The star rotates about the star axis with its 6 segments. The segments hold the sleeves.
There is a nozzle seated on every sleeve, which sucks up the components, and transports
them from the pickup/placement position (1) to the reject position (2), to the optical centering
position (4) or to the turning position (5).
The Z axis performs a vertical movement. Every sleeve that is in the bottom star position (1)
is raised or lowered by this axis, thus picking up the components from the feeder modules
and setting them down on the PCB. The Z axis is an "intelligent axis". It "notes" the pickup
height of each feeder module track and the placement height for each component. This can
speed up the placement process. The programmed placement force remains constant.
The DP axis rotates the optically centered component to the desired placement angle. The
sequences of movements of the rotation and translation axes are controlled by control cir-
cuits. Position and speed sensors send the actual values for the axis movement to the axis
control. The nominal and actual values are compared and used to determine the force and
speed parameters for the servo amplifier, and thus the axis movement to be performed. The
vacuum values at the nozzle are constantly checked throughout the entire pickup and place-
ment process in order to keep the placement error rate as low as possible.
