Description
Technical Field
The invention relates to the technical field of magnet production, in particular to a magnet surface treatment device.
Background
Magnets produced from permanent magnet materials such as neodymium iron boron are very easy to oxidize and corrode, so most magnets need to be subjected to a final surface treatment process before leaving a factory so as to achieve the purpose of corrosion resistance, and the surface treatment of the magnets also has the following purposes: loose magnetic particles on the surface of the magnet are removed through surface treatment so as to prevent the magnetic particles from influencing the magnetic function or damaging a magnetic system and achieve the aim of smooth and clean surface; the surface protective coating can protect the magnet (especially the edge) from falling off of magnetic particles caused by mechanical stress during assembly or operation.
The organic coating of the neodymium iron boron permanent magnet is usually made of epoxy resin or resin paint such as acrylic acid, polyamide and the like, wherein the epoxy resin has the best water resistance and chemical corrosion resistance, but has higher cost. The organic coating is usually applied by cathodic electrophoresis or spraying. However, the spraying process is mainly applied to products with regular magnet shapes and low corrosion prevention requirements, and therefore, the electrophoresis process is a main mode for coating the surface protective layer of the permanent magnet.
The electrophoresis process is divided into anodic electrophoresis and cathodic electrophoresis, and is actually different process methods formed according to electrode polarity setting. Since the anodic electrophoretic paint film contains metal ions, defects of poor corrosion resistance of the coating layer are increasingly exposed. Except aluminum and inert metal, the surface of other metals loses luster due to corrosion, and the requirements of surface decoration of high-grade products cannot be met. Therefore, the surface protection layer of the permanent magnet is usually applied by cathode electrophoresis. The cathodic electrophoresis is to put a cationic electrophoretic paint into an electrophoresis tank provided with an anode electrode (conductive work is cathode), under the action of direct current of electrode voltage, charged paint ions move from the anode to the cathode, and under the action of alkaline electrochemistry generated on the surface of the cathode, insoluble matters are formed and deposited on the surface of the work (cathode), thereby forming coating coverage.
In the production process, in order to improve the production efficiency of the permanent magnet protective layer, a plurality of permanent magnet workpieces are generally put into an electrophoresis tank at one time, all the permanent magnet workpieces are taken out together after the coating is covered, a time interval exists in the process that the permanent magnet workpieces leave the electrophoresis tank and then new permanent magnet workpieces enter the electrophoresis tank, the production efficiency is influenced, the problem that the overall coating quality is uneven when the permanent magnet workpieces are subjected to electrophoresis together is also solved, the quality of the workpiece protective layer is different according to the position difference of the workpieces and the supplement speed difference of electrophoretic coatings near the workpieces, and the overall quality of the workpieces is influenced.
