1. A coating device for coating viscous ink on a substrate to form a film, the substrate conveyed along a plummet direction, the substrate comprising two opposite mounting surfaces and a plurality of holes, the mounting surfaces being opposite and uneven, the holes separately formed on the mounting surfaces, the coating device comprising:
an accommodating mechanism, for accommodating the viscous ink and comprising a channel for providing the substrate to pass through; a coating mechanism, disposed above the accommodating mechanism, and for coating the viscous ink on the substrate passing through the channel, the coating mechanism comprising two coating units, the two coating units separately disposed on two opposite sides of the substrate, wherein the coating units separately transfer the viscous ink in the accommodating mechanism onto the mounting surfaces, each coating unit comprises a rotatable filling roller for filling with pressure the viscous ink in the hole on the corresponding mounting surface to form an initial layer; and a forming mechanism, disposed above the coating mechanism, and for scraping the initial layer covering on the mounting surfaces to adjust the thickness of the initial layer to form the film. |
