An installation slot 4 is formed in the chassis 1. The good cigarette bin 301 and the defective cigarette bin 302 are placed into the chassis 1 through the installation slot 4. A handle 28 is formed at the front end of the good cigarette bin 301 and the defective cigarette bin 302, which is convenient for extraction.

[0024] The transport mechanism 311 is integrally inclined within the chassis 1. The transport mechanism 311 includes a first stepping motor 7, a second stepping motor 8, a feeding bin 9, a sheave shaft 10, a conveyor belt 11, an L-shaped stopper 12, a terminal stopper 13, a rolling flat plate 14, a support frame 15, a first support frame 16, and a second support frame 17. The support frame 15 is disposed within the chassis 1 and is fixedly connected to the chassis 1.

The first stepping motor 7 is used to drive the conveyor belt 11 to move. At the end with a higher inclined height of the first support frame 16, there is provided a feeding bin 9. On the chassis 1, there is provided a feeding port 18, and the top end of the feeding bin 9 is fixedly connected to the feeding port 18. At both ends of the feeding bin 9, there is respectively provided a second support frame 17, and the second support frame 17 is fixedly connected to the first support frame 16. The sheave shaft 10 is rotatably connected inside the feeding bin 9. The output shaft of the second stepping motor 8 is fixedly connected to the sheave shaft 10, and the second stepping motor 8 is fixedly connected to the second support frame 17. The second stepping motor 8 is used to drive the sheave shaft 10 to rotate. A number of L-shaped stoppers 12 are installed on the conveyor belt 11, and the number of L-shaped stoppers 12 is divided into two rows. Above the conveyor belt 11, there is provided a rolling flat plate 14, and the rolling flat plate 14 is fixedly connected to the first support frame 16. An empty groove 19 is provided on the rolling flat plate 14, and the L-shaped stopper 12 extends out from the empty groove 19. At the end with a lower inclined height of the first support frame 16, there is fixedly connected a terminal stopper 13. The operator puts the cigarettes to be inspected into the feeding bin 9 from the feeding port 18. The second stepping motor 8 will drive the sheave shaft 10 to rotate, so that the cigarettes will fall onto the conveyor belt 11 in sequence. Due to the overall inclination of the transport mechanism 311, the cigarettes will be supported by the L-shaped stoppers 12 after being on the conveyor belt 11. During the movement of the conveyor belt 11, the cigarettes are driven to make a uniform linear movement. At the same time, due to the frictional force of the rolling flat plate 14, the cigarettes will also make a uniform rotational movement around their own axes, which can enable the cigarettes to be detected in all directions.

[0025] Further, on both sides at the end close to the terminal stopper 13, there are provided side baffles 20, and the side baffles 20 are fixedly connected to the first support frame 16. Since the cigarettes will fall by themselves after the conveyor belt reaches a certain path, the side baffles 20 can effectively prevent the cigarettes from falling out of the rolling flat plate 14 during the rolling process.

[0026] At one end near the end stop 13, a third bracket 21 is provided. The third bracket 21 is fixedly connected to the transport mechanism 311. A sorting component 312 is installed on the third bracket 21. The sorting component 312 includes a third stepping motor 22, a gear 23, a rack 24, a pushing block 25 and a track 26. The third stepping motor 22 is fixedly connected to the third bracket 21. The gear 23 is fixedly connected to the output shaft of the third stepping motor 22. The gear 23 meshes with the rack 24. The track 26 is fixedly connected to the third bracket 21 and is located below the third stepping motor 22. The rack 24 slides within the track 26. Two pushing blocks 25 are fixedly connected below the rack 24. The two pushing blocks 25 are respectively located on the left and right sides of the end stop 13. By rotating the third stepping motor 22 to drive the gear 23 to rotate, the cigarette sticks on the end stop 13 are controlled to fall into the good cigarette bin 301 or the defective cigarette bin 302.

[0027] An area fiber optic sensor 27 is fixedly connected to the good cigarette bin 301 and the defective cigarette bin 302. When the cigarette sticks in one of the good cigarette bin 301 or the defective cigarette bin 302 reach the range of the area fiber optic sensor 27, the system sends a feedback signal and the alarm lamp 29 lights up to remind the staff to take away the storage box.

[0028] Working principle of the utility model: The staff neatly place the cigarette sticks to be inspected into the feeding bin 9. The second stepping motor 8 drives the grooved wheel shaft 10 to rotate, so that the cigarette sticks fall onto the conveyor belt 11 in sequence. When the cigarette sticks move linearly and rotate on the inclined rolling flat plate 14 and pass by the first cameras 303 arranged on both sides, the two end faces of the cigarette sticks are automatically imaged at the rhythm set by the system. When the cigarette sticks move and rotate under the light coaxial light source 309 and the second camera 304, the second camera 304 takes visual images of the cigarette rod part of the cigarette sticks at a predetermined time interval rhythm. Since the cigarette sticks are rotating uniformly by themselves, by setting an appropriate shooting time interval and a suitable moving speed, multiple images are taken during the process of the cigarette sticks rotating one week to complete the non-blind area imaging of the 360-degree circumferential area of the cigarette rod part of the cigarette sticks. The obtained images are processed by a program to judge and process various quality defects in the entire area of the end face and the circumferential face of the cigarette sticks to obtain the result of visual quality inspection. When the cigarette sticks are detected and judged by the visual program and roll to the end stop 13 of the rolling plane, if the cigarette sticks are detected and judged to be good products, the third stepping motor 22 is started to drive the gear 23 to rotate. The gear 23 drives the rack 24 to move to the left. The pushing block 25 fixed on the rack 24 pushes the cigarette sticks to the left. When the cigarette sticks are pushed to an appropriate position on the left receiving inclined plate 305, the cigarette sticks roll along this inclined plane and fall into the good cigarette bin 301. Similarly, when the cigarette sticks are detected and judged to be defective products, the third stepping motor 22 rotates in reverse. Through the transmission of the gear 23 and the rack 24, the pushing block 25 pushes the cigarette sticks to the right. There is also a receiving inclined plate 305 on the right end. The cigarette sticks roll along the inclined plane and fall into the defective cigarette bin 302 on the right side.
