Following detailed description of the invention further illustrates the present invention in connection with above-mentioned accompanying drawing.
Detailed description of the invention
As shown in Figure 1, the impression roller 10 of the embodiment of the present invention is used for impressing optical thin film (for example, increment film, reflectance coating etc.) to form micro-structural on optical thin film, and impression roller 10 comprises that one is originally taken turns 11 and be arranged on original shaping membrane 12 of taking turns on 11.
Originally for example take turns 11, for the cylindrical structural of metal material (, copper), it has an excircle 110, and shaping membrane 12 arranges around whole excircle 110, and shaping membrane 12 is seamless design.
As required, the length of shaping membrane 12 can equal original 11 the length of taking turns, and also can be less than original 11 the length of taking turns.
Shaping membrane 12 has a forming surface 120 that deviates from excircle 110, in forming surface 120, have the micro-structural of micro-structural imprinted pattern 121 to be used on moulding optical thin film, micro-structural imprinted pattern 121 can be that projective structure, sunk structure or projective structure and sunk structure all have.Shaping membrane 12 is made up of macromolecular material that can immunity, for example, and dimethyl silicone polymer (Polydimethylsiloxane, PDMS).Dimethyl silicone polymer has good surperficial resistance to bond and pliability, and the optical thin film that shaping membrane 12 and impression roller 10 are manufactured is easily separated from each other, thereby does not affect the product yield of this optical thin film.
Above-mentioned impression roller 10 can preparation method as shown in Figure 2 obtain, and preparation method specifically describes as follows:
Step 1, makes master mold.Master mold 20 is slab construction, can be obtained by any one processing matrix 21 in following three kinds of methods, and matrix 21 has a machined surface 22, and the material of matrix 21 can be copper.
Preferably, the width of matrix 21 at least equals original 11 the circumference of taking turns, and the length of matrix 21 at least equals the length of shaping membrane 12.
One, utilizes laser aid processing matrix 21 to obtain master mold 20.Laser aid 30 comprises laser instrument 31, speculum 32 and collector lens 33, the laser parallel machined surface 22 that laser instrument 31 sends, laser is reflected onto on collector lens 33 after inciding on speculum 32, collector lens 33 converges to laser on the machined surface 22 of matrix 21, along with laser aid 30, relative to continuous movement of matrix 21, (or laser aid 30 is motionless, matrix 21 moves), laser just can be processed to form pattern transferring 23 on machined surface 22, thereby obtains master mold 20.
Certainly, laser aid 30 also can omit speculum 32 and collector lens 33, and the laser vertical that allows laser instrument 31 send is radiated on the machined surface 22 of matrix 21, so not only can simplify the structure of laser aid 30, and all energy of laser can be concentrated on matrix 21 and not loss too much.
Its two, CNC(Computerized Numerical Control, computer numerical control (CNC)) ultraprecise processing matrix 21 to be to obtain master mold 20.Adopt diamond cutter 40 to process pattern transferring 23 on the machined surface 22 of matrix 21, thereby obtain master mold 20.
Its three, sand blasting unit process matrix 21 obtain master mold 20.Adopt sand blasting unit 50 on machined surface 22, to carry out blasting treatment to form pattern transferring 23, thereby obtain master mold 20.In sandblast process, destroyed in order to prevent from not needing forming the part of pattern transferring 23, one veil (mask) can be placed between sand blasting unit 50 and matrix 21, need to form the part of pattern transferring 23 and cover the part that does not need to form pattern transferring 23 to expose to the open air.
Step 2, utilizes master mold to make metal plate mould.Utilize electroforming mode electroforming metal on the whole machined surface 22 of master mold 20, so, on pattern transferring 23, filled up by electroforming metal equally, then etch away master mold 20, thereby form the structure metal plate mould 60 contrary with master mold 20, the inverted configuration of the pattern transferring 23 on structure and the matrix 21 of the imprinted pattern 61 on metal plate mould 60.
Step 3, allotment PDMS solution.The PDMS host (Base) of certain proportion (for example 10:1-15:1) and curing agent (Curing agent) are placed in a container 70, then be uniformly mixed, PDMS host is hardened, to make PDMS solution, thereby obtain the membrane material to be formed 71 of macromolecule network.In whipping process, if produce bubble, need through vacuum defoamation processing.
In the present embodiment, the mass ratio of PDMS host and curing agent is 10:1, and container 70 can be measuring cup.
Part need to be described, make master mold and allocate PDMS solution there is no strict sequence limit, can first allocate PDMS solution, then make master mold.
Step 4, adopts spray equipment 80 that membrane material 71 to be formed is sprayed on to original wheel on 11 excircle 110, thereby forms film 81 to be formed.Owing to adopting spraying method, film 81 to be formed is whole as a whole, without dividing of beginning and ending, therefore film 81 to be formed is jointless structure.Along with original take turns 11 continuous rotation and spray equipment 80 along original take turns 11 axially constantly mobile, membrane material 71 to be formed is uniformly coated on excircle 110, thereby forms the film to be formed 81 of even thickness.
By controlling quantity for spray, spray time and the spraying rate of spray equipment 80, can control the thickness of film 81 to be formed.
Step 5, originally take turns 11 and be placed on metal plate mould 60 what there is film 81 to be formed, and make originally to take turns 11 and on metal plate mould 60, rotate one week, imprinted pattern 61 on metal plate mould 60 just can be transferred on original film to be formed 81 of taking turns on 11, to form micro-structural imprinted pattern 121 on film 81 to be formed, the structure of micro-structural imprinted pattern 121 is identical with the structure of pattern transferring 23 on the contrary mutually with imprinted pattern 61, and baking-curing film 81 to be formed can obtain shaping membrane 12 and original impression roller 10 of taking turns 11 compositions.
Take turns 11 and be placed in the baking box of 25-100 degree original, baking-curing film 81 to be formed and micro-structural imprinted pattern 121.
The manufacture method of impression roller forms dimethyl silicone polymer film with spraying process original wheel on 11, then utilize the metal plate mould 60 of plane imprinted pattern 61 to be transferred on the dimethyl silicone polymer film of curved surface to form shaping membrane 12, and metal plate mould 60 can repeatedly utilize a large amount of production impression rollers 10, reduces the process time of impression roller 10 and provides cost savings.
Be understandable that, those skilled in the art also can do other variation etc. and be used in design of the present invention in spirit of the present invention, as long as it does not depart from technique effect of the present invention and all can.The variation that these do according to spirit of the present invention, within all should being included in the present invention's scope required for protection.
