[0045] The detailed connection means is a known technology in the art, and the working principle and process are mainly introduced below. The specific work is as follows.

[0046] Step 1. The device is stably arranged through the base 9, the device is powered on, the liquid inlet of the material pump 21 is connected with the material supply (spraying material) through the pipeline;

[0047] Step 2. Then place the spoiler on the left end of the conveying belt main body 11 in the main assembly 1, and the mounting claw with a through hole is upward and opposite to the clamping assembly 5;

[0048] Step 3. Then the spoiler is moved to the right by the conveyor body 11, and when it passes through the guide box 14 on the left side of the spraying box 13, the fan 15 and the hot air generated by the heating box 16 are used to blow off the surface dust, and then it moves to the spraying box 13 on the support arm 12;

[0049] Step 4. The spray head 23 is fed by the material pump 21, and the first driven slide rail is driven to move up and down, and the movement of the gear rod 25 is engaged with the swing gear 22 to drive the spray head 23 to flip up and down below the swing opening 81, adjust the spraying angle, change the spraying position, and make one side with the mounting claw to be sprayed; after spraying, the spoiler is moved to the right again by the conveyor body 11 to the guide box 14 on the right side of the spraying box 13, and the fan 15 and the hot air generated by the heating box 16 are used to blow and accelerate the drying of the mounting claw part, and then the spoiler is moved to the left again to enter the spraying box 13;

[0050] Step 5. Since the spraying box 13 has no front side wall, the clamping structure can be inserted into the spraying box 13 to clamp and fix the spoiler by means of the carrying structure 3; that is, the first hydraulic cylinder 30 is driven to drive the flip seat 31 to adjust the height of the clamping assembly 5; then the second electric slide rail 37 on the flip arm 34 is driven to move the telescopic arm 38, the clamping assembly 5 is inserted into the spraying box 13, and the first camera 44 in the flip assembly 4 is used to image and determine the position of the mounting claw of the spoiler;

[0051] Step 6. The first clamping arm 54 in the clamping assembly 5 is inserted between the two mounting claws of the spoiler, then the third hydraulic cylinder 56 is driven to extend, the push plate 55 is moved between the bottom plate 51 and the cover plate 53, and the moving arm 57 is moved in the moving slot 83 of the blocking arm 52 by means of the V-shaped shifting slot 84, thereby realizing the relative movement of the second clamping arm 58, and the second clamping arm 58 is clamped outside the mounting claw for fixation;

[0052] Step 7. When the spoiler is clamped, the first motor 42 in the flip assembly 4 is driven to drive the sleeve 43 to flip a certain angle on the mounting bracket 41, or the spoiler is flipped 180 degrees to be above the flip arm 34 to realize the flipping, then the telescopic arm 38 is moved by the second electric slide rail 37 to insert the flipped spoiler into the spraying box 13, and the telescopic arm 38 can pass through the extension opening of the rear wall of the spraying box 13, so that the spoiler can be fully sprayed on the opposite side by the spray head 23;

[0053] Step 8. When the spoiler is double-sided sprayed, then the spoiler is turned to the vertical state and above the turnover arm 34; then the second hydraulic cylinder 36 is driven to retract, the connecting shaft 33 is turned through the limiting of the first arm rod 32, and the connecting shaft 33 is movably connected with the second arm rod 35, so that the turnover arm 34 is turned on the turnover seat 31 through the second arm rod 35 when the connecting shaft 33 is turned, the turnover arm 34 is horizontally located above the turnover seat 31, and the spoiler is vertically located at the front side of the front end of the turnover seat 31;

[0054] Step 9. At this time, the second camera 69 on the hanger 62 in the hoisting structure 6 can be imaged to determine whether there is a spoiler on the boom 713 in the hoisting assembly 71 corresponding to the spoiler, and the second motor 66 on the upper wall of the hanger 62 supported by the stand 61 is used to drive one of the rotating shafts 63 to rotate through the transmission wheel 67 and the transmission belt 68, one of the conveying wheels 64 is driven to rotate through the rotating shaft 63, the conveying belt 65 is rotated on the conveying wheel 64, and a plurality of hoisting assemblies 71 are circularly rotated and transposed;

[0055] Step 10. After the turnover of the turnover assembly 4 and the turnover arm 34, the mounting claws of the spoiler are corresponded to the boom 713, and then the boom 713 is inserted into the through hole of the mounting claw through the movement of the boom 713 and the conveying belt 65, and the clamping assembly 5 is unlocked to complete the carrying and hoisting; the rotation of the spoiler is driven by the boom 713, so that the two wall surfaces of the spoiler can be opposite to the fan 70, and the drying speed can be accelerated by the air supply of the fan 70;

[0056] Step 11. Since the size of the spoiler of different specifications and the size and spacing of the mounting claws on the spoiler are different, the clamping position can be adjusted by adjusting the movement of the first clamping arm 54 in the adjusting groove 82, and the spacing of the hanger 711 on the conveying belt 65 is adjusted by the jacking bolt 712, and the size of the spraying box 13 and the guide conveying box 14 is greater than that of the spoiler (the size is set according to the actual demand, and the mechanical structure of the scheme can be realized).

[0057] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
