Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device for winding a wire on a work, and more particularly to a winding device for winding a wire around a frame of a deflection yoke to obtain a saddle type coil or the like.

[0002]

2. Description of the Related Art Two or more work terminals for applying a voltage are provided in parallel and close to each other on a side surface of a frame body of a deflection yoke. When the wire rod is wound around the frame body of the deflection yoke, it is necessary to entangle the wire rod with these work terminals. Conventionally, for example, the nozzle unit 4 shown in FIG.
3 and the upper and lower guide units 53 and 54 are used to bind the work terminal with the wire.

[0003]

In the above-mentioned conventional binding of the wire material to the work terminal, the upper and lower guide units must be rotated around the axial center of the work terminal. Therefore, when the distance between the work terminals is small, there is a problem that it may be difficult to perform the binding operation.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a winding device capable of easily tying a wire rod around a work terminal of a work.

[0005]

According to the present invention, there is provided a winding device for winding a wire on a work,
This is achieved by providing a shaft for entwining the wire rod with the terminal of the work, and a drive unit for rotating the shaft to entangle the wire rod with the terminal of the work.

According to the above construction, since the wire rod is entangled with the work terminal by the shaft that rotates coaxially with the work terminal, the entanglement operation can be easily performed in a narrow space.

It is rotatable via a belt 68 hung between 67c. Then, each spindle 61a, 61b,
61c can be moved and positioned in the arrow Y direction by the operation of the actuator 69.

FIG. 3 is a perspective view showing the details of the spindle 61a. The spindle 61a has a core 612 having a forming head 611 for winding the wire W at one end.
And a socket 613 which houses the other end of the core 612 and rotates together. The core 612 is the socket 6
It is pressed by a compression spring 614 inserted in the shaft 13. At the tip of the forming head 611, an edge portion 611a that first entangles the wire W, a curved portion 611b that guides the wire W entangled by the edge portion 611a, and the tip of the curved portion 611b and the core 612. An inner guide groove 611c that engages with the tapered portion 612a of the portion and introduces the wire W is formed. The inner guide groove 611 is formed on the outer peripheral portion of the forming head 611.
The outer guide groove 611d is formed in a spiral shape so as to be continuous with c. It is desirable that the width and depth of the outer guide groove 611d be 1.3 to 1.75 times and 0.4 to 0.5 times the outer diameter of the wire W, for example. Moreover, it is desirable that the cross-sectional shape be, for example, a semicircle or a square. The other spindles 61b and 61c have the same structure.

A method of entwining the wire W with the work terminal 1 provided on the side surface of the work K in such a structure will be described with reference to FIG. 4 by taking the spindle 61a as an example. First, the actuator 69 is driven to move the spindle 61a in the direction of the arrow Y to approach the work K, and the work terminal 1 is introduced from the tip of the core 612 into the core 612. Next, the driving unit 64 is driven to rotate the spindle 61 a, and the wire W pre-tensioned in the vertical direction between the nozzle unit 43 and the work K and near the work terminal 1 is attached to the forming head 611. Entanglement by the edge part 611a. The curved portion 611b of the forming head 611 and the taper portion 612a at the tip of the core 612.
The wire W entangled with the forming head 61
It is introduced into the first inner guide groove 611c and subsequently wound around the outer guide groove 611d.

Further, while driving the drive unit 64 to rotate the spindle 61a, the actuator 69 is driven to move the spindle 61a in the direction of the arrow Y to move away from the work K, and the wire W is deformed by the outer guide groove 611d. While straightening, the wire W is entwined from the root of the work terminal 1 in an aligned manner. At this time, since the core 612 is pressed by the compression spring 614 inserted in the socket 613, the forming head 611 is gradually moved away from the work terminal 1. As a result, as shown in FIG.
Wires W are wound in an array as shown in FIG.

Incidentally, by gradually roughening the pitch of the outer guide grooves 611d from the tip of the forming head 611, the habit of the wire W is gradually removed, so that the work terminal 1 can be smoothly entangled and finished. Since the state is also improved, it is possible to smoothly perform the two-layer entanglement in which the wire rods W are entwined and entangled.
