The Twin head consists of two identical modules
which work according to the Pick&Place principle.
The second P&P head is rotated 180 degrees.
For the Twin-head, new nozzles (Type 5xx) were
developed. However, the nozzles of the
Pick&Place head type 4xx and the nozzles of the
Collect&Place heads type 8xx and 9xx we can use
with an adapter.
Placement accuracy (X/Y) 35µm by 4 sigma with IC camera
Placement accuracy (X/Y) 30µm by 4 sigma with FC camera
Placement accuracy (Angle) 0,07° by 4sigma
Placement speed 3500 cph
Maximum component size: 50 up to 40 mm single measurement on both segments
69 up to 10 mm (multiple measurement on both segments)
125 up to 10 mm ( multiple measurement on one segment)
200 up to 125 mm (multiple measurement with restrictions on one
segment )
Max. component height 25 mm
Placement force 1 - 15 N
D-Axis / Resolution direct drive / 0,001 degree
Z Axis / Resolution Linear motor / 0,5 µm
Travel range Z axis app. 60 mm
Nozzle types 5xx (4xx, 8xx, 9xx with adapter)
Distance between the segments approx. 71,00 mm
Max. weight of component 100 g
Option high force Twin head placement force max. 30 N (only X series)

9.1.2.1 Vacuum generator Twin- Head
9-2: Vacuum generator
The vacuum generator automatically controls the
vacuum, air blast and the zero balancing position
(middle position-->no vacuum and no air blast) for
the segments, with the aid of an iron core and
inductor.
Legend
1. Compressed air input
2. X series, D3: Cooling for X linear motor
D1: Discharged air to silencer
3. Output vacuum - vacuum is passed through
the D-axis motor shaft and then to the nozzle.

9-4: Filter for the vacuum system (example of Twin segment version 03
shown)
Legend
1. Filter for the vacuum system on the Twin-
head.
The Filter is mounted on the return unit and used
as an attenuator to control the vacuum. The filter
with the additional volume reduces the oscillation
of the vacuum generator and guarantees an
accurate vacuum and air blast supply. The filter is
serviced at regular intervals, which must be
adhered to (see maintenance guide).
