A VISION SENSING BASED ASSEMBLY ROBOT AN ON FIELD APPLICATION

The need of increasing the flexibility of automated manufacturing systems has given rise to the rapid growth in the number of artificial vision applications in the factory over the last year. Machine vision, based on the processing and interpretation of electro-optical images, has been used increasingly in a number of different programmable automation systems, in on-line/off-line inspection, in material sorting and handling, in arc welding and in assembly tasks. This paper discusses an application in Alfa Romeo of a vision based industrial robot in assembly operations. The vision system, based on a hierarchical structure of 16-bit microprocessors with wide memory-addressing capabilities, makes possible the practical addition of gray-scale capability to multiple cameras and performs sophisticated image processing and recognition algorithms. The vision system has been integrated with a Milacron Cincinnati industrial robot. The vision-robot system is operating in Alfa Romeo in a prototype application, performing the assembly and screwing of the hinges of car doors.
