Description
Technical field
The present invention relates to a kind of lens fabrication process technical field for projection screen, Salar light-gathering, especially for the taper roller making Fresnel Lenses.
Background technology
Fresnel Lenses (fvesnellens) is with inventor's Fresnel legal person naming, be made up of some donuts, because application is different, light can be converged in the center of circle, also can converge the Fresnel Lenses into line (face), and focal length can be designed arbitrarily.
Generally speaking, rear projection screen is launched by the image in projector, the eyes of spectators are entered through display screen, commercially with large scale, high image quality and frivolous for its feature, so need in design to consider viewing angle brightness, increase picture contrast and solve the problems such as anamorphose, wherein, the main function of Fresnel Lenses is the ray-collecting at the Vernonia parishii Hook. F. angle of projector being launched, originally the light dispersed can be concentrated in the visual angle of spectators, to reach the object increasing brightness of image.
Because Fresnel Lenses is a kind of optical articles, be all adopt diamond cutter to carve by three special axle Fresnel Lenses mold machine tools usually, then produce product by processes such as UV photocuring, cast, mold pressing, injection mouldings.Processing diameter due to ultraprecise diamond machine tool is domestic at present can only accomplish 2m, only has Japanese Toshiba to accomplish 3.4m in the world.Superhuge large scale Fresnel Lenses is limited to basic industries weakness, cannot realize producing, also someone adopts the method for splicing, but piece has a strong impact on the optical property of lens, particularly in field of video displaying, its Fresnel Lenses pitch used reaches 25 μm, and splicing vestige can not be had completely to occur.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, the taper roller for making Fresnel Lenses that a kind of structure is simple and roll forming is effective is provided, the Fresnel Lenses obtained is overall structure, do not splice vestige, good in optical property, the diameter of Fresnel Lenses does not limit by lathe, meets the large scale demand of projection screen, Salar light-gathering.
Object of the present invention is achieved through the following technical solutions: for making the taper roller of Fresnel Lenses, it comprises the left fixed shaft be fixedly connected sequentially, roller body and right fixed shaft, the endless belt micro-structural that roller body is successively decreased from left to right successively by multiple diameter is laminated, roller body with the small end of taper roller for the center of circle, the axial length of taper roller is radius, roll extrusion on the transparent panel scribbling UV light binding, endless belt micro-structural on roller body extrudes the concentric circular type serration groove structure that the transparent panel scribbling UV light binding obtains Fresnel Lenses, endless belt micro-structural is the circular fin being arranged at roller body side, the molded line that the surperficial molded line of the roller body that the tangent plane crossing roller body axis intercepts and Fresnel Lenses are intercepted along the two-way plane extended to form in direction paralleled to the axis by its radius matches, described left fixed shaft and the end face outside of right fixed shaft are respectively arranged with locating hole.
Described endless belt micro-structural is all gyration machining of main shaft by ultraprecise cylinder lathe and workbench.
Described roller body is that non-ferrous metal is made.
The surface of described roller body is coated with one deck non-ferrous metal.
The present invention has the following advantages:
1, the endless belt micro-structural that roller body is successively decreased from left to right successively by multiple diameter is laminated, endless belt micro-structural is the circular fin being arranged at roller body side, the molded line that the surperficial molded line of the roller body that the tangent plane crossing roller body axis intercepts and Fresnel Lenses are intercepted along the two-way plane extended to form in direction paralleled to the axis by its radius matches, and its structure is simple.
2, by taper roller gained to Fresnel Lenses be overall structure, do not splice vestige, good in optical property, the diameter of Fresnel Lenses does not limit by lathe, meet the large scale demand of projection screen, Salar light-gathering, Fresnel Lenses can be produced in batch, shorten the Fresnel Lenses production cycle, considerably reduce production cost.
