  • ROLL-TO-ROLL ELECTROCHEMICAL POLISH APPARATUS
    Publication number: 20140326595
    Abstract: A roll-to-roll electrochemical polish apparatus has a first rotator, a transporting device, a pre-treatment device, an electrochemical polish device, a post-treatment device, and a second rotator. The first rotator serves to rotatably spread out a metal foil roll to a metal foil. The transporting device receives and delivers the metal foil. The pre-treatment device receives the metal foil delivered by the transporting device for cleaning and drying the surface of the metal foil. The electrochemical polish device receives the metal foil outputted from the pre-treatment device for polishing the surface of the metal foil. The post-treatment device receives the metal foil outputted from the electrochemical polish device for cleaning and drying the surface of the metal foil. The second rotator serves to wind the metal foil outputted from the post-treatment device into a finished metal foil roll.
