Flexible battery cell welding tool

Abstract

The invention relates to the technical field of battery cell welding, and discloses a flexible battery cell welding tool. The tool comprises an integrated cover plate and lower mounting plates, the lower mounting plates are located on the two sides of the lower end of the integrated cover plate, containing embedded blocks are fixedly arranged on the two sides of the lower end face of the integrated cover plate, upper hollow blocks are fixedly arranged on the upper end faces of the lower mounting plates, abutting bevel grooves are formed in the two sides of the inner wall of each containing groove, abutting stirring blocks are movably connected to the two sides of the interior of each upper hollow block, and abutting conical blocks are movably connected to the two sides of the lower end face of each containing embedded block. According to the tool, the integrated cover plate can be quickly and effectively disassembled and assembled, so that the disassembly and assembly operation of an external worker is facilitated; embedded limiting rods can be limited, so that the operation and processing of the external worker are facilitated; and meanwhile, battery cells with different lengths can be effectively limited and clamped, so that battery cells with different lengths can be processed.

Description

technical field [0001] The invention relates to the technical field of electric core welding, in particular to a flexible electric core welding tool. Background technique [0002] A cell refers to a single electrochemical cell containing positive and negative electrodes. It is generally not used directly. It is different from a battery that contains a protection circuit and a casing and can be used directly. The composition of a lithium-ion secondary rechargeable battery is as follows: cell + protection circuit Board, the rechargeable battery removes the protection circuit board, which is the battery core, which is the storage part of the rechargeable battery. The quality of the battery core directly determines the quality of the rechargeable battery. [0003] With the development of the new energy vehicle industry, the power battery used in the new energy vehicle is gradually replacing the traditional way of energy consumption into our life, the power battery system is huge...

AI Technical Summary

Problems solved by technology

[0004] Due to the diversification of new energy vehicles, customers' demand for lithium batteries is diversified, and the flexibility of the production line is insufficient, resulting in the limitation of lithium battery production, especially the welding and forming process of modules. Different forming methods of modules not only need to change the welding procedure , but also to update the tooling and fixtures at any time, which delays the production progress. The designer needs to constantly adjust the plan according to the on-site production environment during the design, which delays the design process. Therefore, in order to meet the diversified needs of customers and improve the efficiency of design and production, a design is designed. The flexible welding tool can change the molding method of the module according to the demand and improve the production efficiency. At the same time, a better installation mechanism is needed inside the welding tool to install it.
