Study on Inspection of Circular Parts Used in Mechatronics

Abstract

Abstract. Classical methods for the inspection on a production line of circular profiles are characterized by a reduced flexibility, making them extremely expensive. This work provides a study on vision systems used for determining deviation from circularity of components used in mechatronics. The paper present a vision system that analyzes and processes the captured image of circular parts in an automatic mode in order to undertake the dimensional inspection. The proposed system has been tested for MR522ZEZO class miniature bearings. The inner diameter of MR522ZEZO bearing is 2 mm, which makes it unavailable for dimensional control by conventional methods. Experimental results show that the proposed system is able to perform an accurate dimensional control in automatic mode while ensuring high flexibility for distinct types and sizes of mechatronic components with circular profiles.
