Description

Technical Field

[0001] This invention relates to the field of accounting document processing technology, and in particular to an accounting document processing system and method. Background Technology

[0002] Accounting documents mainly include cash payments, bank settlements, notes receivable, notes payable, deductible notes, accrual notes, and payment notes. They accurately reflect the financial activities of an enterprise and serve as feasible audit evidence. When processing these documents, accounting document processing equipment is typically used to improve processing efficiency. Existing technologies involved include:

[0003] 1. An accounting document processing device with publication number CN106357953B, wherein a controller controls a document transfer device to transfer a stack of documents pre-placed in a document placement assembly to a document flattening assembly one by one. After the document flattening assembly flattens the documents, the controller controls the document transfer device to transfer the flattened documents to a document scanning assembly for scanning each document. This invention can transfer and flatten documents one by one before scanning, improving the efficiency of document processing. This invention uses negative pressure adsorption for transfer, ensuring that documents are flattened and scanned one by one, thus improving the accuracy of document processing. Two document transfer devices are driven by the same lead screw. The system allows for simultaneous transfer of one document from the flattening position to the scanning position, while another document is transferred from the flattening position to the scanning position, thus improving document processing efficiency. Limit switches and lead screws enhance accuracy. However, in this patent document, the document only describes lateral movement of the document. Therefore, before placing the document on the document placement component, the operator must first arrange the document with the content side facing up so that the scanning component can scan the document content. This results in a significant workload for the operator. Furthermore, the document remains exposed throughout the process, compromising both document security and the confidentiality of its content, thus affecting usability.

[0004] 2. A financial accounting document processing device with publication number CN215792757U has the following key technical features: it includes a storage box with a storage opening at the top. A flattening component is provided on the inner wall of the opening of the storage opening. The flattening component is right-angled with its intersection facing the left side of the storage opening, and the right-angle opening of the flattening component facing the right side of the storage opening. A flattening belt is rotatably provided at both the upper and lower ends of the storage opening. The upper flattening belt rotates counterclockwise, and the lower flattening belt rotates clockwise. However, this patent document can only realize the horizontal transmission of documents and cannot realize the flipping of documents, thus its function is limited.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Summary of the Invention

[0006] The purpose of this invention is to solve the above problems. The technical solution of this invention to achieve the above purpose is: an accounting invoice processing system, including a base and a cover, wherein a processing structure is installed on the base and the cover is installed on the processing structure;

[0007] The processing structure includes a support base mounted on a base. A fixed ring frame is mounted on the support base, and the fixed ring frame has a protrusion. Two retaining rings are symmetrically arranged at the opening of the fixed ring frame. A rotating ring is movably mounted on the fixed ring frame, and the rotating ring has several meshing teeth arranged in a circular array.

An inlet is mounted on the sidewall of the barrier at one end of the transmission unit, and a picking unit is mounted on the sidewall of the barrier at one end of the inlet. An outlet is mounted on the sidewall of the barrier at the other end of the transmission unit. A storage unit is mounted on the base.

[0008] The flipping power unit includes a flipping motor, which is mounted on the side wall of the protrusion, and the drive end of the flipping motor moves through the protrusion. A gear is fitted on the drive end of the flipping motor, and the gear meshes with a plurality of meshing teeth.

[0009] The transmission unit includes a U-shaped seat, which is installed on the telescopic end of the spacing adjustment cylinder. Two rotating rods are movably inserted into the U-shaped seat, and a conveyor belt is fitted on the two rotating rods. A conveyor motor is installed on one of the two rotating rods.

[0010] Two telescopic rods are installed between the rotating ring and the U-shaped seat.

[0011] The inlet includes an input slot sleeve, which is inserted into the enclosure and located at the center of the fixed frame. Two mounting slots are symmetrically opened on the enclosure, and a centering cylinder is installed in each of the two mounting slots. The telescopic end of the centering cylinder is movably inserted into the input slot sleeve, and a moving strip is installed on the telescopic end of the centering cylinder. The moving strip matches the inner wall of the input slot sleeve. An extension plate is provided at one end of the input slot sleeve, and a recognition camera is embedded in the center of the upper wall of the extension plate.

[0012] The part-retrieving unit includes a support rod, which is installed on the side wall of the enclosure. A lead screw module is installed on the support rod, and a connecting frame is installed on the moving end of the lead screw module. A fixing plate is installed on one end of the connecting frame. Two side cylinders are installed on the lower wall of the fixing plate, near the enclosure. Each of the two side cylinders has a side suction nozzle installed on its telescopic end. Two opposite side cylinders are installed on the lower wall of the fixing plate, away from the enclosure. Each of the two opposite side cylinders has an opposite side suction nozzle installed on its telescopic end. A part-holding box is installed on the side wall of the enclosure.

[0013] The scanning unit includes a mounting bracket mounted on a base. A movable cylinder is mounted on the side wall, and a scanning camera is mounted on the telescopic end of the movable cylinder. An image processing component is connected to the scanning camera.

[0014] The image processing component includes an image data processing module connected to a scanning camera, a data conversion module connected to the image data processing module, and a data storage module connected to the data conversion module.

[0015] The outlet includes a through hole, which is formed on the side wall of the enclosure. An avoidance cylinder is installed on the side wall of the enclosure. A connecting plate is installed on the telescopic end of the avoidance cylinder. A discharge slot sleeve is installed on the connecting plate. The discharge slot sleeve is movably inserted into the through hole. One end of the discharge slot sleeve has an inclined surface. An avoidance groove is formed on the inner bottom surface of the discharge slot sleeve. A conveyor is installed on the avoidance groove. The upper wall surface of the conveyor and the inner bottom surface of the discharge slot sleeve are on the same plane.

[0016] The storage unit includes an electric turntable mounted on a base. A lifting cylinder is mounted on the electric turntable, and a placement panel is mounted on the telescopic end of the lifting cylinder. Several storage components are mounted on the placement panel in a circular array.

[0017] The storage components include two clamping cylinders, which are symmetrically mounted on the placement panel. Each clamping cylinder has a clamping plate installed at its telescopic end. A storage box is movably placed on the placement panel. The clamping plates are movably attached to the storage box. A sealing cylinder is installed on the side wall of the storage box, and a sealing cover is installed on the sealing cylinder.

[0018] An accounting document processing method includes the following steps:

[0019] Step 1: Place a large number of accounting documents horizontally in the storage box. One side cylinder and the opposite side cylinder extend, and one side suction nozzle and the opposite side suction nozzle pick up one accounting document. Then, one side cylinder and the opposite side cylinder retract, and the lead screw module works to move the accounting document above the extension plate. Then, one side cylinder and the opposite side cylinder extend to make the accounting document fit against the extension plate. Then, one side suction nozzle and the opposite side suction nozzle stop picking up the document.

[0020] Step 2: The recognition camera identifies the accounting document attached to the extension plate. The centering cylinders on both sides extend, and the moving strips on both sides move closer to the accounting document, centering it. Then, the centering cylinders on both sides retract, and the moving strips on both sides move away from the accounting document.

[0021] Step 3: The opposite air extension causes the opposite suction nozzle to pick up the accounting documents. Then the screw module works, driving the accounting documents to extend between the two conveyor belts. After that, the opposite suction nozzle stops picking up the documents.

[0022] Step 4: The conveyor motor is working, and the rotating rod connected to the conveyor motor rotates. The conveyor belts rotate under the support of the two rotating rods. The upper and lower conveyor belts rotate relative to each other, pressing the accounting documents between the two conveyor belts for flattening and conveying.

[0023] Step 5: When the accounting document is placed on the extension plate, if the recognition camera detects that the accounting document on the side attached to the extension plate has content, the flip motor will work when the accounting document is flattened and conveyed by the two conveyor belts. The flip motor drive end drives the gear to rotate, causing the upper and lower conveyor belts to exchange positions. When the accounting document is conveyed to one end of the conveyor belt, the conveyor motor stops working, the upper spacing adjustment cylinder retracts, causing the upper conveyor belt to leave the accounting document, and then the moving cylinder extends, causing the scanning camera to move above the accounting document. The scanning camera captures the image of the accounting document, the image data processing module processes the captured image, the data conversion module converts the processed image data into a format suitable for storage or transmission, and the data storage module is responsible for saving the scanned data.

[0024] Step 6: If the recognition camera detects that the accounting document attached to the extension board has no content, the flip motor will not work.

[0025] Step 7: When the rotating ring rotates, the avoidance cylinder extends to move one end of the discharge sleeve away from the conveyor belt. When the rotating ring reaches the target position, the avoidance cylinder retracts to its original position and the discharge sleeve returns to its original position. After scanning is completed, the upper spacing adjustment cylinder extends until the conveyor belt is in contact with the accounting document. Then the conveyor motor works to transport the accounting document to the conveyor in the discharge sleeve. The conveyor works to move the accounting document out of the discharge sleeve.

[0026] Step 8: The sealing cylinder on the storage box extends, the sealing cover leaves the storage box, and the accounting documents fall into the storage box. Then the sealing cylinder retracts to seal the storage box and store the accounting documents.

[0027] The accounting document processing system and method made using the technical solution of the present invention have the following characteristics:

[0028] Beneficial effects:

[0029] 1. A large number of unorganized accounting documents are placed in the picking-up section. The picking-up section picks up one accounting document at a time and puts it into the inlet section. The inlet section has the function of identifying the orientation of the accounting document content. When the accounting document with content on the side attached to the extension plate has content, the accounting document is flattened by the two conveyor belts. During the conveying process, the flipping motor works to exchange the positions of the upper and lower conveyor belts, that is, the accounting document is flipped so that the content side is facing up, which is convenient for the scanning unit to scan the accounting document. If the recognition camera identifies that the accounting document with content on the side attached to the extension plate has no content, the flipping motor does not work, realizing the automatic flipping of the accounting document. Therefore, before scanning, the operator does not need to sort the documents in advance so that the content side of the document is facing up, reducing the workload of the operator.

[0030] 2. The scanning process and storage of accounting documents are both conducted in a closed loop. This ensures the security of the accounting documents and prevents the exposure of document information, guaranteeing the safe and normal scanning and use of accounting documents.

[0042] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0043] Example: An accounting document processing system includes a base 1 and a cover 2. A processing structure is mounted on the base 1, and the cover 2 is mounted on the processing structure.

[0044] It should be noted that the processing structure, in conjunction with the cover 2, enables closed scanning and closed classification of accounting documents, ensuring the security and confidentiality of accounting documents.

[0045] In the specific implementation process, the processing structure can preferably be a support base 3, which is installed on the base 1. A fixed ring frame 4 is installed on the support base 3. The fixed ring frame 4 is provided with a protrusion 5. Two retaining rings 6 are symmetrically provided at the opening of the fixed ring frame 4. A rotating ring 7 is movably installed on the fixed ring frame 4. Several meshing teeth 8 are arranged in a circular array on the rotating ring 7. Two annular notches are symmetrically opened on the rotating ring 7. The two annular notches match the two retaining rings 6. A flipping power unit is installed on the protrusion 5. Two spacing adjustment cylinders 9 are symmetrically installed on the inner side wall of the rotating ring 7. A transmission unit is installed at the extension end of the two spacing adjustment cylinders 9. A scanning unit is installed on the base 1. A enclosure 10 is installed on the base 1. A picking unit is installed on the side wall of the enclosure 10. An inlet is installed on the side wall of the enclosure 10 at one end of the transmission unit. A picking unit is installed on the side wall of the enclosure 10 at one end of the inlet unit. An outlet is installed on the side wall of the enclosure 10 at the other end of the transmission unit. A storage unit is installed on the base 1.

[0046] It should be noted that the fixed frame 4 is mounted on the base 1 via the support seat 3. By flipping the power unit, the rotating ring 7 can be concentrically rotated on the fixed frame 4 by the limiting of the two retaining rings 6, so that the upper and lower transmission parts exchange positions. The upper and lower transmission parts are brought closer to each other by adjusting the cylinder so that they can clamp the accounting documents. The picking part is used to place the accounting documents and to send the accounting documents into the upper and lower transmission parts in the enclosure 10 through the inlet part. The transmission parts work to transport the accounting documents and flatten them during the process. The scanning part scans the accounting documents. After scanning, the documents enter the storage part from the outlet part for storage.

[0047] In the specific implementation process, the flipping power unit can preferably be a flipping motor 11. The flipping motor 11 is installed on the side wall of the protrusion 5, and the drive end of the flipping motor 11 moves through the protrusion 5. A gear 12 is fitted on the drive end of the flipping motor 11, and the gear 12 meshes with a number of meshing teeth 8.

[0048] It should be noted that when the flip motor 11 is working, the drive end of the flip motor 11 drives the gear 12 to rotate. Under the meshing of the gear 12 and the meshing teeth 8, the rotating ring 7 rotates concentrically on the fixed ring frame 4 through the limiting of the two retaining rings 6.

[0049] In the specific implementation process, the transmission unit can preferably be a U-shaped seat 13. The U-shaped seat 13 is installed on the telescopic end of the spacing adjustment cylinder 9. Two rotating rods 14 are movably inserted on the U-shaped seat 13. A conveyor belt 15 is fitted on the two rotating rods 14. A conveyor motor 16 is installed on one of the two rotating rods 14.

[0050] It should be noted that when the conveyor motor 16 is working, the rotating rod 14 connected to the conveyor motor 16 rotates, and the conveyor belt 15 rotates under the support of the two rotating rods 14.

[0051] In the specific implementation process, as a preferred and further option, two telescopic rods 17 are installed between the rotating ring 7 and the U-shaped seat 13 to stabilize the U-shaped seat 13;

[0052] In the specific implementation process, the input part can preferably be an input slot 18, which is inserted into the enclosure 10. The input slot 18 is located at the center of the fixed frame 4. Two mounting slots are symmetrically opened on the enclosure 10. A centering cylinder 19 is installed on each of the two mounting slots. The telescopic end of the centering cylinder 19 is movably inserted into the input slot 18. A moving strip 20 is installed on the telescopic end of the centering cylinder 19. The moving strip 20 matches the inner wall of the input slot 18. An extension plate 21 is provided at one end of the input slot 18. A recognition camera 22 is embedded in the center of the upper wall of the extension plate 21.

[0053] It should be noted that the picking-up section places the accounting documents on the extension plate 21, the centering cylinders 19 on both sides extend, and the moving strips 20 on both sides move closer to the accounting documents, so that the accounting documents are centered and aligned with the center of the upper and lower conveyor belts 15, ensuring that the accounting documents are transported in a straight line.

[0054] In the specific implementation process, the part-retrieving part can preferably be a support rod 23. The support rod 23 is installed on the side wall of the enclosure 10. A screw module 24 is installed on the support rod 23. A connecting frame 25 is installed on the moving end of the screw module 24. A fixing plate 26 is installed on one end of the connecting frame 25. Two side cylinders 27 are installed on the lower wall of the fixing plate 26 and on the side close to the enclosure 10. A side suction nozzle 28 is installed on the telescopic end of each of the two side cylinders 27. Two opposite side cylinders 29 are installed on the lower wall of the fixing plate 26 and on the side away from the enclosure 10. Opposite side suction nozzles 30 are installed on the telescopic end of each of the two opposite side cylinders 29. A part-holding box is installed on the side wall of the enclosure 10.

[0055] It should be noted that the storage box is used to hold stacks of accounting documents. One side cylinder 27 and the opposite side cylinder 29 extend, and one side suction nozzle 28 and the opposite side suction nozzle 30 are connected to a power device, such as a vacuum pump. One side suction nozzle 28 and the opposite side suction nozzle 30 pick up an accounting document, and then one side cylinder 27 and the opposite side cylinder 29 retract. The lead screw module 24 works to move the accounting document onto the extension plate 21.

[0056] In the specific implementation process, the scanning unit can preferably be mounted on a mounting frame 31, which is mounted on a base 1. A moving cylinder 32 is mounted on the side wall, and a scanning camera 33 is mounted on the telescopic end of the moving cylinder 32. An image processing component is connected to the scanning camera 33.

[0057] It should be noted that when the upper and lower conveyor belts 15 transport the accounting documents to one end of the conveyor belt 15, the upper spacing adjustment cylinder 9 extends, causing the upper conveyor belt 15 to leave the accounting documents. Then, the moving cylinder 32 extends, causing the scanning camera 33 to move above the accounting documents to scan them.

[0058] In the specific implementation process, the image processing component can preferably be an image data processing module 34, which is connected to the scanning camera 33. A data conversion module 35 is connected to the image data processing module 34, and a data storage module 36 is connected to the data conversion module 35.

[0059] It should be noted that the scanning camera 33 captures images of accounting documents, the image data processing module 34 processes the captured images, the data conversion module 35 converts the processed image data into a format suitable for storage or transmission, and the data storage module 36 is responsible for saving the scanned data.

[0060] In the specific implementation process, the outlet can preferably be through a hole, which is opened on the side wall of the enclosure 10. An avoidance cylinder 37 is installed on the side wall of the enclosure 10. A connecting plate 38 is installed on the telescopic end of the avoidance cylinder 37. A discharge slot sleeve 39 is installed on the connecting plate 38. The discharge slot sleeve 39 is movably inserted into the through hole. One end of the discharge slot sleeve 39 has an inclined surface 40. An avoidance groove is opened on the bottom inner side of the discharge slot sleeve 39. A conveyor 41 is installed on the avoidance groove. The upper wall of the conveyor 41 and the bottom inner side of the discharge slot sleeve 39 are on the same plane.

[0061] It should be noted that when the rotating ring 7 rotates, the avoidance cylinder 37 extends, causing one end of the discharge sleeve 39 to move away from the conveyor belt 15. When the rotating ring 7 rotates to the target position, the avoidance cylinder 37 retracts to its original position, the discharge sleeve 39 returns to its original position, and the conveyor belt 15 works to send the accounting documents into the conveyor 41 in the discharge sleeve 39. The conveyor 41 works to move the accounting documents out of the discharge sleeve 39. The inclined surface 40 facilitates the entry of the accounting documents into the discharge sleeve 39.

[0062] In the specific implementation process, the storage unit can preferably use an electric turntable 42, which is installed on the base 1. A lifting cylinder 43 is installed on the electric turntable 42, and a placement panel 44 is installed on the extension end of the lifting cylinder 43. Several storage components are installed on the placement panel 44, and the several storage components are installed in a circular array on the placement panel 44.

[0063] It should be noted that by operating the lifting cylinder 43, several storage components are brought close to the discharge slot sleeve 39, and the electric turntable 42 rotates, causing the several storage components to rotate.

[0064] In the specific implementation process, several storage components can preferably have two clamping cylinders 45, the two clamping cylinders 45 are symmetrically installed on the placement panel 44, and clamping plates 46 are installed on the telescopic ends of the two clamping cylinders 45. A storage box 47 is movably placed on the placement panel 44, and the clamping plates 46 are movably attached to the storage box 47. A sealing cylinder 48 is installed on the side wall of the storage box 47, and a sealing cover 49 is installed on the sealing cylinder 48.

[0065] It should be noted that the two clamping cylinders 45 clamp the storage box 47 through the clamping plate 46 to fix the storage box 47. This can fix storage boxes 47 of different sizes, and has a wide range of applications. When the accounting documents move into the discharge slot 39, the sealing cylinder 48 on the storage box 47 extends, and the sealing cover 49 leaves the storage box 47. The sealing cover 49 is higher than the upper wall of the discharge slot 39, and the accounting documents fall into the storage box 47. Then the sealing cylinder 48 retracts to seal the storage box 47, which ensures the safety of the accounting documents and prevents the exposure of the document information. When one storage box 47 is full, the electric turntable 42 rotates to the next storage box 47 to be aligned with the bottom of the discharge slot 39 for the storage of accounting documents.

[0066] Working principle: A large number of accounting documents are placed horizontally in the storage box, eliminating the need to arrange the documents so that the content side is facing up, reducing the workload of the staff. One side cylinder 27 and the opposite side cylinder 29 extend, and one side suction nozzle 28 and the opposite side suction nozzle 30 pick up one accounting document. Then, one side cylinder 27 and the opposite side cylinder 29 retract, and the lead screw module 24 operates to move the accounting document above the extension plate 21. Then, one side cylinder 27 and the opposite side cylinder 29 extend to make the accounting document adhere to the extension plate 21. Then, one side suction nozzle 28 and the opposite side suction nozzle 30 stop picking up the document. At this time, the recognition camera 22 recognizes the accounting document on the side that is adhered to the extension plate 21. At the same time, the accounting document is placed on the extension plate 21, and the centering cylinders 19 on both sides extend, and the moving cylinders on both sides... The moving strip 20 approaches the accounting document, centering it. Then, the centering cylinders 19 on both sides retract, causing the moving strip 20 to move away from the accounting document. The opposite side extends, causing the opposite suction nozzle 30 to pick up the accounting document. Then, the lead screw module 24 operates, driving the accounting document between the two conveyor belts 15. The opposite suction nozzle 30 then stops picking up the document. The conveyor motor 16 then operates, and the rotating rod 14 connected to the conveyor motor 16 rotates. The conveyor belts 15 rotate under the support of the two rotating rods 14. The upper and lower conveyor belts 15 rotate relative to each other, pressing the accounting document between the two conveyor belts 15 for flattening and conveying. When the accounting document is placed on the extension plate 21, if the recognition camera 22 recognizes that the accounting document on the side attached to the extension plate 21 has content, then the accounting document... When the document is flattened and conveyed by the two conveyor belts 15, the flip motor 11 operates. The drive end of the flip motor 11 drives the gear 12 to rotate. Under the meshing of the gear 12 and the meshing teeth 8, the rotating ring 7 rotates concentrically on the fixed ring frame 4 through the limitation of the two retaining rings 6, causing the upper and lower conveyor belts 15 to exchange positions. At this time, the content side of the accounting document is facing up. When the accounting document is conveyed to one end of the conveyor belt 15, the conveyor motor 16 stops working, and the upper spacing adjustment cylinder 9 retracts, causing the upper conveyor belt 15 to leave the accounting document. Then, the moving cylinder 32 extends, causing the scanning camera 33 to move above the accounting document. The scanning camera 33 captures the image of the accounting document, and the image data processing module 34 processes the captured image. The conversion module 35 converts the processed image data into a format suitable for storage or transmission. The data storage module 36 is responsible for saving the scanned data. If the recognition camera 22 identifies that the accounting document attached to the extension plate 21 has no content, the flip motor 11 does not work. When the rotating ring 7 rotates, the avoidance cylinder 37 extends, causing one end of the discharge sleeve 39 to move away from the conveyor belt 15. When the rotating ring 7 rotates to the target position, the avoidance cylinder 37 retracts to its original position, and the discharge sleeve 39 returns to its original position. After scanning is completed, the upper spacing adjustment cylinder 9 extends to the conveyor belt 15 to attach to the accounting document. Then, the conveyor motor 16 works, conveying the accounting document to the conveyor 41 in the discharge sleeve 39. The conveyor 41 works to remove the accounting document from the discharge sleeve 39.Two clamping cylinders 45 clamp the storage box 47 via clamping plates 46, securing the storage box 47. This system can hold storage boxes 47 of different sizes, making it widely applicable. When accounting documents move into the discharge slot 39, the sealing cylinder 48 on the storage box 47 extends, and the sealing cover 49 leaves the storage box 47, with the cover 49 higher than the upper wall of the discharge slot 39. The accounting documents fall into the storage box 47. Subsequently, the sealing cylinder 48 retracts, sealing the storage box 47. This ensures the security of the accounting documents and prevents the exposure of document information. When one storage box 47 is full, the electric turntable 42 rotates to the next storage box 47, aligning it with the bottom of the discharge slot 39 for storing the accounting documents.

[0067] In summary:

[0068] 1. A large number of unorganized accounting documents are placed in the collection section. The collection section picks up one accounting document at a time and puts it into the import section. The import section has the function of identifying the orientation of the accounting document content. When the accounting document attached to the extension plate 21 has content, the accounting document is flattened and conveyed by the two conveyor belts 15. The flipping motor works to exchange the positions of the upper and lower conveyor belts 15, that is, the accounting document is flipped so that the content side is facing up, which is convenient for the scanning section to scan the accounting document. If the recognition camera 22 recognizes that the accounting document attached to the extension plate 21 has no content, the flipping motor 11 does not work, realizing the automatic flipping of the accounting document. Therefore, before scanning, the operator does not need to sort the documents in advance so that the content side of the document is facing up, which reduces the workload of the operator.

[0069] 2. The scanning process and storage of accounting documents are both conducted in a closed system. This ensures the security of accounting documents and prevents the exposure of document information, thus guaranteeing the safe and normal scanning and use of accounting documents.

[0070] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.

10. A method for processing accounting documents, characterized in that, The following steps are included: Step 1: Place a large number of accounting documents horizontally in the storage box. Extend one side cylinder (27) and the opposite side cylinder (29). One side suction nozzle (28) and the opposite side suction nozzle (30) pick up one accounting document. Then, one side cylinder (27) and the opposite side cylinder (29) retract. The lead screw module (24) works to move the accounting document above the extension plate (21). Then, one side cylinder (27) and the opposite side cylinder (29) extend to make the accounting document fit against the extension plate (21). Then, one side suction nozzle (28) and the opposite side suction nozzle (30) stop picking up the document. Step 2: The recognition camera (22) recognizes the accounting document on the side attached to the extension plate (21). The centering cylinders (19) on both sides extend, and the moving strips (20) on both sides move closer to the accounting document to center it. Then, the centering cylinders (19) on both sides retract, and the moving strips (20) on both sides move away from the accounting document. Step 3: The opposite side air extends, causing the opposite side suction nozzle (30) to pick up the accounting documents. Then the screw module (24) works, driving the accounting documents to extend between the two conveyor belts (15). Then the opposite side suction nozzle (30) stops picking up the documents. Step 4: The conveyor motor (16) is working, and the rotating rod (14) connected to the conveyor motor (16) rotates. The conveyor belt (15) rotates under the support of the two rotating rods (14). The upper and lower conveyor belts (15) rotate relative to each other, pressing the accounting documents between the two conveyor belts (15) for flattening and transmission. Step 5: When the accounting document is placed on the extension plate (21), if the recognition camera (22) recognizes that the accounting document on the side attached to the extension plate (21) has content, the accounting document is flattened and conveyed by the two conveyor belts (15). The flip motor (11) works, and the drive end of the flip motor (11) drives the gear (12) to rotate, so that the upper and lower conveyor belts (15) exchange positions. When the accounting document is conveyed to one end of the conveyor belt (15) by the conveyor belt (15), the conveyor motor (16) stops working, the spacing adjustment cylinder (9) located above retracts, so that the upper conveyor belt (15) leaves the accounting document. Then the moving cylinder (32) extends, so that the scanning camera (33) moves to the top of the accounting document. The scanning camera (33) collects the image of the accounting document. The image data processing module (34) processes the collected image. The data conversion module (35) converts the processed image data into a format suitable for storage or transmission. The data storage module (36) is responsible for saving the scanned data. Step 6: If the recognition camera (22) recognizes that the accounting document attached to the side of the extension plate (21) has no content, the flip motor (11) will not work. Step 7: When the rotating ring (7) rotates, the avoidance cylinder (37) extends, so that one end of the discharge sleeve (39) moves away from the conveyor belt (15). When the rotating ring (7) rotates to the target position, the avoidance cylinder (37) retracts to its original position, and the discharge sleeve (39) returns to its original position. After the scanning is completed, the upper spacing adjustment cylinder (9) extends to the conveyor belt (15) to fit the accounting document. Then the conveyor motor (16) works to transport the accounting document to the conveyor (41) in the discharge sleeve (39). The conveyor (41) works to move the accounting document out of the discharge sleeve (39). Step 8: The sealing cylinder (48) on the storage box (47) extends, the sealing cover (49) leaves the storage box (47), and the accounting documents fall into the storage box (47). Then the sealing cylinder (48) retracts to seal the storage box (47) and store the accounting documents.
