Embodiment Construction

[0014]With reference to FIG. 1, a first embodiment of an electrochemical polish apparatus in accordance with the present invention has a first rotator 1, a transporting device 2, a pre-treatment device 3, an electrochemical polish device 4, a post-treatment device 5 and a second rotator 6.

[0015]The first rotator 1 serves to load a metal foil roll 11, is driven by a motor, which provides a power to steadily rotate the metal foil roll 11, such that a metal foil 12 of the metal foil roll 11 can be spread out. The first rotator 1 has a holder 13 mounted on the first rotator 1 for the metal foil roll 11 to be held by the holder 13 and keeps the metal foil 12 to be spread out in a right direction.

[0016]The transporting device 2 serves to deliver the metal foil 12, provides a conveying path for the metal foil 12, and one end of the conveying channel receives the metal foil 12 from the metal foil roll 11. The transporting device 2 has two ultrasound generators 21 respectively embedded in tw...

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.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority of Taiwanese Utility Model Application, No. 102208079, filed on May 2, 2013, the disclosure of which is herein incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention is related to a polish apparatus, and more particular to an roll-to-roll electrochemical polish apparatus carrying out a continuous electrochemical polish process on a metal foil roll by unrolling the metal foil roll, processing a metal foil of the metal foil roll, and winding the metal foil again into a metal foil roll.[0004]2. Description of the Related Art[0005]Flexible substrates are conventionally used in display devices and solar devices and usually need to be processed by a sequence of pre-treatments to ensure a desired quality of surfaces of the intermediate products for subsequent production processes and a preferred yield of the finished products.[0006]Electrochemical surfac...
