Description

Technical Field

[0001] The utility model belongs to the technical field of printing equipment, in particular to a printed product detection device based on an area array camera. Background Art

[0002] Under high-speed printing, the printing quality needs to be monitored in real time. Since the paper is relatively soft, it will bend under its own weight when moving along the conveyor roller, causing the photographs to be distorted, affecting the shooting quality. Therefore, an electrostatic generator is designed to ensure the flatness of the paper. However, if the conveyor belt itself is relatively loose, it will affect the flatness of the paper.

[0003] After searching, a Chinese patent document (application publication number CN113075215A) describes a printed matter detection device based on an area array camera, which uses electrostatic adsorption to keep the paper in contact with the conveyor belt, ensuring the level of the paper during shooting and improving the image quality. However, if the conveyor belt itself is loose, it will affect the flatness of the paper. Utility Model Content
