GLASS INSPECTION

The fixture (*) consists in an aluminium anodized light alloy frame, with a base, links coupled to the base and columns, coupled to the links for supporting the reference elements and the measuring probes.
The inspection consists in 14 distance measurements performed either on the glass surface or on its edge by means of 14 Marposs RED CROWN™ HPA50L pencil probes (HBT, range +/- 5mm, soft touch, pneumatic push).
The output signals of the pencil probes are acquired by Marposs GAGE BOX™ modular data acquisition system, elaborated and displayed by Marposs E9066T™ Industrial PC with Marposs Quick SPC™ process and quality control software and Marposs Quick SPC Glass, an Add On for Quick SPC specifically developed for the measurements of automotive glass. Quick Spc Glass includes a "best fit" algorithm that can be applied to the measured data for providing real time, reliable information about:

• good/reject glass condition
• glass shape errors
• glass symmetry errors

independently from the positioning of the glass on the fixture.

(*) The fixture EASYREF™ is designed and produced by MOD.EN srl and configured through a dedicated software developed by ITACA srl.
