[0048] like Figure 1-Figure 7 As shown, the automatic cigarette appearance quality image acquisition device provided in this embodiment includes: a device body, wherein the device body is provided with a cigarette distribution component, a cigarette conveying component, a detection table moving component, a cigarette top visual detection component, a cigarette end visual detection component 4 and a cigarette collection component 7, wherein:

[0049] The cigarette dividing assembly is located at the feed end, and is used to receive the cigarettes to be tested and separate the cigarettes to be tested into individual cigarettes 9;

[0050] The cigarette conveying assembly is used to convey individual cigarettes 9 between the detection table moving assembly and the cigarette distributing assembly or the cigarette collecting assembly, and to take and place individual cigarettes 9;

[0051] The detection platform moving component is used to move the detection platform;

[0052] The cigarette top visual detection component is used to collect images of the outer circumference of the cigarette 9;

[0053] The cigarette end visual detection component 4 is used to collect images of the cigarette end 9;

[0054] The cigarette collecting assembly 7 is located at the discharge end and is used to collect the cigarettes 9 that have completed image acquisition.

[0055] Among them, such as Figure 1 and Figure 2 As shown, the device body includes a frame 11 and a housing 12 disposed on the frame 11. The frame 11 and the housing 12 constitute the main frame of the device for automatically collecting cigarette appearance quality images, supporting all components.

[0056] Furthermore, the automatic cigarette appearance quality image acquisition device further includes a cigarette appearance quality analysis module, which is connected to the cigarette top visual detection component and the cigarette end visual detection component 4 and is used to obtain a cigarette appearance quality analysis result based on the images captured by the cigarette top visual detection component and the cigarette end visual detection component 4, wherein the cigarette appearance quality analysis result includes a qualified or unqualified result.

[0057] like Figure 2 and Figure 7 As shown, the cigarette collection assembly 7 includes: a normal cigarette collection box 71 and a defective cigarette collection box 72. The normal cigarette collection box 71 is used to collect qualified cigarettes, and the defective cigarette collection box 72 is used to collect unqualified cigarettes.

[0058] Furthermore, if Figure 2 As shown, the automatic cigarette appearance quality image acquisition device also includes an electrical control system 8, which is disposed within the device body and connected to the cigarette sorting assembly, the cigarette conveying assembly, the inspection platform moving assembly, the cigarette top visual inspection assembly, and the cigarette end visual inspection assembly 4, and is used to control the operation of the cigarette sorting assembly, the cigarette conveying assembly, the inspection platform moving assembly, the cigarette top visual inspection assembly, and the cigarette end visual inspection assembly 4. In one embodiment of the present invention, the electrical control system 8 is a PLC control system.

[0059] During operation, the cigarettes to be inspected are manually placed into the cigarette sorting assembly; the cigarette sorting assembly automatically disperses the cigarettes 9 and absorbs a single cigarette 9, and then rotates the cigarette to stop at the feeding port; the cigarette conveying assembly absorbs the cigarette 9 from the feeding port and conveys the cigarette 9 to the inspection platform moving assembly; the cigarette top visual inspection assembly is triggered to take a photo and collect an image of the currently exposed arc surface of the cigarette 9 according to the number of shots set by the system. After the shooting and collection are completed, the cigarette conveying assembly quickly rotates the cigarette 180 degrees, and turns the photographed arc surface of the cigarette 9 downward, and the inspection platform moving assembly rises to a position directly below the cigarette 9, and the cigarette conveying assembly disconnects the vacuum to release the cigarette. At the same time, the inspection platform moving assembly quickly absorbs the cigarette, and then the inspection platform moving assembly descends to the inspection position. At this time, the uninspected arc surface of the cigarette faces upward, and the cigarette top visual inspection assembly is triggered again The component takes a photo and collects an image of the currently exposed curved surface of the cigarette according to the number of shots set by the system; after the shooting and collection are completed, the detection platform moving component rotates the detection platform 33 90 degrees clockwise, so that one end of the cigarette is facing the end detection visual system 4. At this time, the cigarette is concentric with the lens of the end detection visual system 4, triggering the end detection visual system 4 to take a photo and collect an image of the current end face of the cigarette according to the number of shots set by the system; after the shooting and collection are completed, the detection platform moving component rotates the detection platform 33 180 degrees counterclockwise, so that the other end of the cigarette is facing the end detection visual system 4, triggering the end detection visual system 4 to take a photo and collect an image of the current end face of the cigarette according to the number of shots set by the system, and after the shooting and collection are completed, the detection platform moving component rotates the detection platform 33 90 degrees clockwise, so that the cigarette is in the initial placement state. Afterwards, the cigarette appearance quality analysis module assesses the appearance quality of the current cigarette 9 based on the captured images. If a cigarette 9 exhibits any defects, such as punctures, steel stamp stains, exposed drowning, bubbles, indentations, damaged cuts, extrusion deformation, contact, hollow ends, uncleanness, wrinkles, or warped edges, it is deemed unqualified. The cigarette conveyor assembly picks up the cigarette 9 and moves it to the top of the defective cigarette collection box 72. The vacuum is disconnected and the cigarette 9 falls into the defective cigarette collection box 72. Similarly, if a cigarette 9 is deemed qualified, the cigarette conveyor assembly picks it up and moves it to the top of the normal cigarette collection box 71. The vacuum is disconnected and the cigarette falls into the normal cigarette collection box 71. This completes one inspection. The cycle continues until all cigarettes received by the cigarette distribution assembly have been inspected. The system then issues a signal to alert personnel to replenish cigarettes or shut down the machine.

[0060] Furthermore, if Figure 1 As shown, the cigarette distribution assembly includes:

[0061] The cigarette storage bin 61 is used to store cigarettes to be tested;

[0062] The cigarette divider 62, which uses a servo cam dividing mechanism, is used to separate the cigarettes to be tested into individual cigarettes. It is also used to extract individual cigarettes and transfer them to the feed port through servo positioning. The feed port is located below the cigarette storage bin 61 and corresponds to the starting position of the cigarette dividing assembly.

[0063] The cigarette arranging mechanism 63 is used to align the end faces of multiple cigarettes.

[0064] Furthermore, if Figure 4 As shown, the cigarette divider 62 includes a multi-divided camshaft 621, and the multi-divided camshaft 621 is connected to a first servo motor 622 for driving the multi-divided camshaft to rotate 621. Specifically, the multi-divided camshaft 621 is connected to the first servo motor 622 through two synchronous pulleys 625 and a synchronous belt 624 mounted on the two synchronous pulleys 625. When the first servo motor 622 is running, the synchronous pulley 625 and the synchronous belt 624 transmit the power of the output shaft of the first servo motor 622 to the multi-divided camshaft 621, so that the multi-divided camshaft 621 and the output shaft of the first servo motor 622 rotate together at a preset speed ratio; the outer peripheral surface of the multi-divided camshaft 621 is provided with a cigarette adsorption groove 623 along the axial direction, and a porous negative pressure adsorption device is provided in the cigarette adsorption groove 623. During operation, the porous negative pressure adsorption device can disperse the cigarettes 9 and absorb each cigarette 9 individually. The multi-dividing cam shaft 621 rotates in a directional and uniform speed, moving the cigarettes to the feeding port. The cigarettes are positioned directly above the detection platform moving component. After detecting that the detection platform moving component is in place, the porous negative pressure adsorption device of the cigarette distributor 62 turns off the negative pressure, causing the cigarettes to fall onto the detection platform moving component.

[0065] like Figure 3 As shown, the cigarette arrangement mechanism 63 includes a movable baffle 631. Two sets of staggered pulleys 632 are disposed at the bottom of the movable baffle 631. The ends of the two sets of pulleys 632 are tangential to the sides of the cigarette storage bin 61, allowing the movable baffle 631 to fit tightly against the cigarette storage bin 61. The movable baffle 631 helps to align the cigarettes within the cigarette storage bin 631, with their ends aligned. Once a cigarette is placed into the inspection port, the cigarette arrangement mechanism 63 allows the movable baffle to align the cigarettes, facilitating their removal, due to the tight fit between the movable baffle and the cigarette storage bin 61.

[0066] In practice, cigarettes to be tested are manually placed into the cigarette storage bin 61, where they are aligned end-to-end by the cigarette sorting mechanism 63. The testing process then begins. The cigarette dispenser 62 automatically disperses the cigarettes at a set frequency, extracting individual cigarettes and, through servo positioning, rotating and stopping them at the feed port.

[0067] Furthermore, if Figure 1 and Figure 4 As shown, the detection platform moving assembly is installed at the center of the device body, and the detection platform moving assembly includes:

[0068] The detection table 33 is used to carry cigarettes, and a vacuum adsorption device is provided at the detection position of the detection table 33;

[0069] A second servo indexing mechanism 31 is provided below the detection platform 33 and is used to drive the detection platform 33 to rotate a preset angle;

[0070] The lifting mechanism 32 is provided between the second servo indexing mechanism 31 and the detection platform 33 and is used to adjust the height of the detection platform 33 .

[0071] Among them, such as Figure 4 As shown, the second servo indexing mechanism 31 is connected to a second servo motor 34 for driving the second servo indexing mechanism 31 to rotate. The lifting mechanism 32 is a lifting cylinder. The positioning and adjustment of the cigarettes to be tested on the testing table 33 are achieved through the second servo indexing mechanism 31 and the lifting mechanism 32.

[0072] Furthermore, if Figure 1 and Figure 4 As shown, the cigarette conveying assembly includes:

[0073] A servo conveyor mechanism 21 is connected to the cigarette dispensing assembly and is used to horizontally move cigarettes and position them. The servo conveyor mechanism 21 is located on the cigarette conveying path and is connected to a third servo motor 24 for driving the servo conveyor mechanism 21 to move in a horizontal linear direction.

[0074] a first servo indexing mechanism 22, disposed on the servo conveying mechanism 21 and movable with the servo conveying mechanism 21 for rotating cigarettes; the first servo indexing mechanism 22 is connected to a fourth servo motor 25 for driving the first servo indexing mechanism 22 to rotate;

[0075] The vacuum pick-up mechanism 23 is mounted on the first servo indexing mechanism 22 and rotates with it, absorbing and releasing cigarettes. Furthermore, the vacuum pick-up mechanism 23 incorporates a vacuum negative pressure sensor, located near the suction port, to detect whether cigarettes are properly absorbed. The cigarette dispensing assembly, located between the cigarette storage bin 61 and the detection platform 33, facilitates the transfer and rotation of cigarettes.

[0076] In a specific implementation, the servo conveyor mechanism 21 rapidly moves the vacuum picker mechanism 23, integrated with the first servo indexing mechanism 22 mounted thereon, and positions the vacuum picker mechanism 23 at the feed port of the cigarette sorting assembly. The vacuum picker mechanism 23 then draws cigarettes from the feed port. Once the vacuum negative pressure sensor detects the adsorption of the cigarettes, the servo conveyor mechanism 21 moves again and positions itself at the inspection platform 33. Specifically, the third servo motor 24 drives the servo conveyor mechanism 21 in a horizontal, linear direction, and the photoelectric sensor and mechanical limiter structure position the servo conveyor mechanism 21 at the inspection platform 33.

[0077] In one embodiment of the present invention, after the visual inspection component on the top of the cigarette completes taking a photo and collecting an image of the currently exposed arc surface of the cigarette, the first servo indexing mechanism 22 quickly rotates 180 degrees and stops the photographed arc surface of the cigarette facing down directly above the inspection platform 33; the lifting mechanism 32 lifts the inspection platform 33 so that the center of the cigarette placement slot of the inspection platform 33 coincides with the center of the vacuum feeding structure 23. At this time, the vacuum feeding mechanism 23 disconnects the vacuum and releases the cigarette. At the same time, the vacuum in the cigarette placement slot of the inspection platform 33 is turned on, and the cigarette is quickly adsorbed. After the vacuum negative pressure sensor detects the adsorption of the cigarette, the lifting mechanism 32 descends to the inspection position, wherein the inspection position is located at a fixed height after the inspection platform 33 is lowered. At this time, the undetected arc surface of the cigarette faces upward, triggering the visual inspection component on the top of the cigarette again to take a photo and collect an image of the currently exposed arc surface of the cigarette according to the number of shots set by the system, completing 360-degree image information acquisition of the cigarette. After the shooting and collection is completed, the second servo indexing mechanism 31 rotates 90 degrees clockwise, so that one end of the cigarette is facing the cigarette end visual detection component 4. At this time, the cigarette and the lens of the cigarette end visual detection component 4 are concentric, triggering the cigarette end visual detection component 4, and photographing the current end face of the cigarette and collecting the image according to the number of shots set by the system. After the shooting and collection is completed, the second servo indexing mechanism 31 rotates 180 degrees counterclockwise, so that the other end of the cigarette is facing the cigarette end visual detection component 4, triggering the cigarette end visual detection component 4, and photographing the current end face of the cigarette and collecting the image according to the number of shots set by the system.

[0078] Furthermore, if Figure 1 As shown, the cigarette top visual detection assembly includes a first cigarette top visual detection assembly 51 and a second cigarette top visual detection assembly 52 located above the detection platform 33 and symmetrically distributed along the center of the detection platform 33, wherein:

[0079] like Figure 5As shown, the first cigarette top visual detection component 51 and the second cigarette top visual detection component 52 respectively include a top visual camera 53 and a top visual light source 54 arranged on both sides of the top visual camera 53, and the top visual light source 54 is a bar light source. Among them, the top visual cameras 53 corresponding to the first cigarette top visual detection component 51 and the second cigarette top visual detection component 52 are both high-definition cameras. In the present invention, the first cigarette top visual detection component 51 and the second cigarette top visual detection component 52 are respectively composed of independent cameras and light sources, and the angles of the cameras and light sources can be fine-tuned to meet the detection needs. In a specific implementation, the first cigarette top visual detection component 51 and the second cigarette top visual detection component 52 can take pictures and collect images of the currently exposed curved surface of the cigarette according to the number of shots set by the system.

[0080] Furthermore, if Figure 6 As shown, the cigarette end visual inspection assembly 4 includes an end vision camera 41 located on one side of the inspection platform 33. The front face of the end vision camera 41 is provided with an annular end vision light source 42. The end vision camera 41 is a high-definition camera. During actual inspection, the distance between the end vision camera 41 and the end vision light source 42 relative to the cigarette end face is adjustable to achieve the roundness contour accuracy of the cigarette end face image. The cigarette end visual inspection assembly 4 enables image capture of the cigarette end face and the tobacco end face.

[0081] The cigarette storage bin 61 of the present invention's cigarette sorting assembly utilizes a servo cam sorting mechanism, and the cigarette sorter 62 is equipped with a multi-porous negative pressure suction device. During operation, it disperses cigarettes, extracts individual cigarettes, and then transfers them to the feed port in a directional and positioned manner.
