Description

Technical Field

[0001] The invention belongs to the technical field of nickel plating technology, and in particular relates to a nickel plating method for copper parts. Background Art

[0002] The method of plating a layer of nickel on metals or certain non-metals by electrolysis or chemical methods is called nickel plating. Nickel plating is divided into electroplating and chemical nickel plating. Electroplating nickel is an electrolyte composed of nickel salt (called main salt), conductive salt, pH buffer, and wetting agent. The anode is made of metal nickel and the cathode is the plated object. A direct current is passed through the electrolyte to deposit a uniform and dense nickel coating on the cathode (plate). Bright nickel is obtained from the plating solution with brightener, while dark nickel is obtained from the electrolyte without brightener. Chemical plating is also called electroless plating, or autocatalytic plating. It is a process in which metal ions in an aqueous solution are reduced by a reducing agent under certain conditions and precipitated onto the surface of a solid substrate.

[0003] The Chinese invention patent with publication number CN109267115A discloses a method for nickel plating copper parts. After the cathode electrolytic degreasing, an anodic electrolytic degreasing is added, which effectively solves the probability of the occurrence of mottled surfaces on the bayonet of high-demand electroplated parts. The traditional double-layer nickel (Watt nickel + bright nickel) is changed to a single-layer bright nickel, and the required appearance and performance requirements are achieved with one process tank. The single-layer nickel electroplating method is adopted to eliminate the bonding rate problem between the double-layer nickel, thereby improving the qualified rate of high-demand appearance parts.

Summary of the invention

[0006] The present invention provides a method for nickel plating copper parts, aiming to solve the problem that the current degreasing method can complete the degreasing of parts, but it is inconvenient to transfer the parts from one process to another process, and it is also impossible to accelerate the ratio efficiency of solutions in different processes.

When the parts are immersed in the gasoline solution, a large amount of grease can be dissolved and removed quickly through stirring by the mixer 15 or manual washing and degreasing. The trichloroethylene treatment box 4 contains a solution of liquid trichloroethylene 43. When the heating device 42 in the trichloroethylene treatment box 4 works, the liquid trichloroethylene 43 can be turned into steam. When the parts are placed in the trichloroethylene steam, the grease on the workpiece is dissolved by the liquid condensed when the steam contacts the workpiece. This steam cleaning will not pollute the workpiece because the degreasing workpiece contacts clean trichloroethylene. The interior of the anhydrous ethanol box 5 contains anhydrous ethanol, which can remove the oil on the parts again. The magnesium carbonate box 6 contains magnesium carbonate solution, which can be used to deoil the parts again.

[0046] Furthermore, the transfer mechanism 1 includes a base 11, and forward and backward moving components 12 are installed on the top of both ends of the base 11.

When the electromagnet is energized, it can generate magnetic force and then attract the material frame 16. This fixing method makes it easy to place the material frame 16 in the gasoline treatment box 3, and then allow the mixer 15 to enter the gasoline treatment box 3 and stir the gasoline solution in the gasoline treatment box 3, so as to quickly dissolve a large amount of grease on the parts.

[0050] Furthermore, the skateboard 143 has two guide blocks 144, and the two guide blocks 144 are fixedly connected to the skateboard 143.
