Description

Technical Field

[0001] The utility model relates to the technical field of conductive film production, in particular to a connecting rod type evaporation baffle and coating equipment. Background Art

[0002] Conductive film is a polymer material with copper or aluminum layers plated on the top and bottom surfaces of substrates such as PET and PP. It has a sandwich structure and is also called a composite thin film current collector. It is a type of material with many good properties and is widely used in lithium-ion batteries, mainly as a battery current collector in lithium-ion batteries.

[0003] In the production of conductive films, vacuum evaporation can be used, which refers to a process in which a certain heating evaporation method is used to evaporate the coating material (or film material) under vacuum conditions and gasify it, so that the particles fly to the surface of the substrate and condense into a film. Evaporation is an earlier and more widely used vapor deposition technology, with the advantages of simple film formation method, high film purity and density, and unique film structure and performance.

[0004] During coating, the film material is generally placed in a crucible on the evaporation tank for heating and evaporation. Before the film material is heated to the evaporation temperature or after the coating is completed, a baffle with cooling liquid inside needs to be set between the base film and the film material. The baffle moves horizontally between the main roller and the evaporation tank to prevent excess or unstable film material from evaporating onto the base film or cooling roller, so that excess film material is plated onto the baffle. However, during the heating process, the baffle is prone to deformation and bending after being heated. The two ends of the baffle are prone to bend upward to form an arc, and the baffle is prone to get stuck during movement, causing the baffle to fail to shield the evaporation tank, affecting the production capacity and effect of coating.

[0005] The above defects need to be solved urgently. Utility Model Content
