Abstract:
We are pleased to introduce a new Coverage
Checker using ultraviolet light.
1. Background of development
Coverage Checker has been designed for easy and precise
coverage measurement in place of human eyes. It is mainly
used for the quality check on automobile parts after shot
peening or blasting.
However, some customers asked us to make the creation
of a “recipe†easier. The recipe is a set of measurement
condition and calibration line between the number of pixels
in an image and coverage% on the parts surface determined
by human eyes.
In order to simplify recipe creation, the surface condition
before shot peening should be uniform under all measurement
conditions.
So, we considered combining the fluorescent paint “Peen
Scan Pen†handled by Electronics Inc. with Coverage Checker.
As a result, we have developed Coverage Checker UV light
version (Fig. 1) with a coverage measurement system that can
respond to one fluorescent paint with only one recipe.
