Description

Technical Field

[0001] The present invention relates to the technical field of commodity cigarette analysis, and in particular to a cigarette analysis system and analysis method based on large model vision. Background Art

[0002] Commercial cigarettes are tobacco products that are cut into shreds, processed, and wrapped in special paper into long cylindrical strips. Cut tobacco is the core part of commercial cigarettes. It is made of tobacco leaves that have been dried, baked, etc. and cut into shreds. Different types of tobacco (such as flue-cured tobacco, air-dried tobacco, burley tobacco, etc.) can be mixed in a certain proportion to prepare tobacco with different flavors. The filter is located at one end of the commercial cigarette and mainly plays the role of filtering some harmful substances. Modern filters are usually made of materials such as acetate fiber. The design of the filter has many forms, such as ordinary single acetate fiber filters and composite filters with adsorbent materials such as activated carbon. Commercial cigarette paper is the paper that wraps the tobacco. It needs to have certain air permeability and combustion performance. The air permeability of commercial cigarette paper will affect the burning speed and taste of commercial cigarettes. If the air permeability is too strong, the burning speed of commercial cigarettes will be too fast, which may cause the taste to deteriorate. If the air permeability is too weak, it may cause incomplete combustion. The material of commercial cigarette paper is usually specially made, and some additives will be added during the production process to control its combustion performance and appearance.

[0003] In the prior art, during the production and processing of commercial cigarettes, commercial cigarettes in the processing batch are analyzed to monitor the quality of raw materials, silk making process and rolling process in the commercial cigarette processing process. The current manual analysis method requires the use of different measuring tools in sequence when measuring multiple indicators of cigarettes, which is difficult to meet the detection needs of fast production lines. With the increase of working hours and the accumulation of fatigue, the judgment criteria may change, thereby affecting the consistency of the test results. Summary of the invention

The image acquisition camera 610 on the three sides collects image information of the outside of the commodity cigarette sample and sends the collected image information data to the inside of the controller 3. During the image information collection process, the micro motors 417 on the left and right sides cooperate to drive the rotating rollers 418 at the corresponding positions to rotate synchronously in the same direction, so that the commodity cigarette samples on the inner sides of the two rotating rollers 418 rotate axially under the action of friction to cooperate with image collection;

[0075] Step 4: After the external image information is collected, the base frame 44 moves to the position below the cutting mechanism 7, the first electric telescopic rod 416 shortens and drives the first mounting plates 415 on both sides to move outwards, and the first mounting plates 415 on both sides drive the rotating rollers 418 on both sides to move outwards under the limiting action of the first guide rail assembly 414, so that the commodity cigarette sample falls on the top of the top plate 413, the second electric telescopic rod 71 drives the mounting frame 72 to descend to the specified height, and the fourth electric telescopic rod 79 drives the slot frame 77 to move downward on the outside of the slide rail rod 76, so that the blade 78 cuts off the filter tip and tobacco part of the commercial cigarette sample, the fifth electric telescopic rods 713 on both sides extend to drive the push block 712 to move downward, so that the push block 712 presses the tobacco part downward to assist in separating it from the cigarette holder part, the third electric telescopic rod 75 drives the second rotating frame 73 to rotate downward outside the mounting frame 72, the second rotating frame 73 drives the longitudinal cutting module 74 to fit the outside of the commercial cigarette sample, and the internal motor of the longitudinal cutting module 74 drives the saw blade to rotate to cut the outer commercial cigarette paper of the tobacco part longitudinally, thereby exposing the tobacco part to the outside;

[0079] Step 8: The image preprocessing module uploads the processed data to the model analysis module. The model analysis module detects whether the length and circumference of the cigarette meet the standards based on the image information. By defining the standard size range of cigarettes and the surface texture and appearance characteristics of normal cigarettes in the model, the collected cigarette images are measured and judged. When abnormal textures, spots, scratches, exposed tobacco or color changes appear, it is determined that there are defects, and the defects on the surface of the cigarette are identified. According to the color range and uniformity standards of different grades and types of tobacco learned by the model, the collected tobacco images are subjected to color quantitative analysis to determine whether they are within the normal range. For the uniformity of tobacco, the distribution density of tobacco in the collected tobacco images is analyzed to calculate the uniformity index. When the uniformity is lower than the set standard, the tobacco distribution is determined to be uneven.

[0080] Step 9: The model analysis module uploads the completed data to the output feedback module. The output feedback module displays the analysis results in an intuitive visual interface, generates a three-dimensional image to display the size measurement results and defect locations of the cigarettes, and generates a detailed analysis report based on the tobacco quality analysis data. The report includes various analysis indicators of the tobacco color and uniformity of the commercial cigarettes. The output feedback module sends the analysis results directly to the control system on the commercial cigarette production line. The control system adjusts the production parameters in a timely manner and removes problematic cigarettes to improve the overall quality of the commercial cigarettes.
