System for identifying and marking individual automotive tires including
use of a light sheet sensor enabled image processing for the
identification of the tire type and the marking spot. The height profile
of the raised symbols on the tire sidewall can be measured using the
light sheet sensor and matched to a library of reference profiles stored
in memory. The light sheet sensor measures the height profile of the tire
sidewall for identifying the tire and for selecting the marking spot and
where the light sheet sensor and a laser are mounted on a swivel arm. The
light sheet sensor can be incorporated into a single- or multi-station
system. A marking laser is adapted for engraving markings on a specific
spot in rubber on the side of a tire via laser radiation after the type
and size of the tire and a marking sport has been identified by image
processing.
