Embodiment

[0025] refer to Figure 1-5 , a reflective finger vein authentication device, comprising a device housing 1, the device housing 1 is slidably sleeved with a baffle 3 through a placement groove 2, and a plurality of return springs 4 are fixedly connected between the baffle 3 and the inner side wall of the placement groove 2, and placed The inner bottom wall of the groove 2 is provided with an installation groove 5, and the inner wall of the installation groove 5 is glued with a glass plate 10. There is a certain distance between the glass plate 10 and the placement groove 2, so as to avoid direct contact of the fingers with the glass plate 10, and avoid fingers. Dust, water, and grease adhere to the glass plate 10. A number of infrared light sources 9 are glued to the side wall of the installation groove 5. A fixed rod 6 is glued to the side wall of the installation groove 5. The fixed rod 6 is connected with a mounting seat 7 through a bearing penetrating and rotating. The upp...

Abstract

The invention discloses a reflective finger vein authentication device, comprising a device casing, a baffle is slidably sleeved on the device casing through a placement slot, and a plurality of return springs are fixedly connected between the baffle and the inner side wall of the placement slot, so The inner bottom wall of the placement slot is provided with an installation slot, the inner side wall of the installation slot is glued with a glass plate, the side wall of the installation slot is glued with a number of infrared light sources, the side wall of the installation slot is glued with a fixing rod, and the fixing rod passes through The bearing is rotatably connected with a mounting seat, the upper surface of the mounting seat is provided with an infrared sensitive micro camera, the two opposite side walls of the mounting seat are glued with metal blocks, and a pump suction device is arranged in the device shell, so the The device casing is provided with an automatic adjustment device. The advantages are that the device in the present invention can effectively avoid the influence of dust on the authentication accuracy, and at the same time can be automatically adjusted according to the finger offset, which improves the authentication speed when the finger is offset.

Description

technical field [0001] The invention relates to the technical field of biometric identification, in particular to a reflective finger vein authentication device. Background technique [0002] With the continuous development of science and technology, biometric technology is also constantly developing, including fingerprint recognition, iris recognition, vein recognition, etc. On the one hand, the fingerprint recognition technology is more common among them, and the fingerprint recognition technology has certain disadvantages, such as dust or water on the fingertips during recognition, resulting in recognition failure, and as the age increases, the fingerprint gradually wears out, which may also lead to Authentication fails, and fingerprint authentication is easy to be stolen. Therefore, vein recognition is gradually replacing traditional fingerprint recognition with its recognition accuracy and security. [0003] In the prior art, dust is easy to accumulate on the glass pla...
