Technical Field

The invention belongs to the field of batteries, and particularly relates to a lithium battery tab and adapter plate welding module.

Background

The assembly process of the shell power lithium ion battery above the market at present is mainly finished by using traditional process equipment, and comprises main process procedures of cell pressure shaping, cell rubberizing pairing, ultrasonic welding of a lug and a connecting sheet, laser welding of the connecting sheet and a top cover, coating of an insulating film, cell shell entering, top cover and shell pre-welding (also called top cover pre-welding), top cover and shell full-welding and the like so as to realize the assembly process of single cell or combination of multiple cells into the shell.

The end-to-end connection order between traditional battery assembly scheme process is clear and definite, uses independent thing streamline to carry each process equipment with electric core tool and auxiliary material tool to accomplish the material and carry. However, the assembly scheme involves more process equipment, the layout mode is numerous and complicated, and the efficiency of the comprehensive equipment which can be achieved after each equipment is connected in series is low; the method is characterized by frequent material replacement among equipment, high probability of mutual restriction of downtime, proficiency of personnel operation and the like.

In conclusion, although the existing battery assembly scheme can well meet the manufacturing requirement, the comprehensive benefit level is low. Particularly, the existing tab welding equipment and the existing adapter plate laser welding equipment are connected by an logistics line and a tray, so that the occupied space is large, the equipment cost is high, and the auxiliary structural members of the cell product are more in the tab welding process and the adapter plate laser welding process, so that the manual feeding is required frequently, and the time and the labor are consumed; meanwhile, the traditional single machine equipment fixtures are more in types, and the battery cell is frequently transported and transferred during operation, so that the product consistency is poor, and the excellent rate is difficult to improve; in addition, the traditional single machine equipment is controlled by independent programs respectively, and people corresponding to the number of machines need to be configured for operation, so that more artificial uncertain interference factors are brought to the product quality.
