Abstract
The invention discloses a two-sided coating method and system. The system comprises two independent coating devices. Each device comprises a trough, a feeding pump, a micro gravure roller and a closed scraper. The two micro gravure rollers are mounted in a vertically staggered mode. The two micro gravure rollers are mutually matched to play the roles of supporting a thin film and tensioning the coated position of the thin film, and therefore the purpose of accurately controlling the coating thicknesses is achieved. Through the system, both double-sided coating and single-sided coating can be achieved. When single-sided coating is needed, one coating device works, and the other coating device is shut down. When double-sided coating is needed, the two coating devices work at the same time. When coating of different kinds of slurry is needed, the different kinds of slurry are placed in the two troughs or tanks. According to the two-sided coating method and system, the thicknesses of coatings on two sides can be controlled accurately, both single-sided coating and double-sided coating can be achieved, and the two sides can be coated with different materials during double-sided coating.
