Description
Technical field
The present invention relates to a kind of reflective chemical liquid and smear uniformity detecting method and device, specifically have employed lenticular lenses to match with CCD, the method detect the uniformity of the bigger transparent liquid medicine painting of the viscosity spread upon on transparent glass sheet in uniform thickness and device, belong to environmental protection tests method and apparatus field.
Background technology
In environmental protection tests, it is often necessary to carry out chemical analysis at the scene, inspection is often used some and is already coated with the sheet glass wiping medical agents.Medicinal liquid on these sheet glass it is generally required to be coated with and wipe and dry in laboratory.At present, smearing of these medicinal liquids is mainly completed with equipment by artificial.The generally circular in cross section sponge block of turning round of the equipment used, after being dropped on sponge block by medicinal liquid, sponge block high speed rotating on the glass sheet from top to bottom by liquid medicine painting simultaneously.Owing to sponge is turned round the abrasion when application, and the uniformity of reason the makes liquid medicine painting such as the viscosity of some medicinal liquid is very big it is difficult to ensure that.Therefore, in the urgent need to researching and developing a kind of equipment that can automatically the uniformity of the bigger medicinal liquid automatically smeared of this viscosity be detected, and currently without this equipment.
Lenticular lenses is a kind of object that a kind of surface is imprinted with intensive uniform stripe.The refraction of light refer to light from air be slanted through other media time, the direction of propagation changes, so that light is at the intersection generation deviation of different medium.The present invention applies the refraction principle of light dexterously, have employed the mode by observing the grating fringe deformation being placed under the clear glass scribbling transparent medicinal liquid, have developed a kind of device that can be used to detect the uniformity of transparent medicinal liquid.
Summary of the invention
The invention provides a kind of reflective chemical liquid and smear uniformity detecting method and device.
The present invention is achieved by the following technical solutions: a kind of reflective chemical liquid smears uniformity detecting method, adopt lenticular lenses, CCD, lenticular lenses is close to the lower section being placed on the sheet glass scribbling transparent medicinal liquid, and application CCD is passing through the striped in the sheet glass lenticular lenses with transparent medicinal liquid with the position shooting at an angle of the normal of sheet glass.Then, the thickness evenness of the transparent medicinal liquid smeared is differentiated by analyzing the deformation of striped.The method application lenticular lenses on should have parallel, width is consistent with spacing and in white and black striped, if the striped on the image that CCD photographs is still parallel and spacing is consistent, illustrate that the thickness smearing transparent medicinal liquid on the glass sheet is uniform, if the striped on the image photographed has obvious deformation, or the depth of parallelism changes, then the transparent medicinal liquid illustrating to smear in uneven thickness.Adopt medicinal liquid of the same race, after demarcating, the thickness difference of the medicinal liquid smeared can be detected quantitatively.
A kind of reflective chemical liquid smears uniformity detection, it is made up of with CCD lenticular lenses, it is characterized in that: lenticular lenses is close to the lower section being placed on the sheet glass scribbling transparent medicinal liquid, the normal of CCD axis and sheet glass is placed on the top of sheet glass at an angle, enable CCD intactly to photograph the stripe pattern in lenticular lenses, the striped that described lenticular lenses is printed on should parallel, chequered with black and white, width is consistent with spacing and in sharp contrast.
The usefulness of this invention is, solves the qualitative and detection by quantitative problem of the uniformity of the high-speed automated transparent medicinal liquid smeared at present；By observing and the sheet glass normal CCD at an angle stripe pattern shot, if transparent medicinal liquid is all consistent with sheet glass thickness on radiation direction respectively, then the inevitable still one group of striped that width is equal, spacing is consistent, parallel to each other of the grating fringe transmitted；If the bar in image there occurs bending or occurs in that the phenomenons such as not parallel, then indicate the medicinal liquid smeared in uneven thickness, and the concrete numerical value of difference on thickness can be calculated the amount of deformation.
Accompanying drawing explanation
Accompanying drawing 1 is the vertical view pattern of lenticular lenses；
Accompanying drawing 2 is the structural representation of the present invention, and wherein 1 is lenticular lenses, and 2 is CCD；
Lenticular lenses is close to the lower section placement of sheet glass as can be seen from Figure 2, and the placement of CCD is with the normal of sheet glass at an angle.
Detailed description of the invention
A kind of reflective chemical liquid smears uniformity detecting method, adopt lenticular lenses 1, CCD2, lenticular lenses 1 is close to the lower section being placed on the sheet glass scribbling transparent medicinal liquid, application CCD2, passing through the striped in the sheet glass lenticular lenses 1 with transparent medicinal liquid with the top position shooting at an angle of the normal of sheet glass, differentiates the thickness evenness of the transparent medicinal liquid smeared by analyzing the deformation of the striped photographed.The method application lenticular lenses 1 on marking should be parallel, width is consistent with spacing, in white and black striped, if the striped on the image that CCD2 photographs is still parallel and spacing is consistent, illustrate that the thickness smearing transparent medicinal liquid on the glass sheet is uniform, if the striped in image has obvious deformation, or the depth of parallelism there occurs change, then the transparent medicinal liquid illustrating to smear in uneven thickness.Adopt medicinal liquid of the same race, after demarcating, the thickness difference of the medicinal liquid smeared can be detected quantitatively.
A kind of reflective chemical liquid smears uniformity detection, it is made up of with CCD2 lenticular lenses 1, it is characterized in that: lenticular lenses 1 is adjacent to the lower section being placed on the sheet glass scribbling transparent medicinal liquid, the normal of CCD2 axis and sheet glass is placed on the top of sheet glass at an angle, make the stripe pattern passing through the lenticular lenses 1 of sheet glass and transparent medicinal liquid intactly to be photographed by CCD2, in described lenticular lenses 1 grating fringe of marking should parallel, chequered with black and white, width is consistent with spacing and in sharp contrast.
Because the thickness of the sheet glass used all has, the uniformity of the transparent medicinal liquid smeared can be judged qualitatively thereby through the image observing CCD2 shooting；By demarcating, the concrete numerical value on transparent medicinal liquid thickness can be calculated further.
For the ordinary skill in the art, according to the teachings of the present invention, when without departing from principles of the invention with spirit, change, amendment, replacement and modification that embodiment is carried out still fall within protection scope of the present invention.
