Description
Technical field
The present invention relates to a kind of manufacturing installation and manufacture method thereof of non-circular coil, can be to the circular resulting circular coil of wire coil coiled be formed, thus obtain to form the non-circular coil that is different from other circular shapes.
Background technology
In the past, for the loud speaker that in the such midget plant of mobile phone, uses, the preferred miniature loudspeaker that forms Long Circle or rectangular shape that uses.In the loud speaker of such Long Circle or rectangular shape, not to use the circular coil with ring cross-section, have rectangle, Long Circle or oval prismatic non-circular coil but use.Manufacture method as such non-circular coil, known have a following method: have the wire rod that winding around is used on the volume core of rectangle, Long Circle or the anticipated shape such as oval in the cross section, and will be taken off from this volume core by the coil that the wire rod that is wrapped on this volume core consists of, acquisition has the non-circular coil of the cross sectional shape of expection thus.
But, when having rectangle, Long Circle or oval prismatic volume core when twining the wire rod of deriving from the top of line mouth, this wire rod is positioned on the tangent line of volume core periphery, because the cross section of volume core is not circular, so this wire rod can shake the top of the line mouth of its derivation with rolling up between the core.So owing to need to prevent from making shaking of this wire rod to become acutely, thereby can't twine this wire rod at the volume core rapidly, thus be difficult to shorten its coiling time.
Following scheme is proposed: wound wire on the volume core of cross section circle in order to address this problem, obtain having the circular coil of ring cross-section, this circular coil is deformed into have the non-circular coil (for example, with reference to patent documentation 1) in other cross sections different from ring cross-section.According to this scheme, wound wire on the volume core of cross section circle, compare with the situation that in the cross section is wound wire on the non-circular volume core, owing to can between this line mouth top and volume core, not shake from the wire rod of line mouth top derivation, therefore can be than wire rod being wrapped on this volume core more quickly.And, make afterwards the circular coil distortion that obtains like this and obtain non-circular coil, by in the process of this distortion, carrying out the coiling for next circular coil, can expect significantly to shorten thus the manufacturing time of this coil.
Patent documentation 1: Japanese Unexamined Patent Application Publication 2008-511150 communique
But, obtain the operation of circular coil when wound wire on the volume core that carries out respectively in the cross section circle and make afterwards the circular coil distortion that obtains like this and when obtaining the operation of non-circular coil, there is following problems to be solved, that is: the extraction location of the lead-out wire on the resulting non-circular coil is uncertain, and this extraction location produces deviation.
That is, on using the volume core of coil winding machine in the cross section circle during wound wire, the lead-out wire of drawing from the circular coil that is made of this wire rod is always drawn from certain position with respect to the volume core.Then be to make this circular coil distortion, because this circular coil cross section is circular, so the position of circumferencial direction is difficult to determine no matter the arbitrary position of lead-out wire around circular coil all can make this circular coil distortion.When therefore making this circular coil distortion when the lead-out wire position in the uncertain circular coil, resulting non-circular coil, specifically draw and made in the situation of a plurality of non-circular coils in the arbitrary position around it of the lead-out wire with rectangle, Long Circle or oval prismatic coil, the lead-out wire of above-mentioned a plurality of non-circular coils can all not drawn from identical position.

(winding process)
In this operation, thereby wire rod 13 is wound into the circle acquisition is drawn lead-out wire 13a, 13b from the position of regulation circular coil 11.As shown in Figure 3 and Figure 4, this coiling utilizes coil winding machine 20 to carry out, papery bobbin 14 is embedded in its spools 24, and the end of the wire rod 13 that will derive from line mouth 26 is as the end of a thread wire rod 13, is the grips 28 that is arranged on the side around the disk 23 is controlled it.And, after this end of a thread wire rod 13 is directed to the groove 24c of the upper limb that is formed at large-diameter portion 24b, drives coiling and make its spool 24 rotations with motor 21, the wire rod 13 of deriving from the top of line mouth 26 is wound on the papery bobbin 14.And, when carrying out this coiling, by line mouth travel mechanism 27 line mouth 26 is moved back and forth along Z-direction, thereby wire rod 13 fitly is wrapped on this papery bobbin 14.After making the wire rod 13 coiling regulation number of turns, to be directed to the groove 24c of the upper limb that is formed at large-diameter portion 24b from the wire rod 13 that line mouth 26 is derived, then, as the wire rod 13 of line tail, be that the grips 29 that is arranged on the opposing party around the disk 23 is controlled it.So wire rod 13 is wound on the papery bobbin 14 of tubular, thereby around papery bobbin 14, forms circular coil 11.
Wherein, when the insulating coating of wire rod 13 during for material bonding after by heating melting and cooling, utilize 81 pairs of circular coils of air-heater 11 to spray hot blast, thereby the insulating coating that makes this wire rod 13 is melt bonded wire rod 13 is bonded together mutually, and this circular coil 11 is bonded on the papery bobbin 14, the shape of the circular coil 11 that consists of with the wire rod 13 that prevents by proper alignment after scatter.Then, the end of a thread wire rod 13 is taken off from grips 28, and near grips 29, line buttock line material 13 is cut off.So the lead-out wire 13a, the 13b that are made of this end of a thread wire rod 13 and line buttock line material 13 are housed among the groove 24c, thereby obtain the circular coil shown in Figure 4 11 that lead- out wire 13a, 13b always draw from certain assigned position.
(conveying operation)
In this operation, circular coil 11 is transported to forming machine 30 from coil winding machine 20.The conveying of this circular coil 11 is undertaken by supply unit 60, drives to carry to use motor 64 and operation with motor 71, makes to carry and moves along X-axis and Z axis with cylinder 72, and make this conveying be positioned at the top of coil winding machine 20 with cylinder 72.And, behind the mutual interval of a pair of front and back movable member 72a, the 72a that widen conveying usefulness cylinder 72, this conveying is descended with cylinder 72, be arranged on a pair of on this a pair of movable member 72a, 72a and control the both sides that sheet 74,74 is positioned at the X-direction of circular coil 11 such as Fig. 4 and shown in Figure 11 making.And by dwindling a pair of front and back movable member 72a, the mutual interval of 72a, thus with a pair ofly control sheet 74,74 mutual intervals narrow down.And in order not damage papery bobbin 14, and a pair of sheet 74,74 mutual intervals of controlling narrowed down to a pair of degree that contact-making surface 74a that sheet 74,74 the outer peripheral face with circular coil 11 contact is slightly less than the external diameter of this circular coil 11 of controlling, thus as shown in figure 12, from the both sides of X-direction therebetween circular coil 11 is controlled from its outside.At this moment, lead-out wire 13a, the 13b of circular coil 11 is contained in the groove 24c interior (Fig. 4) on the spool 24, therefore this lead-out wire 13a, 13b always can be remained on certain assigned position, and control from the outside to circular coil 11 by a pair of sheet 74,74 of controlling.
And, when controlling this circular coil 11, not shown air attractor, attract air via an end at a pair of airport 77 of controlling sheet 74, the 74 contact-making surface 74a upper sheds that contact with the outer peripheral face of circular coil 11, circular coil 11 is adsorbed on this circular coil 11 is carried out a pair of of clamping and controls on the sheet 74,74.Even a pair ofly thus control sheet 74,74 mutual opposed contact-making surface 74a are the degree that is slightly less than the external diameter of this circular coil 11, also can control effectively this circular coil 11 by a pair of sheet 74,74 of controlling.Then, drive operation with motor 71, make to carry with cylinder 72 and rise with circular coil 11, will control the circular coil 11 that sheet 74,74 controls and extract from spool 24 by a pair of.Then, drive to carry with motor 64 and operation with motor 71 both sides, make to carry and move towards forming machine 30 together with cylinder 72 and circular coil 11, a pair of parts 31,31 the below of expanding that makes that this circular coil 11 is arranged in forming machine 30.
(forming process)
In this operation, at least one pair of that will enter into these circular coil 11 inboards in forming machine 30 expands parts 31,31 interval is widened, and circular coil 11 is configured as non-circular coil 12.Circular coil 11 is arranged in a pair of parts 31,31 the below of expanding of forming machine 30, therefore a pair of parts 31,31 that expand enter circular coil 11 when inboard, undertaken by following method: by as shown in Figure 5 and Figure 6 make above-below direction rotating shaft 34 rotation with motor 36 up and down, above-below direction movable plate 35 is descended.At this moment, movable member 44 rises to utilize as shown in Figure 7 lifting to make up and down with motor 45, by the active force that expands usefulness spring 43, with a pair ofly move forward and backward parts 41,41 mutual intervals dwindle.When a pair ofly move forward and backward parts 41, when 41 mutual intervals dwindle, the a pair of parts 31,31 that expand also dwindle each other interval, a pair of when expanding parts 31,31 and descending with above-below direction movable plate 35 when what dwindled mutual interval, as shown in Figure 8, this a pair ofly expands the inboard that parts 31,31 its both sides enter into circular coil 11.
Then, with a pair ofly expand parts 31,31 interval is widened, and circular coil 11 is configured as non-circular coil 12.This is by carrying out up and down movable member 44 declines by lifting with motor 45, when movable member 44 descends up and down, a pair ofly move forward and backward parts 41,41 opposings expand with the active force of spring 43 and widen mutual interval, a pair of parts 31,31 that expand are also widened mutual interval with these a pair of parts 41,41 that move forward and backward.As shown in Figure 9, when a pair ofly expand parts 31, when 31 interval is widened, circular coil 11 is widened in X-direction from the inboard by this a pair of parts 31,31 that expand, and this circular coil 11 is shaped as by the arc sections 12a that forms semicircle shape and the non-circular coil 12 (Figure 19) with oval shape cross section that respectively the line part 12b of the end binding of this arc sections 12a consisted of.
When the interval that expands parts 31 that will enter into these circular coil 11 inboards is widened, by expanding parts 31 and controlling the wire rod 13 that 74 pairs of sheets consist of circular coil 11 and carry out clamping.Such as Figure 11 and shown in Figure 12, the supply unit 60 in the present embodiment arranges between front and back movable member 72a and slide block 73a and controls with spring 76, this control with spring 76 so that a pair of sheet 74,74 of controlling with this slide block 73a mode application of force close to each other.Therefore as shown in Figure 9, a pair ofly expand that parts 31,31 are widened its interval and when this circular coil 11 widened from the inboard along X-direction when what enter into circular coil 11 inboards, a pair of sheet 74,74 of controlling is also resisted and is controlled the state that contact with the outer peripheral face with this circular coil 11 with the active force of spring 76 and mutually expand.Therefore only by widening the interval that expands parts 31, this controls sheet 74 just can carry out clamping to the wire rod 13 that consists of circular coil 11 with expanding parts 31.
Wherein, circular coil 11 is transported to a pair of sheet 74,74 of controlling of this forming machine 30, lead-out wire 13a, the 13a of circular coil 11 always remained on the position of regulation, and control from the outside to circular coil 11, when being shaped, also with expanding parts 31 wire rod 13 that consists of circular coil 11 is carried out clamping, therefore wire rod 13 can not controlled sheet 74 with respect to this and moved, and can not change take this position of controlling lead-out wire 13a, the 13b of sheet 74 in the circular coil 11 of benchmark in this forming process.So such as Fig. 9, Figure 15 and shown in Figure 19, even at this circular coil 11 through being shaped and becoming in the situation of oblong non-circular coil 12, control sheet 74 take this and also can not change as the position of lead-out wire 13a, the 13b of benchmark.Therefore in the manufacturing installation and manufacture method thereof of non-circular coil 12 of the present invention, always can obtain the non-circular coil 12 that lead- out wire 13a, 13b draw from the position of regulation.
Widen a pair of when expanding parts 31,31 interval and circular coil 11 being configured as non-circular coil 12 or afterwards, contact component 86 intersected with the moving direction that expands parts 31 and contact with non-circular coil 12 from the outside of non-circular coil 12.The contact of this contact component 86 in the present embodiment, illustrates the situation that contact component 86 is contacted with it by carrying out such as Figure 13 and contact mechanism 85 shown in Figure 14.Therefore a pair ofly expand parts 31,31 interval and after circular coil 11 is configured as non-circular coil 12 widening, conveying in the supply unit 60 is widened with a pair of sheet 74,74 of controlling with the mutual interval of a pair of front and back movable member 72a, the 72a of cylinder 72, as shown in figure 11, remove this and a pair ofly control controlling of sheet 74,74 pairs of non-circular coils 12.At this moment, stop the air attractor, remove non-circular coil 12 to the absorption of controlling sheet 74.Then keep a pair ofly expanding parts 31,31 interval with what circular coil 11 was configured as non-circular coil 12, and by using up and down motor 36, make 34 rotations of above-below direction rotating shaft, and above-below direction movable plate 35 is risen with this non-circular coil 12.Then, a pair of sheet 74,74 of controlling of controlling of having removed non-circular coil 12 moves towards coil winding machine 20, enters the standby condition that the next circular coil 11 of being made by this coil winding machine 20 is controlled.
Make non-circular coil 12 with a pair of expand parts 31,31 and rise after, the turnover axle 92a that presses with cylinder 92 in the contact mechanism 85 is given prominence to, level board 91 is moved, and the jag of the level board 91 after this is moved is positioned at a pair of parts 31,31 the below of expanding.In two movable table 93,93 of the jag that is arranged on level board 91, a pair of parts that expand from Y direction clamping forming machine 30.And, outstanding by the turnover axle 94a that makes Miniature cylinder 94 as shown in figure 16, thus contact component 86 and the moving direction that expands parts 31 are intersected, and contact with this non-circular coil 12 from the outside of non-circular coil 12.Wherein, the amount of its contact is adjusted in advance by mircrometer gauge 96 (Figure 13 and Figure 14).
Wherein, when the insulating coating of wire rod 13 during for material bonding after by heating melting and cooling, when circular coil 11 is configured as non-circular coil 12 and when contact component 86 is contacted with this non-circular coil 12, spray hot blast by air-heater 81 to this non-circular coil 12, make the insulating coating of this wire rod 13 again melt bonded, the wire rod 13 that consists of non-circular coil 12 is again mutually bonding, and this non-circular coil 12 is bonded on the papery bobbin 14.Like this by contact component 86 is contacted with non-circular coil 12, the wire rod 13 of line part 12b in this non-circular coil 12 is alignd as the crow flies, the wire rod 13 of this straight alignment is bonding each other, thus prevent situation such as the line part 12b bending in the non-circular coil 12.Therefore contact component 86 can not make the line part 12b in the non-circular coil 12 crooked to the inside.
Then, the amount of these contact component 86 contacts can be adjusted by mircrometer gauge 96, therefore just can access the line part 12b with anticipated shape by the amount of adjusting this contact.In addition, in the situation that this non-circular coil 12 is made of the wire rod 13 that is wound on the papery bobbin 14, the non-circular coil 12 that the wire rod 13 by this straight alignment can be consisted of is bonded on this papery bobbin 14, therefore can eliminate the papery bobbin 14 and the dislocation between the non-circular coil 12 that produce because of shaping, so can prevent that this non-circular coil 12 from peeling off from papery bobbin 14.The shape that can prevent thus non-circular coil 12 after the situation of scattering, obtain the non-circular coil 12 that the lead-out wire 13a, the 13b that are made of the end of a thread wire rod 13 and line buttock line material 13 shown in Figure 19 (b) always draw from certain assigned position.
Resulting non-circular coil 12 descends with a pair of parts 31,31 (Fig. 5 and Fig. 6) that expand afterwards, dwindles this a pair of parts 31, interval of 31 of expanding, and non-circular coil 12 is taken off from this forming machine 30.At this moment, by taking out with cylinder 98, make to take out with the non-circular coil 12 of pawl 97 after descending and move, make this taking-up be positioned at the upside of non-circular coil 12 with pawl 97.Under this state, dwindle a pair of parts 31,31 the interval of expanding, a pair of parts 31,31 that expand are further risen.At this moment, even non-circular coil 12 cards hang over a pair of expanding on the parts 31,31, this non-circular coil 12 also can contact with pawl 97 with taking-up, thereby prevents that it from rising with a pair of parts 31,31 that expand.Can effectively non-circular coil 12 be extracted from a pair of parts 31 that expand thus.Then expand that parts 31 are pulled out and the non-circular coil 12 that falls is transferred the outside of catching and be discharged to this device 10 with 99 from a pair of, take out to take out with pawl 97 with cylinder 98 and again be withdrawn near the mounting panel 32.Finish thus a series of manufacturings of a non-circular coil 12, and begin the manufacturing of next non-circular coil.
Wherein, in the above-described embodiment, situation when contact component 86 is contacted with this non-circular coil 12 is illustrated, but also can form: as shown in figure 18, when circular coil 11 is configured as non-circular coil 12, contact component 86 is contacted with this non-circular coil 12.Even in this case, contact component 86 also can make this non-circular coil 12 contact with papery bobbin 14 and be bonding, thereby prevents that this non-circular coil 12 from peeling off from papery bobbin 14.
In addition, in the above-described embodiment, the coil winding machine 20 that obtains circular coil 11 by wound skein product 13 on papery bobbin 14 is illustrated, but circular coil 11 is not limited to be made of the wire rod 13 that is wound on the papery bobbin 14, also can be the so-called exoskeletal coil that does not use papery bobbin 14.In addition, even when using bobbin 14, this bobbin 14 also is not limited to the papery bobbin, and can be resinous bobbin, obtain the bobbin that is consisted of by nonmagnetic film.Wherein, as the resinite bobbin, the resinite bobbin 14 of preference as being consisted of by polyimide film (trade name: Kapp is logical).
