DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 5 , the present invention provides a technical solution:

[0027] An intelligent paper bill sorting and storage device for accounting purposes includes a housing 2 with a mounting platform at its center. A conveyor 3 is mounted on the mounting platform surface. A sorting device 6 is located at the end of the conveyor 3's travel. Drawers 11 are symmetrically positioned on either side of the mounting platform. A flattening device 10 is also located at the starting end of the conveyor 3. A camera 8 is located directly above the conveyor 3, on the inner side of the top wall of the housing 2. A computing module 7 is also located between the sorting device 6 and the housing 2. Camera 8 uses a commercially available OPENCV camera, which features a high-resolution optical lens and a fill light system for capturing images of paper bills. Computing module 7 uses a commercially available NVIDIA Jetson Xavier NX embedded AI computing module, which integrates an OCR engine and machine learning model to enable content recognition, classification, and anomaly detection for paper bills.

[0028] In the present invention, the conveying device 3 includes a first synchronous shaft 3-1 and a second synchronous shaft 3-3 arranged at the starting end and the end of the stroke, and the surfaces of the first synchronous shaft 3-1 and the second synchronous shaft 3-3 are connected to the conveyor belt 3-2, one end of the second synchronous shaft 3-3 is connected to a small gear 3-5, and the outer side of the small gear 3-5 is meshed with a large gear 3-4, and the large gear 3-4 is connected to the end of the driving shaft of the driving end of the second stepper motor 9-2. One end of the first synchronous shaft 3-1 is also connected to an idler gear 3-6 through a transmission gear.

[0029] In the present invention, the flattening device 10 comprises two counter-rotating rollers 10-3 located at the starting end of the conveyor 3. A drive shaft 10-2 extends through each roller 10-3. One end of the drive shaft 10-2 is connected to a meshing gear set 10-1. The gear set 10-1 comprises two meshing drive gears, one of which is aligned with the idler gear 3-6 and meshes with the idler gear 3-6. Infrared sensors are also located at the exits of the two rollers 10-3 to detect the flatness of the paper bills.

[0030] In the present invention, the sorting device 6 includes a mounting frame fixedly connected between the inner walls of the housing 2. A lead screw 5 is provided through the mounting frame. One end of the lead screw 5 is connected to a first stepper motor 9-1. A sliding block 6-1 is also threaded onto the lead screw 5. A servo 4 is symmetrically arranged at the bottom of the sliding block 6-1 near the end of the conveyor 3. A receiving plate 6-2 is connected to the rotating shaft between the two servos 4. The sliding block 6-1 is also slidably connected to the mounting frame. A support block 12 is also provided between the center of the bottom of the mounting frame and the surface of the mounting platform. The sliding block 6-1 is also provided with a Hall effect sensor for real-time detection of position deviation and triggering the calibration process.

[0031] In the present invention, first stepper motor 9-1, second stepper motor 9-2, and servo 4 are also electrically connected to computing module 7. Camera 8 utilizes a commercially available OPENCV camera, which has a high-resolution optical lens and a fill light system for capturing images of paper bills. Computing module 7 utilizes a commercially available NVIDIA Jetson Xavier NX embedded AI computing module, which integrates an OCR engine and machine learning model to achieve paper bill content recognition, classification, and anomaly detection. An OPENCV camera captures images of paper receipts in real time and transmits them to the NVIDIA Jetson Xavier NX embedded AI computing module via a USB 3.0 interface. This module integrates a GPU-accelerated OCR engine (such as Tesseract 5.0) and a customized machine learning model. It features a 6-core NVIDIA Carmel ARMv8.2 CPU and a 384-core Volta GPU, 8GB of LPDDR4x memory, and 16GB of eMMC storage. It supports USB 3.1, Gigabit Ethernet, GPIO, and CSI camera interfaces and is compatible with OPENCV cameras. OCR recognition technology is used to extract key information from paper receipts, such as the amount, date, and transaction party. The NVIDIA Jetson Xavier NX embedded AI computing module serves as the main controller, coordinating the movements of servo 4, first stepper motor 9-1, and second stepper motor 9-2. The action timing of the flattening device 10, the conveying device 3 and the sorting device 6 is adjusted according to real-time feedback. For example, the pressure of the flattening device 10 is adaptive to the thickness of the paper bill. When a paper jam or overload of the second stepper motor 9-2 is detected, an audible and visual alarm is triggered and the operation is suspended.

[0032] In the present invention, a baffle 1 is further provided on one side of the housing 2 near the starting end of the conveyor 3. The baffle 1 has an N-shaped structure, and an inlet is provided at the center of the baffle 1, which is connected to the starting end of the conveyor 3. The baffle 1 is made of a transparent acrylic plate, which facilitates real-time observation of the operating status inside the housing 2.

[0033] In the present invention, multiple dividers are arranged vertically and horizontally within each drawer 11. Adjacent dividers, as well as the dividers and drawers 11, are magnetically secured to each other. Each drawer 11 is equipped with multiple independent partitions, whose sizes are adjusted by the dividers to accommodate the size of paper receipts. Paper receipts are stored by category, and the partition labels are automatically synchronized with the electronic ledger. Keyword input, such as date or amount, is used in the accompanying software to locate the drawer 11 and partition where the paper receipt is located.

[0034] Example: Mixed paper bills are sequentially passed through the entrance at the center of the baffle 1, which is interconnected with the starting end of the conveyor 3. The paper bills are conveyed to the conveyor belt 3-2 by the two counter-rotating rollers 10-3 of the flattening device 10. During this process, the silicone rollers 10-3 apply pressure to eliminate wrinkles on the paper bills. Infrared sensors detect flatness. As the paper bills are conveyed from the starting end of the conveyor 3 to the end of the journey, the camera 8 captures the paper bill image. The calculation module 7 extracts the amount, date, and transaction party information, and compares and classifies them with the database.

[0035] When the paper bill is transmitted from the transmission device 3 to the end of the conveyor belt 3-2, the servo 4 drives the storage plate 6-2 to tilt upward at a certain angle to receive the paper bill, and then controls the first stepper motor 9-1 to operate so that the sliding block 6-1 moves along the screw 5 to the top of the corresponding drawer 11. The servo 4 drives the storage plate 6-2 to flip downward and send the paper bill into the partition in the designated drawer 11; the calculation module 7 generates an electronic ledger to record the storage location, key information and image copies of the paper bill, and supports Excel / PDF export.

[0036] In the case of abnormal processing, when the paper bill is blurred and the OCR recognition confidence is 85%, the calculation module 7 automatically triggers the retake mechanism of the camera 8. If it still fails, it triggers an audible and visual alarm and suspends operation, prompting manual intervention.

[0037] This device has efficient processing capabilities, strong compatibility and self-learning optimization functions, which can significantly improve accounting work efficiency and reduce manual error rates. It is suitable for high-intensity financial data processing scenarios.
