Description

Technical Field

[0001] This invention belongs to the field of archives management technology, and relates to an archives management AGV robot, particularly a positioning structure for an archives management AGV robot. Background Technology

[0002] With the continuous progress of society, the number of archival documents accumulated in archives has increased dramatically. Currently, the sorting of these documents mainly relies on the collaborative work of manual labor and archival management software systems. However, in this model, manual sorting is inefficient, costly, and prone to fatigue under long hours of intense labor, leading to a high error rate. To alleviate this dilemma, a series of robots specifically designed for archival sorting tasks have gradually emerged in the market, aiming to reduce the burden of manual labor and improve overall work efficiency.

[0003] The AGV robot for document management seamlessly integrates with unmanned warehouses. It receives document information from the business system, automatically coordinates the opening and closing of corresponding filing cabinets, and autonomously moves to the corresponding documents. Through visual recognition of document features, it calculates high-precision document location information and controls the robotic arm to move to the document, realizing document loading and unloading operations. It has the functions of one-click operation for storage and retrieval, one-key operation for designated areas, and intelligent task planning. It enables unmanned and intensive management of physical documents, achieves separation of personnel and documents, and effectively solves the security and authenticity issues that exist in the manual management of confidential documents.

[0004] A search revealed a positioning structure for an AGV robot used for document management [Application No.: CN202321422049.7; Publication No.: CN221190513U]. This positioning structure includes a bracket mounted on the AGV robot and a base plate of a file shelf mounted on a filing cabinet. This invention uses a visual recognition mark to locate the file box to be managed by the AGV robot, adjusting its horizontal and vertical positions. The AGV robot's telescopic arm pushes the bracket close to the base plate of the file shelf. The bracket is positioned horizontally by a first positioning block engaging with left and right positioning slots, and vertically by a second positioning block engaging with a height positioning slot. After alignment, the AGV robot stores or retrieves the file box, improving the alignment accuracy of the document management AGV robot.

[0005] Although the positioning structure of the file management AGV robot disclosed in this patent can improve the alignment accuracy of the file management AGV robot by using the second positioning block and the height positioning slot for height positioning, the docking of a single positioning block and positioning slot makes it inconvenient for the AGV robot to find and locate files during file management. It cannot accurately dock and retrieve files. Moreover, after positioning, the AGV robot needs to enter the inside of the file shelf with a clamp to clamp and retrieve the file box, which requires a lot of space around the file and seriously affects the efficiency and quality of file retrieval. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a positioning structure for an AGV robot for document management. The technical problem this invention aims to solve is: how to locate and precisely dock documents during retrieval, and facilitate stable retrieval and placement of documents.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A positioning structure for an AGV robot for file management includes a file rack, a movable frame disposed outside the file rack, and a recognition camera fixedly installed on the top of the movable frame. A lead screw is rotatably connected inside the movable frame and is driven by a drive motor. A movable block is connected to the outer wall of the lead screw via a ball nut. An insert plate is fixedly connected to the bottom outer wall of the movable block. A suction unit is connected to the top of the movable block and is located inside the movable frame. The insert plate is telescopically disposed at the bottom of the movable frame, and a limit block is fixedly connected to the outer wall of the insert plate.

[0009] The bottom outer wall of the mobile frame is fixedly connected to a mounting plate, and a gear disk is rotatably connected inside the mounting plate, and the gear disk is driven by an electric motor.

[0010] The outer wall of the gear disk is movably connected to a rack, and the rack is fixedly installed on the bottom outer wall of the file rack. The file rack has multiple file slots equidistantly arranged inside, and each file slot is equipped with a pusher unit.

[0011] The pushing unit includes a baffle, which is telescopically disposed inside the file slot. A first return spring is fixedly connected to the bottom end of the baffle, and the first return spring is fitted into the bottom of the baffle. A limit ball is fixedly connected to the bottom end of the first return spring.

[0012] The file slot has a corresponding limiting hole inside the limiting ball, and a transmission bar is slidably connected to the bottom of the limiting hole, which is connected to the limiting block.

[0013] The working principle of this invention is as follows: The document management AGV robot moves between document racks via a connected mobile frame. A recognition camera at the top of the mobile frame identifies the documents inside the racks, facilitating document retrieval. To assist in the positioning of the recognition camera, a mounting plate is fixedly connected to the outer wall of the mobile frame. A gear disk is rotated inside the mounting plate, allowing the mobile frame to move by rotating on the outer wall of the rack. This allows the user to precisely move the mobile frame at the front end of the document rack using the rotation position of the electric motor. This design, compared to existing direct positioning methods using recognition cameras, provides a more efficient and efficient system. Position search enables mechanical positioning of the file slot, ensuring the accuracy and stability of file management. After the moving frame moves to the designated position at the front of the file rack, the drive motor is energized, causing the lead screw to rotate. This, in turn, drives the movable block to move outward from inside the moving frame. By connecting a moving plate to the top of the movable block, the moving plate moves to the front of the moving frame, facilitating the retrieval of files from inside the file rack. Simultaneously, by installing an insert plate at the bottom of the movable block, the insert plate moves outward synchronously. Through the insertion hole and through hole, the insert plate is inserted into the bottom of the transmission bar. A limiting connection is fixed to the outer wall of the insert plate. The block, under the limiting action of the through hole, prevents the limiting block from passing through the through hole. Therefore, when the insert plate is inserted into the transmission bar, the insert plate can drive the transmission bar to move synchronously through the limiting block fixed to the outer wall. This causes the transmission bar to move towards the limiting hole. Furthermore, the wedge-shaped action at one end of the transmission bar causes it to press against the limiting ball at the bottom, preventing the limiting ball from limiting the limiting hole. After the baffle is no longer limited, it resets under the elastic action of the telescopic spring, pushing the file box out of the file slot at the rear end. This facilitates the movement of the frame at the front end through the moving plate. The suction cups on the surface precisely adsorb the files, enabling efficient retrieval after precise positioning and docking. After retrieval, the screw rotates in the opposite direction, moving the moving plate and insert plate into the moving frame. This allows the transmission bar to move without being limited by the limit block, and the transmission bar is reset under the elastic action of the second return spring. Simultaneously, after the file is retrieved from the file slot, the baffle resets inside the file slot. This allows the file to be placed inside the file slot and then compressed by the telescopic spring. This causes the baffle to move the limit ball to the limit hole position for automatic limiting, ensuring the stability of the baffle inside the file slot.

[0014] The material suction unit includes a movable plate, a guide block is fixedly connected to the outer wall of the movable plate, and a guide groove is slidably connected to the outer wall of the guide block, and the guide groove is opened on the inner wall of the movable frame.

[0015] Multiple suction cups are fixedly connected to the surface of the movable plate.

[0016] With the above structure, the lead screw can drive the moving plate to move stably through the movable block, making it easy for the moving plate to extend inside the moving frame to retrieve the files inside the file rack. Moreover, by setting multiple suction cups on the surface of the moving plate, multiple suction cups can simultaneously adsorb and grasp one side of the file box. Compared with the existing clamps, this effectively saves the working area and improves the stability and safety of the file retrieval process.

[0017] The surface of the movable frame is provided with through holes that can accommodate the movement of the insert plate and the limiting block;

[0018] The file rack has a through hole on one side for accommodating insert plates, and the insert hole corresponds to the through hole.

[0019] With the above structure, the through holes and insertion holes allow the insert plate to extend out from inside the movable frame and insert into the bottom of the file rack, facilitating precise docking between the movable frame and the file rack. Furthermore, by fixing a limiting block to the outer wall of the insert plate, the limiting operation of the insert plate on the transmission bar is realized, which facilitates the transmission effect of the transmission bar.

[0020] A telescopic spring is fixedly connected to the rear end face of the baffle, and a file rack is fixedly connected to the other end of the telescopic spring.

[0021] The bottom of the file rack is provided with a movable groove that can accommodate the sliding of the baffle, and the movable groove is opened on the inner bottom wall of the file rack.

[0022] With the above structure and the addition of a telescopic spring, the baffle surface can be reset when there are no files, facilitating efficient and accurate identification of the file slot by the recognition camera. Furthermore, the movable groove at the bottom of the file rack ensures the accuracy of the baffle's movement, and the structure is compact and highly stable.

[0023] The end of the transmission bar near the limiting hole is wedge-shaped, and the end of the transmission bar away from the limiting hole is fixedly connected to a second return spring. The other end of the second return spring is fixedly installed with a fixing plate, and the fixing plate is fixedly connected inside the file rack.

[0024] Using the above structure, the wedge-shaped structure of the transmission bar allows it to move under the action of the limiting block via the insert plate. This stretches the second return spring, causing the transmission bar to press against the limiting ball at the bottom through the wedge-shaped structure at one end. This prevents the limiting ball from limiting the limiting hole, allowing the baffle to return to its original position under the extension spring. The baffle then pushes the file box out of the file slot at the rear end, facilitating precise suction of the file box by the suction cup at the front of the moving frame. This improves the accuracy of file docking, and also provides good transmission performance and strong practicality.

[0025] The bottom of the transmission bar has a through hole that can accommodate the insertion of the insert plate, and the through hole fits and limits the positioning block on one side.

[0026] With the above structure, the limiting block cannot pass through the through hole. When the insert plate is inserted into the transmission bar, the insert plate can drive the transmission bar to move synchronously through the limiting block fixedly connected to the outer wall. This causes the transmission bar to squeeze the limiting ball at the bottom through the wedge at one end.

[0027] A slider is fixedly connected to the top of the transmission bar, and the slider is slidably connected to the inner wall of the file rack.

[0028] With the above structure, the transmission bar moves precisely through the insertion plate under the action of the slider, ensuring that the transmission bar accurately squeezes the limit ball at the bottom and improving the movement effect of the transmission bar.

[0029] The output end of the drive motor is fixedly connected to a lead screw, and the drive motor is fixedly installed on the outer wall of the mobile frame.

[0030] The output end of the electric motor is fixedly mounted with a gear disk, and the electric motor is fixedly mounted on the surface of the mounting plate.

[0031] By adopting the above structure and setting the drive motor, the lead screw is stably driven, which facilitates the precise movement of the movable block inside the moving frame. This enables the moving plate to extend and retract within the moving frame, facilitating the suction and retrieval of the file box after the moving frame is positioned. Furthermore, by setting an electric motor on the surface of the mounting plate, the gear plate rotates stably, allowing the electric motor to drive the gear plate to precisely align with the front end of the corresponding file slot. Compared to existing methods that rely on direct positioning and locating via recognition cameras, this method achieves mechanical positioning of the file slot, ensuring the accuracy and stability of file management.

[0032] Each suction cup has an internal ventilation hole, and the moving plate has an internal ventilation groove that communicates with the ventilation hole. The side wall of the ventilation groove is connected to a transmission opening and closing assembly.

[0033] The above structure, with its ventilation holes, facilitates the evacuation of air from the inside of the suction cups, which helps to achieve a stable adsorption effect. Furthermore, the ventilation slots allow the air compressor and the moving plate to be connected simultaneously to vacuum multiple suction cups, facilitating simultaneous air extraction and intake from multiple ventilation holes. This results in high stability, good synchronization, and ensures the adsorption effect of the files on one side of multiple suction cups.

[0034] The transmission opening and closing assembly includes a sealing plate, which is movably fitted to the inner wall of the ventilation groove. A blocking block is fixedly installed on the outer wall of the sealing plate and is movably inserted into the interior of the movable plate. A support spring is sleeved on the outer wall of the blocking block, and a stop block is fixedly installed on the surface of the blocking block.

[0035] The surface of the abutment block is movably fitted with a fixed column, and the fixed column is fixedly installed on the inner wall of the movable plate.

[0036] With the above structure, when the moving plate moves into the moving frame, the fixed column fits against the abutment block, which causes the blocking block to drive the sealing plate to open the ventilation groove, allowing air to enter the ventilation groove. This allows air to enter the suction cup after the moving plate moves into the moving frame, releasing the file.

[0037] Compared with the prior art, the positioning structure of the file management AGV robot of the present invention has the following advantages:

[0038] 1. In this invention, through the meshing connection between the movable frame and the file rack, the user can drive the gear to rotate precisely by the electric motor under the action of the rack and pinion. This allows the user to locate and search for files by precisely moving the gear on the surface of the rack. Compared with the existing single recognition camera positioning, this method is more stable and accurate. It also achieves precise docking with the file rack and has a compact structure.

[0039] 2. In this invention, with the bottom of the movable block fixedly connected to the insert plate, and the outer wall of the insert plate fixedly connected to the limiting block, the insert plate can move synchronously with the transmission bar when it is moving, through the limiting block. Furthermore, the wedge-shaped action of the transmission bar causes it to move under the action of the limiting block, driven by the insert plate. This stretches the second return spring, causing the transmission bar to press the limiting ball at the bottom through the wedge structure at one end. This prevents the limiting ball from limiting the limiting hole, allowing the baffle to return to its original position under the tension spring. The baffle then pushes the file box out of the file slot at the rear end, facilitating precise suction of the file box by the suction cup at the front end of the movable frame. This improves the accuracy of file docking, provides good transmission performance, and is highly practical.

[0040] 3. In this invention, by fixing a telescopic spring to the rear end face of the baffle, the baffle is closed inside the file slot when no files are placed inside, making it easy for users to have a clear understanding of the storage of the file rack. Moreover, by connecting a limiting ball to the bottom of the baffle through a first reset spring, when the baffle is squeezed by files, the limiting ball moves to the position of the limiting hole and automatically limits the baffle, ensuring the stability of the files inside the file slot. The structure is compact and easy to promote and use.

[0041] 4. In this invention, by setting a transmission opening and closing component inside the moving plate, when the moving plate moves into the moving frame, the fixed column fits against the abutment block, causing the blocking block to drive the sealing plate to open the ventilation groove, thereby allowing air to enter the ventilation groove. This allows air to enter the suction cup after the moving plate moves into the moving frame to loosen the file, ensuring the safety and stability of the file inside the moving frame after it is retrieved. This achieves automatic unloading after the moving plate moves the file into the moving frame, and the structure is simple with good transmission effect. Attached Figure Description

[0051] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0052] like Figures 1-8 As shown, a positioning structure for an AGV robot for file management includes a file rack 16, a movable frame 1 disposed outside the file rack 16, and an identification camera 2 fixedly mounted on the top of the movable frame 1, a lead screw 3, a drive motor 4, a movable block 5, a movable plate 6, a suction cup 7, a guide block 8, a guide groove 9, an insert plate 10, a limit block 11, a through hole 12, a mounting plate 13, a gear disk 14, an electric motor 15, a rack 17, an insertion hole 18, a telescopic spring 19, a baffle 20, a first return spring 21, a limit ball 22, a limit hole 23, a transmission bar 24, a second return spring 25, a fixed plate 26, and a slider. 27. The moving groove 28 and slide rail 29 are rotatably connected to a lead screw 3 inside the moving frame 1, and the lead screw 3 is driven by a drive motor 4. Specifically, the output end of the drive motor 4 is fixedly connected to the lead screw 3, and the drive motor 4 is fixedly installed on the outer wall of the moving frame 1, realizing the stable drive of the lead screw 3 by the drive motor 4. At the same time, a movable block 5 is connected to the outer wall of the lead screw 3 by a ball nut, which facilitates the drive motor 4 to drive the movable block 5 to move stably through the lead screw 3. Moreover, the movable block 5 is slidably connected to the inner wall of the moving frame 1, ensuring the accuracy of the movement of the movable block 5. At the same time, the top of the movable block 5 is connected to... The system is equipped with a suction unit located inside the movable frame 1. The suction unit includes a movable plate 6, which is driven by the movable block 5 to move precisely within the movable frame 1. A guide block 8 is fixedly connected to the outer wall of the movable plate 6, and a guide groove 9 is slidably connected to the outer wall of the guide block 8. The guide groove 9 is located on the inner wall of the movable frame 1, achieving precise guidance of the movable plate 6. The system is simple in structure and highly stable. Furthermore, to ensure stable retrieval of the file box after the movable plate 6 extends out from inside the movable frame 1, multiple suction cups 7 are fixedly connected to the surface of the movable plate 6, facilitating the movement of multiple suction cups. The disk 7 simultaneously adsorbs and grips one side of the file box. Compared with the existing clamps, it effectively saves the working area and improves the stability and safety of the file retrieval process. At the same time, an insert plate 10 is fixedly connected to the bottom outer wall of the movable block 5. When the movable block 5 moves with the extension and retraction of the moving plate 6, the insert plate 10 moves synchronously at the bottom of the moving frame 1. A limit block 11 is fixedly connected to the outer wall of the insert plate 10. In order to achieve stable extension and movement of the insert plate 10 inside the moving frame 1, a through hole 12 is provided on the surface of the moving frame 1 to accommodate the movement of the insert plate 10 and the limit block 11.

[0053] Considering the accuracy of the mobile shelf 1 in positioning and retrieving files on one side of the file rack 16, a mounting plate 13 is fixedly connected to the bottom outer wall of the mobile shelf 1, and a gear disk 14 is rotatably connected inside the mounting plate 13. The gear disk 14 is driven by an electric motor 15. Specifically, the output end of the electric motor 15 is fixedly mounted on the gear disk 14, and the electric motor 15 is fixedly mounted on the surface of the mounting plate 13. With this setting, the electric motor 15 can drive the gear disk 14 to move, achieving a stable driving effect on the gear disk 14.

[0054] To achieve stable docking of the gear disk 14, a rack 17 is movably meshed with the outer wall of the gear disk 14, and the rack 17 is fixedly installed on the bottom outer wall of the file rack 16. Meanwhile, multiple file slots are equidistantly arranged inside the file rack 16, and each file slot is equipped with a pushing unit. This arrangement allows the moving frame 1 to move on the surface of the file rack 16 via an AGV robot as the gear disk 14 rotates on the outer wall of the rack 17. This facilitates precise docking of the gear disk 14 with the corresponding file slot via the electric motor 15. Compared to the existing direct positioning and searching method using the recognition camera 2, this method achieves mechanical positioning of the file slots, ensuring the accuracy and reliability of file management. For stability, in order to enable the retrieval of the file box after positioning at the front end of the file slot, a pushing unit is provided inside the file slot. The pushing unit includes a baffle 20, which is telescopically installed inside the file slot. Specifically, a telescopic spring 19 is fixedly connected to the rear end of the baffle 20, and the other end of the telescopic spring 19 is fixedly connected to the file rack 16, which facilitates the stable telescopic movement of the file rack 16 inside the file slot. In addition, considering the stability of the movement of the file rack 16, a moving groove 28 is provided at the bottom of the file rack 16 to accommodate the sliding of the baffle 20. The moving groove 28 is opened on the inner bottom wall of the file slot, which realizes the stable limiting of the movement of the file rack 16. The structure is simple and has strong stability.

[0055] To ensure the stability of the file box inside the file slot, a first return spring 21 is fixedly connected to the bottom end of the baffle 20. The first return spring 21 is fitted into the bottom of the baffle 20, and a limit ball 22 is fixedly connected to the bottom end of the first return spring 21. Simultaneously, a limit hole 23 is formed inside the file slot corresponding to the limit ball 22. With this arrangement, when the baffle 20 moves the limit ball 22 to the position of the limit hole 23, the limit ball 22, under the elastic action of the first return spring 21, limits the limit hole 23, ensuring stability after the baffle 20 moves into the file slot. Furthermore, to allow for flexible setting of the limit ball 22, a transmission bar 24 is slidably connected to the bottom end of the limit hole 23, and the transmission bar 24 is connected to the limit block 11. Considering the transmission between the transmission bar 24 and the insert plate 10... The file rack 16 has a through hole 18 on one side for inserting the insert plate 10. The through hole 18 corresponds to the through hole 12. This arrangement allows the insert plate 10 to extend out of the movable frame 1 and be inserted into the bottom of the file rack 16, facilitating precise docking between the movable frame 1 and the file rack 16. At the same time, the bottom of the transmission bar 24 has a through hole for inserting the insert plate 10. The through hole is fitted and limited by the limiting block 11 on one side. Under the limiting effect of the through hole on the limiting block 11, the limiting block 11 cannot pass through the through hole. Thus, when the insert plate 10 is inserted into the transmission bar 24, the insert plate 10 can drive the transmission bar 24 to move synchronously through the limiting block 11 fixedly connected to the outer wall. This causes the wedge-shaped part of the transmission bar 24 to press the limiting ball 22 at the bottom.

[0056] Furthermore, to achieve the squeezing effect of the transmission bar 24 on the limiting ball 22, the end of the transmission bar 24 near the limiting hole 23 is wedge-shaped, and the end of the transmission bar 24 away from the limiting hole 23 is fixedly connected to a second return spring 25. The other end of the second return spring 25 is fixedly installed with a fixing plate 26, which is fixedly connected to the inside of the file rack 16. A slider 27 is fixedly connected to the top of the transmission bar 24, and the slider 27 is slidably connected to the inner wall of the file rack 16. With this arrangement, the transmission bar 24 is driven by the insert plate 10 under the action of the limiting block 11. When the movement is initiated, the second return spring 25 is stretched, causing the transmission bar 24 to press the limiting ball 22 at the bottom through the wedge structure at one end. This prevents the limiting ball 22 from limiting the limiting hole 23, thus causing the baffle 20 to return to its original position under the tension spring 19. The baffle 20 then pushes the file box out of the file slot at the rear end, facilitating the precise adsorption of the file box by the suction cup 7 at the front end of the moving frame 1. This improves the accuracy of the file docking and achieves precise transmission of the moving frame 1 after docking with the file rack 16. It has high stability, ensures the accuracy and safety of file docking, and is highly practical.

[0057] Furthermore, to ensure the precise adsorption of the suction cups 7 within the moving plate 6, ventilation holes 30 are provided inside each suction cup 7. These ventilation holes 30 facilitate air evacuation from the inside of the suction cups 7, contributing to a stable adsorption effect. Simultaneously, to achieve simultaneous vacuuming of multiple suction cups 7, ventilation grooves 31 communicating with the ventilation holes 30 are provided inside the moving plate 6, facilitating simultaneous air extraction and intake from the multiple ventilation holes 30. Moreover, to ensure stable operation of the suction cups 7 within the moving frame 1, a transmission opening and closing assembly is connected to the side wall of the ventilation groove 31. Specifically, the transmission opening and closing assembly includes a sealing plate 32, which is movably and closely fitted to the inner wall of the ventilation groove 31. This ensures that during vacuuming, the sealing plate 32 effectively seals the interior of the ventilation groove 31, guaranteeing its ventilation effect. Additionally, in a sealed environment... A blocking block 33 is fixedly installed on the outer wall of the sealing plate 32, and the blocking block 33 is movably inserted into the interior of the moving plate 6. A support spring 34 is sleeved on the outer wall of the blocking block 33. Under the elastic action of the support spring 34, the sealing plate 32 closes the venting groove 31 in the normal state, ensuring the sealing effect of the sealing plate 32. At the same time, a stop block 35 is fixedly installed on the surface of the blocking block 33. A fixing post 36 is movably attached to the surface of the stop block 35, and the fixing post 36 is fixedly installed on the inner wall of the moving plate 6. With this arrangement, when the fixing post 36 is attached to the stop block 35, the blocking block 33 drives the sealing plate 32 to open the venting groove 31, thereby allowing air to enter the interior of the venting groove 31. After the moving plate 6 moves into the moving frame 1, air enters the suction cup 7 to release the file, realizing automatic unloading after the moving plate 6 moves the file into the moving frame 1.

[0058] The working principle of this invention is as follows: In use, the document management AGV robot moves between document racks 16 via a connected mobile frame 1. The recognition camera 2 at the top of the mobile frame 1 identifies the documents inside the document racks 16, facilitating document retrieval. To assist in the positioning of the recognition camera 2, a mounting plate 13 is fixedly connected to the outer wall of the mobile frame 1. A gear disk 14 is rotatably connected inside the mounting plate 13, allowing the gear disk 14 to rotate on the outer wall of the rack 17, thus moving the mobile frame 1. This allows the user to precisely move the mobile frame 1 at the front end of the document racks 16 by adjusting the rotation position of the electric motor 15. This setup, compared to existing methods that rely on direct positioning and retrieval via the recognition camera 2, provides a more efficient and efficient system. Mechanical positioning of the file slots is achieved, ensuring the accuracy and stability of file management. After the movable frame 1 moves to the designated position at the front end of the file rack 16, the drive motor 4 is energized, causing the lead screw 3 to rotate. This causes the lead screw 3 to synchronously drive the movable block 5 to move outward inside the movable frame 1. By connecting the movable plate 6 to the top of the movable block 5, the movable plate 6 moves to the front of the movable frame 1, facilitating the movable plate 6 to pick up the files inside the file rack 16. At the same time, by installing the insert plate 10 at the bottom of the movable block 5, the insert plate 10 moves outward synchronously. Under the action of the insertion hole 18 and the through hole 12, the insert plate 10 is inserted into the bottom of the transmission bar 24. By fixing the limiting block 11 to the outer wall of the insert plate 10, the transmission bar 24 is connected to the transmission bar 24. Under the limiting action of the hole on the limiting block 11, the through hole cannot allow the limiting block 11 to pass through the through hole. Therefore, when the insert plate 10 is inserted into the transmission bar 24, the insert plate 10 can drive the transmission bar 24 to move synchronously through the limiting block 11 fixedly connected to the outer wall. This causes the transmission bar 24 to move towards the limiting hole 23. Under the wedge action at one end of the transmission bar 24, the transmission bar 24 squeezes the limiting ball 22 at the bottom through the wedge structure, so that the limiting ball 22 does not limit the limiting hole 23. After the baffle 20 is no longer limited, the baffle 20 is reset under the elastic action of the telescopic spring 19, so that the baffle 20 pushes the file out of the file slot at the rear end, making it convenient for the moving frame 1 to move the file box through the moving plate 6 at the front end. The suction cup 7 precisely adsorbs the file, and by setting a ventilation groove 31 inside the moving plate 6, the sealing plate 32 effectively seals the inside of the ventilation groove 31 when a vacuum is drawn, ensuring the ventilation effect of the ventilation groove 31 and guaranteeing the adsorption stability of the suction cup 7. Under the elastic action of the support spring 34, the sealing plate 32 closes the ventilation groove 31 under normal conditions, ensuring the sealing effect of the sealing plate 32. At the same time, it realizes efficient retrieval of the file after precise positioning and docking. After retrieval, the moving plate 6 and the insert plate 10 are moved by the reverse rotation of the lead screw 3, so that the moving plate 6 and the insert plate 10 are moved into the moving frame 1, and the transmission bar 24 is no longer limited by the limit block 11.This causes the transmission bar 24 to reset under the elastic action of the second return spring 25. Simultaneously, after the file is removed from the file slot, the baffle 20 resets inside the file slot. This allows the file to be placed inside the file slot, and the baffle 20 then presses against the telescopic spring 19, causing the baffle 20 to move the limiting ball 22 to the limiting hole 23 for automatic limiting, ensuring the stability of the baffle 20 inside the file slot. Furthermore, by setting a transmission opening and closing component inside the moving plate 6, when the fixed column 36 abuts the block 35, the blocking block 33 drives the sealing plate 32 to open the ventilation slot 31, allowing air to enter the ventilation slot 31. This allows air to enter the suction cup 7 after the moving plate 6 moves into the moving frame 1, releasing the file and achieving automatic unloading after the moving plate 6 moves the file into the moving frame 1. This completes the working principle of the positioning structure of the file management AGV robot.

[0059] In summary, in this invention, through the meshing connection between the movable frame 1 and the file rack 16, and under the action of the rack 17 and the gear disk 14, the user can precisely rotate the gear disk 14 via the electric motor 15. This allows the user to locate and search for files by precisely moving the gear disk 14 on the surface of the rack 17. Compared to the existing single identification camera 2 positioning, this method offers higher stability and accuracy. It also achieves precise docking with the file rack 16, resulting in a compact structure. Furthermore, by fixing a limiting block 11 to the outer wall of the insert plate 10, and with the limiting block 11 inside the transmission bar 24, the insert plate 10 can synchronously move the transmission bar 24 via the limiting block 11 during its movement. Furthermore, under the wedge-shaped action of the transmission bar 24, the transmission bar 24 moves under the action of the limiting block 11 via the insert plate 10, which stretches the second return spring 25. This causes the transmission bar 24 to press the limiting ball 22 at the bottom through the wedge structure at one end, preventing the limiting ball 22 from limiting the limiting hole 23. This causes the baffle 20 to reset under the extension spring 19, allowing the baffle 20 to push the file out of the file slot at the rear end. This facilitates the moving frame 1 to accurately adsorb the file at the front end using the suction cup 7, improving the accuracy of file docking. This solves the technical problem that the current positioning structure of the file management AGV robot cannot locate and position the file during retrieval to achieve accurate docking and facilitate stable retrieval and placement of the file.
