5.1 Nozzle changer for the 12-segment collect&place
head
5.1.1 Overview
The placement system is supplied as standard with four collect&place heads and four nozzle
changers. As an option, a second nozzle changer can be installed for each collect&place head.
The nozzle changer consists of at least one, and up to five magazines, each with 12 nozzle ga-
rages (see Fig. 5.1 - 1
). The magazines are seated on a common support and each magazine is
centered using two parallel pins and fixed in place with clips.

5.1.3 Mode of operation
The nozzles are seated in nozzle garages and are held in place by a movable locking plate. The
locking plate can be moved 6 mm by a pneumatic cylinder. All the nozzles are either clamped or
released, depending on the position of the plate. The default position of the locking plate, i.e. if
there is no nozzle change in progress, is "closed".
There is a positioning fiducial for position detection on each magazine of the nozzle changer. The
magazine locations are identified by numbers 1 to 5 on the nozzle changer. The nozzle garages
in the magazines are numbered consecutively from 1 to 12 (see Fig. 5.1 - 2
).
PLEASE NOTE 5
Special magazines are available upon request (contact Siemens A&D for details) and will be
numbered differently.
Picking up a nozzle 5
– The Z-axis of the collect&place head moves down.
– The locking plate (item 2 in Fig. 5.1 - 2
) opens and releases the nozzle garages.
– The nozzle is picked up by the sleeve of the collect&place head.
– The Z-axis moves up.
Setting down a nozzle 5
– The locking plate (item 2 in Fig. 5.1 - 2) opens and releases the nozzle garages.
– The Z-axis of the collect&place head moves down and sets the nozzle down.
– The locking plate closes.
– The Z-axis of the collect&place head moves up.
Discarding defective nozzles 5
– The Z-axis of the collect&place head moves down 14 mm towards the discarding device
(item 2 in Fig. 5.1 - 1
) and thus moves the defective nozzle into the hole in the discarding de-
vice.
– The Z-axis moves up again and the nozzle is stripped from the sleeve by spring wires.
– The nozzle drops into the container of the used tape guide channel (item 6 in Fig. 5.1 - 1
).
