Description

Technical Field

[0001] This utility model belongs to the field of cable surface defect detection technology, and in particular relates to a cable detection device. Background Technology

[0002] Cable testing devices are used to inspect the surface quality of cables. In existing technology, when a cable is placed into the testing device, it must be inserted into the testing hole, which requires cutting the cable before insertion. However, this interrupts cable production, making the existing testing device unusable on a cable production line and causing discontinuity in cable production. Summary of the Invention

[0003] The purpose of this invention is to provide a cable testing device that addresses the problems of existing technologies by allowing cables to be placed into the testing device for defect detection without being cut. It can also be used in conjunction with cable production lines to achieve seamless integration of cable production and quality inspection.

[0004] To achieve the above objectives, the utility model adopts the following technical solution: This utility model provides a cable detection device, including a detection mechanism, a lifting mechanism, a speed sensor, and a light source compensator. The detection mechanism includes a C-shaped structure and a camera. Multiple grooves are evenly arranged on the inner wall of the C-shaped structure, and a camera and a light source compensator are installed in each groove. The camera is used to photograph the cable. The space formed by the inner wall of the C-shaped structure can accommodate the cable entering and exiting. The notch in the C-shaped structure is a cable placement port, and the cable to be detected can be placed horizontally into the cable placement port. The detection mechanism is fixed in a mounting box, and the mounting box is fixedly mounted on the lifting mechanism. The mounting box can drive the detection mechanism to move up and down under the action of the lifting mechanism. The base of the lifting mechanism is connected to a translation mechanism, and the translation mechanism is mounted on a fixed platform.

[0005] Furthermore, a speed sensor is installed on the upper part of one side of the C-shaped structure.

[0006] Furthermore, the C-shaped structure has stabilizing devices installed on the lower parts of both sides.

[0007] Furthermore, the stabilizing device includes a housing, a support body, and a fixing component. The housing is fixed on the mounting box, and the fixing component has a Y-shaped structure. The housing is hollow inside and can accommodate the support body, which can move up and down inside the housing. An elongated fixing hole is provided on the side of the housing, through which the fixing component can fix the support body in a set position.

[0008] Furthermore, the fixed table surface is divided into working areas and protective areas, and the working areas and protective areas do not overlap.

[0009] Furthermore, a protective frame is installed on the protected area.

[0010] Furthermore, the protective frame is a rectangular structure with an opening on one side facing the testing agency and the other four sides sealed.

[0011] Furthermore, the light source compensator comes with a built-in light source concentration cover.

[0012] Furthermore, the four corners of the bottom of the fixed platform are equipped with casters with self-locking function.

[0013] Furthermore, the camera is an industrial 3D camera.

[0014] The technical solution of this utility model has the following beneficial effects: 1. Place the cable to be tested horizontally in the C-shaped testing mechanism. When performing defect detection, the cable can be placed into the testing device without cutting it. It can also be used in conjunction with a production line that is currently producing cables, so as to enable continuous production of conductors and achieve seamless connection between cable production and quality inspection.

[0015] 2. Furthermore, a speed sensor is used to detect the cable running speed (i.e. the cable production line speed) to control the camera image capture speed. When the running speed of the cable under test is lower than the preset value, the camera image capture speed is reduced, and vice versa, the camera image capture speed is increased to ensure that the cable surface data is captured throughout the process.

[0016] 3. Furthermore, the C-shaped structure has cable stabilizing devices installed on the lower part of both sides. The cable stabilizing devices are Y-shaped or similar structures. The cable stabilizing devices on both sides are on the same horizontal line to support and fix the cable, so that the cable under test is suspended in the middle of the space formed by the inner wall of the C-shaped structure, ensuring that the camera can capture the cable from all 360° angles and conduct a comprehensive analysis of the cable surface defects.

[0017] 4. Furthermore, a protective frame is also installed in the protected area. When there is no testing task, the entire testing unit can be moved from the working area to the protective frame through the translation mechanism to avoid damage to the testing unit when not in operation.

[0018] 5. Furthermore, the four corners of the bottom of the fixed platform are equipped with casters with self-locking function for the overall movement of the testing device, reducing labor intensity.

[0019] 6. Furthermore, the camera uses a 3D industrial camera, which can detect the degree of depression and the height of protrusion of defects on the cable surface, effectively eliminating false alarms caused by non-quality issues such as water stains and dirt.

[0031] Example 1 This embodiment provides a cable testing device, such as... Figure 1 As shown, it includes a detection mechanism 3, a lifting mechanism 4, a speed sensor 12, and a light source compensator 14. Figure 2 As shown, the detection mechanism 3 includes a C-shaped structure and a camera 15. Multiple grooves are evenly distributed on the inner wall of the C-shaped structure, and each groove houses a camera 15 and a light source compensator 14. The camera 15 is used to capture images of the cable. The space formed by the inner wall of the C-shaped structure can accommodate the cable's entry and exit. A speed sensor 12 is installed on the upper part of one side of the C-shaped structure. The speed sensor 12 detects the cable's running speed (i.e., the cable production line's production speed) to control the image capture speed of the camera 15. When the running speed of the cable 13 under test is lower than a preset value, the image capture speed of the camera 15 is reduced; conversely, the image capture speed of the camera 15 is increased, ensuring that data on the cable surface is captured throughout the process. The detection mechanism 3 is fixed in a mounting box 9, which is fixedly mounted on a lifting mechanism 4. The mounting box 9 can move the detection mechanism 3 up and down under the action of the lifting mechanism 4.

[0032] In a specific implementation, the C-shaped structure of the inspection mechanism 3 includes openings on both sides and a notch. The openings on both sides of the C-shaped structure are an inlet 16 and an outlet 17, respectively. The cable to be inspected enters through the inlet 16, passes through the space formed by the inner wall of the C-shaped structure, and then exits through the outlet 17. The notch in the C-shaped structure is a cable placement port 18. The cable to be inspected can be placed laterally into the notch end of the C-shaped structure of the inspection mechanism 3, and cable defects are detected by the camera 15. Placing the cable through the notch in the C-shaped structure allows for 3D imaging and analysis of the newly produced cable using a cable surface defect detection device without affecting cable production, and without interrupting cable production.

[0033] In a specific implementation, the camera 15 is used to capture images of the cable. In this embodiment, four cameras 15 are evenly arranged in corresponding grooves on the inner wall of the C-shaped structure, capturing images of the cable from four different angles to comprehensively detect surface defects. Each camera 15 is accompanied by a light source compensator 14, which provides purple laser illumination. The camera 15 is an industrial high-speed 3D camera. The light source compensator 14 has a built-in light source concentrator to prevent light diffusion and focus the light source, making the cable images captured by the camera 15 clearer and improving image quality.

[0034] In a specific implementation, a speed sensor 12 is installed to detect the speed of the cable production line in order to control the image capture speed of the camera 15 and ensure that the data on the cable surface is captured throughout the process.

[0035] In a specific implementation, the camera 15 transmits the acquired image information to the controller, where a preset algorithm performs image analysis to identify cable surface defects. When a defect is detected on the cable surface, the controller transmits a control signal to the alarm device to trigger an alarm, and marks the defect with a red circle on the display unit 2. Simultaneously, red text information, including the defect's location, size, unevenness, and surface area, appears in the upper left corner of the detection screen, reminding personnel to inspect and address the issue. The image information is also saved in real-time in three separate formats: images, documents, and tables, in corresponding directories on the computer for traceability. The image analysis and recognition algorithm in this embodiment is existing technology and has not been improved.

[0036] In a specific implementation, the C-shaped structure has a line-stabilizing device 5 installed on the lower part of both sides. For example... Figure 3 As shown, the cable stabilization device 5 includes a housing 51, a support body 52, and a fixing member 53. The housing 51 is fixed to the mounting box 9. The fixing member 53 has a Y-shaped structure or a similar Y-shaped structure. The housing 51 is hollow inside and can accommodate the support body 52, which can move up and down within the housing 51. A long fixing hole is provided on the side of the housing 51, through which the fixing member 53 can fix the support body 52 in a set position. The vertical position of the support body 52 can be adaptively adjusted according to the size of the cable 13 under test. The cable stabilization devices 5 on both sides are on the same horizontal line, used to support and fix the cable, allowing the cable 13 under test to be suspended in the middle of the space formed by the inner wall of the C-shaped structure, ensuring that the camera 15 can capture a 360° view of the cable for comprehensive analysis of surface defects.

[0037] In a specific embodiment, the base of the lifting mechanism 4 is connected to the translation mechanism 8, so that when the translation mechanism 8 performs translational movement, it can drive the lifting mechanism 4 and the detection mechanism 3 to move in the same direction. The translation mechanism 8 is mounted on the fixed platform 10 and can perform translational movement on the fixed platform 10.

[0038] In a specific implementation, the platform 10 is divided into a working area and a protective area, which do not overlap. The inspection mechanism 3 is fixed in the working area when performing cable defect inspection. A protective frame 1 is also installed in the protective area. The protective frame 1 can be a rectangular structure with an opening on one side facing the inspection mechanism 3 and the other four sides sealed. When there is no inspection task, the inspection mechanism 3 can be moved from the working area into the protective frame 1 via the translation mechanism 8 to prevent damage to the inspection mechanism 3 when not in operation. When there is an inspection task, the inspection mechanism 3 can be moved from the protective frame 1 into the working area via the translation mechanism 8.

[0039] In a specific implementation, the four corners of the bottom of the fixed platform 10 are provided with casters 7 with self-locking function for the overall movement of the detection device.

[0040] In a specific implementation, an electrical control cabinet 6 is also installed under the platform of the fixed platform 10. The electrical control cabinet 6 includes an industrial computer, a PLC (model SMART200), and low-voltage electrical components. The industrial computer is equipped with operating software, which has the function of analyzing and calculating the surface data detected by the 3D camera 15. The PLC is used to collect the speed signal of the speed sensor 12 and send it to the industrial computer, as well as control the movement of various moving parts.

[0041] Working principle of this utility model: The entire testing device is moved to the output end of the production line where the cable 13 to be tested needs to be fixed. The cable 13 to be tested is placed horizontally into the cable placement port 18 and placed on the stabilizing devices 5 on both sides of the C-shaped structure. The testing mechanism 3 is activated to take a full-angle image of the cable 13 to be tested. The light source compensator 14 provides supplementary lighting to ensure image quality. The speed sensor 12 detects the cable running speed (i.e., the cable production line speed) to control the image capture speed of the camera 15. Without affecting the production of cables, the cable surface defect detection device performs 3D image capture and analysis on the newly produced cables. When a defect appears on the cable surface, the system will automatically alarm and mark the defect with a red circle. At the same time, a red text message will appear in the upper left corner of the detection screen, including the location, size, unevenness, and surface area of ​​the defect. Simultaneously, the data is saved in real time in three separate formats: images, documents, and tables, in the corresponding directories on the computer for traceability.

[0042] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
