Problems solved by technology
[0004] The lower edge of the original winding reel is lifted at a right angle. When the optical fiber is coiled from the plane to the reel, if you are not careful, the fiber will be damaged on the lower edge of the winding reel; the original winding reel needs to be fixed with tape after the fiber is coiled. Doing so will affect the performance of the active fiber, and it is not convenient for the maintenance of the optical path

Embodiment Construction
[0017] In order to facilitate a further understanding of the winding disk of the present invention, the following description will be made in conjunction with the accompanying drawings and embodiments.
[0018] The winding device 1 for edged optical fiber of the present invention is roughly in the shape of a cylinder, with an upper edge 11 and a lower edge 12 protruding from the top and bottom of the winding device 1 respectively, wherein a thread groove is provided on the side of the winding device 1 13, and the lower edge 12 of the winding device 1 forms a slope 121.
[0019] Through such a design, in the process of winding the optical fiber 2 in the winding device 1 of the present invention, it is easier to realize the neat coiling of the optical fiber 2 due to the existence of the threaded groove 13, and the threaded groove 13 increases the contact area between the optical fiber and the winding reel , the heat dissipation effect is better; moreover, the winding device 1 of...

The invention discloses a winding device for an active optical fiber. A threaded groove is formed in the side face of the winding device. A slope is formed on the lower edge of the winding device. The winding device comprises a plurality of fixing clamps. Each fixing clamp comprises a fixing sheet and a clamping sheet perpendicular to the fixing sheet. A long groove is formed in each fixing sheet. Each threaded hole matched with one long groove is formed in a winding disc. A layer of heat-conductive double-faced adhesive tape is adhered to the inner side of the clamping sheet of each fixing clamp. According to the technical scheme, the optical fiber is wound tidily when being wound; the contact area between the optical fiber and a disc body is enlarged and the heat dissipation effect is good; effective protection effect can be achieved when the optical fiber is wound on the winding disc so that the optical fiber is not prone to damage; the wound optical fiber is fixed through the fixing clamps, so that assembly is convenient, the heat-conductive performance is good, and repair is convenient.
Description
technical field [0001] The invention relates to the field of winding devices for active optical fibers, in particular to a winding disk for active optical fibers in high-power optical fiber lasers or optical fiber amplifiers. Background technique [0002] When making high-power fiber lasers or fiber amplifiers, the active fiber part will generate a lot of heat, which needs to be removed from the fiber in time, otherwise it will affect the performance of the optical path or even burn the fiber. The general processing method is: the active optical fiber is coiled on an aluminum disc, and the heat is transferred to the aluminum disc through the close fit between the optical fiber and the side of the aluminum metal. [0003] However, this method is not easy to dissipate heat. Since the winding surface of the original winding reel is smooth and flat, the optical fibers are easy to overlap during the winding process, which will cause the active optical fiber to not easily dissipat...
