The present invention relates to a deflection coil winding machine, and more particularly, to a saddle of a dark winding type so as to apply air for cooling immediately after winding a coil having ductility into a roughly saddle shape through the driving of a male winding and a female winding. The present invention relates to a deflection coil winding machine configured to pass through a plurality of air outlets and to simultaneously discharge the air by communicating with the air outlets and an air injector.

In general, a deflection coil is divided into a horizontal deflection coil and a vertical deflection coil 10. A deflection yoke for realizing an image by deflecting a direction in which image quality requests an electron beam emitted from a cathode ray tube of a television is horizontal. A deflecting horizontal deflection coil (not shown) is wound and mounted on the inner circumference of the separator 20, and is mounted on the outer circumference to form a vertical deflection coil 10 for deflecting the electron beam in the vertical direction.

At this time, the vertical deflection coil 10 is mounted in a shape seated on the outer periphery of the separator 20 formed in a substantially trumpet shape, as shown in the perspective view of Figure 1, not shown on the outer periphery of the separator 20 The horizontal deflection coil is mounted in a shape to be seated.

At this time, the deflection coil for horizontal deflection and vertical deflection of the traveling direction of the electron beam is formed by winding a plurality of times in a substantially saddle shape to be seated on the inner and outer circumferences of the separator 20. On the surface of the deflection coil, an insulating coating made of enamel or the like is coated.

Such an insulation coating generates an adhesive force at a predetermined temperature of about 38 ° C. ± 1, and enables the saddle-shaped deflection coil to be maintained using this adhesive force.

Referring to FIG. 2, a deflection coil winding machine according to the related art for forming the saddle-shaped deflection coil is as follows.

2 is a schematic view showing a deflection coil winding machine according to the prior art.

As shown in FIG. 2, the deflection coil winding machine 100 according to the related art has a male winding 110 and a female winding 120 for winding out coils wound on bobbins and winding-molding them into a saddle-shaped deflection coil. It consists of a support box 130 for supporting the male winding 110 and the female winding 120.

At this time, the support box 130 is a support body 131 having a substantially rectangular cylindrical shape to protect the male winding 110 and the female winding 120 built-in, and a cover body covering an upper portion of the support 131 ( 132, the male winding type 110 is a male disk member 111, which is embedded in the support 131 and rotates, and a male winding type saddle 112 assembled to the male disk member (111). The arm winding 120 is composed of a female disc member 121 that is rotated by an external power source, and a female winding 122 that is assembled to the female disc member 121.

At this time, the male winding 110 and the female winding 120 is rotated clockwise and counterclockwise by an external power source to wind the coil supplied through the coil bobbin into a saddle shape to obtain a desired deflection coil. It becomes possible.                         

On the other hand, the coil winding is performed while maintaining the normal convergence characteristics only when the ambient temperature of the deflection coil is maintained at approximately 38 ℃ ± 1, if the convergence characteristics during operation of the winding type 110 and female winding 120 In this case, the winding type 110 and the female winding 120 are stopped, and when the stopping time becomes longer, the winding temperature is cooled, and the convergence characteristic becomes XH under, so that the winding is returned to the original normal temperature. As it takes 40-60 minutes to maintain, the failure rate is often generated.

Therefore, the winding operation of the coil in the cover body 132 located above the male winding 110 and the female winding 120 so as to maintain the ambient temperature of 38 ° C. ± 1 during winding of the deflection coil. The heater 140 is installed to be driven together to maintain a proper temperature.

By the way, the deflection coil winding machine 100 according to the prior art can easily form the winding of the saddle-shaped deflection coil by installing a heater to maintain the ambient temperature at a temperature of 38 ℃ ± 1 when the coil is wound. However, insulation coatings such as enamel coated on the outer circumference of the coil surface must be cooled again to a low temperature so that they can solidify and bond to each other and have a solid supporting force. The work takes too much time, and the mutual adhesion is poor, so the reliability of the product is greatly reduced.

The present invention has been made in order to solve the above problems, and its object is to wound the coil having ductility in the state heated by the heater to approximately saddle shape through the drive of the male and female winding type Insulation coatings such as enamel coated on the outer circumference of the coil surface are coagulated and mutually solidified so that air is supplied to the deflection coil through an air inlet and an air outlet formed inside the dark winding type for cooling to ensure a firm supporting force. It is to provide a deflection coil winding machine that can maximize the mutual adhesion.

The present invention for achieving the above object, a deflection coil winding machine comprising a male winding and a female winding consisting of a male rod member and a female winding saddle assembled to at least a male disc member and a female disc member rotated by an external power source In the winding of the deflection coil, an insulation coating such as enamel coated on the outer periphery of the coil surface is coagulated and bonded to each other to form an air injector inside the dark wound saddle to cool to have a solid support force, and injects air therein. The air supplied from the air injector is provided with an air outlet for penetrating through the dark winding saddle and branched out into various parts.

Hereinafter, a preferred embodiment of the deflection coil winding machine according to the present invention will be described with reference to FIG. 3.

It consists of a support box 130 for supporting the male winding 110 and the female winding 120.

In this case, the support box 130 is a support body 131 of a substantially rectangular cylindrical shape to protect the male winding 110 and the female winding 120 built-in, and a cover body covering an upper portion of the support 131 ( 132).

On the other hand, in order to maintain the ambient temperature of the deflection coil approximately 38 ℃ ± 1, the cover body 132 is provided with a heater 140 to be driven together during the winding operation of the coil to maintain a proper temperature.

In addition, a plurality of air outlet 122a is formed through the dark wound saddle 122, and the saddle-shaped deflection is substantially driven through the driving of the male winding 110 and the female winding 120 in the air outlet 122a. After the coil is wound, the air is injected into the air outlet 122a which is in communication with the air injector 150 which applies cooling air to closely solidify and adhere to each other.

Referring to the operation and action of the deflection coil winding machine 100 of the present invention made of the above configuration as follows.

After winding the coil having ductility in the heated state by the heater 140 to the saddle shape through the driving of the male winding 110 and the female winding 120, the relative coil relative to the deflection coil forming the saddle shape. By cooling with the addition of low temperature air, it coagulates together and completes the winding of the deflection coil.

Here, the air injector 150 that applies relatively low temperature air is driven at the time when the driving of the heater 140 is completed so that it can be directly applied to the coil through the air outlet 122a so that the mutual adhesion of the deflection coils It can be seen that the action to increase the time and shorten the time of the winding process.

As described above, according to the deflection coil winding machine according to the present invention, a coil having a ductility in a heated state by a heater is wound in a roughly saddle shape by driving a male winding and a female winding, and then cooled with relatively low temperature air. By forming a plurality of air outlets through the dark winding saddle to communicate with the air inlet to the air outlets, it is possible to maximize the adhesion between the coils during the winding of the deflection coil and to reduce the time of the winding process. It can provide an excellent effect on the improvement of productivity due to the increase of working efficiency.
