5.2 Pick up Cycle of the C&P-Head
5.2.1 Steps when picking up and placing components
– A PCB moves into the placement area of the PCB conveyor.
– The right-hand revolver head picks up components from the feeder modules.
– The left-hand revolver head waits for the fiducial measurement.
– Once the fiducial measurement is complete, the right-hand revolver head places components
while the left-hand revolver head picks up further components.
– The right-hand revolver head picks up components, and so on.
5.2.1.1 Position and function of the individual star stations (see Fig. 5.1 - 5)
Star station 1 5
Pick-up cycle 5
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. 5
Star station 3 5
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. 5
Star station 7 5
The component is optically centered. 5
Star station 9 5
Pick-up cycle 5
The nozzle is rotated to the pick-up position. 5
