[0033] First embodiment

[0034] See also Figure 1 to Figure 7The present invention provides an image processing device, including a base 101, a support plate 102, a page turning component 103, a stabilizing component 104 and a scanning component 105, wherein the support plate 102 is fixedly connected to the base 101 and is located at the top of the base 101, the page turning component 103 includes a rotating rod 106, a driving member 107 and an adsorption rod 108, the rotating rod 106 is rotatably arranged on the base 101, the driving member 107 is used to drive the rotating rod 106 to rotate, the adsorption rod 108 is arranged on the rotating rod 106, the stabilizing component 104 includes a control rod 109 and a contact block 110, the control rod 109 is rotatably arranged on the support plate 102, the contact block 110 is arranged on the top of the control rod 109, and the scanning component 105 is arranged on the top of the support plate 102.

[0035] In this embodiment, the base 101 is the basic part of the whole device. The base 101 not only provides stable support, but also contains the electrical control system and other auxiliary facilities required by the device. Its design takes into account durability and portability, and can adapt to the use requirements in different environments. The support plate 102 is fixed to the base 101 by a solid connection and is located above the base 101. It is used to provide enough space to accommodate documents of different sizes. The page turning component 103 is to realize automatic page turning, which greatly improves the speed and efficiency of document processing. It consists of three parts: a rotating rod 106, a driving member 107 and an adsorption rod 108. The rotating rod 106 is installed on the base 101 and can rotate freely; the driving member 107 is responsible for providing power so that the rotating rod 106 can rotate at a preset speed and direction; the adsorption rod 108 is installed on the rotating rod 106 and can adsorb and turn the page as needed. This design not only ensures the smoothness of the page turning action, but also avoids damage to the document. In order to ensure the stability and safety of the document during the page turning process, the device is equipped with a set of stabilization components 104. The component mainly includes a control rod 109 and a contact block 110. The control rod 109 is rotatably mounted on the support plate 102, and the contact block 110 is located at the top of the control rod 109. When the device is working, the contact block 110 can be slightly pressed on the document to prevent the document from moving or offsetting due to external factors, thereby ensuring the scanning quality. The scanning component 105 is located on the top of the support plate 102 and is one of the core parts of the entire device. It converts documents into digital images. The scanning component 105 is usually equipped with a high-resolution camera or other optical sensor, as well as a corresponding light source to ensure that clear and high-quality images can be obtained even when turning pages quickly. In addition, the scanning component 105 may also have functions such as color correction and edge detection to further improve the effect of image processing.

[0036] In summary, this image processing device realizes the automation and intelligence of document processing, which not only improves work efficiency but also protects precious documentary materials from damage.

[0037] The image processing device further includes a limiting plate 111 , which is fixedly connected to the supporting plate 102 and is located on one side of the supporting plate 102 .

[0038] The limit plate 111 is fixedly connected to the support plate 102 and is located on one side of the support plate 102. Its main function is to provide a clear positioning reference point when placing the document, ensuring that the position of the document is consistent each time, thereby improving the accuracy and consistency of scanning. The design of the limit plate 111 takes into account documents of different sizes and shapes, ensuring a wide range of applicability.

[0039] The adsorption rod 108 includes a lifting cylinder 112, a lifting rod 113, a return spring 114 and an adsorption rod body 115. The lifting cylinder 112 is fixed on the rotating rod 106. The lifting rod 113 is connected to the output end of the lifting cylinder 112. Multiple suction cups are arranged on the adsorption rod body 115. The adsorption rod body 115 is fixed on the lifting rod 113. The return spring 114 is arranged between the lifting cylinder 112 and the lifting rod 113.

[0040] The lifting cylinder 112 is fixed on the rotating rod 106 and serves as a power source for the vertical movement of the adsorption rod 108. Through the change of air pressure, the lifting cylinder 112 can push or pull the lifting rod 113 connected to its output end, thereby adjusting the height position of the adsorption rod 108. This design allows the adsorption rod 108 to flexibly contact or leave the document surface according to actual needs, adapting to different operating requirements.

[0041] The lifting rod 113 is connected to the output end of the lifting cylinder 112, and directly drives the adsorption rod body 115 to move up and down. The design of the lifting rod 113 ensures the stability and accuracy of the movement of the adsorption rod 108, and avoids document damage or scanning errors caused by unstable movement.

[0042] The return spring 114 is disposed between the lifting cylinder 112 and the lifting rod 113, and is mainly used to quickly restore the adsorption rod 108 to its initial position to separate from the document when the lifting cylinder 112 stops working, so as to facilitate scanning operations.

[0043] The suction rod body 115 is fixed on the lifting rod 113, and multiple suction cups are arranged on it. These suction cups can adjust the suction force according to the material and thickness of the document to ensure that the page turning action is completed without damaging the document. The design of multiple suction cups improves the uniformity and reliability of suction, and even thin paper can be safely handled.

[0044] The adsorption rod 108 further includes an adjustment ring 116 , which is threadedly connected to the rotating rod 106 and is located on one side of the lifting rod 113 .

[0045] The adjustment ring 116 is threadedly connected to the rotating rod 106 and is located on one side of the lifting rod 113. By rotating the adjustment ring 116, the movable distance of the suction rod 108 relative to the rotating rod 106 can be fine-tuned to accommodate documents of different sizes. This function is particularly important for processing documents of special shapes or textures.

[0046] The adsorption rod 108 further includes an air outlet plate 117 and a rotating roller 118 . The air outlet plate 117 is disposed on one side of the adsorption rod body 115 , and the rotating roller 118 is rotatably disposed on one side of the air outlet plate 117 .

[0047] The air outlet plate 117 is disposed on one side of the suction rod body 115 , and is mainly used to blow the pages through the air outlet plate 117 after the suction rod 108 is lifted, so as to avoid pages sticking together, thereby helping to turn the pages of the document smoothly.

[0048] The rotating roller 118 is rotatably disposed on one side of the air outlet plate 117 and cooperates with the adsorption rod body 115 to disturb the pages on the other side through friction, so that the occurrence of page adhesion can be further reduced.

[0049] The rotating roller 118 is provided with a plurality of grooves 119 , and the airflow ejected from the air outlet plate 117 acts on the grooves 119 to push the rotating roller 118 to rotate.

[0050] The rotating roller 118 is provided with a plurality of grooves 119, which are evenly distributed along the circumference of the rotating roller 118. Each groove 119 has a certain depth and shape to ensure that the airflow can effectively act inside it. When the airflow ejected from the air outlet plate 117 reaches these grooves 119, the airflow will generate thrust inside the grooves 119, pushing the rotating roller 118 to rotate around its axis.

[0051] The scanning assembly 105 includes a scanning head 120 and an illumination lamp 121 . The scanning head 120 is fixed on the top of the supporting plate 102 , and the illumination lamp 121 is disposed on one side of the scanning head 120 .

[0052] The scanning head 120 is one of the core components of the entire device and is fixed on the top of the support plate 102. It is equipped with a high-resolution camera or other optical sensor that can capture every detail of the document. The design of the scanning head 120 takes into account the requirements of fast scanning and high precision, and can complete high-quality image acquisition in a short time. In addition, the scanning head 120 also has an autofocus function, which can automatically adjust the focus according to the distance and thickness of the document to ensure that a clear image can be obtained every time it is scanned.

[0053] The illuminator 121 is disposed on one side of the scanning head 120 to provide sufficient light source. The illuminator 121 generally adopts an LED light source, which has the characteristics of low power consumption, long life and high brightness. It can evenly illuminate the document surface, eliminate shadows and reflections, and ensure that the brightness and contrast of the scanned image are optimal. The design of the illuminator 121 also takes energy saving and environmental protection into consideration, and can automatically turn off when not in use to reduce energy consumption.

[0054] The contact block 110 includes a contact block body 122, an auxiliary plate 123, a movable plate 124, an auxiliary spring 125 and a support roller 126. The movable plate 124 is slidably arranged on the contact block body 122, the support roller 126 is arranged on the movable plate 124, the auxiliary spring 125 is arranged between the contact block body 122 and the movable plate 124, and the auxiliary plate 123 is rotatably arranged on the contact block body 122 and is located on one side of the movable plate 124.

[0055] The contact block body 122 is the main frame of the contact block 110 and provides a foundation for mounting other components. The contact block body 122 is usually made of high-strength material to ensure its stability and durability in long-term use.

[0056] The movable plate 124 is slidably disposed on the contact block body 122 and can freely move on the guide rail of the contact block body 122. The design of the movable plate 124 allows it to be fine-tuned according to the thickness and shape of the document, ensuring that the contact block 110 can always be in close contact with the document surface.

[0057] The support roller 126 is disposed on the moving plate 124 and is used to contact the document surface. The support roller 126 is usually made of a soft and wear-resistant material to reduce the wear on the document. The design of the support roller 126 also takes into account the rolling stability and quiet effect to ensure that no additional noise is generated during the document processing.

[0058] The auxiliary spring 125 is arranged between the contact block body 122 and the moving plate 124 to provide elastic support. When the thickness of the document changes, the auxiliary spring 125 can automatically adjust the position of the moving plate 124 to ensure that the support roller 126 always maintains appropriate contact pressure with the document surface. This not only improves the stability of the contact, but also reduces the document damage caused by uneven pressure.

[0059] When in use, the control plate rotates to drive the support roller 126 of the contact block 110 to contact the page, and then continues to press down the moving plate 124, so that the auxiliary plate 123 rotates after contacting the page to stretch the page, thereby avoiding wrinkles on the page after turning the page.

[0060] The contact block 110 further includes a support spring 127 , and the support spring 127 is disposed between the auxiliary plate 123 and the contact block body 122 .

[0061] The support spring 127 provides downward pressure to the auxiliary plate 123 so that the auxiliary plate 123 can better maintain contact with the page.

[0062] The contact block 110 further includes a rubber block 128 . The rubber block 128 is fixedly connected to the contact block body 122 and is located on one side of the contact block body 122 .

[0063] The rubber block 128 is fixedly connected to the contact block body 122 and is located on one side of the contact block body 122. The main function of the rubber block 128 is to increase the friction between the contact block 110 and the document surface to prevent the document from sliding during processing. The rubber block 128 is usually made of a material with a high friction coefficient to ensure that it can play a good anti-slip effect on documents of different materials.

[0064] The stabilizing assembly 104 also includes a push rod 129, a pushing block 130 and a second cylinder 131. The push rod 129 is slidably disposed on the support plate 102. The pushing block 130 is slidably disposed on one side of the push rod 129. The output end of the second cylinder 131 is connected to the pushing block 130. A rack 132 is disposed on the push rod 129. A gear 133 is disposed on the control rod 109. The gear 133 is meshed with the rack 132.

[0065] The push rod 129 is slidably disposed on the support plate 102 and can move freely on the guide rail of the support plate 102. The design of the push rod 129 allows the position of the push rod 129 to be adjusted as needed to accommodate documents of different sizes and shapes.

[0066] The pushing block 130 is slidably disposed on one side of the push rod 129 and is used to push the push rod 129 to slide.

[0067] The output end of the second cylinder 131 is connected to the push block 130 to provide power for the push block 130. The design of the second cylinder 131 ensures that the movement of the push block 130 is stable and controllable, and the pushing force and speed can be adjusted as needed.

[0068] The push rod 129 is provided with a rack 132, and the control rod 109 is provided with a gear 133, and the gear 133 meshes with the rack 132. This design allows the rotation of the control rod 109 to directly drive the movement of the push rod 129, thereby achieving precise control of the document. The coordinated use of the rack 132 and the gear 133 not only improves the efficiency of the transmission, but also ensures the stability and accuracy of the movement.

[0069] Second embodiment

[0070] See also Figure 8 The present invention also provides a method for using an image processing device, comprising:

[0071] S201: Spread out the book and place it on the support plate 102;

[0072] First, make sure that the image processing device has been properly installed and connected to the power supply, and all components are in normal working condition. Gently open the book to be processed and place it flat on the support plate 102. Make sure that the spine of the book is aligned with the positioning mark on the support plate 102 to facilitate the accurate performance of subsequent operations.

[0073] S202: Start the driving member 107 to drive the rotating rod 106 to approach the book page;

[0074] The driving member 107 is activated through the operation interface or control button of the device. The driving member 107 will start to work, driving the rotating rod 106 to move toward the book page. The movement of the rotating rod 106 is observed to ensure that it can accurately approach the book page, but does not over-press the book to avoid damage. When the rotating rod 106 reaches the predetermined position, its relative position with the book page is checked to ensure that the suction rod 108 can smoothly contact the book page.

[0075] S203: start the suction rod 108 to suck up the book page by negative pressure, and then start the driving member 107 to drive the book page to rotate and turn the page;

[0076] Start the negative pressure system of the suction rod 108, and the suction cup on the suction rod 108 will suck up the book pages through negative pressure. Make sure that the contact surface of the suction cup and the book page is fully in contact to obtain a good adsorption effect. Start the driving member 107 to drive the rotating rod 106 and the suction rod 108 to rotate together, so as to realize the turning of the book pages. During the page turning process, pay attention to the movement of the book pages to ensure that the page turning action is smooth and without jamming. According to the thickness and material of the book, adjust the rotation speed of the driving member 107 appropriately to ensure that the page turning process is both fast and safe.

[0077] S204 controls the control rod 109 to rotate so as to drive the contact block 110 to level the turned pages;

[0078] The control rod 109 is activated through the operation interface or the control button to start rotating. The rotation of the control rod 109 drives the contact block 110 to move and flatten the pages after turning. The support roller 126 and the rubber block 128 on the contact block 110 will apply appropriate pressing force to the pages to ensure that the pages are flat. The size of the pressing force can be controlled by adjusting the tension of the auxiliary spring 125 and the support spring 127. Observe the flatness of the pages to ensure that there are no wrinkles or warps.

[0079] S205 scans the book page through the scanning component 105 .
