-side and downstream-side stop positions. The distance between the upstream stop position and the downstream stop position is set to be substantially the same as the pitch Sp of the leads L of the member coupling body C.

The connecting member 33c has front side surfaces S2 extending in the vertical direction at both left and right ends. The front side surface S2 abuts on the positioning surface S1 in the front-rear direction.

The positioning portion 62b of the connecting member 33c is a through hole that penetrates in the vertical direction and regulates movement in the width direction (direction orthogonal to the front-rear direction) by insertion of the positioning pin 63. The positioning portion 62b (through hole) of the connecting member 33c is formed to have a length in the front-rear direction longer than that in the width direction.

Next, the structure of the return prevention means 42 will be described with reference to fig. 8 and 9. Fig. 8 is a perspective view showing the structure of the return prevention unit 42. Fig. 9 is an exploded perspective view showing the structure of the return prevention unit 42.

As shown in fig. 8 and 9, the return prevention unit 42 includes a pair of left and right return prevention levers 42a, a pair of left and right lever holding members 44, and a lever coupling member 45. The return prevention unit 42 is provided in parallel with the feeding member 31 in a direction orthogonal to the component feeding direction (fig. 5). The pair of return prevention levers 42a are levers that prevent the lead wire L from returning rearward. The pair of lever holding members 44 are members that hold the pair of return prevention levers 42a rotatably by the rotating shaft 43. The lever coupling member 45 is a member that couples the pair of lever holding members 44.

The pair of return prevention levers 42a are coupled to the upper plate 42B so as to be positioned between the pair of feeding members 31 and the component body B of the axial component D coupled as the component coupling body C. The pair of return prevention rods 42a extend in the vertical direction on both sides of the axial member body B, and the lower end portions 42aa are disposed below the lead L (fig. 19B). Two return prevention claws 42c are formed at the lower portions of the pair of return prevention levers 42a, respectively. A substantially vertical surface S3 is formed on the downstream side of the return prevention claw 42c, and an inclined surface S4 inclined so as to become higher toward the upstream side is formed on the upstream side of the return prevention claw 42 c. The two return prevention claws 42C are formed at positions overlapping the feed claw 36 of the feed member 31 at the same interval as the pitch Sp of the leads L of the component coupling body C. In the present embodiment, the two return prevention claws 42c are provided at positions on the upstream side of the supply position 5 a.

The upper plate 42b is connected to a pair of lever holding members 44 via a rotating shaft 43. The pair of return prevention levers 42a are biased in a direction to rotate the downstream side downward by an elastic body 72 such as a spring. The upper plate 42b is provided with a restricting portion 42e, and the restricting portion 42e abuts against the upper surface of the conveyance path cover 30 to restrict the pair of return prevention levers 42a from rotating downward.

When the component connecting body C is fed to the downstream side pitch, the lead L moving to the downstream side abuts against the inclined surface S4 of the return prevention claw 42C and the pair of return prevention levers 42a are rotated upward, so that the pair of return prevention levers 42a do not interfere with the movement of the component connecting body C. On the other hand, when the component coupling body C moves upstream (when it is returned) following the feeding member 31 moving upstream, the pair of return prevention levers stop the movement of the component coupling body C by making the downstream substantially vertical surface S3 of the return prevention claw 42C substantially vertically contact the lead L. That is, the pair of return prevention levers 42a constitute a retreat prevention mechanism that prevents the member connecting body C from moving to the downstream side and prevents the member connecting body C from moving to the upstream side. By disposing the return prevention claw 42c at a position overlapping the feeding member 31, the length of the component feeding device 5 in the component feeding direction can be reduced.

The pair of lever holding members 44 hold the rotating shaft 43 and are detachably fixed to the main body portion 5c (fig. 5) of the component supply device 5. A pair of rod holding members 44 extend in the component feeding direction, respectively. In the present embodiment, each of the pair of lever holding members 44 has a recess 44a to be fitted to the lever coupling member 45. The recess 44a restricts the forward and backward movement of the lever coupling member 45 with respect to the lever holding member 44. The recess 44a is provided with a mounting hole 44aa penetrating in the vertical direction for mounting the rod coupling member 45.

The pair of lever holding members 44 are mutually positioned with respect to the main body portion 5c of the component supply device 5, respectively. In the present embodiment, the pair of lever holding members 44 have positioning holes 44b that penetrate in the vertical direction. The positioning hole 44b is inserted with a positioning pin (not shown) provided in the body portion 5 c. The pair of lever holding members 44 have attachment holes 44c penetrating in the vertical direction for attaching to the body portion 5 c. The pair of lever holding members 44 have holding holes 44d that open in a direction orthogonal to the component feeding direction. The pair of lever holding members 44 hold the pair of return preventing levers 42a by inserting the rotating shaft 43 into the holding hole 44 d.

The lever coupling member 45 extends in a direction orthogonal to the component feeding direction, and is bridged over the recessed portions 44a of the pair of lever holding members 44. The rod coupling member 45 has mounting holes 45a formed at both left and right ends thereof and penetrating in the vertical direction. The rod coupling member 45 is coupled to the pair of rod holding members 44 by fastening the mounting hole 45a and the mounting hole 44aa with a screw or the like, for example.

Next, the structure of the component detection unit 46 will be described with reference to fig. 10 and 11. Fig. 10 is a perspective view showing a structure in the vicinity of the component detection unit 46 in fig. 5. Fig. 11 is an exploded perspective view of the component detection unit 46.

The component detection unit 46 includes a lead detection lever 47, a lever support portion 48, and a sensor 49. The lead wire detection lever 47 is a lever supported by the lead wire L at the supply position 5 a. The lever support portion 48 is a member that rotatably supports the lead wire detection lever 47. The sensor 49 detects the rotation of the lead detection lever 47. The sensor 49 includes a sensor main body 49a and a sensor support portion 49b that supports the sensor main body 49 a. The sensor support portion 49b is attached to the main body portion 5c of the component supply device 5. The lever support portion 48 is attached to the sensor support portion 49 b.

The lead wire detecting lever 47 is provided outside the feeding member 31 in a direction orthogonal to the component feeding direction. The lead wire detection lever 47 includes a lead wire contact portion 47a whose lower surface is supported by the lead wire L, and a projecting portion 47b (fig. 19d) projecting downward at a position on the upstream side of the lead wire contact portion 47 a. The lead wire contact portion 47a is disposed at the supply position 5 a. The protrusion 47b is disposed forward of the return prevention lever 42 a. A substantially vertical surface S5 is formed on the downstream side of the protruding portion 47b, and an inclined surface S6 inclined so as to become higher toward the upstream side is formed on the upstream side of the protruding portion 47 b.

The lead wire detection lever 47 is rotatably supported by the lever support portion 48 via a rotation shaft 47 c. A sensor dog (sensor dog)47d is attached to the lead wire detection lever 47, and the lead wire detection lever 47 and the sensor dog 47d integrally rotate around a rotation shaft 47 c. When the lead wire L is not present in the lead wire contact portion 47a, the sensor stopper 47d rotates downward together with the lead wire detection lever 47 to shield the sensor 49 from light.

The lead wire detection lever 47 is provided with a lever rotation restricting pin 47e that restricts rotation of the lead wire detection lever 47. The lever rotation limiting pin 47e limits the sensor stopper 47d from rotating to a position below the detection position P1 (fig. 20a) of the sensor 49. In the present embodiment, the lever rotation restricting pin 47e extends in a direction orthogonal to the component feeding direction. The lever rotation limiting pin 47e is engaged with the return prevention unit 42, thereby limiting the rotation of the sensor stopper 47d to a position below the detection position P1 of the sensor 49.

Next, the structure of the lead bending mechanism 23 will be described with reference to fig. 12 and 13. Fig. 12 and 13 are perspective views showing the structure of the lead bending mechanism 23.

As shown in fig. 12 and 13, the lead bending mechanism 23 includes a lead cutting portion 75 that cuts the lead L and a lead bending portion 77 that bends the lead L. The lead wire L of the axial member D fed to the supply position 5a by the feeding unit 22 is cut by the lead cutting portion 75, and bent in a substantially vertical direction by the lead bending portion 77. The lead cutting portion 75 and the lead bending portion 77 are provided on both left and right sides of the axial member body B. The lead cutting portion 75 is provided outside the lead bent portion 77 in a direction (left-right direction) orthogonal to the component feeding direction.

The lead cutting section 75 includes a fixed blade 75a and a movable blade 75b movable in the vertical direction with respect to the fixed blade 75 a. The fixed blade 75a is fixed to the main body 5c of the component supply device 5. The fixed blade 75a extends in the component feeding direction (front-rear direction) at a position above the lead wire L of the fed axial component D. The movable blades 75b are provided on both right and left outer sides of the fixed blade 75 a. The movable blade 75b extends in the vertical direction and moves upward from below the lead wire L at the supply position 5 a. The upper end of the movable blade 75b is formed in a V shape in side view. The lead cutting section 75 moves the movable blade 75b upward relative to the fixed blade 75a at the supply position 5a, and cuts the lead L while sandwiching it between the fixed blade 75a and the movable blade 75 b. Specifically, the movable knife 75b is raised to lift the lead L at the supply position 5a from below, the lead L is sandwiched between the upper end of the movable knife 75b and the fixed knife 75a, and then the movable knife 75b is further raised to cut the lead L.

The lead bent portion 77 includes a fixed molding die 77a and a movable molding die 77b that is movable in the vertical direction with respect to the fixed molding die 77 a. The fixed molding die 77a is fixed to the body portion 5c of the component supply device 5. The fixed molding die 77a has a guide groove 77aa formed in the vertical direction to guide the bending of the lead L. The guide groove 77aa is formed in a V shape in plan view. The movable molding die 77b is provided on both left and right inner sides of the fixed molding die 77 a. The movable molding die 77b extends in the vertical direction and moves upward from below the lead L at the supply position 5 a. The upper end of the movable molding die 77b is formed in a V-shape in side view. The movable molding die 77b is raised from below the lead L at the supply position 5a with respect to the fixed molding die 77a, and the lead L is guided to the guide groove 77aa and bent in a substantially vertical direction.

Next, the structure of the feeding member 31 will be described with reference to fig. 14 and 15. Fig. 14 and 15 are side views of the feeding member 31.

As shown in fig. 14 and 15, a plurality of feed claws 36 are formed at the lower portion of the feed member 31 on the opposite side (downstream side) from the rotating shaft 32 side so as to protrude downward at the same intervals as the pitch Sp of the lead wires L of the component connecting body C. The feeding claw 36 has a first feeding claw 36a formed at a downstream-side end portion of the feeding member 31, a second feeding claw 36b formed adjacently on an upstream side of the first feeding claw 36a, and a third feeding claw 36c formed adjacently on an upstream side of the second feeding claw 36 b. In the example of the feeding member 31 shown in fig. 14 and 15, seven feeding claws 36 are formed at the same intervals as the pitch Sp of the lead wires L of the component connecting body C. In fig. 14 and 15, reference numerals given to the feed pawl 36 and the surfaces formed on the feed pawl 36 are denoted by "a" to "g" in order from the downstream side.

Substantially vertical feed surfaces 37a to 37g are formed on the downstream side of the feed claws 36a to 36 g. When the feeding member 31 moves to the downstream side, the feeding surfaces 37a to 37g come into contact with the lead L of the axial component D connected as the component connector C substantially perpendicularly from the upstream side, and the component connector C moves to the downstream side. In the present embodiment, when the axial member D is present at the upstream side of the supply position 5a, the feed surface 37a of the first feed claw 36a does not feed the lead wire L at the supply position 5a to the downstream side of the supply position 5 a. When the last axial member D of the member coupling body C is positioned at the supply position 5a, the feed surface 37a of the first feed claw 36a feeds the lead wire L at the supply position 5a to a position downstream of the supply position 5 a.

Inclined surfaces 38a to 38g inclined at the same angle θ 1 so as to become higher toward the upstream side are formed on the upstream side of the feed claws 36a to 36 g. When the feeding member 31 moves to the upstream side, the inclined surfaces 38a to 38g abut from the downstream side against the lead L of the axial component D connected as the component connecting body C, and the downstream side of the feeding member 31 is rotated upward.

The feed claws 36 have substantially horizontal convex end surfaces 39a to 39g formed at convex end portions between the feed surfaces 37a to 37g and the inclined surfaces 38a to 38 g. When the feeding member 31 moves to the upstream side, the convex end surfaces 39b to 39g are in substantially horizontal contact with the lead wire L of the axial component D connected as the component connector C.

Grooves (concave surfaces) 40a to 40f are formed between the feed claws 36a to 36 g. The grooves 40b to 40f are substantially horizontally in contact with the lead L of the axial member D connected as the member connector C. The first groove 40a between the first feeding claw 36a and the second feeding claw 36b is formed deeper than the second groove 40b between the second feeding claw 36b and the third feeding claw 36 c. That is, the first groove 40a is formed such that the upper end 40aa of the first groove 40a is higher than the upper end of the second groove 40 b. The upper end 40aa of the first groove is disposed at a position higher than the lead cutting position P2 of the lead cutting portion 75 (fig. 12). The lead cutting position P2 is located on the lower surface of the fixed blade 75a (fig. 12) of the lead cutting portion 75.

In the feed claws 36a to 36f, the lengths from the grooves 40a to 40f to the convex end surfaces 39a to 39f are lengths Ha to Hf of the feed claws 36a to 36 f. Here, the length of the feed claw 36g positioned on the most upstream side (the rotating shaft 32 side) is set to the length from the groove 40f to the convex end surface 39 g.

The lengths Hb to Hg of the feed claws 36b to 36g are formed to be gradually reduced from the feed claw 36b on the downstream side toward the feed claw 36g on the rotation shaft 32 side (Hb > Hc > Hd > He > Hf > Hg). That is, the length H (length Hc) of one feeding claw 36 (for example, the feeding claw 36c) of the plurality of feeding claws 36b to 36g of the feeding member 31 is longer than the length H (length Hd) of the other feeding claw 36 (for example, the feeding claw 36d) adjacent to the rotation shaft 32 side.

Fig. 15 shows a state in which the grooves 40b to 40f are in contact with the lead L of the axial member D connected as the member connector C. In this state, the height positions Pb to Pg of the convex end surfaces 39b to 39g are formed to be higher in order from the downstream side toward the rotation shaft 32 side (Pb < Pc < Pd < Pe < Pf < Pg). The lower end portion 36aa (height position Pa) of the first feeding claw 36a is higher than the lower end portion 36ba (height position Pb) of the second feeding claw 36 b. The first feed claw 36a is formed such that a lower end 36aa of the first feed claw 36a is higher than a center height P3 of the lead wire L located in the second groove 40 b. That is, the height position Pa of the convex end surface 39a is higher than the center height P3 of the lead L located in the second groove 40 b.

Next, the configuration of the control system of the component mounter 1 will be described with reference to fig. 16. Fig. 16 is a block diagram showing the configuration of a control system of the component mounting apparatus 1. The component mounting apparatus 1 includes a mounting control section 50, a substrate conveyance mechanism 2, a component supply device 5 (component feeder), a mounting head 10, a head movement mechanism 12, a component recognition camera 13, and a substrate recognition camera 14. The assembly control unit 50 includes an assembly operation processing unit 51 and an assembly storage unit 52. The mounting storage unit 52 is a storage device, and stores mounting data including the type and shape of the axial member D mounted on the substrate 3 and the coordinates of the mounting position according to the type of the mounting substrate to be manufactured.

The mounting operation processing unit 51 controls each unit to control a component mounting operation for mounting the axial component D on the substrate 3. Each component supply device 5 is provided with a feed unit 22, a lead wire bending mechanism 23, an operation-display panel 25, and a feeder control section 26. The feeder control portion 26 controls the feeding unit 22 to perform a component feeding operation of pitch-feeding the component assembly C, and controls the lead bending mechanism 23 to perform the lead bending process.

Next, a method for manufacturing a mounting substrate by the component mounter 1 will be described with reference to fig. 17a to 17c and fig. 18a to 18 c. Fig. 17a to 17c and fig. 18a to 18c are process explanatory diagrams of the component supplying operation of the component supplying apparatus 5. In fig. 17a to 17c and fig. 18a to 18c, the feeding member 31 and the holding member 33a are simplified and shown.

The component feeding device 5 is set in a state in which the axial component D is taken out from the feeding position 5a and the feeding member 31 is returned to the stop position on the upstream side (fig. 17 a). For convenience, in fig. 17a to 17C, the axial member D connected as the member connector C only shows the lead L; in fig. 18a to 18c, only the lead L is shown except for the axial member D at the tip (downstream side). Note that the feed claw 36 and the notations (a to f) formed on the respective surfaces of the feed claw 36 are omitted when the feed claw 36 is not determined.

First, the component feeding operation is performed in the component feeding device 5. In the component supplying apparatus 5, the feeding unit 22 moves the feeding member 31 to the downstream side by the moving mechanism 34 in a state where the feeding surface 37 formed on the downstream side of each of the plurality of feeding claws 36 is brought into contact with the lead L of the axial component D from the upstream side substantially perpendicularly (component connecting body moving step) (fig. 17 b). Thereby, the axial member D at the tip end is fed to the lead bending mechanism 23.

Next, the feeding unit 22 moves the feeding member 31 to the upstream side in a state where at least two grooves 40 of the grooves 40 formed between the plurality of feeding claws 36 are in contact with the lead L of the axial member D (first moving step) (fig. 17 c). Specifically, when the groove 40 abuts against the lead L of the axial member D, at least the other upstream groove 40 also abuts against the lead L of the other axial member D. In this way, the load applied to the lead wire L can be dispersed by the contact of the two or more grooves 40 with the lead wire L.

Next, the feeding unit 22 moves the feeding member 31 to the upstream side in a state where at least two inclined surfaces 38 of the inclined surfaces 38 formed on the upstream side of each of the plurality of feeding claws 36 are in contact with the lead L of the axial member D (second moving step) (fig. 18 a). The slope 38 abuts the lead L from the downstream side, and the downstream side of the feeding member 31 is rotated upward. At this time, the load applied to the lead L can be dispersed by the lead L abutting against the two or more inclined surfaces 38.

Next, in a state where at least two of the convex end surfaces 39 formed on the convex end portions of the plurality of feed claws 36 are in contact with the lead L of the axial member D, the feed unit 22 moves the feed member 31 to the upstream side (a third moving step) (fig. 18 b). Specifically, when the convex end surface 39g of the feed claw 36g closest to the rotating shaft 32 abuts the lead wire L of the axial member D, the convex end surface 39 of at least one other feed claw 36 also abuts the lead wire L of the other axial member D. In this way, the load applied to the lead L can be dispersed by the contact of the two or more convex end surfaces 39 with the lead L.

In fig. 18c, when the feeding unit 22 returns the feeding member 31 to the upstream stop position, the convex end surface 39 passes over the lead L and rotates the downstream side of the feeding member 31 downward, and the groove 40 comes into contact with the lead L and the feeding member 31 returns to the upstream stop position. In this way, the first moving step, the second moving step, and the third moving step are feeding member returning steps, and the feeding member 31 is moved upstream by the moving mechanism 34 while the load applied to the lead L of the axial member D from the feeding member 31 is dispersed to the plurality of leads L, and is returned to the upstream stop position. While the feeding member 31 is moving upstream, the return prevention unit 42 (backward stopper mechanism) stops the component connecting body C from moving upstream.

In fig. 18c, the axial member D fed to the lead wire bending mechanism 23 by the member feeding operation is subjected to a lead wire bending process by the lead wire bending mechanism 23 (lead wire bending process step). The lead bending process may be performed in parallel with the feeding member returning process. When the lead wire bending process is completed, the mounting head 10 holds and takes out the axial member D moved to the supply position 5a by the member holding portion 11a (member taking-out step).

Next, the head moving mechanism 12 moves the mounting head 10 holding the axial member D above the substrate 3 held at the mounting work position (mounting head moving step). Next, the mounting head 10 inserts the lead L of the axial member D held by the member holding portion 11a into the through hole 3a, thereby mounting the axial member D on the substrate 3 (member mounting step). Thereafter, the supply of the axial component D by the component supply device 5 and the mounting of the mounting head 10 on the substrate 3 are repeated to manufacture a mounting substrate.

Next, a wire feeding operation for feeding the wire L1 of the last axial member D of the member coupling body C to a position downstream of the supply position 5a will be described with reference to fig. 19a to 19 e. Fig. 19a to 19e are side views of the feeding unit 22, the return prevention unit 42, and the component detection unit 46 when viewed from the inside. For convenience, in fig. 19a to 19e, the axial member D connected as the member connector C only shows the lead L.

Fig. 19a shows a state after the feeding unit 22 has fed the penultimate axial member D of the member coupling body C to the supply position 5a (after the first member feeding step ST10 described later). As shown in fig. 19a, the lead L1 of the last axial member D of the member coupling C is positioned in the second groove 40b between the second feeding claw 36b and the third feeding claw 36C.

Next, the feeding member 31 moves backward from the state shown in fig. 19a to the state shown in fig. 19 b. As shown in fig. 19b, the lead wire L1 of the last axial component D is positioned in the first slot 40a between the first feed pawl 36a and the second feed pawl 36 b.

Next, the feeding member 31 moves forward from the state of fig. 19b to the state shown in fig. 19c (after a second component feeding step ST12 described later). The lead L1 of the last axial member D is pushed forward by the feed surface 37b of the second feed claw 36b and moves to the supply position 5 a. The lead wire L1 of the last axial member D fed to the supply position 5a is cut and bent by the lead wire bending mechanism 23. The lead wire L1 left after cutting supports the lead wire detection lever 47.

Next, the feeding member 31 moves backward from the state of fig. 19c to the state shown in fig. 19 d. When the axial component D is present further upstream of the supply position 5a, the feeding member 31 is supported by the lead wire L of the axial component D and is in a substantially horizontal state. On the other hand, as shown in fig. 19D, when there is no axial direction component D at the upstream side of the supply position 5a, that is, when the last axial direction component D is located at the supply position 5a, the feeding member 31 is not supported by the lead wire L and rotates downward around the rotation shaft 32. At this time, the rotation of the upper end 36ab of the first feed pawl 36a to a position below the level of the lead L1 at the supply position 5a is restricted by the rotation restriction pin 71. Thus, the first feeding surface 37a of the first feeding claw 36a is disposed at a height capable of pushing the lead wire L1 to a position downstream of the feeding position 5 a.

Finally, the feeding member 31 moves forward from the state of fig. 19d to the state shown in fig. 19e (after the lead wire discharging step ST14 described later). The first feed claw 36a (the first feed surface 37a) moves from the upstream side to the downstream side of the supply position 5a, and feeds the lead L1 of the last axial member D of the member coupling body C to the downstream side of the supply position 5 a. That is, the lead L1 left after being cut at the supply position 5a is pushed out to the downstream side of the supply position 5 a. Thereby, the lead wire detection lever 47 supported by the lead wire L1 rotates downward. The lead wire detection lever 47 rotates to a position below the height of the lead wire at the supply position 5a, the sensor stopper 47d rotates to shield the sensor 49 from light, and the sensor 49 detects that the lead wire L is not present at the supply position 5 a. That is, the component detecting unit 46 detects that the supply of the last axial component D of the component coupling body C is completed.

When the component connecting body C is fed to the downstream side pitch, the lead L moving to the downstream side abuts against the inclined surface S6 of the protruding portion 47b and the lead detection lever 47 is rotated upward, so that the lead detection lever 47 does not interfere with the movement of the component connecting body C. On the other hand, when the component connector C attempts to follow the feeding member 31 moving upstream and move upstream (when the component connector C attempts to return), the substantially perpendicular surface S5 on the downstream side of the protruding portion 47b of the lead detection lever 47 contacts the lead L substantially perpendicularly, and movement of the component connector C is stopped. The lead wire detecting lever 47 constitutes a retreat preventing mechanism that prevents the component connecting body C from moving to the downstream side and prevents the component connecting body C from moving to the upstream side.

In the state from fig. 19C to fig. 19d, since the lead L is not present at the upstream side of the supply position 5a, the return prevention lever 42a may not prevent the member connecting body C from moving to the upstream side. On the other hand, the protrusion 47b stops the movement of the lead L1 to the upstream side, and the lead detection lever 47 can stop the movement of the component connecting body C to the upstream side. Therefore, particularly when the lead L is not present at the upstream side of the supply position 5a, the protruding portion 47b of the lead detection lever 47 has an effect of restraining the movement of the member coupling body C toward the upstream side.

Fig. 20a is a side view of the sensor 49 when the sensor stopper 47d is positioned above the detection position P1. Fig. 20b is a side view of the sensor 49 with the sensor stopper 47d at the detection position P1.

When the lead wire L is present at the supply position 5a, that is, when the lead wire detection lever 47 is supported by the lead wire L, the sensor stopper 47d is positioned above the detection position P1 as shown in fig. 20 a. Therefore, the sensor 49 detects the presence of the lead wire L at the supply position 5 a.

On the other hand, when the lead wire L1 of the last axial member D of the member coupling body C is fed to the position downstream of the supply position 5a, that is, when the lead wire detection lever 47 is not supported by the lead wire L, the sensor stopper 47D is positioned at the detection position P1 as shown in fig. 20 b. Since the light is blocked by the sensor stopper 47d, the sensor 49 detects that the lead wire L is not present at the supply position 5 a.

Next, a component supply method will be described with reference to fig. 21. Fig. 21 is a flowchart showing a component supply method. As shown in fig. 21, the component supplying method includes component feeding processes ST10, ST12, ST14, a component detecting process ST20, and a lead cutting process ST 30.

The component feeding processes ST10 and ST12 are processes of feeding the axial component to the supply position 5a by reciprocating the feeding member 31 in the component feeding direction. The component detecting step ST20 is a step of detecting the presence or absence of the lead L of the axial component D at the supply position 5 a. The lead cutting step ST30 is a step of cutting the lead L of the axial member D fed to the supply position 5a by the member feeding steps ST10 and ST 12.

The component feeding processes ST10, ST12, ST14 include a first component feeding process ST10, a second component feeding process ST12, and a lead wire discharging process ST 14. The first component feeding step ST10 feeds the penultimate axial component D of the component assembly C from a position (not shown) where it is supplied to the component supply device 5 to the supply position 5 a. After the first component feeding process ST10, the second component feeding process ST12 feeds the last axial component D of the component coupling body C to the supply position 5 a. After the second component feeding step ST12, the feeding member 31 ejects and discharges the lead L1 cut in the lead cutting step ST30 to a position downstream of the supply position 5a in the lead ejecting step ST 14.

In the first component feeding step ST10, when the feeding member 31 moves from the downstream side to the upstream side in the component feeding direction, the feeding member 31 moves in a state of being separated from the lead L at the supply position 5 a. That is, when the feeding member 31 moves from the downstream side to the upstream side in the component feeding direction, the feeding member 31 moves so as not to interfere with the lead L at the supply position 5 a.

In the present embodiment, in the first component feeding step ST10, when the feeding member 31 moves from the upstream side to the downstream side in the component feeding direction, the downstream end portion of the feeding member 31 (the lower end portion 36aa of the first feeding claw 36 a) moves to a position higher than the center height P4 of the lead L at the supply position 5 a. That is, in the present embodiment, in the first component feeding step ST10, when the feeding member 31 moves from the upstream side to the downstream side in the component feeding direction, the first feeding claw 36a does not push out the lead wire L at the supply position 5a to the downstream side. In another embodiment, in the first component feeding step ST10, the first feed claw 36a may have a function of pushing out the lead L at the supply position 5a to the downstream side.

After the first component feeding step ST10, in the component detecting step ST20, the lead wire detecting lever 47 is supported by the lead wire L, and the component detecting portion 46 detects that the lead wire L of the penultimate axial component D is present at the supply position 5 a. After the component detecting step ST20, the lead wire L fed to the penultimate axial component D at the supply position 5a is cut by a lead cutting step ST 30.

After the lead cutting process ST30, the last axial member D is fed to the supply position 5a by the second member feeding process ST 12. After the second component feeding process ST12, when the feeding member 31 moves from the downstream side to the upstream side in the component feeding direction, the lead wire detecting lever 47 restricts the movement of the lead wire L1 at the supply position 5a from the downstream side to the upstream side in the component feeding direction in accordance with the movement of the feeding member 31. After the second component feeding step ST12, in the component detecting step ST20, the lead wire detecting lever 47 is supported by the lead wire L1, and the component detecting portion 46 detects the presence of the lead wire L1 at the supply position 5 a. After the component detecting step ST20, the lead wire L1 of the last axial component D fed to the supply position 5a is cut by the lead wire cutting step ST 30.

After the lead cutting step ST30, the feeding member 31 pushes and discharges the lead L1 to the downstream side of the supply position 5a in the lead discharging step ST 14. After the lead wire discharging step ST14, in the component detecting step ST20, the lead wire detecting lever 47 is not supported by the lead wire L1, and the component detecting portion 46 detects that the lead wire L1 is not present at the supply position 5 a. This completes the component supply of the component connection body C.

According to the component feeding device 5 of the present embodiment, the first groove 40a between the first feeding claw 36a and the second feeding claw 36b is formed deeper than the second groove 40b between the second feeding claw 36b and the third feeding claw 36 c. The upper end 40aa of the first groove 40a is arranged at a position higher than the lead cutting position P2 of the lead cutting portion 75 (fig. 15). The first feed claw 36a moves from the upstream side to the downstream side of the supply position 5a, and feeds the lead L1 of the last axial member D of the member coupling body C to the downstream side of the supply position 5 a.

Thereby, the first feed claw 36a moves from the upstream side to the downstream side of the supply position 5a, and the lead L1 of the last axial member D located at the supply position 5a can be fed to the downstream side by the first feed claw 36 a. Thus, since no lead wire of the axial member D is present at the supply position 5a, the member detection unit 46 can easily detect that the supply of the axial member D of the member coupling body C is completed. Further, the upper end portion 40aa of the first groove 40a is disposed at a position higher than the lead cutting position P2 of the lead cutting portion 75, and the feed member 31 can be prevented from being lifted by the lead L lifted to the lead cutting position P2.

In addition, the feeding member 31 is formed such that the lower end portion 36aa of the first feeding claw 36a is higher than the lower end portion 36ba of the second feeding claw 36 b.

Accordingly, when the axial component D is present at the upstream side of the supply position 5a, the first feed claw 36a can be prevented from contacting the lead L at the supply position 5a when the feeding member 31 moves from the downstream side to the upstream side in the component feeding direction. Therefore, the lead wire L at the supply position 5a can be prevented from moving to the upstream side of the supply position 5a in accordance with the movement of the feeding member 31.

The first feeding claw 36a is formed such that the lower end 36aa of the first feeding claw 36a is higher than the center P3 of the lead wire L located in the second groove 40 b.

Accordingly, when the axial member D is present further upstream of the supply position 5a, the first feed claw 36a can be prevented from pushing out the lead L located at the supply position 5 a. This prevents the component detection unit 46 from determining that the lead wire L is not present at the supply position 5a even if the axial component D is present at a position upstream of the supply position 5 a.

The feeding member 31 is rotatably held by the rotating shaft 32, and the upper end 36ab of the first feeding claw 36a is restricted from rotating to a position below the height of the lead wire L at the supply position 5a by a rotation restricting pin 71 that restricts the downward rotation of the feeding member 31.

Thus, the first feed claw 36a can more reliably apply the external force to the lead wire L1 of the last axial member D located at the supply position 5a, and can more reliably feed the lead wire L1 to the downstream side.

The component detecting unit 46 includes a lead detection lever 47 supported by the lead L at the supply position 5a, a lever supporting portion 48 rotatably supporting the lead detection lever 47, and a sensor 49 detecting rotation of the lead detection lever 47.

Thus, the presence or absence of the lead L at the supply position 5a can be easily detected by detecting the rotation of the lead detection lever 47.

The lead wire detection lever 47 has a lead wire contact portion 47a supported by the lead wire L, and a projecting portion 47b projecting downward at a position upstream of the lead wire contact portion 47 a.

This prevents the lead wire L at the supply position 5a from being returned rearward along with the movement of the feeding member 31 when the feeding member 31 moves upstream.

The lead wire detection lever 47 is restricted from rotating to a position below the detection position P1 of the sensor 49 by a lever rotation restriction pin 47e that restricts rotation of the lead wire detection lever 47.

This enables more reliable detection of the presence or absence of the lead L at the supply position 5 a.

In addition, the component supplying method according to the present embodiment includes component feeding processes ST10, ST12, ST14, a component detecting process ST20, and a lead cutting process ST 30. The component feeding processes ST10, ST12 feed the axial component D to the supply position 5a by reciprocating the feeding member 31 in the component feeding direction. The component detecting step ST20 detects the presence or absence of the lead L of the axial component D at the supply position 5 a. The lead cutting process ST30 cuts the lead L of the axial member D fed to the supply position 5a by the member feeding processes ST10 and ST 12. The component feeding processes ST10, ST12, ST14 include a first component feeding process ST10, a second component feeding process ST12, and a lead wire discharging process ST 14. The first component feeding step ST10 feeds the second last axial component D of the component coupling body C to which the plurality of axial components D are coupled to the supply position 5 a. After the first component feeding step ST10, the second component feeding step ST12 feeds the last axial component D of the component connecting body C to the supply position 5 a. After the second component feeding step ST12, the feeding member 31 ejects and discharges the lead L1 cut in the lead cutting step ST30 to a position downstream of the supply position 5a in the lead ejecting step ST 14.

Thus, the lead L1 of the last axial member D located at the supply position 5a can be fed downstream, and the lead L1 of the axial member D is not present at the supply position 5a, so that the completion of the supply of the axial member D of the member coupling body C can be easily detected.

In the first component feeding step ST10, when the feeding member 31 moves from the downstream side to the upstream side in the component feeding direction, the feeding member 31 moves in a state of being separated from the lead L at the supply position 5 a.

This prevents the feeding member 31 from contacting the lead L at the supply position 5a when the feeding member 31 moves from the downstream side to the upstream side in the component feeding direction. Therefore, the lead wire L at the supply position 5a can be prevented from moving to the upstream side of the supply position 5a in accordance with the movement of the feeding member 31.

In the first component feeding step ST10, when the feeding member 31 moves from the upstream side to the downstream side in the component feeding direction, the downstream end of the feeding member 31 moves to a position higher than the center height P4 of the lead L at the feeding position 5 a.

Accordingly, when the axial member D is present further upstream of the supply position 5a, the feed member 31 can be prevented from pushing out the lead L located at the supply position 5 a. This prevents the absence of the lead wire L from being detected at the supply position 5a even if the axial member D is present at the upstream side of the supply position 5 a.

Further, after the second component feeding step ST12, when the feeding member 31 moves from the downstream side to the upstream side in the component feeding direction, the lead wire detecting lever 47 restricts the movement of the lead wire L1 at the supply position 5a from the downstream side to the upstream side in the component feeding direction in accordance with the movement of the feeding member 31.

This prevents the lead wire L1 at the supply position 5a from returning rearward as the feeding member 31 moves when the feeding member 31 moves upstream.

The feeding unit 22 includes a coupling member 33b that couples the pair of holding members 33 a.

Thus, the pair of holding members 33a can be fixed by the coupling member 33b, and therefore the holding members 33a can be integrated. This can prevent the pair of holding members 33a from being fixed to the connecting member 33c in a mutually offset manner. Therefore, the reproducibility of the mounting position of the holding member 33a can be improved, and the pair of holding members 33a can be easily attached to and detached from the connecting member 33 c. In addition, the feeding member 31 held by the pair of holding members 33a can be prevented from contacting other members.

The pair of holding members 33a have fixing portions 33aa extending in the component feeding direction and fixed to the coupling member 33b, and the coupling member 33b has a coupling portion 33ba extending in the component feeding direction and coupled to the pair of fixing portions 33 aa.

Thus, the fixing portion 33aa and the connecting portion 33ba extend in the component feeding direction, and the pair of holding members 33a that hold the pair of feeding members 31 extending in the component feeding direction can be more reliably connected by the connecting member 33 b.

The pair of holding members 33a are coupled at a plurality of positions by coupling members 33b, respectively.

This prevents the pair of holding members 33a from being coupled by the coupling member 33b in a state of being offset from each other.

The coupling member 33b and the connecting member 33c have positioning portions 61b and 62b positioned with each other.

Thus, the positioning portions 61b and 62b of the coupling member 33b and the connecting member 33c eliminate the need to position the pair of holding members 33a with respect to the connecting member 33 c. By positioning the coupling member 33b and the connecting member 33c, the pair of holding members 33a can be easily attached to the connecting member 33 c. Therefore, the workability of assembling the feeding unit 22 can be improved.

The connecting member 33c has a front side surface S2 extending in the vertical direction. The pair of holding members 33a each have a positioning surface S1 extending in the vertical direction and abutting against the front side surface S2 of the connecting member 33c in the front-rear direction. The positioning portion 61b of the coupling member 33b has a through hole penetrating in the vertical direction, and a positioning pin 63 for positioning the coupling member 33b and the connecting member 33c with each other is fitted into the through hole. The positioning portion 62b of the connecting member 33c has a through hole penetrating in the vertical direction, and the positioning pin 63 is inserted into the through hole to regulate the movement in the width direction orthogonal to the front-rear direction. The through hole of the connecting member 33c is formed to have a length in the front-rear direction longer than a length in the width direction.

Thus, the holding member 33a can be positioned in the width direction with respect to the connecting member 33c by inserting the positioning pin 63 into the through holes of the connecting member 33b and the connecting member 33 c. Further, the positioning surface S1 of the holding member 33a is brought into contact with the front side surface S2 of the connecting member 33c, whereby the holding member 33a can be positioned in the front-rear direction with respect to the connecting member 33 c. The length of the through hole of the connecting member 33c in the front-rear direction is longer than the length in the width direction. Therefore, the holding member 33a is moved in the front-rear direction in a state where the positioning pin 63 is inserted into the through holes of the connecting member 33b and the connecting member 33c, and the holding member 33a can be more easily positioned with respect to the connecting member 33 c.

The return prevention unit 42 has a rod coupling member 45 that couples the pair of rod holding members 44.

Thus, the pair of lever holding members 44 can be fixed by the lever coupling member 45, and therefore the lever holding members 44 can be integrated. This can prevent the pair of lever holding members 44 from being fixed to the main body portion 5c of the component supply device 5 so as to be displaced from each other. Therefore, the reproducibility of the mounting position of the lever holding members 44 can be improved, and the pair of lever holding members 44 can be easily attached to and detached from the main body portion 5c of the component supply device 5. In addition, the return prevention lever 42a held by the pair of lever holding members 44 can be prevented from contacting other members.

The pair of lever holding members 44 have recesses 44a, respectively, and the recesses 44a are fitted to the lever coupling member 45 while restricting the movement of the lever coupling member 45 in the front-rear direction with respect to the lever holding members 44.

This prevents the pair of lever holding members 44 from being coupled to each other by the lever coupling member 45 in a state of being offset from each other.

Further, the pair of lever holding members 44 are positioned relative to each other with respect to the main body portion 5c of the component supply device 5.

This can prevent the pair of lever holding members 44 from being fixed to the main body portion 5c of the component supply device 5 in a displaced manner. Further, since the number of fixing positions of the pair of rod holding members 44 to the main body portion 5c of the component supply device 5 can be reduced, workability of attaching and detaching the pair of rod holding members 44 can be improved.
