The Y axis essentially consists of the following main modules:
– Y axis linear drive with permanent magnet (item 5 in Fig. 3.7 - 3
, page 124) and adapter
plate (item 3 in Fig. 3.7 - 3
, page 124)
– Y axis guide system (item 4 in Fig. 3.7 - 3
, page 124)
– Y axis measuring system (item 6 in Fig. 3.7 - 3
, page 124)
The Y axis is driven by a linear motor. The secondary part of the drive is made up of permanent
magnets and is mounted on the machine frame. The primary part is bolted to the gantry (adapter
plate). An anti-crash circuit prevents the traversing paths of the gantries meeting.

3.8 PCB conveyor system
The machine is supplied with a PCB single conveyor as standard. The PCB dual conveyor is avail-
able as an option from the factory (see Section 3.8.7
, page 134). The left or the right side of the
PCB conveyor can be used as the stationary side, as required.
The conveyor belts are driven by DC motors. The lifting table for clamping the PCBs is located in
the processing area. The PCB conveyor width can either be set from the user interface or preset
in the placement program.

3.8.2 Description
For placement, the PCB is clamped from below. The distance between the top of the PCB and the
placement head thus remains unchanged for each PCB, and is not dependent on the thickness of
the PCB. The placement rate is thus independent of the PCB thickness. The PCB fiducial center-
ing can also be optimized. Since the distance between the PCB surface and the PCB camera re-
mains the same, the PCB camera is always focused on the PCB surface with the same sharpness.
The PCB fiducial contours are optimally mapped on the CCD chip of the PCB camera.
