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.

6.1.1 Mechanical Structure of X and Y Axes

Please Note: X and Y Axes have the same basic mechanical parts.

6-2: Mechanical structure "Gantry"

Legend

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)

NOTE:

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.
