Battery core assembly jig and battery core assembly method

Abstract

The invention belongs to the technical field of battery packaging and particularly relates to a battery core assembly jig and a battery core assembly method. The battery core assembly jig comprises ahot melting platform, wherein the hot melting platform is used for positioning an insulating protection film, first insulating stop frames and second insulating stop frames; the hot melting platform comprises a substrate; the upper surface of the substrate comprises a first end and a second end; first positioning components are symmetrically distributed at two sides of the first end and are used for placing and positioning the first insulating stop frames; second positioning components are arranged at the symmetrical parts at two sides of the second end and are used for placing and positioningthe second insulating stop frames; and each of the first positioning components and / or the second positioning components also comprises a structure for positioning the insulating protection film. According to the battery core assembly jig and the battery core assembly method, hot melting of the insulating stop frames and the insulating protection film in plane can be achieved in the battery coreassembly process, hot melting in plane is easier to achieve than hot melting in three-dimensional space, and operations in positioning, hot melting and assembly processes are simple and convenient.

Description

Technical field [0001] The invention belongs to the technical field of battery packaging, and in particular relates to a cell assembly fixture and a cell assembly method. Background technique [0002] In addition to small 3C products, the battery is mainly used as a power source or a backup power source for energy storage. Among them, the insulating protective film, the insulating stop frame, and the lower plastic part of the top cover are used as the battery insulation protection structure, which is a simple safety protection and fixing device commonly used in the latter two types of large batteries. [0003] Generally, the corresponding hot-melt fixtures and assembly tools are made according to the different cell structure, assembly method, and hot-melt method. At present, it is commonly used to directly heat-fuse the insulating protective film on the plastic part under the top cover. It is necessary to fix the relative position of the cell and the insulating protective film wit...
