For guaranteeing the precision of photocureable rapid shaping product in forming height direction, need the precision of bonding layer thickness.Accurate bed thickness to be really guaranteed, the constant of liquid level position must be guaranteed.At present, guarantee liquid level position constant aspect, mainly adopt laser liquid-level measurement to compensate with sinker the method combining.Concrete methods of realizing is to adopt laser position sensors to detect the liquid level position in rapid molding device, utilize computer to analyze feedback information, then by computer-controlled electric machine rotation, drive the lifting of sinker in resin storage tank, thereby the liquid level realizing in moulding resin storage tank is constant.Sinker compensation mechanism mainly comprises bearing block, leading screw and support, and sinker is connected with the lower end of compensation mechanism.Rotatablely moving of motor is converted into the rectilinear motion up and down of sinker.
Conventional mode can guarantee that the position of liquid level is constant preferably at present, thereby has guaranteed the precision of molded article on forming height direction and length and width, but structurally must have sinker compensation mechanism, has increased the complexity of structure.
Meanwhile, the resin storage tank structure in the at present more conventional quick machine of photocuring is generally fixedly mounted on the below of cabinet.Because resin storage tank structure is non-dismountable, and in the process of photocureable rapid shaping, resin in resin storage tank only has a kind of, when if the sample of moulding needs multiple color, need the original resin in resin storage tank to emit, and resin storage tank is cleaned, then inject the resin that needs color, increase molding procedure, reduced shaping efficiency.
Utility model content
For resin storage tank fixed installation in above-mentioned prior art, and in this phenomenon of method that need adopt laser liquid-level measurement to combine with sinker compensation aspect liquid level position control, the purpose of this utility model is to propose a kind of novel tank level control system.It improves existing resin storage tank structure, and the resin storage tank after improvement can freely be dismantled from cabinet, and under the drive of elevating mechanism, can realize and moving up and down at vertical direction.Aspect liquid level control, saved sinker compensation mechanism, but control an elevating mechanism by a micro-machine, drive the resin storage tank in photocureable rapid shaping machine to move up and down in overall, thereby guarantee that the liquid level position in resin storage tank is constant, realize the constant distance between liquid level and laser instrument.
The technical solution of the utility model is, tank level control system in a kind of photocurable quick shaping process, comprise the work lifting platform, the scraper plate that are positioned at resin storage tank, and laser instrument and the galvanometer of resin storage tank top, described tank level control system also comprises that one for detection of the liquid level detection device of resin liquid level in resin storage tank, described resin storage tank bottom is seated on a resin storage tank elevating mechanism, makes resin storage tank can carry out elevating movement.
Further, described resin storage tank bottom has running gear.
Further, described work lifting platform carries out elevating movement by the lifting platform motor driving work lifting platform leading screw of working.
Further, described resin storage tank elevating mechanism comprises upper backup pad, main body installing plate, connecting rod, leading screw etc., resin storage tank bottom is seated on upper backup pad, and resin storage tank lifting motor drives the be dynamically connected bar linkage structure of upper backup pad and main body installing plate of resin storage tank leading screw band to realize the lifting of resin storage tank elevating mechanism.
Further, described resin storage tank leading screw also has handwheel.
Further, described running gear is roller.
Further, described liquid level detection device is laser liquid-level measurement device.
Resin storage tank, for splendid attire liquid photosensitive resin, is normally placed in the downside of photocureable rapid shaping rack body.In the bottom of resin storage tank, be provided with a running gear, fixed installation between this running gear and resin storage tank bottom, can realize resin storage tank and freely dismantle from cabinet.When moulding sample needs multiple color, can realize by changing resin storage tank the quick-replaceable of resin.
In the bottom of cabinet, be provided with Yi Ge liftable mechanism, this mechanism both can pass through its lifting of Electric Machine Control, also can manually control its lifting by handwheel.Resin storage tank is placed on the platform of elevating mechanism upper end after entering cabinet, can regulate the height of resin storage tank by adjusting elevating mechanism, thereby realize the adjusting of resin liquid level in resin storage tank.
Laser liquid-level measurement device is placed in the top of resin storage tank, detect in real time liquid level, when liquid level being detected and change, computer is controlled the electric machine rotation of elevating mechanism in time according to feedback information, realize resin storage tank part integral elevating, thereby guarantee the constant distance between resin liquid level and laser instrument.
The utility model beneficial effect is that it both can realize the quick-replaceable of resin storage tank, also can realize the adjusting of resin liquid level in resin storage tank, has compared with the prior art saved sinker compensation mechanism, and structure is simpler.

The specific embodiment
With reference to Fig. 1, the schematic diagram of Fig. 2, a kind of novel tank level control system in photocurable quick shaping process, it comprises a laser liquid-level measurement device that detects resin level, in the course of the work, in order to liquid level is detected in real time, a resin storage tank that is used for holding photosensitive resin, bottom surface at resin storage tank is provided with a running gear, be used for realizing moving freely of resin storage tank, the bottom surface of resin storage tank is connected with the upper backup pad of end face on elevating mechanism in installation process, moving up and down of elevating mechanism can drive resin storage tank realization to move up and down, in the upper end of resin storage tank, be provided with a scraper plate, in order to make the liquid level that produces disturbance tend to be steady within the shortest time in forming process, laser liquid-level measurement device in this system, scraper plate, the motor of elevating mechanism, work lifting platform motor, laser instrument is controlled by computer.
At the processing initial stage, if desired change the resin in resin storage tank, first, can be by the motor on elevating mechanism or handwheel, electronic or manual control by original resin storage tank by elevating mechanism reduce height, after under the effect of its running gear, from cabinet, depart from; Then, the new resin storage tank that fills required resin is pushed to cabinet, after under the effect of elevating mechanism, rise to the height needing.
In Stereolithography process, often complete after the processing of one deck, workbench drives the height of a bed thickness of workpiece decline, and to carry out next step processing, after whole workpiece machines, workbench drives workpiece to rise from liquid level.
Due in forming process, carrying out along with processing, resin liquid level height in resin storage tank can change, when laser liquid-level measurement device detects liquid level variation, information is fed back to computer, computer is processed feedback information, then make response, control the electric machine rotation on elevating mechanism, thereby it is highly corresponding to drive resin storage tank to rise, and realizes resin liquid level constant height in resin storage tank.
In Stereolithography process, when resin liquid level out-of-flatness being detected, the motion of computer control scraper plate makes the quick levelling of liquid level, guarantees that resin thickness to be processed is even, thereby processes even, the ganoid workpiece of bed thickness.
