Configura tion

8.2.2 Configuration

The CPP head with 12 segments can be configured as follows:

▪ Low installation height (CPP_L)

▪ High installation height (CPP_H)

Requirem ents

8.2.3 Requirements

The following requirements need to be met for using the CPP head in X series machines:

▪ A364 axis controller with servo amplifier SDS120-1.5Z2 or HCU (Head Control Unit)

▪ Station software ≥ SW702

▪Box PC

▪ Head plate for CPP head

▪ X tables and X feeders

▪ Addressing the nozzle changer via the CAN node module or the FCU (Feeder Control Unit)

Technical Data

8.2.4 Technical Data

The component spectrum depends on the component camera fitted and the resulting placement mode.

Special Features of CPP Head

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.

Overview Principle of CPP Head

267 Student Guide SIPLACE X-Serie and X4I SW70x (AL2)

▪ 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 higher 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 higher placement reliability.

▪ Robust nozzle interface and nozzle magazine

▪ Nozzle types 20xx and 28xx with corresponding magazines

Principle o f CPP Head

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.

▪ Energy and data from the stationary part of the head are transferred via a contactless energy

transformer and a contactless data transformer to the control board (Single Core Solution) and 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.
