Description

Technical Field

[0001] The utility model relates to the technical field of circuit board drilling, in particular to a stable drilling processing device for circuit board production. Background Technique

[0002] The names of circuit boards include: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high-frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed circuit board, etc. Circuit boards miniaturize and visualize circuits, playing an important role in the mass production of fixed circuits and optimizing the layout of electrical appliances. Circuit boards can be called printed wiring boards or printed circuit boards. FPC circuit boards, also known as flexible circuit boards, are printed circuit boards made of polyimide or polyester film as the substrate, with high reliability and excellent flexibility. They have the characteristics of high wiring density, light weight, thin thickness, and good bendability.

[0003] For example, the patent document with the publication number CN 219926234 U discloses a PCB circuit board drilling mechanism, which relates to the field of PCB circuit board manufacturing. It includes a workbench, and a support frame is fixedly installed at the top of the workbench near the edge position. A first forward and reverse motor is fixedly installed at the top of the workbench and inside the support frame. In the utility model, the waste generated by the drilling of the PCB circuit board by the drilling tool can be directly taken to the collection box, avoiding the waste from falling onto the PCB circuit board. The first forward and reverse motor rotates to drive the lead screw to rotate. Driven by the lead screw, the moving block moves downward and drives the pressing plate to press down, pressing the PCB circuit board tightly. And when the drilling tool is drilling, the lower pressing plate is always in the pressed state, ensuring that the PCB circuit board will not shake, improving the product qualification rate. By removing the fixing cap and pulling out the fixing bolt from the second circular through hole and the third circular through hole, the rapid replacement of the drilling tool is realized, improving the replacement efficiency.

[0004] However, during the drilling processing of circuit board production, due to the limitations of its own structure, the drilling position of the circuit board can only be adjusted manually, with low adjustment efficiency. There may be problems of insecure fixation caused by frequent position adjustments, affecting the overall stability of the equipment for circuit board production drilling. At the same time, the equipment can only perform a one-way downward pressing drilling operation, unable to stably position the drill bit at the drilling position and perform efficient chip suction operation at the drilling area, unable to meet the daily use requirements. Therefore, it is urgent to design a stable drilling processing device for circuit board production to solve the above problems. Summary of the Invention
