No need for rulers: new vision system inspects the tiny and the weightless
Anyone in the micro-assembly and testing industry knows the difficulties in handling the components: they're tiny, almost weightless, and highly sensitive to electrostatic charge. Inspecting and sorting these parts for assembly can be a painstaking task.
When sorting parts, an operator traditionally places the parts into a vibratory bowl feeder, a bowl with ridged sides. When the bowl is switched on, the parts jiggle and separate themselves on the ridges, but micro-assembly components tend to stick together or have too little mass to be transported by vibration. Other alternatives, like robotics systems or manual supply, often lack either speed or accuracy. In micro-assembly there is a need for a system that combines the functions of feeding, orientation and inspection of parts.
