Abstract

The invention relates to an electroplating process of a neodymium iron boron magnet, electroplating equipment is used in the electroplating process, the electroplating equipment comprises an electroplating pool, a placing frame capable of being placed in the electroplating pool, and a weight detection mechanism used for detecting the weight of the magnet in electroplating liquid before and after electroplating, and the electroplating process comprises the following steps: S1, carrying out electroplating; the pretreated magnet is placed on the placing frame; s2, placing the shelf in an electroplating tank; s3, electroplating the magnet under the action of current; s4, a weight detection mechanism monitors the weight of the magnet before and after electroplating in real time and sends a signal to the controller; s5, the controller passes through a formula (h is the thickness of the plating layer; delta m is the weight of the plating layer; rho is the plating layer density; and S: the surface area of the magnet), the real-time thickness of the plating layer is calculated until the plating layer reaches the preset thickness, and the real-time weight of the plating layer is monitored through the weight detection mechanism, so that the real-time thickness of the plating layer is calculated, the increase and decrease of the current density are controlled, and the electroplating efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of magnet preparation, in particular to an electroplating process of an NdFeB magnet. Background technique [0002] Permanent magnets are hard magnets, magnets that can maintain their magnetism for a long time, and are not easy to lose their magnetization or be magnetized. Therefore, whether in industrial production or in daily life, hard magnets are one of the most commonly used strong materials. Hard magnets can be divided into natural magnets and artificial magnets. Artificial magnets mean that by synthesizing alloys of different materials, the same effect as natural magnets (magnets) can be achieved, and the magnetic force can also be improved. With the emergence of rare earth permanent magnets in the 1960s, it opened up a new era for the application of magnets. The first generation of samarium cobalt permanent magnet SmCo and the second generation of precipitation hardening samarium cobalt permanent ma...
