Lithium battery processing equipment and using method thereof

Abstract

The present invention relates to a lithium battery processing equipment and a using method thereof, pertaining to the technical field of lithium battery production. The equipment comprises a roller and two fixing blocks. Both ends of the roller are rotatably connected on the two fixing blocks separately, the roller is located right above a circular-arc-shaped chamfer, and a pace used for passing through an aluminum-plastic film is arranged between the roller and the circular-arc-shaped chamfer. The method comprises the following steps: a lithium battery is placed on a horizontal base platformof a lithium battery edge-folding device; the horizontal base platform is rotated to the position of contacting with a chock block exactly, the roller is exactly located above the circular-arc-shapedchamfer at the moment, and the aluminum-plastic film passes through the space between the roller and the circular-arc-shaped chamfer of a vertical base platform; the protruding aluminum-plastic film is heated and softened by using the head of a heat sealing equipment; the fixing blocks and the edge-folding device are allowed to rotate relatively after the heating and the softening are completed, and the roller rotates along a circular-arc surface of the chamfer to press the aluminum-plastic film towards the circular-arc surface and allow the aluminum-plastic film to bend. The equipment and themethod can improve the edge-folding quality and the edge-folding safety.

Description

Technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a lithium battery processing equipment for improving the quality of folding edges and a use method thereof. Background technique [0002] After the lithium battery is packaged, it is generally folded, which can not only make the structure of the lithium battery more compact and beautiful, but also ensure the sealing width of the lithium battery to ensure its tightness. [0003] At present, the method used for the edge folding of lithium batteries is to manually fold the edges. The operation is to directly attach the battery to the surface of the sealing head of the packaging device to heat the aluminum-plastic film that needs to be bent, and then fold the edges. The disadvantages of this method are: : [0004] (1) Due to the uneven folding technique and strength, it is easy to deform when folding, the flatness of the folding is poor, and the thickness is uneven; [0005...

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

However, after the actual operation, the effect of improving the quality of the hemming is far from meeting expectations.
