The seven power cables take the form of flexible ribbon cables, four of which are needed for the
collect&place head. They run beneath the cover in the machine frame (see item 1 in Fig. 4.2 - 5
),
between the head board on the head mount and the gantry board. 4

The other three ribbon cables supply power and transmit control signals for the gantry axis drives.
They connect the gantry distributor (see item 1 in Fig. 4.2 - 5
) to the X/Y distributor (item 2 in Fig.
4.2 - 4
). 4
The gantry is supplied with compressed air via seven compressed air hoses. The lines are con-
nected to the compressed air distributor (see item 2 in Fig. 4.2 - 5
). They run in the trailing cable
and end at the inlet couplings (see item 7 in Fig. 4.2 - 4
) on the motor bracket (see item 9 in Fig.
4.2 - 4
). Seven compressed air lines continue from the outlet couplings (see item 8 in Fig. 4.2 - 4)
to the collect&place head. 4
The X-axis motor (see item 5 in Fig. 4.2 - 4
) moves the head mount (see item 4 in Fig. 4.2 - 4) in
the x direction with the aid of a toothed belt (see item 6 in Fig. 4.2 - 4
). The mount is fixed to three
shuttles (see item 1 in Fig. 4.2 - 6
) on the two recirculating ball screw units (see item 2 in Fig.
4.2 - 6
) on the underside of the gantry. This layout guarantees that movement of the X-axis is both
precise and generates very little friction. 4
