First, nano-imprint glue material is coated on a substrate to form an imprint glue layer. Then, a template is pressed into the imprint glue layer. After the imprint glue layer is cured and shaped, ultrasonic waves are emitted to the template by using an ultrasonic wave emission device on the upper part of the template to assist the separation of the template and the formed glue layer, the template is removed, and the demolding process is completed. Compared with the prior art, the patent solves the problems of serious deformation, tearing and excessive demolding force of the formed nano-imprint structure in the demolding process of the nano-imprint technology due to the cohesive force of the template and the glue layer, makes the pattern after imprinting completely consistent with photolithography, effectively reduces the demolding force, greatly improves the success rate of demolding, and makes large-scale industrial production possible.

[0003] In the deep processing of glass surfaces, in order to achieve a relief texture, mainly through silk screen printing and surface texture lamination, there is a simple color presentation effect, and a deeper relief visual effect cannot be superimposed due to the mismatch of properties. As is known to all, the ink layer coverage of some products is poor when silk screen printing is performed while maintaining the original pattern shape, so that multi-color printing needs to be performed in a complex and tedious manner. This increases the product scrap rate and increases the cost accordingly. SUMMARY
