Accompanying drawing explanation
Fig. 1 is the utility model effective UV sensor detecting device schematic diagram.
Fig. 2 is the vertical view of Fig. 1.
In figure, 1 ultraviolet emission light source; 2 optical filters; 3 photoelectric sensors; 4 light-guiding pillars; 5 ultraviolet reflectance sensor cartridges; 6 banknotes; 7 installing plates; 8 mounting holes.
Embodiment
As Figure 1-Figure 2, the utility model effective UV sensor detecting device, mainly comprises: ultraviolet emission light source 1, optical filter 2, photoelectric sensor 3, light-guiding pillar 4, ultraviolet reflectance sensor cartridge 5 etc., and concrete structure is as follows:
Ultraviolet emission light source 1 and photoelectric sensor 3 are placed on the homonymy of banknote 6, photoelectric sensor 3 is two, be arranged at the both sides of ultraviolet emission light source 1 respectively, optical filter 2 is placed in the front end of two photoelectric sensors 3, and light-guiding pillar 4 is placed in the front end of photoelectric sensor 3 and ultraviolet emission light source 1.Installing plate 7 location is arranged in ultraviolet reflectance sensor cartridge 5, and installing plate 7 has three mounting holes 8, photoelectric sensor 3 and ultraviolet emission light source 1 are arranged in mounting hole 8 respectively, make its mounting structure compact and reasonable.
Wherein, place photoelectric sensor 3 respectively in the both sides of ultraviolet emission light source 1 center line, the distance of each photoelectric sensor 3 distance between center line ultraviolet emission light source 1 center line is equal.Optical filter 2 is placed in the front end of each photoelectric sensor 3, ensures to only have UV signal effectively to pass through.The centerline parallel of the center line of light-guiding pillar 4 and ultraviolet emission light source 1, photoelectric sensor 3, light-guiding pillar 4 can be the cylindrical light-guiding pillar of horizontally set.This Ultraviolet sensor pick-up unit can be more than two, detects simultaneously, can detect the ultraviolet reflectance feature in multiple regions of nominal value to the many places ultraviolet feature of nominal value, by many group ultraviolet reflectance set signalling comprehensives, judges the ultraviolet feature of banknote.
During work, the ultraviolet light that ultraviolet emission light source 1 is launched gets to the surface of banknote 6 after light-guiding pillar 4 focuses on, and banknote 6 surface is by the ultraviolet light after reflection after light-guiding pillar 4 focuses on, and mating plate 2 reflects to photoelectric sensor 3 after filtration.If there is ambient light to disturb, ambient light is when through over-light-transferring pole 4, and due to the difference of focus point, the light of different directions incidence will be refracted to other direction by light-guiding pillar 4, photoelectric sensor 3 can not be reflected to, thus ensure photoelectric sensor 3 not by extraneous optical interference.
