1 Two individual images 2 Composite image of the approximate position
Fig. 52326
Four pictures are always taken to record the precise position. A
new image is created by placing the four individual images on
top of each other.
The images are always recorded at a distance of 333 mm (dis-
tance between the sheet surface and upper edge of covering
hood) to ensure the precise position recognition takes effect.
Four flashes, which are activated separately, are used to record
the fine position image. They are arranged at an angle of 90° to
each other and, in this way, allow the parts to be illuminated
from all sides in order to create the shadows required at the
edges of the parts.
The individual images are placed on top of each other (precise
to the pixel) in order to retain the dark shadows and reduce the
light reflexes or eliminate them entirely:
