[0002] Neodymium iron boron should be neodymium iron boron, also known as neodymium magnet. It is a tetragonal crystal formed by neodymium, iron, and boron. Neodymium iron boron magnet is the permanent magnet with magnetic property second only to holmium magnet at absolute zero temperature nowadays, and it is also the most commonly used rare earth magnet, with high magnetic performance and good mechanical properties. Neodymium iron boron needs to go through a series of processings to meet the specific requirements of different application fields. In the processing process, in order to improve the durability of neodymium iron boron, it is usually necessary to perform pre-treatments such as cleaning and grinding on the surface of sintered neodymium iron boron, and then coat a protective coating. Most of the existing surface coating devices are unidirectional coating. During the coating process of neodymium iron boron, the thickness of the coating is uneven, making it difficult to ensure consistent quality and affecting the magnetic properties of neodymium iron boron.
