Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber transmission, and more specifically, to a high-power optical fiber rotary connector and a bonding process thereof. Background Art

[0002] Fiber optic rotary connectors use optical fiber as a transmission medium to achieve efficient and reliable data transmission between a rotating platform and a stationary platform. Fiber optic rotary connectors not only have the advantages of small size, light weight, low cost, strong resistance to electromagnetic interference, and good confidentiality, but also have multi-channel transmission capabilities and are suitable for a variety of complex environments and high-demand application scenarios, such as energy, national defense, aerospace, aviation, navigation, industry and other fields. Therefore, fiber optic rotary connectors play an important role in promoting the development of informatization and intelligence, and improving equipment performance and reliability. They are an indispensable key component in the development of modern science and technology and industry.

[0003] Existing fiber optic rotary connectors often use screws to adjust and fix the position of the fiber optic collimator, that is, the fiber optic collimator is accurately positioned by manually adjusting the screws to ensure that it is correctly aligned with another collimator, thereby achieving efficient coupling between the two fiber optic collimators. This type of fiber optic rotary connector is relatively cumbersome to operate in the actual production process, and it is difficult to achieve high-power light transmission. At the same time, the screws may loosen and vibrate during use, resulting in reduced product quality. Summary of the invention

[0004] The present invention provides a high-power optical fiber rotary connector and its bonding process, and aims to solve the problem that the existing optical fiber rotary connector often uses screws to adjust and fix the position of the optical fiber collimator, so as to achieve efficient coupling between the two optical fiber collimators. The operation of this optical fiber rotary connector is relatively cumbersome in the actual production process, and it is difficult to achieve high-power optical transmission. At the same time, the screws may loosen and vibrate during use, resulting in reduced product quality.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a high-power optical fiber rotary connector, comprising a rotor, a housing 1 is glued inside the rotor, an optical fiber beam expander collimator 1 is arranged inside the housing 1 (12), and a glue injection hole 1 is opened on the housing 1, a housing 2 is rotatably arranged outside the rotor, an optical fiber beam expander collimator 2 is arranged inside the housing 2, and a glue injection hole 2 is opened on the housing 2, a stator is fixedly arranged outside the housing 2, and the input end of the rotor and the output end of the stator are both used for installing optical fiber cables.

[0006] In a preferred embodiment, a bearing is fixedly arranged on the inner wall of the stator, and the inner ring of the bearing is fixedly arranged on the outer side of the rotor.

[0007] A bonding process for a high-power optical fiber rotary connector comprises the following steps:

[0008] Step 1: Place the optical fiber beam expander collimator 1 in the middle of the rotor, adjust the direction of the optical fiber beam expander collimator 1, and pre-fix the optical fiber beam expander collimator 1 through the positioning mechanism;

[0009] Step 2: A light source is introduced into the input end of the optical fiber beam expander collimator 1, and the light source is output through the output end of the optical fiber beam expander collimator 1. A charge coupled device is placed at the output end of the optical fiber beam expander collimator 1 to display the light spot position;

[0010] Step 3: If the placement direction of the optical fiber beam expander collimator 1 does not completely coincide with the axial direction of the bearing, the rotor is rotated by the positioning mechanism, and the light spot output from the output end of the optical fiber beam expander collimator 1 rotates with the rotor, and the motion trajectory of the light spot moves in a circular motion along the rotation axis of the rotor;

[0011] Step 4: Adjust the direction of the optical fiber beam expander collimator 1 so that the position of the light spot output from the output end of the optical fiber beam expander collimator 1 is close to the rotation axis of the rotor;

[0012] Step 5: Move the position of the charge coupled device away from the optical fiber beam expander collimator 1, and then rotate the rotor to repeat the operations of steps 3 and 4, and repeatedly adjust the direction of the optical fiber beam expander collimator 1 so that its rotation axis coincides with the rotation axis of the bearing;

[0013] Step 6: Use the glue coating mechanism to inject glue into the glue injection hole 1 to fix the position of the optical fiber beam expander collimator 1;

[0014] Step 7: Place the second optical fiber beam expander collimator into the stator, repeat the operations of steps 2, 3, 4 and 5, and monitor the change of coupling efficiency in real time to optimize the coupling efficiency between the second optical fiber beam expander collimator and the first optical fiber beam expander collimator;

[0015] Step 8: Inject glue into the second glue injection hole through the glue coating mechanism to fix the position of the second optical fiber beam expander collimator.

[0016] In summary, during the preparation work, ensure that all necessary tools and materials are ready, clean the relevant parts, and ensure that there is no dust or impurities that affect subsequent operations. Gently insert the fiber beam expander collimator 1 into the center of the rotor. Use the positioning mechanism to preliminarily fix the fiber beam expander collimator 1 to ensure that it is basically aligned with the axis of the rotor. Connect the light source to the input end of the fiber beam expander collimator 1 to ensure that the light source is stable and reliable. Place a charge-coupled device CCD at the output end of the fiber beam expander collimator 1, turn on the light source, and observe the position and shape of the light spot. Correct the direction of the fiber beam expander collimator 1, analyze the position of the light spot, and determine whether the direction of the fiber beam expander collimator 1 completely coincides with the axis of the rotor. Use the positioning mechanism to fine-tune the angle of the fiber beam expander collimator 1 so that the position of the light spot is more centered; repeat the test and adjustment process many times until the position of the light spot is optimal; further adjust the directionality of the fiber beam expander collimator 1, and make more detailed adjustments to ensure that the position of the light spot is as close to the rotation axis of the rotor as possible. Use the charge-coupled device again to verify the effect after adjustment to ensure that the position of the light spot meets the requirements. Finally, fix the fiber beam expander collimator 1. After completing all adjustments, thoroughly check the position and light spot of the fiber beam expander collimator 1 again. Use the glue coating mechanism to inject an appropriate amount of glue into the glue injection hole 1, wait for the glue to solidify, and ensure that the fiber beam expander collimator 1 is stable and immovable. Repeat steps 1 to 5 for installing the fiber beam expander collimator 2. Repeat all the previous steps for the fiber beam expander collimator 2 to ensure that it is also accurately aligned. During the whole process, continue to monitor the coupling efficiency between the two fiber beam expanders and make minor adjustments when necessary to achieve the best coupling effect.

[0017] Confirm that the position and coupling efficiency of the optical fiber beam expander collimator 2 meet the design requirements, and use the glue coating mechanism to inject glue into the glue injection hole 2 to complete the permanent fixation of the optical fiber beam expander collimator 2.

Use the charge coupled device again to verify the effect after adjustment to ensure that the position of the light spot meets the requirements. Finally, fix the optical fiber beam expander collimator 1. After completing all adjustments, fully check the position and light spot of the optical fiber beam expander collimator 1 again.
