Pick the component by driving
Z-axis, and adjust the
component at laser align height.
Rotate in (+) direction along
θ-axis, and start measurement
with laser align.
Placement is performed by
correcting position offset (dX,
dY) and angle offset (dθ).
While measuring the shade, find two
positions and where the shade
is minimum.
Because the nozzle center is a known
factor, according to the difference
between the nozzle center and the
component center, offset in Y direction
(dX) and that in X direction (dY) can
also be known. By referring to the
encoder output of the θ motor at or
, offset angle dθ can also be known.
