[0025] An example of an embodiment will be described below. Note that the present invention is not limited to the embodiment described below, and appropriate modifications can be made without departing from the spirit and scope of the invention.

The winding jig 10 rotates the coil member 108 around a rotation axis 10A of the winding jig 10 to form the coil member 108 into a predetermined shape, and the heating unit 20 rotates a hot air generator 2, The cooling section 40 has a cold air generator 42 and a second air passage 44 and cools the winding jig 10 and the coil member 108 by a second blowing operation of a second air supply supplied from the cold air generator 42 via the second air passage 44, and the control section 60 controls the airflow in the first blowing operation and / or the second blowing operation.

[0027] For example, polyurethane, polyurethane nylon, polyester, polyesterimide, polyamideimide, polyimide, etc. are used for the insulating coating film 104. For the fusion layer 106, polyvinyl butyral, polyamide, thermosetting SV varnish, etc. are used and are commercially available. Note that the insulating coating film 104 and the fusion layer 106 are not limited to the above, and by configuring them in consideration of the pressure resistance and moisture resistance required for the coil 100 and the melting point and heat resistance required during manufacturing, etc., effects are exhibited in terms of the quality, cost, and productivity of the coil 100.

[0028] The airflow control preferably includes some or all of the controls relating to start / stop, airflow direction, and airflow speed in the first and second blowing operations.

[0029] In the coil manufacturing apparatus 1 according to the present invention, the winding jig 10 rotates the coil member 108 to form the coil member 108 into a predetermined shape, the heating section 20 has a hot air generator 22 and a first air passage 24 and heats the winding jig 10 and the coil member 108 by a first blowing operation of a first air supply supplied from the hot air generator 22 via the first air passage 24, the cooling section 40 has a cold air generator 42 and a second air passage 44 and cools the winding jig 10 and the coil member 108 by a second blowing operation of a second air supply supplied from the cold air generator 42 via the second air passage 44, and the control section 60 controls the airflow in the first blowing operation and / or the second blowing operation. This improves the productivity of the coil 100 manufacturing.

[0030] The coil manufacturing apparatus 1, the coil 100, the conductive member 102, the insulating coating film 104, the adhesive layer 106, the coil member 108, the winding jig 10, the heating unit 20, the hot air generator 22, the first air passage 24, the first opening / closing member 26, the cooling unit 40, the cold air generator 42, the second air passage 44, the second opening / closing member 46, and the control unit 60 according to the present embodiment correspond to the coil manufacturing apparatus, the coil, the insulating coating film, the adhesive layer, the coil member, the winding jig, the heating unit, the hot air generator, the first air passage, the first opening / closing member, the cooling unit, the cold air generator, the second air passage, the second opening / closing member, and the control unit according to the present invention. The first opening / closing member 26 opens and closes the first air passage 24, and the second opening / closing member 46 opens and closes the second air passage 44 (FIG. 2 shows a state in which the air passages 24, 44 are opened and closed by the opening / closing members 26, 46).

[0031] The heating unit 20 further includes a first driving unit 27, which moves or changes the direction of the hot air generator 22 and / or the first air passage 24 to change the airflow direction of the first air based on airflow control, thereby spraying the air toward or away from the winding jig 10 and the coil member 108.

[0032] Furthermore, the cooling unit 40 has a second drive unit 46, which moves or changes the direction of the cold air generator 42 and / or the second air passage 44 to change the airflow direction of the second air 44 based on the airflow control, thereby spraying air onto or away from the winding jig 10 and the coil member 108. The second drive unit 46 performs operations such as movement, rotation, and inversion (the dotted lines in the cooling unit 40 in FIG. 1 show the state in which the cold air generator 42 and / or the second air passage 44 have been moved or changed in direction).

[0033] The control unit 60 performs control based on control items 1 to 7 as shown in FIG. That is, the control unit 60 changes the airflow direction of the first air passage 24 and the second air passage 44 based on the airflow control by controlling the first blowing operation of the first air and the second blowing operation of the second air supplied via the first air passage 24 and the second air passage 44 so that the first air and the second air do not hit the winding jig 10 and the coil member 108 (control item 1).

[0036] Based on the airflow control, the airflow direction in the first airflow passage 24 is changed to avoid jetting onto the winding jig 10 and the coil forming member 108 (control item 5).

[0037] The airflow direction of the second air passage 44 is changed, and the winding jig 10 and the coil member 108 are cooled by a second blowing operation of the second air supplied from the cold air generator 42 via the second air passage 44 (control item 6).

[0038] Thereafter, control is performed so that the temperature of the fusion layer 106 is lower than the melting point, and the coil member 108 is fixed in a predetermined shape (control item 7).

[0039] In this embodiment, the first air passage 24 and / or the second air passage 44 may be multiple, as shown in Figures 6 and 7 (the dotted line in the heating section 20 in Figure 6 indicates the state in which the hot air generator 22 and / or the first air passage 24 have been moved or their direction has been changed, the dotted line in the cooling section 40 indicates the state in which the cold air generator 42 and / or the second air passage 44 have been moved or their direction has been changed, and Figure 7 shows the state in which the air passages 24, 44 have been opened and closed by the opening / closing members 26, 46).

[0040] In this embodiment, the winding jig 10A, hot air generators 22A, 22B, 22C, first air passages 24A, 24B, 24C, cold air generators 42A, 42B, and second air passages 44A, 44B correspond to the winding jig, hot air generator, first air passage, cold air generator, and second air passage of the present invention.

[0041] As shown in FIG. 8, the coil manufacturing apparatus 1 of this embodiment includes a temperature information table in which the melting point temperatures of multiple types of coil members 108 having different melting points, cross-sectional shape information for each coil member 108, and required hot air temperature information that is necessary and sufficient for the melting point temperature are registered, and the control unit 60 performs temperature control based on the temperature information table of the coil members 108.

[0042] As shown in FIG. 9, the winding jig 10B of this embodiment is equipped with a non-contact temperature detector 12, and the control unit 40 performs temperature control and / or opening / closing control based on the detected temperature information of the non-contact temperature detector 12 and the required hot air temperature information.

[0043] The winding jig 10B and the non-contact temperature detector 12 according to this embodiment correspond to the winding jig and the temperature detector according to the present invention.

[0044] As shown in Fig. 10, the winding jig 10C according to the present invention is equipped with a non-contact temperature detector 16. The control unit 60 performs temperature control and / or opening / closing control based on the detected temperature information of the non-contact temperature detector 16 and the required hot air temperature information.

[0045] The winding jig 10C and the temperature detector 16 according to this embodiment correspond to the winding jig and the temperature detector according to the present invention.

[0046] As shown in FIG. 11, the winding jig 10D according to this embodiment is equipped with a rotary drive motor 18 that rotates the coil member 108 around the winding jig, and the control unit 60 controls the rotational speed of the rotary drive motor 18 based on the detected temperature information from the temperature detectors 12, 16 and the required hot air temperature information.

[0048] The coil members 108A and 108B according to the present invention may have a rectangular cross section as shown in FIG. 12. When a coil is manufactured using a coil member having a rectangular cross section, the coil can be made robust and the shape retention is obtained, which is extremely advantageous in terms of production stability. Even when a coil is manufactured using a coil member having a polygonal cross section other than a rectangular cross section, it is extremely advantageous in that the coil can be made to quickly retain its shape. These advantages are particularly noticeable in the manufacture of thick coils with large heat capacity. Even when the cross section of the coil member includes a circular shape, the coil is significantly superior to the prior art in terms of production stability for coil manufacture.

[0049] The coil members 108A, 108B, conductive members 102A, 102B, insulating coating films 104A, 104B, and bonding layers 106A, 106B in this embodiment correspond to the coil members, conductive members, insulating coating films, and bonding layers in accordance with the present invention.

[0050] The predetermined shape of the coil 100A according to this embodiment may have an α-shaped appearance, as shown in Fig. 13.
