Legend – main X axis modules
The following modules are installed on the head mount (2):
PCB camera (6)
Head board with Vision board (7) (head interface, head adapter)
Incremental encoder
C&P20A head, CPP head or Twin Head
The gantry arm (1) is made of carbon fiber. This gives the gantry arm high torsional rigidity with minimum
weight. The X axis is driven by a linear motor. The secondary part of the drive consists of a permanent
magnet and is fixed to the gantry arm, while the primary part is screwed to the head mounting plate.

3.2.8 SIPLACE Vision
The new digital SIPLACE Vision solution is another step towards the satisfaction of customer demands
for greater speed, flexibility and robustness.
Advantages of the digital Vision system:
Robust and fast computing algorithms
Flexible measurement processes
Self-learning graphical interface
Geometric description of components at the machine
State-of-the-art digital camera hardware
Homogenous illumination of camera field of vision and components
Each C&P head has its own digital component camera. For Twin Heads, a stationary camera is installed
in the machine.
