[0002] Composite materials are increasingly widely used in aerospace, weaponry, and other industrial fields due to their advantages such as high specific strength, high specific modulus, good fatigue resistance, and corrosion resistance. Prepreg is a combination of resin matrix and reinforcement, made by impregnating continuous fibers or fabrics with a resin matrix under strictly controlled conditions. Prepreg is an intermediate material in advanced composite materials and is the basic unit of composite structure. The mechanical and chemical properties of composite materials largely depend on the intrinsic quality of the prepreg. Currently, advanced composite materials are mainly manufactured using autoclave and press hot pressing technology, in which prepreg layup is an important step in the composite material molding process.

[0029] 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.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1-5 The present invention provides a non-contact pneumatic layup device for fiber-reinforced metal laminates, comprising:

[0032] Machine base 1, with a movable component installed at its bottom;

[0033] A spatial movement mechanism is installed on the top of the machine base 1, and a mounting base 2 is installed on the spatial movement mechanism;

[0034] Mounting bracket 3 is installed at the bottom of mounting base 2, and mounting bracket 3 has a ring structure;

[0035] Telescopic arms, wherein several sets of telescopic arms are provided, and several sets of telescopic arms are fixedly connected to the mounting frame 3 at equal intervals in the circumference. Each end of the telescopic arm is respectively equipped with an openable and closable gripper.

[0036] A jet mechanism is installed at the middle position of the mounting bracket 3;

[0037] The machine base 1 is equipped with a positioning platform 4 on its top surface, and the mounting frame 3 is correspondingly positioned with respect to the positioning platform 4.

[0038] In use, the bottom aluminum alloy plate is first fixed on the positioning table 4, and a prepreg of the corresponding shape is cut. The telescopic arm at the corresponding position is controlled according to the shape of the prepreg. The telescopic arm, in conjunction with the openable and closable gripper, grabs the prepreg. The spatial movement mechanism drives the mounting base 2 and the mounting frame 3 to move. When it moves to directly above the bottom aluminum alloy plate, the openable and closable gripper releases the prepreg, and the prepreg is laid on the bottom aluminum alloy plate. Then, the air jet mechanism applies gas pressure to the prepreg to achieve non-contact laying. After the laying is completed, the upper aluminum alloy plate is laid on the upper layer of the prepreg. Finally, the material is pressed by a press to complete the material preparation.

[0039] This invention uses a telescopic arm in conjunction with an openable gripper for laying prepreg, which reduces the difficulty of manual operation and improves work efficiency.

[0040] In a further optimized scheme, the spatial movement mechanism includes brackets 5 symmetrically fixedly connected to the top of the machine base 1. Tracks 6 are fixedly connected to the top of each bracket 5, and sliders 7 are slidably connected to the tracks 6. A connecting plate 8 is fixedly connected between two sliders 7. A Y-axis linear motor 9 is mounted on the top of one of the brackets 5, and the connecting plate 8 is fixedly connected to the Y-axis linear motor 9 via a fixing plate. A frame 10 is fixedly connected to the top surface of the connecting plate 8, and two X-axis linear motors 11 are fixedly connected in parallel to the frame 10. The X-axis linear motors 11 are perpendicular to the Y-axis linear motors 9. Mounting arms 12 are fixedly connected to each of the two X-axis linear motors 11, and Z-axis telescopic rods 13 are fixedly connected to the bottom of each mounting arm 12. The Z-axis telescopic rods 13 are perpendicular to the X-axis linear motors 11 and the Y-axis linear motor 9. The mounting base 2 is detachably connected to the output shafts of the two Z-axis telescopic rods 13.

[0041] The Y-axis linear motor 9 controls the movement of the connecting plate 8, and the two X-axis linear motors 11 work together to control the mounting arm 12 to move closer or further away, ensuring that the device can be used with mounting bases 2 of different sizes. The Z-axis telescopic rod 13 allows the mounting frame 3 at the bottom to rise and fall vertically, facilitating the clamping operation of the device.

[0042] In a further optimized design, the telescopic arm includes a support plate 14 fixedly connected to the mounting frame 3. The axis of the support plate 14 is collinear with the diameter line of the mounting frame 3. An internally threaded tube 15 is slidably connected to the top surface of the support plate 14. One end of the internally threaded tube 15 is fixedly connected to the openable gripper, and the other end of the internally threaded tube 15 is threadedly connected to a threaded rod 16. An annular groove 17 is formed on the top surface of the mounting frame 3. A transmission assembly is installed in the annular groove 17. One end of the threaded rod 16 passes through the side wall of the mounting frame 3 and extends into the annular groove 17, engaging with the transmission assembly. A bearing seat is installed in the annular groove 17, and the threaded rod 16 is rotatably connected to the bearing seat.

[0043] In a further optimized scheme, the transmission assembly includes a drive ring 18 rotatably connected within the annular groove 17. The drive ring 18 is coaxially arranged with the mounting bracket 3. The cross-sectional shape of the drive ring 18 is a right trapezoid. A first tooth groove is provided on the inclined surface of the drive ring 18. A first electrically controlled telescopic rod 19 is fixedly connected to the end of the threaded rod 16. A first bevel gear 20 is fixedly connected to the output end of the first electrically controlled telescopic rod 19. The drive ring 18 meshes with the first bevel gear 20 through the first tooth groove. A drive gear 21 is rotatably connected within the annular groove 17. A second tooth groove is provided on the outer wall of the drive ring 18. The drive ring 18 meshes with the drive gear 21 through the second tooth groove. The diameter of the drive gear 21 is smaller than the diameter of the drive ring 18. A first drive motor 22 is fixedly connected to the mounting base 2. The output shaft of the first drive motor 22 is axially connected to the drive gear 21.

[0044] In a further optimized design, the openable gripper includes a connecting rod 23 fixedly connected to the end of the internally threaded tube 15. The connecting rod 23 is perpendicular to the internally threaded tube 15. A pad 24 is fixedly connected to one end of the connecting rod 23. The pad 24 is perpendicular to the connecting rod 23. A second electrically controlled telescopic rod 31 is rotatably connected to the pad 24. A clamping plate 25 is fixedly connected to the output section of the second electrically controlled telescopic rod 31. A second drive motor 30 is fixedly connected to the side wall of the connecting rod 23. The output shaft of the second drive motor 30 is fixedly connected to the top end of the second electrically controlled telescopic rod 31. Several air nozzles 26 are installed on the pad 24.

[0045] The second drive motor 30 controls the drive gear 21 to rotate, which in turn drives the drive ring 18 to rotate. The telescopic arm at the corresponding positioning point is selected according to the actual laying shape, and the first electrically controlled telescopic rod 19 on the corresponding telescopic arm is extended. The bevel gear is connected to the drive ring 18, and the telescopic arm not involved in the positioning is in a stationary state. The drive ring 18 drives the bevel gear to rotate, which in turn drives the threaded rod 16 to rotate. The threaded rod 16 controls the internal threaded tube 15 to slide along the axial direction, thereby realizing the extension and retraction of the telescopic arm. Multiple telescopic arms cooperate to grab the prepreg through the openable grippers at the ends, and then move to the top of the positioning platform 4 through the spatial moving mechanism. The laying posture is adjusted, the prepreg is put down, and then the air jet mechanism applies gas pressure to complete the laying of the prepreg.

[0046] The second drive motor 30 controls the second electrically controlled telescopic rod 31 to rotate, thereby driving the clamping plate 25 to rotate and realize the opening and closing of the gripper. The second electrically controlled telescopic rod 31 can bring the clamping plate 25 closer to the pad 24 to complete the clamping. In this embodiment, a roller is rotatably connected to the top of the clamping plate 25. The roller can reduce the relative friction between the clamping plate 25 and the prepreg. At the same time, an anti-stick coating is applied to the roller to prevent adhesion.

[0047] In a further optimized design, the clamping plate 25 is coated with an anti-stick coating. The anti-stick coating utilizes existing technology, and the specific model is selected based on actual needs; no specific limitation is made in this embodiment.

[0048] In a further optimized design, the jet mechanism includes a mounting pipe 27 fixedly connected to the center of the mounting frame 3. A mounting plate 28 is fixedly connected to the bottom of the mounting pipe 27. Several jet nozzles 26 are mounted on the mounting plate 28. An air supply pipe is installed inside the mounting pipe 27. The air supply pipe is connected to the jet nozzles 26 through a split pipe. The air supply pipe is also connected to an air supply device.

[0049] The entire device is supplied with air by an air supply device, which is connected to the air nozzle 26 on the mounting plate 28 through an air supply pipe, and connected to the air nozzle 26 on multiple openable and closable grippers through a branch pipe. At the same time, an electromagnetic control valve is installed on the branch pipe to realize the air supply control of individual openable and closable grippers. The air nozzle 26 allows for non-contact laying of the prepreg on the bottom aluminum alloy plate, so that the prepreg and the bottom aluminum alloy plate are completely bonded. This ensures the laying effect while reducing the laying difficulty. The mounting plate 28 can provide gas pressure to the middle position, while the nozzles on the openable and closable grippers can provide gas pressure to the edge part. In actual operation, the middle part needs to be laid first, and the edge part is laid after the middle part is completely adhered. This can reduce air bubbles between the prepreg and the bottom aluminum alloy plate and ensure complete adhesion. At the same time, in this embodiment, an annular slide rail can be installed at the bottom of the mounting base 2, and the mounting frame 3 is rotatably connected to the annular slide rail. The annular slide rail is electrically driven, so that the mounting frame 3 can rotate. In this way, the laying angle can be adjusted during laying, and gas pressure can be evenly provided to the outer edge part of the laying to complete the edge sealing of the laying and ensure the laying effect.

[0050] In a further optimized design, the moving component includes casters 29, and several sets of casters 29 are provided, with several casters 29 symmetrically installed at the bottom of the machine base 1.

[0051] The omnidirectional wheels 29 allow the device to move as needed, improving its flexibility. The omnidirectional wheels 29 are equipped with a braking assembly, which utilizes existing technology.
