Title:
ベッド・オブ・ネイル式形状測定におけるピンの高さ調節
Document Type and Number:
Japanese Patent JP2010510518
Kind Code:
A
Abstract:
Systems, methods, apparatus and products relate to systematic calculation and execution of pin height adjustments within a bed of nails shape measurement gauge with respect to a measured subject, such as glass substrates, and in particular, to using a bed of nails gauge for measuring a gravity-free shape of a surface of an object, including glass substrates used to make liquid crystal display (LCD) glass sheets. One or more embodiments may include a plurality of pins operable to support the surface during measurement. Each pin comprises a load cell operable to transmit measurement signals, and a height adjuster operable to receive adjustment signals and execute pin height adjustments upon receiving adjustment signals. Execution of the pin height adjustments systematically positions the pins so that the surface exerts on each pin a measured force nearing a target force corresponding to the gravity-free shape.
