Description
Technical Field
[0001] This invention belongs to the field of wind power blade production technology, specifically relating to a wind power blade production assembly logistics system and its logistics method. Background Technology
[0002] Wind power generation is a clean new energy source, and the blade is the most basic and critical component of the wind turbine. Its good design, reliable quality and superior performance are the decisive factors to ensure the normal and stable operation of the unit. Manufacturing a blade requires the use of many materials, such as silicone, glass fiber polyester and hardener, which are formed in the blade mold through a complex process.
[0003] Based on the above, the existing assembly line molds are located at a height of more than 2 meters in the air, and each piece requires a large amount of manufacturing materials. Traditional production uses manual labor and overhead cranes for handling, which is labor-intensive, time-consuming, and inefficient. Therefore, in view of this, we study and improve the existing structure to provide a wind turbine blade production assembly logistics system and logistics method, in order to achieve a more practical purpose. Summary of the Invention
[0004] To address the problems existing in the prior art, the present invention aims to provide a logistics system and method for the production and assembly of wind turbine blades. The present invention sets up an efficient blade production and assembly logistics line that can automatically load and recycle material boxes, avoiding frequent back-and-forth transportation of materials between the warehouse and the work site by workers and cranes, thereby improving production and assembly efficiency. Furthermore, two sets of stabilizing components work together to apply horizontal forces to the material boxes during the loading and recycling processes, making them more stably contact or separate from the conveyor frame, thus improving the stability of material transportation.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A wind turbine blade production and assembly logistics system includes a conveyor frame, a workbench on one side of the conveyor frame, and a loading rack and a unloading rack fixedly connected to both ends of the other side of the conveyor frame, a support frame at the bottom of the loading rack and the unloading rack, a guide rail passing through the bottom of the support frame, a set of steps fixedly connected to the center of the other side of the conveyor frame, and stabilizing mechanisms at both ends of the workbench. A pair of electric slide rails are fixedly connected to the top of the support frame. The same adjusting slider is centrally mounted on the opposite surfaces of the two electric slide rails. An air pump is fixedly connected to the bottom surface of the adjusting slider. A mechanical gripper is fixedly connected to the output end of the air pump. An AGV trolley is slidably connected to the top surface of the guide rail. A material frame is provided on the top surface of the AGV trolley. The stabilizing mechanism includes a drive motor, the output end of which is fixedly connected to a lead screw, a ball bearing slider is sleeved on the outside of the lead screw, and a push plate is fixedly connected to the bottom surface of the ball bearing slider.
[0006] A further improvement of the present invention is that the workbench is L-shaped, the vertical position of the workbench is fixedly connected to one side of the conveyor frame, and the horizontal position of the workbench is directly above the conveyor frame.
[0007] A further improvement of the present invention is that the upper and lower ends of the loading rack and the unloading rack are both horizontally arranged, and the middle parts of the loading rack and the unloading rack are both inclined.
[0008] A further improvement of the present invention is that the adjusting slider is slidably connected to the support frame.
[0009] A further improvement of the present invention is that the two mechanical grippers are located at the same horizontal position as the loading rack and the unloading rack, respectively.
[0010] A further improvement of the present invention is that gripping grooves are provided on both sides of the material frame, and the material frame is adapted to the mechanical gripper.
[0011] A further improvement of the present invention is that the two drive motors are fixedly connected to both ends of the worktable, and the lead screw is movably connected to the worktable.
[0012] A further improvement of the present invention is that a guide block is fixedly connected to the top surface of the ball slider, and the guide block is slidably connected to the worktable.
[0013] A further improvement of the present invention is that the bottom surfaces of the two push plates are flush with the upper ends of the loading rack and the unloading rack, respectively.
[0014] A logistics method for a wind turbine blade production and assembly logistics system, comprising: Material boxes filled with materials are transported to one side of the loading rack by an AGV trolley. An air pump, in conjunction with a mechanical gripper, grabs the material box and places it at the lower end of the loading rack. The loading rack then transports the material box. When the material box moves to the upper end of the loading rack, the drive motor at the front of the workbench is started, which drives the lead screw to rotate. The lead screw, in conjunction with the ball bearing slider, pushes the push plate to push the material box at the top of the loading rack into the conveyor frame, where it moves along the conveyor frame. When it moves to the corresponding workstation, the assembly personnel take out the parts inside and put the empty material box back into the conveyor. When it moves to the rear end of the conveyor, the corresponding push plate pushes the empty material box to the top of the unloading rack, so that it moves downward. The idle AGV trolley continues to move along the guide rail to one side of the unloading rack. Then, with the help of the corresponding air pump and mechanical gripper, the material frame at the bottom of the unloading rack is grabbed and placed on the top of the idle AGV trolley, completing the material frame recycling work. Finally, the assembly personnel use the platform to assemble the blade mold on the workbench.
[0015] Compared with the prior art, the present invention has at least the following beneficial technical effects: This invention utilizes guide rails in conjunction with AGV trolleys to transport material frames, which are then gripped by mechanical grippers. Simultaneously, a loading rack loads the material frames, and a unloading rack recycles them. Compared to existing technologies, this invention establishes a highly efficient blade production and assembly logistics line that automates the loading and recycling of material frames, avoiding frequent trips between warehouses and work sites for workers and cranes, thus improving production and assembly efficiency.
[0016] This invention features a stabilizing mechanism. A lead screw rotates, and in conjunction with a ball bearing slider, a pusher plate moves the material frame horizontally, allowing it to be smoothly adjusted horizontally from the conveyor frame. Compared to existing technologies, this invention uses two sets of stabilizing components that work together to apply a horizontal force to the material frame during the feeding and recycling processes, making it more stable in contact with or separate from the conveyor frame, thus improving the stability of material transportation.

[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0028] Example 1 Please see Figure 1-6 This invention provides a logistics system for the production and assembly of wind turbine blades, including a conveyor frame 1. A workbench 2 is provided on one side of the conveyor frame 1, and a loading frame 3 and a unloading frame 4 are fixedly connected to both ends of the other side of the conveyor frame 1. A support frame 5 is provided at the bottom of both the loading frame 3 and the unloading frame 4, and a guide rail 6 is provided through the bottom of the support frame 5. A set of steps 7 is fixedly connected to the center of the other side of the conveyor frame 1, and stabilizing mechanisms 8 are provided at both ends of the workbench 2. A pair of electric slide rails 9 are fixedly connected to the top of the support frame 5, and a centrally located mounting bracket is provided on the opposite side of the two electric slide rails 9. The same adjusting slider 10 has an air pump 11 fixedly connected to its bottom surface, and a mechanical gripper 12 fixedly connected to the output end of the air pump 11. An AGV trolley 13 is slidably connected to the top surface of the guide rail 6, and a material frame 14 is set on the top surface of the AGV trolley 13. The stabilizing mechanism 8 includes a drive motor 15, a lead screw 16 fixedly connected to the output end of the drive motor 15, a ball bearing slider 17 sleeved on the outside of the lead screw 16, and a push plate 18 fixedly connected to the bottom surface of the ball bearing slider 17. The stabilizing mechanism 8 is provided to ensure the stability of the material frame 14 during the up and down process.
[0029] See Figure 1The workbench 2 is L-shaped. The vertical position of the workbench 2 is fixedly connected to one side of the conveyor frame 1, and the horizontal position of the workbench 2 is directly above the conveyor frame 1. The assembly personnel use the step platform 7 to assemble the blade mold on the workbench 2.
[0030] See Figure 2 The upper and lower ends of the feeding rack 3 and the unloading rack 4 are both horizontally set, and the middle of the feeding rack 3 and the unloading rack 4 are both inclined. The feeding rack 3 is used to feed the material frame 14, and the unloading rack 4 is used to recycle the material frame 14.
[0031] See Figure 5 The adjusting slider 10 is slidably connected to the support frame 5. Two mechanical grippers 12 are positioned at the same horizontal level as the loading rack 3 and unloading rack 4, respectively. Material boxes 14 filled with material are transported to one side of the loading rack 3 via an AGV trolley 13. An air pump 11, in conjunction with the mechanical grippers 12, grips the material box 14 and places it at the lower end of the loading rack 3. This invention, through the cooperation of the mechanical grippers 12 and the air pump 11, enables the system to automatically grip and place the material box 14, reducing reliance on manual operation and improving the automation level of the production line. The introduction of the AGV trolley 13 further enhances the system's automation capabilities, realizing automatic material conveying and positioning. The mechanical grippers and air pump are typically driven by a sophisticated control system, ensuring accurate gripping and placement of the material box and reducing operational errors. The AGV trolley's navigation system also ensures that the material is accurately conveyed to the designated location, further improving the system's accuracy. The sliding connection design between the adjusting slider 10 and the support frame 5 gives the system a certain degree of flexibility, allowing the position and angle of the mechanical grippers to be adjusted as needed to accommodate material boxes of different sizes and shapes. AGVs can also flexibly adjust their travel paths and speeds as needed to adapt to different production requirements.
[0032] See Figure 5The material frame 14 has gripping slots on both sides, and the material frame 14 is compatible with the mechanical gripper 12. The AGV trolley 13 then moves along the guide rail 6 to one side of the unloading rack 4. The corresponding air pump 11, in conjunction with the mechanical gripper 12, grips the material frame 14 at the lower end of the unloading rack 4 and places it on the top of the empty AGV trolley 13, completing the material frame 14 recycling process. The gripping slots on both sides of the material frame 14 are perfectly matched with the mechanical gripper 12, ensuring the accuracy and stability of the gripping action. This design reduces errors during the gripping process and improves work efficiency. The entire process is highly automated. From the AGV trolley 13 moving along the guide rail 6 to the designated position, to the air pump 11 and mechanical gripper 12 gripping the material frame 14, and then placing it on the top of the empty AGV trolley 13, all are completed automatically by the equipment, reducing manual intervention and improving the automation level of the production line. By using AGV carts 13 for transportation, production space can be utilized more effectively, reducing material accumulation and waiting time on the production line, thereby improving the overall efficiency of the production line.
[0033] See Figure 6 Two drive motors 15 are fixedly connected to both ends of the worktable 2, and the lead screw 16 is movably connected to the worktable 2, and the lead screw 16 is driven to rotate by the drive motors 15.
[0034] See Figure 6 A guide block is fixedly connected to the top surface of the ball slider 17, and the guide block is slidably connected to the worktable 2. The guide block ensures the movement stability of the ball slider 17.
[0035] See Figure 6 The bottom surfaces of the two push plates 18 are flush with the upper ends of the loading rack 3 and the unloading rack 4, respectively. The push plates 18 push the material frame 14 at the top of the loading rack 3 into the conveyor rack 1 and move on the conveyor rack 1. When it moves to the corresponding work station, the assembly personnel take out the parts inside and perform blade assembly work. At the same time, the empty material frame 14 is put back into the conveyor rack 1. When it moves to the rear end of the conveyor rack 1, the corresponding push plate 18 pushes the empty material frame 14 to the top of the unloading rack 4.
[0036] This invention automatically pushes the material frame 14 along the conveyor frame 1 using a pusher plate 18, reducing the need for manual handling and improving production efficiency. This automated operation helps reduce labor costs and makes the entire production process smoother. The design of the loading rack 3, conveyor frame 1, and unloading rack 4 allows the material frame to move orderly between different positions without requiring additional storage space. This layout maximizes the use of existing space, making the production site cleaner and more efficient. The material frame starts from the loading rack, passes through the conveyor frame for parts assembly, and finally ends at the unloading rack, making the entire process clear and straightforward. This clear process helps reduce errors and confusion, improving product quality. As the material frame moves along the conveyor frame, when it reaches the corresponding workstation, assembly personnel can easily retrieve the parts for assembly. This design allows assembly personnel to more easily access and manipulate materials, improving work efficiency. By automating the movement of the material frame, the waiting time between different workstations is reduced. This reduction in waiting time helps improve overall production efficiency and makes the production process more efficient.
[0037] Example 2 This invention provides a logistics method for a wind turbine blade production and assembly logistics system, comprising: Material boxes 14 containing materials are transported to one side of the loading rack 3 by AGV trolley 13. An air pump 11, in conjunction with a mechanical gripper 12, grabs the material box 14 and places it at the lower end of the loading rack 3. The loading rack 3 then transports the material box 14. When the material box 14 moves to the upper end of the loading rack 3, the drive motor 15 at the front of the workbench 2 is activated, driving the lead screw 16 to rotate. The lead screw 16, in conjunction with the ball bearing slider 17, causes the push plate 18 to push the material box 14 at the top of the loading rack 3 into the conveyor frame 1. The material box 14 then moves along the conveyor frame 1. When it reaches the corresponding workstation, the assembly personnel remove the parts from inside. Simultaneously, the empty material frame 14 is placed back into the conveyor frame 1. When it moves to the rear end of the conveyor frame 1, the corresponding push plate 18 pushes the empty material frame 14 to the top of the unloading frame 4, causing it to move downwards. At the same time, the empty AGV trolley 13 continues to move along the guide rail 6 to one side of the unloading frame 4. Then, the corresponding air pump 11, in conjunction with the mechanical gripper 12, grabs the material frame 14 at the bottom of the unloading frame 4 and places it on the top surface of the empty AGV trolley 13, completing the recycling of the material frame 14. Finally, the assembly personnel use the platform 7 to assemble the blade mold on the workbench 2.
[0038] In summary, the entire process of this invention, from material conveying, gripping, placing, pushing to recycling, achieves a high degree of automation, reducing manual intervention and improving work efficiency. Material frames are transported to the loading rack by AGV carts, and then loaded, conveyed, and unloaded using mechanical grippers and pushers. The entire process is rationally designed with tight connections between each link, ensuring smooth operation. The use of mechanical grippers and pushers enables precise gripping and positioning of the material frames, ensuring accuracy and stability during conveying and assembly. The automated equipment allows for centralized management and monitoring through a control system, facilitating timely problem detection and resolution, and improving management efficiency and accuracy. The use of automated equipment reduces manual operation and the risk of injury; furthermore, the design and material selection of the equipment take safety into account, ensuring the safety of the entire process.
