7.1 Nozzle Changer

Nozzle changers can greatly increase the flexibility of the placement heads for processing differ-

ent types of component. If the placement program requires a nozzle change, then the placement

head automatically returns the old nozzle to the nozzle holder and picks up the new nozzle. Noz-

zles that were separated out during the vacuum check can also be quickly changed.

It is significantly more exact and faster to pick up nozzles from a nozzle changer than would be

possible manually. When placing small components, it is essential to minimize the radial eccen-

tricity during nozzle rotation.

7.1.1 Configurations Options for Nozzle Changers at the SWS

Depending on the placement head used a second bank can be configured as an option.

The main difference between the nozzle changers at an SWS and those at locations without SWS

lies in the usage of a different reject bin (03070917-01). The nozzle changers for the SWS are

structured alike, the only difference is the mirror-inversed position of the reject bins at the left-hand

locations (1 and 3) and the right-hand locations (2 and 4).

7.1.2 Nozzle Changer for the 20 Segment Collect&Place CA Head

Fig. 7.1 - 3 Nozzle changer for the 20 segment Collect&Place CA head

This nozzle changer can hold up to 6 magazines, each with 12 nozzle holders. The magazines

are seated on a common support. They are centered using two parallel pins and fixed in place with

4 snap fasteners.

Microswitches monitor whether the magazines are seated correctly on the body of the nozzle

changer in order to prevent the placement head colliding with a protruding magazine. All maga-

zine locations must be filled since the safety circuit stops the machine in response to missing mag-

azines or magazines that are not seated correctly.
