Novel battery module welding tool structure

Abstract

The invention discloses a novel battery module welding tool structure. The novel battery module welding tool structure comprises a bottom plate, the upper surface of the bottom plate is fixedly connected with a supporting plate, the surface of the supporting plate is fixedly connected with an air cylinder, the upper surface of the supporting plate is fixedly connected with a top plate, the upper surface of the top plate is in sliding connection with a battery fixing plate, and the upper surface of the top plate is separately and fixedly connected with a gear edge and a check block. In the useprocess, a tapered structure is adopted for the front ends of compaction steel bushings, the front ends of the compaction steel bushings can be attached to bevels of grooves of parallel connection rows, and the concentricity of the parallel connection rows and negative electrode bouncing pieces is guaranteed. In the use process, when the cylinder is compacted, tail springs provide compacting forceto make up for the gap brought by part tolerances, tight attachment of cells, the parallel connection rows and the negative electrode bouncing pieces is guaranteed, the function compatibility can begood in the use process, a fixture has multiple module welding functions, cushion columns and a welding bottom plate are increased, and thus the negative electrode module welding function, the positive electrode module welding function and the middle module welding function can be realized separately.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a novel battery module welding tooling structure. Background technique [0002] With the development of the lithium battery industry, in order to seize opportunities and reduce costs, a new type of battery module structure has been developed, which requires new tooling to support production. Traditional tooling uses probes to crimp tabs or metal plates to crimp busbars. method, the existing technology has the following problems: 1. The probe structure occupies the solderable area, and it cannot be used in batches in this module structure; Production cannot be realized in this module structure; 3. The traditional tooling crimping method cannot guarantee the tight combination of cells, parallel rows, and shrapnel during the welding process of the new module; 4. The welding consistency cannot be guaranteed; 5. During the welding process Easy welding, weak welding, explosive weldi...
