[0031] First, the conveying assembly 2 is started to intermittently reverse, and the cigarette box is placed on the conveying assembly 2 from the right side. The intermittent reversal of the conveying assembly 2 drives the cigarette box to intermittently move to the left. The cigarette box moves to the left to just above the electric suction cup 9, and the high-definition camera 4 is started to take a picture of the front of the cigarette box. The taken picture is transmitted to the terminal for appearance defect detection, and then the electric push rod 71 is started. The telescopic rod of the electric push rod 71 is extended to drive the movable frame 7 to move upward. The movable frame 7 moves upward and drives the one-way gear 142 to move upward through the rotating shaft 14. The one-way gear 142 moves upward and meshes with the rack 144. The one-way gear 142 drives the rack 144 to move upward. The rack 144 moves upward and drives the elastic telescopic rod 143 to move upward, so that the elastic telescopic rod 143 is extended, and the movable frame 7 moves upward. The movement also drives the electric rotating plate 8 to move upward, and the electric rotating plate 8 drives the electric suction cup 9 to move upward through the hollow column 10, and the electric suction cup 9 moves upward and contacts the cigarette box, and the electric suction cup 9 is started to suck the cigarette box, and the electric push rod 71 is closed, and the electric suction cup 9 stops moving upward, and then the electric rotating plate 8 is started to rotate forward to drive the hollow column 10 to rotate forward, and the hollow column 10 rotates forward through the electric suction cup 9 to drive the cigarette box to rotate forward, and the cigarette box rotates forward and deviates from the position corresponding to the high-definition camera 4. At the same time, the electric rotating plate 8 rotates forward through the synchronous belt assembly to drive the rotating shaft 14 to rotate forward, and the rotating shaft 14 rotates forward to drive the one-way gear 142 to rotate forward, and the one-way gear 142 rotates forward to move to the left through the rack 144, and the one-way gear 142 moves left and drives the movable seat 6 to move left through the rotating shaft 14, and resets. The spring 141 is compressed, the movable seat 6 moves to the left, driving the movable frame 7 to move to the left, the movable frame 7 drives the electric rotating plate 8 to move to the left, the electric rotating plate 8 moves to the left, and drives the cigarette box to move to the left through the hollow column 10 and the electric suction cup 9, so that the cigarette box is exactly corresponding to the high-definition camera 4. When the cigarette box rotates 90 degrees to a vertical state, the electric rotating plate 8 is closed, and the high-definition camera 4 is started again to shoot and detect the side of the cigarette box, and then the drive motor 13 is started to drive the spur gear 12 to rotate, the spur gear 12 drives the outer gear ring 11 to rotate, and the outer gear ring 11 drives the hollow column 10 to rotate, and the hollow column 10 rotates through the electric suction cup 9 to drive the cigarette box to rotate. When the cigarette box rotates 90 degrees to complete the flip, the drive motor 13 is closed, the cigarette box stops rotating, and the high-definition camera 4 takes pictures of the cigarette box again. The side of the cigarette box is photographed for inspection, and this process is repeated to photograph the four sides of the cigarette box to complete the appearance defect inspection, and then the electric rotating plate 8 is started again to rotate forward 90 degrees, so that the electric suction cup 9 drives the cigarette box to rotate forward 90 degrees to complete the flip, so that the front side faces down and the flip side faces up. At the same time, under the action of the one-way gear 142 and the rack 144, the cigarette box moves to the left while rotating forward and has been corresponding to the high-definition camera 4. The electric rotating plate 8 is closed. At this time, the cigarette box contacts the conveying component 2, and the electric suction cup 9 is closed. The electric suction cup 9 stops sucking the cigarette box, and the electric rotating plate 8 is started to reverse and drive the electric suction cup 9 to reverse 180 degrees and reset through the hollow column 10. The electric rotating plate 8 is reversed and drives the rotating shaft 14 to reverse through the synchronous belt assembly. Since the one-way gear 142 rotates in one direction,The rotating shaft 14 is reversed and idled without driving the one-way gear 142 to reverse, so the high-definition camera 4 can be started to shoot and detect the back of the cigarette box, and the final shooting of the cigarette box is completed. The electric push rod 71 is started to drive the movable frame 7 to move downward, and the movable frame 7 drives the electric rotating plate 8 to move downward. The electric rotating plate 8 drives the electric suction cup 9 to move downward and reset through the hollow column 10. The movable frame 7 also drives the one-way gear 142 to move downward through the rotating shaft 14. Due to the action of the elastic telescopic rod 143, the elastic telescopic rod 143 drives the rack 144 to move downward and reset. The one-way gear 142 continues to move downward and disengages from the reset rack 144. Due to the action of the reset spring 141, the movable seat 6 moves to the right and resets, driving the electric rotating plate 8 to move to the right and reset through the movable frame 7, which also drives the electric suction cup 9 to move to the right and reset. The movable seat 6 also drives the one-way gear 142 to move to the right and reset through the rotating shaft 14. Then the conveying component 2 drives the cigarette box after the appearance defect inspection to move to the left, and moves the next cigarette box to the left to just above the electric suction cup 9. According to the above operation, the appearance defects of the cigarette box can be fully inspected. In this way, the front and back sides and the surrounding sides of the cigarette box can be turned over to complete the inspection, thereby improving the comprehensiveness of the appearance defect inspection.

The trigger block 157 is fixedly connected to the slide bar 155 symmetrically on the left and right. The right side of the trigger block 157 is an inclined surface. When the trigger block 157 moves to the right and contacts the U-shaped rod 151, the trigger block 157 can drive The U-shaped rod 151 moves inward, and a triangular block 156 is symmetrically fixed to the upper front and rear sides of the right side surface of the movable frame 7. The triangular block 156 corresponds to the sliding rod 155. When the triangular block 156 moves up and down, the triangular block 156 can drive the sliding rod 155 to move to the right. The ends of the sliding rods 155 on the front and rear sides that are close to each other are rotatably connected with contact wheels 1551, and the contact wheels 1551 correspond to the triangular block 156. The contact wheels 1551 can reduce the friction between the sliding rod 155 and the triangular block 156, so that the triangular block 156 can drive the sliding rod 155 to move more smoothly.

[0033] When the cigarette box is placed on the conveying assembly 2, the adjusting screw 1511 is twisted and rotated to drive the front and rear fixed frames 152 to move inward and outward synchronously, and the fixed frames 152 drive the front and rear correcting plates 153 to move inward and outward synchronously. When the correcting plates 153 move inward and outward to a suitable position for correcting the cigarette box in the length direction, the adjusting screw 1511 is stopped, and the bidirectional screw 154 is twisted and rotated to drive the left and right correcting plates 153 to move inward and outward. When the correcting plates 153 move inward and outward to a suitable position for correcting the cigarette box in the width direction, the bidirectional screw 154 is stopped. When component 2 drives the cigarette box to move to the left to the top of the electric suction cup 9, the cigarette box is between the four correcting plates 153. When the electric push rod 71 is started to drive the movable frame 7 to move upward, the movable frame 7 moves upward to drive the triangular block 156 to move upward. The triangular block 156 moves upward and contacts the contact wheel 1551. The triangular block 156 drives the slide bar 155 to move to the right through the contact wheel 1551.
