Coating table and slot coating device

Abstract

The application discloses a coating workbench and a slit coating device; the coating workbench comprises a carrier and a lifting support column; the carrier comprises a horizontal coating area, the horizontal coating area comprises a pre-coating area, a uniform coating area and a finishing area in sequence along a coating direction; the uniform coating area is separated from the pre-coating area and the finishing area respectively; the lifting support column is arranged on one side of the uniform coating area; the lifting support column comprises a bearing surface, the bearing surface is used for bearing a to-be-coated piece, and the lifting support column drives the to-be-coated piece to vertically lift in the uniform coating area. The coating workbench is used for coating, the coating operation starts in the pre-coating area, and the coating operation stops in the finishing area, so that the film layer thickness of the surface of the to-be-coated piece is not affected by the starting and stopping of the liquid, and the uniformity of the coating film layer thickness is obviously improved.
