Description

Technical Field

[0001] The utility model relates to the field of electroplating devices, in particular to an electroplating device for neodymium iron boron production. Background Technique

[0002] Neodymium iron boron (NdFeB) is a rare earth permanent magnet material composed of neodymium (Nd), iron (Fe) and boron (B) elements. It has quickly become one of the most important permanent magnet materials and has attracted attention due to its high magnetic energy product, high coercivity and high remanence. These properties make NdFeB very suitable for manufacturing high-performance permanent magnet motors, wind turbines, hard disk drives, electric vehicles and many other high-tech products. To extend the service life of NdFeB, during the production of NdFeB, it is usually necessary to use an electroplating device to add a coating to its surface to improve the corrosion resistance, mechanical strength and magnetic properties of the magnet. In the existing electroplating device, during use; since the electroplating solution and NdFeB are always in static contact in the electroplating chamber, it is easy to cause a sedimentation reaction of the electroplating solution, resulting in unstable temperature, current and electroplating quality of NdFeB during electroplating, thus causing problems such as uneven coating thickness, large roughness and poor corrosion resistance. Therefore, we propose an electroplating device for neodymium iron boron production to solve the problems mentioned above. Content of the Utility Model
