[0035] The page turning device, page turning scanning device and page turning driving method of the present application are now described in detail with reference to the accompanying drawings.

[0036] Please refer to Figure 1 and Figure 2 The page turning device 100 provided in the embodiment of the present application includes a base 10, a roller brush assembly 20, a first suction cup 30, a page turning rod 40 and a clamping rod 50. The base 10 is used to place the certificate to be turned. The roller brush assembly 20 is arranged on the base 10 and is used to turn over the paper on the side of the certificate to be turned. The first suction cup 30 is fixedly connected to the base 10 and is located on the side of the base 10 for placing the certificate. The first suction cup 30 is used to suck the paper turned over by the roller brush assembly 20. The page turning rod 40 can be reciprocatingly slidably arranged on the base 10 to turn over the paper sucked by the first suction cup 30. The clamping rod 50 can be rotatably clamped on the edge of the base 10 and is used to press the paper on the side after turning the page.

[0037] Refer to Figure 3 The page turning device 100 further includes a sliding drive assembly 70 for driving the page turning lever 40 to slide back and forth, and two support plates 60 disposed on opposite sides of the base 10 , and the certificate placed on the base 10 is located between the two support plates 60 .

[0038] Specifically, the sliding drive assembly 70 includes a motor 71 disposed on the side of the base 10 facing away from the document, a rotating shaft 72 disposed on the same side of the base 10 as the motor 71, two driving wheels 73 disposed at both ends of the rotating shaft 72, a plurality of tensioning wheels 74 disposed on each support plate 60, and a synchronous belt 75 for transmission connection between a driving wheel 73 and a plurality of tensioning wheels 74 on a support plate 60. That is, a plurality of tensioning wheels 74 are disposed on each support plate 60, and a plurality of tensioning wheels 74 on each support plate 60 and a driving wheel 73 are transmission-connected by a synchronous belt 75. In addition, a page shifting rod 40 is fixedly disposed on each synchronous belt 75, and a pressing rod 50 is fixedly disposed on the rotating shaft 72. In the process of turning pages, the two page shifting rods 40 located on both sides of the document slide and turn pages simultaneously.

[0039] Furthermore, the clamping rod 50 is a U-shaped rod, which is bent and extended from the side of the base 10 where the motor 71 is provided to the side of the base 10 where the certificate is placed; and the clamping rod 50 is fixedly provided on the rotating shaft 72. After sliding to the side after turning the page, the page lever 40 needs to slide back to the side to be turned to turn the page for the next time, and in the process of the page lever 40 sliding back in the above-mentioned reverse direction, in order to prevent the page lever 40 from driving the paper after turning the page to rebound when retreating, the page lever 40 is driven to rotate so that the U-shaped page lever 40 is at the edge of the base 10 to hold the paper on the side after turning the page.

[0040] It is worth noting that when the sliding drive assembly 70 drives the page-turning lever 40 to slide, the rotating shaft 72 will drive the pressing lever 50 to rotate. Specifically, when turning pages, when the motor 71 drives the rotating shaft 72 to rotate in the first direction, the page-turning lever 40 located at the original position is driven to slide from the side to be turned to the side after the page is turned, and the rotating rotating shaft 72 drives the pressing lever 50 thereon to rotate to a state where the paper on the side after the page is turned is not clamped, that is, when the page-turning lever 40 slides to turn pages, the pressing lever 50 needs to be gradually driven to open to prevent the pressing lever 50 from blocking the turned paper from falling onto the base 10. After turning the page, the motor 71 drives the rotating shaft 72 to rotate in the second direction, driving the page lever 40 to slide from the side after turning the page to the side to be turned to the original position before turning the page, and the rotating rotating shaft 72 drives the clamping rod 50 thereon to rotate to a state of clamping the paper on the side after turning the page, which is equivalent to the reverse driving of the clamping rod 50 when the page lever 40 returns after turning the page, which can effectively prevent the rebound of the paper after the page lever 40 drives the page lever 40 to turn the page when the page lever 40 retreats. In the present application, a sliding drive assembly 70 synchronously realizes the rotation of the clamping rod 50 and the sliding of the page lever 40, while also reducing the use of components, that is, high efficiency and economical.

[0041] In one embodiment of the application, the number of the first suction cup 30 and the page-turning rod 40 is the same, that is, two. A first suction cup 30 is fixedly disposed on each support plate 60, and the two first suction cups 30 are disposed side by side. In order to facilitate page turning, the page-turning rod 40 is closer to the surface of the base 10 than the first suction cup 30, so that the page-turning rod 40 slides on the side to be turned through the arched area formed by the paper turned up by the brush and sucked by the first suction cup 30, and the page-turning rod 40 can more conveniently turn the paper over during the continuous sliding of the page-turning rod 40.

[0042] like Figure 2 and Figure 3 As shown, the roller brush assembly 20 includes two brushes 21 disposed on opposite sides of the base 10 and a rolling drive assembly 22 connecting the two brushes 21. Each of the brushes 21 is disposed on the same side as one of the support plates 60; the rolling drive assembly 22 is used to drive the two brushes 21 to rotate synchronously and oppositely to each other so as to flip up the paper to be turned relative to the base 10 or flip down the paper relative to the base 10. Multiple rows of bristles are arranged at intervals on each brush 21. It can be understood that the paper to be turned is arranged between the two brushes 21. The two brushes 21 rotate in opposite directions on both sides of the paper to be turned at the same time to generate airflow to turn the paper.

[0043] Further, the rolling drive assembly 22 includes a driving device 221, a driving gear 222 driven to rotate by the driving device 221, a first driven gear 223 and a second driven gear 224 connected to the driving gear 222, a first driving shaft 225 with the first driven gear 223 at one end, a second driving shaft 226 with the second driven gear 224 at one end, a first driving gear 227 disposed at the other end of the first driving shaft 225, a second driving gear 228 disposed at the other end of the second driving shaft 226, a third driving gear 229 coaxially rotating with one of the brushes 21 and connected to the first driving gear 227, and another third driving gear 229 coaxially rotating with the other brush 21 and connected to the second driving gear 228. The driving device 221 may be, but is not limited to, a servo motor 71.

[0044] It can be understood that the driving gear 222 is driven to rotate by the driving device 221, and the driving gear 222 drives the first driven gear 223 and the second driven gear 224 meshing therewith to rotate in opposite directions. When the first driven gear 223 and the second driven gear 224 respectively drive the first driving shaft 225 and the second driving shaft 226 to rotate, the first driving gear 227 on the first driving shaft 225 and the second driving gear 228 on the second driving shaft 226 are driven to rotate in the opposite direction. At this time, the first driving gear 227 and the second driving gear 228 respectively synchronously drive the third driving gear 229 and the fourth driving gear to rotate in the opposite direction, so that the two brushes 21 on the opposite sides of the base 10 can rotate in the opposite direction at the same time.

[0045] It is worth mentioning that the certificate to be turned is opened and placed on the base 10. After the certificate is placed, the clamping rod 50 is located on the side behind the certificate to be turned, and the side of the certificate to be turned is located between the two brushes 21. When turning the page, the clamping rod 50 is driven to rotate so that the U-shaped clamping rod 50 is at the edge of the base 10 and is not clamped on the paper on the side behind the page turning, so as to prevent the turned paper from being blocked from being laid flat on the base 10 during the page turning process. After the clamping rod 50 is rotated to a non-clamping state, the rolling drive assembly 22 of the roller brush assembly 20 drives the two roller brushes to rotate in opposite directions at the same time to turn over the paper on the side to be turned. Since the two brushes 21 are constantly rotating, multiple pages of paper will be gradually turned over, and the turned-over paper will also be stacked. However, paging needs to be achieved page by page when turning the page, so the first suction cup 30 above the certificate on the base 10 sucks the surface of the first page of paper turned over by the brush 21. The first page of paper can be understood as the topmost paper turned over by the brush 21. That is, the page of paper on the side to be turned on the base 10 that is farthest from the surface of the base 10. Then, the two brushes 21 are driven to rotate in the opposite direction relative to the turned-up paper, so that the turned-up paper will be turned back to the base 10, and the aforementioned first page of paper will not be turned back to the base 10 due to the action of the first suction cup 30; then, the page-turning rod 40 is driven to slide from the edge of the base 10 from the side to be turned to the side after turning the page, and the page-turning rod 40 turns the paper sucked by the first suction cup 30 to the other side during the sliding process.

[0046] Furthermore, a photoelectric switch is provided on the side of the base 10 away from the side for placing the certificate, and a photoelectric baffle is provided on the above-mentioned page lever 40, which rotates with the page lever 40, and the photoelectric baffle is used to block the light beam emitted by the photoelectric switch. When the light beam of the photoelectric switch is not blocked, the photoelectric switch generates a photoelectric signal, and when the page lever 40 is rotated, the photoelectric baffle on it will be driven to rotate. When the page lever 40 rotates to a certain angle to become a paper state on the side after the page is turned, the photoelectric baffle completely blocks the light beam of the photoelectric switch, and the photoelectric signal of the photoelectric switch is disconnected, that is, when the photoelectric switch generates a photoelectric signal to the time when the photoelectric signal is disconnected, it means that the page lever 40 rotates to a certain angle to become a paper state on the side after the page is turned. Since the sliding of the page lever 40 and the rotation of the clamping rod 50 are performed synchronously, the page lever 40 rotates to a certain angle to become a paper state on the side after the page is turned, and the page lever 40 just slides from the original position to complete the page turning. That is, when the photoelectric switch changes from generating a photoelectric signal to disconnecting the photoelectric signal, the motor 71 is used to rotate in the reverse direction to drive the page-turning lever 40 to return to the side to be turned and at the same time drive the clamping lever 50 to gradually rotate to clamp the paper on the side after turning the page.

[0047] In one application embodiment, the aforementioned certain angle can be about 30 degrees, and can be designed as follows: the rotating shaft 72 rotates 30 degrees clockwise, the clamping rod 50 rotates to complete the non-paper holding state, and the page shifting rod 40 slides from the original position to complete the page turning on one side; the rotating shaft 72 rotates 30 degrees counterclockwise, the clamping rod 50 rotates to complete the paper holding state, and the page shifting rod 40 returns to the original position from the side after the page turning.

[0048] Furthermore, in order to further ensure the smooth page turning transmission process, two photoelectric switches are respectively provided at both ends of the sliding stroke of the page lever 40, and a photoelectric baffle is also provided on the page lever 40. When the photoelectric baffle blocks the photoelectric switch beam, the position of the page lever 40 can be known. In this way, it plays a double protection role with the clamping rod 50.

[0049] Further references Figure 1 The page turning device 100 also includes at least one second suction cup 11 embedded in the base 10, and the first suction cup 30 and the second suction cup 11 are respectively arranged on opposite sides of the document on the base 10. When the roller brush assembly 20 turns over the paper, the first suction cup 30 is used to suck and limit the position of the document on the document.

[0050] When the brush 21 rotates to turn the paper, the force of the brush 21 may prevent the document on the base 10 from shifting. At this time, the second suction cup 11 embedded in the base 10 can be used to limit the document to prevent it from shifting at will. Specifically, at least one through hole is opened on the area of ​​the base 10 for placing the paper on the side to be turned, and a second suction cup 11 is embedded in one through hole, which is equivalent to using the second suction cup 11 to suck and limit the document at the bottom, and using the first suction cup 30 to suck the top first page of paper turned by the brush 21 each time.

[0051] Furthermore, the page turning device 100 also includes a limit rod 13 fixedly arranged on the base 10 for limiting the placement position of the document. The limit rod 13 and the clamping rod 50 are located on the same edge of the base 10. When the clamping rod 50 is in the state of clamping the document on the base 10, the limit rod 13 is located in the U-shaped area of ​​the clamping rod 50.

[0052] It can be understood that the connection between the two sides of the opened certificate placed on the base 10 is the dividing line, the base 10 is used to place the paper to be turned as the side area to be turned, and the base 10 is used to place the paper after turning as the side area after turning. The above-mentioned limit rod 13 and the pressing rod 50 are located in the side area after turning, and the first suction cup 30 and the second suction cup 11 are located in the side area to be turned. The limit rod 13 is used to limit the outer edge of the certificate placed on the base 10 for subsequent turning.

[0053] Combined with reference Figure 2 and Figure 4As shown, the base 10 is provided with two first arched holes 12 arranged side by side. The page turning device 100 further includes two support plates 60, which are respectively fixedly connected to the two sides of the base 10 provided with the brushes 21, and each support plate 60 is provided with a second arched hole 61 mounted on a first arched hole 12, and each first arched hole 12 is connected with a second arched hole 61 to form a receiving area. The first suction cup 30 is provided on the support plate 60, and the certificate on the base 10 is placed between the two receiving areas, and each brush 21 is rotatably provided in a receiving area.

[0054] It is worth noting that one side of the base 10 is used to place the certificate, the rolling drive assembly 22 is arranged on the other side of the base 10, the sliding drive assembly 70 is on both sides of the base 10 and extends along the support plate 60 on the base 10, and the page turning rod 40 and the first suction cup 30 are arranged on the support plate 60, and the brush 21 is arranged in the accommodation area formed by the aforementioned support plate 60 and the base 10. In this way, the page turning device 100 generally forms an upper and lower stacking structure, and the components can be reasonably deployed using the open hole structure, which is conducive to the miniaturization of the page turning device 100 and the reasonable planning of space to reduce the space occupied by components.

[0055] The page turning scanning device provided in the embodiment of the present application includes a scanner arranged on one side of the base 10 for placing the certificate and the aforementioned page turning device 100.

[0056] The scanner is located above the document to be scanned, and its lens faces the paper to be turned. The scanner is used to scan the paper on the turning side of the document; the turning device 100 is used to automatically turn the paper scanned by the scanner.

[0057] In the above implementation, the scanner, the first suction cup 30 and the second suction cup 11 , each motor 71 and each photoelectric switch are connected to the main control chip.

[0058] Please refer to Figure 5 The page turning driving method provided in the embodiment of the present application is based on the above-mentioned page turning device, and the page turning driving method includes the following steps S100 to S600:

[0059] Step S100: using the roller brush assembly on the base to turn over the paper on the side to be turned over of the certificate on the base in a first direction;

[0060] Step S200: using the first suction cup to suck the first page of all the papers turned up by the roller brush assembly to be turned over, and using the roller brush assembly to turn down the remaining papers turned up by the roller brush assembly in a second direction;

[0061] Step S300: turning the page of the paper held by the first suction cup by driving the page turning lever to slide from the side to be turned to the side after turning the page;

[0062] Step S400: simultaneously driving a pressing rod movably disposed on the edge of the base to rotate so that the pressing rod is in a state of not clamping the paper on the back side of the flipped page of the document;

[0063] Step S500: driving the page turning lever to slide from the side after turning the page to the side to turn the page;

[0064] Step S600: driving the pressing rod to rotate simultaneously so that the pressing rod is in a state of clamping the paper on the back side of the page turning;

[0065] In the above steps, the first direction and the second direction are opposite directions to each other.

[0066] In one embodiment of the application, the process of sliding the movable page lever and driving the pressing lever to rotate is as follows:

[0067] Using a motor to drive the shaft to rotate;

[0068] When the rotating shaft drives the driving wheel to rotate, the synchronous belt connecting the driving wheel and the tensioning wheel rotates;

[0069] The page-shifting lever is carried by the rotating synchronous belt to slide and the pressing lever on the rotating shaft is carried by the rotating shaft to rotate.

[0070] In one embodiment of the application, when the pressing rod is driven to rotate, the page turning driving method further includes: using a photoelectric switch on the base to detect the state of the pressing rod and the page turning state of the page turning rod:

[0071] When the photoelectric baffle on the clamping rod blocks the photoelectric switch, it is determined that the clamping rod is in a state of not holding the document on the rear side of the page turning and the page lever has completed the page turning;

[0072] The motor drives the rotating shaft to rotate to drive the page shifting rod to slide from the side behind the page turning to the side to be turned. During the sliding process of the page shifting rod, the rotating shaft drives the clamping rod to rotate to hold the paper on the side behind the page turning.

[0073] In one embodiment of the application, when the roller brush assembly on the base is used to turn over the paper on the to-be-turned side of the certificate on the base in a first direction, the page turning driving method further includes:

[0074] The second suction cup embedded in the base is used to suck the paper from the side where the paper to be turned contacts the base.
