Title (EN) INSPECTION METHOD AND INSPECTION DEVICE FOR INSPECTING A SURFACE LAYER
(FR) PROCÉDÉ DE TEST ET DISPOSITIF DE TEST POUR TESTER UNE COUCHE DE SURFACE
(DE) PRÜFVERFAHREN UND PRÜFEINRICHTUNG ZUM PRÜFEN EINER OBERFLÄCHENSCHICHT
Abstract:
(EN) The invention relates to an inspection method and an inspection device for inspecting a surface layer composed of a coating medium, in particular composed of a solvent-containing pretreatment medium, a primer, an adhesive, a sealant or an insulating material, on a component (1), in particular on a motor vehicle body component (1), wherein the surface layer, after being applied to the component (1), causes a change in temperature, in particular as a result of evaporation of solvent from the surface layer. The invention provides for the temperature change caused by the surface layer to be measured, in particular by means of a thermographic camera (10), in order to inspect the surface layer.
(FR) L'invention concerne un procédé de test et un dispositif de test permettant de tester une couche de surface constituée d'un agent de revêtement, en particulier un agent de prétraitement contenant un solvant, d'un apprêt, d'un adhésif, d'un agent d'étanchéité ou d'un matériau isolant, sur un composant (1), en particulier sur un composant de carrosserie de véhicule automobile (1). La couche de surface génère, après son application sur le composant (1), une variation de température, notamment par évaporation du solvant de la couche de surface. Selon l'invention, la variation de température générée par la couche de surface est mesurée, notamment à l'aide d'une caméra thermographique (10), afin de tester la couche de surface.
(DE) Die Erfindung betrifft ein Prüfverfahren und eine Prüfeinrichtung zum Prüfen einer Oberflächenschicht aus einem Beschichtungsmittel, insbesondere aus einem lösungsmittelhaltigen Vorbehandlungsmittel, einem Primer, einem Klebstoff, einem Dichtstoff oder einem Dämmstoff, auf einem Bauteil (1), insbesondere auf einem Kraftfahrzeugkarosseriebauteil (1), wobei die Oberflächenschicht nach ihrem Auftrag auf das Bauteil (1) eine Temperaturänderung verursacht, insbesondere durch Abdunsten von Lösungsmittel aus der Oberflächenschicht. Die Erfindung sieht vor, dass die durch die Oberflächenschicht verursachte Temperaturänderung gemessen wird, insbesondere mittels einer Thermografiekamera (10), um die Oberflächenschicht zu prüfen.
