New Energy Vehicle - Body-in-White Welding Application Case
桥田
Application Background
An automotive body-in-white welding automation system integrator undertook a welding production line relocation and integration project for a high-end independent brand's new energy vehicle plant. The project required relocating an aluminum spot welding production line for a pure electric mid-size sedan from the original plant to the new plant as a whole. The project demanded complete migration of the tool quick changer system and rapid restoration of production capacity, posing challenges to product compatibility and rapid deployment capability.
Sore Point
桥田
1. Challenges of plant relocation and production line reconstruction: The production line needed to be relocated to the new plant as a whole, requiring complete migration of the tool quick changer system and rapid restoration of production capacity, placing extremely high demands on product compatibility and rapid deployment capability. 2. Stringent reliability requirements for aluminum spot welding: Aluminum spot welding is a core process in body manufacturing for high-end new energy vehicles, imposing extremely high requirements on the repeat positioning accuracy, electrical interface stability, and safety of the welding gun tool quick changer, with no production interruptions permitted. 3. Need to meet the highest functional safety level: The automaker's welding line has strict requirements for the tool changer's safety circuit, requiring compliance with Performance Level d, Category 3 safety standards, which ordinary products struggle to meet.
