8.7.2 Picking Up Components

Before the star rotates into the pickup position, the relevant valve is switched on via the valve terminal.

Vacuum from the holding circuit is now present at the nozzle.

Once the star has reached the pickup position, the holding circuit vacuum is strengthened via the

pressure control valve and the component can be picked up.

8.7.3 Placing Components

 After the component has been picked up, the

component is held on the nozzle with the help

of the vacuum from the holding circuit.

 If the star is in the placement position and the

Z down sensor is enabled, the pressure

control valve will switch over to air bast. This

eliminates the holding circuit vacuum and an

air blast of approx. 200 mbar is present at the

nozzle.

 The switch on time for max. vacuum/air blast

depends on the settings programmed in the

programming system.

 Once the Z axis has reached the top position,

the star continues to turn. The relevant valve is

now closed on the valve terminal. This saves

compressed air!
