Lithium battery side rubberizing equipment

Abstract

The invention relates to the technical field of lithium battery production equipment, in particular to lithium battery side rubberizing equipment. An unwinding assembly, a winding assembly, a cutting assembly, a glue taking assembly, a glue pushing assembly and a clamping assembly are sequentially arranged on a vertical plate from top to bottom. Primer of the adhesive tape is conveyed and collected through the winding assembly, then separation and conveying of the primer and the double-faced adhesive tape are achieved, the function of attaching the double-faced adhesive tape is achieved, the double-faced adhesive tape of the adhesive tape is straightened through the clamping assembly so that the cutting assembly can cut the double-faced adhesive tape, the cut double-faced adhesive tape is obtained through the adhesive taking assembly, and the double-faced adhesive tape is attached to the side edge of a battery cell. The double-faced adhesive tape is pushed through the adhesive pushing assembly and is attached to the bottom face and the top face of the battery cell, then the adhesive tape is attached to the battery cell in a C shape, the adhesive pushing assembly can be compatible with the battery cells of various thickness sizes, the side adhesive tape attaching mechanisms are arranged side by side by being installed on the vertical plate, and then adhesive tape attaching is conducted on the multiple battery cells at the same time. The occupied space is reduced, and the productivity is greatly improved.

Description

Technical field [0001] The present invention relates to the technical field of lithium battery production equipment, and more particularly to a lithium battery side gel device. Background technique [0002] During the battery cell manufacturing of rectangular batteries such as lithium batteries, the cells need to be gelatinated, and the tape is attached to the side of the battery from the side of the battery, the top and bottom surface, so that the tape is "c" shape On the battery cell, most of the prior art is mostly a sticker tape, directly intercepting a single-sided tape and attaches the paste surface to the cell. However, for double-sided tape, it is necessary to separate double-sided tape and primer waste during the refueling, thereby intercepting double-sided tape stickers, and the prior art cannot satisfy the glue function of double-sided tape. For different thicknesses, existing adhesive devices require different procedures to change the gelatin action, cumbersome operat...

AI Technical Summary

Problems solved by technology

However, for the double-sided tape, it is necessary to separate the double-sided tape and the bottom glue waste during the retrieving process, and then intercept the double-sided tape and stick it on. The existing technology cannot meet the glue application function of the double-sided tape.

For batteries with different thicknesses, the existing gluing device needs to set different programs to change the gluing action, which is cumbersome to operate and has low compatibility, which is not conducive to efficient production

Moreover, the existing gluing device applies gluing to the battery cells one by one, and the production efficiency is low. If multiple gluing devices are used for the gluing process at the same time, due to the large size of the gluing device, it will take up a lot of space, high cost and low return.
