​The《New Energy Automobile Industry Development Plan》 was released, and the power battery industry has received great benefits again, and battery companies have stepped up their layout. However, the production of lithium batteries is complex and requires about 10 processes from raw materials to finished batteries. Each process will minimize human intervention to ensure the safety and consistency of the final finished battery cells. To improve the level of automated production, it is necessary to improve on the agenda.

For the whole process production line of the lithium battery industry, STEP Group provides a complete set of automation solutions. Based on Zhongweixing bus controller/card, servo, and HMI, it can realize motion control solutions for equipment and line bodies in various process segments from electrode production, cell assembly to post-processing, ensuring production and processing accuracy and stability.

The SCARA robot, combined with AVS vision, can quickly connect multiple processes such as lamination, tab pre-welding, inspection, welding, gluing, coating, hot-melting, and shelling, and complete flexible operations that focus on upper and lower materials.

1.
The process in which the spot welding lug and the base are fused together through the welding head.

2. The lamination
assembles the positive and negative electrodes and the diaphragm together, and after the glue is pasted, the pole core is formed.
