11.12.3 Basic principles
The nozzles are seated in nozzle holders, and are fixed in place by a movable locking plate. The
locking plate can be moved up to 6 mm by a pneumatic cylinder. All the nozzles are either clamped
or released, depending on the position of this plate. The locking plate is always left in the “closed”
position if no nozzle exchange is taking place. 11
All the nozzle changer magazines have a position fiducial for position recognition purposes. The
magazine locations on the nozzle changer are identified by numbers 1 to 7. The nozzle holders in
the magazines are numbered consecutively from 1 to 12 (see Fig. 11.1 - 3
). 11

PLEASE NOTE 11
Special magazines are available upon request, and are given a special identification. Please con-
tact Siemens PL EA 1E to discuss. 11
Picking up a nozzle 11
– The Collect&Place head Z-axis moves down.
– The locking plate (item 3 in Fig. 11.1 - 2
) opens and releases the nozzles.
– The nozzle is picked up from the sleeve of the Collect&Place head.
– The Z-axis moves up.
Returning a nozzle 11
– The locking plate (item 3 in Fig. 11.1 - 2) opens and releases the nozzles.
– The Collect&Place head Z-axis moves down and releases the nozzle.
– The locking plate closes.
– The Collect&Place head Z-axis moves up.
Rejecting defective nozzles 11
– At the reject device (item 2 in Fig. 11.1 - 1), the Collect&Place head Z-axis moves down 14 mm,
and thus feeds the defective nozzle into the hole in the reject device.
– The Z-axis moves up again, and the nozzle is removed from the sleeve by spring wires.
– The nozzle drops into the collecting tray of the empty tape track (item 3 in Fig. 11.1 - 1
).
11.12.4 Notes on operation
Å When you fill a magazine with a certain nozzle type for the first time, mark the magazine with
an adhesive label.
PLEASE NOTE 11
Fill the magazines off the machine, and always replace complete magazines. 11
Å Open the locking plate, and insert the nozzles into the nozzle holders.
Å Close the locking plate so that the nozzles cannot drop out of the magazines.

CAUTION 11
The magazines must not be filled until all the nozzles on the Collect&Place head have been
returned to their magazines. 11
Å See the UNIX line computer user manual for instructions on programming the nozzle changer
on the line computer.
PLEASE NOTE 11
Å Be careful not to drop components onto the magazines, since they could cause the locking
plate to jam.
Å Also avoid dropping components onto free feeder locations, since the components will stick to
the magnetic bar. The work flow may be interrupted if the feeders are not placed on the com-
ponent feeder table correctly. You should therefore regularly clean the magazines and free
locations.
