step four: in the moving process of the gate panel spraying device, the gate panel spraying device is positioned through a positioning guide system (5) on the bottom plate, and the moving track is recorded so as to automatically control gates of the same type;
step five: after the sand blasting operation is finished, closing the sand blasting system (2), returning the gate panel spraying device to the initial position, and closing the driving device (102);
step six: detaching the sand blasting head (202) from the spray head bracket (105), installing the coating spray head (403) on the spray head bracket (105), and starting the spraying system (4); parameters of matching of spraying air pressure, distance between a spray head and a working surface and moving speed of a gate panel spraying device are adjusted through tests to ensure that the spraying effect meets the requirement of the thickness of a coating;
step seven: starting a driving device (102), driving a Mecanum wheel hub (1012) to rotate by a driving motor (1021) through a speed reducer (1022), so that the whole gate panel spraying device moves, and meanwhile, controlling an automatic paint spray head (403) to be opened to start spraying operation;
step eight: after the spraying operation is finished, the spraying system (4) is closed, the gate panel spraying device returns to the initial position, and the driving device (102) is closed.
