Description

Technical Field

[0001] This utility model relates to the field of FA fiber array polishing technology, specifically to a FA fiber array polishing angle adjustment structure. Background Technology

[0002] With the rapid development of optical communication technology towards high speed and large capacity, extremely stringent requirements have been placed on the coupling efficiency and quality of optical fiber connections. In scenarios such as long-distance backbone network transmission and high-speed interconnection within data centers, traditional optical fiber connection methods are no longer able to meet the ever-increasing performance demands. Special-angled optical fiber end faces, such as tapered and wedge-shaped ones, have become one of the key factors in improving the overall performance of optical communication systems because they can significantly improve the optical coupling efficiency between optical fibers and reduce optical signal reflection and loss. For example, in 400G, 800G, and even higher speed optical modules, optical fiber arrays polished at specific angles can effectively reduce insertion loss and improve the stability and reliability of signal transmission.

[0003] Most existing fiber polishing devices can only achieve polishing at a single angle or within a limited angle range, making it difficult to meet diverse special angle requirements. For example, some simple polishing devices can only perform planar polishing and cannot achieve processing of complex angles such as conical or wedge shapes. Therefore, a FA fiber array polishing angle adjustment structure is needed to achieve polishing at multiple angles or shapes. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] See attached document Figure 1 - Appendix Figure 5This utility model provides a fiber optic array polishing angle adjustment structure, including a fiber polishing machine 1. A vertical drive assembly 2 is located at the top of the fiber polishing machine 1. An angle drive connecting frame 3 is connected to one side of the vertical drive assembly 2, and an angle adjustment assembly 4 is connected to one side of the angle drive connecting frame 3. The vertical drive assembly 2 includes a fixing frame 21, the bottom of which is fixedly connected to the top of the fiber polishing machine 1. A limiting groove 22 is formed inside the fixing frame 21. A servo motor 23 is located at the top of the fixing frame 21, and a threaded rod 24 is inserted into the limiting groove 22. The angle drive connecting frame 3 includes a connecting frame 31, a threaded seat 32 is fixedly located on one side of the connecting frame 31, and a connecting plate 33 is fixedly located at the bottom of the connecting frame 31. A second servo motor 34 is provided on the side, a second threaded rod 35 is inserted into the connecting frame 31, the angle adjustment component 4 includes a positioning shaft 411, a positioning sleeve 412 is fixedly provided at one end of the positioning shaft 411, a motor mounting plate 413 is fixedly provided on the outside of the positioning sleeve 412, a fiber optic clamping device body 414 is inserted into the positioning sleeve 412, a movable sleeve 415 is sleeved on the outside of the fiber optic clamping device body 414, a movable shaft 416 is fixedly provided on one side of the movable sleeve 415, a second threaded seat 417 is provided at one end of the movable shaft 416, a third servo motor 418 is provided on the top of the motor mounting plate 413, a transmission shaft 419 is provided at the bottom of the third servo motor 418, and a driving component is provided between the transmission shaft 419 and the fiber optic clamping device body 414.

[0027] In this implementation scheme, to achieve precise control and stable adjustment of multi-angle polishing of the fiber array, a servo motor 23 drives a threaded rod 24 to rotate, causing the threaded seat 32 to move longitudinally within the limiting groove 22. This achieves precise control of the height of the angle adjustment component 4, allowing the contact pressure and polishing depth between the fiber end face and the polishing disc to be adjusted as needed, ensuring process consistency during polishing at different angles. A servo motor 34 drives a threaded rod 35 to rotate, pushing the threaded seat 417 to slide laterally within the connecting frame 31. A movable shaft 416 drives a movable sleeve 415 to deflect, causing the fiber clamping device body 414 to tilt around the positioning shaft 411. This allows for continuous adjustment of the fiber polishing angle in the horizontal direction, meeting diverse angle requirements. The positioning shaft 411 and the positioning sleeve 412 are connected by bearings to form a fixed rotation fulcrum, ensuring the rotational accuracy of the fiber clamping device body 414 when tilted and avoiding angle deviation. The movable sleeve 415 and the ball bearings... Structure: The ball bearings on the inner wall of the movable sleeve 415 roll in contact with the fiber optic clamping device body 414, and are connected by the bearings of the movable rotating shaft 416 to eliminate mechanical jamming during tilt adjustment and ensure smooth angle adjustment. Through the transmission structure of pulley 1 420, belt 421, and pulley 2 422, the fiber optic clamping device body 414 is driven to rotate at a constant speed, which, in conjunction with the movement of the grinding disc, achieves grinding of conical, spherical, and other curved surfaces. Through the coordinated control of speed and angle adjustment, the contour accuracy of the curved surface grinding is ensured. Through the three-dimensional linkage of the vertical drive component 2, the angle drive connecting frame 3, and the angle adjustment component 4, a multi-degree-of-freedom adjustment system of "height-horizontal angle-rotation" is constructed, enabling the fiber optic array to form any tilt angle and rotation posture in space. Combined with the closed-loop control of the servo motor and the precision transmission of the mechanical structure, automated grinding of special angles / shapes such as conical, wedge, and spherical shapes is achieved, solving the problems of single angle adjustment and insufficient precision of existing equipment.

[0028] To achieve the goal of controlling the longitudinal movement of the angle adjustment component 4 so that the optical fiber held by the optical fiber clamping device body 414 can contact the polishing disc of the optical fiber polishing machine 1, the device adopts the following technical solution: servo motor 23 is fixedly mounted on the top of the fixed frame 21. The protruding end of servo motor 23 is fixedly connected to one end of threaded rod 24. The top of threaded rod 24 passes through the top of limiting groove 22 and is connected to the top of limiting groove 22 through a bearing. The bottom of threaded rod 24 is connected to the bottom of limiting groove 22 through a bearing. Threaded seat 32 is located inside limiting groove 22 and is slidably connected to limiting groove 22. Threaded seat 32 is sleeved on the outside of threaded rod 24 and is threadedly connected to threaded rod 24. When servo motor 23 is started, its output shaft drives threaded rod 24 to rotate synchronously. Since threaded seat 32 is connected to threaded rod 24 through a threaded pair, and threaded seat 32... Constrained by the limiting groove 22, the threaded rod 24 can only slide along the axial direction. Therefore, the rotational motion of the threaded rod 24 is converted into the linear motion of the threaded seat 32. The threaded seat 32 is fixedly connected to the connecting frame 31, thereby driving the entire angle drive connecting frame 3 to move longitudinally along the limiting groove 22. The angle adjustment component 4 is connected to the connecting frame 31 through the positioning shaft 411 and the movable shaft 416. Therefore, it rises and falls synchronously with the connecting frame 31, ultimately realizing the contact and separation action between the optical fiber and the polishing disc in the optical fiber clamping device body 414. By controlling the forward and reverse rotation and the rotation angle of the servo motor 23, the downward pressure of the optical fiber can be precisely adjusted, thereby controlling the polishing depth and contact pressure. This structure utilizes the self-locking characteristic of the threaded transmission to ensure the stability of the position of the angle adjustment component 4 during the polishing process. With the closed-loop control of the high-precision servo motor, the height adjustment accuracy at the micron level can be achieved to meet the polishing process requirements of optical fibers of different specifications.

[0029] To achieve precise control over multi-angle and curved surface polishing of optical fibers, this device employs the following technical solution: One end of the positioning shaft 411 passes through the connecting plate 33 and is connected to the connecting plate 33 via a bearing; the positioning sleeve 412 is fitted onto the outside of the optical fiber clamping device body 414 and is connected to the optical fiber clamping device body 414 via a bearing; the movable sleeve 415 is fitted onto the outside of the optical fiber clamping device body 414, and multiple balls are embedded inside the movable sleeve 415, all of which are in rolling connection with the optical fiber clamping device body 414; one end of the movable shaft 416 extends into the threaded seat 417 and is connected to the threaded seat 417 via a bearing; the threaded seat 417 is located inside the connecting frame 31 and is slidably connected to the connecting frame 31; the threaded seat 416... 17 is sleeved outside the threaded rod 35 and connected to the threaded rod 35 by threads. Servo motor 3 418 is fixedly mounted on the top of motor mounting plate 413. The output end of servo motor 3 418 is fixedly connected to the top of transmission shaft 419. Transmission shaft 419 passes through motor mounting plate 413 and is connected to motor mounting plate 413 by bearings. The driving component includes pulley 1 420 and pulley 2 422. Pulley 1 420 is fixedly sleeved outside the transmission shaft 419. Pulley 2 422 is fixedly sleeved outside the fiber optic clamping device body 414. A belt 421 is sleeved outside pulley 1 420 and pulley 2 422. Pulley 1 420 and pulley 2 422 are driven and connected by belt 421. The process of multi-angle tilt adjustment is realized. When servo motor 2 34 drives threaded rod 2 35 to rotate, threaded seat 2 417 slides laterally along connecting frame 31. Since the movable shaft 416 is connected to threaded seat 2 417 via bearings, movable sleeve 415 moves synchronously with threaded seat 2 417 and maintains rolling contact with fiber optic clamping device body 414 via ball bearings. At this time, positioning sleeve 412 forms a fixed rotation fulcrum with connecting plate 33 via positioning shaft 411, forcing fiber optic clamping device body 414 to tilt around the axis of positioning shaft 411. By controlling the rotation angle of servo motor 2 34, the tilt angle can be precisely adjusted continuously within the range of 3°-60° to meet different angle requirements such as conical and wedge shapes. During the self-rotation drive process of curved surface grinding, when servo motor 3 418 is started... Its output shaft drives the transmission shaft 419 to rotate. The pulley 420 fixed on the transmission shaft 419 drives the pulley 422 via the belt 421, which in turn drives the fiber optic clamping device body 414 to rotate at a constant speed around its own axis. Since the fiber optic clamping device body 414, the positioning sleeve 412, and the movable sleeve 415 are all connected by bearings or balls, the rotation is not affected by the tilt angle, ensuring stable rotation under any tilt posture. By coordinating the tilt angle of the servo motor 34 and the speed of the servo motor 418, combined with the planar motion of the grinding disc, complex curved surface contours such as cones and spheres can be precisely machined. Through the dual-degree-of-freedom design of "fixed-point tilt + independent rotation", combined with high-precision servo control and precision transmission mechanism,Breaking through the limitations of traditional fiber optic polishing equipment, which can only perform polishing at a single angle or on a flat surface, this system can automatically process complex end faces such as tapered, wedge-shaped, and spherical shapes, meeting the precision machining needs of high-speed optical communication, fiber optic sensing, and other fields requiring fibers with special angles.

[0030] The usage process of this utility model is as follows: When using this utility model, connect an external power source. The optical fiber to be ground is fixed in the optical fiber clamping device body 414 using existing technology. When adjusting the grinding angle, start the servo motor 34. The rotation of the servo motor 34 causes the threaded rod 35 to rotate, which in turn causes the threaded seat 417 to slide laterally in the connecting frame 31. The movement of the threaded seat 417 causes the movable sleeve 415 to tilt the optical fiber clamping device body 414 via the movable rotating shaft 416. The optical fiber clamping device body 414 is connected to the positioning sleeve 412. The positioning sleeve 412 is fixedly connected to the connecting plate 33 via the positioning rotating shaft 411. The positioning rotating shaft 411 and the connecting plate 33 are connected by bearings. This allows the positioning shaft 411 to rotate at a fixed point. When the fiber optic clamping device body 414 is tilted, the movable sleeve 415 slides along the fiber optic clamping device body 414 via ball bearings. Simultaneously, the movable sleeve 415 is connected to the bearing of the threaded seat 417 via the movable shaft 416, allowing the movable sleeve 415 to tilt synchronously. This prevents jamming when adjusting the angle of the fiber optic clamping device body 414. To ensure contact between the fiber and the polishing disc of the fiber polishing machine 1, when the angle adjustment component 4 is raised or lowered, the servo motor 23 is activated, causing the threaded rod 24 to rotate. This, in turn, causes the threaded seat 32 to drive the connecting frame 31 to move longitudinally. The movement of the connecting frame 31, through the threaded seat 417 and the positioning shaft 417, allows the fiber optic clamping device body 415 to move longitudinally. The rotating shaft 411 causes the angle adjustment component 4 to move longitudinally, bringing the optical fiber into contact with the polishing disc of the optical fiber polishing machine 1. The optical fiber is polished according to the adjusted angle. By adjusting different angles beforehand, different angles can be polished onto the optical fiber, resulting in a surface-shaped optical fiber. When a tapered angle needs to be polished, during the optical fiber polishing process, the servo motor 418 is activated. The servo motor 418 drives the transmission shaft 419 to rotate. The rotation of the transmission shaft 419, through the pulley 420, causes the belt 421 to drive the pulley 422 to rotate. The rotation of the pulley 422 drives the optical fiber clamping device body 414 to rotate. The optical fiber clamping device body 414 rotates through the movable sleeve... The ball bearing connection in 415 and the bearing connection with the positioning sleeve 412 enable the fiber clamping device body 414 to drive the fiber to be polished to rotate. In conjunction with the rotating polishing disc, the fiber end is polished into a conical shape. When a wedge angle needs to be polished, the movable sleeve 415 is adjusted to tilt the fiber clamping device body 414 to a specific angle according to the angle and shape requirements of the wedge. At the same time, the servo motor 23 is controlled to lower the fiber to a suitable position on the polishing disc. During the polishing process, the rotation speed and number of rotations of the fiber driven by the servo motor 34 can be flexibly controlled according to the sharpness and size of the wedge. In conjunction with the movement of the polishing disc, the wedge shape is gradually polished.

Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
