Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] The gear transmission page turning mechanism and automatic shooting machine of the present application are now described in detail with reference to the accompanying drawings.

[0036] Refer to Figure 1 The gear-driven page-turning mechanism 100 provided in the embodiment of the present application includes a base 10, a pre-pressing structure 20, two sliding components 30, a friction page-turning component 40 arranged on each sliding component 30, two page-turning components 50 and a rotation driving component 60.

[0037] Specifically, the base 10 is used to place documents to be turned over. The pre-pressing structure 20 can be rotatably arranged on the side of the base 10 for placing documents and is used to contact and press down the paper to be turned over. Two sliding components 30 can be reciprocatingly slidably arranged on opposite sides of the base 10, wherein each sliding component 30 is provided with a friction page-lifting component 40 that slides with the sliding component 30, and the pre-pressing structure 20 can be movably arranged on one of the sliding components 30, and the sliding sliding component 30 is used to drive the friction page-lifting component 40 to slide to frictionally push up the paper to be turned over and drive the pre-pressing structure 20 to rotate to move away from and release the pressed paper. Two page-turning components 50 are used in conjunction with the two sliding components 30 respectively. The rotation drive component 60 connects the two page-turning components 50, and is used to drive the page-turning component 50 to rotate so as to drive the sliding component 30 to slide in a gearing manner and drive the page-turning component 50 to turn the paper pushed up by the friction page-lifting component 40.

[0038] Combined with reference Figure 1 , Figure 2 and Figure 3 Two page turning assemblies 50 are arranged oppositely on the side of the base 10 for placing certificates, and each page turning assembly 50 includes a driven gear 51 and a page turning swing rod 52 that rotates synchronously and coaxially with the driven gear 51. The page turning swing rod 52 is located between the driven gear 51 and the base 10, and the rotation driving assembly is connected to the driven gear 51 and is used to drive the driven gear 51 to rotate. Therefore, when the rotation driving assembly drives the driven gears 51 of the two page turning assemblies 50 to rotate, the page turning swing rod 52 is also driven to rotate.

[0039] Further, the rotation drive assembly 60 includes a driving gear 61, a driving device for driving the driving gear 61 to rotate, a tail gear 62, an even number of intermediate transmission gears 63 connected to the driving gear 61 and the tail gear 62, a first connecting shaft 64, and a second connecting shaft 65. The driving gear 61 and one of the page turning assemblies 50 are respectively arranged at both ends of the first connecting shaft 64, and the tail gear 62 and another page turning assembly 50 are respectively arranged at both ends of the second connecting shaft 65; specifically, one end of the first connecting shaft 64 is provided with the driving gear 61, and the other end is provided with a driven gear 51 and a page turning swing rod 52 that rotate coaxially with one of the page turning assemblies 50, and one end of the second connecting shaft 65 is provided with the tail gear 62, and the other end is provided with a driven gear 51 and a page turning swing rod 52 that rotate coaxially with another page turning assembly 50.

[0040] In one embodiment, there are two intermediate transmission gears 63, and the driving device is a motor. When the motor drives the driving gear 61 to rotate in the first direction, the driven gear 51 and the page turning swing rod 52 of one of the page turning assemblies 50 are driven to rotate in the first direction through the first connecting shaft 64, and at the same time, one of the intermediate transmission wheels is driven to rotate in the second direction opposite to the first direction through the gearing method, and the other intermediate transmission wheel is driven to rotate in the first direction through the gearing method, and then the tail gear 62 is driven to rotate in the second direction through the gearing method, and the tail gear 62 rotating in the second direction drives the driven gear 51 and the page turning swing rod 52 of the other page turning assembly 50 to rotate in the second direction through the second connecting shaft 65; therefore, the transmission drive member can drive the two page turning assemblies 50 to rotate in opposite directions. It can be understood that since the two page turning assemblies 50 realize page turning on both sides, they need to rotate in opposite directions at the same time.

[0041] Combined with reference Figure 2 and Figure 4 Each sliding assembly 30 includes a slide plate 31, a slide rail 32 for the slide plate 31 to slide, a rack 311 disposed on the slide plate 31 for detachably connecting with the driven gear 51, and a first tension spring 33 disposed on the slide plate 31. The slide rail 32 and the rack 311 are disposed on opposite sides of the slide plate 31, and the expansion and contraction direction of the first tension spring 33 is the same as the sliding direction of the slide plate 31 along the slide rail 32; and each driven gear 51 that rotates is used to realize the intermittent tooth connection and separation of a rack 311.

[0042] The driven gear 51 includes two sector gears 511 that are symmetrically and fixedly connected to each other, and the connection between the two sector gears 511 is coaxially rotatably connected to the middle of the page turning swing rod 52. When the page turning swing rod 52 is parallel to the rack 311 on the slide 31, the rack 311 is connected to the end teeth of the arc surface of a sector gear 511 of the driven gear 51.

[0043] It is worth noting that since the two sector gears 511 are back-to-back symmetrical structures, the edge of the driven gear 51 forms a first area with teeth, a second area without teeth, a third area with teeth and a fourth area without teeth, which are distributed in sequence, and the first area and the third area are symmetrically distributed with the second area and the fourth area, respectively.

[0044] like Figure 1 and Figure 2 The friction sheet-lifting assembly includes a shaft 41 which is perpendicular to the sliding direction of the slide plate 31 and can rotate through the slide plate 31, a torsion spring 42 which is sleeved on the shaft 41, and connecting blocks 44 which are respectively arranged at both ends of the shaft 41 and a cam 43 which is used for frictionally contacting the document paper between the two sliding assemblies 30. In addition, the two ends of the torsion spring 42 are respectively arranged on the connecting block 44 and the slide plate 31.

[0045] Combined with reference Figure 2 , Figure 5 and Figure 6 A boss 312 with a raised curved surface is fixedly provided on the side of the slide 31 away from the base 10. The pre-pressing structure 20 is provided adjacent to the slide 31 and includes a swing plate 21 extending along the sliding direction of the slide 31, a fixed shaft 22 rotatably connected to one end of the swing plate 21, and a swing plate 23 provided on the swing plate 21 for pressing down the document paper on the base 10. The swing plate 21 is provided with a contact block 211 located on the side of the slide 31 provided with the boss 312, and the contact block 211 is provided with an arc-shaped contact surface protruding toward the slide 31. In the process of the driven wheel driving the slide 31 to slide, the curved surface of the boss 312 is in contact with the arc-shaped contact surface of the contact block 211.

[0046] When the slide plate 31 slides, the boss 312 moves until the boss 312 and the contact block 211 collide, so that the boss 312 lifts the swing plate 21 to rotate around the fixed shaft 22, and then the swing plate 23 is lifted up and away from the release paper. During the contact between the curved surface of the boss 312 and the arc-shaped contact surface of the contact block 211, the swing plate 21 is in a state of being lifted by the boss 312. When the slide plate 31 drives the protrusion to continue to move so that the boss 312 is separated from the contact block 211, the swing plate 21 rotates in the opposite direction around the fixed shaft 22 and moves toward the base 10, so that the swing plate 21 returns to the state of pressing down the paper. The boss 312 and the contact block 211 are both set in the form of curved surfaces, which can realize the smooth movement of the swing plate 21.

[0047] Furthermore, the pre-pressing structure 20 further includes a second tension spring 24 disposed on the side of the swing plate 21 facing away from the base 10. Both the boss 312 and the contact block 211 are provided. Through the action of the second tension spring 24, when the boss 312 is separated from the contact block, the swing plate 21 can smoothly fall back to the base 10 to continue pressing down the paper.

[0048] It is worth noting that when the page of the certificate is turned by the gear-driven page turning mechanism 100, the certificate is placed on the base 10 in an open manner. At this time, the certificate is located between the two sliding components 30. When the certificate is placed, the fixed shaft 22 rotates due to the push of the swing plate 23 by the certificate. After the certificate is placed, the swing plate 23 presses down the side of the certificate to be turned, and the cam 43 of the page turning component 50 contacts the outer corner of the paper to be turned. When the components of the gear-driven page turning mechanism are in the starting position, the page turning swing rod 52 is arranged in parallel with the rack 311 on the slide 31. The two page turning swing rods 52 are arranged in parallel on both sides of the certificate of the base 10 and are arranged in parallel with the edge of the certificate. In a set of corresponding page turning components 50 and sliding components 30, the page turning swing rod 52 is arranged in parallel with the rack 311 on the slide 31. As mentioned above, at this time, the rack 311 is connected to the end teeth of the arc surface of a sector gear 511 of the driven gear 51.

[0049] As the rotating driving assembly 60 drives the driven gear 51 to rotate from the starting position, it first passes through the first forward sliding stage: the page turning rocker 52 rotates with the driven wheel, the rack 311 and the fan-shaped gear 511 corresponding to the first area are meshed to drive the slide plate 31 to slide along the slide rail 32. During the sliding process, the first tension spring 33 is stretched, and as the slide plate 31 drives the cam 43 to slide, the cam 43 rubs the paper from the corner of the paper to make the middle part of the paper to be turned arched. During this sliding process, the boss 312 will lift the swing plate 21 to make the swing plate 23 release the arched paper. The rotation drive assembly 60 drives the driven gear 51 to continue rotating and enter the second reverse sliding stage: the driven gear 51 continues to rotate so that the toothless second area faces the rack 311, and the rack 311 and the driven gear 51 are no longer meshed. At this time, the second tension spring 24 drives the slide to slide back to the starting position along the slide rail 32 in the reverse direction. During this reverse sliding process, the driven wheel and the page turning rocker 52 continue to rotate in the original direction. The rotation process of the page turning rocker 52 will turn into the arched area of ​​the paper, so that the rotating rocker will turn the arched paper during the first forward sliding process to the other side. When the slide plate 31 slides reversely to the starting position, the page turning rocker 52 returns to a parallel setting with the rack 311, and the rack 311 and the end of the sector gear 511 corresponding to the third area are meshed.

[0050] It can be understood that when the driven gear 51 and the page turning rocker 52 rotate 180 degrees, the transmission page turning mechanism turns the page 100. If in the previous page turning, the sliding assembly 30 slides back and forth once, due to the action of the torsion spring, the angle of the cam is pre-set. When the slide drives the cam of the friction page turning assembly to move from one side of the paper to be turned to the other side of the paper to be turned, the cam friction drives the paper to be turned to arch up. When the slide drives the cam to move in the opposite direction, the cam moves along the direction of the paper flattening, and the page will not be arched at this time. In this page turning process, the rack has gone through the process of connecting with the sector gear teeth in the first area and separating from the teeth in the second area. Then in the next page turning, the movement form of the sliding assembly is the same as the previous one, except that the rack has gone through the process of connecting with the sector gear teeth in the third area and separating from the teeth in the fourth area, and the page turning is cyclically repeated.

[0051] Please refer to Figure 7 and Figure 8 The automatic camera 200 provided in the embodiment of the present application includes the above-mentioned gear transmission page turning mechanism 100, an upper cover 201 and a camera. A groove 11 for placing a certificate is provided on one side of the base 10. The upper cover 201 covers the base 10 and forms a certificate hole 202 for placing the certificate with the groove 11. The certificate can be placed through the certificate hole 202. The camera is located on the side of the upper cover 201 facing the base 10, and is used to sequentially photograph the contents of the certificate paper in the groove 11. The photographed paper is turned to the other side through the gear transmission page turning mechanism 100.

[0052] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
