Since the L-shaped rubber plate 25 is fixedly connected to the inner cavity of the L-shaped block 24, the L-shaped rubber plate 25 can reduce the damage caused by the L-shaped block 24 to the PCB circuit board, and thus the yield rate can be improved, so as to improve the production efficiency.

[0035] By means of the pneumatic telescopic rod 31 in the drilling component 3, it can be fixedly connected to the central position of the top surface of the C-shaped frame 14 and provide an installation basis for the connecting plate 32. Since the servo motor 33 is fixedly connected to the bottom surface of the connecting plate 32, and the drill bit 34 is rotatably connected to the output end of the servo motor 33, the output end of the pneumatic telescopic rod 31 can drive the connecting plate 32 to move up and down while telescoping, and then the connecting plate 32 can drive the servo motor 33 to move up and down, so as to enable the servo motor 33 to drive the drill bit 34 to move up and down. Then, through the servo motor 33, the output end of the servo motor 33 can drive the drill bit 34 to rotate, and thus the drill bit 34 can perform drilling on the PCB circuit board, so as to improve the work efficiency.
