[0056] In actual operation, products are conveyed by a conveyor belt mechanism. During the conveying process, anti-stacking components and guide components transport the products one by one to the feeding motor component. The feeding motor component then transfers the products one by one to the turntable. After the trigger sensor component at the turntable senses the product, it transmits the signal to the back-end terminal (PC). Then, as the turntable rotates, the products are inspected by the first, second, third, and fourth station camera components. After the inspection is completed, the products are sorted into the designated unloading boxes by the unloading box component.
