Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, and in particular to a transport vehicle structure with buffer function and an AGV transport vehicle. Background Technology

[0002] Traditional transport vehicles primarily function to move goods between different locations. Their typical operating mode is to pick up goods directly from a pickup point and immediately transport them to a delivery point, or return from a delivery point to a pickup point to continue picking up goods. However, in actual production and logistics processes, many complex situations arise. For example, in a logistics warehouse, when a transport vehicle arrives at a pickup point, the goods may not be ready due to issues in upstream processes, causing the vehicle to wait for a long time and reducing transport efficiency. Similarly, when a transport vehicle arrives at a delivery point, the downstream processes may not be ready to receive the goods, also causing the vehicle to stall. On a factory production line, the production rhythms of different processes may be inconsistent, and transport vehicles will face similar waiting problems during transportation. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a transport vehicle structure with a buffer function, which can solve the problems of insufficient buffer function and low transport efficiency in existing transport vehicles.

[0004] According to a first aspect embodiment of the present invention, a transport vehicle structure with a buffer function includes a vehicle body and a pick-up and place component and a buffer component respectively connected to the vehicle body. The buffer component is arranged adjacent to the pick-up and place component. The pick-up and place component includes a telescopic component and a gripping mechanism connected to the telescopic component. The telescopic component can drive the gripping mechanism to move above the buffer component so that the gripping mechanism can grab goods located in the buffer component or place goods in the buffer component. The buffer component includes a plurality of support members arranged vertically upward and downward, and the support members are used to support the placement of one or more goods.

[0005] The transport vehicle structure with buffer function according to the embodiments of this utility model has at least the following beneficial effects: By setting up a buffer component, when the transport vehicle encounters situations where the goods at the pickup point are not ready or the delivery point cannot receive the goods in time, it does not need to wait for a long time. The goods can be temporarily stored in the buffer component and other tasks can continue to be performed, thereby reducing the downtime of the transport vehicle and improving the overall transport efficiency. Furthermore, the buffer component includes multiple support members arranged vertically, making full use of the vertical space of the transport vehicle. Compared with the traditional simple temporary placement area, it greatly increases the buffer capacity and can meet the buffering needs of more goods. The pick-up and place-down components are arranged adjacent to the buffer component, and the pick-up and place-down components can adopt different gripping methods according to the characteristics of the goods, making the gripping and placement operations of the goods more flexible and convenient. At the same time, the support members of the buffer component can be adjusted in height or position as needed, further improving the efficiency of goods buffering and handling. In particular, the vehicle structure with buffer function proposed by this utility model is suitable for different working environments and types of goods. Whether it is standard goods in a logistics warehouse or irregularly shaped goods on a factory production line, efficient goods transportation and buffering can be achieved by adjusting the gripping method of the pick-up and place-down components and the layout of the support members of the buffer component.

[0006] According to some embodiments of the present invention, a plurality of the support members are arranged in parallel pairs and at equal intervals along the vertical direction, and the distance between two adjacent support members is sufficient to allow the picking and placing component to pass through in order to pick up / place goods.

[0007] Alternatively, multiple support members may be staggered in pairs along the vertical direction.

[0008] According to some embodiments of the present invention, the buffer component includes one or two columns, the columns are vertically arranged on the vehicle body, and the columns are fixed to the vehicle body by fasteners or integrally formed with the vehicle body, and a plurality of the support members are equidistantly and uniformly connected to the columns.

[0009] According to some embodiments of the present invention, the supporting member includes a support frame and a fall arrestor. The support frame and the fall arrestor are both connected to the column and located on the same side. The support frame is used to abut and support the goods, and the fall arrestor is disposed below the support frame to prevent the goods from falling.

[0010] According to some embodiments of this utility model, the support frame and the anti-fall plate are independently connected to the column;

[0011] Alternatively, the support frame is connected to the column, and the two ends of the fall arrestor are respectively connected to the support frame located on both sides;

[0012] Alternatively, the fall arrestor is connected to the column, and two support frames are provided, each connected to one side of the fall arrestor.

[0013] According to some embodiments of the present invention, the top of the support frame is provided with at least one limiting mechanism, which is capable of accommodating the auxiliary fasteners of the goods, and the auxiliary fasteners cooperate with the limiting mechanism to prevent the goods from falling off.

[0014] According to some embodiments of this utility model, the limiting mechanism is a limiting recess, the support frame is provided with a guide arc wall, the guide arc wall is arranged around the limiting recess, the auxiliary fixing member is a fixing rod, the fixing rod is arranged on the side wall of the goods, and the guide arc wall is used to guide the fixing rod into the limiting recess to prevent the goods from falling off.

[0015] According to some embodiments of the present invention, the picking and placing component includes a frame, and the telescopic component is disposed on the frame, including a fixed section, a first telescopic section and a second telescopic section. The fixed section is fixed to the frame, the first telescopic section is movably connected to the fixed section, the second telescopic section is movably connected to the movable end of the first telescopic section, and the gripping mechanism is connected to the movable end of the second telescopic section.

[0016] According to some embodiments of the present invention, the gripping mechanism includes two gripper drivers and two grippers. The two gripper drivers are respectively connected to the two grippers to independently drive the two grippers to move away from each other or relative to each other, so as to internally clamp the fixture or release the goods.

[0017] According to a second aspect of the present invention, the AGV transport vehicle includes a transport vehicle structure with a buffer function as described in any of the preceding claims.

[0018] The AGV transport vehicle according to the embodiments of this utility model has at least the following beneficial effects: By installing buffer components, pick-and-place components, and other structures on the AGV transport vehicle body and integrating them with the AGV transport vehicle's navigation and control systems, the AGV transport vehicle can automatically complete the tasks of buffering and transporting goods without manual intervention, greatly improving the efficiency and accuracy of logistics operations. Simultaneously, the buffering function can temporarily store goods, reducing waiting time, optimizing the logistics process, and lowering logistics costs.

[0019] Furthermore, since the buffer components include multiple vertically arranged support members, the method by which the pick-and-place component moves to be directly above the goods via a telescopic mechanism better accommodates this multi-layered buffer structure. The telescopic mechanism can accurately move the gripping mechanism to be directly above the goods on support members of different heights within a limited horizontal space, without requiring excessive horizontal movement space for the pick-and-place component. This allows the transport vehicle to interact more efficiently with the multi-layered buffer components within a limited vehicle space, making full use of vertical space and improving the overall space utilization of the transport vehicle structure. For example, this efficient use of space is particularly important in warehouse areas adjacent to compact automated production lines, allowing for an increase in the amount of buffered goods without increasing the transport vehicle's footprint, thus meeting the continuous operation requirements of the production line.

[0031] Reference Figure 1 , Figure 2and Figure 3 This utility model proposes a transport vehicle structure with a buffer function, including a vehicle body 100 and a pick-up and put-out component 200 and a buffer component 300 respectively connected to the vehicle body 100.

[0032] Specifically, the vehicle body 100 serves as the basic structure of the transport vehicle, providing mounting support for the loading / unloading components 200 and the buffer components 300, and driving the entire transport vehicle to achieve the function of transporting goods. The vehicle body 100 is typically equipped with a drive unit, steering unit, and navigation system to ensure that the transport vehicle can travel accurately along a predetermined route.

[0033] The pick-and-place component 200 includes a telescopic assembly 220 and a gripping mechanism 230 connected to the telescopic assembly 220. The telescopic assembly 220 can move the gripping mechanism 230 above the buffer component 300, enabling the gripping mechanism 230 to grip or place goods located in the buffer component 300. Specifically, the telescopic assembly 220 can be a device capable of linear telescopic movement, such as an electric push rod or a hydraulic cylinder. By controlling the telescopic length of the telescopic assembly 220, the position of the gripping mechanism 230 can be precisely adjusted. The gripping mechanism 230 can be designed in different forms, such as a vacuum suction cup or a mechanical gripper, according to the shape and characteristics of the goods, to ensure stable and reliable gripping and placement of goods. Through the telescopic assembly 220 and the gripping mechanism 230 of the pick-and-place component 200, goods can be easily transferred between the buffer component 300 and the transportation destination. Goods in the buffer component 300 can also be rearranged and combined according to actual needs, achieving flexible scheduling and orderly processing of goods to meet the needs of complex production or logistics scenarios.

[0034] It is easy to understand that the telescopic mechanism gives the pick-and-place component 200 flexible movement capabilities in the horizontal direction. In practical applications, the buffer component 300 may be set in different positions according to different cargo storage needs or the travel path planning of the transport vehicle. The pick-and-place component 200 can be moved directly above the cargo through the telescopic mechanism, allowing the transport vehicle to pick up and place cargo in different positions without precisely adjusting the overall position of the vehicle body 100. For example, in a large warehouse, the transport vehicle may need to shuttle between multiple shelves. When the buffer component 300 is located on one side of the transport vehicle's travel path and its position changes, the telescopic mechanism can quickly adjust the position of the pick-and-place component 200 to move it directly above the cargo for operation, without requiring the transport vehicle to frequently change its travel direction or make complex positioning adjustments, greatly improving the flexibility and adaptability of the transport vehicle in different operating scenarios.

[0035] The buffer component 300 consists of multiple support members 310 arranged vertically. This design makes full use of the vertical space of the transport vehicle, increasing the buffer capacity. Each support member 310 can support and place one or more goods, meeting the buffering needs of different goods. Moreover, the buffer component 300 is arranged adjacent to the pick-and-place component 200, allowing the pick-and-place component 200 to easily pick up goods located in the buffer component 300 or place goods in the buffer component 300, improving the buffering and handling efficiency of goods.

[0036] In some embodiments, the vehicle body 100 adopts a four-wheel drive structure and is equipped with a differential steering device and a laser navigation system. The laser navigation system can acquire the real-time location information of the transport vehicle and adjust the driving direction and speed of the transport vehicle through the control system to ensure that the transport vehicle can accurately reach the designated pick-up and delivery points. The pick-up and place component 200 adopts a mechanical gripper form, which consists of two openable and closable gripping arms. The inner side of the gripping arms is provided with anti-slip rubber pads to increase the friction with the goods and prevent the goods from slipping during the gripping and placement process. The mechanical gripper is driven by an electric push rod to realize the opening and closing action of the gripping arms. The buffer component 300 includes a plurality of support members 310 arranged vertically, each support member 310 is a rectangular flat plate structure with an anti-slip surface. The support members 310 are fixed to the bracket of the buffer component 300 by bolts, and the bracket is connected to the vehicle body 100.

[0037] In actual operation, when the transport vehicle arrives at the pickup point, if the goods are not yet ready, the transport vehicle does not need to wait; the pick-up and place unit 200 can organize or adjust the position of the previously buffered goods. Once the goods are ready, the pick-up and place unit 200 retrieves the goods from the pickup point and places them on the empty support 310 of the buffer unit 300. If the support 310 of the buffer unit 300 is full, the transport vehicle can transport some goods to the delivery point first, freeing up buffer space before continuing to pick up goods. When the transport vehicle arrives at the delivery point, if the downstream process is not yet ready to receive the goods, the transport vehicle can temporarily store the goods in the buffer unit 300. The pick-up and place unit 200 can, as needed, retrieve the goods from the buffer unit 300 one by one or in batches, waiting for the downstream process to be ready before proceeding with the delivery operation.

[0038] In other embodiments, the vehicle body 100 adopts a tracked structure, suitable for driving on complex terrain, such as areas with slopes or obstacles within a factory workshop. The vehicle body 100 is equipped with attitude sensing devices such as gyroscopes and accelerometers, enabling real-time monitoring of the vehicle's driving attitude and adjusting the track speed and steering via a control system to ensure the stability of the vehicle's movement. The pick-and-place component 200 uses vacuum suction cups, which generate negative pressure through a vacuum pump to adsorb and grasp goods. The number of vacuum suction cups can be adjusted according to the size and shape of the goods to improve the flexibility and reliability of grasping. The buffer component 300 includes multiple vertically arranged support members 310, each support member 310 being a circular pallet structure with edge guards to prevent goods from slipping during transport. The support members 310 are connected to the bracket of the buffer component 300 via an electric lifting mechanism, which can adjust the height of the support members 310 as needed, facilitating the pick-and-place component 200's grasping and placement of goods.

[0039] During operation, when transport vehicles move goods within the factory workshop, they may frequently encounter waiting situations due to the varying production rhythms of different processes. In these situations, the buffer component 300 can play a crucial role. For example, after a transport vehicle picks up goods from one process, if it finds that the next process is not yet ready, the transport vehicle can place the goods on the appropriate support 310 of the buffer component 300 and adjust the height of the support 310 as needed for better storage. When the next process is ready to receive goods, the pick-and-place component 200 can quickly and accurately remove the goods from the buffer component 300 and deliver them to the designated location.

[0040] Understandably, by setting up the buffer component 300, when the transport vehicle encounters situations where the goods at the pickup point are not ready or the delivery point cannot receive the goods in a timely manner, it does not need to wait for a long time. The goods can be temporarily stored in the buffer component 300, allowing the vehicle to continue performing other tasks, thereby reducing the transport vehicle's downtime and improving overall transport efficiency. Furthermore, the buffer component 300 includes multiple vertically arranged support members 310, making full use of the transport vehicle's vertical space. Compared to traditional simple temporary placement areas, it greatly increases the buffer capacity, meeting the buffering needs of more goods. The pick-and-place component 200 is arranged adjacent to the buffer component 300, and the pick-and-place component 200 can adopt different gripping methods according to the characteristics of the goods, making the gripping and placement operations more flexible and convenient. At the same time, the support members 310 of the buffer component 300 can be adjusted in height or position as needed, further improving the efficiency of goods buffering and handling. In particular, the vehicle body 100 structure with buffering function proposed in this utility model is suitable for different working environments and types of goods. Whether it's standard goods in a logistics warehouse or irregularly shaped goods on a factory production line, efficient cargo transportation and buffering can be achieved by adjusting the gripping method of the pick-and-place component 200 and the layout of the support component 310 of the buffer component 300.

[0041] Furthermore, the layout of the support components 310 has at least two embodiments. On one hand, multiple support components 310 are arranged in pairs, parallel and equidistant. Specifically, one or more support rods are vertically installed on the vehicle body 100, and multiple support components 310 are sequentially fixed longitudinally to the support rods, ensuring that adjacent support components 310 are parallel and equidistant. This spacing is precisely calculated to allow the picking and placing component 200, carrying the gripping mechanism 230, to pass smoothly. When it is necessary to pick up or place goods, the robotic arm can move freely between the support components 310, accurately reaching the location of the goods for operation. This arrangement facilitates the regular operation of the picking and placing component 200, allowing the robotic arm to move within a fixed interval according to a preset program, improving the accuracy and efficiency of picking and placing goods. Simultaneously, the equidistant arrangement also makes the structure of the buffer component 300 more regular, facilitating the classification, storage, and management of goods.

[0042] On the other hand, the multiple support components 310 are staggered in pairs. Specifically, the support structure is installed first, and then the support components 310 are fixed sequentially in a staggered manner. For example, the first layer of support components 310 is installed on the left side of the support structure, the second layer on the right side, the third layer back on the left side, and so on. This staggered arrangement allows the pick-and-place component 200 more flexibility when handling different layers of goods, avoiding interference between the robotic arm and adjacent support components 310 during vertical movement. The staggered arrangement increases the space utilization of the buffer component 300, allowing more support components 310 and goods to be placed in the limited vertical space. Moreover, the pick-and-place component 200 can avoid collisions with adjacent support components 310 during operation, reducing interference during operation and improving the stability and safety of the transport vehicle.

[0043] Furthermore, a robust column 320 with sufficient strength and stability is vertically welded to the center of one side edge of the vehicle body 100. Then, multiple support components 310 are evenly fixed to the column 320 using bolts, with the spacing between adjacent support components 310 rationally set according to the height of the goods and the operating space of the loading / unloading component 200. The design using a single column 320 is simple in structure, occupies little space, and is suitable for use in compact environments. At the same time, the centrally located column 320 helps to concentrate the center of gravity of the entire buffer component 300, improving the stability of the transport vehicle during operation.

[0044] On the other hand, refer to Figure 2 Two uprights 320 are symmetrically and vertically mounted on the vehicle body 100, with the distance between them designed according to the width of the cargo. The two ends of a support member 310 are bolted to the two uprights 320, ensuring the support member 310 is horizontal and stable. Multiple support members 310 are equidistantly and evenly distributed between the two uprights 320, forming a stable buffer structure. The two uprights 320 provide stronger support, capable of bearing heavier cargo. Furthermore, the space between the two uprights 320 better restricts cargo movement, ensuring cargo stability during buffering. In addition, this structure facilitates the installation, disassembly, and maintenance of the support members 310.

[0045] To ensure the stable support of the support component 310, the support component 310 includes a support frame 311 and a fall arrestor 312. When installing the support component 310 on the column 320, the support frame 311 and the fall arrestor 312 are first connected to the column 320 respectively. The support frame 311 is made of a metal material with a certain strength and is fixed horizontally to the column 320 to directly abut and support the bottom of the goods. The fall arrestor 312 is installed below the support frame 311, parallel to the support frame 311 and maintaining a certain distance, generally about 1 / 3 of the height of the goods. The fall arrestor 312 is firmly connected to the column 320 by bolts or welding. When the goods slide or tilt on the support frame 311, the fall arrestor 312 can prevent the goods from falling.

[0046] The combined design of the support frame 311 and the fall arrestor 312 greatly improves the safety of goods during the buffering process. The support frame 311 bears the weight of the goods, while the fall arrestor 312, as a second line of defense, effectively avoids the risk of goods falling due to accidents, reduces the possibility of damage to the goods, and also ensures the safety of surrounding personnel.

[0047] In some embodiments, two support frames 311 are installed on both sides of the fall arrestor 312, and the support frames 311 are connected to the fall arrestor 312 and the column 320 by bolts. The distance between the two support frames 311 is designed according to the length of the goods to ensure that they can respectively abut and support both ends of the goods. For example, for goods with a length of 1 meter, the distance between the two support frames 311 is set to about 0.9 meters, so that the goods can be stably placed on the support frames 311. The design of double support frames 311 can more evenly distribute the weight of the goods, reduce the force on a single support frame 311, and improve the stability of the support. At the same time, supporting both ends of the goods can prevent the goods from shaking or tilting during the buffering process, ensuring the stability of the goods during storage, which is especially suitable for buffering long and narrow goods.

[0048] It should be noted that the support frame 311 and the fall arrestor 312 are independently connected to the column 320. Specifically, the support frame 311 and the fall arrestor 312 are directly fixed to the column 320 using bolts, and each component has an independent connection point. This connection method makes the installation and adjustment of each component more flexible, allowing for fine-tuning of the position of the support frame 311 or the fall arrestor 312 individually according to actual needs. This facilitates installation and disassembly, making it easy to repair and replace individual components. Furthermore, the position and angle of the support frame 311 and the fall arrestor 312 can be flexibly adjusted according to different cargo types and buffering requirements.

[0049] In other embodiments, the support frame 311 is connected to the column 320, and the two ends of the fall arrestor plate 312 are respectively connected to the support frames 311 located on both sides. Specifically, the support frame 311 is first fixed to the column 320, and then the two ends of the fall arrestor plate 312 are fixed to the support frames 311 on both sides by welding or bolting. This structure makes the fall arrestor plate 312 and the support frame 311 form a whole, enhancing the stability of the entire support component 310. This structure makes the overall structure more stable, with the fall arrestor plate 312 and the support frame 311 supporting each other, able to withstand greater cargo weight and external impact, improving the reliability and durability of the buffer component 300.

[0050] In other embodiments, the fall arrestor 312 is connected to the column 320, and two support frames 311 are respectively connected to both sides of the fall arrestor 312. Specifically, the fall arrestor 312 is vertically fixed to the column 320, and then the two support frames 311 are respectively installed on both sides of the fall arrestor 312 and connected by bolts or welding. This design makes the fall arrestor 312 the main support structure, while the support frames 311 play a supporting role for the cargo. This structure allows the fall arrestor 312 to better prevent cargo from falling, while the support frames 311 can more accurately adapt to the shape and size of the cargo, providing more stable support.

[0051] To further enhance the stability of cargo buffering, the top of the support frame 311 has one or more limiting mechanisms 313. The cargo itself or the fixture on which it is placed has corresponding auxiliary fasteners. The shape and size of the limiting mechanism 313 are designed according to the auxiliary fasteners of the cargo. For example, if the auxiliary fastener is cylindrical with a diameter of 5 cm, then the limiting mechanism 313 can be designed as a semi-circular groove or a circular hole with a diameter slightly larger than 5 cm to ensure that the auxiliary fastener can be smoothly inserted. When the cargo is placed on the support frame 311, the auxiliary fastener will naturally fall into the limiting mechanism 313. The outer wall of the fixing rod abuts tightly against the side wall of the limiting mechanism 313, thereby restricting the horizontal movement of the cargo and preventing it from falling off. The design of the limiting mechanism 313 provides additional fixing points for the cargo, further enhancing the stability of the cargo during buffering. Especially when the transport vehicle is moving or subjected to external vibrations, the limiting mechanism 313 can effectively prevent the cargo from slipping off the support frame 311 due to shaking, improving the safety of cargo buffering.

[0052] Reference Figure 3The limiting mechanism 313 can be a limiting recess, and the auxiliary fixing component for the goods can be a fixing rod extending from the side of the goods, or the goods can be placed on a fixture with a fixing rod on its side. A guide arc wall 314, machined from metal, is formed around the limiting mechanism 313 on the top of the support frame 311. The curvature of the guide arc wall 314 is carefully designed to naturally guide the fixing rod extending from the periphery of the goods into the limiting recess. For example, the initial end of the guide arc wall 314 forms an angle of approximately 30 degrees with the surface of the support frame 311, gradually transitioning to connect with the limiting recess, forming a smooth guide surface. When the operator or the loading / unloading component 200 places the goods on the support frame 311, the fixing rod smoothly engages with the limiting recess along the guide arc wall 314, eliminating the need for precise alignment and improving operational convenience. The guide arc wall 314 greatly simplifies the goods placement process, eliminating the need for operators to spend excessive time and effort precisely adjusting the goods' position to align the fixing rod with the limiting recess. This not only improves work efficiency, but also reduces the risk of goods being unstable or damaged due to improper operation, thus enhancing the practicality and reliability of the entire transport vehicle's buffer function.

[0053] Reference Figure 1 It should be noted that the pick-and-place component 200 includes a frame 210, which is constructed from aluminum alloy profiles, featuring light weight, high strength, and ease of assembly. The telescopic component 220 is mounted on the frame 210 and specifically includes a fixed section 221, a first telescopic section 222, and a second telescopic section 223. The fixed section 221 can be a rectangular metal tube, securely fixed to the frame 210 with bolts. It has an internal guide rail to provide precise guidance for the telescopic movement of the first telescopic section 222, ensuring the smoothness and straightness of the telescopic process. The first telescopic section 222 can slide smoothly within the guide rail of the fixed section 221.

[0054] Optionally, a drive motor and a lead screw transmission mechanism are installed inside the first telescopic section 222. The drive motor is connected to the lead screw through a coupling. When the drive motor rotates, the lead screw drives the nut to move, thereby pushing the first telescopic section 222 to telescopically move relative to the fixed section 221.

[0055] Optionally, a limit switch is provided on the side of the first telescopic section 222. When the telescopic section reaches its limit position, the limit switch will send a signal to the control system to stop the operation of the drive motor and prevent excessive telescopic movement from damaging the equipment.

[0056] Optionally, the structure of the second telescopic section 223 is similar to that of the first telescopic section 222, and it is movably connected to the movable end of the first telescopic section 222. It also uses a lead screw drive for telescopic movement and is similarly equipped with a limit switch. The movable end of the second telescopic section 223 is connected to the gripping mechanism 230.

[0057] The telescopic assembly 220 of the pick-and-place component 200 adopts a two-section telescopic structure, including a first telescopic section 222 and a second telescopic section 223. This two-section design allows the gripping mechanism 230 to make more precise position adjustments in both the horizontal and vertical directions. Each telescopic section is driven by an independent servo motor and ball screw pair, and in conjunction with a high-precision displacement sensor, it enables precise control of the telescopic length, with errors kept within a very small range. During the process of moving the gripping mechanism 230 directly above the cargo or buffer component 300, it ensures millimeter-level positional accuracy, greatly improving the accuracy of cargo gripping and placement, and reducing cargo damage and operational failures caused by positional deviations. This makes it particularly suitable for applications requiring extremely high positional accuracy, such as the assembly of electronic components and the storage of precision instruments.

[0058] Furthermore, the two telescopic guide mechanisms utilize high-precision linear guides, characterized by low friction and high rigidity, effectively reducing friction and vibration during the telescopic process. During telescopic movement, the first telescopic section 222 and the second telescopic section 223 work together to extend and retract smoothly, making the movement of the gripping mechanism 230 and the cargo more stable. This smooth movement prevents collisions and damage to goods during transport, especially for fragile or easily deformable goods such as glass and ceramic products, providing crucial protection and improving the safety and reliability of cargo transportation.

[0059] Furthermore, by controlling the extension lengths of the first telescopic section 222 and the second telescopic section 223 respectively, the gripping mechanism 230 can move more extensively in three-dimensional space, adapting to the needs of gripping and placing goods at different heights and locations. Whether retrieving goods in confined spaces or storing goods on high shelves, the transport vehicle can respond flexibly without frequent adjustments to its position, improving work efficiency and operational convenience. For example, in large warehouses, goods may be distributed across different floors and areas; the two-section telescopic design allows the transport vehicle to easily complete cross-floor and cross-area goods transportation tasks.

[0060] Reference Figure 4Furthermore, the gripping mechanism includes two gripper drive members 231 and two grippers 232. The two gripper drive members 231 drive the two grippers 232 to move back-to-back or relative to each other, thereby internally clamping or releasing the fixture. Specifically, when the fixture needs to be gripped, the two gripper drive members 231 drive the two grippers 232 to move relative to each other, causing the grippers 231 to extend into the fixture. Then, the two grippers 232 are driven to move back-to-back, achieving internal clamping through the friction and supporting force between the grippers 231 and the inner wall of the fixture, ensuring that the fixture is firmly gripped. When the fixture needs to be released, the two gripper drive members 231 drive the two grippers 232 to move relative to each other, reducing the pressure between the grippers 232 and the inner wall of the fixture, thereby releasing the fixture. It should be noted that the fixture here is a battery cell forming fixture, which is provided with a fixing part for the grippers 232 to internally clamp.

[0061] Understandably, by employing the internal clamping principle, the gripper 232 clamps from within the fixture, unaffected by external shape and dimensional errors. This allows for more accurate positioning of the clamping point, ensuring a secure clamping of the fixture each time. This avoids the problems of incomplete or misaligned clamping that often occur with external gripping, significantly improving the accuracy and stability of the gripping process. The internal clamping method does not damage the outer surface of the fixture, effectively extending its service life compared to external gripping, ensuring its precision and performance, and reducing production costs. For fixtures of different shapes and sizes, as long as there is suitable internal space for the gripper 232 to extend and clamp, the material handling component with positioning and correction functions of this invention can achieve accurate gripping, demonstrating strong adaptability and versatility.

[0062] Therefore, because the two-stage telescopic mechanism enables precise positioning and smooth movement of the gripping mechanism 230, it reduces the need for multiple operations due to inaccurate positioning, thereby significantly shortening the time for grabbing and placing goods and improving the working efficiency of the transport vehicle. Simultaneously, the smooth movement reduces wear and tear on mechanical components and energy consumption, lowering the operating costs of the transport vehicle. Compared to traditional single-stage telescopic or fixed gripping mechanisms 230, the transport vehicle of this embodiment can complete more cargo transportation tasks in the same working time with lower energy consumption, exhibiting greater economic and environmental benefits.

[0063] This utility model also proposes an AGV transport vehicle, including the transport vehicle structure with buffer function described in any of the above claims, integrating the aforementioned buffer function transport vehicle structure onto the AGV transport vehicle. A buffer component 300, a pick-and-place component 200, and other structures are installed on the AGV transport vehicle body 100 and integrated with the AGV transport vehicle's navigation and control systems. Through the navigation system, the AGV transport vehicle can automatically drive to the designated cargo storage location, then use the pick-and-place component 200 to grab the cargo and place it in the buffer component 300; when cargo needs to be transported, it is retrieved from the buffer component 300 for transport. This fully leverages the automation advantages and high efficiency of the buffer function of the AGV transport vehicle. The AGV transport vehicle can automatically complete cargo buffering and transportation tasks without manual intervention, greatly improving the efficiency and accuracy of logistics operations. Simultaneously, the buffer function can temporarily store cargo, reducing cargo waiting time, optimizing the logistics process, and lowering logistics costs.

[0064] Furthermore, since the buffer component 300 includes multiple vertically arranged support members 310, the method by which the pick-and-place component 200 moves to be directly above the goods via the telescopic mechanism can better adapt to this multi-layer buffer structure. The telescopic mechanism can accurately move the gripping mechanism 230 directly above the goods on the support members 310 at different heights within a limited horizontal space, without requiring excessive horizontal movement space for the pick-and-place component 200. This allows the transport vehicle to interact more efficiently with the multi-layer buffer component 300 within the limited space of the vehicle body 100, making full use of vertical space and improving the overall space utilization of the transport vehicle structure. For example, this efficient use of space is particularly important in warehouse areas adjacent to some compact automated production lines, allowing for an increase in the amount of buffered goods without increasing the transport vehicle's footprint, thus meeting the continuous operation requirements of the production line.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
