This invention discloses a coating device for wind turbine blades, comprising a coating box with two partitions fixed inside. Paint tanks are located at the top and bottom of the coating box, and are fixed to the partitions via multiple connecting blocks. Multiple coating mechanisms are arranged on the side of each paint tank near the partitions, penetrating through the partitions. This invention utilizes the shape of the blade to design a roller coating method. The blade is inserted into the device and then pulled out, completing the blade coating operation. This not only avoids paint waste but also effectively inhibits paint diffusion and protects the health of surrounding workers, as the coating process is completed within the device.
