Abstract
Description
[Technical Field]
[0001] This invention belongs to the field of headphone charging case manufacturing technology, and particularly relates to an automated assembly line for headphone charging cases. [Background Technology]
[0002] The assembly process for the lower inner liner of the headphone charging case involves: installing the FPC, hot-melting the FPC, assembling the magnets, applying UV adhesive, drying the UV adhesive, assembling the mainboard, and locking the mainboard in place. Currently, these assemblies are all done manually using jigs. Specifically, workers first place the FPC board onto the charging case inner liner using positioning posts, then manually use a hot-melt machine to heat-melt the charging case inner liner and the FPC board together. Next, they manually install the magnets and apply adhesive. After the UV adhesive dries, they manually lock the mainboard onto the charging case inner liner. This process is time-consuming, labor-intensive, and inefficient. Furthermore, manual assembly increases the risk of accidents that could injure workers. [Summary of the Invention]
