Cover plate assembly with battery aluminum adapter plate

Abstract

The invention discloses a cover plate assembly with a battery aluminum adapter piece, and aims to provide the cover plate assembly with the battery aluminum adapter piece, which can improve the bonding strength, improve the production efficiency and the yield and reduce the manufacturing cost. The cover plate comprises a cover plate body, a first switching piece is installed on the cover plate body, the first switching piece comprises a first switching piece body and an injection molding part, a first glue hanging hole and a second glue hanging hole are formed in the first switching piece body, and the injection molding part wraps one face of the first switching piece body and the side edge of the first switching piece body and penetrates through the first glue hanging hole. And the injection molding part is also coated on the other surface of the body of the adapter sheet I and penetrates through the glue hanging hole II. The invention has the following beneficial effects: a traditional PET film pasting part is cancelled, the upwarp phenomenon is avoided, the production process is simplified, and the manufacturing cost and the labor cost are reduced; the bonding strength of the injection molding part and the first adapter piece body is enhanced, and the production efficiency and the yield are greatly improved.

Description

technical field [0001] The invention relates to the related technical field of battery adapters, in particular to a cover plate assembly with an aluminum battery adapter. Background technique [0002] With the development of modern society and the enhancement of people's awareness of environmental protection, more and more devices choose lithium-ion batteries as power sources, such as mobile phones, notebook computers, power tools and electric vehicles, etc. This is the application and development of lithium-ion batteries. Provides a wide space. In the production process of lithium battery, the positive or negative electrode of the battery needs to be connected with the cover plate of the battery through an adapter. [0003] like Figure 9 and Figure 10 As shown, the existing aluminum adapter is generally assembled from PET film 33, injection molded parts 34 and hardware 35, which has many parts, complicated processing procedures and high manufacturing cost, and the PET f...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the many parts of the aluminum adapter sheet in the prior art, the processing procedure is complicated, the manufacturing cost is high, and the PET film can only cover one surface of the hardware, which is prone to missing film or sticking deflection. The strength is low, and it is prone to warping. It provides a cover plate assembly with battery aluminum adapters that can improve the bonding strength, improve production efficiency and yield, and reduce manufacturing costs.
