| abstract |
The present invention relates to devices for automatically applying or generating and monitoring a structure to be applied to a substrate, preferably an adhesive bead, adhesive track, adhesive seam, sealing seam, a foam profile, continuous profile, geometric profile, in particular a cylinder-like profile or a triangular profile, or a weld which has an application device (10), an illumination device (20), at least two cameras (31 to 36) and an image evaluation unit, wherein the illumination device (20) emits one or more light paths, which are respectively applied to the substrate and the applied structure (6 ) are projected immediately after application, and wherein the one or more light paths (21) projected onto the substrate and the applied structure are processed by the cameras (31 to 36) in the online mode immediately after application of the applied structure (6). and the image evaluation unit detects such st is or will, that the image evaluation unit uses the change of the projected light path (21) or light paths by means of calculation methods to determine at least one feature of the applied structure (6). According to the invention, the illumination device has at least one and preferably at least two pairs of light sources, wherein the light sources of the light source pair, in particular of the respective light source, project light in the same plane onto the substrate. |
