International Patent Application and claims the benefit of Chinese Patent Application No. 201911341561.7, filed on December 24, 2019, the disclosure of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

The present disclosure relates generally to the field of optical fiber processing. More specifically, the present disclosure relates to an optical fiber processing apparatus. DESCRIPTION OF RELATED ART

As shown in FIG. 1, a common structure of an optical fiber comprises an uncoated bare fiber 1, a first buffer layer 2 and a second buffer layer 3 surrounding the uncoated bare fiber 1, and a sheath 4 surrounding the second buffer layer 3. A reinforcing layer 5 is usually further provided between the sheath 4 and the second buffer layer 3. The first buffer layer 2 and the second buffer layer 3 usually have different outer diameters. For example, the first buffer layer 2 may have an outer diameter of 250um, and the second buffer layer 3 may have an outer diameter of 900um. In some cases, it is necessary to first strip the second buffer layer 3 as well as other layers outside the second buffer layer to expose the first buffer layer 2, and then strip the exposed first buffer layer 2 to expose the uncoated bare fiber 1. However, current optical fiber stripping devices can only strip buffer layer in one size, but they cannot strip buffer layers in two different sizes.

In addition, current fiber stripping devices do not comprise a cleaning function. Therefore, an operator is required to actively and manually clean the exposed uncoated bare fiber. However, the operator sometimes will forget to clean the exposed uncoated bare fiber, which makes it difficult to control the cleaning quality of the uncoated bare fiber.

Referring to FIG. 2, an optical fiber processing apparatus 10 according to an embodiment of the present disclosure is shown. The optical fiber processing apparatus 10 may comprise a fixing module 11 for fixing an optical fiber and a stripping module 21 for stripping layers outside the uncoated bare fiber of the optical fiber. The stripping module 21 is configured to strip two or more sizes of layers outside the uncoated bare fiber. The optical fiber processing apparatus 10 may further comprise a cleaning module 31 for cleaning the exposed uncoated bare fiber and a cleaning agent supply module 41 for supplying a cleaning agent to the cleaning module 31. The fixing module 11, the stripping module 21, the cleaning module 31, and the cleaning agent supply module 41 may be arranged in a housing 51 with an appropriate layout. The housing 51 may be closed by a cover 61. The optical fiber processing apparatus 10 may be configured to perform optical fiber stripping and cleaning operations with the cover 61 closing the housing 51, so as to improve the safety of the optical fiber processing apparatus 10. To this end, an induction device may be arranged on the cover 61. The induction device is configured to allow the optical fiber processing apparatus 10 to be activated when it is sensed that the cover 61 is closed, and not allow the optical fiber processing apparatus 10 to be activated when it is sensed that the cover 61 is opened. Referring to FIG. 3, the fixing module 11 according to an embodiment of the present disclosure is shown. The fixing module 11 comprises a clamping member 110 for clamping and fixing the optical fiber, and a driving mechanism 112 for driving the clamping member 110 to clamp or release the optical fiber. The clamping member 110 may comprise a left clamping arm 114 and a right clamping arm 116. The left clamping arm 114 and the right clamping arm 116 may move toward or away from each other when driven by the driving mechanism 112, so as to clamp or release the optical fiber. The left clamping arm 114 and the right clamping arm 116 may each comprise a clamping portion. A support portion 118 may be provided below the clamping portion of the left clamping arm 114 to support the optical fiber, so as to prevent the optical fiber from falling down from a gap between the left clamping arm 114 and the right clamping arm 116 during the release process of the optical fiber. According to an embodiment of the present disclosure, the clamping portion of the left clamping arm 114 is made of a first material (such as a metal) which is relatively hard and the clamping portion of the right clamping arm 116 is made of a second material (such as a rubber) softer than the first material, which makes it possible to avoid damaging the optical fiber while maintaining a sufficient clamping force. The clamping portion of the right clamping arm 116 may comprise a recess, and the second material may be embedded in the recess. The left clamping arm 114 and the right clamping arm 116 may be mounted on a base 120 and may translate on the base 120. The driving mechanism 112 may be disposed below the base 120. According to an embodiment of the present disclosure, the driving mechanism 112 may be any suitable type of driving mechanism, such as pneumatic, hydraulic, mechanical, electrical driving mechanisms, and the like.

A specific structure of the stripping module 21 according to an embodiment of the present disclosure is described with reference to FIGS. 4 to 7. The stripping module 21 comprises a stripping member 210. The stripping member 210 is configured to strip two or more sizes of layers outside the uncoated bare fiber. Specifically, the stripping member 210 may comprise two bodies 212 and 214 arranged in parallel. Two or more kinds of blades 216 and 218 suitable for stripping different sizes of layers outside the uncoated bare fiber may be provided on each body 212 and 214. The bodies 212 and 214 are configured to be capable of performing translational movements toward and away from each other in a lateral direction, performing translational movements forward and backward in a longitudinal direction, and performing rotational movements about respective longitudinal axes. When it is intended to strip a layer of a first size outside the uncoated bare fiber, the blades of the bodies 212 and 214 that are suitable for stripping the layer of the first size are moved to face each other (as shown in FIG. 5), and the bodies 212 and 214 translate in the lateral direction towards each other to cut the blades into the layer of the first size that is intended to be stripped; then, the bodies 212 and 214 translate backward together in the longitudinal direction to strip the layer of the first size with the blades from the optical fiber. When it is intended to strip layers of other sizes outside the uncoated bare fiber, the bodies 212 and 214 are rotated around their respective longitudinal axes (as shown in FIG. 6), so that the blades of the bodies 212 and 214 that are suitable for stripping the layers of other sizes are moved to face each other (as shown in FIG. 7), and then follow the same steps as stripping the layer of the first size to strip the layers of other sizes.

In the embodiments shown in FIGS. 4 to 7, the bodies 212 and 214 have substantially rectangular cross sections. Two kinds of blades 216 and 218 are arranged on each body 212 and 214, which are arranged on opposite sides of each body 212 and 214, respectively. The blade 216 is suitable for stripping a layer of a first size outside the uncoated bare fiber (for example, a 250um buffer layer), and the blade 218 is suitable for stripping a layer of a second size different from the first size outside the uncoated bare fiber (for example, a 900um buffer layer). However, the present disclosure is not limited thereto. More kinds of blades may be arranged on each body 212 and 214 to enable the stripping member 210 to strip more sizes of layers outside the uncoated bare fiber. For example, three or four kinds of blades can be arranged on each body 212 and 214, and each kind of blade is located on a different side of the body 212 or 214, respectively. As needed, the bodies 212 and 214 can also be configured to have other shapes of cross sections (such as pentagons, hexagons, etc.) to facilitate the arrangement of more kinds of blades on the body. By arranging more kinds of blades on the bodies 212 and 214, the functions that the stripping member 210 can achieve may be further expanded, for example, the stripping member 210 may cut optical fibers (for example, by adding a cutting blade) in addition to stripping different sizes of layers outside the uncoated bare fiber of an optical fiber. The ability to cut optical fibers is important for a ribbon cable, since the ribbon cable generally comprises a plurality of optical fibers, ends of which might not be flush due to the optical fibers may have various lengths. Therefore, the ribbon cable may be first cut with the stripping member 210 to make the ends of the optical fibers flush, and then the optical fibers may be stripped. In addition, by arranging more kinds of blades on the bodies 212 and 214, the stripping member 210 may also suitable for stripping different sizes of layers outside the uncoated bare fiber of different kinds of optical fibers, thereby further improving the universality of the optical fiber processing apparatus 10.

In the embodiment in which two kinds of blades 216 and 218 are arranged on each body 212 and 214 as shown in FIGS. 4 to 7, one strip function of the stripping member 210 may be converted into a cutting function by changing one kind of blades. In this way, the stripping member 210 can perform two functions of cutting the optical fiber and stripping one size of layer outside the uncoated bare fiber. In the embodiment in which more kinds of blades are arranged on each body 212 and 214, multiple functions of cutting the optical fiber and stripping various sizes of layers outside the uncoated bare fiber may be realized without changing the blades.

The bodies 212 and 214 may comprise centered cavities 220. Heating elements may be disposed in the cavities 220 to heat the bodies 212 and 214 and the blades 216 and 218, so as to thermally strip the optical fiber. The heating elements may be configured in the form of heating rods. Thermocouples may be arranged at appropriate positions of the bodies 212 and 214 to measure the temperatures of the bodies 212 and 214 and the blades 216 and 218, and the operation of the heating elements is controlled based on the measured temperatures. In addition, the bodies 212 and 214 may further comprise limiting members to limit the relative positions of the bodies 212 and 214 during the stripping operation. As shown in FIGS. 5 to 7, extension posts 222 are provided on a side of the body 214, and holes 224 for receiving the extension posts 222 are provided on a side of the body 212. When the bodies 212 and 214 move toward each other to perform the stripping operation, the extension posts 222 of the body 214 extend into the holes 224 of the body 212 to ensure that the bodies 212 and 214 are aligned with each other and to ensure that the blades on the body 212 and the body 214 are aligned with each other.

According to an embodiment of the present disclosure, the translation of the bodies 212 and 214 of the stripping member 210 may be achieved by one or more driving mechanisms, which may be any suitable type of driving mechanism, such as pneumatic, hydraulic, mechanical, electrical driving mechanisms, and the like. The rotation of each body of the stripping member 210 is achieved by a specific driving mechanism according to an embodiment of the present disclosure. The specific driving mechanism is configured as a pneumatic cylinder including a rotor for rotating the body of the stripping member. One end of the rotor is connected to the body of the stripping member 210. The rotor may be mounted in two spaced apart bearings to facilitate the rotation of the rotor as well as the body of the stripping member 210. According to an embodiment of the present disclosure, the rotor of the pneumatic cylinder is configured to be rotated by the impact of an injection gas. The injection gas can be injected onto a surface of the rotor at an angle to rotate the rotor by an initial angle, and then continue to rotate the rotor by an additional angle by means of the rotational inertia of the rotor and the body of the stripping member 210. This way significantly saves the energy consumed by the pneumatic cylinder when driving the body of the stripping member. In addition, the rotor of the pneumatic cylinder may comprise a centered cavity, such that each heating element provided in the cavity 220 of the body of the stripping member or a wire connected to each heating element may extend through the cavity of the rotor. This facilitates the arrangement of the heating element and its wires.

Returning to FIG. 4, the stripping module 210 may comprise cleaning brushes 226 arranged face each other in a lateral direction and a cleaning nozzle 228 arranged above the stripping member 210 in a central position of the stripping member 210, so as to automatically clean the blades 216 and 218 by brushing the layers outside the uncoated bare fiber which are cut but remained on the blades 216 and 218. The cleaning brushes 226 are fixed to a frame at an appropriate angle, so that the cleaning brushes 226 can contact and clean the blades 216 or 218 in a non-working position when the bodies 212 and 214 are translated forward and backward in the longitudinal direction. The cleaning nozzle 228 can spray a cleaning gas (such as air) to clean the blades 216 or 218 in a working position. By the aid of the cleaning brushes 226 and the cleaning nozzle 228, the residues remained on the blades 216 and 218 (i.e., the layers outside the uncoated bare fiber that have been cut away) can be cleaned in a timely and effective manner, and the cleaning process is also made easier. If the residues remained on the blades 216 and 218 are not cleaned in time, the residues will be cooled down and thus adhere to the blades, which will make cleaning process difficult.

According to other embodiments of the present disclosure, the stripping member 210 may also be configured to comprise only one body. Two or more kinds of blades are disposed on the body in pairs. Each pair of the two or more kinds of blades are configured to face each other and be able to translate toward or away from each other, so that each pair of blades can cut into the layers outside the uncoated bare fiber of the optical fiber or release the optical fiber. The stripping member 210 may be configured to be able to translate forward and backward in the longitudinal direction. When stripping the optical fiber, a pair of the two or more kinds of blades may be translated toward each other to cut into the layers outside the uncoated bare fiber of the optical fiber, and then the stripping member 210 is translated backward in the longitudinal direction to strip the layers outside the uncoated bare fiber. Referring to FIGS. 8 to 10, the cleaning module 31 for cleaning the exposed uncoated bare fiber according to one embodiment of the present disclosure is shown. The cleaning module 31 may be configured to automatically clean the exposed uncoated bare fiber after the stripping module 21 performs a stripping operation. The cleaning module 31 may comprise cleaning tape assemblies 310 arranged facing each other in a lateral direction. Each cleaning tape assembly 310 may comprise a housing 312 and a cleaning tape 314 accommodated in the housing 312. A protrusion 316 is provided on the front side of the housing 312, and the cleaning tape 314 may be wound inside the housing 312 and a portion thereof protrude from the housing 312 under the support of the protrusion 316. The portion of the cleaning tape 314 supported by the protrusion 316 forms a cleaning portion for cleaning the exposed uncoated bare fiber. A button 318 is provided on the back side of the housing 312. When the button 318 is actuated, the cleaning tape 314 will advance by a predetermined length, so that the used portion of the cleaning tape 314 leaves the protrusion 316 and a new portion of the cleaning tape 314 is supported on the protrusion 316 for performing the next cleaning operation. Similar to the stripping members 210, the cleaning tape assemblies

310 may be configured to be able to translate toward and away from each other in a lateral direction, and forward and backward in a longitudinal direction. After the stripping members 210 strip the optical fiber to expose the uncoated bare fiber, the cleaning tape assemblies 310 are translated toward each other in the lateral direction, so that the cleaning portions of the cleaning tape assemblies 310 sandwich the exposed uncoated bare fiber therebetween. Then, the cleaning tape assemblies 310 are moved backward in the longitudinal direction, so that the portions of the cleaning tapes 314 supported by the protrusions 316 clean the uncoated bare fiber by wiping the exposed uncoated bare fiber. After cleaning the exposed uncoated bare fiber, the cleaning tape assemblies 310 are moved to their initial positions. When the cleaning tape assemblies 310 return to their initial positions, the button 316 of each cleaning tape assembly 310 will be in an actuated state to advance the cleaning tape 314 by a predetermined length, so that a new portion of the cleaning tape 314 is supported on the protrusion 316.

According to an embodiment of the present disclosure, each cleaning tape assembly 310 is clamped on a clamping assembly 320, which facilitates the replacement of the cleaning tape assembly 310. The clamping assemblies 320 are disposed on a support plate 322 and can be translated on the support plate 322 toward and away from each other in a lateral direction, thereby driving the cleaning tape assemblies 310 to be translated toward and away from each other in the lateral direction. The support plate 322 can be translated forward and backward in a longitudinal direction to drive the cleaning tape assemblies 310 fixed thereon to translate forward and backward in the longitudinal direction. The translational movement of the support plate 322 may be driven by one or more driving mechanisms 324 arranged below it. The driving mechanism 324 may be any suitable type of driving mechanism, such as pneumatic, hydraulic, mechanical, electrical driving mechanisms, and the like. According to an embodiment of the present disclosure, a motion conversion mechanism 326 is provided between the driving mechanism 324 and the clamping assemblies 320. The motion conversion mechanism 326 is configured to convert a motion in the vertical direction of the driving mechanism 324 into a translational movement of the clamp assembly 320 and thus the cleaning tape assembly 310 in the lateral direction. Specifically, the motion conversion mechanism 326 comprises an intermediate support 328 and two connecting rods 330. One end of each connecting rod 330 is pivotably connected to the clamping assembly 320, and the other end of each connecting rod 330 is pivotally connected to the intermediate support 328. When the intermediate support 328 moves in the vertical direction under the driving of the driving mechanism 324, the connecting rods 330 can pivotally move under the pushing or pulling of the intermediate support 328, so that the clamping assemblies 320 may move away or toward each other.

By the aid of the cleaning module 31 , the uncoated bare fiber can be automatically cleaned each time the optical fiber is stripped, and thus the cleaning quality can be ensured. In addition, the driving mechanism(s) 324 is/are used to move the cleaning tape assemblies 310, which can ensure that the clamping force applied to the uncoated bare fiber is the same each time, and which can ensure the consistency of the cleaning quality.

To better clean the uncoated bare fiber, a cleaning agent may also be applied on the cleaning tapes 314. To this end, the optical fiber processing apparatus 10 according to an embodiment of the present disclosure further comprises a cleaning agent supply module 41, which is described with reference to FIG. 11. The cleaning agent supply module 41 comprises a container 410 for containing the cleaning agent, pipes for conveying the cleaning agent to the cleaning module (more specifically, to positions above the portions of cleaning tapes 314 that protrude from the housings of the cleaning tape assemblies), and a control valve for controlling the automatic release of the cleaning agent. The cleaning agent may be dropped from the positions above the cleaning tapes 314 onto the cleaning tapes 314 under the control of the control valve. According to an embodiment of the present disclosure, the cleaning agent in the container 410 may be pumped by a pneumatic pump. The cleaning agent may be alcohol. According to an embodiment of the present disclosure, a controller may be provided to centrally control operations of the fixing module 11 , the stripping module 21, the cleaning module 31, and the cleaning agent supply module 41, thereby realizing the automation of the stripping and cleaning operations. The optical fiber processing apparatus 10 according to the present disclosure can not only strip the layers of different sizes outside the uncoated bare fiber, but also automatically clean the exposed uncoated bare fibers and ensure the cleaning quality of the uncoated bare fibers. Therefore, the processing efficiency and quality of the optical fibers are greatly promoted. Although exemplary embodiments of this disclosure have been described, those skilled in the art should appreciate that many variations and modifications are possible in the exemplary embodiments without departing from the spirit and scope of the present disclosure. Accordingly, all such variations and modifications are intended to be included within the scope of this disclosure as defined in the claims.
