New 3D Area Profile Scanner Extends Robot Guidance Applications

New Area Profile Scanner 3D (APS3D) from Isra offers flexibility, accuracy and versatility. The smart, highly-accurate sensor innovation allows exploitation of new 3D robot guidance and automation applications.

Combined with 3D robot guidance and 3D inline measurement technology, the Isra APS3D sensor is ideal for performing complete inspection checks and quality control on automated production lines. Tailored software packages ensure the sensor provides reliable results in all applications with short cycle times.

Inspecting a surface for bumps and indentations, measuring a hole diameter or capturing a free-form surface for CAD data matching are all measuring tasks that can arise during the inspection of deep-drawn metal or injection-molded parts. With its combination of stereometry, triangulation and phase-shift structured lighting, the newest generation of 3D Area Profile Scanner can be used wherever object geometries need to be measured accurately at high speed.

The sensors stereometric two-camera system uses triangulation to calculate the surface of an object with the highest precision in three dimensions. The sensor uses random pattern or phase-shift lighting. Random pattern lighting delivers the sensor the necessary points of reference in a single image, significantly speeding up scanning times and shortening cycle times. Object detection and part inspection can also be achieved “on the fly” with moving objects and without motion blur further resulting in minimum cycle times.

APS3D is available in different model variants with measuring fields up to 460 mm x 360 mm. Collected point cloud data can be exported for CAD data matching. The sensor’s integrated PC can also directly export in STL format digitally mapping complex surfaces. The sensor can be deployed as a stand-alone solution, integrated into the production line or mounted on a robot, and is compatible with all conventional Ethernet and fieldbus interfaces.

Based on geometric relations, the APS3D checks the quality of surfaces, the correct size of boreholes and the correct spatial relationships between object features within one scan. The Windows operating system, the intuitive user interface and menu guidance, and the multi-touch navigation are easy to use.

Maximum flexibility is provided by “Touch & Automate” application-specific software modules, including 3D robot guidance and 3D in-line measurements, mean that the sensor is highly adaptable and flexible. The Plug & Automate concept allows for quick commissioning. As part of the “Touch & Automate” automation concept, the APS3D is equipped with Wi-Fi capability to communicate with other sensors and with a shared database. The systems used within this sensor network are able to communicate to fulfill larger measurement tasks with the aggregated data used directly for process analysis. Using a higher-level quality and yield management software, operators can directly access the collected data for use in reports and analysis.

Its flexibility, connectivity and adaptability make the 3D sensor an ideal component for enabling networked industrial production and Industry 4.0 integration.
