Production method, workpiece and production device of three-dimensional pattern

Abstract

A production method of three-dimensional pattern is disclosed. First, an adhesive layer is applied on a three-dimensional workpiece. Next, a film is vacuum adsorbed on the adhesive layer so that the film is impressed onto the adhesive layer to form the three-dimensional pattern on the adhesive layer. Finally, the adhesive layer is cured by implementing a plurality of heat treatments thereon. A workpiece of three-dimensional pattern and a production device of three-dimensional pattern are also disclosed.

What is claimed is:  
     
         1 . A production device of three-dimensional pattern adapted to form a three-dimensional pattern on a surface of a workpiece, the production device comprising:
 a lower mold, on which the workpiece is adapted to be mounted, having at least through hole;   a vacuum generator communicating with the through hole;   a upper mold disposed over the lower mold and adapted to expose a surface of the workpiece;   a film disposed on the upper mold and over the workpiece exposed by the upper mold, wherein the film has a three-dimensional pattern suitable for impressing an adhesive layer on the workpiece; and   a curing unit capable of applying light or heat on the adhesive to cure the adhesive layer.   
     
     
         2 . The production device of three-dimensional pattern as claimed in  claim 1 , wherein the lower mold has a lifting mechanism.
