A robotic arm is installed on a station on one side of the material conveyor, and a paint spray nozzle is connected to the end of the robotic arm. The paint spray nozzle is connected to a paint pipeline, so that the paint spray nozzle can paint the transported workpiece. After the current workpiece is painted, the robotic arm drives the paint spray nozzle to move to the initial position and wait for a period of time. During this period, the material conveyor transports the next workpiece to the painting area, and then the robotic arm drives the paint spray nozzle to paint the workpiece in the painting area.

A portion of the water flows into the second cavity 223 from the second pipeline 221 , causing the second cavity 223 to expand and deform and contact the outer wall of the paint spray head 200 , thereby blocking the outer wall of the paint spray head 200 and the top side of the cover shell 222 .

[0062] refer to Figure 7 and Figure 8The second pipeline 221 is fixedly connected with a second cleaning brush 224, which contacts the outer wall of the paint spray nozzle 200 and is spiral-shaped.
