Calibration
Overview
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 and Y direc
-
tion" 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 (segment 1).
The target is a fixed value (X=0 and Y=
-
105 mm), 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 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 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 rotating center point of
the nozzle tip when the Z axis is extended in relation to the PCB camera. Segment 1 forms the ref
-
erence (X=0, Y=0) to the other segments.
The nozzle scan can be enabled or disabled in the soft
-
ware. Different scanning levels and the corresponding
actions for the errors in individual nozzle types can be de
-
fined.

Calibration Procedure (C&P, CPP, DLM)
C&P calibration procedure
► Switch over to the operator level Service (Customer).
► Switch over to the Service menu and select Ma
-
chine calibration or Automatic calibration (depending
on SW version).
► Select 8. Head and cameras and click on Next.
► On the next page, select the gantries on which the
heads to be calibrated are located and then click on
Next.
► The next step is to check the calibration conditions
(nozzle, calibration tool etc.). Follow the instructions
provided.
After this step, calibration will begin. All required interme
-
diate steps (head height etc.) will be performed automat
-
ically.
