Description

Technical Field

[0001] The utility model relates to the technical field of cigarette label modeling devices, in particular to a 3D modeling image acquisition platform for cigarette labels. Background Art

[0002] The flatness and indentation depth of the small box trademark are the main indicators for the quality control of cigarette materials. If the indicators are not well controlled, it will affect the production efficiency and the packaging forming effect of the small box trademark. At present, there is no high-precision means for detecting the flatness of the small box trademark in the industry. The main detection devices for the flatness of the small box trademark are straight rulers, altimeters, digital display altimeters, etc. The measuring personnel measure the heights of multiple points on the stacked small box trademarks one by one to obtain the height differences of each point, so as to realize the flatness detection. Using this method will introduce manual errors and affect the accuracy of the measurement results to a certain extent. In addition, there is also laser non-contact measurement. Although it improves the measurement accuracy and avoids the errors caused by human factors and deformation due to contacting the small box trademark, the detection speed is slow. It takes about 5 minutes to collect hundreds of height data points, and the data volume is limited, and the representativeness of the measurement results is poor.

[0003] Secondly, there is no special detection device for the indentation depth of the small box trademark, but a thickness gauge is used for detection. The commonly used thickness gauges are mainly from the American companies TMI and THWING-ALBERT, which are mainly used to measure the thickness of sheet-like objects such as films, cigarette papers, tipping papers, tobacco leaves, etc. The two instruments have a high measurement accuracy of up to 0.001 mm and a fast speed, and belong to contact measurement. However, when measuring the indentation depth with a thickness gauge, only the height at a specific position of one indentation can be measured, and there will be deformation errors during the measurement, resulting in poor reliability of the measurement results.

[0004] The 3D reverse modeling technology is a high-precision and cutting-edge technology in the industry. Applying it to the research on the adaptability of tobacco industry accessories to the machine has important significance. If we want to use the 3D reverse modeling technology to construct the three-dimensional point cloud model of the small box trademark, combine the corresponding three-dimensional detection platform software, accurately and completely extract the flatness and indentation depth information, and realize the fast and non-destructive detection of the flatness and indentation depth of the small box trademark, greatly improving the efficiency and accuracy of quality determination, it is necessary to develop a boxed cigarette label flatness detection device with simple operation and accurate measurement results for 3D modeling of cigarette labels, and this device also needs to be equipped with a platform for image acquisition of cigarette labels.
