The control switch 433 is for controlling the opening and closing of the automatic painting device. The lifting of this device is controlled by the foot switch 43 to ensure the accuracy of adjustment and improve the spraying quality. It is convenient for the staff to control through the control switch 433 and improves the work efficiency.

[0028] In a more optimal embodiment, the connecting rod 1 includes a mother rod 104 and a son rod 105. The mother rod 104 and the son rod 105 are coaxially connected. At one end of the mother rod 104 away from the son rod 105, a chute 101 is opened. The cross-section of the chute 101 is rectangular. A slider 102 is correspondingly arranged in the chute 101. An axial positioning screw hole 103 is arranged in the slider 102. At the end of the son rod 105 away from the mother rod 104, a thread is correspondingly arranged for the positioning screw hole 103. The son rod 105 of one connecting rod 1 is threadedly connected to the slider 102 in the mother rod 104 of another connecting rod 1. The length is adjusted by the movement of the slider 102 in the chute 101. The connecting rod 1 and the connecting rod 1 can form a long rod of any length, enabling the device to adapt to workpieces to be sprayed of any size.

[0029] The spray gun support pipe 3 runs through up and down. Below the spray gun support pipe 3, there is a bayonet 9. The nozzle of the automatic spray gun faces downward and is clamped by the bayonet 9. A number of through holes 32 are arranged on the side of the spray gun support pipe 3. The through holes 32 are responsible for connecting the spray gun to the paint pipe. On the other side of the spray gun support pipe 3, there is a limit ring 33. The inner diameter of the limit ring 33 has a clearance fit with the outer diameter of the connecting rod 1. At the top of the limit ring 33, there is a limit screw hole 331. After installing the limit ring 33 at the specified position on the connecting rod 1, the limit ring 33 is fixed by screwing a screw through the limit screw hole 331.

By means of the brake roller 41, it is convenient for the staff to adjust the position of the moving device 4, facilitating the accurate placement of the spray gun support pipe 3 above the position to be sprayed. After the position adjustment is completed, the moving device 4 is limited by the brake plate 411.

[0031] An opening groove 451 is provided on the vertical main body 45. The width of the opening groove 451 is greater than the width of the positioning ring 455. By providing the opening groove 451, the positioning ring 455 is arranged outside the vertical main body 45, facilitating the connecting rod 1 to pass through the positioning ring 455. It enables the staff to directly change the lateral position of the automatic spray gun by moving the connecting rod 1, improving the spraying efficiency.

[0032] The lead screw device 6 includes a driving motor 452 and a lead screw 453. The output end of the driving motor 452 is connected to the lead screw 453. The model of the driving motor 452 is Y90L-6. Through the lead screw device 6, the up and down movement of the positioning ring 455 is realized, thereby achieving the up and down movement of the automatic spray gun to adapt to spraying objects at different heights. At the same time, by controlling the height of the automatic spray gun, the spraying density is controlled to achieve different spraying effects.

[0033] Sliding rails 8 are provided on both sides inside the vertical main body 45. Fixed plates 7 corresponding to the sliding rails 8 are provided on both sides of the positioning ring 455. The positioning ring 455 is fixed by the cooperation of the sliding rails 8 and the fixed plates 7, ensuring good stability of the positioning ring 455 even during the rotation of the vertical main body 45.

[0034] Workflow: First, the spray gun support pipe 3 is threaded onto the connecting rod 1, and then the position of the limiting ring 33 and the connecting rod 1 is fixed by screwing a screw into the limiting screw hole 331.

[0035] Secondly, the connecting rod 1 is assembled. The sub-rod 105 of one connecting rod 1 is threadedly connected to the slider 102 in the mother-rod 104 of another connecting rod 1. The length is adjusted by the movement of the slider 102 in the chute 101 to form a long rod of a specified length.

[0036] After that, the automatic spray gun is installed into the spray gun support pipe 3. The assembled connecting rod 1 is installed on the positioning ring 455 on the moving device 4. Then, the brake plate 411 is lifted, and the position of the moving device 4 is adjusted by the brake roller 41. After the adjustment is completed, the brake plate 411 is stepped on to fix the moving device 4.

[0037] When the automatic spray gun is in the braking position, the up and down position of the automatic spray gun is adjusted through the up switch 431 and the down switch 432 in the foot switch 43. Then, the position of the automatic spray gun can be adjusted by moving the connecting rod 1 or pushing the moving device 4.
