Abstract

The invention provides a continuous plating device for films. The plating device comprises an unwinding machine, a winding machine, at least one main plating bath, a plurality of pairs of horizontal first conductive roller groups parallel to each other and a rectifier; a plurality of pairs of first anode groups parallel to each other and at least one first guide roller group parallel to the conductive rollers of the first conductive roller groups are non-horizontally arranged in the main plating bath; the conductive rollers of the first conductive roller groups are arranged above the main plating bath and correspond to the anodes of the first anode groups; and each pair of conductive rollers of the first conductive roller groups comprises two adjacent conductive rollers. The invention also provides a method for performing continuous plating on the films. When the continuous plating device is adopted to perform continuous plating on the films, any one or two surfaces of each film can be plated selectively at the same time, and therefore the flexibility of the plating operation and the production efficiency are improved.

Description

technical field [0001] The invention relates to a continuous electroplating device for thin films and a method for continuously electroplating thin films using the device. Background technique [0002] Existing electroplating devices are generally not suitable for electroplating thin films, especially for continuous electroplating of thin films. In order to overcome this technical problem, CN101350315A discloses a method for manufacturing a metal-clad polyimide substrate, in which an electroplating device is used. The electroplating device is composed of a roller for conveying the sheet and supplying power to the metal coating, and an electroplating device having at least two tanks with an anode opposite to the metal coating, see figure 1 . exist figure 1 Among them, 1 is an electroplating tank, 2 is a conveying sheet, 3 is a power supply roller, 4 is a reverse roller, and 5-17 are anodes. A polyimide sheet having a fixed width having a metal coating is continuously supp...
