Description

Technical Field

[0001] This invention relates to the field of optical fiber winding technology, and in particular to an optical fiber winding device and a fiber splitter. Background Technology

[0002] In the production of fiber laser systems and corresponding optical devices, it is often necessary to cut passive and active optical fibers. During mass production of these cut fibers, manual length-based fiber cutting is inefficient and cannot meet production demands. Therefore, automated fiber slitting machines are currently commonly used for fiber winding.

[0003] In automatic fiber splitters, fiber take-up reels are required for fiber winding. Existing fiber take-up reels are heavy and have high manufacturing costs. Furthermore, after the fiber is wound up, the fiber roll is tightly attached to the side of the take-up reel, making it inconvenient to remove the fiber roll.

[0004] Therefore, there is an urgent need for an optical fiber winding device and a fiber splitter to solve the above problems. Summary of the Invention

[0005] According to one aspect of the present invention, the object is to provide an optical fiber winding device on which an optical fiber can be wound, the optical fiber winding device facilitating the quick removal of the wound optical fiber, thereby improving the convenience and efficiency of the optical fiber winding process.

[0008] A connecting shaft, which is capable of rotating about its own axis and moving along its own axis;

[0009] The winding mechanism is driven to one end of the connecting shaft and includes a plurality of fiber winding posts arranged in a circular array. The plurality of fiber winding posts can rotate around the axis of the connecting shaft and rotate simultaneously with the rotation of the connecting shaft, so that the optical fiber is wound around the outside of the plurality of fiber winding posts. The distance between the plurality of fiber winding posts can decrease or increase as the connecting shaft moves along its own axis.

[0010] As a preferred embodiment of the optical fiber winding device provided by the present invention, the optical fiber winding device further includes a rotation drive mechanism and a rotation transmission mechanism. The rotation transmission mechanism includes a transmission belt. The rotation drive mechanism is spaced apart from the connecting shaft. The transmission belt is wrapped around the output end of the rotation drive mechanism and the connecting shaft. The rotation drive mechanism can drive the connecting shaft to rotate through the transmission belt.

[0011] As a preferred embodiment of the optical fiber winding device provided by the present invention, the rotation transmission mechanism further includes a transmission wheel, which is disposed between the rotation drive mechanism and the connecting shaft, and the transmission belt passes around the transmission wheel and is wound around the connecting shaft.

[0012] As a preferred embodiment of the optical fiber winding device provided by the present invention, the rotating transmission mechanism further includes a stop wheel, which is coaxially and fixedly disposed on the periphery of the connecting shaft, and the transmission belt passes around the transmission wheel and is wound around the stop wheel.

[0013] As a preferred embodiment of the optical fiber winding device provided by the present invention, the optical fiber winding device further includes a linear motion drive mechanism, which is disposed at one end of the connecting shaft in the axial direction and is configured to drive the connecting shaft to move along its own axial direction.

[0014] As a preferred embodiment of the optical fiber winding device provided by the present invention, the optical fiber winding device further includes a linear motion transmission mechanism. The linear motion transmission mechanism includes a threaded rotating part and a threaded connecting seat. The connecting shaft is movably disposed on the threaded connecting seat. The threaded rotating part is coaxially connected to the output end of the linear motion drive mechanism and the end of the connecting shaft, and is screwed to the threaded connecting seat. The threaded rotating part can rotate under the drive of the linear motion drive mechanism to drive the connecting shaft to move relative to the threaded connecting seat along its own axial direction.

[0015] As a preferred embodiment of the optical fiber winding device provided by the present invention, the linear motion transmission mechanism further includes a bearing seat, which is disposed in the threaded connection seat, and the connecting shaft is rotatably disposed in the bearing seat.

[0016] As a preferred embodiment of the optical fiber winding device provided by the present invention, the winding mechanism includes multiple connecting frames, which are arranged radially. Multiple fiber winding posts are evenly connected to the multiple connecting frames, and the multiple connecting frames are drivenly connected to the connecting shaft. The distance between the multiple connecting frames can be reduced or increased as the connecting shaft moves along its own axial direction.

[0017] As a preferred embodiment of the optical fiber winding device provided by the present invention, the optical fiber winding device further includes a plurality of linkage mechanisms, each linkage mechanism corresponding to the connecting frame. Each linkage mechanism includes a first rod portion and a second rod portion. The first rod portion is rotatably connected to the connecting shaft, and the second rod portion is rotatably connected to the first rod portion and connected to the connecting frame. The connecting shaft can move along its own axis direction, thereby driving the first rod portion and the second rod portion to rotate relative to each other.

[0018] According to another aspect of the present invention, an object is to provide a fiber splitter comprising a base and an optical fiber winding device as described in any of the above embodiments, the optical fiber winding device being disposed on the base.

[0019] The beneficial effects of this invention are:

[0020] The optical fiber winding device provided by the present invention includes a connecting shaft and a winding mechanism.

[0021] The connecting shaft is capable of rotating around its own axis and moving along its own axial direction. The winding mechanism, driven by one end of the connecting shaft, includes multiple fiber-winding posts arranged in a circular array. These posts rotate around the axis of the connecting shaft, rotating simultaneously with the shaft's rotation, so that the optical fiber is wound around the outside of the posts. The distance between the posts decreases or increases as the connecting shaft moves along its own axial direction. In other words, during the fiber winding process, the connecting shaft drives the multiple posts to rotate as a whole, winding the fiber around the periphery of the posts. After winding, the movement of the connecting shaft along its axial direction reduces the distance between the posts, facilitating quick removal of the wound fiber and improving the convenience and efficiency of the fiber winding process.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0038] Figure 1 This diagram illustrates the structure of the optical fiber winding device provided in an embodiment of the present invention. Figure 1 ; Figure 2 This diagram illustrates the structure of the optical fiber winding device provided in an embodiment of the present invention. Figure 2 ; Figure 3 A schematic diagram of the internal structure of the optical fiber winding device provided in an embodiment of the present invention is shown. (Refer to...) Figures 1-3 This embodiment provides an optical fiber winding device and a fiber splitter. The fiber splitter includes a base 10 and the optical fiber winding device provided in this embodiment. The optical fiber winding device is disposed on the base 10 and is used to wind up the optical fiber.

[0039] Specifically, the optical fiber winding device includes a connecting shaft 100, a winding mechanism 200, a rotary drive mechanism 300, a rotary transmission mechanism 400, a linear motion drive mechanism 500, and a linear motion transmission mechanism 600. The linear motion drive mechanism 500 is connected to the connecting shaft 100 via the linear motion transmission mechanism 600, the rotary drive mechanism 300 is connected to the connecting shaft 100 via the rotary transmission mechanism 400, and the winding mechanism 200 is drively connected to the connecting shaft 100. The connecting shaft 100 can rotate around its own axis under the drive of the rotary drive mechanism 300, and can also move along its own axis under the drive of the linear motion drive mechanism 500. The winding mechanism 200 can rotate with the rotation of the connecting shaft 100 so that the optical fiber is wound on its outer periphery. The outer diameter of the winding mechanism 200 can also shrink or expand as the connecting shaft 100 moves along the axial direction. When the outer diameter of the winding mechanism 200 shrinks, it is convenient to quickly remove the wound optical fiber, thereby improving the convenience and efficiency of the optical fiber winding process.

[0040] More specifically, the rotation drive mechanism 300 is mounted on the base 10. The rotation drive mechanism 300 can be a rotary motor, and its rotational output end is connected to the rotation transmission mechanism 400. The rotation transmission mechanism 400 includes a transmission belt 410 and a drive pulley 440. The rotation drive mechanism 300 and the connecting shaft 100 are spaced apart in a direction perpendicular to the axis of the connecting shaft 100. The drive pulley 440 is coaxially fixed to the output end of the rotation drive mechanism 300, and the transmission belt 410 is wrapped around the drive pulley 440 and circumferentially around the connecting shaft 100. The rotation drive mechanism 300 can drive the connecting shaft 100 to rotate around its axis under the action of friction through the drive pulley 440 and the transmission belt 410. The transmission belt 410 can be a drive belt or similar material.

[0041] More specifically, in this embodiment, the rotary transmission mechanism 400 further includes an abutment wheel 430. The abutment wheel 430 is coaxially and fixedly disposed on the periphery of the connecting shaft 100, and the transmission belt 410 is circumferentially wrapped around the abutment wheel 430. This arrangement increases the contact area between the transmission belt 410 and the connecting shaft 100, thereby increasing the friction between them and ensuring the rotational driving effect of the transmission belt 410 on the connecting shaft 100.

[0042] More specifically, the rotary transmission mechanism 400 also includes a transmission wheel 420. The transmission wheel 420 is disposed between the rotary drive mechanism 300 and the connecting shaft 100 in a direction perpendicular to the axial direction of the connecting shaft 100. The transmission belt 410 passes over the drive wheel 440 and the transmission wheel 420, and then passes over the abutment wheel 430. The transmission wheel 420 abuts against the transmission belt 410, ensuring its tautness and improving the smoothness of its rotation and the reliability of its transmission.

[0043] Continue to refer to Figures 1-3 The linear motion drive mechanism 500 is disposed at one end of the connecting shaft 100 along its axial direction. Specifically, the linear motion drive mechanism 500 can be a rotary motor, whose rotational output end converts the rotational motion into a movement motion along the axial direction of the connecting shaft 100 through the linear motion transmission mechanism 600.

[0044] Specifically, the linear motion transmission mechanism 600 includes a threaded rotating part 610 and a threaded connecting seat 620. The connecting shaft 100 is movably disposed in the threaded connecting seat 620. The threaded rotating part 610 is coaxially connected to the output end of the linear motion drive mechanism 500 and the end of the connecting shaft 100, and is screwed into the threaded connecting seat 620. The threaded rotating part 610 can rotate under the rotation of the linear motion drive mechanism 500. Under the constraint of the threaded connecting seat 620, the threaded rotating part 610 spirals forward to push the connecting shaft 100 to move relative to the threaded connecting seat 620 along the axial direction, away from the drive end of the linear motion drive mechanism 500.

[0045] More specifically, the linear motion transmission mechanism 600 also includes a bearing housing 630, which is disposed within the threaded connection seat 620, and the connecting shaft 100 is rotatably disposed within the bearing housing 630. The bearing housing 630 can support the connecting shaft 100 and ensure the smooth rotation of the connecting shaft 100.

[0046] Continue to refer to Figure 1 and Figure 3 The winding mechanism 200 includes a plurality of fiber winding posts 210 arranged in a circular array. The plurality of fiber winding posts 210 are able to rotate around the axis of the connecting shaft 100 and rotate simultaneously with the rotation of the connecting shaft 100, so that the optical fiber is wound around the outside of the whole formed by the plurality of fiber winding posts 210.

[0047] Specifically, the winding mechanism 200 also includes a positioning post 230. The positioning post 230 is disposed at the end of a fiber winding post 210. One end of the optical fiber can be clamped between the positioning post 230 and the corresponding fiber winding post 210, facilitating subsequent continuous winding of the optical fiber.

[0048] Continue to refer to Figure 3 The fiber optic winding device also includes multiple linkage mechanisms 700, through which the winding mechanism 200 is connected to the connecting shaft 100. Under the action of the linkage mechanisms 700, the outer diameter of the winding mechanism 200 can change as the connecting shaft 100 moves along its axial direction. That is, the distance between the multiple fiber winding posts 210 can decrease or increase as the connecting shaft 100 moves along its own axial direction. When the connecting shaft 100 moves away from the driving end of the linear motion drive mechanism 500 along its axial direction, it can push against the linkage mechanism 700, which then actuates to reduce the distance between the multiple fiber winding posts 210.

[0049] Specifically, the winding mechanism 200 further includes multiple connecting frames 220 arranged radially, with multiple fiber winding posts 210 evenly distributed and connected to the multiple connecting frames 220. In this embodiment, each connecting frame 220 has two fiber winding posts 210. The connecting frame 220 is driven to the connecting shaft 100 via a linkage mechanism 700, and the distance between the multiple connecting frames 220 can decrease or increase as the connecting shaft 100 moves along its own axial direction.

[0050] More specifically, each linkage mechanism 700 corresponds to a connecting frame 220. Each linkage mechanism 700 includes a first rod portion 710 and a second rod portion 720. The first rod portion 710 is rotatably connected to the connecting shaft 100, and the second rod portion 720 is rotatably connected to the first rod portion 710 and connected to the connecting frame 220. A support plate 11 is provided on the base 10 corresponding to the mounting position of the linkage mechanism 700. The connecting shaft 100 and the winding mechanism 200 are located on opposite sides of the support plate 11. The second rod portion 720 is rotatably connected to the support plate 11 and extends to the other side of the support plate 11, ultimately connecting to the end of the connecting frame 220. The connecting shaft 100 moves along its own axis, which can drive the first rod 710 and the second rod 720 to rotate relative to each other, so that the ends of the multiple second rods 720 that are away from their respective first rods 710 move closer to each other, thereby bringing the multiple connecting frames 220 and the fiber winding post 210 closer to each other, so as to reduce the overall outer diameter of the winding mechanism 200 and make it easier to remove the wound optical fiber.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
