Device for patterning an optical element
First Claim
1. A device for patterning an optical element, comprising:
- a working platform, on which said optical element is carried, moving said optical element toward a first direction and a second direction;
a linear cutting pedestal mounted above said working platform, and having an upper sliding track at a top of said linear cutting pedestal and a lower sliding track at a bottom thereof;
a cutting tool positioned in said lower sliding track for moving back and forth in said lower sliding track, said cutting tool being adjusted to an appropriate position according to a predetermined pattern, and a first press force being provided by said cutting tool;
a weight sliding block, moving back and forth in said upper sliding track, and providing a second press force to said cutting tool; and
a shaft, positioned above said linear cutting pedestal, driving said linear cutting pedestal to move in a third direction, and said third direction being perpendicular to said first direction and said second direction;
wherein the cutting tool is used to pattern said optical element by means of a linear relative motion between said working platform and said cutting tool, and said predetermined pattern is uniformly formed on the optical element by said first press force of said cutting tool and said second press force of said weight sliding block.

Abstract
A device for patterning an optical element includes a working platform, a linear cutting pedestal, at least a cutting tool, at least a weight sliding block and a shaft. An optical element to be patterned is carried on the working platform. The working platform is driven to move horizontally. The linear cutting pedestal is mounted above the working platform. An upper sliding track in which the weight sliding blocks can move back and forth and provide appropriate press forces to the cutting tools, is disposed at the top of the linear cutting pedestal. A lower sliding track in which the cutting tools can move back and forth and be adjusted to appropriate positions according to patterns desired for the optical element, is disposed at the bottom of the linear cutting pedestal. The shaft is positioned above the linear cutting pedestal and drives the linear cutting pedestal to move vertically. By means of a linear relative motion of the working platform to the linear cutting pedestal, the cutting tools at the bottom of the linear cutting pedestal cut out grooves on the optical element.
