Feature-based 3D Camera and Autonomous Software
Saccade-MD from Saccade Vision targets to solve these complexities by fully flexible MEMS-based scanning laser. This approach enables selective sub-pixel resolution in 3D. Moreover, use of MEMS-based scanning enables precise scanning of non-moving parts, so imaging quality is not affected by vibrations and motion imprecision. Flexible software allows regional scanning optimization to get best scanning results based on the digital model analysis of the scanned part. Few examples below demonstrate the importance of regional scanning optimization for easy and robust 3D inspection solution:
Example 1: Scanning of different regions with different resolution. This 3D-printed part has tiny walls (0.3mm) and to achieve the best quality, these walls were scanned in optimal direction and with optimal parameters. This way sub-pixel resolution in 3D of <20µm at 150mm field-of-view was obtained.
Example 2: In shiny parts illuminating the whole part (as typically done by 3D sensors) may generate reflections that eventually will distort the 3D image or create ‘dropouts’ on point clouds (see Image 2a). Selective imaging of Saccade-MD allows scanning in variable direction and with variable density / laser intensity (see Image 2b-2d). This local optimization avoids unnecessary reflections, improves solution robustness, and simplifies overall solution.
Example 3: For typical 3D laser triangulators, scanning direction is fixed – it depends on the direction of conveyor movement. In some cases, this can cause visibility problems that are not easy to solve. Saccade-MD can solve such visibility problems by flexible setting of scanning direction in software.
Integrated 3D Inspectionon Metalworking Machines
Modern metalworking processes, though diverse and specialized, can be categorized into one of three broad areas known as forming, cutting, or joining processes. Each of these categories contains various processes.
Saccade Vision recently partnered with Euclid Labs to deliver fast, precise and flexible optical 3D inspection solution for various types of metalworking machines. Euclid Labs provides flexible and effective software tools to face difficulties related to small batch production, high quality requirements, complex task automation for industrial manufacturing companies. Euclid partners with robot manufacturers, machine builders, sensor manufacturers and system integrators to create the best applications for automatic programming and to increase profitability of automation by reducing programming time and adding adaptive skills.
Using Euclid’s offline programming software, Saccade Vision provides fast and flexible inspection of 100% of metal parts right after the processing cycle. Parts are being handled by the same robot that is used to load and unload parts into and out of the metalworking machine. The inspection results can be used not just for quality control, but also for fast correction of the manufacturing process via smart control software.
