Overview

Applicat ion
8.2.1 Application
The CPP head can be used in the following machines:
▪ X series (X2, X3, X4, X4I)
▪ SX1 - machine with one gantry
▪ SX2 - machine with two gantries
▪ SX4 - machine with four gantries
CAUTION
Head exchange X series
When replacing the TwinHead with a CPP head with MTC2 in this placement area, you need
to fit a bumper extension, to limit the Y travel range. After switching the machine back on, you
then need to redetermine the machine zero point and the travel ranges.
When you use a TwinHead again, you need to remove the bumper extension.
CAUTION
Risk of head crash!
When installing a CPP head with a stationary camera, this needs to be fitted in the top position
otherwise there is a risk of a head crash!

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.
