The tablets enter and pass through the multiple sorting channels of the upper tablet sorting component. Then, the front visual inspection component can perform frontal inspection on the tablets conveyed by the upper conveying component. After that, the tablets pass through the first rejection component, which can reject tablets that are judged to have defects on the front. The tablets that are qualified on the front continue to be conveyed under the action of the upper conveying component. Then, the tablets are flipped by the flipping mechanism and enter the lower conveying component with the back side facing up.
