[0016] This solves the problem of relying on manual counters for expense reimbursement, saves manpower, eliminates the inevitable errors that occur in the tedious manual operation process, reduces the labor intensity of manual workers, and saves time.

[0017] This device employs a single-sheet fast-adsorption and grabbing photographing mechanism, easily handling both single sheets and sheets with attached receipts, without grabbing multiple sheets at once or tearing or ripping attached receipts. Each transmission component uses a synchronous belt and slider structure for movement, offering advantages such as fast response, low noise, and high repeatability. The document clamping device uses a screw stepper motor with linear bearings for positioning and guidance, ensuring secure clamping regardless of the number of documents. The document transfer device accurately delivers documents to designated locations based on system commands.

[0018] The nighttime self-service document processing mode saves time during the workday, allowing more people to submit expense reports, avoiding long queues, and reducing the time wasted by manual staff walking back and forth from the counter to the storage area. Attached Figure Description

[0042] The present invention will now be described in further detail with reference to the accompanying drawings.

[0043] Combination Figure 1 , Figure 2 , Figure 3 As shown, the image intelligent acquisition document delivery cabinet includes a cabinet body 4. The outer frame of the cabinet body 4 is made of cold-rolled steel plate and coated with environmentally friendly plastic powder. The bottom of the cabinet body 4 is connected to a fuma wheel 7, and the top of the cabinet body 4 is connected to a monitoring component 1. The rear side of the cabinet body 4 is provided with a rear inspection door 10, and the front side of the cabinet body 4 is provided with a front left inspection door 5 and a front right inspection door 9. Below the front left inspection door 5 is a document mailing and collection door 6. The top of the cabinet body 4 is provided with a self-service operation touch screen 3 and a document placement slot 12, both of which are set on the top inclined table panel for convenient user operation. Above the placement slot is a document QR code scanning and delivery slot 8. The cabinet body 4 is provided with a face recognition camera 2 and an ID card swiping area 11 near the self-service operation touch screen 3.

[0044] The cabinet 4 is equipped with a rack, a system control box 10, a document storage area 11, a document placement door mechanism 100, a document frame lifting mechanism 200, a document grabbing mechanism 300, a document grabbing and moving mechanism 400, a high-speed scanner module 500, a document clamping mechanism 600, a document transfer device 700, and a document storage mechanism 800.

[0045] The system control box 10, document storage area 11, and document grasping and moving mechanism 400 are fixed to the right side panel inside the cabinet 4 by bolts. The document grasping and moving mechanism 400 is located above the system control box 10 and document storage area 11. The document grasping and moving mechanism 400 is connected to the document grasping mechanism 300. The document placement door mechanism 100 is welded to the top panel of the cabinet 4 corresponding to the document placement opening 12. The document frame lifting mechanism 200, high-speed scanner module 500, and document storage mechanism 800 are fixed to the frame by bolts. The document frame lifting mechanism 200 and high-speed scanner module 500 are located on the side close to the document grasping mechanism 300. The document transfer device 700 is fixed to the bottom plate inside the cabinet 4 by bolts. The document clamping mechanism 600 is connected to the document transfer device 700.

[0046] The working principle of the delivery slot door mechanism, such as Figure 4 As shown:

[0047] The document storage compartment door 101 is fixed to the slider of the door moving linear guide rail 106 with screws. The slider and the document storage compartment door 101 are connected to the synchronous belt of the door drive synchronous belt mechanism 105 with screws. The synchronous belt is driven to move left and right by the door moving drive stepper motor 111. The door drive synchronous belt mechanism 105, the door moving linear guide rail 106 and the door moving drive stepper motor 111 are fixed to the door drive system mounting bracket 110 with bolts. The anti-pinch sensor 102 is fixed to the door frame 104 with bolts at the front and back. It forms a photoelectric state through the anti-pinch light-transmitting plate 103. The QR code reader 109 is fixed to the reader mounting bracket 108 with screws. The document QR code scanning port 107 is located directly below the reader mounting bracket 108 to facilitate accurate scanning of the QR code. The reader mounting bracket 108, the door frame 104 and the anti-pinch light-transmitting plate 103 are connected by welding.

[0048] The person submitting the expense report uses the face recognition camera 2 and the self-service touch screen 3 on the cabinet 4 to place the document into the QR code scanning port 107 for recognition and scanning. After the above operation is correct, the document placement door 101 will move to the left. The door movement drive stepper motor 111 drives the door drive synchronous belt mechanism 105 to move parallel along the door movement linear guide rail 106 until the document placement door 101 is fully open.

[0049] The operator places the document into the document placement box 203 inside the document placement compartment door 101. The document placement compartment door 101 will automatically close within a set time. If a hand or other object appears within the closing range of the document placement compartment door 101 during the closing process, the document placement compartment door 101 will automatically retract to the fully open state. The document placement compartment door 101 will automatically close after the obstacle is removed to prevent pinching injuries.

[0050] The working principle of the document lifting mechanism, such as Figure 5 As shown:

[0051] The lifting drive stepper motor 201 is bolted to the motor mounting bracket of the synchronous belt linear module 202, and drives the synchronous belt of the synchronous belt linear module 202 through a coupling. The lifting slider 206 is connected to the synchronous belt with a special pressure plate. When the synchronous belt moves, the lifting slider 206 moves together with the synchronous belt. The infrared sensor 204 is fixed to the base plate of the document placement frame 203 with screws to determine whether there is a document in the document placement frame 203. The document placement frame 203 is bolted to the document frame fixing bracket 205, and the document frame fixing bracket 205 is bolted to the lifting slider 206. In this way, when the synchronous belt linear module 202 moves, the document placement frame 203, the infrared sensor 204, the document frame fixing bracket 205, and the lifting slider 206 will move up and down together. Finally, the entire mechanism is bolted to connect the synchronous belt linear module 202 to the frame inside the cabinet 4.

[0052] Before the document placement compartment door 101 is opened, the document placement frame 203 will rise below the document placement compartment door 101 to wait for the document to be placed in. After the document is placed in the document placement frame 203, the document placement compartment door 101 will close, and the document placement frame 203 will automatically descend to the designated position and stop, waiting for the document grabbing mechanism 300 and the high-speed scanner module 500 to perform the next action.

[0053] Once the document grabbing mechanism 300 has finished grabbing the last document, the infrared sensor 204 will send a signal to the system control box 10 to complete the entire document grabbing process.

[0054] The working principle of a document capture mechanism, such as Figure 6-8 As shown:

[0055] Figure 6 The diagram shown is a schematic of the wind deflector 308 when it is open. The wind deflector 308 is opened by the push and pull of the electric push rod 304 through the rotation of the hinge 307 of the wind deflector 308. When the paper is gripped, the electric push rod 304 retracts, opens the air outlet 306 of the fan 303, closes the air inlet 305 of the top cover, and the paper and the gripping negative pressure box 301 come into contact with the blocking vent 302, so that negative pressure is quickly generated in the gripping negative pressure box 301, and the paper is firmly sucked onto the bottom plate of the gripping negative pressure box 301.

[0056] Figure 7 The diagram shown is a schematic of the wind deflector 308 when it is closed. The wind deflector 308 is closed by the push and pull of the electric push rod 304 through the rotation of the hinge 307 of the wind deflector 308. When the paper is released, the electric push rod 304 extends and closes the air outlet 306 of the fan 303, while opening the air inlet 305 of the top cover to allow outside air to enter the gripping negative pressure box 301. The rotation of the fan blades of the fan 303 causes a large amount of air to be quickly drawn into the gripping negative pressure box 301, breaking the negative pressure state and allowing the paper to be smoothly released from the bottom plate of the gripping negative pressure box 301.

[0057] Figure 8 The diagram shows the arrangement of the vent holes on the bottom plate of the negative pressure gripping box 301. The reasonable arrangement allows for the smooth gripping of single sheets of paper and sheets with receipts attached. The moderate suction force ensures that only one sheet is gripped at a time, preventing the gripping of multiple sheets.

[0058] The working principle of the document grabbing and moving mechanism, such as Figure 9 As shown:

[0059] The document gripping mechanism 300 is bolted to the gripping mechanism mounting bracket 401. The gripping mechanism mounting bracket 401 is bolted to the slider of the gripping mechanism vertical motion module 402. The slider and the timing belt are connected by a special pressure plate. The vertical drive stepper motor 403 of the gripping mechanism vertical motion module 402 is bolted to the motor mounting bracket of the gripping mechanism vertical motion module 402. The gripping mechanism vertical motion module 402 is driven by a coupling to move the accessories up and down. The gripping mechanism horizontal motion module 404 is bolted to the right side plate of the cabinet 4. The horizontal drive stepper motor 405 of the gripping mechanism horizontal motion module 405 is bolted to the motor mounting bracket of the gripping mechanism horizontal motion module 404. The horizontal drive stepper motor 405 drives the timing belt through a coupling. The timing belt and the slider of the gripping mechanism horizontal motion module 404 are connected by a special pressure plate. The gripping mechanism vertical motion module 402 is bolted to the slider of the gripping mechanism horizontal motion module 404.

[0060] After the document placement frame 203 descends to its position, the high-speed scanner module 500 takes position to measure distance and take pictures. Then, the document grabbing mechanism 300 first moves vertically to the set upper limit position, and then moves horizontally above the document placement frame 203. The vertical movement module 402 of the grabbing mechanism descends above the document, the fan 303 turns on, and the baffle 308 opens to grab the document and rise to the set position. The horizontal movement module 404 of the grabbing mechanism moves to above the document temporary storage area 20. The vertical movement module 402 of the grabbing mechanism closes the air outlet 306 through the electric push rod 304, and the document falls into the document temporary storage area 20. One cycle is completed until the last document is grabbed.

[0061] The working principle of a document scanner module, such as Figure 10 As shown:

[0062] The rotary drive stepper motor 501 is bolted to the document scanner module mounting bracket 503, which is fixed to the frame inside the cabinet 4. Two sets of rotation angle sensors 502 are fixed to the document scanner module mounting bracket 503 with two nuts. The rotation angle of the mounting plate 504 is changed by moving its position. The mounting plate 504 is bolted to the transition flange of the rotary drive stepper motor 501. The document scanner 505 is fixed above the mounting plate 504 with screws. The supplementary light 506 is fixed below the mounting plate 504 with screws to provide a light source for the document scanner 505 when taking pictures.

[0063] The document placed in the document placement frame 203 is illuminated and photographed, and the document gripping mechanism 300 is moved vertically up, down, left, and right to avoid being moved by the left and right swing angle.

[0064] Figure 10 The image shows the avoidance state. Rotate to the left by a set angle to reach the preset photo position, and return to the starting position after each photo is taken. Figure 10 The location is determined by the movement trajectory of the document grabbing mechanism 300, allowing for positional avoidance.

[0065] The working principle of the document clamping mechanism, such as Figure 11 As shown:

[0066] The document clamping movable clamp 601 is fixed on the guide post fixing seat of the movable clamping plate guide shaft module 602 for fixing the guide post. There are two sets of movable clamping plate guide shaft modules 602, one on each side. The output end of the movable clamping plate screw stepper motor 603 is fixed on the document clamping movable clamp 601. The movable clamping plate screw stepper motor 603, the linear bearing of the movable clamping plate guide shaft module 602, and the movable clamping plate limit sensor 604 are fixed on the document clamping fixed clamp 605 to control the orientation and upper limit stop position of the movable document clamp 601. The holding clamp 605 is fixed to the slider of the clamp moving linear guide module 610 with screws. The slider and the synchronous belt of the clamp moving synchronous belt module 609 are fixed together. When the synchronous belt moves, it will drive the entire clamp system to move back and forth at the same time. The clamp moving front limit sensor 611 is used to control the stop position of the front end of the clamp system through position adjustment. The power of the clamp moving synchronous belt module 609 is provided by the clamp moving back and forth drive stepper motor 608. The entire clamp system is fixed on the clamping module fixing slot 607.

[0067] Figure 11 The clamping mechanism is shown in the open and zero position. During operation, the clamping plate moves back and forth, driving the stepper motor 608 to move the clamping plate. The synchronous belt module 609 sends the clamping plate module to the designated position at the front. The clamping plate screw stepper motor 603 works to clamp the document between the two clamping plates. Then, the clamping plate moves back and forth, driving the stepper motor 608 to move backward to the rear limit position.

[0068] The working principle of document transfer device, such as Figure 12 As shown:

[0069] The horizontal travel track 701 serves as the reference for the entire document transfer device 700. The horizontal travel track 701 is bolted to the base plate of the cabinet 4, making the entire travel system an integral part of the cabinet 4. The horizontal travel mechanism is supported by two sets of horizontal linear guide rail modules 704, with a total of four sliders in the two modules. Horizontal travel is driven by a horizontal travel drive stepper motor 707 in conjunction with a horizontal travel rack 705 to achieve horizontal left and right movement. Horizontal travel limit sensors 703 are installed at both ends of the horizontal travel track 701, and a horizontal zero-position sensor 703 is installed on the far right. Adjusting the positions of these sensors controls the left and right stop positions of the horizontal travel mechanism and the device's return to zero. The vertical travel module fixing plate 706 is bolted to the sliders of the horizontal linear guide rail module 704. The vertical walking module mounting bracket 708 is bolted to the vertical walking module fixing plate 706. The vertical walking track 709 is mounted on the vertical walking module mounting bracket 708 in a vertical state. The vertical walking linear guide module 710 is bolted to the vertical walking track 709, with one set on each side. Each set has a slider. The document clamping mechanism 600 is bolted to the slider of the vertical walking linear guide module 710 through a transition plate. The vertical movement of the document clamping mechanism 600 is accomplished by the vertical walking stepper motor 711 driving the vertical walking synchronous belt module 712. The synchronous belt is fixed on the transition plate. The vertical walking limit sensor 713 is fixed to the side of the vertical walking track 709. The vertical movement position of the document clamping mechanism 600 is determined by adjusting the position of the sensor.

[0070] The document clamping mechanism 600 moves to the document temporary storage area 20 via the horizontal and vertical walking mechanisms. The document clamping mechanism 600 opens and extends forward to the document temporary storage area 20. After clamping the documents in the document temporary storage area 20, the document clamping mechanism 600 retracts to the rear limit position. The transfer mechanism moves the document clamping mechanism 600 to the designated position according to the signal sent by the system control box 10. The document clamping mechanism 600 extends forward to the front limit position. The clamping movable plate releases and places the documents on the document storage fixing rack 802. The clamping mechanism retracts to the rear limit position and returns to the zero position to wait for the next transfer process.

[0071] The working principle of a document storage mechanism, such as Figure 13 As shown:

[0072] The document and receipt mailing storage area 801 is welded from multiple steel plates and fixed to the bottom plate of cabinet 4 with bolts. The document storage fixing rack 802 is fixed to the fixing rack support plate 804 with screws. The fixing rack support plate 804 is fixed to the frame of cabinet 4 with bolts. The cabinet power supply module 803 is fixed to the bottom plate of cabinet 4 with bolts. The document storage fixing rack 802 can be spliced ​​into different numbers of arrangements as needed to facilitate the placement and storage of documents.

[0073] After the photos are taken, the documents are sent to the designated location for storage by the document transfer device 700 according to the system instructions. According to the system instructions, the document transfer device will take out the reviewed documents from the storage rack at a specific time and put them into the document mailing storage area 801. Mailing staff can open the document mailing retrieval door 6 by using a special password or ID scanning and facial recognition system. The staff can then take out the documents to be mailed and close the document mailing retrieval door 6 again.

[0074] In specific implementation, the operation steps of this invention are as follows:

[0075] 1. Self-service touchscreen;

[0076] 2. Click "Submit Document";

[0077] 3. Use a QR code reader to scan the QR code on the paper document;

[0078] 4. The backend server recognizes the QR code normally;

[0079] 5. Open the ticket delivery slot door (there is an anti-pinch sensor at the delivery slot to prevent your hand from being pinched when the ticket delivery slot door closes);

[0080] 6. The document placement box rises from its original position to the document delivery slot door (where the user places the paper document into the document placement box);

[0081] 7. The document delivery slot door is closed, and the document placement frame is lowered to a position parallel to the negative pressure grabbing box;

[0082] 8. The high-speed scanner camera rotates from the origin to the center of the document placement frame;

[0083] 9. The software starts the high-speed document scanner camera to capture image information of paper documents (and starts the fan at the same time);

[0084] 10. The document grabbing and moving mechanism moves from the origin to the document placement frame position;

[0085] 11. The document grabbing mechanism is moved down to a position parallel to the document placement frame;

[0086] 12. The electric push rod opens the fan outlet, generating negative pressure to attract a piece of paper document;

[0087] 13. After the document is captured, the document capturing mechanism moves upward and then moves horizontally to the origin (after reaching the origin, it moves downward, the electric push rod closes the fan outlet, and air enters the negative pressure box through the air inlet of the upper cover. The negative pressure is deactivated, and the document falls into the document temporary storage area).

[0088] 14. When there are multiple documents, repeat steps 9, 10, 11, 12, and 13 (so the fan stops after the documents are photographed and transferred. The bottom plate of the document placement frame is equipped with an infrared sensor, which stops grabbing when no paper is detected).

[0089] 15. The back-end document transfer device moves upward and horizontally from the origin position to the document temporary storage area position. Before the movement, the document clamping mechanism is opened.

[0090] 16. After the document clamping mechanism moves to the document temporary storage area, it closes to clamp the document. Then it moves up and down to the designated document storage rack. According to the delivery position issued by the system control box 10, the document is moved to the document storage rack. After the document clamping mechanism is aligned with the designated document storage rack, it extends forward into the document storage rack. The clamping mechanism releases the grippers and retracts the clamping mechanism. The document transfer device returns to the origin, and the delivery is completed.

[0091] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
