Then the clamping plate will first contact the surface of the PCB board. Then, as the lifting plate continues to descend, the clamping plate will be squeezed against the spring through the cooperation of the sliding plate. Then, under the elasticity of the spring, the clamping plate will clamp and fix the surface of the PCB board, so that the PCB board will not slide. Then, after the drill bit completes drilling, the lifting plate returns to the original position. At this time, the clamping of the clamping plate to the PCB board is cancelled. Repeat the above process. The unloading device for the PCB drilling machine can clamp and fix the PCB board directly during drilling, thereby improving the drilling efficiency of the unloading device for the PCB drilling machine.
