Description
Technical field
The present invention relates to a kind of reflectorized material technical field, be specifically related to a kind of structure and job operation thereof of improving diamond reflecting film reflective taper.
Background technology
The regression reflecting material has the characteristic that incident light is returned by former road, and this specific character is different from direct reflection and diffuse reflection.This specific character of regression reflecting material makes it extensively apply to aspects such as various traffic alarms and personal security.The for example warning notice on the vehicle or the warning against danger sign on the road, traffic control sign and navigation marker, billboard or the like.
Present reflectorized material has two types: reflectorized material and the reflectorized material with microprism array structure with micro-sphere array structure.The reflectorized material of micro-sphere array structure is known as the reflectorized material of " microballon " array structure again, and its reflector layer is made up of a lot of little microballons, and these microballons evenly are arranged on the bonding coat closely, and the part of microballoon is embedded in the bonding coat.The microbead type reflectorized material has wide incident angle and viewing angle, but its light echo reflectivity is lower, the process relative complex of back side metallization film.Chinese patent CN2383080Y etc. has introduced the structure of microbead type reflectorized material.The reflectorized material of microprism array structure generally is made up of one deck thin hyaline layer (body layer) and the surperficial reflector layer that has the cube microprism.The cube microprism of these standards is made up of three faces, and these three faces are orthogonal in twos.Structure difference according to the cube microprism can be divided into rescinded angle microprism and complete microprism.Three faces of standard rescinded angle microprism are isosceles right triangles, and three faces of complete microprism are squares.The microprism reflectorized material owing to its preferably reflective function be widely used in every field.The structure and the method for making of microprism reflectorized material have been described at Chinese patent CN101738661A, CN1208375A.
The quality of general evaluation regression reflecting material behavior has four indexs: the wide-angle property of anisotropy (Orientation), incident light (Entrance angularity), the homogeneity of reflective taper and the processibility of structure.Can improve anisotropy through rotating reflective element; Can improve its wide-angle property through the reflective element of deflection; Can improve the homogeneity of reflective taper through the side of diffraction mode or the reflective element of deflection; Reduce difficulty of processing and time through rational design, thereby improve the processibility of structure.
First procedure of making the microprism reflectorized material is to make the master mold (formpiston) that the surface has little geometry, and the surface structure of master mold is exactly the geometry of the reflective element of final products.Utilize this master mold to make the molding tool (cavity block of mould just) that is used to produce then, utilize cavity block to come compacted products again through suitable technique (for example nickel galvanoplastics).The method of making master mold has three kinds: pin the tie in technology of tying up, substrate combination technique and whole process technology.
The pin technology of tying up that ties in is exactly to be bundled by the geometry that a lot of ends have a microprism and forms master mold.United States Patent (USP) U.S.Pat.NO.1591572 (Stimson) and U.S.Pat.NO.3926402 (Heenan) have introduced dependency structure and manufacture.The pin technology of tying up that ties in can be made a lot of different reflective elements in a master mold, because the reflective element of each in the master mold all is to make separately.It is unpractical that yet such technology is used to make small reflective element, because the reflective unit that need to make have very little of a lot of and size.
The substrate combination technique is combined by a lot of narrow substrates and is constituted master mold, is arranging little geometry on these narrow substrates.The substrate combination technique is with respect to tie in a lot of labours that tied up techniques save of pin because in the substrate combination technique seldom a part be independent manufacturing.For example on a narrow substrate 400-1000 independent elements are arranged generally, and have only an independent element on a pin bundle.Tie in pin and to tie up compared with techniques, the substrate combination technique has poor flexible design degree.U.S.Pat.NO.6015214 (Heenan et al.); U.S.Pat.NO.5981032 (Smith); U.S.Pat.NO.6057860 (Luttrell) has introduced the related example of substrate combination technique.
Whole process technology is exactly to cut on a flat workplace through a series of V-arrangement cuttves, forms the master mold that has the rescinded angle micro-prism structure.This several rows of reflective element is to be formed by the cutting of three types V-arrangement cutter, and these three kinds of V-arrangement cuttves are mutually 60 degree.The bottom surface of these reflective elements all is identical equilateral triangle (referring to U.S.Pat.NO.3712706 (Stamm)).But the angle between these three kinds of V-arrangement cuttves also can not be 60 degree, and the reflective element of formation is (referring to U.S.Pat.NO.4588258 (Hoopman)) that tilt.In whole process technology, the side of same row's element is formed the cutting of V-arrangement cutter by same.For this reason, whole process technology can produce the very little reflective element of size accurately, but has reduced the flexible design degree of element structure, has influenced the integral inverted light characteristic of reflectorized material.
In the utilization of reality, the angle pyramid reflectorized material of standard is infeasible.For example, the sign board that light is made by reflectorized material from the car light directive of automobile, by former road reflected back car light, because people's eyes and car light be in same position, so the people can't see sign to light by reflectorized material then.The light that only reflects gets into people's eyes, and sign could be in sight.Therefore, the light that reflects need be the light of a misconvergence of beams, just as the reflective taper of mentioning before this.In conventional retroreflective materials, the method that forms light cone has: (1), make the face out-of-flatness (being similar to diffuse reflection) of reflection element; (2), through the diffraction of light effect.With reference to U.S.Pat.No.3712706 (Stamm); (3), change the geometry of reflective element, make three dihedral angles of reflective element depart from orthogonality relation.
H.D.Eckhardt delivers paper " optical principle of cube microprism " that paper " naive model of cube reflector phenomenon " and N.E.Rityn about optics deliver in July, 1971 and has disclosed the principle that cube-corner prism scatter incident light forms diverging light.Describe like article, rotate the face of reflective element, the face that makes it is not orthogonal or quadrature.Be distributed to different directions (opposite direction along incident light is a central distribution) with regard to causing by the light that reflective element reflects like this.Thereby the light that obtains dispersing.
The structure that a lot of design effort change reflectorized materials improves the performance of reflectorized material, but its use that still a lot of drawbacks limit arranged.Enterprise hopes to find more advanced project organization and manufacturing approach to make reflectorized material, lets this reflectorized material have good reflective function and manufacturing efficient.
Summary of the invention
The present invention has overcome the deficiency of prior art, and a kind of structure and job operation thereof with improvement diamond reflecting film reflective taper of reflective function is provided.
Consider the problems referred to above of prior art, according to an aspect disclosed by the invention, the present invention adopts following technical scheme:
The present invention proposes a kind of new microprism reflectorized material structure, and this structure is to be formed by specific mode cutting by the V-arrangement cutter.In brief; This reflective structure is made up of a series of reflective elements (single reflecting unit); Three sides of reflective element are to form through three staggered V-arrangement cutter cuttings, and these three staggered V-arrangement cuttves are mutually 60 degree, and the cutting of V-arrangement cutter forms vee-cut later on workplace.For the light that lets reflectorized material reflect forms the light cone effect; The profile that obtains a desirable light cone pattern (the for example stack of six of above-mentioned all elements patterns) or disperse; Let same type of groove repeat with the groove of some; Each gash angle is different from the gash angle that closes in repetition period, and the size of gash angle becomes equal difference to increase or reduces.The quantity of different gash angles representes that with Q Q generally is not more than 20 in a repetitive.All the other two types are also repeated with identical gash angle with identical quantity.The result that different gash angles repeat is that the element on the reflectorized material is divided into a plurality of repetition big units, has comprised a lot of variform reflective elements in each big unit.Wherein have a reflective element criteria of right and wrong at least, this off-gauge reflective element has at least a face to depart from the corresponding surface of the reflective element of standard.Even the dihedral angle of these reflective elements not all is a quadrature, but still be counted as the reflective element of microprism, because it is similar to the desirable reflective element of microprism on shape and function.
The shape of 6 patterns that difform reflective element reflecting incident light obtains is different.The light cone pattern that the reflectorized material reflection of manufacturing of the present invention obtains is the stack of reflecting 6 patterns that obtain by all different reflective elements.Six of reflective element pattern shapes are can selecteed (through changing the size of reflective element dihedral angle) in the present invention, thereby obtain desirable light cone pattern or scattering profile.But this selection is restricted, because V-shaped groove cuts out the face of a plurality of reflective elements, V-shaped groove cuts out the face (the reflective element of two row is respectively on the both sides of V-shaped groove) of the reflective element of two row.If change the size of V-shaped groove angle, with changing this two row all reflective elements adjacent with V-shaped groove.Although such restriction is arranged in the design, still can design good structure through such mode.
Next will be described in detail reflectorized material structure of the present invention, obtain desirable light cone through specific mode cutting.
A kind of structure of improving diamond reflecting film reflective taper, the structure of said improvement diamond reflecting film reflective taper is made up of the reflective element of the prism of serial arrangement.
In order to realize the present invention better, further technical scheme is:

As a kind of job operation of the said goods, the present invention can also be:
A kind of job operation of improving the structure of diamond reflecting film reflective taper, the reflective element of said lens type is through the reflective element of three types V-arrangement diamond tool staggered cutting formation lens type.
Compared with prior art, one of beneficial effect of the present invention is:
Compared with prior art, the advantage of the structure of improvement diamond reflecting film reflective taper of the present invention is to optimize diamond reflecting film reflective taper structure, thereby diamond reflecting film reflective taper structure is had the following advantages:
(1) reflectorized material made from the present invention (like traffic sign etc.), the light cone pattern that reflecting incident light obtains can be controlled, to such an extent as to light will be required the people who sees and see greatly.For example, we can control the size at distribution of light cone light intensity and light cone angle.
(2) reflectorized material of manufacturing of the present invention has anisotropy preferably; Because positive unit and negative unit are arranged in the structure of reflectorized material; Negative unit has rotated 60 degree with positive unit relatively, two kinds superimposed reduced anisotropic inhomogeneous, thereby improved anisotropy.
(3) reflectorized material of manufacturing of the present invention is to make master mold through whole processing mode, and the V-arrangement cutter is to move along a straight line when face preparation, therefore can cut out reflective element accurately.Tie in respect to pin in addition and tie up technological and substrate combination technique, whole process technology can significantly reduce the labour, reduces cost.
These characteristics make reflectorized material of the present invention have good practicability.

Embodiment
Below in conjunction with embodiment the present invention is done to specify further, but embodiment of the present invention is not limited thereto.
" the reflective element " mentioned in the present invention is meant the cube structure on the reflector layer surface of reflectorized material, is single reflecting unit like (27) of Fig. 2; " the microprism reflectorized material " mentioned is meant that its reflector layer has the reflective element of cubical micro-prism structure, can be divided into reflective element of rescinded angle microprism and the reflective element of complete microprism according to the structure difference of reflective element.The characteristics of the reflective element of rescinded angle microprism of standard be exactly three faces of component be isosceles right triangle and orthogonal in twos, and three faces forming the complete microprism element of standard are squares and orthogonal in twos.What relate in the present invention is the rescinded angle microprism.Such reflectorized material also is known as " reflector " or " reflective membrane " sometimes; " reflective taper " mentioned is meant that the incident light material that is reflected reflects, and with the tapered light of the opposite direction diverging of incident light, the light of this taper is called reflective taper; " the V-arrangement cutter " mentioned is meant the diamond cutter that is similar to v-shaped structure that adopts when making master mold.
In order to obtain a desirable light cone effect; The present invention has proposed a kind of novel structure on the basis of rescinded angle microprism reflectorized material, this structure not only can produce desirable light cone effect, also has good processibility; Reduce manufacturing cost greatly, increase work efficiency.
As shown in Figure 1, the reflectorized material 100 of manufacturing of the present invention comprises: protective seam 110, body layer 120, reflector layer 130, sealant 140, adhesive linkage 150, peel off ply of paper 160.Protective seam be used for protecting reflectorized material to avoid receiving the destruction of external environment (for example the scratch of external carbuncle, oil stain and water accumulate in the light echo reflectivity of surface influence reflectorized material, and shielding of ultraviolet is alleviated the aging or the like of reflectorized material.); Body layer and reflector layer generally are to make through the method for mold pressing together, and its material is identical all to be transparent, and the lower surface of reflector layer has the reflective element 112 of a lot of microprisms, and these reflective elements have the function of returning incident light; Sealant is claimed " supporting layer " again, and its effect is to be connected with reflector layer and to produce the air bag 113 of sealing in the centre, and 114 places are connected with reflector layer at bearing, and the method for connection has ultrasonic soldering, thermal weld etc.; Adhesive linkage constitutes by having stickum, for example pressure sensitive adhesive, hot melt adhesive etc.Can directly be bonded at the place that needs stickup; The effect of peeling off ply of paper is the protection adhesive linkage, will peel off ply of paper before use earlier and open.Incident light as shown in the figure gets into from front surface 111, through protective seam and body layer, gets into reflector layer then, through three reflecting surface effects of reflective element 112, returns by former direction then.
What Fig. 2 described is the back view of standard rescinded angle microprism reflectorized material reflector layer, and the reflective element of a lot of compact arranged microprisms is arranged at the back side of reflecting material 10.As shown in Figure 2, these reflective elements are to be formed by the cutting of three types V-arrangement cutter, and three kinds of V-arrangement cuttves cuttings form three types V-shaped groove later.These three kinds of V-shaped grooves are respectively with M, N, O representative, and unidirectional V-shaped groove belongs to same type (for example groove 11 belongs to the V-shaped groove of O class all in same direction, and same groove 12 belongs to the V-shaped groove of M class, and groove 13 belongs to the V-shaped groove of N class).As shown in the figure, the V-shaped groove of M class is parallel with the Y axle, and the V-shaped groove of N class becomes 30 degree with angle between the x axle, and angle becomes 150 to spend between the V-shaped groove of O class and the x axle, is mutually into 60 degree angles between three kinds of V-shaped grooves.This three types V-shaped groove all be that equally spaced (for example, distance between the distance between the groove 11, the groove 12 and the distance between the groove 13 all are d.The size of reflective element is to determine that by distance between the V-shaped groove and V-shaped groove angle the H that reflective element and substrate are intersected is generally 25 microns to 1000 microns.
The size of interior groove angle of a repetition period of said same type of V-shaped groove becomes equal difference to increase or reduces.The size variation scope of said groove angle is ± 1 degree.
As shown in Figure 3, the reflective element 27 of standard rescinded angle microprism reflectorized material is made up of three faces, and these three faces are orthogonal in twos, and its two faces are given a line mutually, so three lines are arranged, the bottom surface of reflective element is an equilateral triangle.Like Fig. 2, reflective element 27 is made up of face 21,22,23, and these faces all are to be formed by the cutting of V-arrangement cutter.For example, face 21 is to be formed by the cutting of the V-arrangement cutter of M class, and face 22 is to be formed by the cutting of N class V-arrangement cutter, and face 23 is to be formed by the cutting of O class V-arrangement cutter.As before mention, the cutting of V-arrangement cutter forms V-shaped groove later, two dissimilar V-shaped grooves intersect at a line, and form a dihedral angle, the size of this dihedral angle is by the angle decision of V-shaped groove.For example, the groove 12 of M type intersects at the line 24 of reflective element with the groove 13 of N type, and has formed a dihedral angle.The size of this dihedral angle is by the decision of the size of these two gash angles; The groove 12 of M type intersects at a line (26) of reflective element with the groove 11 of O type, and forms a dihedral angle, and the size of this dihedral angle is by the size decision of these two gash angles; The groove 11 of O type intersects at a line 25 of reflective element with the groove 13 of N type, and forms a dihedral angle, and the size of this dihedral angle is the size decision of these two gash angles.In the reflective element of standard rescinded angle microprism reflectorized material, the size of these dihedral angles is 90 degree, and we claim that so reflective element is the reflective element of standard.
Like Fig. 4, be the sectional view of Fig. 2 B-B, description be the V-shaped groove structure of standard rescinded angle microprism reflectorized material, m1, m2, m3, m4 are respectively four grooves, all belong to the groove of M type, and be corresponding with M class groove among Fig. 2.Their gash angle equates that all its size is 70 degree 32 minutes.70 degree being defined as the standard angle of V-shaped groove in 32 minutes here, is 90 degree (in other words are exactly V-shaped groove be 70 degree 32 minutes, can obtain the standard retroreflective element) because the groove of this angle can make the dihedral angle of reflective element.The 18th, the axis of gash angle, it divides gash angle equally and perpendicular to the bottom surface.
As everyone knows, the quality of evaluation reflectorized material structure has four indexs: the wide-angle property of the anisotropy of incident light (Orientation), incident light (Entrance angularity), the homogeneity of reflective taper and the processibility of structure.
As shown in Figure 5; What describe is the anisotropy synoptic diagram of reflectorized material incident light, and the incident direction of light is represented by
.So-called anisotropy is exactly under the constant situation of angle θ; Incident light serves as that axle revolves three-sixth turn with the Z axle, and just
angle is become the process of 360 degree by 0 degree.Light echo reflectivity of each
correspondence this moment; Because reflectorized material particular structural; The light echo reflectivity that each
is corresponding is all inequality, is marked on all light echo reflectivity on the coordinate system then.
Like Fig. 6 is rescinded angle microprism reflectorized material anisotropy simulation result figure; The θ angle of its incident light is respectively 10 degree, 20 degree, 30 degree; The radius of a circle size is represented the size of light echo reflectivity among the figure, the size at numerical value representative
angle that circumference encloses.From figure, can see at 30 degree, 90 degree, 150 degree, 210 degree, light echo reflectivity when 270 degree, 330 are spent and be less than other angles at
; Especially when the θ of incident angle increases, performance obvious more.Optimal anisotropy simulation result figure is that all light echo reflectivity all equate or approaching.
As shown in Figure 7; What describe is the wide-angle property synoptic diagram of rescinded angle microprism reflectorized material; So-called wide-angle property is exactly an incident light under the constant situation in
angle; The θ angle changes, and variation range is 0 to spend to 90 degree.Equally, the corresponding light echo reflectivity in θ angle is marked on all light echo reflectivity on the coordinate then.Like Fig. 8; Be rescinded angle microprism reflectorized material wide-angle property simulation result figure,
angle of its incident light is 30 degree.Horizontal ordinate is represented the size at θ angle, and ordinate is represented the size of light echo reflectivity.From figure, can see that along with the increase of θ angle, the light echo reflectivity reduces.Ideal results is that all light echo reflectivity all equate or near (what reduce is good more more gently).
Can know that according to background knowledge the method that forms light cone has three kinds: (1), make the face out-of-flatness (being similar to diffuse reflection) (2) of reflection element, through the diffraction of light effect.(3), change the geometry of reflective element, make three dihedral angles of reflective element depart from orthogonality relation.In the present invention, obtain desirable light cone effect through the size that changes dihedral angle.As shown in Figure 9, description be that the light cone of rescinded angle microprism reflectorized material forms synoptic diagram.Incident light is injected reflectorized material along certain direction; After the reflectorized material effect; Light reflects along the form of incident light axis (line of incident light incident direction is the incident light axis) with diverging light, and the light of dispersing like this is called reflective taper, and the angle of general light cone is less than 1 degree.This light cone is very necessary in the middle of the utilization of reality.Sign board when light is made by reflectorized material from the car light directive returns car light then.Therefore driver's eyes and car light can't see sign board, and have been had after this special light cone effect not in same position, and the driver just can see sign board.In practical application, we can not adopt the Counter-reflection membrane material with microprism array structure of standard.Because incide the surface of Counter-reflection membrane material of standard when the light of a branch of collimation after with microprism array structure; The light that reflects will return along the incident direction of light; Can't form one 1 reflective taper about degree; Therefore the Counter-reflection membrane with microprism array structure of standard does not have practical value, but its design feature and reflective characteristic are the bases that we study.
Deliver in July, 1971 from H.D.Eckhardt that we know the face of the reflective element of rotation the paper that paper and N.E.Rityn about optics " naive model of cube reflector phenomenon " deliver " optical principle of cube microprism ", the face that makes it is not orthogonal or quadrature.Can make the light that is reflected by reflective element be dispersed into the luminous point (opposite direction along incident light is a central distribution) of six different directions like this.Like Fig. 9, we set up a local coordinate on incident light axis, and the Z axle overlaps with incident light axis, and the X axle is parallel with the X axle of world coordinates, and the Y axle is vertical with the X axle.To return the luminous point that comes then and be marked in the coordinate, so just form the simulation result figure of light cone.Shown in Figure 10 a-10d, description be the simulation result figure of the light cone that obtains after the single reflective element reflecting incident light after dihedral angle changes.The numeral that circumference encloses among the figure is described the position of light, and radius of a circle is represented the pyramid size of light cone, and the angle of general light cone is less than 1 degree.The incident angle of light of four figure all is identical; θ is 15 degree,
be 20 degree.What Figure 10 a represented is the not change of dihedral angle of reflective element, returns by former road through the light after the reflection, does not depart from the incident light axis; Figure 10 b representes is that a dihedral angle of reflective element has increased 9 minutes (spending with the dihedral angle 90 of the reflective element of standard relatively), and reflected light departs from the incident light axis line and formed two luminous points; What Figure 10 c represented is that two dihedral angles all increase by 9 fens, and reflected light departs from the incident light axis line and formed four luminous points; What Figure 10 d represented is that three dihedral angles all increase by 9 fens, and reflected light departs from the incident light axis line and formed six luminous points.The pattern that forms six points after the reflective element reflecting incident light is known as 6 patterns.The light cone pattern is formed by stacking a lot of different 6 patterns.
We know, the size of dihedral angle is that in other words, the size that changes dihedral angle can realize through the angle that changes V-shaped groove by the angle decision of V-shaped groove.Along with the variation of V-shaped groove angle, corresponding dihedral angle also can change.Like Figure 11 is the amplification effect figure of the single reflective element of Fig. 2 (27).This reflective unit have three dihedral angles, is respectively dihedral angle D1-2, dihedral angle D2-3, dihedral angle D1-3.Because face 21,22,23 is made up of groove 11,12,13 respectively, so groove 11,12,13 is determining dihedral angle D1-2, D2-3, D1-3.Can be known that by Figure 11 dihedral angle D1-2 is made up of groove 12,13, dihedral angle D2-3 is made up of groove 11,13, and dihedral angle D1-3 is made up of groove 11,12, and wherein per two grooves determine a dihedral angle.
For the light that lets reflectorized material reflect forms light cone; The profile that obtains a desirable light cone pattern (the for example stack of six of above-mentioned all elements patterns) or disperse; Let one type of groove repeat with the groove of some; Each gash angle is different from the gash angle that closes in repetition period, and the size of gash angle becomes equal difference to increase or reduces.The quantity of different gash angles representes that with Q Q generally is not more than 20 in a repetitive.All the other two types are also repeated with identical gash angle with identical quantity.The result that different gash angles repeat like this is that the element on the reflectorized material is divided into a plurality of repetition big units, has comprised a lot of variform reflective elements in each big unit.Wherein have a reflective element criteria of right and wrong at least, this off-gauge reflective element has at least a face to depart from the corresponding surface of the reflective element of standard; Even the dihedral angle of these reflective elements not all is a quadrature, but still be counted as the reflective element of microprism, because it is similar to the reflective element of desirable microprism on shape and function.
Figure 12 is the back view of the representative rescinded angle microprism reflectorized material reflector layer of the present invention, and three types groove is arranged among the figure, is respectively M, N, O.M1, m2, m3, m4 belong to the groove of M class; And the size of gash angle is all different, and the size of gash angle becomes equal difference to increase or reduces, and the difference between them representes that with β (the β angle can be for just also can be for negative; When be on the occasion of the time gash angle equal difference increase, gash angle equal difference reduces when for negative value.）。For example m1 is the gash angle of standard, and m2 adds a β for the standard trench angle, and m3 adds 2 β for the standard trench angle, and m4 adds 3 β for the standard trench angle, is that one-period repeats with these four grooves then.The groove of same N, O class also repeats in this manner.The quantity that different gash angles repeat can change with Q.Q=4 here, the Q value is big more, and reflective elements different in the big unit is many more.
Figure 13 is the sectional view of C-C among Figure 12, and the equal difference of having used a kind of mode of exaggeration to show gash angle changes.M1 among the figure, m2, m3, m4 are consistent with m1, m2, m3, m4 among Fig. 8, and their gash angle has nothing in common with each other, and line (18) is the groove axis, and dotted line is the standard trench angle.The both sides of groove are the increase of center line equivalent with groove axis (18) or reduce gash angle that its scope is less than ± 1 degree.Like figure, m1 is identical with the standard trench angle, and m2 adds a β for the standard trench angle, and m3 adds 2 β for the standard trench angle, and m4 adds 3 β for the standard trench angle.Repeat with these four gash angles then.
