Fully-automatic solder paste printer with adjustable scraping knife

Abstract

The invention provides a fully automatic solder paste printing machine with an adjustable scraper, which increases the angle at which the scraper adapts to the surface of the stencil to realize the practicability of the scraper in the printing process, and adjusts the rotation angle of the scraper so that Under different requirements, the squeegee has different restrictions on its rotatable angle, including the casing, clamping and lifting system, platform correction system, guide rail transportation system, stencil frame clamping system, squeegee printing system and subsequent cleaning system. Among them, all The scraper printing system includes a fixed frame, a through-shaft and a scraper, the scraper is fixed at the lower end of the fixed frame, the through-shaft includes a sheathing part, and a tightening part installed on the sheathing part, and the fixed The frame is socketed on the threading part through the through hole, and there is a turning part above the fixed frame, and the turning part includes a turning surface and is used to connect the threading part and the turning surface. the connection part.

Description

technical field [0001] The invention relates to the technical field of circuit board manufacturing, in particular to a fully automatic solder paste printing machine with an adjustable scraper. Background technique [0002] The application of electronic products has penetrated into all aspects of life, and people's manufacturing requirements for electronic products are getting higher and higher, because electronic products are becoming smaller and more sophisticated, and the production of printed circuit boards (PCBs) of electronic products must be produced by surface mount technology (SMT) ) equipment, the solder paste printing of the first process of production is done by the solder paste printing machine, so the processing of the first process largely determines the production quality of printed circuit boards (PCB). At present, the solder paste printing of printed circuit boards (PCB) is mostly completed by semi-automatic solder paste printing machines or fully automatic ...

AI Technical Summary

Problems solved by technology

At present, the solder paste printing of printed circuit boards (PCB) is mostly completed by semi-automatic solder paste printing machines or fully automatic solder paste printing machines, and is composed of multiple production systems. Each system cooperates with each other and completes its own tasks to ensure Integrity of circuit board printing, one of the most important links is the solder paste printing link. For example, the Chinese patent document with the application number CN201420229924.4 has announced the suspension scraper system of the automatic solder paste printing machine. In this technical solution In, "the front knife support shaft is equipped with a front knife limit block located above the front knife connecting plate" to realize "the suspended blade can automatically adapt to the surface of the steel mesh to ensure that the solder paste can be evenly printed on the PCB ", however, the height distance between the front knife connecting plate and the front knife limit block is too small, and because the distance is a fixed distance, the angle adaptability of the blade is not sufficient, and it cannot meet the deflection of a large angle
