Description

Technical Field

[0001] The utility model relates to the field of optical fiber assembly, in particular to an ultra-long optical fiber assembly device. Background Art

[0002] Optical fiber is an important communications device widely used in communications, electricity, energy, and other fields. During optical fiber assembly, due to its length, if the fiber is bent, stretched, or subjected to external forces during the assembly process, it is very easy to crack or even break, which significantly increases production costs. To address this problem, optical fiber components must be installed outside the fiber. However, optical fiber components may become contaminated, damaged, or loosened over long periods of use, affecting the transmission quality of optical signals. Furthermore, the stability and durability of optical fiber components in harsh environments remain a key focus of technological development, requiring further improvements in the corrosion resistance and high-temperature resistance of optical fiber materials and structures.

[0003] However, due to the significant differences in the physical properties of optical fibers and metal components, traditional fiber optic connection methods are not robust and precise. This leaves room for improvement in terms of connection reliability, durability in harsh environments, and quality control during production. Furthermore, the fiber optic connection process directly impacts performance, including surface quality, coating adhesion, gas leakage rate, and optical loss. Existing fiber optic assembly devices have limitations and cannot meet these requirements.

A plurality of angle positioning holes 19 matching the positioning balls are provided on the angle adjustment plate 14, and the plurality of angle positioning holes 19 are distributed at equal central angles.

[0029] The end fixture 17 includes a first clamping plate 20 and a second clamping plate 21 connected as an integral structure by bolts, and the first clamping plate 20 is provided with an end receiving groove 22.

[0030] The rolling support mechanism includes a pair of rolling support plates 24. The tops of the two rolling support plates 24 are respectively rotatably supported by an active roller 25 and a passive roller 26. An optical fiber fixing plate 27 is supported between the active roller 25 and the passive roller 26. The optical fiber fixing plate 27 is composed of two semicircular half-plate structures.

[0031] The active roller 25 is connected to the active shaft 28, and the active shaft 28 is connected to the drive shaft through a bevel gear transmission pair 29. The drive shaft is rotatably supported on a drive mechanism bracket 30, and a hand wheel 31 is also provided at the tail end of the drive shaft.

[0032] A driving shaft support plate 32 is further provided on the base plate 1 . The driving shaft support plate 32 is located between the two driving mechanism brackets 30 . The driving shaft support plate 32 rotates the driving shaft 28 through the bearing.

[0033] The working process of the ultra-long optical fiber assembly device of the embodiment of the present invention is as follows: in the non-working state, the two bracket slides 3 are located in the middle of the base plate 1. At this time, the bracket slides 3 are fixedly connected to the slide fixing seat 4 located in the middle of the base plate 1 by fixing bolts 5. At the same time, under the action of gravity, the bracket 6 naturally swings down (the bracket plate 7 with a relatively large mass is located at a lower position), and the bracket positioning pins 10 on the first connecting plate 8 are inserted into the positioning holes provided on the vertical plates of the bracket slides 3 to limit the position of the bracket 6;

[0034] When it is necessary to use this device to assemble optical fibers, first loosen the fixing bolts 5 to release the lock on the bracket slide 3, then manually push the bracket slide 3 to allow it to move to the end of the slide rail 2, and then re-use the fixing bolts 5 to connect the bracket slide 3 with the slide fixing seat 4 there to achieve the positioning of the bracket slide 3; then pull out the bracket positioning pins 10 on the first connecting plate 8 from the positioning holes, manually rotate the bracket 6, and let the second connecting plate 9 swing to a position that contacts the side of the vertical plate on the bracket slide 3, and then use the bracket positioning pins 10 to position the bracket 6 in the current state. At this time, the bracket plate 7 and the optical fiber fixing plate 27 supported by the rolling support mechanism are basically at the same level;

[0035] The optical fiber 33 is pre-threaded into the metal fixing tube 34. First, the metal fixing tube 34 is moved to a designated relative position on the optical fiber 33. Then, two optical fiber fixing plates 27 are connected to both ends of the metal fixing tube 34. At this time, the metal fixing tube 34 is supported by the two optical fiber fixing plates 27, and the optical fiber fixing plates 27 are supported by the active roller 25 and the passive roller 26.

[0036] The packaged ends 35 are pre-mounted on the optical fibers 33 outside the two ends of the metal fixing tube 34 and are clamped by two end fixtures 17 (the packaged ends 35 are located in the end receiving groove 22).

[0037] The operator first drives the end fixture 17 to rotate, and stops when it is adjusted to the appropriate angle. A part of the positioning ball will automatically embed into the corresponding angle positioning hole 19, allowing the end fixture 17 (and the packaging end 35 thereon) to stop at the current tilt angle; through this adjustment, the opening of the packaging end 35 is tilted upward, making it easier for the operator to pour the powdered adhesive into the packaging end 35.

[0038] Then, according to the change of the above-mentioned tilt angle, the overall height of the end clamp 17 is adjusted, the height positioning pin 15 is pulled out, and the height adjustment plate 13 is driven to adjust the position in the longitudinal direction. After adjusting to the appropriate height, the height positioning pin 15 is reinserted into the current corresponding height positioning hole 16 to ensure that the packaging end 35 clamped on the end clamp 17 is at the same horizontal height as the metal fixing tube 34, which makes it easier to adjust the direction and bending angle of the optical fiber.

[0039] After pouring adhesive into the openings of both packaged ends 35, first heat one of the packaged ends 35 (end A), melt the adhesive, and then cool it. Then apply a layer of protective glue on the surface of the adhesive. Bond the packaged end 35 at end A to the optical fiber to form an integrated structure. Then restore the packaged end 35 to a horizontal state, open the end fixture 17, pull the optical fiber 33 toward end B, and move the packaged end 35 at end A toward the metal fixing tube 34. Let the packaged end 35 enter the metal fixing tube 34, ensuring that the distance between the end face of the packaged end 35 and the end face of the metal fixing tube 34 is H (as shown in the figure). Figure 7 shown),

[0040] Then adjust the distance between the package end 35 at the B end and the end face of the metal fixing tube 34 to ensure that the distance between the two is also H. Repeat the above operation in this state to fix the package end 35 at the B end to the optical fiber 33, and apply adhesive on the outer wall of the package end 35 (the coating length is half of the length of the package end 35). Then pull the optical fiber 33 towards the A end. The pulling distance must be greater than H. Since the optical fibers at both ends are already fixed, there is no need to limit the pulling distance. It is only necessary to ensure that half of the package end 35 is exposed. , half of it is inserted into the mouth of the metal fixed tube 34. Similarly, apply glue on the outer wall of the package end 35 at end A (the application length is also half of the length of the package end 35), and pull the optical fiber 33 toward the direction of end B, so that half of the length of the package end 35 at end A and end B is inserted into the mouth of the metal fixed tube 34. By rotating the handwheel 31, the bevel gear transmission pair 29 drives the active roller 25 and the passive roller 26 to rotate, which facilitates 360-degree application and heating of glue to ensure the reliability of optical fiber assembly. The connection between the two package ends 35 and the metal fixed tube 34 is achieved, and the inner cavity of the metal fixed tube 34 is in a sealed state, which can effectively protect the optical fiber 33 therein (such as Figures 8 to 11shown).
