Description

Technical Field

[0001] This utility model relates to the field of optical fiber processing technology, and specifically to a device for stripping the coating layer of optical fibers. Background Technology

[0002] When using optical fibers to manufacture related components, the first step is to remove the coating layer from the optical fiber. Currently, chemical stripping is generally used to remove the coating layer. This involves immersing the optical fiber in a mixed solvent containing chloroalkanes and ketones, using a chemical reaction to dissolve the resin coating layer. After the fiber is dissolved, it is placed in an ultrasonic oscillation tank containing alcohol for cleaning. After cleaning, the optical fiber is wiped clean with an alcohol cloth to ensure that there are no residues on the surface.

[0003] However, using chemical stripping has several drawbacks. First, the fiber optic cable used to remove the coating layer through corrosion and dissolution is fragile and prone to breakage. Second, the amount of mixed solvent and the dissolution time are difficult to control during the operation, resulting in poor reliability. Furthermore, the depth and width of the corroded cladding are uneven, making it difficult to improve efficiency and yield. Third, long-term use of chemical solutions poses risks to the environment and operator health, and the production cost is also high. Utility Model Content

[0004] The purpose of this invention is to provide a device for stripping the coating layer of optical fibers, which solves the problems of existing chemical stripping methods that easily damage optical fibers, pollute the environment, are inefficient, and have low reliability.

[0005] To achieve the purpose of this utility model, this utility model provides a device for stripping the coating layer of optical fibers, including a laser module, a moving module, and a rotating module. The laser module includes a first base and a laser. The moving module is located below the laser and includes a first slide, a second slide, and a mounting bracket. The first slide drives the mounting bracket to move along the x-axis, and the second slide drives the mounting bracket to move along the y-axis. The rotating module is disposed on the mounting bracket and includes a rotating drive component and an optical fiber clamping assembly. The rotating drive component drives the optical fiber clamping assembly to rotate. The optical fiber clamping assembly includes an optical fiber clamping tray and an optical fiber clamp. The optical fiber clamp is detachably mounted on the optical fiber clamping tray. The optical fiber clamping tray is provided with a first through hole. The optical fiber clamp includes a substrate, a clamping strip, and a pressure strip. The substrate is provided with a second through hole. The first through hole and the second through hole are correspondingly arranged. The clamping strip and the pressure strip are disposed on the same surface of the substrate and are located on opposite sides of the second through hole in the horizontal direction. The light-emitting surface of the laser faces the optical fiber clamp.

[0006] As can be seen from the above scheme, the fiber optic clamp is equipped with a clamping strip and a pressure strip. The clamping strip is located on one side of the second through hole to clamp the fiber, and the pressure strip is located on the other side of the second through hole. The fiber passes through the gap between the pressure strip and the substrate to be fixed. The clamping strip and the pressure strip work together to keep the fiber taut, preventing displacement during subsequent movement and rotation, which would affect the stripping effect. The fiber optic clamp is then fixed to the fiber optic clamp support plate. By moving the mounting bracket along the x and y axes, the position of the fiber where the coating needs to be stripped can be moved to directly below the laser. The laser can then output laser light to the fiber, using the laser to strip the coating. This is a non-disconnect method. The contact-type design allows for more precise stripping, and the simple operation requires only controlling the movement of the mounting bracket. It offers higher efficiency, higher reliability, and prevents damage to the optical fiber or environmental pollution. Furthermore, the fiber coating stripping device includes a rotating module. Both the fiber clamp tray and the fiber clamp are equipped with through holes. The fiber is fixed at the position corresponding to the through hole, and rotation allows for 360° stripping of the coating, making the process more convenient and faster. The fiber clamp tray and clamp are detachable, allowing for clamp replacement to accommodate different sizes and types of optical fibers, broadening its application range and meeting production requirements.

[0007] A further option is to mount the clamping bar on the fiber optic clamp via a pivot, and the clamping bar can rotate around the pivot, with a gripping part provided on the clamping bar.

[0008] As can be seen from the above scheme, the staff can increase the gap between the clamping bar and the substrate by lifting the holding part upward, which makes it easier to place the optical fiber; after releasing the holding part, the clamping bar can effectively clamp the optical fiber by pressing down.

[0009] A further option is to provide at least one limiting groove on the substrate, with the limiting groove located below the clamping strip.

[0010] As can be seen from the above scheme, one end of the optical fiber is fixed in the limiting groove. The pressure strip and the limiting groove clamp the optical fiber to achieve optical fiber fixation. At the same time, the limiting groove can be used to fix the crystal product carried by the optical fiber head to prevent the product from being damaged during the rotation to remove the coating. The substrate is provided with multiple limiting grooves, which can realize batch operation and improve production efficiency. In addition, the multiple limiting grooves are arranged in parallel, and multiple optical fibers can also be fixed in parallel. When the coating is removed later, the multiple optical fibers will not affect each other.

[0011] A further embodiment involves a fiber coiling position on the substrate, with positioning posts on both horizontal sides of the fiber coiling position, and an elastic strip between the two positioning posts to form the fiber coiling position. Preferably, the elastic strip, clamping strip, and pressure strip are arranged parallel to each other in the same direction.

[0012] As can be seen from the above scheme, an elastic strip is set between the two positioning posts to form a fiber coil position. The optical fiber of the coil is pressed under the elastic strip, which not only provides a good fixing effect for the optical fiber, but also makes it less likely to cause damage to the optical fiber.

[0013] A further solution is to install a first protective pad under the pressure strip and a second protective pad under the clamping strip.

[0014] As can be seen from the above scheme, both the first and second protective pads are elastic, which can effectively prevent the pressure strip and clamping strip from exerting excessive force on the optical fiber and damaging it.

[0015] A further embodiment is that the fiber optic clamp tray is provided with a clamp limiting block; the fiber optic clamp also includes a first magnetic block, and the fiber optic clamp tray includes a second magnetic block, with the first magnetic block and the second magnetic block attracting each other.

[0016] As can be seen from the above solutions, the magnetic attraction prevents the clamp from falling off during rotation, making the operation simple and convenient; the fiber optic limit block further prevents the fiber optic clamp from falling off during rotation.

[0017] A further option is to have a slide rail on the first base, with the laser mounted on the slide rail, and the laser can move along the slide rail in the z-axis direction.

[0018] As can be seen from the above scheme, the laser can move along the z-axis, thereby adjusting the focal height of the laser, which can more accurately remove the coating of the optical fiber without damaging the optical fiber.

[0019] A further option is that the rotation module also includes a rotation seat, which is connected to the fiber optic clamp tray, and the rotation drive component drives the rotation seat to rotate.

[0020] As can be seen from the above scheme, the rotating seat ensures the stability and accuracy of the fiber optic clamp tray during rotation; the fiber optic clamp can fix single or multiple fibers, achieving multi-angle rotation of 360°, 180° and 120°. The fiber to be stripped can remain concentric or parallel to the axis of rotation of the rotating seat during rotation, ensuring that the depth and width of stripping can be uniformly distributed, thereby improving production efficiency and yield.

[0021] A further solution is to install a position detection sensor on the mounting bracket and a sensing plate on the rotating base.

[0022] As can be seen from the above scheme, by setting up sensors, the specific position and status of the fiber optic clamp tray can be detected, allowing for more precise rotation at different angles and more accurate fiber stripping and repositioning.

[0023] A further embodiment includes an optical fiber coating removal device that also includes an operation control system and a display screen. The display screen is fixedly mounted on the first base via a display screen bracket. The operation control system is electrically connected to the display screen, the rotation module, the laser module, and the movement module. The optical fiber coating removal device also includes an operating platform and a second base. Both the first base and the second base are mounted on the operating platform, and both the movement module and the rotation module are mounted on the second base.

[0024] As can be seen from the above scheme, by setting up an operation control system and a display screen, the operating status of the device can be monitored and the automatic rotation to remove the coating can be achieved, thus achieving the effect of removing the fiber coating with high efficiency and high precision, ensuring that the fiber is not damaged. The setting of the operating table realizes functional integration and space optimization. As the core support, the operating table provides a stable platform for all components, enabling the entire device to maintain a high degree of coordination and smoothness when stripping the fiber coating, bringing users a more convenient and efficient user experience.

The second slide 43 includes a third driving component 431, which drives the mounting bracket 44 to move along the second slide 43 in the y-axis direction. In this embodiment, both the second driving component 421 and the third driving component 431 are motors. Both the first driving component 421 and the second driving component 431 are electrically connected to the operation control system. The x-axis, y-axis, and z-axis directions are mutually perpendicular.

[0038] The rotation module is mounted on the mounting bracket 44 and includes a rotation drive component 451, a rotation seat 452, and an optical fiber clamping assembly. In this embodiment, the optical fiber clamping assembly includes an optical fiber clamping plate 453 and an optical fiber clamp 5. The rotation seat 452 is connected to the optical fiber clamping plate 453. The rotation drive component 451 drives the rotation seat 452 to rotate, thereby causing the optical fiber clamping plate 453 to rotate. In this embodiment, the rotation drive component 451 is a motor. The rotation drive component 451 is electrically connected to the operation control system.

[0039] A position detection sensor 455 is mounted on the mounting bracket 44, and a sensing plate 456 is mounted on the rotating base 452. The position detection sensor 455 is electrically connected to the operation control system.

[0040] The fiber optic clamp tray 453 is provided with a first through hole 457 and a second magnetic block (not shown in the figure). The fiber optic clamp tray 453 is provided with a detachable fiber optic clamp 5. The fiber optic clamp tray 453 is provided with a clamp limiting block 457, which is used to prevent the fiber optic clamp 5 from falling off during rotation.

[0041] See Figure 4 , Figure 7 and Figure 8 The fiber optic clamp 5 includes a substrate 53, a clamping strip 513, and a pressure strip 511. In this embodiment, the clamping strip 513 and the pressure strip 511 are arranged parallel to each other on the same surface of the substrate 53 along the x-axis. A second through hole 52 is provided on the substrate 53, and a first through hole 454 is correspondingly provided with the second through hole 52. The clamping strip 513 and the pressure strip 511 are located on opposite sides of the second through hole 52 along the x-axis. The substrate 53 also has a fiber coiling position, and positioning posts 5122 are respectively provided on both sides of the fiber coiling position along the y-axis. An elastic strip 5121 is provided between the two positioning posts 5122 to form the fiber coiling position. In this embodiment, it includes two sets of positioning posts 5122 and two elastic strips 5121. The two elastic strips 5121 are arranged parallel to the pressure strip 511 and the clamping strip 513 along the x-axis, and the elastic strips 5121 and the pressure strip 511 are located on the same side of the second through hole 52. The clamping bar 513 is mounted on the fiber optic clamp 5 via a pivot, and the clamping bar 513 can rotate around the pivot (not shown in the figure). The clamping bar 513 is provided with a gripping portion 5131. At least one limiting groove 514 is provided on the substrate 53, and the limiting groove 514 is located below the clamping bar 513. The limiting groove 514 is preferably a V-shaped groove. The number of limiting grooves 514 depends on the number of optical fibers to be clamped. A gap is formed between the pressure bar 511 and the substrate 53 for the optical fiber to pass through. Preferably, in this embodiment, a first protective pad 515 is provided below the pressure bar 511, a third protective pad 517 is provided on the substrate near the elastic strip 5121 of the pressure bar 511, and a second protective pad 516 is provided below the clamping bar 513.

The protective pad protects the optical fiber, preventing excessive force from the clamping strip 511 and holding strip 513 that could damage the optical fiber and prevent it from moving, thus affecting the subsequent coating removal operation.

[0042] The display screen 3 is fixedly mounted on the first base 22 via the display screen bracket 31. The display screen 3 is electrically connected to the operation control system. Both the first base 22 and the second base 41 are mounted on the operating console 1.

[0043] The fiber optic coating removal device of this embodiment includes a fiber optic clamp 5 with a clamping bar 513, a limiting groove 514, a pressure bar 511, and a fiber coiling position. The clamping bar 513 clamps the fiber, the limiting groove 514 and the pressure bar 511 further fix the fiber, and the fiber coiling position is formed by a fixed elastic bar 5121. The coiled fiber is pressed under the elastic bar 5121. The fiber is fixed in three ways, so that the fiber is in a fixed and taut state. The fiber optic clamp 5 is then placed on the fiber optic clamp support plate 453, so that the fiber to be stripped of the coating is coaxial or parallel to the axis of the rotating seat 452. The first driving component 231, the second driving component 421 and the third driving component 431 are driven by the operation display screen 3 to align the laser 21 with the position of the fiber to be stripped, and the laser 21 is adjusted to a suitable focal height. Then, it is rotated in conjunction with the rotating module to remove the coating of the fiber using the laser. The fiber optic clamp 5 can hold multiple optical fibers and achieve synchronous 360° and 180° rotation. If the fiber optic clamp 5 holds a single optical fiber, it can also achieve multiple 120° rotations.

[0044] When multiple optical fibers are fixed in the optical fiber clamp 5, the coating layer can be removed by moving each fiber one by one under the laser through the moving module, or only any one fiber in the batch can be removed, thereby achieving fully automatic, efficient and precise laser removal of the optical fiber coating layer.

[0045] The rotation module is equipped with a position detection sensor 455 and a sensing plate 456 to detect the position of the fiber optic clamp tray 453. After receiving the information from the position detection sensor 455, the operation control system can rotate according to the set angle. Once the angle is reached, the laser 21 emits a laser of the corresponding wavelength to remove the coating layer of the fiber.

[0046] The fiber coating removal device of this embodiment removes the fiber coating using laser light. This non-contact method avoids mechanical damage to the fiber, prevents environmental pollution, reduces production costs, and improves efficiency and yield. Furthermore, the device can automatically position and rotate the fiber to change the working surface. During rotation, it automatically reads and collects laser emission information. When the system automatically reads the set data for the laser, it controls the laser to emit light to remove the coating. The device is also compatible with different fiber specifications, and loading and unloading operations are simple. In actual use, the device's accuracy deviation is within 0.03mm, with a front-to-back accuracy error of <0.1mm, a vertical accuracy error of <0.3mm, a front-to-back height error of <0.2mm, and a rotation angle accuracy of <0.05°.
