Description
Technical field
The invention belongs to optical technology detection field, and in particular to a kind of safety glass identifier and recognition methods.
Background technology
Simple glass due to being easily broken, and it is broken after easily the person is caused harm and people's sight line of gradually fading out.With
Flourishing for touch-control industry, the specification requirement of touch-control product in itself is also increasingly strict, because contact panel is applied by outside
Plus-pressure goes to carry out the function mode of inductive component so as to reach using effect, therefore the mechanical compressive resistance of product is all big enterprises
Important specification and index.Under this market background, safety glass arises at the historic moment.Also known as strengthened glass, it is safety glass
A kind of prestressed glass, usually using method chemically or physically, compression is formed in glass surface, and glass bears first during external force
Surface layer pressure is first offset, so as to improve bearing capacity, thus safety glass is widely used in building doors and windows, glass curtain wall, electricity
The fields such as sub- instrument.Just because of the such many advantages of safety glass, effectively identification how is carried out to safety glass turns into tempering
The focal issue that glass applications business is concerned about.
Due to after glass tempering compression can be produced on its surface, thus safety glass is identified in the market
The stress of safety glass is measured by using optical waveguide technique mainly, i.e., using refracting prisms, REFRACTIVE LIQUID, glass to be measured
Glass surface produces evanescent wave, with reference to photoelastic effect, carries out the measurement of safety glass surface stress.Such as Chinese utility model patent
ZL201420643584.X discloses a kind of New automatic glass surface stress gauge, including instrument body, eyepiece, light source and double
Refracting prisms, the birefringent prism protrudes from instrument body upper surface and the light positioned at light source projects direction simultaneously, described
The front end of eyepiece is located on the light refractive direction of birefringent prism, and an industrial camera is installed in the rear bottom of eyepiece, described two-fold
Penetrate directly over prism and a liquid-drop machine is installed, the industrial camera, liquid-drop machine connect computer processor by data wire.
When measuring safety glass surface stress using the stress ga(u)ge, measuring samples are placed on birefringent prism first, then by counting
Calculation machine processor controls liquid-drop machine that a small amount of REFRACTIVE LIQUID is added dropwise to glass surface to be measured, because the glass processed by tempering is in its table
Face can produce stressor layers, and the light that light source sends incides glass surface to be measured, birefringence is produced in the presence of Surface stress layer,
Two light beams that beam polarization direction is orthogonal and the direction of propagation is different are formed, the two light beams after industrial camera by being converted into
It is easy to the bright fringes or dark fringe of identification, finally by calculating interference fringe information so as to obtain safety glass surface stress value.
Although using the New automatic glass surface stress gauge not only can to glass, whether tempering is identified, but also can be with essence
Really and safety glass surface stress efficiently is calculated, but, it is not difficult to find out more than, this stress ga(u)ge complex structure, cost
It is higher, and need for measuring samples to be placed on birefringent prism surface during measurement and contact to be totally reflected, contact
During scratching easily is caused to measuring samples, have impact on the aesthetic appearance and performance of measuring samples.In addition, should to improve
The certainty of measurement of power instrument, needs that REFRACTIVE LIQUID is added dropwise to measuring samples surface in measurement process, and REFRACTIVE LIQUID to a certain extent can
Harmful effect is produced to health of human body, and as a kind of consumptive material, undoubtedly also increases testing cost.Meanwhile, this metering system
Still need to wipe measuring samples surface after end, so as to increased the complexity of whole detection operation, waste time and energy,
Have impact on measurement efficiency.

8. safety glass identifier according to claim 7, it is characterised in that the photographing element is area array CCD.
9. a kind of recognition methods of safety glass, it is characterised in that comprise the following steps：
（1）One piece of level crossing is placed on detection platform measurement position, the light that light source sends is totally reflected laggard through the level crossing
Enter to photographing element and be imaged, the image that the photographing element will be obtained is sent to analysis element, and the analysis element is taken the photograph to described
The image that element sends is analyzed treatment, obtains overall light intensity I now0；
（2）The non-safety glass with measuring samples same material is taken as the first reference sample, first reference sample is obtained
Critical angle C；First reference sample is placed on detection platform measurement position, the light that light source sends is incided with γ angles
First reference sample, and γ<C, the light enters into photographing element and is imaged after being reflected through first reference sample, institute
State the image that photographing element will obtain and be sent to analysis element, the analysis element is carried out to the image that the photographing element sends
Analyzing and processing, obtains reflective light intensity I now1, by I1Divided by I0, obtain the reflectivity R of first reference sample1, i.e. R1=
I1/I0；
（3）Measuring samples are placed on detection platform measurement position, the light that light source sends incides measuring samples with γ angles, and
γ<C, the light enters into photographing element and is imaged after being reflected through measuring samples, the image that the photographing element will be obtained sends
To analysis element, the analysis element is analyzed treatment to the image that the photographing element sends, and obtains reflected light now
Strong I2, by I2Divided by I0, obtain the reflectivity R of measuring samples2, i.e. R2=I2/I0；
（4）By R2With R1Make comparisons, judge measuring samples whether tempering；If R2With R1It is close, then judge that measuring samples are non-steel
Change glass；If R2With R1Difference is larger, then judge that measuring samples are safety glass.
10. the recognition methods of safety glass according to claim 9, it is characterised in that also including to measuring samples whether
The step of tempering is further confirmed that, including：
（5）The safety glass with testing sample same material is taken as the second reference sample, second reference sample is placed
In detection platform measurement position, the light that light source sends incides second reference sample, and γ with γ angles<C, the light
Enter into photographing element after being reflected through the second reference sample to be imaged, the image that the photographing element will be obtained is sent to analysis elements
Part, the analysis element is analyzed treatment to the image that the photographing element sends, and obtains reflective light intensity I now3, by I3
Divided by I0, obtain the reflectivity R of the second reference sample3, i.e. R3=I3/I0；
（6）R is obtained respectively2With R3Difference and R2With R1Difference, if R2With R3Difference absolute value be less than R2With R1's
The absolute value of difference, then can confirm that measuring samples are safety glass；If R2With R3Difference absolute value be more than R2With R1Difference
The absolute value of value, then can confirm that measuring samples are non-safety glass.
