Description

Technical Field

[0001] This application belongs to the field of identification device technology, and more specifically, relates to an ultra-thin, fast scanning document reading device. Background Technology

[0002] With social development and technological advancements, various card-based identification documents, such as the second-generation ID card, have been widely used in all sectors of society. When conducting business manually or through self-service at high-speed rail stations, airports, border crossings, banks, and government service halls, it is necessary to register or compare document or ticket information, using card-based identification document reading and image capture devices for information collection and comparison.

[0003] Current document scanning and recognition devices generally consist of a housing containing essential components such as a clamping conveyor mechanism, a card reader, and an image scanning module. The clamping conveyor mechanism uses upper and lower rollers to hold and transport cards. This traditional hard-contact transmission method suffers from problems such as card slippage, card surface wear, and dirt sticking to the rollers and cards. The clamping conveyor mechanism requires a drive system using motors, gear sets, or synchronous belts, resulting in a complex structure and relatively large size. Furthermore, the fixed internal scanning module makes internal cleaning inconvenient, affecting scanning quality. Summary of the Invention

[0004] To address one of the shortcomings of the existing technology, the purpose of this application is to provide an ultra-thin and fast document scanning and reading device.

[0005] To achieve the above objectives, the technical solution adopted in this application is: to provide an ultra-thin and fast scanning document reading device, comprising: a housing, a card insertion port at the front end of the housing, a suction component, a recognition component and a scanning component arranged sequentially inside the housing, the suction component being disposed close to the card insertion port, and a linear drive component being provided inside the housing, the linear drive component being used to transfer the card between the suction component, the recognition component and the scanning component;

[0006] The linear drive assembly includes a linear motor, a moving frame, and a clamping assembly. The linear motor includes a stator and a mover. The moving frame is fixed on the mover. The clamping assembly is disposed on the moving frame and clamps the two length sides of the card. The recognition assembly recognizes the card on the moving frame, and the scanning assembly scans the front and back of the card on the moving frame.

[0007] In one embodiment, the rear end of the housing is provided with an installation port, and a rebound device is provided inside the housing. The scanning component is inserted into the housing through the installation port. When the scanning component is pressed, the rebound device can eject part of the scanning component from the installation port.

[0008] In one embodiment, the clamping assembly includes at least four solenoid valves, each of which has a clamping block on its electromagnetic push rod. The four solenoid valves are arranged in a rectangular shape, and the extension and retraction directions of the electromagnetic push rods of the four solenoid valves are perpendicular to the card conveying direction.

[0009] In one embodiment, the clamping block is a rubber block, and each clamping block is provided with a groove whose length direction is the same as the card conveying direction, and the groove engages with the length side of the card.

[0010] In one embodiment, the identification component is disposed below the movable frame, and the identification component includes a non-contact base, a non-contact antenna plate disposed on the non-contact base, and a second-generation ID card box disposed within the non-contact base.

[0011] In one embodiment, the scanning assembly includes an end plate, an upper mounting plate and a lower mounting plate spaced apart on the end plate, the upper mounting plate being located above the moving frame and the lower mounting plate being located below the moving frame, the end plate being movably connected to the mounting port, the bouncer being elastically abutting against the end plate, an upper scanner being provided on the upper mounting plate, a lower scanner being provided on the lower mounting plate, and a linear drive assembly driving the card to move between the upper mounting plate and the lower mounting plate.

[0012] In one embodiment, the rebounder includes a rebound base and a rebound rod, the end of the rebound rod is provided with a magnet, and the end plate is provided with a magnetic block that attracts the magnet.

[0013] In one embodiment, the suction assembly includes an upper rotating shaft, a lower rotating shaft, a gear set, and a rotary motor. The inner wall of the front end of the housing is provided with four mounting seats. The two ends of the upper rotating shaft and the lower rotating shaft are rotatably mounted on the mounting seats. The rotary motor is drivenly connected to one end of the lower rotating shaft, and the other end of the lower rotating shaft is drivenly connected to the upper rotating shaft through the gear set. The upper rotating shaft is provided with a driven anti-slip wheel, and the lower rotating shaft is provided with an active anti-slip wheel. The active anti-slip wheel and the driven anti-slip wheel clamp and transport the card.

[0014] In one embodiment, a medium sensing sensor is provided at the card insertion port; the front end of the housing is also provided with an upper directional wheel and a lower directional wheel that are configured to rotate vertically.

[0015] Another objective of this application is to provide an ultra-thin, fast scanning and reading method for identification documents, based on the ultra-thin, fast scanning and reading device described above, wherein the reading method includes:

[0016] Step 1: Insert the card into the card insertion slot. The media sensor detects the card, and the suction component starts working, clamping the card and moving it into the housing.

[0017] Step 2: After the card moves to the position of the clamping component, the clamping component clamps the two length sides of the card; at this time, the recognition component reads the media information on the card. If the media information is correct, proceed to the next step; if the media information is misaligned, the suction component rotates in the opposite direction, the clamping component cancels the clamping action, and the card is sent out through the card insertion port.

[0018] Step 3: The linear motor operates, driving the moving frame and the card held by the clamping component to continue moving into the housing; the scanning component scans the front and back of the card and acquires images as the card moves inward; if the scanned image is deemed acceptable, proceed to the next step; if the scanned image is deemed unacceptable, remove the scanning component from the housing, clean the dust from the scanning component, reinstall it, and scan the card again until the scanned image is deemed acceptable.

[0019] Step 4: After scanning is complete, the linear motor reverses its direction to transfer the card to the suction component, which then ejects the card, completing the recognition and scanning process.

[0020] The beneficial effects of the ultra-thin, high-speed document scanning and reading device and method provided in this application are as follows:

[0021] 1. The card is fed by a linear motor and a clamping assembly, which has the advantage of high transmission speed, thereby improving scanning efficiency;

[0022] 2. By using a linear motor and clamping assembly to transport cards, the problem of card slippage, surface wear, and dirt sticking to the rollers that exist in existing roller conveying technology is solved compared to roller conveying.

[0036] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0038] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0040] like Figures 1-8 As shown, an ultra-thin and fast document scanning and reading device provided in this application embodiment will now be described. This ultra-thin and fast document scanning and reading device includes: a housing 1, which has a rectangular structure; a card insertion port 11 is provided at the front end of the housing 1; a suction component 2, a recognition component 3, and a scanning component 4 are sequentially arranged inside the housing 1; the suction component 2 is located near the card insertion port 11; and a linear drive component 5 is also provided inside the housing 1, which is used to transfer the card between the suction component 2, the recognition component 3, and the scanning component 4.

[0041] Specifically, the linear drive assembly 5 includes a linear motor 51, a moving frame 52, and a clamping assembly 53. The linear motor 51 includes a stator and a mover. The working principle of the linear motor 51 is conventional and will not be described in detail here. The moving frame 52 is fixed on the mover. The opening size of the moving frame 52 is larger than the card size, allowing the scanning assembly 4 to scan the card through the opening in the moving frame 52. The clamping assembly 53 is set on the moving frame 52 and clamps the two long sides of the card, allowing the card to be transported in suspension. The recognition assembly 3 recognizes the card on the moving frame 52, and the scanning assembly 4 scans the front and back of the card on the moving frame 52. When the linear motor 51 is working, the moving frame 52 is driven to move as the mover moves. The movement of the moving frame 52 enables the clamping assembly 53 and the card to move synchronously, thereby realizing the transfer of the card between the suction assembly 2, the recognition assembly 3, and the scanning assembly 4.

[0042] In this embodiment, the card is transported by the linear motor 51 and the clamping component 53, which has the advantage of fast transmission speed, thereby improving scanning efficiency. Moreover, compared with the prior art of transporting the card by clamping the upper and lower surfaces of the card with rollers, it solves the problems of card slippage, surface wear and roller dirt sticking that exist in roller transport. At the same time, the card is transported in the air, so the scanning component 4 does not come into direct contact with the card, and there is no problem that the stains on the card will affect the scanning component 4.

[0043] like Figure 1 , Figure 2 , Figure 5 and Figure 8 As shown, in this embodiment, the scanning component 4 is detachably installed inside the housing 1. Specifically, the rear end of the housing 1 has an installation port, and two rebounders 6 are provided inside the housing 1. The scanning component 4 is inserted into the housing 1 through the installation port. When the scanning component 4 is pressed on the outside of the housing 1, the rebounder 6 can eject part of the scanning component 4 from the installation port, which facilitates the removal of the scanning component 4 for alignment and cleaning. Two rebounders 6 are provided, each including a rebound base 61 and a rebound rod 62. The end of the rebound rod 62 is provided with a magnet 63, and the end plate 41 of the scanning component 4 is provided with a magnetic block 64 that attracts the magnet 63. The magnetic block 64 can be an iron block or a magnetic block. When the scanning component 4 is normally inserted into the housing 1, the magnetic block 64 attracts the magnet 63 to ensure the stability of the installation of the scanning component 4. When it is necessary to remove the scanning component 4, the external pressure on the scanning component 4 causes the rebound rod 62 of the rebounder 6 to push the scanning component 4 out, and then the scanning component 4 is pulled out, and the magnet 63 separates from the magnetic block 64.

[0044] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the clamping assembly 53 includes at least four solenoid valves 531, which are arranged in a rectangular shape on the moving frame 52. Each solenoid valve 531 has a clamping block 532 on its electromagnetic push rod. The extension and retraction directions of the electromagnetic push rods of the four solenoid valves 531 are perpendicular to the card conveying direction. When a card is conveyed between the four solenoid valves 531 by the suction assembly 2, the solenoid valves 531 operate, and the electromagnetic push rods extend, causing the clamping blocks 532 to clamp the length side of the card. Specifically, the clamping blocks 532 are rubber blocks, and each clamping block 532 has a groove 533 with the same length direction as the card conveying direction. The grooves 533 engage with the length side of the card. The grooves 533 ensure that the card will not fall off after being clamped. The rubber blocks have a certain degree of elasticity, which can effectively protect the card during clamping.

[0045] In this embodiment, the identification component 3 is located below the movable frame 52. The identification component 3 includes a contactless base 31, a contactless antenna plate 32 disposed on the contactless base 31, and a second-generation ID card box 33 disposed within the contactless base 31. The contactless antenna plate 32 is used to identify cards such as bank cards, and the second-generation ID card box 33 is used to identify ID cards.

[0046] like Figure 1 , Figure 5 and 8 As shown, the scanning assembly 4 includes an end plate 41, an upper mounting plate 42 and a lower mounting plate 43 spaced apart on the end plate 41, the upper mounting plate 42 and the lower mounting plate 43 being arranged parallel to each other, the upper mounting plate 42 being located above the moving frame 52, and the lower mounting plate 43 being located below the moving frame 52. The end plate 41 is movably inserted into the mounting port, and the bouncer 6 elastically abuts against the end plate 41. The upper mounting plate 42 is provided with an upper scanner 44, which scans the upper surface of the card, and the lower mounting plate 43 is provided with a lower scanner 45, which scans the lower surface of the card. The linear drive assembly 5 drives the card to move between the upper mounting plate 42 and the lower mounting plate 43, without the card contacting the upper scanner 44 and the lower scanner 45.

[0047] like Figure 3 , Figure 4 and Figure 6 As shown, in this embodiment, the suction assembly 2 includes an upper rotating shaft 21, a lower rotating shaft 22, a gear set 23, and a rotary motor 24. The inner wall of the front end of the housing 1 is provided with four mounting seats 25. The two ends of the upper rotating shaft 21 and the lower rotating shaft 22 are rotatably mounted on corresponding mounting seats 25. The rotary motor 24 is driven by one end of the lower rotating shaft 22, and the other end of the lower rotating shaft 22 is driven by the upper rotating shaft 21 through the gear set 23. The upper rotating shaft 21 is provided with a driven anti-slip wheel 26, and the lower rotating shaft 22 is provided with an active anti-slip wheel 27. The active anti-slip wheel 27 and the driven anti-slip wheel 26 clamp and transport the card. When the rotary motor 24 operates, it drives the lower rotating shaft 22 to rotate. Simultaneously, the rotation of the lower rotating shaft 22 drives the upper rotating shaft 21 to rotate through the gear set 23. The rotation direction of the upper rotating shaft 21 is opposite to that of the lower rotating shaft 22, so that the active anti-slip wheel 27 and the driven anti-slip wheel 26 can rotate synchronously and clamp and transport the card.

[0048] To ensure straight-line card transport, an upper directional wheel 28 and a lower directional wheel 29 are provided inside the front end of the housing 1, which are configured to rotate vertically. The upper directional wheel 28 and the lower directional wheel 29 are respectively rotatable via a rotating shaft, with the upper directional wheel 28 horizontally spaced from the upper rotating shaft 21. The upper directional wheel 28 and the lower directional wheel 29 each have a clamping point for the card, and the active anti-slip wheel 27 and the driven anti-slip wheel 26 each have a clamping point for the card. The two clamping points ensure that the card is in a straight line, which facilitates the subsequent clamping assembly 53 in clamping the card.

[0049] In this embodiment, a media sensing sensor is provided at the card insertion slot 11. When the paper receiving sensor detects a card being inserted, the rotary motor 24 starts working to suck up the card. Inside the housing 1, two position sensors are arranged at intervals corresponding to the positions of the solenoid valves 531 along the card conveying direction. The one closer to the card insertion slot 11 is the first position sensor, and the other is the second position sensor. When the position sensor (second position sensor) farther from the card insertion slot 11 senses a card, the rotary motor 24 stops working, and the four solenoid valves 531 operate, causing the clamping block 532 to clamp the card. After the recognition component has completed its work, the rotary motor 24 and the linear motor 51 work synchronously again to convey the card. When the card is removed from the active anti-slip wheel 27 and the driven anti-slip wheel 26 (after the first position sensor near the card insertion slot 11 detects no card), the rotary motor 24 stops working, and the linear motor 51 continues working until the card scanning is completed. When ejecting the card, the rotary motor 24 and the linear motor 51 both operate in reverse.

[0050] This embodiment also provides an ultra-thin, fast scanning and reading method for identification documents. Based on the ultra-thin, fast scanning and reading device described above, the reading method includes:

[0051] Step 1: Start the device and insert the card into the card insertion port 11. The medium sensing sensor detects the card, and the suction component 2 starts to work, clamping the card and moving it into the housing 1.

[0052] Step 2: After the card moves to the position of the clamping component 53, the clamping component 53 clamps the two length sides of the card. At this time, the identification component 3 reads the media information on the card. If the media information is correct, the next step is performed. If the media information is misaligned, the suction component rotates in the reverse direction, the clamping component 53 cancels the clamping action, and the card is sent out through the card insertion port 11. Specifically, the suction component conveys the card into the housing 1. After being detected by the second position sensor, the suction component stops working, the four solenoid valves 531 work, driving the electromagnetic push rod to extend, so that the clamping block 532 clamps the length sides of the card. In this state, part of the card is still clamped by the suction component 2. In this state, the identification component 3 can also read and judge the card information. If the judgment is correct, the next scanning work is performed; or if the judgment is incorrect, the card is ejected.

[0053] Step 3: After identification is completed, the rotary motor 24 and the linear motor 51 work synchronously, driving the moving frame 52 and the card held by the clamping component 53 to continue moving into the housing 1. The scanning component 4 scans both sides of the card and acquires images as it moves inward. If the scanned image is deemed acceptable, the next step is performed. If the scanned image is deemed unacceptable, the scanning component 4 is removed from the housing 1, cleaned, reinstalled, and the card is scanned again until the scanned image is deemed acceptable. Specifically, when the first position sensor near the card insertion port detects no card, it indicates that the card has detached from the suction component 2, and the rotary motor 24 stops working; the linear motor 51 continues working until the scanning component 4 completes the image scanning.

[0054] Step 4: After scanning is complete, the linear motor 51 reverses its direction, transferring the card to the suction assembly 2, which then ejects the card, completing the identification and scanning process. Specifically, when the first position sensor near the card insertion port 11 detects a card, the rotary motor 24 reverses its direction. When the medium sensing sensor detects a card, the linear motor 51 stops, the solenoid valve 531 operates, the electromagnetic push rod retracts, the clamping block 532 separates from the card, and the rotary motor 24 continues to operate until the medium sensing sensor detects no card. At this point, the rotary motor 24 stops, and the user removes the card.

[0055] In this embodiment, during the card information reading and scanning process, the card is suspended in the air, which can effectively prevent internal dust and debris from adhering to the card. At the same time, the suspended card does not contact the scanning component 4, so dust will not accumulate on the scanning component 4. During the transmission process, the linear motor 51 directly transports the card, which will not cause the card to slide and cause the scanning process to break.

[0056] In this embodiment, the scanning component 4 is connected to the power supply inside the housing 1 using the plug-in mode in the prior art. When the scanning component 4 is pulled out, the scanning component 4 is automatically powered off. After the scanning component 4 is cleaned, it is pressed back in and plugged into the power supply inside the housing 1 to achieve automatic electrical connection.

[0057] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
