Description

Technical Field

[0001] The present application relates to the technical field of fingerprint feature recognition, and in particular to a finger vein live biometric feature recognition and identity security login device. Background Art

[0002] Fingerprints have almost become synonymous with biometric identification due to their lifelong immutability, uniqueness and convenience. However, fingerprint identification also has its limitations. Although everyone's fingerprints are unique, they are not suitable for every scenario. For example, if the fingers of a person who has been doing manual work with both hands for a long time are slightly damaged or have different dry and wet environments or are stained with foreign objects, the fingerprint recognition function will be ineffective. In addition, a special imitation fingerprint film technology has appeared on the market. By copying the fingerprint pattern of the subject, the fingerprint can be copied on a material similar to silicone. Because the copied fingerprint is the same as the subject's fingerprint, it can also be verified by a conventional fingerprint recognition device. As long as the tester puts the imitation film on his fingertips, he can deceive the conventional fingerprint recognition device.

[0003] In addition, most of the commonly used fingerprint recognition devices currently rely on physical contact between the finger and the fingerprint scanner device, and contact use will bring some adverse effects. For example, the force with which the user presses the contact surface will affect the acquired image. If the force is too strong, the acquired fingerprint patterns will overlap and cannot be used; if the force is too weak, the fingerprint patterns will be unclear or too small due to insufficient contact and cannot be used, resulting in low recognition accuracy of the fingerprint recognition system. In addition, the contact collection method will not only cause wear on the contact surface, thereby reducing the performance of the device, but also leave fingerprint traces and bacteria on the contact surface, causing safety hazards and causing people to worry about hygiene. Utility Model Content

[0004] The finger vein live biometric feature recognition and identity security login device proposed in this application is to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, this application adopts the following technical solutions:

[0006] A finger vein live biometric feature recognition and identity security login device comprises a device body, a finger vein recognition panel is fixedly installed on the front end of the device body, an ultrasonic generator is fixedly installed on the back side of the device body, a disinfection mechanism is provided on the upper end of the finger vein recognition panel, a box is fixedly installed on the back of the device body, a cleaning drive mechanism is provided on the inner side of the box, a U-shaped rod is penetrated through the front end of the device body, one end of the U-shaped rod is rotatably connected to a cleaning roller, and the other end of the U-shaped rod is fixedly connected to the cleaning drive mechanism.

[0007] By adopting the above technical solution, when fingerprint recognition is performed, the ultrasonic generator forms a fingerprint image by reflecting the sound wave signal on the fingerprint surface, and no contact is required, so that the contact surface will not be worn to reduce the performance of the equipment. The cleaning drive mechanism drives the cleaning roller to clean the surface of the finger vein recognition panel, and then the disinfection mechanism disinfects the cleaning roller. No fingerprint traces and bacteria will remain on the contact surface, thereby avoiding safety hazards and causing people's concerns about hygiene.

[0008] As a preferred embodiment, the disinfection mechanism comprises a rectangular shell with one end open, an arc-shaped lampshade is fixedly mounted on the inner side of the rectangular shell, and a plurality of equally spaced ultraviolet lamps are fixedly mounted on the inner wall of the arc-shaped lampshade.

[0009] By adopting the above technical solution, the cleaning roller that has finished cleaning retreats into the inner side of the rectangular shell when resetting and approaches the arc lampshade. At this time, multiple ultraviolet lamps distributed at equal intervals disinfect it, further improving the cleaning effect.

[0010] As a preferred embodiment, the cleaning drive mechanism includes a rack, which is fixedly connected to the U-shaped rod, and the inner walls on both sides of the box are rotatably connected to a rotating shaft, and a worm gear is fixedly installed on the middle part of the rotating shaft, and the worm gear is meshingly connected to the rack, and a forward and reverse motor is fixedly installed on the inner wall on the other side of the box, and the output shaft of the forward and reverse motor is fixedly connected to a worm, and the end of the worm is rotatably connected to a fixed seat, and the worm is meshingly connected to the worm gear.

[0011] By adopting the above technical solution, after the forward and reverse motor receives the signal from the controller, it drives the worm to rotate, the worm then drives the worm wheel to rotate, the worm wheel then drives the rack to move, and the rack then moves the U-shaped rod up and down, thereby driving the cleaning roller to clean the surface of the finger vein recognition panel, removing the fingerprint traces and bacteria remaining on the contact surface, avoiding safety hazards and causing people's concerns about hygiene.

[0012] As a preferred embodiment, two through grooves are provided on the surface of the device body, and the two through grooves are symmetrically distributed on both sides of the finger vein recognition panel.

[0013] By adopting the above technical solution, the two through grooves are used for the bifurcated ends of the U-shaped rod to pass through, so as to facilitate its movement along the two sides of the finger vein recognition panel.

[0014] As a preferred embodiment, the end of the U-shaped rod is provided with symmetrically distributed grooves along the inner wall, and a moving block is slidably connected to the inner side of the groove. Both of the moving blocks are rotatably connected to the two ends of the cleaning roller, and a spring is fixedly connected between the moving block and the inner wall of the groove.

[0015] By adopting the above technical solution, the moving block can slide on the inner side of the groove. When the cleaning roller contacts the surface of the finger vein recognition panel, the cleaning roller is subjected to pressure and moves upward a short distance, thereby driving the moving block to move upward and compressing the spring. The elastic potential energy stored in the spring when compressed makes the cleaning roller in close contact with the surface of the finger vein recognition panel, thereby ensuring the cleaning effect of the finger vein recognition panel.

[0016] As a preferred embodiment, an infrared sensor is fixedly embedded on the surface of the finger vein recognition panel, a controller is fixedly installed on the inner wall of the box, the output end of the infrared sensor is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the input end of the forward and reverse motor.

[0017] By adopting the above technical solution, when fingerprint recognition is performed, the infrared sensor detects the hand signal and then transmits the electrical signal to the controller. After the finger is separated from the finger vein recognition panel, the controller starts the forward and reverse motors to perform cleaning work.

[0018] Beneficial effects of this application:

[0019] The finger vein live biometric feature recognition and identity security login device is provided with a device body, a disinfection mechanism and a bottom box. After the forward and reverse motor receives the signal from the controller, it drives the worm to rotate, and the worm then drives the worm wheel to rotate, and the worm wheel then drives the rack to move, and the rack then moves the U-shaped rod up and down, thereby driving the cleaning roller to clean the surface of the finger vein recognition panel, removing the fingerprint traces and bacteria remaining on the contact surface, avoiding safety hazards and causing people's concerns about hygiene.
