After the upper end surface of the product is irradiated with light, the conveying mechanism 20 moves the product to the flipping mechanism 30, and the flipping mechanism 30 flips the product and then returns it to the conveying mechanism 20. The conveying mechanism 20 conveys the flipped product to the irradiation position, and adjusts the position of the UV lamp source assembly 44 through the linear moving assembly 42 and the rotating assembly 43 again. Finally, after completion, the product is sent out, and the product is flipped by the flipping mechanism 30 and returned, so that both the front and back sides of the product can be irradiated with light.
