Description

Circuit board feeder of circuit board manufacturing equipment {PCB FEEDING APPARATUS OF PCB MANUFACTURING MACHINE}

The present invention relates to a circuit board transfer device of a circuit board manufacturing apparatus for producing a large amount of circuit boards widely used in various electrical and electronic products, and more particularly to a circuit component assembly mechanism for assembling circuit components on a circuit board. When provided with a plurality, it is to improve the transfer of the circuit board from the circuit board supply means to the plurality of circuit board pedestal and the circuit board discharge means to improve the circuit board.

In general, the circuit board manufacturing apparatus has a circuit component assembly apparatus 100 at the center, as shown in FIG. 1, before the circuit board supply means 200, and after that the circuit board discharge means 300. In order to improve productivity, the circuit component assembly apparatus 100 is provided with a plurality of circuit component assembly mechanisms 101 and 102.

In this case, the plurality of circuit component assembly mechanisms 101 and 102 have respective circuit board pedestals 110 and 120, that is, the primary circuit board pedestal 110 and the secondary circuit board pedestal 120. Several transfer devices are known for transferring and feeding circuit boards on these circuit board pedestals 110 and 120.

For example, after installing a pair of guide rails from the circuit board supply means to the circuit board support, and placing the circuit board on the rail, a squeezing rod reciprocating along the longitudinal direction of the rail transports the circuit board. There is a holding means to move two sheets at a time.

Another example is Utility Model Publication No. 92-22479, which allows the tongs to pick up two circuit boards waiting side by side in the circuit board supply means, and the tongs are moved by a cylinder. The moving piece, which is fixed to the moving piece that is retracted and whose tongs are fixed, moves the cylinder forward and is placed on the plurality of circuit board pedestals, and the moving piece that has moved forward retreats back to its original position.

However, the above-mentioned conventional circuit board transfer devices point out the following problems.

That is, in the case of the former, when the conveying speed is lowered and the width of the guide rail and the joint part are not assembled precisely, when the edges of the circuit board collide with each other at the joint part, a feeding defect occurs or the circuit board is damaged. In the latter case, the tongs pick up the circuit board and then transport it, so not only is the work speed very slow, but also the moving pieces are reciprocated from the front of the circuit board rest so that the field of view of the circuit board pedestal may be reduced. If the cover was to be screened and the circuit board support was to be inspected or repaired, there would be a risk of a safety accident if the transfer tray malfunctioned.

On the other hand, in recent years, a belt transfer structure has been developed that can transfer a circuit board safely and quickly without using a guide rail or push rod.

That is, with a pair of guide rails capable of width adjustment, a driving belt is installed under each of the guide rails so that both ends of the circuit board are transported in the direction in which the driving belt rotates while being mounted on the driving belt.

In the case of a plurality of circuit board pedestals, such a belt feeder also requires a feeding means for supplying one circuit board to each circuit board pedestal and collecting them one by one.

In particular, the primary circuit board bracket and the secondary circuit board bracket are composed of disks because they must be able to rotate from time to time, and the guide rails must be installed in parallel within the size of the disks, so that the length of the circuit board brackets should not exceed the diameter of the disk. It can't be long.

Therefore, there is a considerable distance between the guide rail of the primary side circuit board pedestal and the secondary side circuit board pedestal, and there is a problem that a circuit board having a length smaller than this distance cannot be transferred.

The present invention has been made in view of the above-mentioned problems in the prior art, and the main object of the present invention is to have a plurality of circuit board pedestals, primarily transferred to the second circuit board pedestal through the first circuit board pedestal, Secondly, the circuit board can be transferred to the first circuit board support, and further, the auxiliary transfer means is provided between the first circuit board support and the second circuit board support so that even a relatively short circuit board passes between them. I want to make sure there is no crowd.

The circuit board conveying apparatus of the circuit board manufacturing apparatus of the present invention for achieving the above object is a left rotation disk member and a right rotation disk member which can be rotated in the horizontal direction by the respective driving means arranged left and right; Each base plate member having a rectangular opening at its center while being fixed on each of the left and right rotating disc members; The base plate member is fixed in parallel with the upper inner side and the lower inner side in the opening of the base plate, and the inner side jaws are formed in the inner side facing each other along the longitudinal direction, and the drive side pin shaft set and the driven side pin shaft set at both ends at the inner side jaws. A guide rail member configured to extend a driving belt, and to drive the driving side pin shaft set as a driving motor; A shaft rod fixed to a pair of bearing members on an outer side of the guide rail member on one side of the base plate member, a rotation arm fixed to both ends of the shaft rod with a stopper and a positioning pin at an outer end thereof, and at both ends of the shaft rod. A pair of left and right pairs of first and second side circuit board supports which include a circuit board stop means made of a pressing piece that is attached to the shaft and rotates the shaft; It is characterized by comprising an auxiliary transfer means provided on an extension line of the upper left and right guide rail members and the lower left and right guide rail members between the primary circuit board support and the secondary circuit board support. .

In addition, the auxiliary transport means 130 is the upper left, right guide rail members 113, 123 and the lower left between the primary circuit board support 110 and the secondary circuit board support 120 described above. On the extension line of the right guide rail member 113, 123 is provided.

At this time, the auxiliary transport means 130 is between the upper auxiliary transport mechanism 132 provided between the upper left and right guide rail members 113 and 123, and between the lower left and right guide rail members 113 and 123. It consists of a lower auxiliary transfer mechanism 131 provided in.

The upper subsidiary feed mechanism 132 has a vertical piece 132a and a fixing member 132b which can be fixed to the bottom, and a plurality of idle rollers condensed in a horizontal direction from the vertical piece 132a of the fixing member ( 132c, and a driving roller 132d condensed at a position close to the idle roller 132c, and the lower auxiliary transport mechanism 131 is formed in a symmetrical form facing the upper auxiliary transport mechanism 132.

On the other hand, the auxiliary transport means 130 of the present invention is not installed between the primary circuit board support 110 and the secondary circuit board support 120, as shown in Figure 5 circuit components assembly mechanism 101 (102) ) Can be installed on its bottom.

In this case, as shown in FIG. 6, when the assembly of the circuit parts is lowered, that is, the moment when the circuit board is transferred, the circuit part assembly mechanism is lowered to lower the bottom of the primary circuit board support 110 and the secondary circuit board support 120. As soon as the transfer of the circuit board is completed, it rises immediately.

The following describes the operating state of the present invention configured as described above.

First, the circuit board P is transported along the supply guide rail 201 of the supply means 200 to be sent to the primary side circuit board pedestal 110. At this time, the supply guide rail of the supply means 200 201 is a pressing piece of the stop means 117 in which the protruding portion 202 descended by an elevating mechanism (not shown) provided at the lower end thereof and protruded downward from the end thereof is located on the primary circuit board pedestal 110. Hold down 117c).

When the pressing piece 117c stuck to the shaft rod 117b is pressed, the opposite rotation arm 117f is lifted, and thus the stopper 117d and the position fixing pin 117e which protrude from the end of the rotation arm 117f. Is not disturbed by the circuit board which is conveyed along the guide rail member 113.

In addition, the discharge guide rail 301 of the discharge means unit 300 is also provided to the elevating mechanism (not shown) provided at the lower end thereof in the same manner as when the supply guide rail 201 of the supply means unit 200 descends. As a result, the protrusion 302 descending from the end thereof is pressed down by the pressing piece 127c of the stop means 127 in the secondary circuit board support 120.

At this time, as in the previous case, when the pressing piece 127c stuck to the shaft 127b is pressed, the rotating arm 127f on the opposite side is lifted, and thus the position with the stopper 127d protruding from the end of the rotating arm 127f. The fixing pin 127e does not interfere with the circuit board transferred along the guide rail member 123.

In this state, when the circuit board P is introduced into the primary circuit board pedestal 110 by the supply guide rail 201, both ends of the front end portion of the circuit board P are in the upper side (as shown in Fig. 2). It is conveyed while being mounted on the drive belt 114 in the inner guide portion (113a) of the guide rail member 113 and the lower guide rail member 113 of the same.

If the transfer continues, the distal end of the circuit board P is out of the driving belt 114 of the primary circuit board support 110, and the front end of the circuit board P is already idle roller of the auxiliary transport means 130. 131c and 132c and the driving rollers 131d and 132d, and the rear end of the circuit board P is out of the driving belt 114 of the primary circuit board support 110. The stop portion of P passes between the idle rollers 131c and 132c of the auxiliary transfer means 130 and the driving rollers 131d and 132d, wherein the distal end portion of the circuit board P is a secondary circuit board supporter ( It is introduced into the drive belt 124 of the guide rail member 123 of 120.

When the rear end of the circuit board P passes the auxiliary transport means 130, the discharge guide rail 301 of the discharge means part 300 is lifted by the lifting mechanism, and the discharge guide rail 301 is When rising, the protrusion 302 at the end of the discharge guide rail 301 presses down on the pressing piece 127c, and ascends, so that the end of the pivoting arm 127f is half lowered, and thus the stopper protrudes downward from the end of the pivoting arm. When the circuit board touches 127d, the movement is completed, and when the pivot arm 127f is lowered in that state, the position fixing pin 127e which protrudes at the end of both pivot arms 127f is the circuit board P. The position is fixed precisely by leaning in the hole formed in the four ears.

In this way, after one circuit board P is placed on the secondary circuit board pedestal 120 through the primary circuit board pedestal 110 and held in position, another circuit board P is then supplied again. 20 is sent to the primary circuit board pedestal 110, and both ends of the front end portion of the circuit board P are guide rail members 113 of the upper side (the same direction as below in the drawing) as shown in FIG. When the inner guide portion 113a of the lower side guide rail member 113 starts to enter while being mounted on the driving belt 114, the supply guide rail 201 of the supply means 200 is lifted by the lifting mechanism, and the supply When the guide rail 201 is raised, the protrusion 202 at the end of the feed guide rail 201 presses the pressing piece 117c and then rises, so that the stopper 117d beneath it when the end of the pivoting arm 117f is lowered halfway. ), The circuit board touches and the movement is completed. 117f is further lowered so that the position fixing pins 117e protruding from the ends of both of the pivoting arms 117f are inserted into the holes formed in the four ears of the circuit board P to fix the position accurately.

In this way, when one circuit board P is supplied to the primary circuit board bracket 110 and the secondary circuit board bracket 120, respectively, the circuit component assembly mechanisms 101 and 102 of both circuits are respectively provided. It will automatically assemble the circuit components on the circuit board.

After assembling all the circuit components, the supply guide rails 201 and the discharge guide rails 301 are lowered by the elevating mechanism, and the protrusions 202 and 302 protruding at their respective ends are the circuit board stop means 117. Pressing the pressing pieces 117c and 127c of 127 causes the pivoting arms 117f and 127f to rise, and the pivoting arms 117f and 127f ascend so that the stoppers 117d and 127d are positioned. The 117e and 127e are raised so that the circuit board can not be moved easily.

As the supply guide rail 201 and the discharge guide rail 301 are lowered as described above, when the switches are turned on, the respective driving motors 118 and 128 operate to drive the left and right guide rail members 113 and 123. The side pinshaft sets 115 and 125 are driven, and they drive the drive belts 114 and 124, thereby transferring the circuit boards to the discharge guide rail 301 again.

That is, the circuit board on the secondary circuit board supporter 120 is first immediately discharged to the left by the drive belt 124 of the upper and lower guide rail members 123 and is discharged on the discharge guide rail 301.

In addition, the circuit board in the primary circuit board support 110 is first sent to the primary circuit board support 110 by the drive belts of the upper and lower guide rail members 113, and the front end thereof is the auxiliary transport means 130. Short circuit board is also conveyed without difficulty because it is carried between the idle rollers 131c and 132c and the driving rollers 131d and 132d, and the discharge guide rail from the secondary circuit board support 120 is The transfer to 301 is the same as before, and after this, new circuit boards are transferred to the primary circuit board pedestal 110 and the secondary circuit board pedestal 120 again as before. The process of automatic assembly is repeated.

For reference, as shown in FIG. 14, the circuit board stop means 117 also fixes the stopper 127d to one pivot arm 117f, and the positioning pin 117e is also fixed to another pivot arm 117g. It may also be carried out.

As described in detail above, the present invention provides a circuit board manufacturing apparatus having a plurality of circuit component insertion mechanisms, comprising: a primary side circuit board support and a secondary side circuit board support; A pair of guide rail members are installed by using the guide rail members, and since the guide rail members are capable of transferring the circuit board by the driving belt, the circuit board is moved from the supply guide rail of the supply means to the base circuit board support, and the primary circuit board. From the pedestal to the secondary circuit board pedestal, and the secondary circuit board pedestal from the discharge means portion of the discharge guide rail is transferred to eliminate the need for a conventional circuit board bar or transfer table.

Particularly, since a separate auxiliary transfer means is provided between the primary circuit board support and the secondary circuit board support, even if the length of the circuit board is short, the moment is transferred from the primary circuit board support to the secondary circuit board support. Jamming is prevented in advance, and safety and compatibility are great advantages.
