Description

[Detailed Description of the Invention] V-Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a device for inserting various electronic components into a printed circuit board, and is particularly suitable for inserting irregularly shaped components such as coils and connectors. The present invention relates to a suitable electronic component insertion device.

[Conventional technology]

As for the conventional device, a modular device is provided as described in Japanese Patent Laid-Open No. 57-199296. However,
The above-mentioned component has many leads, and there are many lead bends and lead position deviations, and the method of simply grasping the body of the component and inserting it causes many insertion errors. Disadvantage] The above conventional technology does not take into account the positioning of the board holes and leads for parts with leads that are flexible and easy to bend, or for parts where the positional force of the leads is misaligned from the external shape of the part. There was a problem that insertion failure occurred. In addition, when an insertion failure occurred, the machine had to be stopped and the operator had to restart it, making full automatic operation impossible. Furthermore, for parts installation, the head and the shaft and connecting frame for moving the anvil head to the entire board insertion range are required.
Because of the movement, the work area became larger and the installation area of the equipment became larger.

An object of the present invention is to solve the above-mentioned drawbacks of the prior art and to provide a device with high insertion reliability, small size, and high productivity.

[Means for solving problems]

In order to improve the above-mentioned insertion reliability, the component supply section straightens the leads, aligns the lead tip positions, and, if necessary, makes a V cut at the lead tip (to improve alignment with the board hole. For parts that are inserted by gripping the body, when gripping the part body with the insertion head chuck,
Grips based on the lead standard and absorbs misalignment between the part body and the lead position.

For parts such as DIPIC where the lead is outside the part body, the lead tip is guided through a Y-shaped groove to determine its position. If the insertion is incorrect, remove the incorrectly inserted parts and perform the critical operation again. For this reason, a defective insertion is detected during the component insertion process, and the grip on the component is released (the defective component is ejected to the ejection station. Then, the defective component is reinserted again with a new component. This prevents damage to parts without applying more load than necessary.In order to reduce the size of the device, the insertion head and clinch are configured so that they can be guided by guide rails and moved.The following.

The above objective is achieved by the above.

[Effect]

For parts that are inserted by grasping the body of the part, in order to absorb errors in the external shape of the part and lead position, the lead is positioned and fixed at the part delivery part to the insertion head of the part supply part, and in that state, The insertion head is lowered to grip the component body, and at this time the chuck of the insertion head is floated with a thrust type air bearing structure. Grip the body of the part with the floating chuck. Then, the chuck is shifted by the amount of deviation between the component outline and the lead position. After that, the floating state of the chuck is stopped and the chuck is fixed.

This allows the component to be gripped based on the lead.

Thereafter, the fixation of the lead is released, and the insertion head rises to move onto the printed circuit board and insert it.

As described above, it is possible to absorb misalignment between the external shape of the component and the position of the lead. In addition, parts such as DIPIC with flexible leads formed outside the part body,
The bends in the leads were formed at the regular pitch between the leads (spread the leads with a wedge-shaped correction mold to align the pitch and span directions.Next, cut the lead tips to make them easier to fit into the board holes.Correction like this , ■The parts that were cut,
Grip the lead with the chuck on the insertion head. At this time, a Y-shaped groove is formed in the chuck, and the lead is guided and positioned along this groove. At this time, the flexible lead can be accurately positioned in the chuck groove by guiding it into the chuck groove from the axial direction of the lead tip, where the lead is difficult to bend.

Insertion defects can be detected by lowering the insertion head toward the board for parts that are inserted by chucking the part body. If the insertion is defective, the lead will hit the board surface and the chuck will stop descending. and.

The relative position of the insertion head is detected and determined. Furthermore, for parts that chuck leads, the insertion height of the part is detected and determined after insertion.

Furthermore, to make the device more compact, the insertion head and clinch are guided on the X-axis table by a guide rail.

A Y-axis frame was installed, which allowed only the insertion head and clinch to be moved.

Similarly, air pressure intake ports 380, air passages 381, and nozzles 382 are formed at appropriate locations on the upper plate 376. Furthermore, air pressure exhaust ports 383 are formed at appropriate locations in the intermediate plate 375. When compressed air flows in from the air pressure intake ports 377 and 380 from such a configuration, it becomes an air thrust bearing, and the entire chuck component attached to the 7 flange 373 floats. 7
Lunge 373 has a hole 384 and lower plate 374
A bottle 385 embedded in is engaged. This restricts unnecessary plane movement of the chuck component. Top plate 376 is fixed to rotating block 308'.

A crank 386 is formed in the rotating block 30B'. When the piston 387 is operated, the 7 lunge 375 is pressed. The rotating block 308' is capable of two rotations of vertical movement similar to the insertion head E in the vertical block 313'.

Clinch F is shown in FIGS. 50 to 53. The clinch claw 400 is rotatably attached to a clinch house 401 with a lever 403 rotatably attached to a pin 402. A tone spring 404 is inserted through the pin 402 through the clinch claw 400 and the lever 403, thereby biasing the clinch claws 400 and 400' in the mutually closing direction. Also, the lever 403 has a limit switch 405.
The installation is shaking. A pin 406 is fixed to the clinch pawl and fits into a hole 407 provided in the lever 403.

The lever 403 has a roller 409 rotatably attached to the bin 408.
is fixed. Furthermore, the lever has a tension spring 410.
is applied to bring the roller 409 into contact with the piston 411.

Clinch house 401 is fixed to rotating block 435. A cylinder 412 is formed in the rotation block 412, and a lid 413 is fixed to the lower part of the S rotation block 435. A compression spring 414 is also provided inside.

A compression spring 414 is also provided inside. The rotation block 435 is rotatably attached to the upper and lower blocks 415. A binion 416 is fixed to the lid 413 and engages with a rack 417. The rack 417 is guided by a U-shaped groove 418 in the upper and lower blocks 415 and is slidable therein.

An L fitting 419 is fixed to the rack 417, and an L fitting 41 is fixed to the rack 417.
9 is a bracket 420 fixed to the upper and lower blocks 415;
The rod 422 of the cylinder 421 which is attached to the cylinder 421 is loosely engaged with the bolt 423 at the tip of the rod 422. Because of this configuration,
When the cylinder 412 is operated and the piston 411 is raised, the clinch claws 400, 400' are closed. The piston is raised using the stopper screw 4 attached to the clinch house 401.
24, and as a result, the amount of closing of the clinch claws can be varied. The clinch house 401 also has an adjustable supporter 425 to support the downward curvature of the supporter 60.

When the cylinder 421 is operated, the rack 417 is operated,
As the pinion 416 rotates, the tally reach pawl 4
00, 400' can be rotated at 0', 90'.

The upper and lower blocks 415 are slidably assembled together by a guide bar 427 fixed to an upper and lower guide block 426. There is a cylinder 428 in the upper and lower blocks 415, and the piston 4
29. A lid 430 is fixed to the top of the cylinder 428. The piston 429 is connected to the vertical guide block 4
It is fixed at 26. Therefore, when the cylinder 428 is operated, the vertical block 415 moves up and down, and as a result, the clinch claw 400 rises to the lower surface of the substrate 30, bends the lead 51, and then descends.

An adjustment screw 436 is attached to the lever 403 and is in contact with the clinch house 401. This is clinch nail 4 from K.
Adjust the opening amount of 00.

When bending the lead 51, the piston 411 is raised and the clinch claw 400 is closed (and the clinch claw 4 is attached to the lead 51).
00 comes into contact. When the piston 411 is further raised and tightened, the clinch claw 400 moves toward the open position due to the bending resistance of the lead 51. At this time, the clinch claw 400 separates from the limit switch 405, and the switch state changes. The piston 411 is further advanced. and pin 40 in hole 407.
6 is restricted from moving, and now the clinch claw 400 moves in the closing direction and bends the lead 51. If part 5
When 0 is inserted incorrectly, there is no lead, so the clinch claw 400 does not move in the open direction, so the state of the limit switch 405 does not change.

This makes it possible to detect insertion length and defects.

From the above, the force with which the talk spring 404 presses the clinch claw 400 is set to be weaker than the bending resistance of the lead 51.

The Y-direction positioning unit) C is shown in FIGS. 54 to 57. A Y frame 200 is placed and fixed on the X table 150 of the X direction positioning unit B. Bearings 201, 202, 203 are included in the Y frame 200.

, 203, 204°. 223, 224J225, 226 are timing pulleys, 227, 228 are timing belts, and by these transmission mechanisms, the Y direction feed screw 205
, 206 rotate synchronously.

When the X motor 229 rotates, the timing pulley 226
rotates, and the timing pulley 225 fixed to the Y-direction feed screw 205 rotates via the timing belt 228. This rotation is carried out via the timing pulley 223, timing belt 227, and timing pulley 224.
The signal is transmitted to the direction feed screw 206 and the Y direction feed screw 205
, 206 rotate synchronously.

Note that the X motor 229 is fixed to a plate 230 attached to the Y frame 200.

X direction positioning unit)B is as shown in Fig.
The table 150 is slidably fitted to the X-direction guide rails 153 and 154 by nuts 151 and 152.

For sliding in the X direction, an X direction feed screw 155 is rotated by an X motor 156 in FIGS. 1 and 54.

This is done by an X table 150 that fits into the X direction guide rails 153 and 154. In this case, it moves together with the Y-direction positioning unit E.

As mentioned above, the X, Y of the insertion head E1 and the clinch F
When moving in this direction, all of these weights move while being stably supported by the X-direction guide rails 153, 154, and the Y-direction guide rails 211, 212, 216, and 217.

Further, when the insertion head E1 and the clinch F are moved in the Y direction, only the insertion head E and the clinch F move, and they can be moved quickly by reducing the moving weight.

The substrate transport rail D has a belt for feeding the substrate and a substrate guide pin mechanism for fixing one substrate in a fixed position. Details are omitted.

Next, the operation will be explained. First, like the IC shown in FIGS. 4 and 19, a component 50 (for example, a dual inline parts cage IC) has leads 51 formed on the outside.
) from supply to insertion.

The parts 50 are stored in a magazine 54, and several magazines are stored in a cassette case 6o1. This cassette case is set in the predetermined section of the parts storage section H. The operation of the cylinders 623, 624 unloads the magazine 54, and when the lowest end, ie the part 50, is in a position to flow onto the rail 727 and be fed, the part is slid on the rail 727 and fed. When the parts 50 are sequentially supplied and there are no more parts 50 in the magazine, the cylinders 619 and 620 are driven by detection by a sensor (not shown) to discharge the empty magazine, and then the cylinders 625 and 624 are driven.
The magazine 54 is driven to drop the next magazine 54 to the bottom end. At this time, the cylinders 619 and 620 have returned to their holes, so the magazine 54 is received by the L fittings 607 and 608.

As described above, the empty magazine 50 is automatically ejected. On the other hand, the component 50 slidably supplied on the rail 727 is supplied to the lead correction section J. The component 50 that has been completely corrected as described above slides onto the rotating block 521 of the component supply section G. Cylinder 526 is then actuated to convert component 50 to a horizontal position. Then the cylinders 506', 5
By the operation of 38, the images are conveyed sequentially. Next, the component 50 is transported to the lead tip cutting section K. Then, as described above, the tips of the four leads 51 are cut. Next, the parts are further conveyed and positioned at the parts delivery section. Next, the component is gripped by the chuck of the insertion head E. The insertion head E is
By the operation of the Y positioning units B and C, the component 50 is moved and stopped above the component delivery section. This much I! In a relationship? Component delivery will now be explained with reference to FIGS. 58 to 60. V-shaped grooves 348 are formed in the chuck 300 for the number of 510 lead wires (for one row of the dual in-line package ICO). FIG. 60 (α) shows the initial positional relationship when chucking the component 50. Next, as shown in FIG. 60 (1), the upper and lower blocks 613 of the insertion head E are lowered, and the chuck 300 and pusher block 342 are lowered. Next, as shown in FIG. 60(e) K, close the chuck. Next, as shown in FIG. 60(d), the pusher block 342 is lowered to lower the component 50, and at this time, the lead 51 is guided by the groove 348.
Positioned. At this time, the positioning rail 901 is also simultaneously lowered until it comes into contact with the stopper screw 904. When the lead 51 is chucked in the above manner, the chuck 500 rises while chucking the part 5o, as shown in FIG. 60Ce), and the chuck is completed. When the component 50 is raised, the vacuum suction by the hose 907 is stopped. lead 5
As shown in FIG. 59, the lead 1 is expanded outward in a V-shape in the lead correction section J in advance, and is supported by the reaction force of the lead 51 when the chuck 300 grips the lead 51. The insertion head E, which has chucked the component 50, is moved to the insertion position of the board 30 by the X motor 156. Drive the Y motor 229,
Moving.

After stopping, the insertion operation begins.

In the insertion operation, air pressure is applied from the arrow 320 in FIG.

The tip of the chuck 300 descends to the upper surface of the substrate 30 and stops. When the lead 51 enters the board hole 31 normally (No.

Figure 61 (α)) 9 Next, as shown in Figure 61 (C), there is chaff.

300 and then move the button cylinder 328.

The pusher block 342 inserts the component 50 into position. However, in the phrase shown in Figure 61 (1)),
If the lead 51 and the board hole position do not match, resulting in poor insertion, immediately stop the descent of the pusher block 342, stop the insertion operation, raise the chuck 300, raise the component 50, and move the X-Y positioning unit). By operating B and C, the component 50 is discharged to a discharge station (not shown), the component is again grasped from the component delivery section, and the reinsertion operation is performed. The insertion failure is caused by the printed circuit board 30 as shown in Fig. 61 ('b).
If the lead 51 is not inserted into the hole 61, the chuck 300
The lead 51 protruding from the tip of the lead 51 hits the upper surface of the substrate 30 and is returned, resulting in a step t between the normal state shown in FIG. 61 (α) and the height of the component. Push this step t
The detection is performed by the operation of the switch 342.

The insertion layer defect detection method is as explained in Fig. 61.
Since there is a step t in the height of the component between the insertion layer (α) and the insertion failure ('b), there is a time difference between when the pusher block 342 reaches that position and the gap L (FIG. 41) is reduced. If this time is determined in advance for the insertion layer and the pattern at the time of insertion failure and is inputted as a parameter into the detection control system, it becomes possible to detect the insertion layer and the failure using the control flow shown in FIG. 62. A proximity sensor 343 detects whether the tip 336 hits the block opening 30 or not. The flow shown in FIG. 62 will be explained. The chuck 300 is lowered. chuck 3
00 reaches the board surface and stops, pusher block 3
Descend 42. Thereafter, if the proximity sensor turns ON, it is determined that the insertion is defective, and if the proximity sensor does not turn ON within the set time, it is determined that the insertion layer is present. When inserting layer, block 3
30 descends and hits the flap 336, thereby obtaining the pressing force necessary for insertion.

Next, the timing diagram shown in FIG. 66 will be explained.

When the cylinder 328 is lowered and the proximity sensor 343 is turned on within seconds from that point, it means that the insertion is defective, so issue a command as shown by arrow m to stop the cylinder 328 from lowering and raise it (as shown by the dotted line). ).

If the proximity sensor 343 does not turn on for t seconds, the insertion length has been reached, and the cylinder 328 continues to descend to the home position. Therefore, the proximity sensor 34
3 is finally turned on.

After the insertion is completed, the clinch claw 400 of the clinch F is operated to bend the lead 51 and temporarily fix it to the board 30 as shown in FIG. 61(d).

Next, the insertion of a component such as a component 57 shown in FIG. 30, in which the lead 56 is extended from the lower surface of the component body, will be explained.

The lead 56 is supplied from the component storage section A, and is supplied to the component delivery section L' by the component supply section L' to fix the lead 56. The above is as described above. The parts in the parts delivery section L' are waiting to be delivered to the insertion head E'. The insertion head is moved and stopped above the component 57 in the component delivery section by the operation of the X, Y positioning units ", σ".The lead 56 of the component 57
is positioned and fixed against a stopper 929. The chuck 350 is lowered in this positional relationship (FIG. 64). At this point, the chuck 350 has stopped the 70-ting state, and the flange 373 is pressed and fixed by operating the piston 387. The chuck component is therefore fixed. Once again, the cylinder 369 is operated, and the tip rod 370 presses the collar of the chuck holder 357. The piston 387 is then raised at the lower end, and then air pressure is introduced from 377 and 380 to float the 7-lunge 373, thus bringing the chuck component into the 70-ting condition. Next, the piston 359 is lowered in the 70-ting state, the chuck 350 is closed, and the component 57 is gripped.

Next, when the gripping is completed, the flow rung state is stopped, and the piston 387 is lowered again to fix the chuck component. Next, the cylinder 924 of the parts delivery section L' is operated to move the piston 930 backward. Then, the clamp plate 922 moves back due to the action of the compression spring 927, releasing the fixation of the lead 56. Then, with the part 57 gripped, the chuck 35
0 rises to the top.

Next, operate the X-Y positioning units) B and C to move the board to the insertion position and stop. Next, lower the chuck and
Just before the tip of the lead 56 reaches the top surface of the board, the cylinder 3
69 to retract the tip rod 370. This prevents an excessive load from being placed on the lead 56 even if there is an insertion failure.

Compression spring 368 is therefore intended to offset the weight of components attached to chuck holder 357.

The insertion length and defects are detected by the proximity sensor 371. That is, at the insertion length, the gap L between the chuck box 363 and the chuck holder 357 does not change. In case of poor insertion, the lowering of the chuck holder 357 stops because the lead 56 gets caught on the upper surface of the substrate or inside the hole, so only the chuck box 363 lowers, and the gap L is thereby reduced. If the proximity sensor 371 detects at this timing, the insertion length and defect can be detected. At the insertion length, the cylinder 369 is operated to hold down the chuck holder and prevent the parts from floating during the talin reach. After clinching, the chuck 350 is opened, the parts are released and raised, and the insertion is completed. If the insertion is incorrect, the chuck 350 is immediately raised,
As with insertion head E, defective parts are removed.

Eject it to the exit station and reinsert it again with another part 5
゜Here, the floating of the chuck will be explained with reference to Figs. 65 to 67. A component, such as lead 56', is deviated by δ from the position where lead 56 should be due to a manufacturing error of component 57.

In contrast, the part body is chucked based on the lead.

This absorbs component manufacturing errors and provides a high insertion success rate. It is constructed by combining the center of the insertion spatula 9D and the lead positioning center Z of the component delivery section L'. When fixed based on the lead at the component delivery section L', the component is shifted from Z by an amount of δ. , by floating, shifts the center of the chuck 350 by δ.This is the part 57
When chucking the part 57', the chuck 350 chucks the part 57'.
It is done by sandwiching the two together. If the floating chuck 350 is fixed in this state, the insertion head E
The part 56 can be gripped by aligning the center of the lead 56 with the center of the lead 56. The insertion of a component having the lead 56 on the lower surface of the component body, such as the component 57, has been described above, but for this-shaped component as well, the lead is tightened and the lead tip is cut, if necessary.

〔Effect of the invention〕

According to the present invention, a multi-lead component can be inserted with a high insertion success rate, and the component will not be damaged in the event of an insertion failure. In addition, it is possible to create an insertion machine that can perform automatic reinsertion and has high productivity. Furthermore, the X and Y positioning units are small and space-efficient (can be used in stand-alone type 0 or connected type), and can be used for production of a wide variety of products in small quantities.
It has great effects when used widely, even in mass production.
