Description

Technical Field

[0001] This invention relates to the field of new material testing technology, specifically to a device for detecting surface defects in a novel composite carbon fiber material. Background Technology

[0002] With its high specific strength and fatigue resistance, composite new carbon fiber materials have become an indispensable key material in high-end manufacturing fields such as aerospace and new energy vehicles. As the proportion of carbon fiber composite materials in load-bearing structural components continues to increase, their surface quality is directly related to the mechanical properties and service life of the components. High-precision and high-efficiency detection of surface defects in composite new carbon fiber materials has become an indispensable key link in the quality control system of new materials. For example, the patent with announcement number CN223107667U discloses a device for detecting surface defects in carbon fiber fabrics. The workbench is fixedly connected to a support block inside. A moving mechanism is connected to the side of the support block. A lifting mechanism is connected to one side of the moving mechanism. An industrial camera is connected to one side of the lifting mechanism. A support leg is provided on one side of the workbench. A winding mechanism is connected to one side of the support leg. The moving mechanism includes a first motor. The first motor and the support block are fixedly connected. A first rotating shaft is provided at the output end of the first motor. A first gear is fixedly connected to one side of the first rotating shaft. For example, the patent with publication number CN119246517A discloses a textile defect detection system, which relates to the field of textile defect detection technology. In the process of collecting external defect parameters, by collecting the number of fuzz balls, color difference value, and area of ​​color difference, it is beneficial to comprehensively evaluate the appearance quality of textiles. Collecting the number of fuzz balls can accurately identify the pilling phenomenon on the surface of textiles. The presence of fuzz balls will affect the overall appearance and service life of the fabric. The measurement of color difference value can reveal the unevenness of textiles in the dyeing process. The statistics of the area of ​​color difference can determine the severity of the color difference problem. For example, the patent with announcement number CN210863573U describes a surface defect detection system for bias-cut materials. This system is a defect detection device that includes a conveying unit, a detection unit, and a control unit for conveying the belt layer in the process. The conveying unit includes a conveyor belt and a servo motor. The detection unit includes multiple line scan camera detection devices. The control unit includes an industrial computer, an encoder, and a conveying control device. In the previous process, the line scan camera detects defects on the upper and lower surfaces of the belt layer. In the subsequent process, after the belt layer is edge-wrapped, the line scan camera detects defects on the edge-wrapping of the belt layer. This effectively completes the defect detection of the tire belt layer with high accuracy. Most of the aforementioned existing technologies improve the overall structure. However, while machine vision inspection improves the detection efficiency to some extent, the detection accuracy of existing composite carbon fiber material surface defect detection devices largely depends on the surface condition of the material being inspected. If the material is not fully stretched and flattened during the inspection process, surface wrinkles, curling, or local overlap will seriously interfere with the image acquisition quality, causing defect areas to be obscured or misjudged. The lack of auxiliary traction for the material during the stretching process makes the material prone to drooping or loosening, further affecting the comprehensiveness and accuracy of the inspection, thus resulting in certain limitations in its use. Summary of the Invention

[0003] The purpose of this invention is to provide a novel composite carbon fiber material surface defect detection device to address the problem mentioned in the background art that, although machine vision detection improves detection efficiency to a certain extent, its detection accuracy largely depends on the surface state of the material being detected. If the material is not sufficiently stretched and flattened during the detection process, surface wrinkles, curling, or local overlap will seriously interfere with the image acquisition quality, leading to the obscuring or misjudgment of defect areas. Furthermore, the lack of auxiliary traction for the middle section of the material during the stretching process makes it prone to drooping or loosening in the middle section, further affecting the comprehensiveness and accuracy of the detection.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a novel composite carbon fiber material surface defect detection device, comprising a base, a dual-axis drive motor installed on the inner side of the base, and a screw assembly connected to the output end of the dual-axis drive motor; a guide bearing member nested on the inner side of the base, with the lower end of the guide bearing member threadedly connected to the screw assembly; a docking motor assembly installed on the outer side of the upper end of the guide bearing member, with the output end of the docking motor assembly connected to a telescopic sleeve connecting shaft; a movable reserved part installed on the outer side of the end of the telescopic sleeve connecting shaft, with the surface of the movable reserved part bearing the material to be tested; and an extended precision measurement structure provided between the bases, through which the material to be tested is subjected to all-round detection processing.

[0005] Furthermore, the extended precision measurement structure is provided with a guide fitting, which is nested and connected to the inner side of the lower end of the base. The inner side of the lower end of the base is bonded to a built-in liquid bladder assembly, and the outer side of the built-in liquid bladder assembly corresponds to the outer side of the guide fitting. The upper end of the built-in liquid bladder assembly is provided with a supply corrugated elastic hose, which runs along the inner side of the base.

[0006] Furthermore, the lower end of the base is connected to a first vertical corrugated liquid bladder assembly, and the lower end of the first vertical corrugated liquid bladder assembly is connected to an upper limiting member. The first vertical corrugated liquid bladder assembly is connected to the end of the supply corrugated elastic hose. The inner side of the movable reserved member is nested with a lower limiting member, and the inner side of the lower limiting member is connected to a guide reserved steel rope assembly. The guide reserved steel rope assembly passes through the inner side of the movable reserved member, and the end of the guide reserved steel rope assembly is connected to the lower end of the upper limiting member.

[0007] Furthermore, when the lower end of the guide bearing moves to contact the guide fitting, it applies pressure to it, and the guide fitting squeezes the contacting built-in liquid bladder assembly. The built-in liquid bladder assembly supplies work to the first vertical corrugated liquid bladder assembly through the supply corrugated elastic hose, and the vertically expanded first vertical corrugated liquid bladder assembly pushes the docking upper limiting member to move downward along the outside of the movable reserved member.

[0008] Furthermore, when the upper limiting member moves downward, it drives the lower limiting member to form a traction operation through the guide reserved steel rope assembly, and the lower limiting member moves upward along the outside of the movable reserved member.

[0009] Furthermore, a guide contact structure is provided on the outer side of the telescopic sleeve connecting shaft, which vertically increases the extension range of the workpiece being inspected; the guide contact structure is provided with a supply hose, and the supply hose is connected to the inside of the first vertical corrugated liquid bladder assembly, and the inside of the telescopic sleeve connecting shaft is connected to a second vertical corrugated liquid bladder assembly, and the second vertical corrugated liquid bladder assembly and the supply hose are interconnected.

[0010] Furthermore, the upper end of the second vertical corrugated liquid bladder assembly is connected to an abutting rotating member, and the abutting rotating member is rotatably connected inside the telescopic sleeve connecting shaft, and a detection guide assembly is installed on the upper end of the base.

[0011] Furthermore, the first vertical corrugated liquid bladder assembly supplies power to the interior of the second vertical corrugated liquid bladder assembly via a supply hose, and the second vertical corrugated liquid bladder assembly expands vertically along the inner side of the telescopic sleeve connecting shaft.

[0012] Furthermore, during the vertical expansion of the second vertical corrugated liquid bladder assembly, pressure is applied to the contacting rotating component, and the contact rotating component rotates upward along the inner side of the telescopic sleeve connecting shaft, eliminating the detection blind zone existing in single-sided detection, and performing multi-sided detection processing while locking the material end side.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This novel composite carbon fiber material surface defect detection device is equipped with an extended precision measurement structure. The extended precision measurement structure performs all-round detection of the material to be tested. The whole device is driven by a screw assembly to move two guide bearings in opposite directions synchronously. During the process of the material extending to both sides, the lower end of the guide bearing 4 applies pressure to the built-in liquid bladder assembly through the guide fitting component. By supplying liquid to the corrugated elastic hose, the first vertical corrugated liquid bladder assembly moves vertically to push the upper limiting component downward, realizing dynamic self-limiting of one side of the material. This, in conjunction with the moving reserved component, evenly extends the material sample to both sides, so that the material surface is fully unfolded and wrinkles are eliminated. This ensures that all kinds of defects on and near the material surface are fully exposed within the detection field of view, effectively avoiding the problem of defect obscuring and missed detection caused by material curling or overlapping. Furthermore, when the upper limiting component moves downward along the outer side of the movable reserved component, the guide reserved steel rope assembly that is connected to it will be pulled by force, thereby driving the lower limiting component to move upward along the outer side of the movable reserved component. Together with the upper limiting component, it forms an auxiliary locking structure that works in conjunction with the upper limiting component. Its linkage locking mechanism ensures that the material always maintains a stable tension state during the extension process, effectively preventing the material from rebounding, loosening or shifting, and ensuring the continuous stability of subsequent testing procedures. Furthermore, a guiding contact structure is provided, which vertically increases the extension range of the workpiece being inspected. While the first vertical corrugated liquid bladder assembly with deformation negative pressure completes the locking action, it simultaneously supplies liquid to the second vertical corrugated liquid bladder assembly on the outer surface of the telescopic sleeve connecting shaft through the supply hose. This vertically pushes the contact rotating part upward, applying a vertical contact traction force to the middle section of the material in the extended state. This prevents defects such as sag and looseness from easily occurring in the middle section of the material, ensuring that the material is subjected to uniform force and fully extended throughout the entire width, greatly improving the extension efficiency and inspection accuracy. Furthermore, after the overall device completes the locking and extension of the material, the docking motor assembly connected to the telescopic sleeve connecting shaft can be driven to reciprocate 180°. This, in conjunction with the overall locking structure, can drive the material to rotate and flip on both sides, enabling the testing equipment to perform a comprehensive scan and identification of both sides of the material. This eliminates the blind spots in single-sided testing, and performs multi-sided testing while locking the material end side. This achieves all-round, no-dead-angle testing of surface defects in carbon fiber materials, significantly improving the comprehensiveness and reliability of the testing. Attached Figure Description

[0016] 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.

[0017] Example 1: Please refer to Figures 1-10This invention provides the following technical solution: a novel composite carbon fiber material surface defect detection device. To address the problem that while machine vision inspection improves detection efficiency to some extent, its accuracy largely depends on the surface state of the material being inspected. If the material is not sufficiently stretched and flattened during inspection, surface wrinkles, curling, or local overlap will severely interfere with image acquisition quality, leading to the obscuring or misjudgment of defect areas. Furthermore, the lack of auxiliary traction for the middle section of the material during stretching causes it to easily sag or loosen, further affecting the comprehensiveness and accuracy of the inspection. The device discloses a device including: a base 1... A dual-axis drive motor 2 is installed on the inner side, and the output end of the dual-axis drive motor 2 is connected to a screw assembly 3; a guide bearing 4 is nested on the inner side of the base 1, and the lower end of the guide bearing 4 is threadedly connected to the screw assembly 3; a docking motor assembly 7 is installed on the outer side of the upper end of the guide bearing 4, and the output end of the docking motor assembly 7 is connected to a telescopic sleeve connecting shaft 6; a movable reserved part 5 is installed on the outer side of the end of the telescopic sleeve connecting shaft 6, and the surface of the movable reserved part 5 carries the material to be tested; an extended precision measurement structure is set between the bases 1, and the material to be tested is subjected to all-round testing through the extended precision measurement structure.

[0018] The extended precision measurement structure is provided with a guide fitting 8, which is nested and connected to the lower inner side of the base 1. The lower inner side of the base 1 is bonded to a built-in liquid bladder assembly 9, and the outer side of the built-in liquid bladder assembly 9 corresponds to the outer side of the guide fitting 8. A supply corrugated elastic hose 10 is provided through the upper end of the built-in liquid bladder assembly 9, and the supply corrugated elastic hose 10 passes through the inner side of the base 1. The lower end of the base 1 is connected to a first vertical corrugated liquid bladder assembly 11, and the lower end of the first vertical corrugated liquid bladder assembly 11 is connected to an upper limiting member 12. The first vertical corrugated liquid bladder assembly 11 and the end of the supply corrugated elastic hose 10 are connected to each other.A lower limiting member 14 is nested inside the movable reserved part 5, and a guide reserved steel rope assembly 13 is connected to the inner side of the lower limiting member 14. The guide reserved steel rope assembly 13 passes through the inner side of the movable reserved part 5, and the end of the guide reserved steel rope assembly 13 is connected to the lower end of the upper limiting member 12. When the lower end of the guide bearing member 4 moves to contact the guide fitting member 8, it applies pressure to it, and the guide fitting member 8 squeezes the contacting built-in liquid bladder assembly 9. The built-in liquid bladder assembly 9 is supplied to the first vertical corrugated liquid bladder assembly 11 through the supply corrugated elastic hose 10. The vertically expanding first vertical corrugated liquid bladder assembly 11 pushes the connected upper limiting member 12 downward along the outer side of the movable reserved part 5. When the upper limiting member 12 moves downward, it drives the lower limiting member 14 to form a traction operation through the guide reserved steel rope assembly 13. The lower limiting member 14 moves upward along the outside of the movable reserved member 5. After the carbon fiber composite material of the rigid material to be tested is placed on the surface of the two movable reserved members 5, the screw assembly 3 drives the two guide bearing members 4 to move synchronously in opposite directions. During the process of the material extending to both sides, the lower end of the guide bearing member 4 applies pressure to the built-in liquid bladder assembly 9 through the guide fitting member 8. By supplying liquid to the corrugated elastic hose 10, the first vertical corrugated liquid bladder assembly 11 moves vertically to push the upper limiting member 12 downward, realizing dynamic self-limitation of the material on one side, thereby cooperating with the movable reserved member 5 to move the material sample to be tested. The material extends evenly to both sides, fully unfolding the surface and eliminating wrinkles, ensuring that all defects on and near the surface are fully exposed within the inspection field of view. As the upper limiting member 12 moves downwards along the outer side of the movable reserved member 5, the guide reserved steel rope assembly 13 connected to it will be pulled by force, thereby driving the lower limiting member 14 to move upwards along the outer side of the movable reserved member 5. This, in conjunction with the upper limiting member 12, forms an auxiliary locking structure with upper and lower cooperation. Its linkage locking mechanism ensures that the material maintains a stable tension state throughout the extension process, effectively preventing material rebound, slackness, or displacement, thus guaranteeing the continuous stability of subsequent inspection procedures. After the material is fully extended, locked, and kept flat, the device activates the inspection guide assembly 18. A high-resolution linear scan camera detection guide assembly 18, positioned directly above the material, is paired with a multi-angle external combined light source to continuously scan the material surface line by line. By adjusting the angle and brightness of the light source, different types of defects, such as microcracks, delamination, pores, and resin-rich / resin-poor materials, are made to form significant grayscale contrasts under specific lighting conditions. The raw image data acquired by the camera of the detection guide assembly 18 is transmitted at high speed to an image processing industrial control computer, where it is processed in real time by a built-in defect detection algorithm, including image enhancement, edge sharpening, threshold segmentation, and a deep learning-based semantic segmentation model. The algorithm automatically extracts the geometric features of the defect area, including length, width, area, and shape, and classifies and labels them. At the same time, in conjunction with an encoder, the horizontal and vertical position information of the material is recorded synchronously to accurately locate the coordinates of each defect.After a single-sided scan is completed, the flipping mechanism rotates the material 180° so that the back side is presented to the camera's field of view under the same tension. This scanning and recognition process is repeated, thereby achieving high-precision online defect detection and data archiving of both sides of the carbon fiber material.

[0019] Example 2: Based on Example 1, a guiding resistance structure is also disclosed, the specific structure of which is as follows: A guide contact structure is provided on the outer side of the telescopic sleeve connecting shaft 6, which vertically increases the extension range of the workpiece being inspected. The guiding contact structure is equipped with a supply hose 15, which is connected to the inside of the first vertical corrugated liquid bladder assembly 11. A second vertical corrugated liquid bladder assembly 16 is connected to the inside of the telescopic sleeve connecting shaft 6, and the second vertical corrugated liquid bladder assembly 16 is interconnected with the supply hose 15. An abutment rotating member 17 is connected to the upper end of the second vertical corrugated liquid bladder assembly 16, and the abutment rotating member 17 is rotatably connected to the inside of the telescopic sleeve connecting shaft 6. A detection guide assembly 18 is installed on the upper end of the base 1. The first vertical corrugated liquid bladder assembly 11 supplies power to the inside of the second vertical corrugated liquid bladder assembly 16 through the supply hose 15. The second vertical corrugated liquid bladder assembly 16 expands vertically along the inner side of the telescopic sleeve connecting shaft 6. During the vertical expansion of the second vertical corrugated liquid bladder assembly 16, pressure is applied to the contacting abutment rotating member 17, and the abutment rotating member 17 moves along the telescopic sleeve connecting shaft 6. As the inner side of shaft 6 rotates upward, the first vertical corrugated liquid bladder assembly 11, which deforms under negative pressure, completes its locking action. Simultaneously, it supplies liquid through the supply hose 15 to the second vertical corrugated liquid bladder assembly 16 on the outer surface of the telescopic sleeve connecting shaft 6. This vertically pushes the resisting rotating part 17 upward, applying a vertical resisting traction force to the middle end of the material in its extended state. This prevents the material from easily sag or loosening in the middle section, ensuring that the material is subjected to uniform force across its entire width. After the entire device completes the locking and extension of the material, the docking motor assembly 7, which is connected to the telescopic sleeve connecting shaft 6, can be driven to perform a 180° reciprocating rotation. This, in conjunction with the overall locking structure, allows the material to rotate and flip on both sides, enabling the detection equipment to perform a comprehensive scan and identification of both sides of the material. This eliminates the detection blind spots present in single-sided detection, allowing for multi-sided detection processing while locking the material end side.
