Vision inspection design for systematic production of needle beds: an industrial application

Abstract

The increasingly standards of the electronic industry, especially in Printed Circuit Boards, make In-Circuit-Test Machines one of the most important systems on the production lines. With this, the pressure on the In-Circuit-Test Machines production to meet this strict requirements it is getting bigger every day. To react to this pressure it is necessary to update, in a technological point of view, the manufacturing process of the In-Circuit-Test Machines, particularly its needles bed. To do so it is necessary to automatize the process. This automatization of the process was divided into several sub-functions, being one of them, the vision System. This system is the focus of this paper. The problem was analyzed, several solutions were studied within the state of the art and one original solution was proposed to solve the problem. The decision process followed engineering criteria’s and culminated on the proposal of a solution to solve the identified problem. Applying engineering tools to understand which approach is better when implementing a Vision Systems proved to be a good method.
