The AX Base contains a board transport unit, run-in section, where boards from the
previous machine are received, and a run-out section, where boards are transferred to the
next machine. The trolley lift is integrated in the front side of the base. At the rear side of
the base the placement controllers are located which control placement robots and place-
ment heads.
Machine base
The AX Transport feeds the boards from the run-in section to the run-out section in a
number of steps. After each step, the placement robots will place components on all the
boards in the transport area.

The pick and place module of the AX has three sub modules: the placement robot,
the placement controller and the placement head. The AX can be equipped with two
types of placement robots or a mix of the two; the standard placement robot and
the compact placement robot. Both placement robots use the same hardware and
software and achieve the same specifications. A compact placement robot is half
the width of a standard placement robot. This allows scaling the AX platform in out-
put while maintaining the available feeding positions.

Each placement robot is fitted with a placement head. The placement head
executes the following tasks:
Z-movement
Rz-movement
Component alignment
Board alignment
Force sensing and control
Trolley and feeder detection
Toolbit exchange unit detection
Board warpage correction
Placement head
The Z-stroke uses a linear motor. This linear motor controls the pickup force,
placement Z-speed and placement dwell and impact force.
Board warpage correction
When a board enters the placement area, every placement head measures the
impact position and calculates the appropriate Z-height to correct for any applicable
board warpage. This adaptive Z-height feature enables that the appropriate
placement dwell force and impact force is well within the tolerance of process
requirements.
AX Placement head force specifications
Placement force range 2N to 8N, lower forces with restrictions
Programmable placement force stepsize 0.1N
Placement force control by linear motor current servo loop
