Description

Technical Field

[0001] This invention relates to the technical field of detecting surface defects in cable sections, and in particular to a highly efficient detection device and method for detecting surface defects in cable sections. Background Technology

[0002] The structure of the cable short sections produced in a certain workshop is as follows: Figures 1-2 As shown, the length of the cable section 1 is 100~120cm. The cable section 1 includes a conductive copper core 2 and a sheath 3. The sheath 3 covers and fixes the outside of the conductive copper core 2 along the length direction of the conductive copper core 2. This type of cable section 1 is mainly used to be installed between the control box and electrical equipment to transmit the signals sent by the control box.

[0003] When the workers in the workshop produce a batch of such Figures 1-2 After the cable section 1 shown, and before supplying it to the power line laying construction team, it is necessary to inspect the surface defects of each cable section 1 [surface defects include bulges, cracks and pits on the sheath 3 of the cable section 1, which may be caused by non-standard manufacturing process], and after inspection, unqualified cable sections are separated from qualified cable sections, and qualified cable sections are then supplied to the power line laying construction team.

[0004] Workers in the workshop use, for example Figures 3-4 The visual inspection fixture shown is used to inspect the surface defects of a batch of cable short sections 1. The visual inspection fixture includes a pad, a positioning seat 4 fixed on the top surface of the pad, and a vertical plate 5. The top surface of the positioning seat 4 is provided with a strip groove 6 that runs through its left and right ends. A feed cylinder 7 is fixed on the vertical plate 5. The piston rod of the feed cylinder 7 runs through the vertical plate 5, and an L-plate is fixed on its extended end. A first CCD lens 8 facing the strip groove 6 is fixed in the horizontal part of the L-plate. The first CCD lens 8 is connected to the controller via a signal line.

[0005] The method by which workers use this visual inspection fixture to inspect the surface defects of a batch of cable short sections 1 in a material basket is as follows:

[0006] S1. The worker takes out a piece from the material basket. Figures 1-2 The cable section 1 to be tested is shown.

[0007] S2. The worker pushes cable section 1 from right to left into the slot 6, as follows: Figures 5-6 As shown, when the worker observes that the left end of the cable section 1 is just below the first CCD lens 8, the worker stops pushing the cable section 1. At this time, the right end of the cable section 1 is exposed outside the strip groove 6.

[0008] S3. The worker manually rotates the right end of cable section 1 so that cable section 1 rotates around its own axis within the slot 6. The direction of rotation of cable section 1 is as follows: Figure 7 As indicated by the solid arrow, this ultimately puts cable section 1 into a state of being ready for testing.

[0009] S4. The worker controls the piston rod of the feed cylinder 7 to extend to the right. The piston rod drives the L plate to move to the right. The L plate drives the first CCD lens 8 to move along the length of the cable section 1. During the movement, the first CCD lens 8 identifies the surface of the cable section 1 in real time. If the first CCD lens 8 identifies a surface defect on the cable section 1, the first CCD lens 8 sends an electrical signal to the controller. At this time, the worker determines that the cable section 1 is a defective cable section.

[0010] If the first CCD lens 8 moves directly above the right end of the cable section 1 and the first CCD lens 8 still does not send an electrical signal to the controller, it means that there are no surface defects on the surface of the cable section 1 being tested. At this time, the worker judges the cable section 1 to be a qualified cable section, and thus the detection of surface defects of a cable section 1 is finally completed.

[0011] S5. Workers can repeat steps S1 to S4 multiple times to perform surface defect detection on all cable sections 1 in a batch in the material basket.

[0012] However, while this visual inspection fixture can perform surface defect inspection on a batch of cable sections 1, the following technical shortcomings still emerge during actual operation:

[0013] I. In step S1, a worker needs to manually remove a cable section 1 to be inspected from the material basket. In step S2, the worker also needs to manually push the cable section 1 into the strip groove 6. In step S3, the worker also needs to manually rotate the cable section 1 to put it into the inspection state. The entire operation is done manually by the worker, and there are many steps involved. This not only increases the worker's workload, but also prolongs the subsequent inspection time for surface defects of the cable section 1, thereby reducing the inspection efficiency of surface defects of the cable section 1.

[0014] II. As can be seen from steps S1 to S3, only one cable section 1 can be inspected for surface defects at a time, while the number of cable sections 1 to be inspected in a batch is as high as 90. This method of inspection one after another takes a long time to complete the inspection of all surface defects of a batch of cable sections 1, which undoubtedly further reduces the inspection efficiency of surface defects of cable sections 1.

[0015] Therefore, there is an urgent need for a visual inspection device and method that can greatly reduce the workload of workers and greatly improve the efficiency of detecting surface defects in cable sections. Summary of the Invention

[0016] The purpose of this invention is to overcome the shortcomings of the prior art and provide an efficient detection device and method for detecting surface defects in cable sections.

[0017] The objective of this invention is achieved through the following technical solution: a high-efficiency detection device for detecting surface defects of cable sections, comprising an arched frame fixed on a workbench, and a material-retrieving component for automatically removing two cable sections to be tested is provided on the crossbeam of the arched frame.

[0018] The material handling assembly includes a material handling cylinder fixed to the top surface of the arched frame beam. The piston rod of the material handling cylinder passes downward through the beam and a concave part is fixed to the extended end. A material handling frame is fixed to the bottom end of the left and right side walls of the concave part. A baffle is fixed to the top surface of the two material handling frames. The outer end face of the baffle is flush with the outer end face of the material handling frame. The bottom wall of the inner cavity of the two material handling frames is an inward and downward inclined surface. A bidirectional cylinder is fixed to the bottom surface of the concave part. A sealing plate is fixed to the two piston rods of the bidirectional cylinder. The two sealing plates abut against the right end face of the two material handling frames to seal the inner cavity of the material handling frames.

[0019] Both material picking frames are provided with a storage channel steel fixed to the bottom surface of the arched frame beam on the outer side. Both storage channel steels are inclined inward and downward. The inner end face of the storage channel steel is in contact with the outer end face of the corresponding material picking frame, and the groove of the storage channel steel is connected to the inner cavity of the material picking frame.

[0020] Each of the two storage channel steels is equipped with a positioning and identification component for locating cable sections and detecting surface defects of the cable sections. The workbench is also equipped with two turnover components. The left turnover component is used to transport one cable section to the positioning station of the left positioning and identification component, while the right turnover component is used to transport another cable section to the positioning station of the right positioning and identification component.

[0021] Multiple hangers are welded to the top surface of the storage channel steel, and the top of the hangers is welded to the crossbeam of the arched frame to suspend the storage channel steel.

[0022] The two picking frames of the picking assembly are symmetrical about the picking cylinder, and the two sealing plates are also symmetrical about the picking cylinder.

[0023] The longitudinal width of the storage channel steel groove of the material receiving component is greater than the length of the cable section.

[0024] The positioning and identification component located on the left side includes a connecting seat welded to the steel bottom surface of the left storage trough and a strip support plate fixed to the bottom surface of the connecting seat. A hinge seat A is fixed on the top surface of the strip support plate and at its left and right ends. A bent component extending below the strip support plate is hinged to each of the two hinge seats A. A positioning cylindrical head is fixed on the inner end face of the extension end of each of the two bent components. Two positioning cylinders are also fixed on the top surface of the strip support plate. The two positioning cylinders correspond to the two bent components respectively. A connecting rod A is hinged to the piston rod of the positioning cylinder. The other end of the connecting rod A is hinged to the upper end of the bent component.

[0025] A linear cylinder A is fixed on the bottom surface of the strip support plate, and a second CCD lens is fixed on the bottom surface of the moving stage A of the linear cylinder A.

[0026] The turnover assembly on the left includes a linear cylinder B fixed on the workbench surface. A servo motor is fixed on the top surface of the moving table B of the linear cylinder B. An eccentric plate is fixed on the output shaft of the servo motor. A hinge seat B is fixed on the top surface of the eccentric plate. A platform is hinged to the hinge seat B. Two support plates are fixed on the top surface of the platform. Hollow rollers are rotatably mounted on the rear end faces of the two support plates via a rotating shaft. A drive motor is fixed on the front end face of one of the support plates. The output shaft of the drive motor is connected to the rotating shaft of the hollow roller.

[0027] A vertical cylinder is also fixed on the bottom surface of the eccentric plate. The piston rod of the vertical cylinder passes through the eccentric plate upward, and a connecting rod B is hinged to the extended end. The other end of the connecting rod B is hinged to the bottom surface of the platform.

[0028] Both hollow rollers are arranged longitudinally, and a gap is left between the two hollow rollers.

[0029] The vision inspection device also includes a controller, which is electrically connected to the material handling cylinder, the bidirectional cylinder, the positioning cylinder, the linear cylinder A, the linear cylinder B, the servo motor, the drive motor, and the second CCD lens via signal lines.

[0030] An efficient detection method for detecting surface defects in cable sections includes the following steps:

[0031] S1. Pre-place multiple cable sections to be tested in the storage channel steel on the left: The worker places multiple cable sections into the groove of the storage channel steel on the left side of the material picking component in sequence. The multiple cable sections roll down the storage channel steel under their own weight. The first cable section placed in just rolls into the inner cavity of the left picking frame and is blocked by the left sealing plate of the picking component. Meanwhile, the cable sections placed in later remain in the groove of the left storage channel steel.

[0032] S2. The worker repeats the operation of step S1 to pre-place multiple cable sections to be tested in the storage channel steel on the right.

[0033] S3. Remove two cable sections to be tested at once. The specific operating steps are as follows:

[0034] S31. The piston rod of the picking cylinder of the material picking assembly extends downward, and the piston rod drives the concave part to move downward. The concave part drives the bidirectional cylinder, two sealing plates, two picking frames and two baffles to move downward synchronously. Among them, the two picking frames drive the cable shorts that have rolled in to move downward synchronously. At the same time, the baffles gradually block the grooves of the storage channel steel. When the piston rod of the picking cylinder is fully extended, the two picking frames are staggered from the two storage channels steel respectively. At the same time, the two baffles block the grooves of the two storage channels steel respectively to prevent the remaining cable shorts in the storage channels steel from rolling to the outside of the storage channels steel.

[0035] S32. Both piston rods of the bidirectional cylinder controlling the material taking component retract inward, and the two piston rods drive the sealing plates connected to them to move inward. The sealing plates gradually move away from the material taking frame. When the two piston rods of the bidirectional cylinder are fully retracted, the cable section located in the left material taking frame rolls out to the right along the slope of the material taking frame. After rolling out, the cable section on the left side just rolls into the area enclosed by the two hollow rollers of the left turnover component.

[0036] Meanwhile, the cable section located in the right-side picking frame rolls out to the left along the inclined surface of the picking frame. After rolling out, the cable section on the right side just rolls into the area enclosed by the two hollow rollers of the right-side turnover component, thus finally realizing the one-time removal of two cable sections to be tested.

[0037] S4. After removing two cable sections to be tested at once, first control both piston rods of the bidirectional cylinder to extend, and the piston rods drive the sealing plates connected to them to move outward, so that the sealing plates seal the inner cavity of the material picking frame again; then control the piston rod of the material picking cylinder to retract upward, so that the inner cavities of the two material picking frames are connected to the grooves of the two storage channel steels again. At this time, the cable sections in the storage channel steel roll into the inner cavity of the material picking frame, in preparation for the second material picking.

[0038] S5. Using two turnover components, the two cable sections are respectively transported to the positioning stations of the two positioning and identification components. The specific operation steps are as follows:

[0039] S51. Control the linear cylinder B of the left turnover component to move the moving table B to the left. The moving table B drives the servo motor, eccentric plate, vertical cylinder and hollow roller to move to the left in sync, which in turn drives the cable section on the hollow roller to move to the left in sync.

[0040] S52. When the moving table B of the linear cylinder B moves to the left limit position of the linear cylinder B, the servo motor of the left turnover component is started. The servo motor drives the eccentric plate to rotate in the horizontal direction. The eccentric plate drives the vertical cylinder and the hollow roller to rotate synchronously in the horizontal direction, which in turn drives the cable section on the hollow roller to rotate synchronously in the horizontal direction. When the cable section rotates 90°, the controller controls the servo motor to turn off, thereby using the left turnover component to transport the cable section that has rolled onto it to the positioning station of the left positioning and identification component.

[0041] S53. The worker repeats steps S51 to S52 once, and then uses the right-side turnover component to transport the cable section that has rolled onto it to the positioning station of the right-side positioning and identification component.

[0042] S6. Use two positioning and identification components to locate the two cable sections respectively. The specific operation steps are as follows:

[0043] S61. The piston rods of the two positioning cylinders of the positioning recognition component on the left are extended. The piston rods drive the connecting rod A to move synchronously. The connecting rod A drives the bending part to rotate around the hinge seat A. The bending part drives the positioning cylindrical head to move toward the end face of the cable section. When the piston rods of the two positioning cylinders are fully extended, the two positioning cylindrical heads contact the left and right end faces of the cable section respectively. Thus, the positioning recognition component on the left is used to position the cable section on the left. At this time, the second CCD lens of the positioning recognition component on the left is facing directly above the left end of the cable section.

[0044] S62. The worker repeats step S61 once to locate the right cable section using the positioning and recognition component on the right. At this time, the second CCD lens of the positioning and recognition component on the right is directly above the right end of the cable section.

[0045] S7. Surface defect detection is performed on the two cable sections using two positioning and identification components. The specific operation steps are as follows:

[0046] S71. Start the drive motor of the left-side turnover component. The drive motor drives the hollow roller connected to it to rotate synchronously. The hollow roller drives the cable section restricted between the two positioning cylinders to rotate in the opposite direction. At this time, the cable section is in the detection state.

[0047] S72. The linear cylinder A of the positioning and recognition component on the left moves the moving stage A to the right along the length of the cable section. The moving stage A drives the second CCD lens to move to the right synchronously. During the movement, the second CCD lens identifies the surface of the cable section in real time. If the second CCD lens detects a surface defect in the cable section, it sends an electrical signal to the controller. At this time, the controller determines that the detected cable section is a defective cable section. The controller's next operation is:

[0048] S721, the controller controls the linear cylinder A to close, and then controls the drive motor to close; then it controls the piston rods of both positioning cylinders to retract, so that the two positioning cylindrical heads are separated from the defective cable short section;

[0049] S722, The controller controls the piston rod of the vertical cylinder of the left turnover component to retract downwards. The piston rod drives the connecting rod B to move downwards. The connecting rod B drives the platform to rotate outwards relative to the hinge seat B. The platform drives the hollow roller to rotate outwards synchronously. The hollow roller drives the unqualified cable short section to rotate outwards synchronously. At this time, the worker removes the unqualified cable short section that is rotating outwards from the hollow roller.

[0050] If the second CCD lens does not send an electrical signal to the controller after moving to the right limit position of the linear cylinder A, it indicates that there are no surface defects on the surface of the cable section. At this time, the controller determines that the tested cable section is a qualified cable section, and the controller's next operation is:

[0051] S723, the controller controls the linear cylinder A to close, and then controls the drive motor to close; then it controls the piston rods of both positioning cylinders to retract, so that the two positioning cylindrical heads are separated from the cable short section;

[0052] S724. The controller controls the piston rod of the vertical cylinder of the left turnover component to extend upward. The piston rod drives the connecting rod B to move upward. The connecting rod B drives the platform to rotate inward relative to the hinge seat B. The platform drives the hollow roller to rotate inward synchronously. The hollow roller drives the qualified cable short section to rotate inward synchronously. At this time, the worker takes the qualified cable short section that is rotating inward from the hollow roller, thereby using the positioning and identification component on the left to perform surface defect detection on the cable short section on the left.

[0053] S73. The worker repeats steps S71 to S72 once, and can use the positioning and identification component on the right to detect surface defects in the cable section on the right.

[0054] S8. Workers can repeat steps S3 to S7 multiple times to perform surface defect detection on all cable sections in a batch in the workshop.

[0055] The present invention has the following advantages: it greatly reduces the workload of workers and greatly improves the efficiency of detecting surface defects in cable sections. Attached Figure Description

The two material handling frames 14 of the material handling assembly 11 are symmetrical about the material handling cylinder 12, and the two sealing plates 19 are also symmetrical about the material handling cylinder 12.

[0096] Each of the two material picking frames 14 has a storage channel steel 20 fixed to the bottom surface of the crossbeam of the arched frame 10. Both storage channel steels 20 are inclined inward and downward. The inner end face of the storage channel steel 20 is in contact with the outer end face of the corresponding material picking frame 14, and the groove 21 of the storage channel steel 20 is connected to the inner cavity 16 of the material picking frame 14.

[0098] The positioning and identification component 22 located on the left side includes a connecting seat 25 welded to the bottom surface of the left storage channel steel 20, and a strip support plate 26 fixed to the bottom surface of the connecting seat 25. A hinge seat A is fixed to the top surface of the strip support plate 26 and at its left and right ends. A bent piece 27 extending below the strip support plate 26 is hinged to each of the two hinge seats A. A positioning cylindrical head 28 is fixed to the inner end face of the extension end of each of the two bent pieces 27. Two positioning cylinders 29 are also fixed to the top surface of the strip support plate 26. The two positioning cylinders 29 correspond to the two bent pieces 27 respectively.

A linear cylinder A31 is fixed to the bottom surface of the strip support plate 26. A second CCD lens 32 is fixed to the bottom surface of the moving stage A of the linear cylinder A31.

[0099] The left-side turnover assembly 23 includes a linear cylinder B33 fixed to the workbench 9. A servo motor 34 is fixed to the top surface of the moving platform B of the linear cylinder B33.

[0101] An efficient detection method for detecting surface defects in cable sections includes the following steps:

[0102] S1. Several cable sections 1 to be tested are pre-placed in the storage channel steel 20 on the left side: The worker sequentially places several such sections into the groove 21 of the storage channel steel 20 on the left side of the material handling assembly 11. Figures 1-2 As shown, multiple cable sections 1 roll down the storage channel 20 under their own weight. The first cable section 1 placed in the channel lands precisely in the inner cavity 16 of the left-side material picking frame 14. Figure 20 As shown, it is blocked by the left sealing plate 19 of the material taking component 11, and the cable short section 1 that is subsequently put in is all left in the groove 21 of the left storage channel steel 20.

[0103] S2. The worker repeats step S1 to pre-place multiple cable sections 1 to be tested within the storage channel 20 on the right side, such as... Figure 21 As shown;

[0104] S3. Remove two cable sections 1 to be tested at once. The specific operating steps are as follows:

[0105] S31, the piston rod of the picking cylinder 12 of the material picking assembly 11 extends downward, driving the concave part 13 to move downward. The concave part 13 drives the bidirectional cylinder 18, the two sealing plates 19, the two picking frames 14, and the two baffles 15 to move downward synchronously. Among them, the two picking frames 14 drive the cable stub 1 that has rolled inside to move downward synchronously. At the same time, the baffles 15 gradually block the groove 21 of the storage channel steel 20. When the piston rod of the picking cylinder 12 is fully extended, the two picking frames 14 are staggered from the two storage channel steels 20 respectively. Figure 22 As shown, at the same time, the two baffles 15 respectively block the grooves 21 of the two storage channel steels 20 to prevent the remaining cable sections inside the storage channel steels 20 from rolling to the outside of the storage channel steels 20.

[0106] S32, the two piston rods of the bidirectional cylinder 18 of the control assembly 11 retract inward, and the two piston rods drive the sealing plate 19 connected to them to move inward. The sealing plate 19 gradually moves away from the material picking frame 14, such as... Figure 23 As shown; when the two piston rods of the bidirectional cylinder 18 are fully retracted, the cable section 1 located in the left-side material picking frame 14 rolls out to the right along the inclined surface 17 of the material picking frame 14, and the rolling direction of the cable section 1 is as follows. Figure 23 As shown by the middle arrow, after rolling out, the left cable section 1 falls exactly into the area enclosed by the two hollow rollers 39 of the left turnover assembly 23, as shown. Figure 24 As shown;

[0107] Simultaneously, the cable section 1 located in the right-side picking frame 14 rolls out to the left along the inclined surface 17 of the picking frame 14. After rolling out, the cable section 1 on the right side falls exactly into the area enclosed by the two hollow rollers 39 of the right-side turnover assembly 23, such as... Figure 24 As shown, this ultimately enabled the removal of two cable sections 1 to be tested at once;

[0108] S4. After removing two cable sections 1 to be tested at once, first control both piston rods of the bidirectional cylinder 18 to extend, and the piston rods drive the sealing plates 19 connected to them to move outward, so that the sealing plates 19 seal the inner cavity of the material picking frame 14 again; then control the piston rod of the material picking cylinder 12 to retract upward, so that the inner cavities 16 of the two material picking frames 14 are connected again to the grooves 21 of the two storage channel steels 20. At this time, the cable sections in the storage channel steels 20 roll into the inner cavity 16 of the material picking frame 14, in preparation for the second material picking. Figure 25 As shown;

[0109] S5. Using two turnover components 23, the two cable sections 1 are respectively transported to the positioning stations of the two positioning and identification components 22. The specific operation steps are as follows:

[0110] S51, the linear cylinder B33 of the left-side turnover assembly 23 controls the moving table B to move to the left. The moving table B drives the servo motor 34, eccentric plate 35, vertical cylinder 41, and hollow roller 39 to move to the left synchronously, thereby driving the cable section 1 on the hollow roller 39 to move to the left synchronously. Figure 26 As shown;

[0111] S52. When the moving platform B of the linear cylinder B33 moves to the left limit position of the linear cylinder B33, the servo motor 34 of the left-side turnover assembly 23 is started. The servo motor 34 drives the eccentric plate 35 to rotate horizontally. The eccentric plate 35 drives the vertical cylinder 41 and the hollow roller 39 to rotate synchronously in the horizontal direction, thereby driving the cable section 1 on the hollow roller 39 to rotate synchronously in the horizontal direction. When the cable section 1 rotates 90°, the controller controls the servo motor 34 to turn off, thus using the left-side turnover assembly 23 to transport the cable section 1 that has rolled onto it to the positioning station of the left-side positioning and identification assembly 22. Figure 27 As shown;

[0112] S53. The worker repeats steps S51-S52 once, and then uses the right-side turnover component 23 to transport the cable section 1 that has rolled onto it to the positioning station of the right-side positioning and identification component 22. Figure 27 As shown;

[0113] S6. The two cable sections 1 are located using the two positioning and identification components 22 respectively. The specific operation steps are as follows:

[0114] S61. The piston rods of the two positioning cylinders 29 of the positioning identification component 22 on the left side are extended. The piston rods drive the connecting rod A30 to move synchronously. The connecting rod A30 drives the bending part 27 to rotate around the hinge seat A. The bending part 27 drives the positioning cylindrical head 28 to move towards the end face of the cable section 1. When the piston rods of the two positioning cylinders 29 are fully extended, the two positioning cylindrical heads 28 contact the left and right end faces of the cable section 1 respectively, thereby using the positioning identification component 22 on the left side to position the cable section 1 on the left side. Figure 28 As shown, at this time, the second CCD lens 32 of the positioning and recognition component 22 on the left is directly above the left end of the cable section 1;

[0115] S62. The worker repeats step S61 once, and can use the positioning and identification component 22 on the right to position the cable section 1 on the right. Figure 28 As shown, at this time, the second CCD lens 32 of the positioning and recognition component 22 on the right side is directly above the right end of the cable section 1.

[0116] S7. Surface defect detection is performed on the two cable sections 1 using two positioning and identification components 22 respectively. The specific operation steps are as follows:

[0117] S71. The drive motor 40 of the left-side rotating assembly 23 is started. The drive motor 40 drives the hollow roller 39 connected to it to rotate synchronously. The hollow roller 39 drives the cable section 1, which is restricted between the two positioning cylindrical heads 28, to rotate in the opposite direction. At this time, the cable section 1 is in the detection state. The rotation direction of the cable section 1 is as follows: Figure 29 As indicated by the middle arrow;

[0118] S72. The linear cylinder A31 of the positioning and recognition component 22 on the left controls the moving stage A to move to the right along the length of the cable section 1. The moving stage A drives the second CCD lens 32 to move to the right synchronously. During the movement, the second CCD lens 32 identifies the surface of the cable section 1 in real time. If the second CCD lens 32 identifies a surface defect in the cable section 1, it sends an electrical signal to the controller. At this time, the controller determines that the detected cable section is a defective cable section 43. The controller's next operation is:

[0119] S721, the controller controls the linear cylinder A31 to close, and then controls the drive motor 40 to close; then controls the piston rods of the two positioning cylinders 29 to retract, so that the two positioning cylindrical heads 28 are separated from the defective cable short section 43;

[0120] S722, the controller controls the piston rod of the vertical cylinder 41 of the left-side turnover assembly 23 to retract downwards. The piston rod drives the connecting rod B42 to move downwards, and the connecting rod B42 drives the platform 37 to rotate outwards relative to the hinge seat B36. The platform 37 drives the hollow roller 39 to rotate outwards synchronously, and the hollow roller 39 drives the defective cable short section 43 to rotate outwards synchronously. Figure 30 As shown, at this point, the worker removes the defective cable section 43, which is rotating outward, from the hollow drum 39;

[0121] If the second CCD lens 32 moves to the right limit position of the linear cylinder A31 and still does not send an electrical signal to the controller, it means that there are no surface defects on the surface of the cable section 1. At this time, the controller determines that the cable section being tested is a qualified cable section 44, and the controller's next operation is:

[0122] S723, the controller controls the linear cylinder A31 to close, and then controls the drive motor 40 to close; then controls the piston rods of the two positioning cylinders 29 to retract, so that the two positioning cylindrical heads 28 are separated from the cable section 1;

[0123] S724, the controller controls the piston rod of the vertical cylinder 41 of the left-side turnover assembly 23 to extend upward. The piston rod drives the connecting rod B42 to move upward. The connecting rod B42 drives the platform 37 to rotate inward relative to the hinge seat B36. The platform 37 drives the hollow roller 39 to rotate inward synchronously. The hollow roller 39 drives the qualified cable short section 44 to rotate inward synchronously. Figure 31 As shown, at this time, the worker removes the qualified cable section 44 that rotates inward from the hollow roller 39, thereby using the positioning and identification component 22 on the left to perform surface defect detection on the cable section 1 on the left.

[0124] S73. The worker repeats steps S71 to S72 once, and can use the positioning and identification component 22 on the right to perform surface defect detection on the cable section 1 on the right.

[0125] S8. Workers can repeat steps S3 to S7 multiple times to perform surface defect detection on all cable sections 1 in a batch in the workshop.

[0126] As can be seen from steps S3 to S7, the worker can automatically remove the cable section 1 by sequentially operating the picking cylinder 12 and the bidirectional cylinder 18 of the picking component 11; then, by sequentially operating the linear cylinder B33 and the servo motor 34 of the turnover component 23, the cable section 1 can automatically enter the positioning station of the positioning and identification component 22; then, the drive motor 40 of the turnover component 23 is started to make the cable section 1 rotate around its own axis, and finally the cable section 1 is automatically and quickly put into the inspection state.

[0127] Therefore, it can be seen that this visual inspection device is superior to... Figures 3-7 The detection method shown eliminates the need for workers to manually remove a cable section 1 to be inspected from the basket, push it into the slot 6, or rotate it to put it in the inspection-ready state. Instead, the cable section 1 is automatically and quickly brought into the inspection-ready state through the coordinated operation of the material handling component 11, the turnover component 23, and the positioning and identification component 22. This not only greatly reduces the workload of workers but also eliminates the inspection process, thereby shortening the inspection time for surface defects of the cable section 1 and significantly improving the inspection efficiency.

[0128] Furthermore, in step S3, the material handling component 11 first removes two cable sections 1 at once. Then, in steps S4-S7, through the coordinated operation of the left-side turnover component 23 and the left-side positioning and identification component 22, and the coordinated operation of the right-side turnover component 23 and the right-side positioning and identification component 22, surface defect detection can be performed on the two removed cable sections 1 respectively. Therefore, it can be seen that this visual inspection device, compared to traditional methods used in workshops, offers significant advantages. Figures 3-7 The detection method shown eliminates the need for workers to inspect each cable section one by one, thus enabling the entire batch of cable sections 1 to be inspected in a short time, thereby greatly improving the efficiency of detecting surface defects in cable sections 1.

7. A highly efficient detection method for detecting surface defects in cable sections, employing the highly efficient detection device for detecting surface defects in cable sections as described in claim 6, characterized in that: It includes the following steps: S1. Multiple cable sections (1) to be tested are pre-placed in the storage channel steel (20) on the left side: The worker puts multiple cable sections (1) into the groove (21) of the storage channel steel (20) on the left side of the picking component (11) in sequence. The multiple cable sections (1) roll down along the storage channel steel (20) under their own weight. The first cable section (1) is placed into the inner cavity (16) of the picking frame (14) on the left side and is blocked by the sealing plate (19) on the left side of the picking component (11). Meanwhile, the cable sections (1) placed later are all left in the groove (21) of the storage channel steel (20) on the left side. S2. The worker repeats the operation of step S1 to pre-place multiple cable sections (1) to be tested in the storage channel steel (20) on the right. S3. Remove two cable sections (1) to be tested at once. The specific operation steps are as follows: S31. The piston rod of the picking cylinder (12) of the picking assembly (11) extends downward, and the piston rod drives the concave part (13) to move downward. The concave part (13) drives the bidirectional cylinder (18), two sealing plates (19), two picking frames (14) and two baffles (15) to move downward synchronously. Among them, the two picking frames (14) drive the cable short sections (1) that have rolled into the container to move downward synchronously. At the same time, the baffles (15) gradually block the grooves (21) of the storage channel steel (20). When the piston rod of the picking cylinder (12) is fully extended, the two picking frames (14) are staggered from the two storage channel steels (20) respectively. At the same time, the two baffles (15) block the grooves (21) of the two storage channel steels (20) respectively to prevent the remaining cable short sections in the storage channel steel (20) from rolling to the outside of the storage channel steel (20). S32. The two piston rods of the bidirectional cylinder (18) of the control assembly (11) retract inward, and the two piston rods drive the sealing plate (19) connected to them to move inward. The sealing plate (19) gradually moves away from the material picking frame (14). When the two piston rods of the bidirectional cylinder (18) are fully retracted, the cable section (1) located in the left material picking frame (14) rolls out to the right along the inclined surface (17) of the material picking frame (14). When it rolls out, the cable section (1) on the left side just rolls into the area enclosed by the two hollow rollers (39) of the left turnover assembly (23). Meanwhile, the cable section (1) located in the right picking frame (14) rolls out to the left along the inclined surface (17) of the picking frame (14). After rolling out, the cable section (1) on the right side just rolls into the area enclosed by the two hollow rollers (39) of the right turnover component (23), thus finally realizing the one-time removal of two cable sections (1) to be tested. S4. After taking out two cable sections (1) to be tested at once, first control the two piston rods of the bidirectional cylinder (18) to extend, and the piston rods drive the sealing plates (19) connected to them to move outward, so that the sealing plates (19) can seal the inner cavity of the picking frame (14) again; then control the piston rod of the picking cylinder (12) to retract upward, so that the inner cavity (16) of the two picking frames (14) can be connected to the groove (21) of the two storage channel steels (20) again. At this time, the cable sections in the storage channel steel (20) roll into the inner cavity (16) of the picking frame (14) to prepare for the second picking. S5. Using two turnover components (23), the two cable sections (1) are respectively transported to the positioning stations of the two positioning and identification components (22). The specific operation steps are as follows: S51, the linear cylinder B (33) of the left-side turnover component (23) moves the moving table B to the left. The moving table B drives the servo motor (34), eccentric plate (35), vertical cylinder (41), and hollow roller (39) to move to the left in sync, thereby driving the cable section (1) on the hollow roller (39) to move to the left in sync. S52. When the moving table B of the linear cylinder B (33) moves to the left limit position of the linear cylinder B (33), the servo motor (34) of the left turnover component (23) is started. The servo motor (34) drives the eccentric plate (35) to rotate in the horizontal direction. The eccentric plate (35) drives the vertical cylinder (41) and the hollow roller (39) to rotate synchronously in the horizontal direction, thereby driving the cable section (1) on the hollow roller (39) to rotate synchronously in the horizontal direction. When the cable section (1) rotates 90°, the controller controls the servo motor (34) to turn off, thereby using the left turnover component (23) to transport the cable section (1) that has rolled onto it to the positioning station of the left positioning identification component (22). S53. The worker repeats the operation of steps S51~S52 once, and can use the right-side turnover component (23) to transport the cable section (1) that has rolled on it to the positioning station of the right-side positioning identification component (22). S6. Use two positioning and identification components (22) to locate the two cable sections (1) respectively. The specific operation steps are as follows: S61. The piston rods of the two positioning cylinders (29) of the positioning recognition component (22) on the left side are extended. The piston rods drive the connecting rod A (30) to move synchronously. The connecting rod A (30) drives the bending part (27) to rotate around the hinge seat A. The bending part (27) drives the positioning cylinder head (28) to move toward the end face of the cable section (1). When the piston rods of the two positioning cylinders (29) are fully extended, the two positioning cylinder heads (28) contact the left and right end faces of the cable section (1) respectively. Thus, the positioning recognition component (22) on the left side is used to position the cable section (1) on the left side. At this time, the second CCD lens (32) of the positioning recognition component (22) on the left side is directly above the left end of the cable section (1). S62.

Start the drive motor (40) of the left-side turnover component (23). The drive motor (40) drives the hollow roller (39) connected to it to rotate synchronously. The hollow roller (39) drives the cable section (1) restricted between the two positioning cylindrical heads (28) to rotate in the opposite direction. At this time, the cable section (1) is in the state of waiting to be detected. S72. The linear cylinder A (31) of the positioning and identification component (22) on the left moves the moving stage A to the right along the length of the cable section (1). The moving stage A drives the second CCD lens (32) to move to the right synchronously. During the movement, the second CCD lens (32) identifies the surface of the cable section (1) in real time. If the second CCD lens (32) identifies that there is a surface defect in the cable section (1), the second CCD lens (32) sends an electrical signal to the controller. At this time, the controller determines that the cable section being tested is an unqualified cable section (43). The next operation of the controller is: S721, the controller controls the linear cylinder A (31) to close, and then controls the drive motor (40) to close; then controls the piston rods of the two positioning cylinders (29) to retract so that the two positioning cylindrical heads (28) are separated from the defective cable short section (43); S722, the controller controls the piston rod of the vertical cylinder (41) of the left turnover component (23) to retract downwards, the piston rod drives the connecting rod B (42) to move downwards, the connecting rod B (42) drives the platform (37) to rotate outwards relative to the hinge seat B (36), the platform (37) drives the hollow roller (39) to rotate outwards synchronously, the hollow roller (39) drives the unqualified cable short section (43) to rotate outwards synchronously, at this time, the worker removes the unqualified cable short section (43) rotating outwards from the hollow roller (39); If the second CCD lens (32) moves to the right limit position of the linear cylinder A (31) and the second CCD lens (32) still does not send an electrical signal to the controller, it means that there are no surface defects on the surface of the cable section (1). At this time, the controller determines that the cable section being tested is a qualified cable section (44). The next operation of the controller is: S723, the controller controls the linear cylinder A (31) to close, and then controls the drive motor (40) to close; then controls the piston rods of the two positioning cylinders (29) to retract so that the two positioning cylindrical heads (28) are separated from the cable short section (1); S724, the controller controls the piston rod of the vertical cylinder (41) of the left turnover component (23) to extend upward, the piston rod drives the connecting rod B (42) to move upward, the connecting rod B (42) drives the platform (37) to rotate inward relative to the hinge seat B (36), the platform (37) drives the hollow roller (39) to rotate inward synchronously, the hollow roller (39) drives the qualified cable section (44) to rotate inward synchronously, at this time, the worker takes the qualified cable section (44) rotating inward from the hollow roller (39), thereby using the positioning and identification component (22) on the left to perform surface defect detection on the cable section (1) on the left. S73. The worker repeats the operation of steps S71~S72 once, and can use the positioning and identification component (22) on the right to perform surface defect detection on the cable section (1) on the right.
