Abstract

The invention is applicable to the technical field of batteries, and provides a battery cover plate and a cover plate welding tooling, and a battery preparation method. The battery cover plate comprises the following parts of a cover body provided with positive and negative terminals; a positive conductive member for connecting the positive terminal and a positive tab of a cell, wherein one end ofthe positive conductive member is fixedly welded to the bottom of the positive terminal; and a negative conductive member for connecting the negative terminal and a negative tab of the cell, whereinone end of the negative conductive member is fixedly welded to the bottom of the negative terminal, and an insulating member is disposed between the positive terminal and / or the negative terminal andthe cover body. The cover plate welding tooling is used for welding the battery cover plate and the cell and comprises a first cell fixing member, a second cell fixing member and a cover plate bearingmember. The battery cover plate provided by the invention, with no need to perform welding between the positive conductive member and the positive terminal and the negative conductive member and thenegative terminal, can effectively prevent the welding dust from entering the cell, thereby greatly reducing the safety control difficulty during the battery preparation process and reducing securityrisks.

Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to a battery cover plate, a welding tool for the cover plate, and a battery preparation method. Background technique [0002] At present, in the cover plate structure of the existing battery, there are scattered and independent parts between the connecting piece and the cover plate. Welding between cell lugs. In this way, during the assembly process, two welding operations are required, and powder and dust will be generated inside the battery during the welding operation, which will bring safety hazards to the manufacturing process and use of the battery. Contents of the invention [0003] In view of this, the present invention provides a battery cover plate, a welding tool for the cover plate, and a battery preparation method to solve the problem of dust generated during the battery manufacturing process. [0004] In order to solve the above problems, the technica...
