US 2020/0047209 A1 · Coating method and a coating device

Abstract

The present disclosure relates to a coating method and a coating device, configured to place a surface material on the surface of an object. The coating method includes: obtaining a three-dimensional image of the object by a scanning element providing a structured light, sequentially moving the nozzle according to the pixels of the three-dimensional image, and spraying the surface material on the surface of the object. The coating device includes a structured light scanning element, providing a scanning light beam to the object and capturing a three-dimensional image; a processing unit; and a nozzle. The processing unit is electrically connected to the structured light scanning element and the nozzle. The processing unit receives the three-dimensional image, moves the nozzle according to the pixels of the three-dimensional image, and sprays the surface material onto the surface of the object.
