Description

Protective layer recovery device for rolled copper foil

Technical field

The present invention relates to a machine for separately stacking strips such as rolled copper foil, and more particularly to a protective layer recovery apparatus for rolled copper foil.

Background technique

Some rolled copper foils have a layer of adhesive such as double-sided tape. Because the copper foil is attached with a protective layer, such as a protective film or protective paper, to protect the adhesive on the copper foil surface. When it is necessary to peel off the protective film or the protective paper, then use copper foil.

For the treatment of the protective layer on the surface of the rolled copper foil, the prior art has mainly focused on the automatic peeling device of the copper foil and the protective layer. For example, some copper foil stripping devices in the prior art include an adsorption carrying module that can flatten the adsorbed copper foil, and a sliding module having elastic stripping to partially peel off the protective layer from the copper foil, and the protective layer of the partially peeled copper foil can be blown away from the copper.
