Abstract
Description
Technical Field
[0001] This invention relates to the field of automated manufacturing and processing technology, and particularly to a modular prepreg cutting machine. Background Technology
[0002] Prepreg is an intermediate material composed of a resin matrix and reinforcing fibers. In its incompletely cured state, it exhibits excellent plasticity and adhesion, and is widely used in aerospace, automotive manufacturing, electronic packaging, and high-performance composite material products. Due to the high requirements for dimensional accuracy and surface quality in subsequent molding processes, it typically needs to be precisely cut according to product specifications before use.
[0003] Traditional prepreg cutting is mostly done manually or with simple mechanical devices, which is not only inefficient but also difficult to meet different size requirements, limiting its application in automated production. Currently available prepreg cutting equipment generally suffers from low functional integration, inconvenient adjustment, low cutting precision, and weak dust handling capabilities. Most equipment lacks modular design, leading to difficult maintenance, poor adaptability, and an inability to quickly replace or adjust to meet the processing needs of different material specifications. These problems affect cutting quality and production efficiency, and also hinder the further promotion and application of prepreg in high-end manufacturing.
[0004] Therefore, a modular prepreg cutting machine needs to be designed to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation
[0022] Example: A modular prepreg cutting machine, such as Figures 1-5 As shown, the assembly includes a frame 1, a servo motor 3, guide rollers 4, a mounting bracket 5, a guide rail 6, a rodless cylinder 9, a connecting plate 8, a sliding plate 7, a pneumatic gripper 10, a clamping plate 11, a rubber block 111, an electric slide rail 12, a laser cutting module 13, a base plate 16, and a heat sink 14. A servo motor 3 with its output shaft pointing horizontally to the left is installed on the lower front side of the frame 1 to control the winding of the prepreg 2. A guide roller 4 is installed on the top front side of the frame 1 to provide sliding guidance for the prepreg 2. A mounting bracket 5 is bolted to the top front side, with guide roller 4 located in front of the mounting bracket 5. Guide rails 6 are mounted on the adjacent sides of the mounting bracket 5. A rodless cylinder 9 is located on the top front side of the frame 1, corresponding to the left side of the mounting bracket 5. A connecting plate 8 extending to the right is slidably connected to the rodless cylinder 9. The rodless cylinder 9 is used to drive the connecting plate 8 to move back and forth. A sliding plate 7 is bolted to the bottom right side of the connecting plate 8, and the guide rails 6 are used for sliding plate 7. The guide is slidably connected to the left side of the slide plate 7 and the left side of the mounting frame 5, and slidably connected to the right side of the slide plate 7 and the right side of the slide plate 7, thereby realizing the guiding movement. Pneumatic grippers 10 are symmetrically installed on the left and right sides of the bottom of the slide plate 7. Each pneumatic gripper 10 controls vertically arranged clamping plates 11. The clamping plates 11 are used to clamp the prepreg 2. Rubber blocks 111 are hinged to the sides of the two clamping plates 11 that are close to each other to reduce wear during clamping. An electric slide rail 12 is installed inside the front side of the mounting frame 5. A laser cutting module 13 is horizontally slidably connected to the rear side of the electric slide rail 12. The top of the frame 1 is connected to the base plate 16 by bolts in the middle of the mounting frame 5. The prepreg 2 to be cut is placed there. A heat sink 14 is fixedly placed on the top of the frame 1 directly below the laser cutting module 13. The heat sink 14 is located in front of the base plate 16. It is used to receive the residual laser after the laser cutting is completed to prevent damage to the frame 1. The heat sink 14 is a consumable and can be replaced.
[0023] like Figure 1 and Figure 5As shown, it also includes mounting bracket 2 51, guide rod 1 17, rodless cylinder 2 18, slide 19, cylinder 3 20, guide rod 2 171, mounting plate 21, pneumatic suction cup 22, and material frame 23. Mounting bracket 2 51 is symmetrically installed on the top of the frame 1, and mounting bracket 1 5 and rodless cylinder 1 9 are both located inside the front side of mounting bracket 2 51 on both sides. Guide rod 1 17 is symmetrically connected to the top of mounting bracket 2 51 on both sides by bolts. Rodless cylinder 2 18 is installed between the top of mounting bracket 2 51 at the middle position of the two guide rods 17. Slide 19 is slidably connected to rodless cylinder 2 18. Driven by rodless cylinder 2 18 and guided by guide rod 1 17, cylinder 3 20 with vertically downward output shaft is installed in the middle of the top of slide 19. Mounting plate 21 is connected to the output shaft by bolts. Multiple pneumatic suction cups 22 are provided at the bottom of mounting plate 21 for adsorbing the cut semi-cured sheet 2. Guide rod 2 171 is connected to the top left and right sides of mounting plate 21 by bolts. Guide rod 2 171 is slidably connected to slide 19 to further provide guidance. A slot is opened on the top rear side of frame 1. Material frame 23 is slidably placed under the slot of frame 1 for collecting the cut semi-cured sheet 2.
[0024] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a damper 15, a suction pipe 24, a fan 25, and a dust collection box 26. The front and rear sides of the mounting frame 1 5 are respectively equipped with dampers 15, and the front damper 15 is located above both sides of the electric slide rail 12 to provide movement buffer for the slide plate 7 on the mounting frame 1 5. The front and rear sides of the mounting frame 2 51 are also equipped with dampers 15 to provide movement buffer for the mounting plate 21. The top front side of the frame 1 is located between the guide roller 4 and the mounting frame 1 5, and a suction pipe 24 is provided. A material inlet is opened in the middle of the suction pipe 24. A fan 25 is installed on the right side of the suction pipe 24, and a dust collection box 26 is connected to the right side of the fan 25 to remove the dust generated during the cutting process.
[0025] Before starting the operation, the operator installs the prepreg roll 2 onto the output shaft of the servo motor 3, and places one end of the material on the guide roller 4, passing it through the feed inlet of the suction pipe 24 and laying it flat on the surface of the base plate 16. After confirming that the position is correct, the system is started. First, the servo motor 3 drives the roll to slowly release the material, so that the prepreg 2 is pulled out from the roll end and laid on the base plate 16. At this time, the pneumatic gripper 10 located at the bottom of the slide plate 7 drives the two clamping plates 11 to simultaneously clamp the edge of the material. The rubber blocks 111 on the inner side of the clamping plates 11 effectively prevent damage to the material during the clamping process. After clamping is completed, the rodless cylinder 9 drives the connecting plate 8 to move backward, driving the slide plate 7 to move laterally along the guide rail 6, thereby pulling the clamped prepreg 2 to the right to stretch to a suitable length. When the material is stretched to a suitable length, the pneumatic gripper 10 releases the clamping plates 11, the rodless cylinder 9 drives the connecting plate 8 to move forward, and the slide plate 7 returns to the initial position under the guidance of the guide rail 6, thus completing one reset action. Subsequently, clamp 11 clamps another section of the material again, positioning it for cutting. This clamping-stretching-releasing-resetting-re-clamping process can be repeated to accommodate cutting requirements of different lengths.
[0026] After material positioning is completed, the electric slide rail 12 drives the laser cutting module 13 to move horizontally, performing non-contact precision cutting on the prepreg 2. Dust generated during the cutting process is sucked in by the dust suction pipe 24 and transported to the dust collection box 26 by the fan 25, maintaining a clean environment and protecting the equipment's precision. To prevent residual laser from damaging the frame 1, a heat sink 14 is located directly below the laser cutting area to absorb excess energy and can be replaced as needed.
[0027] After cutting, the pneumatic gripper 10 releases the clamping plate 11, and the rodless cylinder 18 on the top of the mounting frame 51 is activated, which drives the slide 19 forward along the guide rod 17 to above the cut finished product. Then, the cylinder 20 on the slide 19 extends downward, bringing the mounting plate 21 close to the material surface. Multiple pneumatic suction cups 22 at its bottom are ventilated to adsorb the cut semi-cured sheet 2. The cylinder 20 retracts, and the slide 19 drives the mounting plate 21 to move backward to the rear of the frame 1, transferring the finished product to above the material frame 23. The pneumatic suction cups 22 are de-ventilated and released, and the finished product falls into the material frame 23 through the slot, completing one complete cutting cycle. The guide rod 171 cooperates with the slide 19 to provide guidance and ensure that the suction cup operation is stable and reliable.
[0028] Throughout the entire operation, the dampers 15 on mounting frame 1 5 and mounting frame 2 51 respectively buffer the movement of the slide plate 7 and mounting plate 21, reduce vibration, and improve the smoothness of operation. The entire process is highly automated and can adapt to different size cutting requirements, achieving efficient, precise and stable processing of the prepreg 2.
