Method for characterizing cigarette combustion carbon line quality by simulating whole cigarette smoking process of human body and full-vision measurement based on manipulator

Abstract

The invention relates to a method for characterizing cigarette combustion carbon line quality by simulating a human body cigarette smoking whole process and full vision measurement based on a manipulator. The method is as follows: a cigarette to be detected is clamped by the manipulator, and the axial direction of a cigarette placed at a clamping position is vertical to a camera of a camera systemand a light source of a lighting system; after the cigarette to be detected is ignited, the manipulator starts to move or statically burn according to a cigarette smoking path of a simulated human body, and the camera system collects an image of the cigarette before combustion and collects an image of a cigarette combustion ash column in real time; and when the cigarette is burnt to a set test length, the acquisition of the cigarette burning ash column image is stopped, an acquired image is processed, and the cigarette burning carbon line quality is judged according to obtained cigarette burning carbon line width and cigarette burning carbon line uniformity. According to the invention, through the real-time acquisition and datamation of cigarette combustion images, a test sample is accurately and objectively judged and compared, and the influence of test data distortion caused by single-side acquisition on the accuracy of a test result is avoided.

Description

technical field [0001] The invention belongs to the technical field of cigarette detection, and in particular relates to a method for simulating the whole process of human cigarette smoking based on a manipulator and measuring and characterizing the quality of cigarette burning carbon lines with full vision. Background technique [0002] Cigarette burning charcoal line, also known as charring line, refers to a black charcoal line between the bottom of the cigarette burning cone and the unburned section. During formation, suction and smoldering, the char line moves backwards with the combustion section. When a cigarette is smoked, most of the airflow enters from around the bottom of the combustion cone. During the smoldering process, the sidestream smoke escapes around the charcoal line at the bottom of the combustion cone. It can be seen that the width and structure of the charcoal line affect the cigarette. Important area for combustion air flow in and out. In addition, t...

AI Technical Summary

Problems solved by technology

At present, the industry mainly uses the visual method of technicians to compare and evaluate the burning uniformity of the charcoal line, the width and quality of the charcoal line of cigarettes, which is easily affected by the technical level, experience and subjective consciousness of the observers, thus affecting the evaluation results accuracy and objectivity

Moreover, the real-time data of cigarette burning cannot be collected and digitized through the visual method, which affects the use of data for scientific statistics and research

In addition, during the burning process of cigarettes, the charcoal line presents a closed ring structure. If only one-sided image acquisition is performed, it is impossible to conduct a comprehensive detection and evaluation of the test sample.

Therefore, in order to obtain accurate and objective test results, it is necessary to collect the combustion charcoal line of the test sample in a comprehensive and real-time manner, but there is no good solution in the industry technology at present.
