METHODS AND SYSTEMS FOR INSPECTING BEADS OF A SEALANT MATERIAL IN JOINING AREAS OF STRUCTURAL ELEMENTS

摘要

A method for inspecting a bead (11) of a bi-component sealant material in joining areas of structural elements comprising the following steps: a) projecting continuously on the application area of the bead (11) a laser light curtain (33) of a width greater than the bead width; b) taking sequentially digital images (41) of the application area of the bead (11) in a direction angularly offset with respect to the projecting direction of the laser light curtain (33); c) processing the information provided by the intersecting lines (43) of the laser light curtain (33) with the application area of the bead (11) contained in said digital images (41) to detect defects of the bead (11) and/or to obtain digital representations of the bead (11) to allow a posteriori analysis of it. The invention also refers to a system for inspecting said bead (11).
