Description

Technical Field

[0001] This utility model relates to the field of battery cell cleaning, and in particular to a device for applying double-sided adhesive to battery cells. Background Technology

Using sheet-like double-sided adhesive also increases material costs. Utility Model Content

[0060] The fourth connecting plate 321 is provided with a first mounting hole 322, a second mounting hole 323, and a third mounting hole 324; the first mounting hole 322 and the third mounting hole 324 are located on both sides of the second mounting hole 323;

[0071] Working principle: The material strip 2 is installed on the feeding wheel 10 and then wound around the take-up wheel 20 after passing through the roller assembly; the take-up pressing roller 311 is controlled by tightening the handwheel 317 to press the release paper 21 onto the take-up active roller 32.
