Problems solved by technology

In the industry, screen printing equipment is usually used to print the metal paste on one end face of the ceramic vacuum tube through a screen. After drying the metal paste on the end face, replace the screen, and use a slightly thinner metal paste than the previous pass to repeat on the ceramic vacuum tube. Print again on the end surface of the ceramic vacuum tube. The purpose of the repeated printing is to correct and fill

Abstract

The invention discloses screen printing equipment for coating the end face of a ceramic vacuum tube. The screen printing equipment comprises a lifting mechanism, a printing mechanism used for printingmetal paste on the end face of the ceramic vacuum tube, a paste collecting mechanism used for recycling the metal paste remaining on a silk screen during printing operation, and feeding and discharging mechanisms used for inputting and outputting a plurality of ceramic vacuum tubes during operation. According to the screen printing equipment, automatic feeding and discharging of a plurality of products can be achieved through the feeding and discharging mechanisms, and the simultaneous coating operation of the multiple ceramic vacuum tubes is achieved; compared with traditional equipment thatcan be used for printing one ceramic vacuum tube only every time, the screen printing equipment has the advantages that the printing efficiency is improved greatly; the metal paste remaining on the silk screen is recycled into a paste collecting tank through a paste collecting scraper of the paste collecting mechanism, and the recycling of materials is achieved; and the waste of the materials canbe reduced effectively.

Description

technical field [0001] The invention relates to a screen printing device for coating the end surface of a ceramic vacuum tube. Background technique [0002] At present, metal paste coating is one of the key technologies for the metallization of ceramic vacuum tubes, and the coated paste is required to have good flatness, strong consistency, and high density after high-temperature firing. In the industry, screen printing equipment is usually used to print the metal paste on one end face of the ceramic vacuum tube through a screen. After drying the metal paste on the end face, replace the screen, and use a slightly thinner metal paste than the previous pass to repeat on the ceramic vacuum tube. Print again on the end surface of the ceramic vacuum tube. The purpose of the repeated printing is to correct and fill the defects of the paste surface in the first printing with the second pass of thinner metal paste. After drying again, use the same method to print the ceramic vacuum ...
