Real-time monitoring and traceability system and method for photocuring molding process

Abstract

The invention provides a real-time monitoring and backtracking system and method used for a photocuring molding process. The real-time monitoring and backtracking system comprises an image obtaining device used for obtaining laser scanning images, a parameter collection system and an image and parameter analysis system, wherein the parameter collection system comprises a plurality of collection devices used for collecting parameters needed in the photocuring molding process in real time, and each collection device correspondingly collects one parameter; the image and parameter analysis system is connected with the image obtaining device and the collecting devices, and carries out storage and analysis on the laser scanning images obtained by the image obtaining device and real-time parameter values obtained by the parameter collection system. In the part making process, problems can be found in time, part making is suspended, information backtracking in the part making process is carried out after part forming, and later-period analysis processing is carried out.

Description

technical field [0001] The invention relates to the technical field of photocuring molding, in particular to a real-time monitoring and traceability system and method used in the photocuring molding process. Background technique [0002] 3D printing (also known as additive) manufacturing technology is an advanced manufacturing technology driven by CAD digital models and using specific materials to make three-dimensional physical models layer by layer. There are many kinds of 3D printing technology, among which the top projection SLA (light-cured rapid prototyping) is a typical one. The basic process of its manufacturing is: first, design a three-dimensional solid model through CAD, use discrete programs to slice the model, design Scanning path, the data generated will precisely control the movement of the laser scanner and the lifting platform; secondly, the laser beam passes through the laser scanner controlled by the numerical control device, and irradiates the surface of ...
