Long magnetic strip sensor for banknote authentic identification, banknote detection structure and assembly method

Abstract

The invention discloses a long magnetic strip sensor for banknote authentic identification, a banknote detection structure and an assembly method. Two protrusions are fixedly arranged at the two endsof a support of the long magnetic strip sensor. The free surface of each bulge comprises a platform and a positioning column. The distances between the two positioning columns and the platform on thesame bulge are equal. A long magnetic strip sensor body is attached and fixed to the platform through the backs of the two ends. When the long magnetic strip sensor is installed in a financial machinetool with banknote authentic identification capability, the support of the long magnetic strip sensor can be ensured to be parallel to the transmission bristle wheel in the length direction only by respectively contacting the positioning columns with the outer rings of the two transmission shaft bearings of the transmission shaft. Only the outer side end face of the second protrusion is screwed on the second side wall of the support through screws, the outer side end face of the first protrusion is connected and matched with the first side wall through inserted positioning blocks by arrangingassembling holes and are limited in the circumferential direction, and therefore the situation that the support arches due to the fact that the screws at the two ends are screwed too tightly is prevented.

Description

technical field [0001] The invention relates to the field of financial equipment, in particular to a long magnetic strip sensor for banknote identification, a banknote checking structure and an assembly method. Background technique [0002] With the development of social economy, the circulation of banknotes is also increasing, resulting in more use of various financial instruments to process banknotes. But at the same time, the problem of counterfeit banknotes has also begun to appear, so there are more and more financial instruments with the ability to detect counterfeit banknotes. The previous financial equipment did not have a clear and unified technical index, but mostly adopted industry standards or enterprise standards as the design basis. Beginning in 2018, led by the People's Bank of China, with the participation of many banks and enterprises, clear performance indicators have been put forward for financial equipment, mainly reflected in improving the speed of coun...

Problems solved by technology

And when both ends of the bracket are tightened, it is easy to cause the bracket to be arched and deformed due to overtightening, which will further increase the non-parallel between the long magnetic strip sensor and the driving hair wheel
