Description

[0002] With the rapid development of Internet technology, the ways of learning, working, and reading have gradually changed from paper-based to electronic-based, and the benefits of electronicization are obvious. For example, in the field of e-books, electronicization enables people to read interesting materials anytime and anywhere without carrying heavy books, but only need a mobile device. Another example is in the field of file management. The urgent problems faced by paper files include the storage, custody, and retrieval of paper files. On the one hand, the storage of paper files requires a large amount of space. If not properly stored, it is easy to be lost or damaged. Especially in the case of a large number of files, how to quickly find the required files has also become a major challenge. Electronicization can largely solve these problems. Electronic files occupy less space and are easy to store and retrieve.

[0003] Currently, mainly through scanning, paper books and the like are converted into electronic data. However, during the scanning process, especially during continuous scanning, when the current page is turned, it is necessary to press the next page to facilitate imaging of the next page. However, if the pressing block is too large, it will be displayed as a black block during imaging, or under the illumination of light, a shadow will be formed in the image, resulting in unclear imaging or difficult post-processing problems.

[0040] Hereinafter, the technical solutions according to the embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It should be noted that in the following description, the term "scanning object" refers to a carrier on which information can be recorded. The information recorded on the scanning object is converted into digital information through the scanning operation of the scanning device. The scanning object includes, for example, plain paper, coated paper, plastic sheets, and so on. In addition, although in the following description, the paper of a book is used as an example of the scanning object to describe the present disclosure, the scanning object can be, for example, a newspaper, a photo, a bill, and so on.

[0041] In the following description, although the force application device is described by taking a suction cup as an example, the force applied to the scanning object to separate the current scanning object (the first scanning object) from the subsequent scanning object (the second scanning object) is not limited to the adsorption force applied by the suction cup, but may include, for example, one or more of electrostatic adsorption force, magnetic adsorption force, and bionic adsorption force. And the generated force is not limited to the adsorption force, and may also be a thrust applied to the paper.

[0042] First, refer to Figure 1 , and describe the overall configuration of the scanning device 100 according to the present disclosure. As Figure 1 shown, the scanning device 100 according to the present disclosure includes a support device 110, a gripping device 120, a paging device 130, a page turning device 140, an imaging device 150, and an anti-rebound device 160. In addition, the scanning device 100 according to the present disclosure further includes a controller 200, and the controller 200 includes a central processing unit (CPU) 201 as a control unit.

[0043] In addition, the controller 200 includes a read-only memory (ROM) 202, a random access memory (RAM) 203, and a hard disk drive (HDD) 204. In addition, the controller 200 includes an interface 205. The ROM 202, the RAM 203, the HDD 204, and the interface 205 are connected to the CPU 201 via a bus. The basic program for operating the CPU 201 is stored in the ROM 202. The RAM 203 is a storage device in which various data such as the calculation processing results of the CPU 201 are temporarily stored. The HDD 204 is a storage device in which the calculation processing results of the CPU 201, the image data acquired by the imaging device 150, and so on are stored, and is also used to record the programs for causing the CPU 201 to execute various controls therein.

[0044] The CPU 201 controls the operations of the support device 110, the gripping device 120, the paging device 130, the page turning device 140, the imaging device 150, and the anti-rebound device 160 according to the programs recorded in the HDD 204.

[0045] Next, refer to Figure 2, a page turning device 100 according to an embodiment of the present disclosure is described. In Figure 1 , 101 is a suction cup mounting part, 102 is a clamping mechanism, 103 is a scanning support platform, 104 is a horizontal moving platform, 105 is a frame, 106 is a lifting mechanism, 107 is a scanning object, 108 is a page turning module (page turning device), 109 is a left anti-rebound mechanism, 110 is a page pressing mechanism, and 111 is a right anti-rebound mechanism.

[0046] In the embodiment of the present disclosure, the left-right direction in Figure 2 is defined as the x direction, the up-down direction is defined as the y direction, and the direction perpendicular to the xy plane is defined as the z direction.

[0047] As Figure 2 shown, the horizontal moving platform 104 is mounted on the bottom plate of the frame 105, and the horizontal moving platform 104 can move in the x direction along the guide rail, for example. In addition, the lifting mechanism 106 is fixedly mounted on the horizontal moving platform 104, and the scanning support platform 103 is mounted on the lifting mechanism 106. Therefore, the scanning support platform 103 can move in the y direction under the action of the lifting mechanism 106. In addition, the scanning support platform 103 can move in the x direction following the horizontal moving platform 104. In this way, the scanning support platform 103 according to the embodiment of the present disclosure can move in two degrees of freedom in the x direction and the y direction.

[0048] In addition, the page turning module 108 is mounted on the frame 105, and the page turning module 108 is connected to the suction cup mounting part 101 with a suction cup, and the page turning module 108 can move back and forth along the guide rail provided on the frame 105.

[0049] In addition, the left anti-rebound mechanism 109 and the right anti-rebound mechanism 111 are mounted on the scanning support platform 103, and the page pressing mechanism 110 is also mounted on the frame 105.

[0050] When performing the page turning operation, the clamping mechanism 102 is used to clamp the scanning object 107, and the horizontal moving platform 104 moves to the right so that the scanning object 107 is moved to a predetermined position. In addition, the page pressing mechanism 110 operates so that the page pressing manipulator rotates to a predetermined position, and then the lifting mechanism 106 operates to push the scanning object 107 upward until it contacts the page pressing manipulator and stops. In this way, the scanning object 107 can be moved to a predetermined position in the x direction and the y direction.

[0051] Next, with reference to Figure 3 and Figure 4 the page turning process for harder paper and softer paper is described.

[0052] With reference to Figure 3, describes the page turning process for relatively stiff (non-bendable or not allowed to be bent) paper. For relatively thick paper, since it cannot be bent, its page turning process is as follows:

[0053] S201: The page turning module 108 operates, driving the suction cup mounting part 101 to move downward until the suction cup on the suction cup mounting part 101 contacts the scanning object 107 and then stops.

[0054] S202: The page pressing mechanism 110 operates, causing the page pressing manipulator to move upward to a predetermined position and then stop to move away from the scanning object 107. Subsequently, the suction cup mounting part 101, the page turning module 104, and the horizontal moving platform 104 coordinate their actions to achieve the page opening action until the image acquisition position is reached.

[0055] Specifically, during the page turning process, while the page turning module 104 (suction cup) moves along the fixed track, the suction cup can rotate along the z-axis, and the horizontal moving platform 104 moves the scanning object in the x-direction so that the paper does not bend during the page turning process. The suction cup rotates along the z-axis, for example, by the hinge connection between the suction cup mounting part 101 and the page turning module 104.

[0056] S203: The page pressing mechanism 110 operates, and the page pressing manipulator moves downward until it contacts the scanning object 107 and then stops. After the image acquisition is completed, the suction cup releases the picked page, and at the same time, the right anti-rebound mechanism 111 operates, and the right page pressing rod moves to the left, pushing the page to the left side of the scanning object 107 and pressing it tightly.

[0057] S204: The left anti-rebound mechanism 109 operates, and the left page pressing rod presses the left-turned page tightly. Then, the right anti-rebound mechanism 111 operates, and the right page pressing rod returns to the initial position. Thus, the page turning action of one page of scanned data is completed.

[0058] Reference Figure 4 , describes the page turning process for relatively soft (bendable) paper. Since relatively soft paper can be bent, its page turning process is as follows:

[0059] S301: The page turning module 108 operates, driving the suction cup mounting part 101 to move downward until the suction cup on the suction cup mounting part 101 contacts the scanning object 107 and then stops.

[0060] S302: The page pressing mechanism 110 operates, causing the page pressing manipulator to move upward to a predetermined position and then stop to move away from the scanning object 107. Subsequently, the page turning module 108 operates, driving the picked page to move upward along the module to the image acquisition position.

[0061] S303: The page pressing mechanism 110 operates, and the page pressing manipulator moves downward until it contacts the scanning object 107 and then stops. After the image acquisition is completed, the suction cup releases the picked-up page. Meanwhile, the right anti-rebound mechanism 111 operates, and the right page pressing rod moves leftward to push the page to the left side of the scanning object 107 and press it tightly.

[0062] S304: The left anti-rebound mechanism 109 operates, and the left page pressing rod presses the left-turned page tightly. Then, the right anti-rebound mechanism 111 operates, and the right page pressing rod returns to the initial position. Thus, the page turning operation of one page of scanned material is completed.

[0063] As described above, in steps S203 and S303, image acquisition is performed when the page pressing mechanism 110 contacts the scanning object 107. However, if the overlapping part between the page pressing mechanism 100 and the scanning object is too large or due to the relatively high height of the page pressing mechanism 100, the page pressing mechanism 110 will appear as a shadow in the obtained image during image acquisition, or due to the light irradiation, the relatively high page pressing mechanism 100 will generate a projection on the scanning object, which may block key content, affect the clarity of the obtained image, and greatly increase the difficulty of removing the shadow through image processing subsequently.

[0064] For this reason, as Figure 5 shown, according to an embodiment of the present disclosure, a page pressing mechanism 110 is provided. The page pressing mechanism 110 is configured to press the scanning object during scanning, and the page pressing mechanism 110 includes an edge detection device 1101, a page pressing mechanism main body 1102, and an additional pressing part 1103.

[0065] The edge detection device 1101 is configured to detect the edge position of the scanning object. Specifically, for example, the edge detection device 1101 can detect the edge position of the scanning object by an optical method, so that the page pressing mechanism 110 can press near the edge position of the scanning object to minimize the occurrence of unclear imaging and other situations as much as possible.

[0066] The page pressing mechanism main body 1102 is configured to apply a pressing force to the scanning object according to the edge position of the scanning object detected by the edge detection device. Specifically, after the edge detection device 1101 detects the edge position of the scanning object, the scanning object is pressed according to the detection result. For example, the page pressing mechanism main body 1102 can press the area within 2 cm from the edge of the scanning object.

[0067] The additional pressing part 1103 is configured to press the scanning object, and the additional pressing part is connected to the main body of the page pressing mechanism and extends from the main body of the page pressing mechanism. That is to say, similar to the main body 1102 of the page pressing mechanism, the additional pressing part 1103 is also used to press the scanning object, but the additional pressing part 1103 does not completely coincide with the main body 1102 of the page pressing mechanism. Instead, it extends from the main body 1102 of the page pressing mechanism, and the additional pressing part 1103 is closer to the scanning object than the main body 1102 of the page pressing mechanism. In this way, during the pressing process, the situation where only the additional pressing part 1103 presses the scanning object can be achieved, so that the influence of the pressing mechanism 110 on imaging can be minimized as much as possible.

[0068] According to a specific implementation manner of an embodiment of the present disclosure, the edge detection device 1101 is a plurality of photosensitive sensors, and the plurality of photosensitive sensors are arranged on a side of the main body of the page pressing mechanism that contacts the scanning object. In this way, the edges of the scanning object can be detected by the plurality of photosensitive sensors. Specifically, for example, when some photosensitive sensors can sense light while other parts do not, the approximate position of the edge of the scanning object can be determined. Because the photosensitive sensors within the range of the scanning object will be blocked.

[0069] Alternatively, the edge detection device 1101 can be a diode or a triode, and the edge position of the scanning object is determined by the resistance of the diode or triode or the resistance or current value flowing through the diode or triode. Specifically, for example, when the diode or triode is blocked by 1 / 2, its resistance value is 2 times that in the unblocked case, and when it is blocked by 1 / 3, its resistance value is 2 times that in the unblocked case. In other words, the resistance value of the diode or triode is basically linearly related to the blocked part, so its position can be determined according to the resistance value or current value.

[0070] According to a specific implementation manner of an embodiment of the present disclosure, the edge detection device 1101 further includes a light source, and the light source is configured to emit light that can trigger the edge detection device 1101. In order to conveniently trigger the edge detection device 1101 such as a diode or a triode, a light source can be additionally provided to be able to normally trigger the edge detection device 1101 during the edge detection process.

[0071] Specifically, the light source can be a visible light source, an infrared light source, etc.

[0072] According to a specific implementation manner of an embodiment of the present disclosure, a microswitch is installed on the additional pressing portion 1103, and when the additional pressing portion presses the scanning object, the microswitch can be triggered. Specifically, when the additional pressing portion 1103 presses the scanning object, in order to determine when to stop pressing, a microswitch is provided on the additional pressing portion 1103, and the position to stop pressing is determined by the microswitch.

[0073] In addition, a spring is also installed on the additional pressing portion 1103, and the spring is configured to reset the additional pressing portion 1103 when the additional pressing portion is not in contact with the scanning object.

[0074] In addition, an embodiment of the present disclosure also provides a scanning device, which includes the page pressing mechanism 110, the page turning device 108, and the image acquisition device as described above.

[0075] The page turning device 108 is configured to separate the first scanning object and the second scanning object by an angle. Specifically, the page turning module 108 can drive back and forth along the guide rail provided on the frame 105, thereby driving the scanning object to move, so that the first scanning object and the second scanning object are separated by an angle.

[0076] The image acquisition device is configured to image the first scanning object and the second scanning object that have been page turned, and convert the obtained images into electronic data.

[0077] According to a specific implementation manner of an embodiment of the present disclosure, the scanning device further includes a page separation device, which is configured to make the first scanning object and the second scanning object at least partially in a non - adhering state. Specifically, before the page turning module 108 separates the first scanning object and the second scanning object by an angle, the page separation device can be used to first make the first scanning object and the second scanning object at least partially in a non - adhering state. Specifically, the first scanning object can be bent so as to be in a non - adhering state with the second scanning object.

[0078] In addition, referring to Figure 6 , an embodiment of the present disclosure also provides a scanning method, which includes:

[0079] S401: Detect the edge position of the scanning object by using the edge detection device 1101.

[0080] S402: Perform a page separation operation on the scanning object by using the page separation device, so that the first scanning object and the second scanning object are at least partially in a non - adhering state.

[0081] S403: Press the scanning object by using the page pressing mechanism 110 so that the main body 1102 of the page pressing mechanism presses the scanning object.

[0082] S404: Move the scanning object so that at least a part of the additional pressing portion 1103 presses the scanning object. By moving the scanning object so that at least a part of the additional pressing portion 1103 presses the scanning object, the space occupied by the pressing mechanism main body 1102 on the scanning object can be reduced, and further, the shadow generated by the pressing mechanism main body 1102 on the scanning object due to projection or the like can be reduced. In this case, it is required that the height of the additional pressing portion 1103 is lower than the height of the pressing mechanism main body 1102, so that the generation of the shadow can be reduced.

[0083] S405: Image the first scanning object and the second scanning object by using the image acquisition device.

[0084] According to a specific implementation manner of an embodiment of the present disclosure, the method includes moving the scanning object so that the scanning object is away from the pressing mechanism main body before performing the paging operation on the scanning object by using the paging device. This is because there is the additional pressing portion 1103. If the length of the additional pressing portion 1103 is too long, interference between the paging device and the additional pressing portion 1103 may occur during the paging process. At this time, by moving the scanning object so that the scanning object is away from the pressing mechanism main body, this situation can be prevented from occurring.

[0085] As described above, the above is only the specific implementation manner of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any change or replacement that can be easily thought of by those skilled in the art within the technical scope disclosed by the present disclosure should be covered by the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
