Description

Technical Field

[0001] This utility model relates to the field of FA fiber array cleaning, and in particular to a fixture for FA fiber array cleaning. Background Technology

[0002] FA fiber arrays are arrays formed by mounting a bundle of optical fibers or a fiber ribbon on a V-groove substrate at specified intervals. During use, the end faces of the fiber array are easily contaminated with dust, oil, and other pollutants, which can lead to loss of optical communication signals. Therefore, fiber arrays need to be cleaned after a period of use to restore their performance. During the cleaning process, in order to maintain the stable position and shape of the FA fiber array, facilitate the cleaning operation, and avoid unnecessary damage to the optical fibers, clamps are required to hold and fix the FA fiber array.

[0003] While existing clamps can stably hold and fix FA fiber arrays, when performing multi-faceted cleaning of FA fiber arrays, it is necessary to disassemble and re-clamp the FA fiber arrays. It is also inconvenient to clamp and clean multiple FA fiber arrays at the same time, which increases the workload and can easily affect work efficiency. In addition, sometimes there is a lot of dust accumulated on the outer surface of the FA fiber array. Direct wiping and cleaning can easily cause a lot of friction between the dust and the FA fiber array, which may cause damage to the FA fiber array due to friction. Moreover, the residual organic solvents or small amounts of moisture after cleaning may affect the subsequent optical performance of the fiber array. Natural drying of FA fiber arrays can also affect work efficiency. Summary of the Invention

[0004] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a fixture for cleaning FA fiber arrays to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fixture for cleaning FA fiber arrays, comprising a fixed frame, a flip frame, a positioning frame, an air jet head, a take-up and take-down groove, a groove, a support plate, and a limiting protrusion. The flip frame is rotatably installed inside the fixed frame, and two or more positioning frames are detachably installed inside the flip frame. Several air jet heads are installed inside the fixed frame, with the air outlet of the air jet head facing the bottom of the positioning frame. The air jet head is used to spray nitrogen gas, which pre-cleans the FA fiber array inside the fixed frame and also dries the cleaned FA fiber array.

[0006] The positioning frame is a hollow structure that runs vertically through the frame.

[0007] The positioning frame is equipped with two sets of mutually symmetrical limiting components, which are used to provide limiting for the FA fiber array;

[0008] The limiting component includes a take-up slot and a groove respectively opened on the bottom end face and inner wall of the positioning frame, a support plate rotatably installed in the take-up slot, and a clamping component set in the groove for clamping the FA fiber array. A limiting protrusion is provided in the take-up slot. When the support plate is in the extended state, it fits against the limiting protrusion, so that the support plate is in an inclined state when it extends from the take-up slot.

[0009] The free end of the support plate extends to the inner bottom of the positioning frame. The support plate has an L-shaped plate structure, and its corners exhibit a continuous S-shaped bending transition.

[0010] Preferably, the clamping assembly includes a clamp plate slidably installed in the groove for clamping the FA fiber array, an electromagnet installed in the groove and facing the clamp plate, the clamp plate being connected to the inside of the groove by a spring, and the clamp plate being made of stainless iron.

[0011] Preferably, the magnetic attraction force of the electromagnet on the clamping plate when energized is greater than the elastic force of the spring.

[0012] Preferably, a protective pad is provided on the outer end face of the clamping plate and the free end of the support plate.

[0013] Preferably, the protective pad is one of a silicone sheet, a rubber sheet, or a flexible Teflon sheet.

[0014] Preferably, a servo motor is mounted on the side surface of the fixing frame, and the output shaft of the servo motor is connected to the flipping frame.

[0015] Preferably, the upper and lower end faces of the positioning frame are flush with the upper and lower end faces of the flipping frame, respectively.

[0016] The beneficial effects of this utility model are:

[0017] This invention uses nitrogen gas ejected from a jet nozzle to remove surface dust, achieving pre-cleaning of the FA fiber array before wiping, reducing frictional damage during wiping. After one side of the FA fiber array is cleaned, the flipping frame flips within the fixed frame, causing the FA fiber array to rotate so that the uncleaned side faces upwards. Simultaneously, the support plate rotates downwards under gravity and is stored in the storage slot, reducing the obstruction of the FA fiber array by the support plate and facilitating the cleaning of the other side of the FA fiber array. With the cleaned side of the FA fiber array facing downwards, it can then continue to be dried by blowing nitrogen gas from the jet nozzle. This more comprehensive cleaning of the FA fiber array is combined with rapid drying, improving work efficiency. Attached Figure Description

[0024] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0025] like Figures 1 to 5 As shown, this utility model provides a fixture for cleaning FA fiber arrays, including a fixed frame 1, a flip frame 2, a positioning frame 3, an air jet head 4, a take-up and release groove 6, a groove 7, a support plate 12, and a limiting protrusion 13. The middle of the left and right ends of the flip frame 2 are rotatably connected to the inner side of the fixed frame 1 through a rotating shaft, and four positioning frames 3 are locked and fixed inside the flip frame 2.

[0026] Several jet heads 4 are installed inside the fixed frame 1. The jet heads 4 are located below the positioning frame 3. The air outlet of the jet head 4 is directly facing the bottom of the positioning frame 3. The jet head 4 is connected to an external nitrogen delivery device (not shown in the figure) through a gas supply pipe. The jet head 4 is used to spray nitrogen. The sprayed nitrogen pre-cleans the FA fiber array inside the fixed frame 1 and also dries the cleaned FA fiber array.

[0027] To facilitate cleaning the FA fiber array inside the positioning frame 3, the positioning frame 3 is a hollow structure that runs vertically through the frame, and the upper and lower end faces of the positioning frame 3 are flush with the upper and lower end faces of the flipping frame 2, respectively.

[0028] The positioning frame 3 is equipped with two sets of mutually symmetrical limiting components, which are used to provide limiting for the FA fiber array;

[0029] The limiting component includes a take-up slot 6 and a groove 7 respectively opened on the bottom end face and inner wall of the positioning frame 3, a support plate 12 rotatably installed in the take-up slot 6 for providing support for the FA fiber array, and a clamping component set in the groove 7 for clamping the FA fiber array. A limiting protrusion 13 is provided in the take-up slot 6. When the support plate 12 is in the extended state, it is in contact with the limiting protrusion 13, so that the support plate 12 is in an inclined state when it extends from the take-up slot 6. After the flipping frame 2 is flipped, the support plate 12 is in an inclined state, which makes it convenient for the inclined support plate 12 to rotate downward and be stored in the take-up slot 6 under the action of gravity.

[0030] The free end of the support plate 12 extends to the bottom of the inner side of the positioning frame 3. The support plate 12 has an L-shaped plate structure and its corners have a continuous S-shaped bending transition, which increases the weight at the corners of the support plate 12 and makes it convenient for the flipping frame 2 to automatically rotate downwards and be stored in the storage slot 6 after flipping.

[0031] In this embodiment, the clamping assembly includes a stainless steel clamping plate 8 slidably installed in the groove 7 for clamping the FA fiber array, an electromagnet 10 installed in the groove 7 and facing the clamping plate 8, and the clamping plate 8 is connected to the inside of the groove 7 by a spring 9.

[0032] In this embodiment, spring 9 is a plastic spring;

[0033] When the electromagnet 10 is energized, the magnetic attraction force on the clamping plate 8 is greater than the elastic force of the spring 9. After the electromagnet 10 is energized, it can stably attract the clamping plate 8 to move horizontally along the inner side of the groove 7.

[0034] In this embodiment, a protective pad 11 is provided on the outer end face of the clamping plate 8 and the free end of the support plate 12. The protective pad 11 provides protection for the FA fiber array and reduces the damage to the FA fiber array caused by hard contact between the clamping plate 8 and the FA fiber array.

[0035] In the above, the protective pad 11 is a silicone sheet, but it can also be a rubber sheet or a flexible Teflon sheet;

[0036] In this embodiment, a servo motor 5 is installed on the side surface of the fixed frame 1, and the output shaft of the servo motor 5 is connected to the middle of the left end face of the flipping frame 2 through a coupling.

[0037] Specifically, each electrical device is connected to an external controller via control cables, and the jet head 4 is connected to an external nitrogen delivery device via an air pipe. The electromagnet 10 is energized to generate magnetic force, and the clamping plate 8 moves inward along the groove 7 under the action of magnetic force. The spring 9 is elastically compressed by the pressure of the clamping plate 8. Then, the FA fiber arrays that need to be cleaned are placed into each positioning frame 3 in sequence, and the FA fiber arrays move downward to contact the support plate 12.

[0038] Then, the electromagnet 10 is de-energized, and the clamping plate 8 moves outward along the groove 7 under the elastic force of the spring 9 to clamp and fix the FA fiber array. The external nitrogen delivery device is controlled to input nitrogen into the jet head 4. The nitrogen is sprayed upward to blow off the dust at the bottom of the FA fiber array. The servo motor 5 is controlled to drive the flipping frame 2 to rotate. At this time, one side of the pre-cleaned FA fiber array faces upward, and the inclined support plate 12 rotates inward to be stored in the take-up slot 6. The side that has not been pre-cleaned rotates downward, and the jet head 4 can continue to blow air to pre-clean the bottom surface of the FA fiber array.

[0039] Next, use cotton swabs soaked in an appropriate amount of cleaning agent to carefully wipe the edges of the fiber array, the connection between the outer shell and the fiber, and other parts to slowly remove any oil stains or minor dirt, thus completing the cleaning of the FA fiber array. After one side is cleaned, flip the flipping frame 2 again so that the cleaned side of the FA fiber array is facing down, and the nitrogen gas sprayed from the jet head 4 blows the cleaned side to dry it, thereby improving the cleaning efficiency of the FA fiber array.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
