Therefore, a circuit board punching anti-crack device is often used in the process of circuit board processing.
[0003] However, existing anti-cracking devices for punching have weak fixing functions. During the production process, circuit boards need to be processed into different specifications according to different application fields. Then, punching is required for circuit boards of different specifications. During the punching process, existing anti-cracking devices for punching have difficulty fixing circuit boards of different specifications, which leads to displacement of the circuit boards during punching and causes them to crack. Not only that, existing anti-cracking devices for punching have poor punching effect. When using them, punching is required at different positions on the circuit board according to the application scenario. However, existing anti-cracking devices for punching have difficulty adjusting the punching position, resulting in poor punching effect. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This circuit board punching anti-crack device, through the arrangement of an adjusting frame, sliding blocks, hollow columns, and fixed columns, allows the circuit board to be punched to be placed on a support plate between a support frame and an adjusting frame during use. The sliding blocks are then used to adjust the position of the hollow columns on the adjusting frame, positioning them above the appropriate location on the circuit board. The hollow columns are then fixed, and the fixing bolts are rotated, causing the fixing bolts to move a limiting plate in conjunction with the hollow columns. As the limiting plate descends, the fixed columns pass through the sliding blocks and contact the circuit board. Multiple fixed columns secure the circuit board to the support plate, and the reaction force generated by the fixed columns further fixes the position of the hollow columns on the adjusting frame. Finally, an external power supply activates the cylinder body, which drives the punching head to punch the circuit board. This design improves the device's adaptability and ensures the quality of circuit board punching.
[0016] This circuit board punching anti-crack device, through the setting of a limiting frame, an adjusting plate, and an adjusting frame, first determines the position of the punching on the fixed circuit board, then uses the limiting bolt to adjust and fix the position of the adjusting plate within the limiting frame, and then adjusts the position of the adjusting frame on the adjusting plate and fixes the position of the adjusting frame on the adjusting plate by rotating the adjusting bolt on the column to lower the fixing plate, so that the punching head is located above the position of the circuit board to be punched, achieving the effect of facilitating the adjustment of the punching position.
