Description

Technical Field

[0001] The invention relates to the field of electroplating, and in particular to an automatic variable-pitch rotating hanging device. Background Art

[0002] In electroplating production, due to differences in electroplating process flow, different products need to be produced in different production lines, which requires frequent switching of product flows. In traditional production scenarios, manual transfer and hanging are performed. With the popularization of automation, some manufacturers have begun to use automatic transfer and hanging mechanisms. Currently, the main mechanism on the market is automatic equidistant transfer and hanging mechanisms.
