Description

Technical Field

[0001] This application relates to the field of optical fiber testing technology, and in particular to a testing device for dual-headed optical fibers. Background Technology

[0002] After the fiber optic connector is manufactured, in order to improve and ensure the signal transmission quality, the end of the fiber optic head usually needs to be ground. After grinding, the end face is magnified and inspected again using an electronic inspection mirror to observe whether the end face is flat and whether there are scratches.

[0003] While existing testing equipment can perform testing and processing on fiber optic heads, the current method for testing fiber optic heads is usually to have the inspector insert the fiber optic connector into the corresponding position for observation. When testing dual-headed fibers, the fiber optic heads need to be loosened one by one before testing. The automatic alternation testing of two sets of fiber optic heads in a fixed state is not effective, resulting in excessive time spent by the inspector on the switching testing of dual-headed fibers, thus reducing the testing efficiency of dual-headed fibers on the testing equipment. Utility Model Content

[0006] The outer wall of the testing station is provided with a conversion mechanism, which includes a swing rod, a slide groove and a rotating rod;

A connecting groove is provided at the connection between the outer wall of the testing platform and the adjusting slider. A reciprocating groove is provided at the connection between the outer wall of the fixed plate and the sliding block.

[0008] By adopting the above technical solution, when the slider is adjusted by the swing rod, the two fiber heads of the optical fiber can be switched and detected alternately. At the same time, one of the fiber heads can be pre-disassembled and loosened after detection, thereby improving the effect of rapid unloading and replacement of the optical fiber after overall detection.

[0009] Preferably, the bottom of the testing platform is provided with a first servo motor that is fixedly connected to the rotation center of the swing arm, and a limit groove is provided at the connection between the outer wall of the swing arm and the adjusting slider.

[0010] By adopting the above technical solution, the adjusting slider can be easily slid alternately.

[0011] Preferably, there are two sets of limiting grooves, and the positions of the two sets of limiting grooves are equidistant from the rotation center of the swing rod.

[0012] By adopting the above technical solution, the adjustment slider can be conveniently limited during alternating sliding.

[0013] Preferably, a connecting groove is provided at the connection between the outer wall of the rotating rod and the sliding block, and the outer wall contour of the reciprocating groove is shaped like a square.

[0014] By adopting the above technical solution, the sliding block and the detection lens can be synchronously reciprocated and limited.

[0015] Preferably, the outer wall of the sliding block has a detection hole located at one end of the detection lens, and the detection hole is set on the extension and retraction trajectory of the adjusting slider.

[0016] By adopting the above technical solution, the detection head is inserted into the detection hole for alignment and detection.

[0017] Preferably, the outer wall of the adjusting slider is provided with a third servo motor, the output end of the third servo motor is fixedly connected to a threaded rod that is rotatably connected to the outer wall of the adjusting slider, the outer wall of the threaded rod is threadedly connected to a limiting block that is slidably connected to the outer wall of the adjusting slider, and a fixing groove is provided at the connection part between the outer wall of the adjusting slider and the limiting block.

[0018] By adopting the above technical solution, the effect of adjusting and positioning the fiber optic head can be achieved.

[0019] Preferably, the threaded rod is provided in two sets, and the two sets of threaded rods rotate in opposite directions.

[0020] By adopting the above technical solution, the effect of driving the two sets of limit blocks to slide relative to each other can be achieved.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By utilizing the rotation of the swing rod and the sliding of the sliding block, when the adjusting slider is positioned to limit the two sets of fiber optic heads, the rotation of the swing rod drives the adjusting slider to slide synchronously along the inner wall of the limiting groove and the sliding groove, causing the two sets of adjusting sliders to slide relative to each other. When the detection lens moves in a U-shape, the fiber optic head is switched to be detected, and the corresponding fiber optic head is switched to be detected. This allows for the detection of the two sets of fiber optic heads one by one while they are fixed at the same time, and the pre-loosening and disassembly movement after the detection of one set of fiber optic heads, thereby improving the overall speed of fiber optic replacement and detection.

[0023] 2. By using the centering movement of the limiting block, the positioning of fiber optic heads of different sizes can be adjusted when the detection device detects the double-headed fiber optic cable. The third servo motor is turned on and the rotation of the threaded rod drives the limiting block to slide along the inner wall of the fixed groove, so that the limiting block slides relative to the fiber optic head, thereby achieving the effect of clamping and limiting detection of the fiber optic head.

One end of the electric push rod 5 is fixedly connected to the pressure plate 6 slidably connected to the outer wall of the detection platform 1. An adjusting slider 3 is slidably connected to the outer wall of the detection platform 1. One end of the optical fiber body 2 is fixedly connected to an optical fiber head 4 placed on the outer wall of the adjusting slider 3. A fixing plate 7 is fixedly connected to the outer wall of the detection platform 1. A sliding block 8 is slidably connected to the outer wall of the fixing plate 7. The setting of the sliding block 8 can drive the detection lens 9 to adjust and slide synchronously with the sliding block 8. The outer wall of the sliding block 8 is provided with the detection lens 9.

[0032] The outer wall of the testing station 1 is provided with a conversion mechanism, which includes a swing rod 12, a slide 14 and a rotating rod 16.

[0033] The bottom of the testing platform 1 is rotatably connected to a swing rod 12 that is connected to the outer wall of the adjusting slider 3. The outer wall of the fixed plate 7 is provided with a second servo motor 15. By starting the second servo motor 15, the rotating rod 16 that is fixedly connected to the output end of the second servo motor 15 can be driven to rotate continuously. The output end of the second servo motor 15 is fixedly connected to a rotating rod 16 that is slidably connected to the outer wall of the sliding block 8. A connecting groove 17 is provided at the connection between the outer wall of the testing platform 1 and the adjusting slider 3. A reciprocating groove 18 is provided at the connection between the outer wall of the fixed plate 7 and the sliding block 8.

[0034] Reference Figure 3 The bottom of the testing platform 1 is equipped with a first servo motor 11 that is fixedly connected to the rotation center of the swing arm 12. A limit groove 13 is provided at the connection between the outer wall of the swing arm 12 and the adjusting slider 3, which is conducive to achieving the effect of synchronously limiting the sliding of the adjusting slider 3 through the setting of the limit groove 13.

[0035] Reference Figure 3 The limiting groove 13 is provided in two sets. The positions of the two sets of limiting groove 13 are equidistant from the rotation center of the swing rod 12. This is beneficial to achieve the effect of driving the two sets of adjusting sliders 3 to slide alternately by setting two sets of limiting groove 13 with positions equidistant from the rotation center of the swing rod 12.

[0036] Reference Figure 3 A connecting groove 17 is provided at the connection between the outer wall of the rotating rod 16 and the sliding block 8. The outer wall contour of the reciprocating groove 18 is U-shaped, which is conducive to achieving the effect of synchronously limiting the sliding of the detection lens 9 through the U-shaped setting of the outer wall contour of the reciprocating groove 18.

[0037] Reference Figure 1The outer wall of the sliding block 8 is provided with a detection hole 10 located at one end of the detection lens 9, and the detection hole 10 is set on the extension and retraction trajectory of the adjusting slider 3. This facilitates the alignment accuracy between the detection lens 9 and the fiber optic head 4 by setting the detection hole 10 on the extension and retraction trajectory of the adjusting slider 3.

[0038] Reference Figure 4 The outer wall of the adjusting slider 3 is provided with a third servo motor 19. The output end of the third servo motor 19 is fixedly connected to a threaded rod 20 that is rotatably connected to the outer wall of the adjusting slider 3. The outer wall of the threaded rod 20 is threadedly connected to a limiting block 21 that is slidably connected to the outer wall of the adjusting slider 3. A fixing groove 22 is provided at the connection between the outer wall of the adjusting slider 3 and the limiting block 21, which is conducive to achieving the effect of conveniently limiting and fixing the fiber optic head 4 through the setting of the limiting block 21.

[0039] Reference Figure 4 The threaded rod 20 is provided in two sets, and the two sets of threaded rods 20 rotate in opposite directions. This is beneficial to achieve the effect of driving the two sets of limit blocks 21 to slide relative to each other by setting two sets of threaded rods 20 with opposite rotation directions.

[0040] The working principle of this detection device for dual-headed optical fibers is as follows: When the adjusting slider 3 limits the placement of the two sets of optical fiber heads 4, the rotation of the swing rod 12 drives the adjusting slider 3 to slide synchronously along the inner wall of the limiting groove 13 and the sliding groove 14, causing the two sets of adjusting sliders 3 to slide relative to each other. When the detection lens 9 moves in a U-shape, the optical fiber head 4 is switched to be detected, and the corresponding detection of the optical fiber head 4 is performed. It can detect the two sets of optical fiber heads 4 one by one while fixing them at the same time, and perform a pre-loosening and disassembly movement after detecting one set of optical fiber heads 4, thereby improving the overall rapid replacement and detection effect of the optical fiber.

[0041] When the double-headed optical fiber is tested by the testing device, the positioning of the optical fiber head 4 of different sizes is adjusted. The third servo motor 19 is turned on and the threaded rod 20 rotates, which drives the limiting block 21 to slide along the inner wall of the fixed groove 22, so that the limiting block 21 slides relative to each other, thereby achieving the effect of clamping and limiting the detection of the optical fiber head 4.

[0042] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
