Abstract
Description
Technical Field
[0001] This application relates to the field of carbon fiber production equipment, and in particular to a carbon fiber extraction device. Background Technology
[0002] Automated cutting and layup technology for carbon fiber prepregs is widely used in aerospace, wind turbine blades, and automotive lightweighting. Traditional processes require cutting prepregs into specific shapes (such as strips or sheets) and laying them layer by layer into a mold according to a designed angle and sequence to form a composite material laminate structure. The accuracy and efficiency of this layup directly affect the mechanical properties and manufacturing cost of the final product.
[0003] Currently, the mainstream equipment uses a fixed worktable. After the carbon fiber strips are cut, they need to be picked up manually or by a robotic arm and placed in a fixed position. When multiple pieces of material need to be laid continuously or multiple layers need to be stacked, the manual method is less efficient. When the robotic arm is used for laying, after each laying, the robotic arm needs to return to the cutting area to pick up the material. If the mechanic moves horizontally and then vertically to the new laying point, such multi-directional and long-distance back-and-forth movements greatly reduce production efficiency. If the robotic arm moves diagonally to the new laying point, it is easy to cause the carbon fiber to be laid crookedly.
[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

The clamping mechanism is used to clamp the end of the carbon fiber strip cut by the cutting device. The robotic arm is used to drive the clamping mechanism to make linear reciprocating motion along a second direction, so that the carbon fiber strip moves above the substrate. The second direction is perpendicular to the first direction.
[0015] In some embodiments, the displacement driving mechanism includes a servo motor, a lead screw module, a guide rail, a slider, and a base; the servo motor is mounted on the base and is connected to the lead screw module in a transmission manner; the nut of the lead screw module is connected to the bottom of the substrate; the guide rail is fixedly mounted on the base and extends along the first direction; the slider is fixedly mounted on the bottom of the substrate and is slidably connected to the guide rail.

The yarn eyelet disc is provided with a plurality of yarn eyelets with different inner diameters. When the yarn eyelet disc is fixedly mounted on the guide rod by the locking bolt, at least one of the yarn eyelets is exposed on the guide rod, and the yarn eyelet located on the guide rod adjacent to the cutting device is opposite to the position of the clamping mechanism.
[0019] In some embodiments, a prepreg tank is provided between the guide rods, and a guide roller assembly is provided in the prepreg tank.
[0020] In some embodiments, the cutting device is a thermal cutting device or an ultrasonic cutting device.
[0021] (III) Beneficial Effects
[0022] Compared with the prior art, the beneficial effects of the technical solution provided in this application include at least the following:
[0023] When the carbon fiber extraction device of this application is in operation, the carbon fiber roll is mounted on the spool of the feeding device and the roll is continuously fed to the cutting device at the rear end; the clamping mechanism at the end of the robotic arm of the extraction device clamps the end of the carbon fiber strip; the robotic arm moves linearly along the second direction, and the movement stroke is the predetermined length of the carbon fiber strip; the cutting device cuts the roll into carbon fiber strips of predetermined length; the robotic arm precisely moves the carbon fiber strip from the cutting station to above the substrate; the substrate moves linearly along the first direction through the bottom displacement drive mechanism and is adjusted to the target laying position; the clamping mechanism releases the carbon fiber strip and lays the carbon fiber strip at the designated position on the substrate; then the process is repeated, the substrate moves along the X-axis to the next laying point, the robotic arm returns to the cutting area to pick up a new carbon fiber strip and moves along the Y-axis to lay it.
[0024] The carbon fiber extraction device of this application improves efficiency in layup operations. In traditional methods, the robotic arm needs to move a long distance diagonally to a new layup point, such as moving laterally first and then longitudinally; this path is not only long but also time-consuming. The robotic arm of this application is only responsible for short-distance reciprocating movement along the Y-axis, from the cutting area to the substrate area, with a fixed and efficient path. Simultaneously, the substrate independently undertakes the X-axis positioning task through a displacement drive mechanism, so that the robotic arm can perform material picking operations synchronously while the substrate moves. This effectively eliminates the long-distance diagonal or bidirectional movement of the robotic arm, thereby shortening the single layup cycle and improving operational efficiency.
[0025] The robotic arm of the carbon fiber extraction device in this application moves perpendicularly to the substrate, forming a rectangular coordinate system. In this way, the carbon fiber strip is always pulled linearly along the Y-axis by the robotic arm, while the substrate is positioned linearly along the X-axis, without interference from oblique paths. Therefore, the laying angle of the carbon fiber strip can be precisely controlled, avoiding skewed laying caused by tilted movement trajectories.
[0026] Equally important, the displacement drive mechanism can control the step distance of the substrate's movement along the X-axis. After each layup is completed, the substrate automatically moves to the next position, while the robotic arm only needs to repeat the fixed Y-axis pick-and-place action. This makes the carbon fiber extraction device of this application suitable for scenarios with multiple parallel layups or multi-layer stacking, thereby improving the layup efficiency.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0043] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.
[0044] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0045] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.
[0046] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.
[0047] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values that would be recognized by one of ordinary skill in the art.
[0048] The carbon fiber strips cut by existing carbon fiber extraction equipment need to be picked up manually or by a robotic arm and placed in a fixed position. When multiple sheets of material need to be laid continuously or multiple layers need to be stacked, the manual method is less efficient. When the robotic arm is used for laying, it needs to return to the cutting area to pick up the material after each laying. If the mechanic moves horizontally and then vertically to the new laying point, such multi-directional and long-distance back-and-forth movement greatly reduces production efficiency. If the robotic arm moves obliquely to the new laying point, it is easy to cause the carbon fiber to be laid crookedly.
[0049] To address the aforementioned technical problems, this embodiment provides a carbon fiber extraction device.
[0050] Figure 1 This is a front structural diagram of the carbon fiber extraction device in an embodiment of this application. Figure 2 This is a top view of the carbon fiber extraction device in an embodiment of this application.
[0051] See Figure 1 and Figure 2 As shown, the carbon fiber extraction device provided in this embodiment includes: a winding device 100, a cutting device 200, a substrate 300, a displacement driving mechanism 400, and an extraction device 500.
[0052] The winding device 100 includes a spool 110 for holding carbon fiber rolls. The spool 110 is rotatably mounted on a frame 120. The spool 110 can be a drive shaft driven by a power source or a passive shaft without a power source.
[0053] The cutting device 200 is located downstream of the winding device 100 along the conveying direction of the carbon fiber roll, and is used to cut the carbon fiber roll to obtain carbon fiber strips. The cutting device 200 can be an existing thermal cutting device or an ultrasonic cutting device, such as controlling the lifting of the cutter through a lifting mechanism to achieve the carbon fiber cutting operation.
[0054] The substrate 300 is used to support the carbon fiber strip and move along the first direction 800.
[0055] The displacement driving mechanism 400 is disposed at the bottom of the substrate 300 and is used to drive the substrate 300 to move linearly back and forth along the first direction 800.
[0056] An extraction device 500, disposed between the cutting device 200 and the substrate 300, includes a robotic arm 510 and a clamping mechanism 520 mounted at the end of the robotic arm 510. The clamping mechanism 520 is used to clamp the end of the carbon fiber strip cut by the cutting device 200. The clamping mechanism 520 is a pneumatic gripper 521 or an electric gripper. The robotic arm 510 is used to drive the clamping mechanism 520 to perform linear reciprocating motion along a second direction 900, so that the carbon fiber strip moves above the substrate 300. The second direction 900 is perpendicular to the first direction 800.
[0057] Figure 3 This is a perspective view of the substrate and displacement driving mechanism in the embodiments of this application.
[0058] See Figure 1 and Figure 3 As shown, the displacement drive mechanism 400 includes a servo motor 410, a lead screw module 420, a guide rail 430, a slider 440, and a base 450. The servo motor 410 is mounted on the base 450 and is connected to the lead screw module 420 through a suitable connection method (such as a coupling). The nut of the lead screw module 420 is connected to the bottom of the base plate 300 so as to convert the rotational motion of the servo motor 410 into the linear motion of the base plate 300. The guide rail 430 is fixedly mounted on the base 450 and extends along the first direction 800. The slider 440 is fixedly mounted on the bottom of the base plate 300 and is slidably connected to the guide rail 430, thereby ensuring that the base plate 300 can move linearly back and forth along the guide rail 430 and remain stable during the movement.
[0059] See Figure 1 and Figure 3 As shown, the base 450 is further provided with a rotary table 460 that can rotate around a vertical axis. The servo motor 410, the lead screw module 420, and the guide rail 430 are all mounted on this rotary table 460. The rotary table 460 can use an existing indexing rotary table. The rotary table 460 enables the entire displacement drive mechanism 400 and the base plate 300 to rotate around the vertical axis, thereby adjusting the angular position of the base plate 300. Combined with the action of the extraction device 500 pulling up the carbon fiber strip, the laying angle of the carbon fiber strip on the base plate 300 can be adjusted to achieve a more complex laying method between the carbon fiber strips.
[0060] Figure 4 This is a perspective view of the guide component in the embodiments of this application.
[0061] See Figure 1 and Figure 4As shown, to improve the accuracy and stability of carbon fiber feeding before cutting and to adapt to the feeding of carbon fiber bundles of different sizes, the carbon fiber extraction device also includes a guide assembly 600. The guide assembly 600 is disposed between the cutting device 200 and the winding device 100. The guide assembly 600 includes two guide rods 610 adjacent to the cutting device 200 and the winding device 100. The guide rods 610 are rotatably provided with a yarn eye plate 620 and a locking bolt 630 for fixing the position of the yarn eye plate 620. The yarn eye plate 620 is provided with a plurality of yarn eye holes 640 with different inner diameters. When the yarn eye plate 620 is fixedly mounted on the guide rods 610 by the locking bolts 630, at least one yarn eye hole 640 is exposed on the guide rods 610, and the yarn eye hole 640 of the guide rod 610 adjacent to the cutting device 200 is opposite to the position of the clamping mechanism 520. The mesh disc 620 has several mesh holes 640 with different inner diameters to guide the transmission path of carbon fiber rolls of different sizes, ensuring that they enter the cutting device 200 in a predetermined direction and angle and are gripped by the clamping mechanism 520. When it is necessary to change the mesh holes 640 to accommodate the size of the carbon fiber rolls to be processed, simply loosen the locking bolt 630, rotate the mesh disc 620 to expose the mesh hole 640 of the corresponding size, and then tighten the locking bolt 630. The adjustment operation is convenient.
[0062] See Figure 1 and Figure 2 As shown, a prepreg tank 700 is further provided between the guide rods 610, and a guide roller assembly 710 is provided within the prepreg tank 700. The design of the prepreg tank 700 ensures that the carbon fiber roll maintains appropriate tension and shape during transport, while also facilitating the prepreg treatment of the carbon fiber (if necessary). The specific configuration and quantity of the guide roller assembly 710 can be adjusted and optimized according to actual needs.
[0063] In this embodiment, when the carbon fiber extraction device is working, the carbon fiber roll is mounted on the roll 110 of the feeding device 100, and the roll is continuously fed to the cutting device 200 at the rear end. The clamping mechanism 520 at the end of the robotic arm 510 of the extraction device 500 clamps the head of the carbon fiber. The robotic arm 510 moves linearly along the second direction 900, and the moving distance is the predetermined length of the carbon fiber strip. The cutting device 200 cuts the roll into carbon fiber strips of the predetermined length. The robotic arm 510 precisely moves the carbon fiber strip from the cutting station to above the substrate 300. At the same time, the substrate 300 moves linearly along the first direction 800 through the bottom displacement driving mechanism 400 and is adjusted to the target laying position. The clamping mechanism 520 releases the carbon fiber strip and lays the carbon fiber strip at the designated position on the substrate 300. Then the process is repeated. The substrate 300 moves along the X-axis to the next laying point, and the robotic arm 510 returns to the cutting area to pick up a new carbon fiber strip and moves along the Y-axis to lay it.
[0064] The carbon fiber extraction device of this embodiment improves efficiency in the laying operation. In conventional methods, the robotic arm 510 needs to move a long distance diagonally to the new laying point, such as moving laterally first and then longitudinally. This path is not only long but also time-consuming. In this embodiment, the robotic arm 510 is only responsible for short-distance reciprocating movement on the Y-axis, from the cutting area to the substrate 300 area, and its path is fixed and efficient. At the same time, the substrate 300 independently undertakes the X-axis positioning task through the displacement drive mechanism 400, so that the robotic arm 510 can perform material picking operations synchronously when the substrate 300 moves. This effectively eliminates the long-distance diagonal movement or bidirectional movement of the robotic arm 510, thereby shortening the single laying cycle and improving work efficiency.
[0065] In this embodiment, the movement directions of the robotic arm 510 and the substrate 300 of the carbon fiber extraction device are perpendicular to each other, forming a rectangular coordinate system. Thus, the carbon fiber strip is always pulled linearly along the Y-axis by the robotic arm 510, while the substrate 300 is positioned linearly along the X-axis, without interference from oblique paths. Therefore, the laying angle of the carbon fiber strip can be precisely controlled, avoiding skewed laying caused by tilted movement trajectories.
[0066] Equally important, the displacement drive mechanism 400 can control the movement step of the substrate 300 along the X-axis. After each layup is completed, the substrate 300 automatically moves to the next position, while the robotic arm 510 only needs to repeat the fixed Y-axis pick-and-place action. This makes the carbon fiber extraction device of this embodiment suitable for scenarios with multiple parallel layups or multi-layer stacking, thereby improving the layup efficiency.
