[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an apparatus and a method for manufacturing a small coil wound around a chip-type core, for example.

[0002]

2. Description of the Related Art
In the coil winding machine, one of the workpieces is held by a chuck, and the wire is wound around the workpiece by a flyer. Therefore, when the work becomes small, the chuck becomes unstable, and when the chuck force is weak, the work tilts during winding,
There was a fall.

Also, a transfer device is required to transfer the work from the parts feeder to the chuck. However, since the work is sandwiched and transferred to the chuck, if the work is small, chuck errors easily occur. There was a problem of poor sex.

In the index type (for example, see Japanese Patent No. 2957947), this chuck type winding machine uses a fusing unit arranged at another index position after winding to fuse a wire to an electrode. In the meantime, it is necessary to index the wire while the wire is crawling on the electrode. Therefore, it is necessary to guide the wire so that the position of the wire on the electrode does not change during the indexing.

On the other hand, there is a type of holding both sides of a work and winding a wire around the work by rotation of the work (for example, see Japanese Patent No. 2957947). In this case, a driving force for transmitting a rotational driving force to both sides of the work is provided. Since the transmission mechanism is provided, when the nozzle unit, the clamper, the heater chip, and the moving mechanism thereof are disposed, there is a problem that the apparatus becomes large and it is difficult to dispose the apparatus.

Further, the position and the direction of welding of the wire to the electrode cannot be changed, and the versatility is lacking. Further, there is a problem that the method cannot be applied to a bifilar winding in which a plurality of wires are wound in parallel.

An object of the present invention is to provide a coil manufacturing apparatus and a manufacturing method which solve such problems.
