Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, specifically to an AGV that integrates the front and rear axles of an automobile. Background Technology

[0002] In modern industrial assembly processes, the safety and efficiency of automotive rear axle assembly are key research areas. The adjustable rear axle lifting mechanism is one of the important pieces of equipment on the assembly line, and its protective portion typically uses a V-shaped shield. This shield not only protects the equipment but also reduces the intrusion of foreign objects to a certain extent.

[0003] However, the current V-shaped protective cover has a smooth surface, which cannot provide safe standing support for operators, causing numerous problems during assembly. For example, in situations where the rear axle assembly space is limited, operators standing on the cover to perform tasks are highly slippery due to the smooth surface, posing a significant safety hazard. Furthermore, prolonged foot traffic on the cover can damage it, potentially jeopardizing the normal operation of the equipment. In addition, existing Automated Guided Vehicle (AGV) personnel platforms often employ a stepped layout, with a platform height typically 400mm from the ground. This design requires accommodating equipment such as servos and batteries within a limited space, resulting in a relatively high platform. During operation, personnel standing on the platform are prone to inconvenience and even safety hazards due to the height difference, especially during prolonged work or when frequent platform access is required. Utility Model Content

[0004] The purpose of this invention is to provide an AGV that integrates the front and rear axles of a car, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an AGV (Automated Guided Vehicle) with integrated front and rear axles, comprising:

[0006] The vehicle body, the upper surface of which is horizontal;

[0007] Lifting mechanism, two of which are mounted on the top of the vehicle body, the lifting mechanism being able to lift or lower vertically, one of which is able to slide on the vehicle body;

[0008] A front axle fixing structure is mounted on a sliding lifting mechanism;

[0009] A rear axle fixing structure is mounted on another of the aforementioned lifting mechanisms;

[0010] Patterned steel plate cover, which is laid on the upper surface of the vehicle body.

[0011] Preferably, the lifting mechanism includes a base, which is fixed to the top of the vehicle body. A scissor-type lifting device is provided on the top of the base. The scissor-type lifting device includes two lifting rods that rotate relative to each other. A lifting platform is fixed to the top of the scissor-type lifting device.

[0012] Preferably, the top of the lifting platform is fixedly connected with multiple lifting rings.

[0013] Preferably, the bottom of the slidable lifting mechanism slides via an electric gear rack.

[0014] Preferably, the two lifting mechanisms are on the same horizontal axis.

[0015] Preferably, a standing platform is located next to the top lifting mechanism of the vehicle body, and the patterned steel plate cover is laid on the top of the standing platform.

[0016] Preferably, the height of the standing platform is less than 400mm and is flush with the bottom of the lifting mechanism.

[0017] Preferably, the vehicle body is equipped with a servo motor and a battery module, and the battery module provides power support for the standing platform and the lifting mechanism.

[0018] Preferably, the scissor-type lifting device of the lifting mechanism is hydraulically driven.

[0019] Preferably, the lifting platform at the top of the scissor-type lifting device is provided with an anti-slip coating.

[0020] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0021] This AGV, which integrates the front and rear axles of a vehicle, uses reinforced patterned steel plates as guards. This not only provides reliable protection but also supports the weight of the operators, avoiding the slippery risk caused by the smooth surface of traditional V-shaped guards. This improves the safety and working space for operators during rear axle assembly. Meanwhile, the tread pattern design further increases friction, reducing the risk of accidents caused by slippery environments and extending the service life of the protective cover. The optimized lifting mechanism design, with one of the lifting mechanisms capable of sliding, combined with a scissor-type lifting device and a lifting platform, allows for flexible adjustment of the front and rear axle assembly positions to adapt to the axle spacing requirements of different vehicle models, further improving the accuracy and efficiency of the assembly process. By reconfiguring the servo motor, battery module, and load-bearing wheels, the overall height of the personnel platform is lowered to below 400mm and aligned with the bottom of the lifting mechanism, effectively reducing the risk of falls due to height differences for operators. The optimized equipment structure also improves the ease of use of the personnel platform. The overall vehicle body design is stable, with the lifting mechanisms on the same horizontal axis, effectively reducing swaying and imbalance during operation, improving the safety and stability of assembly work. The distance between the front and rear axle fixing structures is adjustable, allowing for flexible adjustment of the fixing positions according to the dimensions of the front and rear axles, accommodating various specifications of front and rear axle components. This avoids the problem of traditional equipment limiting the assembly range due to a single fixing structure, improving the equipment's applicability. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 and Figure 2As shown, an AGV (Automated Guided Vehicle) with front and rear axles includes a vehicle body 1 with a horizontal upper surface; two lifting mechanisms 2 disposed on top of the vehicle body 1, each capable of vertically lifting or lowering, one of which can slide on the vehicle body 1; a front axle fixing structure 3 disposed on the sliding lifting mechanism 2; a rear axle fixing structure 4 disposed on the other lifting mechanism 2; and a patterned steel plate cover 6 laid on the upper surface of the vehicle body 1.

[0027] This embodiment provides a stable platform support through the vehicle body 1, and two lifting mechanisms 2 lift the front and rear axles respectively to meet assembly requirements. One lifting mechanism 2 is slidable to adapt to different front and rear axle positions. The front axle fixing structure 3 and rear axle fixing structure 4 are existing fixing structures, respectively fixing the corresponding axle components to ensure stability and accuracy during assembly. The patterned steel plate guard 6 enhances the platform's anti-slip performance, ensuring operator safety. This invention, by setting two independently operable lifting mechanisms on the vehicle body, achieves independent lifting and lowering operations for the front and rear axles, effectively improving assembly efficiency. Furthermore, the sliding mechanism increases the system's flexibility, adapting to the front and rear axle assembly requirements of different vehicle models. The patterned steel plate guard 6 provides additional anti-slip protection, improving the equipment's safety and practicality.

[0028] In other embodiments, the vehicle body 1 can be made of aluminum alloy to reduce the weight of the equipment, or a detachable design can be added to the patterned steel plate cover 6 for easy maintenance. At the same time, the sliding lifting mechanism 2 can achieve the sliding function through other drive methods (such as chain drive) to adapt to different scenario requirements.

[0029] In one possible implementation, a lifting mechanism 2 for an AGV (Automated Guided Vehicle) assembling front and rear axles includes a base 21 fixed to the top of the vehicle body 1. A scissor-type lifting device 22 is mounted on the top of the base 21. The scissor-type lifting device 22 includes two mutually rotating lifting rods 221. A lifting platform 23 is fixed to the top of the scissor-type lifting device 22. The base 21 provides stable support for the scissor-type lifting device 22. Through the coordinated movement of the lifting rods 221 of the scissor-type lifting device 22, the lifting platform 23 can achieve vertical lifting, thereby meeting the height adjustment requirements during assembly. The scissor-type lifting device 22 has a simple structure, high stability, is easy to maintain and operate, and can bear a large load. The design of the lifting platform 23 further enhances the practicality of the lifting mechanism, adapting to the load-bearing requirements of different components.

[0030] In other embodiments, the lifting rod 221 of the scissor lift 22 can be made of composite materials to reduce weight or enhance corrosion resistance. The base 21 can also be modularly designed for quick disassembly and replacement to adapt to the needs of different working environments.

[0031] In one possible implementation, a lifting platform 23 for an AGV assembling front and rear axles of an automobile is fixedly connected to the top of multiple lifting rings 5. The lifting platform 23 is connected to lifting equipment via the lifting rings 5, facilitating precise position adjustment of the front and rear axles or other heavy components. The distributed design of the multiple lifting rings makes the load more even, further enhancing the reliability of the system. The lifting rings 5 ​​provide additional support for the assembly of heavy components, reducing the workload of manual adjustments, while improving the efficiency and accuracy of the overall assembly.

[0032] The shape of the lifting ring 5 can be optimized according to the type of the load-bearing component, for example, using an elliptical ring to accommodate a larger load. Furthermore, the position and number of the lifting rings can be adjusted according to the dimensions of the lifting platform 23 to meet different assembly requirements.

[0033] In one possible implementation, the bottom of a sliding lifting mechanism 2 in an AGV for assembling front and rear axles of an automobile slides via an electric gear and rack mechanism. The electric gear and rack structure is driven by an electric motor to rotate the gears, which mesh with the rack to achieve linear sliding of the lifting mechanism 2, ensuring a smooth sliding process and precise positioning. This sliding structure simplifies the platform movement operation while guaranteeing positioning accuracy, making it suitable for front and rear axle assembly scenarios requiring high-precision adjustments.

[0034] The sliding mechanism can be replaced by a ball screw drive or a linear motor to meet the requirements of higher loads or faster sliding. Furthermore, the sliding range can be adjusted by changing the rack length or drive stroke, further enhancing the system's adaptability.

[0035] In one possible implementation, in an AGV for assembling front and rear axles of a vehicle, two lifting mechanisms 2 are positioned on the same horizontal axis. The two lifting mechanisms 2 are arranged along the same horizontal axis on the top of the vehicle body 1, ensuring that the front and rear axles are installed at the same height and in a straight line, avoiding assembly errors. This arrangement allows for more efficient and precise installation of the axle assembly. The horizontal axis arrangement of the lifting mechanisms significantly improves assembly accuracy, avoiding difficulties in assembling the axle assembly due to height differences or misalignment. Furthermore, this arrangement simplifies equipment design and reduces manufacturing costs.

[0036] The lifting mechanism can be adjusted to different horizontal axis positions according to the specific vehicle model to adapt to different assembly requirements. When tilting is required for certain vehicle models, the lifting mechanism can also be designed with an adjustable angle.

[0037] In one possible implementation, a standing platform 7 is provided next to the lifting mechanism 2 on top of the vehicle body 1 in an AGV for assembling front and rear axles. A patterned steel plate cover 6 is laid on top of the standing platform 7. The standing platform 7 provides a safe and convenient working area for operators, who can stand on the platform to perform assembly work. The patterned steel plate cover 6 further improves the anti-slip performance of the standing platform, ensuring personnel safety. By setting up the standing platform 7 next to the lifting mechanism 2, the convenience of operation for operators is significantly improved, while avoiding potential safety hazards caused by unstable standing positions. The application of the patterned steel plate cover further enhances safety.

[0038] The height and size of the platform 7 can be adjusted according to operational needs, and the material of the protective cover 6 can be selected from aluminum alloy or high-strength composite materials depending on the usage environment. In addition, guardrails can be added to the edge of the platform to further improve safety.

[0039] In one possible implementation, the height of the standing platform 7 in an AGV for assembling front and rear axles of an automobile is less than 400mm, and it is flush with the bottom of the lifting mechanism 2. The height of the standing platform 7 is designed to be less than 400mm to facilitate operator access, while maintaining flushness with the bottom of the lifting mechanism 2 ensures that operators can get closer to the assembly position, thereby improving work efficiency. The low height design of the standing platform makes operation more ergonomic, reducing the physical strain on operators from prolonged bending. The flush design with the bottom of the lifting mechanism 2 also facilitates the transfer of tools and parts.

[0040] The height of the platform can be adjusted to meet the needs of different workstations, and a folding design can be added to save space. Furthermore, shock-absorbing pads can be installed on the platform surface to reduce the impact of vibration on personnel comfort.

[0041] In one possible implementation, a vehicle-mounted AGV (Automated Guided Vehicle) for front and rear axle assembly includes a servo motor and a battery module inside its body 1. The battery module provides power to the standing platform 7 and the lifting mechanism 2. The servo motor controls the movement and direction adjustment of the AGV, while the battery module provides the necessary power for the operation of the standing platform 7 and the lifting mechanism 2. By rationally configuring the battery capacity and servo motor power, stable operation of the equipment during the assembly process is ensured. The battery module configuration improves the equipment's endurance, making it suitable for long-term continuous operation. The application of the servo motor gives the AGV flexible mobility, allowing it to move freely between different assembly sites.

[0042] The battery module can use rechargeable lithium batteries or supercapacitors to improve energy density, and the servo motor can also be selected with a higher power model according to the AGV's load requirements. In addition, a backup power module can be added to extend the continuous working time.

[0043] In one possible implementation, the scissor lift device 22 of the lifting mechanism 2 in an AGV with integrated front and rear axles is hydraulically driven. The hydraulic drive provides power via a hydraulic pump, pushing the lifting rod 221 of the scissor lift device 22 to achieve smooth lifting and lowering movements. The hydraulic system can control the lifting speed and height by adjusting the hydraulic flow and pressure. The hydraulic drive system provides powerful performance and precise lifting control, making it suitable for scenarios requiring high loads. Furthermore, the hydraulic system operates with low noise, contributing to a better working environment.

[0044] The drive system can be either electric or pneumatic to suit different scenarios. For example, electric drive is suitable for light-load applications, while pneumatic drive can be used in explosion-proof environments.

[0045] In one possible implementation, the lifting platform 23 atop the scissor lift device 22 in an AGV for assembling front and rear axles of an automobile is provided with an anti-slip coating. The anti-slip coating increases the surface friction of the lifting platform 23, ensuring that components will not shift or fall due to slippage during lifting. The application of the anti-slip coating improves the safety and practicality of the lifting platform 23, especially preventing component slippage during assembly processes requiring precise alignment.

[0046] Anti-slip coatings can be made of various materials, such as rubber coatings or granular anti-slip layers, to meet different operational needs. Furthermore, the thickness and coverage area of ​​the coating can be adjusted according to the usage scenario.

[0047] Work Process: The AGV moves to the corresponding workstations for the front and rear axles of the vehicle, ensuring precise positioning and alignment of the lifting mechanism 2 with the assembly positions of the front and rear axles. Operators then lift the front and rear axles onto the tooling platform 23 on the AGV's lifting mechanism 2. The axles are secured using lifting rings 5 ​​and fixing structures (front axle fixing structure 3, rear axle fixing structure 4) to ensure stability during subsequent operations. Based on the vehicle model information provided by the dispatch system, the AGV adjusts the wheelbase between the front and rear axles via the sliding lifting mechanism 2. The sliding mechanism utilizes an electric rack and pinion drive to achieve smooth sliding of the lifting mechanism, ensuring accurate wheelbase adjustment. After wheelbase adjustment, the AGV moves along a predetermined path to the vehicle assembly line position, precisely aligning with the vehicle body. Once the vehicle body reaches the designated position, the AGV's front and rear lifting mechanisms 2 begin to rise, using a scissor-type lifting device 22 to raise the front and rear axles to a height aligned with the vehicle body assembly position. Operators then operate from the standing platform 7 to precisely align and assemble the front and rear axles with the vehicle body. The platform 7 provides a safe and reliable working area, while the patterned steel plate cover 6 enhances operational safety. After assembly, the operator manually confirms that the front and rear axles are firmly assembled and meet design requirements. Once confirmed, the AGV quickly leaves the main line to avoid affecting subsequent assembly processes. The AGV automatically runs to the charging station to charge the battery modules, preparing for the next task.
