Description

Technical Field

[0001] The 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 undergone a technological evolution from manual visual inspection to automated optical inspection. Traditional cable surface defect detection mainly relies on manual visual and tactile inspection. This method has inherent defects such as low detection efficiency, unstable quality, and susceptibility to subjective factors. With the development of machine vision and artificial intelligence technology, 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, the existing array inspection systems still have technical bottlenecks such as detection blind spots, poor adaptability, and insufficient stability in practical applications.

[0003] Existing detection equipment generally adopts a fixed camera layout solution. This static layout is 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 change 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 cable surface defect detector to solve key technical problems such as detection blind spots, specification adaptability and operation stability under continuous transportation conditions.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention.

Example 1

[0031] Reference Figure 1 to Figure 9 , which is the first embodiment of the present invention, and 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; The dynamic collection unit 2 includes a pair of support plates 21 fixed inside the box 11, a gear ring 22 arranged on the surface of each support plate 21, a pair of synchronous gears 23 meshed with the side walls of the gear ring 22, a pair of motors 24 fixed on the surface of the support plate 21, a plurality of collection components 25 fixed between the two gear rings 22, and a plurality of staggered light sources 26 fixed at the inner circle of each gear ring 22; The positioning unit 3 includes a ratchet ring 31 disposed on the inner circle of the gear ring 22 , and a plurality of positioning components 32 fixed on the inner circle of the ratchet ring 31 .

[0032] Furthermore, the box body 11 includes a first access opening 111 penetrating through one side thereof; The guide assembly 12 includes a fixed frame 121 , a plurality of pulleys 122 and a tensioning arm 123 fixed to the surface of the fixed frame 121 , and a tensioning wheel 124 fixed to the surface of the tensioning arm 123 .

[0033] Furthermore, the support plate 21 includes a second loading and unloading opening 211 opened on the surface thereof, 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 .

[0034] 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 .

[0035] 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 .

[0036] Furthermore, the ratchet ring 31 includes a plurality of traction posts 311 fixed on the surface thereof, and a fourth access opening 312 opened on one side of the ratchet ring 31 .

[0037] 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 rod body of the positioning rod 322 , and a limiting rod 324 hinged inside the side wall of the sleeve 321 .

[0038] Furthermore, the sleeve 321 includes an opening 3211 opened on the side thereof, and a hinge column 3212 fixed to the inner wall of the opening.

[0039] 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 .

[0040] 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 .

[0041] It should be noted that the dynamic acquisition unit 2 and the positioning unit 3 are fixed in the middle position inside the box 11 of the detector by various brackets. A first access opening 111 for taking in and putting in the cable is opened on one side of the box 11. The first access opening 111 runs through one side of the box 11 and is placed in the center of the box 11. A pair of guide components 12 are fixed at the center position of both sides of the box 11, that is, where the first access opening 111 ends. Specifically, the fixing frame 121 is fixed at the positions adjacent to the center of both sides of the box body 11, and a pair of pulleys 122 staggered up and down are fixed on the surface of a single fixing frame 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 of the cable, and the gap points to the center position of the end of the first access port 111, a tensioning arm 123 is also hinged on the surface of the fixing frame 121 on one or both sides. The tensioning arm 123 is adjacent to the pulley 122, and a tensioning wheel 124 is also fixed on 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, so as to ensure the tension during the cable transportation process. In the prior art, a similar method is also usually used for guiding the input and output of cables, which will not be elaborated here.

[0042] Preferably, there are two support plates 21, which are fixed to the inner wall or bottom of the box body 11 by means of brackets or direct connection, and are symmetrically distributed with a space between them. A second access opening 211 having a shape similar to the first access opening 111 is provided on one side of the surface of the support plate 21, and the second access opening 211 is aligned with the first access opening 111, and the cut-off end is also at the center of the support plate 21, so as to ensure that the cable can be taken and placed therefrom. 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 opened 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 thereon. Similarly, the ratchet ring 31 is installed on the dovetail strip 212 of the innermost circle, and can also rotate circumferentially.

[0043] Preferably, a plurality of spherical nozzles 221 are fixed on the inner wall of the gear ring 22. In this embodiment, the number is six and they are evenly distributed. In actual selection, there are at least two and there is a certain angle. A spring cavity 222 is opened in the axial direction of the spherical nozzle 221. The spring cavity 222 is unilaterally penetrated. A first ball 223 is built in the spring cavity 222 and near the spherical nozzle 221. It should be noted 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-sectional area of ​​the spring cavity 222 is larger than the opening area of ​​the spherical nozzle 221. The transition between the two is continuous, which can prevent the first ball 223 from detaching from the spherical nozzle 221. A first spring 224 is also provided between the bottom of the spring cavity 222 and the first ball 223, which can push the first ball 223 toward the spherical nozzle 221 under normal conditions, so that the first ball 223 is partially exposed.

[0044] The third access opening 225 is provided on one side of the surface of the gear ring 22, so that the gear ring 22 is in the shape of a C, and its function is the same as that of the first access opening 111 and the second access opening 211. Similarly, a fourth access opening 312 is also provided on the ratchet ring 31, and its function is the same as that of the first access opening 111 and the second access opening 211.

[0045] In addition, two motors 24 are fixed on the surface of one of the support plates 21, which are 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, and the shaft ends of each motor 24 are fixed with synchronous gears 23. The two synchronous gears 23 are respectively meshed 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 be disengaged when encountering the third access port 225, causing the gear ring 22 to lose transmission, so a second motor 24 is required for connection.

[0046] Preferably, when one motor 24 is used, power transmission between the two synchronous gears 23 can be established through belt transmission, thereby ensuring that the gear ring 22 always has a power transmission chain.

[0047] Preferably, two guide rails 251 are fixed between the two gear rings 22, and a sliding seat 252 is sleeved on each guide rail 251, so that the sliding seat 252 can move axially along the guide rail 251. In addition, a fastening bolt is provided on the side of the sliding seat 252 adjacent to the guide rail 251. When it is necessary to lock the position of the sliding seat 252 on the guide rail 251, the fastening bolt is tightened and pressed against the guide rail 251, and the sliding seat 252 is limited at this time. An industrial camera 253 is also fixed on the surface of the sliding seat 252, and the angle between the three industrial cameras 253 is 120°. Another commonly used array method in the prior art is the 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 data on the surface area directly facing it, 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 a deep defect, etc.

[0048] 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, 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.

[0049] The speed coordination relationship is derived as follows: the circumference of the cable surface is πD, and the time for one rotation is T=2π / ω. At this time, the cable advance distance is L=V×T. To ensure no-dead-angle coverage, L≤W must be satisfied, so V×2π / ω≤W is obtained, that is, ω≥2πV / W. Therefore, it can ensure no-gap coverage of the spiral track.

[0050] Preferably, the ratchet ring 31 is also in the shape of a C, and a plurality of traction columns 311 are fixed on its surface. In this embodiment, five traction columns 311 are selected and evenly distributed. Each first ball 223 is engaged in the gap between the ratchet teeth. When the gear ring 22 rotates, the first ball 223 can drive the ratchet ring 31 to rotate through the contact between the first ball 223 and the ratchet wall. When the ratchet ring 31 is blocked and cannot rotate, the first ball 223 will be forced to press back to the spherical mouth 221 due to the further rotation of the gear ring 22, thereby passing the highest point of the ratchet teeth. Therefore, the maximum torque transmitted by the gear ring 22 to the ratchet ring 31 depends on the elasticity of the first spring 224 and the number of the first ball 223.

[0051] 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 cutoff point of the second loading and unloading port 211. In the present 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 source 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.

[0052] Preferably, sleeves 321 are fixed between each staggered light source 26, and there are five sleeves in total, except for the second access opening 211, which cannot be installed, which is consistent with the number of traction posts 311 and the number of blocking rods 213 fixed on the surface of the support plate 21. Each sleeve 321 is a one-way opening, and the openings all point to the center of the ratchet ring 31, and a strip-shaped opening 3211 is opened on the side wall of the sleeve 321, and a hinge column 3212 is fixed inside the opening 3211 adjacent to the center of the ratchet ring 31, and the hinge column 3212 is used to install the limit rod 324.

[0053] A positioning rod 322 is also sleeved inside the sleeve 321, and the positioning rod 322 can move axially therein. The main body of the positioning rod 322 is composed of three parts, a guide rod 3222, a ratchet bar 3221 and a ball sleeve 3223, which are fixed in sequence. The guide rod 3222 passes through the closed end of the sleeve 321, and a limit block is fixed at the end of the guide rod 3222 to prevent the positioning rod 322 from detaching from the sleeve 321. A second ball 3224 is engaged inside the ball sleeve 3223. The second ball 3224 is similar to the first ball 223 and can move in the ball sleeve 3223 without detaching. The second ball 3224 can reduce the wear on the cable surface. A second spring 323 is also sleeved on the guide rod 3222. The two ends of the second spring 323 are respectively in contact with the bottom of the sleeve 321 and the end of the ratchet bar 3221, and can push the positioning rod 322 out of the sleeve 321 under normal conditions.

[0054] 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 that the cable is suspended in the air, and further reduce the shaking of the cable during transportation, ensuring that the cable is always in an 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.

[0055] Preferably, a spring sheet 3242 is fixed to the side wall where the limit rod 324 is connected to the hinge column 3212. The spring sheet 3242 maintains a certain angle with the limit rod 324 under normal conditions, and contacts one side of the teeth of the ratchet bar 3221, and pushes the limit rod 324 to the nearest blocking rod 213. In the middle position of the limit rod 324, a beak block 3241 is fixed to one side adjacent to the ratchet bar 3221, and a limit relationship can be formed between the two. An extension rod 3243 is also fixed to the end of the limit rod 324 facing away from the center of the ratchet ring 31, and the extension rod 3243 is adjacent to the traction column 311 and exceeds the traction column 311 in length.

[0056] When in 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 into 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.

[0057] When the dynamic compensation mode is adopted, the two motors 24 rotate in coordination, and the corresponding synchronous gears 23 drive the gear ring 22 to rotate. The gear ring 22 then drives the ratchet ring 31 to rotate through the contact between the first balls 223 and the ratchet teeth on the outer wall of the ratchet ring 31. The traction columns 311 on the surface of the ratchet ring 31 will push the limit rod 324 to deflect, and the spring piece 3242 will deform and then stick to the limit rod 324 until the eagle beak block 3241 is buckled into the ratchet teeth on the nearest ratchet bar 3221. At this time, all the positioning rods 322 are limited, which can effectively prevent the radial shaking of the cable due to suspension, ensure that the cable is always in the ideal detection position, and improve the image acquisition quality. Then the gear ring 22 rotates further, and the ratchet ring 31 is restricted by the sleeve 321 and cannot rotate further. At this time, the first balls 223 will be squeezed back into the spherical mouth 221, so as to pass over the ratchet teeth on the outer wall of the ratchet ring 31. With the continuous rotation of the gear ring 22, the limiting rod 324 can always provide a certain range of continuous force against the ratchet bar 3221, and no motion interference will occur, that is, when the gear ring 22 rotates, each positioning component 32 can maintain the limiting effect on the cable, and when the gear ring 22 does not rotate, cables of different diameters can be taken and placed therein to achieve size adaptation, and after adaptation, the current limiting position can be maintained after the gear ring 22 rotates. With the continuous transmission of the cable and the rotation of the industrial camera 253, spiral scanning can be used to ensure that the cable surface is completely scanned without dead angles.

[0058] When the traditional static detection mode is adopted, only the transmission cable is required, and each industrial camera 253 performs corresponding image acquisition, and then AI is used to detect and analyze surface defects.

[0059] When it is necessary to remove or re-insert the cable from the access port, the gear ring 22 stops rotating first, and the power of the ratchet ring 31 is interrupted. The limit rod 324 is no longer subjected to the continuous pressure from the ratchet ring 31, and then the spring piece 3242 is reset, forcing the limit rod 324 to move away from the ratchet bar 3221. At this time, each positioning assembly 32 is no longer limited, and driven by each limit rod 324, the ratchet ring 31 and the gear ring 22 are pushed in the reverse direction to rotate, and the cable can be easily removed or re-inserted. It should be noted that the ratchet ring 31 and the gear ring 22 can ensure that each access port is aligned by rotating in the reverse direction.

[0060] In summary, the present invention realizes detection without dead angles through a rotary detection method, and adopts an adaptive positioning method to ensure the stable transportation and positioning accuracy of cables of different specifications. The present invention has the characteristics of high detection coverage, strong adaptability, and stable and reliable operation. Compared with the prior art, it can realize all-round detection of surface defects during the continuous transmission of cables, and solve the problem of radial shaking of cables during the detection process, improve detection accuracy and production efficiency, and take into account both dynamic and static scanning and acquisition methods, so that the detection flexibility is improved.
