Description

Swinging device for electroplating hanger Technical Field The invention relates to the technical field of electroplating equipment, in particular to a swinging device for an electroplating rack. Background Electroplating means that plating solution for pre-plating metal is filled in a plating tank, then the substrate metal to be plated is used as a cathode to be suspended and immersed in the plating solution through a hanger, and cations of the pre-plating metal in the plating solution are deposited on the surface of the substrate metal through the action of electrolysis, so that a surface processing method of a plating layer is formed. For example, in the current electroplating of PCB, most of the hangers clamp the PCB together to enable the PCB to be electroplated in an electroplating cylinder, bubbles and gas are easy to adhere to the surface of the PCB and enter the electroplating cylinder, the bubbles and the gas are difficult to be discharged, and the bubbles are not conductive in the electroplating process, so that the metal deposition is not obtained at the positions of the surface of the PCB, on which the bubbles are adhered, so that the electroplating of the surface of an electroplated workpiece is uneven.
