Abstract

PURPOSE:To provide a winding apparatus which eliminates bad influence on productivity and reliability due to manual operation, which automates winding operation, whose productivity is enhanced and whose reliability is high regarding the winding operation of an inductance component using a thick wire material. CONSTITUTION:A bobbin 11 is turned by the rotation of a motor 1 via a first gear to a fourth gear 2, 3, 5, 6. At this time, winding operation is performed by synchronizing the rotation of the bobbin 11 with the descent of a holding chuck 8 in such a way that the length of a wire material wound on the bobbin 11 becomes identical to the length of a wire material sent out from a nozzle 7. Thereby, the wire material can be sent out without applying any tension to the bobbin 11, and thick wire material can be wound automatically.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device mainly used for winding an inductance component using a thick wire.

[0002]

2. Description of the Related Art Conventionally, when a thick wire rod is used in the manufacture of an inductance component, it is impossible to hold the wire rod on a bobbin for winding because the tension applied to the wire rod becomes large. For that purpose, FIG. 4 (a), (b),
As shown in (c), first, only the winding is performed, then the wire is held in the wire holding portion, and the wire is cut into a prescribed length. Further, in the product using the closed loop core as shown in FIG. 5, all the winding work relies on manual work.

[0003]

However, in the above-mentioned conventional method, a product having a thick wire in the manufacture of an inductance component always requires manual work, which is problematic in terms of both productivity and quality. However, there has been a demand for solving these problems.

The present invention solves the above-mentioned problems of the prior art, and an object of the present invention is to provide a winding device capable of improving the productivity by automating the winding process when a thick wire is used. To do.

[0005]

In order to solve this problem, a winding device according to the present invention includes a bobbin holding portion that rotatably holds a bobbin provided with a holding portion that holds the start and end of a wire rod.
A drive unit that rotates the bobbin held by the bobbin holding unit, a nozzle that guides the wire rod supplied from a supply unit equipped with a wire rod for winding the bobbin to the bobbin, and rotation of the bobbin. A holding chuck for driving the wire rod to the bobbin through the nozzles driven in synchronization with each other, and a cutter for cutting the wire rod wound on the bobbin.

[0006]

[Operation] With this configuration, in the winding process of the inductance component when a thick wire is used, the winding work which relied on manual work can be automated, and the winding process with high productivity and reliability is realized. It is possible to provide a winding device that can do this.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
Will be explained.

FIG. 1 is a perspective view showing the structure of a winding device according to the embodiment, and FIG. 2 is a front view of the main part.

In FIGS. 1 and 2, reference numeral 1 is a motor that performs a rotary motion as a drive unit, 2 is a first gear connected to the tip of the main shaft of the motor 1, and 3 is the first gear 2 and a timing belt. The second gears 4, which are stretched by and transmit the rotation of the motor 1, are shafts for transmitting the rotation from the second gear 3 to a gear arranged on the opposite side (not shown). Reference numeral 11 is a bobbin having a gear structure on the collar portion, and reference numerals 5 and 6 are third portions for engaging with the gears of the bobbin 11 to perform winding.
The gear No. 4, the fourth gear No. 7, and the nozzle No. 7 are nozzles for guiding the wire rod to the bobbin 11, and can move in the left-right direction according to the winding position. A holding chuck 8 holds a wire rod by opening and closing and can slide up and down. Reference numeral 9 is a holding guide for rotatably holding the third and fourth gears 5, 6 and the bobbin 11, 10 is a cutter for cutting the wire rod, and 12 is a wire rod for holding the wire rod when winding the wire rod on the bobbin 11. It is a holding unit.

The operation of the winding device of the present invention constructed as above will be described below with reference to FIG. Figure 3
3A shows a state before the wire rod is inserted into the bobbin 11, and the wire rod is held by the holding chuck 8. From this state, the wire rod is held by the holding chuck 8 as shown in FIG. 3B. It is pushed out and inserted into the wire rod holding portion 12. Next, as shown in FIG. 3C, the holding chuck 8 is opened and returned to its original position, and the holding chuck 8 is closed. Then, as shown in FIG. 3D, the bobbin 11 is rotated by the rotation of the third gear 5 and the fourth gear 6 to perform winding. At that time, as shown in FIG. The holding chuck 8 is pushed down in synchronization with the rotation of the bobbin 11 so that the length of the wire wound around the wire 11 and the length of the wire sent out from the nozzle 7 become the same. Figure 3 after winding
As shown in (E), the holding chuck 8 is opened and returned to the original position, the wire rod is held and the cutter 10 cuts the wire rod, and the winding on the bobbin 11 is completed.

As described above, in the winding device according to the present invention, the wire rod can be fed out without applying tension to the bobbin 11 by synchronously moving the rotation of the bobbin 11 by the gear and the lowering of the holding chuck 8. It is possible to automatically wind a thick wire on the bobbin 11.

In the present embodiment, it is explained that the winding device is effective for the winding using the thick wire, but the winding device can be used for winding regardless of the thickness of the wire. Needless to say.

[0013]

As described above, the winding device according to the present invention is
It becomes possible to automate the winding when using a thick wire, which was an issue of automation in the conventional winding process, and it is possible to eliminate the adverse effect on productivity and reliability due to human intervention,
It is possible to improve productivity and reliability, and has an extremely high industrial value.
