[0039] The sliding transmission page turning mechanism and the page turning driving method of the present application are now described in detail with reference to the accompanying drawings.

[0040] Embodiment 1:

[0041] Please refer to Figure 1 and Figure 2 The sliding transmission page turning mechanism 100 provided in the embodiment of the present application is used to realize the automatic page turning function of the certificate, and the certificate may include but is not limited to a passport. The sliding transmission page turning mechanism 100 includes a base 10, a first sliding component 20, a second sliding component 30, a friction page starting component 40 and a page turning component 50.

[0042] Specifically, the base 10 is used to place the certificate to be turned over, and the certificate is opened and placed on the base 10. The first sliding component 20 is located on the side of the base 10 for placing the certificate and can slide up and down relative to the base 10. The second sliding component 30 is slidably arranged on the first sliding component 20. The friction page-opening component 40 and the second sliding component 30 are located above the certificate placed on the base 10, and the first sliding component 20 is located on the side of the certificate placed on the base 10. The page-turning component 50 includes a swing rod with one end rotatably arranged on the first sliding component 20 and a page-turning rod arranged at the other end of the swing rod and can slide back and forth. Among them, the up and down sliding direction is perpendicular to the front and back sliding direction.

[0043] It is worth noting that if Figure 2As shown, before the page is turned, each component of the sliding transmission page turning mechanism 100 is located at the starting position, which is specifically: the second sliding component 30 is located below the document on the front base 10 of the first sliding component 20, the friction page starting component 40 also follows the second sliding component 30 below the document on the front base 10 and the friction page starting component 40 document is located on the side of the paper to be turned, and the page turning rod is also located on the side of the paper to be turned. The up and down sliding involved in this application is all based on the base 10 as a reference, the upward sliding is the sliding in the direction away from the base 10, and the downward sliding is the sliding in the direction close to the base 10. The forward and backward sliding can be the indicated page turning process, for example, the friction page starting component 40 slides backward to realize the page turning process from the side to be turned to the side after turning the page, and the forward sliding is the opposite; the forward and backward sliding directions of other components of the sliding transmission page turning mechanism 100 are also the same.

[0044] In the sliding transmission page turning assembly 50, the friction page starting assembly 40 is used to slide down relative to the base 10 to press and contact the paper, and the paper to be turned is arched by sliding friction during the backward sliding process of the friction page starting assembly 40, and then the second sliding assembly 30 is used to slide backward along the first sliding assembly 20 to drive the friction page starting assembly 40 thereon to move from the side to be turned toward the side after the page is turned, thereby carrying the arched paper to the side after the page is turned, and as the first sliding assembly 20 slides upward in a direction away from the base 10, the second sliding assembly 30 and the friction page starting assembly 40 are also driven to slide upward, and during the movement of the second sliding assembly 30, the swing rod is driven to swing, thereby driving the page turning rod to slide backward to flatten the paper that has been turned.

[0045] like Figure 1 As shown, the sliding transmission page turning assembly 50 also includes two support plates 60 arranged on opposite sides of the base 10, each support plate 60 is provided with a first sliding assembly 20 that slides up and down along the support plate 60, and the two ends of the second sliding assembly 30 are respectively slidably connected to the first sliding assemblies 20 on the two support plates 60, and each first sliding assembly 20 is connected to a page turning assembly 50.

[0046] It can be understood that the first sliding component 20 is firmly mounted above the base 10 through two support plates 60 and two first sliding components 20, so that the friction lifting component 40 movably arranged on the second sliding component 30 is firmly mounted above the base 10, thereby achieving stability during the movement of each component.

[0047] Combined with reference Figure 1 and Figure 3The second sliding assembly 30 includes a support frame 31 slidably disposed on the first sliding assembly 20 and a first slide groove 311 is provided on the support frame 31. In addition, the friction page assembly 40 includes a connecting plate 41 located between the support frame 31 and the base 10, a plurality of sliding rods 42 disposed on the connecting plate 41 and slidably connected to the support frame 31 up and down, a first contact member 43 slidably disposed on the side of the connecting plate 41 away from the support frame 31 and used for frictionally contacting the paper, and a connecting piece 44 disposed on the first contact member 43 and slidable along the first slide groove 311.

[0048] It is worth noting that, when the document is opened, the document on the base 10 can be divided into a side to be turned and a side after turning the page. The friction page-starting component 40 is located at the starting position before turning the page, that is, the friction page-starting component 40 is located at the side to be turned relative to the side after turning the page. At this time, the driving connecting plate 41 slides downward on the bracket through a plurality of sliding rods 42, so that the first contact member 43 and the second contact member on the connecting plate 41 press down to contact the paper, and then drive the connecting plate 44 to slide backward along the first sliding groove 311, thereby driving the first contact member 43 to slide backward to drive the paper to be turned to arch toward the base 10 in a sliding friction manner.

[0049] In addition, the connecting plate 41 can slide up and down to provide space for up and down movement, so as to adapt to different thicknesses of paper to be turned, and as the thickness of the paper to be turned changes continuously, the connecting plate 41 can slide up and down to drive the first contact member 43 and the second contact member thereon to contact the paper.

[0050] Furthermore, the friction page-opening assembly 40 further includes a second contact member 45 fixedly disposed on the side of the connecting plate 41 away from the bracket frame 31 and used for frictionally contacting the paper, and the first contact member 43 and the second contact member 45 are sequentially distributed front to back along the backward sliding direction of the friction page-opening assembly 40. After the first contact member 43 and the second contact member 45 contact the paper to be turned over, the first contact member 43 is driven to slide backward when turning the page. Since the first contact member 43 and the second contact member 45 are distributed front to back, the first contact member 43 moves toward the second contact member 45 during the sliding process. In this way, when the first contact member 43 slides backward, it is equivalent to frictionally clamping and arching the paper to be turned over through the contact points of the first contact member 43 and the second contact member 45 distributed front to back.

[0051] In a specific embodiment, the first contact member 43 and the second contact member 45 both include a sheet metal member connected to the connecting plate 41 and a rubber member disposed on the sheet metal member for frictionally contacting the paper. The rubber member can increase the contact friction with the paper so that the first contact member 43 sliding backward drives the arched paper to be turned.

[0052] Combined with reference Figure 1 and Figure 4Each support plate 60 is provided with a vertical slide rail 61 for the first sliding assembly 20 to slide up and down, and each support plate 60 is provided with a second slide groove 62 for the page turning rod to slide on the side end close to the base 10. In the page turning assembly 50, one end of the page turning rod is provided on the swing rod and the other end passes through the second slide groove 62 and extends to the top of the base 10.

[0053] Furthermore, each first sliding assembly 20 includes a slider 21 sliding along a vertical slide rail 61, a transverse plate 22 fixedly connected to the slider 21, and a transverse slide rail 23 provided on the transverse plate 22 for the second sliding assembly 30 to slide, and the vertical slide rail 61 and the transverse slide rail 23 are perpendicular to each other. Specifically, one end of the swing rod is rotatably provided on the transverse plate 22, and the connecting plate 41 of the second sliding assembly 30 slides along the transverse slide rail 23 to drive the friction start assembly 40 to slide forward and backward as a whole, and the second sliding assembly 30 also includes two sliding seats provided on opposite sides of the bracket frame 31, and the sliding seats slide along the transverse slide rail 23.

[0054] It is worth noting that, as mentioned above, after the friction page-lifting assembly 40 arches the paper to be turned by sliding friction, Figure 4 As shown, the driving support frame 31 slides backward along the transverse slide rail 23 to drive the friction page assembly 40 to move backward to the side behind the page turning, thereby carrying the arched paper to the side behind the page turning. At this point, the driving connecting plate 41 slides upward on the support through a plurality of sliding rods 42 to allow the first contact member 43 and the second contact member 45 to release the paper away from contact. Then, as shown in FIG. Figure 5 As shown, the slider 21 of the first sliding assembly 20 slides upward from the bottom near the base 10 along the vertical slide rail 61, thereby driving the transverse plate 22 to move upward and driving the second sliding assembly 30 to slide upward as a whole. The upward movement of the transverse plate 22 will drive one end of the swing rod to rotate with the transverse plate 22 as the fulcrum, which is the same as driving the other end of the swing rod to swing from front to back, and then drive the page turning rod set on the other end of the swing rod to slide from front to back along the second slide groove 62. When the page turning rod slides horizontally from one side of the paper to be turned to the other side, the paper that has been turned to the other side is flattened during the sliding process of the page turning rod. Because before the movement of the page turning rod, the paper to be turned is arched and carried to the other side by the friction of the page lifting assembly 40, the subsequent sliding page turning rod plays a further flattening effect to prevent the paper after the page is turned from being not completely flattened to the side after the page is turned and hindering the subsequent page turning process.

[0055] It can be understood that after the pages are turned and laid flat, the various components of the sliding transmission page turning mechanism 100 move in the opposite direction back to the initial position to turn the next page, and this reciprocating process is continued to turn the pages automatically.

[0056] like Figure 1As shown, the sliding transmission page turning mechanism 100 also includes a pre-pressing member, the two ends of which are rotatably arranged on the two support plates 60 and are used to contact the paper to be turned of the certificate on the pre-pressing base 10. In addition, a plurality of positioning rods are arranged on the base 10, and the certificate arranged on the base 10 is clamped by the plurality of positioning rods.

[0057] In one application embodiment, the aforementioned forward and backward sliding and up and down sliding can be realized by a motor and a synchronous belt drive, and the movement of the slider 21 of the first sliding component 20, the movement of the sliding seat of the second sliding component 30, and the movement of the connecting plate 41 and the connecting piece 44 of the friction page-turning component 40 can be realized by a motor and a synchronous belt drive. Specifically, taking the movement of the slider 21 as an example, the slide rail transmission page turning mechanism can also include a driving component, which includes a synchronous belt, a motor, and an upper and lower distributed driving wheel and a driven wheel that are all connected to the synchronous belt drive, and the motor drives the driving wheel and the slider 21 is fixedly set on the synchronous belt. It can be understood that when the motor drives the driving wheel to rotate, it drives the driven wheel to rotate, thereby realizing the turnover of the synchronous belt, thereby driving the slider 21 to slide along the vertical slide rail 61.

[0058] Embodiment 2:

[0059] Please refer to Figure 6 The present application also provides a page turning driving method based on the above-mentioned slide rail transmission page turning mechanism, the method comprising the following steps:

[0060] Step S100: driving the friction page-turning assembly located above the base on which the certificate is placed to slide downward toward the base to press and contact the paper to be turned over on the certificate.

[0061] Step S200: driving the friction page-lifting assembly to move backward from the side where the page is to be turned to the other side after the page is turned so as to frictionally lift the paper to be turned.

[0062] Step S300: driving the second slide rail assembly on which the friction page-lifting assembly is arranged to move backward to drive the arched paper to move to the other side after the page is turned.

[0063] Step S400: driving the friction page lifting assembly to slide upwards away from the base to release the contacted paper.

[0064] Step S500: driving the first slide rail assembly on which the second slide rail assembly is arranged to slide upwards away from the base.

[0065] Step S600: The first slide rail assembly moves upward to drive the second slide rail assembly and the friction start assembly to move upward as a whole, and drives a swing rod with one end disposed on the first slide rail assembly to cause the other end of the swing rod to swing from front to back with the first slide rail assembly as a fulcrum.

[0066] Step S700: Using the moving swing rod to drive the page turning rod on the other end of the swing rod to slide backward from the side to be turned to the other side after the page is turned, so as to flatten the paper after the page is turned.

[0067] It is worth noting that the up and down sliding and forward and backward sliding motion mechanisms of the friction page-turning assembly in the above-mentioned steps S100, S200 and S400, and the up and down sliding motion mechanisms of the second slide rail assembly in steps S300 and S500 are consistent with the motion mechanisms of the corresponding components of the sliding transmission page-turning mechanism in Example 1.

[0068] 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.
