Wirewound device

Abstract

To improve accuracy of the shape and characteristics of a coil (a deflection yoke) by accurately guide a wire to the specified winding position of a spool. A nozzle supporting part for supporting a nozzle is rotatably pin-connected to the tip of a wire supplying device capable of being freely moved in the three dimensional direction by a moving device, an engaging member to be freely turned in the normal state and to be engaged with a gear provided on the base end of the nozzle supporting part is provided, and the turning angle of the nozzle supporting part can be fixed. In winding work near a small-diameter opening part of a spool, plate members are rotatably turned to be entered into both sides of a hook of a lower hook device on which a wire is to be hooked and guided, and the wire is pushed out by the plate members to be turned, when the wire is released from the hook.

Description

technical field [0001] The present invention relates to a deflection yoke winding device, and more particularly to an improvement in that the wire can be correctly guided to a prescribed winding position of a bobbin. Background technique [0002] Winding devices for manufacturing deflection yokes are disclosed in JP-A-6-325963, JP-A-7-220636, and JP-A-5-258669. [0003] These winding devices are the wire from the Figure 18 The freely movable nozzles not shown are drawn out. wrap it around like Figure 18 As shown, the deflection yoke is formed on a funnel-shaped (horn-shaped) coil frame (deflection coil frame) 1 with a large-diameter opening 2 and a small-diameter opening 3 respectively up and down. At this time, this can be freely moved. The nozzle is introduced from the large-diameter opening 2 and lowered to pass through the small-diameter opening 3. With this action, the wire drawn from the above-mentioned movable nozzle is cut longitudinally along the inner circumfere...

Problems solved by technology

[0007] However, in the existing winding device, during the winding operation, the wire drawing end of the nozzle is fixed at a certain angle, so for example, when the nozzle is lowered with the wire drawing end facing down, the wire needs to be drawn from the wire. The pull-out end is pulled out with a roughly 180-degree bend, which will increase the friction between the wire and the nozzle, so the tension on the wire will also increase

In addition, in the existing winding device, the tension applied to the wire also changes depending on the winding position, which also causes the shape and characteristics of the deflection yoke to be unstable
