Description

Technical Field

[0001] The utility model relates to an electroplating nickel bath, in particular to an electroplating nickel anode shielding device. Background Art

[0002] In an electroplating production line, in order to deposit a uniform and dense nickel coating on a cathode (workpiece to be plated), metallic nickel for the anode needs to be added to the plating solution, and a direct current is applied to the cathode workpiece, so as to obtain the required nickel coating. Although such equipment can achieve nickel plating processing, at the edges and tips of the cathode (workpiece to be plated), there are often more electric lines concentrated, and this phenomenon is called the tip effect or edge effect. The edge of the cathode (workpiece to be plated) surface has a thicker coating due to the denser distribution of equipotential planes, and even burrs, burning and other phenomena may occur at the tip or edge of the cathode (workpiece to be plated). Correspondingly, the coating in the middle area of the workpiece to be plated is thinner due to the sparser distribution of equipotential planes. In the prior art, in order to solve the edge effect, a shielding plate is generally added to the electroplating nickel bath, and the shielding plate is fixed in the electroplating nickel bath. The relative position change between the anode and the workpiece to be plated due to the mechanical swing of the workpiece to be plated in the electroplating bath will cause uneven current distribution. For electroplating nickel baths with workpieces of various sizes or mechanical swings that cause changes in the relative positions of the anode and cathode, this fixed shielding plate can no longer meet the shielding requirements, and it is also not convenient to replace and maintain separately and quickly. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an electroplating nickel anode shielding device that can make the coating of the workpiece uniform and is convenient for checking and replacing the shielding plate in view of the deficiencies of the prior art.
