Description

Technical field[0001]The present invention relates to an automatic marking apparatus, and more particularly to an automatic marking apparatus for cylindrical NdFeB magnetic steel.Background technique[0002]NdFeB magnetic steel has excellent magnetic properties and extremely high cost performance, which has been widely used in modern industries, electronic technology, information technology, nuclear magnetic resonance, wind power, servo motors, and new energy vehicles. At the same time, the demand for NdFeB magnetic steel is also growing. In order to ensure the demand of NdFeB magnetic steel, it is necessary to improve its production efficiency. Therefore, there is currently high requirements for the production process of NdFeB magnetic steel.[0003]In order to facilitate the installation of neodymium iron boron magnetic steel, NdFeB magnetic steel manufacturers need to mark their polarity in the end face of NdFeB magnetic steel during production process. For conventional shapes that c...

Problems solved by technology

However, the manual single-piece marking method not only has low marking efficiency and high marking cost, it is not suitable for mass production, and the labor intensity of employees is high, and the markings made by different employees are also quite different, so that the final cylindrical NdFeB magnets The consistency is poor. In addition, the marked cylindrical NdFeB magnets need to be packed and transferred to the subsequent magnetization process for magnetization. Therefore, the marked cylindrical NdFeB magnets need to be For packaging, the manual arrangement is still used in the packaging process, that is, after each cylindrical NdFeB magnet is marked, the cylindrical NdFeB magnet needs to be loaded into the receiving hose according to a specific orientation. During this packaging process, it is very easy for employees to reverse the front and rear orientations of the cylindrical NdFeB magnets. Once they are reversed, the actual polarity of the cylindrical NdFeB magnets after subsequent magnetization will be opposite to the marked polarity, and eventually Resulting in a decline in the production pass rate of cylindrical NdFeB magnets
