Overview
6.1 Overview
The gantries of the SIPLACE X machines consist of one X and one Y axis. Both axes are driven by a
linear motor which is equipped with an integrated temperature sensor. These temperature sensors only
monitor the motor coils. Viewed from the direction of transport, the Y motors move from the right to the
left, in a more positive direction (new coordinate system) and the X motors move from the input conveyor
to the output conveyor, in a more positive direction. The coordinate origin is exactly in the center of the
machine. The placement heads are mounted on the head plates of the respective X axis.

Description
6.1.1.1 Description
The head mounting plate with the placement head is moved in the X direction by the linear guidances,
which are mounted above and below the secondary part of the linear motor. The Y axis moves the entire
X axis gantry with the placement head.
1 X gantry made of carbon fiber 6 PCB camera mounted under the gantry
2 Head mounting plate with integrated
primary part of X axis linear motor
7 Boards (head interface with Vision board
below - vertical - the head adapter board)
3 Incremental scale 8 X trailing cable
4 Linear guidances for X axis (above/
below)
9 Temperature sensors
5 Secondary part X axis (magnet)
NOTICE
To improve placement accuracy, the temperature sensors compensate the offset between the
PCB camera and the nozzle, based on the temperature of the head mounting plate.
