Description

Technical Field

[0001] This utility model relates to the field of optical fiber alignment technology, and more specifically, it relates to an alignment device for optical fiber splicing. Background Technology

[0002] Optical fiber is a thin optical medium that uses high-purity quartz glass or special polymers as its core material to efficiently transmit optical signals. Its structure usually consists of a central core, a cladding layer that surrounds the core, and an outer coating layer. Its diameter is mostly in the range of micrometers to millimeters. Optical fibers are widely used in optical fiber communication, optical fiber sensing, medical equipment, laser processing and other fields, and are a key basic component of modern information society and high-end manufacturing industry.

[0003] Currently, optical fibers are susceptible to slight displacement due to vibration, impact, or temperature changes during use. By applying adhesive and allowing it to cure to form a rigid or flexible support structure, the optical fiber can be precisely fixed in a preset position, avoiding core alignment deviations caused by positional offsets, thereby preventing increased optical power loss or polarization state disorder. Before the optical fiber adhesive is applied and cured, it needs to be spliced. The most important step in the splicing process is the alignment of the optical fiber with its axis.

[0004] However, during the alignment process of fiber bundles, fiber alignment is required after fiber laying. However, after fiber laying, the fiber is scattered over a large area. If fiber alignment is performed directly, it is difficult for operators to operate and the fiber alignment efficiency is low. Therefore, an alignment device for fiber splicing is proposed to improve the existing problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fiber optic coupling device.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A fiber optic coupling device includes an imaging component, on one side of which are sequentially arranged a ferrule component, a limiting component, a fiber optic arranging component, and a fiber optic rotator.

[0008] The ferrule assembly includes a ferrule slot, which has a plurality of V-shaped grooves, and an optical fiber is disposed inside the V-shaped grooves.

[0009] The limiting component includes a first limiting block, and a second limiting block is provided on one side of the first limiting block. The first limiting block and the second limiting block are arranged in an inverted V shape.

[0010] The present invention is further configured such that: the ferrule assembly also includes a worktable, the top of the worktable is provided with a slide rail, an adjusting rod is provided through the slide rail, the ferrule slot is connected to the adjusting rod by a thread, and the ferrule slot is slidably connected to the slide rail.

[0012] The present invention is further configured such that: a mounting bracket is provided on one side of the limiting seat, the mounting bracket is L-shaped, a fixing rod is provided through the mounting bracket, and the fixing rod is connected to the mounting bracket by a thread.

[0013] The present invention is further configured such that: the limiting component also includes a base, and a sliding track is provided on one side of the base, the sliding track and the base being integrally formed.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0031] Please see Figures 1-5 The present invention provides the following technical solution:

[0032] Example 1, see Figure 1 A fiber optic coupling device includes an imaging component 1, on one side of which are sequentially arranged a ferrule component 2, a limiting component 3, a fiber optic arranging component 4, and a fiber optic rotator 5.

[0033] The imaging component 1 includes an imaging unit and an image acquisition unit. The image acquisition unit is used to align with the end face of the optical fiber, acquire the image information of the optical fiber, and perform imaging through the imaging unit. The imaging unit is connected to an external display device, and the imaging results can be displayed on the display device. The imaging results provide a basis for the rotation adjustment of the optical fiber rotator 5 and help determine the position and angle of the optical fiber.

[0034] The fiber bundle can be placed through the ferrule assembly 2. The ferrule assembly 2 is set opposite to the imaging assembly 1, which facilitates the imaging assembly 1 to collect images of the end face of the fiber.

[0035] The fiber arrangement assembly 4 includes a fiber arrangement plate and a fiber arrangement slot. The optical fiber placed after the ferrule assembly 2 can be arranged in the fiber arrangement slot.

[0036] The fiber optic rotator 5 includes a fiber optic placement seat and a fiber optic regulator. After the fiber optic cable is arranged by the fiber optic cable assembly 4, the fiber optic cable is placed in the position of the fiber optic placement seat. After the fiber optic cable is placed, the angle and position of the fiber optic cable can be adjusted by rotating the fiber optic regulator.

[0037] Since the fiber bundle will be scattered between the ferrule assembly 2 and the fiber arrangement assembly 4 after being placed at the ferrule assembly 2, the limiting assembly 3 is used to limit the fiber bundle placed after the ferrule assembly 2, so that the scattered area of ​​the fiber bundle is limited to a certain space, reducing the scattered area of ​​the fiber and facilitating the normal operation of subsequent fiber arrangement.

[0038] The process for fiber optic alignment is as follows:

[0039] First, the optical fiber is stripped and then cut. The cut optical fiber is then placed in the ferrule assembly 2. The optical fiber bundle placed in the ferrule assembly 2 is detected by the imaging assembly 1 to help determine the angle and position of the optical fiber. After the optical fiber is placed in the ferrule assembly 2, it is limited by the limiting assembly 3 to reduce the fiber scattering range. After the optical fiber is limited, the optical fiber bundle needs to be arranged in the fiber arrangement assembly 4. The arranged optical fiber is then placed in the position of the optical fiber rotator 5 and adjusted by the optical fiber rotator 5 to further adjust the angle and position of the optical fiber.

[0040] The specific structure of the ferrule assembly 2 is as follows:

[0041] See Figure 2 and Figure 3 The ferrule assembly 2 includes a ferrule slot 24, which has several V-shaped grooves, and optical fibers are arranged inside the V-shaped grooves.

[0042] See Figure 2 and Figure 3The ferrule assembly 2 also includes a worktable 21, with a slide rail 23 on the top of the worktable 21. An adjusting rod 22 is provided through the slide rail 23. The ferrule slot 24 is connected to the adjusting rod 22 by a thread, and the ferrule slot 24 is slidably connected to the slide rail 23.

[0043] See Figure 2 and Figure 3 The top of the insert slot 24 is provided with a limiting seat 27, and the inside of the limiting seat 27 is provided with a glass cover plate 28.

[0044] See Figure 2 and Figure 3 A mounting bracket 25 is provided on one side of the limiting seat 27. The mounting bracket 25 is L-shaped and a fixing rod 26 is provided through the mounting bracket 25. The fixing rod 26 is connected to the mounting bracket 25 by threads.

[0045] The limiting seat 27 has a limiting groove on the side opposite to the glass cover plate 28. The limiting groove is used to place the glass cover plate 28. The optical fiber can be placed through the V-shaped groove on the ferrule 24. After the optical fiber is placed in the V-shaped groove, the operator inserts the glass cover plate 28 into the limiting groove on the limiting seat 27 along the upper surface of the ferrule 24.

[0046] The adjusting rod 22 is connected to the slide rail 23, and the mounting bracket 25 is connected to the fixing rod 26 by threads. Therefore, by rotating the adjusting rod 22 and the fixing rod 26 respectively, the adjusting rod 22 and the fixing rod 26 can move along the slide rail 23 and the mounting bracket 25 respectively. In addition, the insert slot 24 can move horizontally under the drive of the adjusting rod 22.

[0047] The specific process for fiber optic cable placement is as follows:

[0048] First, the cut optical fibers are spliced ​​together and then placed into the V-grooves on the ferrule 24. Next, the glass cover plate 28 is inserted into the limiting seat 27 along the upper surface of the ferrule 24. The operator rotates the adjusting rod 22, and the ferrule 24 moves horizontally along the slide rail 23 under the action of the adjusting rod 22. When the end face of the optical fiber is aligned with the imaging component 1, the adjusting rod 22 is stopped, and then the fixing rod 26 is rotated. The fixing rod 26 descends to the surface of the glass cover plate 28 and limits and fixes the glass cover plate 28, reducing the possibility of optical fiber displacement.

[0049] After the optical fiber is placed in the ferrule assembly 2, the optical fiber will be in a scattered state before fiber arrangement. In order to reduce the scattered space, the optical fiber is limited by setting the limiting assembly 3.

[0050] The specific structure of the limiting component 3 is as follows:

[0051] See Figure 4 and Figure 5The limiting component 3 includes a first limiting block 36, and a second limiting block 37 is provided on one side of the first limiting block 36. The first limiting block 36 and the second limiting block 37 are arranged in an inverted V shape.

[0052] See Figure 4 and Figure 5 The limiting component 3 also includes a base 31, and a sliding rail 32 is provided on one side of the base 31. The sliding rail 32 and the base 31 are integrally formed.

[0053] See Figure 4 and Figure 5 A sliding block 34 is provided on one side of the sliding track 32. The sliding block 34 is slidably connected to the sliding track 32. A lead screw 33 is provided through the sliding track 32. The lead screw 33 is connected to the sliding block 34. The lead screw 33 is connected to the sliding track 32 by a thread.

[0054] See Figure 4 and Figure 5 A connecting plate 35 is provided at the bottom of the sliding block 34, and a first limiting block 36 and a second limiting block 37 are provided at the bottom of the connecting plate 35.

[0055] Specifically, by setting the first limiting block 36 and the second limiting block 37 into an inverted V-shape, when the optical fiber moves from the position of the ferrule assembly 2 to the position of the fiber arranging assembly 4 for fiber arranging, the optical fiber can be confined within the inverted V-shape range, reducing the space for optical fiber scattering before fiber arranging, and facilitating the normal operation of subsequent optical fiber arranging work.

[0056] Since the lead screw 33 is connected to the sliding rail 32 by threads, the lead screw 33 is connected to the sliding block 34, and the sliding block 34 is slidably connected to the sliding rail 32, when the operator rotates the lead screw 33, the sliding block 34 moves vertically along the sliding rail 32 under the drive of the lead screw 33. Since the connecting plate 35 is set at the bottom of the sliding block 34, the connecting plate 35 can move with the sliding block 34, and thus the first limiting block 36 and the second limiting block 37 move with the connecting plate 35.

[0057] In addition, a slot is provided on the top of the base 31. The shape of the slot is adapted to the inverted V-shape formed by the first limiting block 36 and the second limiting block 37. By setting the lead screw 33 to drive the first limiting block 36 and the second limiting block 37 to move, the positions of the first limiting block 36 and the second limiting block 37 can be changed. When the optical fiber is placed in the ferrule assembly 2, the lead screw 33 is activated. Driven by the lead screw 33, the first limiting block 36 and the second limiting block 37 descend to the position corresponding to the slot. The first limiting block 36, the second limiting block 37 and the slot form a limiting space to limit the optical fiber, reduce the range of optical fiber scattering, reduce the difficulty of operation for operators, and improve the fiber arrangement efficiency.

[0058] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
