Description

technical field [0001] The invention relates to the field of NdFeB permanent magnet production, in particular to a method and equipment for magnetizing and collecting NdFeB permanent magnets. Background technique [0002] NdFeB permanent magnet is an energy storage material that can generate a constant magnetic field in a certain space. Due to its extremely high coercive force and magnetic energy product, especially in the environment of 20 ° C ~ 150 ° C compared to other permanent magnets, the NdFeB permanent magnet material has won a lot of attention in various fields, especially in modern high-tech fields. widely used. Before the NdFeB magnet is subjected to magnetic detection or assembled into a device with a certain function, it needs to be magnetized in a magnetizer to become magnetic. Before magnetization, it is necessary to collect the unmagnetized NdFeB permanent magnets into the magnetization frame, and then place the NdFeB permanent magnets in the magnetization ...

AI Technical Summary

Problems solved by technology

[0004] The prior art has the following deficiencies: 1. When loading NdFeB permanent magnets, the NdFeB permanent magnets are first fed to the collecting tray groove of the feeding collection tray through the vibrating tray feeding mechanism, and then the NdFeB permanent magnets in the moving mechanism are moved. The movement of the moving cylinder drives multiple suction heads down to absorb and move the NdFeB permanent magnets in the groove of the collecting tray; while the moving cylinder is controlled pneumatically, when the compressed gas is insufficient or the gas source is cut off, the moving cylinder will provide power due to the loss of compressed gas It will automatically move down to absorb the NdFeB permanent magnet in the groove of the collecting tray; thus affecting the accuracy of the feeding action of the feeding device

3. When moving the NdFeB permanent magnets, generally the arranged NdFeB permanent magnets are manually moved to the material distribution mechanism, and the NdFeB permanent magnets after the materials are staggered in the material distribution mechanism are manually moved to the In the magnetizing rack; and the number of NdFeB permanent magnets is large, it takes a lot of time to manually move the NdFeB permanent magnets, which reduces the moving efficiency of the NdFeB permanent magnets; at the same time, manually moving the NdFeB permanent magnets is not conducive to the moving process Combined with other devices, it is not conducive to the automatic processing of the entire equipment

5. When dividing and moving NdFeB permanent magnets, the material dividing process and moving process of NdFeB permanent magnets are separated; that is, first use the material dividing mechanism to divide the NdFeB permanent magnets, and then manually Move the divided NdFeB permanent magnets to the magnetizing frame; and when the material dividing process and the moving process of the NdFeB permanent magnets are separated, it is necessary to manually move the NdFeB permanent magnets from the material dividing mechanism to the magnetizing frame. position, which increases the manual working time; at the same time, when the distance between the distributing mechanism and the magnetizing frame is far away, the time required to move the NdFeB permanent magnet will also increase, which is not conducive to the NdFeB permanent magnet after distributing. fast moving
