A kind of laser fast forming paving powder uniformity detecting system and detection method
Technical field
The present invention relates to a kind of laser fast forming paving powder uniformity detecting system and detection method, belong to laser the most rapid-result Shape paving powder detection technique field.
Background technology
3D prints (increase material manufacture) technology, is an emerging technology developing rapidly of manufacture field, is referred to as " tool There is the manufacturing technology of industrial revolution meaning ".It is a kind of based on the discrete and manufacturing technology of accumulation principle, and it is by the three-dimensional of part It is discrete that certain way pressed by computer-aided design (CAD) model, becomes machinable discrete, discrete lines and discrete point, then Use physically or chemically means, these discrete faces, line segment and point are piled into part shape.3D printing technique is by being superimposed as The three-dimensional CAD model of design can be converted into the part with certain 26S Proteasome Structure and Function by shape method.With traditional manufacturing technology phase Ratio, " 3D printing " technology possesses following Core Superiority: 1. operation is simple, and the manufacturing cycle is fast.2. it is skillful in somewhat complex design, pushes away Dynamic design innovation, it is achieved by " manufacture and determine design " to the transformation of " design driven manufacture ".3. realize flexible, efficient, economical Small lot manufactures.3D printing technique be mainly used in Aero-Space, weapons, medical treatment, Making mold and artistic creation, building, The fields such as clothing, the introducing of 3D printing technique has also opened up wide space for innovation.The following development of 3D printing technique will make Large-scale personalized production is possibly realized, it will bring the major transformation of global manufacturing.
The most typical quick forming method has: selective laser sintering (SLS), selective laser melting (SLM), light are solid Change solid forming (SLA), Fused Deposition Modeling (FDM) etc..SLS with SLM forming process is similar, and during work, power spreading device will become Shape powder is taped against formation cylinder, and then laser beam is sintered into selectively according to the layering profile of part under the control of the computer Shape, after having sintered one layer, matrix moves down a cross section thickness, and power spreading device lays new powder, and computer controls laser beam and again enters Row thermal sintering, so circulates, and is layering, until obtaining complete drip molding.Paving powder is to close in SLS and SLM forming process Key link.Paving powder quality will directly affect forming efficiency and drip molding quality.If paving powder is uneven, out-of-flatness, laser sintered In forming process, inside parts will produce defect, and forming accuracy declines, and even can not shape.SLS and SLM forming process at present Middle berth powder uniformity is difficult to monitor, can only manual observation, time and effort consuming, and be difficult to real-time tracking observe.Meanwhile, each burning Knot layer drip molding overall size is difficult to measure, and printing precision cannot ensure.
Summary of the invention
For solving the technical problem that prior art exists, the invention provides one and can monitor whether paving powder puts down in real time Whole, it is effectively improved laser fast forming paving powder uniformity detecting system and the detection method of Forming Quality.
For achieving the above object, the technical solution adopted in the present invention is a kind of laser fast forming paving powder uniformity detection System, including forming cavity, is provided with power spreading device, for powder cylinder, formation cylinder and the cylinder that gathers materials in described forming cavity, it is characterised in that: The top of described forming cavity is provided with laser instrument and image collecting device, and the both sides of described forming cavity are provided with light compensating lamp, described Laser instrument, image collecting device are all connected with control system with light compensating lamp.
Preferably, the outside of described image collecting device is provided with lens protective cover.
Preferably, described image collector is set to high-resolution industrial CCD camera, and light compensating lamp is LED.
A kind of laser fast forming paving powder uniformity detecting method, follows the steps below operation,
A, control system control power spreading device and carry out spreading powder；
After b, paving powder complete, the powder completed is taken pictures by image collecting device, and image information is transferred to control system；
C, control system carry out gray proces to image information, then the gray value of image are being analyzed detection；
D, control system are according to the gray value obtained, it is judged that paving powder is the most smooth qualified；If spread, powder is defective will send finger Order, carries out secondary or repeatedly spreads powder, until paving powder is qualified；If spread, powder is qualified carries out laser sintered one-tenth by control laser instrument Shape；
After e, one slicing layer of laser sintering (SLS), the drip molding profile of this slicing layer of sintering is clapped by image collecting device According to, and image information is transferred to control system；
The drip molding profile of this sinter layer is measured by f, control system, and measure the item includes: point, line, circle, arc, distance, ellipse Circle, angle etc.；
According to the size of formed part tolerance of metrical information and setting, g, control system judge that this sinter layer size of formed part is No reach requirement, thus adjust corresponding forming technology.
Compared with prior art, the present invention has following technical effect that the present invention can monitor paving powder whether uniform ground, If paving powder is uneven, will heavily spread, until paving powder uniform ground；Monitor each sinter layer drip molding profile chi in real time Very little, thus adjusting process parameter, improve part forming precision.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
