Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a glue sticking mechanism. Background Art

[0002] The manufacture of battery cells is completed by combining the winding process and the film-making process. Among them, the film-making process is the front process, and the winding process is the back process. The film-making process is the process of welding the pole ears to the pole pieces, and the winding process is the process of winding the pole pieces made by the film-making process into a battery cell. The current problem is that after winding a battery cell, the pole pieces need to be cut off. However, after cutting off the pole pieces, burrs will be generated. These burrs will pierce the diaphragm and cause the battery cell to short-circuit. In addition, when the pole pieces are cut off, powder will fall on the battery cell, and the pole pieces at the first fold position and the second fold position of the inner circle of the battery cell will seriously lose powder, affecting the quality of the battery cell.
