Description

Technical Field

[0001] This invention relates to the field of optical fibers, and more specifically to an optical fiber perpendicularity testing tool. Background Technology

[0002] Currently, there is no effective method for detecting the perpendicularity of the fiber end face before fiber optic splicing. Workers typically cut the fiber and then directly splice it; if the splice quality is poor, the spliced ​​portion is removed and the splicing is repeated until the quality meets requirements. If the perpendicularity of the fiber end face could be detected, the fiber optic splicing pass rate could be greatly improved, production costs reduced, and production efficiency increased.

[0003] Chinese patent CN202994107U discloses an optical fiber end-face perpendicularity checker. This device uses a light source system, objective lens, eyepiece, and transmission / reflection prism to determine the perpendicularity of the optical fiber end-face by measuring the degree to which the image of the optical fiber end-face deviates from the optical axis of the eyepiece. Chinese patent CN 214951179U also discloses an optical fiber end-face perpendicularity checker, which similarly uses a similar system to determine the perpendicularity of the optical fiber end-face. Neither of these devices clamps and secures the optical fiber, meaning that the fiber may not be perfectly perpendicular when inserted into the inspection channel. If the fiber end has a slight bend, even if the cross-section is perpendicular, there will still be a significant displacement of the image of the optical fiber end-face from the optical axis of the eyepiece. Furthermore, if the fiber fails to meet the standards after inspection, secondary trimming with other tools is required, wasting time on further inspection. Summary of the Invention

A first rubber wheel 73 is mounted on the first rotating shaft, a second rubber wheel 712 is mounted on the second rotating shaft, a third rubber wheel 74 is mounted on the third rotating shaft, and a fourth rubber wheel 714 is mounted on the fourth rotating shaft. The first rubber wheel is in contact with the second and third rubber wheels, the second rubber wheel is in contact with the first and fourth rubber wheels, the third rubber wheel is in contact with the first and fourth rubber wheels, and the fourth rubber wheel is in contact with the second and third rubber wheels. Each of the first, second, third, and fourth rubber wheels is provided with a insertion slot 715 that mates with the optical fiber. The four insertion slots cooperate to form a channel for accommodating the optical fiber.

[0023] Furthermore, the fiber optic mount is provided with a first mounting cavity S1 and a second mounting cavity S2. The first mounting cavity has a first communicating hole 79 that communicates with the insertion hole, and the second mounting cavity has a second communicating hole 710 that communicates with the insertion hole. The first and second rubber wheels are located in the first mounting cavity, and the third and fourth rubber wheels are located in the second mounting cavity. A driving mechanism is also installed in the first mounting cavity. The driving mechanism can drive the first rotating shaft to rotate, thereby causing the four rubber wheels to rotate, thus achieving the compression and fixation of the optical fiber.

[0024] Furthermore, the drive mechanism includes a drive shaft 76, which is rotatably connected in the first mounting cavity. A push wheel 77 is fixedly connected to the drive shaft, and a driven wheel 75 is fixedly connected to the first rotating shaft. The push wheel and the driven wheel cooperate with each other.

[0025] In at least one embodiment, the cutting mechanism includes a third mounting cavity S3 and a fourth mounting cavity S4. A fifth rotating shaft is rotatably mounted in the third and fourth mounting cavities. The fifth rotating shaft passes through the third and fourth mounting cavities. A cutting disc 92 and a first driven gear 93 are fixedly connected to the fifth rotating shaft. The cutting disc is located in the third mounting cavity, and the first driven gear is located in the fourth mounting cavity. A waste bin 97 is provided at the bottom of the third mounting cavity and is connected to the third mounting cavity. A sixth rotating shaft 94 is rotatably connected in the fourth mounting cavity. A second driven gear 95 is fixedly connected to the sixth rotating shaft. The first driven gear and the second driven gear cooperate with each other. A lower handwheel 96 is also fixedly connected to the sixth rotating shaft. A lower rectangular hole 961 for accommodating the lower handwheel is provided at the bottom of the fourth mounting cavity.

[0026] Furthermore, the cutting disc has a mounting hole 921 in the middle, an inner circular cutting blade 922 on the cutting disc, and a scraper 923 on one side of the inner circular cutting blade.

[0027] In at least one embodiment, the fiber optic socket is provided with a marking mechanism, which can be used to mark fibers whose perpendicularity conforms to the standard, so as to avoid confusion with other untested fibers.

[0028] Furthermore, the marking mechanism includes a liquid storage chamber 81, within which a pusher plate 82 is slidably fitted. A sliding hole is provided at the top of the liquid storage chamber, and a sliding rod 84 is slidably fitted within the sliding hole. One end of the sliding rod is fixedly connected to the pusher plate, and the other end passes through the optical fiber seat 6 and is connected to a lower pressure plate 85. A liquid outlet is provided at the bottom of the liquid storage chamber, and the liquid outlet communicates with the insertion hole. Correspondingly, heating wires 88 are provided on both sides of the insertion hole.

[0029] Furthermore, a transparent limiting piece 62 is provided on the side of the insertion hole near the objective lens mount. The transparent limiting piece can limit the fiber optic cable from being inserted too deeply.

[0030] In operation, when fixing the optical fiber, the handwheel is first rotated to create a channel for the four insertion slots to accommodate the fiber. After the fiber is inserted into the insertion hole 6 in the fiber optic socket, the handwheel is rotated again, causing the insertion slots of the four rubber wheels to rotate and move away from the fiber. This elastic deformation of the other parts of the rubber wheels relative to the fiber secures the fiber. Light emitted from the LED light passes through the transmission-reflecting prism and enters the objective lens along its optical axis. The light passing through the objective lens is reflected by the fiber's end face and then passes through the objective lens and the transmission-reflecting prism again before entering the eyepiece. The image of the fiber's end face can then be seen through the eyepiece.

[0031] When the fiber optic cross-section is detected as tilted, it needs to be further processed. At this point, the lower handwheel 96 is turned to rotate the cutting disc. When the disc is stationary, the fiber is positioned in the center of the inner circular cutting blade. As the disc rotates, the inner circular cutting blade contacts the fiber, cutting it. The scraper then moves the cut fiber cross-section into the waste bin. The process is repeated until the cross-section is perpendicular. The lower pressure plate is then manually moved, allowing colored dye from the storage chamber to enter the insertion hole. Heating wires then apply the dye to the fiber surface. After the fiber is removed, it displays a clear color mark, indicating that it meets the standard.

[0032] Except for the technical features described in the specification, all other technologies are known to those skilled in the art.
