5.2.7 Calibration
5.2.7.1 Calibration
Calibration - Overview Description
This calibration step first measures the component camera. This determines the relationship of
"camera pixel size to resolution of machine measuring system (X, Y)", the "camera center point in
X/Y direction" and the "torsion angle of the CCD sensor in the camera". This is following by
determining the head offset and the segment offsets for the top and bottom.
●
Head offset: the head offset is the distance between the PCB camera and the nozzle
(segment1). The target is a fixed value, to which an offset value (from the head calibration) is
added.
TX micron only: During the placement cycle the head offset is periodically checked and
calibrated.
●
Segment offset top: the top segment offset involves turning the calibration tool in the
component camera in 0°, 90°, 180° and 270° steps. The value determined is that of the
rotating center of the nozzle tip in relation to the component camera center in the X/Y
direction.
●
Segment offset bottom: the bottom segment offset involves recording and measuring the
calibration tool in the 0°, 90°, 180° and 270° positions. The value determined is that of the
rotating center point of the nozzle tip when the Z Axis is extended in relation to the PCB
camera. segment1 forms the reference (X=0, Y=0) to the other segments.
