7.3.5 Cleaning Cycle - Procedure

7-13: Vacuum check procedure

 The gantry axes move the C&P head to the

reject position so that the nozzles can be

cleaned before the measuring cycle.

 The Star axes move in an anticlockwise

direction and all cleaning functions are

performed at the same time, within one head

cycle.

1. The DP drives rotate each segment into the 0°

position.

2. The digital pressure control valve now

activates the air blast for the reject position.

The components still on the nozzle will be

rejected.

NOTE:

In SIPLACE X machines, components are rejected in the pickup/placement position.

7.3.6 Height Reference Run

With this function we check the correct fitting of the nozzle on the sleeve and that the correct nozzle type

like the programmed one are set to the sleeves. The nozzle length is taken to calculate the pick up and

placement height for the subsequent placements.

7-14: Measuring the nozzle height

Legend

 The gantry moves the placement head to the fixed conveyor side at height measurement position.

 The star turns the segment for measuring into the pickup/placement position

 The value "Vacuum open" is measured for each segment.

The Z axis is positioned downwards:

 When the component sensor beam is interrupted, the Z position of the axis is determined for the

component sensor.

 When the Z axis touches the conveyor side, the mechanical nozzle length is determined by the Z

position value and the closed vacuum value is measured.

The Z axis is positioned upwards:

 When the component sensor beam is no longer interrupted, the Z position of the axis will be

measured again for the component sensor.

1 Top edge of the fixed conveyor side 3 Last step with segment 20 to measure the

nozzle length.

2 First step with segment 1 to measure the nozzle

length.
