With the increasing demand for 0 ppm in the automotive industry, Davon has made 100% vision inspection of customer identified critical characteristics part of our process for many of the steel stampings we produce. This allows any product that has had excessive distortion from heat treatment or damage caused by bulk processing to be eliminated from inventory and scrapped before being delivered to a customer. Hand sorting parts has always been a time consuming and expensive endeavor and with the inclusion of human error was oftentimes not 100% effective.
Davon’s utilization of vision inspection currently gauges parts to within ± 0.0015 of an inch (±0.038 mm), or better, on any number of critical dimensions at a time with our seven vision inspection sorting machines. We are able to achieve sorting rates of 1,200 to 4,000 pieces per hour depending on the application. We can accomplish these high speeds in conjunction with this accuracy by maintaining seven dedicated machines four unique types of inspection systems. These have been built to be flexible and to achieve any possible outcome. Each system has its own advantages and depending on the part being sorted we use the system best suited for the cause.
Our vision equipment includes one indexing rotary table, three constant motion rotary tables, and four conveyor systems. The indexing table allows us to fixture parts and hold them in a precise location every cycle – the disadvantage of this system is that speed is sacrificed. The constant motion rotary table allows us to sort at a much faster rate than the indexing table while not sacrificing any accuracy – the disadvantage to this table is not all parts’ critical dimensions will be visible without fixturing. Finally, the four conveyor systems that we have at Davon are used to sort parts at very high speeds and we can run applications on these that require up to four cameras all inspecting one part.
