Description

Technical Field

[0001] The invention relates to the technical field of electroplating, and in particular to a neodymium iron boron magnet electroplating system. Background Art

[0002] With the rapid development of rare earth NdFeB permanent magnet materials, the problems in NdFeB electroplating have become increasingly apparent, becoming an important factor restricting its development. NdFeB magnets are produced using powder metallurgy technology, so the actual density of the material cannot reach the theoretical density. There are tiny pores and voids inside, which are easy to absorb oxygen in the atmosphere to oxidize rare earth elements and destroy alloy components. After the material is corroded or the components are destroyed, the magnetic properties will decay and even be lost over time, thus affecting the performance and life of the whole machine, so strict anti-corrosion treatment must be carried out before use.

[0003] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to adhere a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance and enhancing aesthetics.

[0004] When the existing electroplating device is in use, a liquid pump is usually used to drive the flow of the plating liquid, thereby making the plating liquid more uniform and allowing the plated parts to have a greater degree of contact with the plating liquid to improve the electroplating effect. However, when electroplating is performed in this way, the circulation efficiency of the plating liquid around the plated parts is limited and the optimal electroplating effect cannot be achieved.
