Description

Technical Field

[0001] This utility model relates to the field of watch strap pressing equipment technology, and in particular to a dual-station pressing mechanism. Background Technology

[0002] In the precision machinery manufacturing industry, especially in watchmaking, watch strap assembly is a crucial step. In recent years, with the development of automation and precision manufacturing technologies, automated watch strap pressing machines have been gradually introduced into the production process to improve assembly efficiency and precision. However, existing watch strap pressing machines still have some significant shortcomings:

After pressing one watch band, it needs to be removed before the next watch band is installed and pressed. This single-station operation method results in low production efficiency and cannot meet the needs of large-scale production. Utility Model Content
