Description

Technical Field

[0001] This invention relates to the field of office automation equipment technology, specifically to an integrated device for automatic verification and stamping of financial reimbursement documents. Background Technology

[0002] In corporate financial management, original documents such as invoices and employee expense reports must undergo two rigid steps before being entered into the accounting system: "authentication verification" and "affixing of the accounting seal." Traditional methods heavily rely on manual visual inspection of invoice headers, tax numbers, logical relationships between amounts, and the physical integrity of the documents before manually affixing the seal. This method is not only inefficient but also carries the risk of non-compliant documents being mistakenly stamped and filed due to fatigue or oversight.

[0003] With the development of OCR technology and artificial intelligence, financial automation devices have emerged in the existing technology. For example, Chinese Patent Publication No. CN110001224B discloses an automated device for large-scale document stamping and verification, and Chinese Patent Publication No. CN205202495U discloses an automatic document stamping device. Through in-depth analysis of the existing technology, the following defects have been found in the above devices: 1. Lack of hardware-level mandatory interlocking between verification and stamping: The verification and stamping modules of the existing device are physically independent, and the order of the workflow is controlled only by software signals. In the event of software failure, signal interference, or forced bypass, documents that fail verification may still be mistakenly stamped and enter the archiving process, posing a serious compliance loophole. 2. Limited verification dimensions: Most existing devices only perform OCR recognition and comparison on the text information on the tickets, lacking the ability to comprehensively examine the physical integrity of the tickets (such as alteration, scratching, damage, splicing) and anti-counterfeiting features (such as ultraviolet fluorescent ink, infrared anti-counterfeiting marks, and QR code authenticity), making it difficult to identify problematic tickets that have been physically forged. 3. The stamps need to be dipped in ink manually, resulting in insufficient automation: Most existing automatic stamping devices require manual replenishment of ink or replacement of the ink pad periodically. The ink-dipping action lacks an integrated design with the verification and stamping actions, which affects the efficiency of continuous operation.

[0004] Therefore, there is an urgent need for an integrated device that can establish a mandatory association between verification and stamping actions at the physical structure level, while also possessing multi-dimensional document authenticity verification capabilities and automatic ink application functions. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: According to an embodiment of the present invention, an integrated device for automatic verification and stamping of financial reimbursement documents includes an operating platform, a frame, a dual-modal actuator, and a control unit. The frame has a hollow structure and is vertically fixed to the top surface of the operating platform; The dual-modal actuator includes a telescopic drive assembly, a rotary drive assembly, and a dual-station support; the telescopic drive assembly is vertically fixed to the top surface of the operating platform and located in front of the frame; the rotary drive assembly is located at the top of the telescopic drive assembly; the dual-station support is fixed to the rotating shaft of the rotary drive assembly, and a multi-dimensional verification mechanism and a stamp clamping unit are fixed on the dual-station support. The control unit is located inside the frame and is communicatively connected to each component of the dual-mode actuator, including a controller and an audible and visual alarm.

[0006] Furthermore, the telescopic drive assembly is an electric push rod or a cylinder, and the rotary drive assembly is a stepper rotary motor.

[0007] Furthermore, the dual-station support is a rigid support in the shape of an "I", and the multi-dimensional verification mechanism and the seal clamping unit are respectively installed at both ends of the dual-station support, with the working axes of the multi-dimensional verification mechanism and the seal clamping unit coinciding.

[0008] Furthermore, the multi-dimensional verification mechanism includes an OCR information recognition module, a physical integrity detection module, and an anti-counterfeiting verification module, which are used to comprehensively verify the reimbursement documents.

[0009] Furthermore, the physical integrity detection module includes a high-resolution line scan camera and an image processing unit. The high-resolution line scan camera is used to acquire full-frame high-definition images of the expense report, and the image processing unit is used to identify whether the report has been altered, scratched, damaged, or spliced ​​through edge detection algorithms and grayscale analysis algorithms.

[0010] Furthermore, the anti-counterfeiting verification module includes an ultraviolet light source, an infrared light source, a fluorescence sensor, and a QR code scanner. The ultraviolet light source and the infrared light source are used to illuminate the surface of the document, the fluorescence sensor is used to detect the anti-counterfeiting fluorescent ink on the document, and the QR code scanner is used to scan the QR code on the document and verify its authenticity and validity.

[0011] Furthermore, the stamp clamping unit includes a base, a limiting block, and a locking bolt. The limiting block is located inside the base, and the locking bolt passes through the frame of the base and is fixedly connected to the limiting block.

[0012] Furthermore, the top of the frame is provided with an ink pad, which has an opening downwards receiving groove for detachably fixing the ink pad box.

[0013] Furthermore, the opening position of the inkpad seat matches the position of the bottom surface of the stamp when the rotary drive assembly rotates the stamp clamping unit to the top of the vertical direction of the dual-station bracket; the distance between the multi-dimensional verification mechanism and the rotating shaft of the rotary drive assembly is less than the distance between the stamp and the rotary drive assembly 32, so that when the rotary drive assembly rotates the multi-dimensional verification mechanism to the top of the vertical direction of the dual-station bracket, the multi-dimensional verification mechanism does not contact the inkpad.

[0014] Furthermore, the control unit is configured as follows: In the initial state, the telescopic drive assembly is in the extended position, the dual-station bracket is in the verification position, that is, the multi-dimensional verification mechanism is close to the bottom end of the dual-station bracket on the operating platform, and the stamp clamping unit clamps the stamp and dips it into the ink pad; when the verification is passed, the controller controls the rotary drive assembly to drive the dual-station bracket to rotate, switching the dual-station bracket to the stamping position, that is, the stamp clamping unit is close to the bottom end of the dual-station bracket on the operating platform, and controls the telescopic drive assembly to retract, driving the stamp clamping unit to advance towards the operating platform to complete the stamping; when the verification fails, the controller at least prohibits the rotary drive assembly from operating, keeps the stamp clamping unit at a safe height isolated from the operating platform, and the light of the audible and visual alarm flashes and sounds an alarm.

[0015] The advantages of this invention compared to the prior art are: 1. Through the action logic of "extend for verification - rotate to switch - retract for stamping", rotation is prohibited when verification fails and the telescopic rod does not retract. The stamp is always kept at a safe height away from the document, which avoids accidental stamping from a physical structure perspective and greatly improves the compliance of financial operations. 2. It integrates three major modules: OCR information recognition, physical integrity detection, and anti-counterfeiting feature verification. It can not only verify the authenticity of the text information on the invoice, but also identify physical forgery traces such as alteration, scratching, damage, and splicing, as well as anti-counterfeiting features such as ultraviolet fluorescent ink, infrared markings, and QR codes, thus constructing a more complete invoice review system. 3. By utilizing the top position of the dual-station bracket in conjunction with the inkpad, the stamp automatically maintains an ink-dipped state at the calibration station, which saves manual operation and ensures physical isolation between the calibration mechanism and the inkpad through the position design, thus avoiding contamination. 4. The working axis of the multi-dimensional verification mechanism coincides with that of the seal clamping unit to ensure accurate stamping position. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Example 1: Normal stamping process after verification According to an embodiment of the present invention, an integrated device for automatic verification and stamping of financial reimbursement documents is provided, such as... Figure 1 , Figure 2As shown, specifically, it includes a rectangular operating platform 1, with a hollow frame 2 vertically fixed to the rear side of the top surface of the operating platform 1. A telescopic drive assembly 31 of a dual-mode actuator 3 is vertically fixed to the top surface of the operating platform 1 in front of the frame 2. The telescopic drive assembly 31 uses an electric push rod, and a stepper rotary motor is fixed to the top of its telescopic rod as a rotary drive assembly 32. The rotating shaft of the rotary drive assembly 32 is horizontally set and perpendicular to the telescopic drive assembly 31, and its end is fixedly connected to an aluminum alloy "I"-shaped double-station bracket 33. A multi-dimensional verification mechanism 4 and a stamp clamping unit 5 are respectively installed at both ends of the double-station bracket 33, and their working axes are parallel to each other.

[0020] like Figure 3 As shown, the base 51 of the seal clamping unit 5 has a pre-installed corporate accounting circular seal. The operator places the seal into the base 51, rotates the locking bolt 53, pushes the limiting block 52 close to the inner wall of the base 51 and clamps the outer wall of the seal to complete the fixation; a standard circular inkpad box has been inserted into the inkpad seat 21 at the top of the frame 2.

[0021] The initial state of the device is as follows: the telescopic drive component 31 is in the extended position, the left end (multi-dimensional verification mechanism 4) of the dual-station bracket 33 is located below, close to the document placement area on the operation platform 1; the right end (stamp clamping unit 5) is located above, and the bottom surface of the stamp is in contact with the ink pad surface in the ink pad 21, maintaining the ink-dipped state.

[0022] The finance staff places a VAT invoice submitted by an employee flat in the designated area on the operating platform 1. The controller 61 of the control unit 6 located inside the rack sends a start command to the multi-dimensional verification mechanism 4. Figure 4 As shown, the three modules work sequentially: (1) The OCR information recognition module 41 scans the invoice image and extracts fields such as invoice code, number, invoice date, amount, tax amount, and buyer's name. It then compares the data with the tax system interface in real time to confirm the authenticity and consistency of the information. (2) The high-resolution line scan camera 421 of the physical integrity detection module 42 performs a full-frame scan of the invoice, and the image processing unit 422 runs the edge detection algorithm and grayscale analysis algorithm. No traces of alteration, scratching, damage or splicing are found. (3) The anti-counterfeiting verification module 43 sequentially activates the ultraviolet light source 431 and the infrared light source 432 to irradiate the surface of the invoice. The fluorescence sensor 433 detects the normal anti-counterfeiting fluorescent ink reaction. The QR code scanner 434 reads the QR code on the invoice and verifies that it is genuine and valid.

[0023] When all three checks pass, the controller 61 sends a pulse signal to the rotary drive assembly 32, causing the stepper motor to rotate precisely 180 degrees, and the left and right ends of the dual-station bracket 33 are interchanged. Figure 5 As shown, the stamp holding unit 5 on the right end rotates to the bottom (stamping station), and the multi-dimensional verification mechanism 4 on the left end rotates to the top (not in contact with the ink pad).

[0024] After rotating to the correct position, the controller 61 controls the telescopic drive assembly 31 to retract, the telescopic rod retracts downward, and drives the entire seal clamping unit 5 to move towards the operating platform 1. The bottom surface of the seal passes through the reserved space and presses against the invoice stamping area to complete the stamping. After the stamping is completed, the telescopic drive assembly 31 extends and resets again, bringing the seal clamping unit 5 back to the upper ink-dipping position.

[0025] The finance staff took the stamped invoice, completing the task.

[0026] During daily continuous use of the device, it is powered by an external power source. After each stamping is completed and the telescopic drive component 31 extends and resets, the stamp clamping unit 5 returns to the top of the dual-station bracket 33, and the bottom surface of the stamp comes into contact with the ink pad surface in the ink pad holder 21, automatically replenishing the ink and preparing for the next stamping.

[0027] When the dual-station bracket 33 is in the stamping station (stamp end is below), the multi-dimensional verification mechanism 4 is located at the top. Since the distance between the multi-dimensional verification mechanism 4 and the rotating drive component 32 is less than the distance between the stamp and the rotating drive component 32, the multi-dimensional verification mechanism 4 can maintain a safe distance from the ink pad and will not come into contact with the ink pad, thus fundamentally avoiding the risk of the optical lens and sensor being contaminated by the ink pad.

[0028] Example 2: Physical Blocking and Alarm Procedures for Failed Verification like Figure 6 As shown, if the invoice submitted by the employee is abnormal—for example, the image processing unit 422 detects obvious grayscale abnormality in the invoice amount column, and the algorithm determines that it is a scratch and refill mark; or the fluorescence sensor 433 does not detect the expected anti-counterfeiting fluorescence reaction.

[0029] If the comprehensive judgment and verification by the controller 61 fails, the controller 61 will not send any action command to the rotary drive component 32, the stepper motor will remain locked, the dual-station bracket 33 will maintain its initial posture, the stamp clamping unit 5 will always be at the top safe height, and will be physically isolated from the documents on the operating platform 1. The telescopic drive component 31 will also not perform a retraction action.

[0030] At the same time, the controller 61 triggers the audible and visual alarm 62, which flashes a red light and sounds a buzzer alarm to alert the finance staff that there is an anomaly in the document. The finance staff then take the problematic document away for manual review, and the device remains in standby mode to wait for the next document.

[0031] 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.
