[0014] A method for using a visual inspection device for production defects of ceramic cups is also provided, which is used to operate a visual inspection device for production defects of ceramic cups, comprising the following steps: S1: The two sets of rotating cup plates are rotated clockwise by the conveyor to separate the ceramic cups, and then the two sets of clamping plates are driven to rotate left and right by the servo motor to clamp and place the ceramic cups in the rotating cup plates on both sides to complete the inspection work; S2: When the servo motor drives the shaft to rotate, it drives the moving sleeve and the rack to slide back and forth on both sides, driving the gear and the cleaning wipe to rotate, and cooperates with the cylinder to drive up and down to wipe the bottom of the flipped ceramic cup; S3: When the round rod is driven to rotate back and forth by the round shaft, the airbag and the spring are pulled to extend and retract. When the airbag is squeezed, the gas inside the airbag can be blown out through the nozzle to blow the bottom of the ceramic cup under the defect detector on the right.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The ceramic cup is transported to the right side to the inside of the detection shell through the conveyor, and a set of rotating rods and rotating cup plates connected by servo motor 2 are driven to rotate, which drives the external synchronous belt to drive another set of rotating rods and rotating cup plates to rotate, so that the two sets of rotating cup plates rotate clockwise, and the rotating cup plate on the left drives the ceramic cup to move backward clockwise. The defect detector on the left performs a visual inspection of surface defects on the ceramic cup that is rotated to the bottom, and the other set of rotating cup plates will cooperate with the flipping component to rotate and transport the flipped ceramic cup to the rear position, so that another set of defect detectors will perform a visual inspection of defects on the bottom of the flipped ceramic cup again, and the inspected ceramic cup will be sent out from the right side of the detection shell, and the two sets of rotating cup plates will separate the conveyed ceramic cups and adjust them according to the inspection speed to ensure the inspection effect.

[0016] The servo motor drives the rotating shaft and the two groups of clamping pieces fixed on the outside to rotate, so that the two groups of clamping pieces rotate to the right, and the guide pin will slide to the right side near the middle direction of the fixed frame inside the guide groove, so as to place the clamped ceramic cup in the cup mouth of the rotating cup plate on the right side, complete the purpose of flipping, and facilitate the subsequent inspection of the bottom of the ceramic cup. The guide pin is driven to move to the right bottom of the guide groove and contact the slope (R), and the lifting limit frame slides upward along the slide groove, and the guide pin is pushed outward by the slope to one side of the limit frame plane, and the sliding limit frame falls and is restricted to one side of the guide pin. The guide pins on both sides move outward to push the two groups of clamping pieces to unfold. To complete the purpose of placing the cup, when the servo motor drives the two sets of clamping plates and guide pins to move to the left, the guide pins slide to the left bottom in the guide groove toward the edge of the fixed frame. Similarly, the two sets of guide pins slide along the slope, so that the two sets of clamping plates and guide pins move to the middle position of the fixed frame, and the two sets of unfolded clamping plates are brought together to clamp the ceramic cup (L) in the left rotating cup plate, completing the purpose of clamping and placing the two sides, which is convenient for detecting the bottom of the ceramic cup.

[0017] When the servo motor drives the rotating shaft to rotate, it will drive the fixed connecting plate and the circular shaft to rotate back and forth, causing the movable sleeve, the rack, and the sliding sleeve to slide back and forth along the left and right sides of the slide rail. The rack will drive the gear, the circular sleeve, and the cleaning wipe to rotate, and cooperate with the cylinder to drive the cleaning wipe to slide up and down, so that the cleaning wipe can wipe the bottom of the flipped ceramic cup to prevent impurities from sticking to the bottom of the ceramic cup and affecting defect detection.

[0018] When the round shaft drives the round rod to rotate reciprocatingly, the movable sleeve and the fixed plate are driven to move, pulling the airbag and the spring to retract and contract. When the airbag is squeezed, the gas inside the airbag can be blown out through the blow nozzle to blow the bottom of the ceramic cup under the defect detector on the right side to prevent impurities from effectively falling from the bottom of the ceramic cup after the wiping component is wiped.
