Description
Technical field
Baffle plate is played present invention relates particularly to a kind of DLP3D printer.
Background technique
DLP3D printer successively solidifies photosensitive polymer by projector using digital optical processing technique (DLP)
Liquid becomes a kind of new rapid shaping technique, has the high and low cost of solidification rate, high score to be created that 3D printing object
The advantages that resolution, can satisfy market for part high-precision, surface high quality, the efficient requirement of processing, especially medical treatment,
The industries such as mold, bullion have huge prospect.
Currently, layer-by-layer cured final tache in DLP3D printer technology, molding separation is extremely crucial, and which determine whole
The quality of a part, and the finish on printing floor.However, DLP 3D printer currently on the market mostly uses seperation film
Mode improve separation and effect；Directly printing bottom plate is removed together with finished product, with blade or perching knife by product with
Mold carries out artificial separation by force, not only has damage to the flatness of template, but also be possible to cause product whole damage；Not
See dedicated effective pattern drawing mechanism.
Summary of the invention
The object of the invention is to artificial strong in order to solve the printed product of existing DLP3D printer and print bottom plate needs
The problem of row disassembly separation, takes time and effort, and disassembly process easily causes damage to product and template, providing one kind can be automatic
That realizes the DLP3D printer of molding separation plays baffle plate.
To achieve the goals above, the technical scheme adopted by the invention is that printing bottom plate can be followed to move together by setting
Dynamic movable floor, using return spring control movable floor gradually inclination and distortion in print procedure, so that active control is beaten
Print product is gradually separated with printing bottom plate；By the way that the controllable elastic range of return spring is arranged, make to print bottom plate in print procedure
In, it can be gradually reduced with printed product and be adhered to separate and influence normal printing job.
DLP3D printer automatic drawing bottom plate of the present invention, is made of locating support, movable floor and resin frame；It is described fixed
Turntable and locating rod are provided on the bracket of position；The side of the movable floor is provided with shaft, and the other side is provided with card slot；It is described
Movable floor is hingedly installed by the turntable of shaft side and locating support, and the other side is fitted to locating support by card slot
Locating rod on；Return spring is set in the locating rod of the locating support, the top of return spring is fixed, return spring
Bottom end is fixed on the bead of the card slot of movable floor；The resin frame setting is mounted on movable floor.
The bottom of the locating support is provided with adjusting stabilizer blade.
The locating rod is adjustable bolt structure.
The design line footpath of the return spring is 0.4-0.7mm.
The Deformation Height of the return spring is arranged according to the height of institute's printed product.
The beneficial effects of the present invention are: the entirety by controlling bottom plate in return spring beneficial margin moves up, certain
Altitude range and rotational angle range in, product is separated with bottom plate, avoid printing after product and printing bottom
Plate is adhered solidification, to ensure that the integrity degree of product；Reduce manpower workload, avoids manpower and remove to product and beat
Print the damage of bottom plate；It improves work efficiency and product quality, also support organization service life.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the mounting structure schematic diagram of the present invention on a printer；
Fig. 3 is printed product seperated schematic diagram of the invention；
In attached drawing: locating support 1, locating rod 12, return spring 13, adjusts stabilizer blade 14, movable floor 2, shaft at turntable 11
21, card slot 22, resin frame 3, workbench 4, printing bottom plate 5, product 6.
Specific embodiment
Below with reference to the specific implementation that the present invention will be described in detail of technical solution and attached drawing.
It is as shown in Fig. 1 DLP3D printer automatic drawing bottom plate of the present invention, by locating support 1, movable floor 2 and tree
Rouge frame 3 forms；Turntable 11 and locating rod 12 are provided on the locating support 1；The side of the movable floor 2 is provided with shaft
21, the other side is provided with card slot 22；The movable floor 2 is hingedly installed by the turntable 11 of 21 side of shaft and locating support 1,
The other side is fitted in the locating rod 12 of locating support 1 by card slot 22；It is set in the locating rod 12 of the locating support 1
Resilient spring 13, the top of return spring 13 are fixed, and the bottom end of return spring 13 is fixed on the edge of the card slot 22 of movable floor 2
On mouth；The setting of resin frame 3 is mounted on movable floor 2.
The bottom of the locating support 1, which is provided with, adjusts stabilizer blade 14.
The locating rod 12 is adjustable bolt structure.
The design line footpath of the return spring 13 is 0.4-0.7mm.
The Deformation Height of the return spring 13 is arranged according to the height of institute's printed product.
Embodiment
As illustrated in figs. 2-3, it setting of the DLP3D printer automatic drawing bottom plate of the present invention in product print procedure and answers
With:
1) locating support 1 is fixedly mounted on the workbench 4 of DLP3D printer, movable floor 2 is made to be in printing bottom plate
It is horizontal fixed to make locating support 1 by the adjusting stabilizer blade 14 of locating support 1, and adjusts 2 card slot 22 of movable floor for 5 underface
The height of side is in a horizontal position the card slot side of movable floor 2 with 21 side of shaft；
2) locating rod 12 for passing through locating support 1, according to the height of the height adjustment locating rod 12 of institute's printed product 6, choosing
The return spring 13 for selecting appropriate length, determines the deformation limit of return spring 13；
3) according to the height of the printing bottom plate 5 of the height for the product 6 to be printed setting DLP3D printer, resin frame 3 is put
It sets in the underface of printing bottom plate 5；
4) before the start-up operation of DLP3D printer, a certain amount of resin is poured into resin frame 3, printing starts；
5) in DLP3D printer print procedure, printing bottom plate 5 is gradually moved up, and 22 side of card slot of movable floor 2 is with beating
21 sides around the shaft that move up of print bottom plate 5 rotate inclination at an angle, and 13 stress of return spring starts to compress, resin frame 3
Rotated together with movable floor 2, print bottom plate 5 and 6 adhesion face unilateral side of institute's printed product at this time under the inclination of movable floor 2 with
Small range generates separation；
6) when the product 6 to be printed printing finishes, the elastic force of return spring 13 reaches the estimated limit, prints bottom plate 5
It stops operating, printing bottom plate 5 is just generated with one side that product 6 is adhered to be separated, and complete printed product is obtained.
In above-mentioned setting, the design line footpath of return spring 13 must be controlled between 0.4-0.7mm, make return spring 13
It is arranged that force variation range is necessarily less than printing bottom plate 5 and resin is adhered power, otherwise suffered Hui Li is greater than tree in print procedure
Rouge will lead to semi-finished product and fall off from printing bottom plate 5 to the adhesion dynamics of printing bottom plate 5.
