[0038] The present application provides a device for detecting the appearance of cigarettes, which uses a cigarette cleaning component to clean tobacco debris and dust on the surface of cigarettes and then uses a recognition camera to perform appearance detection, thereby avoiding false detection caused by tobacco debris and dust on the surface of cigarettes and improving the detection accuracy of the detection device.

[0039] like Figure 1 and 2 As shown, the cigarette appearance inspection device provided by the present application includes a controller 28, a conveyor platform 1, a cigarette cleaning assembly arranged above the conveyor platform in sequence along the conveying direction of the conveyor platform 1, a recognition camera 2, and a manipulator 3. A storage box 4 is fixed on the outer surface of the conveyor platform 1 at a position corresponding to the manipulator 3. The length direction of the cigarette is perpendicular to the conveying direction of the conveyor platform.

[0040] The cigarette cleaning assembly includes a U-shaped shell 5 fixed above the conveying platform 1, a cleaning cover 13 slidably arranged in the U-shaped shell 5 along the vertical direction, and a cleaning brush 12 slidably arranged in the U-shaped shell 5 along the horizontal direction. An in-position sensor is provided on the U-shaped shell 5 outside the upstream end of the cleaning cover 13.

[0041] The in-position sensor is connected to the controller 28 by signal, and the controller 28 is connected to the drive motor of the conveyor 1, the actuator of the sliding drive mechanism of the cleaning cover 13, the actuator of the sliding drive mechanism of the cleaning brush 12, the recognition camera 2 and the actuator of the robot 3 by signal.

[0042] As an embodiment, the in-position sensor is an infrared sensor. Figure 5 As shown, an infrared emitting device 26 and an infrared receiving device 27 are respectively provided at corresponding positions on two opposite sides of the U-shaped housing 5 .

[0043] When the cigarette moves to the bottom of the cleaning cover 13, the infrared signal emitted by the infrared transmitting device 26 will be blocked by the cigarette, and the infrared receiving device 27 will feed back the blocking signal to the controller 28. The controller 28 controls the conveying platform 1 to stop running, and controls the motor 21, the electric telescopic rod 10 and the fan 19 accordingly to clean the surface of the cigarette.

[0044] As an example, Figure 2-4As shown, a vertical electric telescopic rod 10 is provided on the inner side of one side of the U-shaped housing 5, a first slider 25 is provided in the middle of the electric telescopic rod 10, and a cleaning brush 12 is fixed to the lower end of the electric telescopic rod 10 through a cleaning plate 11. A first guide hole extending in a direction perpendicular to the conveying direction of the conveying platform 1 is provided on the cleaning cover 13, and the first slider 25 is slidably arranged in the first guide hole. The extension and contraction of the electric telescopic rod 10 drives the cleaning cover 13 to move upward or downward relative to the U-shaped housing 5. When the cleaning cover 13 drops to the lowest position, the cleaning cover 13 and the conveying platform 1 seal the cigarette in the space formed by the two.

[0045] As an embodiment, the first slider 25 is a T-shaped slider.

[0046] like Figure 2-4 As shown, a horizontal sliding drive mechanism is provided at the upper end of the electric telescopic rod 10. As an embodiment, the horizontal sliding drive mechanism includes a motor 21 fixed to the outer side of the upper portion of the U-shaped housing 5, and a rotating rod 6 arranged between two opposite sides of the U-shaped housing 5, and the output shaft of the motor 21 is coaxially connected to the rotating rod 6 through a connecting shaft 20.

[0047] A spiral slide groove 22 extending around the axis of the rotating rod 6 is provided on the outer periphery thereof, and a slide rod 8 is fixed to the upper end of the electric telescopic rod 10 through a connecting block 9, and a second slider 7 is provided at the upper end of the slider 8, and the second slider 7 is slidably arranged in the spiral slide groove 22. The rotation of the motor 21 drives the rotating rod 6 to rotate, so that the second slider 7 moves along the length direction of the cigarette under the limiting effect of the first guide hole and the guiding effect of the spiral slide groove 22, thereby sweeping off tobacco fragments and dust on the surface of the cigarette.

[0048] Preferably, a support plate 23 is provided in the middle of the slide rod 8 , and a second guide hole extending in a conveying direction perpendicular to the conveying platform 1 is provided on the support plate 23 , and the electric telescopic rod 10 passes through the second guide hole.

[0049] A third sliding block 24 is provided at a position on the sliding rod 8 corresponding to the second guide hole, and the third sliding block 24 is slidably disposed in the second guide hole.

[0050] As an embodiment, the third slider 24 is a cross-shaped slider, which slides in the support plate 23 to provide stable support for the slide rod 8, the support plate 23, the cleaning cover 13, the cleaning plate 11 and other mechanisms.

[0051] Preferably, a barrier net 14 is provided on the side of the cleaning cover 13. On this basis, the cigarette appearance detection device also includes a suction component. Figure 2 , 3 As shown in FIGS. 4 and 6 , the suction assembly includes a storage shell 17 fixed on the outer side of the conveying platform 1 , a closed transition shell 15 arranged on the outer side of the barrier net 14 , and a conduit 16 connecting the storage shell 17 and the closed transition shell 15 .

[0052] As an embodiment, a horizontal filter screen 18 is provided in the storage shell 17, and a through hole connected to the duct 16 is provided on the top surface of the storage shell 17. A fan 19 is provided below the filter screen 18 in the storage shell 17, and a plurality of ventilation holes are evenly distributed at the bottom of the storage shell 17. Through the design of the ventilation holes, a ventilation structure can be formed in the storage shell 17 without affecting the operation of the fan 19.

[0053] As an embodiment, the first side of the storage shell 17 is a cover plate 29, and the cover plate 29 is connected to the second side of the storage shell 17 through a buckle. The user can unfasten the buckle to remove the fan 19, collect and recycle the tobacco debris on the filter 18, and clean the dust.

[0054] Based on the above, the working principle of the cigarette appearance detection device of the present application is as follows:

[0055] The cigarette is placed on the conveying platform 1, and the cigarette enters the U-shaped housing 5 under the conveying platform 1. When the cigarette is located below the cleaning cover 13, the infrared signal emitted by the infrared emitting device 26 will be blocked by the cigarette, and the infrared receiving device 27 will feed back the blocking signal to the controller 28. The controller 28 will control the conveying platform 1 to stop running, and control the electric telescopic rod 10 to descend. The electric telescopic rod 10 descends and drives the cleaning cover 13 to descend. The cleaning cover 13 descends and covers the cigarette located in the cleaning cover 13. Then the controller 28 controls the motor 21 to operate, driving the rotating rod 6 to rotate. The rotating rod 6 rotates and drives the second slider 7 to slide on the spiral slide 22, driving the slider 8 to move back and forth on the support plate 23, and the electric telescopic rod 10 moves back and forth on the cleaning cover 13, thereby driving the cleaning brush 12 to clean the cigarette in the cleaning cover 13 back and forth, and sweeping away the broken tobacco and dust on the surface of the cigarette. Then the controller 28 starts the fan 19, which sucks the broken tobacco and dust in the cleaning cover 13 into the duct 16 through the closed transition shell 15, and finally enters the storage shell 17, and falls on the filter 18 for collection. The blocking net 14 can block the cigarettes to prevent the cigarettes from being sucked into the closed transition shell 15. At this time, the controller 28 controls the electric telescopic rod 10 to rise, starts the conveying platform 1 and shuts down the motor 21 and the fan 19. At this time, the cigarettes on the conveying platform 1 are photographed by the recognition camera 2 under the conveying of the conveying platform 1, and sent to the upper computer for appearance inspection and recognition. Then, the defective products are picked out by the manipulator 3 and placed in the storage box 4.
