Abstract
The invention relates to a conical roller for making a Fresnel lens. The conical roller comprises a left fixed shaft (1), a roller body (2) and a right fixed shaft (3) which are sequentially fixedly connected, wherein the roller body (2) is formed by overlapping a plurality of ring microstructures (4) diameters of which are sequentially reduced from left to right, the ring microstructures (4) are annular beads arranged on the side surface of the roller body (2), a molded line of the surface of the roller body, cut by a section passing through an axial line of the roller body (2) is matched with that obtained by cutting the Fresnel lens by a plane formed by directionally extending the radius of the Fresnel lens along a direction of the axial line; locating holes (5) are formed in the end faces of the outer sides of the left fixed shaft (1) and the right fixed shaft (3). The conical roller has the advantages of simple structure and good rolling and forming effect; the obtained Fresnel lens is of an integrated structure without a splicing trace, and is good in optical performance; the diameter of the Fresnel lens is not limited by a machine tool, and the demand on large size of a projection screen and solar condensing is met.
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 of making Fresnel Lenses.
Background technology
Fresnel Lenses (fvesnel lens) is with inventor's Fresnel legal person naming, formed by some donuts, due to application difference, can converge light in the center of circle, also the Fresnel Lenses into line (face) can be converged, and focal length can be designed arbitrarily.
Generally speaking, rear projection screen is that the image in projector is launched, enter spectators' eyes through display screen, on market, be take large scale, high image quality and frivolous as its feature, so need in design to consider brightness, the increase picture contrast of viewing angle 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 that projector is launched, originally the light of dispersing can be concentrated in spectators' visual angle, to reach the object that increases brightness of image.
Because Fresnel Lenses is a kind of optical articles, be all to adopt diamond cutter to carve by three special axle Fresnel Lenses mold machine tools conventionally, then produce product by processes such as UV photocuring, cast, mold pressing, injection mouldings.Can only accomplish 2m because the processing diameter of ultraprecise diamond lathe is at present domestic, only have in the world Japanese Toshiba can accomplish 3.4m.Superhuge large scale Fresnel Lenses is limited to basic industries weakness, cannot realize production, 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, the Fresnel Lenses pitch of its use reaches 25 μ m, can not have splicing vestige to occur completely.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, provide a kind of simple in structure and roll forming effective for making the taper roller of Fresnel Lenses, the Fresnel Lenses obtaining is overall structure, do not splice vestige, good in optical property, the diameter of Fresnel Lenses is not limited 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 being fixedly connected sequentially, roller body and right fixed shaft, stacked the forming of endless belt micro-structural that roller body is successively decreased from left to right successively by multiple diameters, roller body is take the small end of taper roller as the center of circle, the axial length of taper roller is radius, roll extrusion on the transparent panel that scribbles UV light binding, the transparent panel that the extruding of endless belt micro-structural on roller body scribbles UV light binding obtains the concentric circular type serration groove structure of Fresnel Lenses, endless belt micro-structural is the circular fin that is arranged at roller body side, crossing the surperficial molded line of the roller body that the tangent plane of roller body axis intercepts and the molded line that Fresnel Lenses is intercepted along the two-way plane extending to form of direction paralleling to the axis by its radius matches, on the outside end face of described left fixed shaft and right fixed shaft, be respectively arranged with locating hole.
Described endless belt micro-structural is all by the gyration machining of main shaft and the workbench of ultraprecise cylinder lathe.
Described roller body is that non-ferrous metal is made.
On the surface of described roller body, be coated with one deck non-ferrous metal.
The present invention has the following advantages:
1, stacked the forming of endless belt micro-structural that roller body is successively decreased from left to right successively by multiple diameters, endless belt micro-structural is the circular fin that is arranged at roller body side, cross the surperficial molded line of the roller body that the tangent plane of roller body axis intercepts and the molded line that Fresnel Lenses is intercepted along the two-way plane extending to form of direction paralleling to the axis by its radius and match, it is simple in structure.
2, by taper roller gained to Fresnel Lenses be overall structure, do not splice vestige, good in optical property, the diameter of Fresnel Lenses is not limited by lathe, meet the large scale demand of projection screen, Salar light-gathering, Fresnel Lenses can be produced in batch, shortened the Fresnel Lenses production cycle, significantly reduced production cost.
