Description
Technical field
This utility model relates to increasing material and manufactures field, especially the 3D printing of " Layered manufacturing, successively superposition " formation workpiece
Machine.
Background technology
3D printing technique be Modern CAD/CAM technology, laser technology, Numeric Control Technology, elaborate servo actuation techniques and
Integrated on the basis of new material technology grow up.Due to the difference of moulding material used, the Forming Theory of 3D printer, with
And version also has nothing in common with each other, the 3D printer of successively paving powder molding is one of the most ripe structure, including metal
Powder, non-metal powder printer, its basic operating procedure has three steps, as it is shown in figure 9, the first step: powder feeding；Powder feeder unit is by stand-by powder
Deliver to spread before powder scraper.Second step: paving powder；Paving powder scraper moves horizontally, and is paved by stand-by powder.3rd step: sintering or solid
Change；Sintering equipment or solidification equipment work, by practicality powder sintering or solidification.These simple three steps are long-time repetition works
The process made, during the repeated work that this is very long, a step the most once goes wrong, and the part printed will be reported
Useless, so, people take into full account each step reliability of operation planing machine when；But, unpredictable element causes
Paving powder defect, the part rejection problem caused also is the most serious.
Summary of the invention
In order to solve to spread the part rejection problem that powder defect causes, this utility model provides a kind of band paving powder supervising device
3D printer, this printer is provided with paving powder supervising device, is entered the paving powder form before each layer of sintering or solidification by this device
Row checks, and to checking that result or paving powder defect are disposed or report to the police.
This utility model adopts the technical scheme that: powder feeder unit, piston, moulding cylinder, receipts powder cylinder, paving powder doctor blade device,
Photographic head, sintering or solidification equipment and control system etc. constitute the 3D printer successively spreading powder molding；The piston of printer exists
The intracavity of moulding cylinder, piston the most precisely can move along moulding cylinder；Paving powder doctor blade device is above piston, it is possible to lead along it
Rail left and right horizontal moves back and forth；Powder feeder unit side above moulding cylinder, has on time, according to quantity for the function of powder；Sintering or
Solidification equipment is placed in the top of piston, in order to complete sintering or to solidify the practical powder that each layer is completed；The feature of this printer
It is: be arranged over photographic head at moulding cylinder that its camera lens is directly to sintering or solidification face, and photographic head passes through wire and control system
It is connected, photographic head paving powder face form after shooting or scan paving powder.
The beneficial effects of the utility model are, the paving powder form before each layer of sintering or solidification is checked by photographic head,
And the paving picture in powder face or scan-image information are passed to control system, control system the picture transmitted or image information with
It is stored in advance in intrasystem picture or image information is compared, and it is the most effective to judge to spread powder, if paving powder is effective, control
System then instructs sintering or solidification equipment normally works, and completes sintering or solidification；If paving powder lost efficacy, control system then instructs paving
Powder doctor blade device, powder feeder unit etc. repeat once paving powder process, and the paving powder form before sintering or solidification is entered by photographic head again
Row checks, until paving powder effectively or sends warning, makes whole paving powder process constitute closed loop control, makes the yield rate of printing part
It is greatly improved.

Detailed description of the invention
As shown in Fig. 1～Fig. 8, powder feeder unit (3), piston (5), moulding cylinder (6), receipts powder cylinder (8), paving powder doctor blade device
(10), photographic head (11), sintering or solidification equipment (12) and control system etc. constitute the 3D printer successively spreading powder molding；
The piston (5) of the printer intracavity in moulding cylinder (6), piston (5) the most precisely can move along moulding cylinder (6)；Paving powder scraper
Device (10) is in the top of piston (5), it is possible to move back and forth along its guide rail left and right horizontal；Powder feeder unit (3) is on moulding cylinder (6)
The side of side, has on time, according to quantity for the function of powder；Sintering or solidification equipment (12) are placed in the top of piston (5), in order to complete
Become sintering or solidify the practical powder that each layer is completed；It is characterized in being arranged over photographic head (11), its mirror at moulding cylinder (6)
Head is directly to sintering or solidification face, and photographic head (11) is connected with control system by wire, photographic head (11) be used for shooting or
Paving powder face form after scanning paving powder.
As shown in Fig. 1～Fig. 9, the basic process of 3D printer manufactured parts is: paving powder-sintering or solidify, repave powder-
Re-sinter or resolidification, the process of the circulation that in layer works long hours；Cycle of operation starts each time, spreads powder doctor blade device
