It includes major processes such as hot pressing of cells, X-ray, ultrasonic welding and pairing, butterfly welding of cells, cell assembly, wrapping with Mylar film, cell insertion into the casing, pre-welding of the top cover and casing, and full welding of the top cover and casing, with the assembly process of combining two cells into the casing.

[0003] The adapter welding equipment is one step in the assembly process of prismatic lithium-ion batteries. Currently, the production line's cell capacity is 210AH, and each battery is composed of two cells. To connect the two cells, the equipment uses a butterfly welding process to connect the cell to the top cover. However, the current cell size is thicker than the original, making the existing welding technology insufficient for the requirements of thicker cells. Furthermore, how to connect the top cover to the cell? How to achieve the bonding process between the two cells after welding? These are all pressing problems that need to be solved.

Each second gripping component rotates in a clockwise circular motion along with the rotating end of the core-coating rotating mechanism 21. The spacing between adjacent second gripping components is consistent with the spacing between the tail adhesive application mechanism 22 and the side adhesive application mechanism 23. The flipped battery cells are then sequentially gripped and placed on the core-coating rotating mechanism 21.
