3.13 Single PCB Conveyor
[00119625-xx] Modular single conveyor II, 2380 mm
[00119626-xx] Fixed conveyor side right, HF/X/CA/D-Series
[00119628-xx] Fixed conveyor side left, HF/X/CA/D-Series
[00119629-xx] Conveyor width 250/508 mm, HF/X/CA-Series
In its standard version, the placement machine is equipped with a PCB single conveyor. The PCB
dual conveyor is available as an option ex factory (see section 3.14
, page 189). 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. There is a lifting table for clamping the PCBs in each
processing area. The PCB conveyor width can either be set from the user interface or preset in
the placement program.
