ISRA Vision's Plate Glass Inspection System

At China Glass 2013, ISRA Vision, a specialist in surface inspection technology, presented a new range of products consisting of precisely synchronized inspection systems designed for the processing steps in glass plate manufacturing.

In addition, the systems facilitate process optimization and output management.  

The new, modular PowerPlate (P²) line of products is esigned to not only inspect but also optimize the quality of the manufactured products. It is designed to improve the glass production processes, from the melting furnace to the finishing processes.

The company reports that the unique P² (PowerPlate) product line ensures inspection reliability even for batches that include rectangular glass plates or those with random shapes. Each individual defective plate is detected and can be sorted out immediately.

The PowerPlate family is currently made up of nine products that are synchronized exactly to the relevant demands guaranteeing reliable quality inspection even at highest production speeds. Of particular note: the products can be combined randomly to account for the variety of different quality needs.

P²-SIZE performs a non-contact inspection of the plate's geometry after it has been cut. This includes the inspection of the plate dimensions, checking for edge defects and broken corners.

P²-INSPECT provides the capability to perform a 100% in-line inspection for surface defects at highest resolution settings. The system detects absorption defects such as bubbles and stones, but also scratches and other defects.

P²-COATING is especially designed to optimize the coating process.To improve the coating quality, any coating defects and inconsistencies are identified reliably and at an early stage. This reduces overall production costs and at the same time helps to conserve resources. The system can be used for all coating types, such as low-E, sun protection, anti-reflective, reflective and much more.

P²-COLOR reliably inspects the color of coatings and ensures a consistent optical effect of glass elements in the process, while at the same time ensuring that resources are being conserved. The module inspects vertically for coating uniformity and also inspects the color gradient between sharp and wide angles.

P²-3D measures the form and evenness of curved glass plates of any size. Inspecting the plates after they have been curved ensures that processes in the melting furnace are optimized and helps to keep the production conditions stable, which guarantees the highest possible quality and increased productivity.

P²-LAMI is responsible for guaranteeing in-line inspection of the laminate either before or after the autoclave process. While doing so, the system is able to detect absorption defects.

P²-CONTOUR ensures a guaranteed 100% in-line inspection of form of glass elements and also has the capability of measuring the dimensions.

P²-EDGE allows a comprehensive, reliable and cost-effective inspection of the edges of glass plates. Because of its clever design, the system makes it possible to capture a panoramic image of the glass edge so it has a full view of everything. This applies to flat glass, patterned glass, cut and asymmetric glass, and much more.

P²-OPTICS allows a comprehensive optical quality inspection that helps to prevent optical distortions and other optical effects. There are a variety of filters available for measuring.

All inspection data is processed and classified in real time. The characteristics of each product, the dimensions and defects for example, are stored numerically and visually. This information can be called up again at any time. A single click is all that is needed for the system to show the quality categorization for each batch.
