Multi-pin glass packaging photoelectron pipe shell surface processing method

Abstract

The invention discloses a multi-pin glass packaging photoelectron pipe shell surface processing method. Firstly, an alkaline solution is used for softening a metal oxidation layer on the surface of ato-be-treated workpiece, an acid solution is used for neutralizing the alkaline solution on the surface of the to-be-treated workpiece after softening is carried out, a sand blasting technology is used for removing the softened metal oxidation layer on the surface of the to-be-treated workpiece, the surface of the to-be-treated workpiece can be effectively prevented from being scratched, an oxidation layer on the surface of a stainless steel shell is effectively and evenly removed through ultrasonic wave and electrochemical polishing treatment, and meanwhile, gloss on the glass surface can still be kept after it is guaranteed that sand blasting is completed; and by means of the technology, multi-pin glass packaging photoelectron pipe shell surface processing can be carried out, oxide skinon the pipe shell surface can be effectively treated, the pipe shell surface can generate the mirror surface effect, the glass surface and the overall device size cannot be damaged, harms to the environment and the human body are small, and the multi-pin glass packaging photoelectron pipe shell surface processing method is suitable for large-scale and industrial production.

Description

technical field [0001] The invention belongs to the surface treatment process of a glass-sealed optoelectronic tube shell, in particular to a surface treatment method for a multi-needle glass-sealed optoelectronic tube shell. Background technique [0002] Optoelectronic shells play a pivotal role in the development of optoelectronic technology. With the development of optoelectronic application technology in the new century, the usage of optoelectronic shells is increasing day by day. Optoelectronic tube shells are products with high technology and long service life, and there are strict requirements on their quality and appearance during the preparation process. The production process of optoelectronic tube shells is relatively complicated, and the materials are often made of stainless steel, corrosion-resistant alloys, high-temperature alloys, etc., and are packaged by glass sealing. During the mechanical processing of the base material, a large number of scratches and po...

AI Technical Summary

Problems solved by technology

During the mechanical processing of the base material, a large number of scratches and polishing marks will be generated on the surface of the base material. At the same time, a large number of oxides will be generated on the surface of the base material during the high-temperature sealing process. These defects will affect the use of the shell. life, reducing the corrosion resistance of the shell, while the appearance of the shell is not beautiful

[0003] For the above-mentioned defects, although the existing treatment process can remove the surface defects and scale of the stainless steel substrate to a certain extent, a large amount of highly volatile HF will be used in the treatment process, which will cause damage to the operator and the environment. At the same time, the glass surface and the wire end will be damaged during the processing.

Patent CN 103132128 B discloses a stainless steel electrochemical polishing solution and its use method. The method uses electrochemical polishing to treat the surface of the stainless steel shell, and removes the burrs on the shell surface through the tip discharge effect, but the method takes a long time to process the workpiece , the processing is not uniform, which will have a negative impact on the key dimensions of the entire shell during the processing, making the wire end round and increasing the size error
