Description

Technical Field

[0001] This invention relates to the field of composite material winding technology, and more particularly to a carbon fiber prepreg winding device. Background Technology

[0002] In the current development of carbon fiber wheels, the HOOK position of the wheel (i.e., the wheel bead hook, located on both sides of the wheel edge, is an inwardly curved hook-shaped structure used to lock the tire bead) is crucial. This part needs to withstand the high pressure locking force after the tire is inflated, as well as the lateral impact load during riding. Therefore, its reinforcement technology has become a core technical link to ensure the overall safety and long-term durability of the wheel.

[0003] Carbon fiber prepreg is a sheet or strip composite material made by pre-impregnating continuous carbon fibers (such as tows or fabrics) in an incompletely cured resin system and processing them under strictly controlled conditions. In the early stages of carbon fiber wheel development, specific types of carbon fiber prepregs were typically used in conjunction with special winding processes to ensure that the mechanical properties of the wheels met predetermined standards. However, traditional manual winding methods have significant drawbacks: they require a large amount of manual time for the winding operation and also necessitate additional effort to handle the waste generated during production. This directly leads to an extended production cycle, thus significantly limiting the large-scale production of carbon fiber wheels.

[0004] Therefore, there is an urgent need for a carbon fiber prepreg winding device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a carbon fiber prepreg winding device that can effectively improve the efficiency of carbon fiber prepreg winding and reduce labor costs.

[0035] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 3As shown, this embodiment provides a carbon fiber prepreg winding device, which includes: a feeding tray 1, a first driving member 2, a take-up tray 3, a second driving member 4, a take-up tray 5, and a third driving member 6. The first driving member 2 can drive the feeding tray 1 to rotate so that the feeding tray 1 releases the carbon fiber prepreg with release paper. The second driving member 4 can drive the take-up tray 3 to rotate so that the take-up tray 3 peels the release paper from the carbon fiber prepreg and gathers it. The third driving member 6 can drive the take-up tray 5 to rotate so that the carbon fiber prepreg after peeling off the release paper is wound onto the take-up tray 5. The carbon fiber prepreg is in the form of a strip. With this configuration, the first drive unit 2, the second drive unit 4, and the third drive unit 6 are configured to rotate in a controlled manner to perform the following actions sequentially and continuously: releasing carbon fiber prepreg with release paper from the feed tray 1, peeling the release paper from the prepreg and gathering it by the take-up tray 3, and winding the peeled carbon fiber prepreg onto the take-up tray 5. This achieves efficient and stable automated winding of carbon fiber prepreg for carbon fiber wheel rims, effectively improving the efficiency of carbon fiber prepreg winding and reducing labor costs.

[0037] It should be noted that multiple wrappings of carbon fiber prepreg are used to reinforce the HOOK area of ​​the wheel rim, ensuring stable performance.

[0038] In this embodiment, the carbon fiber prepreg winding device further includes a frame 7, a worktable 8, and a support platform 9. The support platform 9 is fixedly mounted on the frame 7, the worktable 8 is fixedly mounted on the support platform 9, the first driving member 2 and the second driving member 4 are both fixedly mounted on the worktable 8, and the third driving member 6 is fixedly mounted on the support platform 9.

[0039] Optionally, in order to ensure the stability and reliability of carbon fiber prepreg transmission, the carbon fiber prepreg winding device also includes a guide assembly, which is fixedly mounted on the worktable 8 and is used to guide the carbon fiber prepreg to be wound onto the receiving tray 5.

[0040] Specifically, this embodiment provides the following exemplary technical solution: the guiding assembly includes a first guide roller 10 and a second guide roller 11, both of which are disposed between the feeding tray 1 and the receiving tray 5. Carbon fiber prepreg is sequentially wound around the first guide roller 10 and the second guide roller 11. This arrangement, through the precise positioning and tension control of the first guide roller 10 and the second guide roller 11, ensures that the carbon fiber prepreg maintains a stable running trajectory and uniform tension during subsequent processing. The reasonable arrangement of the guide rollers not only helps reduce material deviation and wrinkling during transmission but also effectively improves the prepreg's laying accuracy, laying a good foundation for subsequent curing and molding processes, thereby ensuring the quality stability and performance consistency of the final product.

[0041] Furthermore, the guiding assembly also includes a support block 12, which is fixedly mounted on the worktable 8. The support block 12 has a guide hole 121. The carbon fiber prepreg is wound sequentially around the first guide roller 10 and the second guide roller 11, and passes through the guide hole 121 to be wound onto the take-up tray 5. With this configuration, during the winding process, the carbon fiber prepreg is first initially guided and tension-controlled by the first guide roller 10, and then continues to be wound onto the second guide roller 11 to further adjust the running trajectory and ensure the flatness of the material. Afterward, the carbon fiber prepreg path is precisely positioned through the set guide hole 121 to avoid deviation and reduce running resistance. Finally, after the guiding and positioning processes, the carbon fiber prepreg is stably wound onto the take-up tray 5 to form a neat and orderly roll.

[0042] Optionally, in order to ensure high stability of the winding process, the carbon fiber prepreg winding device also includes a clamping assembly 13. The output end of the third drive member 6 is connected to the clamping assembly 13 and can drive the clamping assembly 13 to rotate. The clamping assembly 13 is used to clamp and fix the take-up tray 5.

[0043] Optionally, the take-up tray 5 includes an upper mandrel 51 and a lower mandrel 52. The lower mandrel 52 is clamped and fixed to the clamping assembly 13. The upper mandrel 51 is embedded in the lower mandrel 52 to form a gathering annular groove 53, which is used for winding the carbon fiber prepreg. This arrangement gathers the carbon fiber prepreg into the gathering annular groove, and the tension during take-up further makes the wound product more compact, effectively improving winding efficiency and finished product quality, and laying a good foundation for subsequent processing.

[0044] This enables independent control and precise coordination of the three key processes: peeling, feeding, and winding, ensuring high stability and efficiency in carbon fiber prepreg winding operations.

[0045] In this embodiment, the first driving component 2, the second driving component 4, and the third driving component 6 are all drive motors. Furthermore, the third driving component 6 is a servo motor, which can adjust the length of the carbon fiber prepreg according to actual needs.

[0046] Optionally, the rotation directions of the first driving member 2 and the second driving member 4 are configured such that the peeling direction of the release paper forms an acute angle or is opposite to the feeding direction of the carbon fiber prepreg at the peeling station. This configuration, by controlling the rotation directions of the first driving member 2 and the second driving member 4, creates a directional difference between the release paper and the prepreg at the peeling point, thereby utilizing shear force to achieve smooth, low-damage peeling of the release paper. This effectively prevents the prepreg fibers from deforming or breaking due to tension, ensuring the integrity of the wound material.

[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
