Description

Technical Field

[0001] This invention relates to the field of optical cable skeleton groove material testing technology, specifically to an online detection device and method for defects inside the skeleton groove of a skeleton-type optical cable. Background Technology

[0002] Skeleton-type optical cables are suitable for relay networks. Their structure uses a skeleton and central reinforcement as support units to ensure the cable's mechanical properties and temperature characteristics. The skeleton slot is a specific structure located on the skeleton of the cable, its function being to accommodate information carriers such as fiber ribbons, providing protection and positioning for the optical fibers. The shape and size of the skeleton slot directly affect the placement and protection effect of the optical fibers. Online detection of defects within the skeleton slot allows for early adjustment of process parameters or corresponding measures during production.

[0003] In existing online inspections of skeleton-type optical cable skeleton slots, plate-type inspection equipment is used to check whether the pitch of the skeleton slot is accurate. The skeleton needs to be passed through the central through hole of the inspection mold. When the skeleton moves through the inspection mold, the inspection mold will be driven to rotate due to the interaction between the skeleton slot and the inspection boss on the inspection mold, thereby detecting the pitch of the skeleton slot.

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

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

[0018] A method for using an online defect detection device for the skeleton groove of a skeleton-type optical cable includes the following steps:

[0019] S1. The camera captures the position images of the miniature clamping claw and the detection boss. When the miniature clamping claw and the detection boss are misaligned, the PLC controller will first start the adjustment motor to drive the reinforcing plate, the miniature clamping claw and the alignment rail to rotate. When the miniature clamping claw is aligned with one of the detection bosses, the adjustment motor will be turned off.

[0020] S2. Start the first electric actuator to push the fixed plate to the left, so that the clamping platform 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.

[0021] S3. After the optical cable skeleton passes through the needle-type detection mechanism, the two electric push rods are activated to push the two arc-shaped clamps to move relative to each other, clamping and fixing one end of the skeleton.

[0022] S4. When the camera captures the micro clamping claw being misaligned with the skeleton groove, start the adjustment motor to drive the micro clamping claw, alignment rail and detection boss to rotate together, so that the micro clamping claw is aligned with the skeleton groove. Then start the micro cylinder again to drive the micro cylinder to close and firmly grasp one end of the skeleton.

[0023] S5. Restart the electric push rod to release the clamp on the skeleton, then restart the first electric push rod to pull the skeleton out from inside the detection mold body. At the same time, the detection boss slides precisely into the skeleton groove. Then, the micro clamping claw releases the clamp on the skeleton, and the second electric push rod drives the skeleton pulling assembly to move upward and reset.

[0024] S6. During the process of moving the optical cable skeleton by external power equipment, it first passes through the needle detection mechanism. The needle scanning laser radar probe scans the skeleton groove to obtain the contour information of the inner wall of the skeleton groove and detects the micro-defects in the inner wall of the skeleton groove.

[0025] S7. Then, through the plate-type inspection mechanism, the skeleton groove and the inspection boss inside the inspection mold body cooperate with each other, which will drive the inspection mold body to rotate, generate corresponding pitch values ​​and other related parameters, and detect whether there are defects such as inaccurate pitch, deformation, or incomplete structure in the skeleton groove.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. In use, the first electric actuator is activated to move the fixing plate to the left, allowing the clamping platform and alignment rail to pass through the detection mold body. The micro cylinder is then activated to open the micro clamping jaws. When the camera detects that the micro clamping jaws are misaligned with the skeleton groove, the adjusting motor is activated to rotate the micro clamping jaws, alignment rail, and detection boss together, aligning the micro clamping jaws with the skeleton groove. The micro cylinder is then activated again to close, firmly gripping one end of the skeleton. The first electric actuator is activated again to pull the skeleton out of the detection mold body, while the detection boss precisely slides into the skeleton groove. The skeleton pulling assembly achieves automatic alignment and positioning, facilitating the smooth passage of the skeleton through the detection mold body. This eliminates the need for operators to concentrate on careful observation or repeatedly adjust the smaller detection mold body, saving time and manpower and improving detection efficiency.

[0028] 2. When using this invention, the position images of the miniature clamping claw and the detection boss are captured by a camera. When the miniature clamping claw and the detection boss are misaligned, the PLC controller will first start the adjustment motor to drive the reinforcing plate, the miniature clamping claw, and the alignment rail to rotate. When the miniature clamping claw is aligned with one of the detection bosses, the adjustment motor is turned off, thus realizing the positioning of the miniature clamping claw, the alignment rail, and the detection boss. With the cooperation of the detection boss and the alignment rail, it is convenient to realize the subsequent alignment and positioning of the skeleton groove, the miniature clamping claw, and the detection boss.

[0029] 3. In use, during the movement of the optical cable skeleton, the needle-type detection mechanism scans the skeleton groove using a needle-type scanning laser radar probe to obtain the contour information of the inner wall of the skeleton groove, detecting microscopic defects in the inner wall of the skeleton groove. Then, the plate-type detection mechanism drives the detection mold body to rotate, generating corresponding pitch values ​​and other related parameters, detecting whether there are defects such as inaccurate pitch, deformation, or structural incompleteness in the skeleton groove. The detection component combines a needle-type detection mechanism and a plate-type detection mechanism. The needle-type detection can accurately measure and detect local details of the skeleton groove, while the plate-type detection can grasp the overall shape, size, pitch, and other parameters of the skeleton groove. The combination of the two can complement each other, more comprehensively and accurately detecting various defects in the skeleton groove, achieving comprehensive detection of multiple parameters of the skeleton groove, more accurately evaluating the quality and performance of the skeleton groove, and improving detection efficiency and accuracy.

The other end of the first electric push rod 301 is fixedly installed inside the movable frame 204. On the opposite sides of the two aligned rails 315, I-shaped sliders 320 are fixedly installed. The outer surfaces of the two I-shaped sliders 320 are movably embedded inside the two limiting grooves 205. The clamping assembly 5 includes a clamping seat 502. Electric push rods 503 are fixedly installed on both sides inside the clamping seat 502. An arc-shaped clamp 505 is fixedly installed at one end of each of the two electric push rods 503. A support top block 504 is fixedly installed on the bottom surface inside the clamping seat 502. Clamping frames 501 are fixedly installed on both sides of the bottom of the clamping seat 502. The top end of the second electric push rod 202 is fixedly installed at the center of the top surface inside the mounting frame 201. Spring telescopic rods 203 are fixedly installed on both sides of the top surface inside 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.

[0046] In this embodiment, during use, the lifting platform 102, fixed support platform 103, needle-type detection mechanism 106, plate-type detection mechanism 107, photoelectric sensor 109, moving mechanism 110, second electric push rod 202, first electric push rod 301, adjusting motor 303, miniature cylinder 306, camera 314, electric push rod 503, and PLC controller 4 are electrically connected. The PLC controller 4 is electrically connected to an external computer platform. Activating the second electric push rod 202 pushes the moving frame 204 downwards, causing the skeleton pull-out assembly 3 to move downwards as well. When the second electric push rod 202 automatically closes, the moving frame 204 moves to one side of the plate-type detection mechanism 107, and the skeleton pull-out assembly 3 moves to the detection mold body 108. Figure 5As shown. Camera 314 is turned on, and the camera 314, the shooting slot 312, and one of the miniature clamping claws 308 are aligned. The camera 314 can capture the position of the corresponding miniature 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 for recognition and comparison via electrical signals. When the miniature clamping claw 308 is aligned with one of the detection bosses, it means that the alignment rail 315 is aligned with the detection boss. The PLC controller 4 will then control the first electric push rod 301 to start, pushing the fixing plate 302 to move to the left, and pushing the adjusting motor 303, the reinforcing plate 304, the miniature cylinder 306, and the clamping table 305 to move to the left, passing through the detection mold body 108, and arriving at the clamping assembly 5. As the fixed plate 302 moves, it is driven by the cooperation of the annular limiting groove 317 and the limiting slide rod 316 to move the two alignment rails 315 to the left, so that they pass into the interior of the detection mold body 108, and two of the detection bosses slide into the interior of the two alignment rails 315, as shown. Figure 10 As shown. When the first electric actuator 301 automatically closes, the clamping table 305 moves to the clamping assembly 5. Then, the micro cylinder 306 is activated, pushing the connecting block 321 and the hexagonal ring 311 to move towards one side of the clamping table 305, and causing one end of each of the multiple micro clamping claws 308 to move towards the square side of the clamping table 305. Under the limit of the fixing rod 309, when one end of the micro clamping claw 308 moves towards the inside of the clamping table 305 and closes, its other end will rotate outward from the clamping table 305 and open, as shown. Figure 12In the open state, one outer surface of the clamping table 305 is the leftmost side of the entire skeleton pull-out assembly 3. When the micro clamping claw 308 is captured as misaligned with the detection boss, the PLC controller 4 first starts the adjusting motor 303, which rotates the reinforcing plate 304 through the rotation of its conveying end, causing the micro cylinder 306 and the micro clamping claw 308 to rotate. At the same time, the alignment rail 315 rotates on the outer surface of the fixing plate 302. At this time, the camera 314 will rotate along with the fixing block 313 and the support ring 318 and the alignment rail 315. When the camera 314 captures the micro clamping claw 308 after rotation aligned with one of the detection bosses, the adjusting motor 303 is turned off, so that the micro clamping claw 308, the alignment rail 315 and the corresponding detection boss are aligned. Then the first electric push rod 301 is started, and the same operation process as above is performed 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 miniature clamping claw 308, the alignment rail 315, and the detection boss is achieved, facilitating the precise insertion of the detection boss into the alignment rail 315. With the cooperation of the detection boss and the alignment rail 315, it is convenient to rotate the detection boss together when the angle of the miniature clamping claw 308 is adjusted later, thereby achieving the alignment and positioning of the skeleton groove, the miniature clamping claw 308, and the detection boss. This is beneficial for accurately passing the skeleton through 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 contacts the outer surface of one side of the clamping table 305. Then, the two electric push rods 503 are activated, pushing the two arc-shaped clamps 505 to move relative to each other, clamping and fixing one end of the skeleton. At this time, the camera 314 captures the position of the miniature clamping claw 308 and the skeleton groove. When the miniature clamping claw 308 is aligned with the skeleton groove, the PLC controller 4 restarts the miniature cylinder 306. At this time, one end of the miniature cylinder 306 pulls the connecting block 321 and the hexagonal ring 311 to move in the opposite direction, causing one end of the miniature 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 make tight contact with the inner wall of the skeleton groove, thus firmly gripping one end of the skeleton. When the camera captures that the position of the miniature clamping claw 308 is misaligned with the skeleton groove, the PLC controller 4 will control the adjusting motor 303 to start again, driving the miniature cylinder 306, the clamping table 305 and the opened miniature clamping claw 308 to rotate again, and driving the alignment rail 315 and the detection boss to rotate together, adjusting the angle of the miniature clamping claw 308. When the miniature clamping claw 308 is aligned with the skeleton groove, the adjusting motor 303 is turned off. At this time, the miniature clamping claw 308, the skeleton groove, the alignment rail 315 and the detection boss are aligned. Next, the electric push rod 503 is activated again, pulling the arc-shaped clamp 505 to move in the opposite direction and release the clamp on the skeleton. Then, the micro cylinder 306 is activated again, driving the micro clamping claw 308 to close and clamp one end of the skeleton.Finally, the first electric actuator 301 is activated again, pulling the fixing plate 302, clamping platform 305, alignment rail 315, and the clamped skeleton to move horizontally to the right. At this time, the alignment rail 315 first moves out of the detection mold body 108, and the detection boss slides out of the alignment rail 315. Then, the clamping platform 305 moves out of the detection mold body 108, and finally, the skeleton is pulled out of the detection mold body 108, while the detection boss slides precisely into the skeleton groove. When the first electric actuator 301 automatically closes, one end of the skeleton is pulled out of the detection mold body 108, and the miniature clamping claw 308 moves out and returns to its original position. The miniature cylinder 306 is activated again to release the clamp on one end of the skeleton. Then, the second electric actuator 202 is activated, pulling the moving frame 204 and the skeleton pulling assembly 3 upward to reset. Under the action of the skeleton pulling assembly 3, the image acquisition by the camera 314, in conjunction with the adjustment motor 303, first adjusts the angle of the miniature clamping claw 308 and then adjusts the angle of the alignment rail 315, so that the subsequent detection boss can smoothly slide into the alignment rail 315. When the subsequent adjustment of the miniature clamping claw 308 rotates 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. This facilitates the skeleton to pass smoothly through the detection mold body 108 without the need for the staff to concentrate on careful observation or repeatedly adjust the small detection mold body 108, saving time and manpower, improving detection efficiency. This solves the problem that when using plate-type detection equipment to detect the inside of the skeleton groove, the staff needs to concentrate on carefully observing the relative position of the skeleton groove and the detection boss inside the detection mold, and constantly fine-tuning the angle of the detection mold to make the skeleton groove align with the detection boss inside the detection mold. This process is cumbersome, time-consuming, and affects detection efficiency.

[0047] Example 2: Figures 1-6 and Figure 10 As shown, the detection component 1 includes a needle-type detection mechanism 106, a plate-type detection mechanism 107 is provided on one outer surface of the needle-type detection mechanism 106, and the detection component 1 also includes a base 101. A moving rail 104 is provided on the top of the base 101, and two moving mechanisms 110 are provided on the top of the moving rail 104. A column 105 is bolted to the top of each of the two moving mechanisms 110. The needle-type detection mechanism 106 is installed on one outer surface of one column 105, and the plate-type detection mechanism 107 is installed on one outer surface of the other column 105. A photoelectric sensor 109 is provided at the bottom of one outer surface of both the needle-type detection mechanism 106 and the plate-type detection mechanism 107. A detection mold body 108 is provided inside the plate-type detection mechanism 107. Lifting platforms 102 are fixedly installed on both sides of the top of the base 101. A fixed support platform 103 is provided on the top of each of the two lifting platforms 102. The bottom of the two clamping frames 501 is bolted to the other column 105 on the top of the base 101.

[0048] In this embodiment, during use, the optical cable skeleton is first placed on the top of the fixed support platform 103 on the left side in a left-to-right direction. Then, one end of the optical cable skeleton is passed through the needle detection mechanism 106 and then to the clamping component 5. The clamping component 5 clamps and fixes one end of the optical cable skeleton. Then, the skeleton pulling component 3 is pushed to the plate detection mechanism 107 by the lifting component 2. Then, the detection boss inside the detection mold body 108 is aligned with the skeleton groove of the skeleton by the skeleton pulling component 3, and one end of the skeleton is grasped. Finally, the skeleton is smoothly pulled out from the detection mold body 108 by the skeleton pulling component 3, so that the detection boss is accurately inserted into the skeleton groove. After the skeleton pulling assembly 3 and lifting assembly 2 are reset, one end of the skeleton protruding from the inspection mold body 108 is pulled, and the skeleton is continued to be pulled until it is placed on top of the fixed support platform 103 on the right. Finally, it is connected to the external power equipment to provide power for the subsequent movement of the skeleton. The fixed support platforms 103 on both sides limit the movement of the optical cable skeleton, which facilitates the balanced movement of the skeleton and better inspection of the skeleton groove. During the movement of the optical cable skeleton driven by the external power equipment, the microscopic defects of the inner wall of the skeleton groove are first detected by the needle-type inspection mechanism 106, and then the macroscopic features of the skeleton groove are detected by the plate-type inspection mechanism 107. Both the needle-type inspection mechanism 106 and the plate-type inspection mechanism 107 are existing mature technologies. The needle-type inspection mechanism 106 typically includes needle-type scanning lidar probes, sensors, a drive unit, and a data acquisition and processing module. Multiple needle-type scanning lidar probes scan the skeleton groove to obtain the contour information of the inner wall of the skeleton groove. The drive unit controls the movement of the needle probes, enabling them to scan and inspect the skeleton groove according to a predetermined path and method. The data acquisition and processing system is responsible for collecting, analyzing, and processing the sensor data. By comparing it with preset standard data or models, it determines whether there are defects such as unevenness, cracks, or dents on the inner wall of the skeleton groove. The plate-type inspection mechanism 107 typically includes an inspection mold body 108, a transmission mechanism, an encoder, and a control module. When an external power device drives the optical cable skeleton to translate past the inspection mold body 108, the skeleton groove and the inspection boss inside the inspection mold body 108 cooperate to drive the inspection mold body 108 to rotate. The rotational motion of the inspection mold body 108 is transmitted to the encoder through the transmission mechanism, and the encoder converts the rotational motion into an electrical signal and sends 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 groove is qualified according to the preset pitch value range and other standard parameters such as shape and size, thereby detecting whether there are defects such as inaccurate pitch, deformation, or incomplete structure in the skeleton groove.The detection component 1 combines a needle-type detection mechanism 106 and a plate-type detection mechanism 107. The needle-type detection can accurately measure and detect the local details of the skeleton groove, while the plate-type detection can grasp the overall shape, size, pitch and other parameters of the skeleton groove. 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.

[0049] The method of use and working principle of this invention are as follows: The second electric actuator 202 is activated, pushing the movable frame 204 downwards, causing the skeleton pull-out assembly 3 to move to the detection mold body 108. The camera 314 is activated to capture images of the positions of the miniature clamping claw 308 and the detection boss inside the detection mold body 108, and this image is sent to the PLC controller 4 for identification and comparison. When the image shows that the miniature clamping claw 308 is flush with the detection boss, the PLC controller 4 controls the first electric actuator 301 to activate, pushing the fixed plate 302 to move to the left, causing the clamping platform 305 to move through the detection mold body 108 and arrive at the clamping assembly 5. Simultaneously, the alignment rails 315 are inserted into the detection mold body 108, with two detection bosses sliding into the two alignment rails 315. When the first electric actuator 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, the other end will rotate outward to open. When the micro clamping claw 308 is captured as misaligned with the detection boss, the PLC controller 4 will first activate the adjusting motor 303, driving the reinforcing plate 304 and the micro clamping claw 308 to rotate, and simultaneously 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 adjusting motor 303 is turned off. Then the first electric actuator 301 is activated, and the same operation process is performed. The optical cable frame is passed through the needle detection mechanism 106 from the fixed support platform 103 on the left, and then the frame is placed on the support top block 504, so that one side of the frame contacts the outer surface of one side of the clamping platform 305. Two electric actuators 503 are activated, pushing two arc-shaped clamps 505 to hold and fix one end of the skeleton. Camera 314 captures the position of the miniature clamping claw 308 relative to the skeleton groove. When the miniature clamping claw 308 aligns with the skeleton groove, PLC controller 4 activates miniature cylinder 306, driving the miniature clamping claw 308 to close into the corresponding skeleton groove, firmly gripping one end of the skeleton. When the camera captures a misalignment between the miniature clamping claw 308 and the skeleton groove, PLC controller 4 controls adjustment motor 303 to restart, driving the miniature clamping claw 308 to rotate again. This rotates the detection boss via alignment rail 315, adjusting the angle of the miniature clamping claw 308. When the miniature clamping claw 308 aligns with the skeleton groove, adjustment motor 303 is turned off. At this point, the miniature clamping claw 308, skeleton groove, alignment rail 315, and detection boss are aligned. Then, electric actuators 503 are activated again, pulling the arc-shaped clamps 505 in the opposite direction, releasing the skeleton. Then, the micro cylinder 306 is activated, driving the micro clamping claw 308 to clamp one end of the skeleton. Finally, the first electric actuator 301 is activated again, pulling the skeleton to move horizontally to the right, passing through the detection mold body 108, while the detection boss precisely slides into the skeleton groove.When the first electric actuator 301 automatically closes, the micro cylinder 306 is activated again to release the clamp on one end of the skeleton. Then, the second electric actuator 202 is activated, pulling the moving frame 204 and the skeleton pulling assembly 3 upward to reset. Then, the skeleton end protruding from the detection mold body 108 is pulled and the skeleton is continued to be pulled, placing it on top of the fixed support platform 103 on the right side, and finally connected to the external power equipment. During the movement of the optical cable skeleton driven by the external power equipment, it first passes through the needle detection mechanism 106. The needle detection mechanism 106 typically includes a needle scanning laser radar probe, sensor, drive device, data acquisition and processing module, etc. The needle scanning laser radar probe scans the skeleton groove to obtain the contour information of the inner wall of the skeleton groove and determine whether there are defects such as unevenness, cracks, and dents in the inner wall of the skeleton groove. Next, the optical cable skeleton passes through the plate-type inspection mechanism 107. The plate-type inspection mechanism 107 typically includes an inspection mold body 108, a transmission mechanism, an encoder, and a control module. When the optical cable skeleton moves through the inspection mold body 108, the skeleton groove and the inspection boss inside the inspection mold body 108 cooperate with each other, which will drive the inspection mold body 108 to rotate, generating corresponding pitch values ​​and other related parameters, and detecting whether there are defects such as inaccurate pitch, deformation, or incomplete structure in the skeleton groove.

[0050] Among them, the lifting platform 102, the fixed support platform 103, the needle detection mechanism 106, the plate detection mechanism 107, the photoelectric sensor 109, the moving mechanism 110, the second electric push rod 202, the first electric push rod 301, the adjusting motor 303, the miniature cylinder 306, the camera 314, the electric push rod 503 and the PLC controller 4 are all existing technologies, and their components and operating principles are all publicly available technologies, which will not be explained in detail here.
