Description

Technical Field

[0001] This utility model relates to the field of finger biometric data collection equipment, and in particular to a multi-finger biometric data collection device. Background Technology

[0002] A biometric fingerprint scanner is a special instrument made based on the characteristics of fingerprints. Fingerprints are unique to each person and remain unchanged throughout life. Footprints, palm prints, lip prints, and the patterns on the retina at the back of the pupil also share these characteristics. However, none are as precise as fingerprints; for example, palm prints are easily worn away and age. This characteristic of fingerprints can be used as a form of identification to represent a person.

[0003] However, current traditional fingerprint scanners on the market use a prism and facial recognition sensor technology. The prism is bulky and heavy, resulting in a large product size that is inconvenient for integration into mainstream products. Furthermore, traditional facial recognition sensors are susceptible to humidity, leading to mold growth and blemishes in the captured images, thus affecting their lifespan. Traditional fingerprint scanners also typically use irregularly shaped prisms and side-lit backlighting, resulting in relatively low grayscale contrast and impacting image quality. Moreover, traditional fingerprint scanners can only collect fingerprints from one finger at a time, requiring 10 fingerprint scans. Even 4-4-2 type four-finger scanners require at least 3 scans to collect biometric data from all 10 fingers. This low efficiency leads to staff congestion and increased workload for staff. Additionally, traditional fingerprint scanners only collect fingerprint features and lack facial recognition capabilities, limiting their functionality and application areas. Utility Model Content

[0004] The main objective of this invention is to propose a multi-finger biometric fingerprint scanner, aiming to solve the problem that existing fingerprint scanners can only collect fingerprints from one finger at a time, requiring 10 fingerprint scans to complete the collection of biometric features from all 10 fingers. This is inefficient, easily leading to backlog and delays for personnel on-site, and increasing the workload for relevant staff. Furthermore, traditional fingerprint scanners can only collect fingerprint features and lack facial image capture capabilities, resulting in limited functionality and application areas.

[0005] To achieve the above objectives, the present invention proposes a multi-finger biometric identification collector, comprising a housing, a four-finger fingerprint collector, and a thumb fingerprint collector. One four-finger fingerprint collector is provided, embedded in the upper wall of the housing. Two thumb fingerprint collectors are provided, respectively embedded on both sides of the front wall of the housing, and respectively located outside the four-finger fingerprint collector. The four-finger fingerprint collector includes a bottom shell, a PCB board, a substrate backlight board, a glass substrate, a TFT sensor, an imaging substrate, a surface contact panel, and a top cover. The PCB board, substrate backlight board, glass substrate, TFT sensor, imaging substrate, and surface contact panel are stacked sequentially from bottom to top within the bottom shell. The top cover is closedly installed on the upper end of the bottom shell, and an opening groove is recessed at the upper end of the top cover. The surface contact panel is located at the lower end of the opening groove.

[0006] Furthermore, there are two four-fingerprint collectors. The four-fingerprint collectors are respectively embedded on both sides of the upper wall of the housing, and the thumb fingerprint collectors are embedded side by side in the middle of the front wall of the housing, with each thumb fingerprint collector located between the two four-fingerprint collectors.

[0007] Furthermore, it also includes a column and a human face acquisition sensor. The lower end of the column is detachably and fixedly connected to the rear end of the upper wall of the housing, and the human face acquisition sensor is disposed at the upper end of the column.

[0008] Furthermore, the rear end of the upper wall of the housing is recessed with a plug groove that is adapted to the column, and the lower end of the column is detachably embedded in the plug groove.

[0009] Furthermore, a male connector is protruding from the lower end wall of the column, and a female connector is recessed at the bottom of the insertion groove. The male connector is detachably embedded in the female connector, and the male connector is electrically connected to the female connector.

[0010] Furthermore, it also includes a short shaft, the upper end of which is provided with a universal ball joint, which is rotatably connected to the lower end wall of the human face acquisition sensor.

[0011] Furthermore, it also includes status indicator lights, which are respectively embedded in the upper wall of the upper cover along the circumferential direction.

[0012] The technical solution of this utility model has the following beneficial effects: Through layered synthesis and the structural design of the substrate backlight plate, the fingerprint scanner is lightweight, energy-efficient, and highly resistant to interference, while possessing high-quality biometric collection characteristics even in strong light environments. Furthermore, by employing a planar backlight and planar acquisition design, this utility model achieves a large sensing area, no distortion, and 1:1 image reproduction, resulting in clearer 16-bit grayscale acquisition and thus high-quality biometric collection. The lightweight yet robust design of this utility model facilitates integration with the widespread use of artificial intelligence, AI cloud terminals, and integrated self-service devices. Even when used on a desktop, it saves space, making integrated service counters in enterprises and government agencies more convenient. Simultaneously, this utility model integrates a facial image sensor, enabling biometric collection of headshots and faces. This multi-functional integration broadens the product's application scope. Furthermore, the feature of this invention, which can simultaneously collect biometric data from multiple fingers, greatly improves the efficiency of biometric data collection, enhances the efficiency of entry and exit registration, review, and customs clearance, and also improves the work efficiency of other units that need to collect biometric data. It solves the problem of on-site personnel backlog and delays, and also greatly reduces the workload of staff. Attached Figure Description

One four-finger fingerprint collector 102 is provided, embedded in the upper wall of the housing 101. Two thumb fingerprint collectors 103 are provided, respectively embedded on both sides of the front wall of the housing 101, and located outside the four-finger fingerprint collector 102. The four-finger fingerprint collector 102 includes a bottom shell 1021, a PCB board 1022, a substrate backlight board 1023, a glass substrate 1024, a TFT sensor 1025, an imaging substrate 1026, a surface contact panel 1027, and a top cover 1028. The PCB board 1022, substrate backlight board 1023, glass substrate 1024, and TFT sensor 1025 are also included. Sensor 1025, imaging substrate 1026, and surface contact panel 1027 are stacked sequentially from bottom to top inside the bottom shell 1021. The top cover 1028 is closedly covered on the upper end of the bottom shell 1021. An opening groove 10281 is recessed at the upper end of the top cover 1028. The surface contact panel 1027 is located at the lower end of the opening groove 10281. In actual use, the left or right palm can be placed on the four-finger fingerprint scanner, and the thumb can be placed on the thumb fingerprint scanner. This allows for the simultaneous collection of biometric features of the five fingers of the left hand or the five fingers of the right hand, greatly improving the efficiency of biometric feature collection, improving the efficiency of entry and exit registration, review, and customs clearance, and also improving the work efficiency of other units that need to collect personnel biometric features. This solves the problem of on-site personnel backlog and congestion, and also greatly reduces the workload of staff.

[0024] Specifically, it also includes a column 104 and a human face acquisition sensor 105. The lower end of the column 104 is detachably and fixedly connected to the rear end of the upper wall of the housing 101. The human face acquisition sensor 105 is located at the upper end of the column 104. It can realize the biometric acquisition of head and face through the human face acquisition sensor, making the application field of the product more extensive.

[0025] Specifically, the rear end of the upper wall of the housing 101 is recessed with a plug groove 1011 that is compatible with the column 104. The lower end of the column 104 is detachably embedded in the plug groove 1011, so that the column can be easily disassembled when not in use.

[0026] Specifically, a male connector 1041 is protruding from the lower end wall of the column 104, and a female connector (not shown) is recessed at the bottom of the insertion groove 1011. The male connector 1041 is detachably embedded in the female connector, and the male connector 1041 is electrically connected to the female connector.

[0027] Specifically, it also includes a short axis 106, the upper end of which is provided with a universal ball joint (not shown). The universal ball joint is rotatably connected to the lower end wall of the portrait acquisition sensor 105, so that the portrait acquisition sensor can be flexibly rotated to adjust the shooting angle, making it highly adaptable.

[0028] Specifically, it also includes status indicator lights 107, which are embedded in the upper wall of the upper cover 1028 along the circumferential direction.

[0029] Specifically, the surface of the surface contact panel has an H9 level of scratch resistance and pressure resistance. Example

[0030] The difference between this embodiment and Embodiment 1 is that:

[0031] like Figure 4 As shown, there are two four-fingerprint collectors 102. The four-fingerprint collectors 102 are respectively embedded on both sides of the upper end wall of the housing 101, and the thumb fingerprint collectors 102 are embedded side by side in the middle of the front end wall of the housing 101. The thumb fingerprint collectors 103 are located between the two four-fingerprint collectors 102. By placing the four fingers of the left and right hands on the four-fingerprint collectors at the same time, and placing the thumbs on the thumb fingerprint collectors, the biometrics of 10 fingers can be collected at the same time. This greatly improves the efficiency of biometrics collection, improves the efficiency of entry and exit registration, review, and customs clearance, and also improves the work efficiency of other units that need to collect personnel biometrics. It solves the problem of on-site personnel backlog and congestion, and also greatly reduces the workload of staff.

[0032] Specifically, the working principle and process of this utility model are as follows:

[0033] This invention, through layered synthesis and a substrate backlight design, makes the fingerprint scanner lightweight, energy-efficient, and highly resistant to interference, while also providing high-quality biometric data collection in strong lighting environments. Furthermore, by employing a planar backlight and planar acquisition design, it achieves a large sensing area, distortion-free operation, and 1:1 image reproduction, resulting in clearer 16-bit grayscale acquisition and high-quality biometric data collection. Its slim yet robust design facilitates integration with widely used artificial intelligence, AI cloud terminals, and integrated self-service devices, saving space even on desktops and enhancing convenience for enterprise and government service counters. Additionally, it integrates a facial image sensor, enabling the collection of both headshots and faces. This multi-functional integration broadens the product's application scope.
