Description

Technical Field

[0001] The present invention relates to the technical field of cable detection, in particular to an AI detector for cable surface defects. Background Art

[0002] Cable surface defect detection technology has evolved from manual visual inspection to automated optical inspection. Traditional cable surface defect detection mainly relies on manual visual and tactile inspection, which has inherent defects such as low detection efficiency, unstable quality, and susceptibility to subjective factors. With the development of machine vision and artificial intelligence technologies, automated optical inspection systems based on image processing have gradually become a key technology for surface quality control in the cable manufacturing process. At present, multi-camera array inspection systems are widely used in industrial sites. Through the coordinated cooperation of multiple industrial cameras and light sources, all-round imaging of the cable surface is achieved. However, in actual applications, existing array inspection systems still have technical bottlenecks such as detection blind spots, poor adaptability, and insufficient stability.

[0003] Existing detection equipment generally adopts a fixed camera layout scheme. This static layout makes it difficult to completely eliminate detection blind spots during continuous transportation, and the detection accuracy is easily affected by cable shaking and eccentricity. At the same time, because the guide and tensioning devices on both sides of the detector make the cable suspended in the detection area, or when the detector detects cables of different specifications, the adaptability and fit of the guide and tensioning devices will vary to varying degrees, so radial shaking and eccentricity are likely to occur during continuous transportation, affecting the accuracy and reliability of the detection. Based on the above problems, there is an urgent need for an AI detector for cable surface defects to solve key technical problems such as detection blind spots, specification adaptability and operational stability under continuous transportation conditions.

Example 1

[0034] Reference Figures 1 to 9 , which is the first embodiment of the present invention, provides a cable surface defect AI detector, which includes a guide unit 1, including a box 11, and a pair of guide components 12 arranged on both sides of the box 11;

[0035] The dynamic data collection unit 2 includes a pair of support plates 21 fixed to the interior of the housing 11, a gear ring 22 provided on the surface of each support plate 21, a pair of synchronous gears 23 meshing with the side walls of the gear rings 22, a pair of motors 24 fixed to the surface of the support plates 21, a number of data collection components 25 fixed between the two gear rings 22, and a number of staggered light sources 26 fixed to the inner ring of each gear ring 22;

[0036] The positioning unit 3 includes a ratchet ring 31 disposed on the inner ring of the gear ring 22 and a plurality of positioning components 32 fixed on the inner ring of the ratchet ring 31 .

[0037] Furthermore, the box body 11 includes a first access opening 111 passing through one side thereof;

[0038] The guide assembly 12 includes a fixed frame 121 , a plurality of pulleys 122 and a tensioning arm 123 fixed to a surface of the fixed frame 121 , and a tensioning wheel 124 fixed to a surface of the tensioning arm 123 .

[0039] Furthermore, the support plate 21 includes a second loading and unloading port 211 formed on its surface, two concentric dovetail bars 212 fixed to the surface of the support plate 21 , and a plurality of blocking rods 213 fixed to the hollow areas of the dovetail bars 212 .

[0040] Furthermore, the gear ring 22 includes a plurality of spherical nozzles 221 fixed to the inner wall of the gear ring 22, a spring cavity 222 opened at the center of the spherical nozzle 221, a first ball 223 arranged inside the spherical nozzle 221, a first spring 224 arranged inside the spring cavity 222, and a third access port 225 opened on one side of the gear ring 22.

[0041] Furthermore, the acquisition component 25 includes a pair of guide rails 251 , a sliding seat 252 sleeved on the outer wall of the guide rails 251 , and an industrial camera 253 fixed on the surface of the sliding seat 252 .

[0042] Furthermore, the ratchet ring 31 includes a plurality of traction posts 311 fixed on its surface, and a fourth access opening 312 opened on one side of the ratchet ring 31 .

[0043] Furthermore, the positioning assembly 32 includes a sleeve 321 , a positioning rod 322 sleeved inside the sleeve 321 , a second spring 323 sleeved on the shaft of the positioning rod 322 , and a limiting rod 324 hinged inside the side wall of the sleeve 321 .

[0044] Furthermore, the sleeve 321 includes an opening 3211 formed on a side thereof and a hinge post 3212 fixed to an inner wall of the opening.

[0045] Furthermore, the positioning rod 322 includes a ratchet bar 3221 , a guide rod 3222 fixed to one end of the ratchet bar 3221 , a ball sleeve 3223 fixed to the other end of the ratchet bar 3221 , and a second ball 3224 engaged in the ball sleeve 3223 .

[0046] Furthermore, the limiting rod 324 includes a beak block 3241 and a spring piece 3242 fixed to one side thereof, and an extension rod 3243 fixed to the end of the limiting rod 324 .

[0047] It should be noted that the dynamic acquisition unit 2 and positioning unit 3 are fixed in the center of the detector's housing 11 using various brackets. A first access opening 111 for accessing and placing cables is located on one side of the housing 11. This opening 111 runs through one side of the housing 11 and is located in the center of the housing 11. A pair of guide assemblies 12 are fixed to the center of each side of the housing 11, where the first access opening 111 terminates.

[0048] Specifically, the fixing brackets 121 are fixed to positions adjacent to the center of both sides of the box body 11. A pair of pulleys 122 staggered up and down are fixed to the surface of a single fixing bracket 121. The center of the pulley 122 is used to pass the continuously input or output cable, and the two adjacent pulleys can adjust the spacing of the passing cables. In order to ensure a certain tension in the cable, and the gap points to the center position of the end of the first access port 111, a tensioning arm 123 is hinged on the surface of one or both sides of the fixing bracket 121. The tensioning arm 123 is adjacent to the pulley 122, and a tensioning wheel 124 is fixed to the surface of the tensioning arm 123. The tensioning arm 123 itself has a certain downward pressure, which is used to apply pressure to the passing cable, thereby ensuring the tension during the cable transportation process. In the prior art, a similar method is also commonly used for guiding the input and output of cables, which will not be elaborated here.

[0049] Preferably, there are two support plates 21, fixed to the inner wall or bottom of the box body 11 via brackets or direct connection, symmetrically arranged with space between them. A second access opening 211 similar in shape to the first access opening 111 is provided on one side of the support plate 21. The second access opening 211 is aligned with the first access opening 111, and the end is also located at the center of the support plate 21, ensuring that the cable can be easily accessed. In addition, two concentric dovetail strips 212 of different sizes are fixed on the surface of the support plate 21. The dovetail strip 212 is annular and takes the center position of the end of the second loading and unloading port 211 as the center of the circle, and dovetail grooves that can cooperate with the dovetail strip 212 are also provided on the surfaces of the gear ring 22 and the ratchet ring 31. Specifically, the gear ring 22 is installed on the dovetail strip 212 of the outermost circle, and the gear ring 22 can rotate circumferentially on it. Similarly, the ratchet ring 31 is installed on the dovetail strip 212 of the innermost circle, and can also rotate circumferentially.

[0050] Preferably, a plurality of spherical nozzles 221 are fixed to the inner wall of the gear ring 22. In this embodiment, there are six evenly distributed spherical nozzles 221. In practice, there are at least two spherical nozzles 221 arranged at a certain angle. A spring cavity 222 is defined along the axis of the spherical nozzle 221. The spring cavity 222 extends through one side of the spherical nozzle 221. A first ball 223 is positioned within the spring cavity 222, near the spherical nozzle 221. It is important to note that the maximum cross-sectional area of the first ball 223 is smaller than the opening area of the spherical nozzle 221, that is, the cross-section of the spring cavity 222 is larger than the opening area of the spherical nozzle 221, and the transition between the two is continuous, preventing the first ball 223 from escaping the spherical nozzle 221. A first spring 224 is also provided between the bottom of the spring cavity 222 and the first ball 223. Under normal conditions, the first ball 223 is pushed toward the spherical nozzle 221, leaving a portion of the first ball 223 exposed.

[0051] The third access opening 225 is opened on one side of the surface of the gear ring 22, making the gear ring 22 C-shaped, and its function is the same as the first access opening 111 and the second access opening 211. Similarly, the ratchet ring 31 is also provided with a fourth access opening 312, which has the same function as above.

[0052] In addition, two motors 24 are fixed to the surface of one of the support plates 21, symmetrically distributed and adjacent to the gear ring 22. The shaft ends of the motors 24 pass through the support plate 21 and extend to the gear ring 22. A synchronous gear 23 is fixed to the shaft end of each motor 24. The two synchronous gears 23 are respectively engaged with the outer ring of the gear ring 22. When the two motors 24 rotate in the same direction, they can drive the gear ring 22 to rotate. It should be noted that due to the presence of the third access port 225 of the gear ring 22, the teeth of the gear ring 22 are discontinuous. When there is only one motor 24, it will disengage when encountering the third access port 225, causing the gear ring 22 to lose transmission. Therefore, a second motor 24 is required to connect.

[0053] Preferably, when one motor 24 is used, power transmission between the two synchronous gears 23 can be established through belt transmission, thereby ensuring that a power transmission chain always exists in the gear ring 22.

[0054] Preferably, two guide rails 251, totaling three in total, are fixed between the two gear rings 22. Each set of guide rails 251 is fitted with a sliding seat 252, allowing the sliding seat 252 to move axially along the guide rails 251. Furthermore, fastening bolts are provided on the sides of the sliding seat 252 adjacent to the guide rails 251. To lock the sliding seat 252 in place on the guide rails 251, the fastening bolts are tightened until they press against the guide rails 251, securing the sliding seat 252 in place. Industrial cameras 253 are also fixed to the surface of the sliding seat 252, with the three industrial cameras 253 forming a 120° angle with each other. Another common array arrangement in the prior art is an array of four industrial cameras 253. Therefore, when the gear ring 22 rotates, it can drive each industrial camera 253 to perform rotational scanning and collect data. When the cable is transported, the scanning is spiral. Compared with the traditional static detection mode, the spiral scanning can avoid detection blind spots. Since the camera can only collect the surface area it is facing, defects such as depressions and protrusions on the cable surface may be blocked at an oblique angle, leaving suspicious areas. Especially when the defect is located in the boundary area of adjacent cameras, the detection effect is poor, such as the transition area between adjacent cameras, the shadow area on the cable surface, the side wall of the deep defect, etc.

[0055] Preferably, the rotation speed of the gear ring 22 needs to be coordinated with the cable conveying speed to ensure that the cable surface is completely scanned without blind spots. Specifically, assume that the cable conveying speed is Vm / min; the outer ring rotation angular velocity is ωrad / s; the cable outer diameter is Dmm; the camera field of view width is Wmm; and the outer ring radius is Rmm.

[0056] The speed coordination relationship is derived as follows: the cable's surface circumference is πD, and the time it takes to complete one rotation is T = 2π / ω. The cable's travel distance is then L = V × T. To ensure seamless coverage, L ≤ W must be satisfied. Therefore, V × 2π / ω ≤ W, or ω ≥ 2πV / W. This ensures seamless coverage along the spiral trajectory.

[0057] Preferably, the ratchet ring 31 is also C-shaped, with several traction posts 311 fixed to its surface. In this embodiment, five are evenly distributed. Each first ball bearing 223 engages the gaps between the ratchet teeth. When the gear ring 22 rotates, the first ball bearings 223 contact the ratchet tooth walls, driving the ratchet ring 31 to rotate. If the ratchet ring 31 is blocked and unable to rotate, the first ball bearings 223 are forced back into the spherical mouth 221 due to further rotation of the gear ring 22, thereby passing the highest point of the ratchet teeth. Therefore, the maximum torque transmitted from the gear ring 22 to the ratchet ring 31 depends on the elasticity of the first spring 224 and the number of first ball bearings 223.

[0058] Preferably, a number of staggered light sources 26 are evenly fixed in the inner area of the ratchet ring 31 around the center of the end of the second loading and unloading port 211. In this embodiment, two groups of six staggered light sources 26 are used to illuminate the cable image acquisition area from different angles. Each staggered light source 26 is composed of two lamps with extremely strong light directionality, and there is an angle between the pointing angles of the two light sources, which further prevents the presence of shadows or suspicious areas in the acquisition area, resulting in reduced acquisition accuracy.

[0059] Preferably, sleeves 321 are fixed between each staggered light source 26. Five sleeves 321 are provided, excluding the second access opening 211, which cannot be installed. This number matches the number of pull posts 311 and the number of blocking rods 213 fixed to the surface of the support plate 21. Each sleeve 321 is a one-way opening, pointing toward the center of the ratchet ring 31. A strip-shaped opening 3211 is also defined on the sidewall of the sleeve 321. A hinge post 3212 is fixed within the opening 3211, adjacent to the center of the ratchet ring 31. This hinge post 3212 is used to mount a limit rod 324.

[0060] A positioning rod 322 is also mounted within the sleeve 321, allowing for axial movement. The main body of the positioning rod 322 is composed of a guide rod 3222, a ratchet bar 3221, and a ball sleeve 3223, which are fixed in sequence. The guide rod 3222 extends through the closed end of the sleeve 321, and a stopper is fixed at the end of the guide rod 3222 to prevent the positioning rod 322 from separating from the sleeve 321. A second ball 3224 is engaged within the ball sleeve 3223. Similar to the first ball 223, the second ball 3224 can move within the ball sleeve 3223 without disengaging, thereby reducing wear on the cable surface. A second spring 323 is also mounted on the guide rod 3222. Its two ends contact the bottom of the sleeve 321 and the end of the ratchet bar 3221, respectively, to push the positioning rod 322 out of the sleeve 321 under normal conditions.

[0061] Since each positioning rod 322 points to the center of the ratchet ring 31 and is located on both sides of the detection area, when the cable is placed therein, both ends of the cable's detection area will be supported by each second ball 3224. At this time, the positioning rod 322 will retreat a corresponding distance due to the different cable diameters. When the cable is transported, the second ball 3224 can both support and position the cable, reduce the distance the cable is suspended, and further reduce the shaking of the cable during transportation, ensuring that the cable is always in the ideal detection position. It can also adapt to the detection of cables of different sizes to achieve the same detection accuracy and reduce the friction of cable transportation.

[0062] Preferably, a spring clip 3242 is fixed to the sidewall where the limiting rod 324 connects to the hinge post 3212. Normally, the spring clip 3242 maintains a certain angle with the limiting rod 324 and contacts one side of the teeth of the ratchet bar 3221, pushing the limiting rod 324 toward the nearest blocking rod 213. A beak block 3241 is also fixed to the middle of the limiting rod 324, adjacent to the ratchet bar 3221, to form a limiting relationship between the two. An extension rod 3243 is also fixed to the end of the limiting rod 324 facing away from the center of the ratchet ring 31. The extension rod 3243 is adjacent to the traction post 311 and extends beyond the traction post 311.

[0063] During use, the third access port 225 and the fourth access port 312 are aligned with the first access port 111 and the second access port 211. The cable to be tested needs to be placed inside the access port, and then the cables are placed in the two sets of guide components 12 respectively and then tensioned. At this time, the cable is pressed between the positioning components 32 on both sides of the detection area, that is, the surface of the cable squeezes the second balls 3224, causing the positioning rods 322 to squeeze the second springs 323 and retreat. At this time, the positioning rods 322 are not limited.

[0064] When using dynamic compensation mode, the two motors 24 rotate in tandem, driving the corresponding synchronous gears 23 to rotate the gear ring 22. The gear ring 22 then rotates the ratchet ring 31 through the contact between the first balls 223 and the ratchet teeth on the outer wall of the ratchet ring 31. The pull posts 311 on the surface of the ratchet ring 31 push the limit rod 324, causing it to deflect. At this point, the springs 3242 deform and press against the limit rod 324 until the beak 3241 engages the ratchet teeth on the nearest ratchet bar 3221. At this point, each positioning rod 322 is restrained, effectively preventing radial sway caused by the cable hanging in the air, ensuring the cable remains in the ideal detection position and improving image acquisition quality. The gear ring 22 then rotates further, while the ratchet ring 31 is restrained by the sleeve 321 and cannot rotate further. At this point, the first balls 223 are squeezed back into the spherical beak 221, passing over the ratchet teeth on the outer wall of the ratchet ring 31. As the gear ring 22 rotates continuously, it consistently applies a range of force to the limit rod 324 against the ratchet bar 3221 without causing motion interference. This means that when the gear ring 22 rotates, each positioning assembly 32 maintains its positional limit on the cable. When the gear ring 22 is stationary, cables of varying diameters can be placed and retrieved, achieving adaptive dimensional control. After adaptive adjustment, the current positional limit can be maintained even after the gear ring 22 rotates. As the cable is continuously conveyed and the industrial camera 253 rotates, spiral scanning ensures that the cable surface is completely scanned, eliminating blind spots.

[0065] When using the traditional static detection mode, only the transmission cable is required, and each industrial camera 253 performs corresponding image acquisition, and then uses AI to detect and analyze surface defects.

[0066] When the cable needs to be removed from or reinserted into the access port, the gear ring 22 first stops rotating, which in turn interrupts the power to the ratchet ring 31. The limiting rod 324 is no longer subjected to the continuous pressure from the ratchet ring 31, and the spring 3242 then returns to its original position, forcing the limiting rod 324 away from the ratchet bar 3221. At this point, the positioning assemblies 32 are no longer restricted, and driven by the limiting rods 324, they push the ratchet ring 31 and gear ring 22 in opposite directions, allowing the cable to be easily removed or reinserted. It should be noted that the ratchet ring 31 and gear ring 22 can rotate in opposite directions to ensure that the access ports are aligned.

[0067] In summary, the present invention achieves zero-dead-angle detection through a rotary detection method and employs adaptive positioning to ensure stable transport and positioning accuracy for cables of varying specifications. This invention boasts high detection coverage, strong adaptability, and stable and reliable operation. Compared to existing technologies, it can achieve comprehensive detection of surface defects during continuous cable transport, while simultaneously addressing the issue of radial cable sway during inspection, improving detection accuracy and production efficiency. It also accommodates both dynamic and static scanning acquisition methods, resulting in increased detection flexibility.
