[0002] With the rapid development of biometric technologies, fingerprint recognition technology has been widely applied to electronic devices such as smart phones and tablet computers. Existing fingerprint recognition components can be mainly divided into capacitive fingerprint recognition components, optical fingerprint recognition components, thermal fingerprint recognition components, and ultrasonic fingerprint recognition components, etc. Among them, optical fingerprint recognition components have become the most widely used fingerprint recognition components due to factors such as low manufacturing cost and high yield rate. They are widely used in factory attendance check-in by fingerprint recognition devices, and there are often phenomena of queuing for check-in, and even being late due to low fingerprint recognition efficiency. Most of the fingerprint recognition devices in the factory are wall-mounted, that is, the hanging height is about 1.5 m. Even for staff with different heights, when entering fingerprints, the contact points of the fingers on the touch recognition device are at different positions, such as the fingertip, the center of the finger fingerprint, and the front end of the fingerprint center.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0030] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or position relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0031] Please refer to Figure 1-6 As shown, the present invention is a fingerprint recognition module, and the recognition module is an optical module.

[0032] The fingerprint module is used to recognize fingerprints and provide work attendance records for the recognition records.

[0033] It includes a housing 1, which is a conventional-shaped time clock with a display, input buttons, and a fingerprint collection area on its surface. Among them, the housing 1 has an identification cavity 101, and the fingerprint recognition module 4 is installed in the identification cavity 101. The housing 1 is a support frame for the fingerprint collection area, that is, the installation position of the fingerprint recognition module 4, located at a corner of the fingerprint collector. And the housing 1 has a detachable side plate, that is, one side plate of the fingerprint collector is designed to be detachable, and through the disassembly at this position, components such as the fingerprint recognition module 4, the pressure device 8, the adjustment gear 5, the transmission gear set 6, the half gear 7, and the driver 2 can be installed.

[0034] In addition, the fingerprint recognition module 4 has a housing 401. When the fingerprint recognition module 4 is still at the installation angle to be adjusted, the fingerprint recognition module 4 is placed obliquely at the port of the identification cavity 101, and the identification cavity 101 is in an unclosed state.

[0035] One side of the housing 401 is installed with an adjustment gear 5, and the other side is provided with a rotating shaft. The housing 401 is installed on the housing 1 through the adjustment gear 5 and the rotating shaft.

[0036] Specifically:

[0037] The adjustment gear 5 has a main shaft 501, and a pair of pressure plates 502 are installed on the main shaft 501. A pressure device 8 is installed on the housing 401, and the pressure plates 502 are against the pressure device.

[0038] One side of the housing 401 has a stepped hole 404. There are a pair of mounting holes 406 on the stepped surface of the stepped hole 404. The pressure device 8 is fixed in the mounting holes 406. The end of the main shaft 501 is in clearance fit in the thin hole section of the stepped hole 404. The root of the pressure plate 502 is located on the main shaft 501 in the thick hole section of the stepped hole 404. The pressure device 8 includes a threaded rod section 801 and a pressure sensor 802. The mounting hole 406 is a threaded hole, and the threaded rod section 801 is fixed in the threaded hole. The end of the pressure plate 502 is an arc-shaped plate, and the arc-shaped plate is attached to the pressure sensor 802. The arc-shaped plates of the two pressure plates 502 are bent in the opposite direction, and the two pressure plates 502 are against the same side of the two pressure sensors 802. The bottom surface of the housing 401 has a rib 402. The stepped hole 404 is opened on the end surface of the rib 402. There is a through hole 403 on the rib 402 that penetrates the stepped hole 404. That is, when the fingerprint recognition module 4 is pressed, when the pressing center of gravity is on the upper part or the lower part of the rib 402, one of the two pressure sensors 802 will be under pressure, that is, a corresponding electrical signal will be generated, and then the driver 2 or the positioner 3 will be driven according to the electrical signal.

[0039] In addition, one side of the housing 1 has a detachable side plate 102, and there are slots on the side plate 102 for cooperating with the transmission gear set 6, the half gear 7, and the adjustment gear 5.

[0040] Inside the housing 1, a transmission gear set 6 and a half gear 7 are also installed. Among them, the transmission gear set 6 meshes with the adjusting gear 5, that is, the gear for output of the transmission gear set 6 meshes with the adjusting gear 5, and the transmission of the half gear is reduced through the transmission gear set 6.

[0041] The transmission gear set 6 and the half gear 7 are indirectly meshed, that is, the transmission gear set 6 receives the drive of the half gear 7. One end of the rotating shaft on the half gear 7 is linked to a driver 2, and the driver 2 is a micro motor.

[0042] The transmission gear set 6 has a first transmission gear. There is a circle of pin holes 601 on the first transmission gear, and the included angle between two pin holes 601 is 5°. A positioner 3 corresponding to the pin holes 601 is installed on the side plate 102. The positioner 3 is a linear drive mechanism, and the plug pin is installed at the output end of the linear drive mechanism.

[0043] Further, when the half gear 7 rotates one week, the adjusting gear 5 is driven by the transmission gear set 6 to rotate 0.5 - 6°, and preferably the adjusting gear 5 rotates 1° each time.

[0044] Further, the driver 2 and the positioner 3 are driven by the pressure signal of the pressure device 8. The linear drive mechanism and the micro motor work simultaneously. After the micro motor drives the adjusting gear to rotate a certain angle, the positioner 3 locks the transmission gear set 6.

[0045] After a large number of punching changes, the fingerprint recognition module 4 will tend to a middle position to fit the heights of most people and the finger inclination angles when pressing fingers, improving the punching efficiency.

[0046] After determining the angle, a new fingerprint recognition module 4 can be replaced. The area of the fingerprint recognition module 4 completely covers the port of the recognition cavity 101 at the determined inclination angle, and the pressure device 8, the adjusting gear 5, the transmission gear set 6, the half gear 7 and the driver 2 are removed.
