A device and method for quality inspection of cigarette boxes based on image vision
By designing a rotating frame and clamping plate structure, the cigarette box is flipped on a conveyor belt, and an image vision inspection mechanism is used to inspect multiple sides of the cigarette box. This solves the problem that the flipping mechanism needs to be set up separately in the existing technology, and improves the accuracy and applicability of the inspection data.

AI Technical Summary
Technical Problem
In the existing technology, the cigarette box needs two flipping mechanisms set on two separate conveyor belts during the flipping process, which results in a limited range of applications and inaccurate detection data.
Method used
A cigarette box quality inspection device based on image vision is adopted. Through the design of rotating frame and clamping plate, the cigarette box is flipped on a conveyor belt, and multiple surfaces of the cigarette box are inspected by image vision inspection mechanism.
Benefits of technology
This technology enables cigarette boxes to be flipped over on a conveyor belt, improving the accuracy and applicability of the detection data and allowing different positions of the cigarette box to be effectively detected.

Abstract
This invention relates to the field of detection technology and discloses a cigarette box quality inspection device and method based on image vision. It solves the problem that the bottom of the cigarette box, in contact with the moving mechanism, can obstruct certain areas of the box, preventing effective inspection of those areas. The device includes a detection frame with a moving mechanism for driving the cigarette box. A rotating frame is located above the frame, with two side plates fixedly mounted on it. Clamping plates are located on the adjacent sides of the two side plates. A rotating shaft is located above the frame, and a rotating sleeve is fitted around it. The rotating frame and the rotating sleeve are fixedly connected. First support parts are rotatably fitted at both ends of the rotating sleeve. This device can inspect different locations on the cigarette box and allows for direct flipping of the cigarette box on a conveyor belt, expanding its applicability, ensuring effective inspection of the cigarette box, and improving the accuracy of the inspection data.
