9.8 Segments

The revolver head has a total of 12 segments. The segments slide on the guide shafts of the revolver head.

Evacuation of the segment or nozzle takes place via the vacuum tube of the revolver head.

As the revolver head cycles on, the segments bring the picked-up components to the individual work stations

of the revolver head. At each work station the actions required for mounting the components will be

performed. The following revolver head stations are work stations:

At revolver head station 7 you can remove and fit segments using the segment removal tool.

9.8.1 Segment Versions V1 and V2

At the present time you can use two different segment versions at the revolver head:

–

Segment version 1, designated E5.2 and

–

segment version 2, designated E6.1

NOTE

When performing servicing or routine maintenance work, make absolutely sure that you use only the spare

parts for the installed segment version. You must not use Version I spares with Version II segments, and vice

versa.

Differences between segment versions V1 and V2 (Fig. 9.8.2)

The above table shows the most important differences between Versions 1 and 2!

The modified nozzle seating in Version 2 means that so-called "long" nozzles can be used. With these

nozzles the placement shadow can be reduced and components as tall as 6 mm can be placed.

NOTE

This change in the design of the nozzle seating means that only nozzles for the version in question can be

used (in other words, nozzles are version-specific).
