Abstract
The utility model relates to an extinction detecting device for recognizing a hue of a laser printed matter. The extinction detecting device is characterized by comprising an LED light source, a condensing lens, a diffusing hemisphere, a diffusing ball, an optical collecting and detecting device and a conveying device, wherein a printed matter to be detected is paved on the conveying device, and passes through the bottom of the diffusing hemisphere; an optical path passes through the LED light source, the printed matter to be detected and the condensing lens in sequence, reaches an entrance port of the diffusing ball, is output from an exit port of the diffusing ball, and is collected by the optical collecting and detecting device. The diffusing hemisphere provides a diffused light environment isolated from external light, and facilitates providing the pattern of the printed matter to be detected for the diffusing ball completely and clearly for extinction on laser interference light, and eventually obtaining the complete and clear pattern of the printed matter to be detected; the extinction detecting device can provide the laser printed matter with continuous, clear and high-efficient quantitative quality detection for laser extinction, and greatly improves the detection efficiency of the laser printed matter.
Description
Technical field
The utility model relates to printing or optical detection apparatus, is a kind of delustring pick-up unit of identifying laser printing product form and aspect specifically.
Background technology
At present aspect packing paper use material, conventionally with laser paper printing, show and dazzle color effect, in this class paper, contained iridescence effect is observed and can be reflected different rainbow radiance in different angles, on this paper, print and there is good visual performance power, give pleasing sensation.But this radium-shine color effect of dazzling detects and has brought great difficulty to the form and aspect of printing just, because this laser paper is observed background color under Different Light, has larger difference, and this difference, under the interference of laser light, is easy to cause the product colour cast of printing.Also just skilled labor is by conversion paper angle for existing detection means, and searching laser light disturbs less position class to distinguish, subjectivity is too high, and accurate not, the original hue value of color cannot truly be detected.It is also helpless that existing aberration detecting instrument both domestic and external has the form and aspect detection of laser light effect for this class, wants to accomplish accurate detection, can only carry out delustring processing to laser light effect.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of delustring pick-up unit that can objective identification laser printing product form and aspect.
The delustring pick-up unit of described identification laser printing product form and aspect, it is characterized in that: comprise LED light source, condenser, diffusion hemisphere, globe of diffusion, optically detecting and checkout equipment and conveyer, described condenser, described LED light source, the entrance port of globe of diffusion and printed matter to be measured are all isolated with ambient light in described diffusion hemisphere, described printed matter to be measured is laid on described conveyer by the bottom of described diffusion hemisphere, described condenser is in the entrance port of described globe of diffusion and the centre position between printed matter to be measured, and printed matter sampling spot to be measured, condenser central point, the entrance port central point of globe of diffusion point-blank, make light path pass through successively described LED light source, printed matter to be measured, condenser arrives the entrance port of globe of diffusion, then from globe of diffusion exit portal, export, by optically detecting and checkout equipment, gathered.
An embodiment, the inwall of described diffusion hemisphere is coated with magnesium oxide diffusing layer, for diffusion hemisphere inside being provided to diffused light environment and isolating with ambient light.
As prioritization scheme, in the light path between described globe of diffusion exit portal and described optically detecting and checkout equipment, be provided with scattered grating.
As prioritization scheme, the pick-up transducers of described optically detecting and checkout equipment is line array CCD.
The utility model is used the equipment of comparatively simplifying and the form and aspect that convenient, objective means have realized laser printing product to detect, in diffusion hemisphere, use simple condenser to project globe of diffusion, by after the laser light delustring containing, from arbitrary position sampling analysis of globe of diffusion, all can obtain the pattern sample delustring, for printing qualities objective, evaluation laser printing product that quantize provide easy, feasible instrument.And diffusion hemisphere provides a diffused light environment of isolating with ambient light, is conducive to printed matter pattern to be measured clearly to offer globe of diffusion to radium-shine interference light delustring comprehensively, finally obtains comprehensively printed matter pattern to be measured clearly.This scheme can provide continuous, clear, efficient radium-shine delustring quantitative quality testing to laser printing product, has greatly improved the detection efficiency of laser printing product.

In figure: 1-globe of diffusion, 2-entrance port, 3-globe of diffusion exit portal, 4-scattered grating, 5-optically detecting and checkout equipment, 6-diffusion hemisphere, 7-condenser, 8-LED light source, 9-printed matter to be measured, 10-conveyer.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated: as shown in fig. 1, the delustring pick-up unit of described identification laser printing product form and aspect, comprise LED light source 8, condenser 7, diffusion hemisphere 6, globe of diffusion 1, optically detecting and checkout equipment 5 and conveyer 10, described condenser 7, described LED light source 8, the entrance port 2 of globe of diffusion 1 and printed matter to be measured 9 are all isolated with ambient light in described diffusion hemisphere 6, described printed matter to be measured 9 is laid on described conveyer 10 by the bottom of described diffusion hemisphere 6, the inwall of described diffusion hemisphere 6 is coated with magnesium oxide diffusing layer, for diffusion hemisphere inside is provided diffused light environment and is isolated with ambient light.Light path arrives the entrance port 2 of globe of diffusion 1 successively through described LED light source 8, printed matter to be measured 9, condenser 7, then from 3 outputs of globe of diffusion exit portal, by optically detecting and checkout equipment 5, gathered.In light path between described globe of diffusion exit portal 3 and described optically detecting and checkout equipment 5, be provided with scattered grating 4.The pick-up transducers of described optically detecting and checkout equipment 5 is line array CCD.
Described condenser 7 is in the entrance port 2 of described globe of diffusion 1 and the centre position between printed matter to be measured 9, and entrance port 2 central points of printed matter 9 sampling spots to be measured, condenser 7 central points, globe of diffusion 1 point-blank, make the transmission focusing point of condenser 7 be positioned at the entrance port 2 of globe of diffusion 1.
Before detection, first adjust the position of LED light source and condenser, make the projection focus of condenser be positioned at the entrance port of globe of diffusion, the light of LED light source provides a diffused light environment being isolated from the outside in diffusion hemisphere, simultaneously, LED light source mainly concentrates on printed matter surface to be measured by projection light, suitably illumination and the projection light of intensity make printed matter to be measured can pass through continuously projection area, condenser reduces the pattern light of reflection in globe of diffusion entrance port, process integration diffuse effect in globe of diffusion, after the radium-shine interference light effect of cancellation, arbitrary position output from globe of diffusion, after scattered grating, by line array CCD, gathered, become digital information, be convenient to analyze pattern effect and the objective appraisal result that obtains a colour killing, described optically detecting and checkout equipment 5 complete the identification of complete pattern and control test by positioning mark set on printed matter to be measured.
