[0016] (1). The utility model is provided with a mounting block, a punching machine, a positioning laser lamp and a blanking port. A plurality of blanking ports are evenly arranged in the center of the set workbench. Side plate frames are symmetrically welded on the top surface of the set workbench, and a top plate frame is fixedly installed on the top surface of the side plate frames. A hydraulic cylinder is installed in the center of the top surface of the top plate frame. The output end of the set hydraulic cylinder is connected with a mounting plate. A guiding chute is arranged in the center of the bottom surface of the mounting plate. An adjusting lead screw is installed in the guiding chute. One end of the set adjusting lead screw is connected with the output end of a servo motor. A plurality of guiding sliders are evenly clamped and installed in the guiding chute.

At this time, the positioning laser lamp can be aligned with the blanking port. The positioning laser lamp is started to emit a vertical ray. Then the user sequentially places a plurality of circuit boards to be processed on the workbench, and aligns the punching points marked on the circuit board with the light emitted by the positioning laser lamp. At this time, the punching points can be ensured to be aligned with the blanking port. Then the user starts the servo motor again to drive the adjusting lead screw to rotate in the reverse direction, so that the mounting block drives the punching machine and the positioning laser lamp to reset.

A second anti-slip rubber pad is fixedly installed on one side of the clamping plate, which can improve the stability during the punching process of the circuit board and prevent the circuit board from being misaligned and affecting the processing quality. During processing, the user can start the hydraulic cylinder through the control panel to drive the mounting plate to move downward.

The bottom surface of the fixed block is provided with a telescopic rod, and the movable end of the telescopic rod is connected and installed on the top surface of the mounting plate. In addition, a spring is sleeved on the outside of the telescopic rod. As the mounting plate descends, the first anti-slip rubber pad fixedly installed on the bottom surface of the protective frame first abuts against the top surface of the circuit board, initially limiting and pressing the top surface of the circuit board to further improve its stability during processing. As the mounting plate continues to descend, the telescopic rod extends and the spring stretches. The punching device punches the punching point position on the circuit board. Due to the protection of the protective frame, the debris generated during punching can be prevented from splashing and hurting people, improving its use safety. The broken materials generated by punching can fall into the collection box placed in the inner cavity of the box through the blanking port for collection. Brief Description of the Drawings
