Description

Technical Field

[0001] The present application belongs to the technical field of document page turning scanning, and more specifically, relates to an adaptive gear-linked page turning scanning mechanism. Background Art

[0002] The ID card scanning device integrates precision mechanical design, intelligent recognition algorithms, and automated control technology to efficiently and accurately scan and store information on a wide range of documents. Using built-in high-precision sensors and image processing technology, the device accurately identifies edges and specific markings on documents, then drives a mechanical mechanism to automatically flip pages for continuous scanning.

[0003] Although ID page-turning scanning devices play an important role in digital office, there are still some problems that need to be solved in actual application. Among them, the most prominent one is the unstable page turning caused by the thickness of the ID card and the different hardness of the page.

[0004] Specifically, different documents vary in thickness and material, such as soft paper and hard card stock. For example, the thickness of the same document varies depending on the number of pages. During the automatic page turning process, varying the number of pages in a document will result in different heights of the page being held. Furthermore, if the suction cup's angle remains fixed, the excessive suction force on soft paper could cause the paper to bend, damaging the document and affecting the scanning experience. For hard paper or card stock, if the angle between the suction cup and the page is less than 90 degrees, the suction cup's suction force may be insufficient to maintain the paper's stability, causing it to fall off during the turning process.

[0034] 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 the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0035] Please also refer to Figures 1 to 4 , the adaptive gear-linked page-turning scanning mechanism provided in the embodiment of the present application is now described.

[0036] The adaptive gear-linked page turning and scanning mechanism includes a pair of side substrates 10 , and a first gear 20 , a second gear 30 , and a page suction mechanism 40 disposed between the pair of side substrates 10 .

[0037] Specifically, the first gear 20 is provided with a toggle member 21 and a page-turning member 22; the second gear 30 is arranged parallel to the first gear 20 and is provided with a page-pressing member 31; the page-sucking mechanism 40 includes a swing arm 41 and an adsorption member 42, and the swing arm 41 is provided with a reciprocating motion mechanism 43 and an elastic reset member 44, the adsorption member 42 is movably arranged with the reciprocating motion mechanism 43, and the elastic reset member 44 is connected to the reciprocating motion mechanism 43.

[0038] The adsorption member 42 can adsorb the document page, the first gear 20 and the second gear 30 rotate in the same direction, and when the toggle member 21 toggles the swing arm 41 to move, the reciprocating mechanism 43 can compress the elastic reset member 44.

[0039] Understandably, please refer to Figure 4 In the initial state, the document to be turned over is located below the page suction mechanism 40. Since the adsorption member 42 and the reciprocating motion mechanism 43 are movably arranged, and the elastic reset member 44 is connected to the reciprocating motion mechanism 43, the page suction mechanism 40 can adapt to the thickness of the document, so that the reciprocating motion mechanism 43, the elastic reset member 44 and the swing arm 41 are in the initial state, ensuring that the adsorption member 42 is vertically adsorbed on the document page to improve the stability of the document adsorption.

[0040] As you turn the pages, please also refer to Figure 5 The first gear 20 and the second gear 30 rotate in the same direction, and the second gear 30 drives the toggle member 21 to rotate synchronously. When the toggle member 21 drives the swing arm 41 to move upward, the adsorption member 42 will be simultaneously subjected to the pulling force F1 of the swing arm 41 and the pulling force F2 of the document page, so that the reciprocating motion mechanism 43 will compress the elastic reset member 44. At the same time, the adsorption member 42 will adaptively follow the synchronous rotation of the document page to ensure that the adsorption member 42 is always vertically adsorbed on the document page, so as to further improve the stability of the document adsorption.

[0041] Once the ID page is sucked up, the pages are separated. Since the first gear 20 is also equipped with a page-turning member 22, the page-turning member 22 enters between the separated pages as it rotates with the first gear 20. At this point, the suction member 42 disengages from the ID page. Under the internal force of the elastic return member 44 and its own inertia, the suction member 42 swings away from the ID page. Simultaneously, the page-turning member 22 continues to rotate, completing the page-turning process. After the toggle member 21 leaves the swing arm 41, the reciprocating mechanism 43, the elastic return member 44, and the swing arm 41 quickly reset and adapt to the thickness of the ID after the page is turned, ensuring that the suction member 42 is vertically attached to the next page.

[0042] Please also refer to Figure 6 , and because the second gear 30 is arranged in parallel with the first gear 20 and is provided with a page pressing member 31, and the first gear 20 and the second gear 30 rotate in the same direction, the page pressing member 31 can further press the turned page of the document, so that the turned page of the document remains in a stable state, avoiding the page from flipping and resetting.

[0043] In another embodiment, the adaptive gear-linked page-turning scanning mechanism further includes a code scanning device (not shown), which is disposed on the side substrate 10 and is used to scan the document page after turning the page to obtain document information.

[0044] It's worth noting that the pair of side substrates 10 are spaced apart and arranged parallel to each other, forming a basic structure that facilitates the installation of other components. All gear structures described in this application can be arranged in pairs, with the two gears coaxially and symmetrically arranged between the pair of side substrates 10. The ends of the rotating axis can be located on the pair of side substrates 10. The suction element 42 can be a suction cup or nozzle connected to a vacuum pump, designed to absorb the document page.

[0045] Therefore, the adaptive gear-linked page-turning scanning mechanism provided by this application has the following beneficial effects compared with the prior art:

[0046] 1. The page suction mechanism 40 can adapt to the thickness of the document, so that the reciprocating mechanism 43, the elastic return member 44 and the swing arm 41 are in the initial state, ensuring that the suction member 42 is vertically adsorbed on the document page, thereby improving the stability of the document adsorption;

[0047] 2. During the page turning process, the reciprocating motion mechanism 43 will compress the elastic reset member 44, and at the same time, the adsorption member 42 will adaptively rotate synchronously with the document page to ensure that the adsorption member 42 is always vertically adsorbed on the document page, so as to further improve the stability of the document adsorption.

[0048] 3. After the ID page is sucked up, the suction member 42 can swing away from the ID page under the internal force of the elastic reset member 44 and its own inertia. At the same time, the page turning member 22 continues to rotate to complete the page turning process of the ID page. The page will not be bent during the entire page turning process, and it can adapt to soft pages and hard pages (such as ID cover, passport).

[0049] 4. The power of the entire page turning process is entirely derived from the rotation of the second gear 30, which improves the cyclic continuity of actions such as adsorption, dialing, page turning, and resetting.

[0050] In another embodiment of this application, please refer to Figure 7The adaptive gear-linked page-turning scanning mechanism also includes a third gear 50, a fourth gear 60, a fifth gear 70, a sixth gear 80, a brush wheel 90 and a power assembly 91. The third gear 50 is respectively engaged with the first gear 20 and the second gear 30. The fourth gear 60 and the first gear 20 are coaxially movable through a transfer bearing 92. The fifth gear 70 is coaxially fixed with the second gear 30. The fourth gear 60 is engaged with the fifth gear 70. The sixth gear 80 is engaged with the fourth gear 60. The brush wheel 90 is coaxially fixed with the sixth gear 80. The brush wheel 90 is located on one side of the page suction mechanism 40. The power assembly 91 is connected to the rotating shaft of the second gear 30.

[0051] It can be understood that, under the drive of the power assembly 91, since the third gear 50 is respectively engaged with the first gear 20 and the second gear 30, the first gear 20 and the second gear 30 can rotate in the same direction; since the fourth gear 60 and the first gear 20 are coaxially movably arranged through the adapter bearing 92, the fifth gear 70 is coaxially fixedly arranged with the second gear 30, and the fourth gear 60 is engaged with the fifth gear 70, the fourth gear 60 and the fifth gear 70 rotate in opposite directions, and then the fourth gear 60 can drive the sixth gear 80 and the brush wheel 90 to rotate in the direction opposite to the page flipping direction, so as to avoid the occurrence of multiple pages being flipped at one time due to page adhesion.

[0052] In this way, based on the multi-stage gear linkage structure of this embodiment, coaxial and unidirectional rotation (the second gear 30 and the fifth gear 70) and coaxial reverse movement (the first gear 20 and the fourth gear 60) can coexist, meeting the rotation direction requirements of different actions. At the same time, all power is derived from the power component 91 and transmitted to each moving part in turn through the multi-stage gear linkage, thereby improving the synchronization and coordination of actions such as adsorption, page turning, dialing, pressing, and anti-sticking connection.

[0053] In addition, one end of the swing arm 41 can be movably disposed on the central axis of the third gear 50 via a bearing, so that the swing arm 41 and the third gear 50 are coaxial to simplify the structure.

[0054] For further information, please also refer to Figure 7 The first gear 20 and the second gear 30 have the same pitch circle, and the third gear 50 and the fourth gear 60 have the same pitch circle.

[0055] It can be understood that when gears with the same pitch circle are engaged, the tooth pitch and tooth shape are completely matched, which can further achieve smooth power transmission, reduce vibration and noise during gear meshing, and improve transmission stability and reliability.

[0056] Furthermore, the power assembly 91 includes a motor and a reducer, and the motor is connected to the rotating shaft of the second gear 30 through the reducer.

[0057] In another embodiment of this application, please refer to Figure 3 The swing arm 41 is provided with an arm stabilizing arc structure 45, which is a smooth structure formed by being recessed upward. The toggle member 21 controls the movement speed of the swing arm 41 by sliding in contact with the arm stabilizing arc structure 45 during the rotation process.

[0058] It is understood that the moment the toggle member 21 contacts the swing arm 41 during rotation, it will generate significant vibration, which can easily cause the suction member 42 to detach from the document page. In this embodiment, by providing a stabilizing arc structure 45 on the swing arm 41, the toggle member 21 controls the movement speed of the swing arm 41 through sliding contact with the stabilizing arc structure 45 during rotation, while gradually increasing the swing speed of the swing arm 41 and maintaining the suction stability of the suction member 42.

[0059] For further information, please also refer to Figure 6 The curvature radius of the arm stabilizing arc structure 45 is the same as the curvature radius of the motion trajectory of the toggle member 21 .

[0060] It can be understood that because the radius of curvature of the stabilizing arm arc structure 45 is the same as the radius of curvature of the motion trajectory of the toggle member 21, when the surface of the stabilizing arm arc structure 45 coincides with the motion trajectory of the toggle member 21, the swing arm 41 reaches its highest swing position and remains there for a period of time T until the toggle member 21 rotates away from the stabilizing arm arc structure 45. During the page separation process, negative pressure is formed between adjacent pages, easily lifting the next page. During this period of time T, because the swing arm 41 is stationary, this negative pressure gradually dissipates, and the lifted next page naturally falls due to gravity within this period of time T, thereby achieving automatic page separation. In this manner, until the toggle member 21 rotates away from the stabilizing arm arc structure 45, the page turning member 22 enters between the separated pages as it follows the rotation of the first gear 20, further reducing the occurrence of multiple pages being turned at once due to page sticking.

[0061] Furthermore, the shifting member 21 is a pulley.

[0062] It is understandable that the pulley can reduce friction and improve stability.

[0063] For further information, please also refer to Figure 4The page-turning member 22 includes a front section 221 and a tail section 222. The front section 221 is connected to the tail section 222. The front section 221 is a straight structure. The tail section 222 is fixed on the first gear 20. The tail section 222 is an arc structure. The center of the arc structure is located on the rotation axis of the first gear 20.

[0064] It is understandable that during the page turning process, the front section 221 of the linear structure can be aligned with the gap between the inserted pages, so that a single page can be picked up more accurately and multiple pages can be avoided from being picked up at the same time. Since the page turning member 22 itself is rotating, after the front section 221 is inserted into the gap between the pages, it will change the angle to push the page to turn, thereby avoiding damage to the page. Since the tail section 222 is an arc-shaped structure, the center of the arc structure is located on the rotating shaft of the first gear 20. Therefore, after the front section 221 picks up a single page, the tail section 222 can press down the next page that is stuck and lifted up, so that it can quickly return to its position so that the adsorption member 42 can quickly adsorb it, thereby improving the efficiency of continuous page turning.

[0065] In another embodiment of this application, please refer to Figure 4 The page pressing member 31 is a plurality of long cylinders, and the plurality of long cylinders are arranged in a ring array with the rotation axis of the second gear 30 as the center.

[0066] It can be understood that when several of the long cylinders are arranged in a circular array with the rotation axis of the second gear 30 as the center, each time the fifth gear 70 rotates a certain angle, a corresponding long cylinder will perform a page pressing operation, while also preventing the page from tilting after the page is turned.

[0067] In another embodiment of this application, please refer to Figure 3 The reciprocating motion mechanism 43 includes a guide rod 431 and a sliding member 432. One end of the sliding member 432 is slidably set on the guide rod 431 through a bearing, and the other end is movably connected to the adsorption member 42 through a bearing. The elastic return member 44 is a coil spring, and the coil spring is sleeved on the guide rod 431.

[0068] It can be understood that in the initial state, one end of the sliding member 432 is slidably set on the guide rod 431 through a bearing, and the other end is movably connected to the adsorption member 42 through a bearing. Therefore, the page suction mechanism 40 can adapt to the thickness of the document, so that the adsorption member 42 is vertically adsorbed on the document page to improve the stability of the document adsorption.

[0069] Of course, in other embodiments, the guide rod 431 can also be replaced by a guide rail, and the coil spring can also be replaced by a metal spring. In addition, a second spring is connected between the sliding member 432 and the adsorption member 42, and the second spring can accelerate the resetting of the adsorption member.

[0070] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
