Description

Technical Field

[0001] This utility model relates to the field of AGV technology, specifically to a quick-change modular vehicle mechanism for AGVs. Background Technology

[0002] With the deepening of Industry 4.0 and intelligent manufacturing, AGVs (Automated Guided Vehicles), as core equipment of flexible logistics systems, have been widely used in warehousing and handling, automobile manufacturing, 3C electronics and other fields. Modern production scenarios have placed higher demands on the adaptability, flexibility and operating efficiency of AGVs, especially in mixed-line production modes with multiple varieties and small batches. AGVs need to quickly adapt to materials of different sizes, guide rails and working conditions, which makes quick-change and modularization the core development trend of AGV carrier mechanisms.

[0003] Existing AGV carrier mechanisms suffer from several technical pain points: First, insufficient wheelbase adjustment capability. The wheel spacing of most AGVs is fixed or requires manual disassembly and adjustment, making it difficult to quickly adapt to guide rails or work channels of different widths. This results in poor equipment versatility and time-consuming and labor-intensive switching of work scenarios. Second, unreasonable height adjustment mechanism design. Some use a single cylinder or screw drive, which has problems such as weak load-bearing stability, low adjustment accuracy, and slow response speed. It is difficult to meet the storage or conveying needs of materials of different heights, and deformation and jamming are prone to occur under heavy load conditions. Third, insufficient modularity and quick-changeability of the carrying mechanism. Most carrying components are fixed by bolts. When replacing different types of carrying modules (such as pallets and clamping components), tools are required for disassembly, which is cumbersome and seriously affects work efficiency. Utility Model Content

[0004] The present invention aims to solve the problems mentioned in the background art by providing a quick-change modular vehicle mechanism for AGVs.

[0005] The specific technical solution is as follows: A quick-change modular vehicle mechanism for AGVs includes: an AGV body, an infrared sensing module on one side of the AGV body, a support mechanism on the inner wall of the bottom of the AGV body, a height adjustment mechanism at the bottom of the support mechanism; a wheelbase adjustment mechanism and a moving mechanism at the bottom of the AGV body; a cargo-carrying mechanism on the top of the AGV body; and protective components on the surface of the AGV body.

[0006] As a preferred embodiment of this utility model, the support mechanism includes a support block, bolts, and through holes. The support block is threadedly connected to the bottom of the AGV body by bolts, and a through hole is provided on one side of the support block. In this embodiment, the combined use of the support block, bolts, and through holes can provide stable support for the height adjustment mechanism and can also limit the movement of the two sets of horizontal plates, thereby preventing the horizontal plates from colliding with each other.

[0007] In a preferred embodiment of this utility model, the height adjustment mechanism includes a hydraulic cylinder, a connecting rod, and a connecting frame. Two sets of hydraulic cylinders are rotatably mounted on both sides of the inner wall at the bottom of the support block. The telescopic ends of the hydraulic cylinders are fixedly mounted to the connecting rod. Two sets of connecting frames are rotatably mounted on both sides of the connecting rod surface. In this embodiment, the coordinated use of the hydraulic cylinders, connecting rod, and connecting frame allows the hydraulic cylinders to push and pull, causing the connecting rod to retract. This allows the connecting frame and rotating frame to lift the AGV body upwards according to the retraction of the connecting rod, thereby raising the chassis of the AGV body as needed.

[0008] In a preferred embodiment of this utility model, the wheelbase adjustment mechanism includes a forward and reverse screw and a stepper motor. The forward and reverse screw is rotatably mounted on the inner wall of the bottom of the AGV body. The forward and reverse screw is located in a through hole opened on one side of the support block and is movably connected to the support block. The stepper motor is fixedly mounted on one side of the AGV body, and the output end of the stepper motor is fixedly mounted to the forward and reverse screw. In this embodiment, the combined use of the forward and reverse screw and the stepper motor can control the distance between the two sets of cross plates, thereby achieving the effect of adjusting the width of the moving wheel axle. This allows the AGV body to adapt to tracks of different widths and enables rapid conversion during line changes.

[0009] In a preferred embodiment of this utility model, the moving mechanism includes a horizontal plate, a rotating frame, and moving wheels. Two sets of horizontal plates are provided, threadedly connected to both sides of the surfaces of forward and reverse screws. Both sides of the two sets of horizontal plates are rotatably mounted to the rotating frame. The side of the rotating frame away from the horizontal plate is rotatably mounted to the moving wheels. The bottom of the rotating frame is fixedly connected to a connecting frame. A motor for driving the moving wheels to rotate is provided on the side of the rotating frame away from the moving wheels. In this embodiment, the coordinated use of the horizontal plate, rotating frame, and moving wheels ensures that the AGV body can move normally, and also allows for slow translation based on the wheelbase adjustment mechanism, thus achieving wheelbase adjustment.

[0010] As a preferred embodiment of this utility model, the loading mechanism includes a rotating block, a cross-shaped insert rod, and a support plate. The rotating block is rotatably mounted on the top of the AGV body, the cross-shaped insert rod is movably inserted into the inner wall of the rotating block, and the top of the cross-shaped insert rod is fixedly mounted to the support plate. In this embodiment, the coordinated use of the rotating block, the cross-shaped insert rod, and the support plate enables the support plate to be quickly installed and replaced. This allows for timely replacement of the support plate to adapt to new types of goods during line changes, thus improving the compatibility of the AGV body.

[0011] As a preferred embodiment of this utility model, the protective component includes a rubber shell and a groove. The rubber shell is fixedly installed on the surface of the AGV body, and the groove is provided on the side of the rubber shell away from the AGV body. In this embodiment, the combined use of the rubber shell and the groove can provide the main protective effect for the AGV body, thereby preventing the AGV body from being bumped or scratched during use.

[0012] As a preferred embodiment of this utility model, the connecting rod is made of stainless steel. The surface of the stainless steel has a high degree of smoothness, which makes the connecting frame slide more smoothly. At the same time, the use of lubricating oil can reduce wear when the connecting frame moves. In addition, stainless steel has extremely high hardness, which can achieve the effect of driving the horizontal plate.

[0013] This utility model has the following beneficial effects: 1. The quick-change modular vehicle mechanism for AGVs provided by this utility model, through the arrangement of support blocks, bolts, through holes, hydraulic cylinders, connecting rods and connecting frames, enables the support blocks, bolts and through holes to provide stable support for the height adjustment mechanism and limit the two sets of horizontal plates, thereby preventing the horizontal plates from colliding with each other. The hydraulic cylinders, connecting rods and connecting frames work together so that the hydraulic cylinders push and pull to drive the connecting rods to retract, thereby enabling the connecting frame and rotating frame to lift the AGV body upward according to the retraction of the connecting rods, thus allowing the chassis of the AGV body to be raised as needed.

[0014] 2. The quick-change modular carrier mechanism for AGVs provided by this utility model, through the arrangement of forward and reverse screws, stepper motors, horizontal plates, rotating frames, and moving wheels, enables the cooperation of forward and reverse screws and stepper motors to control the distance between two sets of horizontal plates, thereby achieving the effect of adjusting the axle width of the moving wheels. This allows the AGV body to adapt to tracks of different widths, enabling rapid conversion during line changes. The cooperation of the horizontal plates, rotating frames, and moving wheels ensures that the AGV body can move normally, and at the same time, it can achieve slow translation by adjusting the wheelbase adjustment mechanism to realize the adjustment of the wheelbase.

The wheelbase adjustment mechanism 5 includes a forward and reverse screw 51 and a stepper motor 52. The forward and reverse screw 51 is rotatably installed on the inner wall of the bottom of the AGV body 1. The forward and reverse screw 51 is located on one side of the support block 31 with a through hole 33. Inside hole 33, forward and reverse screws 51 are movably connected to support block 31.

[0022] In summary, the quick-change modular vehicle mechanism for AGVs provided in this embodiment has the following advantages: the cooperation of the support block 31, bolt 32, and through hole 33 can provide stable support for the height adjustment mechanism 4 and limit the two sets of horizontal plates 61, thereby preventing the horizontal plates 61 from colliding with each other; the cooperation of the hydraulic cylinder 41, connecting rod 42, and connecting frame 43 can drive the connecting rod 42 to retract through the push and pull of the hydraulic cylinder 41, so that the connecting frame 43 and rotating frame 62 can lift the AGV body 1 upward according to the retraction of the connecting rod 42, thereby raising the chassis of the AGV body 1 as needed; the cooperation of the forward and reverse screws 51 and stepper motor 52 can control the distance between the two sets of horizontal plates 61, thereby achieving the effect of adjusting the axle width of the moving wheel 63, so that the AGV body 1 can adapt to tracks of different widths and achieve quick changeover during line switching. The rapid conversion, the coordinated use of the horizontal plate 61, the rotating frame 62, and the moving wheel 63 ensures that the AGV body 1 can move normally. At the same time, it can also achieve slow translation according to the adjustment of the wheelbase adjustment mechanism 5 to adjust the wheelbase. The coordinated use of the rotating block 71, the cross rod 72, and the bearing plate 73 allows the bearing plate 73 to be quickly installed and replaced. This allows the bearing plate 73 to be replaced in time to adapt to new types of goods when changing lines, improving the compatibility of the AGV body 1. The coordinated use of the rubber shell 81 and the groove 82 provides the main protection for the AGV body 1, thus preventing the AGV body 1 from being bumped or scratched during use. The stainless steel surface has a high degree of smoothness, which makes the connecting frame 43 slide more smoothly. At the same time, the use of lubricating oil reduces wear when the connecting frame 43 moves. In addition, the high hardness of stainless steel enables the horizontal plate 61 to be driven.

[0023] In use, first place the AGV body 1 on a flat surface, then place the moving wheels 63 into the guide rails, then lift the support plate 73 and align the crossbar 72 with the rotating block 71. Insert the crossbar 72 into the rotating block 71, and it is ready for use. During use, the user needs to place the goods on top of the support plate 73, and then transportation can begin. During transportation, the user can activate the hydraulic cylinder 41 to pull the connecting rods 42 on both sides to retract. When the connecting rods 42 retract, they will drive the two sets of rotating frames 62 to rotate through the connecting frame 43. When the rotating frames 62 rotate, they will continuously lift the AGV body 1 upwards, thereby raising the chassis of the AGV body 1 to facilitate obstacle avoidance or unloading. Simultaneously, when a quick line change is required, the user needs to activate the stepper motor 5. 2. This drives the forward and reverse screws 51 to rotate. The rotation of the forward and reverse screws 51 will drive the two sets of horizontal plates 61 to move axially along the stepper motor 52. When the horizontal plates 61 move, they will drive the rotating frame 62 and the moving wheel 63 to move synchronously, thereby making the axle width of the moving wheel 63 longer or narrower. Then, the user can install the AGV body 1 on the track of different widths to achieve the effect of quick line change, which improves the versatility of the AGV body 1. At the same time, when the bearing plate 73 wears out during long-term use, the user can directly remove it for replacement. This modular design can improve the working efficiency of the AGV body 1. When the AGV body 1 is bumped during use, the rubber shell 81 can also provide cushioning and protection for the AGV body 1 to prevent the goods from collapsing.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
