Description

Technical Field

[0001] This invention relates to the field of optical fiber manufacturing technology, specifically to an optical fiber end face fusion splicing device. Background Technology

[0002] Fiber fusion splicing devices are the core equipment for achieving efficient fiber optic connections. Their performance directly determines the transmission quality and reliability of fiber optic links. However, traditional fiber fusion splicing devices still have defects in use. Traditional fiber optic fusion splicing devices typically employ an integrated, fixed clamping mechanism. The clamping foot is rigidly connected to the inner side of the windproof cover. Over long-term use, the rubber clamping block of the clamping foot will wear down due to repeated squeezing of the optical fiber, resulting in a decrease in the clamping force on the optical fiber. This can easily lead to the optical fiber shifting during splicing, affecting the alignment accuracy of the splice. Furthermore, when the rubber clamping block is worn or damaged, the entire clamping foot mechanism or even the windproof cover needs to be replaced. This not only involves a cumbersome replacement process but also increases equipment maintenance costs and downtime. Traditional fiber optic fusion splicing devices often employ a fixed heating element design for their heating mechanism. The heating element is typically a single planar structure, installed at the bottom or side of the heating platform. During heat shrinking, the heat shrink tubing only contacts a localized area of ​​the heating element. The large temperature difference between different locations on the heat shrink tubing can easily lead to wrinkles or bubbles, affecting the overall protective effect. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides the following technical solution: an optical fiber end-face fusion splicing device, comprising: The fusion splicer includes a main body and a base fixedly installed at the bottom of the main body. A fusion splicing mechanism is fixedly installed on the top of the main body, and a connecting shaft is provided on one side of the fusion splicing mechanism. The connecting shaft is fixedly installed on the top of the fusion splicer via a bracket. A windproof cover is rotatably installed on the outer surface of the connecting shaft. The windproof cover can effectively block the interference of external airflow on the fusion splicing area during the fusion process, avoiding arc instability or affecting the fiber optic splicing quality due to airflow. A display screen is rotatably installed on one side of the fusion splicer via a rotating shaft. The display screen is used to display the working status, parameter settings, fiber image, and other information of the fusion splicer, so that the operator can understand the fusion process in real time and make timely adjustments and judgments. A control panel is installed on the top of the fusion splicer near the display screen. The control panel is used to set fusion parameters and control the start and stop of the fusion splicer. The pressure foot mechanism is installed on the inner side of the windproof cover. The pressure foot mechanism is squeezed and adapted to the fusion splicing mechanism. The pressure foot mechanism is used to press the optical fiber to prevent the optical fiber from shifting during the fusion splicing process and to ensure the accuracy of the fusion splicing. The heating mechanism is installed on one side of the top of the fusion splicer body. The heating mechanism and the control panel are arranged opposite each other on both sides of the fusion splicer body. The heating mechanism is used to heat the heat shrink tubing so that it shrinks and wraps around the fused optical fiber, thereby protecting the fusion splice. The presser foot mechanism includes a mounting block and a fixing component. The mounting block is fixedly installed on the inner side of the windshield. The surface of the mounting block has two slots. The two sides of the slots have receiving grooves. The slots have mounting holes. The fixing component is detachably installed inside the slots. The slots and fixing components engage to allow for the detachable installation of the fixing component, facilitating replacement and maintenance.

[0004] Preferably, the fixing component includes a snap-fit ​​bracket and an I-shaped sliding plate. The snap-fit ​​bracket is snap-fitted into a slot. A sliding groove is formed at each of the four corners of the outer surface of the snap-fit ​​bracket. An elastic locking block is slidably installed inside the sliding groove. The elastic locking block is slidably installed inside the receiving slot. The four corners of the I-shaped sliding plate are snap-fitted into the elastic locking block. A rubber pressure block is fixedly installed on the surface of the I-shaped sliding plate. A buffer spring is fixedly installed on the side of the I-shaped sliding plate away from the rubber pressure block. The buffer spring provides elastic force to the I-shaped sliding plate, causing the rubber pressure block to press the optical fiber. The other end of the buffer spring is located inside a mounting hole, which is used to fix the buffer spring. When the windproof cover is closed, the rubber pressure block will press the optical fiber, preventing displacement of the optical fiber during splicing and ensuring the accuracy of splicing.

[0005] Preferably, the fusion splicing mechanism includes a work box, which is fixedly installed on the top of the fusion splicer body. Fine-tuning seats are installed on both sides of the top of the work box. These seats are used for precise position adjustment of the optical fibers placed on top, allowing for minute movements in the horizontal and vertical directions to ensure accurate alignment of the two optical fibers to be fused, thereby improving the success rate and quality of the fusion splicing. A placement pad is fixedly installed on the top of the fine-tuning seat. This placement pad is made of silicone, possessing a certain degree of softness and friction, which avoids damage to the optical fiber and ensures its stability during placement, preventing damage during adjustment or splicing. If displacement occurs during the process, a pressure cap is rotatably installed on one side of the top of the fine-tuning seat. The pressure cap can be rotated and closed to further fix the optical fiber and prevent it from changing position due to external forces or other factors during the fusion splicing process, thus ensuring the accuracy of the fusion splicing. A mounting base is fixedly installed in the middle of the top of the work box. Placement parts are installed on both sides of the top of the mounting base. A microscope is fixedly installed in the middle of the top of the mounting base. Electrodes are set on both sides of the mounting base. The electrodes are detachably installed on the top of the work box. The electrodes generate a high-temperature electric arc during fusion splicing. The high temperature of the electric arc is used to melt the end faces of the two optical fibers to be fused, so that the two optical fibers can be fused together to complete the fusion splicing work.

[0006] Preferably, there are two microscopes, which are arranged opposite each other on the top of the mounting base. The alignment of the optical fiber and the splicing process can be clearly observed on the display screen through the microscopes, so as to make timely adjustments and ensure the accuracy and quality of the splicing. A handle is fixedly installed on one side of the pressure cap.

[0007] Preferably, the placement component includes a placement block that is squeezed and adapted to a rubber pressure block. The placement block is used to place the optical fiber. A V-shaped groove is provided on the top of the placement block, which allows the optical fiber to fall naturally into and be positioned, facilitating subsequent fusion splicing operations. A positioning groove is provided in the middle of the V-shaped groove, which further improves the accuracy of optical fiber positioning and prevents it from shifting in the horizontal direction.

[0008] Preferably, the heating mechanism includes a heating platform, a cover plate is rotatably mounted on one side of the top of the heating platform via a rotating shaft, a U-shaped groove is formed on the top of the heating platform, a sliding groove is formed in the middle of the U-shaped groove, a receiving groove is formed in the middle of the heating platform, the receiving groove is arranged on both sides of the U-shaped groove, and a heating element is installed inside the sliding groove.

[0009] Preferably, a pressure pad is fixedly installed in the middle of the surface of the cover plate. When the cover plate is closed, the pressure pad can apply pressure to the heat shrink tubing placed in the U-shaped groove. Handles are fixedly installed on both sides of the cover plate, which facilitates the operator to open and close the cover plate.

[0010] A magnetic strip is fixedly installed on the top of the inner wall of the second receiving groove, and the magnetic strip is magnetically attracted to the heating element.

[0011] Preferably, the heating element includes a slider, which is slidably installed inside the slide groove. A return spring is fixedly connected between the bottom of the slider and the inner wall of the slide groove. A semi-circular heating plate is fixedly installed on the top of the slider. Rotating shafts are fixedly installed on both sides of the top of the semi-circular heating plate through brackets. An arc-shaped heating plate is rotatably installed on the outer surface of the rotating shaft.

[0012] Preferably, a closing spring is sleeved in the middle of the outer surface of the rotating shaft. The two ends of the closing spring are respectively fixedly installed on the surfaces of the arc-shaped heating plate and the semi-circular heating plate. The elastic force of the closing spring can make the arc-shaped heating plate automatically close when there is no external force, thus ensuring the heating effect. The arc-shaped heating plate is set inside the receiving groove two. The semi-circular heating plate is squeezed and adapted to the inner wall of the U-shaped groove. The heat generated by the semi-circular heating plate and the arc-shaped heating plate heats the heat shrink tube placed in the U-shaped groove, causing it to shrink and wrap around the fused optical fiber, thus protecting the fused part.

[0013] Preferably, a magnetic stripe 1 is fixedly installed on the outer curved surface of the arc-shaped heating plate. The magnetic stripe 1 and magnetic stripe 2 are magnetically attracted to each other. When the optical fiber covered with heat shrink tubing is placed on the top of the semi-circular heating plate, the cover is closed, the pressure pad squeezes the heat shrink tubing and causes the slider to move downward. The magnetic stripe 1 gradually separates from the magnetic stripe 2. Under the elastic force of the closing spring, the arc-shaped heating plate closes and together with the semi-circular heating plate, heat shrinks the heat shrink tubing. After heat shrinking is completed, the cover is opened, and under the elastic force of the reset spring, the slider moves upward, the magnetic stripe 1 approaches the magnetic stripe 2 again and is magnetically attracted to each other, and the arc-shaped heating plate opens.

[0014] This invention provides an optical fiber end-face fusion splicing device. It has the following advantages: 1. This optical fiber end-face fusion splicing device, through the setting of the pressure foot mechanism, when the windproof cover is closed, the mounting block drives the fixing component to move down, the snap-fit ​​bracket is positioned in the snap-fit ​​slot, the elastic snap-fit ​​block is snapped into the receiving slot to achieve fixation, the I-shaped sliding plate pushes the rubber pressure block through the elastic force of the buffer spring, and squeezes and fits with the placement block to tightly press the optical fiber. The elastic snap-fit ​​block and the buffer spring cooperate to realize the detachable installation of the fixing component, which is convenient for replacing the worn rubber pressure block. The pressure foot mechanism presses the optical fiber to ensure that the optical fiber does not shift during the fusion splicing process and improves the alignment accuracy.

[0015] 2.

The operator observes the images transmitted by two opposing microscopes through the display screen, adjusts the fine adjustment seat to realize the slight movement of the optical fiber until the axis is completely aligned. The dual microscopes provide multi-angle observation to ensure that the mating end faces are aligned and improve the fusion splicing success rate.

[0016] Third, this optical fiber end face fusion splicing device, through the setting of the windproof cover and electrodes, the windproof cover is closed during fusion splicing, forming a closed space to block the external airflow, and the electrodes generate a stable electric arc under the control of the control panel, using high temperature to melt the end face of the optical fiber to achieve fusion, thereby improving work efficiency.

[0017] IV. In this optical fiber end-face fusion splicing device, after the heat shrink tubing is placed on the semi-circular heating plate and the cover plate is closed, the pressure pad pushes the slider down, the first magnetic strip disengages from the second magnetic strip, and the arc-shaped heating plate closes under the action of the closing spring, forming a closed heating space with the semi-circular heating plate. After heat shrinking is completed, the reset spring pushes the slider up, the first magnetic strip and the second magnetic strip attract each other, the arc-shaped heating plate opens, and the heating mechanism heats the heat shrink tubing evenly, avoiding the generation of bubbles or wrinkles.

[0018] 5. This optical fiber end face fusion splicing device, through the setting of the placement component, allows the bare fiber to fall naturally into the V-shaped groove after the coating is stripped off. The positioning groove restricts horizontal sliding, and together with the friction of the placement pad and the pressure of the pressure cap, the optical fiber is fixed. The placement component improves the positioning efficiency of the optical fiber. Attached Figure Description

The placement block 261 is used to place optical fibers. A V-shaped groove 262 is provided on the top of the placement block 261. The V-shaped groove 262 allows the optical fiber to fall naturally into and be positioned, which facilitates subsequent fusion splicing operations. A positioning groove 263 is provided in the middle of the V-shaped groove 262. The positioning groove 263 further improves the accuracy of optical fiber positioning and prevents it from shifting in the horizontal direction. The pressure foot mechanism 4 is installed on the inner side of the windproof cover 3. The pressure foot mechanism 4 is pressed and adapted to the fusion splicing mechanism 2. The pressure foot mechanism 4 is used to press the optical fiber to prevent the optical fiber from shifting during the fusion splicing process and to ensure the accuracy of the fusion splicing. Heating mechanism 5 is installed on one side of the top of the fusion splicer body 1. Heating mechanism 5 and control panel 7 are set opposite each other on both sides of the fusion splicer body 1. Heating mechanism 5 is used to heat the heat shrink tubing so that it shrinks and wraps around the fused optical fiber, thus protecting the fused part.

[0023] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 6 to 8 As shown, the presser foot mechanism 4 includes a mounting block 41 and a fixing member 45. The mounting block 41 is fixedly installed on the inner side of the windproof cover 3. The surface of the mounting block 41 is provided with a slot 42. There are two slots 42. The two sides inside the slot 42 are provided with receiving grooves 43.

The fastener 45 includes a snap-fit ​​bracket 451 and an I-shaped sliding plate 454. The snap-fit ​​bracket 451 is snapped into and adapted to the slot 42. Slide grooves 452 are formed at the four corners of the outer surface of the snap-fit ​​bracket 451. Elastic blocks 453 are slidably installed inside the slide grooves 452. The elastic blocks 453 are slidably installed inside the receiving slots 43. The four corners of the I-shaped sliding plate 454 are snapped into and adapted to the elastic blocks 453. Rubber pressure blocks 45 are fixedly installed on the surface of the I-shaped sliding plate 454. 5. A buffer spring 456 is fixedly installed on the side of the I-shaped slide plate 454 away from the rubber pressure block 455. The buffer spring 456 is used to provide elastic force to the I-shaped slide plate 454, so that the rubber pressure block 455 presses the optical fiber. The other end of the buffer spring 456 is set inside the mounting hole 44. The mounting hole 44 is used to fix the buffer spring 456. When the windproof cover 3 is closed, the rubber pressure block 455 will press the optical fiber to prevent the optical fiber from shifting during the fusion splicing process and ensure the accuracy of the fusion splicing.

[0024] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figure 9 and Figure 10As shown, the heating mechanism 5 includes a heating platform 51. A cover plate 55 is rotatably mounted on one side of the top of the heating platform 51 via a rotating shaft. A U-shaped groove 52 is provided on the top of the heating platform 51. A sliding groove 53 is provided in the middle of the U-shaped groove 52. A receiving groove 54 is provided in the middle of the heating platform 51. The receiving groove 54 is arranged on both sides of the U-shaped groove 52. A heating element 58 is installed inside the sliding groove 53. A pressure pad 56 is fixedly installed in the middle of the surface of the cover plate 55. When the cover plate 55 is closed, the pressure pad 56 can apply pressure to the heat shrink tubing placed in the U-shaped groove 52. Handles 57 are fixedly installed on both sides of the cover plate 55. The handles 57 make it convenient for operators to open and close the cover plate 55. A magnetic strip 2 59 is fixedly installed on the top of the inner wall of the receiving groove 2 54. The magnetic strip 2 59 is magnetically attracted to the heating element 58. The heating element 58 includes a slider 581, which is slidably installed inside the slide groove 53. A return spring 583 is fixedly connected between the bottom of the slider 581 and the inner wall of the slide groove 53. A semi-circular heating plate 582 is fixedly installed on the top of the slider 581. Rotating shafts 584 are fixedly installed on both sides of the top of the semi-circular heating plate 582 through brackets. An arc-shaped heating plate 585 is rotatably installed on the outer surface of the rotating shaft 584. A closing spring 586 is sleeved in the middle of the outer surface of the rotating shaft 584. The two ends of the closing spring 586 are fixedly installed on the surfaces of the arc-shaped heating plate 585 and the semi-circular heating plate 582, respectively. The elastic force of the closing spring 586 can make the arc-shaped heating plate 585 automatically close when there is no external force, thus ensuring the heating effect. The arc-shaped heating plate 585 is set inside the receiving groove 54. The semi-circular heating plate 582 is squeezed and matched with the inner wall of the U-shaped groove 52. The heat generated by the semi-circular heating plate 582 and the arc-shaped heating plate 585 heats the heat shrink tube placed in the U-shaped groove 52, causing it to shrink and wrap around the fused optical fiber, thus protecting the fused part. A magnetic strip 587 is fixedly installed on the outer curved surface of the arc-shaped heating plate 585. The magnetic strip 587 and the magnetic strip 59 are magnetically attracted to each other. When the optical fiber covered with heat shrink tubing is placed on top of the semi-circular heating plate 582, the cover plate 55 is closed. The pressure pad 56 squeezes the heat shrink tubing, causing the slider 581 to move downward. The magnetic strip 587 gradually separates from the magnetic strip 59. Under the elastic force of the closing spring 586, the arc-shaped heating plate 585 closes and together with the semi-circular heating plate 582 heat shrinks the heat shrink tubing. After the heat shrinking is completed, the cover plate 55 is opened. Under the elastic force of the return spring 583, the slider 581 moves upward, and the magnetic strip 587 approaches the magnetic strip 59 again for magnetic attraction. The arc-shaped heating plate 585 is then opened.

[0025] When in use, the operator places the fusion splicer on the table, opens the windproof cover 3 and the display screen 6, checks the cleanliness of the placement pad 23 and placement piece 26 in the fusion splicing mechanism 2, and places the two cut optical fibers to be fused on the placement pad 23 of the fine adjustment seats 22 on both sides, so that the ends of the optical fibers are aligned with the placement piece 26 in the middle of the fusion splicing mechanism 2. The optical fiber is naturally positioned in the V-shaped groove 262 of the placement block 261. The positioning groove 263 further restricts horizontal displacement. The pressure cover 24 is rotated to press the optical fiber tightly. The placement pad 23 is used to prevent the optical fiber from sliding. The windproof cover 3 is closed. The rubber pressure block 455 of the pressure foot mechanism 4 moves down with the windproof cover 3 and is squeezed and matched with the placement block 261. The elastic force of the buffer spring 456 further presses the optical fiber to avoid displacement during splicing. The operator starts the alignment program through the control panel 7. The microscopes 27 on both sides transmit the fiber optic images to the display screen 6 to observe whether the fiber end faces are aligned. If there is a deviation, adjust the fine adjustment seat 22 until the axes of the two fibers are completely aligned. After alignment, the splicing parameters are set through the control panel 7 and the splicing program is started. The electrode 28 on the top of the work box 21 generates a high-temperature arc, which instantly melts the bare fiber end face at the fiber connection. During the splicing process, the windproof cover 3 blocks external airflow interference to ensure the stability of the arc. The display screen 6 displays the splicing status in real time. The operator can pause or adjust at any time through the control panel 7. After the fusion splicing is completed, open the windproof cover 3, take out the fused optical fiber, move the heat shrink tube pre-fitted on the optical fiber to the fusion splicing part, and place it into the U-shaped groove 52 of the heating mechanism 5. Rotate the cover plate 55 and the pressure pad 56 to squeeze the heat shrink tube to fit the optical fiber. At this time, the slider 581 of the heating element 58 moves down along the second slide groove 53 under the pressure of the pressure pad 56, the first magnetic strip 587 disengages from the second magnetic strip 59, and the arc heating plate 585 closes under the action of the closing spring 586, forming a closed heating space with the semi-circular heating plate 582. Start the heating program through the control panel 7. The semi-circular heating plate 582 and the arc heating plate 585 heat up synchronously. The heat shrink tube shrinks when heated, tightly wrapping the fusion splicing part to complete the protection. After heating is complete, open the cover plate 55. The slider 581 moves upward under the action of the return spring 583. The magnetic strip 1 587 and magnetic strip 2 59 are magnetically attracted again. The arc-shaped heating plate 585 is opened and stored in the receiving slot 2 54. Take out the optical fiber, turn off the display screen 6 and the power of the machine body, and complete the entire fusion splicing process.
