The present invention relates to a transfer jig of a print feeder that clamps a printed board (P. C. B) and then transfers the feed to an automatic component inserter.

As for the printed circuit board supplying device, which is filed by the applicant as a utility model registration application No. 91-7714, the rod of the lifting air cylinder 54 is fixed to the bottom of the rectangular body 50 as shown in the third drawing, and the air cylinder is provided inside the body 50. The 51 is installed to move horizontally, the movement between the rectangular movement (1) protruding out of the body 50 to the air cylinder 51 is fixed, the L-shaped bending piece (3) in the long groove (2) of the movement A large number of fixed positions can be arbitrarily changed, and the plate clamp 52 and the circular clamp 53 are alternately fixed downwardly in the long hole 5 of the bent piece 3 so that the tongs 52 and 53 are raised and lowered horizontally. When the printed circuit board 9 is supplied to the guide rail, the tongs 52 and 53 are lowered by the lowering of the air cylinder 54, and the two sides of the printed board 9 are gripped by the air cylinder. 51 is advanced horizontally, and tongs 52 and 53 feed and feed the printed board 9 to the insertion machine (automatic part inserter). When the feed supply of the substrate 9 is completed, the tongs 52 and 53 are raised by the rise of the air cylinder 54, and the tongs 52 and 53 are reversed by the horizontal air cylinder 51 to print back. The transfer of the substrate 9 is completed, and the next printed substrate can be repeatedly transferred.

The conventional printed circuit board supplying device has a relatively large sized gap between the tongs 52, 53 and the printed board 9 because the tongs 52 and 53 are configured to grip and transfer both sides of the printed board 9. (Approximately 2mm) occurs and the printed board 9 is not completely transferred to the inserter, so there are frequent cases in which clamping for automatic insertion of parts in the inserter is not performed properly, causing delays in work, and a small quantity Since the size of the printed board is also frequently changed according to the tendency, the position and spacing of the plate clamp 52 and the cone clamp 53 must be appropriately modified, but the time required for correcting the position and spacing is excessive, and there are many factors that reduce productivity. Since tongs 52 and 53 are used, there is a problem that weights and vibrations are generated during reciprocation of the movement 1.

The present invention aims to allow the transfer jig to insert and then feed the one side through-hole formed in the edge of the printed board in order to solve the conventional problems of the printed circuit board supply apparatus as described above.

In order to achieve the above object, the utility model registration application No. 91-7714 of Applicant deletes conical tongs and L-shaped bent pieces to fix them, and is fitted to one side hole formed at the edge of the printed board instead of plate tongs. It can be fixed to the support bar to transfer the supply of the printed board, the support bar is elastically installed by the spring to the L-shaped bending piece to prevent the damage of the printed board by the impact when the poor insertion, the preferred embodiment of the present invention An example will be described in detail with reference to the accompanying drawings.

In the printed circuit board supplying apparatus, in which the L-shaped bending piece 3 can be changed in a fixed position in the long groove 2 of the moving member 1 which moves up and down and moves horizontally by the air cylinders 51 and 54, After contacting the support piece 6 to the resistance guide groove 20, the chapter 19 is lowered.

The inserting portion 11 of the descending transfer jig 19 is clamped by being loosely inserted into one side through-hole 10 of the printed circuit board 9 and the horizontal air cylinder 51 installed in the body 50 when the clamping of the printed board is completed. ) Is moved forward to move the movement 1 in the direction of the arrow (A direction), so the clamped printed board 9 is also fed in the direction of the arrow along the conveying rail 21 and supplied to the magnetic inserter.

When the printed board 9 is transferred to the inserter, the vertical air cylinder 54 is raised to separate the inserting portion 11 of the transfer jig 19 from the through hole 10 of the printed board, and the printed board 9 is inserted into the insert. It is clamped to the machine to allow automatic part insertion.

When the transfer jig 19 is lifted apart from the printed circuit board 9, the horizontal air cylinder 51 is moved backwards, and the moving period 1 and the horizontal air cylinder 51 are moved backward to move the moving period 1 and the transfer jig 19. ) Is moved in the opposite direction to the arrow (A), and the self-inserting machine clamps the fed substrate to be fed as usual, and then automatically inserts the parts.

After the automatic insertion of parts of the inserting machine is completed, the transfer jig 19 returned to the original position receives another printed board 9 supplied on the guide rail 21 by the lowering of the vertical air cylinder 54. Repeatedly feed the inserter.

In the present invention, since the inserting portion 11 of the transfer jig 19 clamps and feeds the through hole 10 of the printed board, the play of 2-3 mm by the tongs 52 and 53 does not occur as in the prior art. Since the feed is carried precisely to the clamping position of the jig (not shown), work delay factors caused by bad clamping are eliminated.

In addition, even when the transfer jig 19 clamps and transfers one side through-hole 10 located near the edge of the printed board 9, the printed board 9 is transferred in parallel by the protruding jaw 22 of the guide rail 21. Since the support rod 12 is elastically supported by the shock absorbing spring 15, even when the inserting portion 11 of the transfer jig 19 which descends during clamping is slightly out of the through hole 10 of the printed circuit board, 9) breakage is prevented.

In addition, since only one transport jig 19 is used to transport the printed board 9, vibration and noise are reduced during the reciprocation of the movement 10.

On the other hand, when the size of the printed circuit board 9 is changed, the support piece is relaxed so that the insertion part 11 of the transfer jig can be inserted into the through hole 10 of the printed circuit board 9 by loosening the bolt 7 fixing the support piece 6. Since the loosening bolts 7 are tightened after adjusting the protruding length of (6), the positional modification of the transfer jig 19 is easy.

In addition, when the size of the through hole 10 of the printed circuit board 9 is changed, the support rod 12 having a diameter smaller than the diameter of the through hole 10 may be replaced.

As described above, the present invention is precisely conveyed because the inserting part of the transfer jig clamps the through hole of the printed board, so that no separate plate clamp is required, thereby reducing material and greatly reducing vertical and horizontal vibrations during up and down flow between movements. .

In addition, when the size of the printed board is changed, it is easy to modify by adjusting the protruding length of the support piece, so that the modification is easy and the modification time is shortened, thereby improving productivity.
