Description

technical field [0001] The invention relates to the field of NdFeB permanent magnet production, in particular to a NdFeB permanent magnet material distributing device, a material distributing method and a material distributing and moving device. 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 p...

AI Technical Summary

Problems solved by technology

[0004] The prior art has the following deficiencies: 1. When distributing multiple NdFeB permanent magnets, first move the continuously arranged multiple NdFeB permanent magnets to the groove of the distributing mechanism composed of a fixed plate and a movable plate , then the movable plate is staggered relative to the fixed plate to drive the movement of multiple NdFeB permanent magnets on the movable plate to complete the material distribution; while the multiple NdFeB permanent magnets are arranged continuously before the staggered material distribution, adjacent NdFeB permanent magnets The sides of the magnets are in contact with each other; when distributing materials to adjacent NdFeB permanent magnets, part of the NdFeB permanent magnets will move due to the friction of the side of the adjacent NdFeB permanent magnets; while the NdFeB permanent magnets in the distribution mechanism There is an opening above the groove where the boron permanent magnet is located. When the friction force on the side of the adjacent NdFeB permanent magnet is large, the stressed NdFeB permanent magnet will slide out along the opening above the groove; thus making the NdFeB permanent magnet The permanent magnet is offset relative to the groove, which affects the material distribution accuracy of the NdFeB permanent magnet

2. 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

4. 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
