Description

Technical Field

[0001] The invention relates to the technical field of optical fiber production, in particular to a production device and a production process of a high-strength ultra-fine optical fiber for an industrial endoscope. Background Art

[0002] In the application field of industrial endoscopes, high-strength ultra-fine optical fibers play a vital role as key components. This type of optical fiber has the unique characteristics of high strength and ultra-fineness. The high-strength characteristics enable it to work normally in harsh industrial environments. Harsh and complex working conditions such as high temperature, high pressure, high corrosion and high vibration will not cause damage or performance degradation to it, ensuring the stability of information transmission during industrial inspections, and providing a solid guarantee for the continuity and reliability of inspection work. At the same time, its ultra-fine characteristics allow it to easily pass through the narrow channels of industrial endoscopes and penetrate into various small spaces and complex structures, such as pipelines, containers, engine internal structures, and internal parts of aerospace equipment. Areas that are difficult to reach by conventional inspection methods, thereby achieving in-depth inspections. Moreover, the optical fiber is made of special materials, has excellent flexibility, can be bent and twisted, and can be flexibly adjusted according to inspection paths of different shapes and angles, greatly expanding the inspection range and application scenarios of industrial endoscopes.

[0003] However, when producing and processing high-strength ultra-fine optical fibers for industrial endoscopes, a more traditional operating mode is currently used. It is usually necessary to temporarily coil multiple optical fibers and hang them on a support frame before performing quality inspection or other processing. During the coiling period, the optical fiber coil on the support frame is placed on the hook on the stand, and then the multiple optical fibers are processed one by one. This processing mode has many problems. On the one hand, hanging the coil that does not need to be processed immediately on the stand will occupy a large amount of stand space, making the originally spacious stand operation area crowded and causing inconvenience to the operation. In addition, the coil has multiple optical fiber connectors, which will be placed in a disorderly manner on the stand, which not only affects the cleanliness of the working environment, but also interferes with the normal operation process of employees. When employees carry out precision optical fiber processing, During fine processing, such as cutting, connecting and testing, these redundant fiber connectors can easily cause obstacles during the operation, leading to operational errors, affecting processing accuracy, and even damaging the optical fiber being processed. In order to ensure the normal progress of work, employees have to frequently move the wire balls back and forth between the bench and the support frame. During this process, they need to carefully move the wire balls to ensure that they are in the proper position to avoid collision damage. After the processing is completed, the wire balls must be safely moved back to the support frame. The whole process requires a lot of time and energy, and the position of the wire balls needs to be constantly adjusted to prevent the wire balls from being entangled and rubbed to cause damage to the optical fiber. This cumbersome operation process increases the burden on employees, greatly reduces production efficiency, hinders the normal progress of industrial production, and has a negative impact on the production efficiency of the enterprise;

[0004] In order to improve this situation, a Chinese patent with the announcement number "CN207020372U" discloses a workbench for optical fiber processing. The workbench adopts an innovative design. By buckling the hook groove of the wire hanging rack and the sliding rack with a push component, and setting a switch panel, employees can use it to control the movement of the wire hanging rack on the console; the wire hanging branch is connected to the wire hanging rack through the adjustment component. When processing the optical fiber coil, the employee only needs to turn the wire hanging branch to replace the next coil to be processed, without manually turning the coil. This design facilitates the operation to a certain extent and has the advantages of saving time and effort;

[0005] However, the device disclosed in the patent still has obvious shortcomings in actual use. When winding the optical fiber, it often has to rely on manual operation. The winding process is relatively cumbersome, and the optical fiber is very likely to loosen when it is manually rotated for winding. In addition, the distance between its various hanging wire branches is too close, which can easily cause multiple optical fibers to be entangled with each other during use. Once entangled, it is difficult to untie the optical fiber during subsequent processing, which will seriously affect the normal production and processing of the optical fiber. In view of the above situation, it is necessary to further improve the design of the existing optical fiber processing device to overcome the many problems existing in the prior art, improve the efficiency and quality of optical fiber processing, and meet the higher requirements of the production and processing of high-strength ultra-fine optical fibers for industrial endoscopes.

[0017] A production process of high-strength ultra-fine optical fiber for industrial endoscopes, comprising the following steps:

[0018] S1: Raw material preparation, special glass or plastic raw materials are selected, and after purity testing, impurities are removed through pre-treatment such as filtration and cleaning. According to the characteristics of optical fiber, the basic raw materials are prepared in a specific proportion (such as 80%-90% of silica in glass raw materials);

[0019] S2: Wire drawing process: the pre-treated raw materials are put into a high-temperature furnace at 1800-2000℃. After being completely melted, they are drawn into fiber filaments at a speed of 10-20m / s and a temperature of 1500-1700℃ using precision wire drawing equipment. Argon gas protection is used to prevent pollution and oxidation.

[0020] S3: Coiling and preliminary fixation: start the coiling mechanism, turn on the third motor, drive the elastic group and the adjustment rail, and evenly coil the drawn optical fiber on the coiling rack at a speed of 5-10r / min. During the coiling process, dynamically adjust the coiling tension according to the thickness and material characteristics of the optical fiber to ensure that the tension is controlled at 1-3N to ensure that the optical fiber is coiled tightly and neatly. Each adjustable coiler reels multiple strands of optical fiber at the same time. After the coiling is completed, use a fixing clamp to preliminarily fix it to prevent the optical fiber from loosening.

[0021] S4: Secondary processing and performance optimization. Start the second motor and drive the adjustment disk to rotate at a speed of 3-5r / min, so that the adjustable coiler alternates to the front end in turn. In the coiled state, the optical fiber is subjected to surface coating treatment, and the coating thickness is controlled at 0.05-0.1mm; or stretched, and the tensile stress is controlled at 50-80MPa. During the processing, the coiling state is continuously monitored to ensure that the optical fiber is stably processed for secondary processing with the assistance of coiling, so as to avoid loosening or uneven force of the optical fiber due to processing;

[0022] S5: Quality inspection, use professional equipment to test optical performance, requiring optical transmission loss less than 0.5dB / km, bandwidth greater than 500MHz·km; mechanical performance inspection tensile strength not less than 500MPa, bending strength not less than 300MPa; appearance inspection with a 5-10x magnifying glass, no obvious defects or scratches allowed;

[0023] S6: Packaging and storage: The qualified optical fiber shall be packed in vacuum or filled with nitrogen with a purity of more than 99.9% according to the specification of 500-1000m per roll, and stored in a dry and cool environment with a temperature of 20±5℃ and a relative humidity below 50%.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] First, in the present invention, by setting an adjustment mechanism, during use, the first motor can be used to drive the first screw to rotate, and the power of the screw rotation is transmitted to the movable block, pushing it to slide smoothly along the guide rail. This sliding causes the lateral position of the linear displacement mechanism installed on the top of the movable block to change accordingly, thereby driving the winding mechanism to achieve lateral displacement adjustment. At the same time, the fourth motor in the power assembly runs, driving the gear and the gear ring to interact, driving the movable block connected to the side frame to move forward and backward, thereby driving the winding mechanism to move forward and backward. With such a design, the winding mechanism can flexibly change its position in multiple dimensions, and the user can quickly and accurately adjust the winding mechanism according to different work requirements, which greatly improves the convenience and operational flexibility of the device, so that it can effectively adapt to various work scenes;

[0026] Secondly, in the present invention, when in use, the optical fiber to be processed is wound on the winding frame, and then the third motor is started, the motor drives the elastic group to operate, and the elastic group drives the adjustment rail to rotate. Under this series of power transmission, the optical fiber is smoothly wound, and each adjustable winder is independently set and can be adjusted separately by the third motor, so that each winder can independently complete the winding work of multiple optical fibers, which greatly improves the convenience of using the device. During the processing process, the second motor is started to drive the adjustment disk to rotate, and the rotation of the adjustment disk causes the various adjustable winders at the bottom of the adjustment disk to rotate alternately to the front end in turn, thereby realizing rapid and uninterrupted processing of the optical fiber. Through this cyclic adjustment, the convenience of production and processing is further improved;

[0027] Thirdly, in the present invention, during the use of the device, the buffer torsion spring can effectively buffer the force it is borne and reduce the risk of damage to the equipment due to external force impact. The user twists the button handle to drive the second screw to rotate. The threads at both ends of the second screw have opposite rotation directions. When rotating, it can synchronously drive the slider to reciprocate on the adjustment rail, thereby driving the winding frame on the frame to achieve spacing adjustment. During this adjustment process, the optical fiber is squeezed and expanded, and the winding frame squeezes the expansion spring. The expansion spring continues to provide stable elastic force to maintain the squeezing of the optical fiber and improve the stability of the optical fiber. In addition, each adjustable winder is independently arranged and has good elasticity. It can evenly apply elastic force to the optical fiber, so that the optical fiber is always in a taut state, effectively reducing the probability of entanglement, and significantly improving the stability, quality and efficiency of optical fiber production and processing.

DETAILED DESCRIPTION

[0038] Example

[0039] See also Figure 1-Figure 9 In an embodiment of the present invention, a production device for high-strength ultra-fine optical fiber for industrial endoscopes includes a workbench 1, support frames 2 are fixedly installed on both sides of the bottom of the workbench 1, a mounting frame 4 is fixedly installed on the top rear side of the workbench 1, an adjustment mechanism 5 is fixedly installed on the top of the mounting frame 4, a linear displacement mechanism 3 is fixedly installed on the top of the adjustment mechanism 5, and a winding mechanism 6 is fixedly installed on the front end of the linear displacement mechanism 3;

[0040] The winding mechanism 6 includes an adjustment component 61, which is fixedly connected to the front end of the linear displacement mechanism 3. A rotating component 62 is fixedly installed at the bottom of the adjustment component 61, and a winding component 63 is fixedly installed at an equal interval on the top of the rotating component 62. The support frames 2 on both sides of the bottom of the workbench 1 play a role of stable support. When the work starts, the adjustment mechanism 5 on the mounting frame 4 is started, and the linear displacement mechanism 3 connected thereto is driven to move in the horizontal direction through the internal power device, such as a motor driving the screw rod and other structures to operate, so as to adjust the lateral position of the winding mechanism 6 at the front end of the linear displacement mechanism 3. When the winding mechanism 6 reaches the specified position, the adjustment component 61 plays a role. It may control the rotation component 62 to rotate through the gear 325 transmission, hydraulic drive and other methods, and the winding components 63 evenly distributed on the top of the rotating component 62 rotate accordingly. The optical fiber introduced from the outside is driven by the winding component 63 and is wound on the winding component 63 at a specific path and speed, so as to realize the winding operation of the optical fiber, complete the preliminary processing and positioning of the optical fiber on the device, and facilitate the subsequent processing.

[0041] See also Figure 1-Figure 3The adjustment mechanism 5 includes a guide rail 51, which is fixedly mounted on the top of the mounting frame 4. The guide rail 51 is rotatably connected to a first screw rod 52. The outer surface of the first screw rod 52 is threadedly connected to a movable block 53. The top of the movable block 53 is connected to the bottom of the linear displacement mechanism 3. One end of the guide rail 51 is fixedly connected to a first motor 7. The output end of the first motor 7 is connected to the end of the first screw rod 52. The linear displacement mechanism 3 includes a rail frame 31, which is fixedly mounted on the top of the movable block 53. A power assembly 32 is provided on one side of the rail frame 31. A connecting rod 3 is installed on the front side of the power assembly 32. 3, the outer end of the connecting rod 33 is connected to the adjustment component 61, the power component 32 includes a sliding block 321 and a rack 322, the sliding block 321 is slidably connected to the inside of the side rail, the rack 322 is fixedly connected to one side of the rail frame 31, one side of the sliding block 321 is fixedly connected to the side frame 323, the outer side of the side frame 323 is fixedly connected to the fourth motor 324, the output end of the fourth motor 324 passes through the side frame 323 and is fixedly connected to the gear 325, the gear 325 and the rack 322 are meshed and connected, the front side of the sliding block 321 is fixedly connected to the rear end of the connecting rod 33, when the position needs to be adjusted, the first motor 7 is started, and its output end drives the first screw rod 52 connected thereto to rotate in the guide rail 51. Since the first screw rod 52 is threadedly connected to the movable block 53, as the screw rod rotates, the movable block 53 moves along the axial direction of the screw rod inside the guide rail 51, and the power member fixedly connected to the top of the movable block 53 moves accordingly, providing basic support for subsequent actions; and the power assembly 32 in the linear displacement mechanism 3 also starts to work at this time, and the fourth motor 324 on the outer side of the side frame 323 is started, and the gear 325 at its output end rotates accordingly. Since the gear 325 is meshed with the rack 322 fixed on one side of the rail frame 31, The rotation of the gear 325 causes the sliding block 321 connected thereto to slide in the side rail of the rail frame 31. The connecting rod 33 fixedly connected to the front of the sliding block 321 will move with the movement of the sliding block 321, and the outer end of the connecting rod 33 is connected to the adjusting component 61, so that the position of the adjusting component 61 is adjusted, thereby driving the entire winding mechanism 6 to move forward and backward or in other directions to meet different production needs. Through the mutual cooperation of the adjusting mechanism 5 and the linear displacement mechanism 3, the position of the winding mechanism 6 can be accurately controlled, providing a stable and flexible operating platform for optical fiber processing.

[0042] See also Figure 4-Figure 5 and Figure 7The adjusting component 61 includes a sleeve frame 611, which is fixedly installed on the front end of the connecting rod 33. The sleeve frame 611 is slidably connected to the sliding rod 612 inside. The front of the sliding rod 612 is threadedly connected with a hand-tightened screw 613. The end of the hand-tightened screw 613 passes through the sleeve frame 611 and is connected to the sliding rod 612. The front of the sliding rod 612 is linearly arranged with equal intervals to provide limited position holes. The end of the hand-tightened screw 613 is inserted into the inner side of the limited position hole. The sleeve frame 611 slides with the sliding rod 612 at its bottom to adjust the length of the entire adjusting component 61, so that the height of the winding mechanism 6 can be adjusted. When the height of the winding mechanism 6 needs to be adjusted, the adjusting component 61 comes into play. First, the sleeve frame 611 fixedly installed on the front end of the connecting rod 33 provides a basic frame 6334 for the entire adjusting component 61. The interior of the sleeve frame 611 is slidably connected to the sliding rod 612, and the sliding rod 612 can slide linearly in the sleeve frame 611 , since the hand-tightened screw 613 is threadedly connected to the front of the sliding rod 612, and its end passes through the sleeve frame 611, during the adjustment process, by rotating the hand-tightened screw 613, as the screw rotates, the hand-tightened screw 613 will push the sliding rod 612 to adjust its position in the sleeve frame 611, and the front of the sliding rod 612 is provided with limiting holes arranged linearly at equal intervals. When the sliding rod 612 slides to a suitable position, the end of the hand-tightened screw 613 is inserted into the corresponding limiting hole to fix the position of the sliding rod 612. The sleeve frame 611 cooperates with the sliding of the bottom sliding rod 612 to achieve the adjustment of the length of the entire adjustment component 61. Because the adjustment component 61 is closely connected to the winding mechanism 6, the change in the length of the adjustment component 61 also achieves the height adjustment of the winding mechanism 6, thereby meeting the diverse requirements for the height of the winding mechanism 6 in different production scenarios, and ensuring that the optical fiber can be accurately wound during the processing process.

[0043] See also Figure 4-Figure 9The rotating assembly 62 includes a connecting frame 621, which is fixedly connected to the bottom of the sliding rod 612. The rear end of the connecting frame 621 is fixedly connected to a second motor 622. An adjusting disk 623 is fixedly installed at the output end of the second motor 622. The winding assembly 63 is arranged in a ring shape at equal intervals and installed at the bottom of the adjusting disk 623. The winding assembly 63 includes a third motor 631. The third motor 631 is arranged in a ring shape at equal intervals and fixedly connected to the top of the adjusting disk 623. The output end of the third motor 631 passes through the adjusting disk 623 and is fixedly connected to an elastic group 632. An adjustable coiler 633 is provided at the bottom of the elastic group 632. The elastic group 632 includes a sleeve 6321, the sleeve 6321 is fixedly connected to the bottom output end of the third motor 631, a buffer torsion spring 6322 is fixedly installed inside the sleeve 6321, a turntable 6323 is fixedly installed at the bottom of the buffer torsion spring 6322, the bottom of the turntable 6323 is connected to the top of the adjustable coiler 633, the adjustable coiler 633 includes an adjustment rail 6331, the adjustment rail 6331 is fixedly connected to the bottom of the turntable 6323, the adjustment rail 6331 is rotatably connected to the inside of the second screw rod 6332, the two ends of the second screw rod 6332 are screwed in opposite directions, the two ends of the second screw rod 6332 are threadedly connected to the slider 6333, the bottom of the slider 6333 The frame 6334 is fixedly connected to the bottom, and a telescopic spring 6335 is arranged inside the frame 6334.

The bottom of the base block 6336 is fixedly connected to a winding rack 6337. The side shape of the winding rack 6337 is L-shaped. The end of the second screw rod 6332 passes through the adjustment rail 6331 and is fixedly connected to a button handle 6338. The connecting frame 621 is fixed to the bottom of the sliding rod 612. When the optical fiber winding operation is required, the second motor 622 at the rear end of the connecting frame 621 is started, and its output end drives the adjusting disk 623 to rotate. The coiling components 63 arranged in a ring shape at equal intervals at the bottom of 623 rotate synchronously therewith to achieve position switching. Specifically, with respect to the coiling components 63, taking one of them as an example, the third motor 631 fixed on the top of the adjusting disk 623 is turned on, and its output end drives the elastic group 632 connected thereto to operate, and the sleeve 6321 of the elastic group 632 rotates with the output end of the third motor 631. The buffer torsion spring 6322 inside the sleeve 6321 plays a buffering role. When subjected to external force impact or torque changes, it can effectively absorb energy to ensure the stability of rotation. The rotating disk 6323 at the bottom of the buffer torsion spring 6322 rotates accordingly, thereby driving the adjustable coiler 633 at the bottom to work;

The second screw rod 6332 connected to the adjusting rail 6331 is rotated, and the threads at both ends are rotated in opposite directions. The knob 6338 at the end of the second screw rod 6332 is rotated, and the second screw rod 6332 rotates accordingly. Due to its special thread design, the slider 6333 connected to the threads at both ends will move towards or away from each other in the adjusting rail 6331, and the frame 6334 connected to the bottom of the slider 6333 will move accordingly. The telescopic spring 6335 inside the frame 6334 is at the base. Block 6336 is compressed or stretched when sliding, and continuously provides elastic force. The L-shaped winding frame 6337 connected to the bottom of the base block 6336 can play a good limiting role, avoid the coiled optical fiber from falling off, and improve the stability of the optical fiber winding. Under the action of the movement of the frame 6334 and the elastic force of the telescopic spring 6335, the spacing adjustment is achieved. Multiple groups of winding assemblies 63 work at the same time, and multiple optical fibers can be stably coiled to meet production needs. The coordinated design of the buffer torsion spring 6322 and the telescopic spring 6335 can play a good buffering role.

[0045] A production process of high-strength ultra-fine optical fiber for industrial endoscopes, comprising the following steps:

[0046] S1: Raw material preparation, special glass or plastic raw materials are selected, and after purity testing, impurities are removed through pre-treatment such as filtration and washing. According to the characteristics of optical fiber, the basic raw materials are formulated in a specific ratio, such as 80%-90% of silica in glass raw materials;

[0047] S2: Wire drawing process: the pre-treated raw materials are put into a high-temperature furnace at 1800-2000℃. After being completely melted, they are drawn into fiber filaments at a speed of 10-20m / s and a temperature of 1500-1700℃ using precision wire drawing equipment. Argon gas protection is used to prevent pollution and oxidation.

[0048] S3: Coiling and preliminary fixation, the coiling mechanism 6 is activated, the third motor 631 is turned on, and the elastic group 632 and the adjustment rail 6331 are driven to evenly coil the drawn optical fiber on the coiling frame 6337 at a speed of 5-10r / min. During the coiling process, the tension of the coiling is dynamically adjusted according to the thickness and material characteristics of the optical fiber to ensure that the tension is controlled at 1-3N, so that the optical fiber is coiled tightly and neatly.

During the processing, the coiling state is continuously monitored to ensure that the optical fiber is stably subjected to secondary processing with the assistance of coiling, so as to avoid loosening or uneven force of the optical fiber caused by processing;

[0050] S5: Quality inspection, use professional equipment to test optical performance, requiring optical transmission loss less than 0.5dB / km, bandwidth greater than 500MHz·km; mechanical performance inspection tensile strength not less than 500MPa, bending strength not less than 300MPa; appearance inspection with a 5-10x magnifying glass, no obvious defects or scratches allowed;

[0051] S6: Packaging and storage: The qualified optical fiber shall be packed in vacuum or filled with nitrogen with a purity of more than 99.9% according to the specification of 500-1000m per roll, and stored in a dry and cool environment with a temperature of 20±5℃ and a relative humidity below 50%.

[0052] The working principle of the present invention is as follows: in the present invention, the ingenious design of the adjustment mechanism 5 greatly improves the user experience of the device. When the first motor 7 is started, the operation of the motor drives the first screw rod 52 to rotate synchronously. The rotation of the screw rod causes the movable block 53 to slide smoothly along the guide rail 51. As the movable block 53 moves in the guide rail 51, the lateral position of the linear displacement mechanism 3 installed on the top thereof can be flexibly adjusted, and the movement of the linear displacement mechanism 3 further realizes the lateral displacement adjustment of the winding mechanism 6.

[0053] At the same time, when the first motor 7 in the power assembly 32 is running, it drives the gear 325 to rotate at a high speed. Since the gear 325 is tightly meshed with the gear ring, as the gear 325 continues to rotate, the movable block 53 connected to the side frame 323 will move forward and backward. The forward and backward movement of the movable block 53 drives the winding mechanism 6 to adjust the forward and backward displacement. In this way, during the actual use of the device, the position of the winding mechanism 6 can be flexibly changed in all directions and dimensions, which greatly improves the overall convenience and operational flexibility of the device, allowing the user to quickly and accurately adjust the position of the winding mechanism 6 according to different work requirements to adapt to a variety of work scenarios;

[0054] The winding mechanism 6 of the present invention is the key to achieving efficient and stable optical fiber processing. In actual use, the optical fiber to be processed can be conveniently wound on the winding frame 6337, and the third motor 631 is started. The motor drives the elastic group 632 to start rotating. The rotation of the elastic group 632 drives the adjustment rail 6331 at the bottom thereof to rotate synchronously. In this process, the optical fiber can be smoothly wound onto the winding frame 6337. It is worth mentioning that each adjustable winder 633 is independently set, and each winder can be independently adjusted by the third motor 631. This feature enables each winder to independently complete the winding work of multiple optical fibers, which greatly improves the convenience of using the device.

[0055] During the optical fiber processing process, the second motor 622 is started, and the motor drives the adjustment disk 623 to rotate. The rotation of the adjustment disk 623 enables the various adjustable winding devices 633 at the bottom thereof to rotate and move to the front end position in sequence. This ingenious design enables the device to realize fast and uninterrupted processing of optical fibers. Through the reciprocating adjustment method, the convenience of the device production and processing is further improved.

[0056] During the entire use process, the force exerted on the device will act on the buffer torsion spring 6322, and the buffer torsion spring 6322 can effectively buffer these forces, thereby providing a good buffering protection effect for the device and reducing the risk of equipment damage caused by external force impact. In addition, the user can further adjust the device by twisting the button handle 6338. The rotation of the button handle 6338 drives the second screw rod 6332 to rotate synchronously. Since the threads at both ends of the second screw rod 6332 rotate in opposite directions, the slider 6333 can be synchronously driven to reciprocate on the adjustment rail 6331 during the rotation process. The movement drives the coiling rack 6337 on the frame 6334 to realize reciprocating movement. By adjusting the coiling rack 6337 to move outward, the distance between the two coiling racks 6337 can be expanded; conversely, by adjusting the coiling racks 623 to be close to each other, the distance between the coiling racks 6337 can be reduced. During this adjustment process, the optical fiber will be further squeezed and stretched. The coiling rack 6337 drives the base block 6336 to slide inside the frame 6334, thereby squeezing the telescopic spring 6335. The telescopic spring 6335 continuously provides a stable elastic force to ensure that the optical fiber is always squeezed during the adjustment process, so that the optical fiber has better stability as a whole.

[0057] The independent setting of each adjustable winder 633 not only plays a certain anti-entanglement function, but also during use, these adjustable winders 633 themselves have good elasticity and can evenly apply elastic force to the optical fiber, so that the optical fiber is always in a taut state, thereby further reducing the probability of optical fiber entanglement. This series of design advantages can significantly improve the stability, processing quality and production efficiency of optical fiber production and processing.
