Description
Technical field
The present invention relates to a kind of finishing tool transmission-type reagent liquid medicine painting uniformity detecting method and device, specifically adopt laser light knife to match with CCD, the method and the device that detect spreading upon the uniformity of the transparent liquid medicine painting that viscosity on sheet glass is larger, belong to environmental protection tests method and apparatus field.
Background technology
In environmental protection tests, usually need to test at the scene, in inspection, often use some and be coated with for a long time the sheet glass that wipes liquid reagent. Liquid on these sheet glass generally need to be coated with and wipes and dry in laboratory. What at present, these were also wanted smear is mainly completed by artificial and equipment. The turning round of equipment using is generally circular sponge block, after liquid is dropped on sponge block, sponge block High Rotation Speed simultaneously from top to bottom by liquid medicine painting on sheet glass. Because sponge is turned round in the wearing and tearing in when application, and the viscosity of some liquid uniformity very large so that smear is difficult to ensure. Therefore, in the urgent need to researching and developing a kind of equipment that can automatically detect the uniformity of the larger liquid of automatically smearing of this viscosity, and there is no at present this equipment.
Laser light knife is a kind of LASER Light Source of commonly using in detection, is characterized in that the light sending is a light vertical with laser axis. The refraction of light refers to that when light is slanted through other media from air, the direction of propagation changes, thereby makes the intersection generation deviation of light in different medium. The present invention has applied the refraction principle of light dexterously, has adopted laser light knife and the CCD that can launch straight line to form and can carry out a kind of device automatically detecting to liquid uniformity coefficient.
Summary of the invention
The invention provides a kind of finishing tool transmission-type reagent liquid medicine painting uniformity detecting method and device.
The present invention is achieved by the following technical solutions: a kind of finishing tool transmission-type reagent liquid medicine painting uniformity detecting method, adopt laser light knife and CCD device, it is characterized in that: make the normal of line source that laser light knife sends and sheet glass angled, be incident upon the transparent liquid surface of smearing from the oblique upper of transparent liquid, this light is through transparent liquid and the transparent glass sheet below it, be transmitted on the CCD that is placed at an angle sheet glass below, absorb this image by CCD, observe this image, can carry out liquid that intuitive judgment the smears thickness evenness on radiation direction by observing the linearity of light, this image is machine calculation process as calculated, just can obtain the transparent liquid of smearing and smear uniformly concrete numerical value in laser beam direction: because sheet glass is even thickness, if the liquid of therefore smearing is even, the light transmiting is still straight line, if the liquid of smearing is inhomogeneous, the light transmiting is not straight line, in the method, laser light knife is fixedly connected with CCD, and presses fixed step size moving glass sheet, just can be by calculating the change in location of transmitted ray on CCD, detect with laser light knife light vertical direction on liquid smear the uniformity.
A kind of finishing tool transmission-type reagent liquid medicine painting uniformity detection, formed by laser light knife and CCD, it is characterized in that: laser light knife is placed on the top of the sheet glass that scribbles transparent liquid, and with the normal of sheet glass at an angle, the laser straight line that laser light knife sends can be penetrated on the upper surface of transparent liquid; CCD is placed on the below of sheet glass at an angle, and the axis of CCD is parallel to the axis of laser light knife, and the straight line of the laser light knife transmiting by transparent liquid and sheet glass can be incident upon on CCD camera lens.
Described laser light knife can be fixedly connected with CCD, by fixed step size moving glass sheet, can make the straight line that laser light knife sends move to another side from one side of transparent liquid, to detect the thickness evenness of whole liquid scope.
The usefulness of this invention is to have solved the inhomogeneity quantitative and qualitative analysis test problems of the transparent liquid of smearing at present; Laser beam, by uniform material, comprises transparent liquid and sheet glass, if transparent liquid is all respectively consistent with sheet glass thickness on radiation direction, and the light certainty or the straight line that transmit; If bending has occurred straight line, because the thickness of sheet glass is uniformly, shows undoubtedly that the liquid of smearing is in uneven thickness on radiation direction, and bending amount, can calculate the concrete numerical value of difference on thickness; If the whole area of the liquid of smearing is inswept by fixed step size by many light, can parse the degree of irregularity on the whole area of smearing liquid from the image of CCD.
Brief description of the drawings
Accompanying drawing 1 can detect from the position of the light that transmits the schematic diagram of varied in thickness because of transparent substance variable thickness for optical transmission;
Accompanying drawing 2 is structural representation of the present invention, and wherein 1 is laser light knife, and 2 is CCD;
The schematic diagram that the light that accompanying drawing 3 is laser light knife penetrates, laser light knife is the device that can send a laser beam vertical with laser instrument axial axis.
The ray cast of laser light knife should be at an angle with the normal of the upper surface of transparent liquid as can be seen from Figure 2, the placement of CCD too with the normal of the upper surface of transparent liquid at an angle, and parallel with the axis of laser light knife.
Detailed description of the invention
A kind of finishing tool transmission-type reagent liquid medicine painting uniformity detecting method, adopt laser light knife 1 and CCD2, it is characterized in that: make line source that laser light knife 1 sends and angled being incident upon on the transparent liquid surface of smearing of normal of sheet glass, this light is through transparent liquid and the transparent glass sheet below it, be refracted on the CCD2 being placed at an angle below sheet glass, absorb this image by CCD2, by observing the thickness evenness that can image can intuitively differentiate qualitatively the transparent liquid of smearing in laser beam direction: be even thickness because of sheet glass, if the liquid of therefore smearing is even, the light transmiting is still straight line, if the liquid of smearing is inhomogeneous, the light transmiting is not straight line, this image, through demarcating and computer processing, can detect the numerical value of thickness offset quantitatively, in the method, laser light knife 1 is fixedly connected with CCD2, and presses fixed step size moving glass sheet, just can be by calculating the change in location of transmitted ray on CCD2, detect with laser light knife vertical direction on liquid smear the uniformity.
