[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please refer to Figures 1-5. In this embodiment of the invention, a processing device for winding carbon fiber for helicopter rotor includes a frame 1. Both ends of the frame 1 are fixedly connected to drive motors 2. The output ends of the two drive motors 2 are fixedly connected to snap-fit ​​blocks 3. The snap-fit ​​blocks 3 are provided with snap-fit ​​grooves for snap-fitting and fixing the ends of the helicopter rotor. By setting two snap-fit ​​blocks 3, the ends of the helicopter rotor are snap-fitted and limited, ensuring the stability of the helicopter rotor during the winding process. The two drive motors 2 drive the two snap-fit ​​blocks 3 to rotate, thereby driving the helicopter rotor to rotate, realizing the traction and winding of carbon fiber.

[0020] A guide and limiting mechanism for limiting carbon fibers is fixedly installed in the middle of the inner wall of the frame 1. The guide and limiting mechanism includes a mounting frame 4, a positioning groove 5 is opened in the middle of the mounting frame 4, and several limiting parts are slidably connected to the inner wall of the positioning groove 5. An adjusting motor is fixedly connected to the bottom of the sliding plate, and a limiting strip 10 is fixedly connected to the output end of the adjusting motor. A limiting contact piece is fixedly connected to the bottom of the limiting strip 10, and several balls are rotatably connected to the bottom of the limiting contact piece. All the limiting strips 10 are set to arc shape. When the carbon fibers are wound, the limiting strips 10 are rotated by the adjusting motor, so that the balls on the limiting contact piece contact the helicopter rotor. During the winding process, the carbon fibers are blocked and limited, thereby ensuring that the spacing of the carbon fibers on the helicopter rotor is uniform.

[0021] Due to the unique shape of the helicopter rotor, in order to ensure uniform winding at different positions, the spacing of the limiting strips 10 at different positions needs to be flexibly adjusted. To facilitate the adjustment of the spacing of each limiting strip 10, the limiting component includes a sliding plate, with a locking bolt 9 threadedly connected in the middle of the sliding plate, and an upper pressure plate 6 slidably connected in the middle of the locking bolt 9. The width of the upper pressure plate 6 is greater than the width of the positioning groove 5.

[0022] The top of the mounting bracket 4 has several equally spaced limiting slots 8. Each of the upper pressure plates 6 has a snap-fit ​​plate 7 fixedly connected to one side. The bottom of the snap-fit ​​plate 7 engages with the inner wall of the limiting slot 8. The cooperation between the snap-fit ​​plate 7 and the limiting slot 8 improves the stability of the spacing between each limiting component and makes it easier to judge and control the spacing between each limiting component.

[0023] A feeding mechanism for supplying carbon fiber is fixedly installed on one side of the inner wall of the frame 1. The feeding mechanism includes a shifting guide rail 11, a turntable frame 12 is slidably connected to the inner wall of the shifting guide rail 11, and a feeding turntable 13 is rotatably connected to the inner wall of the turntable frame 12. A feeding motor for driving the feeding turntable 13 to rotate is fixedly installed on one side of the turntable frame 12. Carbon fiber is wound on the outer wall of the feeding turntable 13. The feeding turntable 13 is moved by the shifting guide rail 11 to achieve winding at various positions of the helicopter rotor. The winding speed is controlled by controlling the speed at which the feeding turntable 13 is moved by the shifting guide rail 11 and the speed at which the feeding motor rotates.

[0024] A limiting cutting mechanism is fixedly installed at the bottom of the turntable frame 12. The limiting cutting mechanism includes a support plate 14. A guide groove 15 is opened on the top of the support plate 14. A cutting blade 18 is fixedly installed on one side of the inner wall of the guide groove 15. A cutting pad 17 is embedded on the other side of the inner wall of the guide groove 15. By setting the cutting blade 18, the carbon fiber is cut after the winding operation of the helicopter rotor is completed, so as to facilitate the removal operation of the helicopter rotor.

[0025] Two symmetrically arranged pressure plates 16 are fixedly connected to one end of the inner wall of the guide groove 15. The middle part of the two pressure plates 16 is bent downward. The carbon fiber is pressed by the pressure plates 16 to ensure that the carbon fiber on the feeding turntable 13 can be stably fed out by the guide groove 15.

[0026] A docking mechanism is fixedly installed on the inner wall of the frame 1. The docking mechanism includes a docking cylinder 20. A bracket is fixedly connected to the output end of the docking cylinder 20. An electric gripper 21 is fixedly installed on one side of the bracket. An electric telescopic rod is fixedly installed at the bottom of the bracket. An adjusting frame 22 is fixedly connected to the bottom of the electric telescopic rod. A dispensing head 23 is fixedly installed on the top of the adjusting frame 22. The dispensing head 23 is fixedly connected to an external adhesive supply device. The electric gripper 21 clamps the carbon fiber fed from the guide groove 15, making it fit against the helicopter rotor, in conjunction with the dispensing head 23. The adhesive is used to fix the ends of the carbon fiber, making the position of the carbon fiber more stable during the winding process. The height of the guide groove 15 of the feeding mechanism is located below the helicopter rotor, so that the feeding position of the carbon fiber is also located below the helicopter rotor. The limiting contact pieces on several limiting strips 10 maintain contact with the upper part of the helicopter rotor through their own elasticity, thereby preventing the wound carbon fiber from shifting under the pulling action of the subsequent carbon fiber, and also preventing the limiting strips 10 from obstructing the feeding operation of the feeding turntable 13.

[0027] By combining the limiting cutting mechanism and the docking mechanism, the connection and cutting operations of carbon fiber can be carried out automatically, improving the overall automation level and work efficiency of the device.

[0028] The support plate 14 has a movable groove 19 at one end facing the docking mechanism, which corresponds to the electric gripper 21. By setting the movable groove 19, the electric gripper 21 is provided with a movable space for the gripping operation, ensuring that the electric gripper 21 can stably grip the carbon fiber.

[0029] When in use, the present invention feeds the helicopter rotor to be processed into the frame 1 through an external feeding device, and makes the two ends of the helicopter rotor engage with the locking grooves on the two locking blocks 3 respectively, thereby limiting the position of the helicopter rotor.

[0030] The docking cylinder 20 is activated, causing the adjusting frame 22 to move forward, so that the electric gripper 21 moves to the position of the movable slot 19 and clamps the carbon fiber. Then, the docking cylinder 20 drives the electric gripper 21 to move to the underside of the helicopter rotor. The electric telescopic rod is activated, causing the adjusting frame 22 to rise, so that the dispensing head 23 rises, lifts the carbon fiber and contacts the helicopter rotor to dispense adhesive, and fixes the end of the carbon fiber. Then, the electric telescopic rod drives the adjusting frame 22 to reset, and the docking cylinder 20 drives the hanger to reset.

[0031] Two drive motors 2 drive two locking blocks 3 to rotate, which in turn drives the helicopter rotor to rotate, pulling the carbon fiber to rotate and winding it around the helicopter rotor. At the same time, the shifting guide rail 11 drives the feeding turntable 13 to move, winding several carbon fiber rings on the helicopter rotor. During winding, the corresponding adjustment motor drives the limiting strip 10 to rotate, so that the ball bearings on the limiting contact piece make contact with the helicopter rotor, blocking several rings of carbon fiber and preventing them from shifting under the pulling action of the feeding turntable 13, ensuring that the carbon fiber is wound evenly. After the carbon fiber is wound, the cutting blade 18 starts to cut the carbon fiber, several adjustment motors reset, and then the feeding motor starts, driving the feeding turntable 13 to rotate, sending the carbon fiber out of the guide groove and letting it fall naturally to the position of the movable groove 19 for subsequent winding processing operations.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
