Problems solved by technology

[0003] In the production process of NdFeB magnets, NdFeB magnets need to be electroplated, and most of the existing NdFeB magnets are electroplated by barrel plating, but the existing electroplating devices cannot rotate during the electroplating process. The drum is continuously powered, and when the drum rotates, the NdFeB magnet in the drum will break away from the inner surface of the drum, resulting in the problem that continuous electroplating cannot be performed

Abstract

The invention discloses a continuous electroplating device for neodymium-iron-boron magnet production. The continuous electroplating device comprises an electroplating bath mechanism, a lifting mechanism and a roller mechanism, the roller mechanism is fixedly connected to the lifting mechanism, the lifting mechanism is fixedly installed on the electroplating bath mechanism, continuous power supplyto a rotating roller is achieved, and the problem that the neodymium-iron-boron magnet in the roller can be separated from the inner surface of the roller, so that continuous electroplating cannot beachieved is solved. The invention further discloses an implementation method of the continuous electroplating device for neodymium-iron-boron magnet production, when a roller assembly rotates, a conductive needle head makes contact with a copper circular ring on the side face of a reinforcing circular plate all the time, and the effect of continuously supplying power to a connecting copper sheetarranged in the shell of a roller shell is achieved; and a spring made of a copper material is arranged on the side surface of a cathode copper sheet, so that the contact area between the neodymium iron boron magnet and the cathode copper sheet is increased, and when the roller assembly rotates, the neodymium iron boron magnet in the roller shell can also be in continuous contact with the cathodecopper sheet, so that continuous electroplating is realized.

Description

technical field [0001] The invention relates to the technical field of NdFeB magnet production equipment, in particular to a continuous electroplating device for NdFeB magnet production and an implementation method thereof. Background technique [0002] Neodymium magnets, also known as NdFeB magnets, are tetragonal crystals formed of neodymium, iron, and boron. In 1982, Masato Sagawa of Sumitomo Special Metals discovered neodymium magnets. The magnetic energy product of this magnet is greater than that of the samarium cobalt magnet, and it was the material with the largest magnetic energy product in the world at that time. Later, Sumitomo Special Metals successfully developed the powder metallurgy method, and General Motors successfully developed the spin-spray smelting method, which was able to prepare NdFeB magnets. This kind of magnet is the second most magnetic permanent magnet after the absolute zero holmium magnet, and it is also the most commonly used rare earth mag...
