Title
Vorrichtung zum beruehrungslosen Detektieren von Pruefkoerpern
Other Title
Device for non-contact detection of structure or surface flaw in planar body; has cooling unit and thermograph camera to detect thermal patterns appearing on body as it cools down.
Abstract
Die Erfindung betrifft ein Verfahren zum beruehrungslosen Detektieren von Struktur- und/oder Oberflaechenfehlern grossflaechiger Pruefkoerper. Zur schnellen beruehrungslosen und zerstoerungsfreien Detektierung wird erfindungsgemaess vorgeschlagen, die Prozesswaerme des Pruefkoerpers auszunutzen und das sich beim Abkuehlen des Pruefkoerpers auf seiner Oberflaeche einstellende Waermebildmuster mit einer Thermografiekamera zu detektieren.

WO 200135086 A UPAB: 20010704 NOVELTY - The device has a cooling unit (4) between the surface to be detected and a thermograph camera (5). The thermograph camera is arranged in the conveying direction (F) and spaced behind the production line (3), which detects thermal patterns appearing on the body as it cools down. A drive is provided for relative adjustment between the test body and the camera or the cooling unit. DETAILED DESCRIPTION - The thermograph camera has at least one camera line and is connected to a computer (5) with a monitor (7), which constructs a complete thermal pattern form the camera lines. USE - To detect structure of surface flaws in large-area, headed planar body. ADVANTAGE - Rapid non-contact detection. Test bodies with lower thermal conductivity, e.g. wood or wood materials, can be tested.
