Problems solved by technology

[0002] The scraper blade of SMT printing machine is used to print solder paste or red glue on the printed circuit board. Since there is sliding friction between the edge of the scraper blade of SMT printing machine and the stencil of SMT printing machine during the printing process, if the edge of the scraper blade of SMT printing machine With sharp corners and burrs, the stencil of the SMT printing machine is easily scratched, worn and deformed by the scraper blade of the SMT printing machine
The SMT printing machine scraper blade is also easily corroded by the chemical components in solder paste and red glue during the printing process, and the SMT printing machine scraper blade is also easily worn by the steel mesh, which greatly reduces the SMT printing machine scraper blade and SMT printing machine screen. service life, increasing the maintenance cost of SMT printing machines, reducing low production efficiency
The quality of printed products cannot be guaranteed

Abstract

The invention discloses an SMT (Surface Mounting Technology) printing machine film scraper and a manufacturing method thereof. The SMT printing machine film scraper comprises a blade body, wherein a coating with ultrahigh hardness, ultralow friction coefficient, wear loss resistance and corrosion resistance is electroplated on the surface of the blade body in a vacuum manner, and a cutting edge of the blade body is processed into an arc chamfer and is passivated. The SMT printing machine film scraper has functions of ultrahigh hardness, ultralow friction coefficient, wear loss resistance and corrosion resistance, thereby reducing cost of maintenance and replacement, increasing production efficiency, improving printing quality and enhancing quality of the manufactured film scraper, also being capable of preventing an SMT printing machine steel mesh from being scratched, damaged, worn and deformed by the film scraper and greatly prolonging the service life of the SMT printing machine film scraper and the SMT printing machine steel mesh. The method has the advantages of simple and reliable machining process, and better composite performances of the blade body and the coating with the functions of ultrahigh hardness, ultralow friction coefficient, wear loss resistance and corrosion resistance.
