Description

Technical Field

[0001] This utility model belongs to the field of optical fiber production tooling fixtures, and particularly relates to an optical fiber array fixture and coating assembly. Background Technology

[0002] Vacuum coating refers to coating in a high vacuum environment (approximately 6 × 10⁻⁶). -4 Up to 8×10 -4 A technique that involves evaporating solid materials such as metals at a pressure of 400°C (Pa) to vaporize them and deposit them onto the surface of a product. Coating the surface of an object offers numerous advantages, not only providing decorative effects but also altering its structural properties, such as improving optical properties, electrical conductivity, insulation, and thermal conductivity.

[0003] Generally, there are two methods for vacuum coating: thermal evaporation and magnetron sputtering. The principle of thermal evaporation coating is to evaporate a solid in a vacuum environment, converting it into a gaseous state, which is then deposited onto the surface of the product being coated. Magnetron sputtering coating utilizes magnetic and electric fields to sputter a target material onto the surface of the object being coated, forming a film layer.

[0004] Vacuum coating equipment can generally only perform on-chip coating or fiber side coating. Due to the size of optical fibers and the difficulty in fixing them, fiber clamps are usually required to fix the fibers and thus achieve direct coating on the fiber end face.

[0005] In related technologies, fiber optic clamps typically consist of fastening elements and mounting plates mounted on coating trays. Fixing holes with internal threads are drilled in the mounting plate, and bolts or screws are used as the fastening elements to connect the fastening elements and the mounting plate. The end of the fiber furthest from the fiber end face is then fixed to the fastening element. While this achieves relative fixation between the fiber and the coating tray, this setup only ensures a stable connection between one end of the fiber and the fastening element. The rest of the fiber stands directly above the fastening element, making the fixation less precise and secure. This can lead to fiber tilting or shifting during coating, resulting in uneven coating. Utility Model Content

[0006] The technical objective of this utility model is to provide a fiber optic array clamp, which aims to solve the technical problem in related technologies where the fiber optic clamp does not fix the fiber optic cable precisely and firmly enough, and the fiber optic cable is prone to tilting or shifting during the coating process, which easily leads to uneven coating.

[0008] Further, in some embodiments, the abutment groove includes a first sub-abutment groove and a second sub-abutment groove arranged sequentially along the axial direction and communicating with each other; and the projection surface of the first sub-abutment groove along the axial direction covers the second sub-abutment groove; the first sub-abutment groove is used to abut the optical fiber body, the second sub-abutment groove is used to abut the optical fiber core, and the end face of the optical fiber protrudes from the end of the second sub-abutment groove away from the first sub-abutment groove; along the radial direction, the second cover covers the second sub-abutment groove and covers at least a portion of the first sub-abutment groove.

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] Please see Figures 1 to 5 This utility model provides an optical fiber array clamp, including a connecting bracket and a connector 1; the connector 1 includes a first cover 11 and a second cover 12; the first cover 11 is connected to the outer periphery of the connecting bracket, and the second cover 12 is connected to the side of the first cover 11 that is radially away from the connecting bracket; and the first cover 11 has an axially extending abutting groove 111 with its opening facing the second cover 12, the abutting groove 111 is used to abut the optical fiber, the optical fiber is clamped between the abutting groove 111 and the second cover 12; the end face of the optical fiber is exposed to the outside through the abutting groove 111.

[0036] In this embodiment of the invention, the clamp includes a connecting bracket and a connector 1. A first cover 11 of the connector 1 is connected to the outer periphery of the connecting bracket, and a second cover 12 is connected to the side of the first cover 11 radially away from the connecting bracket. A support groove 111 is also provided on the side of the first cover 11 radially away from the connecting bracket. The support groove 111 extends axially and can be used to fit the optical fiber, allowing the support groove 111 to support and hold the optical fiber. The second cover 12 is then closed and connected to the first cover 11. This allows the optical fiber to be stably clamped between the support groove 111 and the second cover 12. Furthermore, the optical fiber end face is exposed to the outside through the support groove 111, allowing for operations such as coating on the optical fiber end face. In other words, this utility model embodiment can achieve precise fixation of optical fiber by providing an axially extending support groove 111 in the first cover 11 and a second cover 12 that covers and connects to the first cover 11, thereby avoiding the situation where the optical fiber is tilted or deviated during the coating process and ensuring the uniformity of the film layer on the end face of the optical fiber.

[0037] It should be noted that the fixture in this embodiment of the invention can be used not only for coating but also for processing the end face of optical fibers or fixing optical fibers. For example, in some embodiments, the fixture can be used for two-photon processing. In some embodiments, the fixture can be used for aligning and coupling optical fibers to ensure efficient transmission of optical signals.

[0038] Further, in some embodiments, the abutment groove 111 includes a first sub-abutment groove 1111 and a second sub-abutment groove 1112 that are sequentially arranged along the axial direction and interconnected with each other; and the projection surface of the first sub-abutment groove 1111 along the axial direction covers the second sub-abutment groove 1112; the first sub-abutment groove 1111 is used to abut the optical fiber body, the second sub-abutment groove 1112 is used to abut the optical fiber core, and the end face of the optical fiber protrudes from the end of the second sub-abutment groove 1112 away from the first sub-abutment groove 1111; along the radial direction, the second cover 12 covers the second sub-abutment groove 1112 and covers at least part of the first sub-abutment groove 1111.

[0039] Specifically, an optical fiber typically includes an optical fiber body, an optical fiber core, and an optical fiber end face. Since the diameter of the optical fiber body is larger than that of the optical fiber core, the axial dimension of the first sub-support groove 1111 can be larger than the axial dimension of the second sub-support groove 1112. Furthermore, the optical fiber body includes a cylindrical portion and a tapered portion connected to one end of the optical fiber core. Therefore, the portion of the first sub-support groove 1111 that is away from the second sub-support groove 1112 has the same axial dimension. The other portion of the first sub-support groove 1111 that connects to the second sub-support groove 1112 has an axial dimension extending from the first sub-support groove 1111 to the second sub-support groove 1112. The direction of the abutment groove 1112 gradually narrows; in addition, the fiber core is a cylindrical body with a diameter smaller than that of the fiber body. In this way, the second sub-abutment groove 1112 can be set with a uniform diameter along the axial direction and a size smaller than that of the first sub-abutment groove 1111. This setting makes the shape of the abutment groove 111 match the shape of the fiber, thereby better supporting and holding the fiber; then, by covering and connecting the second cover 12 to the first cover 11, the fiber can be accurately and firmly placed between the abutment groove 111 and the second cover 12, which can effectively prevent the fiber from shifting. In addition, the second cover 12 completely covers the second sub-support groove 1112 radially, which can ensure the clamping effect on the fiber core and thus avoid the fiber end face from shifting. The second cover 12 can partially or completely cover the first sub-support groove 1111 radially. The fiber body is a certain distance away from the fiber end face. Therefore, even if the fiber body is not completely clamped, it will not affect the stability of the fiber end face. This can reduce the material of the second cover 12 and lower the material cost while ensuring the stability of the fiber end face connection.

[0040] Furthermore, in some embodiments, the first cover 11 protrudes radially toward the second cover 12 with an abutment portion 112, the abutment portion 112 being disposed at one end of the second sub-support groove 1112 axially away from the first sub-support groove 1111; the abutment portion 112 has a relief groove 1121 communicating with the second sub-support groove 1112, the optical fiber end face protruding from the relief groove 1121 axially away from the second sub-support groove 1112; and one axial end of the second cover 12 abuts against one axial side of the abutment portion 112.

[0041] Specifically, the surface of the first cover 11 facing the second cover 12 has a support groove 111, and a contact portion 112 protrudes radially on the surface. At the same time, the contact portion 112 has a relief groove 1121, and the bottom of the relief groove 1121 is connected to the bottom of the second sub-support groove 1112, so that the optical fiber can extend directly from the second sub-support groove 1112 to the relief groove 1121 and then protrude from the relief groove 1121 to the side away from the second sub-support groove 1112. In addition, along the axial direction, the first sub-support groove 1111 is at the bottom and the clearance groove 1121 is at the top; the fiber end face is located at the top of the fiber core, and the top of the second cover 12 abuts against the bottom side of the abutment portion 112. In this way, the upper part of the fiber core can fit against the clearance groove 1121 and be supported by the second cover 12, so that the fiber can be more stable in the clamp; at the same time, the positioning connection of the first cover 11 and the second cover 12 can also be realized.

[0042] Furthermore, in some embodiments, the second cover 12 is provided with an axially extending flexible member on the side facing the first cover 11, and the optical fiber is clamped between the flexible member and the abutment groove 111.

[0043] Specifically, the second cover 12 has a closing groove 121 that opens towards the first cover 11 and extends axially. A flexible element is provided inside the closing groove 121. Thus, when the second cover 12 is closed to connect with the first cover 11, the optical fiber can be clamped between the flexible element and the holding groove 121. The flexible element acts on the optical fiber, increasing the clamping force and making the clamping force more uniform, thus better clamping the optical fiber and avoiding the risk of displacement and tilting during coating. Simultaneously, the flexible element also protects the optical fiber. In other words, this embodiment of the invention, through the cooperation of various groove types and flexible elements, enhances the connection stability of the optical fiber and also protects the optical fiber.

[0044] For example, the flexible component can be a structural component with elasticity, such as rubber or silicone.

[0045] Furthermore, in some embodiments, the connecting bracket is provided with a plurality of connectors 1 at circumferential intervals.

[0046] Specifically, multiple connectors 1 can be arranged at intervals along the circumference on the outer periphery of the connecting bracket, and each connector 1 can clamp one optical fiber. By arranging multiple connectors 1, multiple optical fibers can be clamped simultaneously by one clamp, achieving an array distribution. This allows for simultaneous array coating processing of multiple optical fibers, meaning that coating can be performed on the end faces of several optical fibers at once. This is simple, convenient, time-saving, expands the application of the clamp, and improves its practicality.

[0047] Understandably, the number of connectors 1 can be determined based on the dimensions of the outer periphery of the connecting bracket and the dimensions of connectors 1, and can be set according to actual conditions. For example, the number of connectors 1 can be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, etc.

[0048] Furthermore, in some embodiments, a first magnetic attractor is provided on the outer periphery of the connecting bracket, and a second magnetic attractor is provided on the connector 1, with the first magnetic attractor and the second magnetic attractor being magnetically connected.

[0049] Specifically, a plurality of first magnetic suction holes 33 with openings along the axial direction are provided on the outer periphery of the connecting bracket. When the fixture is assembled with the coating instrument, the openings of the first magnetic suction holes 33 face the bottom of the coating instrument, allowing the first magnetic suction components to be assembled into the first magnetic suction holes 33, with each first magnetic suction component corresponding to one of the first magnetic suction holes 33. Similarly, a second magnetic suction hole 13 is provided on the connecting member 1, with the opening of the second magnetic suction hole 13 facing the bottom of the coating instrument, allowing the second magnetic suction components to be assembled into the second magnetic suction hole 13, with each second magnetic suction component corresponding to one of the second magnetic suction holes 13. In this way, the magnetic connection between the connecting bracket and the connecting member 1 can be achieved through the magnetic connection of the first and second magnetic suction components, making the operation simple and quick.

[0050] For example, the first magnetic attractor and the second magnetic attractor can be magnets.

[0051] Furthermore, in some embodiments, the connecting bracket is provided with a first positioning structure, and the connector 1 is provided with a second positioning structure, with the first positioning structure connected to the second positioning structure. Through the positioning connection of the first and second positioning structures, the connecting bracket and connector 1 can be initially positioned. Then, through the magnetic connection of the first and second magnetic components, a stable connection between the connecting bracket and connector 1 is achieved.

[0052] For example, the first positioning structure can be a T-shaped protrusion 31 protruding from the outer periphery of the connecting bracket, and the second positioning structure can be a T-shaped groove 113 opened on the side of the first cover 11 away from the second cover 12. By inserting the T-shaped protrusion 31 into the T-shaped groove 113, the initial positioning connection between the connecting bracket and the connecting piece 1 can be achieved, preventing positional deviation between the connecting piece 1 and the connecting bracket, avoiding unstable clamping of the optical fiber, and the structure is simple and the operation is quick.

[0053] In some specific embodiments, both the first cover 11 and the second cover 12 are provided with a plurality of second magnetic holes 13, and the second magnetic components are assembled into the second magnetic holes 13. In this way, the second magnetic components of the first cover 11 and the second magnetic components of the second cover 12 can be magnetically connected, thereby realizing the magnetic connection between the first cover 11 and the second cover 12, which is simple and quick to operate.

[0054] Furthermore, a positioning structure is also provided between the first cover 11 and the second cover 12. The positioning structure can achieve the initial positioning of the first cover 11 and the second cover 12. Then, the first cover 11 and the second cover 12 can be magnetically connected to achieve a stable connection.

[0055] In some specific embodiments, the abutting portion 112 of the first cover 11 can serve as the positioning structure of the first cover 11, and one side of the second cover 12 along the axial direction can serve as the positioning structure of the second cover 12 along the axial direction. By abutting the abutting portion 112 of the first cover 11 and the second cover 12 abutting against each other along the axial direction, the initial positioning of the first cover 11 and the second cover 12 can be achieved. The structure is simple and the operation is quick.

[0056] Furthermore, it is understandable that since the first cover 11 is closer to the connecting bracket, the first magnetic member of the connecting bracket and the second magnetic member of the first cover 11 are essentially magnetically connected to achieve a fixed connection between the connecting members and the connecting member 1.

[0057] Furthermore, in some specific embodiments, the T-shaped groove 113 and the T-shaped protrusion 31 can be aligned first to fix the first cover 11 and the connecting bracket. Then, the optical fiber is held against the holding groove 111 and the clearance groove 1121 of the first cover 11, while one axial end of the second cover 12 is abutted against the abutting part 112 of the first cover 11, thus fixing the first cover 11 and the second cover 12 together. This allows the optical fiber to be clamped between the holding groove 111 and the second cover 12, completing the clamping of the optical fiber and exposing the end face of the optical fiber to the outside, so that the end face of the optical fiber can be coated. When disassembly is required, simply overcome the magnetic attraction, remove the second cover 12 from the first cover 11, remove the optical fiber, and then remove the first cover 11 from the connecting bracket. The entire installation and disassembly process is very quick and convenient, and can achieve precise fixation of the optical fiber, ensuring the uniformity of the optical fiber coating.

[0058] In other embodiments, the connecting bracket and connector 1 can be integrally injection molded. In this way, the end face of the optical fiber can be directly pulled along the axial direction from the end of the supporting groove 111 away from the relief groove 1121 to protrude from the relief groove 1121, which can also achieve the clamping of the optical fiber.

[0059] In other embodiments, the connecting bracket and connector 1 can also be detachable connections such as screw connections. This also provides the advantages of convenient assembly and disassembly, ensuring uniformity of fiber coating.

[0060] Furthermore, in some embodiments, the connecting bracket includes a support base 2 and a base 3; the support base 2 includes a seat body 21 and a support column 22 connected to the seat body 21; the base 3 has a receiving cavity 32, and the base 3 also has a connecting hole 34 communicating with the receiving cavity 32; the support column 22 is disposed in the receiving cavity 32 and one end of the seat body 21 away from the seat body 21 along the axial direction passes through the connecting hole 34; the connector 1 is disposed on the outer periphery of the base 3, and the tail of the optical fiber protrudes out of the abutment groove 111 and is wound around the support column 22 to be received in the receiving cavity 32.

[0061] Specifically, the connecting bracket can be divided into a support base 2 and a base 3. The support base 2 can support the entire clamp and support the base 3 and the connector 1. The base 3 can include an annular portion and a cover portion connected to one axial end of the annular portion. Along the axial direction, with the first sub-support groove 1111 below and the first sub-support groove 1111 above, the cover portion is disposed on the top side of the annular portion. The connector 1 can be disposed on the outer periphery of the annular portion. A receiving cavity 32 is defined between the annular portion and the cover portion, and the opening of the receiving cavity 32 faces downward. The cover portion has a connecting hole 34. The seat body 21 of the support base 2 is used as a supporting structure. The support column 22 of the support base 2 passes through the connecting hole 34 to realize the fixed connection between the support base 2 and the base 3. In addition, along the axial direction from bottom to top, the optical fiber sequentially includes an optical fiber tail, an optical fiber body, an optical fiber core, and an optical fiber end face. The optical fiber body is held between the first sub-support groove 1111 and the second cover 12, the optical fiber core is held between the second sub-support groove 1112 and the second cover 12, the optical fiber end face protrudes from the clearance groove 1121, and the optical fiber tail protrudes below the first sub-support groove 1111 and can be bent into the receiving cavity 32 and then wound around the support post 22. This allows the optical fiber tail to be received in the receiving cavity 32, which can prevent the optical fiber tail from being exposed to the vacuum cavity of the coating instrument and prevent the optical fiber tail from being coated.

[0062] Furthermore, in some embodiments, along the axial direction, with the first sub-support groove 1111 at the bottom and the first sub-support groove 1111 at the top, the support column 22 of the support base 2 is reduced from bottom to top. This makes the support column 22 smaller so that it can pass through the connection hole 34 of the base 3. At the same time, it can also increase the weight of the support column 22 and improve the overall structural strength of the support base 2, so that the support base 2 is sufficient to support the base 3 and the connector 1.

[0063] Furthermore, in some embodiments, along the axial direction, with the first sub-support groove 1111 as the lower part and the first sub-support groove 1111 as the upper part, a support ring is also fixedly connected to the outside of the support column 22. The support ring is disposed below the base 2 so that the support ring can better support the base 2.

[0064] In some specific embodiments, the first magnetic suction hole 33 is formed in the annular portion of the base 3, and the first magnetic suction member is assembled in the first magnetic suction hole 33, so that the base 3 and the first cover 11 can be fixedly connected by the magnetic attraction of the first magnetic suction member and the second magnetic suction member. Furthermore, since the support column 22 of the support base 2 passes through the connection hole 34 of the cover portion of the base 3, i.e., the support base 2 and the base 3 are fixedly connected, the first cover 11 and the connecting bracket can be fixedly connected, thereby achieving the fixed connection between the connecting member 1 and the connecting bracket, simplifying the use of the clamp and making the operation simple and quick.

[0065] In some specific embodiments, the first positioning structure can be a T-shaped protrusion 31 protruding from the outer periphery of the annular portion of the base 3, and the second positioning structure can be a T-shaped groove 113 opened on the side of the first cover 11 away from the second cover 12. By inserting the T-shaped protrusion 31 into the T-shaped groove 113, the initial positioning connection between the base 3 and the connector 1 can be achieved, thereby preventing positional deviation between the connector 1 and the connecting bracket, avoiding unstable clamping of the optical fiber, and the structure is simple and the operation is quick.

[0066] Furthermore, in some embodiments, the connecting bracket is also provided with a gripping portion.

[0067] For example, the gripping part can be connected to the support post 22 and / or to the side of the connection hole 34. In this way, the coating process of the fiber end face can be carried out without hindering it, and the entire fixture can be easily removed from the vacuum chamber of the coating machine after the coating is completed.

[0068] For example, the grip portion can be a handle.

[0069] Furthermore, in some embodiments, a coating assembly includes a coating instrument and a fiber array fixture. The coating instrument has a vacuum chamber and a coating disk disposed in the vacuum chamber. The coating disk is rotatably connected to the vacuum chamber, and the fiber array fixture is fixedly assembled to the coating disk.

[0070] Specifically, the coating apparatus has a vacuum chamber containing a rotatable coating disk. The entire fixture can be placed on the coating disk, with the support body 21 of the support pedestal 2 resting on it, ensuring the fiber end face is vertically upward. During coating, target atoms bombarded by argon ions within the vacuum chamber deposit onto the fiber end face, forming a film. Because the coating disk can rotate the entire fixture, a uniform film can be formed on each fiber end face. Furthermore, the coating apparatus can control the coating time, thereby controlling the film thickness on the fiber end face.

[0071] Furthermore, in some embodiments, the fixture can be manufactured using 3D printing. The use of 3D printing technology can reduce costs, facilitate mass production, and lower the batch processing costs of the fixture. Additionally, in some embodiments, the annular portion of the base 3 can be circular.
