Digitalization in the field of surface inspection – a necessity rather than an end in itself
In many industrial sectors – such as automotive industry and their suppliers – manual vision checks of function surfaces on metal components (e.g. sealing or running surfaces on engine and gearbox casings) are still the rule. These circumstances are in many aspects critical – not only since increasingly demanding inspection requirements are naturally limited by human capabilities, but also because manual vision checks are anyway characterized by a lack of both reproducability and documentability. The strive for digital factories and their clear-cut advantages for the integrated assurance of product quality simply cannot be achieved without automated vision checks. Beyond the monotonous, tiring and often ergonomically critical work which corresponds to high levels of non-productive costs, the overall subject therefore reaches today much further than the „ratio“ aspect which formerly used to be the focus of interest when moving towards automation.
For a successful change
Very often, however, the change towards automatic vision checks is accompanied by unexpected difficulties for the users. Particularly the frequently high levels of pseudo-rejects – components incorrectly flagged as defective – are a major concern. Using a specially adapted technique which can reliably differentiate between textural features such as detergent residues or similar marks and genuine topographical surface defects such as pores, cavities or scratches, such troubles can be avoided.
Individual, fully automated solutions from a single source
Our customers, especially in automotive industry, appreciate since decades our expertise in planning, projection and realization of fully integrated complete solutions. In the field of automated visual inspections we can therefore also offer individual engineering and a variety of automation concepts tailored to the needs of our customers: be it on the basis of conventionally automated solutions, such as using NC-axes for positioning the image acquisition systems relative to the specimen or vice versa, the specimen relative to the image acquisition or be it by applying robotics for this purpose, or even safe solutions for human-robot collaborations (HRC). Each concept has its individual strengths and every customer has specific requirements: we bring both in line – to the full satisfaction of our customers around the world.
