Digital Roller Mold Manufacturing System

摘要

A digital roller mold manufacturing system for manufacture of exterior characteristic structures on a roller mold depends on an illuminator for generation and projection of a light source on a Digital Mirror Device (DMD) chip in which micro-mirrors are rotated a controllable angle for defining the light source as an optical image and projecting the optical image on first micro-lenses at which digital light energy is transformed from the optical image and transmitted to first optical fibers, second optical fibers via couplers, and second micro-lenses. Furthermore, the second micro-lenses focus the digital light energy as light spots which are received by a photo-resist layer externally covered on the roller for development of patterns with exterior characteristic structures on the roller mold because a control unit regulates rotations of the roller and horizontal shifts of second micro-lenses.

主权项

1. A digital roller mold manufacturing system, comprising:
a projection module comprising an illuminator, a Digital Mirror Device (DMD) chip and an imaging lens wherein the illuminator is used to generate a light source projected on the DMD chip at which an optical image to be projected on the imaging lens is created; a transformation module comprising at least a first micro-lens and at least a first optical fiber wherein the first micro-lenses receive the optical image projected on the imaging lens for transformation from the optical image to digital light energy which is further transmitted to the first optical fibers; a focusing module comprising at least a second micro-lens and at least a second optical fiber wherein the second optical fibers receive the digital light energy from the first optical fibers and transmit the digital light energy to the second micro-lenses at which the digital light energy is focused as light spots; and a roller mold comprising a roller and a photo-resist layer at which the light spots are received for development of patterns.
