Description

Technical Field

[0001] This utility model relates to the field of testing, and in particular to a carbon fiber testing device. Background Technology

[0002] Carbon fiber is a new type of composite material widely used in aerospace, carbon core cables, sports and leisure, pressure vessels, wind turbine blades, and other fields. Carbon fiber is drawn into carbon fiber filaments, which are then oxidized and carbonized to form carbon fiber yarns suitable for weaving. During the production processes of filament production, transfer, unwinding, and oxidation / carbonization, localized damage, breakage, and twisting of the carbon fiber filaments may occur, forming clumps and strands that adhere to the carbon fiber yarn.

[0003] Currently, the appearance inspection of carbon fiber yarn mainly involves evaluating the quality of the entire carbon fiber bobbin by observing surface defects after winding. This method can only detect external defects and cannot detect internal defects at all. Furthermore, it relies heavily on manual observation, which is affected by various factors such as mood and physical strength, resulting in subjective and inconsistent evaluations. At the same time, it cannot generate long-term quality data, making it difficult to guide production. Utility Model Content

[0019] The following will refer to the appendix. Figures 1 to 3 The present invention will be described in detail with reference to the embodiments.

[0020] Overall, this utility model proposes a carbon fiber detection device. The detection device is installed on one side of the carbon fiber spool winding position. The detection device includes a fixed plate 1, a side plate 101 fixedly disposed on one side of the fixed plate 1, a connecting plate 2 fixedly disposed on the top of the fixed plate 1, an extension plate 5 fixedly disposed on the front side of the connecting plate 2, and an L-shaped mounting plate 501 fixedly disposed on the front end of the shrinkage extension plate 5. The axis of the mounting plate 501 is parallel to the axis of the fixed plate 1. A camera 503 is fixedly disposed on the mounting plate 501, and the camera 503 faces the fixed plate 1. A first rotating shaft 4 is rotatably provided on the top front side of the connecting plate 2. A second rotating shaft 401 is rotatably provided on the right side below the first rotating shaft 4. A fourth rotating shaft 403 is rotatably provided on the side of the side plate 101 located on the front side of the fixing plate 1. A fifth rotating shaft 404 is rotatably provided on the side plate 101 located below and in front of the fourth rotating shaft 403. The carbon fiber is wound from above the first rotating shaft 4 to the right side of the first rotating shaft 4, extends to the left side of the second rotating shaft 401, then wound downwards to the lower side of the fourth rotating shaft 403, and finally extends to the upper side of the fifth rotating shaft 404 and wound into the carbon fiber filament spool.

[0021] In this embodiment, the carbon fiber detection device uses a camera 503 positioned directly over the path area traversed by the carbon fiber. During the carbon fiber winding process, it can capture real-time, clear images of the carbon fiber's appearance, detecting defects such as clumps, strands, breaks, and fractures that may exist on the carbon fiber surface. This improves the accuracy and comprehensiveness of the detection, avoids missed detections that may occur during manual inspection, and provides reliable assurance for the quality of carbon fiber products.

[0022] In addition, this device incorporates multiple rotating shafts, including a first rotating shaft 4, a second rotating shaft 401, a fourth rotating shaft 403, and a fifth rotating shaft 404. The carbon fiber is wound along these shafts along a specific path. This design not only maintains stable tension on the carbon fiber during winding, reducing quality issues caused by uneven tension, but also ensures that the carbon fiber is positioned at the appropriate angle and location when entering the detection area of ​​the camera 503. This guarantees that the camera 503 can acquire the optimal detection image, further improving the detection effect.

[0023] In practice, the carbon fiber detection device is installed on one side of the carbon fiber spool winding position, ensuring that all components are securely installed, and the camera 503 is facing the preset detection area. The parameters of the camera 503, such as focal length and exposure time, are adjusted to enable it to clearly and accurately capture images of the carbon fiber's appearance. The carbon fiber to be detected is introduced into the detection device. First, the carbon fiber is placed above the first rotating shaft 4, and then wound around to the right side of the first rotating shaft 4. At this time, the carbon fiber, guided by the first rotating shaft 4, begins to enter the winding path of the detection device. The carbon fiber extending from the right side of the first rotating shaft 4 enters the left side of the second rotating shaft 401 and winds downwards to the lower side of the second rotating shaft 401. During this process, the carbon fiber gradually enters the detection area facing the camera 503, and the camera 503 begins to capture images of the carbon fiber's appearance in real time, transmitting the image data to the subsequent image processing system. After passing the second rotating shaft 401, the carbon fiber continues to extend to the lower side of the fourth rotating shaft 403 on the side plate 101 and winds onto the fourth rotating shaft 403. The placement of the fourth shaft 403 and the fifth shaft 404 helps adjust the tension and orientation of the carbon fiber, ensuring its stability during winding. The carbon fiber extending from below the fourth shaft 403 eventually reaches above the fifth shaft 404 and is wound into the carbon fiber spool. During winding, the camera 503 captures and analyzes images.

[0024] Based on the above configuration, a sloping plate 405 is fixedly provided at the lower front side of the connecting plate 2. The sloping plate 405 is tilted forward and to the right. The side plate 101 of the sloping plate 405 is rotatably provided with a third rotating shaft 402. The third rotating shaft 402 is located between the second rotating shaft 401 and the fourth rotating shaft 403. The carbon fiber extends downward from the second rotating shaft 401 and wraps around one side of the third rotating shaft 402, and then extends downward to the third rotating shaft 402. The carbon fiber changes from being perpendicular to the fixed plate 1 to being parallel to the fixed plate 1.

[0025] As the carbon fiber passes the third rotating shaft 402, its position changes from perpendicular to the fixed plate 1 to parallel to it. This change allows the camera 503 to capture the appearance of the carbon fiber from a more suitable angle. When the carbon fiber is parallel to the fixed plate 1, the camera 503 can capture the details of the carbon fiber surface more comprehensively and clearly, avoiding blind spots caused by angle issues. For example, some tiny clumps or shallow scratches that are difficult to detect in a perpendicular state can be more clearly presented in the image of the camera 503 in a parallel state, greatly improving the accuracy and sensitivity of defect detection and helping to promptly identify and address potential quality problems.

[0026] Preferably, the inclined plate 405 is provided with a third sliding groove 4051, the third rotating shaft 402 is slidably connected in the third sliding groove 4051, and is fixed to the inclined plate 405 by screws. Different specifications of carbon fibers, such as those with different diameters and twists, require different optimal winding tensions and paths. The sliding design of the third rotating shaft 402 allows the testing device to easily adapt to the testing needs of various carbon fiber specifications. Operators only need to slide the third rotating shaft 402 to the appropriate position and fix it according to the specifications of the carbon fiber to adjust the winding path and tension distribution of the carbon fiber, without the need for large-scale modifications or replacement of parts in the testing device.

[0027] It should be noted that the connecting plate 2 has a second sliding groove 400 and / or the extension plate 5 has a fourth sliding groove 5011; the end of the first rotating shaft 4 is slidably connected in the second sliding groove 400 and fixed to the connecting plate 2 by screws; the end of the mounting plate 501 is slidably connected in the fourth sliding groove 5011 and fixed to the extension plate 5 by screws.

[0028] In this embodiment, the first rotating shaft 4 is slidable within the second groove 400 of the connecting plate 2, which allows for flexible adjustment of the initial position and angle of the carbon fiber entering the detection device. Different batches or specifications of carbon fiber have different initial tensions and winding characteristics. By sliding the first rotating shaft 4, the winding angle and force point of the carbon fiber at the first rotating shaft 4 can be changed, thereby controlling the tension of the carbon fiber when it enters the subsequent winding path.

[0029] In addition, by adjusting the position of the mounting plate 501, the camera 503 can be aligned with the carbon fiber at the optimal angle and distance, ensuring that defects on the carbon fiber surface can be captured clearly and comprehensively. Whether it is a tiny tuft or a shallow scratch, it can be accurately detected, improving the accuracy and reliability of the detection.

[0030] Preferably, a rear plate 3 is located on the lower rear side of the connecting plate 2. A controller 301, which is communicatively connected to the camera 503, is fixedly mounted on the rear plate 3. The rear plate 3 has a first sliding groove 302 that is slidably connected to the connecting plate 2, and the rear plate 3 is fixed to the connecting plate 2 by screws. The controller 301 contains an image processing module, which can refer to existing image processing and recognition systems. Based on the defect information fed back by the controller 301, the operator stops the winding of the carbon fiber and marks and processes the problematic carbon fiber.

[0031] The description further clarifies that a light source 502 for illumination is fixedly mounted on the top of the camera 503. This light source 502 provides sufficient and uniform light to the detection area, effectively eliminating shadows and reflections. The surface of carbon fiber is relatively smooth, and it is prone to reflection under different angles of light, resulting in bright spots or dark areas in the image, affecting the camera 503's ability to identify surface defects. The light source 502 can illuminate the carbon fiber surface at a specific angle and intensity, ensuring uniform light distribution and allowing the camera 503 to capture every detail of the carbon fiber surface.

[0032] A white-gray background plate 6 is fixedly mounted on the front side of the mounting plate 1, with the camera 503 facing the background plate 6. The white-gray background plate 6 provides a uniform and stable background for the carbon fiber. Carbon fiber is typically dark in color, creating a sharp contrast with the white-gray background, allowing the camera 503 to more clearly capture subtle changes on the carbon fiber surface. For example, when defects such as clumps or streaks exist on the carbon fiber surface, these defects become more prominent against the dark carbon fiber and white-gray background, making it easier for the camera 503 to identify the shape, size, and location of the defects, significantly improving the accuracy and sensitivity of defect detection.

[0033] In addition, the carbon fiber end winding process involves left and right movement to prevent the spool from becoming too thick or too thin in certain areas. To accommodate the left and right movement of the carbon fiber, the connecting plate 2 is fixedly mounted on the drag chain 7, which in turn moves the device to ensure the readiness of the test.

[0034] Use appropriate fixing methods to fix the connecting plate 2 to the cable chain 7 according to the actual situation. Common fixing methods include bolt connection, snap-on connection, etc.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
