Description
Technical field
The utility model relates to mechanical manufacturing field, particularly the liquid crystal display formula 3D printer of the high and working stability of a kind of efficiency.
Background technology
At present, because 3D printer makes the manufacture of part more quick, 3D printer is more and more widely used in manufacturing industry.The basic forming thought that 3D prints is layering manufacture, successively superposes and then obtains 3D solid.Light-cured resin 3D printer mainly has two kinds of forms in the market: a kind of is to utilize galvanometer to control the technical grade 3D printer that laser carries out a line sweep; A kind of is to utilize projecting apparatus or liquid crystal display to carry out the desktop type 3D printer of face exposure curing resin.
The technical grade 3D printer that galvanometer control laser carries out a line sweep is the scanning pattern that galvanometer is controlled laser, one deck is solidified in laser scanning, in the distance of a bed thickness of vertical direction decline, (workbench is driven ball-screw rotation and is moved by servomotor workbench, kinematic accuracy is high, and each bed thickness is about 0.05-0.1mm).After workbench declines, scraper plate is planar driven by servomotor, is coated with paving resin.Scraper plate was scraped after one deck, and laser scans again, and so circulation, until finish.The defect of this kind of equipment has: due to the application of galvanometer (needing import), laser instrument, cause whole equipment price high (more than 500,000); Dotted line long-acting rate sweep time is low; Due to laser instrument, galvanometer, environmental requirement is high to external world, need working space be set separately, installs an air-conditioner, the equipment such as dehumidifier.Also have existing scraper plate will scrape sword for increase resin blade coating effect and design to obtain very little very thin (as Fig. 1), cause difficulty of processing to strengthen and easy damaged, easily flange is turned, and working life shortens.
The desktop type 3D printer that utilizes projecting apparatus or liquid crystal display to carry out face exposure curing resin all adopts below light source is placed on, on workbench, puts, and exposure curing one deck, screw mandrel drives the rise height of a bed thickness of workbench.Because move up workbench, for (scribbling silica gel) at the bottom of the resin and resin storage tank that make to have solidified is separated, machinery requirement has the action of " coming unstuck ", and common " coming unstuck " form has two kinds: one, resin storage tank moves left and right; Two, resin storage tank swings up and down.No matter which kind of action, has potential danger while coming unstuck, and tears, the poor staggered floor etc. that causes of positioning precision when as separated with silica gel (bottom resin storage tank) in curing resin layer.
Also have the lifting driving of the workbench of existing 3D printer all to use two guide rails (as Fig. 2), the introducing of two guide rails 11, must cause the requirement to the depth of parallelism, has increased the difficulty of assembling, has reduced efficiency, and has increased cost.
Summary of the invention
The utility model provides a kind of liquid crystal display formula 3D printer, has formed precision high, and cost is low, the advantage that operating efficiency is high.
In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:
A liquid crystal display formula 3D printer, comprises for holding the resin storage tank of photosensitive resin, in described resin storage tank, be provided with workbench, workbench is connected with upright driving mechanism, be positioned at workbench directly over be provided with liquid crystal display, resin storage tank top is provided with scraping plate mechanism.
Described upright driving mechanism comprises the tripod of connecting working table and the vertical ball-screw of driving tripod vertical motion, and vertically ball-screw is connected with the first servomotor.
Described scraping plate mechanism comprises scraper plate and drives the transversal driving mechanism of scraper plate transverse movement.
Described scraper plate is strip, and two side bottoms of scraper plate are provided with scrapes sword, and the cross section of scraping sword is right angled triangle.
Described transversal driving mechanism comprises the horizontal ball-screw that drives scraper plate transverse movement, and transverse ball lead screw is connected with the second servomotor.
In described resin storage tank, be provided with liquid level sensor and liquid level floating block.
Described liquid crystal display is high brightness liquid crystal display, and liquid crystal display is provided with for transmitting the data-interface of data.
The utility model is with respect to the advantage of prior art: liquid crystal display is positioned at workbench top, and workbench, to decline, can be used scraper to be coated with paving in print procedure, guaranteed surface quality and the precision of printout, there will not be staggered floor, comes unstuck and tear phenomenon; The use of high brightness liquid crystal display is shortened the time for exposure, has reduced cost, according to every layer of time for exposure of different resins be 1-10s, improve photocuring efficiency; Workbench drives ball-screw to move by servomotor, can reach often thick 0.005-0.015mm layer by layer; Scraper plate drives by servomotor, and kinematic accuracy is high; The cross section of scraping sword is right angled triangle, increases the thickness of scraping sword, improves its stiffness and strength, has extended service life, and easy damaged is not scraped sword, has saved Machining of Curved Surface simultaneously, has reduced processing cost; Without guide rail assembling, reduce assembly difficulty, raise the efficiency.
