Description

Technical Field

[0001] The present application relates to the technical field of lithium battery production equipment, and in particular to a lithium battery shaping and flattening processing mechanism. Background Art

[0002] The main board of a lithium battery is made by pressing a liquid conductive material into a solid state, and then cutting it according to the shape required by the lithium battery to obtain a conductive material of a specific shape. After cutting, the conductive material is then sealed to isolate the conductive material from the outside world.

[0003] Generally, the edges of the positive and negative electrodes of lithium batteries are set in a stepped shape to facilitate the assembly of lithium batteries in the later stage. After the edge sealing operation of the conductive material is completed, there are metal edges near the positive and negative electrodes. The next step is to use adhesive tape to cover these metal edges.

[0004] However, the edges of the positive and negative electrodes of the lithium battery are stepped, resulting in bulges formed by edge sealing scraps at both ends of the step after the edge sealing operation, which is not convenient for the subsequent wrapping operation using adhesive tape and the wrapping effect is poor. Utility Model Content
