3.2.2 Pneumatic Unit
3-10: Pneumatic unit as rack unit
Legend
The pneumatic unit is mounted on a compact rack unit and is located on the right in the middle section
of the machine. Unauthorized access to the unit is prevented by a locked door, which can be opened
with a machine key. The pneumatic unit includes all electrical connections for control/regulation of the
compressed air supply and the conveyor control. The conveyor control with the SMEMA (Siemens)
board interface is responsible for the transport of boards in the machine and for the transport from the
upstream and downstream station.

3.2.2.1 Pneumatic Circuit For Cooling the Y Linear Motors in Placement Areas 1/2
An additional pneumatic circuit, supplied with ambient air, has been integrated to cool the Y linear
motors. The ambient air is sucked in via a filter, with the help of a fan motor and is distributed to the Y
motors. The compressed air then escapes through the sides of the Y motors.
3.2.2.2 Pneumatic Circuit For Cooling the X Linear Motors in Placement Areas 1/2
The X motors are cooled by the discharged air from the vacuum generator of the C&P20A head.
3.2.2.3 Compressed Air Distributor Block
The pneumatic unit is used to prepare and distribute the compressed air required in the machine. The
inlet pressure at the compressed air connection must be at least 5.0 bar.
The following pneumatic circuits are supplied with compressed air via the distributor block:
Gantries 1 - 4 (placement heads), vacuum generation: 5.0 bar
Conveyor system: 5.0 bar
Tape cutter for locations 1 - 4: 5.0 bar
Nozzle changer for locations 1 - 4: 5.0 bar
Feed-in units for the changeover tables: 5.0 bar
Bulkcase feeder for locations 1 - 4: 2.5 bar
Fine adjustment for the individual pneumatic circuits is performed directly at the pneumatic units, via the
adjustment valves.
