Referring to fig. 1, the present invention provides a fiber stripping apparatus 100 capable of simultaneously stripping coating layers of a plurality of optical fibers. For ease of understanding, the following description will be made in conjunction with the structure of an existing optical fiber, but not as a limitation to the embodiment of the present invention.
The optical fiber comprises a core layer, a cladding layer and a coating layer, wherein the cladding layer surrounds the outside of the core layer and is used for forming an optical waveguide. The coating layer is wrapped outside the cladding layer and used for protecting the core layer and the cladding layer integrally. Typically, the core and cladding of the optical fiber are made of quartz and the coating is made of a polymer, which may be specifically epoxy, polyurethane, silicone. Optical fibers have many different applications, and in some applications, an optical waveguide formed by a core layer and a cladding layer needs to be operated, and a coating layer wrapping the outer portion of the optical waveguide needs to be stripped.

The holding assembly 20 is disposed on the support 10 for holding and fixing the optical fiber 200 so that the portion of the optical fiber 200 to be stripped is maintained at a certain tension to ensure a constant position of the optical fiber 200 during the whole stripping process. The fiber stripping assembly 30 is arranged on the bracket 10 and is used for stripping coating layers.
The support 10 is formed by splicing aluminum alloy sections and comprises a cross beam 11 and a plurality of supporting legs 12, wherein the cross beam 11 is erected above the supporting legs 12 and serves as an installation carrier for the fixing assembly 20 and the fiber stripping assembly 30.

It will be appreciated that the surfaces of the first and second clamping portions 211 and 212 are provided with a rubber coating to ensure that the optical fibre 200 is clamped.
Each clamping unit 21 is correspondingly provided with at least one auxiliary plate 22, the auxiliary plate 22 is provided with a plurality of limiting parts 221, each optical fiber 200 is respectively placed in one of the limiting parts 221, and the optical fibers 200 are arranged in parallel, so that the shearing direction of the cutter 34 can be perpendicular to the axial direction of the optical fibers 200, and the stripping assembly 30 can conveniently strip the optical fibers 200 at the same time. When stripping, the cutter 34 moves along the axial direction of the optical fiber 200 to strip the coating layer on the optical fiber 200, and since the plurality of optical fibers 200 are arranged in parallel, the stripped part of each optical fiber 200 has the same length, and the stripping length of the fiber stripping device 100 of the present invention has good consistency. In addition, in the fiber stripping process, the relative positions of the optical fibers 200 are kept unchanged, so that the optical fibers 200 are convenient to transfer to the next process.
In one embodiment, the position-limiting portion 221 is a position-limiting hole penetrating through the auxiliary plate 22 along the thickness direction, and the centers of the position-limiting holes are arranged in a straight line. It will be appreciated that the diameter of the stop hole is greater than or equal to the cross-sectional diameter of the optical fiber 200.
In other embodiments, the position-limiting portion 221 may also be a V-shaped groove or a groove penetrating the upper end surface of the auxiliary plate 22. It should be noted that the limiting portions 221 on the plurality of auxiliary plates 22 correspond to each other one by one, and a central connecting line of the limiting portions 221 correspondingly disposed on two adjacent auxiliary plates 22 is parallel to the extending direction of the support 10. The height of the stopper 221 is kept equal to the height of the clamping surface of the first clamping portion 211.
Referring to fig. 3 and 4, the fiber stripping assembly 30 includes a mounting seat 31, a connecting block 32, a plurality of guiding columns 33 and a cutter 34, the mounting seat 31 is slidably connected to the bracket 10, the connecting block 32 is disposed opposite to the mounting seat 31, the guiding columns 33 are disposed between the mounting seat 31 and the connecting block 32, the connecting block 32 can move along the guiding columns 33 to approach or separate from the mounting seat 31, the cutter 34 includes a first cutting piece 341 and a second cutting piece 342, the first cutting piece 341 is disposed on the mounting seat 31, and the second cutting piece 342 is disposed on the connecting block 32.
Due to the limiting effect of the bracket 10, the displacement of the mounting seat 31 in the direction perpendicular to the bracket 10 is 0, i.e. the mounting seat 31 is stationary relative to the connecting block 32. The action flow of fiber stripping comprises the following steps: the connecting block 32 moves towards the direction close to the mounting seat 31 under the guiding action of the guiding column 33, so as to drive the second slice 342 to be close to the first slice 341, and the gap between the second slice 342 and the first slice 341 is equal to the diameter of the optical fiber 200 after the coating layer is removed, so as to form a notch on the optical fiber 200; then, the cutter 34 is moved along the axial direction of the optical fiber 200 by the mount 31, and the coating layer on the optical fiber 200 is stripped.
In the fiber stripping assembly 30, the knife edges of the first section 341 and the second section 342 are always kept parallel to each other, so that the depths of the cuts formed on the optical fibers 200 by the first section 341 and the second section 342 are consistent, and the thicknesses of the coating layers scraped from the optical fibers 200 are consistent, thereby realizing synchronous fiber stripping operation on the optical fibers 200 and improving the fiber stripping efficiency.

A notch is formed on the optical fiber 200 through the first cutter 34a, and then the coating layer is scraped at the depth corresponding to the notch through the second cutter 34b, so that the optical waveguide structure in the optical fiber 200 is prevented from being damaged in the fiber stripping process due to the fact that the hardness of the second cutter 34b is low, and the fiber stripping yield is improved.
Specifically, the first cutter 34a is made of metal, and the second cutter 34b is made of plastic. The first cutter 34a is disposed at one side of the mount 31, and the second cutter 34b is disposed at the other side of the mount 31.

The carrier plate 35 is located between the first cutter 34a and the second cutter 34b, and the upper surface of the carrier plate 35 lifts the optical fiber 200, so that the optical fiber 200 is engaged with the first section 341 of the first cutter 34a or the second cutter 34b, and thus the moving stroke of the second section 342 can be adjusted with the first section 341 as a reference to adjust the distance between the first section 341 and the second section 342 to a target value.
In one embodiment, the fiber stripping assembly 30 further comprises an elastic member 38, and the elastic member 38 is disposed between the mounting seat 31 and the bearing plate 35.

The tensioning assembly 40 further includes a support base 42, the support base 42 being slidably connected to the bracket 10. The support table 42 is located below the weight plate 41 to bear the weight of the weight plate 41.

The stripped optical fiber 200 is removed by the transfer module 50 for the next process operation. The operation time of fiber threading in the next procedure is saved, the coating layer is prevented from being scratched by human introduction in the fiber threading process, and the working efficiency and the product yield are improved.

10. A method of stripping fibers by using the fiber stripping device according to any one of claims 1 to 9, comprising the steps of:
placing a plurality of optical fibers in a clamping unit, and enabling the parts of the optical fibers to be stripped to be in the processing range of a cutter;
fixing the position of the optical fiber through a clamping unit;
bringing the second section of the first cutter close to the first section of the first cutter to form a cut at an end of a portion of the plurality of optical fibers to be stripped;
moving the first section of the second cutter and the second section of the second cutter to the end part of the optical fiber to be stripped, wherein the second cutter can be closed to the depth corresponding to the cut and moves along the axial direction of the optical fiber to remove the coating layer of the part of the optical fiber to be stripped;
wherein the hardness of the first cutter is greater than the hardness of the second cutter.
