Screws, washers or other mass-production goods in the connection technology, which are mainly used in the automotive and aviation industries, are inspected and sorted by this system from GEFRA GmbH with the help of machine vision from Stemmer Imaging at up to 600 parts per minute. Due to the area of use of the inspected parts, the highest level of reliability in quality testing is mandatory.
In one of the largest systems implemented, twelve cameras at six stations inspect screws for fastening brake lines in vehicles. It is important that the tolerances of all geometric sizes, including the quality of the thread, are strictly adhered to in order to guarantee 100% functionality.
