The optical inspection of adhesive beads in-process has many advantages. It is fast and requires no additional process time. No additional inspection positions have to be approached with the robot – the inspection takes place directly during application. This is often realised with a sensor head in the direct nearness of the nozzle (e.g. with the product Cyclospotter).<\/p>\n\n\n\n

Where, however, accessibility to the application nozzle must be maintained or hot processing or nozzle temperatures prevent this, as in hot melt or hot butyl applications, VisionTools offers a solution of an in-process inspection with stationary cameras. With this method, cameras (usually three) and illuminations are arranged at a greater distance from the application nozzle.<\/p>\n\n\n\n

When there is only a small contrast between the application compound and the background, such as in hotmelt applications, or when the temperature of the substrate or workpiece is a quality criterion, thermal imaging cameras can also be used. A combination of thermal imaging camera and colour camera enables additional inspections and a position check based on distinctive geometries on the workpiece.<\/p>\n\n\n\n

The position, width and interruptions are checked. Only one inspection software is used for all our adhesive bead in-process inspection systems. In practice, application speeds of 500 mm\/s are achieved.<\/p>\n\n\n\n
