Anode shielding device for tin plating bath

Technical Field

The invention relates to the technical field of anode shielding devices of plating tanks, in particular to an anode shielding device for a tin plating tank.

Background

During electroplating, plating metal or other insoluble materials are used as an anode, a workpiece to be plated is used as a cathode, and cations of the plating metal are reduced on the surface of the workpiece to be plated to form a plating layer. In order to eliminate the interference of other cations and make the coating uniform and firm, a solution containing the metal cations of the coating is used as an electroplating solution to keep the concentration of the metal cations of the coating constant. The purpose of electroplating is to plate a metal coating on a substrate, altering the surface properties or dimensions of the substrate. The electroplating can enhance the corrosion resistance of the metal (the plating metal is mostly corrosion-resistant metal), increase the hardness, prevent abrasion, improve the conductivity, the smoothness, the heat resistance and the surface beauty.

At present, when most of copper bars are tinned or silvered, a dip plating method is mainly used, and because a workpiece to be plated in the dip plating method needs to be dipped in a plating tank, the surface of the workpiece to be plated, which is in contact with electroplating solution, is electroplated, and local electroplating cannot be carried out; the plated area of the copper bar is generally a part at two ends or in the middle, if the part needs to be plated, a coating or an insulating layer is required to be coated on the workpiece to be plated, the part which is not plated can be coated by the insulating layer, so that the part of the workpiece to be plated is plated, and after the part is plated, a stripping process is required to strip the coating or the insulating layer, so that the part plating can be completely finished.

The scheme increases the processing procedures, reduces the processing efficiency and improves the processing cost during local electroplating, so the invention of the anode shielding device for the tinning plating bath is urgently needed.
