Abstract

Disclosed is an automated three dimensional inspection cell and method to perform non-contact measurement and inspection of objects (or units) to determine their presence, absence and dimensions. The automated inspection process uses cameras and range sensing devices to enable three dimensional inspection of the objects in order to insure that they are properly aligned and assembled during manufacture. A block diagram of inspection cell 10 is shown in Figure 1. Communication between detection system 2, robot controller 4 and height measurement system 8 is centralized through vision processor (or cell controller) 6. External to cell 10, vision processor 6 interfaces with manufacture assembly systems (not shown) such as a conveyor system which provides the necessary signals to initiate the inspection process. After inspection, any resulting data from cell 10 is relayed to a central processing system (not shown) in order to provide feedback to operators of assembly stations.
