Device for workpiece cleaning

Abstract

A workpiece cleaning device, comprising a frame, a rotating mechanism, and an ultrasonic assembly. The ultrasonic assembly is provided with an element, and the ultrasonic assembly is arranged inside the rotating mechanism. There is an angle between 0° and 80°. The ultrasonic component is built in the center of the rotating mechanism, and the proper position and angle of the ultrasonic component installation can be calculated to improve the ultrasonic cleaning effect, so as to ensure that the NdFeB magnet is cleaned by ultrasonic cleaning in the pretreatment. The invention can realize the automatic and high-efficiency cleaning of the NdFeB magnets, and solves the problems of unstable manual cleaning, unclean cleaning and the like in the prior art. The invention adopts mechanized cleaning operation, the pretreatment of NdFeB magnets can be automated, the process is solidified, the cleaning effect is high and the cleaning quality is stable, the number of labor is greatly reduced, and the labor force is liberated.

Description

Technical field [0001] The present invention relates to the technical field of material surface treatment equipment, and more particularly to a workpiece cleaning device. Background technique [0002] The NdFeB magnet is mainly composed of the main phase, the rich phase and the boron-rich phase. The rich is generally distributed at the grain boundary. Since the activity of neodymium is strong, there is a low corrosion potential of the rich, which is prone to corrosion. In addition, the NdFe boron magnet material also has a structural feature of surface loose porous. [0003] Because the NdFeB material is a porous structure, it passes through a series of processing processes, there may be rust, oxidized skin or the like before electroplating, so it is necessary to have a strict pretreatment to wash. The pretreatment cleaning operation is as follows: first wash the corrosion of the NdFe boron material, the oxide, etc. of the surface of the NdFe boron material, and then cleaned the ...

AI Technical Summary

Problems solved by technology

Although drum cleaning liberates the labor force, there is a problem of incomplete material cleaning in drum cleaning, which makes it difficult to promote and apply mechanized cleaning operations on a large scale

[0006] Through practical research and analysis, the reasons for the incomplete mechanized cleaning are: 1. The material is not cleaned uniformly in the cleaning processes such as pickling, water washing, and activation. Because the drum is cleaned in the above liquid, the liquid is not exchanged sufficiently inside and outside the drum and the washed-off Impurities cannot be discharged from the drum in time, making it difficult to clean the material evenly; 2. The NdFeB residue washed off after pickling hangs on the surface of the NdFeB material or even exists in the pores on the surface of the material. During the ultrasonic treatment, these impurities, The ultrasonic generator is generally installed in the tank of the support frame outside the drum. The distance between the ultrasonic generator and the workpiece is relatively long, which weakens the ultrasonic cleaning effect and makes it difficult to clean NdFeB.
