Composite roller mold with replaceable surface structure and manufacturing process thereof

Abstract

The invention relates to the technical field of optical plate production, in particular to a composite roller mold with replaceable surface structure and a manufacturing process thereof. The compositeroller mold is used for embossing an optical plate. The composite roller mold comprises a roller body and a metal belt with an outer surface with embossing structure; a mounting groove is formed in the outer peripheral surface of the roller body in the axis direction of the roller body; the metal belt is wrapped around the outer peripheral surface of the roller body; and an upper pressing strip and a lower pressing strip are sequentially arranged in the mounting groove from outside to inside, and a head end and a tail end of the metal belt are located between the upper pressing strip and thelower pressing strip. According to the composite roller mold and the manufacturing process thereof, the metal belt and the roller body are combined, on one hand, the metal belt is in a plane shape atfirst , so that the difficulty of machining of the embossing structure on the metal belt is greatly reduced relative to that of machining of the embossing structure on the circumferential surface, andtherefore forming of the embossing structure is facilitated; and on the other hand, the optical plates with different structures and different functions can be produced only by replacing the metal belt wrapped around the roller body so that the development period of the optical plates can be greatly shortened and production cost of the optical plates can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of optical plate production, in particular to a composite roller mold with a replaceable surface structure and a manufacturing process thereof. Background technique [0002] Optical plate is a plate with an optical three-dimensional structure on the surface. Its optical three-dimensional structure needs to have high precision. At present, the production of optical plates mainly adopts rolling and injection molding. Due to the high cost and difficulty of injection molding, it is currently the main choice in the industry. Roll forming, and the difficulty of roll forming lies in how to make a corresponding embossing structure for pressing the optical three-dimensional structure on the circumferential surface of the roller body, although machining or 3D printing can be used on the circumferential surface of the roller body The embossing structure is made on the surface of the roller body, but the price paid by t...
