Background The lithium copper foil is a key material of a negative current collector of the lithium ion battery. With the improvement of the performance requirement of the battery, the thickness of the copper foil is continuously thinned. Because the ultrathin copper foil has extremely high activity, oxidation reaction is extremely easy to occur when the ultrathin copper foil is exposed to air, so that the conductivity of the battery is influenced. The copper foil finished product coil must be strictly sealed and packaged before leaving the factory; The existing packaging equipment is difficult to realize accurate centering of materials with different sizes at the same station, so that packaging offset is caused. The copper foil roll has large weight and the foil is extremely fragile, and in the automatic conveying and positioning process, the rigid impact is extremely easy to cause the foil to generate indentation or edge deformation. When the traditional automatic packaging device is used for processing the edge folding of the end face, the end face cannot be closely attached, so that the subsequent hot-melting seal is not tight, and the requirement of vacuum anti-oxidation storage is difficult to meet. The procedures of film coating, edge folding, vacuumizing and the like are often dispersed on different equipment, so that the material transferring times are increased, the scratch risk is increased, and the production efficiency is limited.
