Description

Technical Field

[0001] This invention relates to the field of big data acquisition technology, and in particular to an image information acquisition device for data acquisition. Background Technology

[0002] A scanner is a common device that converts physical media such as certificates and paper documents into digital images. It is widely used in government, finance, and enterprises for the collection and processing of certificates and documents. These devices typically have built-in or external cameras to complete image acquisition and further utilize image processing technology to perform operations such as cropping, enhancement, and recognition on the acquired images. This enables the digital extraction and structured storage of key information, thereby providing basic data support for subsequent business processes such as identity verification, business archiving, and information comparison.

[0003] However, when scanners are used in public places to scan images involving identity information or confidential documents, the scanned documents or files need to be fully unfolded and exposed to the device's lens during the operation. In this state, since most current devices are not equipped with dedicated privacy shielding structures, people in the vicinity or hidden cameras may directly spy on, photograph, or copy sensitive information on the scanned objects without the user's knowledge. This can easily lead to the leakage of personal privacy or even more serious security incidents, posing significant information security risks to related business systems. Summary of the Invention

[0004] This invention provides an image information acquisition device for data collection, which addresses the problem that when a scanner is used in a public place to scan images involving identity information or confidential documents, the scanned document or file needs to be fully unfolded and exposed to the device's lens during operation. In this state, since most current devices are not equipped with a dedicated anti-peeping shielding structure, people in the vicinity or hidden cameras may directly spy on, photograph, or copy sensitive information on the scanned object without the user's knowledge. This can easily lead to the leakage of personal privacy or even more serious security incidents, posing significant information security risks to related business systems.

The bottom of the suction plate has a suction plate opening. A swing arm drive is fixedly connected to the bottom of the scanning stage. The swing arm drive is connected to and drives the swing arm screw, which is rotatably connected to the bottom of the scanning stage. A spiral push block is slidably connected to the bottom of the scanning stage via a guide rod. The spiral push block is spirally connected to the swing arm screw. A spiral push rod is fixedly connected to the rear end of the spiral push block. A swing push groove is opened in front of the page-turning swing arm. The spiral push rod is slidably connected in the swing push groove. A light-transmitting top plate is fixedly connected inside the scanner housing. The light-transmitting top plate is located above the scanning stage. Two data acquisition cameras are fixedly connected to the light-transmitting top plate.

[0006] Furthermore, a guide groove is provided on the upper surface of the scanning stage, and a limiting groove is provided through the center of the guide groove. A movable stage is slidably connected inside the guide groove, and a movable push plate is fixedly connected to the middle of the rear edge of the bottom surface of the movable stage. The movable push plate is slidably connected inside the limiting groove.

[0007] Furthermore, a stage drive motor is installed at the bottom of the scanning stage by screws. The stage drive motor shaft is connected to and drives a stage screw that is rotatably connected to the bottom of the scanning stage. The moving push plate is screwed to the stage screw.

[0008] Furthermore, a front limiting strip is fixedly connected to the front edge of the upper surface of the moving stage, and a rear limiting strip is fixedly connected to the upper surface of the scanning stage.

[0009] Furthermore, a side limiting wedge is fixedly connected to the left and right edges of the upper surface of the scanning stage.

[0010] Furthermore, a rocker arm pusher cylinder is fixedly connected to the rear of the page-turning rocker arm, and a pusher slide groove is provided at the rear of the page-turning rocker arm.

[0011] Furthermore, a rocker arm push block is fixedly connected to the rear surface of the telescopic rocker arm, the rocker arm push block is slidably connected inside the push block groove, and the push rod end of the rocker arm push cylinder is fixedly connected to the rocker arm push block.

[0012] Furthermore, the middle part of the light-transmitting top panel has an arc-shaped structure. The light-transmitting top panel is made of white semi-transparent acrylic sheet. The arc-shaped structure of the light-transmitting top panel has two camera openings. Two data acquisition cameras are fixedly connected inside the two camera openings, and the two data acquisition cameras are located on the left and right halves of the light-transmitting top panel, respectively.

[0013] Furthermore, four supplementary lighting strips are fixedly connected to the upper surface of the light-transmitting top plate. The supplementary lighting strips are LED strips, and the LED beads of the supplementary lighting strips face the upper arc surface that is attached to the light-transmitting top plate.

[0014] Furthermore, the control panel is connected to the stage drive motor, vacuum pump, and swing arm drive via electrical connection wires.

[0015] This invention provides an image information acquisition device for data acquisition, which has the following beneficial effects: This invention features an image information inlet. Documents or files are inserted into the scanner housing through this inlet for scanning. The entire scanning process is completed within a closed cavity, preventing outsiders from directly seeing the content on the surface of the scanned object. This effectively avoids the risk of information leakage or unauthorized photography when used in public places. Simultaneously, guide grooves and limiting grooves are provided on the scanning table, with an internal sliding connection to a moving stage. A moving stage drive motor and lead screw drive the moving push plate back and forth. Combined with front limiting strips, rear limiting strips, and side limiting wedges, precise positioning and limiting of documents or papers of different sizes can be achieved, ensuring that the scanned object is in the same acquisition area each time, improving the consistency of image acquisition.

[0016] Furthermore, the structure employs a page-turning swing arm, a telescopic swing rod, a vacuum suction plate, and a vacuum pump, along with a swing arm drive, swing arm screw, spiral push block, and spiral push rod. This allows for automatic paper suction and page-turning with the document's axis as the center. A swing rod push cylinder is fixed behind the page-turning swing arm. The rear surface of the telescopic swing rod is connected to a swing rod push block, which slides within the push block's groove. The extension and retraction of the telescopic swing rod are controlled by the swing rod push cylinder. After page turning, the vacuum suction plate is pushed outwards, ensuring the image information is completely and unobstructed beneath the data acquisition camera. This enables continuous automatic scanning of multiple pages without manual page turning, improving scanning efficiency and operational convenience.

[0017] Furthermore, the translucent top panel is made of white semi-transparent acrylic sheet, with a curved structure in the middle. Four supplementary lighting strips are fixedly connected to the top of the panel, and the LED strips face upwards towards the curved surface of the top panel. The light diffuses through the top panel, evenly illuminating the surface of the scanned object, avoiding localized overexposure or shadows, significantly improving illumination uniformity. This ensures clear images acquired by the data acquisition camera without light spot interference. The curved structure of the top panel has two camera openings, with two data acquisition cameras fixedly connected to the left and right halves respectively. Combined with the automatic page-turning mechanism, it can simultaneously or sequentially capture the contents of the left and right pages after they are turned, making it suitable for scanning books or bound documents, further expanding the device's applicability.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figures 1 to 12 : This invention proposes an image information acquisition device for data acquisition, comprising: a scanner housing 1, a control panel 2 fixedly connected to the front of the scanner housing 1, a scanning table 3 fixedly connected inside the scanner housing 1, an image information inlet 101 provided on the lower edge of the front surface of the scanner housing 1, a page-turning arm 4 hinged to the bottom of the scanning table 3 via a support rod, a telescopic arm 401 slidably connected inside the page-turning arm 4, a vacuum suction plate 5 connected to the end of the telescopic arm 401 via a rigid pipe, the vacuum suction plate 5 being connected to the rigid pipe and connected to a location below the scanning table 3 via a gas supply hose 502. Vacuum pump 503, vacuum suction plate 5 with suction plate through-hole 501 at the bottom, a swing arm drive 6 fixedly connected to the bottom of scanning stage 3, the swing arm drive 6 connected to and driving the swing arm screw 601 connected to the bottom of scanning stage 3, a spiral push block 603 slidably connected to the bottom of scanning stage 3 via guide rod 602, the spiral push block 603 spirally connected to the swing arm screw 601, a spiral push rod 604 fixedly connected to the rear end of spiral push block 603, a swing push groove 405 opened at the front of page turning swing arm 4, the spiral push rod 604 slidably connected in the swing push groove 405, and the scanner housing 1 is fixedly connected inside A light-transmitting top plate 7 is connected above the scanning table 3. Two data acquisition cameras 8 are fixedly connected to the light-transmitting top plate 7. Documents or files are placed inside the scanner housing 1 through the image information inlet 101, allowing information to be entered and preventing information leakage. Image information is acquired by the data acquisition cameras 8 located in the light-transmitting top plate 7. After a single page is acquired, the position of the spiral push block 603 is adjusted in conjunction with the swing arm drive component 6 to adjust the angle of the page-turning swing arm 4. The swing arm push cylinder 402 is then controlled to retract the telescopic swing arm 401, creating a vacuum. The suction plate 5 is located above the paper. The vacuum pump 503 generates negative pressure, causing the vacuum suction plate 5 to pick up the paper. With the continuous cooperation of the swing arm drive 6 and the page-turning swing arm 4, the vacuum suction plate 5 rotates around the document's axis to achieve automatic page turning. After page turning, the swing arm push cylinder 402 pushes the telescopic swing arm 401 and the vacuum suction plate 5 outward, exposing the image information unobstructed under the two data acquisition cameras 8. The light strip 702 illuminates the light-transmitting top plate 7, which disperses the light and provides uniform illumination to the image, improving the uniformity of illumination.

[0024] In this embodiment, a guide groove 301 is provided on the upper surface of the scanning stage 3. A limiting groove 302 is provided through the center of the guide groove 301. A movable stage 303 is slidably connected inside the guide groove 301. A movable push plate 306 is fixedly connected to the middle of the rear edge of the bottom surface of the movable stage 303. The movable push plate 306 is slidably connected inside the limiting groove 302. A stage drive motor 307 is installed at the bottom of the scanning stage 3 by screws. The shaft of the stage drive motor 307 is connected to and drives a stage screw 308 that is rotatably connected to the bottom of the scanning stage 3. The movable push plate 306 is screwed to the stage screw 308. A front push plate 306 is fixedly connected to the front edge of the upper surface of the movable stage 303. The upper surface of the scanning stage 3 is fixedly connected to a rear limit bar 305 and a side limit wedge 309, respectively, on the left and right edges of the upper surface of the scanning stage 3. The scanning stage 3 has a guide groove 301 and a limit through groove 302, and a moving stage 303 is slidably connected inside. The moving stage drive motor 307 and the moving stage screw 308 drive the moving push plate 306 to move back and forth. With the front limit bar 304, the rear limit bar 305 and the side limit wedge 309, the document or paper of different sizes can be accurately positioned and limited, ensuring that the scanned object is in the same acquisition area each time it is scanned, thus improving the consistency of image acquisition.

[0025] In this embodiment, a swing arm pusher cylinder 402 is fixedly connected to the rear of the page-turning swing arm 4, and a push block groove 403 is provided at the rear of the page-turning swing arm 4. A swing arm pusher block 404 is fixedly connected to the rear surface of the telescopic swing arm 401, and the swing arm pusher block 404 is slidably connected inside the push block groove 403. The push rod end of the swing arm pusher cylinder 402 is fixedly connected to the swing arm pusher block 404. The page-turning swing arm 4 is fixedly connected to the rear of the page-turning swing arm 4, and the telescopic swing arm 401 is connected to the swing arm pusher block 404 and slides in the push block groove 403. The telescopic swing arm 401 is extended and retracted by the swing arm pusher cylinder 402. After the page is turned, the vacuum suction plate 5 is pushed outward, so that the image information is completely and unobstructed under the data acquisition camera 8, realizing continuous automatic scanning of multi-page documents without manual page turning.

[0026] In Example 2, based on Example 1, the middle part of the translucent top panel 7 has an arc-shaped structure. The translucent top panel 7 is made of white semi-transparent acrylic sheet. Two camera openings 701 are provided through the arc-shaped structure of the translucent top panel 7. Two data acquisition cameras 8 are fixedly connected inside the two camera openings 701, located on the left and right halves of the translucent top panel 7 respectively. Four supplementary lighting strips 702 are fixedly connected to the upper surface of the translucent top panel 7. The supplementary lighting strips 702 are LED strips, with the LED beads facing upwards and conforming to the upper arc surface of the translucent top panel 7. The control panel 2 is connected to the stage drive motor 307, vacuum pump 503, and swing arm drive component 6 via electrical connection wires. 2. The stage drive motor 307, vacuum pump 503, and swing arm drive 6 are connected by electrical connection wires, realizing centralized control of the entire scanning and page turning process. The light diffuses after passing through the light-transmitting top plate 7 and then evenly illuminates the surface of the scanned object, avoiding local over-brightness or shadows, and significantly improving the uniformity of illumination. This ensures that the image quality acquired by the data acquisition camera 8 is clear and free of light spot interference. The arc-shaped structure of the light-transmitting top plate 7 has two camera openings 701. The two data acquisition cameras 8 are fixedly connected to the left and right halves respectively. With the automatic page turning mechanism, the contents of the left and right pages after they are turned can be collected simultaneously or in stages. It is suitable for scanning books or bound documents, further expanding the applicability of the device.

[0027] The working principle of this embodiment is as follows: During use, the operator inserts the document or file to be scanned into the image information inlet 101 at the lower edge of the front surface of the scanner housing 1, allowing it to enter the scanner housing 1 and be placed on the scanning table 3. The moving stage 303, driven by the moving stage drive motor 307 and the moving stage screw 308, rotates, causing the moving push plate 306 to slide back and forth along the limiting groove 302, thereby pushing the document or paper on the moving stage 303 between the front limiting bar 304 and the rear limiting bar 305. At the same time, the side limiting wedge bar 309 limits the left and right directions, ensuring that the scanned object is accurately located below the two data acquisition cameras 8. Subsequently, the supplementary light strip 702 located on the light-transmitting top plate 7 emits light, which is diffused through the light-transmitting top plate 7 made of white semi-transparent acrylic and its curved structure, evenly illuminating the surface of the document or paper, avoiding local overexposure or shadows. The data acquisition camera 8 acquires image information through the camera throughlet 701, completing the pickup of a single page or sheet. When continuous scanning of multi-page documents or books is required, the swing arm drive 6 drives the swing arm screw 601 to rotate, causing the spiral push block 603 to move back and forth along the guide rod 602. The spiral push rod 604 at the rear end of the spiral push block 603 slides in the swing push groove 405 in front of the page-turning swing arm 4, thereby adjusting the angle of the page-turning swing arm 4. At this time, the swing arm push cylinder 402 pushes the swing arm push block 404 to slide in the push block slide groove 403 through the push rod, so that the telescopic swing arm 401 extends and retracts relative to the page-turning swing arm 4, moving the vacuum suction plate 5 at the end to above the paper. The vacuum pump 503 starts, and through the air supply hose 502 and rigid pipe, a negative pressure is generated in the suction plate throughlet 501 at the bottom of the vacuum suction plate 5, which firmly adsorbs the paper. After that, the swing arm drive 6 continues to drive the page-turning swing arm. Arm 4 rotates around the document's axis, while the swing arm push cylinder 402 coordinates with the telescopic swing arm 401 to lift and flip the adsorbed paper to the other side. After the page is flipped, the swing arm push cylinder 402 pushes the telescopic swing arm 401 and the vacuum suction plate 5 outward, so that the flipped paper is fully unfolded and exposed without obstruction to the two data acquisition cameras 8 for image acquisition again. Throughout the scanning and page-flipping process, the control panel 2 coordinates the start and stop of the stage drive motor 307, the vacuum pump 503, and the swing arm drive component 6 through electrical connection lines, realizing automated continuous pickup. At the same time, due to the closed structure of the scanner housing 1, sensitive information on the scanned object cannot be viewed from the outside, ensuring information security for use in public places.
