Description

Technical Field

[0001] The present invention relates to the technical field of winding devices, and in particular to a composite material winding device based on an unmanned aerial vehicle. Background Art

[0002] The existing winding machines are divided into single-station winding equipment and multi-station winding equipment according to the number of stations. Each type of winding machine can be further divided into multiple types of winding machines in its own subdivision field. For example, it can be divided into vertical winding machines and horizontal winding machines according to the core mold winding method. The winding machines in the prior art have the following problems: the problem of winding efficiency. Single-station winding machines can usually only use one yarn outlet to wind one core mold at a time; the problem of insufficient degree of freedom. Usually, single-station winding machines are 3-axis or 4-axis. For some products with complex shapes, winding machines with more axes may be required, which will increase the corresponding equipment procurement cost; the overall utilization rate of the equipment is low. When a large-sized winding machine is used to wrap small products, the excess slide rail length will be wasted and cannot be expanded; the structure is relatively complex, and it is also more troublesome to use and maintain. Summary of the invention

[0003] In view of this, an embodiment of the present invention provides a composite material winding device based on a drone to eliminate or improve one or more defects existing in the prior art.

[0005] The core mold is clamped on the clamping mechanism, the spool is installed on the drone, the spool has a winding tape, one end of the winding tape is fixedly connected to the core mold, and the drone flies around the core mold to wind the winding tape around the core mold.

[0006] In one embodiment, at least two drones are provided, and at least two drones fly around the same core mold.

[0007] In one embodiment, the drone is provided with a battery or the drone is connected to a power source via a wire.

[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0025] It should also be noted that, unless otherwise specified, the term “connection” herein may refer not only to a direct connection but also to an indirect connection involving an intermediate.

[0026] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0027] Reference Figure 1The embodiment of the present invention provides a composite material winding device based on a drone, comprising: a clamping mechanism 1, a core mold 2, a drone 3 and a bobbin; the core mold 2 is clamped on the clamping mechanism 1, the bobbin is installed on the drone 3, the bobbin has a winding tape 4, one end of the winding tape 4 is fixedly connected to the core mold 2, and the drone 3 flies around the core mold 2 to wind the winding tape 4 on the core mold 2. The winding tape 4 can be carried by the drone, or a yarn rack can be placed on the ground, and the yarn passes through the drone for winding.

[0028] In the above embodiment, the automated winding process of the composite material (winding tape 4) is realized by carrying the bobbin on the drone 3 and controlling it to fly around the core mold 2. This improvement significantly improves the winding efficiency, reduces labor costs, and ensures the consistency and stability of the winding process. The flight path of the drone 3 can be programmably 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 products, improving the versatility and flexibility of the equipment. The precise flight control of the drone 3 can ensure that the winding tape 4 is evenly and tightly wound on the core mold 2, avoiding problems such as uneven thickness and poor overlap that may be caused by winding with a traditional winding machine. 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 drones 3 are provided, and at least two drones 3 fly around the same core mold 2. Multiple drones 3 can double the work efficiency by winding the same product. At the same time, the drone has 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, so as to improve the flexibility of winding. The drone can provide multiple degrees of freedom, so the winding is not limited to conventional winding methods such as rotating body winding, hole winding, and curved pipe winding.

[0030] In some embodiments, the drone 3 is provided with a battery or the drone 3 is connected to a power source via a wire. The drone can be a drone with its own power supply, which is more flexible, or a drone with a cable connection can be used to perform long-term operations.

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

[0032] In some embodiments, the composite winding device based on the drone also includes a slide rail 5, which is installed on the ground, and the clamping mechanism 1 is slidably connected to the slide rail 5 to adapt to core molds 2 of different lengths. The introduction of the slide rail 5 enables the clamping mechanism 1 to move horizontally on the ground, so as to easily adapt to core molds 2 of different lengths. This improvement breaks the limitation of the original device on the length of the core mold, so that the winding device can be applied to the production of more types of composite products, improving the versatility and market competitiveness of the equipment. By adjusting the position of the clamping mechanism 1 on the slide rail 5, the relative position relationship between the core mold 2 and the drone 3 can be flexibly changed. This helps to optimize the winding path, reduce the flight distance and time of the drone 3, and further improve the winding efficiency. At the same time, the sliding connection of the slide rail 5 also makes it possible to achieve more complex winding patterns and shapes.

[0033] Reference Figure 2 In some embodiments, at least two groups of clamping mechanisms 1 are provided, and at least two groups of clamping mechanisms 1 are arranged along the same horizontal axis for clamping at least two core molds 2 .

[0034] In some embodiments, the composite winding device based on the drone further includes a rotating drive member, which is used to drive the core mold 2 to rotate around its own axis. The rotating drive member can realize the self-rotation of the core mold 2 and the winding of the drone, which greatly improves the winding efficiency.

[0035] In some embodiments, the rotation driving member includes any one of an electric motor, a hydraulic motor, and an engine.

[0036] In some embodiments, the clamping mechanism 1 has a chuck or a top for centering the core mold 2. When multiple products need to be produced at the same time (with the same or different sizes), the slide rails can be modified to increase the number of slide rails and clamping mechanisms. The placement method can be based on actual site requirements. It is not limited to the same horizontal line as 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 tooling needs to be strength-checked, and the cantilever clamping method may produce larger displacements than the double-sided clamping method, depending on the product), the cantilever clamping method can be used, and only one side is clamped; when clamping large-sized products, both sides need to be clamped to reduce deformation and improve the accuracy of the core mold.

[0038] The existing problems of multi-station wrapping machines are as follows: Like single-station wrapping machines, multi-station wrapping machines are also difficult to use and maintain; multi-station wrapping machines can wrap multiple products at the same time, but generally multi-station wrapping machines are arranged in an up-down manner. When the winding diameter of one product interferes with the next row of products, multiple products cannot be wrapped at the same time. There are strong limitations; multi-station wrapping machines usually have a small bearing capacity for the core mold, which is not conducive to the winding of large products.

[0039] The composite winding device based on drone in the above embodiment uses unmanned equipment to replace the wire-extracting method of the traditional runway winding machine, which improves the flexibility of the expansion of the winding equipment. If multiple drones are used for winding at the same time, the efficiency is many times that of the traditional winding equipment. Through the flexibly adjustable clamping mechanism, the production of winding products of any length can be achieved. Even if the clamping mechanisms on both sides may cause slight misalignment due to length reasons, it can be compensated by the freedom of the drone. It can also achieve winding of almost any shape, such as axisymmetric, conical, three-way pipe, elbow and other forms.

[0040] The advantages of the composite material winding device based on the drone in this embodiment compared with the single-station winding machine are as follows:

[0041] 1. Efficiency can be improved by expanding drones;

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

[0043] 3. A winding method with high degree of freedom can be achieved;

[0044] 4. The core mold can be kept from rotating and completely wound by the drone;

[0045] The advantages of the composite material winding device based on the drone of this embodiment compared to the multi-station winding machine are: it can be arranged horizontally instead of the vertical arrangement of the traditional multi-station winding machine, and the arrangement method is more flexible.

[0046] It should be clear that the present invention is not limited to the specific configuration and processing described above and shown in the figures. For the sake of simplicity, a detailed description of the known method is omitted here. In the above embodiments, several specific steps are described and shown as examples. However, the method process of the present invention 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 between the steps after understanding the spirit of the present invention.
