Description

Technical Field

[0001] The utility model belongs to the technical field of PCB drill pins and relates to a PCB drill pin coating device. Background Art

[0002] Printed circuit boards are key interconnecting components used to assemble electronic parts and are known as the "mother of electronic products." With the development of electronic equipment, PCB products are currently moving towards high precision, high integration, and low cost. The thickness of the boards and the variety of apertures are increasing, and the demand for drilling is becoming more and more vigorous, resulting in more and more demands for the blade length, blade diameter, and number of holes drilled of the drill bit. As a result, there are also many specifications for the blade length and blade diameter of PCB drill bits. Moreover, with the growth of customer customization needs, the number of specifications is still showing an explosive trend.

[0003] In order to improve the service life of the drill bit, forming a coating on the surface of the drill bit is one of the important research directions. According to the characteristics of the coating, the drill bit is given corresponding performance, such as high hardness and high wear resistance. When coating the drill bit, the drill bit needs to be placed in a coating furnace and then coated by electromagnetic technology. The existing drill bit needs to be placed on the cutter head inside the coating furnace. According to the different sizes of the PCB drill bit, different fixing brackets need to be replaced to maintain the appropriate spacing. After installation, it is also necessary to adjust the height of the PCB drill bit by adjusting the fixing bracket so that the blade of the PCB drill bit is in the magnetic field coating area of the coating furnace, thereby coating the blade of the PCB drill bit. The height adjustment steps of the PCB drill bit of the existing equipment are cumbersome and inconvenient for the installation of the PCB drill bit. Therefore, we propose a PCB drill bit coating device. Utility Model Content
