Description
Technical field
The present invention relates to a kind of roller, particularly relate to a kind of roller for producing light guide plate.
Background technology
Light guide plate is the optical material utilizing acrylic/PC sheet material to make, and in order to improve the performance of light guide plate, is typically going out
Bright finish can design microstructure, the most V-shaped prism structure, and light guide plate is in forming process, and molding roller just becomes pass
The link of key, due to the existence that V-type molding structure is most advanced and sophisticated, rolling die easily occurs formed light conductive plate microstructure when
Draw the situation of material.
Summary of the invention
For the deficiency in the presence of prior art, the invention provides a kind of when producing excellent optical performance light guide plate
Do not have the roller for producing light guide plate drawing material situation.
For achieving the above object, present invention employs following technical scheme: a kind of roller for producing light guide plate, including
Forming surface, described forming surface arranges micro structure, and described micro structure includes some grooves that be arranged in parallel, that cross section is curved,
Forming reverse V-shaped projection between adjacent arc groove, described convex top arranges platform structure, wherein, and described arc groove deep
Degree D is 0.05-0.12mm, and the width W of described arc groove is 0.18-0.42mm, and the radius R of described arc groove is 0.125-
0.250mm, the width L of described platform structure are 0.006-0.015mm.
As preferably, degree of depth D of described arc groove is 0.08mm, and the width W of described arc groove is 0.27mm, described
The radius R of arc groove is 0.1650mm, and the width L of described platform structure is 0.01mm.
As preferably, on described roller, the thickness of copper plate is 0.05-0.15mm, and micro structure is arranged on copper plate.
As preferably, the heat-conducting mode in described roller is the cold or water-cooled of oil.
As preferably, the cross section of described arc groove is circular arc.
Compared to prior art, there is advantages that this is excellent in molding for producing the roller of light guide plate
During optical property light guide plate, owing to devising platform structure, therefore do not have the situation drawing material.
Accompanying drawing explanation
Fig. 1 is for producing the roll structure figure of light guide plate in the present invention.
Fig. 2 be in the present invention on the roller produce light guide plate micro structure partial sectional view.
Detailed description of the invention
Embodiment: see Fig. 1 and Fig. 2, a kind of roller for producing light guide plate, including forming surface, described forming surface sets
Putting micro structure, described micro structure includes some grooves that be arranged in parallel, that cross section is curved, is formed and fall between adjacent arc groove
V-type is protruding, and described convex top arranges platform structure, and wherein, degree of depth D of described arc groove is 0.05-0.12mm, described arc
The width W of connected in star is 0.18-0.42mm, and the radius R of described arc groove is 0.125-0.250mm, described platform structure
Width L is 0.006-0.015mm.Light guide plate excellent optical performance prepared by micro structure in this numerical range.
Degree of depth D of described arc groove is 0.08mm, and the width W of described arc groove is 0.27mm, described arc groove
Radius R be 0.1650mm, the width L of described platform structure is 0.01mm.
On described roller, the thickness of copper plate is 0.05-0.15mm, and micro structure is arranged on copper plate, meets preparation micro structure
Requirement while, the heat conduction and heat radiation in roller will not be significantly affected.
Heat conduction (cooling) mode in described roller is the cold or water-cooled of oil, and pipeline may be designed as the shape of straight tube or U-tube
Formula, specifically refers to prior art.
The cross section of described arc groove is circular arc.
Roller, during molding excellent optical performance light guide plate, owing to devising platform structure, therefore does not haves and draws material
Situation.
Finally illustrating, above example is only in order to illustrate technical scheme and unrestricted, although with reference to relatively
The present invention has been described in detail by good embodiment, it will be understood by those within the art that, can be to the skill of the present invention
Art scheme is modified or equivalent, and without deviating from objective and the scope of technical solution of the present invention, it all should be contained at this
In the middle of the right of invention.
