The assembly line has realized the automation of the whole process of battery and module loading, sorting, assembly, welding, testing and other links, with a stable rhythm. At this stage, the automatic detection system, automatic calibration and automatic processing system are added in the key steps of production, which completely uses the manipulator to replace the traditional manual complicated operation and ensure the stability of product quality. At present, the actual operation data show that the overall operation of the production line is safe and stable, the processing efficiency is high, and the quality of products is stable.
