The present invention relates to a guide frame driving device of the automatic PCB inserter, and in particular, the guide frames on both sides can be adjusted to the left and right by using the width adjustment handles according to the right and left size of the PCB. The present invention relates to a guide frame driving device that supports a PCB loaded on a table without shaking to be put into a post-stage process.

In general, the automatic PCB inserter used in the PCB (Printed Circuit Board) manufacturing process automatically and uniformly performs a certain size of PCBs loaded on the table continuously in the post-sequence process for a certain period of time according to the up and down and back and forth operation of the vacuum pad. As a device for supplying, a plurality of PCBs 31 are placed on a table 30 driven up and down as shown in FIG. 1A, and then the table 30 is moved up and down and back and forth by the vacuum pad 32. ) PCB 31 is adsorbed one by one and is repeatedly operated to continuously supply it to the post-stage process. However, when the vacuum pad 32 absorbs a single PCB 31 of a plurality of PCBs 31 uniformly loaded on the table 30 and transfers the same to the rear end process by vertically and vertically acting, Even though the PCBs 31 are well aligned and placed on the table 30, the vacuum pad 32 may be vacuumed and generate static electricity as shown in FIG. 1B during PCB transfer of the vacuum pad 32. Due to the phenomenon that the remaining stacked PCB 31 is disturbed, it is difficult to supply the correct rear end according to the up and down and back and forth operation of the vacuum pad 32 in the PCB transfer process.

Therefore, in the manufacturing process of the PCB, the unmanned operation of the PCB input process is not made, and the operator is put in, and the transfer process of the PCB is performed, and then the artificially disturbed PCBs 31 are loaded after the transfer on the table 30 of the automatic PCB inserter. The condition should be checked from time to time so that the operation of the vacuum pad 32 is aligned in an orderly manner.

If the PCB transfer process is performed as described above in a non-uniform PCB loading state on the table 30 as shown in Figure 1b, the vacuum pad 32 according to the up and down operation is a hole (Pole) of the sheet PCB 31 By absorbing the part or by absorbing the outside of the sheet PCB 31, it is impossible to accurately collect the sheet PCB 31 on the table 30 during the PCB transfer process of the next vacuum pad 32, so that the unmanned work cannot be performed. There was a flaw.

The present invention has been devised to solve the above-mentioned drawbacks, and the left and right sides of the PCB to be loaded on the table by installing a guide frame to align the stacked PCB on the table in a line so that the unmanned work of the PCB input process is performed. The width of the guide frame can be adjusted by the width adjustment handles according to the size, and the PCB to be unevenly loaded by the guide frame already set during the PCB transfer process of the vacuum pad is forcibly arranged so that the single PCB is continuously put into the post process. It is an object of the present invention to provide a guide frame driving device for an automatic PCB inserter that supports PCBs loaded on a table without being disturbed.

The guide frame driving apparatus of the present invention for achieving the above object, a single PCB 31 by the vertical and vertical operation of the vacuum pad 32 to load a plurality of PCB 31 on the table 30 driven up and down In the automatic PCB feeder that is continuously supplied to the post-stage process by adsorption, the left and right guide frames (33, 34) and the guide bar to align the plurality of PCB (31) stacked on the table 30 in a line ( 8) the screw housings 5 and 9 so that the lead screws 6 and 9 connected to the bevel gear 16 are rotated so that the guide frames 33 and 34 are moved left and right according to the left and right sizes of the PCB 31. 10) characterized in that consisting of a width adjustment handle (18) to be delivered to.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a guide frame driving apparatus according to the embodiment of the present invention is installed in the automatic PCB inserter, the guide frame driving apparatus of the present invention is a table (30) waiting for the PCB 31 to be correctly injected into the back-end process (30) The guide pads 33 and 34 on both sides of the plurality of PCBs 31 loaded on the operation of the width adjusting handle 18 so that the vacuum pad 32 can accurately pick up the hole-free area on the PCB 31. ) Is fixed to the set position, and as the automatic PCB feeder is operated by the switch operation of the front panel, as shown in FIG. By adsorbing the site, the PCB 31 is precisely put into the post-stage process by back and forth operation. In the upper and lower and front and rear operation processes of the vacuum pad 32, even if the rest is shaken due to the generation of vacuum and static electricity of the PCB 31 itself, the guide frames 33 and 34 on the left and right sides installed next to the table 30. By being forced to be aligned by, the alignment state of the remaining PCB 31 is stabilized between the guide frame (33, 34) as shown in Figure 3b and continuously of the remaining PCB 31 The vacuum pad 32 is absorbed by the up-and-down and back-and-back operation of a specific part without a hole. Accordingly, the loading PCB 31 forcedly aligned between the guide frames 33 and 34 adjusted by the width adjusting handle 18 as shown in FIG. 3B by the vertical and horizontal operations of the vacuum pad 32. By adsorbing exactly one sheet, it can be continuously supplied to the post-stage process.

On the other hand, according to the left and right size of the PCB 31 mounted on the table 30 is adjusted by the width adjusting handle 18 to adjust the width between the guide frame (33, 34), which shows the AA line in detail As shown in FIG. 4, the guide frames 33 and 34 to be installed between the supporting members 3 and 11 are horizontally transferred by clockwise or counterclockwise rotation of the width adjusting handle 18, and the PCBs are stacked in a row. (31) straighten both sides.

That is, between the support members 3 and 11 of the AA shown in FIG. 2 and the width adjusting handle 18, both brackets 1 shown in FIG. 4 are fixed to the support members 3 and 11. Guide brackets 2 are provided on these brackets 1, respectively.
