Problems solved by technology

[0002] In the field of rare earth metallurgical processing, at present, sintered NdFeB magnets are permanent magnets with the widest application, the largest output, and the strongest comprehensive magnetic properties. Among them, the proportion of manual work in the molding process is large, the production efficiency is low, the waste of materials is serious, the quality control is difficult, and the phenomenon of missing edges and corners occurs from time to time, and the materials in the process are in powder state, so it is not suitable for long-term storage. Some molding processes have become a major obstacle to reducing production costs and improving product quality

Embodiment 1

[0023] figure 1 It is a schematic diagram of the overall structure of an automatic removal device for NdFeB prefabricated compacts of the present invention. Such as figure 1 As shown, the device of the present invention includes a vacuum adsorption unit, a prefabricated compact moving protection channel 5, a prefabricated compact receiving platform 6, a PLC control circuit, and a servo unit (not shown), wherein the vacuum adsorption unit is used for removing NdFeB prefabricated compact, which includes a gas supply unit (not shown, a nitrogen supply unit in this embodiment), a gas channel 1 (a nitrogen channel in this embodiment), a vacuum generating unit 2, a powder collector 3 and sucker4. The gas supply unit communicates with the gas channel 1 and is used to supply inert gas (such as nitrogen) to the gas channel to protect the NdFeB prefabricated compact. The vacuum generating unit 2 communicates with the gas channel 1 and is used to form negative pressure in the gas chan...

Embodiment 2

[0029] Except that the thickness of the sponge in embodiment 1 is replaced by 15mm by 10mm, all the other components and parameters are the same as embodiment 1.

Embodiment 3

[0031] Except that the taper angle α in embodiment 1 is replaced by 105° from 135°, other components and parameters are the same as in embodiment 1.

Abstract

The invention discloses an automatic removal device for NdFeB prefabricated compacts, which includes a vacuum adsorption unit, a prefabricated compact moving protection channel, a prefabricated compact receiving platform, a PLC control circuit and a servo unit, wherein the vacuum adsorption unit is used for It is used to remove NdFeB prefabricated compacts; the prefabricated compact moving protection channel is used to transport the removed NdFeB prefabricated compacts; the prefabricated compact receiving platform is used to accept the transferred NdFeB prefabricated compacts. It is connected with the moving protection channel of the prefabricated compact; the PLC control circuit and the servo unit are used to control the vacuum adsorption unit to remove the NdFeB prefabricated compact. The device of the invention can not only realize automation to improve production efficiency, but also prevent the occurrence of missing edges and corners of raw materials during conventional manual operations.

Description

technical field [0001] The invention relates to an automatic removal device for a NdFeB prefabricated compact, and the device belongs to the field of rare earth metallurgical processing. Background technique [0002] In the field of rare earth metallurgical processing, at present, sintered NdFeB magnets are permanent magnets with the widest application, the largest output, and the strongest comprehensive magnetic properties. Among them, the proportion of manual work in the molding process is large, the production efficiency is low, the waste of materials is serious, the quality control is difficult, and the phenomenon of missing edges and corners occurs from time to time, and the materials in the process are in powder state, which is not suitable for long-term storage. Now Some molding processes have become a major obstacle to reducing production costs and improving product quality. [0003] Therefore, there is an urgent need for an automatic removal device for NdFeB prefab...
