At this time, the clamping plate 304 is against the inner wall of one side of the bottom of the frame 1. The circuit board to be punched is placed between the two clamping plates 304, and then the clamping assembly 3 is started again. At this time, the electric rod 1 303 also extends, and then the clamping plates 304 on its shaft ends are clamped on both sides of the circuit board through the silicone pads 304a. At the same time, the above-mentioned two pneumatic rods 302 work in the opposite direction to deliver the two clamping plates 304 holding the circuit board to the bottom of the drilling assembly 4.

At this time, because the length of the elastic rod 406 is greater than the length of the punch 407, the feedback member 408 will first contact the circuit board, and then the pressure sensor 408b therein will receive the contact pressure, that is, it is determined that the punch 407 is about to contact the circuit board, and then the extension speed of the hydraulic rod 405 is reduced by adjusting the controller, so that the punch 407 on the shaft end slowly contacts the circuit board, and the bottom ring 408a on the feedback member 408 contacts the outer wall of the circuit board through the rubber ring 408c, and the punching area is abutted to ensure that the punching work can be carried out stably.
