Automatic magnetizing system of sintered neodymium-iron-boron permanent magnet material

Abstract

The invention discloses an automatic magnetizing system of a sintered neodymium-iron-boron permanent magnet material. The system comprises a feeding device, an arraying device, a magnetizing coil assembly, a material pushing device and a material receiving box, wherein the feeding device is provided with a first arraying rail; the arraying device is provided with a second arraying rail which is connected with the first arraying rail; the magnetizing coil assembly comprises a magnetizing coil and a magnetizing coil rail; the material pushing device is arranged at the tail end of the magnetizingcoil rail; the material receiving box is connected with the magnetizing coil rail. The system can conduct magnetization treatment on small-size to-be-magnetized workpieces on a large scale on the automatic magnetization treatment production line. Two arraying operations are conducted in a vibration feeding disc and the arraying device, mutual collision among workpieces is avoided, the collision among the workpieces is reduced, therefore the reject rate of appearance sizes of workpiece products can be greatly reduced after the magnetization treatment is completed. Due to the fact that the arrangement of to-be-magnetized workpieces is regular, the problem of insufficient magnetizing in the magnetizing process can be prevented.

Description

technical field [0001] The invention relates to the technical field of magnetic material production and manufacturing, and more specifically relates to an automatic magnetization system for sintered NdFeB permanent magnet materials. Background technique [0002] In recent years, the market demand and industrial scale of NdFeB permanent magnet materials are developing rapidly, and its application fields cover many industries such as modern industrial motors, microelectronic motors, and new energy motors. However, due to the large demand and different types of NdFeB, after the magnets are magnetized and arranged manually, it is necessary to manually operate the magnetizer to complete the magnetization operation. [0003] At present, most manufacturers mainly use manual alignment and manual operation of magnetizers to magnetize NdFeB finished products. Under the environment of increasing market demand and rising labor costs, magnetization Magnetic production efficiency and cap...

Problems solved by technology

However, for the magnetization of small-sized magnet workpieces, due to the small size and large magnetic force of the workpiece, if the existing automatic production line is used directly, the workpiece will be unsaturated, magnetized, mixed, and damaged due to the small size of the material. and other damage, resulting in a large number of defective products that cannot be used after production
