7.1.1 Steps when picking up and placing components
– A PCB moves into the placement area of the PCB conveyor.
– The right-hand collect&place head picks up components from the feeder modules.
– The left-hand collect&place head waits for the fiducial measurement.
– Once the fiducial measurement is complete, the right-hand collect&place head places compo-
nents while the left-hand collect&place head picks up further components.
– The right-hand collect&place head picks up components, and so on.
7.1.1.1 Position and function of the individual star stations (see Fig. 7.1 - 2)
Star station 1 7
Pick-up cycle 7
The nozzle is lowered onto the component. Once the valve positioning unit has opened the vac-
uum circuit to the nozzle, the nozzle draws up the component and removes it from the feeder mod-
ule. 7
Placement cycle 7
The valve positioning unit closes the vacuum channel to the nozzle. The nozzle, together with the
component, is lowered onto the PCB that has been moved into place. A short burst of compressed
air detaches the component from the nozzle and places it on the PCB. 7
Star station 3 7
The valve positioning unit closes the vacuum channel to the nozzle. Defective components are
detached from the nozzle with a short burst of compressed air and are discarded. 7
Star station 7 7
The component is optically centered. 7
Star station 9 7
Pick-up cycle 7
The nozzle is rotated to the pick-up position. 7
Placement cycle 7
The placement angle of the component is corrected or the correct placement angle of the compo-
nent is set. 7
