A MECHANICAL DEVICE USED TO IMPROVE THE VISION INSPECTION IN SMALL SCALE INDUSTRY

The dimentional and quality control tasks have to be performed at the onest of any assembly line. Defected surface even small ones leads to non-conforming of the final product. The automated artificial inspection has proved its acceptance due to its significant advantages. The first aim of this paper, is to describe the operational and design features of the mechanical device that could be integrated in the vision inspection systems. The device contributes positively to improve the inspection efficiency as it is integrated in the vision systems. The designed mechanical device will be used to properly fix, orients, and presents the inspected objects in a vertical and horizontal plans to the acquisition system, in order to provide more accurate feedback information regarding the inspected objects. This arrangement can be achieved by linear and rotary motions provided by the device. The device drives the objects in a linear motion along the measurement direction in the front field of the acquisition system. While the rotary motion is necessry to rotate the object in order to ensure a coplete scannunig of entire surface of the inspected object. It allows the CCD cameras to capture adequite images during each rotation from both vertical and horizontal plans. The design and research has been made on basis of a good understanding of the vision concepts and applications. The device design is relaible, simple in construction and has flexible operation. It was tested with two different shapes: cylindrical and prismatic. The obtained images of the inspected surface (with scanned pits, texture, scratches, cracks, and finishing) demonstrated its capibilty for accurate inspection if integrated with the vision inspection systems. The design and operational characteristics are presented in the next sections
