Description

Technical field:

[0001] The utility model relates to the technical field of NdFeB magnetization, in particular to an automatic NdFeB magnetization system. Background technology:

[0002] Sintered NdFeB permanent magnet materials have excellent magnetic properties and are widely used in electronics, power machinery, medical equipment, toys, packaging, hardware machinery, aerospace and other fields. The more common ones are permanent magnet motors, speakers, magnetic separators, computer disk drives, magnetic resonance imaging equipment and instruments, etc. Its main production process is: batching - smelting - powder making - pressing - sintering (sintered NdFeB) - processing - magnetization to make finished products. Among them, the magnetization wing plates of sintered NdFeB are divided into axial magnetization and radial magnetization, and the specific needs are determined according to actual needs. At present, our company produces a magnetic sheet with a C angle (that is, the whole is rectangular, with a right angle at the upper right corner). In order to ensure the simultaneous magnetization of multiple C-angle magnetic sheets, it is necessary to manually stand up all the C-angle magnetic sheets before magnetization. 20-50 C-angle magnetic sheets are grouped together and sent to the magnetizer for magnetization. It is required that the C angle of each group of C-angle magnetic sheets is in the same direction to ensure the consistency of product quality after magnetization and improve the product qualification rate. However, due to the small size of the C-angle magnetic sheet (5.02cm*4.4cm), it is not easy to operate manually. The operation is difficult and requires a large amount of manpower. The manual magnetization efficiency is 5,000 pieces per person per day, and the magnetization equipment works for a long time. Therefore, there are problems of high labor cost and low efficiency. In addition, manual sorting is prone to misoperation, which makes it impossible to guarantee the quality of the product. After the magnetization is completed, manual inspection is still required. For the situation where the C-angle direction is inconsistent, manual twisting and adjustment are still required, which is more cumbersome. Utility model content:
