Description
Technical field
The present invention relates to resin coating apparatus and fast prototype making process for light-cured rapid prototype manufacture, belong to RP technique field.
Background technology
RP technique is a kind of cumulative formula forming technique based on discrete accumulation principle.The modern means such as its computer, laser, precision drive and numerical control, CAD (CAD) and computer-aided manufacturing (CAM) are integrated in one, according to the threedimensional model of constructing on computers, model or sample can directly manufacture a product within very short time.
Light-cured rapid prototype manufacturing process be take photosensitive resin as raw material, by the three-dimensional part model designing on computer, surface triangulation is processed, be stored as stl file form, it is carried out to layering processing, the two-dimensional silhouette information that obtains each layer cross section, generates scanning solidification path automatically according to these profile informations, by computer control Ultra-Violet Laser, makes its Layer by layer solidification moulding.After one deck solidifies, workbench moves down the distance of a bed thickness, so that apply again at the resin surface being originally cured the liquid photosensitive resin that last layer is new, scraper strikes off the larger resin liquid level of viscosity, then work is solidified in the scanning of carrying out the coating of new one deck, so repeat, until the manufacture of whole product is complete.
Current resinous coat method has two kinds, and a kind of is negative-pressure adsorption-type coating process.The process that the method is carried out coating is: after one deck two-dimensional silhouette is solidified, the workbench distance of a bed thickness that declines, then adopt negative-pressure adsorption-type coating mechanism, realizes at cured layer upper surface and apply new liquid photosensitive resin.The method is owing to having certain interval between scraper edge and resin liquid level, when workpiece sinks, because the reasons such as the difficult mobile depression causing of resin viscous or the quick operation of scraper are as easy as rolling off a log, making scraper cavity lose negative pressure affects the workpiece uniformity that the new liquid photosensitive resin of cured layer upper surface applies, finally affects workpiece quality and cause product failure.While particularly making the larger workpiece of area of section, because be difficult to accurately control in the amount of resin that cured layer upper surface applies when the amount of resin in negative-pressure adsorption-type coating mechanism and device are mobile, easily make cured layer surface lack resin or be difficult to guarantee that its bed thickness precision causes coating procedure failure.Another kind is immersion coating process.The method exists workbench motion process consuming time more, and service working time is longer, causes the low deficiency that waits of make efficiency.
For solving above-mentioned deficiency, in China Patent No., be 2004100732595, within open day, be on April 6th, 2005, name is called the resinous coat making that " a kind of resin coating apparatus for photocurable quick shaping process " designed piston type workbench.The peristaltic pump of controlling by computer that this device comprises accumulator tank and is connected with accumulator tank, the shower nozzle that peristaltic pump is arranged with branch by pipeline is connected, under the shower nozzle of arranging in branch, be also provided with cylinder body and close-fitting by computer-controlled piston with cylinder body, the space that the upper surface of piston and the inner cylinder face of cylinder body form is as the resin storage tank that holds resin, in the upper end of piston and the opening of cylinder body is also provided with scraper plate and the transducer being connected with scraper plate in the position of same level and by computer-controlled supersonic generator.In manufacturing process, after one deck resin solidification completes, under the control of computer, the piston thick distance that sends behind, peristaltic pump extracts quantitative resin and in shower nozzle is sprayed onto resin storage tank under the control of computer from accumulator tank, after resin sprays well, computer controlled ultrasonic generator by transducer by vibration transmission to scraper plate, scraper plate along continuous straight runs strikes off action, complete the even coating work of resin bed, after product all completes, the top that piston rises to cylinder body ejects making.
