[0002] Optical fiber reel is used to coil optical fiber, to facilitate the disc of optical fiber export. Currently, before winding reel is coiled, the front end of optical fiber is drawn out from threading hole to reserve a section, to facilitate coiling and later detection, but in the current optical fiber automatic production process, since the part of optical fiber reserved is generally simply coiled in the middle of the two ends of winding reel, and winding reel is automatically loaded and unloaded by mechanical hand clamping its two ends, therefore, the part of reserved optical fiber not coiled in groove not only can easily affect the normal work of mechanical hand automatically clamping and loading and unloading winding reel, but also can be easily damaged by mechanical hand when loading and unloading and transporting optical fiber reel, thereby causing detection failure, product quality decline and other problems in later stage SUMMARY

[0005] By adopting the technical scheme, the reserved optical fiber can be clamped and fixed in the gap between the clamping plate, the winding drum and the outer contour surface of the protection end cover, which can not only avoid the interference with the automatic loading and unloading of the winding drum by the mechanical hand, but also protect the reserved optical fiber by the clamping plate at both ends of the winding drum, so that the reserved optical fiber can safely pass through the loading, unloading and transportation processes of the mechanical hand. Before the worker winds the reserved optical fiber to the protection end cover, the telescopic assembly controls the clamping plate to retract into the inside of the protection end cover, so as to facilitate the worker to quickly wind the reserved optical fiber; after the worker winds the reserved optical fiber to the protection end cover, the telescopic assembly controls the clamping plate to extend out of the inside of the protection end cover, and then clamps and fixes the reserved optical fiber in the gap between the clamping plate, the winding drum and the outer contour surface of the protection end cover, so as to ensure that the winding of the reserved optical fiber on the protection end cover cannot be easily unwound.

[0015] By adopting the above technical scheme, after the installation of the protective end cover, the protective end cover can be locked and fixed at one end of the installation cylinder, thereby preventing the protective end cover from being accidentally touched and causing loose connection during the process of clamping the installation cylinder at both ends by the mechanical hand to assemble and disassemble the optical fiber winding disc.

A threading hole 31 is provided on the limiting flange 3 near the outer contour surface of the winding drum 1. The mounting drum 2 is located at the inner center of the winding drum 1 and the two are coaxial. The inner contour surface of the winding drum 1 and the outer contour surface of the mounting drum 2 are fixedly connected by a plurality of ribs 21. The ribs 21 evenly surround the mounting drum 2 and are distributed at both ends of the mounting drum 2. Protective end caps 4 for winding reserved optical fibers are detachably connected at both ends of the mounting drum 2. A plurality of clamps 5 for clamping and fixing the reserved optical fibers are retractably provided on the contour surface of the protective end cap 4. A telescopic component 6 for controlling the telescopic fixing clamp 5 is provided inside the protective end cap 4.

[0037] By means of the removable protective end cap 4 and the retractable clamping plate 5, the reserved optical fiber can be clamped and fixed in the gap between the clamping plate 5, the winding drum 1 and the outer contour surface of the protective end cap 4. This not only prevents the reserved optical fiber from interfering with the work of the robot to automatically load and unload the winding reel, but also protects the reserved optical fiber at both ends of the winding drum 1 by the clamping plate 5, so that it can safely pass through the loading, unloading and transportation processes of the robot. Before the staff winds the reserved optical fiber onto the protective end cap 4, the retractable assembly 6 will control the clamping plate 5 to retract into the interior of the protective end cap 4, so that the staff can quickly wind the reserved optical fiber. After the staff winds the reserved optical fiber onto the protective end cap 4, the retractable assembly 6 will control the clamping plate 5 to extend into the interior of the protective end cap 4, thereby clamping the reserved optical fiber into the gap between the clamping plate 5, the winding drum 1 and the outer contour surface of the protective end cap 4, so as to ensure that the winding of the reserved optical fiber on the protective end cap 4 will not be easily untied.

[0038] like Figure 2 、 Figure 4As shown, the protective end cover 4 comprises a ring edge 41 and a bottom plate 42, the ring edge 41 is provided with a plurality of insertion slots 411 for inserting and fitting the rib plate 21, the bottom plate 42 is provided with a through hole one 421 communicating with the inside of the winding drum 1, the clamping plate 5 is located between the bottom plate 42 and the rib plate 21, and the ring edge 41 is provided with an opening 412 for the clamping plate 5 to slide, which can facilitate the staff to quickly disassemble and install the protective end cover 4 at both ends of the drum 2; the limiting flange 3 is fixedly provided with a honeycomb-shaped reinforcing rib 32 around the protective end cover 4, which can improve the structural strength of the limiting flange 3 to ensure the safe and stable coiling of the optical fiber on the optical fiber winding disc; the top end of the clamping plate 5 is arc-shaped, and the radius of the arc is greater than the inner circle radius of the winding drum 1, which can maximize the clamping range of the clamping plate 5 to ensure that the clamping plate 5 stably clamps the reserved optical fiber.

[0039] As shown in Figure 3 , three pairs of rib plates 21 are arranged at both ends of the mounting drum 2, and each pair of rib plates 21 is fixedly connected with a fan-shaped positioning end cover 7, the radius of the positioning end cover 7 is greater than the radius of the through hole one 421, and the bottom plate 42 is provided with a positioning hole 422 at the edge of the through hole one 421 for fitting the excess part of the positioning end cover 7, which can further improve the stability of the protective end cover 4 after installation.

The two protrusions 63 and the springs 64 are respectively located on both sides of the rib plate 21, and the other ends of the two springs 64 away from the protrusions 63 are connected to the wedge block one 61. When the insertion slot 411 of the ring edge 41 of the protective end cover 4 is aligned with the rib plate 21 and inserted, the wedge block one 61 at the bottom of the clamping plate 5 will gradually approach the wedge block two 62 on the rib plate 21. When the chamfers of the lower end of the wedge block one 61 and the upper end of the wedge block two 62 contact each other, the protective end cover 4 will be initially installed on one end of the installation cylinder 2, and the worker can wind the reserved optical fiber on the outer side wall of the ring body of the protective end cover 4 at this time. After that, continue to push the protective end cover 4 closer to the installation cylinder 2, so that the rib plate 21 is further inserted into the insertion slot 411 of the ring edge 41, and the wedge block two 62 fixed on the rib plate 21 pushes the wedge block one 61 closer to the ring edge 41, so that the clamping plate 5 connected with the wedge block one 61 slides out of the opening 412 of the ring edge 41, and the reserved optical fiber is pushed closer to one end of the winding cylinder 1. Finally, after the rib plate 21 is completely inserted into the insertion slot 411 of the ring edge 41, the clamping plate 5 will be completely stretched out of the side wall of the ring edge 41, so as to clamp and insert the reserved optical fiber wound on the outer side wall of the ring edge 41 into the gap between the clamping plate 5 and the winding cylinder 1. The spring 64 can ensure that the protective end cover 4 is initially installed by pulling the clamping plate 5 back into the protective end cover 4 through the wedge block one 61, so as to facilitate the worker to quickly wind the reserved optical fiber.

The front end of the locking screw 9 is fixedly provided with a polygonal pin 91 penetrating the bottom plate 42 and slidingly inserted into the polygonal pin hole 82. After the protective end cover 4 is installed, the protective end cover 4 can be locked and fixed to one end of the mounting cylinder 2, thereby preventing the mechanical hand from accidentally touching the protective end cover 4 when clamping the two ends of the mounting cylinder 2 to install or remove the fiber winding disc, and causing the connection to be loose. Among them, the bottom plate 42 is provided with a through hole two 423 for rotatably installing the locking shaft 8. The inner wall of the through hole two 423 is provided with a limiting groove 424 around the locking shaft 8.
