then, the turnover mechanism 6 drives the product receiving platform 4 to turn over to a photographing position, the opening of the cup-shaped product 9 faces the first visual detection device 5, the first visual detection device 5 is driven by the reciprocating device 7 to respectively aim at each cup-shaped product 9 and carry out visual detection on the interior and the cup mouth of the cup-shaped product;

then, the product receiving platform 4 is driven by the turnover mechanism 6 to turn over to a second horizontal position, the openings of the cup-shaped products 9 face downwards, and the conveying line 8 receives the cup-shaped products 9 which are subjected to visual detection;

next, the first actuator 10 moves the cup-shaped products 9 that have not been detected by the first vision inspection device 5 into the first storage container 20, and the conveyor line 8 conveys the cup-shaped products 9 detected by the first vision inspection device 5;

next, the second visual inspection device 81 visually inspects the outside of the cup-shaped products 9 on the conveyor line 8, and the second actuator 30 moves the cup-shaped products 9 that have not been inspected by the second visual inspection device 81 into the second storage container 40;

finally, the conveyor line 8 conveys the cup-shaped products 9 which pass through two visual inspections.

The above disclosure is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, so that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
