Contents of the invention

In order to make up for the deficiencies of the prior art, an automatic PCB board shearing machine and its control circuit described in the present invention can realize fully automatic horizontal cutting and vertical cutting of PCB boards without manual operation.

The technical solution adopted by the present invention to solve the technical problem is: a PCB board automatic shearing machine, which has a cross-cutting unit for horizontally cutting the PCB board, a vertical cutting unit for vertically cutting the PCB board, and an accommodating cross-cutting unit The body with the vertical cutting unit and provides the movement space of the PCB board, the bottom resistance device for the bottom limit of the PCB board, and the top resistance device for the top limit of the PCB board;

The body is provided with a slide plate groove for the PCB board to slide down step by step from left to right; thus, the PCB board of the present invention does not need to be pushed by hand during the cutting process, and only needs to rely on the gravity of the PCB board itself to move downward. For its own horizontal and vertical cutting, the manual push is changed to automatic drop. Compared with the traditional shearing machine, the shearing efficiency is improved, and the hand injury caused by accidentally touching the cutting tool of the shearing machine is avoided. Injury situation.

Specifically, a cross-cutting tool is installed on the cross-cutting unit, and the cross-cutting tool is located on the upper part of the machine body and performs cutting movement along the direction parallel to the slide plate groove. The cutter can cut the PCB board horizontally along the left and right direction of the PCB board.

Specifically, the cross-cutting tool can do overall translation along the direction perpendicular to the slide plate groove, so that the cross-cutting unit can control the up and down height of the cut PCB board. Transverse cutting is not carried out in the slide plate groove, and when the heights of the PCB boards that need to be cut from the middle of the PCB board are different, the position of the cross-cutting tool in the slide plate groove can be adjusted; thus the present invention can adapt to the cutting operation of PCB boards of different heights.

Specifically, the vertical cutting tool can perform overall translation along the direction perpendicular to the sliding plate groove, so that when the PCB board needs to continue sliding from the vertical cutting unit to the bottom of the machine body, or when the PCB board does not need to be vertically cut, only the The vertical cutting tool moves to the range of breaking away from the slide plate groove.

Specifically, the bottom resistance device is located on the body on the right side of the vertical cutting unit, and limits the lower end of the PCB board within the cutting range of the vertical cutting unit, so that the vertical cutting tool can cut so that the vertical cutting unit and the bottom resistance device The PCB board in the area between is separated from the PCB board in the body as a whole.

Specifically, the bottom resistance device can perform overall translation along the direction parallel to the slide plate groove, so that the present invention can adjust the distance between the bottom resistance device and the vertical cutting tool, and then can adjust the left and right width of the cut PCB board, When the bottom resistance device slides down parallel to the direction of the slide plate groove, the distance between the bottom resistance device and the vertical cutting tool increases, and the left and right width of the cut PCB board increases. On the contrary, the left and right width of the cut PCB board increases. The width is reduced, so that the present invention can automatically cut PCB boards of different and arbitrary sizes, and has a wide range of applications.

Specifically, the bottom resistance device can be shrunk into the body so that the outer end surface of the bottom resistance device is flush with the inner end surface of the slide plate groove.
