DashboardCheck Automation Technology

DashboardCheck AutomationTechnologyThe manufacturing of foamed plastics involves several challenges. Foaming parts comprise air cavities which, when large enough and located close to the surface, can lead to critical material unevenness. Such product deficiencies can lead to high economic loses, not only due to repair costs, but also through loss of reputation. This is particularly true in the case of prestige objects such as cars, where the dashboard is permanently in the view of the driver. For this reason, foamed components, such as dashboards, must be checked during production as precisely as possible. However, the common methods for quality assurance in production are still manual and visual inspections, highly depending on the “human factor” and causing high error rates. In contrast, the inspection using active thermography with the DashboardCheck system currently means the worldwide only reliable assessment method to assure the quality of foamed parts. This technique enables not only a fast scan of the complete part, but assures also a very precise detection of critical voids in a non-destructive way.

Measuring Principle

The inspection is based on the analysis of a short thermal imaging sequence (of approx. 5 seconds). During the cooling phase of a freshly foamed part, a special infrared camera records the heat radiation emitted at its surface. Since the trapped air inside of a void has a poorer thermal conductivity than its surrounding material, air cavities actually block the flow of heat. This is why less heat appears at the surface on top of a void. Through the thermal image analysis by the DashboardCheck software, these cold spots are clearly displayed in the processed result images. Moreover, the operator gets information about the exact location of an air cavity, its size and depth.

Easy Integration into Production

Our DashboardCheck system is consequently designed to allow an easy integration into any production line. The image on the right shows an example, where the measurements are performed automatically. Here the barcodes of the I-panels are read automatically when the parts are placed on a conveyor belt by a robot. A light barrier then starts the measuring process. The assessment of the measurement data can take place at any time later during the process. With the barcode of the part, the result image can be displayed at a different work-station to the operator, who then can classify the part as “O.K.”, “Not O.K.” or “Repair”. For accurate traceability, all measurement data are automatically stored in a database with its associated barcode. The database server has various interfaces and can be easily integrated into all networks, so that all measured data can be retrieved from any location at any time.
