Description

Technical Field

[0001] This application relates to the field of biometric recognition technology, and in particular to an intelligent linkage biometric acquisition device. Background Technology

[0002] In some application scenarios, the rapid and accurate acquisition of various biometric information, including palm prints, is crucial. Clear palm print images are key to accurate comparison and recognition, and this is especially important to address issues such as dry skin and unclear lines on the hands of the person being photographed.

[0003] Existing technologies include a skin humidification process before palm print acquisition, which typically involves spraying water mist onto the palm using a misting nozzle to temporarily moisten the skin surface, thereby making the palm print grooves more prominent and improving image contrast and quality. However, when the above-mentioned atomization humidification technology is applied in practice, especially in high-intensity and continuous acquisition work, while atomization humidification improves the quality of a single acquisition image, it inevitably leads to liquid residue and contamination on the acquisition panel.

[0004] When a wet palm is pressed onto the collection panel, it leaves a mixture of liquid stains containing skin flakes, oil, and potentially biological samples. If this is not cleaned thoroughly in time, the palm of the next person being collected will come into direct contact with this stain, causing smudges, reflections, or texture distortion on their palm print image. This severely affects the usability of the image, making the original intention of humidification to improve image quality counterproductive.

[0005] Currently, the treatment of these residues mainly relies on manual wiping at regular intervals, which frequently interrupts the process during high-intensity collection operations, seriously affecting overall efficiency.

[0006] In other words, existing technologies have the following technical problems: ordinary biometric acquisition devices are prone to contamination of the acquisition panel when collecting palm prints due to the use of wet hands. Therefore, an intelligent linkage biometric acquisition device is proposed to address the above problems. Summary of the Invention

[0013] Furthermore, a screw is rotatably connected to the groove of the panel support base, the screw passes through the movable base and is threadedly engaged with the movable base; A servo motor is fixedly installed on the side wall of the cabinet. The servo motor is connected to the screw through a linkage component and is used to provide power for the rotation of the screw. The servo motor is connected to the self-disinfection component to drive the panel cleaning component and the self-disinfection component to work in sync.

[0014] Furthermore, a horizontal tube is fixedly connected to the connecting frame, and several nozzles are installed on the horizontal tube.

This improves operational efficiency and reliability in high-intensity continuous acquisition scenarios. Furthermore, this application integrates multiple biometric acquisition functions such as height, weight, iris, and facial features, making it particularly suitable for fixed workstations used for one-stop, standardized information collection from users.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0023] Please see Figure 1 and Figure 2 As shown, an intelligent linkage biometric acquisition device includes: Feature acquisition component 3, with a support base 1 fixedly connected to its bottom; The support base 1 is provided with a collection area 101 and a measurement area 102. A weighing device 2 is fixedly installed in the measurement area 102 for collecting the weight data of the object being collected.

[0024] A palmprint acquisition component 4 is fixedly connected to one side of the support base 1. The palmprint acquisition component 4 is located on one side of the acquisition area 101 and is used to acquire the palmprint image of the subject. The palmprint acquisition component 4 is also equipped with a spray structure 10, which is used to spray atomized liquid onto the palm before palmprint acquisition to moisten the skin and improve the quality of palmprint image acquisition.

[0025] A panel cleaning component 6 is installed on the collection panel 403 of the palm print collection component 4. The panel cleaning component 6 is used to automatically scrape off the residual liquid and dirt on the collection panel 403 after each palm print collection. The panel cleaning component 6 is connected to the self-disinfection component 8 and is used to spray disinfection and scrape dry the collection panel 403 in conjunction.

[0026] This application presents a comprehensive technical solution that combines a palmprint acquisition component 4, a spray structure 10, a panel cleaning component 6, and a self-disinfecting component 8. This solution can automatically and sequentially complete a series of operations, including palm humidification, image acquisition, disinfectant spraying, and drying, during a single palmprint acquisition process. This ensures that each acquisition is performed on a clean and dry panel, guaranteeing the stability of image quality and the hygiene and safety of the acquisition process. Consequently, it improves the efficiency and reliability of operations in high-intensity continuous acquisition scenarios. Furthermore, this application integrates multiple biometric acquisition functions, such as height, weight, iris, and facial features, making it particularly suitable for fixed workstations that provide one-stop, standardized information collection for users.

[0027] In a preferred embodiment of this application, see [reference] Figure 1 As shown, the feature acquisition component 3 includes an indicator display screen 301, an iris scanner 302, a camera 303, and a height scanner 304.

[0028] An iris collector 302 is fixedly installed on the side wall of the feature acquisition component 3 to acquire the iris image of the subject's eyes. A height collector 304 is fixedly connected to the upper end of the feature acquisition component 3. The height collector 304 is located above the weighing device 2 and is used to measure the height data of the subject.

[0029] A camera 303 is also fixedly installed on one side of the feature acquisition component 3 for acquiring facial image information of the subject. An indicator display screen 301 is fixedly installed on the side wall of the feature acquisition component 3 for displaying operation instructions, acquisition status and feedback information. An operation display screen 305 is also fixedly installed on the other side of the feature acquisition component 3 for relevant personnel to perform auxiliary operations when the subject is acquiring information.

[0030] By integrating multiple biometric acquisition modules into one, the above technical solution can achieve synchronous or rapid sequential acquisition of information such as height, weight, palm print, iris, and facial features, thereby constructing a complete individual biometric database. This makes the information acquisition process efficient and centralized, reducing equipment footprint and operational complexity.

[0031] In one specific embodiment of this application, see [reference]. Figure 2 and Figure 3 As shown, the palmprint acquisition component 4 includes a cabinet 401, a panel support base 402, and an acquisition panel 403.

[0032] A panel support base 402 is fixedly connected to the upper end of the cabinet 401. A collection panel 403 is fixedly connected to the upper surface of the panel support base 402 for placing the object to be collected and fitting the palm. A palm print image sensor is integrated below or inside the panel support base 402.

[0033] A groove is provided on one side of the panel support 402, and an atomizing nozzle 5 is installed in the groove of the panel support 402 to atomize the liquid and spray it onto the palm placed on the collection panel 403.

[0034] As a preferred technical solution, please refer to Figure 4 As shown, the spray structure 10 includes a water tank 1001 and a delivery pump 1002. The water tank 1001 is also fixedly connected to the inner cavity of the cabinet 401. The delivery pump 1002 is fixedly installed on the upper surface of the water tank 1001. One end of the connecting hose 1003 is fixedly connected to the output end of the delivery pump 1002. The other end of the connecting hose 1003 is connected to the atomizing nozzle 5, forming a passage for delivering liquid from the water tank 1001 to the atomizing nozzle 5.

[0035] The input end of the delivery pump 1002 extends into the inner cavity of the water tank 1001, which is filled with purified water or special atomizing liquid for humidification.

[0036] Furthermore, a sensor 501 is fixedly installed on the side of the atomizing nozzle 5. The sensor 501 is electrically connected to the delivery pump 1002 through the control system of the equipment to realize linkage control of spray start and stop. It is used to automatically start the delivery pump 1002 to spray humidification after sensing that the palm is placed on the collection panel 403, and automatically stop after a preset time.

[0037] In a preferred embodiment of this application, see [reference] Figure 5 and Figure 6 As shown, the panel cleaning assembly 6 includes a movable plate 601, a connecting bracket 603, and a silicone scraper 604.

[0038] The panel support base 402 has grooves on both sides, and sliding grooves are provided in the grooves on both sides of the panel support base 402. Moving plates 601 are slidably connected in the sliding grooves on both sides of the panel support base 402. A crossbar 602 is fixedly connected between the two moving plates 601. A connecting frame 603 is fixedly connected to the crossbar 602. A silicone scraper 604 is fixedly connected to the connecting frame 603 for scraping off liquids and dirt on the surface of the collection panel 403 when it moves close to the surface.

[0039] Further, see Figure 6As shown, a guide rail 607 is also fixedly connected in the groove of the panel support 402. A movable seat 608 is slidably connected on the guide rail 607. A one-way lifting unit is provided at the movable seat 608 to drive the silicone scraper 604 to stick to the panel when moving in one direction and lift away from the panel when moving in the opposite direction.

[0040] The unidirectional lifting unit includes a guide rod 609, a rotating seat 610, a contact wheel 613, and a raised contact portion 614. The guide rod 609 passes through the movable seat 608 and slides between them. The upper end of the guide rod 609 is fixedly connected to the bottom surface of the movable plate 601. One end of the spring 615 is fixedly connected to the bottom surface of the movable plate 601, and the other end of the spring 615 is fixedly connected to the upper surface of the movable seat 608. This provides a downward pressing force for the movable plate 601 and the silicone scraper 604 and allows them to move in the vertical direction.

[0041] Furthermore, see Figure 6 and Figure 7 As shown, a rotating seat 610 is rotatably connected to the lower end of the guide rod 609. A magnetic side plate 611 is fixedly connected to one side of the rotating seat 610. A leg 612 is fixedly connected to the lower end of the rotating seat 610. A contact wheel 613 is rotatably connected to the lower end of the leg 612.

[0042] A raised contact portion 614 is fixedly connected in the groove of the panel support base 402, which is used to force the foot 612 and the rotating base 610 to deflect when the contact wheel 613 rolls over it.

[0043] Through the above technical solutions, such as Figure 6 The diagram shows the perspective. When the movable seat 608 moves to the left, the magnetic side plate 611 is located to the left of the guide rod 609. At this time, the magnetic side plate 611 cannot contact the side wall of the movable seat 608 to limit the rotation of the rotating seat 610. After the contact wheel 613 contacts the protruding contact part 614, it is deflected and cannot overcome the pressure of the spring 615 to make the guide rod 609 rise, thereby making the movable plate 601 in a downward state. This causes the bottom edge of the silicone scraper 604 to stick to the upper surface of the collection panel 403, forming an effective scraping state.

[0044] like Figure 7 From the perspective shown, when the movable seat 608 moves to the leftmost end, the contact wheel 613 separates from the raised contact portion 614. Under the pressure of the spring 615, the silicone scraper 604 continues to press down. Then, when the movable seat 608 moves to the right, as... Figure 8From the perspective shown, since the magnetic side plate 611 is located on the left side of the guide rod 609, when the contact wheel 613 contacts the protruding contact part 614, the stand 612 will be lifted up and drive the rotating seat 610 to rotate clockwise until the magnetic side plate 611 is attracted to the right side of the moving seat 608, thus preventing the rotating seat 610 from continuing to rotate. At this time, the contact wheel 613 continues to roll uphill along the protruding contact part 614 to play a lifting role, causing the guide rod 609 to be lifted and moved upward, thereby driving the moving plate 601, the connecting frame 603, and the silicone scraper 604 to move upward as a whole, so that the blade of the silicone scraper 604 is lifted away from the surface of the acquisition panel 403.

[0045] In summary, the panel cleaning component 6, through the setting of the unidirectional lifting unit, enables the silicone scraper 604 to scrape in one direction and automatically lifts away from the panel when resetting, thus achieving unidirectional scraping and pushing the dirt to one side, thereby avoiding bringing the dirt back or smearing it back and forth, facilitating centralized collection and treatment, and avoiding secondary pollution.

[0046] Preferably, see Figure 5 As shown, a collection tank 404 is also provided on one side of the cabinet 401. The inner cavity of the collection tank 404 is filled with absorbent cotton. The collection tank 404 is located below the end point of the one-way scraping path of the silicone scraper 604 and is used to receive and store the mixed liquid and dirt scraped off from the collection panel 403.

[0047] As a preferred technical solution, a screw 616 is rotatably connected in the groove of the panel support 402. The screw 616 passes through the movable seat 608 and is threadedly engaged with the movable seat 608, which is used to convert the rotational motion of the screw 616 into the linear reciprocating motion of the movable seat 608 along its axial direction.

[0048] A servo motor 7 is fixedly installed on the side wall of the cabinet 401. The servo motor 7 is connected to the screw 616 via the linkage component 9 and is used to provide power for the rotation of the screw 616.

[0049] The servo motor 7 is connected to the self-disinfection component 8 and is used to drive the panel cleaning component 6 and the self-disinfection component 8 to synchronize. With this technical solution, when the servo motor 7 is started, it can drive the linkage component 9 to rotate, thereby driving the screw 616 to rotate and causing the moving seat 608 to move linearly along the guide rail 607. Then, the silicone scraper 604 is driven by the one-way lifting unit to perform scraping or lifting actions.

[0050] Specifically, see Figure 10 As shown, the linkage component 9 includes a protective shell 901, a first transmission rod 902, a second transmission rod 903, a rotating horizontal shaft 905, and a third transmission rod 907.

[0051] The protective shell 901 is fixedly installed on the side wall of the cabinet 401. A first transmission rod 902 is rotatably connected in the inner cavity of the protective shell 901. The first transmission rod 902 is connected to the end of the output shaft of the servo motor 7. A second transmission rod 903 and a rotating horizontal shaft 905 are also rotatably connected in the inner cavity of the protective shell 901. The first transmission rod 902 and the second transmission rod 903 are connected by a first bevel gear set 904. The second transmission rod 903 and the rotating horizontal shaft 905 are connected by a second bevel gear set 906.

[0052] Both sides of the protective shell 901 are rotatably connected to a third transmission rod 907. The third transmission rod 907 is fixedly connected to one end of the screw 616. The third transmission rod 907 is connected to the rotating horizontal shaft 905 through a third bevel gear set 908.

[0053] With this technical solution, when the servo motor 7 is running, it can drive the first transmission rod 902 to rotate, thereby driving the rotating horizontal shaft 905 to rotate through the first bevel gear set 904, the second transmission rod 903, and the second bevel gear set 906. In turn, the third transmission rod 907 on both sides is driven synchronously through the third bevel gear set 908 at both ends, which drives the screws 616 on both sides to rotate synchronously, thereby driving the moving seats 608 on both sides to reciprocate synchronously, in the same direction, and at the same speed.

[0054] As a preferred technical solution, please refer to Figure 4 and Figure 5 As shown, a horizontal tube 605 is also fixedly connected to the connecting frame 603. Several nozzles 606 are installed on the horizontal tube 605. The horizontal tube 605 is connected to the self-disinfection component 8 and is used to receive the disinfectant pumped by the self-disinfection component 8 and spray it onto the surface of the collection panel 403.

[0055] Furthermore, the control logic between the self-disinfection component 8 and the panel cleaning component 6 is as follows: when the silicone scraper 604 is in the scraping state, for example, moving from right to left, the self-disinfection component 8 does not supply disinfectant to the horizontal tube 605. When the silicone scraper 604 is in the raised state and moves back from left to right, the self-disinfection component 8 starts and pumps disinfectant to the horizontal tube 605, so that the nozzle 606 sprays disinfectant onto the surface of the collection panel 403. Through the above control logic, disinfectant can be sprayed onto the surface of the collection panel 403 at the same time when the silicone scraper 604 completes the removal of dirt in one direction and resets. Subsequently, in the next scraping stroke, the silicone scraper 604 will also remove any residual disinfectant, achieving an automated continuous cleaning and disinfection effect of "scraping dirt-disinfecting-scraping dry".

[0056] As a further technical solution, see [link / reference]. Figure 4 and Figure 11 As shown, the self-disinfection component 8 includes a first gear 801, a second gear 802, a lifting platform 804, and a fixed cylinder 806.

[0057] Both the first gear 801 and the second gear 802 are located in the inner cavity of the cabinet 401 and are rotatably connected to the cabinet 401. The first gear 801 is connected to the end of the output shaft of the servo motor 7 to form a power linkage. The first gear 801 and the second gear 802 mesh with each other.

[0058] Through this technical solution, the servo motor 7 can drive the first gear 801 to rotate, thereby driving the second gear 802 to rotate. Simultaneously, referring to the control logic between the self-disinfection component 8 and the panel cleaning component 6, [further details are needed]. Figure 6 and Figure 11 From the perspective of the servo motor 7, when the silicone scraper 604 moves to the left, the first gear 801 drives the second gear 802 to rotate counterclockwise, causing the lifting platform 804 to move upward. Conversely, when the servo motor 7 drives the silicone scraper 604 to move to the right, the first gear 801 drives the second gear 802 to rotate clockwise, causing the lifting platform 804 to move downward. This achieves mechanical linkage between the up-and-down reciprocating motion of the lifting platform 804 and the left-and-right reciprocating motion of the silicone scraper 604.

[0059] In practical implementation, those skilled in the art can adjust the number of teeth of the first gear 801, the number of teeth of the second gear 802, and the lead of the screw 616 to match the scraping stroke of the silicone scraper 604 with the timing of disinfectant spraying. This is conventional existing technology in the field of mechanical design and will not be elaborated further.

[0060] Furthermore, see Figure 11 Fixed guide rods 803 are fixedly installed on both sides of the inner cavity of the cabinet 401. A lifting platform 804 is slidably connected to the fixed guide rods 803 to guide the lifting platform 804 to rise and fall stably only in the vertical direction.

[0061] A round rod 805 is rotatably connected to the eccentric position of the second gear 802. A transverse guide groove is provided on the lifting platform 804. The round rod 805 extends into the guide groove of the lifting platform 804 and slides with the lifting platform 804. Through this technical solution, when the second gear 802 rotates, it can drive the round rod 805 to make a circular motion. Thus, by sliding the round rod 805 in the guide groove of the lifting platform 804, the circular motion is converted into the vertical reciprocating linear motion of the lifting platform 804 along the fixed guide rod 803.

[0062] For specific technical solutions, please refer to Figure 11 and Figure 12As shown, a fixed cylinder 806 is also fixedly connected to the inner cavity of the cabinet 401. A movable piston 807 is slidably connected to the inner cavity of the fixed cylinder 806. One end of a movable rod 808 is fixedly connected to the upper surface of the movable piston 807. The other end of the movable rod 808 is fixedly connected to the lifting platform 804, which is used to convert the up and down movement of the lifting platform 804 into the reciprocating suction movement of the movable piston 807 in the fixed cylinder 806.

[0063] The cabinet 401 has a disinfectant tank 811 fixedly installed inside its cavity. The disinfectant tank 811 is filled with disinfectant liquid, such as 75% medical alcohol, which is convenient for rapid sterilization and easy to evaporate, leaving little residue.

[0064] An input pipe 809 and an output pipe 810 are fixedly connected to the bottom of the inner cavity of the fixed cylinder 806. One end of the input pipe 809 is connected to the disinfectant tank 811, and one end of the output pipe 810 extends to one end of the horizontal pipe 605 and is fixedly connected to and communicates with the horizontal pipe 605, forming a disinfectant delivery passage from the disinfectant tank 811 through the fixed cylinder 806 to the horizontal pipe 605.

[0065] Through the above technical solution, when the lifting platform 804 moves upward, the moving piston 807 can be driven to move upward by the moving rod 808, generating negative pressure in the fixed cylinder 806, thereby drawing the disinfectant in the disinfectant tank 811 into the fixed cylinder 806 through the input pipe 809; when the lifting platform 804 moves downward, it pushes the moving piston 807 to move downward, pushing the disinfectant in the fixed cylinder 806 out through the output pipe 810 and transporting it to the horizontal pipe 605, and finally spraying it out from the nozzle 606, realizing the mechanical linkage and synchronization of the disinfectant spraying action and the silicone scraper 604 reset and lifting action. Specifically, the structure in which the servo motor 7 drives the screw 616 of the panel cleaning component 6 and the first gear 801 of the self-disinfection component 8 simultaneously through the linkage component 9 has the following control logic: when the scraper moves to the left to scrape, the lifting platform 804 moves up and the moving piston 807 is lifted to absorb the disinfectant; when the scraper moves to the right to reset and is in the raised state, the lifting platform moves down and the moving piston 807 is pressed down to spray out the disinfectant, and then the scraper moves to the left again to scrape the disinfectant evenly and dry it.
