10.2.1 Twin Head Placement Principle
Twin Head Placement Principle
During the PCB transport time, the gantry waits at the theoretical fiducial position, to perform board cen-
tering (and inkspot recognition) after PCB clamping. With the " Whispering down the machine" option,
gantry 3 only evaluates 2 fiducials.
Than the Twin-head start to collect one component with module 1 and one component with module 2.
These components are then centered with the IC camera (FC camera) and are placed.

Filter for the vacuum system (example of Twin segment
version 03 shown)
Legend
1. Filter for the vacuum system on the Twin- head.
The Filter is mounted on the retract unit and used as an
attenuator to control the vacuum. The filter with the addi-
tional volume reduces the oscillation of the vacuum gen-
erator and guarantees an accurate vacuum and air blast
supply. The filter is serviced at regular intervals, which
must be adhered to (see maintenance guide).

▪ PCB position recognition and ink spot recognition is
performed.
▪ The X and Y gantry axes move to the feeder track or
pickup position.
▪ During gantry positioning, the D-axis rotates to the
pickup angle.
▪ Communication with component trolley - feeder
ready - opens the feeder pickup window.
NOTICE
To achieve greater placement accuracy, the offset between the nozzle and the IC camera is
checked after a defined period, with the help of a fiducial. The fiducial is on a metal plate, which
is fixed between the stationary camera and the machine frame.

3. Force sensor
▪ Z-axis moves downwards with standard mode (2 N
pickup force).
▪ On contact with the component, the force increases
to the programmed value.
▪ When this value is reached, the end signal is trig-
gered and the vacuum check is activated.

▪ The Z-axis moves upwards with standard travel

▪ Kommunikation mit BE-Wagen Förderer weitertakten
sobald die Z-Achs- Position "Sicherheitshöhe"
(25 mm für D3, 17 mm für D1/D1i für die BE-Unter-
seite) erreicht ist.
▪ When the Z-axis up end signal is emitted, the "com-
ponent on nozzle" vacuum check is performed.
▪ The D-axis is rotated to the placement angle (so that
only the component correction angle needs to be ro-
tated after centering).
▪ Preparation for continued pickup (component on
module 2).
