Description
(1) technical field
The utility model relates to a kind of pair of ultraviolet lamp optical fiber coating solidification equipment, is used for the ultra-violet curing of miniature fiber wire-drawer-tower or similar filament surface coating.Belong to the optical fiber technology field.
(2) background technology
The effect of fibre coating is that the protection optical fiber surface can not be subject to the impact of physical abuse and moisture and keep its original intensity.Therefore coated material is the ultraviolet sensitivity material normally, in the process of drawing optical fibers, adopt uv oven to make to pass the coating of the optical fiber that scribbles coating of ultra-violet curing device to be cured through behind the ultraviolet light irradiation.Therefore the curing at the drawing process floating coat has larger impact to fiber strength and quality.
In the coating procedure, another factor that affects fiber strength is the bubble in the coating.The generation of bubble mainly is because in the wire drawing, optical fiber position in mould is offset, so that the half-moon-shaped liquid level run-off the straight of coating formation, and the increase that is under pressure of angle smaller side, gas is brought in the coating by optical fiber easily.Perhaps coating temperature variation applies the factor such as pressure surge and all can produce bubble in coating.Bubble in the coating has reduced between coating and the coating and the bonding force between coating and the bare fibre.And the existence of bubble has increased coating in the under tension situation, and the possibility that cracks finally causes fiber strength to reduce.
According to the actual fiber production method, be widely used at present the technological method of photopolymerization.Utilize ultraviolet radiation so that light trigger is excited into active body (free radical or positively charged ion).The two key reactions of C=C in this active body and prepolymer and the monomer form growing chain.This growing chain further reacts, and forms longer polymer chain.If have multitube energy degree polymkeric substance or monomer to exist, will produce crosslinking structure, coupling and the disproportionation of last active body make reaction terminating.Therefore, in curing oven, pass into a certain proportion of rare gas element, prevent the inhibition that oxygen increases polymer chain, improve solidification effect.
The patent No. is that 201120051918.0 utility model patent discloses a kind of ultraviolet curing lamp with focusing function, lamp holder is fixed on the front end of a focus drum, be provided with focusing lens in lamp holder the place ahead, focusing lens and focus drum are fixed, and, focus on the focus at a distance after the light source line focus eyeglass that lamp holder sends focuses on.Be radiated on the device to be solidified after the ultraviolet source line focus, make the luminous energy on unit time, the unit surface stronger, can within the shorter time, reach required solidification intensity.The patent No. is that the patent of invention of 200610053960.X discloses a kind of UV solidifying radiation device, comprise the high-pressure discharge light source, ellipsoid light harvesting speculum, light pipe and the projection lens set that set gradually, the luminous point of high-pressure discharge light source is positioned at the first focus place of ellipsoid light harvesting speculum, ellipsoid light harvesting speculum and light pipe incident end face are provided with condensor to optical axis between projecting lens apparatus and the illuminated workpiece surface.The ultraviolet light incident side of photoconductive tube is in the second focus area of ellipsoid light harvesting reflective mirror, but the processed surface of direct viewing workpiece is convenient to workpiece is carried out accurate adjustment, makes the ultra-violet curing irradiation light of its aligning.Along with the raising of technology, drawing speed improves constantly in producing at present, and optical fiber only is shorter and shorter in the residence time of curing oven.For guaranteeing to apply the solidification effect of rear optical fiber, require curing oven that enough ultraviolet luminous energy can be provided, satisfy light trigger and activate into the needed energy of active body.Above-mentioned existing ultra-violet curing technology all is for the device uv irradiation of realizing single-point type solidifies the luminous energy ethod of remittance adopted the ellipsoid minute surface, and the utility model technical patent is in addition improved for the deficiency that overcomes existing single ultraviolet lamp curing oven medium ultraviolet luminous energy irradiation intensity.The shape of the speculum that adopts in the optical fiber coating solidification equipment described in the utility model is the plane of reflection that mutually is combined to form by two identical cylinder ellipses of geometric parameter, a focus of two cylinder ellipses overlaps, Glass tubing is positioned on the focus of this coincidence, and two ultraviolet lamps are distributed in the both sides of Glass tubing, be positioned at separately another focus place of two cylinder ellipses, with the energy centralization of two ultraviolet sources on the coat of optical fiber surface.This solidification equipment has strengthened coating material uv irradiation intensity owing to used two symmetrical ultraviolet lamps to be cured simultaneously, has shortened set time, helps to improve drawing speed.
