Description

Technical Field

[0001] This invention relates to the field of cables, specifically to an online detection device for cable surface defects. Background Technology

[0002] Cables generally consist of three parts: a conductor, an insulation layer, and a protective layer. There are typically two types: power cables and control cables. Power cables are mainly used for the transmission and distribution of electrical energy; control cables are mainly used for measurement, protection, and control circuits.

[0003] During cable production, the surface of the cable may be damaged by bumps or processing, causing circuit failures or even serious accidents such as leakage and fire. Therefore, it is necessary to inspect the surface of the cable during production. However, existing surface inspection methods are mostly carried out by manual observation because the defect location is not fixed and the cable cannot be turned over at will. To address this, an online cable surface defect detection device was designed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an online detection device for cable surface defects, which solves the problems that raised dots and recessed areas on the cable surface are difficult to detect and cannot be detected, and that the long size of the cable makes it difficult to flip it over during inspection, thus preventing complete detection.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an online cable surface defect detection device, comprising a detection housing, a bracket fixedly connected to the lower end of the outer surface of the detection housing, a support plate fixedly connected to the outer surface of the bracket, a tension motor fixedly connected to the lower end of the support plate, a drive shaft fixedly connected to the output end of the tension motor, a tension drive belt sleeved on the outer surface of the drive shaft, a limit ring fixedly connected to the upper surface of the support plate, a guide shell fixedly connected to the left end of the detection housing, a light-blocking mechanism fixedly connected to the inner side of the guide shell, a supplementary light ring fixedly connected to the inner side of the light-blocking mechanism, a sensing optical disc fixedly connected to the inner side of the detection housing, the sensing optical disc being coaxial with the light-blocking mechanism, and the inner side of the detection housing... A drive motor is fixedly connected to the side, and a drive gear is fixedly connected to the output end of the drive motor. A drive ring meshes with the outer circumference of the drive gear. A light-blocking tube is fixedly connected to the inner side of the drive ring. A positioning ring is rotatably connected to the right end of the inner side of the light-blocking tube. The positioning ring is fixedly connected to the detection housing. A pressing frame is fixedly connected to the inner side of the positioning ring. A pressing motor is fixedly connected to the upper end of the pressing frame. A pressing shaft is fixedly connected to the output end of the pressing motor. The pressing shaft is located inside the pressing frame. A fixing frame is fixedly connected to the inner side of the light-blocking tube. A touch mechanism is fixedly connected to the inner side of the fixing frame. The end of the touch mechanism away from the center of the light-blocking tube passes through the light-blocking tube. A light-emitting plate is hinged to the outer surface of the light-blocking tube. The touch mechanism contacts the light-emitting plate.

[0006] Preferably, the light-blocking mechanism consists of a connecting ring and a bouncing rod. The connecting ring is fixedly connected to the inner side of the guide shell, and a ring array of bouncing rods is fixedly connected to the surface of the connecting ring. One end of the bouncing rod is a long rod and the other end is a sphere, and the spheres of the bouncing rod fit tightly together.

[0007] Preferably, the photosensitive disc is composed of a disc, a first photosensitive component, and a second photosensitive component. The disc is fixedly connected to the inside of the detection housing. The first photosensitive component is fixedly connected to the inner ring of the disc near the light-blocking mechanism, and the second photosensitive component is fixedly connected to the outer ring of the disc near the light-blocking cylinder.

[0008] Preferably, the pressing frame is N-shaped, and a telescopic shaft is fixedly connected to the outer surface of the pressing frame. The end of the telescopic shaft away from the pressing frame is fixedly connected to the fixed frame, and a telescopic spring is sleeved on the outside of the telescopic shaft.

[0009] Preferably, the touch mechanism consists of a hollow cylinder, a touch cone, a extension spring, and a touch rod. One end of the hollow cylinder is fixedly connected to the surface of the fixed frame, and the other end is slidably connected to the touch cone, which is a conical hollow shell with rounded corners. An extension spring is fixedly connected to the inside of the touch cone, and the touch rod is fixedly connected to the inside of the touch cone. The touch rod is slidably connected to the hollow cylinder and passes through the light-blocking cylinder.

[0010] Preferably, the light-emitting plate consists of a rocker plate and a spotlight. When the rocker plate is hinged to the light-blocking cylinder and is not subjected to external force, one end of the rocker plate is supported by the rocker plate spring and tilted up. The tilted end of the rocker plate is fixedly connected to the spotlight.

[0011] Preferably, the two ends of the fixing frame are circular rings, and the two circular rings are fixedly connected by a spiral rod, and the contact mechanism is fixedly connected to the surface of the spiral rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This online cable surface defect detection device, by activating the supplementary light ring, allows the light source to illuminate the outside of the cable. The bouncing rod of the light-blocking mechanism is close to the cable surface. When a protrusion appears on the cable surface, the bouncing rod is deflected and cannot form a closed ring with the surrounding bouncing rods. The light emitted from the supplementary light ring passes through the bouncing rod and illuminates the surface of the first photosensitive component, thus achieving the effect of detecting the protrusion on the cable surface and solving the problem that the protrusions cannot be detected due to the uniform color of the cable surface.

[0014] 2. This online cable surface defect detection device uses a drive motor to rotate a drive ring via a drive toothed column, causing the light-blocking cylinder to rotate. This, in turn, causes the fixed frame to rotate the contact mechanism on the outer surface of the cable, bringing the contact cone into contact with the cable surface. When a depression appears on the cable surface, the extension spring pushes the contact cone, moving the contact rod away from the rocker. The spotlight, influenced by the spring under the rocker, tilts up and illuminates the second photosensitive component, thus achieving the effect of detecting the location of the depression on the cable surface and solving the problem that cable depressions are difficult to detect.

[0015] 3. This online cable surface defect detection device uses a ring composed of a light-blocking mechanism to wrap around the outside of the cable for inspection, eliminating the need to flip the cable during inspection. The contact mechanism rotates on the cable surface for contact, and when the contact cone encounters a depression, it can quickly rise and fall to provide multiple different spotlight warnings, preventing false detections. This achieves the effect of inspection without flipping the cable, solving the problem that cables with long volumes are difficult to flip and cannot be fully inspected during inspection.

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.

[0025] like Figure 1-7 As shown, an online cable surface defect detection device includes a detection housing 1. A bracket 2 is fixedly connected to the lower end of the outer surface of the detection housing 1. A support plate 3 is fixedly connected to the outer surface of the bracket 2. A tension motor 4 is fixedly connected to the lower end of the support plate 3. A transmission shaft 5 is fixedly connected to the output end of the tension motor 4. A tension transmission belt 6 is sleeved on the outer surface of the transmission shaft 5. A limit ring 7 is fixedly connected to the upper surface of the support plate 3. A guide shell 8 is fixedly connected to the left end of the detection housing 1. A light-blocking mechanism 9 is fixedly connected to the inner side of the guide shell 8. A supplementary light ring 10 is fixedly connected to the inner side of the light-blocking mechanism 9. The light-blocking mechanism 9 consists of a connecting ring 901 and a bouncing rod 902. The connecting ring 901 is fixedly connected to the inner side of the guide shell 8. A ring array of bouncing rods 902 is fixedly connected to the surface of the connecting ring 901. One end of the bouncing rod 902 is a long rod and the other end is a sphere. The spheres of the bouncing rods 902 fit tightly together. The light-blocking mechanism 9 can block the light emitted by the supplementary light ring 10 in combination, so that the cable can only be detected when a defect occurs.

[0026] A sensing disc 11 is fixedly connected to the inside of the detection housing 1. The sensing disc 11 is coaxial with the light-blocking mechanism 9. A drive motor 12 is fixedly connected to the inside of the detection housing 1. A drive gear 13 is fixedly connected to the output end of the drive motor 12. A drive ring 14 meshes with the outer circumferential surface of the drive gear 13. A light-blocking tube 15 is fixedly connected to the inside of the drive ring 14. A positioning ring 16 is rotatably connected to the right end of the inner side of the light-blocking tube 15. The positioning ring 16 is fixedly connected to the detection housing 1. The sensing disc 11 consists of a disc 111, a first photosensitive component 112, and a second photosensitive component 113. The disc 111 is fixedly connected to the inside of the detection housing 1. The first photosensitive component 112 is fixedly connected to the inner ring of the disc 111 near the light-blocking mechanism 9. The second photosensitive component 113 is fixedly connected to the outer ring of the disc 111 near the light-blocking tube 15. By installing photosensitive components at different positions on both sides of the sensing disc 11, different feedback effects can be obtained when different defects occur in the cable.

[0027] A pressing frame 17 is fixedly connected to the inner side of the positioning ring 16. A pressing motor 18 is fixedly connected to the upper end of the pressing frame 17. A pressing shaft 19 is fixedly connected to the output end of the pressing motor 18. The pressing shaft 19 is located inside the pressing frame 17. A fixing frame 20 is fixedly connected to the inner side of the light-blocking tube 15. The pressing frame 17 is N-shaped. A telescopic shaft 171 is fixedly connected to the outer surface of the pressing frame 17. The end of the telescopic shaft 171 away from the pressing frame 17 is fixedly connected to the fixing frame 20. A telescopic spring 172 is sleeved on the outer side of the telescopic shaft 171. The pressing frame 17 can clamp and organize the cable to prevent the cable from twisting when the light-blocking tube 15 rotates.

[0028] A touch mechanism 21 is fixedly connected to the inner side of the fixed frame 20. The two ends of the fixed frame 20 are rings, and the two rings are fixedly connected by a spiral rod. The touch mechanism 21 is fixedly connected to the surface of the spiral rod. The fixed frame 20 can support the touch mechanism 21 so that each contact point of the touch mechanism 21 is in the appropriate position.

[0029] The end of the touch mechanism 21 furthest from the center of the light-blocking cylinder 15 passes through the light-blocking cylinder 15. A light-emitting plate 22 is hinged to the outer surface of the light-blocking cylinder 15. The touch mechanism 21 contacts the light-emitting plate 22. The touch mechanism 21 consists of a hollow cylinder 211, a touch cone 212, a extension spring 213, and a touch rod 214. One end of the hollow cylinder 211 is fixedly connected to the surface of the fixing frame 20, and the other end is slidably connected to the touch cone 212. The touch cone 212 is a conical hollow shell with rounded corners. The extension spring 213 is fixedly connected to the inner side of the touch cone 212, and the touch rod 214 is fixedly connected to the inner side of the touch cone 212. The touch rod 214 is slidably connected to the hollow cylinder 211 and passes through the light-blocking cylinder 15. The touch mechanism 21 can use the touch cone 212 to detect the surface depression of the cable and use the touch rod 214 to transmit the feedback.

[0030] The light-emitting plate 22 consists of a rocker plate 221 and a spotlight 222. When the rocker plate 221 is hinged to the light-blocking tube 15 and is not subjected to external force, one end is supported by the rocker plate spring and tilted up. The tilted end of the rocker plate 221 is fixedly connected to the spotlight 222. The rocker plate 221 has a "V" shape and a spring is installed on the lower side. After the light-emitting plate 22 can tilt up, the second photosensitive component 113 will make a feedback through the illumination of the spotlight 222.

[0031] In use, first place the cable into the limiting ring 7, then start the tension motors 4 on both sides to drive the transmission shaft 5 to rotate, causing the tension transmission belt 6 to rotate, straighten, and drag the cable through the inside of the detection housing 1. When the cable enters the inside of the detection housing 1, first activate the supplementary light ring 10 so that the light source can illuminate the outside of the cable. The spring rods 902 of the light blocking mechanism 9 are close to the cable surface. Since each spring rod 902 is independent, when there is a protrusion on the cable surface, the spring rod 902 is pushed up and cannot form a closed ring with the surrounding spring rods 902. The light emitted from the supplementary light ring 10 passes through the spring rods 902. The light shines on the surface of the first photosensitive component 112, thereby detecting the protrusion position on the cable surface. The cable passes through the photosensitive disc 11, and the drive motor 12 is started to drive the drive ring 14 to rotate through the drive gear column 13, causing the light-blocking tube 15 to rotate. As a result, the fixing frame 20 drives the touch mechanism 21 to rotate on the outer surface of the cable, so that the touch cone 212 contacts the cable surface. When the cable surface is concave, the extension spring 213 pushes the touch cone 212, so that the touch rod 214 moves away from the rocker plate 221. The spotlight 222 is tilted up by the spring under the rocker plate 221 to shine on the second photosensitive component 113, thereby detecting the concave position on the cable surface.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
