Automatic nickel-copper-nickel electroplating device for NdFeB products

Abstract

The invention discloses a device for automatically electroplating nickel-copper-nickel on a neodymium iron boron product. The device comprises a liquid receiving device, a two-stage lifting device anda roller return device, wherein the liquid receiving device is fixed at the bottom of a self-propelled trolley, moves along with the self-propelled trolley according to a process, and is provided with a telescopic liquid receiving plate, the two-stage lifting device lifts a roller with a plated member, is fixed on the self-propelled trolley, and moves along with the self-propelled trolley according to the process, a second-stage lifting device is connected to a first-stage sliding mechanism of a first-stage lifting device, the bottom end of the second-stage lifting device is provided with a hanging claw; the roller return device is hung upside down under a steel structure frame of the device for automatically electroplating nickel-copper / nickel, and is located in a maintenance passage between two support frames, a return trolley drives a roller frame to automatically return to a loading station, and the roller frame is downwards connected to a roller storage rack. The two-line parallel automatic operation of the device provided by the invention greatly improves the electroplating efficiency, effectively prevents the problem of plating solution leakage, and an empty roller is automatically returned to achieve automatic recycling of the roller.

Description

technical field [0001] The invention relates to the field of a surface treatment device for NdFeB products. More specifically, the present invention relates to an automatic nickel-copper-nickel electroplating device for NdFeB products. Background technique [0002] As a kind of rare earth permanent magnet material, NdFeB has extremely high magnetic energy product and coercive force, and has the advantages of high energy density. It is widely used in modern industry and electronic technology, making instruments, electroacoustic motors, Miniaturization, weight reduction, and thinning of equipment such as magnetic separation and magnetization become possible. [0003] There are many methods for surface treatment of NdFeB products, nickel-copper-nickel plating is one of them, to improve the corrosion resistance of NdFeB products, and at the same time, it has no shielding effect on the magnetism of NdFeB products, and has good uniformity , The corner effect, the coating has lit...

AI Technical Summary

Problems solved by technology

Before electroplating nickel-copper-nickel for NdFeB products, put the cleaned workpiece into the drum, and then put the drum into the electroplating tank for electroplating operation. Before this, such electroplating process was all manual work, which was extremely cumbersome , and it takes a lot of manpower and material resources, the production efficiency is low, and after the electroplating is completed, because the liquid contact device cannot go down with the electroplating process, the problem of the electroplating solution stringing cannot be solved during automatic operation, and the quality of the coating cannot be guaranteed. After the electroplating is completed, The empty drum for unloading the plated parts needs to be manually moved back to the loading station, which cannot realize the automatic operation of the whole process
