[0041] The automatic page turning device and the automatic page turning method of the present application are now described in detail with reference to the accompanying drawings.

[0042] Embodiment 1:

[0043] Please refer to Figure 1 and Figure 2The automatic page turning device 100 provided in the embodiment of the present application includes a bottom plate 10, a page suction assembly 20, a page suction swing arm assembly 30, two page turning arms 40 and a driving assembly 50. Specifically, the bottom plate 10 is used to place paper certificates; the page suction assembly 20 is used to suck up the paper certificates; the page suction swing arm is arranged on the bottom plate 10 and connected to the page suction assembly 20; the two page turning arms 40 are arranged on the bottom plate 10 and are respectively arranged on opposite sides of the same surface of the bottom plate 10. The driving assembly 50 is arranged on the bottom plate 10 and connected to the page suction swing arm assembly 30 and the two page turning arms 40; the driving assembly 50 is used to drive the page suction swing arm assembly 30 to move so as to drive the page suction assembly 20 sucking the paper away from the bottom plate 10, and to drive the two page turning arms 40 to rotate in opposite directions on both sides of the sucked paper so as to turn the sucked paper.

[0044] In the automatic page turning device 100, the page sucking assembly 20 sucks up the paper document placed on the bottom plate 10, and the driving assembly 50 drives the page sucking swing arm assembly 30 to move so as to drive the page sucking assembly 20 sucking the paper away from the bottom plate 10, and at the same time, the driving assembly 50 drives the two page turning rods 40 to rotate in opposite directions on both sides of the sucked paper to turn the sucked paper. Therefore, the automatic page turning device 100 can realize the automatic page turning function, thereby helping to reduce the intensity of manual work.

[0045] Further references Figure 1 The page suction assembly 20 includes a vacuum suction cup 21 connected to the page suction swing arm assembly 30, a vacuum pump 22 located on the bottom plate 10, and a hose (not shown) connecting the vacuum suction cup 21 and the vacuum pump 22; the page suction swing arm assembly 30 is connected to the driving assembly 50, and the driving assembly 50 is used to drive the page suction swing arm assembly 30 to move so as to drive the vacuum suction cup 21 that sucks the paper to move away from the bottom plate 10.

[0046] It is worth noting that the vacuum suction cup 21 has a chamber (not shown), the chamber faces the bottom plate 10 and is connected to a hose, and the vacuum pump 22 sucks the air in the chamber through the hose, so that the vacuum suction cup 21 generates suction to suck the paper. It can be understood that after sucking the paper, as the vacuum suction cup 21 drives the paper to rise, the vacuum pump 22 gradually gives up sucking the air in the chamber, so that the page turning rod 40 can turn the page smoothly when turning the page. Furthermore, a solenoid valve for controlling the direction of airflow is provided on the bottom plate, and the hose connected to the chamber is connected to the vacuum pump through the solenoid valve. The solenoid valve can be used to control whether the suction force of the vacuum pump when sucking air is transmitted to the vacuum suction cup.

[0047] It is worth noting that before turning pages, the two page turning rods 40 are arranged in parallel on the bottom plate 10, at which time the positions of the two page turning rods 40 are the starting positions, and at which time the vacuum suction cup 21 is not driven to be lifted by the driving assembly 50, and at which time the position of the vacuum suction cup 21 is also the starting position, and at which time the vacuum suction cup 21 is spaced from the bottom plate 10. Before turning pages, the paper document placed on the bottom plate 10 is located between the vacuum suction cup 21 and the bottom plate 10 and is arranged between the two page turning rods 40.

[0048] Please refer to Figure 1 and Figure 3 The driving assembly 50 includes a motor 51 located on the base plate 10, a driving wheel 52 connected to the motor 51 and arranged on the base plate 10, a plurality of synchronous wheels 53 arranged on the base plate 10, and a synchronous belt 54 that transmits and connects the driving wheel 52 and the synchronous wheels 53; each of the page turning rods 40 is connected to one of the synchronous wheels 53, and the two synchronous wheels 53 connected to the two page turning rods 40 are respectively connected to the inner and outer sides of the synchronous belt 54.

[0049] It can be understood that since the two page turning rods 40 located on both sides of the paper document are used to turn the pages, smooth page turning can be achieved, and the paper of the test paper document to be turned is turned from one side to the other side by the two page turning rods 40. In order to achieve the coordinated page turning of the two page turning rods 40 on both sides of the paper document, the rotation directions of the two page turning rods 40 need to be opposite to each other. Since the two synchronous wheels 53 connected to the two page turning rods 40 are respectively connected to the inner and outer sides of the synchronous belt 54, when the motor 51 is used to drive the driving wheel 52 to rotate in the first direction, the driving assembly 50 is used to drive one of the page turning rods 40 to rotate in the first direction and drive the other page turning rod 40 to rotate in the second direction to achieve page turning.

[0050] Further references Figure 1 and Figure 3 A swing arm bump block 55 is provided on the synchronous belt 54 , and the page suction swing rod assembly 30 is in contact with and connected to the swing arm bump block 55 .

[0051] In this embodiment, when the synchronous belt 54 rotates, it drives the swing arm bumper 55 to move so as to push the page suction swing arm assembly 30 to move. Specifically, the page suction swing arm assembly 30 includes a support plate 32, a swing arm 31, a driving arm 33 and a lifting arm 34; the support plate 32 is fixedly arranged on the bottom plate 10 and arranged on the same side as the page turning rod 40; one end of the driving arm 33 passes through the support plate 32 and is fixedly connected to one end of the swing arm 31, the other end of the swing arm 31 is in contact with and connected to the swing arm bumper 55, the other end of the driving arm 33 is fixedly connected to the lifting arm 34, and the vacuum suction cup 21 is arranged on the lifting arm 34.

[0052] In this embodiment, when the synchronous belt 54 rotates, it drives the swing arm bumper 55 to move to promote the swing arm 31 to swing. The swinging process of the swing arm 31 drives the driving arm 33 to move to drive the lifting arm 34 to move away from or close to the base plate 10.

[0053] Further references Figure 1 and Figure 3 , the driving arm 33 includes a first rotating shaft 331, a second rotating shaft 332, a first rotating arm 333, a second rotating arm 334 and a fixed plate 335. Specifically, the fixed plate 335 is arranged on the supporting plate 32, and is arranged parallel to the first rotating shaft 331 and the second rotating shaft 332 and arranged up and down with the first rotating shaft; one end of the first rotating shaft 331 vertically penetrates the supporting plate 32 and is fixedly connected to the swing arm 31, and the other end of the first rotating shaft 331 is connected to the first rotating arm 333; the two ends of the second rotating shaft 332 are respectively hinged to the first rotating arm 333 and the second rotating arm 334; the lifting arm 34 is slidably arranged vertically with the first rotating shaft 331, penetrates the fixed arm, and the two ends are respectively fixedly connected to the second rotating arm 334 and the vacuum suction cup 21.

[0054] In this embodiment, the first rotating arm 333, the second rotating arm 334 and the second rotating shaft 332 form a moving scissor-type structure; when the swing arm collision block 55 moves, it pushes the swing arm 31 to swing, and the swing arm 31 drives the first rotating shaft to rotate during the swinging process. When the first rotating shaft 331 rotates, the end of the first rotating arm 333 away from the second rotating shaft 332 and the end of the second rotating arm 334 away from the second rotating shaft 332 are driven to approach or move away from each other. When the motor 51 drives the driving wheel 52 to rotate in the first direction, the end of the first rotating arm 333 away from the second rotating shaft 332 and the end of the second rotating arm 334 away from the second rotating shaft 332 are driven to approach each other, and the lifting arm 34 is lifted relative to the bottom plate 10, thereby driving the suction cup that sucks the paper to lift up. When the motor 51 drives the driving wheel 52 to rotate in the second direction, the situation is opposite. The first direction is clockwise, and the second direction is counterclockwise.

[0055] It can be understood that the motor 51 drives the driving wheel 52 to rotate, thereby driving the synchronous belt 54 to move, so that the swing arm collision block 55 on the synchronous belt 54 pushes the swing arm 31 to swing, and the swing arm 31 drives the first rotating shaft 331 to rotate during the swinging process. The connection relationship and special structure of the first rotating shaft 331, the first rotating arm 333, the second rotating arm 334, the second rotating shaft 332 and the lifting arm 34 make the swing of the swing arm 31 finally converted into the lifting and lowering of the lifting arm 34 relative to the base plate 10, so that the swing of the swing arm 31 is converted into the lifting and lowering of the lifting arm 34.

[0056] Furthermore, a one-way bearing is provided in each synchronous wheel 53 connected to the page-turning rod 40, and each of the page-turning rods 40 is fixedly connected to one of the one-way bearings; the rotation direction of the one-way bearing connected to the inner side of the synchronous belt 54 for transmission is a first direction, and the rotation direction of the one-way bearing connected to the outer side of the synchronous belt 54 for transmission is a second direction, and the first direction and the second direction are opposite directions to each other.

[0057] It can be understood that since the rotation direction of the one-way bearing connected to the inner side of the synchronous belt 54 is the first direction, and the rotation direction of the one-way bearing connected to the outer side of the synchronous belt 54 is the second direction; therefore, when the motor 51 drives the driving wheel 52 to rotate in the first direction, the one-way bearings in the two synchronous wheels 53 rotatably connected to the page turning rod 40 will rotate along with the synchronous wheels 53, and the page turning rod 40 will rotate to turn the pages. When the motor 51 drives the driving wheel 52 to rotate in the second direction, since the two one-way bearings will not rotate along with the synchronous wheels 53 connected thereto, the page turning rod 40 will not rotate.

[0058] Combined with reference Figure 1 and Figure 3 A photoelectric switch (not shown) is also provided on the bottom plate 10, and the photoelectric switch is used to detect that the swing arm 31 swings to the maximum position. It is worth noting that when the vacuum suction cup 21 is at the starting position, the vacuum suction cup 21 is not lifted, and the swing arm 31 is at the starting position. As the swing arm 31 swings to the maximum position, the vacuum suction cup 21 is lifted.

[0059] The automatic page turning device 100 further includes a spring 60, one end of which is disposed on the bottom plate 10 and the other end of which is fixedly connected to an end of the swing arm 31 away from the driving arm 33. When the swing arm bumper 55 on the synchronous belt 54 pushes the swing arm 31 to block the light beam emitted by the photoelectric switch during the swinging process, the motor 51 is used to drive the driving wheel 52 to rotate in the second direction; and when the motor 51 is used to drive the driving wheel 52 to rotate in the second direction, the spring 60 is used to pull the swing arm 31 back to its original position to wait for the next page turning movement, and the original position refers to the starting position of the swing arm 31.

[0060] It is worth mentioning that the motor 51 drives the driving wheel 52 to rotate in the first direction. When the swing arm 31 swings to the maximum position, the two page-turning rods 40 complete a rotation back to the starting position, and then return to the starting position to wait for the next page-turning movement. At this time, the light beam of the photoelectric switch is blocked by the swing arm 31 and the light beam is reflected by the swing arm 31 to the photoelectric switch, thereby causing the photoelectric switch to generate a photoelectric signal.

[0061] Furthermore, the motor 51, the page-turning rod 40, the driving arm 33, the support plate 32, the lifting arm 34 and the vacuum suction cup 21 are arranged on one side of the base plate 10, and the driving wheel 52, the synchronous wheel 53 and the synchronous belt 54 are arranged on the other side of the base plate 10. A movable notch is opened on one side of the base plate 10, and one end of the swing arm 31 away from the driving arm 33 passes through the movable notch and is in contact with the swing arm contact block 55, and the swing arm 31 swings in the movable notch.

[0062] In this embodiment, the motor 51, the page turning rod 40, the driving arm 33, the support plate 32, the lifting arm 34, the vacuum suction cup 21, the driving wheel 52, the synchronous wheel 53 and the synchronous belt 54 are reasonably arranged on both sides of the bottom plate 10, and the swing arm 31 is arranged to pass through the movable gap from one side of the bottom plate 10 to contact the swing arm collision block 55, so that the space on both sides of the bottom plate 10 is reasonably utilized, so that the components can be stacked up and down, which is conducive to saving space.

[0063] Embodiment 2:

[0064] Please refer to Figure 4 and Figure 5 The automatic page turning method provided in the embodiment of the present application is based on the automatic page turning device 100 described above, and the automatic page turning method includes the following steps:

[0067] Step S300: When the driving assembly 50 drives the page suction swing lever assembly 30 to move, the driving assembly 50 drives the two page turning levers 40 to rotate in opposite directions on both sides of the sucked paper to turn the sucked paper.

[0073] Further references Figure 5 In step S300, the driving assembly 50 is used to drive the two page turning rods 40 to rotate in opposite directions on both sides of the sucked paper to turn the sucked paper. Specifically, the synchronous wheel 53 is used to drive the two page turning rods 40 to rotate one circle and return to the original position; wherein the page turning rod 40 returns to the original position, that is, the page turning rod 40 returns to the starting position of the page turning rod 40 described in the first embodiment.

[0076] In step S500 , when the driving wheel 52 is driven by the motor 51 to rotate in the second direction, the one-way bearing in the synchronous wheel 53 is used to limit the rotation of the two page turning rods 40 .

[0077] It is meant to be explained that, in one embodiment of the application, the first direction is a clockwise direction and the second direction is a counterclockwise direction.

[0078] The above description is only a preferred embodiment of the present application and is not intended to limit the present application.
