Description
Technical field
The utility model relates to the device that goes out visible sign on reflectorized material with Laser Processing, is especially going out a plurality of be positioned on the same laser mark but can only be by the device of the observable image of different angles on the reflectorized material of basic object with Laser Processing.
Background technology
The sign of commodity (Marking claims labeling again) is except there being certain vision U.S., and certain durability be the more important thing is and wanted can prevent to be copied by other people.Therefore, the high laser mark of part all use difficulty of name brands is promptly gone up at ready-made commercially available reflectorized material (Reflective Material) and is made pattern and literal with laser at present.The laser mark that is used for clothes is in order to stand repeatedly washing together in company with these clothes, so generally adopt the reflectorized material of fabricbase or plastic foil base and so on.
General as shown in Figure 1 commercially available reflectorized material 100 is all formed by matrix 11, refractive body 12 with the supporting layer 13 that those refractive bodies are fixed on this matrix; Matrix 11 can be cloth, paper or plastic foil etc.; It is the spheroidal transparent substance that refractive body 12 can be.When this refractive body was spheroidal, this refractive body in fact can only refracted ray, and real reflection (light) effect is finished by this supporting layer.In structure shown in Figure 1, all can reflect away by former direction from the incident ray of any direction.
The reflex of the multiaspect shape refractive body 14 among Fig. 2 and spheroidal 12 different, this refractive body 14 shown in the figure is a tetrahedron, it fully by perpendicular to the light of a faceted pebble incident in polyhedron total reflection and still penetrate by this plane of incidence.So the reflex mechanism of Fig. 1 and Fig. 2 is diverse.
The way that processes visible mark with laser on reflectorized material is of long duration, the US 6 that filed an application in 1997 for example, 231, just with laser beam the reflective material of region of interest on the reflectorized material is gasified partially simply among 196 B1, thereby cause the sign that reveals dark pattern and character in the bright background.The US 6 that filed an application in 1998,217, the method that proposes among 175 B1 goes a step further than said method, it is to burn the bottom of the spherical refractive body of reflectorized material region of interest flat with laser beam, thereby make the observer perpendicular to the reflectorized material plane can see dark pattern and character, the observer of offset from perpendicular certain angle then can only see bright background and cannot see any pattern and character.
Fig. 3 is that the reflective schematic diagram after putting down is burnt in spherical refractive body 12 bottoms of prior art.As seen from Figure 3, ball 12 bottoms are made into a plane, have not played the supporting layer of reflex certainly on this plane.Thereby when incident ray not reflection during perpendicular to reflectorized material incident, the observer can't see reverberation in certain scope, therefore just see dark pattern and character, shows among the figure that this scope is 30 °, and this angle is decided by the diameter on plane.But when exceeding this scope observation,,, only seen a slice light ground so cannot see pattern and character because this plane is inoperative in this angle.Therefore, the flesh and blood of prior art is just the bottom of relevant spherical refractive body 12, and promptly the reflection characteristic of double second plane of incidence of first exit facet of incident ray destroys, and incident light can't be reflected.Because every circular refractive body 12 has only a bottom, so the method for prior art can only be done a sign at most on same spherical refractive body 12.
The sign of above-mentioned first prior art is because too simply thereby very easily copied by other people.In addition perpendicular to the laser beam of reflectorized material when the reflective material gasification that makes relevant position, injure exposed support matrices around the reflective material easily.And this method revealed with the same at bowl dish surface etching sign, do not have what special optical effect.Though second above-mentioned prior art has optical effect to a certain degree, can only be used for spherical refractive body, can not be used for the refractive body of multiaspect shape.And to be processed into a plane to the bottom of the spherical refractive body of ready-made opaque matrix reflectorized material be very inconvenient, can destroy the original matrix of reflectorized material.Thereby this method can't purchased ready-made reflectorized material small and medium sized business adopt.Main is this method and the architectural characteristic of underusing reflectorized material, thereby required difficulty is turned one's coat and not high when imitated.
Therefore, need a kind of architectural characteristic that can make full use of reflectorized material, can prepare the processing unit (plant) of the high sign of imitation difficulty.

The specific embodiment
Fig. 4 is the utility model device laser beam is fired when sign on reflectorized material a schematic diagram, though what draw in Fig. 4 is spheroidal refractive body 12, is identical for the effect of the refractive body 14 of polyhedron shape.The laser beam that adopts can shine the scope greater than a refractive body sphere at least.Processing laser beam of the present utility model shown in Fig. 4 is not to shine to refractive body 12 along the direction of vertical refractive body bottom, but with certain angle, promptly the incidence angle of any angle between 10 ° to 80 ° is according to first plane of incidence to refractive body 12 tops, make this face produce small gasification and cause hair, therefore make the incident ray scattering or to a plurality of directions refractions, thereby can not reflect to incident direction; When the direction of this incidence angle is observed, the face that causes hair through gasification is a dim spot, and other non-irradiated refractive bodies are bright spot.The benefit of laser beam oblique illumination refractive body is to have two shadow surface BD and AC that not exclusively cover mutually on same spheroidal refractive body 12 at least, wherein cambered surface CD is mutual cover part, cambered surface BC and AD are cover part not, thereby can do two different signs.Laser selective ground gasification with a certain incidence angle earlier causes the one side that hair is respectively organized refractive body, this respectively organizes the another side of refractive body to cause hair with the gasification of the laser selective ground of another incidence angle again, each self-forming dim spot and bright spot because the reflectivity that causes hair side and unlikely hair side is different, and different dim spot and the bright spots of many density just formed picture, thereby can utilize more than one to write down and reflect different images on same refractive body.
In addition, also can select one group of refractive body according to the pattern of laser mark again, shine the surface of this group refractive body from a direction with laser with an incidence angle again, can form the combination that a cover causes hair side and unlikely hair side again, from and form a kind of pattern of video.
Thereby can process a plurality of be positioned on the same laser mark but can only be with laser on the reflectorized material by the observed image of different angles.
The rest may be inferred, as long as also there is unlikely hair side in described refractive body, theoretically, just can make a lot of different patterns, and just resolution ratio is lower.
If refractive body is a polyhedron shape, then have nothing in common with each other owing to each polyhedral attitude, can be more more so on same reflectorized material, can do the number of sign, just the brightness and contrast is just weaker certainly.
Fig. 5 is the schematic diagram that the utility model device is selected processing laser beam incident angle for use.Drawn among Fig. 5 from five spheroidal refractive bodies of right-to-left 12-1,12-2,12-3,12-4,12-5.Last half circular arc of ball 12-2 is subjected to from right-hand and each laser beam irradiation processing with 30 ° of angle incidents of left, as seen from the figure, with regard to the right first half of ball, be not to be subjected to the common irradiation of two groups of light only from the intersection point A of right-hand minimum light and ball 12-2 with from one section cambered surface between the point of contact D of the highest light of left and ball 12-2.Also be that this section cambered surface only is subjected to process from the irradiation of right-hand light.As a same reason, ball 12-3 be from about the incidence angle of light respectively be that 45 ° result, the incidence angle that ball 12-4 is left and right sides light respectively are 60 °.This shows that the not overlapping area of the big more then left and right sides of incidence angle light (being the A-D cambered surface) is also big more, but the irradiation less than area also big more.Ball 12-5 is that the incidence angle from right-hand light is that 30 ° of incidence angles from the light of left are 60 ° result.The right first half of ball 12-5 (being the quadrant arc) though maximum not overlapping area AD arranged, at left first half faying surface not just.If therefore about the incidence angle of laser respectively be 45 ° comparatively desirable, like this, about two signs can both obtain optimum resolution.Certainly, in order reason such as to maintain secrecy, use the laser beam of left and right sides different incidence angles degree can increase the difficulty that other people copy.Though each ball is very big at the left and right sides at ball top light faying surface in Fig. 5, but because when light during with big incidence angle incident category of glass medium, a large amount of light can reflect away, and having only in a small amount just can incident, thus in fact the overlapping phenomenon of left and right sides light the image pattern mark is not serious like that.
Fig. 6 A and Fig. 6 B be respectively the utility model device an embodiment face schematic diagram with side-looking, in the drawings as seen, this device comprises: falsework, it comprises workbench 40 and support, this support comprises the column of being located on this workbench 50; Laser aid 30 is located on the described support, is placed vertically down on the workbench 40 by transverse arm 60, column 50, and the emission laser beam shines on the described refractive body.The outer arcuate band holder 70 that has an arc opening bracket 80 that makes progress to be used for accepting matching with it on the workbench is carved with angle index on band holder 70 or bracket 80.What be with holder 70 is a square breach to upper part, is used for bearing reflectorized material band 100 (not shown)s.Certainly, notch geometry can change, but comprises a plane at least, is shelved on this plane for reflectorized material.Fig. 6 A rotates to different angles with the relative respectively bracket 80 of band holder 70 that Fig. 6 B shows.Because band holder 70 can be relayed to the angle of any institute palpus easily at bracket 80, both one of be carved with angle index) and fixing on this angle, for example adopt end face pressing plate 81 (only being presented among Fig. 6 A) to fix, thus be placed in the square breach of band holder 70 reflectorized material band 100 just and the laser beam of penetrating under vertical formed the angle of palpus.Reflectorized material band 100 send the volume warp let-off of device (not shown) intermittence ground to cross band holder 70 by the volume that is positioned at the vertical two ends of workbench, when being with 100 to rest in the band holder 70, just scans processing by laser aid 30.After processing one side, can be reflectorized material band Rotate 180 ° so that the processing another side.Can optionally change the angle between band holder 70 and the laser aid 30 this moment.
Certainly, can not establish on the workbench 40 and drag seat 80, but directly on workbench 40, offer an arc groove, be complementary with the arcuate zone holder.Perhaps, establish support and will be with holder unsettled, this support has a bar axle to be connected with band holder 70, and this bar axle is rotatable, rotates thereby drive band holder 70, regulates incidence angle.
In addition, the adjusting of incidence angle for convenience and enlarge the adjustable range of incidence angle can also allow the bracket 80 be the center of circle with self axle center, horizontally rotates in allowed limits in the plane of workbench.
When producing in enormous quantities, certainly very cause many laser aids 30 with two.Nor necessarily allow laser aid 30 vertically place, and can allow reflectorized material band 100 be parallel to the table top of workbench 40, laser aid is placed obliquely.When regulating incidence angle when just doing like this because will the bigger laser aid 30 of mobile weight and can be very inconvenient.
In a word, the band holder of this device and go up the shape of breach, concrete set-up mode, the laser aid of band holder be fix or movably or the like, no matter take which kind of mode, as long as make the incidence angle of laser beam irradiation refractive body adjustable, and the angle that can reach required incidence angle gets final product.
Laser and computer that enforcement the utility model device is used all are prior aries, and for example laser generator can adopt neodymium YBAG ytterbium aluminum garnet (NdYAG), carbon dioxide (CO
2) or semiconductor pumped (diode-pumped) laser and so on device, the computer (not shown) is used for controlling generating device of laser and laser reflex sweep device.Commercially available reflectorized material band is web-like normally, can utilize the batch (-type) Webbing take-up device to make this band carry out laser scanning processing when pausing by working position (i.e. band holder 70).When the laser of suitable intensity scans when respectively organizing refractive body 12 or 14 successively with certain angle, this group refractive body illuminated that face just produce corresponding gasification and cause hair, thereby this group refractive body just is rendered as a dim spot when observed under this angle.The refractive body of respectively organizing that is not scanned remains a bright spot.The dim spot of many different densities and bright spot are just formed a picture.In order to improve speed of production, left and right sides light source is preferably respectively with a laser aid.When the sign area be 1.5 centimeters high 5.0 centimeters wide, laser energy is 10 watt-hours, need only just can scan completion of processing 30 seconds.This is an experimental data of the present invention, in fact process time can because of the angle of the kind of the complexity of the character of the reflectorized material that adopted, pattern, laser, incident ray, or the like former thereby different.
When checking or observe the laser mark made from device of the present utility model 100, no matter illuminating ray or observer will just can obtain the most clearly video to sign 100 along the direction directive/prestige that adds man-hour, as shown in Figure 7.For example the image on the right of the laser mark made of the utility model among Fig. 7 scans with 60 ° of incidence angles and makes, and therefore illuminating ray (representing with torch among the figure) and observer's (representing with human eye among the figure) will just can see optimum efficiency in the direction of 60 ° of incidence angles when observing.The image on the left side scans with 30 ° of incidence angles and makes among Fig. 7, therefore must the image pattern target just can see optimum efficiency from directional lighting and observation along 30 ° of incidence angles like that.In Fig. 6, the image that presents in the bright background of being seen by two different directions is diverse, and what for example direction was seen is literal, and what another direction was seen is pattern.
Incidence angle described in the literary composition all refers to the direction of incident ray and perpendicular to acute angle folded between the reflectorized material in-plane.
