3.3 Gantry
The placement system is equipped with four gantries. These enable the four collect&place heads to be
positioned in the x and y directions with great accuracy and independently of one another.

Legend
The structure of the gantries makes them very torsionally rigid. The precise mechanical movement of the
axes is produced by recirculating ball screw units.
High-precision positioning systems determine the positions of the X and Y axes. To do this, the
graduations on metal scales are optoelectronically scanned and the track signals are sent to the axis
control in the control unit.
Direct drive units are used to position the placement heads in the x and y directions. This eliminates
friction losses, for example, which are typical when complex gearing is used. In addition, there is none
of the wear that can significantly affect the accuracy of positioning systems over the course of time.
X-axis drive
A toothed belt is used to directly convert the rotary movement of the X axis turning motor into a
translatory movement of the placement head in the X direction.
Y-axis drive
The translatory movement of the placement head in the Y direction is generated by a linear motor.
