Nickel plating production line and electroplating process thereof

Abstract

The invention relates to a nickel plating production line and an electroplating process thereof. The nickel plating production line includes an electroplating treatment system, the electroplating treatment system includes an oil removing tank, a steam tank, a first water washing tank, an activated bath, a second water washing tank, an impact nickel tank, an electroplating tank, a passivation tank,a third water washing tank and a drying tank which are sequentially arranged in the length direction of a plant; a transportation device for transporting workpieces is arranged above the electroplating treatment system, the transportation device is connected with a PLC control cabinet, the transportation device includes a first slideway and a second slideway which are in parallel arrangement, andthe first slideway and the second slideway are all arranged in the length direction of the plant; and the first slideway and the second slideway are both slidably connected with lifting sliding columns, supporting beams are arranged on the lifting sliding columns in the vertical direction, and electroplating hangers are connected to the end, away from the lifting sliding columns, of the supporting beams. The oil stains and impurities on the surfaces of the workpieces can be effectively and conveniently removed, the pretreatment effect of the workpieces is further improved, and the effect of improving the electroplating processing quality of the workpieces is further achieved.

Description

technical field [0001] The invention relates to the technical field of electroplating equipment, in particular to a nickel plating production line and an electroplating process thereof. Background technique [0002] The method of plating a layer of nickel on metal or some non-metal by electrolysis or chemical method is called nickel plating. Nickel plating is divided into electroplating nickel plating and chemical nickel plating. Nickel electroplating is in an electrolyte composed of nickel salt (called main salt), conductive salt, pH buffer, and wetting agent. The anode uses metallic nickel, and the cathode is the plated part. Deposit a uniform and dense nickel coating. The electroplating process is roughly the same, generally including three main stages: pre-plating pretreatment, electroplating and post-plating treatment. [0003] The Chinese patent with the publication number CN1107350-5563A discloses an electroplating process, which includes the following steps: S1, c...

AI Technical Summary

Problems solved by technology

[0004] In the prior art scheme mentioned above, the pretreatment process of electroplated workpieces only simply uses hot water immersion to degrease and pickling activation. The removal of organic impurities, while the grease and organic debris on the surface of the workpiece will affect the activation of the pickling solution on the surface of the workpiece, thereby affecting the combination of the coating and the workpiece. The residual grease and organic debris on the surface of the workpiece will also easily cause the surface of the workpiece to Pinholes and burrs may occur, and may cause peeling of the coating, affecting the quality of the electroplating process of the workpiece
