Description of the Invention (I) [Industrial Application Field] The present invention relates to a winding device for winding a coil such as an ignition coil of an engine. [Known technology] In the past, in order to ensure the insulation of the coil, coiled wires (copper wires) covered with enamel were used to wind the coils, or coils with no insulation coating were used to wind the coils. The coil is immersed in an insulating varnish for impregnation and dried. In addition, conventionally, the ignition coil of an engine is covered with a thermosetting resin which is difficult to peel off, and the wire element is covered with insulation. The wire element assembly is composed of primary and secondary coils wound around each bobbin. The coil assembly is housed in a coil case, and a molten thermosetting insulating resin (epoxy resin) is injected into the coil case (in this case, the insulating resin is impregnated with the primary and secondary coils). Molded into one body. [Problems to be Solved by the Invention] The problem to be solved is that if a coil element wire with an insulation coating is used to wind the coil, it is necessary to apply an insulation coating to the coil element wire in other processes of winding. In addition, when the insulating varnish (resin) is impregnated after the coil is wound, the varnish (resin) is not impregnated sufficiently on a coil having a plurality of thin coil plain wires wound thereon, so that the insulation property is impregnated. It deteriorates and there is a problem that the coil performance is reduced and the coil heats up. 3 This paper size is applicable to China National Standard (CNS) A4 specification (21〇X 297 meals) ------------------- Order --------- (Please read the precautions on the back before filling out this page) 583693 A7. __ _B7__ 5. Description of the invention (>) At this time, especially in the case of the ignition coil of the engine, there are many windings with a diameter of about 0.0. The secondary coil of a 5mm thin wire element (copper wire) is hardly impregnated with insulating varnish (resin). In addition, conventional engine ignition coils, such as conventional engine ignition coils, which are injected into a coil case with a thermosetting insulating resin and molded into one body, cannot be separated and taken out after the resin is hardened. [Means for solving the problem] The present invention is to form a winding device in order to ensure the insulation of the coil to be wound during winding without having to prepare a coiled plain wire with an insulation coating in advance. The tension side sends the coiled plain wire supplied from the spool from the nozzle and winds it around the bobbin mounted on the rotating shaft. It is characterized in that the molten insulating resin is put into the inside of the nozzle to cover the insulating resin. On the coil plain line sent by the nozzle. In addition, in the present invention, in order to reuse the coil element wires of the wound coil, a thermoplastic resin is used on the resin of the coil element wires to be insulated and coated. At this time, the insulating resin is injected into the coil case that houses the coil group, and the engine ignition coil is cured and molded into a body. The thermoplastic resin is used for the resin of the mold, which can be used after molding. This resin is melted by heating to separate and take out the coil group.

The drive unit 8 is constituted by, for example, a mechanism unit that uses a motor as a drive source to rotate the rotary shaft 5 and a mechanism unit that uses a linear motor as a drive source to advance and retreat the rod 14 equipped with the nozzle 4. The structure of each of these agencies is a general structure, and the details of these structures are omitted here. In such a winding device shown in FIG. 1, as shown in FIG. 2, a funnel-shaped hopper 10 ′ for supplying insulating resin particles 9 is provided inside the nozzle 4, and the periphery of the nozzle 4 is provided in advance. The heating wire η, and the switching circuit 12 and the heating power π enable the heating power 13 to be turned on or off by the switching circuit 12 under the control of the controller 7. When the heating wire 11 is energized during winding, the interior of the melting nozzle 4 is heated. The pellets 9 are coated with an insulating resin on the coil element wires 3 sent from the nozzle 4. The nozzle 4 is made of a metal material having thermal conductivity. According to the present invention, when the coil element 3 passes through the nozzle 4, it will be covered with an insulating resin with good adhesion, thereby ensuring the insulation of a coil with multiple layers of winding, and it is easy to obtain a high coil performance with less heat generation. Quality coil. Especially for the ignition coil of the engine, it is beneficial to produce a secondary wire coil in which a thin plain wire with a diameter of about 0.05 mm is repeatedly wound many times.

Explanation of the invention (\) In the present invention, a thermoplastic material is used on the resin of the insulation-coated coil element 3. Therefore, when discarding the coils wound as described above, the coils wound on the bobbin 6 are applied. Insulated-coated coils made of thermoplastic resin are heated in a heater to melt-remove the insulated-coated resin and recycle the wire element 3. Coil units are individually wound on each bobbin. The primary coil and secondary coil are assembled together with the connection terminal and the iron core. The insulating resin is injected into the coil housing containing the coil group, and the engine ignition coil is cured and molded into an integrated body. Thermoplastics are used for the resin of the mold. After molding, the molten resin is heated, and the wire coil group is taken out from the coil shell, and the wire elements, connection terminals, and iron core of the coil group can be separated one by one. [Effect of the Invention] The winding device of the present invention is applied on the side With a fixed tension, the threaded element thread supplied from the spool is sent out of the nozzle. When winding on a bobbin mounted on a rotating shaft, the molten insulating resin is placed inside the nozzle to cover the insulating resin. For the coiled plain wire sent from the nozzle; when the coiled plain wire passes through the nozzle, it will be covered with an insulating resin with good adhesion to ensure the insulation of the multi-layer wound coil, and it is easy to obtain good coil performance.
