8.2.5 Special Features of CPP Head

 There are various placement modes: C&P mode, P&P mode and mixed mode.

 Symmetrical head design: The head can be fitted on the left or right.

 Component spectrum for component 01005 – 50x40 mm

Component height max. 11.5 mm

 The holding circuit has one venturi nozzle for each segment.

→ No more interference between the segments.

 Each segment has its own valve. Each segment can therefore be switched off separately.

→ This reduces the air consumption.

 Each segment has its own motor with incremental measuring system.

→ The segments can be rotated independently of one another.

 The light barrier down is integrated into each segment.

→ This leads to a high placement reliability. There is no need to adjust the light barrier down. This

design is more robust, since a movable cable is not required.

 A digital pressure control valve enables faster switching times between vacuum and air blast.

 The component sensors in the pickup&place position are more robust. The prisms have mechanical

protection.

→ This leads to a high placement reliability.

 Robust nozzle interface and nozzle magazine

 Nozzle types 20xx and 28xx with corresponding magazines

8.2.6 Principle of CPP Head

 The CPP head functions according to the Collect&Place principle, like the C&P12 head, whereby the

additional operating modes Pick&Place and mixed mode help to extend the component spectrum.

 Each segment is equipped with its own DP drive and an incremental measuring system, to allow

angle adjustment while the star is revolving.

 The power and data are transferred from the stationary part of the head via a contact free ED

transformer to the control board (Single Core Solution - SCS) for the DP drives.

 In addition, each DP drive has a light barrier Z down. Together with the secondary part of the linear

motor (Z axis), there is no cable which is moved with the Z movement.

 The so/called valve terminal is used to switch the supply pressure on and off for each segment.

 In the pickup and placement position, the Z axis moves with the complete DP drive unit upwards or

downwards.

 In the pickup cycle, the vacuum is increased by the holding circuit, using a pressure control valve.

During placement, the vacuum is eliminated by the holding circuit, with an air blast, and the

components are blown off.

 In the pickup/placement position, the standard component sensor is used to check the presence and/

or height of the components on the nozzle, both before and after pickup/placement.
