A computer controls an array switching and scanning strip to transversely move to complete light-curing shaping of one level. The absorption peak wavelength of light-cured resin is consistent with the strong wavelength of the light source. The present invention has the characteristics of low cost, high precision, high moulding efficiency and simple manufacturing process.
Description
The present invention relates to the curing molding method and the device thereof in manufacturing technology field, a kind of specifically non-laser light source line sweep photocuring moulding method and device thereof can be applied to the quick manufacturing of the model and the exemplar in machinery, instrument and meter, computer, automobile, space flight and aviation, building, medical engineering field.
Rapid shaping technique (RP) is a novel concept of manufacturing technology, and its adopts material forming principle that adds up, and need not cutter, and frock by number of ways moulding 3D solid, is a kind of development of manufacturing direction that is rich in vitality.
At present many kinds are arranged, mainly contain photocuring method (Stereolithography), layered manner (LOM), sintering process (SLS), molten weldering method (FDM), 3D print process (3D-Printer) etc. with the quick molding method of developing.Wherein best with the combination property of photocuring, the sales volume maximum of commodity machine, its occupation rate of market has reached 70%, its main feature is the formed precision height, surface smoothness is good, stock utilization is high, shaping speed is fast, can make hollow and fine structure etc., thereby becomes rapid shaping user's preferred unit.The 3D Systems company of the U.S., the Xi'an Communications University of CMET Inc., German EOS company and China of Japan are the main units of research uv equipment and technology.Owing to use low-power ultraviolet laser device, make rapid shaping not have heat, friction, no flue dust.
Existing photocuring method mainly is to utilize photosensitive resin to be subjected to Ultra-Violet Laser irradiation curing principle to carry out the material moulding that adds up.It needs ultraviolet laser device and high-quality scanning system, and the moulding of each aspect needs scanning system to carry out the filling of graph outline scanning and entity on the photosensitive resin liquid level.Its cost and usage charges are all very high, and as laser instrument, have only 2000 hours specified service life, the expense of scanning system is higher, formed precision is subjected to the scanner accuracy limitations, and it is fair to make mini Mod, if be used to make large-sized model, then the distortion that causes of scanning patter is just very big, be difficult for revising, very big to the precision influence of model, in addition, because every layer curing all wants the irradiation of pointwise to solidify, make that also shaping efficiency is difficult to improve.
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, proposed a cheapness more, accurate and method of photocuring moulding efficiently and device thereof.
Technical scheme of the present invention is: non-laser light source line sweep photocuring moulding method, be characterized in, with the non-laser uviol lamp of wavelength 230mm～350mm as the light source that causes photocuring reaction, by elliptic reflector optically focused, transport light to light output end by optical fiber, by the photoswitch bar light-cured resin is carried out scanning moulding, scanning system uses the transverse movement of photoswitch bar to realize, the high-amplitude wave long value of the absworption peak wavelength of light-cured resin and light source is consistent.
Described photoswitch bar adopts non-laser uviol lamp as light source, makes the light transmission strip of an one dimension, depict switch element on the bar, each switch element all is a photoswitch, by these switch elements of computer control, forms the figure of one dimension, close the transverse movement of switch bar, constituted the formation of another dimension figure again, both are synthetic, the transverse movement of switch bar, photoswitch in the photoswitch bar is being made corresponding switch, thereby constitutes two dimensional optical scanning.
Some other characteristics of the present invention are that elliptic reflector is cylindroid or oval spherical reflector, plating ultraviolet reflectance film on the reflecting surface.
The photoswitch bar has transmitance more than 95% to ultraviolet light, carves the leaky hole of 0.1mm on the photoswitch bar, and the break-make of light is controlled at more than the 50Hz.
The photoswitch bar is when transverse movement, and computer will be controlled the break-make of light according to scan-data, once finishes the scanning of an aspect.
Realize the device of non-laser light source line sweep photocuring moulding method of the present invention, comprise light source and sweep mechanism, be characterized in: light source 2 places on the focal position of elliptic reflector 1, light receiving device 3 places on another focal position of elliptic reflector 1, ultraviolet light is through elliptic reflector 1 and light receiving device 3 optically focused, transport light on the switch bar 5 by optical fiber 4, switch bar 5 is supported by two guide rails 6, can realize motion scanning on the liquid level on the resin 7, the photoswitch 8 on the photoswitch bar 5 is by the break-make of computer control light.
Advantage of the present invention is, resolution ratio height, precision height, and low, the easy realization of cost, the photoswitch bar walks just can finish for one time the scanning of an aspect on liquid level, and shaping speed also improves, and especially more has superiority making on large-sized make-up machine.
Accompanying drawing is to realize device schematic diagram of the present invention.
The present invention is described in further detail below in conjunction with drawings and Examples.
Embodiment: referring to accompanying drawing, this device comprises: 1. elliptic reflector; 2. light source; 3. light receiving device; 4. optical fiber; 5. photoswitch bar; 6. guide rail; 7. light-cured resin; 8. photoswitch.
