Ball Bearing Vision System (BBVS)

The system is designed to allow the end user to quickly and economically implement a ball presence/absence detection feature on a ball bearing assembly machine. The system is provided with the hardware components and application software required to implement the detection feature. The user needs only to supply the necessary bracketry to mount the components. The camera, lens, and fiber optic ring light are provided, mounted to an extruded aluminum column. Each component can be independently positioned at any point along the column. The optical center to the column center is set at eight inches. The electronics cabinet consists of an industrialized, Pentium-based processing platform, CRT, keyboard, camera, digitizer, and OPTO-22 modules to interface to the customer's PLC.

The applications software has been developed from a library of routines which have been utilized over a number of years to provide specific presence/absence detection capabilities for turnkey full custom systems produced by IISD. The highest performance and most robust routines have been integrated into this package. A user-friendly interface has also been provided to allow a customer to quickly implement his specific ball detection application. FEATURES
