Problems solved by technology

The fluorescent detection technology currently used all adopts a reflective structure. The fluorescent tube used needs to be ignited with a voltage of 400V, which has a short life, large volume, and unstable intensity. A single sensor is used to receive signals. , the technical structure has shown great limitations, and the resolution of counterfeiting is low

Embodiment Construction

[0007] see figure 1 The front of the sensor core 2, which is composed of the photoelectric sensor 5 and its corresponding yellow filter 7 and the light emitting devices 1 and 3 and their corresponding purple filters 6 and 8 respectively arranged on both sides of the photosensor 5, is correspondingly provided with a collector Convex mirror 9 ; another set of convex mirror 12 and sensor core 10 with the same structure are correspondingly arranged on the other side of the banknote passage 11 .

[0008] After the visible light is filtered out by the light sources 1 and 3 on both sides of the photoelectric sensor 5 through the purple filters 6 and 8, the transmitted ultraviolet light is converged by the condensing convex mirror 9 and projected on the surface of the banknote 4 to generate a fluorescent reaction. Part of the light generated by the fluorescent reaction passes through the yellow filter 7 to filter out the ultraviolet light and enters the photoelectric sensor 5 above fo...

Abstract

An antiforge optical detector for paper money recognizer is composed of the sensor core consisting of photoelectric sensor and its relative yellow filter and two luminous tubes and their relative purple filters, and the light-gathering convex lens. A same light-gathering connex lens and sensor core is arranged at another side of paper money channel. Its advantages are high efficiency, simple structure, low voltage and small size.

Description

Technical field: [0001] The invention relates to a banknote identification device, in particular to an optical counterfeit detection device of a banknote validator. Background technique: [0002] With the development of society and the enrichment of economic life, people have higher and higher requirements for anti-counterfeiting detection of banknotes. The fluorescent detection technology currently used all adopts a reflective structure. The fluorescent tube used needs to be ignited with a voltage of 400V, which has a short life, large volume, and unstable intensity. A single sensor is used to receive signals. , the technical structure has shown great limitations, and the resolution of counterfeiting is low. Invention content: [0003] The technical problem to be solved by the present invention is to provide an optical counterfeit detection device of banknote identification equipment with high counterfeit detection rate, simple structure and long service life. [0004] ...
