Optical Examination of Pin Insertion Process

Abstract

In the electronics industry compliant pins are gaining ever more prominence mainly in the automotive industry. In this paper, a new, dedicated optical pin insertion process control method is described. Using a specific automatically synchronized video recording technique, the elimination of the components of a moving mechanical system and minimization of the number of cameras is demonstrated. A simple algorithm is given for the selection of the appropriate pictures for inspection and for pin detection. The reliability and the accuracy of the method and the experimental system are also demonstrated and proved. Significant reduction of failure rate was demonstrated.
