5.1 Nozzle changer for the 12-segment Collect&Place
head
5.1.1 Overview
The placement system is supplied as standard with two Collect&Place heads. As an option, a noz-
zle changer can be installed for each Collect&Place head. This enables the nozzle configuration
to be changed quickly, thus allowing the Collect&Place head to be quickly adapted to the needs
of the placement process. 5
The nozzle changer consists of at least one, and up to eight magazines, each with twelve nozzle
garages (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 a spring hook. 5
NOTE:
Please refer to Section 5.9 on page 193 for information on the the nozzle changer for the 6-seg-
ment Collect&Place head. 5

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". 5
There is a positioning fiducial for position detection on each magazine of the nozzle changer. The
magazine locations are identified by numbers 1 to 8 on the nozzle changer. The nozzle garages
in the magazines are numbered consecutively from 1 to 12 (see Fig. 5.1 - 2). 5
PLEASE NOTE 5
Special magazines are available upon request (contact SIEMENSDEMATIC SD EA 1 for details)
and will be numbered differently. 5
Picking up a nozzle 5
– The Collect&Place head Z axis 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 Collect&Place head Z axis moves down and sets the nozzle down.
– The locking plate closes.
– The Collect&Place head Z axis moves up.
Discarding defective nozzles 5
– The Collect&Place head Z axis 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 device.
– The Z axis moves up again and the nozzle is stripped from the sleeve by spring wires.
– The nozzle drops into the container (item 3 in Fig. 5.1 - 1).
