Description
Technical field：
The present invention relates to a kind of production method of the false proof water ripples of reflective membrane.
Background technology：
Reflective membrane is the reflectorized material that a kind of surface grafting has many glass microballoons, is usually used in warning labeling, increases applied to passive
Add the occasions such as the advertisement of light intensity, direction board, warning guardrail, under irradiation of the night in light emitting sources such as car lights, can strong reflection light echo,
Pedestrian, driver etc. is facilitated clearly to see object and shown content clearly.Present license plate all uses reflective membrane as lining
Bottom, convenient vehicle below can be clearly seen that front vehicles, and convenient and safe meeting drives.
Glass microballoon is planted in substrate can reflect the light of various different angle incidences, the bottom reflection face of glass microballoon
It is that there is certain thickness reflectorized material, such as aluminium film.The ability of reflection light is lost if reflectorized material is by damage, just
When face light is incident, the place of no reflected light takes on shadow, if take certain method by reflecting material on demand
Damage it, it is possible to a pattern is formed under glass microballoon, this pattern is because survivable under glass microballoon, just
It can be used as dark line.
Therefore, for it is easier to go deep into glass microballoon bottom removal reflectorized material with a kind of method.Laser is that one kind can be with
Reflecting material is reached through glass microballoon, therefore selects one kind not absorbed by glass microballoon, but can be absorbed by reflectorized material
Laser, reflectorized material is etched beneficial to the high-energy light beam guiding of laser.
But solve the etching problem on reflectorized material surface, required dark line figure can be obtained, if this figure
It can only can see that and other directions are invisible that picture can be one fixed and stiff in the incident angular direction of laser when making
Image.This is because laser when inciding reflectorized material surface, has been accumulated the light beam into a branch of only tens microns, anti-
One tens microns wide of etching wire casing has been etched in luminescent material, has not been by other large stretch of places of laser ablation, light
Total reflection, it not can be appreciated that dark line, just can be at one if the etching wire casing of different angle can continuously be etched on reflectorized material
Dark line is continuously seen in angular field of view.If same pattern, when changing angle, the incoming position between different angle
Difference, i.e. incident ray translate, and if when incident angle changes, the change for translating position is also continuous, then has been made
Cheng Hou, image not only can see in different visual angles angle, but also be dynamic mobiles.If one in the making of reflective film surface
Group water ripples, ripples can equally teetertotter like water wave, and pattern is lively.
The content of the invention：
The purpose of the present invention is pattern is lively, can not alter, the system of the false proof water ripples of reflective membrane not easily to fall off and easy to make
Make method.
The present invention is achieved through the following technical solutions：A kind of production method of the false proof water ripples of reflective membrane, including light source
System, imaging system and control system, comprise the following steps that：
A, light-source system use, which can be produced, is absorbed by reflectorized material, not by the optical fiber of the wavelength 1064nm laser of glass microballoon absorption
Laser；
B, imaging system is two groups, and one group is just imaged, and one group counter to be imaged, and every group of imaging system turns by light-beam forming unit and at a high speed
Microscope group into；
C, two groups of imaging systems are installed on a unified platform, and platform is made of servomotor screw, control system control
The movement of platform, so as to produce the upper and lower translation change of pattern incidence angle, platform just adjusts up and down；
D, control system is made of Industrial PC and control software, control software control Laser emission, high-speed rotating mirror generation linear light band,
Pattern upper and lower translation, the function of generating gradient pattern；
E, bin stock mechanism, preceding unreeling structure, storing roller and rear unreeling structure are arranged successively, are carried out reflective membrane and are continuously wound production；
F, the light beam that laser is sent generates outbreeding light beam, outbreeding light beam is before reflective membrane is incided after light-beam forming unit
Reflected by high-speed rotating mirror, in the light beam injection reflective membrane for producing continuous periodically-varied incident angle, by varying incidence angle
Mode, make pattern be just imaged and it is counter be imaged, make a positive imaging water ripples and an anti-imaging water ripples on the reflecting film
Pattern.
Preferably, the driving of reflective membrane is driven by servomotor driving drive roll.
Preferably, high-speed rotating mirror is made of hexagonal mirror, is coated with golden film on speculum, adjust high-speed rotating mirror with it is anti-
The distance of light film, changes the visible angle and image height of image.
The present invention has the following advantages compared with prior art：Pattern is lively, can not alter, not easily to fall off and making side
Just.
Brief description of the drawings：
Fig. 1 is the principle of the present invention figure；
Fig. 2 is the live-roller layout viewing of the present invention；
Fig. 3 is the system layout viewing of the present invention；
Embodiment：
With reference to specific embodiments and the drawings, the invention will be further elaborated, but the present invention is not limited to following implementation
Example.
As shown in Figure 1, 2, 3, the production method of the false proof water ripples of a kind of reflective membrane, including light-source system, imaging system and
Control system, is specially：Light-source system use can produce the wavelength 1064nm for being absorbed, not absorbed by glass microballoon by reflectorized material
The optical fiber laser of laser；Imaging system is two groups, and one group is just imaged, and one group counter to be imaged, and every group of imaging system is by beam shaping
Device and high-speed rotating mirror composition, high-speed rotating mirror is made of hexagonal mirror, and golden film is coated with speculum, adjust high-speed rotating mirror with
The distance of reflective membrane, changes the visible angle and image height of image；Two groups of imaging systems are installed on a unified platform,
Platform is made of servomotor screw, the movement of control system control platform, so that the upper and lower translation for producing pattern incidence angle becomes
Change, platform just adjusts up and down；Control system is made of Industrial PC and control software, control software control Laser emission, height
Fast tilting mirror generation linear light band, pattern upper and lower translation, the function of generating gradient pattern；Bin stock mechanism, preceding unreeling structure, storing roller and
Unreeling structure is arranged successively afterwards, it is ensured that the reflective membrane tensile force at laser making is consistent, stable movement, and it is continuous to carry out reflective membrane
Winding production, the driving of reflective membrane are driven by servomotor driving drive roll, and rotating speed is steady；The light beam that laser is sent is through light beam
After apparatus for shaping, outbreeding light beam is generated, outbreeding light beam is reflected before reflective membrane is incided by high-speed rotating mirror, produces the continuous cycle
In the light beam injection reflective membrane for sexually revising incident angle, by varying the mode of incidence angle, pattern just imaging and anti-imaging, anti-
Penetrate on film and make a positive imaging water ripples and an anti-imaging water ripples pattern.
