6.1 Workpiece Alignment
Alignment uses the Vision System to precisely align a Workpiece parallel
to the Blade to ensure accurate cutting down the middle of each Street. The
User has the option of choosing either Auto Alignment (performed
automatically by the Pattern Recognition System - PRS) or Manual
Alignment (performed by the User). In order to perform Auto Alignment,
the System must first be taught Alignment. Once Alignment has been
taught for a Recipe, the System automatically align all the Workpieces that
have been assigned the same Recipe.
The idea of alignment is based on having the System remember two points
on the workpiece. These two points define the baseline for adjusting the
parallelism of the kerfs. Once the Workpiece has been aligned, the
alignment is taught to the System. Afterwards, the System automatically
updates (straightens) the substrate position on the Cutting Chuck by
turning the Theta Axis.
