[0028] In the prior art, multifunctional scanners typically feature a scanning platform and a main unit. The scanning platform is often a separate structure, primarily used to place documents or paper to be scanned. In some scenarios, the scanned document or paper is wrinkled or bent, making scanning difficult and requiring manual assistance such as flattening. However, the prior art lacks a mechanism for flattening the document.

[0029] Regarding the problems in related technologies, such as Figures 1-4As shown, the utility model provides a multifunctional high-speed scanner, including a scanning platform 20, a pressure roller assembly 30 and a driving mechanism 40; the scanning platform 20 is used to place the scanned document, and baffles 21 are provided on both sides of the scanning platform 20; the pressure roller assembly 30 is arranged on the scanning platform 20, and the pressure roller assembly 30 includes a first pressure roller 31 and a second pressure roller 32 arranged at intervals, and the first pressure roller 31 and the second pressure roller 32 are both slidably arranged between the baffles 21 on both sides; the driving mechanism 40 is provided on the baffle 21 on at least one side, and the first pressure roller 31 and the second pressure roller 32 are both transmission-connected to the driving mechanism 40, and the driving mechanism 40 is used to drive the first pressure roller 31 and the second pressure roller 32 to move closer to or away from each other to level the scanned document. When scanning wrinkled or curled manuscripts, they need to be flattened and spread flat on the scanning platform 20. In this embodiment, the first pressing roller 31 and the second pressing roller 32 are driven by the driving mechanism 40 to move. During the movement of the first pressing roller 31 and the second pressing roller 32, the wrinkled and curled manuscripts can be flattened, and finally the two pressing rollers continuously apply pressure, so that the scanned manuscript is always in a flat state, thereby achieving efficient scanning of the scanned manuscript.

[0030] It is understandable that some manuscripts or papers will inevitably become wrinkled or curled during scanning. In such cases, the manuscript or paper needs to be flattened before scanning. The usual practice is to manually flatten the paper before scanning. This method is time-consuming and labor-intensive, and requires manual maintenance of the flattened paper, resulting in decreased overall work efficiency and reduced scanning quality. In this embodiment, the two pressure rollers are driven by a drive mechanism 40, which drives the two pressure rollers to move relative to or away from each other, thereby flattening the scanned manuscript during movement. Ultimately, the pressure applied by the two pressure rollers maintains the scanned manuscript in a flat state, facilitating rapid scanning and improving scanning quality.

[0031] Furthermore, during operation, the first pressing roller 31 and the second pressing roller 32 press the edge of the scanned document without affecting the area to be scanned, thereby allowing the content in the middle of the paper to be clearly presented and facilitate scanning. Furthermore, by moving the two pressing rollers toward or away from each other, it is possible to apply scanning to different paper sizes. Especially when wrinkles or curls appear on larger pages, such as A1 or A0 paper, manual leveling is labor-intensive and difficult to maintain an overall flat state. At this time, the first pressing roller 31 and the second pressing roller 32 can easily level the paper and keep it flat. Of course, by adjusting the two pressing rollers, it is also possible to achieve operations with curled smaller pages, such as A4 paper.

[0032] In a specific configuration, the drive mechanism 40 can be an electric drive mechanism 40. Specifically, it can realize the movement of the first pressure roller 31 and the second pressure roller 32 by driving the screw rod to rotate by a motor. For example, one end of the first pressure roller 31 is threadedly connected to the screw rod, which is driven by the motor to rotate the screw rod and thereby drive the first pressure roller 31 to move along the extension direction of the side plate. Similarly, the second pressure roller 32 can also be connected by the above-mentioned electric drive method. This method can realize the first pressure roller 31 and the second pressure roller 32 to move toward or away from each other, thereby realizing the flattening operation of the paper. Of course, in some other embodiments, the drive mechanism 40 can also be manually operated. In order to provide a simple implementation method such as Figure 1 、 Figure 2 As shown, the first pressing roller 31 and the second pressing roller 32 are driven to move by manual operation. This method is easy to implement and has a low production cost.

[0033] According to an embodiment provided by the present utility model, Figure 1 、 Figure 2 As shown, the baffle 21 has a chute 211 along its extension direction. Notches are provided on both sides and the top of the chute 211. The first and second pressure rollers 31 and 32 slide in engagement with the notches on one side. The two pressure rollers need to move relative to the side plates. In this embodiment, the notches enable the first and second pressure rollers 31 and 32 to slide in engagement with the chute 211, achieving smooth sliding of the two pressure rollers.

[0034] During the specific setting, slots are provided on the opposite side walls of the two side baffles 21, which are parallel to the slide groove 211 and connected to the slide groove 211; one end of the first pressure roller 31 and the second pressure roller 32 are connected through a driving mechanism 40, and the driving mechanism 40 can drive the first pressure roller 31 and the second pressure roller 32 to slide in the slot.

[0035] According to one embodiment of the present invention, the drive mechanism 40 includes a drive component 41, a connecting rod assembly 42, and two sliding support seats 43. The two sliding support seats 43 are spaced apart in the slide groove 211. The first pressure roller 31 is connected to one of the sliding support seats 43, and the second pressure roller 32 is connected to the remaining sliding support seat 43. The connecting rod assembly 42 includes an articulated seat 423, a first connecting arm 421, and a second connecting arm 422. One end of the first connecting arm 421 and one end of the second connecting arm 422 are both hinged to the articulated seat 423, and the other end of the first connecting arm 421 and the other end of the second connecting arm 422 are hinged to the sliding support seat 43 on one side thereof. The drive component 41 is in transmission connection with the articulated seat 423 to drive the articulated seat 423 to move vertically, thereby driving the two sliding support seats 43 toward or away from each other. When flattening and unfolding scanned manuscripts or papers, it is necessary to maintain stability to prevent damage to the papers or manuscripts. In this embodiment, through the connection between the first connecting arm 421 and the second connecting arm 422, the vertical movement of the hinge seat 423 can be converted into the horizontal movement of the two sliding support seats 43, thereby driving the movement of the two pressure rollers to achieve stable flattening of the paper.

[0036] In the specific configuration, the first connecting arm 421 and the second connecting arm 422 share a hinged support seat, so that the two connecting arms form a "V"-shaped structure. That is, there is a certain distance between the other end of the first connecting arm 421 and the other end of the second connecting arm 422, so that the other end of the first connecting arm 421 is close to one of the sliding support seats 43, and similarly, the other end of the second connecting arm 422 is close to the other sliding support seat 43, and each is hinged to the sliding support seat 43 on the side close to it. During operation, the hinged seat 423 moves up and down under the drive of the driving component 41. During the up and down movement, the angle between the two connecting arms will change accordingly, thereby driving the two sliding support seats 43 to move along the sliding groove. The two sliding support seats 43 are correspondingly connected to the two pressure rollers, thereby driving the two pressure rollers to move closer or farther away.

[0037] In a specific configuration, one end of each sliding support seat 43 is connected to a connecting plate 434, which extends outward from one side of the baffle 21. An elastic connector 44 is provided between the two connecting plates 434. The movement between the two pressure rollers requires a certain degree of stability. In this embodiment, the elastic connector 44 is connected between the connecting plates 434 to improve the stability of the movement between the two pressure rollers.

[0038] In a further example, the elastic connecting member 44 is a spring, and both ends of the spring are respectively connected to the two connecting plates 434, so that a pre-tightening force can be applied during the movement, thereby improving the movement stability of the first pressure roller 31 and the second pressure roller 32.

[0039] In specific applications, slots are provided on the side walls of the side panels on both sides that are opposite to each other, and the connecting plate 434 extends from the slot to connect with the sliding support seat 43. Part of the physical structure of the connecting plate 434 is exposed on the outer wall of the side wall, and the spring is connected between the two connecting plates 434, so as to provide a stable force during movement and improve the stability of movement.

[0040] According to some embodiments provided by the present invention, a roller shaft 433 is provided on the sliding support seat 43, and the first pressure roller 31 and the second pressure roller 32 are both rotatably connected to the roller shaft 433. A hinge portion 431 is provided at the top of the sliding support seat 43, and the first connecting arm 421 and the second connecting arm 422 are both hinged to the hinge portion 431. A roller 432 is provided at the bottom of the support seat, and the roller 432 slides in conjunction with the slide groove 211. When driving the sliding support seat 43 to move, it is necessary to maintain smooth movement. In this embodiment, by providing the roller 432 at the bottom of the sliding support seat 43, the sliding support seat 43 can be rolled, thereby reducing friction during movement and improving the stability and smoothness of the movement of the sliding support seat 43.

[0041] Specifically, the ends of the first pressing roller 31 and the second pressing roller 32 are provided with shaft holes, which cooperate with the roller shaft 433 so that the pressing rollers can rotate around the roller shaft 433. Of course, during the specific connection, they can be connected through bearings to ensure the smoothness of the rotation of the pressing rollers.

[0042] It can be understood that the first pressing roller 31 and the second pressing roller 32 have a certain weight. When working, their gravity is completely applied to the manuscript or paper. During the movement, the first pressing roller 31 and the second pressing roller 32 can rotate and try to flatten the wrinkles and curls to maintain the overall flatness.

[0043] In some embodiments, a lifting device can be used to drive the cross-connection seat up and down, thereby driving the first connecting arm 421 and the second connecting arm 422. For example, the drive can be achieved by a linear drive component 41, which is mounted on the side panel and has its output connected to the articulated seat 423, thereby driving the articulated seat 423. The linear drive component 41 can be a linear motor, a hydraulic cylinder, a pneumatic cylinder, or the like.

[0044] like Figure 1As shown, a driving mechanism 40 can be provided on both sides of the side panels to drive the side panels on both sides at the same time to realize the movement of the two pressure rollers. This method can make the force on the two pressure rollers more uniform and their movement more stable. When two driving structures are provided at the same time, a synchronization mechanism needs to be provided to ensure that the driving mechanisms 40 on both sides move synchronously. For example, when linear motors are provided on both sides at the same time, the two linear motors are controlled by a synchronous control system to realize the simultaneous start of the two motors and simultaneously drive the articulated seat 423 to move up and down. Among them, the synchronous control system part is an existing conventional technology and will not be described in detail. Of course, the driving mechanism 40 can also be provided on one side of the side panel. In this case, a follower structure can be provided on the other side to only play a supporting role to ensure the stable operation of the two pressure rollers.

[0045] When the drive mechanism 40 is only provided on one side panel, a linear motor or cylinder device may be connected to the side panel on one side, and a lifting rod may be provided on the side panel on the other side, that is, the lifting rod is connected to the hinge seat 423 on the other side. When the linear motor or cylinder device on one side is driven, the lifting rod on the other side follows the movement to provide support for the hinge seat 423. Of course, in addition to the above-mentioned automatic drive method, this embodiment provides specific instructions for manual operation, as shown in the attached figure. Figure 1 and attached Figure 2 shown.

[0046] In a specific embodiment, the drive component 41 includes a drive screw, one end of which is rotatably mounted on the baffle 21. The hinge seat 423 is threadedly connected to the drive screw, so that the hinge seat 423 can be moved vertically by rotating the drive screw. The drive screw facilitates the transmission settings of manual and automatic devices, thereby driving the movement of the two pressure rollers.

[0047] Specifically, a threaded sleeve 424 is connected to the hinge seat 423, and the threaded sleeve 424 is sleeved on the driving screw. When the driving screw rotates, it can drive the threaded sleeve 424 to move along the axis of the screw, thereby realizing the movement of the two pressure rollers.

[0048] When performing manual settings, such as Figure 1 and Figure 2 As shown, a handle is directly provided at the top of the driving screw, and the driving screw can be rotated by turning the handle. It should be noted that the figure only shows the manual setting state, and omits the automatic driving state.

[0049] When the drive is automatic, a drive motor can be provided at the bottom of the drive screw, and the drive motor drives the drive screw to rotate, thereby realizing the movement of the sliding support seat 43. Of course, those skilled in the art can choose the number of drive mechanisms 40 when they know this embodiment, and can refer to Figure 1Although two drive mechanisms 40 are shown, only one drive mechanism 40 may be provided.

[0050] According to an embodiment provided by the present invention, the multifunctional high-speed scanner also includes a host platform 10 and a high-speed scanner support arm 50. The host platform 10 is arranged on one side of the scanning platform 20, and the high-speed scanner support arm 50 is arranged on the host platform 10; wherein, the high-speed scanner support arm 50 includes a lifting adjustment mechanism 70, and the lifting adjustment mechanism 70 is used to adjust the height of the high-speed scanner support arm 50.

[0051] It is understood that conventional high-definition cameras include a camera for scanning and taking pictures and a high-definition camera support arm 50. The high-definition camera support arm 50 is connected to the host platform 10 and performs other functions through the host platform 10. In this embodiment, the height of the high-definition camera support arm 50 can be adjusted by setting the lifting adjustment mechanism 70, thereby improving the applicability of the high-definition camera.

[0052] In specific settings, a signature screen 11 and a fingerprint recognition slot are provided on the host platform 10. The signature screen 11 is used for the operator to sign, and the fingerprint recognition slot is used to identify the operator's identity and enter the signature and fingerprint.

[0053] According to the embodiment provided by the present invention, the high-shooting support arm 50 includes a fixed support tube 51 and a lifting support arm 52. The lifting support arm 52 is slidably disposed within the fixed support tube 51. The lifting adjustment mechanism 70 is in transmission connection with the lifting support arm 52 to drive the lifting support arm 52 to move up and down relative to the fixed support tube 51. During the lifting operation, it is necessary to maintain overall stability. In this embodiment, the arrangement of the support arm within the fixed support tube 51 can make the lifting process more stable.

[0054] It can be understood that the support arm is inserted into the fixed support tube 51, and the fixed support tube 51 is fixed on the main platform. The support arm can move relative to the fixed support tube 51, thereby realizing the height change of the high-shooting support arm 50, which is suitable for different height requirements.

[0055] It can be understood that the lifting and adjusting mechanism 70 can be an automatic lifting device, for example, it can be realized by setting a linear motor, which is arranged on the host platform 10, and the driving end of the linear motor is connected to the support arm, thereby driving the support arm to move up and down.

[0056] According to the specific implementation mode provided by the present utility model, as Figure 3 、 Figure 4As shown, the lifting adjustment mechanism 70 includes a worm gear 72, a worm shaft 71, and a lifting screw 73. The worm gear 72 is provided on the lifting screw 73. One end of the lifting screw 73 is rotatably connected to the host platform 10, and the other end of the lifting screw 73 is threadedly connected to the lifting support arm 52. The worm shaft 71 and the worm gear 72 are engaged and driven to drive the lifting screw 73 to rotate, thereby driving the support arm to move up and down. When adjusting the height of the high-rise support arm 50, the up and down movement needs to be relatively stable. In this embodiment, the worm gear and the worm shaft are used to drive the screw 73 to rotate, thereby achieving the up and down movement of the lifting support arm 52, thereby stably adjusting the height of the high-rise support arm 50.

[0057] Specifically, the worm portion 71 is connected to a knob 74 , which is convenient for manual gripping and rotation, thereby driving the worm gear portion 72 to rotate, and further driving the screw 73 to rotate, thereby achieving height adjustment of the high-shooing support arm 50 .

[0058] According to the embodiment provided by the present invention, a cantilever 53 is provided on the top of the lifting support arm 52, the cantilever 53 is arranged horizontally, and a portion of the cantilever 53 is located directly above the scanning platform 20. By arranging the cantilever 53 above the scanning platform 20, the scanning operation is facilitated.

[0059] Specifically, a fill light 531 and a scanning camera 532 are provided on the bottom wall of the cantilever 53 above the scanning platform 20. The fill light 531 enables clearer scanning. Furthermore, a camera 60 is movably connected to the top of the cantilever 53 at one end of the host platform 10, which can capture images of people.

[0060] It can be seen from the above embodiments that the technical solution of the utility model can be widely used in various business halls to carry out paperless services such as portrait photography, person-ID comparison, document scanning, ID card reading, card opening, customer signature, etc. It can also be widely used in banks, express delivery, medical and other industries.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
