AI Technical Summary

Technical Problem

The existing fingerprint processing devices are mostly horizontal flat plate-shaped. When placing fingers, users need to keep twisting their wrists and pressing the touchpad. This is inconvenient to operate and easily fail to identify due to finger position deviation.

Method used

An automatic finger opening angle fingerprint stimulation prompter is designed, using the cooperation of a rotation recognition mechanism and a control box, and the tooth plate and the mounting ring are pushed through the electric telescopic rod to engage, drive the recognition component to rotate, realize contactless fingerprint collection, and prevent finger contamination through cleaning components and auxiliary mechanisms.

Benefits of technology

It effectively solves the problem of recognition failure caused by finger position offset, improves the accuracy and anti-interference of fingerprint collection, avoids the impact of finger contamination on the identification components, and extends the service life of the equipment.

Abstract

An automatic finger field angle fingerprint stimulation prompter disclosed by the present invention comprises a shell and a base, a rotation identification mechanism is arranged in the shell, the rotation identification mechanism comprises a support rod, a turntable, a mounting gear ring, an identification assembly, a cleaning cotton swab, a toothed plate, a moving plate and an electric telescopic rod, and the mounting gear ring is arranged on one side wall of the turntable. According to the automatic finger field angle fingerprint stimulation prompter, an electric telescopic rod pushes a toothed plate to move, the toothed plate pushes a mounting toothed ring meshed with the toothed plate to drive an identification assembly to rotate in the moving process, and a camera module in the identification assembly focuses and records fingerprints on fingers in the rotating process; the recorded fingerprints are compared and verified with fingerprints in the storage module through the comparison module, and when a verification result passes, the control box controls the computer to carry out confidential operations such as startup and directory expansion through the cooperation of a connecting wire and a connector; and meanwhile, the phenomenon of frequent identification failure caused by finger position deviation is avoided through a rotary dynamic identification mode.
