Abstract
An apparatus for winding a wire onto a one-piece deflection yoke frame is such that the wire is fed from a winding supply source to a nozzle unit. A guide mechanism for holding the wire from the nozzle unit draws the wire to a work piece which is disposed on a work receiving base. The wire is then clamped by a wire clamp and wound onto the work piece by a predetermined sequence of movements of the nozzle unit, the guide mechanism and rotation of the work receiving base.
Claims20
A winding apparatus for winding a wire fed from a winding feeding source onto a work piece, comprising:
- a work receiving base on which the work piece is supported;
- a nozzle unit to which the wire is fed from the winding feeding source, said nozzle being operatively connected with servo means for moving said nozzle up and down with respect to said work receiving base;
- a guide mechanism which is movable toward and away from said work receiving base for grasping the wire from said nozzle unit and for drawing the wire to the work piece supported on said work receiving base;
- a wire clamp for clamping the wire that has been guided by said guide mechanism to the work piece;
- and
- rotary means for rotating the work receiving base,
- wherein after the wire has been clamped by said wire clamp, the wire is wound on the work piece by vertical movement of said nozzle unit, a holding operation of said guide mechanism and a rotational operation of said rotary means.
A winding method for winding a wire fed from a winding feeding source to a work piece in a winding apparatus, said apparatus comprising:
- a work receiving base on which the work piece is supported;
- a nozzle unit to which the wire is fed from the winding feeding source, said nozzle being operatively connected with servo means for moving said nozzle up and down with respect to said work receiving base;
- and
- a guide mechanism which is movable toward and away from said work receiving base for grasping the wire from said nozzle unit and for guiding the wire to the work piece supported on said work receiving base;
- a wire clamp for clamping the wire that has been guided by said guide mechanism to the work piece;
- and
- rotatory means for rotating the work receiving base,
- said winding method comprising the the steps of:
- clamping the wire by said wire clamp;
- and
- after said clamping, winding the wire onto the work piece using a movement of said nozzle unit, a holding operation of guide mechanism and a rotational operation of said rotary means.
