Abstract
The invention provides a micro lens mould roller with a simple technical skill. The micro lens mould roller comprises a mould roller; a UV (Ultraviolet) curable adhesive film layer and a microsphere surface layer are orderly arranged on the surface of the mould roller. The invention also relates to a manufacturing method of the micro lens mould roller and the method comprises the following steps of: (1) uniformly coating a UV curable adhesive on the surface of the mould roller and then carrying out primary photocuring to form the UV curable adhesive film layer; (2) in a coating device of the mould roller, coating glass microspheres on the semi-cured UV curable adhesive film layer; (3) then coating the UV curable adhesive again and carrying out secondary photocuring to immobilize the glass microspheres into the film layer of the UV curable adhesive, and finally forming the microsphere surface layer on which the spherical surfaces of the microspheres protrude out of the surface of the film layer; and (4) preparing the micro lens mould roller provided by the invention after the glass microspheres are completely cured,. By utilizing the method provided by the invention for production, multiple roller moulds can be simultaneously reproduced so that the production cost is greatly reduced; and the method provided by the invention also has the advantages of simple technical skill and shorter time for processing.
Description
Technical field
The present invention relates to a kind of method for making of mould, particularly relate to a kind of method for making of micro lens mould roller.
Background technology
Optical microlens is a kind of array being comprised of function element, has traditional functions such as focal imaging.In the plane distributing at optical microlens, can obtain one and be reflected or plane that diffraction forms by a series of lenticules, can obtain one group of relatively all even regular focus distribution.
Lenticule all copies production by mould or mould roller, and the manufacture method of traditional mould or mould roller has three kinds, and the first is to adopt ultra-precision machine tool to carry out micro-processing, because the measure of precision of structure is high, the process-cycle is long.The second is to produce by lithographic technique, and the third is to produce by electrochemical treatment, but the equipment investment of these two kinds of production methods is high, technology is complicated, is difficult to realize large-scale production.
Summary of the invention
Technical matters to be solved by this invention is to provide the simple method for making of making described micro lens mould roller of a kind of technological process.
The technical scheme that technical solution problem of the present invention adopts is: described micro lens mould roller, comprise mould roller, on described mould roller surface, be disposed with UV light binding rete and microsphere top layer, described method for making comprises the following steps: 1), at the surface uniform coating UV light binding of mould roller, form UV light binding rete after a photocuring; 2) in mould roller coat cloth apparatus, coated glass microballon on the UV of described photocuring light binding rete; 3) coating UV light binding carries out secondary light and solidifies again, and glass microballoon is fixed in the rete of UV light binding, and the sphere that finally forms glass microballoon is protruding in the microsphere top layer of film surface; 4) after glass microballoon solidifies completely, just completed the once manufacturing process of described micro lens mould roller.
The invention has the beneficial effects as follows: adopt method of the present invention to produce, can copy many roller moulds, production cost significantly reduces simultaneously, and technology is simple, and process time is shorter.

Embodiment
The present invention is a kind of method that the UV of utilization light binding is made lenticule mould, first on running roller, coat UV light binding, UV light binding can bought on the market, by primary photocuring, at roller surface, form semi-solid preparation rete, then even coated glass microballon in the UV of semi-solid preparation light binding coating, glass microballoon should select to meet the particle diameter of lenticule optical design requirement.Through secondary light, solidify and make glass microballoon form a kind of half floating layer state and be solidificated in the UV light binding of mould roller again, it comprises following concrete steps:
1) the mould roller after cleaning is placed in to absolute ethyl alcohol degreasing;
2) at the surface uniform coating UV light binding of mould roller, after a photocuring, form the UV light binding rete 1 of semi-solid preparation, temperature is preferably controlled at 20 ℃-25 ℃, as shown in Figure 1;
3) in mould roller coat cloth apparatus, coated glass microballon on the UV of above-mentioned semi-solid preparation light binding rete 1, speed is preferably per minute 20-30 and turns, and temperature is preferably controlled at 20 ℃-25 ℃, as shown in Figure 2;
4) coating UV light binding carries out secondary light and solidifies again, glass microballoon is fixed in the rete of UV light binding, temperature is preferably controlled at 50 ℃-60 ℃, light application time is preferably 10s-15s, light application time is long can affect quality and production capacity, the too short meeting of light application time causes products solidifying bad, and the sphere that finally forms glass microballoon is protruding in the microsphere top layer 2 of film surface, as shown in Figure 3;
5) after glass microballoon solidifies completely, just make micro lens mould roller of the present invention, then this mould roller is installed on the solid machine of UV light, just can realize batch production lenticule 4, as shown in Figure 4.
