Abstract
A coating apparatus for a substrate with a curved surface includes a platform, a coating assembly, a carrying stage, and a transfer printing assembly. The coating assembly includes a push frame mounted on the platform and a coating wire rod disposed on the push frame. The push frame can push the coating wire rod to scrape a glue on a flat surface of the platform to form a glue layer on the flat surface. The carrying stage can hold the substrate. The transfer printing assembly includes a carrier and an elastic transfer printing head. The carrier is horizontally movable above the platform and the carrying stage. The elastic transfer printing head is disposed on a bottom of the carrier and is vertically movable, and can attach the glue layer on the flat surface and press against the curved surface to transfer the attached glue layer to the curved surface.
