Checking Profiles Continuously
Profile Inspect, a line laser light section sensor from EVT Eye Vision Technology GmbH, Karlsruhe, Germany, monitors dimensions and profile cross-sections in the production of profiles and pipes. It continuously captures the cross-sections of moving semi-finished goods, e.g. extruded profiles or other viscous materials. Integrated image processing software measures the geometry of the product while the instruction set ensures that all relevant dimensions, such as angles and radii, are shown and the tolerances monitored.
The sensor housing, which measures 140 ¥ 70 ¥ 35 mm, contains a 5 mW line laser in addition to a camera. Using a triangulation method, the laser takes 3-D images in real-time at a scan rate of up to 400 Hz. The 3-D images are evaluated by the smart camera’s DSP processor, which can execute 5,600 MIPS.
The user has the option of displaying all the results on as many as 16 results windows on one screen. All image and data results can be saved with additional data on any Ethernet-connected computer.
