5.3 Twin Head
5.3.1 Overview
5.3.1.1 Overview
The Twin Head consists of two identical modules which work according to the Pick & Place
principle. The second P&P segment is rotated 180 degrees.
A – Modul 1
B – Modul 2 (rotated 180° compared to module 1)
1. Main board on module 1 and module 2
2. Linear motor / ZAxis
3. D Axis
4. Incremental measurement system /
ZAxis

5.3.1.3 Main Parts / Unit Overview
Twin Head – Pressure Regulator Valve (PRV)
1. Compressed air connection
2. Output vacuum is passed through the D
Axis motor shaft and on to the nozzle
3. Discharged air for cooling the X linear
motor
The PRV automatically controls the vacuum, air blast and the zero balancing position (middle
position-→ no vacuum and no air blast) for the segments.
Twin Head – Filter
1. Filter for the vacuum system.
The Filter is mounted on the return unit and
used as an attenuator to control the vacuum.
The filter with the additional volume reduces the oscillation of the vacuum generator and
guarantees an accurate vacuum and air blast supply.
The filter is serviced at regular intervals, which must be adhered to (see maintenance Job Card).
