Description

Technical Field

[0001] This utility model relates to the field of AGV conveying technology, specifically a combined load-bearing AGV vehicle for material transport. Background Technology

[0002] Load-bearing AGVs (Automated Guided Vehicles) are automated vehicles that can move autonomously along preset paths or intelligent navigation systems without direct human intervention and can carry a certain weight of goods. These AGVs are typically used in factories, warehouses, distribution centers, and other places to automate material handling, improve logistics efficiency, and reduce labor costs and error rates.

[0003] In the production process, when molds are moved between production lines, combined load-bearing AGVs are generally used. However, existing combined load-bearing AGVs lack a dedicated positioning structure for molds, which can cause molds to shift or tilt during transport. This makes it impossible to guarantee their accurate transfer and stable placement between production lines, which increases the time and labor costs for adjustment and calibration. It may also affect the flexibility and response speed of the entire production process, thereby reducing production efficiency.

[0004] To address this issue, we propose a combined load-bearing AGV vehicle for material transport. Utility Model Content

[0030] To make the technical means, creative features, and achieved objectives and effects of this utility model readily understandable, the present utility model will be further described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] To address the shortcomings of existing technologies, such as Figure 1 - Figure 7 As shown, this utility model provides a combined load-bearing AGV vehicle for material transportation. The AGV vehicle is used for storing materials and conveying molds. It includes: an AGV body 2 and a load-bearing box 1 installed on the AGV body 2. The load-bearing box 1 has a partition 3 arranged in the vertical direction inside. A mounting frame 4 is arranged on one side of the partition 3. Two transport mechanisms 5 for storing and conveying materials are respectively arranged on the mounting frame 4. A through groove 11 adapted to the transport mechanism 5 is opened on one side of the load-bearing box 1 to allow the mold 8 to enter and exit.

[0032] The transport mechanism 5 includes a carrying pallet 51, a drive assembly 6, and a pushing assembly 7. The carrying pallet 51 is mounted on the mounting frame 4 via the drive assembly 6. The drive assembly 6 drives the carrying pallet 51 to slide on the mounting frame 4. Two guide parts are provided on the inner walls of opposite sides of the carrying pallet 51, which are used to guide the upper and lower molds of the mold 8, respectively. Two cylinders 54 are respectively provided on the upper side of the carrying pallet 51. The output end of the cylinders 54 is fixedly connected to a wedge block 55. The two wedge blocks 55 are used to limit the upper and lower molds of the mold 8, respectively. The upper and lower molds of the mold 8 are provided with limiting grooves 81 that are adapted to the wedge blocks 55. A pushing assembly 7 for pushing the mold 8 is provided on the upper side of the carrying pallet 51.

[0033] It should be noted that when the mold 8 is loaded onto the carrier pallet 51, the cylinder 54 is activated, pushing the inclined block 55 to limit the mold 8. The cooperation between the inclined block 55 and the limiting groove 81 can effectively prevent the mold 8 from shifting horizontally during transportation, ensuring the stability of the mold 8 throughout the transportation process.

[0034] Specifically, the guide part includes a guide groove 52 and a plurality of guide wheels 53 arranged in a horizontal array. The guide wheels 53 are all rotatably connected to the inner side wall of the support tray 51. The upper mold bottom side of the mold 8 is provided with a sliding groove 82 that is adapted to the guide wheels 53. The guide groove 52 is opened on the inner wall of the support component and is located above the guide wheels 53. The guide groove 52 linearly contracts from the outside to the inside.

[0035] It should be noted that the guide wheel 53 cooperates with the guide groove 52 of the mold 8 to ensure that the mold 8 can move smoothly along the predetermined path during loading and unloading. When the mold 8 enters the carrying tray 51, the tapered shape of the guide groove 52 will gradually guide the mold 8 to the center position to achieve automatic centering, thereby improving the loading and unloading accuracy and reducing the operation error caused by the offset of the mold 8.

[0036] Specifically, the drive assembly 6 includes a horizontal guide rail 61 and two linear slide rails 64. The horizontal guide rail 61 is mounted on the mounting bracket 4, and a horizontal slider 62 is mounted on the horizontal guide rail 61. A drive motor 63 for driving the horizontal slider 62 to slide on the horizontal guide rail 61 is mounted on one side of the horizontal guide rail 61. The upper end of the horizontal slider 62 is fixedly connected to the bottom end of the support tray 51. The two linear slide rails 64 are both mounted on the mounting bracket 4 and are located on both sides of the horizontal guide rail 61. At least one linear slide rail slider 65 is slidably mounted on the linear slide rail 64, and the upper end of the linear slide rail slider 65 is fixedly connected to the bottom end of the support tray 51.

[0037] Specifically, the pushing assembly 7 includes a linear guide rail 71, which is mounted on the support tray 51. A guide rail slider 72 is slidably mounted on the linear guide rail 71. A servo motor 73 is mounted on one side of the linear guide rail 71 to drive the guide rail slider 72 to slide on the linear guide rail 71. A first electromagnet 74 is fixedly connected to the end of the guide rail slider 72. A connecting rod 75 is mounted on the upper end of the guide rail slider 72. A second electromagnet 76 is fixed to one end of the connecting rod 75. The first electromagnet 74 and the second electromagnet 76 are used to push the lower mold and the upper mold of the mold 8, respectively.

[0038] It should be noted that when the mold 8 needs to be unloaded, the drive motor 63 drives the horizontal slider 62 and the horizontal guide rail 61 to slide upwards, thereby moving the support tray 51 on the mounting frame 4. The first electromagnet 74 and the second electromagnet 76 are in a de-energized state. The servo motor 73 drives the guide rail slider 72 to move on the linear guide rail 71, causing the first electromagnet 74 and the second electromagnet 76 to move. At this time, the cylinder 54 retracts, the inclined block 55 does not limit the mold 8, and the first electromagnet 74 and the second electromagnet 76 push one side of the mold 8. After the mold 8 is removed from the support tray 51 to complete the unloading, the guide rail slider 72 is reset. When it is necessary to receive molds 8 from other production lines, the drive motor 63 is started, thereby driving the support tray 51 to move on the mounting frame 4. The guide grooves 52 and guide wheels 53 on both sides of the support tray 51 of the mold 8 slide into the support tray 51. At this time, the first electromagnet 74 and the second electromagnet 76 are energized to attract the mold 8. The cylinder 54 is started, thereby driving the inclined block 55 to be inserted into the limiting groove 81 to limit the mold 8, so as to complete the loading of the mold 8.

[0039] Specifically, a position sensor 9 is provided on the outer wall of the carrying tray 51. The position sensor 9 is set in a direction parallel to the direction of the linear guide rail 71. The position sensor 9 is used to monitor the position of the carrying tray 51 in real time. The position sensor 9 is connected to a controller, which is used to control the operation of the servo motor 73.

[0040] Specifically, the AGV vehicle body 2 includes a vehicle body frame 21, and drive wheels 22 are provided on both opposite sides of the vehicle body frame 21. A control mechanism for driving the two drive wheels 22 is provided inside the vehicle body frame 21. The control mechanism includes a motor, a reducer, an encoder and a control system, which is responsible for precisely controlling the movement of the drive wheels 22 to ensure that the AGV vehicle travels along a predetermined path.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
