8.10 Calibration
Overview
The following values are determined during calibration of the component camera:
●
Relation of camera pixel size to resolution of machine measurement system (X, Y).
●
The camera center point in the X and Y directions
●
Rotation 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 (seg-
ment1). The target is a fixed value (X=0 and Y=‑105mm) to which an offset value (from the
head calibration) is added.
●
Segment offset top: the top segment offset involves turning the calibration tool in the compo-
nent camera in 0°, 90°, 180° and 270°. The value determined is that of the rotating center of
the nozzle tip in relation to the component camera center in the X and 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 ro-
tating 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.
