The refrigerator door panel can be automatically and fully sprayed with paint, and the painting effect is good and the efficiency is high.

[0010] The utility model is further configured as follows: it also includes a third drive motor, and the third drive motor is used to drive the stud to rotate.

[0011] By adopting the above technical solution, the driving motor three drives the stud to rotate, and only one person is required to place the refrigerator door panel between the clamping plates to clamp and fix the refrigerator door panel, which saves manpower and is simple to use.

[0012] The utility model is further configured as follows: a buffer pad is provided on the inner side of the splint.

[0013] By adopting the above technical solution, it is prevented that the clamping plate is in direct contact with the refrigerator door panel, causing wear on the side of the refrigerator door panel and reducing the quality of the refrigerator door panel painting process.
