Abstract

The bonding of the ends 1, 2 of an insulated twisted pair of wires 3, 4, having respective insulations R, G of different colors, e.g., red and green, often requires that at least one of the wires be in a proper orientation before effecting the bond to insure that the particular wire(s) is bonded to the correct contact(s), for example, to insure that wire 3, and not wire 4, is bonded to contact 5'.

Color Detection System

The bonding of the ends 1, 2 of an insulated twisted pair of wires 3, 4, having respective insulations R, G of different colors, e.g., red and green, often requires that at least one of the wires be in a proper orientation before effecting the bond to insure that the particular wire(s) is bonded to the correct contact(s), for example, to insure that wire 3, and not wire 4, is bonded to contact 5'.

In the present system a closed color TV system 10 is used to monitor the orientation of the colored wire 3 prior to effecting the bond. More particularly, TV camera 11 scans an enlarged image provided by objective lens 12 of the ends 1,
2. The video signal is fed to the cathode-ray tube (CRT) receiver 13 for viewing of the televised image. Color signals that are developed in receiver 13 are also fed to comparison and detection circuit 14. In the latter, gating signals are generated in synchronization with the scanning signal which sequentially gate the individual color comparison stages at the expected, i.e., desired, times of their appearance in the horizontal scan, these times being thus correlated with the space coordinates of the viewing frame.

If the correct color wire is not detected at the desired spatial position, the detector generates a control and inhibit signal BOND which prevents the bonding of the wire 3 until it is properly oriented with respect to contact 5'. When the correct color wire is detected at the desired position, it gener...
