Description

TECHNICAL FIELD

[0002] In today's mobile phone manufacturing industry, the traditional mobile phone screen back lens pasting film process has been a key and delicate step. In this process, the transfer mechanism plays a crucial role, which is responsible for accurately transferring the workpiece to be pasted to the film from one end of the production line, i.e. the feeding and discharging end, to the film pasting station at the other end. Specifically, this traditional transfer mechanism is designed with a single loading platform, which means that during feeding and discharging, it can only perform a single action, i.e. it can only complete the discharging operation before feeding.
