State-of-the-art inspection solutions for quality yield management
Surface defects impair the quality of the manufactured metals to a high degree.They lead to waste and numerous customer claims:less throughput,higher costs,and less ability to deliver usable quality are some of the consequences.Surface inspection does not only enhance the quality of the end product,but more importantly all process steps along the production chain are optimized as well.Leading-edge surface inspection systems (SIS)deliver defect information to be turned into quality data.SIS combine detection and classification algorithms with virtually all available camera and illumination technologies for highly advanced inspection performance.This solution enables accessing the inspection results via the intemet,is based on GBit Ethemet camera technology,and deploys standard compact PCIs.For metals producers,this approach guarantees proven quality,high productivity,and efficient processes.ISRA & PARSYTEC now exploit the technology portfolios of both companies resulting in an improved inspection product-espresso SMASH serving all coating line applications:from hot dip galvanizing and electrolytic galvanizing via tinning to color painting including other organic coating lines,espresso SMASH offers the highest applicability and detection performance for coated steel due to digital line scan cameras and white LED lighting for optimized image quality.Additionally,FPGA capabilities contribute to the advanced image analysis.The software-based quality yield management platform parsytec 5i supports unlocking a huge amount of data retrieved from different databases to be transformed to quality information aiming to get a fast and reliable decision in process flow.It is an advanced software implemented method to support an inspector s decision about a coil after processing to determine the coils future,ship or block,process,repair or re-route.For the first time,the full spectrum of gauge data from surface inspection to online roughness can be exploited to generate intelligent quality decisions.Further application examples will be given in order to illustrate the possibilities of simplifying the operator s decision processes in favour of high-end production results.
