Welding system and welding method of module side plate

Abstract

The invention relates to the technical field of production of batteries, and discloses a welding system and a welding method of a module side plate. The welding system comprises a welding fixed tool and welding equipment, wherein the welding fixed tool comprises a fixed unit; the fixed unit comprises a mounting plate, pressing plates and a pushing structure; the mounting plate is hoisted on a support assembly; the two oppositely-arranged pressing plates are connected with the mounting plate in the first direction in a sliding manner and are connected with the pushing structure which is arranged in the first direction; positioning grooves which are matched with positions of welding seams are formed in the pressing plates; the welding equipment is arranged on the side face of the welding fixed tool; the welding equipment comprises a displacement driving structure and a welding headpiece; and the welding headpiece is connected with the displacement driving structure. According to the welding system and the welding method of the module side plate provided by the invention, due to arrangement of the welding fixed tool, the positions of the welding seams of workpieces are pressed tightlyand fixed in a pertinent manner, limitation of the positions of the welding seams is facilitated, the positioning accuracy of welding positions of the workpiece is improved, and welding errors are reduced.

Description

technical field [0001] The invention relates to the technical field of battery production, in particular to a welding system and a module side plate welding method. Background technique [0002] In today's increasingly fierce energy competition, it has become a consensus to look for products to replace petroleum energy. Among them, the vigorous development of the battery industry will be a trend, which has a wide range of applications in industrial production and life, and urban electric buses have quietly started. The battery cell is an important component unit of the battery. The battery is first assembled into a battery cell module, and then the battery module is packaged in a soft package. [0003] Some battery modules include a square frame and batteries arranged in the square frame. The square frame is welded by two opposite end plates and side plates. The welding quality determines the processing quality of the battery module. Therefore, the mold The requirements fo...
