Plating bath cathode wheel spraying-configured electric conduction device

Abstract

The invention provides a plating bath cathode wheel spraying-configured electric conduction device which comprises a plating bath body. A set of upper and lower fluctuation electric conduction wheelsforming a fluctuation type wavy plating path are arranged in the plating bath body. First-grade upper and lower water blocking wheels are arranged on the left sides and the right sides of the upper and lower fluctuation electric conduction wheels correspondingly. An upper spraying pipe is arranged on the upper side of the upper fluctuation electric conduction wheel, and a lower spraying pipe is arranged on the lower side of the lower fluctuation electric conduction wheel. The upper spraying pipe and the lower spraying pipe are located on the corresponding positions of the outer sides of the upper fluctuation electric conduction wheel and the lower fluctuation electric conduction wheels and are used for spraying electric conduction liquid to the corresponding fluctuation electric conductionwheels. Gaps for a to-be-plated plating plate to pass through are formed between the corresponding upper wheels and lower wheels of the two sets of upper and lower water blocking wheels and one set of upper and lower fluctuation electric conduction wheels. The plating path of the to-be-plated plating plate is a fluctuation type wavy path. The plating bath cathode wheel spraying-configured electric conduction device has the beneficial effects that the electric conduction performance is good, and plating uniformity and plating current stability are good.
