An online monitoring device for metal 3D laser printing

Abstract

The invention discloses an online monitoring device for metal 3D laser printing, comprising a support, a column on the support, two cantilever rods slidably arranged on the column, and the two cantilever rods can be rotated around the column independently. There is an adjustment seat slid on the rod, and the adjustment seat can be rotated around the cantilever rod. The adjustment seat is rotated with a track plate, and the track plate is slid with a mounting seat, and a camera assembly is fixed on the mounting seat; it can automatically grab the 3D laser When printing images, the dual-camera hardware device can realize multi-angle detection and position adaptive adjustment, without space constraints, the camera adjustment accuracy is high, and adaptive image overlap can be achieved, with high efficiency and reliability.

Description

technical field [0001] The invention belongs to the technical field of metal 3D laser printing, in particular to an online monitoring device for metal 3D laser printing. Background technique [0002] In the field of metal 3D laser printing monitoring, quality assurance and process monitoring have always been the hot research directions of metal 3D printing technology, and effective and reliable quality assurance methods are the biggest needs of users. [0003] At present, the monitoring of the printing process still mostly stays on the monitoring of the equipment status, the data collection and analysis of the material forming is insufficient, the feedback mechanism is even less satisfactory, and the data analysis ability is also lacking in the face of a large amount of data, resulting in the existence of processed parts. Various quality defects and low survival rate greatly affect production efficiency. [0004] The shortcomings of the existing monitoring equipment: 1. The...

Problems solved by technology

[0003] At present, the monitoring of the printing process is still mostly on the monitoring of the equipment status, the data collection and analysis of the material forming is not sufficient, the feedback mechanism is even more unsatisfactory, and the data analysis ability is lacking in the face of a large amount of data, resulting in the existence of processed parts. Various quality defects and low survival rate greatly affect production efficiency

[0004] The shortcomings of the existing monitoring equipment: 1. The monitoring equipment mainly controls the 3D printing equipment itself, and does not effectively improve the quality of the printed parts; 2. There is no analysis of the collected images, no feedback mechanism, and lack of closed-loop feedback capabilities; 3. The quality of the printed parts is uneven, and there are various quality defects; 4. The production efficiency is low, and the products cannot be mass-produced quickly
