Pickup and Placement Cycle for CPP Standard Mode - Placement: Z Axis Down

Standard Mode - Placement: Z Axis D own
8.4.13 Standard Mode - Placement: Z Axis Down
Axis controller:
▪ Enable signal for "light barrier down" function
LB down switches:
▪ End signal Z axis positioning downwards;
▪ Digital pressure control valve: switches "Air blast ON"
▪ Pickup/placement position; air blast threshold "place component" reached? Yes
NOTICE
Since the travel paths for each axis can be calculated and are therefore known, the next action
(e.g. starting the Z axis) is started via position flags. These are sent by the predecessor action
(e.g. star axis). This enables the Z axis to start moving 10 ms earlier (depending on the
definition). It no longer needs to wait for the end position signal from the star axis. The end
position signal is therefore no longer in use.
Detailed component placement procedure: Z Axis Down
In this mode (light barrier down) the placement force at
the placement head is around 2N.
End position signal for X and Y axes--> Z axis starts:
▪ Positioning of Z axis downwards
▪ Component sensor checks component. Z axis
measurement value - nozzle length "with component"
- threshold reached? Yes
End position signal for star axis:
▪ Performsing vacuum test "before placement".
"Vacuum closed" threshold reached? YES to
determine whether the component is held by holding
force on the nozzle.

Optical Nozzle Query
8.4.15 Optical Nozzle Query
▪ After the reference run, the gantries move into the wait position and performs the first nozzle
scanning. During the production, a nozzle scanning run is performed after 350 head cycles (can be
set by SIPLACE service if required) and after the completion of the board currently processed. This
ensures that the nozzle quality is continually checked during the production process:
– All nozzles listed in the scan parameters of the station database will be measured by the
component camera.
– If there is any deviation from the defined size, shape or brightness, the machine will show the
message: Nozzle worn down or contaminated.
▪ Tiny nozzles may touch the solder paste or the glue because of component shift and the minimum
component height.
▪ The number of components per segment (number of head cycles), after the next nozzle query has
been performed, should be adjusted to the customer's process requirements. This check is always
performed after completing PCB processing.
