Description

The present invention relates to a winding device for automatically winding a deflection yoke for deflecting an electron beam of a cathode ray tube.

(Prior Art) Conventionally, as this type of device, as in Japanese Patent Publication No. Sho 49-23050, a wire rod feed head that moves vertically is used, and the frame of the deflection yoke is slidable in a horizontal plane. It has been proposed to rotatably support and perform the automatic winding of the deflection yoke by combining the vertical movement of the wire feed head, the slide movement of the deflection yoke frame, and the rotation movement of the deflection yoke frame.

(Problems to be solved by the invention) However, in the device of Japanese Patent Publication No. Sho 49-23050, both the wire rod feed head and the deflection yoke have to perform reciprocating linear motion, which makes it difficult to perform high-speed winding. . Further, since the automatic winding is possible, the shape of the frame (winding frame) of the deflection yoke is also limited.

(Means for Solving the Problems) In view of the above points, the present invention enables high-speed automatic winding of the deflection yoke by utilizing the rotational movement of the rotor for guiding the wire and the frame of the deflection yoke, Moreover, it is an object of the present invention to provide a highly reliable deflection yoke winding device in which the wire is reliably guided by the fixed winding guide to the vertical slot of the deflection yoke.

The present invention has a large number of vertical slots at predetermined angular intervals on the inner surface of a substantially cylindrical frame, and annular channels on the outer surfaces of the upper and lower ends, the annular channels having grooves at positions corresponding to the vertical slots. A deflection yoke winding device that winds around a deflection yoke that has a support mechanism that rotatably supports the deflection yoke, and a plurality of rollers that guide the wire rod, and a position that penetrates the substantially cylindrical frame. An annular rotor rotatably supported by a device frame, and the longitudinal rotor that is closely opposed to each other along the convex portions on both edges of the longitudinal slot in which the wire is guided by the rotation of the rotor. A fixed winding guide having a guide surface that matches the inner surface of the directional slot and fixed to the device frame side is provided to prevent the wire rod from accidentally entering the adjacent slot. By guiding the to solve the problems of the prior art, it is realized further improvement of reliability.

(Operation) In the winding device of the deflection yoke of the present invention, the wire rod can be guided to the vertical slot of the deflection yoke by the rotation operation of the rotor, and the wire rod can be moved in the horizontal direction by the rotation operation of the tubular frame of the deflection yoke. Wires can be guided along the annular channel and into adjacent longitudinal slots or other pairs of longitudinal slots. Therefore, all winding operations can be performed by a combination of rotary motions, and the winding work can be speeded up. Further, the fixed winding guides can be closely opposed to each other along the convex portions on both edges of the vertical slot to prevent the wire from accidentally entering the adjacent slot when the wire is guided to the vertical slot. The reliability of the operation can be improved. Further, the structure of the device may be simple.

On the other hand, the frame (winding frame) 10 of the deflection yoke has a substantially cylindrical shape, has a large number of vertical slots 11 at predetermined angular intervals α on its inner surface, and has annular channels 12 and 13 on its upper and lower outer surfaces. The annular channels 12, 13 have a groove at a position corresponding to the longitudinal slot 11. The frame 10 of such a deflection yoke is supported by the support mechanism 14 so as to be intermittently rotatable at the arrangement angle interval α of the vertical slots 11. Also,
The support mechanism 14 has a structure in which the frame 10 can be attached and detached for replacement.

As shown in FIGS. 2 and 3, the rotor 1 has rollers R1 to R5 that circumscribe and guide the wire rod.

Set R3 in the range of 220 ° to 260 ° clockwise with R1 as the reference. The roller R2 is close to R1.

A roller R6 is pivotally supported on the apparatus frame 2 side at the positions shown in FIGS.

In addition, the vertical slots of the deflection yoke frame 10
In order to increase the reliability of winding the wire around the fixed wire 11, the fixed winding guide 25 is arranged so as to closely face the projections 26 on both edges of the longitudinal slot 11 as shown in FIGS. 1 and 4. . That is, the fixed winding guide 25 closely opposes the convex portions 26 on both edges of the vertical slot 11 which are curved along the up-down direction of the inner surface of the cylindrical frame 10 and into which the wire is guided. And each has a guide surface 25a corresponding to both inner side surfaces 11a of the vertical slot. Further, the lower end of the fixed winding guide 25 is extended and fixed to the device frame side.

(Effects of the Invention) As described above, according to the winding device for the deflection yoke of the present invention, the rotor is provided so as to penetrate the tubular frame of the deflection yoke, and the inner surface of the tubular frame is rotated by the rotation of the rotor. Since the wire rod is guided to the longitudinal slot, all the winding operations can be performed by a combination of rotary motions, and the winding work can be speeded up (for example, 10 times or more as compared with the conventional device). Further, by providing the fixed winding guide, the winding of the wire into the vertical slot of the deflection yoke frame can be performed with high reliability. Further, the structure of the device is simple, and there are advantages that it can be applied to various deflection yoke frame shapes.
