Description

Technical Field

[0001] The utility model relates to the technical field of neodymium iron boron processing, in particular to a processing device for identifying neodymium iron boron blanks. Background Technique

[0002] In the application of neodymium iron boron magnets, the magnets are matched and adapted to the actual application assembly environment. For magnets used in certain specific environments, in order to obtain the optimal magnetic field, their magnetization orientation forms an angle with the length, width, and height reference planes. Sometimes, the magnet may include special-shaped features, which are the assembly characteristics of obliquely oriented special-shaped magnets. Such obliquely oriented magnets are usually processed from obliquely oriented blanks or normally oriented blanks through mechanical processing procedures such as slicing, special-shaped grinding, and end face grinding to obtain semi-finished products before electroplating. Among them, the special-shaped grinding process often processes the obliquely oriented angle and special-shaped features simultaneously. For determining the grinding position of the magnetic strip to be processed, the inspector needs to place the magnetic strip on the platform directly above the magnet with magnetism and observe with the naked eye to identify its position and posture in the magnetic field, so as to determine the grinding position. This method of magnetic testing operation has low recognition efficiency, high labor cost, and the magnetic strip is very easy to be magnetized, which will affect the subsequent processing process and product quality. If large-scale magnetic inspection equipment is used, the production cost will increase. Content of the Utility Model
