Placement Procedure
"High force": Placement force depends on current of Z Axis, to determine end signal of Z Axis down
and vacuum generator switch to air blast.
Reject Procedure
"Defective" or "missing" is determined by:
●
Optical centering
●
Component sensor
Temperature Compensation
The temperature sensor is regularly checked and offset value will be calculated and will be used to
increase placement accuracy.

5.2.4 Vacuum System Overview
5.2.4.1 Vacuum System Function Overview
The vacuum system consists of two main parts:
Pickup/placement circuit: vacuum to pickup and hold the component, air kiss for placement.
Holding circuit: holding the component when component is on nozzle but not in pickup position.
Pickup Circuit (Vacuum)
1. Vacuum distributor (4.8 -5.0 bar)
2. Z Axis retract unit
3. Air for cooling system X Motor
4. Segment
5. Pickup/placement circuit
6. Holding circuit
7. Smoothed distributor disc
8. Intermediate distributor board
9. MHCU
●
During the pickup process, maximum vacuum is applied to the nozzle.
●
Measurement of vacuum/ air kiss value is performed by the pressure control valve.
Placement/Reject Circuit (Air Kiss)
●
The pickup/placement circuit is connected to the hold circuit via the smoothed distributor disc.
●
The PRV valve can be infinitely adjusted between max. Vacuum and max. air kiss in the
pickup/placement circuit.
