The present invention relates to a balun transformer maker, and more particularly, to an enamel wire inserting apparatus of a balun transformer maker for bending and inserting an enamel wire constituting a lead into a core constituting a transformer.

Balun transformers are used for frequency conversion or frequency filtering 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 this automated balun transformer manufacturing machine, in order to transfer a plurality of cores to each process position, the cores are transported adjacently without any gaps between the cores, and in particular, in the direction of connecting the through-holes formed by penetrating both ends up and down. Since it is conveyed, it is difficult to bend and insert the enamel wire.

Therefore, the configuration for cutting and bending the enamel wire and inserting it into the core should be rotated at least 90 ° while descending. In order to satisfy such an operation characteristic, the configuration becomes very complicated, resulting in poor operation reliability and an increase in defects.

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

In the enamel stripping device C, the enamel wire 13 in which the insulating layer of the section is stripped is cut through the guide hole 26 of the cutting guide 25 penetrating the frame 20. It is supplied to extend to the guide channel 41 of. The front end of the enamel wire 13 is located at the front end of the guide channel 41.

When the tip of the enamel wire 13 stops at the desired position as described above, the push cylinder 70 is operated so that the pusher 74 presses the enamel wire 13 to one side of the frame 20. At this time, the housing 75 of the pressing hole 74 presses the enamel wire 13 by the elastic force of the contact spring 77, so that the enamel wire 13 is not plastically deformed flat.

In this way, the block driving plate 33 is lowered by the lifting and lowering drive 30 while the one end of the enameled wire 13 is pressed by the pressing hole 74. When the block driving plate 33 is lowered, the lifting column 35 at both ends is guided along the guide bearing 28 to lower the cutting block 40 is lowered.

When the cutting block 40 is lowered, the cutting blade 43 of the cutter 42 is guided along the cutting guide surface 25 'of the cutting guide 25 to cut the enamel wire 13. If the cutting block 40 continues to descend even after cutting the enamel wire 13, the bending guide 65 is inserted into the bending slot 45 of the cutting block 40. (See Figure 7b)

Accordingly, the enamel line 13 is bent in a 'U' shape in the bending slot 45. At this time, the length of both ends of the bent enamel line 13 is determined according to the position of the bending slot 45.

When the enamel wire 13 is bent by the bending guide 65, the enamel wire 13 is located in the guide groove 45 'to make its shape. In addition, both ends of the enamel line 13 bent in a 'U' shape is in close contact with the guide grooves 45 'by elastic restoring force, respectively, so that they do not fall arbitrarily.

At the point at which the enamel wire 13 is bent, the bending guide 65 is rotated in the state shown in FIG. 7C by the driving of the guide drive source 60 so that the cutting block 40 continues. Allow you to descend. That is, while the drive rod 40 of the guide drive source 60 is received inside, the drive bracket 63 is raised. When the driving bracket 63 rises, the linkage pin 67 and the linkage hole 64 interlock to cause the bending guide 65 to rotate about the rotation shaft 65 '.

The cutting block 40 continues to descend to the upper portion of the core 12 in the conveying rail (14). In this state, the push drive source 50 is driven to push the push rod 56 down so that the enamel wire 14 bent into a 'U' shape is inserted into the core 12. Thus, an enamel wire 14 is inserted into the core 12 (see FIG. 7D).

When the insertion of the enamel wire 14 is completed in this way, the cutting block 40 is raised again, and the state shown in FIG. 7A is prepared to prepare for the next operation.

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