Problems solved by technology

[0009] The traditional process is complicated, and each process requires a large number of personnel to operate. With the progress of society, the problem of difficult labor is becoming more and more prominent. The instability of personnel will also affect the quality of products
The existing NdFeB nickel plating process has many processes, personnel shortage, and poor site environment. Therefore, production automation is required. Automation equipment not only ensures product quality and solves the problem of personnel shortage, but also is more environmentally friendly and the site is clearer. At the same time, the process needs to be carried out. Optimization and innovation

Abstract

The invention discloses an automatic nickel plating method for neodymium iron boron. The automatic nickel plating method for the neodymium iron boron comprises the following steps that feeding is conducted on a neodymium iron boron product to be plated with nickel, a signal is sent out after material loading, and an automatic nickel plating process starts automatically; first-time activation treatment is conducted; a bottom nickel layer is plated on the neodymium iron boron product obtained after the first-time activation treatment; first-time second-stage recovery is conducted to fully recover Ni ions; second-time activation treatment is conducted; copper layer plating is conducted; second-time second-stage recovery is conducted so as to fully recover Cu ions; third-time activation treatment is conducted; a semi-bright nickel layer is plated; third-time second-stage recovery is conducted so as to fully recovery Ni ions; fourth-time activation treatment is conducted; a bright nickel layer is plated; and fourth-time second-stage recovery is conducted to fully recover Ni ions, and the automatic nickel plating process is completed. According to the automatic nickel plating method forthe neodymium iron boron, the corrosion resistance of the product is improved.

Description

technical field [0001] The invention relates to the technical field of coating methods for NdFeB products, in particular to an automatic nickel plating method for NdFeB products. Background technique [0002] NdFeB electroplating adopts different electroplating processes according to the different use environments of the products, and the surface coatings are also divided into two categories, one is galvanized, which is used for conventional products; the other is nickel-plated, which is used for higher requirements. The product. There are also a few products that require other types of plating based on the needs of the whole machine, such as alloy plating, silver plating, etc. [0003] The traditional NdFeB nickel plating needs to be pre-plated with nickel, then thickened by copper plating, and then plated with bright nickel on the surface. [0004] ① Pre-plated nickel [0005] Nickel sulfate: 300g / L, pH value: 4.0~4.5, nickel chloride: 50g / L, temperature: 50~60℃, boric ...
