Fingerprint recognition antifouling layer for security check

Abstract

The invention relates to the field of fingerprint recognition, and particularly relates to a fingerprint recognition antifouling layer for security check. The fingerprint recognition antifouling layercomprises a shell, an electromotor, a NO.1 shaft, a connecting rod, a Geneva wheel, a flywheel, a protective film and a recognition window; a cleaning block, a NO.1 biased wheel, a NO.2 biased wheeland a NO.2 shaft are arranged inside the shell; the electromotor is arranged on the right side inside the shell; the NO.1 shaft is positioned on one side, close to the center of the shell, of the electromotor; one end of the connecting rod is connected with the electromotor, and a forward cylindrical rod is arranged on the other end of the connecting rod; the Geneva wheel is connected with the NO.1 shaft, and the Geneva wheel is matched with the cylindrical rod on the connecting rod; the flywheel is connected on the NO.1 shaft; the protective film respectively bypasses through the NO.1 shaft,the NO.1 biased wheel, the NO.2 biased wheel and three NO.2 shafts; the recognition window is arranged right below the middle position of the protective film; according to the equipment, the protective film is covered on the surface of the recognition window, the protective film is driven to move by the Geneva wheel, the cleaning block is used for swiping the protective film, thus being capable ofkeeping the protective film clean after many times of fingerprint recognition, and further maintaining the recognition function of the recognition window.

Description

technical field [0001] The invention relates to the field of fingerprint identification, in particular to a fingerprint identification antifouling layer for security inspection. Background technique [0002] Now many companies will choose fingerprint recognition to allow employees to sign in to and from get off work. On the one hand, it has the attendance function, and on the other hand, it also has the effect of security inspection for some special enterprises. The window often cannot continue to work because of more fingerprints. At this time, the problem can only be solved by wiping the identification window. This solution is very inconvenient. Contents of the invention [0003] In order to solve the above problems, the present invention provides a fingerprint recognition antifouling layer for security inspection. The device covers the protective film on the surface of the identification window, drives the protective film to move through the groove wheel, and wipes the p...
