Abstract
A laser control device in a photo-cured stereoscopic model comprises a base (1), a laser filter plate (2), a base fixing screw (3) and a laser filter plate fixing screw (4), wherein the laser filter plate (2) and the base (1) are fixed on a laser fixing plate after being matched through a slide groove. The laser control device is characterized in that a 4mm round hole is reserved on the laser filter plate (2), halo around a light spot is changed by adjusting position of the laser filter plate (2) on the base (1), so that size of the light spot of a laser can be controlled. The laser filter plate and the base are fixed between a second reflector mirror and a scanning vibration mirror outside the laser after being assembled, and by adjusting positions, the size of the light spot irradiated on a resin liquid surface is guaranteed, thereby manufacturing requirements of photo-cured products are met, photosensitive resin waste can be avoided and manufacturing cost is reduced.
Description
Technical field
The utility model relates to the control technology of laser size in the rapid shaping, especially about laser control apparatus in a kind of photocuring three-dimensional contouring.Thereby improve the performance of photocuring three-dimensional contouring product, and can effectively control the cost of manufacture of photocuring three-dimensional contouring product.
Background technology
Rapid shaping (RP) technology is the advanced manufacturing technology that the eighties grows up, and the RP technology is integrated growing up on the basis of Modern CAD/CAM technology, laser technology, computer numerical control technology, elaborate servo actuation techniques and new material technology.Its basic principle be under the control of computer by the material accumulation method directly with the quick generating three-dimensional physical model of CAD mathematical model, wherein the process of comparative maturity is photocuring three-dimensional contouring (SLA-Stereolithography).This technology is take photosensitive resin as raw material, be the point by point scanning of track liquid towards resin with the Ultra-Violet Laser under the computer control by the profile of predetermined part each minute layer cross section, make the thin resin layer that is scanned the district produce photopolymerization reaction, thereby form a thin layer cross section of part.Complete when one deck curing, travelling table applies the new liquid resin of one deck at the resin surface that originally was cured again and solidifies in order to carry out lower one deck scanning.New one deck that solidifies is bonded on front one deck securely, so repeats until whole product prototype is made complete.The characteristics of photocuring three-dimensional contouring (SLA) are " layering manufacturings; successively stack ", are similar to mathematical integral process, need not to prepare in the situation of any mould, cutter and tooling fixture, directly accept product design (CAD) data, produce fast exemplar or the model of new product.The application of this technology can be shortened construction cycle, reducing development cost, the raising development quality of new product greatly.
But solidify discovery in three-dimensional contouring (SLA) making in actual light, after using for a long time, because laser instrument internal factor, the laser of launching from laser instrument is after the process reflection of scanning galvanometer, the hot spot that is radiated on the resin liquid level can become large, around hot spot, form halation, its halation size reaches 10mm, and above (the preferred outside diameter value of general laser facula is 0.12mm, and around the hot spot there be about halation 4-5mm class, under the irradiation of this sizes values laser, the performance of photocuring product is best), so cause photocuring three-dimensional contouring (SLA) product strength inadequate, surperficial thickness, the appearance and size of product is affected, no longer accurate, and resin liquid level forms thin film around the product, and the film resin of formation can not reclaim use again, can only pull out from liquid level and throw away, the moulding resin waste, and photosensitive resin generally all is imported material, and is expensive, and every gram is about 2 yuan of RMB approximately, large-area film has improved the cost of Quick formed part.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide laser control apparatus in a kind of photocuring three-dimensional contouring, is at the outside device that changes its spot size of laser instrument, namely guarantees the specification requirement of product, can reduce cost again.
The technical solution adopted in the utility model is: laser control apparatus in the photocuring three-dimensional contouring, comprise pedestal, laser filter plate, pedestal hold-down screw and laser filter plate hold-down screw, described laser filter plate and pedestal are fixed on the laser instrument fixed head after cooperating by chute; It is characterized in that: the 4mm circular hole is arranged on the laser filter plate, adjust by the position of laser filter plate on pedestal, change the halation of hot spot border, reach the effect of control laser instrument hot spot size.
Described laser controlling is filtered and the material of pedestal all is the 45# steel.
The utility model structure, be fixed on after laser filter plate and the pedestal assembling between outside second speculum of laser instrument and the scanning galvanometer, the circular hole that a 4mm is arranged on the laser filter plate, pass through position adjustments, see through the laser center of speculum by the circular hole on the laser filter plate, the laser filter plate itself blocks laser unnecessary halation all around, guarantee to be radiated at the size of hot spot on the resin liquid level, thereby the making requirement of photocuring product, and can avoid unnecessary photosensitive resin waste, reduce cost of manufacture.
Description of drawings
Fig. 1 is assembly structure schematic diagram of the present utility model.
Fig. 2 is the utility model base construction schematic diagram.
Fig. 3 is the utility model laser filter plate structure schematic diagram.
Among the figure: 1 pedestal, 2 laser filter plates, 3 pedestal hold-down screws, 4 laser filter plate hold-down screws.
The specific embodiment
As shown in Figure 1, laser control apparatus in the photocuring three-dimensional contouring is comprised of laser filter plate 2, pedestal 1, pedestal hold-down screw 3 and laser filter plate hold-down screw 4.Laser filter plate 2 and pedestal 2 are fixed on the laser instrument fixed head 2 after cooperating by chute.The material of laser controlling filter 2 and pedestal 1 all is the 45# steel.
As shown in Figure 2, be pedestal schematic diagram of the present utility model.Pedestal 1 is provided with pedestal fixing screw hole and laser filter plate fixing screw hole.
As shown in Figure 3, be laser filter plate schematic diagram of the present utility model.Because laser instrument hot spot border halation diameter is 4～5mm, so the 4mm circular hole is arranged on the laser filter plate 2, adjust by the position of laser filter plate 2 on pedestal 1, change the halation of hot spot border, reach the effect of control laser instrument hot spot size.
At first, the line cutting processing goes out the appearance profile of pedestal 1 and laser filter plate 2, and then line cutting processing place mating groove between the two, requires both slide blocks to cooperate.On pedestal 1, process pedestal fixing screw hole and laser filter plate fixing hole with drilling machine.The laser filter plate is inserted in the mating groove of people's pedestal, again the two is placed on the laser instrument fixed head between the second speculum and scanning galvanometer, laser power supply is opened, make laser pass through circular hole on the laser filter plate, adjust the position of pedestal and laser filter plate by observing hot spot in the shape (circle) of resin liquid level; After adjusting end pedestal is fixed at the laser instrument installing plate with the pedestal hold-down screw, the shape that observe hot spot on the resin liquid level this moment again, if position inaccuracy, can control by the laser filter plate of adjusting in the pedestal chute, after after adjusting, with laser filter plate hold-down screw laser filter plate and pedestal are fixed at last.
Its course of work: laser is launched from laser instrument, through passing through the circular hole on the laser filter plate in this utility model behind two mirror lens, arrives resin liquid level by scanning galvanometer at last again, makes product by the motion of scanning galvanometer.
