And a coil insertion portion 6 for inserting the air-core coil formed in the coil forming portion 5 into a predetermined position on the substrate 3.

In the substrate transfer section 4, it is placed in a groove 2A provided in the center of the upper surface of the gantry 2 in parallel with the direction indicated by the arrow a, and is placed on the substrate transfer stand 10 from the preceding predetermined production line. The substrate 3 to be processed, which is supplied as described above, is conveyed along the groove 2A.

In this case, the substrate transfer section 4 is adapted to temporarily fix and hold the substrate mounting tables 10 that are sequentially supplied at a predetermined position on the gantry 2 (hereinafter, referred to as a processing position). Thus, the substrate 3 placed on the substrate mounting table 10 is positioned and held at the processing position for a predetermined time required for inserting the air-core coil into the substrate 3.

On the other hand, the coil forming section 5 comprises a roller 11, a tensioner 12, an insulating film peeling section 13, a wire material supplying section 14, a winding section 15 and a coil transferring section 16.
Roller 1 from bobbin (not shown) loaded inside pedestal 2
The wire 17 is supplied to the insulating film peeling portion 13 through the 1 and the tensioner 12 in order, and the insulating film of the portion of the wire rod 17 corresponding to the end portion of the air-core coil is peeled off in the insulating film peeling portion 13.

In the coil forming section 5, the wire material 17 from which the insulating film has been peeled off is then supplied from the wire material supply section 14 to the winding section 15 by a predetermined amount.
The spindle 18 is rotationally driven in a state in which the tip of the wire 17 is sandwiched by a chuck (not shown) provided at the tip of the spindle 18 of the winding part 15, and the wire supply part 14 rotates the spindle 18 at this time. The wire rod 17 is wound around the winding shaft 19 with a predetermined pitch by moving in a direction parallel to the axial direction of the winding shaft 19 in synchronization.

Further, in the coil forming unit 5, when the winding work is completed, the wire rod cutting unit 20 fixed to the wire rod supplying unit 14 is driven to cut the wire rod 17 at a predetermined position, so that the winding shaft 19 is wound. The wound wire 17 is separated from the other wire 17 to form an air-core coil, and then the coil transfer portion 16 moves rearward to move the winding shaft 1
The wire rod 17 (air core coil) fitted in 9 is transferred to the transfer shaft 21, and then the coil transfer portion 16 moves forward and returns to the origin position, whereby the transfer shaft 21 The air-core coil transferred to is conveyed to the coil supply position for the coil insertion portion 6.

The coil transfer section 16 is provided with first and second coil terminal formation blocks 22A and 22B on the rear side of the transfer shaft 21, and the first and second coil terminal formation blocks 22A are provided. 22B and 22B are configured to, when the air-core coil is transferred by the coil transfer unit 16, perform shape processing of each end of the air-core coil and a continuity test between each end.

The coil insertion part 6 has a fixed part 25 fixedly arranged on the pedestal 2, and a first movable body 26 is arranged on the fixed part 25 so as to be movable in the front-rear direction. A second movable body 27 is arranged on the first movable body 26 so as to be movable in the left-right direction, and a coil chuck portion 28 is attached to the second movable body 27.

In this case, the coil chuck portion 28 has a chuck portion 30 having a pair of first and second holders 29A and 29B which can be opened and closed by an actuator (not shown).
And a holding portion 31 for holding the chuck portion 30 in an upward direction indicated by an arrow c, a downward direction opposite to the upward direction, or a rotational direction indicated by an arrow d so as to be movable or rotatable.

Thus, in the coil insertion part 6, the air-core coil transferred to the transfer shaft 21 of the coil transfer part 16 is conveyed by the coil transfer part 16 to the coil supply position for the coil insertion part 6. When the first and second movable bodies 25 and 26 and the holding unit 30 are driven at a predetermined timing, the air core coil transferred to the transfer shaft 21 is moved to the first and the first of the chuck unit 30. The two holders 29A and 29B are held so as to be sandwiched and conveyed, and the respective end portions of the air-core coil are inserted into the substrate 3 at predetermined positions.

In this way, the coil winding device 1 is
While the air-core coils are sequentially formed, the formed air-core coils can be sequentially mounted in predetermined positions at predetermined positions on the substrate 3 sequentially supplied from the preceding production line.

By the way, in the coil winding device 1, if there is a defect in maintenance of each part of the device, the conduction between the terminal parts of the air-core coil is defective, or the shape of the air-core coil is deformed. Shape defects may occur. In addition, in the substrate 3 supplied from the preceding production line, the positions of the insertion holes corresponding to the respective end portions of the air-core coil may be misaligned. In such a case, the substrate 3
A defective insertion of the air-core coil may occur.

Therefore, in this coil winding device 1, for example, the coil transfer section 16 and the substrate transfer section 4 on the gantry 2 are arranged.
A coil housing box (not shown) having an opening at the upper end is disposed between the machining position and the processing position of the air-core coil which is defective as described above or the air-core coil which is defectively inserted (hereinafter, these The defective coil is held by the coil insertion portion 6 and conveyed to the upper part of the coil storage box, and then the defective coil is dropped to store the defective coil in the coil storage box.

Thus, in this coil winding device 1, a good air core coil can be inserted into the substrate 3.

[0017]

In the coil winding device 1 having such a structure, as described above, the tensioner 12, the insulating film peeling portion 13, the wire material supply portion 14, the winding portion 15, and the wire material of the coil forming portion 5 are arranged. Since the cutting unit 20, the coil transfer unit 16, the coil insertion unit 6, and the above-mentioned coil housing box are dispersedly arranged on the gantry 2 in a planar shape, the entire device has a relatively large width.

In this case, since such a coil winding device 1 requires a large installation space,
In recent years, there is an increasing demand for miniaturization of the entire device.

Therefore, as a method of miniaturizing the coil winding device, the tensioner and the insulating film peeling portion are sequentially arranged from one end along the longitudinal direction on the upper stage of the elongated base plate, and then the upper face of the base plate is treated from the upper stage. The wire rod supply unit and the wire rod cutting unit are sequentially arranged in a row along the downward direction approaching the line, and then the winding unit and the coil are sequentially arranged from the lower side of the wire rod cutting unit (that is, the lower stage on the base plate) to the other end. The transfer section is arranged in one row, and the coil insertion section is arranged outside the other end so as to be movable in the vertical direction. In this way, each section is three-dimensionally arranged in two rows. It is conceivable to dispose the plate on the pedestal via the columns and to dispose the substrate transfer unit movably on the pedestal facing the lower end of the coil insertion portion.

By the way, in the coil winding device constructed by such a method, the coil insertion portion moves in the vertical direction uniaxially, so that the degree of freedom with respect to the arrangement position of the coil accommodation box is lowered, and the coil accommodation box is For example, it may be possible to arrange the opening on the upper side or the lower side of the substrate transfer section so as to face the lower end of the coil insertion section.

However, when the coil accommodation box is first arranged above the substrate transfer section, the coil accommodation box hinders the downward movement of the coil insertion section for inserting the air-core coil into the substrate. Therefore, in such cases, normally,
It is conceivable that the coil housing box is made to stand by at a predetermined position other than the moving range of the coil insertion portion and is moved to the lower side of the coil insertion portion when the defective coil is accommodated.

However, in this case, a moving mechanism for moving the coil housing box is required, which is considered to complicate the apparatus configuration.

On the other hand, when arranging the coil accommodation box below the substrate transfer section, the position of the coil accommodation box is fixed with respect to the lower end of the coil insertion section, and the substrate transfer section is moved when the defective coil is accommodated. It is considered that the defective coil to be dropped from the coil insertion portion can be housed in the coil housing box by moving the defective coil so as to be out of the trajectory.

In this case, however, since the drop point of the defective coil in the coil storage box is fixed, the defective coils are piled up in the coil storage box so that the drop point is the apex. It is considered difficult to evenly house defective coils inside the coil housing box. Therefore, in such a coil winding device, the number of defective coils that can be actually accommodated is reduced with respect to the internal capacity of the coil housing box, and the coil housing box must be frequently replaced. It is considered that there is a problem that the storage efficiency of the defective coil is extremely low.

The present invention has been made in consideration of the above points, and an object thereof is to propose a coil winding device capable of improving the housing efficiency of the coil.

[0026]

In order to solve such a problem, according to the present invention, a coil carrying means for holding and carrying a coil and a coil carrying means is positioned below the coil carrying means in the direction of gravity. A coil housing box and a moving means for moving the coil housing box to the drop position of the coil that is dropped by being released from the coil transport means at a predetermined position are provided.

In the present invention, the coil is held by the coil carrying means, carried and released to drop at a predetermined position, and at the same time, the moving means moves the coil housing box to the coil dropping position. By changing the drop point of the coil in the opening of the box according to the number of times the coil is accommodated and receiving the coil in the coil accommodation box, the coils can be easily and evenly accommodated inside the coil accommodation box. be able to.
