[0040] Specific implementation and principle:

[0041] In practical application of the present invention, the exterior decoration part whose surface is to be flame treated is placed on the contour block 51 on the panel 43, and the exterior decoration part is fixed by adsorption through a plurality of vacuum suction cups 52;

[0042] Then, the output shaft of the right-angle motor 2 at the bottom of the fixed base 1 is controlled to drive the rotating base 3, the connecting frame 4 and the exterior decoration parts thereon to rotate to the industrial robot. The flame gun on the end effector of the industrial robot is used to flame treat the surface of the exterior decoration panel. After the flame treatment of the exterior decoration panel surface is completed, the output shaft of the right-angle motor 2 at the bottom of the fixed base 1 is controlled to drive the rotating base 3, the connecting frame 4 and the exterior decoration parts thereon to rotate to the cooling mechanism 7.

[0043] Next, the air pump 1 75 of the air supply assembly 1 71 first pumps the cold air through the air outlet duct 1 73, the main pipe 1 74, and the air supply duct 1 741 into the bellows 711, and then blows toward the surface of the exterior panel through the air outlet scoop 712. When the cold air is in the air outlet scoop 712, some of the cold air will blow toward the baffle 715 of the air outlet scoop 712, causing the air outlet scoop 712 to swing. The air outlet scoop 712 is then reset by the torsion spring 716 on the rotating shaft 713. When the air supply assembly 1 71 completes cooling the exterior trim, the output shaft of the right-angle motor 2 at the bottom of the control fixing base 1 drives the exterior trim to rotate to the air supply assembly 2 72.

[0044] Next, the cold air is pumped by the second air pump 78 of the second air supply assembly 72 through the second air outlet pipe 76, the second main pipe 77, and the second air supply pipe 771 into the bellows 711. The cold air is then blown toward the surface of the exterior panel through the air outlet scoop 712. When the cold air is in the air outlet scoop 712, some of it is blown toward the baffle 715 of the air outlet scoop 712, causing the air outlet scoop 712 to swing. The torsion spring 716 on the rotating shaft 713 then resets the air outlet scoop 712.

[0045] This completes the step-by-step cooling of the exterior trim, preventing the exterior trim from being rapidly cooled, which would result in poor quality of the exterior trim.

[0046] In summary, the present invention first pre-cools the exterior trim through the air supply component 1 71, and then performs secondary cooling on the exterior trim through the air supply component 2 72. When the cold air is in the air outlet scoop 712, part of the cold air will be blown toward the baffle 715 of the air outlet scoop 712, thereby causing the air outlet scoop 712 to swing, and the air outlet scoop 712 is reset through the torsion spring 716 on the rotating shaft 713, so that the hot air is diffused from both sides, thereby completing the step-by-step cooling of the exterior trim, avoiding rapid cooling of the exterior trim, and greatly improving the quality of the exterior trim.

[0047] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the present invention, or the present utility invention and technical solution are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
