Technical Field

[0001] The utility model relates to the technical field of lithium battery coating diaphragms, in particular to a coating roller capable of quickly switching between a coating area and a blank area. Background Art

[0002] The so-called battery coating refers to a method of coating a paste polymer, a molten polymer or a polymer solution on a diaphragm to obtain a composite film. For lithium-ion batteries, the coated diaphragm is a metal foil, generally a copper foil or an aluminum foil. The entire coating process is a series of continuous steps from placing the substrate into the coater to the coated substrate coming out of the coater. In order to achieve intermittent coating, that is, to form an intermittent blank area on the base tape, a groove is usually provided on the coating roller, so that during the coating process, the groove of the coating roller does not contact the base tape, thereby forming an intermittent blank area on the base tape. However, the coating area and the blank area cannot be changed in the above scheme. In actual use, different areas on the surface of the substrate need to be blanked according to different needs.
