Plating limit device, plating equipment using same and plating method using same

Abstract

The invention discloses a plating limit device, plating equipment using the same and a plating method using the same. The plating limit device is used for limiting a moving zipper in a plating process and comprises a plating cathode and a tensioning mechanism, wherein the top face of the plating cathode is provided with an opening, cloth belts of the zipper runs through the opening of the plating cathode; and the tensioning mechanism is used for applying a tensile force toward the plating cathode onto the zipper to allow the bottom of zipper teeth on the cloth belts of the zipper to be pressed against and connected with two sides of the opening of the plating cathode and to be electrically connected with the plating cathode. The plating equipment using the plating limit device and the plating method using the plating limit device have the advantages of high plating quality and high plating efficiency.

Description

technical field [0001] The invention relates to an electroplating limiting device, electroplating equipment and an electroplating method using the device, in particular to an electroplating limiting device for electroplating zippers, an electroplating equipment and an electroplating method using the limiting device. Background technique [0002] At present, in order to enhance the aesthetics and improve the wear resistance and corrosion resistance, the industry usually uses metal deposition to plate the surface of the upper chain teeth of the zipper chain belt. Commonly used metal deposition methods are electroless plating and electroplating. When electroless plating is used for plating, a zipper with good wear resistance cannot be obtained because the plating layer is not dense. When electroplating is used for plating, although the obtained plating layer is dense enough, how to energize the chain elements arranged at intervals on the non-conductive zipper chain tape has be...

AI Technical Summary

Problems solved by technology

[0003] In the above electroplating process, the zipper strip must be bent to contact the surface of the electroplating guide wheel, and the zipper strip does not have the ability to bend arbitrarily due to the existence of metal elements arranged at intervals

Therefore, during continuous electroplating, it is impossible to ensure that every chain tooth on the zipper is in effective electrical contact with these electroplated guide wheels, thereby affecting the quality of the electroplated zipper

Since these electroplating guide wheels directly contact with the side of the chain teeth of the zipper strip during electroplating, the electroplating reaction interface at this position is destroyed, and ...
