Description

Technical Field

[0001] This invention relates to the field of automatic carbon fiber composite material laying equipment, and more particularly to a carbon fiber laying equipment. Background Technology

[0002] Carbon fiber prepregs, with their superior properties such as high specific strength, high modulus, corrosion resistance, and fatigue resistance, are widely used in aerospace, wind power, rail transportation, and high-end equipment. Automated layup technology is the core process for carbon fiber composite molding, which achieves automated molding of composite components through continuous conveying, laying, and cutting of prepreg filaments.

[0003] Existing carbon fiber layup equipment suffers from several technical shortcomings in practical applications: First, the slit and cutting structures of traditional layup equipment are mostly arranged separately, resulting in a fragmented structure, low integration, large equipment size, and poor adaptability; second, conventional cutters mostly use a sharp straight-blade structure, which easily tears carbon fiber bundles during the cutting process, causing broken fibers, fuzzing, and layup wrinkles, seriously affecting the quality of component forming; third, existing cutting mechanisms lack a flexible pressure-bearing and precise material-pressing linkage structure, making it easy for prepreg to slip and shift during the cutting process, resulting in uneven slits and low cutting dimensional accuracy; at the same time, traditional blades are fixedly installed, making it impossible to flexibly adjust the slit depth and slit spacing according to different specifications of prepreg, resulting in poor adaptability. Summary of the Invention

[0004] Therefore, in response to the above problems, this invention proposes a carbon fiber laying device, which solves the technical problems of existing equipment such as split cutting, easy fiber breakage at the cutting seam, low cutting accuracy, and poor adaptability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: including a fixed substrate, a pressure regulating component fixedly installed on the upper right side of the fixed substrate, a carbon fiber feeding tray disposed on the left edge of the fixed substrate, a front feeding wheel installed on the surface of the fixed substrate and disposed near the pressure regulating component, a servo feeding mechanism located behind the front feeding wheel and having differential speed compensation function, a laying and cutting assembly located behind the servo feeding mechanism, and a carbon fiber laying head installed on the lower surface of the fixed substrate, wherein a temperature detector and an infrared heater are provided behind the carbon fiber laying head; The laying and cutting assembly includes an elastic pressure-bearing component and a slit cutting device arranged along the carbon fiber feeding direction. An auxiliary pressing structure is provided on the side of the slit cutting device. The elastic pressure-bearing component includes an elastic anvil plate arranged on the opposite side of the slit cutting device. The auxiliary pressing structure includes a pressing strip and a driving telescopic component for driving the pressing strip to reciprocate linearly. The slit cutting device includes a drive frame, inside which two electric telescopic rods are installed symmetrically. The upper side of the drive frame is provided with a slit structure and the lower side is provided with a cutting structure. The sides of the slit structure and the cutting structure that are opposite to each other extend into the drive frame and are respectively engaged with the electric telescopic rods on the corresponding sides. The drive frame is further provided with symmetrically installed movable tracks and sliders that cooperate with the movable tracks. The surfaces of the two sliders are vertically connected with slit structures and cutting structures. The side surfaces of the two sliders are respectively connected with drive telescopic components fixed to the outside of the drive frame. The telescopic direction of the drive telescopic components is parallel to the extension direction of the movable tracks, so as to independently drive the two sliders to perform linear reciprocating motion along the movable tracks. The slit structure includes a first rotating rod vertically connected to a movable shaft seat integrally formed on the upper side of the slider. A first drive motor is connected to the end of the first rotating rod. An installation turntable is fixedly fitted on the first rotating rod. Limiting groove frames are evenly opened around the circumference of the installation turntable. A drive ring is provided at the center of the surface of the installation turntable. The drive ring is fitted and installed with the first rotating rod. Adjusting buckles are provided at positions corresponding to the limiting groove frames on the surface of the installation turntable. A drive rod connected to the surface of the installation turntable is provided on the side of the adjusting buckle. A fastening groove for installing an arc-shaped slit blade is opened on the other side of the adjusting buckle. A fastening plate adapted to the fastening groove is provided on the surface of the arc-shaped slit blade and locked and fixed by bolts. The adjusting buckle is a U-shaped structure and is sleeved on the side surface of the mounting turntable. An elastic connecting post is provided at the opening of the adjusting buckle. The elastic connecting post is located inside the limiting groove frame and moves in conjunction with the adjusting buckle.

[0006] Furthermore, the elastic pressure-bearing component includes a fixed plate, on the surface of which a movable air plate and an elastic anvil are sequentially mounted. The surface of the movable air plate is provided with a first protrusion and a first groove in a staggered manner. The elastic anvil is recessed inward on the side facing the movable air plate to form a mating groove frame. The mating groove frame is provided with a second protrusion and a second groove that can be fitted and matched with the first protrusion and the first groove.

[0007] Furthermore, the movable air plate has a hollow structure and is externally connected to an air blower, and the groove wall of the first groove is made of an elastic material.

[0008] Furthermore, the arc-shaped slitting blade adopts a micro-blunted arc-shaped blade structure, and the cutting edge is rounded.

[0009] Furthermore, the cutting structure includes a second rotating rod that is vertically mounted to the movable shaft seat located below the slider. A second drive motor is provided at the end of the second rotating rod. A rotating plate is sleeved on the surface of the second rotating rod. Support plates are equidistantly mounted on the outer surface of the rotating plate along the circumferential direction. A cutting blade is detachably mounted at the end of the support plate.

[0010] Furthermore, the cutting blade adopts a sharp, acute-angled blade structure; the arc-shaped slit blade only cuts into the surface resin of the carbon fiber prepreg, without cutting the internal carbon fiber bundles, and the cutting blade can completely cut the carbon fiber prepreg as a whole.

[0011] Furthermore, the drive telescopic component drives the pressure bar to press down and tighten the material strip, and the pressing action is linked in sequence with the cutting and slitting actions. The other end of the drive telescopic component is connected to a drive box.

[0012] By adopting the aforementioned technical solution, the beneficial effects of the present invention are: This invention integrates a slit cutting device, combining a shallow slit structure and a full-penetration cutting structure within the same drive frame. The device has a high degree of integration and a compact layout, solving the problems of separate cutting mechanisms, large space occupation, and poor process connection in traditional equipment, and significantly improving the continuity and stability of the laying and cutting process.

[0013] The arc-shaped cutting blade is equipped with a slightly blunted arc edge, which only cuts into the surface resin of the prepreg without cutting the internal carbon fiber bundles, effectively avoiding defects such as broken fibers, fuzzing, and pulling fibers; the cutting blade is equipped with a sharp, acute-angled edge, which can completely cut the prepreg as a whole, precisely matching the core process requirement of "first opening the slit and separating the fibers, and then cutting to a fixed length" in carbon fiber laying, thus greatly improving the molding quality. Specifically, this invention features an adjustable blade mounting structure. A U-shaped adjusting plate slides radially along the mounting turntable via a telescopic push-pull mechanism using a drive rod. An elastic connecting column is elastically positioned within a limiting slot, simultaneously driving the arc-shaped cutting blade to move radially, thereby adjusting the blade's extension length. By selecting different limiting slots along the circumference of the mounting turntable and assembling the adjusting plate and arc-shaped cutting blade, the circumferential installation spacing between adjacent blades can be changed, adapting to the cutting requirements of prepregs with different thicknesses and filament spacings. After adjustment, the blade position is fixed by bolting the fastening plate. This invention features an elastic pressure-bearing component and a time-linked auxiliary pressing structure. The elastic anvil, in conjunction with the movable air plate, achieves flexible pressure bearing. The pressing strip can tighten the material strip before cutting, effectively preventing the prepreg from slipping or shifting during the cutting process, ensuring uniform cuts and accurate cutting dimensions. At the same time, the hollow movable air plate can achieve air blowing for dust removal and anti-sticking, improving the continuous operation capability of the equipment. Attached Figure Description

Detailed Implementation

[0015] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0016] refer to Figure 1 - Figure 6 This embodiment provides a carbon fiber laying device, the structure of which includes a fixed base plate 1, a pressure regulating component 2 fixedly installed on the upper right side of the fixed base plate 1, a carbon fiber feeding tray 3 located on the left edge of the fixed base plate 1, a front feeding wheel 4 installed on the surface of the fixed base plate 1 and located near the pressure regulating component 2, a servo feeding mechanism 5 located behind the front feeding wheel 4 and having differential speed compensation function, a laying and cutting assembly 6 located behind the servo feeding mechanism 5, and a carbon fiber laying head 7 installed on the lower surface of the fixed base plate 1. A temperature detector 8 and an infrared heater 9 are provided on the rear side of the carbon fiber laying head 7. The laying and cutting assembly 6 includes an elastic pressure member 61 and a cutting device 63 arranged along the carbon fiber feeding direction. An auxiliary pressing structure 62 is provided on the side of the cutting device 63. The elastic pressure member 61 includes an elastic anvil 615 located on the opposite side of the cutting device 63. The auxiliary pressing structure 62 includes a pressing strip 623 and a drive telescopic member 622 for driving the pressing strip 623 to reciprocate linearly. The other end of the drive telescopic member 622 is connected to the drive box 621. The drive telescopic member 622 drives the pressing strip 623 to press down and tighten the material strip. The pressing action is linked with the cutting and slitting actions in sequence, effectively preventing the material strip from slipping or shifting during the cutting process. The slit cutting device 63 includes a drive frame 631. Inside the drive frame 631, two electric telescopic rods 633 are installed symmetrically. The upper side of the drive frame 631 is provided with a slit cutting structure 635 and the lower side is provided with a cutting structure 636. The opposite sides of the slit cutting structure 635 and the cutting structure 636 extend into the drive frame 631 and are respectively engaged with the electric telescopic rods 633 on the corresponding sides.

[0017] In this embodiment, the drive frame 631 is generally a rectangular frame structure, with two movable tracks 632 symmetrically arranged vertically inside. The two movable tracks 632 are fixedly installed on the front inner wall and the rear inner wall of the drive frame 631, respectively, and each movable track 632 extends horizontally along the width direction of the drive frame 631. A slider 634 is slidably installed on each movable track 632, with the two sliders 634 located in the upper and lower halves of the drive frame 631, respectively. The upper surface of the upper slider 634 has a movable shaft seat integrally formed thereon, used for vertically connecting the first rotating rod 6351 of the slit structure 635; the lower surface of the lower slider 634 has a movable shaft seat integrally formed thereon, used for vertically connecting the second rotating rod 6361 of the cutting structure 636. The side surfaces of the two sliders 634 (i.e., the vertical sides of the sliders facing the outside of the drive frame 631) are respectively fixedly connected to the telescopic ends of the drive telescopic component 622 by bolts or pins. The driving telescopic component 622 is a cylinder, hydraulic cylinder, or electric push rod. Its cylinder end is fixedly mounted on the external bracket or fixed base plate 1 of the drive frame 631, and its telescopic end extends horizontally into the drive frame 631 and is rigidly connected to the side surface of the corresponding slider 634. The telescopic direction of the driving telescopic component 622 is parallel to the extension direction of the movable track 632. When the driving telescopic component 622 extends or retracts, it drives the slider 634 to reciprocate linearly along the movable track 632, thereby independently controlling the horizontal feed displacement of the slit structure 635 and the cutting structure 636. The two sliders 634 do not interfere with each other and move independently, each driven independently by its corresponding driving telescopic component 622, achieving spatial separation and temporal linkage between the slit and cutting processes. With the independent feeding layout of "double slider - double track - double drive telescopic component", the cutting structure and the cutting structure can independently control the feed amount, feed speed and action sequence. This not only enables the cutting and cutting to be integrated in the same drive frame, but also allows them to complete their respective cutting actions without interference, thus improving the equipment's operational flexibility and process adaptability.

[0018] The elastic pressure-bearing component 61 includes a fixed plate 611. A movable air plate 612 and an elastic cutting board 615 are sequentially mounted on the surface of the fixed plate 611. The surface of the movable air plate 612 is provided with a first protrusion 613 and a first groove 614 in a staggered manner. The side of the elastic cutting board 615 facing the movable air plate 612 is recessed inward to form a mating groove frame 616. The mating groove frame 616 is provided with a second protrusion 617 and a second groove 618 that can be fitted and matched with the first protrusion 613 and the first groove 614. The installation stability of the elastic cutting board is improved by the concave-convex fitting structure. The movable air plate 612 is a hollow structure and is connected to an external air blower. Specifically, the interior of the movable air plate 612 is hollow to form a sealed cavity. The side of the cavity facing the elastic cutting board 615 is evenly and densely covered with several through-type micro air holes. The air blower continuously introduces compressed air into the hollow cavity. The airflow is evenly sprayed onto the cutting contact surface through the micro air holes to remove carbon powder and residual adhesive generated during cutting, thereby achieving anti-sticking and dust removal. The groove wall of the first groove 614 is made of elastic material. During or after the work is completed, the cutting area can be dusted and prevented from sticking by blowing air. At the same time, the elastic groove wall can adapt to flexible pressure deformation.

[0019] The slit structure 635 includes a first rotating rod 6351 that is vertically connected to a movable shaft seat that mates with the slider 634. The movable shaft seat is integrally formed on the upper surface of the slider 634. The first rotating rod 6351 is vertically inserted into and rotatable within the movable shaft seat. A first drive motor 6352 is connected to the end of the first rotating rod 6351. A mounting turntable 6353 is fixedly mounted on the first rotating rod 6351. Limiting grooves 6354 are evenly distributed around the circumference of the mounting turntable 6353. A drive ring 63 is provided at the center of the surface of the mounting turntable 6353. 55. The drive ring 6355 is fitted with the first rotating rod 6351. Adjustment buckles 6356 are provided on the surface of the mounting turntable 6353 at the positions corresponding to the limiting groove frame 6354. The side of the adjustment buckle 6356 is provided with a drive rod 6357 connected to the surface of the mounting turntable 6353. The other side of the adjustment buckle 6356 is provided with a fastening groove for installing the arc-shaped cutting blade 6359. The surface of the arc-shaped cutting blade 6359 is provided with a fastening plate 63510 that matches the fastening groove and is locked and fixed by bolts.

[0020] The adjusting plate 6356 has a U-shaped structure and is fitted onto the side surface of the mounting turntable 6353. An elastic connecting post 6358 is provided at the opening of the adjusting plate 6356. The elastic connecting post 6358 is located inside the limiting groove frame 6354 and moves in conjunction with the adjusting plate 6356, which can realize precise fine adjustment and elastic limiting of the blade position.

[0021] Specifically, the U-shaped adjusting buckle 6356 is pushed and pulled by the drive rod 6357 to slide radially along the mounting turntable 6353. The elastic connecting column 6358 is elastically limited in the limiting groove frame 6354, which synchronously drives the arc-shaped cutting blade 6359 to move radially, thereby adjusting the blade extension length. By selecting different limiting groove frames 6354 along the circumference of the mounting turntable 6353 to assemble the adjusting buckle 6356 and the arc-shaped cutting blade 6359, the circumferential installation distance of adjacent blades can be changed to adapt to the cutting requirements of prepregs with different thicknesses and filament spacing. After adjustment, the blade position is fixed by locking the fastening plate with bolts.

[0022] The 6359 arc-shaped slitting blade adopts a micro-blunted arc-shaped blade structure. The cutting edge is rounded and only cuts into the surface resin of the carbon fiber prepreg without cutting the internal carbon fiber bundles, achieving a non-destructive shallow slitting and filament separation effect.

[0023] The cutting structure 636 includes a second rotating rod 6361 that is vertically mounted to a movable shaft seat that mates with the lower surface of the slider 634. The movable shaft seat is integrally formed on the lower surface of the slider 634. The second rotating rod 6361 is vertically inserted into the movable shaft seat and can rotate. A second drive motor 6362 is provided at the end of the second rotating rod 6361. A rotating plate 6363 is sleeved on the surface of the second rotating rod 6361. Support plates 6364 are equidistantly mounted on the outer surface of the rotating plate 6363 along the circumferential direction. A cutting blade 6365 is detachably mounted at the end of the support plate 6364. The cutting blade 6365 adopts a sharp-angled blade structure and can completely cut the carbon fiber prepreg material, meeting the requirements of fixed-length cutting process.

[0024] The drive telescopic component 622 drives the pressure bar 623 to press down and tighten the material strip. The pressing action is linked to the cutting and slitting actions in sequence. The other end of the drive telescopic component 622 is connected to the drive box 621.

[0025] During operation, the carbon fiber feeding tray 3 releases the prepreg filaments, which are guided and conveyed by the front feeding wheel. The servo feeding mechanism 5 with differential speed compensation function stabilizes the feeding and eliminates conveying tension errors. The material belt is conveyed to the laying and cutting assembly 6 position. The drive box 621 drives the drive telescopic component 622 to drive the pressure bar 623 to press down and fix the material belt to prevent slippage. Then, the electric telescopic rod 633 cooperates with the slider 634 to feed along the movable track. The first drive motor 6352 drives the mounting turntable 6353 to rotate, which drives the circumferentially arranged micro-blunted arc-shaped cutting blades 6359 to roll and contact the prepreg, uniformly cutting shallow slits on the surface of the material belt to separate the filaments without cutting the carbon fiber filaments. After the single-segment cutting is completed, according to the laying length requirements, the second drive motor 6362 drives the rotating plate 6363 to rotate, which drives the sharp cutting blades 6365 to rotate at high speed to cut the prepreg as a whole. After the cutting is completed, all structures are reset, and the material belt continues to be conveyed. The cut material strip is conveyed to the carbon fiber laying head position. Temperature detector 8 monitors the temperature of the laying area in real time and links with infrared heater 9 to automatically adjust the heating temperature to ensure stable temperature during prepreg laying, bonding and curing, and finally complete the high-precision automated laying operation. At the same time, the movable air plate continuously blows air to remove carbon powder and residual adhesive from the cutting area to ensure continuous and stable operation of the equipment.

[0026] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which shall be within the scope of protection of the invention.
