Description

Technical Field

[0001] The utility model relates to a flexible strip box appearance detection device. Background Art

[0002] The cigarette industry mainly relies on high-speed, high-reliability tobacco packaging machinery. While producing and packaging at high speed, product quality is strictly controlled. The appearance quality of cartons and transparent paper is a key point of defect detection.

[0003] In the inspection of carton packaging quality, most cigarette companies use machine vision inspection to achieve packaging quality inspection of carton appearance, while effectively reducing the labor intensity of workers' visual inspection; but most of the current carton machine vision inspection systems can only perform fixed inspection of the appearance quality of cartons of a single size; and for cartons of different sizes and specifications, such as hard-pack cigarette cartons, soft-pack cigarette cartons, and slim cigarette cartons, they cannot be effectively compatible.

[0004] Therefore, it is urgent to develop a strip box appearance detection device that is compatible with strip boxes with different size specifications. Summary of the invention

[0005] In order to solve the problem that the existing carton appearance detection device can only detect the appearance quality of carton of a single size in a fixed manner, but cannot detect the appearance packaging quality of cigarette carton of different sizes, the utility model provides a flexible carton appearance detection device.

[0006] The utility model discloses a flexible strip box appearance detection device, comprising a light source box, wherein the light source box has a plurality of cameras, a plurality of light sources and a first guide bar and a second guide bar which are parallel to each other. The light source box also has a first linear module, a second linear module, a third linear module and a fourth linear module. The second guide bar is fixed, the first linear module and the second linear module are mounted on the light source box and are connected to the first guide bar for adjusting the distance between the first guide bar and the second guide bar, the third linear module and the fourth linear module are mounted on the inner bottom surface of the light source box and are respectively located on the outside of the two guide bars, the camera on the outside of the first guide bar is mounted on the fourth linear module and the distance between the camera and the first guide bar is adjusted by the fourth linear module, the light source and part of the camera on the outside of the second guide bar are mounted on the third linear module and the distance between the camera and the light source and the second guide bar is adjusted by the third linear module.

[0007] In order to prevent the light sources and cameras on the third linear module and the fourth linear module from interfering with each other during operation and to improve work efficiency, the working areas on the two guide strips are divided into a first workstation and a second workstation along the traveling direction of the cigarette strips. The light source and camera on the third linear module are aimed at the first workstation, and the camera on the fourth linear module is aimed at the second workstation.

[0008] In order to facilitate precise adjustment of the distance, each linear module has a connected servo motor and a lead screw, and a mounting block is threaded on the lead screw. The lead screws of the first linear module and the second linear module are connected to the first guide bar through the mounting block; the lead screw of the third linear module is connected to the light source and the camera through the mounting block, and the lead screw of the fourth linear module is connected to the camera through the mounting block.

[0009] Beneficial effects: The utility model adds four linear modules to the traditional light source box, so that the originally fixed first guide bar is replaced by the first linear module and the second linear module, so that the position of the first guide bar can be adjusted; the light source originally fixed on the outside of the second guide bar and a part of the camera are replaced by the third linear module, and the camera originally fixed on the outside of the first guide bar is replaced by the fourth linear module, so that the distance between the camera and the light source relative to the guide bar can be adjusted; thereby being compatible with the inspection of the appearance packaging quality of cigarette cartons of different sizes; by setting up two workstations, the light sources and cameras on the third linear module and the fourth linear module do not interfere with each other when working, thereby improving work efficiency; and by providing each linear module with a connected servo motor and a lead screw, it is convenient to accurately adjust the distance.
