[0034] See Figure 1 , further comprising a first protective box 35 and a second protective box 36. A first protective box 35 is connected to the left side of the rotating frame 6, and a first motor 11 is located inside the first protective box 35. Second protective boxes 36 are connected to the rear sides of the guiding frames 7, and a second motor 13 is located inside the second protective boxes 36.

[0035] Initially, the telescopic rod of the cylinder 17 is in the extended state. The staff installs the electric slide rail 1 on the solid object, then places the car body shell on the tops of the four placing blocks 9, and then controls the telescopic rod of the cylinder 17 to shorten, driving the moving frame 18 to move downward. The moving frame 18 drives the first slide plate 19 to move downward, the first slide plate 19 drives the circular block 16 to move downward, and the circular block 16 drives the moving column 14 and the clamping block 15 to move downward. The moving column 14 rotates on the placing block 9, so that the clamping block 15 moves downward and rotates at the same time, enabling the clamping block 15 to clamp the car body shell. Subsequently, the staff controls the electric slide rail 1 to drive the moving platform 2 to move to the right. The moving platform 2 drives the rotating shaft 5 to move to the right, the rotating shaft 5 drives the rotating frame 6 to move to the right, and the rotating frame 6 drives the car body shell to move to the right for conveying the car body shell above the electrophoresis tank. Then, the output shaft of the stepping motor 4 is controlled to rotate 180 degrees, driving the rotating shaft 5 to rotate 180 degrees, and the rotating shaft 5 drives the rotating frame 6 to rotate 180 degrees, thereby driving the car body shell to rotate 180 degrees and rotating the car body shell into the electrophoresis tank, immersing the car body shell in the electrophoresis buffer solution for pre-treatment electrophoresis. At this time, the electric slide rail 1 is still operating and still conveying the car body shell. After the car body shell is processed, the output shaft of the stepping motor 4 is controlled to continue rotating 180 degrees, driving the car body shell to rotate 180 degrees and moving the car body shell out of the electrophoresis tank. Then, the telescopic rod of the cylinder 17 is controlled to extend, driving the first slide plate 19 to move upward, the first slide plate 19 drives the circular block 16 to move upward, and the circular block 16 drives the moving column 14 and the clamping block 15 to move upward to release the car body shell. At the same time, the moving column 14 rotates reversely on the placing block 9, so that the clamping block 15 can rotate reversely and turn away the clamping block 15, facilitating the staff to remove the car body shell from the placing block 9. If the sizes of the car body shells are different, the positions of the placing blocks 9 can be adjusted. The output shaft of the first motor 11 drives the first bidirectional lead screw 10 to rotate, and the first bidirectional lead screw 10 drives the two guide frames 7 to move towards or away from each other, so that the placing blocks 9 on the left and right sides can move towards or away from each other. The output shaft of the second motor 13 drives the second bidirectional lead screw 12 to rotate, and the second bidirectional lead screw 12 drives the two sliders 8 in the same guide frame 7 to move towards or away from each other, so that the two placing blocks 9 in the same guide frame 7 can move towards or away from each other, adjusting the positions of the placing blocks 9 so that car body shells of different sizes can also be placed on the tops of the four placing blocks 9, enabling the clamping block 15 to clamp car body shells of different sizes, with greater adaptability and versatility. The first bellows 30 and the second bellows 31 can protect the first bidirectional lead screw 10 to prevent the electrophoresis buffer solution from falling on the first bidirectional lead screw 10. When the guide frame 7 moves, the first bellows 30 and the second bellows 31 will adaptively extend and contract to prevent the first bellows 30 and the second bellows 31 from affecting the movement of the guide frame 7. The third bellows 32 and the fourth bellows 33 can protect the second bidirectional lead screw 12.Prevent the electrophoresis buffer from falling onto the second double lead screw 12. When the slider 8 moves, the third bellows 32 and the fourth bellows 33 will adaptively extend and contract to prevent the third bellows 32 and the fourth bellows 33 from affecting the movement of the slider 8. The first protection box 35 can protect the first motor 11 to prevent the electrophoresis buffer from falling onto the first motor 11. The second protection box 36 can protect the second motor 13 to prevent the electrophoresis buffer from falling onto the second motor 13.

[0036] Embodiment 2: On the basis of Embodiment 1, refer to Figure 6 and Figure 7 , it further includes a collection mechanism. The collection mechanism includes a moving plate 20, an electric guide rail 21, a second sliding plate 22, a collection box 23, a discharge pipe 24 and a valve 25. The lower part of the front side of the moving table 2 is connected with the moving plate 20 by bolts. The moving plate 20 is rotationally connected with the rotating shaft 5. Electric guide rails 21 are connected to both the left and right sides of the moving plate 20 by bolts. The tops of the sliding blocks of the electric guide rails 21 are both connected with the second sliding plates 22. The bottoms of the two second sliding plates 22 are jointly connected with the collection box 23. The rear side of the bottom of the collection box 23 is communicated with the discharge pipe 24, and a valve 25 is installed on the discharge pipe 24.

[0037] Refer to Figure 8 , it further includes an opening and closing mechanism. The opening and closing mechanism includes a gear 26 and a rack 27. The handwheel of the valve 25 is connected with the gear 26. The middle of the lower part of the front side of the moving plate 20 is connected with the rack 27, and the rack 27 meshes with the gear 26.

[0038] Refer to Figure 7 , it further includes a support plate 34. The left and right sides of the lower part of the front side of the moving plate 20 are both connected with the support plate 34, and the top of the support plate 34 contacts the bottom of the collection box 23.

[0039] Initially, the valve 25 is in the open state. After the car body is removed from the electrophoresis tank, the electric guide rail 21 is controlled to drive the second slide plate 22 to move forward. The second slide plate 22 drives the collection frame 23 to move forward, and the collection frame 23 is moved below the car body, so that the residual electrophoresis buffer solution on the car body falls into the collection frame 23. There is no need to stop and wait for all the residual electrophoresis buffer solution on the car body to drain completely, enabling the electric slide rail 1 to keep running and continuously convey the car body, thereby improving the work efficiency. The rotary rack 6 and the car body will move away from above the electrophoresis tank to perform the next process. The support plate 34 can support the collection frame 23 to improve the stability of the collection frame 23. At the same time, when the collection frame 23 moves forward, it will drive the discharge pipe 24 and the valve 25 to move forward. The valve 25 drives the gear 26 to move forward. The gear 26 rolls on the rack 27, causing the gear 26 to rotate. The gear 26 drives the valve 25 to rotate and close the valve 25 to prevent the electrophoresis buffer solution in the collection frame 23 from leaking. When the rotary rack 6 moves back above the electrophoresis tank, the electric guide rail 21 is controlled to drive the second slide plate 22 to move backward. The second slide plate 22 drives the collection frame 23 to move backward. The collection frame 23 drives the discharge pipe 24 and the valve 25 to move backward. The valve 25 drives the gear 26 to move backward. The gear 26 rolls on the rack 27, causing the gear 26 to rotate in the reverse direction. The gear 26 drives the valve 25 to rotate in the reverse direction and open the valve 25. The electrophoresis buffer solution in the collection frame 23 is discharged into the electrophoresis tank through the discharge pipe 24.
