[0022] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the embodiments and drawings. Herein, the illustrative embodiments of the present application and the descriptions thereof are used to explain the present application, but are not used as limitations of the present application.

[0023] It should also be noted that, in order to avoid the present application being obscured by unnecessary details, only the structures and / or processing steps closely related to the solutions according to the present application are shown in the drawings, and other details not closely related to the present application are omitted.

[0024] It should be emphasized that the term "comprises / comprising" as used herein is used to indicate the presence of the stated features, elements, steps or components but does not preclude the presence or addition of one or more other features, elements, steps or components.

[0025] It should also be noted that, if not specifically stated, the term "connected" as used herein can not only mean direct connection, but also indirect connection in the presence of an intermediate.

[0026] In the following, embodiments of the present application will be described with reference to the drawings. In the drawings, the same reference signs represent the same or similar components, or the same or similar steps.

[0027] Reference Figure 1The embodiment of the present application provides a composite material winding device based on a UAV, which comprises a clamping mechanism 1, a core mold 2, a UAV 3 and a bobbin, the core mold 2 is clamped on the clamping mechanism 1, the bobbin is installed on the UAV 3, the bobbin is provided with a winding yarn 4, one end of the winding yarn 4 is fixedly connected to the core mold 2, the UAV 3 flies around the core mold 2 and is used for winding the winding yarn 4 on the core mold 2. The winding yarn 4 can be carried by the UAV, or a creel can be placed on the ground, and the yarn is wound through the UAV.

[0028] In the above embodiment, the UAV 3 carries the bobbin and controls the flight around the core mold 2, so that the automatic winding process of the composite material (the winding yarn 4) is realized. This improvement significantly improves the winding efficiency, reduces the labor cost, and ensures the consistency and stability of the winding process. The flight path of the UAV 3 can be programmed and controlled, and can be flexibly adjusted to adapt to core molds 2 of different shapes and sizes. This means that the device can be widely used in the production of various composite material products, improving the versatility and flexibility of the equipment. Precise flight control of the UAV 3 can ensure that the winding yarn 4 is uniformly and tightly wound on the core mold 2, avoiding problems such as uneven thickness and poor overlap that may be caused by traditional winding machines. This not only improves the appearance quality of the product, but also enhances the overall structural strength and performance of the composite material.

[0029] In some embodiments, at least two UAVs 3 are provided, and the at least two UAVs 3 fly around the same core mold 2. Multiple UAVs 3 can double the work efficiency when winding the same product. At the same time, the UAV is provided with a laser positioning function, which can automatically establish a spatial coordinate system based on the actual core mold position on site, without the need for secondary calibration, in order to improve the flexibility of winding. The UAV can provide multiple degrees of freedom, so the winding is not limited to conventional rotation body winding, opening winding, elbow winding and other winding modes.

[0030] In some embodiments, the UAV 3 is provided with a storage battery or the UAV 3 is connected to a power source through a wire. The UAV can use a self-powered UAV, which is more flexible, or a UAV connected with a cable for long-term operation.

[0031] In some embodiments, the core mold 2 is horizontally arranged or the core mold 2 is vertically arranged. Since the UAV can provide flexible degrees of freedom, the state of the core mold 2 can be set according to actual needs, and is not limited to horizontal and vertical arrangements, but can also be arranged obliquely.

[0032] In some embodiments, the unmanned aerial vehicle-based composite material winding device further comprises a sliding rail 5 installed on the ground, and the clamping mechanism 1 is in sliding connection with the sliding rail 5 to adapt to different lengths of the mandrel 2. The introduction of the sliding rail 5 enables the clamping mechanism 1 to move horizontally on the ground, thereby easily adapting to different lengths of the mandrel 2. This improvement breaks the original limitation of the mandrel length, enabling the winding device to be applied to the production of more types of composite products, thereby improving the universality and market competitiveness of the equipment. By adjusting the position of the clamping mechanism 1 on the sliding rail 5, the relative positional relationship between the mandrel 2 and the unmanned aerial vehicle 3 can be flexibly changed. This helps to optimize the winding path, reduce the flight distance and time of the unmanned aerial vehicle 3, and further improve the winding efficiency. At the same time, the sliding connection of the sliding rail 5 also makes it possible to realize more complex winding patterns and shapes.

[0033] Referring to Figure 2 In some embodiments, the clamping mechanism 1 is provided with at least two groups, and the at least two groups of clamping mechanisms 1 are arranged along the same horizontal axis to clamp at least two mandrels 2.

[0034] In some embodiments, the unmanned aerial vehicle-based composite material winding device further comprises a rotating drive member for driving the mandrel 2 to rotate around its own axis. The rotation of the mandrel 2 can be realized by the rotating drive member to cooperate with the unmanned aerial vehicle winding, greatly improving the winding efficiency.

[0035] In some embodiments, the rotating drive member comprises any one of a motor, a hydraulic motor, and an engine.

[0036] In some embodiments, the clamping mechanism 1 has a chuck or a center, which is used for centering the mandrel 2. When multiple products need to be produced simultaneously (whether the sizes are consistent or not), the sliding rail can be modified to increase the number of sliding rails and clamping mechanisms. The arrangement can be based on the actual site requirements. It is not limited to the same horizontal line shown in the figure.

[0037] In some embodiments, the clamping mechanism 1 is a cantilever clamping structure or a double-sided clamping structure. When winding short-diameter and light-weight products (the stiffness of the winding tool needs to be checked for strength, and compared with the fixed clamping method of double-sided clamping, the cantilever clamping method may cause larger displacement, which depends on the specific product), the cantilever clamping method can be used to clamp only one side. When clamping large-size products, both sides need to be clamped to reduce deformation and improve the accuracy of the mandrel.

[0038] The problems of the multi-station winding machine in the prior art are that: like the single-station winding machine, the multi-station winding machine also has the problem of troublesome use and maintenance; the multi-station winding machine can simultaneously wind multiple products, generally the multi-station winding machine is arranged in an up-down manner, and when the winding diameter of one product in one row interferes with the next row of products, the multiple products cannot be simultaneously wound, and there is strong limitation; the core mold bearing capacity of the multi-station winding machine is generally small, and it is not conducive to winding of large products.

[0039] The unmanned aerial vehicle-based composite material winding device in the above embodiment adopts unmanned equipment to replace the yarn feeding mode of the traditional runway-type winding machine, improves the flexibility of the winding device expansion, and if multiple unmanned aerial vehicles are used to simultaneously wind, the efficiency is multiple times that of the traditional winding device. Through the clamping mechanism that can be flexibly adjusted, winding products of any length can be made, and even if the two clamping mechanisms on the sides are slightly different in axis due to length, the unmanned aerial vehicle can compensate for the difference in freedom. Almost any shape of winding can be achieved, such as axisymmetric, conical, three-way pipe, and bent pipe.

[0040] The unmanned aerial vehicle-based composite material winding device of the embodiment has the following advantages compared with the single-station winding machine:

[0041] 1. The efficiency can be improved by expanding the unmanned aerial vehicles;

[0042] 2. Multiple products can be wound on the same track;

[0043] 3. High degree of freedom winding mode can be achieved;

[0044] 4. The core mold can be wound without rotation, and the winding is completely performed by the unmanned aerial vehicle;

[0045] The unmanned aerial vehicle-based composite material winding device of the embodiment has the following advantages compared with the multi-station winding machine: a horizontal arrangement can be used instead of the traditional vertical arrangement of the multi-station winding machine, and the arrangement is more flexible.

[0046] It should be noted that the present application is not limited to the specific configurations and processes described above and shown in the drawings. For the sake of brevity, detailed descriptions of well-known methods are omitted herein. In the above embodiments, several specific steps are described and shown as examples. However, the method process of the present application is not limited to the specific steps described and shown, and those skilled in the art can make various changes, modifications and additions, or change the order of the steps, after understanding the spirit of the present application.

[0047] In the present application, the features described and / or exemplified for one embodiment can be used in the same way or in a similar way in one or more other embodiments, and / or in combination with or instead of the features of other embodiments.

[0048] The above merely provides the preferred embodiments of the present application, but not for limiting the present application.
