Abstract
In order to wind a coil on a bobbin, the bobbin is supported on a rotating unit. Wire, which is supplied to a nozzle, is first clamped by a clamp which is synchronously rotatable with the bobbin. The nozzle is then moved along two mutually perpendicular axes so as to, in combination with the rotational movement of the bobbin, permit a coil or coils to be wound on the bobbin. After the wire is wound onto the bobbin, the wire is clamped and cut by a clamping and cutting arrangement which is stationary with respect to the bobbin rotation.
Claims7
A coil winding device comprising:
- a bobbin rotating unit for holding and rotating a bobbin upon which a wire is to be wound;
- a nozzle for feeding wire onto said bobbin;
- wire clamp means for clamping a first portion of the wire fed out of said nozzle, said wire clamp means being rotated synchronously with said bobbin rotating unit;
- cutting means for clamping and cutting a second portion of the wire which has been fed out of said nozzle and wound onto said bobbin;
- and
- control means for controlling of selective motion of said nozzle in a vertical direction substantially at a right angle to a horizontal direction in parallel with an axis of said bobbin, controlling a rotation of said bobbin rotating unit, controlling a clamp of said wire with said wire clamp means and controlling the clamp and cutting of said wire with said cutting means.
A coil winding method comprising the steps of:
- continuously controlling a rotation of a bobbin rotating unit which rotates a bobbin onto which a wire is wound, using a control means,
- feeding wire out through a nozzle,
- clamping a first portion of wire fed out of the nozzle using clamping and means and rotating the clamping means with the bobbin rotating unit, and
- clamping and cutting a second portion of the wire after the wire has been wound on said bobbin using clamping and cutting means.
A coil winding method comprising the steps of:
- rotating a bobbin in a predetermined manner;
- feeding wire out through a nozzle;
- clamping a first portion of the wire from the nozzle using a clamp which rotates synchronously with the bobbin;
- moving the nozzle in at least two mutually opposed linear directions so as to, in combination with the rotational movement of the bobbin, wind a coil having a predetermined configuration on the bobbin;
- and
- clamping and cutting a second portion of the wire after the wire has been wound on said bobbin, using stationary cutting and clamping means.
A coil winding apparatus comprising:
- means for rotating a bobbin in a predetermined manner;
- means for feeding wire out through a nozzle;
- means for clamping a first portion of the wire from the nozzle using a clamp which rotates synchronously with the bobbin;
- means for moving the nozzle in at least two mutually opposed linear directions so as to, in combination with the rotational movement of the bobbin, wind a coil having a predetermined configuration on the bobbin;
- and
- means for clamping and cutting a second portion of the wire after the wire has been wound on said bobbin, said clamping and cutting means being stationary with respect to the rotating bobbin.
