Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to the overall structure schematic diagram that Fig. 1, Fig. 1 are a kind of detailed description of the invention provided by the utility model.
In a kind of detailed description of the invention provided by the utility model, the optical fiber coating LED solidification equipment of optical fiber resin curing oven mainly includes quartz glass tube 2, installs tubing string 3 and LED 4.
Wherein, quartz glass tube 2 is one of parts of solidifying of the material coatings such as the resin to optical fiber 1 commonly used in the prior art or ink.Quartz glass tube 2 quality is hard and transparency, light transmission are good, is adapted to the light of various frequency or wavelength period.General, quartz glass tube 2 is cylindric, and optical fiber 1 is just arranged in quartz glass tube 2.Concrete, optical fiber 1 is vertically tightened and is elongated at the two ends within quartz glass tube 2, and can uniform motion wherein.Optical fiber 1, before entering in quartz glass tube 2, passes through the processing of resin coating production equipment, at materials such as its surface-coated last layer resins.In the solidification process of resin, optical fiber 1 is at the uniform velocity by adapting to glass tubing 2 under the drive of driven equipment, and period completes the solidification process of resin.
Installing tubing string 3 and be arranged on the outside of quartz glass tube 2, general, installing tubing string 3 is circular tube shaped, with the mating shapes of quartz glass tube 2.Certainly, if quartz glass tube 2 is square, then it is also square for installing tubing string 3.And, the tubing string 3 axial distribution along quartz glass tube 2 is installed, and by its cincture, it is believed that install tubing string 3 to be enclosed within the surface of quartz glass tube 2, or quartz glass tube 2 is inserted in the inside installing tubing string 3, certainly, both are close to the most mutually, but there is a determining deviation between the outer wall of quartz glass tube 2 and the inwall installing tubing string 3.
The medial wall installing tubing string 3 is provided with multiple LED 4, this LED 4 has specific operating frequency, the light of specific wavelength can be sent, in this utility model, this LED 4 can launch ultraviolet light, meanwhile, the top layer of optical fiber 1 is also coated with can occur the material layer of chemical reaction when running into this kind of characteristic frequency ultraviolet light, such as resin bed or ink layer etc., produce solidification effect.The quantity of LED 4 is depending on the length, diameter of quartz glass tube 2, for ensureing that optical fiber 1 is during by quartz glass tube 2, the materials such as the resin of its surface-coated can synchronize solidification, ultraviolet light produced by each LED 4 is required to cover quartz glass tube 2, ultraviolet light so can be made to enter in quartz glass tube 2, carry out optical fiber 1 comprehensive irradiating without dead angle.The most preferably, in order to improve each LED 4 solidification uniformity coefficient to the coating material of optical fiber 1, can each LED 4 be axially uniformly distributed as many groups along quartz glass tube 2, simultaneously according to the light radiation angle of conventional LED 4, the spacing of two adjacent groups LED 4 can be between 10～15mm, such as 12mm etc..Further, among each group of LED 4, each LED 4 can be uniformly distributed around the circumference of quartz glass tube 2, light radiation angle also according to conventional LED 4, the angle of two adjacent LED 4 can be set between 90 °～120 °, when such as angle is 90 °, the quantity of each group of LED 4 is four；And angle is when being 120 °, the quantity of each group of LED 4 is three.
It should be noted that each LED 4 is random in the distribution installed on tubing string 3, only need to cover the outer wall of quartz glass tube 2.
In sum, optical fiber coating LED solidification equipment provided by the utility model, installation tubing string 3 is set outside quartz glass tube 2, multiple LED 4 by arranging on installation tubing string 3 produce ultraviolet light again, thus radiate into the optical fiber 1 in quartz glass tube 2, the material generation chemical reactions such as the resin with optical fiber 1 surface-coated so that resin curing molding.Compared to prior art, owing to LED belongs to cold light source lamp, not only energy consumption is low, and luminous efficiency is high, caloric value is the least in addition, therefore in the resinous coat solidification process of optical fiber 1, it can be avoided that the impact that heat accumulation is on solidification rate, improve the curing efficiency of optical fiber coating resin.
In addition, the solidification rate of resin and uniformity coefficient are vulnerable to outside air impact (predominantly oxygen, when temperature is higher, easily react with resin), for this, the present embodiment is provided with sealing plate 5 at the two ends that installation tubing string 3 is axial and carries out hermetic seal to installing tubing string 3, thus stops the harmful effect of air.
Further, the present embodiment is also provided with pore 6 on sealing plate 5, and this pore 6 is mainly used in importing or deriving nitrogen, thus as catalyst in resin curing process, the environment sufficient by nitrogen improves the curing reaction speed between ultraviolet light and resin, accelerates reaction process.Meanwhile, the environment that nitrogen is sufficient also significantly reduces the content (oxygen concentration≤100ppm) of oxygen, it is to avoid resin is oxidized when temperature is higher.
Moreover, length in view of optical fiber 1 is generally large, the resin curing process persistent period is the longest, even and if LED 4 caloric value is little, but when quantity is more, still can accumulate certain heat long lasting for after running, in order to dispel the heat each LED 4, the present embodiment is provided with in installing tubing string 3 and is exclusively used in the cooling system dispelling the heat it.
As in figure 2 it is shown, the concrete structure schematic diagram that Fig. 2 is the cooling system in Fig. 1.
Concrete, this cooling system mainly includes heat-conducting layer 301 and Water cooling heat exchanger 302.Wherein, heat-conducting layer 301 is close to install the medial wall of tubing string 3, and each LED 4 is arranged at installing the medial wall of tubing string 3, and therefore when LED 4 produces heat, major part heat will be directly delivered on heat-conducting layer 301.Water cooling heat exchanger 302 is connected with heat-conducting layer 301, and the heat that such heat-conducting layer 301 is absorbed will diffuse to the external world by Water cooling heat exchanger 302.Certainly, when LED 4 being dispelled the heat by the way of water-cooled, also installing, on tubing string 3, water inlet and outlet need to be set.Concrete, for ensureing the Water cooling heat exchanger 302 heat exchange efficiency to heat-conducting layer 301, can be selected for the heat dissipating fluid that degree of purity is higher, such as can circulate in Water cooling heat exchanger 302, to improve radiating efficiency with pure water or deionization water or other fluid.
This utility model also provides for a kind of optical fiber resin curing oven, and including casing 7 and the optical fiber coating LED solidification equipment being arranged in casing 7, wherein, this optical fiber coating LED solidification equipment is identical with foregoing teachings, and here is omitted.
