Automatic workheads do not detect rejects without the aid of complex sensor systems. A defective part arriving at the workhead causes a jam and the workstation is down for a period of time. These events are minimized by having high component quality levels and restructuring the inspection routines. Most manual assembly systems have three inspection stages - goods inward, during assembly, and upon final assembly of the product. Parts or assemblies which do not fall within quality bands, at each of these stages, are rejected. Automatic assembly equipment requires higher quality components and, therefore, greater quality control is required at the goods inward stage than for manual assembly. Automatic assembly equipment, fed with high quality parts, gives a higher quality finished product than manual assembly. The consistency of an automatic system, aided by high quality parts creates a high quality product.
