Embodiment Construction

[0019] Hereinafter, the coil manufacturing apparatus 100 and the coil manufacturing method according to the embodiment of the present invention will be described with reference to the drawings. Further, in each of the drawings, the scale of each structure is appropriately changed, and it is not necessary to comply with the size of the illustrated.

[0020] First, the coil 1 obtained by the coil manufacturing apparatus 100 and the coil manufacturing method of the present embodiment will be described.

[0021] The coil 1 is for, for example, a non-contact power supply device, such as figure 1 with figure 2 As shown, the coil 1 is a so-called planar coil that causes the plurality of wires 2 on the same plane. The winding start end (starting wire 1a) of the coil 1 is located in the inner circumference, the winding terminal (end wire 1b) is located in the outer circumference.

[0022] The coil 1 is wound by winding a plurality of wires 2 in a radial direction of the coil 1. The plura...

Abstract

The present invention provides a coil manufacturing device and a coil manufacturing method. The coil manufacturing device (100) includes: an adjustment mechanism (50) for adjusting the interval of a plurality of wires (2) sent to the winding core (25), and a plurality of wires wound on the winding core (25) (2) The heating device (60) of bonding, the adjustment mechanism (50) is equipped with the rod (52) that can rotate around the rotation center axis parallel to the axis of the winding core (25), and is arranged side by side at a predetermined interval. A plurality of rollers (53) that are arranged on the rod (52) and are respectively supplied to a plurality of wires (2) of the winding core (25) are erected, and the rod (52) is configured to be able to move between the first position and the second position The first position is the position where the wires (2) sent from the roller (53) to the winding core (25) are relatively close to each other, and the second position is the position where the wires (2) sent from the roller (53) to the winding core (25) are relatively close to each other. The position where the wires (2) of the wire core (25) are relatively separated from each other.

Description

Technical field [0001] The present invention relates to a coil manufacturing apparatus and a coil manufacturing method for winding wire on the winding core. Background technique [0002] A coil is disclosed in JP2000-128433A, which is formed in a plurality of parallel lines that will be bonded in parallel to one plane in one plane in a plan view. [0003] The coil of the JP2000-128433A is formed by forming a plurality of parallel lines and winding the plurality of parallel lines in the width direction, and the plurality of parallel lines cover the conductor of the thin line covered by the insulating layer in parallel. . When such a coil is formed, the length of the thin line located in the radially inward of the wrapped plurality of wraps is different from the thin wire located outside the outer side, and therefore there is a joint stripping of the thin lines. Inventive content [0004] It is an object of the present invention to provide a coil manufacturing apparatus and a coil...
