[0003] Many shells of existing electronic products are irregular in shape. Electronic products generally have button holes for buttons. After the shell is manufactured, a drilling machine is needed to punch holes. The existing punching equipment generally has a pressing positioning component. , but the pressing and positioning component has a good positioning effect for punching holes in regular and straight shells or boards, but when pressing and punching irregular shells, the force on the shell is not uniform, and it is easy to punch holes on the one hand. Offset occurs, causing the drilled hole to deviate from the target position. On the other hand, when the drill bit is drilling the shell, the shell is prone to local cracking, resulting in a decrease in drilling efficiency and success rate.

The invention discloses a reproducible positioning and punching device for irregular casings of electronic products, which belongs to the technical field of punching electronic products. , before punching holes, the shape of the irregular shell surface is reproduced. In this process, through multiple longitudinal replica needles, under the action of the guide hole and the return limit wire, the force is reduced so that it is consistent with the irregular shell surface shape After complete engraving, the multi-state positioning capsule is used to fix the longitudinal engraving pins, and the shapes of multiple longitudinal engraving pins are kept. At this time, the pressing and positioning components are used to apply force to the irregular shell At the same time, there will be no blank area on the lower surface of the irregular shell, making it more stable when punching, so that the success rate and efficiency of punching are effectively improved. The needle automatically returns to its original position, which is convenient for the next punching.
Description
technical field [0001] The invention relates to the technical field of punching holes for electronic products, and more specifically relates to a reproducible positioning punching device for irregular shells of electronic products. Background technique [0002] The shell of electronic products is the case, and the materials include polycarbonate PC, ABS engineering plastics, etc. According to the purpose, the casing can be divided into: computer casing, TV casing, mobile phone casing, instrumentation casing, motor casing, micro motor casing, etc. According to the material, it can be divided into plastic casing, alloy casing, composite material casing and so on. [0003] Many shells of existing electronic products are irregular in shape. Electronic products generally have button holes for buttons. After the shell is manufactured, a drilling machine is needed to punch holes. The existing punching equipment generally has a pressing positioning component. , but the pressing an...
