[0033] Step 1. The equipment is stably installed through the base 9. After the equipment is powered on, the liquid inlet end of the material pump 21 is connected to the feeding (spraying material) through a pipeline. Step 2. Then place the spoiler on the left end of the conveyor belt main body 11 in the main body assembly 1, and place the mounting claws with through holes facing up and opposite to the clamping assembly 5. Step 3. Then drive the spoiler to move to the right through the conveyor belt main body 11. When the spoiler passes through the guiding box 14 on the left side of the spraying box 13, use the hot air generated by the fan 15 and the heating box 16 to blow off the surface dust, and then move into the spraying box 13 on the support arm 12. Step 4. The material pump 21 drives the nozzle 23 to feed the material, and the first driving rail drives the gear rod 25 to move up and down. The gear rod 25 moves and meshes with the swing gear 22 to drive the nozzle 23 to turn up and down under the swing port 81, and the spraying angle is adjusted to change the spraying position, so that the side with the mounting claw is sprayed; after spraying, the spoiler is moved to the right again to the guide box 14 on the right side of the spray box 13 with the help of the conveyor belt body 11, and the fan 15 and the heating box 16 generate hot air to blow the mounting claw part to accelerate drying, and then the spoiler is moved to the left and re-entered into the spray box 13; Step 5. Since the spray box 13 has no front side wall, the clamping structure can be inserted into the spray box 13 with the help of the transport structure 3 to clamp and fix the spoiler; that is, the first hydraulic cylinder 30 is driven to drive the flip seat 31 to move up and down to adjust the height of the clamping assembly 5; then the second electric slide rail 37 on the flip arm 34 is driven to drive the telescopic arm 38 to move, and the clamping assembly 5 is inserted into the spray box 13, and the first camera 44 in the flip assembly 4 is used to image and determine the installation claw position of the spoiler; Step 6. Insert the first clamping arm 54 in the clamping assembly 5 between the two mounting claws of the spoiler, then drive the third hydraulic cylinder 56 to extend, move the push plate 55 between the bottom plate 51 and the cover plate 53, and drive the moving arm 57 to move relatively in the moving groove 83 of the blocking arm 52 by means of the V-shaped toggle groove 84, thereby driving the second clamping arm 58 to move relatively, so that the second clamping arm 58 is clamped and fixed on the outside of the mounting claw; Step 7. After the spoiler is clamped, the first motor 42 in the flip assembly 4 can be driven to drive the casing 43 to flip a certain angle on the mounting frame 41, or the spoiler can be flipped 180 degrees and positioned above the flip arm 34 to achieve flipping, and then the second electric slide rail 37 can be used to drive the telescopic arm 38 to move and insert the flipped spoiler into the spray box 13, and the telescopic arm 38 can pass through the extension opening of the rear side wall of the spray box 13, so that the spoiler is fully opposite to the spray head 23 for face-changing spraying; Step 8. After the spoiler is sprayed on both sides, the spoiler is flipped to a vertical position and positioned above the flip arm 34; then the second hydraulic cylinder 36 is driven to contract, driving the connecting shaft 33 to flip with the help of the first arm 32, and at the same time, the connecting shaft 33 is movably connected to the second arm 35, and when the connecting shaft 33 flips, the flip arm 34 is driven to flip on the flip seat 31 with the help of the second arm 35, and the flip arm 34 is horizontally positioned above the flip seat 31, and the spoiler is vertically positioned at the front side of the front end of the flip seat 31; Step 9. At this time, imaging can be performed through the second camera 69 on the hanger 62 in the hoisting structure 6 to determine whether there is a spoiler on the boom 713 in the hoisting assembly 71 corresponding to the spoiler. With the aid of the second motor 66 on the upper wall of the hanger 62 supported by the column 61, one of the rotating shafts 63 is driven to rotate through the transmission of the transmission wheel 67 and the transmission belt 68. One of the conveyor wheels 64 is driven to rotate by the rotating shaft 63, so that the conveyor belt 65 rotates on the conveyor wheel 64 and drives a number of hoisting assemblies 71 to rotate circumferentially for transposition; Step 10. As the hoisting assembly 71 rotates and moves, after the spoiler is flipped by means of the flipping assembly 4 and the flipping arm 34, the mounting claws of the spoiler are made to correspond to the boom 713. Then, as the boom 713 moves with the conveyor belt 65, the boom 713 can be inserted into the through holes of the mounting claws, and then the clamping assembly 5 is unlocked to complete the handling and hoisting. By driving the rotation and movement of the spoiler with the boom 713, both walls of the spoiler can face the fan 70, and the air supply of the fan 70 can be used to accelerate drying; Step 11. Since the sizes of spoilers of different specifications, as well as the sizes and spacings of the mounting claws on the spoilers, are different, the clamping position can be adjusted by moving the first clamping arm 54 at the adjustment groove 82, and the spacing of the suspension seats 711 on the conveyor belt 65 can be adjusted by means of the tightening bolts 712. Moreover, the sizes of the spraying box 13 and the guiding box 14 should be larger than the spoiler (the sizes are set according to actual requirements and can be achieved with the mechanical structure of this solution).
