Description

Technical Field

[0001] This utility model relates to the field of automated guided vehicles, specifically an AGV vehicle for transporting mother baskets. Background Technology

[0002] AGVs, or Automated Guided Vehicles, are battery-powered, driverless transport vehicles that navigate along pre-set paths using magnetic strips, tracks, lasers, or QR codes. They are equipped with safety protection and transfer devices. AGVs can be categorized in various ways based on their function, operating method, and navigation method. Functionally, they cover transport, assembly, and heavy-duty applications; navigationally, they can be divided into magnetic navigation AGVs and laser navigation AGVs.

[0003] Existing AGVs with material handling functions have simple frames with crossbeams on top for suspending materials or platforms for placing materials. These crossbeams or platforms can only transport materials via the AGV. When the AGV reaches the loading / unloading point, manual operation is required, which is inefficient. This manual handling method is not only time-consuming but also prone to low handling efficiency, especially when the material volume is large or the handling distance is long, the efficiency of manual handling will be further reduced. At the same time, because manual intervention is required for material handling, the production process may be interrupted due to untimely or inaccurate manual operation, affecting the continuity and stability of production. Therefore, a special automated transport AGV for mother baskets is needed to solve the above problems. Utility Model Content

[0004] Accordingly, this utility model proposes an AGV for transporting mother baskets, which can automatically guide the mother basket to its destination and unload the basket itself after a robotic arm hangs the crossbars onto the AGV.

[0017] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0018] The embodiments of this utility model will be described below based on its overall structure.

[0019] This utility model provides an AGV vehicle for transporting mother baskets, such as... Figure 1-7 The system includes a vehicle frame 1, a navigation mechanism 3, a power mechanism 4, a base 6, a transmission mechanism 2, and a walking mechanism 5. In this solution, the above mechanisms are connected sequentially from bottom to top: the walking mechanism 5, the base 6, and the vehicle frame 1. The vehicle frame 1 is fixedly installed on the base 6 for mounting the transmission mechanism 2. The transmission mechanism 2 is fixed to the top of the vehicle frame 1 for transporting the mother basket. The navigation mechanism 3 is fixedly connected to one side of the transmission mechanism 2 for directional navigation of the entire vehicle. The walking mechanism 5 is fixed to the bottom of the base 6 to control the movement of the entire vehicle. The power mechanism 4 is located on the outer surface of the base 6 to provide power for the operation of the vehicle.

[0020] In this embodiment, as Figure 1-2 The vehicle frame 1 includes a top plate 10, a beam 11 and a support column 12. The beam 11 includes a bottom beam 111 and a side beam 112. The vehicle frame 1 serves as the main body of the AGV vehicle, is fixed on the base 6 and connected to the overall vehicle body, and also serves as a skeleton to install the mounting mechanism and the transmission mechanism 2.

[0021] Specifically, the support columns 12 are a pair, fixed diagonally on the top plane of the base 6 to support the top plate 10. The bottom beam 111 consists of four columns connected in a rectangle and fixedly installed on the surface of the top plate 10. The side beams 112 are a pair of U-shaped combined columns that are fixed to the short sides of the bottom beams 111 respectively. The bottom beams 111 and the side beams 112 are fixedly connected together to form the vehicle frame.

[0022] In this embodiment, the automatic transport of the mother basket mainly relies on the transmission mechanism 2, such as... Figure 3-4 The transmission mechanism 2 includes a mounting box 20 and a transmission component 22. One end of the mounting box 20 is fixed to the transmission component 22, and the other end is equipped with the navigation mechanism 3. The transmission mechanism 2 also includes a motor 21 disposed inside the mounting box 20. The output end of the motor 21 is connected to the transmission component 22. The transmission component 22 includes a synchronous belt 220, a drive wheel 221, a driven wheel 222, and a transmission shaft 223.

[0023] Specifically, the driving pulley 221 and the driven pulley 222 are a pair. The pair of driving pulleys 221 are arranged opposite each other and fixedly connected axially by the transmission shaft 223. The two driven pulleys 222 are respectively arranged tangentially to the two driving pulleys 221 at a certain distance from the driving pulleys 221. The synchronous belt 220 is one loop, covering the driven pulleys 222 and the driving pulleys 221. One of the driving pulleys 221 is connected to the motor 21 on the side away from the transmission shaft 223. The output shaft of the motor 21 rotates, driving one of the driving pulleys 221 to further drive it through the synchronous belt 220. The driven wheel 222 of the transmission causes the synchronous belt 220 on it to rotate. At the same time, the rotation of the driving wheel 221 drives the transmission shaft 223 to rotate, thereby driving the other driving wheel 221 at the other end of the transmission shaft 223 to rotate, so as to realize the synchronous transmission of the two transmission components 22 on both sides, thereby transferring and unloading the mother basket placed on it. Compared with the existing fixed mounting structure, the present invention uses the synchronous belt 220 and related components to automatically transfer and unload the mother basket after the AGV arrives at the unloading point, without the need for manual unloading.

[0024] Furthermore, the transmission assembly 22 also includes a pair of support members 225, one side of which is fixed to the top transverse axis of the side beam 112 respectively. The support members 225 are placed inside the synchronous belt 220 and are basically in contact with the synchronous belt 220. There are also two sets of mounting plates 224 that are symmetrically fixed to both sides of the drive pulley 221 through the support members 225, so as to support the synchronous belt 220 and prevent the synchronous belt 220 from breaking after long-term use.

[0025] In this embodiment, the automatic navigation of the AGV vehicle mainly relies on the navigation mechanism 3, such as... Figure 5 Specifically, the navigation mechanism 3 is a laser navigation device 30, which is fixedly installed on the mounting box 20 for directional navigation of the entire vehicle.

[0026] In this embodiment, a power mechanism 4 is also included to provide a power source for the entire device, such as... Figure 6 The power mechanism 4 includes a power socket 41 on the base 6 for charging the AGV vehicle and a power cover 42 connected to and covering the power socket 41.

[0027] In this embodiment, the AGV vehicle's drive mainly relies on the walking mechanism 5, such as... Figure 7 The walking mechanism 5 includes a base plate 50, four casters 51 with feet mounted at the four corners of the base plate 50, and a pair of drive wheels 52 mounted on the two long sides of the base plate 50. In use, the two drive wheels 52 provide greater driving force, which is suitable for when the car needs to move quickly, while the four casters 51 are lighter and more suitable for the car to turn flexibly.

[0028] In this embodiment, a control system built into the base 6 is also included. The control system has a built-in power supply and can be charged through the power socket 41. The walking mechanism 5 is electrically connected to the control mechanism to control the entire vehicle.

[0029] In a specific implementation, this design is used to transport a mother basket of materials. The mother basket is typically large in volume, contains multiple daughter baskets, and is integrally formed with a flat strip-shaped crossbar for hanging. This AGV, as a link in the automated sorting line, plays a transporting role. At the material to be sorted inlet, when the robotic arm places the mother basket with the hanging crossbar onto the synchronous belt 220 in front of the AGV's drive shaft 223, the control system transmits a command to drive the drive wheel 52, propelling the AGV forward. During this process, the laser navigator 30 identifies and navigates the AGV along a predetermined route. During operation, the omnidirectional wheels 51 are used for vehicle steering and lifting on non-planar road sections. When the AGV carrying the mother basket arrives at the unloading point of the sorting unit, the control system starts the motor 21. The output shaft of the motor 21 rotates, driving the two-sided transmission components 22 to rotate, so that the mother basket is transported from the side near the drive shaft 223 towards the driven wheel 222 and falls to the unloading point by itself. When finished, the AGV is charged at the power socket 41. With the cooperation of this AGV, the entire sorting process of the mother basket is fully automated without manual intervention, thus improving efficiency.
