It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

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.

[0042] 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.

[0043] The page-turning mechanism and page-turning transmission method of this application will now be described in detail with reference to the accompanying drawings.

[0044] Please refer to the above as well. Figure 1 and Figure 2 The page-turning mechanism 100 provided in this application includes a frame 10 on one side for placing the document to be turned, two bottom transmission structures 20 disposed on opposite sides of the frame 10, two pre-pressing structures 40 respectively fixed on the two bottom transmission structures 20 for rubbing contact with the paper to be turned, and a movable base 50 disposed on the side of the frame 10 away from the side where the document is placed.

[0045] Each bottom transmission structure 20 is equipped with a rotatable swing arm 30 for page turning. The pre-pressing structure 40 and the swing arm 30, both mounted on the same bottom transmission structure 20, are distributed sequentially from the side to be turned towards the side after the page is turned. Each pre-pressing structure 40 is connected to a base 50, and racks 51, which are respectively connected to the teeth of the two bottom transmission structures 20, are provided on opposite sides of the base 50. The movable base 50 is used to drive each pre-pressing structure 40 thereon to move, and the movable base 50 is used to drive the bottom transmission structure 20 to rotate via the racks 51 thereon, thereby causing the swing arm 30 and the movable pre-pressing structure 40 to rotate simultaneously.

[0046] It is worth noting that the two bottom drive structures 20 are located on both sides of the document to be turned on the frame 10. When the document is in the open state on the frame 10, the two bottom drive structures 20 are located at the binding line of the open document. The binding line can divide the paper of the open document into the paper on the side to be turned and the paper on the side after turning.

[0047] Combined with reference Figures 1 to 4Each bottom transmission structure 20 includes a connecting shaft 21, a turbine 22, a worm gear 23, and a gear 24. Specifically, the connecting shaft 21 and the base 50 are located on the same side of the frame 10 and its cross-section is D-shaped; the turbine 22 is sleeved on the connecting shaft 21 and has a D-shaped through hole in the middle that matches the connecting shaft 21; the worm gear 23 is located on one side of the connecting shaft 21, and the middle part of the worm gear 23 meshes with the turbine 22, and a gear 24 and a rocker arm 30 are respectively provided at both ends.

[0048] It is worth noting that the page-turning mechanism 100 needs to operate synchronously: the pre-pressing structure 40 frictionally causes the paper to be turned to arch, and during the process of the pre-pressing structure 40 lifting the page, it simultaneously rotates outward relative to the paper and moves away from the paper. At the same time, the swing arm 30 rotates synchronously, ultimately turning the arched paper to the other side. The specific page-turning process is as follows: the connecting shaft 21 set on the base 50 moves with the base 50, and the moving connecting shaft 21 drives the pre-pressing structure 40 to move, causing friction to arch the paper; at the same time, the moving base 50 causes the gear 24 meshing with the rack 51 to rotate, thereby causing the worm 23 to rotate as well, and the swing arm 30 on the worm 23 also rotates as well. Since the worm 23 and the worm wheel 22 on the connecting shaft 21 are meshed, the worm wheel 22 rotates, thus giving the connecting shaft 21 a rotational driving force. As mentioned above, when the meshing of the rack 51 and the gear 24, and the meshing of the worm 23 and the worm wheel 22 are achieved synchronously, the movement and rotation of the connecting shaft 21 are also synchronous. However, to ensure smooth page turning with the lever 30, it is generally set in a fixed position and rotated to turn the pages. In this application, the lever 30 is set to a fixed preset position, which is the connection point between the two sides of the opened document, i.e., the aforementioned binding line. The lever 30 then turns the pages by rotating within this preset position. Simultaneously, during the movement of the connecting shaft 21, it is necessary to ensure that the worm gear 23 meshing with the turbine 22 on the moving connecting shaft 21 does not undergo the same displacement change as the connecting shaft 21. That is, to ensure that the turbine 22 on the connecting shaft 21 and the worm gear 23 meshing with it do not change displacement, since the lever 30 is mounted on the worm gear 23, if the worm gear 23 causes the lever 30 to change displacement, the position of the lever 30 will change, making it impossible to guarantee that the lever 30 is in the appropriate position to turn the pages, thus causing the page turning to fail.

[0049] To address the aforementioned issues, this application proposes a design where the cross-section of the rotating connecting shaft 21 is D-shaped, and the turbine 22 also has a D-shaped through hole in its center that matches the connecting shaft 21. Thus, the cooperation between the D-shaped through hole and the D-shaped connecting shaft 21 ensures that the moving connecting shaft 21 will not cause the turbine 22 to change displacement, thereby preventing the worm gear 23, which is connected to the turbine 22, from changing displacement. Ultimately, this also prevents the rocker arm 30 on the worm gear 23 from changing displacement, and the D-shaped connecting shaft provides a rotational positioning function.

[0050] Refer to together Figure 5 Each pre-pressing structure 40 includes a U-shaped pre-pressing plate 41 and a pressing structure 42 for frictional contact with the paper. The pressing structure 42 is disposed on one end of the pre-pressing plate 41, and the other end of the pre-pressing plate 41 is disposed on the connecting shaft 21. A D-shaped through hole matching the cross-section of the connecting shaft 21 is formed on the other end of the pre-pressing plate 41, and the connecting shaft 21 passes through the D-shaped through hole. Thus, the pre-pressing plate 41 rotates with the connecting shaft 21 to movably hold the side of the frame 10, and does not move during rotation without any displacement change with the connecting shaft 21.

[0051] It is worth noting that before turning the page, all components are in the initial page-turning position: the opened document is placed on the frame 10, the pre-pressing structure 40 contacts and presses down on the paper to be turned at the side of the frame 10, the swing arm 30 is in the zero rotation position for page turning, the U-shaped pre-pressing plate 41 is held on the side of the frame 10, and the pressing structure 42 on the pre-pressing plate 41 presses down on the paper perpendicularly above it. During page turning, the base 50 moves from the first position to the side to be turned and then to the second position, achieving one page turn. Specifically, the pressing structure 42, which moves with the base 50, can rub the paper to lift it and rotate away from the paper after lifting it, following the rotation of the pre-pressing plate 41 on the connecting shaft 21. The swing arm 30 rotates to achieve page turning. After page turning, the base 50 moves back to the first position in the opposite direction from the second position, and the swing arm 30 returns to the zero position. During this process, the movement of each component is the opposite of that during page turning.

[0052] In one embodiment, gear 24 has a module of 0.5 and 25 teeth. The transmission ratio between rack 51 and gear 24 is 1:1, meaning that gear 24 rotates one revolution when rack 51 moves 25 teeth. Turbine 22 has 15 teeth, and worm 23 has 1 head. The transmission ratio between worm and turbine is 1:15, so worm 22 rotates 24° when worm 23 rotates one revolution. During one page-turning process, connecting shaft 21, turbine 22 on connecting shaft 21, and pre-pressure plate 41 on connecting shaft 21 rotate approximately 24 degrees. Too small a rotation angle may cause the pre-pressure structure 40 to obstruct the page turning, while too large a rotation angle is unnecessary; approximately 24 degrees or slightly greater is acceptable.

[0053] Furthermore, the pressing structure 42 includes a slide rod 421, a silicone element 422, and a spring 423. Specifically, the slide rod 421 can movably pass through one end of the pre-press plate 41 and extend into the U-shaped area of ​​the pre-press plate 41. The end of the slide rod 421 extending into the U-shaped area is provided with a silicone element 422 for frictional contact with the paper to be turned. The spring 423 is sleeved on the slide rod 421, with one end of the spring 423 disposed on the slide rod 421 and the other end disposed on the silicone element 422.

[0054] Understandably, when placing the document, the force exerted by the document causes the slide bar 421 to move on the pre-pressure plate 41, while the spring 423 keeps the silicone part 422 pressing down on the paper. The movable slide bar 421 and spring 423 allow the pressing structure 42 to adapt to documents of different thicknesses to be turned.

[0055] like Figures 1 to 3 As shown, the frame 10 includes a base plate 11 for placing documents and two side plates 12 connected to opposite sides of the base plate 11. Each side plate 12 has a first receiving hole 13 and a second receiving hole 14 arranged side-by-side and penetrated by a connecting shaft 21. The first receiving hole 13 and the second receiving hole 14 expose the edge of the base plate 11 connected to the side plate 12. A worm gear 23 passes through the first receiving hole 13 on one side plate 12 in the direction of the vertical stacking of the base 50 and the frame 10. The two ends of the worm gear 23 are respectively provided with a swing arm 30 for page turning and a gear 24 connected to a rack 51.

[0056] Furthermore, the first receiving hole 13 and the second receiving hole 14 on the same side plate 12 are sequentially distributed in the direction from the side to be turned to the side after the page is turned. The connecting shaft 21 is also fitted with two rear pressing members 60 located at the first receiving hole 13 and the second receiving hole 14 respectively. The two rear pressing members 60 on the same connecting shaft 21 are used to press down the paper on the side to be turned and the paper on the side after the page is turned, respectively. Each rear pressing member 60 is fitted onto the end of the connecting shaft 21 and has a D-shaped through hole that mates with the connecting shaft 21.

[0057] It is worth noting that, similar to the aforementioned turbine 22, the D-shaped through-hole design restricts the rear pressure member 60 on the connecting shaft 21 from moving with the connecting shaft 21, as it only rotates with the connecting shaft 21. Thus, before page turning, the two rear pressure members 60 can press down on the side of the page to be turned and the side after the page is turned, respectively. During page turning, the rear pressure member 60 rotates outward relative to the paper with the connecting shaft 21. After page turning, the rear pressure member 60 rotates in the opposite direction with the connecting shaft 21, thus pressing down on the side of the page to be turned and the side after the page is turned. Therefore, if the paper after page turning is not completely flat on the base plate 11 due to the rotation of the swing arm 30, the rear pressure member 60 can provide further downward pressure.

[0058] Furthermore, a central hole 52 is provided in the middle of the base 50, and a driving device for moving the base 50 is provided in the area of ​​the central hole 52. Another rack is also provided on the base 50, located in the central hole 52. The driving device may include a motor and another gear that is toothed with the rack. The motor drives the gear to rotate, and the meshing action of the rack and the gear drives the base 50 to move.

[0059] It is worth noting that the stacked frame 10 and base 50, the bottom transmission structure 20 on both sides of the base 50, the first receiving hole 13 and the second receiving hole 14 on the frame 10, and the central hole 52 in the middle of the base 50, all contribute to the compact and well-planned spatial arrangement of the components of the page-turning mechanism 100, which helps to save space.

[0060] The page-turning scanning device provided in this application embodiment includes a scanner disposed on the side of the base 10 for placing documents and the aforementioned page-turning mechanism 100.

[0061] The scanner is positioned above the document to be scanned, with its lens facing the side of the paper to be turned. The scanner is used to scan the side of the paper used to turn the document. The page-turning mechanism 100 is used to automatically turn the pages of the paper scanned by the scanner.

[0062] Please refer to Figure 6 This application embodiment also provides a page-turning transmission method based on the above-mentioned page-turning mechanism, which includes the following steps S100 to S400.

[0063] Step S100: Drive the base with racks on both sides to move the page-turning side towards the side after the page is turned.

[0064] Step S200: The moving base drives the pre-pressing structure connected to the base to move, and the moving pre-pressing structure rubs and arches the paper on the side to be turned.

[0065] Step S300: Drive the bottom transmission structure to rotate by moving the rack on the base in a meshing manner.

[0066] During step S300, steps S400 and S500 are performed simultaneously.

[0067] Step S400: The rotating bottom transmission structure drives the connected pre-compression structure to rotate, gradually moving away from the arched paper.

[0068] Step S500: The rotating bottom transmission structure drives the swing arm on it to rotate, turning the arched paper to the side after the page is turned.

[0069] In one embodiment of the application, the movement of the pre-compression structure connected to the base by moving the base includes: moving the connecting shaft disposed on the base by moving the base, so as to move the pre-compression structure disposed on the connecting shaft.

[0070] In another embodiment, the method of driving the pre-pressure structure on the bottom transmission structure on opposite sides of the frame for holding documents to rotate gradually away from the arched paper by a rack on a movable base in an engaging manner includes:

[0071] The rotating rack drives the gear meshing with it to rotate.

[0072] The worm gear with the gear on its end is rotated by rotating the gear.

[0073] The rotating worm drives the turbine meshing with the middle of the worm to rotate.

[0074] The rotating turbine drives the connecting shaft on which it is mounted to rotate, thereby causing the preload structure mounted on the connecting shaft to rotate.

[0075] In another embodiment of the application, the method of rotating the bottom transmission structure to drive the swing arm thereon to rotate, thereby turning the arched paper to the side after the page has been turned, is as follows:

[0076] The rotating worm gear drives the pendulum on the worm gear to rotate, thereby turning the arched paper to the side after the page is turned.

[0077] The pre-pressing structure and the swing arm, which are set on the same bottom transmission structure, are distributed in sequence from the side to be turned to the side after the page is turned.

[0078] 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.
