Abstract

The invention discloses a novel battery module welding tooling structure, comprising a bottom plate, the upper surface of the bottom plate is fixedly connected with a support plate, the surface of the support plate is fixedly connected with a cylinder, and the upper surface of the support plate is fixedly connected with a The top plate, the upper surface of the top plate is slidably connected to the battery fixing plate, and the upper surface of the top plate is fixedly connected to the rib and the stopper respectively, and the front end of the steel sleeve can adopt a conical structure by pressing the steel sleeve during use. The inclined surface of the row groove is fitted to ensure the concentricity of the parallel row and the negative shrapnel. During use, when the cylinder is pressed, the tail spring provides a pressing force to make up for the gap caused by the tolerance of the parts, ensuring that the cells and the parallel row , The close fit of the negative shrapnel can make the functional compatibility good during use. One fixture has multiple module welding functions, and the addition of pads and welding bottom plates can realize negative module welding and positive module welding respectively. And intermediate module welding function.

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...
