Abstract
A process for mass production of electronic components includes the steps of gripping the output and input wires extending from a wire core as mounting plates which carry the cores pass over a winding head which distributes wire to each core. The wire is gripped by an operable holding device located a predetermined distance from the wire cores to provide a sufficient free length of the wires to bring the wires into a position readily available for a following operation.
Claims4
A process for mass production of electronic components comprising the steps of:
- providing a plurality of cores projecting from a plurality of mounting plates;
- providing a winding head for sequentially winding a wire around each of said plurality of cores, said winding head including at least one rotatable arm for guiding a wire from a supply reel around each said core;
- holding a portion of a wire extending from said arm with a first holding device, the holding device located adjacent a first core of said plurality of cores, such that a wire free end extends from the first holding device;
- relatively moving said winding head and said first core to a winding position where said winding head is aligned with said first core such that wire is pulled from said winding head arm in a taut condition between said first holding device and said first core;
- operating said winding head to form a coil winding on said first core;
- relatively moving said winding head and said first core to a second winding position where said winding head is aligned with a second core of said plurality of cores such that wire is pulled from said winding head in a taut condition from said first core to said second core, said wire extending from the first core to the second core including an output wire portion extending from the first core and an input wire portion extending from the output wire portion to the second core;
- holding a portion of the output wire portion in a second holding device to maintain a taut output wire reserve portion between the second holding device and the first core;
- holding a portion of the input wire portion in a third holding device to maintain a taut input wire reserve between the third holding device and the second core;
- and
- cutting the wire between the second and third holding devices to create an output wire reserve free end extending freely from the second holding device, and an input wire free end extending freely from the third holding device.
