Description

Packaging box printing and sorting equipment based on visual identification Technical Field The invention belongs to the technical field of visual detection, and particularly relates to a packaging box printing and sorting device based on visual identification. Background The core execution equipment for visual inspection of the cigarette case is an inspection machine, and the equipment is automatic detection equipment integrating an industrial camera, a high-definition lens, an industrial light source, an image processing system, a conveying mechanism and a waste rejecting mechanism and is specially adapted to the appearance inspection requirements of precision printing packaging boxes such as the cigarette case. The inspection machine takes a visual imaging technology as a core, high-speed and high-definition photographing is carried out on a cigarette case in the conveying process through an industrial camera, the acquired image is transmitted to an image processing system, pixel comparison and feature analysis are carried out on the acquired image and a preset standard cigarette case image, various printing and technological flaws on the surface of the cigarette case are automatically identified by utilizing a preset flaw judgment threshold value, unqualified products are automatically removed through a reject mechanism, automatic and standardized operation of cigarette case detection is realized, detection efficiency and detection precision are greatly improved, manual intervention is reduced, manual detection cost is reduced, and the rhythm of large-scale production of the cigarette case is adapted, so that the inspection machine becomes an indispensable key detection device on a cigarette case production line at present. The operation flow of the visual inspection of the cigarette case can be summarized into the following key steps that firstly, the printed semi-finished cigarette case or finished cigarette case is placed on the feeding part of the inspection machine in an aligned mode, the cigarette case is conveyed to an inspection area singly and orderly through the conveying function of the feeding mechanism, secondly, an industrial light source in the inspection area provides uniform and non-interference illumination, the imaging quality is prevented from being influenced by reflection generated by a special process on the surface of the cigarette case, an industrial camera synchronously photographs the conveyed cigarette case at a high speed, complete images of the front side, the back side and the edges of the cigarette case are collected, and finally, if the unqualified cigarette case is detected, the unqualified cigarette case is conveyed to a reject area by the conveying mechanism and is automatically rejected by the reject mechanism, and the qualified cigarette case continues to pass through a conveying channel to enter the procedures of subsequent sticking, packaging and the like, so that the whole visual inspection flow is completed. However, the cigarette case mostly adopts insulating materials such as high gram weight white cards, gold-silver cards, laser cards and the like, and the materials are extremely easy to generate static electricity due to the actions of high-speed friction, stripping and the like in the preceding procedures such as printing, film coating, die cutting and the like, and the static electricity is difficult to naturally dissipate and can continuously accumulate on the surface of the cigarette case. When the cigarette case with static electricity enters the feeding part of the inspection machine for conveying, the adjacent cigarette cases are mutually adsorbed and attached by the adsorption action of the static electricity, so that a material stacking phenomenon is formed, part of the material stacking is completely aligned and overlapped, and part of the material stacking is obliquely staggered and overlapped. For the cigarette case with stacked materials, the industrial camera of the quality control machine can only shoot the surface image of the uppermost cigarette case, the cigarette case positioned below is completely shielded, the image can not be acquired by the camera, further, any visual detection can not be carried out, and the cigarette case which is not detected below is misjudged as a qualified product and directly flows into the subsequent procedures. Disclosure of Invention In order to overcome the defects of the prior art and solve the technical problems, the invention provides a packaging box printing and sorting device based on visual identification, which can effectively remove stacked packaging boxes from a detection conveying process by arranging a quality control machine and prevent the stacked packaging boxes from entering a detection part, wherein the specific structure is as follows; The packaging box printing and sorting equipment based on visual identification comprises a quality inspection machine, wherein the quality inspection machine
