Wire processing apparatus employs a conveyor for transporting wire segments to a series of wire processing machines which strip insulation from the wire segment ends and then subsequently attach electric terminals to the stripped ends. A quality control device located between the insulation stripper machine and the terminal attachment machine inspects each stripped end and, if it does not meet desired tolerances, sends signals which prevent the terminal attachment machine from operating upon the defective stripped end as the conveyor moves the wire segment therepast. The quality control device comprises an illuminated field at which the stripped end momentarily stops, an optical lens opposite the illuminated field for providing an optical image of the stripped end, and a converter for converting the optical image to an electronic image signal. Solid state electronic circuits compare the image signal to a reference signal, provide an error signal if the stripped end is defective and store the error signal in a memory circuit. The error signal, if present, is recalled from the memory at the appropriate time and converted to an output signal which prevents the downstream terminal attachment machine from operating on the defective wire end. |
