[0041] S1. First, the injection-molded car trunk cover is polished, surface cleaned, and dried;

[0042] S2, placing the cleaned trunk cover of the car on the clamping device, and starting the spraying operation on the trunk cover of the car after the clamping is completed;

[0043] S3. After spraying is completed, the trunk cover of the car is removed from the clamping device and then placed in the baking equipment for drying;

[0044] S4. Finally, the dried trunk lid of the car is subjected to surface inspection;

[0045] The clamping device includes a bottom plate 1, a base 2 is fixedly connected to the top middle position of the bottom plate 1, a turntable 3 is rotatably connected to the top middle position of the base 2 through a rotating shaft, and the turntable 3 is arranged to facilitate the rotation of the clamped trunk cover of the car. In this process, the staff does not need to disassemble and flip the clamped trunk cover of the car, thereby reducing the labor of the staff. A positioning frame 4 is fixedly connected to the top middle position of the turntable 3, a placement pad 5 is fixedly connected to the inner bottom of the positioning frame 4, a threaded rod 6 is threadedly connected to the top of the positioning frame 4, and a knob 7 is fixedly connected to the top of the threaded rod 6. The knob 7 is mainly used to control the rotation of the threaded rod 6, and then control the pressure plate 8 to move up and down. When the knob 7 is rotated forward, the pressure plate 8 moves down and cooperates with the placement pad 5 to clamp the trunk cover of the car. When the knob 7 is rotated reversely, the pressure plate 8 moves up and loosens the trunk cover of the car. The bottom end of the threaded rod 6 is rotatably connected to the pressure plate 8, and the pressure plate 8 is located inside the positioning frame 4.

[0046] A vertical plate 11 is fixedly connected to the top of the bottom plate 1, and the vertical plate 11 is located at the rear of the base 2. An electric cylinder 12 is fixedly connected to the rear side wall of the vertical plate 11. The electric cylinder 12 is mainly used to control the movement of the baffle plate 13. The movable end of the electric cylinder 12 is fixedly connected to the baffle plate 13. A collecting chamber 14 is arranged inside the baffle plate 13. The arrangement of the collecting chamber 14, the suction pipe 15, and the dust suction head 16 is mainly used to absorb the paint floating in the air during the spraying process to prevent the paint floating in the air from causing environmental pollution and affecting the health of the workers. At the same time, the positioning block 17 is inserted into the positioning hole 10, and the positioning frame 4 can also be positioned to prevent it from rotating automatically during the spraying process. The left and right inner walls of the collecting chamber 14 are fixedly connected to the dust suction head 16, and the left and right side walls of the baffle plate 13 are fixedly connected to the suction pipe 15, and the suction pipe 15 is connected to the dust suction head 16, and the end of the suction pipe 15 away from the dust suction head 16 is connected to the vacuum cleaner;

[0047] A positioning block 17 is fixedly connected to the front side wall of the shielding plate 13, and a positioning hole 10 is provided inside the side wall of the positioning frame 4;

By providing the indicator block 18, the positioning column 19 and the groove 20, it is convenient to judge whether the positioning frame 4 is parallel to the baffle plate 13, and it is convenient to accurately insert the positioning block 17 into the interior of the positioning hole 10.

[0049] Two telescopic rods 9 are arranged between the pressing plate 8 and the top of the positioning frame 4, and the two telescopic rods 9 are symmetrically arranged on the left and right sides of the electric cylinder 12. The setting of the telescopic rods 9 is mainly to limit the pressing plate 8 to prevent the pressing plate 8 from rotating with the threaded rod 6. The placement pad 5 is located below the pressing plate 8. A protective pad is arranged at the bottom of the pressing plate 8, and the protective pad and the placement pad 5 are both rubber, which mainly protects the trunk cover of the car. There are multiple positioning holes 10 and positioning blocks 17, and the positioning holes 10 are arranged correspondingly to the positioning blocks 17. There are multiple suction pipes 15 and dust suction heads 16. A filter is arranged inside the dust suction head 16 to facilitate filtering out the paint. The filter can be disassembled and replaced. There are two indicator blocks 18, which are symmetrically arranged on the front and rear sides of the positioning frame 4. The side shape of the positioning column 19 is an inverted "L" shape. The groove 20 and the indicator block 18 are arranged at the same height, and the groove 20 is adapted to the indicator block 18. The electric cylinder 12 is controlled by an external controller.

[0050] The working steps of the clamping device are:

[0051] S21, firstly place the trunk cover of the car on the placement pad 5, then move the pressing plate 8 downward by rotating the knob 7, and clamp and fix the trunk cover of the car with the placement pad 5;

[0052] S22, then spraying the front side of the trunk lid of the car, and starting a vacuum cleaner during the spraying process to absorb the paint floating in the air;

[0053] S23, when the front of the trunk cover of the car is sprayed, the controller controls the electric cylinder 12 to work, so that the shielding plate 13 is separated from the positioning frame 4, and then the turntable 3 is rotated to flip the trunk cover of the car. When the indicator block 18 enters the inside of the groove 20, the rotation of the turntable 3 is stopped, and the controller controls the electric cylinder 12 to work again, so that the shielding plate 13 is attached to the positioning frame 4, and the positioning block 17 is inserted into the inside of the positioning hole 10;

[0054] S24, after the trunk cover of the car is turned over, the back of the trunk cover of the car can be sprayed. After the spraying is completed, the knob 7 is rotated in the opposite direction to move the pressing plate 8 upward, and the trunk cover of the car that has been sprayed can be taken down.
