Description

technical field [0001] The invention relates to the technical field of NdFeB magnet processing, in particular to a NdFeB magnet processing device. Background technique [0002] NdFeB magnet is a tetragonal crystal formed by neodymium, iron and boron (Nd2Fe14B). The magnetic energy product (BHmax) of this magnet is greater than that of the samarium cobalt magnet, and it was the material with the largest magnetic energy product in the world at that time. This kind of magnet is the second most magnetic permanent magnet after the absolute zero holmium magnet, and it is also the most commonly used rare earth magnet. NdFeB magnets are widely used in electronic products, such as hard drives, mobile phones, earphones, and battery-powered tools.

Problems solved by technology

[0003] During the processing of cylindrical NdFeB magnets, a feeding device is required. The existing feeding device has poor stability and is prone to failure during the feeding process of circular structure magnets, resulting in the failure of NdFeB magnets. The feeding process of blanks is interrupted, which reduces production efficiency and increases production costs. At the same time, some special devices for feeding NdFeB magnet blanks have high costs and cannot meet the needs

[0004] In addition, during the processing of NdFeB magnet blanks, the surface of the magnet needs to be processed to meet the needs of customers or equipment, that is, the external dimensions of the magnet need to be ground. The blank is manually transferred to the feeding port of the grinding machine, the production efficiency is low, and it cannot meet the needs; in addition, when the existing grinding machine is used, the material enters the processing station. Since the material is in a static state, when it is in contact with the rotating abrasive roller , it is easy to cause jumping, resulting in low yield rate of polished products and easy damage to the device; staff often need to manually move the material to be polished at the inlet of the processing station to make it rotate, this method is not only low in production efficiency; at the same time, the existing The position of the abrasive roller and the motor that drives the abrasive roller in the grinding device is generally fixed, and the friction gap between the friction roller and the material cannot be adjusted. Between the wires, the fixed structure design of the abrasive roller and the motor makes it inconvenient to disassemble and maintain, resulting in a reduction in the service life of the device
