Description

Technical Field

[0001] This utility model relates to the technical field of resin-based fiber-reinforced composite material molding devices, specifically to a continuous rotating fiber laying head connector. Background Technology

[0002] Automated fiber bundle placement technology is widely used in the molding and manufacturing of high-performance composite material components in civilian fields such as aircraft shells, rocket shells, engines, S-shaped air intakes, high-performance pressure vessels, and automobile shells.

[0003] However, in the existing technology, due to the asymmetry of the end outlet of the automatic fiber tow placement equipment and the limited rotation angle of the fiber placement head, the automatic fiber tow placement equipment often requires a large number of reset movements to achieve placement at different positions of the mold during the composite material placement process. This results in a large number of "idle" ineffective movements during the molding process, which greatly reduces the molding efficiency of composite materials. In addition, continuous fiber variable angle composite material components have better mechanical properties than constant angle composite material components, but the rotation angle of the fiber placement head of the existing automatic fiber tow placement equipment is limited, and continuous free rotation cannot be achieved, which seriously limits the molding capability of continuous fiber variable angle fiber reinforced composite material components.

[0027] Example 1

[0028] refer to Figure 1 This embodiment provides a continuous rotating fiber placement head connector, including a support connector, a free rotation mechanism, a fiber placement connector, and a rotation drive mechanism. The fiber placement connector connects to the fiber placement head. The support connector is rotatably connected to the fiber placement connector via the free rotation mechanism, allowing the fiber placement connector to rotate continuously relative to the support connector without limitation on the rotation angle. The free rotation mechanism is signal-connected to the fiber placement connector for transmitting electrical signals. The rotation drive mechanism is drive-connected to the fiber placement connector, enabling rotation to a set number of revolutions and a set angle, while also controlling rotation parameters such as rotation direction and speed. This adapts to the molding of continuous fiber variable-angle fiber-reinforced composite material components, improves molding quality, and meets actual production needs.

[0029] Specifically, the free-rotating mechanism includes a photoelectric multifunctional integrated slip ring 2, which is connected between the fiber laying connector and the support connector. The fiber laying connector is signal-connected to the stationary end of the photoelectric multifunctional integrated slip ring 2 through the moving end of the slip ring 2.

[0030] At this time, the fiber placement connector can be connected to the moving end of the phos-electric multifunctional integrated slip ring 2, while the stationary end of the phos-electric multifunctional integrated slip ring 2 is connected to the support connector. The phos-electric multifunctional integrated slip ring 2 and the fiber placement connector are coaxially arranged. The rotation drive mechanism directly drives the fiber placement head to rotate as required by driving the fiber placement connector to rotate. The phos-electric multifunctional integrated slip ring 2 enables the fiber placement connector to achieve continuous rotation while maintaining the transmission of electrical signals.

[0032] To avoid excessive load on the connection between the fiber laying head and the moving end of the phos-electric integrated slip ring 2 during operation, which would reduce service life and reliability, it is preferable to use the rotary connector 3 to improve the overall structural strength, ensure the service life of the phos-electric integrated slip ring 2, and improve production stability and reliability.

[0033] The slewing connector 3 can be either a crossed roller bearing or a slewing support. Taking the crossed roller bearing as an example, the inner ring of the stationary end of the crossed roller bearing is fitted outside the stationary end of the phos-electric integrated slip ring 2. Both the stationary end of the crossed roller bearing and the stationary end of the phos-electric integrated slip ring 2 are detachably or fixedly connected to the support connector to ensure reliable connection. The moving end of the crossed roller bearing is connected to the fiber laying connector to provide load-bearing capacity and ensure the reliability of the phos-electric integrated slip ring 2.

The bottom of the connecting flange 8 is connected to the top of the fiber laying connector, preferably in a fixed connection. The top of the connecting flange 8 is detachably connected to the moving end of the rotary connector 3, which facilitates disassembly and assembly and enables quick replacement.

[0035] To further explain, the support connector includes a movable connecting seat 1 and a mounting plate 4.

[0036] During use, the moving mechanism of the laying equipment is connected to the support connector, and the fiber laying head is connected to the fiber laying connector. During the production process, the moving mechanism of the laying equipment drives the fiber laying head to move as needed through the support connector, while the rotation drive mechanism drives the fiber laying head to rotate as needed through the free rotation mechanism. At the same time, the free rotation mechanism is used to realize the transmission of electrical signals to ensure stable and reliable operation.

[0037] Example 2

[0038] Based on the continuous rotating fiber placement head connector described in Embodiment 1, this embodiment provides a continuous rotating fiber placement head connector in which the output end of the rotating drive mechanism is connected to the moving end of the rotary connector 3; that is, the rotating drive mechanism drives the moving end of the rotary connector 3 to rotate, and the moving end of the rotary connector 3 drives the fiber placement connector to rotate synchronously through the connecting flange 8, so as to ensure stable and reliable rotation.

[0039] Specifically, the rotary drive mechanism includes a rotary drive 5 and a transmission mechanism. The fixed end of the rotary drive 5 is connected to the mounting plate 4, and the output end of the rotary drive 5 extends through the mounting plate 4 to the bottom of the mounting plate 4.

[0040] The rotary drive 5 will be explained using a motor as an example.

[0041] The transmission mechanism includes a driving wheel 6 and a driven wheel 7. The driving wheel 6 is connected to the output end of the rotary drive 5, and the driven wheel 7 is sleeved on the outside of the moving end of the rotary connector 3.

[0042] The driving wheel 6 and the driven wheel 7 can be directly meshed or driven by a gear set, or they can be driven by a chain, belt or rack. The following is an example of driving wheel 6 and driven wheel 7 driven by a belt.

[0043] To further explain, the fiber laying connector includes a male connector 9 and a female connector 10. The top of the male connector 9 is connected to the bottom of the connecting flange 8. The male connector 9 is connected to the moving end signal of the PV-Electro-Hydro-Integrated Slip Ring 2.

This allows the female connector 10 to be pre-connected to the fiber laying head before use. During use, the female connector 10 connected to the fiber laying head can be directly plugged into the male connector 9. The operation is simple and convenient, thereby improving work efficiency.

[0044] The photoelectric multifunctional integrated slip ring 2 has a first electrical transmission component at its stationary end, a second electrical transmission component at its moving end, a third electrical transmission component in the connecting male disk 9, and a fourth electrical transmission component in the connecting female disk 10.
