The workshop 1 contains containers that have been produced and welded. A vision camera 18 is installed on the lower surface of the roof of the workshop 1. The vision camera 18 is used to photograph the placement of the containers in the workshop 1. A crane 2 is also installed on the upper part of the two side walls of the workshop 1. The crane 2 is controlled by the crane control system and can move back and forth in the workshop 1. A boom 3 is also installed below the crane 2, and a paint mist structure is installed below the boom 3.

[0028] The paint mist structure includes a lifting column 4, which is located inside the boom 3. The surface of the lifting column 4 is also provided with a third conical wheel 11, which is located inside the boom 3. The lifting column 4 and the third conical wheel 11 are engaged by threads. The surface of the third conical wheel 11 is also provided with a fourth conical wheel 12. The center of the fourth conical wheel 12 is connected to a lifting motor 13, which is fixedly installed on the outer surface of the boom 3.

[0029] Below the lifting column 4, there is a cylinder 5. The inner wall of the cylinder 5 has recesses. A disc 7 is fixedly installed in the recesses of the inner wall of the cylinder 5. The center of the disc 7 is located on the lower surface of the lifting column 4 and can rotate on the lower surface of the lifting column 4. A first conical wheel 8 is distributed on the upper surface of the disc 7. The first conical wheel 8 is annular. A second conical wheel 10 is also provided on the surface of the first conical wheel 8. A rotary motor 9 is connected to the center of the second conical wheel 10.

[0030] The lower end of the cylinder 5 is fixedly connected to a lifting plate 6. The lifting plate 6 has a notch, and an upper fixed column 16 is also fixedly connected to the notch. A rotating column 14, a lower fixed column 17 and a stretching motor 15 are erected on the surface of the lifting plate 6. One end of the rotating column 14 is connected to the drive shaft of the stretching motor 15. The two ends of the center surface of the rotating column 14 are provided with threaded grooves, and the threaded grooves at both ends of the center surface of the rotating column 14 are rotated towards the center of the rotating column 14.

[0031] The upper fixed column 16 has upper sliding columns 20 evenly distributed on its surface, which can move back and forth on the surface of the upper fixed column 16. The lower fixed column 17 has side sliding columns 19 evenly distributed on its surface, which can move back and forth on the surface of the lower fixed column 17. The upper end of the upper sliding column 20 is located in a threaded groove on one side of the rotating column 14. The lower end of the upper sliding column 20 is fixedly connected to a lower nozzle 24. The lower nozzles 24 are connected by a hose.

[0032] An ultrasonic sensor 23 is also fixed to the lower surface of the lifting plate 6. The ultrasonic sensor 23 is used to detect the height of the lifting plate 6 from the ground. When the container to be painted is placed in the workshop 1, the vision camera 18 detects the placement of the container. Then, the overhead crane 2 moves the paint mist structure to one end above the container. The lifting motor 13 starts, driving the fourth conical wheel 12 and the third conical wheel 11 to rotate. The rotation of the third conical wheel 11 drives the lifting column 4 and the lifting plate 6 to descend to a certain height. Then, the extension motor 15 starts to rotate, driving the rotating column 14 to rotate, so that the side sliding column 19 and the upper sliding column 20 are proportionally converged and moved away in the threaded groove on the surface of the rotating column 14, so that the lower nozzle 24 and the side nozzle 25 are appropriately aligned. The width of the container is determined, and then the overhead crane 2 and the lower spray valve 22 are started, moving the lifting plate 6 from one end of the container to the other. Atomized paint is sprayed through the lower nozzle 24 to complete the paint spraying on the upper surface of the container. Then, the lower spray valve 22 is closed, and the side spray valve 21 and the lifting motor 13 are started, moving the lifting plate 6 from the top of the container to the ground. Atomized paint is sprayed through the side nozzle 25 to complete the paint spraying on one side of the container. The rotary motor 9 and the second conical wheel 10 are started to rotate, driving the first conical wheel 8 and the disc 7 to rotate. The lifting plate 6 rotates 90 degrees, and the side spray valve 21 and the lifting motor 13 are started to complete the paint spraying on the other side of the container. This process is repeated until the paint spraying on all four surfaces of the container is completed.

[0035] When the upper surface of the container is being painted and the trolley is started, pin 11 of chip U1 sends a high level, chip U2 is turned on, pin 6 of chip U1 sends a PWM waveform adapted to the speed of the trolley, and pin 7 of chip U1 sends a PWM waveform adapted to the width of the lower nozzle. The greater the speed of the trolley and the wider the lower nozzle, the greater the duty cycle of the high level in the PWM waveforms sent by pins 6 and 7 of chip U1. The greater the amplified voltage formed by transistor Q1 and chip U3, the greater the voltage signal V0, the greater the opening of the lower spray valve, and the greater the paint flow rate sprayed from the lower nozzle.

[0037] When the container is painted, the trolley starts, pin 12 of chip U1 outputs a high level, chip U4 is turned on, pin 8 of chip U1 outputs a PWM waveform adapted to the speed of the trolley, and pin 9 of chip U1 outputs a PWM waveform adapted to the width of the side nozzle. The higher the speed of the trolley and the wider the width of the side nozzle, the larger the duty cycle of the high level in the PWM waveforms output by pins 8 and 9 of chip U1. The larger the amplified voltage formed by transistor Q2 and chip U5, the larger the voltage signal V1, the larger the opening of the lower spray valve, and the larger the paint flow rate sprayed from the lower nozzle.
