[0026] Example

[0027] like Figure 1 , 2 As shown, the fiber optic parallel tape fixture of this embodiment includes a base plate 1, a fiber optic guide assembly 2, a fiber optic pre-aggregator 3, and a parallel tape channel 4. The parallel tape channel 4 is mounted on the upper end of the base plate 1. The fiber optic guide assembly 2 is movably mounted on the upper end of the base plate 1 and can move closer to or away from one end of the parallel tape channel 4. The fiber optic pre-aggregator 3 is mounted on the upper end of the base plate 1 and is located between the fiber optic guide assembly 2 and the parallel tape channel 4, and is close to one end of the parallel tape channel 4. The parallel tape channel 4 is provided with a guide and conveyor assembly.

[0028] The optical fiber parallel lacing tool jig in the embodiment can adjust the amplitude of the bending of the plurality of optical fibers when entering the optical fiber pre-assembler 3 by adjusting the distance between the optical fiber guide assembly 2 and the parallel lacing channel 4 (for example, the closer the distance, the greater the bending amplitude, and the farther the distance, the smaller the bending amplitude), and the design of the optical fiber pre-assembler 3 can make a transition to the bending of the optical fiber, so that the optical fiber can better enter the relatively narrow parallel lacing channel 4. In addition, the guiding and conveying assembly in the parallel lacing channel 4 is also conducive to the passing of the optical fiber through the parallel lacing channel 4, and is not prone to jamming and other phenomena. Overall, the structure is reasonably designed, and through the position adjustment of the optical fiber guide assembly and the design of the optical fiber pre-assembler, the plurality of optical fibers can be smoothly and stably transitioned into the parallel lacing channel and the parallel lacing, the damage caused by the large bending difference in the parallel lacing process is reduced, and at the same time, the normal conveying of the optical fiber parallel lacing can also be ensured.

[0029] As a preferred embodiment, as shown in Figure 4 As shown (the dashed lines in the figure represent the internal channels and holes), one end of the optical fiber pre-assembler 3 near the parallel lacing channel 4 is provided with a first channel 31 in the shape of a rectangular solid, and the other end of the parallel lacing channel 4 is provided with a plurality of independent and tapered fiber inlet holes 32, and the tapered tip of the fiber inlet hole 32 is connected to the first channel 31.

[0030] In the above embodiment, the front end of the optical fiber pre-assembler 3 is designed with a plurality of "divergent" distributed fiber inlet holes 32, which are conducive to the bending of the optical fiber at a small amplitude and oblique angle into the first channel 31, and then smoothly into the butt joint parallel lacing channel 4 through the quality first channel 31, ensuring that the optical fiber has formed a well-shaped "strip-shaped bundle" after passing through the optical fiber pre-assembler 3, and is easy to pass through the parallel lacing channel 4 for parallel lacing.

[0031] In the embodiment, the optical fiber guide assembly 2 includes a plurality of wheel frames 21, a plurality of guide wheels 22, and a sliding base 23. The sliding base 23 is slidably mounted on the upper end of the bottom plate 1, a plurality of wheel frames 21 are arranged side by side on the upper end of the sliding base 23, and a plurality of guide wheels 22 are respectively and correspondingly and rotatably mounted on one side of the plurality of wheel frames 21.

[0032] As a preferred embodiment, the wheel frame 21 includes a screw rod 211, a locking nut 212, and a mounting block 213. The upper end of the sliding base 23 is provided with a plurality of screw holes corresponding to the screw rod 211. The screw rod 211 is vertically arranged, and the lower end is threadedly mounted in the corresponding screw hole. The locking nut 212 is threadedly combined with the lower end of the screw rod 211 and can be screwed to abut or separate from the upper end of the sliding base 23. The mounting block 213 is fixed to the screw rod 211, and the guide wheel 22 is mounted on the side end of the mounting block 213 through an axle.

[0033] In the above embodiment, the rotation angle of the screw rod 211 can be adjusted by loosening the locking nut 212, that is, the deflection angle of each guide wheel 22 is adjusted, and the adjustment is locked by the locking nut 212. The adjustment of the deflection angle of the guide wheel 22 facilitates the bending and conveying of the optical fiber.

[0034] As a preferred embodiment, the bottom plate 1 is provided with a straight strip-shaped sliding rail, the lower end of the sliding base 23 is provided with a sliding groove matched with the sliding rail, and the sliding base 23 is embedded on the sliding rail through the sliding groove. The side end of the sliding base 23 is provided with a threaded tightening bolt, and the tightening bolt is used to screw to abut or separate from the sliding rail.

[0035] In the above embodiment, the sliding base 23 can be moved along the sliding rail by loosening the tightening bolt, so as to adjust the distance between the optical fiber guide assembly 2 and the ribbon channel 4. After adjustment, the tightening bolt is tightened again.

[0036] In the embodiment, as shown in Figure 3 the lower groove 41 and the upper cover 42 of the ribbon channel 4 are of a rectangular parallelepiped type. The lower groove 41 is provided with a rectangular slot, the upper end of which is open and penetrates through both ends of the lower groove 41. The upper cover 42 is detachably mounted on the open end of the lower groove 41. The split design of the ribbon channel 4 facilitates the entry of the optical fiber.

[0037] In the embodiment, the upper end edges of both sides of the lower groove 41 are provided with outwardly turned first flanges, and the both sides of the upper cover 42 are assembled with the first flanges through penetrating bolts.

[0038] As a preferred embodiment, the bottom wall of the lower groove 41 is rotatably provided with a plurality of first rubber rollers 411 between the two sides thereof. The plurality of first rubber rollers 411 are distributed between the two ends of the lower groove 41. The lower end of the upper cover 42 is provided with a frame which can elastically float up and down. A plurality of second rubber rollers 412 are arranged in the frame and are parallel to the first rubber rollers 411. The plurality of second rubber rollers 412 are distributed between the two ends of the upper cover 42 and extend into the lower groove 41.

[0039] In the above embodiment, after a plurality of optical fibers enter the ribbon channel 4 side by side, the upper parts of the plurality of first rubber rollers 411 located below cooperate with the elastic floating of the second rubber rollers 412 on the frame, so that the optical fibers can be "clamped" between the first rubber rollers 411 and the second rubber rollers 412 to a certain extent. After the optical fibers come out of the other end of the ribbon channel 4, a "ribbon" with relatively regular arrangement is formed, which facilitates the subsequent good performance of the ribbon coating or dispensing process.

[0040] In the embodiment, the upper end of the frame is provided with a plurality of guide columns 413 penetrating through the upper cover 42, the upper end of the guide column 413 is provided with a limiting head 414, and the frame is connected with the upper cover 42 through an elastic element 415. The elastic element 415 keeps downward elastic force, so that the second rubber roller 412 on the frame can be close to the first rubber roller 411, thereby forming a "clamping" effect on the optical fiber passing between the two.

[0041] In the embodiment, the elastic element 415 is a spring, and the limiting head 414 is a nut detachably mounted on the upper end of the guide column 413. The nut is removed to facilitate disassembly of the entire frame.
