The assembly line mainly consists of a hot press machine, logistics line, X-RAY, welding line (pre welding and tab welding), packaging line (high-speed punching machine, packaging machine, PET film packaging), injection line (rotary table and straight line, static and spray code), Degas, and inspection machine. The key workstations include: hot pressing module, pole ear pre welding module, pole ear cutting module, pole ear final welding module, welding CCD detection module, X-ray detection module, aluminum-plastic mold punching forming module, battery cell shell insertion module, top side sealing module, spray code module, PET film packaging module, liquid injection module, vacuum static module, vacuum packaging module, vacuum packaging module, Degas S. Folding forming, VOC detection, and appearance detection modules. 

The equipment is automatically transferred internally, and each individual machine is connected through logistics lines and caching to achieve standardized, modular, lightweight, intelligent, flexible, and information-based production and manufacturing.
