An optical fiber manufacturing fusion splicer

Abstract

The present invention discloses an optical fiber fusion splicer, which includes a frame body. Four grooves are provided at the top of the frame body. Through the mutual cooperation among structures such as a magnifying glass, a fusion joint, a limiting ring, and a Z-shaped plate, it is possible to move the cover plate upward, limit the cover plate through a threaded rod and a vertical rod, and then place the processed optical fiber in the groove inside the limiting ring. Five optical fibers can be placed at a time, which means that after two of the optical fibers are fused, by rotating the limiting ring, the optical fibers in the adjacent grooves can be aligned with the fusion joint to facilitate continuous fusion. The operator can choose to use a horizontal or vertical fusion joint for work according to his own habit. If a horizontal fusion joint is used, first move the limiting plate downward. The limiting plate drives the limiting elastic rod to move inside the V-shaped tube, and the Z-shaped plate can jack up the adjacent fusion joint. By rotating the screw into the adjacent threaded hole, the position of the fusion joint can be limited.

[0042] Working principle: When the device starts working, the operator first rotates and takes out the threaded rod 7, and then moves the cover plate 2 upward. The cover plate 2 drives the vertical rod 5 to move through the fixed plate 4. When the cover plate 2 moves to the appropriate position, the threaded rod 7 is rotated to the inside of the threaded rod 7, and the position of the cover plate 2 is limited. Then the operator selects one of the movable plates 15, and first adjusts the swing plate 16, and moves the swing plate 16 upward. The swing plate 16 drives the adjacent movable plate 15 to move upward. When the movable plate 15 moves to the appropriate position, the operator picks up the U-shaped plate 3, passes the U-shaped plate 3 through the surface of the frame 1, and moves the U-shaped plate 3 to the bottom of the adjacent movable plate 15. The U-shaped plate 3 can support the movable plate 15. The operator takes out the optical fiber and passes the optical fiber through the adjacent The blade 27 and the ring 22, the scale 17 can facilitate the operator to observe the length that needs to be cut, and then the operator moves the adjacent blades 27 to the center, the blade 27 drives the cross plate 28 to move, the blade 27 drives the connecting elastic rod 26 to stretch, the blade 27 clamps the surface of the optical fiber, the operator pulls the optical fiber, peels off the outer skin of the optical fiber, and then loosens the blade 27, places the exposed part of the optical fiber inside the elastic ring 23, pinches the elastic ring 23, and the elastic ring 23 drives the towel 42 to clean the exposed part of the optical fiber. When the towel 42 needs to be taken out, the elastic U-shaped rod 43 is slightly opened, and the elastic U-shaped rod 43 drives the insertion rod 44 to move, and the insertion rod 44 is taken out from the inside of the towel 42 and the elastic ring 23, and the towel 42 can be taken out. When the cleaning is completed, the optical fiber is placed inside the ring 22 again, and the optical fiber is cut according to the operator's habit. At this time, the blade 27 is moved to the center until the blade 27 cuts the optical fiber. In this process, the operator can repeat the operation to perform preliminary processing on multiple optical fibers. After the preliminary processing of multiple optical fibers is completed, the optical fibers are passed through the limiting ring 50 inside the adjacent connecting block 31 in sequence. Five optical fibers can be placed inside the limiting ring 50. At this time, the operator can choose to stand in different positions to weld the optical fibers. The horizontal operation or the vertical operation can be selected. The selection of the horizontal operation or the vertical operation can be determined according to the operator's position. At this time, the operator is defaulted to stand at the front side of the device and select the two longitudinal welding joints 33 for operation to weld the optical fibers. Place it inside the two horizontal connecting blocks 31, and then move the limit plates 36 on the left and right sides downward, the limit plates 36 drive the screws 37 to move downward, the limit plates 36 drive the limit elastic rods 38 to move, the limit elastic rods 38 drive the Z-shaped plate 40 to move through the V-shaped tube 39, the Z-shaped plate 40 drives the adjacent fusion joints 33 to move upward, the fusion joints 33 drive the adjustment elastic rods 41 to stretch, and the fusion joints 33 gradually move away from the moving block 35. At this time, move the connecting blocks 31 on the left and right sides, the connecting blocks 31 drive the movable block 30 to move, and the movable block 30 moves on the surface of the connecting rod 29. The operator can observe the degree of bonding of the two adjacent optical fibers through the transparent plate on the top of the cover plate 2 and the magnifying glass 12. When the bonding of the two adjacent optical fibers is completed,The starting device, the fusion joint 33 fuses two adjacent optical fibers. After completing one optical fiber fusion, the limiting ring 50 is rotated, and the remaining optical fibers inside the limiting ring 50 are bonded and brought close to the fusion joint 33, so that multiple optical fibers can be fused. The elastic plate 49 can limit the position of the moving block 35. After the fusion is completed, the optical fiber is placed between two adjacent connecting U-shaped rods 18. The heat shrinkable tube pre-sleeved on the surface of the connecting U-shaped rod 18 is moved on the surface of the connecting U-shaped rod 18, and the heat shrinkable tube is moved to the surface of the optical fiber. Then the heater 10 is moved downward, and the heater 10 drives the spring 11 to stretch, and the heater 10 can shrink the heat shrinkable tube, and the heat shrinkable tube wraps and protects the fusion joint of the optical fiber.,
