Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication processing, specifically to a device for removing the coating layer of a conformal optical fiber. Background Technology

[0002] Traditional fiber optic coating removal typically involves placing the fiber on an auxiliary pull-out platform, inserting one end into a coating removal device, closing the device, and horizontally pulling the fiber out of the cutting edge to remove the coating. Because the auxiliary platform pulls the fiber horizontally, when the fiber is parallel and one end is fixed, the length from the stripped end to the fixed end is essentially the same, meaning the stripping cut is perpendicular to the fiber. With the continuous development of fiber optic communication technology, fiber optics are increasingly widely used in modern communication networks. In the manufacturing process of fiber optic products, it is often necessary to fix one end of multiple parallel fibers (hereinafter referred to as the fixed end) and bend the other end (hereinafter referred to as the movable end) to a certain angle before manufacturing the product. In actual production, when the movable end is bent at a large angle, a difference will occur in the distance from the fiber stripping position to the fixed end between the fiber closer to the bend center and the fiber further away from the bend center. Specifically, the fiber stripping position closer to the bend center on the movable end is closer to the fixed end, while the fiber stripping position further away from the bend center is further away from the fixed end. This results in a difference in fiber stripping position, which is more pronounced when the fiber bend angle is large. This positional difference will cause some fibers to be exposed on the outside of the connector after being inserted into the movable end connector without the protection of the coating. This can easily lead to reliability risks for the product. For example, the fiber may be susceptible to interference from external factors due to lack of protection, resulting in fiber breakage or damage, which will affect the overall performance and service life of the product. Utility Model Content

[0003] The purpose of this invention is to provide a conformal fiber coating stripping device, which is applied to scenarios where multiple parallel optical fibers are fixed at one end and the other end needs to be bent to a certain angle before manufacturing products. By adjusting the angle between the fiber axis and the stripping blade, the fiber coating can be stripped at an angle to compensate for the difference in the coating stripping position after bending. This ensures that the coating stripping position of the movable fiber is consistent in the connector, avoiding the product reliability risk caused by the fiber part inserted into the connector being exposed in the connector without the protection of the cladding layer.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A contoured optical fiber coating stripping device includes an optical fiber coating stripping device, a stripping base, and an angle adjustment block. The stripping base is fixedly connected to the optical fiber coating stripping device. The angle adjustment block is disposed above the stripping base and is fixedly connected to the stripping base at an adjustable angle. The end of the angle adjustment block near the optical fiber coating stripping device has several optical fiber limiting grooves, which correspond to the cutting edge position of the optical fiber coating stripping device. The angle adjustment block is slidably fixedly connected to a positioning support, and a positioning block is fixedly connected to the positioning support. The positioning block has a wire hole, and the wire hole is horizontally corresponding to the position of the optical fiber limiting groove.

[0006] Furthermore, the fiber stripping base has concentric first arc-shaped stepped holes and second arc-shaped stepped holes. The larger ends of the first arc-shaped stepped holes and the second arc-shaped stepped holes are located on the bottom surface of the fiber stripping base. The side of the fiber stripping base has a first mounting hole. The fiber stripping base is fixedly connected to the fiber coating removal equipment through a first bolt and the first mounting hole. The first arc-shaped stepped hole is close to the fiber coating removal equipment and its arc length is smaller than that of the second arc-shaped stepped hole.

[0007] Furthermore, the bottom surface of the angle adjustment block has two mounting screw holes. The angle adjustment block is fixedly connected to the fiber stripping base by passing a second bolt through the first arc-shaped stepped hole, the second arc-shaped stepped hole, and the two mounting screw holes. A sliding groove is provided at one end of the upper surface of the angle adjustment block, and the fiber limiting groove is provided at the other end of the upper surface of the angle adjustment block. Several symmetrical positioning screw holes are provided on both sides of the sliding groove.

[0008] Furthermore, the positioning support is placed in the slide groove and is fixedly connected to the angle adjustment block by set screws passing through the positioning screw holes and pressing against both sides of the positioning support.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention features a fiber stripping base and an angle adjustment block. By adjusting the angle between the angle adjustment block and the fiber stripping base, the angle between the fiber axis and the cutting edge of the fiber coating stripping device can be adjusted, enabling tilted angle stripping of the fiber cladding. This allows parallel fibers to be stripped along an oblique direction, resulting in shorter stripped coatings on fibers with the movable end further away from the bend center and longer stripped coatings on fibers closer to the bend center. This compensates for differences in the stripping position after bending, ensuring consistent stripping positions within the connector. This avoids product reliability risks caused by exposed fiber portions without cladding protection, thus improving product reliability and stability. Attached Figure Description

Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0018] Please see Figures 1-5 One embodiment provided by this utility model:

[0019] A contour-following optical fiber coating removal device includes an optical fiber coating removal device 1, a fiber removal base 2, and an angle adjustment block 3. The fiber removal base 2 is fixedly connected to the optical fiber coating removal device 1. The angle adjustment block 3 is located above the fiber removal base 2 and is fixedly connected to the fiber removal base 2 at an adjustable angle. Two optical fiber limiting grooves 302 are provided on one end of the angle adjustment block 3 near the optical fiber coating removal device 1. The optical fiber limiting grooves 302 correspond to the cutting edge position of the optical fiber coating removal device 1, which facilitates the removal of the optical fiber coating by the optical fiber coating removal device 1. The angle adjustment block 3 is slidably fixedly connected to a positioning support 4. A positioning block 5 is fixedly connected to the positioning support 4. The positioning block 5 has a wire hole, and the position of the wire hole corresponds horizontally to the position of the optical fiber limiting groove 302.

[0020] The fiber stripping base 2 has concentric first arc-shaped stepped holes 201 and second arc-shaped stepped holes 202. The larger ends of the first arc-shaped stepped holes 201 and the second arc-shaped stepped holes 202 are located on the bottom surface of the fiber stripping base 2, for the second bolt 7 to pass through from the bottom to fix the fiber stripping base 2 and the angle adjustment block 3, preventing the second bolt 7 from interfering with the fiber limiting groove 302. By adjusting the position of the second bolt 7 in the first arc-shaped stepped holes 201 and the second arc-shaped stepped holes 202, the angle between the angle adjustment block 3 and the fiber stripping base 2 can be adjusted. The side of the fiber stripping base 2 has a first mounting hole 203. The fiber stripping base 2 is fixedly connected to the fiber coating removal device 1 through the first bolt 6 and the first mounting hole 203. The first arc-shaped stepped hole 201 is close to the fiber coating removal device 1 and its arc length is smaller than that of the second arc-shaped stepped hole 202, so that the angle adjustment block 3 can be freely adjusted within a certain angle range.

[0021] The angle adjustment block 3 has two mounting screw holes 303 on its bottom surface. The angle adjustment block 3 is fixedly connected to the fiber stripping base 2 by passing the second bolt 7 through the first arc-shaped stepped hole 201, the second arc-shaped stepped hole 202 and the two mounting screw holes 303. A sliding groove 301 is provided at one end of the upper surface of the angle adjustment block 3, and an optical fiber limiting groove 302 is provided at the other end of the upper surface of the angle adjustment block 3. Several symmetrical positioning screw holes 304 are provided on both sides of the sliding groove 301.

[0022] The positioning support 4 is placed in the slide groove 301 and is fixedly connected to the angle adjustment block 3 by the set screws 8 passing through the positioning screw holes 304 and pressing against both sides of the positioning support 4.

[0023] Working principle of this utility model:

[0024] First, align the front end of the angle adjustment block 3 with the front end of the fiber stripping base 2. Place the optical fiber in the optical fiber limiting groove 302, inserting one end into the wire hole of the positioning block 5 and the other end into the optical fiber coating removal device 1. Based on the required length of the optical fiber coating to be stripped, move the positioning support 4 to confirm the stripping position. Then, fix the positioning support 4 and positioning block 5 onto the angle adjustment block 3 by tightening the set screw 8. Strip the optical fiber coating and insert it into the product to verify if the required length is met. Perform contouring operations (twisting, bending, etc.) on the product to confirm the bending condition of the optical fiber. Adjust the angle between the angle adjustment block 3 and the fiber stripping base 2 so that the angle is the same as the bending angle of the optical fiber. After stripping the optical fiber coating, insert it into the product to confirm if the stripped ends of the optical fiber inside the product are flush. After the first piece is confirmed, batch stripping operations can begin.
