Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber processing equipment, and in particular to an optical fiber cleaning machine and a cleaning method. Background Art

[0002] Fiber optic cleaning is a key process, which is mainly used to ensure that the surface of the optical fiber remains clean and free of contamination during dispensing, welding or other subsequent processes. Contaminants such as dust, grease and other tiny particles on the surface of the optical fiber can significantly affect the transmission performance of the optical fiber, resulting in signal loss, increased attenuation and even connection failure. Therefore, the fiber optic cleaning process is crucial. After cleaning, the optical fiber end face needs to be inspected using a microscope or a fiber end face detector to ensure that the cleaning effect meets the standard requirements. An efficient cleaning process can not only improve the stability and reliability of the optical fiber connection, but also extend the service life of the equipment and reduce maintenance costs. Therefore, optical fiber cleaning is an indispensable part of the fields of optical fiber communication, laser processing, etc., which directly affects the performance and quality of the final product.

[0003] At present, the common method of cleaning optical fibers is to use dust-free paper dipped in anhydrous alcohol to repeatedly scrub the optical fiber surface. This cleaning method mainly relies on manual cleaning operations, and the product cleaning consistency is poor and the cleaning efficiency is low. Summary of the invention

[0019] Further preferably, it also includes a position detection component, which is arranged on the machine body and is used to detect the position of the detection hole of the cleaning segment in the moving direction of the sponge belt so that the connection between two adjacent cleaning segments avoids the cleaning station.

[0020] On the basis of the above technical solution, preferably, the optical fiber fixture includes a base, a carrier plate, a gland and a clamping part, wherein:

[0021] The base is arranged on the machine body;

[0022] The carrier plate is fixed on the base, and a plurality of optical fiber placement grooves are provided on the carrier plate;

At the same time, cutting the concave-convex structure at the end of the sponge can ensure the convenient operation of gluing, and ensure the quickness of splicing and the convenience of alignment.

[0049] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] like Figure 1-7 As shown, the optical fiber cleaning machine of the present invention comprises a machine body 1, two retractable mechanisms 2, two sponge belts 3, an optical fiber fixture 4 and a spraying mechanism 5.

[0051] A cleaning station is arranged on the machine body 1. The machine body 1 is a vertical structure as a whole. Four universal wheels are arranged at the bottom for its movement. A control host is arranged on the front of the machine body 1. The front of the machine body 1 is open so that the optical fiber can enter the cleaning station of the machine body 1 from the front of the machine body 1. Two openings are provided on both sides of the machine body 1 for activity space of the retracting mechanism 2. In addition, two driving parts are arranged on the machine body 1, one of which is used to drive the optical fiber fixture 4 to move back and forth. Specifically, a working platform is arranged on the front of the machine body 1, and a connecting bracket extending to the inside of the machine body 1 is arranged on the working platform. By driving the connecting bracket to move back and forth, the optical fiber is driven to move back and forth. The other driving part is used to drive the two retracting mechanisms 2 to move toward or away from each other to compress or leave the optical fiber.

[0052] The two retractable mechanisms 2 are relatively arranged on the body 1 and can move toward the cleaning station. Specifically, the two retractable mechanisms 2 extend to the outside of the body 1 through openings on both sides of the body 1. The driving part connecting the two retractable mechanisms 2 in the body 1 can be controlled by a driving part such as a cylinder.

[0053] The two sponge belts 3 are arranged on the two retracting and releasing mechanisms 2 in a one-to-one manner, and both ends of a single sponge belt 3 are wound onto the same retracting and releasing mechanism 2. The two sponge belts 3 extend to both sides of the cleaning station, specifically the upper and lower sides of the cleaning station. During the cleaning operation, the two retracting and releasing mechanisms 2 move toward the cleaning station from the upper and lower sides, so that the two sponge belts 3 squeeze the optical fiber from the upper and lower sides. This arrangement is considered to be more convenient for operation by arranging the optical fiber horizontally, and the pressing and cleaning operation is achieved through the upper and lower sides. The retracting and releasing mechanism 2 is used to switch the section of the sponge belt 3 facing the cleaning station, and drive the two sponge belts 3 to press the optical fiber on the cleaning station. When the sponge belt 3 at the cleaning station completes the cleaning operation or needs to be replaced, one end of the sponge belt 3 is tightened by the retracting and releasing mechanism 2, and the other end of the sponge belt 3 is released at the same time, thereby replacing the section of the sponge belt 3 located on the cleaning station, and then further cleaning of the optical fiber or cleaning of the next batch of optical fibers is carried out.

[0054] In this embodiment, the sponge belt 3 is selected as the main cleaning tool for the optical fiber because the cloth has less elasticity when squeezed than the sponge. When the pressing force is small, it is difficult to fully cover the surface of the optical fiber. When the pressing force is large, the reciprocating motion of the optical fiber is likely to form hard friction with the cloth.

[0055] The optical fiber fixture 4 is movably arranged on the body 1 and can reciprocate along a straight line. The optical fiber fixture 4 is used to clamp the optical fiber and extend the part of the optical fiber to be cleaned to the cleaning station. The length direction of the optical fiber is parallel to the straight line along which the optical fiber fixture 4 reciprocates. Specifically, the optical fiber fixture 4 is arranged on a connecting bracket of the body 1, and the connection form is preferably detachable and fixed. Before performing the cleaning operation, the optical fiber must first be arranged horizontally on the optical fiber fixture 4 for fixation, and then the optical fiber fixture is installed on the connecting bracket, and one end of the optical fiber to be cleaned enters the cleaning station. The optical fiber fixture 4 is arranged in front of the cleaning station, that is, the operating side of the body 1, to facilitate the operator to replace the optical fiber and assemble and disassemble the fixture.

[0056] The spraying mechanism 5 is arranged on the body 1 and is located outside the cleaning station. The spraying mechanism 5 is used to spray cleaning liquid to the cleaning station. Specifically, the spraying mechanism 5 is arranged on the upper retractable mechanism 2. When the retractable mechanism 2 is away from the cleaning station, the spraying mechanism 5 leaves the cleaning station with the upper retractable mechanism 2. During the cleaning operation, the spraying mechanism 5 sprays cleaning liquid onto the sponge belt 3 to moisten the sponge belt 3, so as to reduce the friction when the sponge belt 3 and the optical fiber move relative to each other, and effectively remove the stains on the surface of the optical fiber. The cleaning liquid in this embodiment can be directly selected as alcohol. The spraying mechanism 5 includes a mounting bracket and a nozzle. The number of nozzles can be selected according to the length of the sponge belt 3 used in the cleaning process. Specifically, two nozzles can be selected, and the nozzles are directed toward the end face of the optical fiber.

[0057] In this embodiment, the two retracting mechanisms 2 are respectively arranged on the upper and lower sides of the cleaning station, and can move synchronously toward and away from the cleaning station. The driving component is preferably a motor and a screw rod linked together. The motor drives the screw rod to rotate, and a bidirectional thread is arranged on the screw rod to be threadedly connected to the two retracting mechanisms 2 respectively. In a single rotation action, the two retracting mechanisms 2 can be driven to move synchronously toward or away from the cleaning station to squeeze or leave the optical fiber at the same time. The straight line along which the optical fiber fixture 4 moves is perpendicular to the moving direction of the retracting mechanism 2, and the optical fiber coding direction is parallel to the sponge belt 3, so that when the two sponge belts 3 press the optical fiber, the pressing effect on each optical fiber is the same.

[0058] It should be noted that, in order to further ensure the squeezing effect of the sponge belt 3 on the optical fiber, squeezing plates are provided on the two retracting and releasing mechanisms 2, and the sponge belt 3 is supported by the squeezing plates so that the sponge belt 3 can be evenly pressed on each optical fiber.

[0059] As a preferred embodiment, the reel-to-reel mechanism 2 includes a crossbeam 21, a reel-to-unwind 22 and a reel-to-wind 23. The crossbeam 21 is movably arranged on the machine body 1. The reel-to-unwind 22 is arranged on one end of the crossbeam 21. One end of the sponge belt 3 is wound on the reel-to-unwind 22. The reel-to-unwind 22 is used to store unused segments of the sponge belt 3. The reel-to-wind 23 is arranged on the other end of the crossbeam 21. The other end of the sponge belt 3 is wound on the reel-to-wind 23. The reel-to-wind 23 is used to wind up the used segments of the sponge belt 3.

[0060] The crossbeams 21 of the two retracting and unwinding mechanisms 2 are symmetrically arranged up and down, and the driving part of the body 1 drives the retracting and unwinding mechanisms 2 to move by connecting the crossbeams 21. The unwinding reel 22 is arranged on the left end of the retracting and unwinding mechanism 2, and the winding reel 23 is arranged on the right end of the crossbeam 21. The winding reel 22 is driven to rotate by a motor to rewind the sponge belt 3. During the rewinding process, a certain pulling force will be formed on the sponge belt 3, and the unwinding reel 22 is provided with a certain damping. The sponge belt 3 is tightened by the damping provided, so that the surface of the sponge belt 3 has a certain tension. During the cleaning operation, the unwinding reel 22 can provide the clean sponge belt 3 required for cleaning, and the winding reel 23 is used to rewind the contaminated sponge belt 3.

[0061] In addition, the spraying mechanism 5 is arranged on the cross beam 21 of the upper storage mechanism 2, and performs a spraying operation of the cleaning liquid from the front of the cleaning station toward the cleaning station.

[0062] In actual operation, there is no finished sponge belt 3 available for purchase. Usually, a whole piece of sponge needs to be purchased, cut into pieces, and connected to form the sponge belt 3 required for cleaning operation. Therefore, it is inevitable that a splicing position will be formed on the sponge belt 3. Specifically, the sponge belt 3 includes a plurality of cleaning segments 31 connected end to end. The cleaning segment 31 is provided with a detection hole 301, and the detection hole 301 is located on the outside of the connection between two adjacent cleaning segments 31. The detection hole 301 is used to identify the splicing position of the cleaning segment 31 of the sponge belt 3, so as to avoid the splicing position from contacting the optical fiber during the cleaning operation, thereby preventing the solidified colloid adhered to the splicing position from scratching the optical fiber, thereby improving the quality of the optical fiber cleaning operation.

[0063] As a preferred embodiment, a protrusion 302 is provided at one end of the cleaning segment 31, and a slot 303 is provided at the other end. The protrusion 302 is adapted to the slot 303, and the protrusion 302 of a cleaning segment 31 is inserted into the slot 303 of another adjacent cleaning segment 31. The detection hole 301 is provided on the end of the cleaning segment 31 where the protrusion 302 is located.

[0064] By providing the protrusion 302 and the slot 303, the Dingmao mosaic structure connection of the two adjacent cleaning segments 31 is realized, so that the mutual friction between the high-density sponges and the snap-fit ​​form are utilized to improve the connection force generated when the sponges are spliced, and the tensile strength of the sponge belt 3 is increased, which can avoid the problem of two adjacent cleaning segments 31 being easily pulled apart due to direct end face bonding. At the same time, cutting this concave-convex structure at the end of the sponge can ensure the convenient operation of gluing, and ensure the quickness of splicing and the convenience of alignment.

[0065] Correspondingly, in this embodiment, a position detection component 6 is also provided, and the position detection component 6 is arranged on the body 1. The position detection component 6 is used to detect the position of the detection hole 301 of the cleaning segment 31 in the moving direction of the sponge belt 3, so that the connection between two adjacent cleaning segments 31 avoids the cleaning station.

[0066] The position detection component 6 is preferably a laser sensor, which determines the position of the detection hole 301 by emitting a laser beam, thereby further determining the splicing position of the sponge belt 3. Specifically, the position detection component 6 can be arranged before the cleaning station, and the cleaning operation can be started when the detection hole 301 reaches the position detection component 6. In addition, the length of each cleaning segment 31 can be set to a uniform length, and the number of times each cleaning segment 31 can be moved for cleaning is determined. The retracted length is controlled by the retracting mechanism 2 to achieve a high utilization rate of the cleaning operation of the cleaning segment 31. At this time, the detection of the detection hole 301 by the position detection component 6 is used as a position correction of the sponge belt 3. The reason why the sponge belt 3 is not directly retracted and released by the retracting mechanism 2 for continuous cleaning operations is that the sponge has a certain elasticity, and the retracting process may cause a small deviation at the connection at different lengths. In order to avoid the accumulation and superposition of deviations caused by multiple movements, it is necessary to correct it in each cleaning segment 31 through the position detection component 6.

[0067] In this embodiment, the optical fiber fixture 4 includes a base 41, a carrier plate 42, a pressure cover 43 and a clamping portion 44. The base 41 is arranged on the body 1, and the carrier plate 42 is fixed on the base 41. A plurality of optical fiber placement grooves are opened on the carrier plate 42. The pressure cover 43 is placed flat on the carrier plate 42 to confine the optical fiber in the optical fiber placement groove. The clamping portion 44 is arranged on the base 41, and the pressure cover 43 is used to press the pressure cover 43 toward the carrier plate 42 so that the pressure cover 43 presses the optical fiber onto the carrier plate 42.

[0068] Rubber gaskets are provided in the optical fiber placement grooves of the carrier plate 42 to provide buffering when the optical fibers are compressed to avoid excessive or insufficient compression force, and at the same time make the compression of each optical fiber more uniform. When installing the optical fiber, it is necessary to remove the pressure cover 43 from the carrier plate 42. After the optical fibers are arranged, the pressure cover 43 is installed on the carrier plate 42. The pressure cover 43 can be installed on the carrier plate 42 by means of magnets, thereby realizing rapid positioning of the pressure cover 43 during installation. In addition, in this embodiment, two carrier plates 42 are provided to realize the simultaneous cleaning operation of more optical fibers.

[0069] In order to achieve rapid compression of the optical fiber, the optical fiber fixture 4 also includes a quick pressing mechanism 45, which is arranged on the base 41 and is transmission-connected to the compression part 44, and is used to push the compression part 44 and limit the position of the compression part 44.

[0070] The optical fiber is quickly and effectively compressed by the quick pressing mechanism 45. It should be noted that when the quick pressing mechanism 45 is set, its stroke needs to be accurately set to avoid the problem of insufficient or excessive compression force resulting from too small or too large downward pressing stroke.

[0071] Specifically, the quick pressing mechanism 45 includes a movable seat 451, a transverse plate 452, an elastic member 453 and a pushing member 454. The movable seat 451 is arranged on the base 41 and can move toward and away from the base 41. An arc-shaped eccentric opening 4511 is provided on the movable seat 451. The transverse plate 452 is arranged on the movable seat 451 and extends to the side of the pressure cover 43 away from the carrier plate 42. The clamping portion 44 is fixed on the transverse plate 452. The elastic member 453 is arranged on the base 41 and connected to the movable seat 451. The elastic member 453 is used to push the movable seat 451 to make the transverse plate 452 away from the pressure cover 43. The pushing member 454 is hinged on the base 41 and extends into the arc-shaped eccentric opening 4511. The pushing member 454 can squeeze the movable seat 451 toward the carrier plate 42 through the arc-shaped eccentric opening 4511.

[0072] There are two movable seats 451, elastic members 453 and pushing members 454 of the quick pressing mechanism 45, which are symmetrically arranged on both sides of the carrier plate 42. The two elastic members 453 and the movable seats 451 are used as supports on both sides of the cross plate 451 so that the pressing force will not be larger at one end and smaller at the other end when it is pressed down. During operation, the operator simultaneously pulls the two pushing members 454 to press the cross plate 452.

[0073] In addition, a roller is provided on the pushing member 454, and the roller is inserted into the arc-shaped eccentric opening 4511. The resistance of the pushing member 454 during rotation is reduced by rolling friction. The distance between the top end of the arc-shaped eccentric opening 4511 and the rotation axis of the pushing member 454 is smaller than the distance between the bottom end of the arc-shaped eccentric opening 4511 and the rotation axis of the pushing member 454. After the roller of the pushing member 454 is pushed to the top end of the arc-shaped eccentric opening 4511, the roller can press the movable seat 451 downward. It should be noted that the position where the pushing member 454 is pressed and locked should exceed the position where the pushing member 454 is perpendicular to the cross plate 452, so that the movable seat 451 will not drive the roller to slide in the arc-shaped eccentric opening 4511 under the reaction force of the elastic member 453. The elastic member 453 provided can be selected as a spring, which is installed on the base 41 by bolts, and the two ends respectively abut the base 41 and the movable seat 451.

[0074] The optical fiber cleaning method of the present invention is implemented based on the above-mentioned optical fiber cleaning machine and includes steps S1-S6.

[0075] Step S1: Install the optical fiber on the optical fiber fixture 4, and place the end of the optical fiber to be cleaned at the cleaning station.

[0076] In this step, first remove the pressure cover 43 of the optical fiber fixture 4, arrange the optical fiber in the optical fiber placement groove, cover the pressure cover 43, and press the movable seat 451 downward by the pushing member 454, so that the cross plate 452 drives the clamping part 44 to clamp the pressure cover 43, and the optical fiber clamping operation can be completed. It should be noted that during the clamping process, the end of the optical fiber to be cleaned needs to face the cleaning station of the machine body 1.

[0077] Step S2: the spraying mechanism 5 sprays the cleaning liquid toward the sponge belt 3 facing the cleaning station.

[0078] The spray cleaning liquid is sufficient to completely soak the three sections of the sponge belt facing the cleaning station. The amount of spray cleaning liquid can be directly achieved by a peristaltic pump or other pump body.

[0079] Step S3: The two retracting and releasing mechanisms 2 move toward the cleaning station, so that the two sponge belts 3 squeeze the optical fiber to be cleaned from both sides.

[0080] The driving part of the machine body 1 drives the two retracting and releasing mechanisms 2 to move synchronously toward the cleaning station, and causes the two sponge belts 3 to squeeze the arranged.

[0081] Step S4: The optical fiber fixture 4 drives the optical fiber to move back and forth for single cleaning.

[0082] Step S5: After a single cleaning is completed, the two retracting and releasing mechanisms 2 move away from the cleaning station, and replace the portion of the sponge belt 3 facing the cleaning station by retracting and releasing.

[0083] Step S6: Repeat steps S2-S5 until the cleaning operation is completed.

[0084] Cleaning is divided into rough cleaning, medium cleaning and fine cleaning. Taking rough cleaning as an example, after completing the rough cleaning according to steps S2-S5, the two retracting mechanisms 2 move away from the cleaning station, and then the unwinding reel 22 unwinds and the reel 23 reels, that is, step S5 ends, thereby completing a single cleaning, and then performing medium cleaning and fine cleaning in the same steps to complete the overall optical fiber cleaning operation.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
