Bearing Ball Machine - based on OEBSYS (1989)

ICRA has implemented an inspection system to check bearing balls right after manufacture for defects with an accent on hardness, surface uniformity and to a lesser extent for size, although this is a by-product of the proposed inspection process. Faulty balls will be automatically rejected and ejected off the assembly line. The process serves to guarantee the user (Detroit based automobile industry in a first instance) a “perfect” bearing ball in its enclosure, mainly a ball bearing. The same principle of the system can be used for inspection bearing races.

The heart of the hardware system is the OEBSYS II Line Scan Camera interface boards specified for the application because of speed issues associated with the timings.

Both 7-slot channels of the computer are equipped with the OEBSYS II controller digitizer board. One board set is be used to look for the bright errors while the second board set is scanning for dark and grey ball errors. Because both 7-slot panels of the enclosure behave as separate computers, the signal from the cameras is split into the separate board systems. Either system channel may reject a ball and both will keep statistics that can be merged for off-line analysis.
