Description

Technical Field

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

[0002] In the process of producing fiber gratings, it is necessary to strip off the coating layer in the middle section of the optical fiber, optically write on the bare fiber part and then re-coat it. Before coating the optical fiber, the bare fiber of the written part needs to be carefully cleaned, and during the cleaning process, it is necessary to avoid damaging the conical coating section formed in the previous stripping process, otherwise it will affect the coating effect.

[0003] When cleaning the bare fiber portion of the optical fiber after the middle window is opened, the existing technology is to manually wipe the bare fiber with a dust-free cloth dipped in alcohol, or to clean the optical fiber with an automatic wiping device coated with soft material. Even if the existing wiping device is coated with soft material, the coating material is very fragile, and the wiping device is not flexible enough in controlling the wiping force. Excessive wiping force can easily damage the conical coating section of the windowed optical fiber. Maintaining the conical coating section is beneficial to subsequent processes.

[0032] The optical fiber tensioning mechanism 4 includes a support frame 41, an elastic member 46, two slide rails and a tensioning drive device 42. The upper end surface 411 of the support frame 41 is provided with a tensioning slide groove 413 along the horizontal arrangement direction X. The second optical fiber rotation mechanism 2 includes a slider 24. The second fiber clamping device 21 and the second rotation drive device 22 are arranged on the slider 24 and can move together with the slider 24. The second fiber clamping device 21 is located above the upper end surface 411, and the second rotation drive device 22 is located below the upper end surface 411. The slide rail is arranged in the tensioning slide groove 413 and is respectively located on both sides of the slider 24. Specifically, the slide rail includes a first sub-rail 231 and a second sub-rail 232. The first sub-rail 231 is fixedly connected to the edge of the tensioning slide groove 413, and the second sub-rail 232 is connected to the side wall of the slider 24. Through the connection between the first sub-rail 231 and the second sub-rail 232, the first sub-rail 231 and the second sub-rail 232 can be relatively slidably matched, and the slider 24 can move along the horizontal arrangement direction X relative to the tensioning slide groove 413.

[0033] The slider 24 is fixedly connected with a reset block 241, which is located below the upper end surface 411. The reset block 241 is provided with a guide slope 242, which is inclined to the horizontal arrangement direction X. The outer end of the guide slope 242 has an access opening, and the inner end of the guide slope 242 is provided with a positioning step 243.

[0034] The slider 24 is also fixedly connected with a first fixed block 244, which has a hook portion. A second fixed block 414 is arranged on the side wall 412 of the support frame 41, and the second fixed block 414 has a hook portion. The elastic member 46 is a spring, which extends along the horizontal arrangement direction X and is connected between the first fixed block 244 and the second fixed block 414.

[0035] The optical fiber tensioning mechanism 4 also includes a rotating block 43, multiple rollers 44, a roller 441, a position detection sheet 451 and two position sensors 452. The tensioning drive device 42 can use a motor. The rotating block 43 is connected to the output shaft of the tensioning drive device 42. The extension direction of the rotating block 43 is perpendicular to the output shaft of the tensioning drive device 42 and also perpendicular to the horizontal arrangement direction X. The tensioning drive device 42 drives the rotating block 43 to rotate around the horizontal arrangement direction X. The axial direction of the roller 441 is perpendicular to the horizontal arrangement direction X. The roller 441 is fixedly connected to the rotating block 43 and rotates with the rotating block 43. Multiple rollers 44 are sleeved outside the roller 441 and can rotate around the axial direction of the roller 441. The roller 44 is used to roll with the guide ramp 242. The position detection sheet 451 is fixedly connected to the rotating block 43 and rotates with the rotating block 43. The two position sensors 452 are respectively located on both sides of the position detection sheet 451. When the rotating block 43 rotates to two different positions, the position detection sheet 451 also rotates to two different positions, and then the position sensor 452 can detect and know the rotation position. A processing position 30 is provided between the first fiber clamping device 11 and the second fiber clamping device 21, and the first fiber groove 111 and the second fiber groove 211 are arranged in a colinear manner.

[0036] The optical fiber cleaning method applied to the above optical fiber cleaning device includes: First, fix the first end of the optical fiber to be cleaned in the first optical fiber groove 111 .

[0037] Then, refer to Figure 8 The rotating block 43 is rotated by the tensioning driving device 42, and then the roller 44 drives the guiding inclined surface 242 to move along the horizontal arrangement direction X close to the processing position 30, that is, the second optical fiber rotating mechanism 2 is driven to move close to the processing position 30. At this time, the roller 44 is located at the positioning step 243, so that the position of the second optical fiber rotating mechanism 2 is stable.

[0038] Reference Fig. 9 , and then fix the second end of the optical fiber to be cleaned in the second optical fiber groove 211. Subsequently, the rotating block 43 is rotated by the tensioning driving device 42 to disengage the roller 44 from the guiding inclined surface 242. Then, the elastic member 46 drives the second optical fiber rotating mechanism 2 to move away from the processing position 30. The elastic member 46 applies a tensioning force to the second optical fiber rotating mechanism 2 along the horizontal arrangement direction X away from the processing position 30, so that the optical fiber to be cleaned remains taut.

[0039] Finally, the bare wire portion of the optical fiber to be cleaned in the processing position 30 is cleaned respectively by the dry ice nozzle 32 and the ion air gun 31. During cleaning, the XY-axis moving device can be moved in the XY direction, and the first optical fiber groove 111 and the second optical fiber groove 211 can be rotated around the horizontal arrangement direction, thereby achieving all-round cleaning of the bare wire portion.

[0040] Reference Fig.10 , Fig.10 The principle of using a carbon dioxide dry ice cleaner to clean optical fibers is to mix the tiny dry ice particles produced by the equipment with compressed air and spray them onto the surface of the optical fiber. The tiny dry ice particles impact the surface of the optical fiber to peel off the attachments. The dry ice sublimates and absorbs heat to cool the surface of the optical fiber, further enhancing the peeling force. The tiny explosion effect produced during the sublimation process causes the attachments to completely fall off and are taken away with the compressed air.

[0041] Different from traditional cleaning methods, this cleaning method is to spray tiny dry ice particles on the surface of the optical fiber. The dry ice quickly sublimates and vaporizes on the surface of the optical fiber. The temperature difference and impact force generated during the sublimation process loosen the oil or dust on the surface of the optical fiber and then are carried away by the compressed air flow. This method does not require the use of a dust-free cloth to directly contact the optical fiber, avoiding damage to the coating cross-section during the cleaning process. In addition, the cleaning effect only requires adjusting the size of the sprayed dry ice particles and the pressure of the compressed air, which are adjusted through the generator, and the cleaning consistency can be guaranteed. The cleaning time using this method is comparable to manual cleaning, but after automation, one person can operate multiple devices to improve cleaning efficiency.

[0042] Of course, the above embodiment is only a preferred embodiment of the present case. In specific applications, there may be more variations, such as directly using a rotating block adjacent to the guiding inclined surface, and driving the guiding inclined surface to move close to the processing position along the horizontal arrangement direction X through the rotating block, or using other types of tensioning driving devices, such as a telescopic driving device, which can also realize the driving of the second optical fiber rotating mechanism. Alternatively, elastic members such as torsion springs and tension springs can also be used to apply tension to the second optical fiber rotating mechanism.

[0043] As can be seen from the above, by fixing the first end of the optical fiber to be cleaned in the first optical fiber groove, the second optical fiber rotating mechanism can be moved close to the processing position through the rotating block and the roller and the rolling cooperation with the guide inclined surface, and then the second optical fiber rotating mechanism is located in a relatively relaxed position, and then the second end of the optical fiber to be cleaned is fixed in the second optical fiber groove, and then the roller can be driven to disengage from the guide inclined surface, and the position sensor can be used for position detection, and then under the elastic recovery action of the spring, the elastic member drives the second optical fiber rotating mechanism to move away from the processing position to keep the optical fiber to be cleaned taut, and finally the dry ice nozzle and the ion air gun respectively clean the bare wire part of the optical fiber to be cleaned in the processing position, and during cleaning, the XY-axis moving device can be moved in the XY direction, and the first optical fiber groove and the second optical fiber groove can be rotated around the horizontal arrangement direction, thereby achieving all-round cleaning of the bare wire part.
