Coating device

The utility model relates to the technical field of heat dissipation, in particular to a coating device. A coating device is used for coating a heat dissipation material on a domain controller and comprises a displacement mechanism and a coating mechanism, and the displacement mechanism is connected with the coating mechanism and can drive the coating mechanism to move in a first direction; wherein the coating mechanism comprises a container, a nozzle assembly, a rotating assembly and a visual assembly, the container is used for containing a heat dissipation material, the nozzle assembly communicates with the container, a part of the rotating assembly is arranged in the container, the rotating assembly can rotate relative to the container so that the heat dissipation material can flow out through the nozzle assembly, and the rotating speed of the rotating assembly is in positive correlation with the flow speed of the heat dissipation material; the visual assembly is used for collecting domain controller data
