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.
