[0021] A supporting slide 6 is fixedly mounted on the surface of the first tripod 4 , and a first cylinder 7 is fixedly mounted on the surface of the second tripod 5 . The telescopic end of the first cylinder 7 is in movable contact with the surface of the supporting slide 6 , wherein a roller 14 is rotatably mounted on the telescopic end of the first cylinder 7 , and the roller 14 rolls along the surface of the supporting slide 6 .

[0022] There are two supporting slides 6 and two first cylinders 7. The two supporting slides 6 are respectively set on the front and rear sides of the first tripod 4, and the two first cylinders 7 are respectively set on the front and rear sides of the second tripod 5 to improve the stability of the lifting frame 3 moving up and down.

[0023] The lifting frame 3 includes a mounting frame 8 and a flip frame 9. The second tripod 5 is fixedly mounted on the lower side of the mounting frame 8. The flip frame 9 is rotatably connected to the mounting frame 8. A plurality of transmission rollers 10 are rotatably mounted on the upper surface of the mounting frame 8.

[0024] A second cylinder 11 is fixedly mounted on the end of the turning frame 9 , a positioning block 12 is fixedly mounted on the end of the mounting frame 8 , and the telescopic end of the second cylinder 11 abuts against the positioning block 12 .

[0025] The upper opening of the electrostatic pool 1 is fixedly installed with a loading pallet 15 and a unloading pallet 16, and the base 2 is fixedly installed in the electrostatic pool 1. When the telescopic end of the first cylinder 7 is extended and retracted, the lifting frame 3 is driven to move up and down, and the upper plane of the lifting frame 3 is flush with the upper plane of the loading pallet 15 and the unloading pallet 16. A plurality of conveying rollers 17 are rotatably installed on the upper surfaces of the loading pallet 15 and the unloading pallet 16.

[0026] By setting up a lifting frame 3 consisting of a mounting frame 8 and a turning frame 9, and arranging a transmission roller 10 on the turning frame 9, the turning frame 9 can be driven to turn to a certain inclination angle by utilizing the extension and contraction of the second cylinder 11.

The first cylinder 7 moves in a telescopic manner. At this time, the connecting rod 13 moves in accordance with the Figure 3 The middle arc arrow swings, and the turning frame 9 follows Figure 3 The height of the turning frame 9 can be adjusted by translating the middle straight arrow. When the turning frame 9 falls into the electrophoretic pool 1, the height of the turning frame 9 is controlled by the extension and contraction of the first cylinder 7, so that the parts are completely or partially immersed in the electrophoretic liquid for electrophoretic spraying. When the first cylinder 7 is extended, the turning frame 9 is lifted to a position flush with the upper plane of the loading tray 15 and the unloading tray 16. The second cylinder 11 is extended to push the turning frame 9 to flip to a certain inclination angle, and the parts slide onto the unloading tray 16 to complete the unloading.

The bottom surface of the auxiliary bracket can be a flat plate. The specific shape of the upper side of the auxiliary bracket is determined by the shape of the parts and will not be elaborated here.
