Align the nozzle changer so that the moving spring hooks always point toward the operator,
while the retaining clamps always point toward the PCB conveyor.
7.1.3.5 Functional Description
The nozzles are located in nozzle garages and are fixed by a movable locking plate. A pneumatic
cylinder moves the locking plate by 6 mm. Depending on the position of the locking plate, all noz-
zles are either clamped into place or released. The default position of the locking plate, i.e. if there
is no nozzle change in progress, is "closed".
Every magazine of the nozzle changer has a positioning fiducial for position detection. The mag-
azine locations are numbered from 1-5 for the nozzle changers of "row 1" and from 6-10 for the
"row 2" nozzle changers (see fig. 7.1 - 12
). The 12 nozzle garages in the magazines are also num-
bered consecutively (see fig. 7.1 - 15
).
NOTE 7
Special magazines can be made after consulting with ASM Assembly Systems GmbH & Co.KGa
and receive a seperate marking.
Nozzle Pick Up 7
– The Z-axis of the Collect&Place CA head moves downwards.
– The locking plate (item 2 in fig. 7.1 - 15
) opens and releases the nozzles.
– The nozzle is taken up by the sleeve of the Collect&Place CA head.
– The Z axis moves up.
Placing a Nozzle Down 7
– The locking plate (item 2 in fig. 7.1 - 15) opens and releases the nozzles.
– The Z-axis of the Collect&Place CA head moves downwards and places the nozzle down.
– The locking plate closes.
– The Z-axis of the Collect&Place CA head moves upwards.
Rejecting Defective Nozzles 7
– At the reject unit (item 4 in fig. 7.1 - 12 ) the Z-axis of the Collect&Place CA head moves down-
wards by 14 mm and transfers the defective nozzle to the hole of the reject unit.
– The Z axis moves up again and the nozzle is stripped from the sleeve by spring wires.
– The nozzle drops into the reject bin.
