Description
Technical field
The invention belongs to the anti-counterfeiting detection technical field, particularly a kind of device that utilizes two light sources to carry out false proof quality testing.
Background technology
Have many materials of anti-counterfeit capability such as banknote, securities, antifalsification paper etc., not only the printing quality of paper own requires very highly, and is added with safe metal wire on paper simultaneously, such as the safety line on the bank-note paper.When detecting these and have anti-counterfeit capability and be added with the antiforge quality of material of safe metal wire, requirement should detect the defective of paper, detect the defective of safety line again, and the surface of safety line is very smooth, similar minute surface, can not produce diffuse reflection, so only under the situation of total reflection, could on image, reflect the actual conditions of safety line.
Be generally and achieve the above object, just need to adopt two cover acquisition systems, a cover is gathered safety line, one cover is gathered paper, again image is spliced analysis after collection is finished, but can produce like this because be spliced image, all the time with real image deviation is arranged, and system is huge, with high costs.
Summary of the invention
Purpose of the present invention is exactly at the deficiencies in the prior art, provide a kind of and can gather reflective texture map picture and paper image simultaneously accurately and fast, carry out simultaneously that paper detects and the counterfeit-prevention quality detection device of reflective material detection, and the application when printing has anti-counterfeit capability and be added with the material of reflective material.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of counterfeit-prevention quality detection device comprises detecting and uses cylinder, the reflective line source first of using, compensate for brightness line source second, and line scan camera; The ejaculation light center face of the ejaculation light center face of line source first and line source second is distributed in the scanning center face both sides of line scan camera respectively, and crossing at outer surface of cylinder with scanning center's face of line scan camera, forms the detection line along the cylinder axial distribution; The ejaculation light center face of line source first and scanning center's face of line scan camera are about the plane symmetry by detection line and cylinder axis.
The metal safety line is a kind of reflective material, can regard minute surface approx as.According to the direct reflection principle, because the ejaculation light center face of line source first and scanning center's face of line scan camera are about the plane symmetry by detection line and cylinder axis, therefore when the metal safety line moves to the detection line position, the light that the line source first is mapped on the metal safety line is just all captured by line scan camera, so just can accurately reflect the actual conditions of metal safety line truly.According to the diffuse reflection principle, because paper is uneven through occurring after printing, the light that the line source first is mapped on the paper will produce diffuse reflection, but wherein has only part luminous energy to be caught by line scan camera simultaneously, and the brightness of image of paper is just not enough like this; In order to obtain high-quality paper image, must improve paper brightness, therefore the scanning center's face with line scan camera is a benchmark, increases a line source second, so just can satisfy the brightness requirement of paper image.
Angle between the ejaculation light center face of line source first and the scanning center's face of line scan camera can be arbitrarily angled.Attractive in appearance for easy for installation and whole detection device, the ejaculation light center face of the ejaculation light center face of line source first and line source second about the scanning center of line scan camera in the face of claiming.For the ease of installing and the debugging scan image, line source first, line source second and line scan camera are fixed on the casing, and it is constant so just to make two light sources and camera remain fixed angle.The position of line scan camera is regulated by governor motion, can be rotated adjusting, parallel adjusting and depth and regulate.Line scan camera is at least 1; When the quantity of line scan camera during greater than 1, they are placed side by side, divide other scanning center's face at grade, and promptly scanning center's face of a plurality of line scan cameras all passes the detection line that is positioned at outer surface of cylinder.
Described counterfeit-prevention quality detection device is to utilize two light reflector imaging techniques, can gather reflective texture map picture and paper image simultaneously accurately and fast, therefore when printing has anti-counterfeit capability and be added with the material of reflective material, described counterfeit-prevention quality detection device is used to detect printing quality, can carry out paper detection and reflective material simultaneously and detect.Described reflective material can be a metal safety line etc.The described material that has anti-counterfeit capability and be added with reflective material can be a banknote, or securities, or antifalsification paper or passport, or I.D., or invoice etc.
With the printing back described material that has anti-counterfeit capability and be added with reflective material to be detected, place detection one by one with on the cylinder.Along with cylinder rotates, described material to be detected is the detection by line scan camera constantly.When moving to the detection line position, the light that the line source first is mapped on the reflective material is all captured by line scan camera, so just can accurately collect the image of reflective material when reflective material (as metal safety line etc.).When paper moved to the detection line position, the light that line source first and line source second are mapped to paper simultaneously made paper have enough brightness, can make the clear paper image that accurately collects of line scan camera.Like this, just can carry out simultaneously that paper detects and reflective material (as the metal safety line etc.) detection, detect the printing quality of detected materials by a cover pick-up unit.
Compared with prior art, the invention has the beneficial effects as follows: can gather reflective texture map picture and paper image simultaneously accurately and fast, can carry out paper detection and reflective material simultaneously and detect, can be used for detecting the printing quality that has anti-counterfeit capability and be added with the material of reflective material.
