Description

Technical Field

[0001] The invention relates to the field of watch parts processing, in particular to an assembly device for a watch case. Background Art

[0002] A watch, or wristwatch, is an instrument worn on the wrist for timing and displaying time. A watch is usually made of leather, rubber, nylon cloth, stainless steel and other materials to make a strap, and the watch head that displays time is tied to the wrist. However, the inner shell and outer shell of a traditional watch case are mostly fixed together, so it is not convenient to disassemble and assemble the inner shell and outer shell. The BOSS column is a common assembly structure on home appliances and automobile interior and exterior plastic parts, which mainly plays a positioning and fastening role. The partially detachable inner shell and outer shell are fixed by screws and BOSS columns. The watch shell parts are processed by CNC, and the processed BOSS column is assembled in the corresponding hole on the shell part and fixed by laser welding. However, due to the high processing precision and complex structure of the watch shell parts, the watch shell parts are traditionally assembled manually with the BOSS column. The watch shell parts lack suitable fixtures to fix the shell parts during the assembly process of the BOSS column. Summary of the invention
