Description

Technical Field

[0001] This invention relates to the field of visual defect detection devices, specifically to an online visual defect detection device for fishing line winding. Background Technology

[0002] In continuous production of fishing line winding, the fishing line travels at high speed and is wound into a coil. The fishing line itself is thin and has a limited load-bearing capacity. During production, it is susceptible to breakage due to multiple factors, including inherent defects in raw materials, continuous equipment vibration, frequent fluctuations in winding tension, and friction and wear of guide components. If a break occurs and is not identified and addressed promptly, the broken thread can easily become entangled in guide components, causing blockages and unplanned production line shutdowns. Furthermore, the accumulation of broken and loose threads can interfere with conventional optical detection paths, increasing the risk of misjudgments. Therefore, online visual defect detection equipment is commonly used in the fishing line winding process to capture the fishing line's operating status in real time and predict or identify breakage faults using visual monitoring methods, ensuring orderly production.

[0003] In current fishing line winding operations, factors such as tension fluctuations and transmission disturbances in the winding and unwinding mechanisms can easily induce irregular radial shaking of the fishing line. To reduce the detection deviation caused by fishing line shaking, existing online visual defect detection equipment generally uses ceramic guides to limit and regulate the fishing line, thereby suppressing line sway. However, the above still has the following shortcomings under actual high-speed operating conditions: Firstly, the fishing line constantly vibrates irregularly in the up-down and left-right directions during high-speed travel, causing it to rub against the inner wall of the ceramic guide and accumulate static electricity. This static charge can firmly attract impurities such as dust and fiber clumps from the workshop. These deposits enter the infrared and visual detection areas along with the fishing line. The deposited impurities cause abnormal fluctuations in the infrared light transmission intensity, and the outline of the impurities in the imaging image is highly similar to the cracks and surface scratches on the fishing line. The detection system has difficulty accurately distinguishing between foreign deposits and defects in the fishing line itself, resulting in frequent false triggering and false alarms of the equipment. This leads to an increase in unnecessary shutdowns of the production line and a decrease in overall production efficiency. Secondly, fishing lines carrying static electricity are prone to instantaneous discharge due to air breakdown in narrow gaps. The clumps adsorbed on the surface of the fishing line will form a pointed structure, which will also induce instantaneous discharge at the pointed end. The instantaneous discharge of static electricity will generate electromagnetic pulses, which will interfere with the weak photoelectric signals of the transmitted infrared receiver, causing irregular baseline drift and weakening the infrared system's ability to capture minute defects such as instantaneous cracks and internal delamination in the fishing line. At the same time, static electricity will disturb the signal transmission of industrial cameras, resulting in increased image noise, image stripe distortion, reduced visual recognition accuracy, and a significant increase in the probability of missing minute defects. Summary of the Invention

The execution structure is located below the electrostatic collection structure; The detection structure is mounted on the circuit board. The energy storage unit is mounted on the circuit board; The execution structure is located in the execution chamber. The electrostatic collection structure collects the static electricity generated by the friction between the fishing line and the C-shaped ceramic part, converts it into electrical energy and stores it in the energy storage unit. The energy storage unit provides driving energy for the execution structure, which drives the C-shaped ceramic part to complete the opening and closing action of the ceramic guide eye.

[0007] Preferably, the energy storage unit includes: Supercapacitors; The rectifier circuit is electrically connected to the input terminal of the supercapacitor; The electrostatic discharge protection circuit is electrically connected between the rectifier circuit and the collector.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides an online visual defect detection device for fishing line winding, which has the following beneficial effects: 1. This online visual defect detection device for fishing line winding collects and dissipates static electricity generated by friction through an electrostatic collection structure. The stored electrical energy is used as the driving energy for the actuators, eliminating the need for mains power or compressed air. Long-term industrial use can continuously reduce operating costs, demonstrating significant energy-saving advantages. It does not rely on external power sources such as external motors or pneumatic power supplies. By collecting and dissipating static electricity generated by friction in real time, it prevents the continuous accumulation of charge on the fishing line surface, eliminating the fundamental conditions for electrostatic adsorption of dust and fiber debris. This effectively improves the cleanliness of the fishing line surface, reduces detection errors caused by contaminants, and further enhances... High accuracy in detecting broken wires and defects transforms harmful static electricity, which can easily cause dust accumulation, discharge interference, and baseline drift, into storable and usable electrical energy, enabling the recovery and reuse of static electricity. At the same time, the flexible dielectric film and collector do not directly contact the fishing line throughout the process, preventing scratches on the fishing line surface and the formation of false defects. This ensures that the transmission infrared detection module and the high-speed vision detection module acquire real and effective images and optical signals, maintaining detection accuracy. The entire structure has no continuous mechanical friction loss, effectively extending the service life of the flexible dielectric film and collector, reducing the frequency of later inspections and replacements, and reducing daily maintenance workload.

[0016] 2. This online visual defect detection device for fishing line winding opens the C-shaped ceramic parts outward through the actuator structure, making the line routing area radially open. When workers perform line breakage replacement or clearing stuck lines, there is no need to thread long lines along the fishing line axis or pull the lines forcefully. Fishing lines can be loaded and unloaded directly from the side, simplifying the cleaning process, effectively shortening equipment downtime, and ensuring the continuous and stable operation of the fishing line winding production line. When the energy storage unit has insufficient power and cannot rely on the push-pull electromagnet to drive the mechanism, workers can manually pull the lever. The lever drives the rack and pinion to complete the displacement transmission. Relying on manual mechanical driving force, the transmission mechanism is driven to swing and open / close the C-shaped ceramic parts on both sides, realizing the opening and closing of the ceramic guide eyes. Even if the electric drive fails due to insufficient power, the line routing area can still be opened laterally, making it convenient for personnel to clean broken lines and load and unload fishing lines. This avoids problems such as the mechanism being unable to open or the equipment being locked and unable to be repaired due to insufficient energy storage, improving the fault tolerance of the device and ensuring the smooth operation of on-site maintenance work under fault conditions.

[0017] 3. This online visual defect detection device for fishing line winding uses paired C-shaped ceramic parts that interlock to form a channel for the fishing line. The C-shaped ceramic parts have an arc greater than 180°. After being gathered, the arc segments overlap and wrap around each other, resulting in high concentricity of the formed circular holes and a smooth, continuous inner wall. This provides better radial constraint on the fishing line than ordinary semi-circular splicing structures, effectively suppressing fishing line vibration and deviation, reducing the reciprocating friction intensity between the fishing line and the ceramic. Furthermore, the overlapping arc segments in the gathered state eliminate the problem of the fishing line getting stuck in the gap and locking up, reducing the problems of line breakage and ceramic chipping caused by forced pulling, and lowering the wear and tear on the equipment and fishing line.

[0018] 4. This online visual defect detection device for fishing line winding, when the drive rack moves, forces the locking pin to disengage from the current slot and slide into the movable slot. The locking pin continues to slide along the inside of the movable slot until it aligns with another slot. The torsion spring releases the stored torque, driving the deflector to rotate and push the locking pin into the slot, thus locking the drive rack position. This stably maintains the open or closed state of the C-shaped ceramic part. There is no need for the electromagnet to be continuously energized to maintain the thrust; the electromagnet only needs to output power momentarily to complete the position switching. After reaching the position, the mechanical locking structure maintains the position, significantly reducing power consumption and the power supply load of the energy storage unit. At the same time, the locking and positioning are reliable and can resist the position deviation caused by equipment vibration and working condition impact, effectively preventing the C-shaped ceramic part from accidentally rebounding or swinging, ensuring the stability of the guide structure and improving the reliability of the device operation.

[0019] 5. This online visual defect detection device for fishing line winding is linked with the ultrasonic line breakage detection and execution structure. Once a line breakage is detected, the main control module immediately outputs a linkage control signal to start the execution structure, causing the C-shaped ceramic part to swing outward and open laterally, making it easier for staff to quickly clean up broken wires and deal with line jamming faults.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] This embodiment provides an online visual defect detection device for fishing line winding, which has the following technical features.

[0038] Please see Figure 1-6 and Figure 12 A complete set of online visual defect detection device for fishing line winding includes a support structure 1, a base 12 consisting of a central receiving chamber and an execution chamber, a circuit board 3 is provided in the central receiving chamber, a bracket 13 is provided on the top of the base 12, and a support base plate 11 is provided at the bottom. The electrostatic collection structure 2 has two pairs of C-shaped ceramic parts 21, which together form a ceramic guide eye for the fishing line to pass through. The execution structure 6 is located below the electrostatic collection structure 2; The detection structure is mounted on circuit board 3; The energy storage unit is mounted on circuit board 3; The execution structure 6 is located in the execution chamber. The electrostatic collection structure 2 collects the static electricity generated by the friction between the fishing line and the C-shaped ceramic part 21, converts it into electrical energy and stores it in the energy storage unit. The energy storage unit provides driving energy for the execution structure 6, and the execution structure 6 drives the C-shaped ceramic part 21 to complete the opening and closing action of the ceramic guide eye.

[0039] More specifically, the support base plate 11 is provided with a support frame on the top, and the circuit board 3 is detachably mounted on the top of the support frame to support the circuit board 3.

[0040] In this embodiment, the paired C-shaped ceramic parts 21 surround each other to form a channel for the fishing line. The arc of the C-shaped ceramic parts 21 is greater than 180°. After being gathered, the arc segments overlap and wrap around each other. The concentricity of the formed circular hole is high and the inner wall is continuous and smooth. The radial constraint ability on the fishing line is better than that of ordinary semi-circular splicing structure. It can effectively suppress the shaking and deviation of the fishing line, reduce the reciprocating friction intensity between the fishing line and the ceramic, and the arc segments overlap in the gathered state without through gaps. Structurally, it eliminates the problem of the fishing line getting stuck in the gap and locking up, reduces the problem of line breakage and ceramic chipping damage caused by forced pulling, and reduces equipment and fishing line wear.

[0041] It should be noted that the circuit board 3 is equipped with a communication module. The fishing line detection signals collected by the infrared transmission detection module 4 and the ultrasonic sensor 5 are transmitted to the circuit board 3 for processing. The communication module can remotely upload the detection information such as real-time monitoring data, line breakage fault records, and equipment operating status to the cloud platform, realizing cloud storage of data and remote online supervision. Managers can use the cloud platform to view the monitoring data of each workstation on the production line in real time, which facilitates production data analysis, fault tracing, and centralized control of production status.

[0042] Specifically, such as Figure 3 , Figure 5 and Figure 11 As shown, the electrostatic collection structure 2 also includes: Flexible dielectric film 22; Collector 23 is arc-shaped overall; An insulating protective component 24 is wrapped around the outer edge of the C-shaped ceramic component 21, and a support rod 25 is provided at one end. The outer wall of the C-shaped ceramic part 21 is provided with a receiving groove 221. The flexible dielectric film 22 and the collector electrode 23 are arranged in the receiving groove 221 from the inside to the outside. When the fishing line rubs against the inner wall of the C-shaped ceramic part 21 to generate static electricity, the charge is coupled to the collector electrode 23 through the flexible dielectric film 22 to realize static electricity collection.

[0043] More specifically, energy storage units include: Supercapacitor 31; The rectifier circuit is electrically connected to the input terminal of the supercapacitor 31; The electrostatic discharge protection circuit is electrically connected between the rectifier circuit and the collector 23. The driving circuit is electrically connected to the output terminal of the supercapacitor 31; When the collector 23 outputs an alternating electrostatic signal, the electrostatic discharge protection circuit can promptly discharge the instantaneous high-voltage electrostatic surge. The electrostatic signal, after protection processing, is sent to the rectifier circuit, which converts the alternating electrostatic signal into DC power and continuously charges and stores it in the supercapacitor 31.

[0044] In this embodiment, the fishing line continuously rubs against the inner wall of the C-shaped ceramic component 21 during high-speed travel, generating electrostatic charges. A flexible dielectric film 22 is arranged between the C-shaped ceramic component 21 and the collector 23. The electrostatic charges generated by friction are conducted to the collector 23 through the electric field coupling effect of the flexible dielectric film 22, thereby completing the electrostatic signal acquisition. When the collector 23 outputs an alternating electrostatic signal, the instantaneous high-voltage electrostatic surge can easily impact the downstream rectifier and energy storage components. The electrostatic discharge protection circuit can quickly discharge the high-voltage surge, suppress the spike pulse, and provide reliable protection for the subsequent circuits. The electrostatic signal after protection is sent to the rectifier circuit, which will convert the alternating electrostatic signal into a static signal. The electrostatic signal is converted into stable DC power. The DC power output by the rectifier circuit continuously charges the supercapacitor 31. The power is stored inside the supercapacitor 31 and serves as the driving energy for the actuator 6. By collecting and dispersing the static electricity generated by friction in real time, the charge is prevented from accumulating on the surface of the fishing line. This eliminates the basic conditions for static electricity to adsorb dust and fiber debris, effectively improves the cleanliness of the fishing line surface, reduces detection errors caused by pollutants, and further improves the accuracy of line breakage and defect monitoring. It converts the harmful static electricity that originally caused dust accumulation, discharge interference, and detection baseline drift into storable and usable power, realizing the recovery and reuse of static electricity energy. Meanwhile, the flexible dielectric film 22 and the collector 23 do not come into direct contact with the fishing line throughout the process, so they will not scratch the surface of the fishing line and form scratch-like false defects. This ensures that the transmission infrared detection module 4 and the high-speed vision detection module 32 can collect real and effective images and optical signals, maintain detection accuracy, and the whole structure has no continuous mechanical friction loss, which effectively extends the service life of the flexible dielectric film 22 and the collector 23, reduces the frequency of later inspection and replacement, and reduces the workload of daily maintenance.

[0045] It should be noted that the collector 23 is electrically connected to the input terminal of the electrostatic discharge protection circuit on the circuit board 3 via a flexible wire. Specifically, a soldering terminal is led out from the collector 23 on the C-shaped ceramic component 21, and this soldering terminal is connected to the input interface of the circuit board 3 via an insulated wire. The input interface on the circuit board 3 is electrically connected to the electrostatic discharge protection circuit. The alternating electrostatic signal collected by the collector 23 is transmitted to the circuit board 3 via this wire, and is processed by the electrostatic discharge protection circuit and the rectifier circuit in sequence before charging the supercapacitor 31. The energy storage unit employs a conventional energy harvesting and management circuit architecture. Specifically, collector 23 is connected to the input interface on circuit board 3 via a flexible wire. The alternating electrostatic signal output from collector 23 is first subjected to surge suppression by a transient voltage suppression diode and a discharge resistor connected in parallel through an electrostatic discharge protection circuit. Then, it is converted into DC power by a full-wave bridge rectifier structure through a rectifier circuit to charge and store the supercapacitor 31. The drive circuit uses a DC-DC boost converter, specifically an LTC3105 or a similar micropower boost chip, to boost the energy stored in the supercapacitor 31 to the operating voltage required by the push-pull electromagnet 61. Its enable terminal is controlled by the main control module. All of the above circuit modules are common knowledge in the art, and their specific implementation methods can be selected and configured by those skilled in the art according to actual needs, and will not be elaborated here.

[0046] Specifically, such as Figure 6 , Figure 7 and Figure 8 As shown, execution structure 6 includes: The push-pull electromagnet 61 is electrically connected to the output terminal of the drive circuit; The drive rack 64 is located on one side of the push-pull electromagnet 61 and can slide on the support base plate 11. Connecting arm 65 is connected between the output push rod of push-pull electromagnet 61 and drive rack 64; The rotating component 62 has an arc-shaped groove that can constrain the drive rack 64, and the arc-shaped groove is provided with a plurality of teeth 621 that mesh with the drive rack 64; The rotating shaft 63 is rotatably disposed in the execution chamber, with one end connected to the rotating component 62; Pull rod 66 is detachably connected to one side of connecting arm 65; The drive rack 64 has a relief groove 641 and a movable groove 642 communicating with the relief groove 641. A slot 643 is provided on one side of the movable groove 642. When the push-pull electromagnet 61 is energized, the output push rod pushes the drive rack 64, and the drive rack 64 meshes with the teeth 621 on the rotating part 62 to drive the rotating part 62 to rotate around the axis. During the rotation of the rotating part 62, the corresponding C-shaped ceramic part 21 swings synchronously, realizing the opening and closing of the ceramic guide eye.

[0047] In this embodiment, after the ultrasonic sensor 5 detects a broken fishing line, it uploads the detection signal to the main control module. The main control module issues a fault trigger command, controlling the energy storage unit to supply power to the push-pull electromagnet 61. The push-pull electromagnet 61 is energized and starts, and the output push rod pushes the drive rack 64 to produce displacement. The drive rack 64 meshes with the teeth 621 on the rotating part 62, driving the rotating part 62 to rotate around the axis. When the rotating part 62 rotates, it synchronously drives the corresponding C-shaped ceramic part 21 to swing outward and open, and the ceramic guide eye opens accordingly. After the fault is cleared, the actuator 6 drives the transmission mechanism to move in the opposite direction, causing the C-shaped ceramic part 21 to reset and close, forming a fishing line passage guide channel again. The actuator 6 drives the C-shaped ceramic part 21 to open outward, making the line area radially open. When workers carry out line breakage replacement and clear stuck wires, there is no need to thread long lines along the fishing line axis or pull the wires with brute force. Fishing lines can be loaded and unloaded directly from the side, simplifying the cleaning operation process, effectively shortening the equipment downtime, and ensuring the continuous and stable operation of the fishing line winding production line. When the energy storage unit has insufficient stored energy and cannot rely on the push-pull electromagnet 61 to drive the mechanism, the staff manually pulls the lever 66. The lever 66 drives the rack 64 to complete the displacement transmission in sync. Relying on manual mechanical driving force, the transmission mechanism is driven to swing and open / close the C-shaped ceramic parts 21 on both sides, realizing the opening and closing of the ceramic guide eye. Even if the power shortage causes the electric drive to fail, the line routing area can still be opened to the side, making it convenient for personnel to clean broken lines and load and unload fishing lines. This avoids the problem of the mechanism being unable to open or the equipment being locked and unable to be repaired due to insufficient stored energy, improves the fault tolerance of the device, and ensures that on-site maintenance work can be carried out smoothly under fault conditions.

[0048] Specifically, such as Figure 8 , Figure 9 and Figure 10 As shown, a locking assembly 67 is provided on one side of the drive rack 64. The locking assembly 67 includes: The deflector 671 has a retaining post 675 located within the relief groove 641; Support member 674 is L-shaped and is mounted on support base plate 11; The rotating shaft 672 is rotatably mounted on the support member 674; The torsion spring 673 is sleeved outside the rotating shaft 672 and connected between the deflecting member 671 and the support member 674. When the drive rack 64 moves, it forces the locking pin 675 to disengage from the slot 643 and slide into the movable slot 642. The locking pin 675 slides along the movable slot 642 to another slot 643 position. The torsion spring 673 releases torque to drive the deflector 671 to rotate, so that the locking pin 675 is locked into the slot 643, thus completing the locking of the drive rack 64 position.

[0049] In this embodiment, when the drive rack 64 moves, it forces the locking pin 675 to disengage from the current slot 643 and slide into the movable slot 642. The locking pin 675 continues to slide along the inside of the movable slot 642 until it aligns with the position of another slot 643. The torsion spring 673 releases the stored torque to drive the deflector 671 to rotate, pushing the locking pin 675 to extend into and engage with the slot 643, thus completing the position locking of the drive rack 64. This stably maintains the open or closed state of the C-shaped ceramic part 21. There is no need for the push-pull electromagnet 61 to be continuously energized to maintain the thrust. The electromagnet only needs to output power momentarily to complete the position switching. After reaching the position, the mechanical locking structure maintains the position, which greatly reduces power consumption and reduces the power supply load of the energy storage unit. At the same time, the locking and positioning are reliable and can resist the position deviation caused by equipment vibration and working condition impact. This effectively avoids the unexpected rebound and swing of the C-shaped ceramic part 21, ensures the stability of the guide structure, and improves the reliability of the device operation.

[0050] Specifically, such as Figure 1 and Figure 6 As shown, it also includes a connection structure disposed between the electrostatic collection structure 2 and the actuation structure 6, the connection structure including: The upper connecting rod 8 has one end detachably connected to the support rod 25; The lower connecting rod 7 is detachably connected to the rotating part 62 at one end and connected to the upper connecting rod 8 at the other end.

[0051] In this embodiment, the connection structure adopts a detachable assembly combination. The modular split assembly structure makes it convenient for each component to be processed and formed independently, making assembly, positioning and adjustment more convenient. The parts can be disassembled independently, making maintenance more convenient.

[0052] Specifically, such as Figure 1 and Figure 4 As shown, the execution chamber is formed by the outer wall of the central receiving chamber, the side plate 17 and the enclosure plate 14. The enclosure plate 14 has a movable hole, and an elastic protective ring 9 is provided on one side of the movable hole. The elastic protective ring 9 is sleeved on the lower connecting rod 7. The side plate 17 has a through hole, and the pull rod 66 can slide within the through hole.

[0053] In this embodiment, the elastic protective ring 9 prevents dust and lint from entering the execution chamber, avoiding interference from foreign objects with the execution structure 6. At the same time, it has an elastic buffering effect, which can buffer the swing impact of the lower connecting rod 7, reduce friction noise, and maintain the smooth swing transmission of the lower connecting rod 7.

[0054] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, the detection structure includes: A high-speed vision inspection module 32 is mounted on circuit board 3; The transmission infrared detection module 4 has an infrared emitting unit and an infrared receiving unit; Ultrasonic sensor 5, which has an ultrasonic probe; The circuit board 3 has a main control module, which is electrically connected to the high-speed vision inspection module 32, the transmission infrared inspection module 4, and the ultrasonic sensor 5.

[0055] In this embodiment, during the movement of the fishing line, the high-speed vision inspection module 32 continuously collects image information of the fishing line surface, accurately identifying various surface defects such as scratches, damage, unevenness, and inconsistent thickness. At the same time, the infrared beam emitted by the transmission infrared detection module 4 can penetrate the fishing line. When there are internal defects such as dark cracks, bubbles, or impurities inside the fishing line, the light propagation path is scattered and refracted, causing significant fluctuations in the light path signal collected by the infrared receiving unit. This allows for the identification of internal defects that cannot be directly observed by the naked eye, such as dark cracks, bubbles, and impurities inside the fishing line. The ultrasonic sensor 5 monitors the position of the fishing line in real time based on the ultrasonic ranging and echo sensing principle, completing the detection of line breakage. The line breakage detection is linked with the execution structure 6. Once a line breakage is detected, the main control module immediately outputs a linkage control signal to activate the execution structure 6, causing the C-shaped ceramic part 21 to swing outward and open, opening the line routing area laterally, making it easier for staff to quickly clean broken wires and handle line jamming faults.

[0056] It should be noted that the detection structure and circuit board 3 are continuously powered by an external power supply to ensure the continuous and stable operation of the infrared transmission detection module 4, ultrasonic sensor 5, and communication module. This is not affected by the operation of the electrostatic collection and energy storage unit, ensuring that the entire online monitoring and control system can work continuously around the clock. The energy of the energy storage unit is only dedicated to providing instantaneous drive power for the push-pull electromagnet 61 of the actuator 6, realizing graded energy utilization and distinguishing between the two energy circuits for the power supply of the detection system and the power supply for the mechanism action, so that they do not interfere with each other and improve the operational stability of the entire device.

[0057] More specifically, the base 12 and the bracket 13 each have a detection window and a detection slot. A light-transmitting plate 15 is mounted on the detection window, and a light-transmitting plate 26 is provided on one side of the detection slot. The infrared transmission detection module 4 and the ultrasonic sensor 5 are installed in the detection slot. The light-transmitting plate 15 and the light-transmitting plate 26 do not affect the signal acquisition of the infrared transmission detection module 4 and the ultrasonic sensor 5, ensuring the continuous and effective operation of online defect detection. At the same time, the light-transmitting plate 15 and the light-transmitting plate 26 form a protective barrier to prevent dust, floating lint, and debris from entering the detection area and the vicinity of the sensing components, avoiding contaminants from directly adhering to the infrared transmission light path channel and the surface of the sensing probe, and reducing false alarms caused by the light path being blocked by foreign objects.

[0058] Working principle: During the movement of the fishing line, the high-speed vision inspection module 32 continuously collects image information of the fishing line surface, accurately identifying various surface defects such as scratches, damage, unevenness, and inconsistent thickness. Simultaneously, the infrared beam emitted by the transmission infrared detection module 4 can penetrate the fishing line. When internal defects such as dark cracks, bubbles, or impurities exist within the fishing line, the light propagation path is scattered and refracted, causing significant fluctuations in the light path signal collected by the infrared receiving unit. This allows for the identification of internal defects that are not directly observable to the naked eye, such as dark cracks, bubbles, and impurities. Line breakage is detected by the ultrasonic sensor 5. During high-speed movement, the fishing line continuously rubs against the inner wall of the C-shaped ceramic component 21, generating electrostatic charges. The electrostatic film 22 is arranged between the C-shaped ceramic part 21 and the collector 23. The electrostatic charge generated by friction is conducted to the collector 23 through the electric field coupling effect of the flexible dielectric film 22, thereby completing the electrostatic signal acquisition. When the collector 23 outputs an alternating electrostatic signal, the instantaneous high voltage electrostatic surge is prone to impacting the downstream rectifier and energy storage components. The electrostatic discharge protection circuit can quickly discharge the high voltage surge, suppress the spike pulse, and provide reliable protection for the subsequent circuit. The electrostatic signal after protection is sent to the rectifier circuit. The rectifier circuit converts the alternating electrostatic signal into stable DC power. The DC power output by the rectifier circuit continuously charges the supercapacitor 31. The power is stored inside the supercapacitor 31 as the driving energy for the actuator 6. After the ultrasonic sensor 5 detects a broken fishing line, it uploads the detection signal to the main control module. The main control module then issues a fault trigger command, controlling the energy storage unit to supply power to the push-pull electromagnet 61. The push-pull electromagnet 61 is energized and starts, and the output push rod pushes the drive rack 64 to produce displacement. The drive rack 64 meshes with the teeth 621 on the rotating part 62, driving the rotating part 62 to rotate around the axis. When the rotating part 62 rotates, it synchronously drives the corresponding C-shaped ceramic part 21 to swing outward and open, and the ceramic guide eye opens accordingly. After the fault is cleared, the execution structure 6 drives the transmission mechanism to move in the opposite direction, driving the C-shaped ceramic part 21 to reset and close, forming a fishing line passage guide channel again. By driving the C-shaped ceramic part 21 to open outward through the execution structure 6, the line-carrying area is radially open, after which workers can carry out broken line replacement and clear stuck wires.
