Description

Technical Field

[0001] The utility model specifically relates to the technical field of visual recognition and positioning, and particularly relates to a visual recognition and positioning device for engraving patterns on a printing roller. Background Art

[0002] A printing roller usually consists of a roller body, a printing pattern layer and a surface coating; the roller body is generally made of steel or other high-strength materials to ensure its stability during high-speed operation and under pressure; the printing pattern layer is a specific pattern formed on the surface of the roller through technologies such as engraving, etching or laser printing, and various complex patterns can be designed according to different requirements; the surface coating plays a role in protecting the printing pattern, improving wear resistance and corrosion resistance.

[0003] Currently, when engraving the patterns on traditional printing rollers, through full-automatic machining centers for processing, although the processing of the printing rollers can be achieved, during the processing, the path of the pattern cannot be effectively marked, so it cannot be timely determined whether the pattern meets the processing requirements during the engraving process, which may cause deviation and the printing roller cannot effectively meet the requirements of printing production.
