[0001] This invention relates to the field of information acquisition technology, specifically to a computer information acquisition device. Background Technology

[0002] Computer information acquisition devices are used to digitize information carriers such as paper documents, drawings, and physical objects. They mainly collect information such as text, images, and symbols on the carriers and convert them into digital signals that can be recognized by computers. Among these devices, document scanners have become the mainstream equipment for document scanning and information acquisition due to their advantages such as high portability, fast acquisition speed, and clear imaging. They achieve information acquisition from carriers such as paper documents through scanning head scanning and image processing technology.

[0003] Currently, when using document scanners, especially when dealing with large documents, the limited effective scanning range often necessitates dividing the document into multiple parts and using a step-by-step scanning method to complete the overall information collection, thus reducing the overall efficiency of information collection.

[0008] Furthermore, the adjustment assembly includes a mounting plate fixedly connected to one side of the U-shaped frame, mounting frames fixedly connected to both sides of the mounting plate, and a first electric push rod installed on both sides of the mounting plate. The first electric push rod is fixedly connected to the mounting frame, and the movable end of the first electric push rod is fixedly connected to the arc-shaped track.

[0009] Furthermore, the rolling assembly includes four rollers that are rotatably connected to two arc-shaped tracks. A U-shaped frame is rotatably connected to one side of each of the four rollers. A first servo motor is installed on one side of each of the four rollers. The first servo motor is installed on one side of the U-shaped frame. A support frame is fixedly connected to the bottom of the U-shaped frame. Two limit wheels are rotatably connected inside the support frame. The limit wheels are rotatably connected to the two arc-shaped tracks. A first circular plate is fixedly connected to the bottom of the support frame.

[0010] Furthermore, the drive assembly includes an L-shaped connecting plate fixedly connected to the bottom of the first circular plate. A second servo motor is mounted on one side of the L-shaped connecting plate. A rotating shaft is fixedly connected to the output end of the second servo motor. A gear is fixedly connected to one end of the rotating shaft. A gear ring is meshed with the outer wall of the gear. A rotating seat is rotatably connected to the bottom of the first circular plate.

[0018] By using a dual-axis tilt sensor to detect the tilt of the scanning head in real time, and in conjunction with the angle compensation and positioning components, the tilt can be automatically corrected without manual shutdown for calibration or replacement of worn parts. This not only saves calibration time and reduces the difficulty of operation, but also reduces efficiency loss caused by downtime.

[0019] By cooperating with the drive component and the snap-fit ​​component, the lifting component is raised and lowered, which makes it easy to adjust the scanning head to the optimal focal length position, avoids image blurring or range deviation caused by improper height, and improves the adaptability of the device.

[0020] By setting the limiting components, the movement and shaking caused by the extension and retraction of the track are avoided, ensuring that the scanning head maintains a stable posture when moving on the arc track, thus guaranteeing the clarity of the scanned image and the scanning effect.

[0032] 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 embodiments of the present invention, and not all embodiments. Based on the 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.

[0033] To address the technical issue of low overall efficiency caused by using a step-by-step scanning method when dealing with large documents, such as... Figures 1-10 As shown, the following preferred technical solutions are provided:

[0034] A computer information acquisition device includes a base plate 1, which can support and fix various components and facilitate the placement of information carriers such as paper documents, drawings, and physical objects to be acquired. A controller is installed on one side of the base plate 1 to facilitate the control of various electrical components. The controller is existing technology and is not shown in the figure. Two support rods 2 are arranged parallel to each other on the top of the base plate 1. A frame 21 is provided on the outer wall of the two support rods 2. Several mounting blocks 22 are provided on the outer wall of the frame 21. A limit component 3 is provided at the bottom of the mounting block 22. Two arc-shaped tracks 4 are slidably arranged inside the limit component 3. The limit component 3 is provided in two sets for limiting the two arc-shaped tracks 4. An adjustment component 5 is provided on one side of the limit component 3 and is connected to the two arc-shaped tracks 4. A rolling component 6 is rollingly connected inside the arc-shaped tracks 4. A drive component 7 is provided at the bottom of the rolling component 6. A lifting component 8 is provided at the bottom of the rolling component 6. A locking component 9 is provided at the top of the lifting component 8 and is locked to the drive component 7. A positioning component 10 is rollingly arranged at the bottom of the lifting component 8. A detection component 20 is provided on one side of the positioning component 10.

[0035] The detection component 20 has a scanning head 30 installed at its bottom. The scanning head 30 is connected to an external computer and can move along two arc-shaped tracks 4 under the drive of the rolling component 6 to dynamically scan the information carrier, capture information such as text, images and symbols on its surface and convert them into digital signals that can be recognized by the computer, thereby realizing information acquisition. The detection component 20 can detect whether the scanning head 30 is tilted. A laser distance sensor 301 is installed on one side of the scanning head 30, which can detect the distance between the scanning head 30 and the information carrier. When the laser distance sensor 301 detects that the distance of the scanning head 30 exceeds the threshold, it sends a signal to the controller, triggering the drive component 7 and the lifting component 8 to cooperate in adjusting the height of the scanning head 30 to the optimal scanning height.

[0036] In use, the information carriers such as paper documents, drawings, and physical objects to be scanned are placed on the surface of the base plate 1 and fixed and pressed by the external positioning structure. Then, according to the lateral dimensions of the information carrier, the controller causes the adjusting component 5 to drive the two arc-shaped tracks 4 to slide within the limiting component 3 until the lateral scanning range of the scanning head 30 can cover the information carrier. This allows for convenient one-time complete scanning of information carriers with a large overall area, without the need to divide them into multiple parts for step-by-step operation. Compared with the step-by-step scanning method in the prior art, it can reduce operation steps and shorten the acquisition time. At the same time, it can avoid image stitching misalignment caused by step-by-step scanning, thereby improving the efficiency and completeness of information acquisition. Subsequently, the rolling component 6 drives the scanning head 30 to move on the two arc-shaped tracks 4. Before moving to the limiting component 3, the support structure inside the limiting component 3 protrudes to facilitate the support of the rolling component 6, making the movement of the rolling component 6 more stable. This avoids the overall elongation of the track affecting the scanning effect of the scanning head 30, ensuring that the scanning head 30 maintains a stable scanning state during the movement, guaranteeing the clarity and quality of the scanned image, and thus improving the reliability of information acquisition.

[0037] When the scanning height of the scanning head 30 needs to be adjusted based on the detection value of the laser distance sensor 301, the controller causes the drive component 7 to rotate to the previous height adjustment position. At this time, the drive component 7 corresponds to the position of the latching component 9. Then, the controller causes the latching component 9 to latch with the drive component 7. The drive component 7 then drives the latching component 9 and the lifting component 8 to rotate, causing the positioning component 10, the detection component 20, and the scanning head 30 to rise and fall. This facilitates the adjustment of the scanning height of the scanning head 30. It can adjust the scanning head 30 to the optimal focal length position according to the thickness, size, and scanning requirements of the information carrier, ensuring clear imaging of different types of information carriers, improving the adaptability of the device, and avoiding image blurring or range deviation caused by improper height. After the height adjustment of the scanning head 30 is completed, the controller causes the latching component 9 to disengage from the drive component 7. The lifting component 8 is equipped with an angle compensation component 40.

[0038] During use, when the rolling assembly 6 moves within the two arc-shaped tracks 4 for an extended period, its internal rolling structure will experience wear, such as... Figure 10As shown, when the detection value of the detection component 20 is abnormal, it is determined that the scanning head 30 is tilted. Subsequently, the controller causes the clamping structure in the positioning component 10 to release the clamping of the lifting component 8. Then, the controller causes the driving component 7 to drive the angle compensation component 40 to rotate to the side of the detection component 20 with a higher angle. Then, the controller causes the angle compensation component 40 to push the detection component 20 downward, causing the positioning component 10 to rotate at one end of the lifting component 8 until the detection data of the detection component 20 returns to the normal range, so that the scanning head 30 returns to the horizontal position. This facilitates the subsequent scanning quality and avoids trapezoidal distortion, edge blurring, or missing information caused by tilting. This ensures the consistency of scanning content in different areas. Compared with the existing technology that requires manual shutdown for calibration or replacement of worn parts to correct the tilt, this method can automatically complete the angle compensation without manual intervention. It not only saves calibration time and reduces the difficulty of operation, but also reduces the efficiency loss caused by downtime. At the same time, it can adapt to the long-term wear of the rolling structure, extend the overall service life of the device, and improve the stability and reliability of information acquisition.

[0039] Then, the controller causes the clamping structure in the positioning component 10 to press the lifting component 8 again, thereby fixing the position of the scanning head 30. If the angle compensation is completed, and the detection value of the laser distance sensor 301 determines that the height of the scanning head 30 needs to be compensated, then the previous height adjustment steps are repeated.

[0040] like Figures 1-4 As shown, the limiting component 3 includes a U-shaped frame 31 fixedly connected to the bottom of the mounting block 22. Several first electromagnets 32 are evenly arranged inside the U-shaped frame 31. Several slide rods 33 are evenly arranged inside the U-shaped frame 31. A support block 34 is slidably connected to the outer wall of the slide rod 33. A slide plate 35 is fixedly connected to one end of the slide rod 33. The slide plate 35 is slidably connected to the support block 34. The slide plate 35 can limit the position of the support block 34 so that when it rises to the top, its upper surface remains horizontal with the inner wall of the arc track 4. A first magnet block 36 is installed at the bottom of the support block 34. A first spring 37 is fixedly connected to the bottom of the support block 34, and the other end of the first spring 37 is fixedly connected to the inner wall of the U-shaped frame 31.

[0041] like Figures 1-2 As shown, the adjustment component 5 includes a mounting plate 51 fixedly connected to one side of the U-shaped frame 31, mounting frames 52 fixedly connected to both sides of the mounting plate 51, and a first electric push rod 53 installed on both sides of the mounting plate 51. The first electric push rod 53 is fixedly connected to the mounting frame 52, and the movable end of the first electric push rod 53 is fixedly connected to the arc-shaped track 4.

[0042] like Figures 1-2 and Figures 5-9As shown, the rolling assembly 6 includes four rollers 61 that are rotatably connected to two arc-shaped tracks 4. A U-shaped frame 62 is rotatably connected to one side of each of the four rollers 61. A first servo motor 63 is installed on one side of each of the four rollers 61. The first servo motor 63 has a self-locking function and is installed on one side of the U-shaped frame 62. A support frame 64 is fixedly connected to the bottom of the U-shaped frame 62. Two limiting wheels 65 are rotatably connected inside the support frame 64. The limiting wheels 65 are rotatably connected to the two arc-shaped tracks 4. The limiting wheels 65 can limit the movement of the four rollers 61, so that they can roll more smoothly on the two arc-shaped tracks 4. A first circular plate 66 is fixedly connected to the bottom of the support frame 64.

[0043] like Figures 6-9 As shown, the drive assembly 7 includes an L-shaped connecting plate 71 fixedly connected to the bottom of the first circular plate 66. A second servo motor 72 is mounted on one side of the L-shaped connecting plate 71. The second servo motor 72 has a self-locking function. A rotating shaft 73 is fixedly connected to the output end of the second servo motor 72. A gear 74 is fixedly connected to one end of the rotating shaft 73. A gear ring 75 is meshed with the outer wall of the gear 74. A rotating seat 76 is rotatably connected to the bottom of the first circular plate 66. A rotating groove is provided on one side of the rotating seat 76. The rotating groove can limit the rotation of the rotating seat 76 and improve the stability of the rotation. The gear ring 75 is fixedly connected to the outer wall of the rotating seat 76. A snap-fit ​​sleeve 77 is fixedly connected inside the rotating seat 76. A snap-fit ​​groove 78 is provided inside the snap-fit ​​sleeve 77. A permanent magnet rotor 79 is fixedly connected to the bottom of the rotating seat 76.

[0044] like Figure 6 and Figures 8-10 As shown, the lifting assembly 8 includes a U-shaped connecting plate 81 fixedly connected to the bottom of the first circular plate 66. A ring 82 is fixedly connected inside the U-shaped connecting plate 81. A cylinder 83 is fixedly connected inside the U-shaped connecting plate 81. A threaded rod 84 is rotatably connected inside the cylinder 83. A threaded frame 85 is threadedly connected to the outer wall of the threaded rod 84. A limit groove is provided inside the cylinder 83, which can restrict the threaded frame 85 to move only along the direction of the cylinder 83 and not rotate. A rotating ball 86 is fixedly connected to the bottom of the threaded frame 85.

[0045] like Figures 8-9 As shown, the snap-fit ​​assembly 9 includes a positioning frame 91 fixedly connected to one end of the threaded rod 84. A second electromagnet 92 is installed inside the positioning frame 91. A snap-fit ​​block 93 is slidably connected inside the positioning frame 91. A second magnet block 94 is installed on one side of the snap-fit ​​block 93. A second spring 95 is fixedly connected to one side of the snap-fit ​​block 93, and the other end of the second spring 95 is fixedly connected to the inner wall of the positioning frame 91. The shape of the snap-fit ​​block 93 matches the shape of the snap-fit ​​groove 78, which facilitates subsequent rotation operations.

[0046] like Figure 6 , Figure 8 and Figure 10As shown, the positioning component 10 includes a rotating platform 101 that is rolled to the outer wall of the rotating ball 86. A small portion of the upper part of the rotating ball 86 is exposed above the rotating platform 101, which provides ample space for angle adjustment and avoids the rotating ball 86 being completely enclosed, thus restricting its rotation. At the same time, both the rotating ball 86 and the rotating platform 101 are precision mirror-polished to reduce the coefficient of friction when they rotate relative to each other, reduce wear and tear during long-term use, and ensure the flatness and smoothness of the contact surface. This prevents jamming or offset during angle compensation due to uneven frictional resistance, thereby ensuring the accuracy of the scanning head 30 when correcting its angle. A second electric push rod 102 is installed inside the rotating platform 101. An arc-shaped pressure plate 103 is fixedly connected to the movable end of the second electric push rod 102. The arc-shaped pressure plate 103 fits tightly against the rotating ball 86, and its shape matches the outer wall of the rotating ball 86, thereby improving the positioning effect.

[0047] like Figures 5-6 , Figure 8 and Figure 10 As shown, the detection assembly 20 includes a second circular plate 201 fixedly connected to the bottom of the rotating stage 101. A tilt sensor 202 is installed inside the second circular plate 201. The tilt sensor 202 is a dual-axis tilt sensor 202, which can conveniently detect the tilt angle data of the scanning head 30 in the horizontal and vertical directions at the same time, so as to realize a comprehensive judgment on the tilt state of the scanning head 30. During the initial calibration, the scanning head 30 is first adjusted to a horizontal position by an external level calibrator, and then the detection value of the dual-axis tilt sensor 202 is set to the normal range by the controller, thereby completing the calibration and ensuring the accuracy of subsequent tilt detection. The scanning head 30 is installed at the bottom of the second circular plate 201.

[0048] In use, the information carriers such as paper documents, drawings, and physical objects to be scanned are placed on the surface of the base plate 1 and fixed and pressed by the external positioning structure. Then, according to the lateral dimensions of the information carrier, the controller causes the first electric push rod 53 to drive the two arc-shaped tracks 4 to slide within the two U-shaped frames 31 until the lateral scanning range of the scanning head 30 can cover the information carrier. This allows for convenient one-time complete scanning of information carriers with a large overall area, without the need to divide them into multiple parts for step-by-step operation. Compared with the step-by-step scanning method in the prior art, it can reduce the operation steps and shorten the acquisition time. At the same time, it can avoid image stitching misalignment caused by step-by-step scanning, thereby improving the efficiency and completeness of information acquisition. Subsequently, the first servo motor 63 drives the four rollers 61 to rotate, so that the U-shaped frame... The servo motor 62 and support frame 64 drive the scanning head 30 to move on two arc-shaped tracks 4. Before moving to the U-shaped frame 31, the controller causes the first electromagnet 32 ​​inside the U-shaped frame 31 to repel the first magnet block 36, causing the support block 34 to slide out of the U-shaped frame 31 and stretch the first spring 37, which facilitates the bearing of the four rollers 61, making the movement of the four rollers 61 more stable. This avoids the overall elongation of the track affecting the scanning effect of the scanning head 30, and ensures that the scanning head 30 maintains a stable scanning state during the movement, thus guaranteeing the clarity and quality of the scanned image and improving the reliability of information acquisition. After scanning one information carrier, the first servo motor 63 drives the four rollers 61 to rotate in the opposite direction, so that the scanning head 30 returns to the initial position for the next scan.

[0049] When the laser distance sensor 301 detects that the scanning height of the scanning head 30 needs to be adjusted, the controller causes the second servo motor 72 to drive the rotating shaft 73 and gear 74 to rotate. Through the meshing of gear 74 and gear ring 75, the gear ring 75 rotates, causing the rotating seat 76 to rotate at the bottom of the first circular plate 66. This, in turn, causes the locking sleeve 77 to rotate to the previous height adjustment position. At this point, the slot 78 inside the locking sleeve 77 corresponds to the position of the locking block 93. Subsequently, the controller causes the second electromagnet 92 to repel the second magnet block 94, causing the locking block 93 to engage with the slot 78 and stretching the second spring 95, thus causing the drive assembly 7 to... The lifting assembly 8 is connected, and then the drive assembly 7 drives the locking assembly 9 and the threaded rod 84 to rotate, so that the threaded frame 85 drives the positioning assembly 10, the detection assembly 20 and the scanning head 30 to rise and fall. This makes it easy to adjust the scanning height of the scanning head 30. According to the thickness, size and scanning requirements of the information carrier, the scanning head 30 can be adjusted to the optimal focal length position to ensure clear imaging of different types of information carriers, improve the adaptability of the device and avoid image blurring or range deviation caused by improper height. After the height of the scanning head 30 is adjusted, the controller causes the locking block 93 to be de-engaged with the locking slot 78, so that the drive assembly 7 and the lifting assembly 8 are disconnected.

[0050] To address the technical issue that the scanning head 30 tends to tilt during prolonged use, such as... Figure 5 , Figure 6 and Figure 8 As shown, the following preferred technical solutions are provided:

[0051] like Figures 5-6 and Figure 8 As shown, the angle compensation component 40 includes a magnetic rotor 401 rotatably connected to the bottom of the ring 82. The magnetic field strength of the permanent magnet rotor 79 and the magnetic rotor 401 can ensure that when the second servo motor 72 drives the permanent magnet rotor 79 to rotate, the magnetic rotor 401 can rotate synchronously and stably. Two third electric push rods 402 are installed at the bottom of the magnetic rotor 401. The movable ends of the two third electric push rods 402 are provided with arc surfaces to reduce contact resistance when pushing the detection component 20, avoid scratches on the components or push jamming caused by hard contact, and at the same time adapt to slight position changes during angle adjustment, making the pushing action smoother. By setting two third electric push rods 402 and the two third electric push rods 402 being very close in position, it is possible to avoid the detection component 20 and the scanning head 30 shifting to one side due to unilateral force during angle adjustment, which can ensure the accuracy of angle compensation, ensure that the scanning head 30 stably returns to the horizontal position, and avoid generating new position deviations.

[0052] During use, when the four rollers 61 move within the two arc-shaped tracks 4 for an extended period, their internal rolling structure will experience wear. At this time, the detection value of the tilt sensor 202 will be abnormal, indicating that the scanning head 30 is tilted. Subsequently, the controller will cause the second electric push rod 102 to move the arc-shaped pressure plate 103, causing the arc-shaped pressure plate 103 to release its pressure on the rotating ball 86. Then, the controller will cause the second servo motor 72 to drive the rotating shaft 73 and gear 74 to rotate. Through the meshing of gear 74 and gear ring 75, the gear ring 75 will rotate, causing the rotating seat 76 and permanent magnet rotor 79 to rotate. Through the magnetic coupling between the permanent magnet rotor 79 and the magnetically guided rotor 401, the magnetically guided rotor 401 will drive the two third electric push rods 402 to rotate synchronously, causing the two third electric push rods 402 to rotate to the side of the second circular plate 201 with a higher angle.

[0053] Then, through the controller, the two third electric push rods 402 extend synchronously, pushing the second circular plate 201 downward, causing the rotating stage 101 to rotate on the outer wall of the rotating ball 86 until the detection data of the tilt sensor 202 returns to the normal range, so that the scanning head 30 returns to the horizontal position. This facilitates the subsequent scanning quality and avoids trapezoidal distortion, edge blurring, or missing information caused by tilting, thereby ensuring the consistency of scanning content in different areas. Compared with the existing technology that requires manual shutdown for calibration or replacement of worn parts to correct the tilt, this method can automatically complete the angle compensation without manual intervention. It not only saves calibration time and reduces the difficulty of operation, but also reduces the efficiency loss caused by shutdown. At the same time, it can adapt to the long-term wear of the rolling structure, extend the overall service life of the device, and improve the stability and reliability of information acquisition. At this time, through the controller, the second electric push rod 102 drives the arc-shaped pressure plate 103 to move, so that the arc-shaped pressure plate 103 presses the rotating ball 86 again, thereby fixing the position of the scanning head 30. If the height of the scanning head 30 needs to be compensated after the angle compensation is completed, the previous height adjustment steps are repeated.
