Abstract
The utility model provides an ultraviolet-exciting fluorescent ink anti-counterfeiting device comprising an upper sensor and a lower sensor mounted on a rack, wherein either the upper sensor or the lower sensor comprises a box body, and an electronic circuit board and a dustproof lens arranged on the box body; an ultraviolet emitter and a laser receiver are mounted on the same lateral surface of the electronic circuit board, and matched with each other to achieve the detection of fluorescent ink. By mounting the ultraviolet emitters and the laser receivers on the same lateral surface of the electronic circuit boards of the upper sensor and the lower sensor, the anti-counterfeiting device of the utility model is capable of achieving the high capability to trap the altered notes with no signals or poor signals from the fluorescent ink when the notes are counted, for example, the anti-counterfeiting device is capable of conveniently and accurately discriminating the patched notes, in which the safety lines are genuine but the other parts are forged. The anti-counterfeiting device of the utility model has the advantages of simple structure, convenient use, high practicability and accurate detection.
Description
Technical field
The utility model relates to a kind of photoelectric detection system, particularly a kind of ultraviolet ray excited fluorescent ink false proof device that is used to differentiate the Renminbi true and false.
Background technology
Along with China's sustained and rapid development of economy, cash flow flux on the market is increasing, the thing followed is that the fraud activity of Renminbi is also more and more rampant, the quantity of counterfeit money is more and more, kind emerges in an endless stream especially, especially based on the adulterium coin, this has upset China people's the daily life and the order of the market economy to a certain extent.On the current China market circulation maximum be the 5th the cover Renminbi, this cover Renminbi anti-counterfeiting characteristic be go through the cover Renminbi the most complete, it mainly comprises artificial anti-counterfeiting characteristic and machine-readable anti-false feature.And the various counting currency examine equipment on the market all with machine-readable signal as anti-counterfeiting characteristic, but since the uneven performance of the counting currency examine equipment on the market that caused of each company's technical merit very different especially.Though can differentiate for the false most of machines of Renminbi, but be powerless for true other parts for the false most paper money counter of coin of piecing together for those safety lines for some safety lines.
Summary of the invention
The purpose of this utility model is at above-mentioned existing problems and deficiency, provide a kind of being used to finish that fluorescent ink detects and the false distinguishing ability of Renminbi has been had further raising by actinolyte and laser pickoff, and simple in structure, practical ultraviolet ray excited fluorescent ink false proof device.
The technical solution of the utility model is achieved in that
Ultraviolet ray excited fluorescent ink false proof device described in the utility model, comprise rack-mounted upper sensor and lower sensor, described upper sensor and lower sensor respectively include box body, are arranged on electronic circuit board and dustproof eyeglass on the box body, be characterized on the same side of described electronic circuit board actinolyte and laser pickoff being installed, and finish fluorescent ink by being used of described actinolyte and laser pickoff and detect.
In order to ensure obtaining required spectrum, the tip position place that is positioned at actinolyte and laser pickoff in the above-mentioned box body is provided with optical filter.
The utility model is because employing is equipped with actinolyte and laser pickoff on the same side of upper and lower sensor electronics wiring board, and utilize actinolyte and laser pickoff to be used and finish the fluorescent ink detection, adulterium coin to those nonfluorescent oil China ink signals or fluorescent ink dtr signal has the very strong power of catching in a stir-fry like this, be the false coin of piecing together such as those safety lines for true other parts, this device can make things convenient for exactly to be differentiated.The utlity model has simple in structure, easy to use, practical and detect advantages such as accurate.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model upper sensor;
Fig. 3 is the structural representation of the utility model lower sensor.
Embodiment
As shown in Figure 1-Figure 3, ultraviolet ray excited fluorescent ink false proof device described in the utility model, comprise the upper sensor 2 and the lower sensor 3 that are installed on the frame 1, and upper sensor 2 and lower sensor 3 respectively include box body 4, are arranged on electronic circuit board 5 and dustproof eyeglass 6 on the box body 4, actinolyte 7 and laser pickoff 8 wherein are installed on the same side of electronic circuit board 5, and finish fluorescent ink by being used of this actinolyte 7 and laser pickoff 8 and detect.Promptly when banknote passes through this device, actinolyte 7 sends on the fluorescent ink that ultraviolet ray shines banknote, and ultraviolet emission wavelength is 254nm～405nm, and fluorescent ink is through the ultraviolet spectrum that can launch a series of wavelength that excites, the spectrum of these a series of wavelength is received by laser pickoff 8 simultaneously, and the centre wavelength of the light that laser pickoff 8 receives is the pairing wavelength of peak-peak of the spectrum in the visible-range, and through behind the laser pickoff 8, light signal changes into electric signal, then by electronic circuit filtering, amplify, send into single-chip microcomputer after the comparison process, finish the identification and the processing of signal by single-chip microcomputer.In order to ensure obtaining required spectrum, the tip position place that is positioned at actinolyte 7 and laser pickoff 8 in box body 4 is provided with optical filter 9.And the output plug signal of laser pickoff 8 is connected with the socket of electronic circuit board 5, helps the dismounting and the replacing of laser pickoff 8 like this.In addition, optical filter emission in 9 fens optical filter and reception optical filter, and emission optical filter and actinolyte 7 corresponding uses receive optical filter and laser pickoff 8 corresponding uses.As Fig. 2 or shown in Figure 3, box body 4 is provided with slotted eye, and the quantity of slotted eye is corresponding with the quantity of actinolyte 7 and laser pickoff 8 respectively, wherein optical filter 9, actinolyte 7 and laser pickoff 8 all install in the slotted eye of correspondence, and electronic circuit board 5 is fixedlyed connected with box body 4 by screw, dustproof 6 devices of eyeglass are on the surface of box body 4, are used to prevent that dust from entering in the box body 4 and influence the result of use of sensor.
In view of the distribution difference of tow sides fluorescent ink on the banknote, and banknote has positive and negative two kinds of different modes by this device the time, and installation two these devices of cover that in actual applications can symmetry so just can be finished the detection to fluorescent ink more accurately.
The utility model is described by embodiment, but the utility model is not construed as limiting, with reference to description of the present utility model, other variations of the disclosed embodiments, expect easily that as professional person such variation should belong within the utility model claim restricted portion for this area.
