Description

Technical Field

[0001] This utility model relates to the field of AGV robot technology, specifically to an AGV telescopic material box clamping mechanism. Background Technology

[0002] AGV (Automated Guided Vehicle) robots are widely used in logistics and warehousing for automated material handling. However, current technologies present challenges when AGV robots handle deep material boxes. Common gripper mechanisms are bulky and space-consuming, making them ineffective in coordinating with telescopic mechanisms within confined multi-tiered shelving spaces. This prevents AGV robots from successfully placing material boxes on lifting platforms, impacting operational efficiency and flexibility. Existing solutions typically rely on complex mechanical structures, resulting in high costs and inconvenient maintenance. Therefore, a space-optimized, structurally simple gripping mechanism is urgently needed to address these issues. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an AGV telescopic bin clamping mechanism to solve the technical problem that the traditional solution is large in size, occupies a lot of space, and cannot be effectively linked with the telescopic mechanism in the narrow multi-layer shelf space. Through compact design, the clamping mechanism and the telescopic mechanism are linked, reducing space occupation and improving applicability in narrow environments.

[0004] To solve the above problems, the technical solution provided by this utility model is as follows:

[0005] An AGV telescopic bin clamping mechanism includes an execution fixing mechanism, a drive motor, a crossbar, and a central drive shaft. The drive motor is connected to the central drive shaft, and the end of the crossbar is connected to the central drive shaft. The crossbar is mounted on the central drive shaft and can be driven by the drive motor to rotate circumferentially along the central drive shaft. The crossbar is perpendicular to the axial direction of the central drive shaft.

[0006] The core components of the gripping mechanism are defined, and a compact layout is achieved through the integrated design of the execution fixing mechanism, drive motor, crossbar, and central drive shaft. Functionally, it ensures direct linkage between the source of the gripping action (drive motor) and the execution component (crossbar), thus solving the problem of large space occupation in gripper mechanisms in the prior art. The crossbar is set perpendicular to the central drive shaft, optimizing space utilization and making the mechanism more suitable for AGV robots to operate in confined environments such as multi-layer shelves.

[0007] Optionally, the execution fixing mechanism includes a bolt, a washer, a retaining ring, a bearing, and a fixing connecting block. The bolt passes through a through hole at the rotating end of the crossbar, the washer is disposed at both ends of the through hole, the crossbar is fixed to the central drive shaft by the bolt, and the fixing connecting block has a cavity for accommodating the central drive shaft. The crossbar and the central drive shaft are rotatably connected to the inner wall of the cavity of the fixing connecting block by a retaining ring and a bearing.

[0008] The components of the fixing mechanism have been refined. Functionally, the combination of bolts, washers, snap rings, bearings, and fixing blocks provides structural stability and smooth rotation. It solves the defects of loosening or excessive friction in the prior art, ensuring precise and reliable clamping action. The cavity design of the fixing blocks further optimizes space utilization, making the overall mechanism more compact.

[0009] Optionally, the fixed connecting block is provided with two limiting protrusions that abut against the crossbar, and the rotating part of the crossbar is provided with an arc protrusion. The body of the crossbar and the arc protrusion respectively cooperate with the two limiting protrusions to abut and limit the movement.

[0010] By controlling the rotation range of the crossbar through a limiting structure, it functionally prevents damage to the mechanism or operational errors caused by excessive rotation, thus improving safety. It directly addresses the problem in the background technology where gripper mechanisms may become uncontrollable in confined spaces, ensuring controllable movement through mechanical limiting.

[0011] Optionally, the crossbar can rotate within a range of 90° to 110°.

[0012] The rotation angle range has been optimized, enabling the mechanism to adapt to material boxes of different sizes, thus improving its versatility and flexibility. It overcomes the shortcomings of previous gripper mechanisms, which, due to their fixed rotation range, could not handle diverse scenarios, thereby enhancing the adaptability of AGV robots.

[0013] Optionally, the clamping mechanism is linked to and electrically connected to the secondary telescopic mechanism. When the secondary telescopic mechanism extends, the crossbar rotates inward to clamp the material box. When the secondary telescopic mechanism retracts, the crossbar remains in the clamping state.

[0014] Functionally, it automates the picking and placing process, solving the problem of the gripper and telescopic mechanism becoming disconnected in the background technology. Electrical connection ensures synchronous control, reducing manual intervention and improving operational efficiency in multi-layer racking environments.

[0015] Optionally, the ends of the crossbar are provided with rounded corners.

[0016] The rounded corner design reduces damage to the material bins, improving operational safety and material protection. It addresses the issue of sharp edges potentially scratching materials in the prior art, demonstrating a user-friendly design.

[0017] Optionally, the drive motor is connected to the central drive shaft via a set screw.

[0018] This design ensures a secure connection between the drive motor and the transmission shaft, preventing loosening during transmission and improving transmission efficiency and reliability. It solves the efficiency loss problem caused by loose connections in the prior art and is suitable for frequent start-stop scenarios of AGV robots.

[0019] Alternatively, the crossbar is supported on the central drive shaft by bearings.

[0020] By reducing rotational friction through bearing support, the durability and smoothness of the mechanism are improved. It addresses the problem of short lifespan due to high friction in the prior art, ensuring long-term stable operation of the clamping action.

[0021] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0022] The technical solution provided by this utility model significantly reduces space occupation through a compact design, and the overall structure optimizes the layout of AGV robots in narrow, multi-layered shelves, solving the defects of traditional grippers that are too large and cannot effectively coordinate. Secondly, the structure is simple and durable, with the execution and fixing mechanism using components such as bolts, washers, snap rings, and bearings, ensuring stability and low maintenance costs. In addition, the efficient connection between the drive motor and the central transmission shaft, secured by set screws, achieves reliable transmission, improving operational accuracy and lifespan. Finally, it is low-cost and widely applicable; the controllable rotation of the crossbar (rotation range up to 100°) and its linkage with the secondary telescopic mechanism achieve automated picking and placing, enhancing the practicality and efficiency of AGV robots in logistics scenarios. Overall, these effects collectively improve the reliability, economy, and adaptability of the AGV system. Attached Figure Description

[0029] Example 1

[0030] Combined with appendix Figure 1-4 An AGV telescopic material box clamping mechanism includes an execution fixing mechanism 101, a drive motor 102, a crossbar 3, and a central drive shaft 6. The drive motor 102 is connected to the central drive shaft 6, and the end of the crossbar 3 is connected to the central drive shaft 6. The crossbar 3 is mounted on the central drive shaft 6 and can be driven by the drive motor 102 to rotate circumferentially along the central drive shaft 6. The crossbar 3 is perpendicular to the axial direction of the central drive shaft 6. After the drive motor 102 starts, it transmits the rotational motion to the central drive shaft 6 through a transmission mechanism. The central drive shaft 6 serves as the rotation axis, driving the crossbar 3 to rotate circumferentially. Because the crossbar 3 is perpendicular to the axial direction, it forms a clamping or releasing action during rotation, thereby realizing the picking and placing of the material box. The entire process reduces component complexity and improves reliability through a simple shaft transmission system. The overall structure is as follows: Figure 4 As shown, the linkage between the mechanism and the telescopic mechanism is illustrated.

[0031] The fixing mechanism 101 includes a bolt 1, a washer 2, a retaining ring 4, a bearing 5, and a fixing block 7. The bolt 1 passes through a through hole at the rotating end of the crossbar 3. The washer 2 is disposed at both ends of the through hole. The crossbar 3 is fixed to the central drive shaft 6 by the bolt 1. The fixing block 7 has a cavity for accommodating the central drive shaft 6. The crossbar 3 and the central drive shaft 6 are rotatably connected to the inner wall of the cavity of the fixing block 7 by the retaining ring 4 and the bearing 5. The bolt 1 and the washer 2 are fastened through the through hole of the crossbar 3 to prevent relative movement between the crossbar 3 and the central drive shaft 6. The bearing 5 is installed in the cavity of the fixing block 7 to reduce rotational friction; the retaining ring 4 acts as an axial limit to prevent the components from falling off. The fixing block 7 serves as a support base to ensure the stability of the central drive shaft 6 and the crossbar 3 during rotation. The component arrangement of the fixing mechanism 101 is as follows: Figure 1 As shown, this reflects the detailed design.

[0032] The fixed connecting block 7 has two limiting protrusions that abut against the crossbar 3. The rotating part of the crossbar 3 has an arc-shaped protrusion. The body of the crossbar 3 and the arc-shaped protrusion respectively cooperate with the two limiting protrusions to abut and limit the movement. The limiting protrusions on the fixed connecting block 7 and the arc-shaped protrusion on the rotating part of the crossbar 3 form abutment points during rotation. When the crossbar 3 rotates to a preset angle, the arc-shaped protrusion contacts the limiting protrusions, generating a stopping force to limit further rotation. This design is simple and durable, requires no additional sensors, and reduces costs. The rotation mechanism of the crossbar 3 is as follows: Figure 3 As shown, the limit details are illustrated.

[0033] The rotation range of the crossbar 3 is 90° to 110°. Based on the limiting structure, the rotation range is precisely set between 90° and 110°. When the drive motor 102 rotates the crossbar 3, the limiting protrusion ensures that the angle does not exceed this range, thus ensuring clamping force while avoiding excessive compression when gripping the material box. The selection of the angle range balances space occupation and operational efficiency. In this embodiment, the rotation range can be 90°, 100°, or 110°.

[0034] The clamping mechanism 201 is linked and electrically connected to the secondary telescopic mechanism 202. When the secondary telescopic mechanism 202 extends, the crossbar 3 rotates inward to clamp the material box; when the secondary telescopic mechanism 202 retracts, the crossbar 3 maintains the clamping state. When the secondary telescopic mechanism 202 extends, it triggers the drive motor 102 via an electrical signal, causing the crossbar 3 to rotate inward to clamp the material box; when retracting, the crossbar 3 maintains the clamping state, relying on the mechanism's self-locking or the motor to maintain torque. This linkage ensures that the material box is stably brought back to the AGV robot, and the overall process is as follows: Figure 4 As shown, this demonstrates spatial optimization.

[0035] The ends of crossbar 3 are rounded. These rounded ends distribute pressure smoothly upon contact with the material box, preventing stress concentration. This reduces friction and impact, extending the lifespan of both the mechanism and the material box. The rounded corner design facilitates machining and does not compromise the overall structural compactness.

[0036] The drive motor 102 is connected to the central drive shaft 6 via a set screw. The set screw is screwed into the output shaft of the drive motor 102 or the end of the central drive shaft 6, generating radial pressure to achieve a gapless fixation. This connection method is simple, efficient, and easy to install and maintain. Details of the connection between the drive motor 102 and the central drive shaft 6 are as follows: Figure 2 As shown.

[0037] The crossbar 3 is supported on the central drive shaft 6 by bearings 5. The inner ring of the bearing 5 mates with the central drive shaft 6, and the outer ring mates with a fixed part (such as a fixed connecting block 7), minimizing resistance when the crossbar 3 rotates. This reduces the motor load and wear. The bearing 5 is arranged as follows: Figure 1 As shown, it is integrated with the fixed execution mechanism 101.

[0038] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
