Abstract
The utility model provides a brightening optical grating mold which is convenient to machine and has long service life. The brightening optical grating mold comprises a whole blank roller; and a copper layer, nickel-phosphorus alloy plating and an optical grating are sequentially arranged on the whole blank roller. The brightening optical grating mold can integrally electroform and deposit nickel-phosphorus alloy on multiple metals by adopting a pulse power source, an electroforming technology and a high phosphorus content electroplate liquid, wherein phosphorus content can be up to 10-13%, the formed nickel-phosphorus alloy is an amorphous body nickel-phosphorus alloy, the thickness of the nickel-phosphorus alloy can be more than 0.5mm, therefore, the mechanical property of micro-machining of a diamond forming cutter on the nickel-phosphorus alloy is increased, the skyscraping degree of finish can be obtained, accurate molds with large size can be conveniently machined, and the service life of the mold is greatly prolonged. The nickel-phosphorus alloy obtained by using an electroforming deposition method has uniform plating and strong adhesive force; high phosphorus content amorphous bodies are obtained; and zero abrasion of a mold roller can be realized in theory. Particularly, the service life of the brightening optical grating mold can be prolonged by 3-10 times as a nickel-phosphorus alloy roller is arranged on an optical grating mold roller.
Description
Technical field
The utility model relates to the grating mould in a kind of photoelectric display device.
Background technology
The blast grating material is the light pipe element in the display device; Usually form by the grizzly bar of circular arc, cylinder, triangle equal section shape, be widely used in MD projection TV set, LCD module backlight, bore hole 3D television set and volumetric packaging material etc. in modern times in the Display Technique.
Blast grating mould usually on running roller through diamond cutter engraving grating fringe, but diamond cutter can only process on non-ferrous metal, the machining property of non-ferrous metal is poor, service life is short, can not satisfy the demand of current large scale industrialization in enormous quantities.
The utility model content
The utility model technical problem to be solved provide a kind ofly be convenient to process, the blast grating mould of long service life.
The technical scheme that the utility model technical solution problem is adopted is: blast grating mould, comprise full base roller, and on said full base roller, be disposed with copper layer, nickel-phosphor alloy coating and grating.
Further, the diameter of said full base roller is more than 300mm, and length is more than 1800mm.
Further, the thickness of said nickel-phosphor alloy coating is more than 0.5mm.
Further, the pitch of said grating is less than 0.05mm.
The beneficial effect of the utility model is: the utility model adopts the electroplate liquid of the pulse power, electroforming process and high content of phosphorus; Electroforming nickel deposited-phosphorus alloy on multiple metal intactly; Phosphorus content can be up to 10-13%, formation be noncrystal nickel-phosphor alloy, thickness can reach more than the 0.5mm; Improved the microfabrication mechanical performance of diamond molding cutter to nickel-phosphor alloy; Can obtain high fineness, can machining large-sized easily precision die, and the service life of greatly improving mould.The nickel-phosphor alloy that the electroforming deposition process obtains, coating is even, and strong adhesion obtains the noncrystal of high content of phosphorus, can realize zero wearing and tearing of mould roller in theory.Particularly on grating mould roller, adopt the nickel-phosphor alloy roller, can make its life-span increase 3-10 doubly, through ultraprecise single-point diamond grating Mould Machining special purpose machine tool, processing fine structure grating lens.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, the blast grating mould of the utility model comprises full base roller 1, on said full base roller 1, is disposed with copper layer 2, nickel-phosphor alloy coating 3 and grating 4.
The utility model is at first extruded at photoelectric display device and is scribed the full base roller 1 of electroforming on the figure roller, and diameter is preferably in more than the 300mm, and length is preferably in more than the 1800mm; On full base roller 1, plate fine copper then, form copper layer 2, adopt pulse power electroforming deposited amorphous attitude nickel-phosphor alloy coating 3 again, adopt the natural diamond machine tooling to go out high-accuracy grating 4 again, the pitch of grating 4 is less than 0.05mm.Adopt that but this ultraprecise grating mould roller production precision reaches that 1 inch 500 line is above, the grating lens of pitch 24-150 μ m, angle 88-100 °, hear resistance＞90 ℃, can process various lenticular optical textures simultaneously.
The method of the utility model may further comprise the steps:
1) on full base roller, plates fine copper, form copper layer 2;
2) electroplate liquid of electroforming high content of phosphorus; The nickel-phosphor alloy coating 3 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 30-40g/L and sodium fluoride 30-50g/L;
3) on nickel-phosphor alloy coating 3, process grating 4, thereby process the blast grating mould of the utility model.
Above-mentioned steps 1) purpose 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%); Accomplish the accumulation of amorphous nickel-phosphor alloy coating, the thickness of amorphous nickel-phosphor alloy coating that deposition forms can reach 1mm, and the thickness of coating of formation can satisfy the depth of groove requirement of grating lens structure processing; And the thickness of general electrochemical process nickel-phosphor alloy can only reach 0.2-0.3mm, can not satisfy the needs of ultraprecise processing.Because the phosphorus content in the coating is up to more than 7.5%; The surface roughness of diamond cutter processing is arrived more than the Ra0.008mm; Then through extruding or UV photocuring moulding process; Can make high permeability, large-sized grating lens, the service life of also improving the ultraprecise mould significantly simultaneously.
