Abstract

Le procédé de contrôle par ressuage permet d'éviter l'intervention manuelle d'un ou plusieurs opérateurs pour les opérations préalables d'aspersion et de chauffage pour chauffer les plaques (1), les imprégner, de deux côtés du liquide fluorescent. Dans un deuxième tunnel, on procède au rinçage et au séchage des plaques (1). Le contrôle se fait dans un caisson (10) que traversent les plaques (1). Deux caméras (12) sont placées de part et d'autres du passage des plaques (1) et sont pointées au même endroit pour un contrôle simultané de la plaque (1) des deux côtés au même endroit. Une visualisation sur écran permet à un opérateur de contrôler au moyen d'une image de reconstitution d'une partie des plaques (1). Application au contrôle des plaques (1) d'échangeurs de chaleur dans le domaine de l'agroalimentaire.The penetrant inspection process makes it possible to avoid the manual intervention of one or more operators for the preliminary spraying and heating operations to heat the plates (1), to impregnate them, on two sides with the fluorescent liquid. In a second tunnel, the plates (1) are rinsed and dried. The control is carried out in a box (10) through which the plates (1) pass. Two cameras (12) are placed on either side of the passage of the plates (1) and are pointed at the same place for simultaneous control of the plate (1) on both sides at the same place. A visualization on screen allows an operator to control by means of an image of reconstruction of a part of the plates (1). Application to the control of heat exchanger plates (1) in the food industry.
