Automated high-speed inspection
The Optisort machines that he then developed use camera technology combined with automated infeed equipment and extremely fast computing systems. Seeing the speed of such an installation in action is impressive: Coming out of a bunker system and transported by a push-bar conveyor, the test objects are fed into the system individually and, if necessary, in the right position. Resting either on a glass plate, a special metal plate for screws or a conveyor belt, they are taken past a series of cameras. 360° inspections with four cameras are also possible. Good parts are actively discharged, defective parts are separated out.
All this happens at a speed that the human eye can hardly keep up with. "The installations inspect several hundred parts per minutes, and sometimes more than 50,000 per hour“, says Thomas Rothweiler. At the same time, they are also very flexible as they can inspect different components: "Each machine typically inspects 200 to 300 products. " There is a special inspection programme for for each particular product.
