Currency detection device with adhesive tape detection function

Abstract

The invention discloses a currency detection device with an adhesive tape detection function, which comprises a shell, an image scanning module and an adhesive tape detection module, the image scanning module and the adhesive tape detection module are both arranged in the shell, and the image scanning module and the adhesive tape detection module are adjacently distributed; and the adhesive tape detection module comprises a detection circuit board, a lamp bead, a photodiode and a detection support, the lamp bead and the photodiode are arranged on the detection circuit board, and the detectionsupport covers the adhesive tape detection circuit board. According to the device, pattern scanning detection and adhesive tape detection are integrated. The currency detection device with the adhesive tape detection function has the image scanning function and the adhesive tape detection function, pattern scanning detection and adhesive tape detection are integrated, space is effectively saved, and the adhesive tape detection function is added to an original image sensor; the structure is simple, and the cost can be effectively reduced; and the adhesive tape detection module only has a smallincluded angle for detection, and the stability of adhesive tape detection can be improved.

Description

technical field [0001] The invention relates to the technical field of optical detection equipment, in particular to a banknote verification device with tape detection function. Background technique [0002] Because the counterfeit identification pattern on the existing financial banknote detector mainly relies on optics to scan the special pattern, if there is a scotch tape on the banknote, the scanning of the special image will be biased, so the banknote with the scotch tape on it needs to be taken first recognized. [0003] The existing technology for detecting tapes mainly uses thickness sensors as the main detection method. This method requires high cost and occupies a large volume (please refer to figure 1 ). The second is to use the light sensor (please refer to figure 2 ) to detect the reflective surface of the tape by receiving a large included angle, but because it is difficult to ensure the flatness of passing banknotes during detection, it will change the lar...

Problems solved by technology

[0003] The existing technology for detecting tapes mainly uses thickness sensors as the main detection method. This method requires high cost and occupies a large volume (please refer to figure 1 )

The second is to use the light sensor (please refer to figure 2 ) to detect the reflective surface of the tape by receiving a large included angle, but because it is difficult to ensure the flatness of the banknotes during the detection, it will change the large included angle when receiving, which cannot be guaranteed, and there will be detection accuracy problems

[0004] Due to the problems of high cost, large structure, detection accuracy and inability to integrate existing tape detection technology, this invention project can solve the above problems, effectively reduce cost, reduce structure, increase accuracy and realize integration
