Abstract

The invention discloses a curing device for coating optical fibers with UV resin. The curing device comprises a light source, a condensing lens, a condensing trough and a tank body, wherein the lightsource, the condensing lens and the condensing trough are attached in sequence, the condensing lens is located at the front end of the light source and installed at an opening of the condensing trough, the condensing trough is of a bilateral symmetry structure, a high-reflection layer is arranged on the inner wall of the condensing trough, and light rays emitted out from the condensing lens are reflected by the high-reflection layer and then gathered at the center position of the condensing trough. The curing device has the advantages that as the condensing trough is arranged at the rear end of the condensing lens, a quartz tube is disposed into the condensing trough, and the light rays are reflected and focused to the center of the quartz tube through the condensing trough, the light intensity loss can be effectively reduced, all faces of the optical fibers can be irradiated through only one light source, power consumption is reduced accordingly, the cost is reduced, besides, the curing effect is good, less heat is generated as fewer light source is adopted, and the device of a heat dissipation is reduced in a disguised mode.

Description

technical field

[0001] The invention relates to an optical fiber cross-linking device, in particular to a curing device for coating UV resin on an optical fiber. Background technique

[0002] Irradiation cross-linking technology refers to the realization of cross-linking reaction of macromolecules by chemical means (such as adding cross-linking agent) or physical methods (such as irradiation), so that linear polymers become polymers with three-dimensional space network structure. technology. It has the characteristics of saving money, time and versatility, and is widely used in the field of optical fiber manufacturing. In the prior art, the ultraviolet light irradiation light crosslinking device mostly adopts a medium mercury lamp to generate ultraviolet light irradiation, the life of the mercury lamp is short, and with the increase of the use time, the intensity of ultraviolet light decays quickly, and it will generate a large amount of light. Heat usually needs to be equ...
