Description

Enameled wire twisting apparatus for balun transformer maker

The present invention relates to a balun transformer manufacturing machine, and more particularly, to an enamel wire braiding device of a balun transformer transformer twisting two strands of the enamel wire inserted into the core.

Balun transformers are used for frequency conversion or frequency filtration of various tuners used in electronic devices such as TVs and VTRs. The balun transformer is manufactured by winding two enameled wires through the core, twisting one end of each enameled wire, and cutting a predetermined length to form a total of three leads.

The production of these balun transformers has been done by hand. First, the worker inserts the enamel wire into the core and twists one end of the inserted enamel wire with each other. Next, the length of the ends of the twisted enamel wire and the other enamel wire is cut to form a lead, and the lead is buried to complete the production of the balun transformer.

However, the production of the balun transformer by hand has a problem that the productivity is lowered, leading to the production of an automated balun transformer maker. In such an automated balun transformer manufacturing machine, there are the following problems in the configuration for twisting a relatively long end of two enameled wires which are bent and inserted into a 'U' shape in a core.

First, the end of the enamel wire is held by the chuck is rotated twisting operation, the gear for the rotation of the chuck corresponding to each core is engaged with the gear for rotating the chuck for twisting the adjacent core is transmitted power.

Therefore, the degree of rotation varies between the chuck driven by the first gear that receives the power transmitted from the drive source and the chuck driven by the last gear transmitted for the smooth driving of the gear. For example, if the first gear that received power is exactly six turns, the last gear is not exactly six turns. Therefore, the enameled wire twisted by the chuck driven by the last gear is not twisted a predetermined number of times, resulting in a defect.

In the related art, when the chuck catches the enamel wire, the enamel wire should be in close contact with the surfaces of the fingers corresponding to each other. However, the enamel wire cannot be reliably held in a circular cross section, so that the twisting operation is not properly performed. .

Accordingly, an object of the present invention is to solve the problems of the prior art as described above, and to provide an enamel wire braiding device capable of simultaneously simultaneously twisting each enamel wire provided in a plurality of cores.

Another object of the present invention is to provide an enamel wire braiding device in which the enamel wire is more firmly gripped.

Let it open and fall.

That is, when the finger driving rod 77 is raised, the tips of the fingers 74 are opened to each other, and when the finger driving rod 77 is lowered, the tips of the fingers 74 are lifted to hold the gripping irons 76 and 76. ') Are combined with each other.

The lower end of the finger driving rod 77 is provided with a restoring spring (79). One end of the restoring spring 79 is supported by a support washer 79b installed at the finger driving rod 77, and the other end is supported by a support washer 76t provided at the rotation shaft 53 side. The restoring spring 79 provides an elastic force that allows the tips of the fingers 74 to be coupled to each other.

Hereinafter will be described in detail the operation of the enamel wire braiding device of the balun transformer production machine according to the present invention having the configuration as described above.

In the enamel wire inserting device (D), the enamel wire 13 is inserted into the core 12, and the core 12 is transferred along the transfer rail 15. When the core 12 is transmitted to the transfer rail 15 at a position corresponding to the enamel wire braiding device E in the transfer rail 15, the enamel wire braiding device E is operated.

First, the state of FIG. 7A is an initial state, in which the first transfer base 26 is moved to the right with respect to the drawing, and thus the chuck 70 is retracted from the lower portion of the transfer rail 15. to be. This is to prevent interference with the carrier (not shown) of the co-eye feeding device (B).

In this state, the chuck driving plate 67 does not support the finger driving rod 77 so that the front ends of both fingers 74 are coupled to each other by the elastic force of the restoring spring 79. The spring guide 38 provided at the tip of the driving rod 37 of the elevating driving source 36 maintains the state supported by the first transfer base 26.

Next, as shown in Figure 7b, the chuck drive source 60 is operated. When the driving rod 61 of the chuck drive source 60 raises the elevating connecting plate 63, the elevating driving rod 65 is guided and raised by the bearing 66, and the lower end of the elevating driving rod 65. The chuck drive plate 67 provided in the push up the finger drive rod (77).

When the finger driving rod 77 is raised, the interlocking pin 78 of the upper end of the finger driving rod 77 is raised along the linking slot 73, and at the same time is guided along the driving slot 75 and the finger ( Let the tip of 74) open.

At the same time as the tip of the finger 74 is opened or opened, the first transfer base 26 is transferred in the right direction as shown in FIG. 7C by driving the transfer drive source 21. . That is, as the driving rod 22 protrudes from the transfer driving source 21, the transfer bearing 26 ′ is moved along the transfer guide rod 24.

When the first transfer base 26 is transported as described above, the second transfer base 30 provided in the first transfer base 26, various configurations provided in the second transfer base 30, the lifting drive source 36, the drive motor 40, the chuck drive source 60, the chuck 70 and the like are moved together. In particular, the chuck 70 is moved to be positioned below the transfer rail 15. Since both fingers 74 of the chuck 70 are in an open state, an enamel line 13 of the core 12 is positioned therebetween. Among the enamel lines 13, two strands having a relatively long length are positioned.

Next, the chuck drive source 60 is driven such that the finger 74 of the chuck 70 grips two relatively long strands of the enamel wire 13. That is, when the driving rod 61 of the chuck drive source 60 is accommodated therein, the chuck drive plate 67 provided at the lower end of the elevating drive bar 65 while the elevating connecting plate 63 is lowered downward. This will descend. Thus, the chuck driving plate 67 is no longer supporting the finger driving rod 77, the finger 74 of the chuck 70 is in contact with the tip of the finger by the elastic force of the restoring spring (79). While holding the enamel wire 13 (see Fig. 7d).

In the state where the chuck 70 grips the enamel wire 13, the driving rod 37 of the lifting drive source 36 is raised. In this case, as shown in FIG. 7E, the driving rod 37 is no longer directly supported by the first transfer base 26. In addition, while the spring guide 38 is supported by the support spring 27, the second transfer base 30 is entirely supported by the support spring 27. At this time, since the spring guide 38 is separated from the first transfer base 26, the spring guide 38 is lowered to some extent by the load of the second transfer base 30. However, the elevating guide rod 28 is supported to be elevated by penetrating the guide bearing 32 so that the entire second transport base 30 may be stably supported.

On the other hand, the spring guide 38 is elastically supported by the support spring 27 to be configured to support the second transfer base 30 for the following reasons. When the chuck 70 rotates while holding the enamel wire 13, the enamel wire 13 is twisted with each other and its length is relatively reduced. In this case, the chuck 70 has a tendency to rise upward. Therefore, if the driving rod 37 is operated with its front end connected to the first transfer base 26, the enamel wire 13 can be pulled off while the chuck 70 does not rise. .

In the next step, the enamel wire 13 is twisted while the chuck 70 is rotated by the driving motor 40. The driving force of the drive motor 40 is decelerated by the reducer 41 and transmitted to the drive pulley 42. In the drive pulley 42, a plurality of interlocking pulleys 51 through the drive belt 43, the first connection pulley 47, the second connection pulley 48, the connection drive shaft 45, the interlocking belt 50. The driving force is transmitted.

When the linkage pulley 51 is rotated, the chuck 70 rotates while the rotation shaft 53 integrally rotated with the linkage pulley 51 rotates. At the time of rotation of the chuck 70, the finger driving rod 77 installed through the rotation shaft 53 is also rotated together. As the chuck 70 is rotated as described above, the enamel wire 13 twisted by the chuck 70 is shortened, and the length thereof is shortened, and the chuck 70 including the second transfer base 30 rises by that amount. do. This is possible because the drive rod 37 of the elevating drive source 36 is not connected to the first transfer base 26.

Here, the interlocking belt 50 is in contact with the interlocking pulley 51 in a relatively long section by the idle pulley 52 is transmitted power. In addition, the degree of rotation of the interlocking pulley 51 is sensed by the sensor 49 which is a photosensor. When the interlocking pulley 51 is rotated as much as the sensor 49 is designed to check the rotation speed of the interlocking pulley 51, the driving of the driving motor 40 is stopped.

Next, as shown in FIG. 7G, the tip of the finger 74 of the chuck 70 is opened by the chuck driving source 60. In this way, the core 12 in which the enamel wire 13 is twisted can be transferred.

When the tip of the finger 74 is opened, when the driving rod 61 protrudes relatively from the chuck driving source 60, the lifting connecting plate 63 is raised while raising the lifting driving rod 65. When the elevating driving rod 65 is raised, the chuck driving plate 67 is raised to raise the finger driving rod 77. Therefore, the interlocking pin 78 of the tip of the finger driving rod 77 drives the finger 74 so that the tip of the finger 74 is opened.

Next, as shown in FIG. 7H, when the transfer driving source 21 is operated, the first transfer base 26 is moved to the right in the drawing, and transfers the components provided in the second transfer base 30. Let's do it. Then, when the driving rod 37 of the elevating drive source 36 protrudes, the initial state shown in FIG. 7A is obtained.

On the other hand, after the chuck 70 is rotated in FIG. 7F to twist the enamel wire 13, it must stop at a specific position to twist the next enamel wire 13. The sensor 49 is used for this purpose. That is, the position where the light emitted from the sensor 49, which is a photosensor, is sensed is the initial position of the chuck 70. Once the braiding of the enamel wire 13 is completed, the chuck 70 should always be in the initial position with reference to the data provided by the sensor 49 for the next operation.

The rights of the present invention are not limited to the embodiments described above, but are defined by what is stated in the claims, and those skilled in the art can make various modifications and adaptations within the scope of the rights described in the claims. It is self-evident.

For example, the irregularities 76 and 76 'may be any shape that can be bent and gripped by the enamel wire 13, and a configuration for driving the finger 74 may be variously designed.

In addition, although the interlocking belt 50 and the interlocking pulley 51, which are timing belts, are used to drive the chuck 70, for example, the chuck 70 rotates in the same direction by using a chain and a sprocket instead. It may also be configured to.

In the enamel wire braiding device of the balun transformer production machine according to the present invention as described in detail above can be expected the following effects.

In the present invention, each enamel provided in a plurality of cores is twisted at the same time. The power for this is transmitted using a timing belt. Therefore, the entire interlocking pulley for rotating the chuck twisting the enamel wire has the same rotation by the timing belt, so that the entire enamel wire is uniformly twisted.

In addition, in the present invention, the gripping iron bent and gripped the enamel wire at a portion where both fingers constituting the chuck are in contact with each other, so that the enamel wire can be twisted more securely.

Further, in the present invention, since the second feed base provided with the chuck is supported by the support spring with respect to the first feed base in the process of twisting the enamel wire, the chuck can be stably twisted without pulling the enamel wire. It also works.
