Description

Technical Field

[0001] This utility model relates to the field of fiber optic array manufacturing technology, specifically to a fiber optic array refraction angle tester. Background Technology

[0002] Fiber optic arrays, as key components in modern optical communication systems, are widely used in planar waveguide devices, dense wavelength division multiplexers, optical switches, and sensors. Fiber optic arrays achieve efficient and stable optical signal transmission and processing by precisely arranging multiple optical fibers on a substrate. To ensure that the quality and performance of fiber optic arrays meet production standards, a series of rigorous tests are typically required.

[0003] These tests include, but are not limited to, insertion loss, return loss, polarization-dependent loss, and environmental adaptability testing. Traditional testing methods primarily rely on precision instruments such as optical power meters, light sources, interferometers, and microscopes to measure various optical performance indicators of fiber optic arrays. Furthermore, they involve checking the fiber alignment accuracy to ensure that the positional deviation of each fiber within the array is within acceptable limits. While these testing methods can effectively assess the overall quality of fiber optic arrays, they often require complex equipment and specialized operating skills, and are time-consuming.

[0004] Currently, most fiber optic array inspection methods remain at the basic level of visual inspection and microscopic observation. This approach is not only inefficient but also susceptible to human error, making it difficult to guarantee the consistency and accuracy of results. Furthermore, traditional methods also fall short in detecting defects in fiber end-face quality and connections, failing to quickly and accurately identify minute flaws. Due to these limitations, existing inspection methods struggle to meet the demands of large-scale production and high-precision applications. Therefore, a more efficient, automated, and precise inspection tool is urgently needed to improve the production efficiency and product quality of fiber optic arrays. Laser angle measuring instruments, as a novel type of inspection equipment, hold promise for solving these problems and providing a more accurate and efficient inspection solution.

DETAILED DESCRIPTION

[0030] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the technical product is in use. They are only for the convenience of describing the technology and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the technology.

[0034] Please see Figures 1-5 The refraction angle tester for the fiber array includes a support base 1, a laser emitting component 2 and a fiber array fixing component 3 mounted on the support base 1, and an angle marking platform 4 placed outside the support base 1.

[0035] Among them, the support base 1 can be a metal plate commonly used in the prior art. The base is relatively heavy and its surface is provided with several mounting holes that allow external bolts to be inserted, which can serve as the basis for the stability and installation of the device.

[0036] The laser emitting assembly 2 includes a first fixing seat 21 on the support base 1 and a laser emitting device 22 on the first fixing seat 21. The fiber array fixing assembly 3 includes a second fixing seat 31 on the support base 1 and a clamping part 32 on the second fixing seat 31. The clamping part 32 can clamp the fiber array to be tested. The laser emitted by the laser emitting device 22 can irradiate the fiber array clamped on the clamping part 32. Then the fiber array can reflect the laser emitted by the laser emitting device 22 to the surface of the angle marking stage.

[0037] Because the fiber array fixing component 3 with internal cracks or defects has a significantly different laser reflection angle when the laser is irradiated on its surface compared to the laser angle reflected by a good fiber array, the operator can first install the good sample fiber array on the clamping part 32, and then turn on the laser emitting device 22 to record the laser position reflected on the angle marking stage 4. This provides a specific reference range for subsequent debugging of other fiber arrays.

[0038] Specifically, both the first fixed base 21 and the second fixed base 31 are provided with several adjustment parts 5. The laser emitting device 22 and the clamping part 32 are both mounted on the surface of the adjustment parts 5. The adjustment parts 5 can adjust the height and horizontal position of the laser emitting device 22 and the clamping part 32. The adjustment parts 5 include adjustment seats 51 and adjustment mechanisms 52 disposed between adjacent adjustment seats 51. The adjustment mechanism 52 can adjust the height and relative position between adjacent adjustment seats 51. The adjustment structure and the adjustment seats 51 are common adjustment structures on clamps in the prior art, often composed of threaded rods, gears, and racks. The operator can adjust the horizontal and vertical positions of the adjustment seats 51 by turning the knob to make appropriate fine adjustments to meet the testing requirements of fiber arrays of different sizes and models.

[0039] As shown in the figure, the clamping part 32 includes a clamping base 321, a clamping rod 322 disposed inside the clamping base 321, and an elastic connector 323 connecting the clamping base 321 and the clamping rod 322. The clamping base 321 has a through groove adapted to the clamping rod 322 and the elastic connector 323. Both ends of the clamping rod 322 extend to the outside of the clamping base 321. The surface of the clamping rod 322 is provided with a fixed support connected to the elastic connector 323. The surface of the clamping base 321 is provided with a slot for inserting the fiber array. One end of the clamping rod 322 extends into the slot. The elastic connector 323 can provide a force to the clamping rod 322 to move towards the inside of the slot. The operator can clamp the fiber array by pulling the clamping rod 322. The operation is quick and does not easily damage the surface of the fiber array.

[0040] Meanwhile, the laser emitting end of the laser emitting device 22 faces the slot provided on the surface of the clamping part 32. The angle marking platform 4 includes a marking base and a marking panel provided on the marking base. The marking panel has a scale on its surface.

[0041] In the description of this technology, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this technology based on the specific circumstances.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
