Description
Technical field
The utility model relates to optical element, specifically, relates to a kind of grating sheet of high precision.
Background technology
Grating is a kind of by in conjunction with digital drawing and traditional printing technology, makes human eye under need not the situation by any instrument, all the picture of two dimension originally can be placed directly at the moment, can experience to clear and definite the special film of three-dimensional stereo effect.This is the mankind continue black and white picture again after colour picture, really the another much progress that steps to three-dimensional world.
Traditional grating mainly contains slit grating and column mirror grating two classes.
Slit grating (being the line style grating) is comparatively ripe the earliest grating, and its image-forming principle is the principle of pin-hole imaging.The slit grating ratio is easier to make, but slit grating transmittance very low (only 20-30%) therefore needs illuminating lamp, and energy consumption is big, and neither environmental protection is not energy-conservation yet.
The image-forming principle of column mirror grating is a lens curve refraction catoptric imaging principle, and there are many lens pillars of closely arranging in its front usually, and its back side is the plane.
Common column mirror grating has film material column mirror grating (being the mold pressing grating), film material column mirror grating is by the principle of two main pressure roller roll extrusion the film material to be carried out the grating that thermoforming processing forms, belong to post forming, article two, one of main pressure roller is the mould roller that there is strip post mirror former on the surface, another is the elasticity pressure roller that the surface has certain elastic material, adopt the elasticity pressure roller can not be damaged to the mould roller easily, the convenient manufacturing and use, but the elasticity pressure roller can produce surface deformation inevitably in the process of press membrane 3 D grating, thereby influence film material column mirror grating lenticular shape in surface and smooth finish, flatness, make product thickness inhomogeneous, mouldability, focusing is very poor, the product of producing sometimes in addition pro and con all can not distinguish, therefore can only process some more coarse products, produce low line number, broad-brush grating, the stereogram made from this grating, the pattern fineness is lower, and stereoscopic sensation and sharpness are very poor.
In addition, Chinese utility model patent instructions CN2570812 has announced the compound column mirror grating of a kind of lamina membranacea, by film material column mirror grating by adhesive layer and clear sheet be bonded together the institute form.The performance of the compound column mirror grating of this lamina membranacea improves than film material column mirror grating, but still based on film material column mirror grating, exist and the similar shortcoming of film material column mirror grating inevitably, can only process some more coarse products, produce low line number, broad-brush grating.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of grating sheet of high precision, this high precision grating sheet is the high column mirror grating sheet material of precision, but one-shot forming, transparency height, good moldability, not yielding, sharpness is high, focusing is strong, be easier to carry out post-production.The technical scheme that adopts is as follows:
A kind of grating sheet of high precision, the front of grating sheet have many lens pillars of closely arranging, and the back side of grating sheet is the plane, it is characterized in that: the grid stroke number of described grating sheet is the 99.5-100.5 line.
The grid stroke number of preferred above-mentioned grating sheet is 100 lines.
The thickness of preferred above-mentioned grating sheet is the 0.25-1.2 millimeter.
The data of grating sheet are become with the grid stroke array by grating pitch, grating pitch is meant the width (being the width of lens pillar) of grating grid line, the grid stroke number is meant the number of the lens pillar that is comprised in the width range of per inch on the grating sheet, and its relational expression is: grid stroke number=1 inch/grating pitch.
The thickness of grating sheet is meant that the top of lens pillar is to the distance between the grating sheet back side.
The cross-sectional edge of above-mentioned lens pillar is a curve, as the curve of circular arc, elliptic arc or other shape.
In the preferred version, the cross-sectional edge of above-mentioned lens pillar has one section circular arc; The radius of preferred this circular arc is the 0.1264-0.6 millimeter.More preferably above-mentioned lens pillar is a cylindrical part, that is to say, the cross-sectional edge of lens pillar (lens pillar is except part that the front of grating sheet is connected) is a circular arc.
The material of above-mentioned grating sheet can be PET (polyethylene terephthalate), PP (polypropylene), PVC (Polyvinylchloride), PMMA (polymethacrylate) etc.
The manufacture method of above-mentioned grating sheet can comprise the steps: successively that (1) send into plastic grain in the machine barrel of extruder, in the machine barrel of extruder to plastic grain plastify, mixing, form plastic melt; (2) compression molding: compression molding carries out at the compression molding device, and the compression molding device comprises mould roller and felt wrapped roll, and wherein there is post mirror former on the surface of mould roller, and the smooth surface of felt wrapped roll is equipped with cooling body in mould roller and the felt wrapped roll; The plastic melt of extruding from extruder die head enters the gap between mould roller and the felt wrapped roll, and plastic melt is through mould roller and felt wrapped roll extruding and cooling and shaping, forms that positive lens pillar, the back side are arranged is the grating sheet on plane.The grating sheet that above-mentioned steps (2) obtains after side cut (cutting on the Width more in case of necessity), fixed length section, obtains specifying the single grating sheet of specification again.
Utilize above-mentioned column mirror grating sheet material, again in conjunction with digital drawing and traditional printing technology, make raster 3-D picture, can allow plane pattern pass through the special optical refraction effect of grating sheet, show lifelike stereoeffect in the plane, its principle is: make the take up an official post light of what difference of pattern inject people's left eye and right eye by specific direction, make image form an aberration, this aberration be with our human eye when observing a three-dimensional body, because two horizontally separated on two different positions, the aberration that exists between the viewed subject image is the same.Therefore, by this method, need be by any instrument, anyone can draw 3 D grating and be placed directly at the moment, can experience to clear and definite the marvellous enjoyment of three-dimensional stereograph.
The utility model can be raw material with the plastic grain, by extruder and compression molding device, makes through one-shot forming, this column mirror grating sheet material transparency height, good moldability, not yielding, sharpness is high, focusing is strong, be easier to carry out post-production.This column mirror grating sheet material adopts highdensity grating pitch design, fineness is high, usually view and admire distance and be 0.15-1 rice, therefore being highly suitable for all kinds of commodity external packings decorates, the ornamental part that also can be used for all kinds of articles for daily use, for example solid hang go through, greeting card class, bookmark, name card for business etc.High precision grating sheet of the present utility model cooperates with corresponding high-fineness printed patterns (master pattern that is used to design will reach more than the 350dpi usually), and the 3 D grating that makes is drawn clear fineness; Simultaneously, high precision grating sheet of the present utility model is suitable for making change figure very much, the detachable 10-15 layer that reaches of figure layer, and therefore to change level extremely many for the change figure that makes, and the action continuity is very clear to link up.
