Technical Field

[0001] This utility model relates to the field of UV coating technology, specifically to an automated UV texture coating device and a coated panel. Background Technology

[0002] Currently, traditional processes for surface texturing decoration on glass, metal, and other sheet materials mainly rely on two methods. One is using double-sided adhesive for bonding. While simple, this method suffers from limited bonding strength, poor durability, and the inability to achieve complex three-dimensional textures. The second method is using sheet-to-sheet UV curing bonding. Although this method achieves better bonding and texture transfer, it is limited by a single-sheet operation mode, resulting in low production efficiency. It is difficult to achieve continuous, automated decorative production of large-size or extra-long sheets, and material waste is high.

[0003] With the increasing demand for personalized and diversified large-area decorative components in the home appliance and building materials industries, there is a need for a UV texture coating solution for large-size panels that can balance high efficiency and flexibility and enable continuous automated production.
