3.4.8.2 Nozzle Changer for 12 Segment C&P Head
Optionally, a nozzle changer can be installed for each C&P head. This enables the nozzle configuration
to be changed quickly, thus allowing the Collect&Place head to be quickly adapted to the needs of the
placement process.
The nozzle changer consists of at least one and up to five magazines, each of which is equipped with
up to twelve nozzle garages. The magazines are seated on a common support and each magazine is
centered using two pins and is fixed in place with a spring hook.
Each garage can be configured with different nozzle types.
3.4.9 SIPLACE Vision
The 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
Intuitive graphical user interface
Geometric description of components at the machine
State-of-the-art digital camera hardware
Homogenous illumination of camera Field of view and components
Each C&P head has its own digital component camera.
