Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a saddle type deflection coil winding device used for a deflection yoke.

[0002]

A winding device for forming a saddle type deflection coil by winding a coil winding is disclosed in Japanese Patent Laid-Open No. 63-1163.
No. 33. When a saddle type deflection coil is formed using this apparatus, as shown in FIG.
The coil winding 1 of the book is paid out from the nozzle (wire guide tube) 2, and the nozzle 2 is moved from the position a of the crossover part 3 on the tail side to the position e through the positions b, c, d in the direction of the arrow,
In this state, the coil body 4 is rotated clockwise by 180 ° to form the crossover portion 5 on the head side, and then the nozzle 2 is moved upward, and then the coil body 4 is rotated leftward by 180 °. The nozzle 2 is set to the position f of FIG. 8B, and in this state, the nozzle 2 is moved downward along the groove inside the coil body 4, then moved from the position g to the position h, And coil body 4 180 °
Rotate to the left to wind the crossover portion 3 on the tail side, move the nozzle 2 to the right until it reaches the i position, and
The saddle-type deflection coil is wound and formed by returning to the first position a and repeating the movement of the nozzle 2 and the rotation of the coil body 4.

[0003]

However, in the conventional winding device, one or several single wire coil windings 1 are unwound from the nozzle 2 and wound into a groove sufficiently wider than the wire diameter. Therefore, when the coil winding is repeatedly wound along the groove, the coil winding is wound with the line shifted toward one side of the groove, so that the distribution of the deflection magnetic field of the saddle-type deflection coil varies. However, there is a problem that it is not possible to meet the demand for higher definition and larger screens of television receivers and display devices.

In order to solve such a problem, the inventor of the present invention has proposed a method of winding a multi-core parallel conductor wire such as a ribbon wire in a groove of a die or a bobbin. According to this method, a groove of a bobbin or a die is formed in a groove having almost the same width as the multicore parallel conductor wire, and the multicore parallel conductor wire is wound in the groove, whereby the coil winding is displaced in the groove and is offset. It is possible to precisely control the deflection magnetic field of the saddle type deflection coil and sufficiently meet the demands for high definition of the television screen and the like.

However, when a multi-core parallel conductor is wound using the conventional winding device, for example, as shown in FIG. 8A, it is wound upward along the groove inside the coil body 4, and then And d
Since it is not possible to rotate or adjust the angle of the nozzle 2 when moving from the position of to the position of e and moving to the winding of the crossover wire portion 3 or when winding from the crossover wire portion to the next groove, the multi-core parallel conductor wire Is twisted and corrugated, and the multi-conductor parallel conductor cannot be neatly wound along the groove of the coil body 4, and there is a problem in that the advantage of using the coil winding as the multi-conductor parallel conductor cannot be utilized.

The present invention has been made to solve the above problems, and an object of the present invention is to make a saddle-type deflection coil by winding a multicore parallel conductor wire without twisting or waviness. To provide a winding device for a type deflection coil.

[0007]

In order to achieve the above object, the present invention is configured as follows. That is, in the winding device of the present invention, the device base is provided with a frame-shaped holding portion for holding a winding frame mold around which the multi-core parallel conductive wire is wound, and a nozzle for supplying the multi-core parallel conductive wire to the winding frame and winding the same. The frame die holding part has a reciprocating movement in the central axis direction (Z-axis direction) of the reel die with respect to the reel die, and a rotational movement about the central axis (Z axis). A reel-type drive mechanism that performs rotational movement about an axis in a direction (X-axis direction) orthogonal to the central axis is linked, and the nozzle is connected to the central axis (Z direction). ) And a movement (Y direction) orthogonal to a plane (Z-X plane) in a direction (X direction) orthogonal thereto and a rotation movement about an axis in the movement direction (Y direction). , Nozzle drive machine for performing variable angle movement of the sent multi-core parallel conductor wire in the width direction and forward / backward movement in the X-axis direction There is configured as characterized in that it is linked.

[0008]

In the present invention having the above-mentioned structure, when the multi-core parallel conductor is supplied from the nozzle to wind the multi-core parallel conductor on the winding frame type, for example, the nozzle is positioned on the inner peripheral surface of the lower end of the winding type, By moving the winding frame die downward in the Z-axis direction (for example, the vertical direction), the multicore parallel conductor wire is wound around the groove on the inner peripheral surface of the winding frame die from the lower end to the upper end. The nozzle is rotated (revolves) around the Y-axis from the inner peripheral surface position of the upper end side of the winding form while adjusting the angle to move to the outside of the upper end of the winding form. For example, enter the groove on the crossover part side of the head side from the inner peripheral surface, and in this state, rotate the reel form 90 ° around the X axis, and then rotate the reel form 180 ° around the Z axis. By doing so, the multi-core parallel conductor wire is wound along the connecting wire portion on the head side. As described above, when the crossover portion is wound, the angle of the nozzle is variably adjusted, so that the multi-conductor parallel conductor wire is wound normally along the groove of the crossover portion without twisting or waviness. In this way, the reel type Z
Axial movement, rotational movement around the X-axis and Z-axis of the reel frame, forward / backward movement of the nozzle in the Y direction, rotational (revolution) movement about the Y-direction axis, and variable angle adjustment movement. By performing the advancing / retreating movement in the X-axis direction at a predetermined timing, the multi-core parallel conductor wire is correctly wound around the winding frame type to form a saddle type deflection coil.

The rotational movement and the rotational movement centered on the X axis orthogonal to the Z axis on the plane are possible, and the nozzle side for feeding the multi-core parallel conductors to the winding frame is set to the ZX plane. It is configured such that it can be moved forward and backward in the Y direction orthogonal to each other, rotationally moved about the Y axis, angle adjustment in the width direction of the multi-core parallel conductor to be sent out, and forward and backward movement in the X axis direction. Therefore, after winding the multi-core parallel conductor wire in the Z direction along the peripheral surface of the winding frame type and when winding it on the crossover part, the angle of the nozzle is variably adjusted and an unreasonable force is applied to the multi-core parallel conductor wire. Since it can be wound so that it does not hang, the multi-core parallel conductor wound around the crossover part etc. may be twisted or corrugated. Without, it is possible to clean the wound.
