Machine Vision in Pattern Recognition & Orientation
As shown in adjacent photograph the object to be inspected is a shaft with a line marking on the end face. This presence & orientation of this marking during the assembly process of the shaft, when it is placed into a fixture is very important. The machine vision system checks the presence as well as the orientation of this line marking. By interlocking the Ok / Not Ok signal from the vision system with the fixture locking mechanism the assembled is either allowed or not allowed. Thus machine vision helps in incorrect subassembly of the shaft and prevents problems arising out of at a later stage of manufacturing a complete assembly.
