Description

[0002] Among the current lithium battery equipment, wound cells are used by many lithium battery manufacturers due to their stable battery performance and high manufacturing efficiency. They account for a large market share, so the demand for corresponding battery winding machines is also large.

[0003] However, in the existing winding machines for square lithium batteries on the market, after winding the lithium battery, the winding machine needs to stick the tail tape to the end of the wound lithium battery to prevent the wound diaphragm from loosening. However, the tape cutting and sticking of the existing tail sticking device are independently set, and the battery cell needs to complete two processes to complete the tail sticking. At the same time, because the tape of the tape roll has a certain viscosity, the tape directly from the unwinding place will have excessive traction tension when cutting, causing the cut tape to be over-stretched. When the stretched tape is pasted on the tail of the battery cell, it will shrink and stretch unevenly due to the loosening of the tape after stretching, resulting in poor tape bonding effect, weak bonding at the tail of the battery cell, and easy to cause uneven bonding at the tail of the battery cell. When the battery cell is pressed together, it will cause expansion and affect the quality of the battery cell. Utility Model Content
