1. A coating apparatus for a substrate with a curved surface, comprising:
a platform having a flat surface;
a coating assembly adjacent to the platform, wherein the coating assembly comprises:
a push frame disposed on the platform; and
a coating wire rod disposed on the push frame, wherein the push frame is configured to push the coating wire rod to scrape a glue on the flat surface so as to form a glue layer on the flat surface;
a carrying stage adjacent to a first side of the flat surface and configured to hold the substrate with the curved surface; and
a transfer printing assembly comprising:
a carrier horizontally movable above the platform and the carrying stage; and
an elastic transfer printing head disposed on a bottom of the carrier and vertically movable, and configured to attach the glue layer on the flat surface and press against the curved surface of the substrate to transfer the attached glue layer to the curved surface.
