5.6 Station 6
At station 6, fine theta axis adjustment is done. Using the vision
processing data from station 4, station 6 rotates the part to its final placing
angle.
The fine theta axis adjustment combines vertical and rotational
movement.
The fine theta axis adjustment operation is driven by the rotation of a
motor and a cam mechanism. The cam drives a lever, which drives a rod,
which drives a rod, which drives the clutch.

Servomotor origin position adjustment is unnecessary. However, the
clutch vertical position and the amount of gear backlash must be adjusted.
Clutch Vertical Adjustment Procedure
(1) With the cam at 0° touch the dial gauge to the fluorescent disk and set
the gauge to zero.
(2) Using the cam handle, turn the cam handle backwards to 260°.
(3) With the cam angle at 260°, adjust the adjustment rod so the nozzle
pushes the dial gauge down to 0.25 to 0.35 mm.
(4) Repeat these procedures for other nozzles to confirm that the gap is
between 0.25 to 0.35 mm.
