Description

Technical Field

[0001] This utility model relates to the field of document information collection technology, specifically an intelligent document collection terminal for RPA processes. Background Technology

[0002] In the process of implementing RPA (Robotic Process Automation) technology in enterprises, "document collection" is the starting point for many processes (such as financial reimbursement, procurement warehousing, and logistics reconciliation). It is also a bottleneck link in traditional RPA processes that is easily constrained by "unstructured data" and "physical documents". As the core device connecting "physical / electronic documents" and "RPA automated processes", the intelligent document collection terminal integrates OCR (Optical Character Recognition), AI data verification, multimodal input and other capabilities to achieve "automatic recognition, accurate extraction, compliance verification and seamless integration with RPA" of document information, solving the problems of low efficiency, high error and process gaps in traditional manual data entry.

[0003] The physical document input method used in the existing technology scans the information of the document through a built-in or external scanning module (such as a high-speed scanner or a high-definition camera). The document needs to be placed in front of the camera manually so that the camera can record the document information for subsequent information extraction and input.

[0004] However, this type of physical document input method has some problems in actual operation. For example, if the document is wrinkled or shadowed during the shooting process, it will affect the subsequent information collection work. To address this, we propose an intelligent document collection terminal for RPA processes. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an intelligent document collection terminal for RPA processes, which avoids wrinkles or shadows from affecting subsequent document information collection operations, and can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent document collection terminal for RPA processes, including a collection platform, an upper and lower movable plate on the upper side of the collection platform, an industrial camera fixedly connected to the middle of the lower surface of the upper and lower movable plate, and a mechanism for removing light and shadow and wrinkles.

[0007] The light and shadow removal and wrinkle removal mechanism includes fixed hinge supports, rotating hinge supports, rotating plates, transparent acrylic plates, transverse slides, and deflectors. The fixed hinge supports are symmetrically fixed to the lower surface of the upper and lower movable plates. Rotating hinge supports are rotatably connected to the interior of the two fixed hinge supports. Rotating plates are fixedly connected to the lower ends of the two rotating hinge supports. Transparent acrylic plates are evenly distributed and fixedly connected to the opposite inner surfaces of the two rotating plates. Transverse slides are opened on the front side of the left rotating plate and the rear side of the right rotating plate. Deflectors are slidably connected inside the transverse slides. The transparent acrylic plates on the left and right are staggered to avoid wrinkles or shadows affecting subsequent document information collection operations.

[0008] Furthermore, a gantry frame is fixedly connected to the upper side of the acquisition platform, and a controller is fixedly connected to the upper end of the gantry frame. The industrial camera is bidirectionally electrically connected to the controller, and the input end of the controller is electrically connected to an external power source. An external interface is provided on the left side of the gantry frame, and the controller is bidirectionally electrically connected to the external interface to control the normal operation of each electrical component.

[0009] Furthermore, the anti-shading and anti-wrinkle mechanism also includes telescopic rods, levers, and return springs. The telescopic rods are symmetrically fixedly connected to the lower surface of the upper and lower moving plates. Levers are fixedly connected to the telescopic ends of the two telescopic rods respectively. The left side of the front side of the lever is fixedly connected to the rear end of the front lever, and the right side of the rear side of the lever is fixedly connected to the front end of the rear lever. Return springs are fixedly connected to the upper surfaces of the two levers respectively. The upper ends of the two return springs are fixedly connected to the lower surface of an upper and lower moving plate. The two return springs are movably sleeved with the outer arc surface of the telescopic rod located on the same side to provide power for reset.

[0010] Furthermore, pressure plates are fixedly connected to the lower ends of the two levers to achieve the function of pre-pressing the work order.

[0011] Furthermore, it also includes a drive mechanism, which includes a buckle, a linear driver, guide rails, and guide sliders. The buckle is fixedly connected to the upper side wall of the gantry frame. Guide rails are respectively provided in the middle of the left side and the middle of the right side of the buckle frame. Guide sliders are slidably connected inside the two guide rails. The two guide sliders are fixedly connected to the outer side of an upper and lower moving plate. A linear driver is fixedly connected to the upper end of the gantry frame. The output shaft of the linear driver is fixedly connected to the upper end of the upper and lower moving plate. The input end of the linear driver is electrically connected to the output end of the controller to realize the function of adjusting the upper and lower moving plate.

[0012] Furthermore, the acquisition station is equipped with a conveyor belt inside, and the input end of the conveyor belt drive is electrically connected to the output end of the controller to realize the function of moving work orders.

[0013] Furthermore, the lower surface edge of the upper and lower movable plates is provided with uniformly distributed lighting lamps, and the input ends of the lighting lamps are electrically connected to the output end of the controller to realize the function of supplementary lighting.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This intelligent document collection terminal for RPA processes has the following advantages:

[0015] The pressure bar drive structure drives two sets of staggered transparent acrylic plates to smooth the document from the middle to both sides, and finally flatten the document. This prevents wrinkles or shadows from affecting the subsequent document information collection work during the shooting stage. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6This embodiment provides a technical solution: an intelligent document collection terminal for RPA process, including a collection platform 1, an upper and lower movable plate 2 is provided on the upper side of the collection platform 1, an industrial camera 5 is fixedly connected to the middle of the lower surface of the upper and lower movable plate 2, and includes a light and shadow removal and wrinkle removal mechanism 3.

[0025] A gantry frame is fixedly connected to the upper side of the data acquisition station 1. A controller 9 is fixedly connected to the upper end of the gantry frame. The industrial camera 5 is bidirectionally electrically connected to the controller 9. The input end of the controller 9 is electrically connected to an external power supply. An external interface 8 is provided on the left side of the gantry frame (the external interface 8 can be equipped with different data interfaces according to the working conditions, such as USB interface, RS485 interface and video interface). The controller 9 is bidirectionally electrically connected to the external interface 8. When the intelligent document acquisition terminal needs to be used, the interface of the external controller can be inserted into the external interface 8 to realize the external controller controlling the acquisition terminal. Alternatively, the document acquisition terminal can be controlled by adjusting the controller 9 until it moves to the lower side of the industrial camera 5. At this time, the controller 9 is adjusted, the industrial camera 5 operates, and the industrial camera 5 transmits the real-time image captured to the controller 9. At this time, the controller 9 determines that when the document in the image has moved to the bottom, the industrial camera 5 can collect the document information captured at this time.

[0026] The lower surface edge of the vertical moving plate 2 is provided with evenly distributed lighting lamps 6. The input end of each lighting lamp 6 is electrically connected to the output end of the controller 9. The controller 9 is adjusted and turned on to perform supplementary lighting operation.

[0027] The data collection station 1 is equipped with a conveyor belt 10. The input end of the drive motor of the conveyor belt 10 is electrically connected to the output end of the controller 9. (The conveyor belt 10 consists of an electric roller, a frame, idlers, and a conveyor belt. The electric roller has a built-in drive motor, reducer, and coupling. The input end of the drive motor is electrically connected to the output end of the controller 9. The roller housing and the frame support the electric roller, idlers, and other components. The idlers assist in supporting the conveyor belt in the unpowered area, receiving materials and conveying them as the roller rotates. The electric roller acts as the "drive roller." The conveyor belt is wrapped between the electric roller and the "redirecting roller" at the end. When the electric roller housing rotates, the friction between its surface and the inside of the conveyor belt drives the conveyor belt to circulate. The work order placed on the conveyor belt moves with the conveyor belt.) At this time, the staff can place the documents that need to be collected on the conveyor belt 10, and then adjust the conveyor belt 10 to move the documents on the conveyor belt to the center.

[0028] It also includes a drive mechanism 7, which includes a buckle 71, a linear actuator 72, a guide rail 73, and a guide slider 74. The buckle 71 is fixedly connected to the upper side wall of the gantry frame. The middle of the left side and the middle of the right side of the buckle 71 are respectively provided with guide rails 73. The guide sliders 74 are slidably connected inside the two guide rails 73. The two guide sliders 74 are fixedly connected to the outer side of a vertical moving plate 2. The upper end of the gantry frame is fixedly connected to the linear actuator 72. The output shaft of the linear actuator 72 is fixedly connected to the upper end of the vertical moving plate 2. (When the telescopic end of the linear actuator 72 telescopically moves the vertical moving plate 2 up and down, the guide rails 73 and the guide sliders 74 restrict the movement direction of the guide rails 73 and the guide sliders 74, so that the telescopic end of the linear actuator 72 is only subjected to vertical load, while the lateral load on the telescopic end of the linear actuator 72 is small, thus protecting the linear actuator 72.) The input end of the linear actuator 72 is electrically connected to the output end of the controller 9, so that the controller 9 can be adjusted. The telescopic end of the linear actuator 72 extends, thereby pushing the vertical moving plate 2 down a specified length.

[0029] The light and shadow removal and wrinkle removal mechanism 3 includes a fixed hinge support 31, a rotating hinge support 32, a rotating plate 33, a transparent acrylic plate 34, a transverse slide 35, and a lever 38. The fixed hinge supports 31 are symmetrically fixed to the lower surface of the upper and lower movable plates 2. The rotating hinge supports 32 are rotatably connected to the interior of the two fixed hinge supports 31. The lower ends of the two rotating hinge supports 32 are respectively fixedly connected to the rotating plates 33. The inner surfaces of the two rotating plates 33 are respectively fixedly connected to evenly distributed transparent acrylic plates 34 (the lower surface of the transparent acrylic plates 34 needs to be rounded to prevent scratching the documents). The front side of the left rotating plate 33 and the rear side of the right rotating plate 33 are respectively provided with transverse slides. The transverse sliding groove 35 is slidably connected to the push pin 38. The transparent acrylic plate 34 on the left and the transparent acrylic plate 34 on the right are staggered, which drives the rotating plate 33 on the left to rotate counterclockwise at the hinge point of the fixed hinge support 31 on the left and the rotating hinge support 32 on the left. Meanwhile, the rotating plate 33 on the right rotates clockwise at the hinge point of the fixed hinge support 31 on the right and the rotating hinge support 32 on the right. The lower right side of the transparent acrylic plate 34 on the left gradually flattens the document to the right, while the lower left side of the transparent acrylic plate 34 on the right gradually flattens the document to the left until the lower surface of the transparent acrylic plate 34 is completely attached to the document. At this time, the document is in a flat state.

[0030] The de-shaping and de-crease mechanism 3 also includes telescopic rods 36, levers 37, and return springs 39. The telescopic rods 36 are symmetrically fixed to the lower surface of the upper and lower movable plates 2. The telescopic ends of the two telescopic rods 36 are respectively fixedly connected to levers 37. The left side of the front side of the front lever 37 is fixedly connected to the rear end of the front lever 38, and the right side of the rear side of the rear lever 37 is fixedly connected to the front end of the rear lever 38. The upper surfaces of the two levers 37 are respectively fixedly connected to return springs 39. The upper ends of the two return springs 39 are fixedly connected to the lower surface of one of the upper and lower movable plates 2. The two return springs 39 are respectively movably sleeved with the outer arc surface of the telescopic rods 36 located on the same side. The lower ends of the two levers 37 are respectively fixedly connected to pressure plates 4. During this period, the two pressure plates 4 will press the middle of the document back and forth, and then the pressure plates 4 will no longer move downward. When the two telescopic rods 36 retract, the two return springs 39 will also retract. (After long-term use, the return springs 39 will inevitably experience a decrease in elastic potential energy. When it is necessary to replace the return springs 39, the connection between the lever 37 and the telescopic rod 36 needs to be manually disassembled. Then, the return spring 39 is removed, and the new return spring 39 is inserted into the outer arc surface of the telescopic rod 36. The upper and lower ends of the return spring 39 are then inserted into the positioning holes drilled on the upper surface of the lever 37 and the lower surface of the upper and lower moving plate 2, respectively. Then, the pin is passed through the hole in the mounting plate and then through the center hole at the end of the connecting section of the return spring 39 (if the return spring 39 does not have a center hole, a connecting piece with a hole can be welded to the end of the spring to complete the replacement). The transverse slide 35 is then moved by the lever 38 to complete the operation. After that, the above steps are repeated in reverse to send out the document.

[0031] The working principle of the intelligent document collection terminal for RPA processes provided by this utility model is as follows: When the intelligent document collection terminal is needed, the interface of the external controller can be inserted into the external interface 8 to realize the external controller controlling the collection terminal. Alternatively, the document collection terminal can be controlled by adjusting the controller 9. At this time, the staff can place the document that needs to be collected onto the conveyor belt 10, and then adjust the conveyor belt 10 to move the document on the conveyor belt towards the center until it moves to the bottom of the industrial camera 5. At this time, adjust the controller 9, and the industrial camera 5 will operate. The industrial camera 5 will transmit the real-time image captured by the industrial camera 5 to the controller 9. When the controller 9 determines that the document in the image has moved to the bottom, it can adjust the controller 9 to extend the telescopic end of the linear driver 72, thereby pushing the upper and lower moving plate 2 to move downward by a specified length. During this period, the two pressure plates 4 will press the document together. In the middle, the pressure plate 4 stops moving downwards, and the two telescopic rods 36 retract. At this time, the two return springs 39 retract and move the transverse slide 35 through the lever 38. This causes the left rotating plate 33 to rotate counterclockwise at the hinge point of the left fixed hinge support 31 and the left rotating hinge support 32, while the right rotating plate 33 rotates clockwise at the hinge point of the right fixed hinge support 31 and the right rotating hinge support 32. The lower right side of the left transparent acrylic plate 34 gradually smooths the document to the right, while the lower left side of the right transparent acrylic plate 34 gradually smooths the document to the left until the lower surface of the transparent acrylic plate 34 is completely pressed against the document. At this time, the document is in a flat state. The controller 9 is turned on to perform supplementary lighting. The industrial camera 5 can then collect the document information captured by the camera. After the operation is completed, the above steps are repeated in reverse to send the document out.

[0032] It is worth noting that the controller 9 disclosed in the above embodiments uses a single-chip microcomputer, specifically the S7-200. The industrial camera 5, the light 6, the linear driver 72, and the conveyor belt 10 can be freely configured according to the actual application scenario. It is recommended that the industrial camera 5 be an HD-VCL200 industrial camera, the light 6 be a conventional LED camera, the linear driver 72 be a PD204L150 model motor linear driver, and the conveyor belt 10 be a conventional electric roller conveyor. The controller 9 controls the operation of the light 6, the linear driver 72, and the conveyor belt 10 using methods commonly used in the prior art.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
