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.
