However, the manufacturing process of the transformer is complicated, the manual assembly requires a great deal of labor and cost, and the uniformity or reliability of the quality is not good.

The main manufacturing process of the transformer is the winding process. For example, 16 pins as shown in FIG. 9 (of which P0
The transformer having 6 and P15 is not used) has a winding as shown in FIG. That is, eight windings are performed. When this process is disassembled, as shown in Table 1, (Table 1 shows only the first three winding processes, I, II, and III processes). The same applies to the following steps IV to VIII.) In each winding part step of 8 times, a barrier tape and an insulating tape are wound in addition to the wire. The barrier tape is wound, the wire is wound, the starting end of the insulating tape is wound, the wire is wound around the pin at the end of the wire, and the insulating tape is wound. This is repeated eight times as a whole.

As described above, the winding process and other processes are extremely complicated, and in the present situation where manpower is used, much labor and cost are required. Further, even if an attempt is made to automate the process to save labor, the process is complicated, requires a long equipment, and it is difficult to effectively automate the process.

The present invention provides an automatic transformer manufacturing apparatus which solves the above-mentioned problems of the conventional ones, enables effective automation, can reduce the size of manufacturing equipment, and is ready to be applied to transformers of different sizes. The purpose is to

〔Example〕

Before explaining the device, the basic work contents will be explained. FIG. 11 shows the bobbin 1 of the transformer. The bobbin 1 comprises a drum 2, flanges 3 and 4, pin supports 5 and 6,
The pin supports 5 and 6 are convex portions 9 and 10 separated by concave grooves 7 and 8.
And pins P01 to P08 and P11 to P18 are provided on the convex portions 9 and 10, respectively. Protrusions 11 and 12 are provided outside the protrusions 9 and 10. A hole 13 is provided at the center of the drum 2.

To give a basic explanation of the wire winding work, in FIG. 12, the stretched wire 14 is twisted to the pin P ₀ to form the starting end 15 (how to twist it, other methods will be described later), and to the projection 11. It hangs around and leads to the surface of the drum 2 through the groove 7.
The wire 17 is wound around the drum 2 by bending the bobbin 1 in the direction of an arrow 16 and bending it at a right angle to the axis of the drum 2 by bending the wire 17 at a substantially right angle. The end is entangled with the pin on the same side as the pin P ₀ , but in order to avoid complication of the drawing, if the end of the pin is shown by the pin P ₁ on the opposite side for convenience, the wire 18 near the end is After being bent in the axial direction of the drum 2 at a substantially right angle from the winding direction, it is guided to the concave groove 8 and is wound around the protrusion 12 to be entangled with the pin P ₁ to form the end 18. Excessive wire 19 at the end 18 is guided to the temporary holder 20 so that a part of the wire is clamped and held, and a nozzle 21 for supplying the wire 19 is provided.
A tension wire 22 is provided between the tension wire 22 and the (described later). Starting point 15
The side wire 14 is an extension of the tension wire 24 from another temporary holding tool 23, which is left in the previous step. In this state, the surplus wires 14 and 19 at the starting end 15 and the ending end 18 are S
It is cut at ₀ and S ₁ . Since the tension wire 22 is left, the nozzle 21 can bend the starting end of the next bobbin.

The parts of the starting end 15 and the ending end 18 are soldered in a later step.

Regarding the winding part process number I in Table 1, FIGS. 13 (a) to 13 (e)
Will be described.

First, as shown in FIG. 13 (a), the starting end is entangled with the pin P13, and the wire 25 is guided onto the drum 2 through the projection and the concave groove. Next, after the barrier tapes 26 and 27 are wound,
As shown in (b), the wire 25 is bent at a right angle by the bending guide pin 28, and when the bobbin 1 is rotated in the direction of the arrow 29, the wire 25 is wound around the drum 2 as shown in FIG.
Therefore, if the tip of the insulating tape 30 is attached to the surface of the wire 25 already wound before the last winding of the wire 25 is performed and the bobbin 1 is further rotated a little, the same figure (d) As shown in, the tip of the insulating tape 30 can be entangled under the final winding portion of the wire 25. After that, the bending guide pin 28 causes the wire 25
Is bent perpendicularly to the axial direction of the bobbin 1 and is entangled with the pin P14 through the groove and the projection. Next, after temporarily holding the wire ends in the temporary holder 20 (FIG. 12), the excess wires in the pins P13 and P14 are cut. If the bobbin 1 is further rotated in the direction of arrow 29, FIG.
The insulating tape 30 is wound as shown in (e).

By expanding and contracting the cylinder 129, the gear 125 meshes with the gear 86 so that the holding shaft 67 is rotated by the pulse motor 122, or the gear 125 is removed from the gear 86, and instead the rack 87 is used. Can be engaged with each other to stop the holding shaft 67.

The operation of the winding station I having the above concept will be described.

At the bobbin supplying station 31, the jig 66 having the bobbin 33 mounted thereon is moved to the winding station I and fixed at a predetermined position. Until this time, the restraining means 36, the wire operating means 37, and the tape adhering means 38 are pulled out of the bobbin passing area 39 as shown in FIG. 6, and the shaft end supporting means 91 and the rotation driving means 92 are at the positions shown in FIG. Than bobbin 33
It stands by so that it does not interfere with the jig 34.

When the bobbin 33 is positioned and fixed at a predetermined position, the above-mentioned processing means comes close to or comes into contact with the bobbin 33, and FIGS.
It becomes the state of the figure. However, initially the insulating tape attaching mechanism 105
The guide plate 111 is separated from the bobbin 33.

To explain in comparison with the process of FIG. 13, first, the holding shaft 67 is slightly tilted by the pulse motor 122 to align the direction of the pins (P01 to P18) of the bobbin 33 of FIG. 13 with the Z direction. Next, the wire operating means 37 is driven to move the nozzle 97 with respect to the pin P13 to a position near the rotation center 101 in FIG. At this time, the wire 96
Since the tip of the wire is held by the temporary holder 103, the wire 96 (wire 2 in FIG. 13) is moved as the nozzle 97 moves.
5) is pulled out. Next, the motor 97 drives the nozzle 97
Eccentrically rotate the wire 96 around the pin P13.
Can be entangled. After that, the excess wire is cut by the nippers 99 (S ₀ position in FIG. 12), the nozzle 97 is moved, and the wire 96 is moved to the projection 11 (FIG. 12) and the groove 7.
The state shown in FIG. 13 (a) is obtained through the space (FIG. 12).

Next, the restraining means 36 is activated, and the bending guide pin 94 is applied to the position 28 in FIG. 13 (b). Bobbin 3 at this time
3 (FIG. 13) may be rotated so that the bending guide pin 94 abuts the position 28 at a right angle. Next, the nozzle 97 is moved in a direction at right angles to the axis of the bobbin 33, and the wire 25 (the same as 97 in FIGS. 6 and 8) is bent at right angles and extended in the tangential direction of the drum 2 as shown in FIG. 13 (b).

In this state, the barrier tape attaching mechanism 106 is operated,
The guide plate 111 is brought into contact with the drum 2 of the bobbin 33.

Next, when the bobbin 33 is rotated in the direction of the arrow 29 in FIG. 13 (b), the barrier tapes 26 and 27 (FIG. 119) are wound, and after proper rotation (for example, 2 to 3 rotations), the rotation is stopped. The barrier tapes 26, 2 are stopped by the cutter 116.
7 is cut, and the guide plate 111 is separated from the bobbin 33.

On the other hand, the wire 25 is simultaneously wound by the rotation of the bobbin 33, but the shape of the right-angled bend is broken by the wire tension (the bending guide pin 94 before starting to rotate).
In order to prevent the wire 25 from being pulled in), the pressing roller 95 suppresses the already wound portion of the wire 25 and resists the wire tension.

The bobbin 33 is rotated again, and the insulating tape attaching mechanism 105 is operated in the state shown in FIG. 13 (c) immediately before the winding of the predetermined number of wires 25 is completed, and the insulating tape 30 (see FIG.
By sticking the end of 4) and then rotating the bobbin 33 slightly, the starting end of the insulating tape 30 can be put under the final winding part of the wire 25 as shown in FIG. 13 (d).
At this point, the rotation is stopped and the nozzle 97 (Fig. 12) is moved to move the wire 25 to the groove 8 and the protrusion 12 as shown in Fig. 12.
The hanging, tied to pin _{P 1} (FIG. 13 (d) P14), the twelfth wire at the point of FIG. _{S 1} was fixed to hold the wire by further temporary retainer 20 (FIG. 8 103) Disconnect.
At this time, the end of the wire (Fig. 12) coming out of the nozzle 97 (Fig. 12) is attached to the temporary holder 20 (Fig. 8).
It is held in 03).

Next, when the bobbin 33 is rotated, the insulating tape 30 (6th
(Fig. 104) is wound, and when the number of turns reaches a predetermined number, rotation is stopped, cutting is performed by the cutter 116, and the guide plate 111 is released.

After the first-stage winding and tape attachment are completed in this way, the processing means are retracted to their original positions, and the jig 34 is then sent to the winding station II.

In the winding stations II to VIII, winding is performed by the same process as in the winding station I.

Further, the solder station 40 to the transfer station 46
In the above, the work is performed as described above, and the completed transformer is taken out by the conveyor 47.
