The object of quality check is to determine if a product has a
quality compliant with the standards in force and with the quality requirements of the end customer.
In addition to this, the quality system serves to intervene on the production processes in order to identify the causes of non-compliance and take the initiatives to correct them. An IT system linked to quality must therefore be able to supply data relating to the entire production process a posteriori
In the flat glass sector, the automatic optical control of the shape / defects of the products. The computer system must be able to analyze the entire image and classify the defects of Size, Shape, Intensity. The complexity of this operation is due to the fact that the detection and analysis phases must be timely enough not to negatively affect the productivity of the company. To meet this need, i computer controls who "decide" or help the operators.
The solution adopted today in the glass sector is the "scanning" of a panel of
glass just before the last stage of processing, called assembly and immediately after the stage of
wash.
Scanning is done through a real scanner (hardware) that it acquires
the image of glass. This image is analyzed by a and subjected to certain controls, in order to be classified as "compliant" or "non-compliant".
