Brightening optical grating mold is carved grating fringe by diamond cutter conventionally on running roller, but diamond cutter can only process on non-ferrous metal, and the machining property of non-ferrous metal is poor, and service life is short, can not meet the demand of current large scale industrialization in enormous quantities.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of brightening optical grating mold of being convenient to processing, long service life.
The present invention also will provide a kind of preparation method of above-mentioned brightening optical grating mold.
The technical scheme that technical solution problem of the present invention adopts is: brightening optical grating mold, comprise full base roller, and on described full base roller, be disposed with copper layer, nickel-phosphor alloy coating and grating.
Further, the diameter of described full base roller is more than 300mm, and length is more than 1800mm.
Further, the thickness of described nickel-phosphor alloy coating is more than 0.5mm.
Further, the pitch of described grating is less than 0.05mm.
The preparation method of brightening optical grating mold, the method comprises the following steps: 1) on full base roller, plate fine copper; 2) electroplate liquid of electroforming high content of phosphorus, the nickel-phosphor alloy coating of the high thickness of deposition high phosphorus, the composition content of this electroplate liquid is: nickelous sulfate 120-300g/L, nickel chloride 30-45g/L, inferior sodium phosphate 45-90g/L, boric acid 20-35g/L and sodium fluoride 30-50g/L; 3) on nickel-phosphor alloy coating, process grating, thereby make brightening optical grating mold of the present invention.
Further, step 2) described electroforming adopts the pulse power.
Further, step 2) phosphorus content >=12% (percentage by weight, as follows) of described electroplate liquid.
Further, step 2) thickness of described nickel-phosphor alloy coating is more than 0.5mm.
The invention has the beneficial effects as follows: the present invention adopts the electroplate liquid of the pulse power, electroforming process and high content of phosphorus, electroforming nickel deposited-phosphorus alloy on various metals intactly, phosphorus content can be up to 10-13%, what form is noncrystal nickel-phosphor alloy, more than thickness can reach 0.5mm, improve the microfabrication mechanical performance of diamond forming cutter to nickel-phosphor alloy, can obtain high fineness, precision die that can be machining large-sized easily, and the service life of greatly improving mould.The nickel-phosphor alloy that electroforming deposition process obtains, coating is even, and strong adhesion obtains the noncrystal of high content of phosphorus, can realize in theory zero wearing and tearing of mould roller.Particularly on grating mould roller, adopt nickel-phosphor alloy roller, can make its life-span increase 3-10 doubly, by Ultra-precision diamond grating mold Special Purpose Machine for Processing, processing fine structure grating lens.
The specific embodiment
First the present invention extrudes and scribes the full base roller of electroforming on figure roller at photoelectric display device, more than diameter is preferably in 300mm, more than length is preferably in 1800mm; Then adopt pulse power electroforming deposited amorphous state nickel-phosphor alloy, then adopt natural diamond machine tooling to go out high-accuracy grating mould roller, raster pitch is less than 0.05mm.Adopt that this ultraprecise grating mould roller can production precision reaches that 1 inch of 500 line is above, the grating lens of 90 ℃ of pitch 24-150 μ m, angle 88-100 °, heat resistance >, can process various lenticular optical textures simultaneously.
Method of the present invention comprises the following steps:
1) on full base roller, plate fine copper;
2) electroplate liquid of electroforming high content of phosphorus, the nickel-phosphor alloy coating of the high thickness of deposition high phosphorus, the composition content of this electroplate liquid is: nickelous sulfate 120-300g/L, nickel chloride 30-45g/L, inferior sodium phosphate 45-90g/L, boric acid 20-35g/L and sodium fluoride 30-50g/L;
3) on nickel-phosphor alloy coating, process grating, thereby make brightening optical grating mold of the present invention.
Above-mentioned steps 1) object is: because the electric conductivity of copper is high, can accelerate the speed of nickel-phosphor alloy electroforming deposition.Above-mentioned steps 2) electroforming deposition adopts the pulse power, the electroplate liquid of electroforming high content of phosphorus (phosphorus content >=12%), complete the accumulation of amorphous nickel-phosphor alloy coating, the thickness of amorphous nickel-phosphor alloy coating that deposition forms can reach 1mm, the thickness of coating forming can meet the depth of groove requirement of grating lens structure processing, and the thickness of general electrochemical process nickel-phosphor alloy can only reach 0.20-0.30mm, can not meet the needs of ultraprecise processing.Because the phosphorus content in coating is up to more than 7.5%, more than can making like this surface roughness arrival Ra0.008mm of diamond cutter processing, then by extruding or UV Stereolithography technique, can make high permeability, large-sized grating lens, also improve significantly the service life of ultraprecise mould simultaneously.
