The present disclosure generally relates to wire kitting and, more particularly, to automated wire kitting systems and methods.
Wire or cable kitting is the process of obtaining a wire, stripping away a portion of the wire's insulation, and crimping a terminal onto the exposed portion of the wire to form a wire lead.

Further areas of applicability of the present disclosure will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the disclosure.
The present disclosure will become more fully understood from the detailed description and the accompanying drawings, wherein:
As discussed above, a wired connector or wire harness typically comprises a plurality of wire leads having their terminals inserted into and secured within respective terminal portions of a connector. During assembly of wired connectors, a human or robotic assembler typically follows a set of instructions (a wire diagram, computer-executable instructions, etc.) whereby a container or bin of wire leads is searched through to identify a target wire lead, which is then installed by the assembler into a respective target terminal portion of a connector. This process can be costly and time consuming and can also result in a large number of wire leads or wired connectors not passing testing, leading to decreased first time quality (FTQ) metrics and increased costs to fix improperly assembled wire leads and/or wired connectors. Thus, while these conventional assembly systems and methods work well for their intended purpose, an opportunity exists for improvement in the relevant art. Accordingly, improved wire lead and wired connector assembly systems and methods are presented herein.
These systems and methods utilize an automated wire kitting system that robotically prepares wires and terminals and crimp presses terminals onto respective wires. The assembled wire leads are then provided to a wire lead singulation system, which can be delivered to a wired connector assembly station where a human or robotic installer can follow a specific set of instructions (e.g., left-to-right along a pallet) to quickly and accurately assembly the wired connector. The terminal preparation and singulation allows for multiple different types of terminals (e.g., eight) to be singulated and delivered to the crimp press. The crimp press also includes a shuttle system comprising a plurality of different dies (e.g., eight) such that the different types of terminals can be properly crimped onto the prepared wires. A removable wedge feature supports the crimp press during crimping while also allowing for changing of the engaged die. These improved systems and methods can increase FTQ metrics and decreasing costs to fix improperly assembled wired connectors. In addition, less extensive training/knowledge by human assemblers is required, which could further decrease costs and provide for more task flexibility at an assembly plant or facility.

By being able to use a single load sensor 520 for all of the plurality of dies 504, costs can be reduced (e.g., compared to needing separate, permanent load sensors 520 for each of the plurality of dies 504. Each assembled wire lead 100 is then fed by the wire gripping members 400 and the drive system 404 to the wire lead singulation system 524.
