Description
Technical field
The utility model relates to and a kind ofly tiltedly pulls out assembly for 3D printing equipment, belongs to printing device technical field.
Background technology
3D printing equipment is also known as three-dimensional printer, and be a kind of machine adopting accumulation manufacturing technology (i.e. RP technique), its principle is that data and raw material are put in 3D printer, and machine is created product from level to level according to program.At present, 3D printing equipment comparatively commonly adopts the SLA stereosopic printing of face forming technique (also known as stereolithography, light chisel), specific works principle is: fill with liquid photocurable resin in liquid bath, can solidify in setting regions under the light-wave irradiation of doses, during shaping beginning, workbench is on liquid level, bottom its lower surface and liquid bath, the spacing of dianegative upper surface is the thickness that individual layer prints, the instruction that laser after focusing presses computer under liquid level is irradiated, after one deck has irradiated, (face forming technique is that whole cross section is solidified simultaneously) is just solidified in irradiated place simultaneously, not irradiated place remains liquid resin.Then translation workbench (moves on to transposition platform from irradiation platform, wherein, transposition platform is lower than irradiation platform), the cured layer be close to bottom liquid bath is departed from completely, then crane drives workbench to rise a layer height again, is covered with again one deck resin above, to carry out second layer irradiation, one deck of new solidification is bonded on front one deck securely, so repeats until 3D article complete.When the 3D printing equipment of this structure solidifies, because the tension force of dianegative is very large bottom cured layer and liquid bath, print platform cannot vertically pull-up, and then need two planes with certain altitude drop to carry out translation, cause transverse machine spatial area larger, not only take up room but also waste liquid photocurable resin, and repeated translation, make the film of the dianegative upper surface of irradiation platform because frictional force is easy to damage, life-span is shorter, generally can only print 8000-10000 level just must change, not only add replacing operation but also increased considerably printing cost.
In view of this, the present inventor studies this, develops specially a kind ofly tiltedly to pull out assembly for 3D printing equipment, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind ofly tiltedly pulls out assembly for 3D printing equipment; easily depart from bottom the cured layer of print platform and resin frame by tiltedly pulling out mode; better protection resin frame bottom film is from frictional force; extend its service life; and it is less that the area of plane of resin frame can be made to accomplish, and then make the horizontal volume of whole 3D printing equipment less, lighter.
To achieve these goals, solution of the present utility model is:
A kind ofly tiltedly pull out assembly for 3D printing equipment, comprise mounting bracket, and by hollow support frame that connector is flexibly connected with mounting bracket, described carriage is provided with for holding the resin frame printing solution, the bottom of described resin frame is dianegative, be provided with a pull bar further bottom the side that described carriage is relative with connector, pull bar is connected with drive motors, by the rising of pull bar or decline carriage can be made to rotate along connector.
As preferably, the described connector tiltedly pulling out assembly is rotating shaft or hinge.
As preferably, the both sides of described carriage are provided with gathering sill, and the bottom of resin frame is provided with corresponding guiding rib, by the cooperation of gathering sill and guiding rib, make resin frame slip into along gathering sill or to skid off carriage.
As preferably, the bottom of described pull bar is provided with a limit sensors, and the middle part of pull bar is provided with a postive stop baffle, and pull bar top is fixedly connected with carriage, lower end is through the spacing hole of mounting bracket, postive stop baffle is positioned at the below of spacing hole, and when arriving limit sensors bottom pull bar, drive motors quits work, stop lower turn further of carriage, when postive stop baffle upper surface touches spacing hole lower surface edge, drive motors also quits work, and stops the upper further of carriage to turn.
Above-mentionedly tiltedly pull out component operation principle: after the projection of exposure mechanism terminates, the pull bar of Xie Ba mechanism starts action, while carriage is pulled down, resin frame also declines thereupon, cured layer starts to depart from dianegative in drop-down side, air slowly enters, when arriving limit sensors bottom pull bar, drive motors quits work, now the whole cured layer of print platform and dianegative depart from completely, print platform slowly rises, pull bar also slowly rises under the effect of drive motors, when carriage and resin frame return to horizontal level, drive motors quits work, now, postive stop baffle upper surface contacts with spacing hole lower surface.
Adopt and tiltedly pull out assembly, slowly drop-down by side, make to depart from completely bottom cured layer and resin frame, translation is not needed to increase the area of plane of resin frame, nor can because translation produces frictional force, can increase substantially the service life of film on resin frame dianegative, a general resin frame can print 40-50 ten thousand times.
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
