Description

Technical Field

[0001] This utility model relates to the field of material tank transfer technology, specifically to a large material tank handling and docking device. Background Technology

[0002] Automated Guided Vehicles (AGVs) are industrial vehicles that load goods automatically or manually, travel automatically along a set route or tow a cargo trolley to a designated location, and then unload the goods automatically or manually. Currently, the main types include forklift-type AGVs, towing AGVs, backpack AGVs, roller AGVs, and low-profile lifting AGVs. In silicon particle production workshops, material transfer is done through turnover tanks. However, conventional AGVs cannot handle the transfer of turnover tanks or effectively dock with the receiving station. Therefore, a large-scale tank handling and docking device is needed to transport empty tanks to the receiving station for material retrieval. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a large material tank handling and docking device, which can automatically pick up and transfer large material tanks with a volume of 15 cubic meters in the production workshop, thereby reducing the labor intensity of workers, reducing staffing, and improving production efficiency.

[0004] Specifically, this utility model is implemented as follows:

[0005] A large material tank handling and docking device includes:

[0006] An AGV is equipped with two sets of symmetrically arranged forklift lifting components. The two sets of symmetrically arranged forklift lifting components are configured to move closer to each other / away from each other and to lift and move vertically; used to support and lift the material tank.

[0007] The docking unit, located at the material receiving station, includes:

[0008] The top docking assembly is mounted above the receiving station and is used to dock with the top receiving port of the material tank;

[0009] Bottom docking component is used to position the AGV.

[0010] Furthermore, the AGV has a C-shaped body, and the two sets of extension fork lifting assemblies are respectively mounted on its two outriggers. Each extension fork lifting assembly includes:

[0011] The lifting arm is mounted on the support arm and configured to move in the vertical direction;

[0012] The telescopic rod is horizontally mounted on the lifting arm and is inserted into the insertion hole in the base of the material tank when the material tank is being moved.

[0013] Furthermore, the bottom of the support arm is provided with a mounting bracket, and the mounting bracket is provided with a lifting drive component, which is connected to the lifting arm and used to drive the lifting arm to rise and fall.

[0014] Furthermore, the mounting bracket is provided with a U-shaped plate, and a guide post is provided between the U-shaped plate and the mounting bracket. A lifting slider is slidably connected to the guide post, and the lifting slider is fixedly connected to the lifting arm.

[0015] Furthermore, the top docking assembly includes:

[0016] First slide rail;

[0017] The second slide rail is slidably connected to the first slide rail and is arranged perpendicular to the second slide rail;

[0018] Move the slider so that it slides onto the second slide rail;

[0019] A telescopic tube is provided on the movable slider and configured to move in the vertical direction. Its bottom is provided with a docking bowl that connects with the material receiving port at the top of the material tank.

[0020] Furthermore, the top docking assembly also includes a vision camera for acquiring an image of the material receiving port at the top of the tank.

[0021] Furthermore, the bottom docking components include:

[0022] The positioning block is located on the bottom surface of the receiving station and is used for positioning the AGV drive wheels.

[0023] The positioning magnetic strip is installed on the bottom surface of the receiving station, and the magnetic sensor on the AGV is positioned by the positioning magnetic strip.

[0024] The working principle of this utility model:

[0025] The AGV moves to the empty material tank, inserts its telescopic rod into the socket on the tank base, and then the lifting drive unit drives the lifting arm to rise, lifting the empty material tank. The AGV then moves the empty material tank to the receiving station. When the AGV arrives at the receiving station, it is initially positioned by a positioning block, and then the magnetic sensors on the bottom of the left and right sides of the vehicle body detect the magnetic strips to confirm its position. After the AGV is in place, the vision camera detects the position of the receiving port on the top of the material tank. Then, the top docking assembly moves to perform a high-precision docking between the docking bowl and the receiving port on the top of the material tank. After docking, the material is discharged from the hopper pipe connected to the docking bowl, sending the material into the material tank. After feeding is completed, the automatic docking assembly retracts, and the AGV transfers the full material tank to the next process.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] (1) The large material tank handling and docking device provided by this utility model can realize automatic handling and automatic material receiving of the material tank, which can reduce the labor intensity of workers and improve production efficiency.

[0028] (2) The AGV adopts a fork structure and then inserts the telescopic rod into the socket of the tank base to realize the connection of the tank fish AGV, which can ensure the stability and safety of the tank during transportation.

[0029] (3) When docking the material tank, multi-level positioning docking is carried out. First, the position and attitude of the AGV are adjusted by positioning blocks and magnetic strips, and then the receiving port is positioned by vision camera, so as to achieve precise docking of docking bowl and receiving port.

Detailed Implementation

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0041] Example 1

[0042] like Figure 1-2 As shown, this embodiment discloses a large material tank handling and docking device, including: AGV1 and docking unit set on the material handling station of the production vehicle. The AGV1 includes: C-shaped body 11, four sets of drive wheels 121 and two sets of symmetrically arranged extension fork lifting components. The upper part of the body 11 is equipped with an electronic control system laser navigation 15. The four sets of drive wheels 121 are respectively installed on the two support arms 12 of the C-shaped body 11. The four sets of drive wheels 121 are all driven by independent drive motors and steering motors, which can realize omnidirectional movement.

[0043] like Figure 4 As shown, the telescopic lifting assembly is mounted on the support arm 12 and includes a lifting arm 13 and a telescopic rod 14. The lifting arm 13 is located inside the support arm 12. A mounting bracket 122 is provided at the bottom of the support arm 12. The mounting bracket 122 is equipped with a lifting drive component 132 (hydraulic cylinder), a U-shaped plate 131, and two guide posts 133. The drive end of the lifting drive component 132 is connected to the lifting arm 13 through a connecting plate to drive the lifting arm 13 to rise and fall. The guide posts 133 are located between the U-shaped plate 131 and the mounting bracket 122. A lifting slider 134 is slidably connected to the guide post 133. The lifting slider 134 is fixedly connected to the lifting arm 13. When the lifting drive component 132 drives the lifting arm 13 to rise, the lifting slider 134 moves upward along the guide post 133.

[0044] Telescopic rods 14 are horizontally mounted on the lifting arm 13, with one telescopic rod 14 at each end of the lifting arm 13. Each telescopic rod 14 is driven by an independent telescopic drive component 141 (hydraulic cylinder). The positions of the four telescopic rods 14 correspond to the positions of the four insertion holes 42 on the base of the material tank 4. Figure 5-6 As shown, AGV1 moves to the empty tank 4, inserts the telescopic rod 14 into the socket 42 of the base of the tank 4, and then the lifting drive 132 drives the lifting arm 13 to rise, thereby lifting the empty tank 4.

[0045] The docking unit includes: top docking component 2 and bottom docking component 3, such as Figure 7As shown, the top docking assembly 3 is mounted above the receiving station and is used to dock with the top receiving port 41 of the material tank 4. The top docking assembly 2 includes: a first slide rail 22, a second slide rail 23, a movable slider 24, a docking component, and a vision camera 21. The vision camera 21 is used to detect the position of the top receiving port 41 of the material tank 4. There are two first slide rails 22. The second slide rail 23 is perpendicular to the two first slide rails 22 and its two ends are slidably connected to the two first slide rails 22 respectively. The movable slider 24 is set on the second slide rail 23. The docking component is set on the movable slider 24. The movement of the docking component on the X and Y axes can be realized through the first slide rail 22, the second slide rail 23, and the movable slider 24.

[0046] The docking component consists of an electric cylinder 27, a telescopic tube 26, and a docking bowl 25. The electric cylinder 27 is fixed to the movable slider 24. The telescopic tube 26 is connected to the electric cylinder 27 and is driven to extend and retract by the electric cylinder 27. The docking bowl 25 is located at the bottom end of the telescopic tube 26 and is driven to move vertically by the electric cylinder 27. Therefore, the docking bowl 25 can move along the X, Y, and Z axes, facilitating docking with the material inlet 41 at the top of the material tank 4. The docking bowl 25 is connected to the silo pipeline, through which materials are delivered to the docking bowl 25 and ultimately enter the material tank 4. The inner surface of the docking component is coated with polyurethane, resulting in a smooth, elastic, and tight seal at the joint.

[0047] like Figure 8 As shown, the bottom docking assembly 3 includes two positioning blocks 31 and a positioning magnetic strip 32. The positioning blocks 31 are L-shaped to position the drive wheel 121. The magnetic sensor at the bottom of the AGV1 is positioned by the positioning magnetic strip 32. The AGV is positioned by the bottom positioning blocks 31 and the positioning magnetic strip 32. The AGV can be adjusted in position and attitude so that the top docking assembly can be docked with the receiving port 41 at the top of the material tank 4 with high precision.
