Description

Technical Field

[0001] The invention relates to the field of battery welding, and in particular to a battery welding production line. Background Art

[0002] During the production process of batteries, it is necessary to weld the batteries placed on the jig. In order to improve welding efficiency, a battery automatic welding system is usually designed to weld batteries in batches and efficiently, such as the Chinese invention patent with publication number CN117817212A, entitled Welding System, Battery Production Line and Welding Method. The welding system includes a welding assembly, a loading assembly, and a driving assembly; the loading assembly is movably arranged on the frame, and each loading position is correspondingly provided with a loading assembly, and the loading assemblies corresponding to the multiple loading positions are connected in sequence, the loading assembly is used to carry bare cells, and the welding assembly is used to weld the bare cells carried by the loading assembly at the welding position. Although these welding devices such as welding systems and battery production lines can weld batteries quickly and efficiently. However, in actual production, these existing welding devices still have the following significant deficiencies in the process of transporting battery loading jigs: the driving device of the battery loading jig generally uses a conveyor belt or other transport mechanism to form a transport line to complete automatic and efficient battery transmission; among them, when the battery loading jig is placed at a preset position on the conveying line, there will be an installation error in the position, and when the battery loading jig is subsequently transported, there will also be a position offset between the battery loading jig and the conveying line. Correspondingly, there will be a large error between the position of the battery and the processing position of the battery, and the welding head cannot accurately align with the position of the battery to be processed, resulting in frequent welding deviation and cold welding during the welding process, which not only increases production costs, but also seriously reduces the production yield of the battery.
