Description

Technical Field

[0001] This invention relates to the field of information management technology, and more specifically, to an information collection device for improving the accuracy of data collection. Background Technology

[0002] Time and attendance machines, as commonly used information collection devices in enterprise management, mostly record attendance through fingerprint scanning. However, due to the frequent use of fingerprint scanners, fingerprints are easily left on the panel by sweat and other fingerprints. Furthermore, because these machines are often placed outdoors, they become covered in dust, making it difficult or impossible to recognize the fingerprints of other users, thus affecting the quality and efficiency of data collection. In environments where infectious diseases are prevalent, fingerprint attendance can easily lead to cross-contact, especially in large enterprises with thousands of employees requiring the machines to be accessed. The fingerprint-based access method is extremely unhygienic. Alternatively, enterprises with high cleanliness requirements need to minimize cross-contact. Therefore, existing time and attendance machines have many drawbacks.

[0003] In the prior art, patent CN111401254A discloses a high-precision fingerprint recognition device. This device uses a protective mechanism to deliver cleaning fluid through a liquid outlet pipe into a guide tube. The cleaning fluid then seeps into a cleaning cotton tube through a through-hole, thoroughly soaking the cotton tube. A servo motor is then activated, driving an adjustment plate and the cleaning cotton tube to rotate via a shaft. An electric slide rail then moves a horizontal moving plate horizontally via a slider. When the cleaning cotton tube comes into contact with the fingerprint reader, the rotating cotton tube effectively sterilizes and cleans the fingerprint reader. However, in this technical solution, the fingerprint recognition device has only one fingerprint collection surface. After collection, the cleaning cotton tube sterilizes and cleans the fingerprint reader. But during this sterilization and cleaning process, because there is only one collection surface, it is in a clean state and cannot collect fingerprints, significantly reducing collection efficiency. Furthermore, if the collection interval is short, if the surface water on the cleaned collection surface is not completely dried, it will cause inaccurate fingerprint collection results.

Detailed Implementation

[0034] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and by way of embodiments. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0035] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, B exists alone, and A and B exist simultaneously. The term " / and" in this article describes another type of relationship between related objects, indicating that two relationships can exist. For example, A / and B can mean: A exists alone, and A and B exist alone. In addition, the character " / " in this article generally indicates that the related objects before and after it are in an "or" relationship.

[0036] according to Figures 1-11 As shown, an information acquisition device for improving acquisition accuracy includes an identification protective component and a fingerprint recognition component, with the fingerprint recognition component disposed on the identification protective component. The identification protective component includes an outer identification protective shell 1 and an inner identification protective shell 2. The inner identification protective shell 2 is smaller than the outer identification protective shell 1 and is disposed within the outer identification protective shell 1 to provide installation space for the fingerprint recognition component. A circuit board 3 is installed inside the outer identification protective shell 1. The circuit board 3 is electrically connected to the fingerprint recognition component and is used to receive information sent by the fingerprint recognition component and send control signals to the fingerprint recognition component.

[0037] The fingerprint recognition device includes a fingerprint acquisition component, a surface sterilization and cleaning component, and a surface drying component, all of which are mounted on the inner recognition protective shell 2. The fingerprint acquisition component includes a fingerprint acquisition rotation component, a supplementary lighting component, and an image acquisition component, all of which are mounted on the inner recognition protective shell 2. The fingerprint acquisition rotation component includes a fingerprint flip acquisition component and a flipping power component, both of which are mounted on the inner recognition protective shell 2. The fingerprint flip acquisition component includes a fingerprint rotation acquisition surface 4 and a driven shaft 5. The fingerprint rotation acquisition surface 4 is an equilateral pentagonal prism. One end of the driven shaft 5 is vertically fixed to one end face of the fingerprint rotation acquisition surface 4, and the other end is rotatably mounted on the bottom surface of the inner recognition protective shell 2, allowing the fingerprint rotation acquisition surface 4 to rotate circumferentially within the inner recognition protective shell 2 via the driven shaft 5. Furthermore, the side of the fingerprint rotating acquisition surface 4 corresponds to the fingerprint pressing window 6 on the inner identification protective shell 2, so that a person's finger can pass through the fingerprint pressing window 6 and press on the first side of the fingerprint rotating acquisition surface 4, so that the image acquisition device can acquire the image fingerprint. Further, each side of the fingerprint rotating acquisition surface 4 is arc-shaped to increase the pressing contact area between the finger fingerprint and the fingerprint rotating acquisition surface 4.

[0038] The flipping power component includes a first motor 7, a first worm gear 8, a drive shaft 9, and a first worm wheel 10. The first motor 7 is fixedly mounted on the inner identification protective shell 2. The first worm gear 8 is fixedly mounted on the rotating shaft of the first motor 7. One end of the drive shaft 9 passes through the inner identification protective shell 2 and is fixedly connected to the other end of the fingerprint rotating acquisition surface 4. The first worm wheel 10 is fixedly mounted on the other end of the drive shaft 9 and meshes with the first worm gear 8. When the first motor 7 drives the drive shaft 9 to rotate on the inner identification protective shell 2, it will drive the fingerprint rotating acquisition surface 4 to rotate circumferentially. Furthermore, after each fingerprint acquisition, the fingerprint rotating acquisition surface 4 will be driven by the first motor 7 to rotate 72 degrees circumferentially, so that the clean second side of the fingerprint rotating acquisition surface 4 faces the fingerprint pressing window 6, so as to facilitate accurate and efficient fingerprint acquisition for the next person whose fingerprint is to be acquired.

[0039] The supplementary lighting component includes a supplementary lighting support plate 11 and supplementary lighting LEDs 12. The two ends of the supplementary lighting support plate 11 are vertically fixed within the inner identification protective shell 2, such that the longitudinal line of the supplementary lighting support plate 11 is parallel to the axis of the fingerprint rotation acquisition surface 4. Six supplementary lighting LEDs 12 are fixedly connected to the supplementary lighting support plate 11, evenly spaced along the longitudinal direction of the supplementary lighting support plate 11, to illuminate the fingerprint pressing window 6 through the fifth side of the fingerprint rotation acquisition surface 4. The multiple supplementary lighting LEDs 12 distributed longitudinally along the fingerprint rotation acquisition surface 4 can illuminate the fingerprint pressing window 6 at different angles along the axial direction, creating a shadowless lighting effect to improve the clarity of the fingerprint pressed on the first side of the fingerprint rotation acquisition surface 4. This improves the image acquisition component's ability to clearly and efficiently acquire images of the fingerprint on the first side of the fingerprint rotation acquisition surface 4.

[0040] The image acquisition device includes an image acquisition support plate 13 and an image acquisition camera 14. The image acquisition support plate 13 is vertically fixed at both ends within the inner identification protective shell 2, such that the longitudinal line of the image acquisition support plate 13 is parallel to the axis of the fingerprint rotating acquisition surface 4, and the image acquisition support plate and the supplementary lighting support plate 11 are symmetrical about the axis of the fingerprint pressing window 6. The image acquisition camera 14 is fixedly mounted on the image acquisition support plate 13 and faces the fingerprint pressing window 6, so as to capture an image of the fingerprint pressed on the first side of the fingerprint rotating acquisition surface 4 through the second side of the fingerprint rotating acquisition surface 4. The captured fingerprint is then transmitted to the circuit board 3 for fingerprint comparison to complete the fingerprint acquisition and recognition.

[0041] The surface sterilization and cleaning component includes a guide slide, a sliding power component, and a wiping sterilization and cleaning component. The guide slide and the sliding power component are both mounted on the inner identification protective shell 2, and the wiping sterilization and cleaning component is mounted on the guide slide. The guide slide includes a guide slide rod 15, a guide slide sleeve 16, and a guide slide wiping seat 17. The two ends of the guide slide rod 15 are vertically fixed within the inner identification protective shell 2. The guide slide sleeve 16 is slidably fitted onto the guide slide rod 15, allowing it to reciprocate axially along the guide slide rod 15. The guide slide wiping seat 17 is shaped like a right-angled plate and is fixed to the guide slide sleeve 16 at its right angle. This allows the sliding wiping seat to move along with the vertical sliding of the guide slide sleeve 16.

[0042] The sliding power component includes a second motor 18, a second worm gear 19, a transmission nut 20, a transmission shaft 21, and a second worm wheel 22. The second motor 18 is fixedly mounted on the inner identification protective shell 2. The second worm gear 19 is fixedly mounted on the rotating shaft of the second motor 18. The transmission nut 20 is fixedly mounted on the guide sliding wiping seat 17. The transmission shaft 21 is a screw, with one end passing through the transmission nut 20 and fixedly mounted inside the inner identification protective shell 2. The other end of the transmission shaft 21 extends out of the inner identification protective shell 2 and meshes with the transmission nut 20. The second worm wheel 22 is fixedly mounted on the other end of the transmission shaft 21 and meshes with the second worm gear 19. When the second motor 18 drives the transmission shaft 21 to rotate, it will drive the guide sliding wiping seat 17 to move vertically via the transmission nut 20.

[0043] The wiping and sterilizing cleaning component includes a wiping plate 23, a wiping telescopic component, and a sterilizing liquid bladder. The wiping plate 23 is elastic and has a sterilizing flow cavity inside. The sterilizing flow cavity is elongated and its longitudinal line is parallel to the longitudinal line of the wiping plate 23. A sterilizing liquid flow through-hole is provided on one side of the wiping plate 23, with one end of each through-hole communicating with the sterilizing flow cavity. Multiple sterilizing liquid flow through-holes are provided and evenly distributed along the longitudinal direction of the wiping plate 23. A layer of wiping cotton is covered on one side of the wiping plate 23 to absorb the sterilizing liquid delivered by the sterilizing liquid flow through-holes and to wipe the side of the fingerprint rotating and collecting surface 4 to remove fingerprints and bacteria from the side of the fingerprint rotating and collecting surface 4. The two ends of the wiping plate 23 are fixedly connected to the two free ends of the guide sliding wiping seat 17, and the wiping plate 23 is arc-shaped to fit the arc-shaped side of the fingerprint rotation collection surface 4.

One end of the wiping telescopic main tube 25 is horizontally fixed to the transmission nut 20, one end of the wiping telescopic branch tube 26 is embedded in the other end of the wiping telescopic main tube 25, and the other end of the wiping telescopic branch tube 26 is horizontally fixed at the axial center of the wiping plate 23, and the wiping telescopic branch tube 26 communicates with the sterilization flow chamber. This allows the wiping telescopic branch tube 26 to drive the wiping plate 23 to contract inward and expand outward during the axial reciprocating sliding process within the wiping telescopic main tube 25. The magnetic coil 27 is fixedly embedded in the other end of the wiping telescopic tube 25, and is also sleeved on the other end of the wiping telescopic branch tube 26. When the magnetic coil 27 is supplied with direct current to generate a magnetic field, it will push the wiping telescopic branch tube 26 to slide back and forth within the wiping telescopic tube 25. A liquid passage hole 28 is provided on one side wall of the wiping telescopic tube 25, which allows the disinfectant solution in the disinfectant sac to flow into the wiping telescopic tube 25.

[0045] The sliding sealing reset component includes a relay telescopic tube 29, a sealing sliding plate 30, and a reset spring 31. The outer diameter of the relay telescopic tube 29 is smaller than the outer diameter of the wiping telescopic branch tube 26. One end of the relay telescopic tube 29 is horizontally connected to one end of the wiping telescopic branch tube 26.

The return spring 31 is sleeved on the outside of the relay telescopic tube 29, with one end of the return spring 31 connected to one end of the wiping telescopic branch tube 26 and the other end connected to the sealing sliding plate 30. This allows the return spring 31 to push the wiping telescopic branch tube 26 outward, ensuring a sliding seal between the relay telescopic tube 29 and the sealing sliding plate 30 as the relay telescopic tube 29 moves with the wiping telescopic branch tube 26.

[0046] The infusion opening and closing device includes an opening and closing support rod 32, an opening and closing transmission rod 33, an opening and closing cap 34, and an opening and closing plate 35.

[0047] When the wiping telescopic branch tube 26 is pushed to the left by the reset spring 31 to the predetermined position, it will cause the opening and closing cap 34 to completely block the through hole 36. When the wiping telescopic branch tube 26 is driven to the right by the magnetic coil 27, it will cause the opening and closing cap 34 to open the through hole 36, so that the disinfectant entering one end of the wiping telescopic main tube 25 can flow through the through hole 36 to the relay telescopic tube 29, and then flow through the wiping telescopic branch tube 26 to the disinfection flow chamber, and then flow through the disinfectant flow through hole to be absorbed on the wiping cotton, so as to wipe and disinfect the side of the fingerprint rotating collection surface 4.

Furthermore, the wiping sterilization and cleaning component is provided on the fourth side corresponding to the fingerprint rotation and collection surface 4.

[0049] The surface drying component includes a surface drying pipe 38 and a fan 39.
