The pulley 236 and the pulley 238 of each vertical frame portion are in turn operatively coupled to each other by the conveyor belt 240.

The conveyor belt 240 is guided to the upper portion of the vertical frame portion, respectively, and extends in the horizontal direction along the upper horizontal portion of the vertical frame portion 218. Both sides of the printed wiring board 104 are to be supported on the upper horizontal extension portion 242 of the conveyor belt. Pulley 238 is driven by a motor different from that of pulley 236.

The printed wiring board feeder 200 also includes a unit for pushing the printed wiring board toward the X-table 102, which is shown in detail in FIG. The printed wiring and the pushing unit 244 includes a guide plate 246 fixed to the vertical frame portion 218A, which has a guide groove 248 (Fig. 8) formed along the upper horizontal portion of the frame portion 218A. The spline shaft 250 is disposed on the guide groove 248 to allow rotation and sliding in the axial direction thereof. The spline shaft 250 is fixed to one end (front end) of the first arm 254 and is connected to the other end thereof (rear end) through the first claw member 250 and the second arm 258. It has two cloth members 256.

An air cylinder 259 is fixed to the guide plate 246, and the piston rod 26 of the cylinder is connected to the front end of the spline shaft 250 through the connecting plate 262. In addition, the spline shaft 250 is pivotally connected to the connecting plate 262 to be freely rotated.

The spline shaft 250 extends through the gear support block 264 fixed to the guide plate 246, and has a pinion 266 fitted to the support block 264, as shown in FIG. A rack 268 coupled with 266 is provided to be movable in a vertical direction with respect to the gear support block 264. Slide pinion 266 in the axial direction so that axial motion of spline shaft 250 is not inhibited, and as indicated by the dashed line in FIG. 7, rack 268 is driven by a spring (not shown). It is forced downward.

Let it be. The stopper block 270 has a stopper bolt 272 which is to be in contact with the lower end surface of the rack 268. The spline shaft 250 has a guide groove 274 for the purpose of guiding forward movement.

Then, a description will now be given of the operation of the printed wiring board supplying device 200 described above.

The air cylinder 216 extends during operation of the X-table 102 such that the frame 210 is in the raised position as shown in FIG. This in turn results in the frame 210 ensuring smooth movement of the X-table 102. In the raised position of the frame 210, the first and second cloth members 252 and 256 raise their distal ends, as indicated by solid lines of FIGS. 8 and 9, respectively, so that they are printed wiring board 104. Do not combine with At this time, the conveyor belt 240 is operated to set the subsequent printed wiring board supplied from the printed wiring board supply unit (not shown) to a predetermined position between the first and second cloth members 252 and 256. Then it stops.

While the motion of the X-table 102 is stopped to feed the next printed wiring board, the frame 210 is in the lowered position as shown in FIGS. 4 and 5, so that the printed wiring board is supported. The upper horizontal portion of each conveyor belt 240 present is at the same height as the rails 217 (FIGS. 4 and 8) of the X-table 102 to support the printed wiring board thereon. In the lowered position, the rack 268 in the gear support block 264 is brought into contact with the stopper bolt 272 as indicated by the dashed line in FIG. 7 and moved as indicated by arrow D, engaging with them.

This in turn causes the spline shaft 250 to rotate in the same direction, so that the first and second claw members 252 and 256, respectively, are indicated by dashed lines in FIGS. 8 and 9, respectively, of the printed wiring board 104. FIG. To engage the rear end. More specifically, the first claw member 252 is combined with the printed wiring board located on the rail 217 of the X-table 102 so as to be supplied to a predetermined central position of the X-table, and also the second claw member 256 is coupled to the next printed wiring board supplied from the printed wiring board supply unit on the conveyor belt 240. The air cylinder 259 then operates to extend the piston rod 260 so that the spline shaft 250 and the claw members 252 and 256 are moved in the direction of motion of the printed wiring board. This, in turn, causes the first cloth member 252 to deliver the printed wiring board 104 to a predetermined central position of the X-table 102 and the second cloth member 256 to transfer the next printed wiring board 104. This results in feeding to the end of the rail 217 of the X-table 102.

Thus, it can be seen that the printed wiring board supply device 200 can easily and reliably feed the printed wiring board to the X-table.

[Electronic component insertion mechanism]

Now, the above-described electronic component insertion apparatus 300 will be described.

The insertion head unit 308 is comprised of the directions shown in FIGS. 10-12. The insertion head unit 308 shown in Figs. 10 to 12 is for handling electronic components having leads such as single-in-line package ICs (SIP-ICs).

The insertion head unit 308 includes a vertical axis 314 arranged to be movable in the vertical direction and a support block 316 fixed on the lower end of the vertical axis 314. The support block 316 has a pair of clamping members 318 pivotally mounted thereon by a support pin 320. The pivoting movement of each clamping member 318 is limited to a predetermined range by stoppers 322 and 324 spirally inserted into the support block 316. The pin stopper 322 also has compression springs 326 fitted thereon that make the clamping member 318 constant in the direction in which the lower ends thereof are separated from each other. The support block 316 also has a working air cylinder 328 corresponding to the member 318. Each air cylinder 328 has a cylinder rod 330 which is brought into contact with the inside of the upper end of the corresponding clamping member 318. It causes the lower end of the clamping member to come close to each other to firmly clamp the lead 332 of the SIP-IC 334 as each air cylinder 328 pushes the upper end of the member 318 in the direction of arrow G.

As shown in FIG. 12, the clamping member 318 is formed on the inner surface 336 of the opposing lower end portion and has a guide groove 338 in which the SIP-IC 334 wing the lead 332.

The support block 316 is then provided with a push rod 340 that can move vertically within the space defined between the clamping members 318. As shown in FIG. 11, the pushrod 340 has a lower end formed to have a larger width corresponding to the length of the SIP-IC 334. The push rod 340 is vertically moved by an actuator (not shown) disposed in the vertical axis 314.

As described above, the operation of the air cylinder 328 closes the lower end of the clamping member 318 to secure the lead 332 of the SIP-IC 334 therebetween. At this time, the lead 332 is engaged in the guide groove 338 of the opposing surface 336 of the member 318. Then, since the clamping member 318 moves downward to the lowering of the vertical axis 314, the lead 332 of the SIP-IC 334 is inserted into the hole of the printed wiring board 104, such as the dotted lines of Figs. It begins to be.

The pushrod 340 is then lowered to press the body of the SIP-IC 334 to insert the lead 334 into the plate 104. At this time, the clamping member 318 is returned to its original state or opened at its lower end. Then, the rod is lowered further to insert the printed wiring board 104 to the lead 332 sufficiently and firmly.

13 to 15 show a modification of the insertion head unit of FIGS. 10 to 12, which is in contact with the inner surface of the lower end of the clamping member in the body of the electronic component and is opposite to the surface of the clamping member having the lead of the component. It is configured to engage with the inside. The insertion head unit is also for handling electronic components having a plurality of pins or leads, such as pin connectors.

In particular, the one clamping member 318 has an inner surface 336A formed in a shape that is flat enough to contact the side of the main body 344 of the electronic component 334, such as a pin connector, and the other clamping member 318 is a component ( It is formed to support the downwardly protruding lead or pin 332 of 334 and has an inner surface 336B opposite surface 336A. For this purpose, the inner surface 336B has a projection 346 formed therein with a guide groove 338 for placing the pin 332 therein. The pushrod is formed to have a recess 347 at its lower end that engages the pin 332 of the pin connector 334. The remaining portion of the insertion head unit 308 is manufactured in the same manner as in the tenth to twelve degrees.

Alternatively, an insert head unit suitable for use in accordance with the present invention is constructed in the same manner as the sixteenth to nineteenth degrees, which is for firmly fixing various different electronic components.

In particular, the insertion head unit 308 includes a support block 316 and a vertical axis 314 mounted on the lower end of the vertical axis 314. The support block 316 has a push rod 340 provided through. The support block also has a fixed clamping member 318A mounted firmly on its lower end by a screw 348 so that it can be easily moved according to the size of the electronic component 334.

The support block 316 also has a set of guide members 350 and 352 provided on its outer side which are spaced apart from each other at regular intervals, between which the slider 354 can be inserted to slide horizontally. As shown in FIG. 18, the slider 354 is also manufactured to act as an air cylinder. In particular, the cylinder 354 has a cylinder chamber 356 formed therein, and the piston 358 housed in the chamber 356 is mounted to the support block 316. The piston 358 is formed to have an air passage 360 for supplying air to the cylinder chamber 356 therein. An expansion spring is disposed between the piston 358 and the slider 354 to return the slider to the left direction.

The slider 354 is formed integrally with the downwardly extending member 364 on which parallel links 366 and 368 are pivotally mounted by pins 370 and 372. The pins 374 and 376 pivotally mount or connect the movable clamping member 318b on the ends of the parallel links 366 and 368. In addition, an extension spring 378 for lowering the end of the link 366 to the link 366 is disposed between the link 366 and the pin 372. The link 366 has rollers 380 and 382 pivotally mounted thereon, and the stopper 384 is firmly mounted on the support frame 316.

In the insertion head unit of FIGS. 16 to 19 degrees, when the air cylinder in the slider 354 is not operated, the slider is connected to the stopper 384 when the air cylinder in the stopper 384 is not operated. It is arranged at the lower end by the extension spring 362 to rotate in the clockwise direction in contact with FIG.

In this state, the insertion head unit is moved from the electronic component supply device to the electronic component storage position, and the surface 336 of the fixed clamping member 318A is disposed opposite and close to the end face of the electronic component 334. Then, the air cylinder in the slider 354 is operated to move the slider 354 to the left. This causes the ends of the parallel links 366 and 368 to gradually descend due to the force of the tension springs 378, so that the rollers 382 can release the stopper 384 from contact with the links 366 as in the sixteenth and eighteenth degrees. When in contact with the lower surface of the support block 316, the movable clamping member 318B is brought to the same level or height as the fixed clamping member 318A. The support block 316 is formed with a groove 386 on the bottom surface thereof, so that the support block does not interfere with the movement of the roller 380.

Thereafter, further movement of the slider 354 in the right direction causes the workpiece clamping member 318B to approach the fixed clamping member 318A while keeping parallel to the member 318A, so that the electronic component is clamped therebetween. . At this time, since the opposing surfaces 336 of the clamping member 318 are kept in parallel with each other, the opposing surfaces are in planar contact with the electronic component so that they can be held firmly regardless of their dimensions. The roller 380 not only effectively prevents the upward turning caused by the reaction of the clamping action by the movable clamping member 318B, but also prevents the return of the clamping member 318B by contacting the lower surface of the support block 316.

Then, the insertion head unit 380 is moved to a position above the printed wiring board 104 and lowered to the plate for inserting the electronic component into the plate. Thereafter, air is removed from the air cylinder to return the slider to the left by the tension spring 362, so that the movable clamping member 318B is returned to the raised position of FIG.

Insertion head units suitable for use in the insertion apparatus of the present invention are manufactured in the same manner as 20 to 24 degrees. The insertion head unit shown in FIGS. 20 to 24 is for sucking up different types of electronic components, at least some of which are formed of a magnetic material using an electromagnetic force.

The insert device 500 includes an air cylinder 502 having a chuck 506 and a rod 504 connected to the lower end of the rod 504. The chuck 506 has an electromagnet formed by, for example, winding the coil 508 around a cylinder 510 formed of magnetic material.

At least a part of the electronic component 334 to be held by the insertion chuck unit 500 is formed of a magnetic material such as a transformer or choke coils, and is placed on a feed tray or a chute 512 as shown in FIG. Is placed on. The electronic component has a flat top surface, and thus the chuck 506 has a flat bottom surface. E and S represent DC power and switch, respectively.

Now, as described above, the operation of the configured insertion chuck device will be described.

First, the chuck 506 is moved to a position above the first electronic component 334 and the air cylinder 502 is designed to bring the lower surface of the chuck 506 into close contact with the upper surface of the component to lower the chuck onto the component. do. The switch S then closes to excite the coil 508 causing the chuck to suck the component due to the electromagnetic force. The air cylinder 502 then operates to cause the chuck 506 to move vertically as shown in FIG. Subsequently, the chuck 506 is moved to a position above the printed wiring board 104 and the air cylinder 502 is operated again to lower the chuck, so that the part is inserted into the predetermined position of the printed wiring board 104. The switch S is then opened to release the excitation of the coil 508 to release the excitation of the chuck 506 causing the chuck 506 to release the component 334 from there and the air cylinder to actuate the chuck. Return to the raised position.

The insertion chuck device may be changed as shown in FIGS. 25 to 27 degrees. In the modifications of FIGS. 25-27, the chuck 506 has an alignment traverse groove 514 formed thereon. Therefore, the transverse protrusion 516 is formed on the upper surface of the electronic component.

28 to 30 show another modification of the insertion chuck unit. In a variation, the chuck 506 is formed with self-aligning recesses 518 and pivotal alignment recesses 520 on the bottom surface. Accordingly, different types of electronic components 334, including components formed of magnetic materials such as transformers and choke coils, each have a centering protrusion 552 and a pivotal alignment protrusion 524 on its upper surface. Thus, when the electronic component is sucked onto the chuck 506, the components 334 are automatically centered and aligned with respect to the chuck 506 as shown in FIG. 30 by fitting projections 522 and 524 into the recesses 518 and 520, respectively. Let's do it.

31 to 33 show yet another modification of the insertion chuck unit. In particular, the insertion unit 500 shown in FIGS. 31 to 33 is a modification station 526 for correcting the change of the electronic component 334 held on the chuck 506 relative to the chuck before inserting the component into the printed circuit only. ). As shown in FIG. 32, the modification station 526 has a plurality of correction holes 17 formed corresponding to the leads 332 of the component 334. The crystal holes 528 each have an inclined hole or inlet 530. Thus, insertion of the lead 332 of the component 334 into the correction hole 528 causes the component 334 to slide transversely relative to the chuck 506 to remove the deformation W between the chuck and the component.

[Electronic component supply device]

The electronic component supply apparatus can be configured as shown in FIGS. 34 and 35 degrees. The supplies shown in FIGS. 34 and 35 are adapted to separately supply electronic components, in particular dual-in-line ICs housed in a magazine one by one. More specifically, the supply device 600 includes a frame 602 in which a plurality of magazines 604, each having electronic components or dual-in-line ICs 334, are housed superimposed on each other. Each of the magazines is arranged at an angle of about 45 degrees with respect to the horizontal plane. The magazine is formed in a cylindrical shape, made of plastic material, or the like, and houses electronic components superposed together in a predetermined manner in the longitudinal direction.

The supply device 600 is provided with an electronic component supply unit 606 configured to supply the electronic components separately one by one in the lower portion thereof.
