Description

Technical Field

[0001] The present invention relates to the technical field of optical cable skeleton groove material detection, and in particular to an online detection device and method for defects in a skeleton groove of a skeleton type optical cable. Background Art

[0002] A skeleton-type optical cable is suitable for relay networks. Its structure utilizes a skeleton and central reinforcement as support elements to ensure the cable's mechanical and thermal properties. The skeleton trough, a specific structure within the skeleton-type cable, houses information carriers such as optical fiber ribbons and provides protection and positioning for the optical fibers. The shape and size of the skeleton trough directly impact the placement and protection of the optical fibers. Online testing can promptly identify defects within the skeleton trough, allowing for early adjustment of process parameters or implementation of appropriate measures during production.

[0003] Currently, when skeleton-type optical cable skeleton troughs are inspected online, plate-type inspection equipment is used to detect whether the pitch of the skeleton trough is accurate. The skeleton needs to pass through the central through hole of the inspection mold. When the skeleton is subsequently translated through the inspection mold, the skeleton trough and the inspection boss on the inspection mold cooperate with each other, which will drive the inspection mold to rotate, and then detect the pitch of the skeleton groove.

[0004] However, the skeleton width of the skeleton-type optical cable is generally small. When passing the skeleton through the detection mold, the staff needs to concentrate on aligning the skeleton groove with the detection boss inside the detection mold. When the skeleton groove and the detection boss are not aligned, the staff needs to concentrate on carefully observing the relative position of the skeleton groove and the detection boss, and constantly fine-tune the angle of the detection mold. The process is cumbersome and time-consuming, which affects the detection efficiency.

[0005] Therefore, we propose an online detection device and method for defects in the skeleton groove of a skeleton optical cable in order to solve the problems raised in the above background technology. Summary of the Invention

[0016] A use method of an online detection device for defects in a skeleton groove of a skeleton type optical cable, comprising the following steps: S1. The camera captures the position of the micro clamping claw and the detection boss. When the micro clamping claw and the detection boss are misaligned, the PLC controller starts the adjustment motor to drive the reinforcement plate, micro clamping claw, and alignment rail to rotate. When the micro clamping claw is aligned with one of the detection bosses, the adjustment motor is turned off. S2. Start the first electric push rod to push the fixed plate to the left, so that the clamping table and the alignment rail pass through the detection mold body. At the same time, two of the detection bosses slide into the two alignment rails. Start the micro cylinder to push the connecting block and the hexagonal ring to move. Under the limit of the fixed rod, the micro clamping claw opens; S3. After the optical cable skeleton passes through the needle-type detection mechanism, start the two electric push rods to push the two arc-shaped clamps to move relative to each other, clamping one end of the skeleton; S4. When the camera captures that the micro clamping claw is misaligned with the frame groove, the adjustment motor is started to drive the micro clamping claw, the alignment rail, and the detection boss to rotate together so that the micro clamping claw is aligned with the frame groove. The micro cylinder is started again to drive the micro cylinder to close and firmly grasp one end of the frame. S5. Start the electric push rod again to release the clamping of the skeleton, then start the first electric push rod again to pull the skeleton out of the inside of the detection mold body, and at the same time, the detection boss accurately slides into the skeleton groove, then the micro clamping claw releases the clamping of the skeleton, and the second electric push rod drives the skeleton pulling assembly to move upward and reset; S6. When the optical cable skeleton is driven by an external power device to move, it first passes through a needle-type detection mechanism, where a needle-type scanning laser radar probe scans the skeleton groove to obtain the contour information of the inner wall of the skeleton groove and detects microscopic defects on the inner wall of the skeleton groove; S7. Then, after passing through the plate-type detection mechanism, the skeleton groove cooperates with the detection boss inside the detection mold body, which drives the detection mold body to rotate, generates corresponding pitch values ​​and other related parameters, and detects whether there are defects such as inaccurate pitch, deformation, and incomplete structure in the skeleton groove.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present invention is used, start the first electric push rod to push the fixed plate to the left, so that the clamping table and the alignment rail pass through the detection mold body. Start the micro cylinder to drive the micro clamping claw to open. When the camera captures that the micro clamping claw is misaligned with the skeleton groove, start the adjustment motor to drive the micro clamping claw, the alignment rail and the detection boss to rotate together, so that the micro clamping claw is aligned with the skeleton groove. Start the micro cylinder again, drive the micro cylinder to close, and firmly grasp one end of the skeleton. The first electric push rod is started again to pull the skeleton out from the inside of the detection mold body, and at the same time, the detection boss slides accurately into the skeleton groove. Under the action of the skeleton pulling and pulling assembly, the effect of automatic alignment and positioning is achieved, which facilitates the skeleton to pass through the detection mold body smoothly. There is no need for staff to concentrate on careful observation, nor is there any need to repeatedly adjust the smaller detection mold body, saving time and manpower and improving detection efficiency.

[0018] 2. When the present invention is used, the position images of the micro clamping claw and the detection boss are collected through the camera. When the micro clamping claw is staggered with the detection boss, the PLC controller will first start the adjustment motor to drive the reinforcement plate, micro clamping claw and alignment rail to rotate. When the micro clamping claw is aligned with one of the detection bosses, the adjustment motor is turned off to realize the positioning of the micro clamping claw, alignment rail and detection boss. With the cooperation of the detection boss and the alignment rail, the subsequent alignment and positioning of the skeleton groove, micro clamping claw and detection boss are facilitated.

[0019] 3. When the present invention is used, during the movement of the optical cable skeleton, it passes through a needle-type detection mechanism, and uses a needle-type scanning laser radar probe to scan the skeleton groove, obtain the contour information of the inner wall of the skeleton groove, and detect the microscopic defects of the inner wall of the skeleton groove. Then, it passes through a plate-type detection mechanism to drive the detection mold body to rotate, generate corresponding pitch values ​​and other related parameters, and detect whether the skeleton groove has defects such as inaccurate pitch, deformation, and incomplete structure. The detection component adopts a combination of a needle-type detection mechanism and a plate-type detection mechanism. The needle-type detection can accurately measure and detect the local details of the skeleton groove, while the plate-type detection can grasp the shape, size, pitch and other parameters of the skeleton groove from the overall perspective. The combination of the two can complement each other, more comprehensively and accurately detect various defects in the skeleton groove, realize comprehensive detection of multiple parameters of the skeleton groove, more accurately evaluate the quality and performance of the skeleton groove, and improve detection efficiency and accuracy.

Electric push rods 503 are fixedly installed on both sides of the clamping seat 502. One end of the two electric push rods 503 is fixedly installed with an arc clamp 505. A supporting top block 504 is fixedly installed on the bottom surface of the clamping seat 502. A clamping frame 501 is fixedly installed on both sides of the bottom of the clamping seat 502. The top of the second electric push rod 202 is fixedly installed at the center of the internal top surface of the mounting frame 201. Spring telescopic rods 203 are fixedly installed on both sides of the internal top surface of the mounting frame 201. The bottom ends of the two spring telescopic rods 203 are fixedly installed on both sides of the top of the moving frame 204. The bottoms of the two mounting frames 201 are fixedly installed on the top of the base 101 near the plate-type detection mechanism 107.

[0024] In this embodiment, when in use, the lifting platform 102, the fixed support platform 103, the needle-type detection mechanism 106, the plate-type detection mechanism 107, the photoelectric sensor 109, the moving mechanism 110, the second electric push rod 202, the first electric push rod 301, the adjustment motor 303, the micro cylinder 306, the camera 314, the electric push rod 503 and the PLC controller 4 are electrically connected, and the PLC controller 4 is electrically connected to the external computer platform. Start the second electric push rod 202, push the moving frame 204 to move downward, and drive the skeleton drawing assembly 3 to move downward together. When the second electric push rod 202 is automatically closed, the moving frame 204 moves to one side of the plate-type detection mechanism 107, and the skeleton drawing assembly 3 moves to the detection mold body 108, as shown in FIG. Figure 5As shown. Turn on the camera 314, and align the camera 314, the shooting slot 312 and one of the micro clamping claws 308. The camera 314 can capture the position of the corresponding micro clamping claw 308 and the detection boss inside the detection mold body 108 through the shooting slot 312, and transmit the captured image information to the PLC controller 4 in the form of an electrical signal for identification and comparison. When the micro clamping claw 308 is captured flush with one of the detection bosses, it means that the alignment rail 315 is aligned with the detection boss position, and the PLC controller 4 will control the first electric push rod 301 to start, push the fixed plate 302 to move to the left, and push the adjustment motor 303, the reinforcement plate 304, the micro cylinder 306 and the clamping table 305 to move to the left, pass through the detection mold body 108, and come to the clamping component 5. As the fixed plate 302 moves, the two alignment rails 315 are driven to move to the left together with the cooperation of the annular limiting groove 317 and the limiting slide bar 316, so that they penetrate into the interior of the detection mold body 108, and the two detection bosses slide into the interior of the two alignment rails 315, as shown in FIG. Figure 10 As shown. When the first electric push rod 301 is automatically closed, the clamping platform 305 moves to the clamping assembly 5. Then the micro cylinder 306 is started to push the connecting block 321 and the hexagonal ring 311 to move toward one side of the inside of the clamping platform 305, and drives one end of the multiple micro clamping claws 308 to move toward the square on one side of the inside of the clamping platform 305. Under the limit of the fixed rod 309, when one end of the micro clamping claw 308 moves toward the inside of the clamping platform 305 and closes, the other end will rotate to the outside of the clamping platform 305 and open, as shown. Figure 12In the open state, the outer surface of one side of the clamping platform 305 is the leftmost side of the entire skeleton pulling assembly 3. When the micro clamping claw 308 is misaligned with the detection boss, the PLC controller 4 will first start the adjustment motor 303, which drives the reinforcement plate 304 to rotate through the rotation of its conveying end, drives the micro cylinder 306 and the micro clamping claw 308 to rotate, and at the same time drives the alignment rail 315 to rotate on the outer surface of the fixed plate 302. At this time, the camera 314 will follow the fixed block 313 and the support ring 318 and rotate together with the alignment rail 315. When the camera 314 captures the rotation of the micro clamping claw 308 and one of the detection bosses, the adjustment motor 303 is turned off, thereby aligning the micro clamping claw 308 and the alignment rail 315 with the corresponding detection boss. Then, the first electric push rod 301 is started, and the same operation process as above is used to push the micro clamping claw 308 to the clamping assembly 5 and open the micro clamping claw 308. Through the above operation process, the positioning of the micro clamping claw 308, the alignment rail 315 and the detection boss is achieved, which facilitates the accurate insertion of the detection boss into the alignment rail 315. With the cooperation of the detection boss and the alignment rail 315, when the angle of the micro clamping claw 308 is adjusted again, the detection boss can be driven to rotate together, thereby achieving the alignment and positioning of the skeleton groove, the micro clamping claw 308 and the detection boss, which is conducive to accurately passing the skeleton from the detection mold body 108. After the optical cable skeleton passes through the needle-type detection mechanism 106, one end of the skeleton is placed on the support top block 504, and one side of the skeleton is brought into contact with the outer surface of one side of the clamping platform 305. Then, the two electric push rods 503 are activated to push the two arc clamps 505 to move relative to each other, clamping and fixing one end of the skeleton. At this time, the position of the micro-clamping claw 308 and the skeleton groove is captured by the camera 314. When the micro-clamping claw 308 is just aligned with the skeleton groove, the PLC controller 4 starts the micro-cylinder 306 again. At this time, one end of the micro-cylinder 306 pulls the connecting block 321 and the hexagonal ring 311 to move in the opposite direction, causing one end of the micro-clamping claw 308 to move in the opposite direction and open. At this time, its other end will close into the corresponding skeleton groove and tightly contact the inner wall of the skeleton groove, thereby firmly grasping one end of the skeleton. When the micro-clamping claw 308 is misaligned with the skeleton groove, the PLC controller 4 will control the adjustment motor 303 to start again, driving the micro-cylinder 306, the clamping table 305 and the opened micro-clamping claw 308 to rotate again, and driving the alignment rail 315 and the detection boss to rotate together to adjust the angle of the micro-clamping claw 308. When the micro-clamping claw 308 is aligned with the skeleton groove, the adjustment motor 303 is turned off. At this time, the micro-clamping claw 308, the skeleton groove, the alignment rail 315 and the detection boss are aligned. Then the electric push rod 503 is started again, pulling the arc clamp 505 to move in the opposite direction to release the clamping of the skeleton. Then the micro cylinder 306 is started again to drive the micro clamping claw 308 to close and clamp one end of the skeleton.Finally, the first electric push rod 301 is started again, pulling the fixed plate 302, the clamping platform 305, the alignment rail 315 and the clamped skeleton to move horizontally to the right. At this time, the alignment rail 315 is first removed from the inside of the detection mold body 108, and the detection boss slides out from the inside of the alignment rail 315. Then the clamping platform 305 is removed from the detection mold body 108, and finally the skeleton is extracted from the inside of the detection mold body 108, and the detection boss slides accurately into the skeleton groove. When the first electric push rod 301 is automatically closed, one end of the skeleton is extracted from the inside of the detection mold body 108, and the micro clamping claw 308 is removed and restored to its original position. The micro cylinder 306 is started again to release the clamping of one end of the skeleton. Then the second electric push rod 202 is started, pulling the movable frame 204 and the skeleton drawing assembly 3 to move upward and reset. Under the action of the skeleton pulling component 3, through the image acquisition of the camera 314, the adjustment motor 303 first adjusts the angle of the micro clamping claw 308, and adjusts the angle of the alignment rail 315, so that the subsequent detection boss can slide smoothly into the alignment rail 315. When the rotation angle of the micro clamping claw 308 is subsequently adjusted to align with the skeleton groove, the alignment rail 315 drives the detection boss to rotate together, so that the detection boss is aligned with the skeleton groove, thereby achieving the effect of automatic alignment and positioning, facilitating the skeleton to pass through the detection mold body 108 smoothly, without the need for staff to concentrate and observe carefully, nor to repeatedly adjust the smaller detection mold body 108, saving time and manpower, improving detection efficiency, and solving the problem that when using plate-type detection equipment to detect the skeleton groove, the staff needs to concentrate and carefully observe the relative position of the skeleton groove and the detection boss inside the detection mold, and constantly fine-tune the detection mold angle so that the skeleton groove is aligned with the detection boss inside the detection mold. The process is cumbersome, time-consuming, and affects the detection efficiency.

[0025] Example 2: Figures 1-6 and Figure 10 As shown, the detection component 1 includes a needle-type detection mechanism 106, and a plate-type detection mechanism 107 is arranged on the outer surface of one side of the needle-type detection mechanism 106. The detection component 1 also includes a base 101, a movable rail 104 is arranged on the top of the base 101, and two movable mechanisms 110 are arranged on the top of the movable rail 104. The tops of the two movable mechanisms 110 are both installed with columns 105 by bolts. The needle-type detection mechanism 106 is installed on the outer surface of one side of one of the columns 105, and the plate-type detection mechanism 107 is installed on the outer surface of one side of the other column 105. Photoelectric sensors 109 are arranged at the bottom of the outer surfaces of one side of the needle-type detection mechanism 106 and the plate-type detection mechanism 107. A detection mold body 108 is arranged inside the plate-type detection mechanism 107. Lifting platforms 102 are fixedly installed on both sides of the top of the base 101, and fixed bracket platforms 103 are arranged on the tops of the two lifting platforms 102. The bottoms of the two clamping frames 501 are both installed on the column 105 on the other side of the top of the base 101 by bolts.

[0026] In this embodiment, when in use, the optical cable skeleton is first placed on the top of the fixed bracket platform 103 on the left side in the direction from left to right, and then one end of the optical cable skeleton is passed through the needle-type detection mechanism 106, and then comes to the clamping component 5, and one end of the optical cable skeleton is clamped and fixed by the clamping component 5, and then the skeleton pulling component 3 is pushed to the plate-type detection mechanism 107 through the pulling component 2, and then the detection boss inside the detection mold body 108 is aligned with the skeleton groove of the skeleton through the skeleton pulling component 3, and one end of the skeleton is grasped, and finally the skeleton is smoothly pulled out of the detection mold body 108 through the skeleton pulling component 3, and the detection boss is accurately inserted into the skeleton groove. After the skeleton pulling assembly 3 and the lifting assembly 2 are reset, one end of the skeleton that has passed through the detection mold body 108 is pulled, and the skeleton is continued to be pulled to the top of the fixed support platform 103 on the right side. Finally, it is connected to the external power equipment to provide power for the subsequent movement of the skeleton. The optical cable skeleton is limited by the fixed support platforms 103 on both sides to facilitate the subsequent balanced movement of the skeleton and better detection of the skeleton groove. When the optical cable skeleton is driven by the external power equipment to move, the microscopic defects on the inner wall of the skeleton groove are first detected by the needle-type detection mechanism 106, and then the macroscopic features of the skeleton groove are detected by the plate-type detection mechanism 107. Both the needle-type detection mechanism 106 and the plate-type detection mechanism 107 are currently mature technologies. The needle-type detection mechanism 106 typically includes a needle-type scanning laser radar probe, a sensor, a drive device, a data acquisition and processing module, etc. Multiple needle-type scanning laser radar probes scan the skeleton grooves to obtain the contour information of the skeleton groove inner wall. The drive device is used to control the movement of the needle-type probes, enabling them to scan and detect the skeleton grooves according to a predetermined path and method. The data acquisition and processing system is responsible for collecting sensor data, analyzing and processing it, and comparing it with preset standard data or models to determine whether the skeleton groove inner wall has defects such as unevenness, cracks, and depressions. The plate-type detection mechanism 107 typically includes a detection mold body 108, a transmission mechanism, an encoder, and a control module. When an external power device drives the optical cable skeleton to translate through the detection mold body 108, the interaction between the skeleton groove and the detection boss inside the detection mold body 108 drives the detection mold body 108 to rotate. The rotational motion of the detection mold body 108 is transmitted to the encoder through the transmission mechanism, and the encoder converts the rotational motion into an electrical signal and transmits it to the control unit. The control unit converts the electrical signal sent by the encoder into relevant parameters such as pitch value, and judges whether the skeleton slot is qualified based on the preset pitch value range and other standard parameters such as shape and size, thereby detecting whether the skeleton slot has defects such as inaccurate pitch, deformation, incomplete structure, etc.The needle type detection mechanism 106 and the plate type detection mechanism 107 are combined in the detection assembly 1, the needle type detection mechanism can accurately measure and detect the local details of the skeleton groove, and the plate type detection mechanism can grasp the shape, size and pitch and other parameters of the skeleton groove as a whole, the combination of the two can complement each other, more comprehensively and accurately detect various defects in the skeleton groove, realize the comprehensive detection of multiple parameters of the skeleton groove, more accurately evaluate the quality and performance of the skeleton groove, and improve the detection efficiency and accuracy.

[0027] The method of use and working principle of the present invention are as follows: start the second electric push rod 202, push the movable frame 204 downward, so that the skeleton drawing assembly 3 moves to the detection mold body 108. Turn on the camera 314, take a picture of the position of the micro clamping claw 308 and the detection boss inside the detection mold body 108, and transmit it to the PLC controller 4 for identification and comparison. When the micro clamping claw 308 is photographed and flush with the detection boss, the PLC controller 4 will control the first electric push rod 301 to start, push the fixed plate 302 to move to the left, drive the clamping table 305 to move, pass through the detection mold body 108, and reach the clamping assembly 5. At the same time, the alignment rail 315 penetrates into the detection mold body 108, and the two detection bosses slide into the two alignment rails 315. When the first electric push rod 301 automatically closes, the micro-cylinder 306 is activated, pushing the connecting block 321 and the hexagonal ring 311 to move. Under the limit of the fixed rod 309, when one end of the micro-clamping claw 308 closes, its other end rotates outward to open. When the micro-clamping claw 308 is photographed to be misaligned with the detection boss, the PLC controller 4 will first start the adjustment motor 303, driving the reinforcement plate 304 and the micro-clamping claw 308 to rotate, while also driving the alignment rail 315 and the camera 314 to rotate together. When the camera 314 captures the rotated micro-clamping claw 308 aligned with one of the detection bosses, the adjustment motor 303 is turned off. Then, the first electric push rod 301 is activated, and the operation process is the same as described above. The optical cable skeleton is passed through the needle-type detection mechanism 106 from the fixed support platform 103 on the left side, and then the skeleton is placed on the support top block 504, so that one side of the skeleton contacts the outer surface of one side of the clamping platform 305. The two electric push rods 503 are activated, pushing the two arc-shaped clamps 505 to clamp and secure one end of the skeleton. The camera 314 captures the position of the micro-clamping claws 308 and the skeleton slot. When the micro-clamping claws 308 are aligned with the skeleton slot, the PLC controller 4 activates the micro-cylinder 306, driving the micro-clamping claws 308 to close inside the corresponding skeleton slot, firmly grasping one end of the skeleton. If the micro-clamping claws 308 are misaligned with the skeleton slot, the PLC controller 4 controls the adjustment motor 303 to start again, driving the micro-clamping claws 308 to rotate again. The alignment rail 315 drives the detection boss to rotate together, adjusting the angle of the micro-clamping claws 308. When the micro-clamping claws 308 are aligned with the skeleton slot, the adjustment motor 303 is turned off, and the micro-clamping claws 308, the skeleton slot, the alignment rail 315, and the detection boss are aligned. The electric push rods 503 are then activated again, pulling the arc-shaped clamps 505 in the opposite direction, loosening the clamping force on the skeleton. Then the micro cylinder 306 is started to drive the micro clamping claw 308 to clamp one end of the skeleton. Finally, the first electric push rod 301 is started again to pull the skeleton to move horizontally to the right side and pass through the detection mold body 108. At the same time, the detection boss slides accurately into the skeleton groove.When the first electric push rod 301 is automatically closed, the micro cylinder 306 is started again to release the clamping of one end of the skeleton, and then the second electric push rod 202 is started, pulling the movable frame 204 and the skeleton pulling assembly 3 to move upward and reset. Then, pull one end of the skeleton that passes through the detection mold body 108, and continue to pull the skeleton so that it is placed on the top of the fixed support platform 103 on the right, and finally connected to the external power equipment. In the process of moving the optical cable skeleton by the external power equipment, it first passes through the needle-type detection mechanism 106. The needle-type detection mechanism 106 usually includes a needle-type scanning laser radar probe, a sensor, a drive device, a data acquisition and processing module, etc. The needle-type scanning laser radar probe scans the skeleton groove, obtains the contour information of the inner wall of the skeleton groove, and determines whether there are defects such as unevenness, cracks, and depressions on the inner wall of the skeleton groove. Then it passes through the plate-type detection mechanism 107, which usually includes a detection mold body 108, a transmission mechanism, an encoder and a control module. When the optical cable skeleton translates through the detection mold body 108, the skeleton groove and the detection boss inside the detection mold body 108 cooperate with each other, which will drive the detection mold body 108 to rotate, generate corresponding pitch values ​​and other related parameters, and detect whether there are defects such as inaccurate pitch, deformation, and incomplete structure in the skeleton groove.

[0028] Among them, the lifting platform 102, the fixed support platform 103, the needle-type detection mechanism 106, the plate-type detection mechanism 107, the photoelectric sensor 109, the moving mechanism 110, the second electric push rod 202, the first electric push rod 301, the adjustment motor 303, the micro cylinder 306, the camera 314, the electric push rod 503 and the PLC controller 4 are all existing technologies, and their components and usage principles are all public technologies, so no excessive explanation will be given here.
