An automatic marking device for cylindrical NdFeB magnets

Abstract

The invention discloses an automatic marking device for cylindrical NdFeB magnets, which comprises a support table, a vibrating feeding tray, a feeding hose, a first optical fiber sensor, a guide channel, a rotating disc, a supporting disc, a workbench, a driver, and a spray nozzle. coding machine, feeding pipe, blowing pipe and receiving hose for packaging cylindrical NdFeB magnets; the advantage is that the cylindrical NdFeB magnets can be transported after being erected, so that the existing assembly line can be used Automatic coding marking technology realizes polarity marking, high marking efficiency, low marking cost, suitable for mass production, uniform marking, high consistency of cylindrical NdFeB magnets, low labor intensity of employees, and After marking, the cylindrical NdFeB magnets can be automatically packaged, and the orientation of the cylindrical NdFeB magnets will not be reversed, so as to ensure the actual polarity and marked polarity of the cylindrical NdFeB magnets after subsequent magnetization Similarly, improve the production pass rate of cylindrical NdFeB magnets.

Description

technical field [0001] The invention relates to an automatic marking device, in particular to an automatic marking device for cylindrical neodymium iron boron magnets. Background technique [0002] NdFeB magnets have excellent magnetic properties and high cost performance, and have been widely used in modern industry, electronic technology, information technology, nuclear magnetic resonance, wind power generation, servo motors and new energy vehicles and other fields. At the same time, the demand for NdFeB magnets is also increasing. In order to ensure the demand of NdFeB magnets, it is necessary to improve its production efficiency. Therefore, the current production process of NdFeB magnets has put forward very high requirements. [0003] In order to facilitate the installation of NdFeB magnets by customers in the later stage, NdFeB magnet manufacturers need to mark the polarity on the end face of NdFeB magnets during the production process. For NdFeB magnets of conventio...

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
