[0030] Example: A conveying and turning device for detecting appearance defects of cigarette cases, please refer to Figures 1-5As shown in the figure, it includes a base 1 and a conveying component 2 installed on the top of the base 1. The conveying component 2 consists of two mounting shafts, four pulleys, two flat belts and a motor. Among them, the two mounting shafts are symmetrically and rotatably connected to the top of the base 1 on the left and right. The pulleys are symmetrically fixed and sleeved on the mounting shafts front and back. The flat belts are wound between the left and right pulleys. The motor is installed on the front left side of the base 1, and the end of the output shaft of the motor is fixedly connected to the front end of the left mounting shaft. In the middle of the top of the base 1, there is a fixedly connected mounting frame 3. In the middle of the top of the mounting frame 3, there is a high-definition camera 4 fixedly inserted. It also includes a lifting component, an electric rotating plate 8, an electric suction cup 9, a hollow column 10, an external gear ring 11, a spur gear 12, a driving motor 13 and a positioning component. In the middle of the top of the base 1, there is a lifting component. The lifting component is located below the high-definition camera 4. An electric rotating plate 8 is installed on the lifting component. In the middle of the electric rotating plate 8, there is a hollow column 10 rotatably inserted. Inside the hollow column 10, there is an electric suction cup 9. The electric suction cup 9 is located directly below the high-definition camera 4. On the upper part of the outer side of the hollow column 10, there is an external gear ring 11 fixedly sleeved along the circumference. On the left side of the electric rotating plate 8, there is a spur gear 12 rotatably connected. The spur gear 12 meshes with the external gear ring 11. At the bottom left side of the electric rotating plate 8, there is a driving motor 13 installed. The end of the output shaft of the driving motor 13 is fixedly connected to the middle of the bottom of the spur gear 12. The driving motor 13 is used to drive the spur gear 12 to rotate. The spur gear 12 drives the hollow column 10 to rotate through the external gear ring 11. The hollow column 10 drives the cigarette case to rotate through the electric suction cup 9 to perform a flip of the four side surfaces. A positioning component is arranged between the lifting component and the base 1. When the positioning component operates, the positioning component can position the position of the electric suction cup 9 so that the electric suction cup 9 is always directly below the high-definition camera 4.

[0031] Please refer to Figure 3 and Figure 4 As shown in the figure, the lifting component includes a guide rail 5, a movable seat 6, a movable frame 7 and an electric push rod 71. In the middle of the top of the base 1, there is a fixedly connected guide rail 5. A movable seat 6 is slidably connected to the guide rail 5. A movable frame 7 is vertically slidably connected to the movable seat 6. The movable frame 7 is rotatably connected to the right side of the electric rotating plate 8. When the movable frame 7 moves up and down, the movable frame 7 can drive the electric rotating plate 8 to move up and down. On the left side of the inner bottom of the movable seat 6, there is a fixedly connected electric push rod 71. The end of the telescopic rod of the electric push rod 71 is fixedly connected to the upper part of the movable frame 7.

[0032] Please refer to Figure 5 and Figure 6As shown, the positioning assembly includes a rotating shaft 14, a return spring 141, a one-way gear 142 and a guide assembly. The lower part of the movable seat 6 is symmetrically rotated with the rotating shaft 14, and the ends of the rotating shafts 14 on both sides are fixedly sleeved with one-way gears 142. The ends of the rotating shafts 14 on both sides are far away from each other and are respectively connected to the front and rear sides of the shaft of the electric rotating plate 8 through a synchronous belt assembly. A return spring 141 is connected between the lower part of the left side of the movable seat 6 and the left side of the guide rail 5. The top of the base 1 is provided with a guide assembly. When the guide assembly is in operation, the guide assembly can drive the one-way gear 142 to rotate forward; the guide assembly includes an elastic telescopic rod 143 and a rack 144, and the elastic telescopic rod 143 is symmetrically fixed to the top of the base 1, and the elastic telescopic rod 143 is composed of a sleeve, a round rod and a spring, wherein the sleeve is fixed to the top of the base 1, the round rod is slidably connected to the inner side of the sleeve, the spring is connected between the lower part of the round rod and the top inside the sleeve, and a rack 144 is fixed between the top ends of the elastic telescopic rods 143 on the left and right sides, and the rack 144 is located above the one-way gear 142.

[0033] First, start the intermittent reverse rotation of the conveying component 2. Place the cigarette case on the conveying component 2 from the right side. The intermittent reverse rotation of the conveying component 2 drives the cigarette case to move intermittently to the left. When the cigarette case moves to directly above the electric suction cup 9, start the high-definition camera 4 to take a picture of the front of the cigarette case. The taken picture is transmitted to the terminal for appearance defect detection. Then, start the electric push rod 71. The telescopic rod of the electric push rod 71 extends to drive the movable frame 7 to move upward. The upward movement of the movable frame 7 drives the one-way gear 142 to move upward through the rotating shaft 14. The upward movement of the one-way gear 142 meshes with the rack 144. The one-way gear 142 drives the rack 144 to move upward. The upward movement of the rack 144 drives the elastic telescopic rod 143 to move upward, causing the elastic telescopic rod 143 to extend. The upward movement of the movable frame 7 also drives the electric rotating plate 8 to move upward. The electric rotating plate 8 drives the electric suction cup 9 to move upward through the hollow column 10. The upward movement of the electric suction cup 9 contacts the cigarette case. Start the electric suction cup 9 to suck the cigarette case. Turn off the electric push rod 71, and the electric suction cup 9 stops moving upward. Subsequently, start the forward rotation of the electric rotating plate 8 to drive the hollow column 10 to rotate forward. The forward rotation of the hollow column 10 drives the cigarette case to rotate forward through the electric suction cup 9. The forward rotation of the cigarette case deviates from the position directly corresponding to the high-definition camera 4. At the same time, the forward rotation of the electric rotating plate 8 drives the rotating shaft 14 to rotate forward through the synchronous belt assembly. The forward rotation of the rotating shaft 14 drives the one-way gear 142 to rotate forward. The forward rotation of the one-way gear 142 moves leftward through the rack 144. The leftward movement of the one-way gear 142 drives the movable seat 6 to move leftward through the rotating shaft 14. The return spring 141 is compressed. The leftward movement of the movable seat 6 drives the movable frame 7 to move leftward. The movable frame 7 drives the electric rotating plate 8 to move leftward. The leftward movement of the electric rotating plate 8 drives the cigarette case to move leftward through the hollow column 10 and the electric suction cup 9, so that the cigarette case is directly corresponding to the high-definition camera 4. When the cigarette case rotates 90 degrees to a vertical state, turn off the electric rotating plate 8. At this time, start the high-definition camera 4 again to take a picture and detect the side of the cigarette case. Then, start the driving motor 13 to drive the spur gear 12 to rotate. The spur gear 12 drives the external gear ring 11 to rotate. The external gear ring 11 drives the hollow column 10 to rotate. The rotation of the hollow column 10 drives the cigarette case to rotate through the electric suction cup 9. When the cigarette case rotates 90 degrees to complete the flipping, turn off the driving motor 13, and the cigarette case stops rotating. The high-definition camera 4 takes a picture and detects the side of the cigarette case again. Repeat this process to complete the appearance defect detection of all four sides of the cigarette case. Then, start the forward rotation of the electric rotating plate 8 by 90 degrees again, so that the electric suction cup 9 drives the cigarette case to rotate 90 degrees forward to complete the turning over, making the front side face down and the turned-over side face up. At the same time, under the action of the one-way gear 142 and the rack 144, the cigarette case rotates forward and moves leftward at the same time to always be directly corresponding to the high-definition camera 4. Turn off the electric rotating plate 8. At this time, the cigarette case contacts the conveying component 2. Turn off the electric suction cup 9, and the electric suction cup 9 stops sucking the cigarette case. Start the reverse rotation of the electric rotating plate 8 to drive the electric suction cup 9 to reverse 180 degrees to reset through the hollow column 10. The reverse rotation of the electric rotating plate 8 drives the rotating shaft 14 to reverse through the synchronous belt assembly. Since the one-way gear 142 rotates in one direction,When the rotating shaft 14 rotates reversely for idling, it will not drive the one-way gear 142 to rotate reversely, and then the high-definition camera 4 can be started to take pictures and detect the back of the cigarette case, thus completing the final shooting of the cigarette case. Then, start the electric push rod 71 to drive the movable frame 7 to move downward. 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. Subsequently, 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 case after appearance defect detection to move to the left, and the next cigarette case moves to the left directly above the electric suction cup 9. According to the above operations, the appearance defects of the cigarette case can be comprehensively detected continuously. In this way, the front and back sides and the surrounding sides of the cigarette case can be flipped to complete the detection, thereby improving the comprehensiveness of appearance defect detection.

[0034] Please refer to Figure 7 and Figure 8As shown in the figure, the conveying and turning device for detecting the appearance defects of cigarette cases further includes an alignment component installed between the mounting frame 3 and the movable frame 7. The alignment component includes a fixed plate 15, a U-shaped rod 151, an adjusting screw 1511, a fixed frame 152, an alignment plate 153, a bidirectional screw 154, a connecting spring 1541 and a triggering component. Fixed plates 15 are symmetrically and fixedly connected to the lower part of the inner side of the mounting frame 3 in the front and rear. U-shaped rods 151 are symmetrically and slidably connected to the left and right on both the front and rear fixed plates 15. Connecting springs 1541 are connected between the two ends of the U-shaped rod 151 and the outer side of the fixed plate 15. Adjusting screws 1511 are threadedly connected to the upper ends of the U-shaped rods 151 on the left and right. A fixed frame 152 is rotatably sleeved between the adjusting screws 1511 on the left and right. Alignment plates 153 are symmetrically and slidably connected to the left and right inside the fixed frame 152. The alignment plates 153 on the front and rear sides correspond to each other. When the alignment plate 153 contacts the cigarette case, the alignment plate 153 can align and position the cigarette case. A bidirectional screw 154 is rotatably connected between the left and right sides of the fixed frame 152. The threads on the left and right sides of the bidirectional screw 154 are opposite. The bidirectional screw 154 is threadedly connected to the alignment plate 153. A triggering component is arranged between the fixed plate 15 and the movable frame 7. When the triggering component operates, the triggering component can drive the U-shaped rod 151 to move; the triggering component includes a sliding rod 155, a contact wheel 1551, a triangular block 156 and a triggering block 157. A sliding rod 155 is horizontally slidably connected to the side where the front and rear fixed plates 15 are close to each other. Triggering blocks 157 are symmetrically and fixedly connected to the left and right on the sliding rod 155. The right side of the triggering block 157 is an inclined surface. When the triggering block 157 moves to the right and contacts the U-shaped rod 151, the triggering block 157 can drive the U-shaped rod 151 to move inward. Triangular blocks 156 are symmetrically and fixedly connected to the upper part of the right side of the movable frame 7. The triangular blocks 156 correspond to the sliding rod 155. When the triangular blocks 156 move up and down, the triangular blocks 156 can drive the sliding rod 155 to move to the right. Contact wheels 1551 are rotatably connected to the ends where the front and rear sliding rods 155 are close to each other. The contact wheels 1551 correspond to the triangular blocks 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.

[0035] When the cigarette case is placed on the conveying assembly 2, turning the adjusting screw 1511 drives the front and rear fixed frames 152 to move synchronously in and out. The fixed frame 152 drives the front and rear deviation rectifying plates 153 to move synchronously in and out. When the deviation rectifying plates 153 move in and out to a position suitable for rectifying the length direction of the cigarette case, stop turning the adjusting screw 1511. Then turn the bidirectional screw 154 to drive the left and right deviation rectifying plates 153 to move in and out. When the deviation rectifying plates 153 move in and out to a position suitable for rectifying the width direction of the cigarette case, stop turning the bidirectional screw 154. When the conveying assembly 2 drives the cigarette case to move leftward to directly above the electric suction cup 9, the cigarette case is located between the four deviation rectifying plates 153. When the electric push rod 71 is activated to drive the movable frame 7 to move upward, the upward movement of the movable frame 7 drives the triangular block 156 to move upward. The upward movement of the triangular block 156 contacts the contact wheel 1551. The triangular block 156 drives the sliding rod 155 to move rightward through the contact wheel 1551. The rightward movement of the sliding rod 155 drives the trigger block 157 to move rightward. The rightward movement of the trigger block 157 contacts the U-shaped rod 151. The trigger block 157 drives the front and rear U-shaped rods 151 to move inward. The connecting spring 1541 is compressed. The U-shaped rod 151 drives the front and rear fixed frames 152 to move inward through the adjusting screw 1511. The fixed frame 152 drives the front and rear deviation rectifying plates 153 to move inward. The front and rear deviation rectifying plates 153 move inward to contact the cigarette case. The deviation rectifying plates 153 rectify and position the cigarette case, so that the cigarette case is in an accurate detection position. As the triangular block 156 continues to move upward, the triangular block 156 disengages from the contact wheel 1551, and the limit on the sliding rod 155 is stopped. Due to the action of the connecting spring 1541, the front and rear U-shaped rods 151 move outward and reset, driving the sliding rod 155 to move leftward and reset through the trigger block 157. The U-shaped rod 151 drives the deviation rectifying plates 153 to move outward and reset through the adjusting screw 1511 and the fixed frame 152. The deviation rectifying plates 153 reset and disengage from the cigarette case. Subsequently, the electric suction cup 9 sucks and fixes the rectified and positioned cigarette case. When the electric push rod 71 drives the movable frame 7 to move downward and reset, the movable frame 7 drives the triangular block 156 to move downward and reset. The downward movement of the triangular block 156 slides over the contact wheel 1551. In this way, the phenomenon of the cigarette case being skewed can be prevented from affecting the accuracy of subsequent detection of the four side surfaces, thereby further improving the accuracy of detecting the four side surfaces of the cigarette case.

[0036] Please refer to Figure 9 As shown, the conveying and turning device for detecting the appearance defects of cigarette cases further includes a lighting lamp 16. The lighting lamp 16 is fixedly connected to the upper part inside the mounting frame 3. When the lighting lamp 16 is activated, the lighting lamp 16 can illuminate the cigarette case.

[0037] When the cigarette case moves to directly below the high-definition camera 4, turn on the lighting lamp 16. The lighting lamp 16 illuminates the cigarette case, and the high-definition camera 4 takes a picture of the illuminated cigarette case. After the appearance defect detection of the cigarette case is completed, turn off the lighting lamp 16. In this way, the appearance picture of the cigarette case taken by the high-definition camera 4 can be clearer, thereby improving the detection effect.

[0038] Finally, it is necessary to note that the above content is only used to help understand the technical solution of the present invention and should not be construed as a limitation on the protection scope of the present invention; non-essential improvements and adjustments made by those skilled in the art based on the above content of the present invention all fall within the scope claimed by the present invention.
