Description

Technical Field

[0001] The utility model relates to the technical field of cigarette appearance detection, in particular to an auxiliary device for detecting the appearance of cigar cigarettes. Background Art

[0002] During the production and processing of cigar cigarettes, more or less defective cigarettes will appear. If unqualified cigarettes flow into the market, it will have a very serious impact on the enterprise's reputation. Before there was no targeted detection device, in most cases, manual sampling inspection was used to detect cigarettes, and this method of manual sampling inspection had many limitations, such as: lag, lack of comprehensiveness, etc. Although this method reduces the possibility of defective cigarettes flowing into the market, it will still miss a small number of defective cigarettes. The existing image acquisition and analysis technology can well analyze images, including accuracy, etc., but the image acquisition is not comprehensive, and some problems still exist. Therefore, there is an urgent need for an auxiliary device that can comprehensively collect the surface information of cigarettes. Content of the Utility Model

[0003] The purpose of the utility model is to provide an auxiliary device for detecting the appearance of cigar cigarettes. By collecting image information of different parts during the transmission of cigarettes, it helps to process and obtain a whole cigarette photo, and thus assists in achieving better accuracy in cigarette detection.

[0004] To achieve the above purpose, the utility model is realized through the following technical solutions.

[0013] Furthermore, it further includes a transport table forming an upper cavity and a lower cavity. Along the transport table, the conveying mechanism forms a conveying trajectory that conveys from bottom to top, and the conveying trajectory is an L-shaped structure passing through the transport table.

Detailed implementation manners

[0031] The present utility model will be described in detail below with reference to the embodiments shown in the drawings. It should be noted that these embodiments are not intended to limit the present utility model, and any equivalent transformation or substitution in terms of function, method, or structure made by those of ordinary skill in the art based on these embodiments shall fall within the protection scope of the present utility model.

[0032] Referring to the attached Figure 1-8 As shown, the cigarette appearance detection auxiliary device for cigars in this embodiment includes a conveying mechanism 100 that forms a conveying track. Then, a plurality of fixing mechanisms for fixing cigars 200 are provided on the conveying mechanism 100. Furthermore, a plurality of cigarette sticks, mainly cigars, can be fixed on the conveying mechanism for synchronous conveying.

[0033] Specifically, the conveying track includes a first track 110 in the first direction and a second track 120 in the second direction, and the second track 120 is connected to the first track 110; at this time, the two tracks form a relatively complete transportation track and have transportation in different directions respectively.

[0034] At this time, in order to ensure collection in different directions, and further, a first camera group 130 and a second camera group 140 are respectively located on the first track 110 and the second track 120. A plurality of groups of lighting components 310 are provided on the outer periphery of each camera group 300. The plurality of groups of lighting components 310 form an arc-shaped light area, and the camera group obtains image information of at least the upper half and the lower half respectively through the arc-shaped light area. In this embodiment, the structures of the two camera groups are exactly the same, which is convenient for production. They are only assembled at different positions respectively, and then photos of cigarette sticks at different positions and directions are collected.

[0035] The following is introduced in combination with each specific structural component.

[0036] First, for the camera component 300.

[0037] In this embodiment, an assembly shell 320 forming a necking cavity is further included. The narrowest part of the necking cavity forms an opening 330. The plurality of groups of lighting components 310 are evenly distributed at the opening 330 along the arc direction. Specifically, the assembly shell is provided with a bottom plate, and then a detection box plug for subsequent matching with the detection component is added to the bottom plate. Then at least two cameras are arranged in the necking cavity, thereby ensuring multi-angle collection. At the same time, each camera passes through the gap between adjacent lighting group components to form a shooting direction towards the distance. At this time, the cigarette stick is just located in this shooting direction, thereby providing a basis for forming a complete image subsequently.

[0038] Specifically, each camera group includes two cameras 340 and three groups of lighting components 310. Then the three groups of lighting components 310 are arranged along the outer side of the camera group, respectively located at the two ends and the middle position of the arc track. At this time, the lighting components form a relatively large light area, which is much larger than the area of the opening 330 of the necking cavity, and then its projection covers the opening.

[0039] Preferably, the plurality of groups of lighting components 310 form a fan-shaped area with a radian of 110° to 150° at the opening 330, and the height of the fan-shaped area is not less than 12 mm. At this time, at the opening, the lighting components have a certain height.

[0040] In this embodiment, the length, width, and height of the lighting component formed by each group of light source components are: 192 mm * 20 mm * 12 mm, and the radian formed by the three groups of light sources is 140°. In this embodiment, the lighting component is specifically formed by arranging a plurality of lights in a lighting shell, and then an arc-shaped connecting piece is arranged at the opening, and each lighting component is installed along the arc-shaped connecting piece.

[0041] Secondly, the assembly of the entire conveying mechanism will be introduced.

[0042] In order to save space, the transportation platform 400 that forms the upper cavity 410 and the lower cavity 420 is directly utilized. Along the transportation platform 400, the conveying mechanism 100 forms a conveying trajectory that conveys from bottom to top. Specifically, the conveying trajectory is an L-shaped structure that passes through the transportation platform 400. At this time, the conveying trajectory has two directions and is perpendicular, thereby avoiding the problem of being worried that the lower half of the cigarette is not easily obtained.

[0043] In the transportation platform 400, the first camera group 130 and the second camera group 140 are respectively located in the upper cavity 410 and the lower cavity 420, and the second camera group 140 is arranged close to the outside of the transportation platform 400. At this time, the second camera group is relatively arranged outside, so that it is both inside the transportation platform, but the image outside can be obtained when taking pictures.

[0044] It further includes a partition board 430 that divides to form the upper cavity 410 and the lower cavity 420. After the first camera group 130 is supported and assembled by a bracket 440, a shooting direction is formed towards the partition board 430 and towards the upper surface of the first movement trajectory. The second camera group 140 is located in the lower cavity, forming an outward shooting direction and towards the inner side of the second movement trajectory.

[0045] Refer to the appendix Figure 1 As shown, it further includes an assembly rack 450 that extends from the transportation platform 400 into the upper cavity 410. A touch screen 460 for displaying the acquisition results of the first camera and the second camera is provided on the assembly rack 450. At this time, the shooting results can be directly viewed through the touch screen, making it more convenient to use. Existing picture stitching technology can also be built in to display complete photos, providing convenience for direct screening, etc. When it is unqualified, it will be removed.

[0046] In actual assembly, the initial end of the conveying mechanism 100 is connected to a cigarette storage library for providing cigarettes, and the end of the conveying mechanism is connected to a rejection mechanism 500.

[0047] Refer to the appendix Figures 5-6As shown in the figure, the rejection mechanism 500 in this embodiment includes a push plate 510 and a driving mechanism for driving the push plate. The driving mechanism drives the push plate to form an arc-shaped reciprocating motion trajectory close to the cigarette. In this embodiment, the air valve 520 and the cylinder 530 are used to form the drive. Furthermore, the rejection action is to push the cigarette out by the air intake of the air valve 520 to push the push plate, and then immediately suck the push plate back by the air outlet.

[0048] In this embodiment, the lighting components are connected in series. The lamp bead housing is fixed to the detection housing by screws. The advantage of the arc-shaped setting of the detection housing is that the cigarette detection area is more comprehensive.

[0049] In this embodiment, two cameras are set in each camera group. These two cameras shoot the cigarette at a certain angle. If only one camera is used, it is indeed impossible to achieve 360° full coverage.

[0050] The first camera group is fixed on the table through a bracket and screws. The second camera group is fixed under the table above the transport table through a bracket and screws.

[0051] In actual production, refer to the appendix Figure 1-8 As shown in the figure, the cigarette appearance detection device for cigar cigarettes in this embodiment includes a frame assembly, a conveying mechanism located on the frame assembly, and 2 groups of camera groups located on the frame assembly and arranged along the frame assembly. Then, at the end of the conveying mechanism, a rejection mechanism for rejecting unqualified cigarettes is provided.

[0052] In this embodiment, the distance between the two camera groups is constant, and the movement speed of the conveying mechanism is constant. Furthermore, according to the picture information in the first camera group and the second camera group within the set time difference, the image information of different parts of the same cigarette can be obtained.

[0053] In this embodiment, the functions of various mechanisms are introduced as follows:

[0054] Electric control cabinet components: mainly composed of an industrial computer, an IO control board, two signal transfer boards, etc., mainly used for receiving and transmitting signals, processing images, etc.

[0055] Touch screen components: on the one hand, used to display real-time images, detection results, rejection rates, etc., and on the other hand, used to adjust various parameters, including camera parameters, control board parameters, detection software parameters, etc.

[0056] Detection box 2 components: composed of a set of LED strip light sources, a set of high-speed cameras, other mechanical accessories, etc., used to detect the appearance quality defects of half of the circumferential surface of cigar cigarette sticks.

[0057] The principle applied in this embodiment for detection is specifically as follows: The control board determines that the position where the cigarette to be photographed is in place based on the signal obtained by the trigger fiber optic, controls the LED light sources of the detection probes at two stations to light up, and simultaneously controls the camera to collect images. The camera transmits the collected images to the industrial control computer. The detection software processes the transmitted images through internal algorithms (the algorithms include: deep learning, grayscale detection, line detection, line association, etc.). After the processing is completed, the industrial control computer sends the processing results to the control board through the communication bus. The control board eliminates the defective cigarettes by means of moving and removing according to the processing results.

[0058] Four gigabit network cameras are adopted, with two cameras equipped on both the front and back sides of the cigarette, providing a more comprehensive shooting angle, and the deep learning algorithm is used to more accurately find defects.

[0059] In this embodiment, during detection, the two camera groups are two identical detection boxes. The two detection boxes respectively detect the front and back sides of the cigarette. The two cameras inside the detection box shoot the front and back sides of the cigarette from different angles through the dust-proof glass, and at the same time, three strip light sources are used to illuminate the front and back sides of the cigarette comprehensively. Such a layout makes the detection area more comprehensive.
