Device used for edge folding of lithium battery and application method thereof

Abstract

The invention relates to a lithium battery processing device and a processing method, in particular to a device used for edge folding of a lithium battery and an application method thereof. The devicecomprises a horizontal base station and a vertical base station, wherein the vertical base station is arranged above the horizontal base station and at the left side of the horizontal base station, and two location bosses are arranged at the right side of the vertical base station; and a limiting base station is arranged above the right side of the horizontal base station. The method comprises the following steps: placing the lithium battery on the horizontal base station, and tightly pushing the end part of the lithium battery against the location bosses by the limiting base station, so thata to-be-buckled aluminum-plastic film extends out from the upward side of the vertical base station; maintaining the state that the to-be-buckled aluminum-plastic film extends out from the upward side of the vertical base station, heating the extended aluminum-plastic film by adopting a sealing head of heat sealing equipment and softening the aluminum-plastic film, then turning over the horizontal base station with the lithium battery for 90 degrees together, and buckling the extended aluminum-plastic film until the aluminum-plastic film fits with a panel at the right side of the vertical base station, so that edge folding of the lithium battery is completed. The device provided by the invention has the advantages that edge folding quality is improved, and edge folding safety is improved.

Description

technical field [0001] The invention relates to a lithium battery processing device and a processing method, in particular to a device for folding a lithium battery and a method for using the same to improve the quality and safety of the folding. Background technique [0002] After the lithium battery is packaged, it is generally folded, which not only makes the structure of the lithium battery more compact and beautiful, but also ensures the width of the edge of the lithium battery to ensure its tightness. [0003] At present, the method used for folding lithium batteries is manual ironing. The operation is to paste the battery directly on the surface of the sealing head of the packaging equipment, heat the aluminum-plastic film that needs to be bent, and then fold the edges. The disadvantages of this method are as follows: : [0004] (1) Due to the uneven folding technique and strength, it is easy to deform during the folding, the flatness of the folding is poor, and the ...

AI Technical Summary

Problems solved by technology

[0004] (1) Due to the uneven folding technique and strength, it is easy to deform during the folding, the flatness of the folding is poor, and the thickness is uneven;

[0005] (2) The deformation at the folded edge may be transmitted to the main body of the battery, causing the battery powder to fall off, and even lead to internal failure of the battery;

[0006] (3) Since the bent part is at right angles and the force is uneven, it is easy to cause damage to the bent part;

[0007] (4) Workers are prone to burns during operation, which poses a safety hazard

[0008] At present, other tools are used to assist in the folding operation, but some are not easy to use, and some cannot solve the above problems

[0009] In summary, the existing lithium battery hemming devices and hemming processing methods have poor hemming quality and low hemming safety
