CobraMotion

The growing demand for thin and flat panel displays has led FPD manufacturers to push for increased production yields. As a result, glass substrates have become larger – in order to improve efficiency, and thinner – in order to meet market requirements.
As glass substrates become larger and thinner, new and innovative non-contact handling and conveying techniques are needed to protect them from damage. The primary challenge is to ensure that the leading and trailing edges of the substrate, which naturally tend to bend toward the handling platform, will not contact the platform – thus avoiding scratches and breakage.
CobraMotion is a unique pressure/vacuum (PV) technology designed to avoid contact between a PV stage and the warped glass substrate. With CobraMotion, the vacuum force and mass flow rate (MFR) applied to the leading edge and the trailing edge of the glass are reduced, while the vacuum force and MFR applied to the center of the glass remain constant. As a result, the equilibrium height of the glass is higher at the edges than in the center, thus preventing damage to the edges of the substrate, and improving yields.
