Abstract

The invention discloses a full-automatic galvanizing process for neodymium iron boron. The process comprises the following steps of: feeding a galvanized neodymium iron boron product, and starting anautomatic galvanizing process when a material is loaded and a signal is given; and carrying out automatic pickling for 30s by 2%HNO3 solution; carrying out ash removal to the product after automatic pickling, wherein the ash removal is carried out by roller ash removal; first secondary backflow washing is carried out to the product after ash removal; a first secondary backflow washing product is electrogalvanized, and the electroplating zinc uses potassium chloride electroplating solution to obtain the galvanized neodymium iron boron product; the galvanized neodymium iron boron product is polished; automatic passivation treatment is carried out to the polished neodymium iron boron product; and a second secondary backflow washing is carried out to a passivation product.

Description

Technical field [0001] The invention relates to the technical field of electro-galvanization, in particular to a neodymium-iron-boron automatic galvanizing process. Background technique [0002] Neodymium iron boron magnets are tetragonal crystals formed by neodymium, iron and boron. Neodymium iron boron magnets are permanent magnets with magnetic properties second only to absolute zero holmium magnets, and they are also the most commonly used rare earth magnets. NdFeB magnets are widely used in electronic products, such as hard drives, mobile phones, earphones, and battery-powered tools. NdFeB electroplating adopts different electroplating processes according to the use environment of the product. The surface coating is also divided into two categories, one is galvanized, used for conventional products; the other is nickel-plated, used for higher requirements The product. There are also a few products that require other plating types, such as alloy plating, silver plating, et...
