Description

Technical Field

[0001] The utility model relates to the technical field of UV printing equipment, in particular to a UV flatbed printer capable of automatically positioning. Background Art

[0002] A UV printer is a digital printing device that uses ultraviolet curing technology. It uses ultraviolet light to cure ink or paint to print directly on various types of surfaces. These surfaces can include glass, metal, plastic, ceramic, wood and other materials. Therefore, UV printers are widely used in advertising, logos, decoration, industrial production and other fields.

[0003] When printing on a printing plate, current UV printers usually place the printing plate directly on the top of the flat plate and then complete the printing through automatic control. This printing method makes it impossible to quickly locate the position of the printing plate, resulting in printing position deviation. Moreover, if the printing plate is not limited, the shaking of the equipment will also cause the printing plate to shift, thereby affecting the printing effect. Utility Model Content
