5.2.2 Main Parts/ Unit Overview
5.2.2.1 Z Axis Drive
1. Mounting for Z Axis
2. Incremental measurement system
3. Primary part of linear motor
4. Secondary part of linear motor
5. Ceramic jaw
6. Light barrier Z-down (analog)
●
The Z Axis is supplied with 40V/ 3,28A from the MHCU.
●
The incremental reader head has an EEprom on the connector to store statistic and axis data.
●
The Z Axis unit and the raceway are complementary parts, it is not possible to change one of
the above mentioned parts.
5.2.2.2 Z Axis
1. Raceway
2. Segment 1
3. DP ball bearing
4. Light barrier Z-down
●
The Z-drive is not a spare part!
●
The light barrier Z-down is not a spare
part!
5. Jaw
Functionality of the Z-drive
●
The ceramic jaw is mounted to the primary part of the Z Motor for mechanical docking of the
DP drives.
●
The analog Z-down sensor is located at the placement position for recognition of the Z Axis
set down position.
●
When the Z Axis springs into place, this sensor sends a signal to the axis controller card
(MHCU) The "light barrier down" signal is directly linked to the measurement signal of the
Z Axis incremental encoder.

5.2.2.3 Component Sensor
1. Power/ data supply cable
2. Mounting to housing
3. Laser beam
4. Transmitter and receiver unit with
protected prisms
●
The component sensor is installed in the
pickup-placement position on the C&P20 P
Head.
●
The sensor is fixed to the head with two
screws (2).
1. Downwards (A) or upwards (B) movement
2. Nozzle
3. Component
4. Reading out the Z position, if the laser
beam is interrupted (A) or has been
released again (B)
Component Sensor Functions
●
The component sensor determines the
component and nozzle height during the
placement process.
●
The component sensor signal is directly
linked to the measurement signal of the Z
Axis incremental encoder for recording the
position.
5.2.2.4 Retract Unit
1. Compressed air connection
2. Solenoid valve
3. Pneumatic cylinder
4. Mounting of retract unit
5. Actuator to move the Z Axis
Retract unit Functions
●
The retract unit is installed on the Z Axis
and is responsible for protecting the Z Axis
from damage by moving it into a safe
position in the case of unexpected events
e.g. power cuts or machine shutdown.
●
The retract unit is fixed with two screws
and can be easily replaced during service
work.
