[0027] The working principle of the present utility model is as follows: Before drilling the PCB board, a feeding process is carried out. The PCB board is placed on the first feeding plate 52. Then, the feeding driving mechanism 51 is started. The first motor 512 drives the first lead screw 511 to rotate, thereby driving the first feeding plate 52 to move under the drilling assembly 4 for drilling operation.

Then, the first electric telescopic rod 532 is started to make the second feeding plate 533 reach the working position for drilling operation. After the drilling is completed, the first motor 512 is rotated in reverse again, so that the second feeding assembly 53 moves to the other side for discharging, and at the same time, the upper first feeding plate 52 moves under the drilling assembly 4 for drilling. This process is repeated. Through the feeding mechanism 5 that can alternate feeding, the waiting time during the feeding process is reduced, enabling continuous production and improving production efficiency. After the PCB board is placed on the first feeding plate 52 and the second feeding plate 533, the PCB board is positioned and clamped by the clamping device 6, and is pressed and fixed by the fixing component 7 to prevent movement during drilling, which may affect the drilling quality. The damper 74, spring 75, and rubber pad 77 provided on the fixing component 7 play a shock-absorbing role to prevent vibration during drilling from affecting the drilling quality.
