Precise counting device and method based on microimaging method

Abstract

The invention discloses a precise counting device based on the microimaging method. The device comprises a paper money conveying system, a paper money positioning mechanism, an image acquisition system and a microimaging system, wherein the paper money conveying system is arranged on a machine frame, the image acquisition system is arrange above the paper money conveying system through a support, the microimaging system is connected with the support through a lifting adjusting mechanism and arranged between the image acquisition system and the paper money conveying system, the paper money positioning system is arranged on the paper money conveying system and used for positioning paper money conveyed by the paper money conveying system within the acquisition range of the image acquisition system, and the paper money conveying system, the paper money positioning mechanism and the image acquisition system are all connected with a control system. The device is mainly used for counting plastic-packaged thousand-based paper money products in different specifications, and effectively solves the problem that in the current paper money production process, paper money is counted in a large-sheet hundred-based mode, cut, bundled in a small-sheet thousand-based mode and plastic-packaged and then no other counting operation is conducted, and therefore potential number safety hazards exist.

Description

technical field [0001] The invention belongs to the technical field of paper counting, and in particular relates to a precision counting device and a counting method based on a microscopic imaging method. Background technique [0002] At present, in addition to mechanical devices for counting paper, non-contact counting methods mainly include electromagnetic wave paper counting, photoelectric paper counting devices, and visual paper counting. [0003] Among them, the principle of electromagnetic wave paper counting is a system that counts the number of layers of a multilayer object using a reflection method and a transmission method. The advantage is that the principle is simple, and it is not affected by paper infolding, paper adhesion, paper side burrs, ambient light, etc. The disadvantage is that it is affected by the electromagnetic wave generation conditions and the thickness of the detected object. [0004] The principle of the photoelectric paper counting device is ...
