Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical fiber testing equipment technology, and more specifically, to an optical fiber angle testing device. Background Technology
[0002] Optical fiber, also known as optical waveguide fiber, is an advanced transmission medium that uses the principle of total internal reflection to transmit optical signals in a slender, flexible, and transparent medium. It is typically made of high-purity glass or special plastics through precision drawing, possessing extremely high light transmittance and extremely low signal attenuation. The structure of an optical fiber generally consists of a core and a cladding. The core is the main channel for optical signal transmission; its refractive index is higher than that of the cladding, causing total internal reflection at the interface between the core and cladding, thus propagating along the fiber axis. This transmission method gives optical fibers a series of advantages, including high transmission speed, large capacity, low attenuation, long transmission distance, and strong anti-interference capabilities.
[0003] In the field of optical fiber communication, the end-face angle of an optical fiber is a crucial parameter that directly affects the transmission efficiency and performance of the fiber. Therefore, it is necessary to test the end-face angle of the optical fiber during production and use. The traditional method for testing the end-face angle of an optical fiber usually involves installing each individual optical fiber onto a fixture, then emitting a laser beam to the end face of the fiber using a laser generator, and observing the position of the light spot reflected onto a scale plate to determine the end-face angle of the fiber. Since each individual optical fiber needs to be tested, and the fiber needs to be installed onto the fixture before each test and removed from the fixture after the test, the testing process is cumbersome and time-consuming, and cannot meet the testing requirements of large-scale optical fiber production.

[0018] 3. Beneficial effects
[0019] Compared with existing technologies, this utility model provides an optical fiber angle testing device, which has the following features:
[0020] Beneficial effects:
[0021] This fiber optic angle testing device uses a multi-fiber fixing mechanism to secure multiple optical fibers. This mechanism is mounted on a connecting rod block. A laser generator emits a laser beam onto the end face of the fiber, which is then reflected onto a scale plate to detect the end face angle. Simultaneously, a stepper motor controls a transmission worm gear to rotate a fixed number of times at a fixed frequency. This, in turn, drives a transmission gear to rotate a fixed amplitude, moving a transmission gear plate a fixed distance. This allows the optical fibers in the multi-fiber fixing mechanism to step-by-step engage with the laser beam emitted by the laser generator, thus completing the detection of the end face angles of multiple optical fibers. By pre-fixing a large number of optical fibers within multiple sets of multi-fiber fixing mechanisms, the device only needs to continuously replace these mechanisms during the cross-sectional angle testing of a large number of optical fibers. Compared to the traditional method of frequently removing and installing fibers from fixtures, this device allows for the simultaneous testing and replacement of multiple fibers, significantly simplifying the cross-sectional angle testing process for large quantities of optical fibers and thus greatly improving the testing efficiency.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0029] Example:
[0030] Please see Figures 1-4 A fiber optic angle testing device, comprising:
[0031] A base plate 1 is fixedly connected to a mounting plate 2 on its top. A dial plate 4 is fixedly connected to one outer surface of the mounting plate 2. A laser generator 3 is fixedly installed on the other outer surface of the mounting plate 2. The laser generator 3 penetrates the mounting plate 2.
[0032] Stepper control box 6 is fixedly connected to the top of base plate 1. Two support rods 11 are fixedly connected to the inner walls of both sides of stepper control box 6. Transmission gear plate 10 is slidably sleeved on the two support rods 11. Connecting rod block 12 is fixedly connected to the top of transmission gear plate 10. Transmission gear 9 is rotatably connected between the inner walls of both sides of stepper control box 6. Transmission gear 9 meshes with transmission gear plate 10.
[0033] The stepper drive assembly is located on one outer surface of the stepper control box 6, and
[0034] The multi-fiber fixing mechanism 5 includes a lower clamping plate 501, an upper clamping plate 502, a threaded rod 503, and a connecting bolt 504. The connecting bolt 504 is fixedly connected to the bottom of the lower clamping plate 501 and is threadedly connected to the connecting rod block 12. The threaded rod 503 is rotatably connected to the top of the lower clamping plate 501, and the upper clamping plate 502 is threadedly connected to the threaded rod 503.
[0035] In a specific embodiment of this utility model, multiple placement slots are provided on both the lower clamping plate 501 and the upper clamping plate 502. Multiple optical fibers are placed into the multiple placement slots of the lower clamping plate 501. By rotating the threaded rod 503, the upper clamping plate 502 is moved, so that the lower clamping plate 501 and the upper clamping plate 502 fix the multiple optical fibers. By screwing the connecting bolt 504 into the connecting rod block 12, the multi-fiber fixing mechanism 5 is fixedly installed on the connecting rod block 12. By controlling the laser generator 3 to start, the laser emitted by the laser generator 3 hits the optical fiber fixed on the multi-fiber fixing mechanism 5. By reflecting the light spot on the scale plate 4, the cross-sectional angle of the optical fiber is tested to see if it meets the requirements. At the same time, the stepper drive component continuously controls the transmission gear 9 to rotate at a fixed frequency and a fixed amplitude, driving the transmission gear plate 10 to move a fixed distance, so that the multi-fiber... The optical fibers on the fiber fixing mechanism 5 will step in coordination with the laser beam emitted by the laser generator 3 to complete the detection of the end face angles of multiple optical fibers. Moreover, in actual practice, there is more than one set of multi-fiber fixing mechanisms 5. By fixing the optical fibers in multiple sets of multi-fiber fixing mechanisms 5 in advance, and by screwing the connecting bolts 504 on each set of multi-fiber fixing mechanisms 5 into the connecting rod block 12, in the process of detecting the end face angles of a large number of optical fibers, it is only necessary to continuously replace the multi-fiber fixing mechanisms 5 to detect a large number of optical fibers. In the process of detecting the end face angles of a large number of optical fibers, compared with the traditional method of frequently removing and installing optical fibers from the fixture, it is possible to detect multiple optical fibers at one time and replace multiple optical fibers at one time, which greatly simplifies the operation process of detecting the end face angles of a large number of optical fibers, thereby significantly improving the detection efficiency of a large number of optical fibers.
[0036] Specifically, the stepper drive assembly also includes a drive control box 7, a transmission worm gear 13, and a transmission worm 14. The drive control box 7 is fixedly connected to one outer surface of the stepper control box 6. The transmission worm 14 is rotatably connected between the two inner walls of the drive control box 7. The transmission worm gear 13 is rotatably connected between the front and rear inner walls of the drive control box 7. The transmission worm gear 13 is fixedly connected to the transmission gear 9, and the transmission worm gear 13 is meshed with the transmission worm 14.
[0037] In this embodiment, by controlling the transmission worm 14 to rotate a fixed number of turns, the transmission worm wheel 13 is driven to rotate a fixed angle, which in turn drives the transmission gear 9 to rotate a fixed angle, thereby causing the transmission gear plate 10 to move a fixed distance.
[0038] Specifically, the stepper drive assembly also includes a stepper motor 8, the output end of which is fixedly connected to the transmission worm gear 14.
[0039] In this embodiment, by controlling the start of the stepper motor 8, the rotation of the transmission worm gear 14 can be controlled to a fixed range.
[0040] Specifically, the multi-fiber fixing mechanism 5 also includes a fixing rod 505, which is fixedly connected to the top of the lower clamping plate 501, and the upper clamping plate 502 is slidably sleeved on the fixing rod 505.
[0041] In this embodiment, the fixing rod 505 keeps the relative movement between the upper clamping plate 502 and the lower clamping plate 501 stable.
[0042] Specifically, the fixing rod 505 is made of stainless steel.
[0043] In this embodiment, the surface of the fixing rod 505 is smooth and has low friction, which makes the upper clamping plate 502 move with less resistance on the fixing rod 505.
[0044] Specifically, both support rods 11 are made of stainless steel.
[0045] In this embodiment, the two support rods 11 are corrosion resistant and their surface quality can be guaranteed even when in contact with the external environment.
[0046] Working principle: Multiple optical fibers are placed into the various slots of the lower clamping plate 501. Rotating the threaded rod 503 moves the upper clamping plate 502, fixing the optical fibers in place. Connecting bolts 504 are screwed into the connecting rod block 12, fixing the multi-fiber fixing mechanism 5 onto the connecting rod block 12. The laser generator 3 is activated, emitting a laser beam that strikes the optical fibers fixed in the multi-fiber fixing mechanism 5. The reflected light spot on the scale plate 4 tests whether the cross-sectional angle of the optical fiber meets the requirements. Simultaneously, the stepper motor 8 drives the transmission worm gear 14 to rotate a fixed number of times at a fixed frequency, rotating the transmission worm wheel 13 by a fixed angle. This continuously controls the rotation of the transmission gear 9 by a fixed amplitude, moving the transmission gear plate 10 a fixed distance. This ensures that the optical fibers in the multi-fiber fixing mechanism 5 stepwise coordinate with the laser beam emitted by the laser generator 3, thus completing the process. The detection of the end face angles of multiple optical fibers is achieved by pre-fixing a large number of optical fibers in multiple sets of multi-fiber fixing mechanisms 5. By screwing the connecting bolts 504 on each set of multi-fiber fixing mechanisms 5 into the connecting rod block 12, the detection of the end face angles of a large number of optical fibers only requires continuously replacing the multi-fiber fixing mechanisms 5. This eliminates the need for the traditional method of frequently removing and installing optical fibers from the fixture, enabling the simultaneous detection and replacement of multiple optical fibers. This significantly simplifies the operation process for detecting the end face angles of a large number of optical fibers, thereby significantly improving the detection efficiency. The control method of this invention is achieved through manual start and stop switches. The wiring diagram of the power components and the supply of power are common knowledge in the field. Furthermore, since this invention is primarily used to protect mechanical devices, the control method and wiring arrangement will not be explained in detail here.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
