[0002] Cable visual inspection is an automated inspection method based on machine vision technology, mainly used to inspect key indicators such as surface quality and dimensional accuracy of cables. Its working principle involves capturing images of the cable using a high-resolution camera, and then using image processing and analysis techniques to process the images, thereby identifying surface defects, dimensional deviations, and other problems in the cable.
[0003] In current cable visual inspection of surface quality, due to the long length of the cable, a winding mechanism is usually set on both sides of the inspection equipment to enable continuous cable delivery and inspection, allowing the cable to pass through the inspection equipment for image capture. However, due to the characteristics of the cable, the end of the cable will bend when it is initially inserted and will also bend and swing when the tail end passes through, affecting the cable passing efficiency. Utility Model Content

[0009] As a further description of the above technical solution: a ring-shaped longitudinal LED light strip is fixedly connected to the inner side of the detection ring.
[0010] As a further description of the above technical solution: two brackets are fixedly installed on the left side of the detection ring, and guide wheels are installed on the left end of both brackets.
[0011] As a further description of the above technical solution: a guide ring is fixedly installed on the base, the guide ring is located between the unwinding roller and the detection ring, and the inner sides of both ends of the guide ring are provided with inwardly curved guide surfaces.
[0012] Compared with existing technologies, the advantages of this utility model are:
[0013] This solution uses a guide ring in conjunction with guide wheels on the bracket to guide the cable in a straight line.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;
[0021] Please see Figures 1-4 In this utility model, a cable visual inspection device structure includes a base 1, a support block 2 fixedly installed on the top of the base 1, an inspection ring 3 fixedly installed on the support block 2, industrial cameras 4 arranged at equal intervals fixedly installed inside the inspection ring 3, LED light rings 5 fixedly installed on the inner sides of both ports inside the inspection ring 3, positioning frames 6 installed on both sides of the inspection ring 3, a first guide tube 7 fixedly installed on the right positioning frame 6, and an adjustable guide structure 8 installed on the left positioning frame 6, a take-up roller 10 and an unwind roller 11 installed on the base 1, the take-up roller 10 and the unwind roller 11 being located on both sides of the inspection ring 3 respectively.
[0022] In this invention, the base 1 serves as the device support, and the support block 2 fixes the detection ring 3. In use, the cable coil is first installed onto the unwinding roller 11. Then, the end of the cable is led out and passed through the inside of the first guide tube 7 on the right side. The guide tube guides the end of the cable, allowing it to smoothly enter the detection ring 3. Next, the adjustable guide structure 8 is pushed to align with the end of the first guide tube 7, allowing the end of the cable to smoothly enter the adjustable guide structure 8 and pass through the detection ring 3. The cable then exits from the adjustable guide structure 8 and is wound and fixed to the unwinding roller 11. Finally, the unwinding roller 11 and the take-up roller 10 are started to rotate synchronously at a constant speed to achieve the desired effect. The cable is continuously conveyed, and then supplemented with LED light ring 5. The industrial camera 4 (model: MER3-G3-UV) surrounding the cable is used to collect a comprehensive image of the cable's outer surface and identify defects. This enables the device to guide and insert the cable, making it more efficient and convenient to pass through the inspection area, thus improving installation efficiency. It solves the problem in the existing technology that generally has a take-up and take-down mechanism on both sides of the inspection equipment to achieve continuous cable conveying and inspection, allowing the cable to pass through the inspection equipment for image capture. However, due to the characteristics of the cable, the end of the cable will bend when it is initially inserted and will also bend and swing when it passes through, affecting the efficiency of cable passing.
[0023] Please see Figure 2 and Figure 3 The adjustable guide structure 8 includes two guide rods 81, two sliding blocks 82, a spring 83, and a second guide tube 84. One end of each of the two guide rods 81 is fixedly connected to the positioning frame 6. The opposite sides of the two sliding blocks 82 are slidably connected to the two guide rods 81, and the opposite ends of the two sliding blocks 82 are fixedly connected to the second guide tube 84. The spring 83 is sleeved on the outside of the second guide tube 84. One end of the spring 83 is fixedly connected to the two sliding blocks 82, and the other end of the spring 83 is fixedly connected to the positioning frame 6. The right end of the second guide tube 84 passes through and is slidably connected to the right side of the positioning frame 6.
[0024] In this invention, by pushing two sliding blocks 82 to slide between guide rods 81, the second conduit 84 is pushed to slide inside the positioning frame 6 on the left side, thereby compressing the spring 83, so that the end of the second conduit 84 is connected with the first conduit 7, so that the cable can smoothly transition into the interior of the second conduit 84, making cable threading more convenient and efficient.
[0025] Please see Figure 1 and Figure 3 Among them, the second catheter 84 and the first catheter 7 are both provided with an outward flare 9 at their opposite ends.
[0026] In this invention, the two outward flares 9 make it easier to connect the first conduit 7 and the second conduit 84, and make it easier for the cable to pass through the connection area.
[0027] Please see Figure 1 and Figure 4 Among them, the inner side of the detection ring 3 is fixedly connected with a ring-shaped longitudinal LED light strip 31.
[0028] In this invention, the vertical LED light strip 31, in conjunction with the LED light ring 5, provides comprehensive illumination around the cable, creating a shadowless lighting effect and ensuring image acquisition quality.
[0029] Please see Figure 1 Among them, two brackets 32 are fixedly installed on the left side of the detection ring 3, and guide wheels 33 are installed on the left end of both brackets 32.
[0030] In this invention, the guide wheels 33 on the two brackets 32 guide the cable after testing, and the two guide wheels 33 guide the cable to avoid twisting due to torsional stress, thus ensuring greater stability when taking internal images.
[0031] Please see Figure 1 Among them: a guide ring 12 is fixedly installed on the base 1. The guide ring 12 is located between the unwinding roller 11 and the detection ring 3. Both ends of the guide ring 12 are provided with inwardly curved guide surfaces 13.
[0032] In this invention, the cable led out from the unwinding roller 11 is centered and guided by the guide ring 12, so that it enters the detection ring 3 in a straight line. The arc-shaped guide surface 13 makes the contact between the cable and the guide ring 12 smoother and avoids scratches.
[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
