The monomode optical fibres in the photocuring small-structure optical fibre bundle launcher can generate fine laser faculas, the precision of patterns is guaranteed without the problems of dispersion and focusing as well as light scattering; besides, an optical fibre dot matrix pattern belongs to single exposure shaping, and the pattern has the advantages of small deformation, high speed and high quality in the shaping process.
Description
Technical field
The utility model belongs to fiber optic bundle emission device technique field, is specifically related to a kind of photocuring small structure fiber optic bundle emission device.
Background technology
The method of laser radiation photosensitive resin curing molding has point by point scanning and face exposure.Point by point scanning is that the hot spot that becomes with laser focusing is a little, and under the driving of mobile device, with the quick resin face of hot spot scan light, to draw required small structure pattern, its quality depends on scanning light spot and mobile device.Form meticulous hot spot, need to be equipped with and to filter astigmatism and fine-focused optical system.Owing to limited by the kinematic accuracy of mobile device and sweep velocity, pattern easily deforms in scanning process, and speed is slow, efficient is low.The face exposure is once to produce a complete small structure pattern, and moulding in a photosensitive resin face irradiation, need not any mobile device; Have the advantages that speed is fast, efficient is high, distortion is little.Pattern is generally formed by liquid crystals transmit and low-light catoptron, and it makes the precision that has determined to generate pattern with control accuracy.Fine pattern also requires dispersionless even directional light, and necessary energy convergent-divergent and focusing; Need to be equipped with accurate optical system.Because controlling unit is many, so the pattern quality is limited.Be necessary to seek better small structure molding mode.
Summary of the invention
The purpose of this utility model provides a kind of photocuring small structure fiber optic bundle emission device, solved the not high problem of existing optical system imaging quality, inject by the laser of controlling every optical fiber, produce fiber optic point system of battle formations case at exit end, with this patterned illumination photosensitive resin face, just plastic required small structure.
The technical scheme that the utility model adopted is, a kind of photocuring small structure fiber optic bundle emission device, comprise laser array by at least two laser constitutions, also comprise the fibre bundle of forming by at least two single-mode fibers, each laser instrument fuses mutually with corresponding single-mode fiber, and the other end of fibre bundle is provided with exit end.
The beneficial effects of the utility model are that single-mode fiber can produce meticulous laser facula, has both guaranteed the pattern precision, does not have chromatic dispersion, focusing and astigmatic problem again.Fiber optic point system of battle formations case belongs to the single exposure moulding, and that pattern is out of shape in forming process is little, speed is fast, quality is high.Benefit from the development of fibre-optical drawing technology, the optical fiber dot matrix near diffraction takes place, has very high resolution.Though the optical fiber dot matrix can reach tens thousand of scales, the required small structure pattern of energy single exposure moulding, but the restriction of Stimulated Light device array scale when the size of small structure to be formed during greater than the optical fiber dot matrix, can be converted to it a series of fiber optic point system of battle formations cases earlier in order; Cooperate the running fix at intermittence of respective drive device, by width of cloth regeneration small structure pattern.This had both simplified the laser pattern generation system, had given full play to the effect of original drive unit again.
Description of drawings
Fig. 1 is the structural representation of the utility model photocuring small structure fiber optic bundle emission device;
Fig. 2 is the optical fiber dot matrix synoptic diagram of the utility model photocuring small structure fiber optic bundle emission.
Among the figure, 1. laser array, 2. fibre bundle, 3. exit end, 4. optical fiber dot matrix, 5. laser instrument, 6. single-mode fiber.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The structure of a kind of embodiment of the utility model photocuring small structure fiber optic bundle emission device, as shown in Figure 1, comprise the laser array of forming by a plurality of laser instruments 51, also comprise the fibre bundle of forming by a plurality of single-mode fibers 62, each laser instrument 5 all with fibre bundle 2 in corresponding single-mode fiber 6 fuse; Laser instrument 5 is responsible for laser and is injected, and single-mode fiber 6 is responsible for Laser Transmission.As shown in Figure 2, fibre bundle 2 is agglomerated into optical fiber dot matrix 4 at exit end 3 places, and the size of optical fiber dot matrix 4, shape and resolution depend on the fibre-optical drawing technology, and the exit end 3 at optical fiber dot matrix 4 places needs Precision Machining, to guarantee the laser vertical outgoing.Control laser array 1 can form fiber optic point system of battle formations case at exit end 3, can show as unidimensional laser pattern, by irradiation photosensitive resin face curing molding.If small structure can be converted to it a series of fiber optic point system of battle formations cases earlier in order greater than the size of optical fiber dot matrix 4.Generate by laser array 1 control pattern, cooperate location, mobile device accordingly, just can be by the required small structure of width of cloth regeneration on photosensitive resin.
