Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber testing, in particular to an optical fiber warpage traceability testing device. Background Art

[0002] Communication optical cables are one of the infrastructure for global informatization construction. Among them, optical fiber ribbon cables are widely used in access network systems. When using a passive alignment fusion welding machine or an active alignment batch fusion welding machine during the installation and construction of optical fiber ribbon cables, the warpage value of the optical fiber is an important parameter affecting the connection loss. Therefore, it is necessary to measure the warpage value of the uncoated optical fiber to make the fusion loss of the optical fiber ribbon meet the relevant requirements of the communication system.

[0003] The side-view microscopy technique measures the radius of curvature of an uncoated optical fiber by determining the deviation generated when the unsupported optical fiber end rotates around the fiber axis. However, the warpage value of the optical fiber tested by existing commercial instruments cannot be traced, that is, it is impossible to determine whether the result tested by the instrument is accurate and the magnitude of the deviation.

[0004] Therefore, it is necessary to develop an optical fiber warpage traceability testing device to solve the above problems. Content of the Utility Model

The stepped structure on the mounting block 14 includes a third mounting surface 19, a sixth mounting surface 22, and a fourth mounting surface 20 that are connected in sequence. The stepped structure on the test fixture 15 includes a first mounting surface 16, a fifth mounting surface 23, and a second mounting surface 17 that are connected in sequence.

The optical fiber is arranged coaxially with the rotating platform 13. When it is necessary to fix the height of the test fixture 15, the top of the test fixture 15 can be made to press against the inner top of the mounting block 14. The mounting block 14 can be understood to originally be a cylindrical structure, and after a horizontal piece is cut off from the lower part of the mounting block 14, it forms an L-shaped structure.

[0039] As Figure 1 shown, in some embodiments, the vertical moving mechanism includes a lower mounting plate 3, an upper mounting plate 6, two guide rods 4, a screw rod 5, and a handwheel 7. The upper mounting plate 6 is installed above the lower mounting plate 3. The lower mounting plate 3 and the upper mounting plate 6 are both fixedly positioned. The upper mounting plate 6 and the lower mounting plate 3 are parallel to each other. The two guide rods 4 and the screw rod 5 are parallel to each other, and the two ends of the guide rod 4 are respectively connected to the lower mounting plate 3 and the upper mounting plate 6. The two ends of the screw rod 5 are respectively rotatably installed on the lower mounting plate 3 and the upper mounting plate 6 through bearings. The upper end of the screw rod 5 passes through the upper mounting plate 6 and is connected to the lower end of the handwheel 7. Two mutually parallel limit holes and a threaded hole are vertically provided on the sliding block 8. The two guide rods 4 are slidably placed in the two limit holes, and the screw rod 5 is in threaded engagement with the threaded hole.

[0040] As Figure 1 shown, the vertical moving mechanism further includes a vertically arranged back plate 21. The two ends of the back plate 21 are respectively connected to the upper mounting plate 6 and the lower mounting plate 3.

[0041] As Figure 1 and 6 shown, the vertical moving mechanism includes a locking buckle 9 and a handle bolt 10. The first end of the locking buckle 9 is fixed on the upper mounting plate 6. A clamping groove is vertically provided at the second end of the locking buckle 9. A threaded hole is horizontally penetrated on the first side of the clamping groove. The handle bolt 10 is in threaded engagement with the threaded hole. The end of the handle bolt 10 is limited and rotatably installed inside the second side of the clamping groove. The upper end of the screw rod 5 passes upward through the clamping groove.

[0042] As shown Figure 1 in the figure, the optical fiber warpage traceability test equipment further includes a base 2 and four height-adjustable feet 1. The lower mounting plate 3 is mounted above one end of the base 2, and the four feet 1 are mounted below the four corners of the base 2.

[0043] As shown Figure 1 in the figure, the optical fiber warpage traceability test equipment further includes a vertical plate 11 and a horizontal plate 12. The upper end of the vertical plate 11 is connected to the first end of the horizontal plate 12. The vertical plate 11 is perpendicular to the horizontal plate 12. The horizontal plate 12 is horizontally arranged. The vertical plate 11 is connected to one side of the sliding block 8. An installation hole is vertically arranged on the horizontal plate 12. The rotating platform 13 is mounted above the horizontal plate 12, and the rotating shaft of the rotating platform 13 passes downward through the installation hole and is connected to the top of the installation block 14.

[0044] Working principle:

[0045] When the present application is working, place the level on the top of the rotating platform 13, and adjust the heights of the four feet 1 to make the rotating platform 13 reach a horizontal state. Correspondingly, the base 2, the upper mounting plate 6, and the horizontal plate 12 are all in a horizontal state;

[0046] By rotating the handwheel 7, the rotation of the screw rod 5 can be realized. Also, because the screw rod 5 is in threaded cooperation with the sliding block 8, the vertical position of the screw rod 5 remains unchanged, and the sliding block 8 is in limit sliding cooperation with the guide rod 4, so the sliding block 8 moves vertically. Correspondingly, the rotating platform 13, the installation block 14, and the test fixture 15 mounted on the sliding block 8 all move vertically, and the optical fiber also moves vertically; when the vertical position of the optical fiber is determined, then rotate the handle bolt 10. Because the handle bolt 10 is in threaded cooperation with the screw hole on the clamping groove, and the end of the handle bolt 10 is limited and rotatably mounted inside the second side of the clamping groove, the two sides of the clamping groove can be pulled closer to clamp the screw rod 5, so that the vertical position of the optical fiber will not change;

[0047] By adjusting the rotating platform 13, the installation block 14, the test fixture 15, and the optical fiber clamped on the test fixture 15 can be circumferentially rotated; the rotating platform 13 is a fine-tuning type rotating platform 13.

[0048] When specifically conducting the test, it is necessary to cooperate with an optical projector. The optical projector is placed on one side of the optical fiber and projects. On the other side, the projection blocked by the optical fiber is received. By cooperating with manual measurement or machine vision analysis, the deviation of the optical fiber end from the center position can be measured to obtain the maximum deviation distance, realizing the traceability of the optical fiber test; the setting of the vertical moving mechanism during the measurement process is to move the test fixture 15 and the optical fiber clamped on the test fixture 15 up and down to cooperate with the projection height of the optical projector. During the measurement, the optical fiber needs to be rotated at least 360° through the operation of the rotating platform 13.

[0049] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
