Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication technology, and in particular to a V-groove positioning device for high-precision optical fiber alignment. Background Technology

[0002] As a core component of fiber optic connection and coupling systems, the high-precision fiber alignment V-groove positioning device relies on precise geometric constraints to achieve accurate positioning and fixation of optical fibers. It plays a crucial role in fields such as optical communication, fiber optic sensing, and laser technology. Through the structural characteristics of the V-groove, it provides natural guidance and constraint for the optical fiber, ensuring that the optical fiber maintains a stable spatial attitude during docking or coupling. This provides a reliable physical basis for the efficient transmission of optical signals and is widely used in high-precision scenarios such as fiber optic array assembly, optical module packaging, and fiber optic connector manufacturing. In practical applications, high-precision fiber optic alignment V-groove positioning devices typically include the following core structures: 1. The V-groove substrate serves as a reference carrier for fiber positioning. Its surface is machined with V-grooves that are adapted to the shape of the fiber, and the initial alignment of the fiber is achieved through geometric contour constraints. 2. The pressure plate assembly securely clamps the optical fiber in the V-groove with controllable pressure to prevent displacement of the optical fiber during subsequent operation or use. 3. Positioning and guiding structure, used to ensure the relative positional accuracy between the V-groove substrate and other related components (such as fiber optic adapters and lens modules), and to ensure the consistency of the alignment reference of the entire system; 4. Cleaning auxiliary components are used to clean the inside of the V-groove before placing the optical fiber to remove contaminants that may affect positioning accuracy. Currently, an existing fiber optic alignment device for PLC optical splitters, disclosed in publication number (CN205992070U), includes: a base, one side of which is connected to a first fiber optic clamp, a second fiber optic clamp, and a third fiber optic clamp via a fixing rod; each of the first, second, and third fiber optic clamps is equipped with a slotted magnet, and slotted magnets are also provided on the top surface of the base at positions corresponding to the first, second, and third fiber optic clamps; a fiber optic positioning V-groove is provided at the center of the base, and inclined fiber optic position control consoles are provided on both sides of the fiber optic positioning V-groove, which control the fiber optic cable in the fiber optic positioning V-groove. This alignment device utilizes cold joining to introduce a point light source, resulting in high alignment precision, high efficiency, low loss, and convenient and simple operation. However, existing technologies still have significant limitations in the V-groove cleaning process. The cleaning process often involves manual hand-held tools (such as metal scrapers, brushes, or hard plastic sheets) to wipe the V-groove in one direction or back and forth. When using rigid tools, if the operator does not control the force properly, the tool edge can easily cause localized hard scratches against the groove wall, damaging the originally smooth, precision-machined surface. When scratches or roughening occur on the surface, the contact between the optical fiber and the groove wall becomes unstable. The optical fiber may experience slight misalignment due to the protrusions or depressions at the scratches, leading to a decrease in the alignment accuracy between the optical fibers, which in turn affects the stability and efficiency of optical signal transmission. This application addresses these problems by proposing a flexible cleaning solution. By designing a cleaning structure with flexible fitting characteristics, coupled with a stable guiding mechanism, damage to the groove surface can be avoided during V-groove cleaning, ensuring that the positioning reference accuracy of the V-groove remains unaffected after cleaning, providing a reliable guarantee for high-precision optical fiber alignment.

[0003] To address the shortcomings of existing technologies, this utility model provides a high-precision fiber optic alignment V-groove positioning device. This solves the problem that during the cleaning process, manual hand-held tools (such as metal scrapers, brushes, or hard plastic sheets) are often used to wipe the V-groove in one direction or back and forth. When using rigid tools, if the operator does not control the force properly, the edge of the tool can easily form a local hard scratch with the groove wall, damaging the original smooth precision-machined surface of the groove wall. When scratches or roughening occur on the surface, the contact state between the fiber optic cable and the groove wall becomes unstable.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A high-precision fiber optic alignment V-groove positioning device includes a base, two V-groove bodies are provided on the upper surface of the base, a set of pressure plates are rotatably connected to the upper surface of the base, a cleaning head is provided on the upper surface of the base, a cleaning strip is fixedly connected to the lower surface of the cleaning head, two guide strips are fixedly connected to the lower surface of the cleaning head, and a set of anti-slip grooves are formed on the surface of the cleaning head.

[0006] Preferably, the cleaning strip is used to clean the two V-shaped groove bodies, a rectangular groove is opened on the right surface of the base, the cleaning head is placed in the rectangular groove, and a protective plate is rotatably connected to the right surface of the base.

[0007] Compared with the prior art, the present invention has the following beneficial effects: The flexible fit of the cleaning strip overcomes the limitations of traditional rigid cleaning tools that cannot adapt to the complex contours of V-grooves. It achieves thorough cleaning of V-grooves without dead angles while avoiding damage to the groove surface, protecting its original geometric accuracy and surface finish.

[0011] This application provides a high-precision fiber optic V-groove positioning device, which effectively solves the problem that when cleaning V-grooves is done manually using handheld tools (such as metal scrapers, brushes, or hard plastic sheets) for unidirectional or reciprocating wiping, rigid tools can cause localized hard scratches when the hard material comes into contact with the groove wall. If the operator does not control the force properly, the tool edge can easily cause localized hard scratches on the groove wall, damaging the original smooth precision-machined surface. When scratches or roughening occur on the surface, the contact state between the fiber and the groove wall becomes unstable. By designing a cleaning structure with flexible fitting characteristics and a stable guiding mechanism, the device can clean the V-groove without dead angles while avoiding damage to the groove surface. This ensures that the positioning reference accuracy of the V-groove is not affected after cleaning, providing a reliable guarantee for high-precision fiber optic alignment.

[0012] Example like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application effectively solves the problem that during the cleaning process, manual hand-held tools (such as metal scrapers, brushes, or hard plastic sheets) are often used to wipe the V-groove in one direction or reciprocatingly. When using rigid tools, if the operator does not control the force properly, the edge of the tool can easily form local hard scratches with the groove wall, damaging the original smooth precision-machined surface of the groove wall. When scratches or roughening occur on the surface, the contact state between the optical fiber and the groove wall becomes unstable. The overall idea is as follows: To address the problems existing in the prior art, this utility model provides a high-precision fiber optic alignment V-groove positioning device, including a base 1, two V-groove bodies 2 disposed on the upper surface of the base 1, a set of pressure plates 3 rotatably connected to the upper surface of the base 1, a cleaning head 4 disposed on the upper surface of the base 1, a cleaning strip 10 fixedly connected to the lower surface of the cleaning head 4, two guide strips 9 fixedly connected to the lower surface of the cleaning head 4, and a set of anti-slip grooves 8 formed on the surface of the cleaning head 4. During operation, the cleaning head 4 is placed on the V-groove body 2, and by pressing the cleaning head 4, the cleaning strip 10 fixed on it forms a tight fit with the inner wall of the V-groove body 2, with the help of the cleaning... The flexible nature of the cleaning strip 10 allows it to fully fill the geometric space of the V-shaped groove body 2, ensuring complete coverage of the complex contours within the groove (including key areas such as the bottom and sidewalls). Subsequently, the cleaning head 4 moves laterally along the trajectory defined by the guide groove 5. During the relative movement, the cleaning strip 10 efficiently peels off and removes residual contaminants (such as fiber optic debris, matching fluid residue, and environmental dust) from the groove through physical adsorption and friction, completing the deep cleaning of the V-shaped groove body 2. After cleaning, the cleaning head 4 and the cleaning strip 10 are cleaned again. After cleaning, they are placed in the rectangular groove 6 for the next use.

[0013] Two guide grooves 5 are formed on the upper surface of the base 1, and two guide strips 9 are respectively attached to the two guide grooves 5. The cleaning strip 10 is made of silicone sponge and is used to clean the two V-groove bodies 2. A rectangular groove 6 is formed on the right surface of the base 1, and the cleaning head 4 is placed in the rectangular groove 6. A protective plate 7 is rotatably connected to the right surface of the base 1. The flexible fitting characteristics of the cleaning strip 10 break through the limitations of traditional rigid cleaning tools that are difficult to adapt to the complex contour of the V-groove. It can achieve cleaning without dead angles, greatly improve the thoroughness of cleaning, and ensure that the reference accuracy of the subsequent fiber positioning of the V-groove is not affected by contaminants. In addition, the flexible material of the cleaning strip 10 can effectively avoid scratching or wear on the precision machined surface of the V-groove, protect its original geometric accuracy and surface finish, and extend the service life of the V-groove. The cleaning strip 10 is made of silicone sponge. Silicone sponge has good elasticity, silicone material itself does not produce debris, and is wear-resistant, making it suitable for repeated use, especially suitable for removing the matching liquid residue attached to the groove.

[0014] Among them, base 1: as the basic load-bearing component of the device, it provides an installation platform for other components, ensures the stability of the overall structure, and is the basic support for the normal operation of the device; V-groove body 2: Provides a positioning reference for optical fibers, constrains the optical fibers through geometric contours to ensure that they maintain a stable posture during docking or coupling, and is the core structure for high-precision alignment; Pressure plate 3: Securely clamps the optical fiber in the V-groove with controllable pressure to prevent displacement during operation or use, ensuring stability after positioning and ensuring alignment accuracy; Cleaning head 4: It carries the cleaning strip 10 and guide strip 9, provides a carrier for cleaning operation, and drives the cleaning strip 10 to complete the cleaning by moving it. It is an operating component for efficient cleaning. Guide groove 5: It works with guide strip 9 to form a guide mechanism, which limits the movement trajectory of cleaning head 4, ensures stable movement during cleaning, avoids deviation, and improves cleaning consistency; Rectangular slot 6: Used to store cleaning head 4, making it convenient to store and retrieve, keeping cleaning head 4 and cleaning strip 10 clean, avoiding contamination, and ensuring the cleaning effect of the next cleaning; Protective plate 7: Protects the cleaning head 4 inside the rectangular groove 6, prevents external dust and impurities from contaminating it, maintains the cleanliness of the cleaning head 4 and the cleaning strip 10, and ensures cleaning reliability; Anti-slip groove 8: Increases the surface friction of the cleaning head 4, making it easier to hold and preventing slippage during operation, improving the stability and accuracy of the cleaning operation, and ensuring process controllability; Guide strip 9: It fits into the guide groove 5 to form a guiding fit, providing trajectory guidance for the movement of the cleaning head 4, ensuring that it moves along the preset path and ensuring thorough and uniform cleaning; Cleaning strip 10: Made of silicone sponge material, it flexibly conforms to the complex contour of the V-shaped groove body 2, achieving thorough cleaning without dead angles, avoiding scratches on the groove wall, protecting its precision and smoothness, and extending its service life.

[0015] Working principle: During operation, the cleaning head 4 is placed on the V-groove body 2. By pressing the cleaning head 4, the cleaning strip 10 fixed on it forms a tight fit with the inner wall of the V-groove body 2. Utilizing the flexibility of the cleaning strip 10, it can fully fill the geometric space of the V-groove body 2, ensuring complete coverage of the complex contours within the groove (including key areas such as the bottom and sidewalls). Subsequently, the cleaning head 4 is moved laterally along the trajectory defined by the guide groove 5. During this relative movement, the cleaning strip 10 efficiently peels off and removes residual contaminants (such as fiber optic debris, matching fluid residue, and environmental dust) through physical adsorption and friction, completing the deep cleaning of the V-groove body 2. After cleaning, the cleaning head 4 and cleaning strip 10 are then... After cleaning, place it in the rectangular groove 6 for next use. The flexible fit of the cleaning strip 10 overcomes the limitations of traditional rigid cleaning tools that are difficult to adapt to the complex contours of the V-groove, enabling thorough cleaning without dead angles and significantly improving the cleanliness. This ensures that the reference accuracy of the subsequent fiber positioning of the V-groove is not affected by contaminants. Furthermore, the flexible material of the cleaning strip 10 can effectively avoid scratching or abrasion on the precision-machined surface of the V-groove, protecting its original geometric accuracy and surface finish, and extending the service life of the V-groove. The cleaning strip 10 is made of silicone sponge, which has good elasticity, does not produce debris, and is wear-resistant, making it suitable for repeated use, especially for removing residual matching liquid adhering to the groove.
