Description
本發明係關於一種適合於三相交流發電機等旋轉電機中的定子之製造之線圈變形裝置及使用該線圈變形裝置之定子製造裝置、以及定子之製造方法。 The present invention relates to a coil deforming device suitable for manufacture of a stator in a rotating electrical machine such as a three-phase alternator, a stator manufacturing device using the same, and a method of manufacturing the stator.
以往,旋轉電機之定子具備:圓筒狀之定子鐵心,其具有呈放射狀排列且朝內徑方向突出之複數個齒(磁極)及於其間隔開口之複數個溝槽;以及定子線圈,其藉由將邊部收納於溝槽中而組裝於鐵心。關於定子線圈之組裝,已知有獨立於定子鐵心而預先製作定子線圈,並將定子線圈之邊部***定子鐵心之各溝槽中之方法。 Conventionally, a stator of a rotating electrical machine includes a cylindrical stator core having a plurality of teeth (magnetic poles) radially arranged and protruding in an inner diameter direction, and a plurality of grooves opened at intervals therebetween; and a stator coil The core is assembled by accommodating the side portion in the groove. Regarding the assembly of the stator coil, a method of preliminarily making a stator coil independently of the stator core and inserting a side portion of the stator coil into each groove of the stator core is known.
作為定子之製造方法,例如有JP2007-166850A或JP2011-229285A所揭示者。於該等文獻所揭示之定子之製造方法中,係使用於外周形成有與定子鐵心之溝槽對應之保持溝槽群之圓柱狀插通夾具,將預先已捲繞之複數個線圈之一對邊部分別***至保持溝槽群中,使各線圈沿插通夾具之圓周而排列。又,將插通夾具***至定子鐵心之內周,並進行定位,以使保持溝槽與定子鐵心之對應之槽整合之後,將越朝向前端 則寬度變得越窄之板狀之推動件自前端***對應之各保持溝槽。被***保持溝槽之各線圈之一對邊部向外徑側被推出,從而***至定子鐵心之對應之溝槽中。 As a manufacturing method of a stator, the one disclosed by JP2007-166850A or JP2011-229285A is mentioned, for example. In the method for manufacturing a stator disclosed in the above documents, a cylindrical insertion jig having a groove group corresponding to a groove of a stator core is formed on the outer circumference, and one of a plurality of coils which have been wound in advance is used. The side portions are respectively inserted into the holding groove group, and the respective coils are arranged along the circumference of the insertion jig. Further, the insertion jig is inserted into the inner circumference of the stator core, and is positioned so that the groove of the plate-like pusher becomes narrower toward the front end after the groove is integrated with the groove corresponding to the stator core. The front end is inserted into each of the corresponding retaining grooves. One of the coils inserted into the holding groove is pushed out toward the outer diameter side to be inserted into the corresponding groove of the stator core.
此處,對於獨立於定子鐵心而預先製作之定子線圈,可藉由於卷芯上捲繞線材而獲得。上述方法中所用之線圈為軌道狀,其具有插通至保持溝槽之彼此平行之一對邊部、及將該一對邊部中之兩端部連結成圓弧狀之線圈尾端部。 Here, the stator coil which is prepared in advance independently of the stator core can be obtained by winding the wire on the winding core. The coil used in the above method has a rail shape, and has a pair of side portions that are inserted into the holding grooves in parallel with each other, and a coil end portion that connects both end portions of the pair of side portions in an arc shape.
即,預先製作之定子線圈係進行所謂之整齊捲繞,從而於其積層方向變長之筒狀線圈,該整齊捲繞係以於捲繞成軌道狀之卷線上沿軸方向堆積新的軌道狀卷線之方式,將線材呈螺旋狀而無間隙地捲繞至卷芯。 In other words, the stator coil which is prepared in advance is a cylindrical coil which is so-called neatly wound and which is elongated in the laminating direction, and which is stacked in a track-like winding line to form a new rail shape in the axial direction. In the manner of winding the wire, the wire is spirally wound to the core without a gap.
於圓柱狀插通夾具之周圍所形成之保持溝槽群係對應於定子鐵心之溝槽而形成。因此,保持溝槽群係以呈自其周圍朝向中央之放射狀之方式形成,沿周方向鄰接之保持溝槽並非彼此平行。 The group of holding grooves formed around the cylindrical insertion jig are formed corresponding to the grooves of the stator core. Therefore, the group of the holding grooves is formed in a radial shape from the periphery toward the center, and the holding grooves adjacent in the circumferential direction are not parallel to each other.
相對於此,將軌道狀卷線進行堆積而成為軸方向較長之筒狀線圈之各邊部,由於係將線材沿卷軸方向予以積層,因此於該卷軸方向上成為彼此平行。 On the other hand, the rail-shaped winding wires are stacked to form the respective side portions of the cylindrical coil having a long axial direction. Since the wires are laminated in the direction of the reel, they are parallel to each other in the direction of the reel.
因此,上述習知之製造方法中,線材係沿卷軸方向積層,為了將沿積層方向彼此平行地形成之各邊部***至放射狀之保持溝槽中,若不使彼此平行地形成之各邊部變形為可***至保持溝槽之後,便無法***保持溝槽中。於該變形時,若各邊部之線材失去整齊性,則有難以將各邊 部***保持溝槽中之問題。 Therefore, in the above-described conventional manufacturing method, the wires are laminated in the direction of the reel, and in order to insert the side portions formed in parallel with each other in the lamination direction into the radial holding grooves, the sides which are formed in parallel with each other are not formed. After being deformed to be inserted into the retaining groove, it cannot be inserted into the retaining groove. At the time of this deformation, if the wires of the respective side portions lose the uniformity, there is a problem that it is difficult to insert the respective side portions into the holding grooves.
並且,若線圈中之各邊部之線材失去整齊性,則難以提高卷線之分層因數(lamination factor)。因而,存在無法謀求發電機或馬達之高效率化或小型化等之問題。 Further, if the wire of each side portion of the coil loses the uniformity, it is difficult to increase the lamination factor of the winding. Therefore, there is a problem in that it is impossible to increase the efficiency or size of the generator or the motor.
本發明之目的在於提供一種線圈變形裝置,不會使捲繞整齊之線圈之各邊部之線材失去整齊性而可使其變形。 It is an object of the present invention to provide a coil deforming device which can be deformed without losing the uniformity of the wires of the respective sides of the wound coils.

如圖1所示,定子製造裝置9具備捲線機20,該捲線機20捲繞線材8以製作定子線圈12(圖15~圖17)。本實施形態之捲線機20適合於製作於下述情形時有效之定子線圈12,即,如圖15所示,使彼此平行之一對邊部13a、14a分別插通至定子鐵心11之2個溝槽11b。 As shown in Fig. 1, the stator manufacturing apparatus 9 includes a winding machine 20 that winds a wire 8 to form a stator coil 12 (Figs. 15 to 17). The winding machine 20 of the present embodiment is suitable for manufacturing the stator coil 12 which is effective in the case where two parallel side portions 13a and 14a are respectively inserted into the stator core 11 as shown in Fig. 15 Groove 11b.
定子線圈12雖為形成1個卷線層者,但為使其等之邊部13a、14a分別插通至鄰接之2個溝槽11b者。即,捲線機20構成為可製作定子線圈12,該定子線圈12由沿軸方向較長之筒狀之內線圈13(圖5);及自外側隔開既定間隔t2(圖6)而包圍內線圈13之外線圈14(圖6)構成。 The stator coil 12 is formed by forming one winding layer, but the side portions 13a and 14a are inserted into the adjacent two grooves 11b. That is, the winding machine 20 is configured to be a stator coil 12 which is formed by a cylindrical inner coil 13 (Fig. 5) which is long in the axial direction, and is surrounded by a predetermined interval t2 (Fig. 6) from the outside. The coil 14 is formed by a coil 14 (Fig. 6).
線材8為包覆導線,且為剖面呈圓形之所謂圓線。再者,線材8亦可為剖面呈方形之所謂方線。又,捲線機20係設為捲繞單一線材8者進行說明,但亦可為以並列之狀態捲繞複數根線材8者。 The wire 8 is a covered wire and is a so-called round wire having a circular cross section. Furthermore, the wire 8 may also be a so-called square wire having a square cross section. In addition, the winding machine 20 is described as a single wire 8 to be wound, but a plurality of wires 8 may be wound in a state of being aligned.
如圖4所示,捲線機20具有:內卷芯24,其藉由旋轉機構21而旋轉,用於藉由所捲繞之線材8獲得軌道狀之內線圈13(圖5);以及外卷芯25,其可包圍內卷芯24地構成,與內卷芯24一同旋轉,用於藉由所捲繞之線材8獲得軌道狀之外線圈14(圖6)。 As shown in FIG. 4, the winding machine 20 has an inner winding core 24 which is rotated by a rotating mechanism 21 for obtaining a track-like inner coil 13 (Fig. 5) by the wound wire 8; The core 25, which may surround the inner core 24, rotates together with the inner core 24 for obtaining a track-like outer coil 14 by the wound wire 8 (Fig. 6).
內卷芯24具有內卷線軸24a,該內卷線軸24a分別安裝於 藉由旋轉機構21而旋轉之一對盤繞柱22、23前端之旋轉半徑外側。旋轉機構21構成為,如圖5所示,在位於以彼此平行之狀態沿鉛垂方向延伸之一對盤繞柱22、23之中央的鉛垂軸C之周圍,可使一對盤繞柱22、23以彼此平行之狀態旋轉。於其中一個盤繞柱22與另一個盤繞柱23各自之下部,於旋轉半徑之外側分別安裝有盤繞線材8之內卷線軸24a。 The inner winding core 24 has an inner bobbin 24a which is attached to the outer side of the radius of rotation of one of the pair of coiled columns 22, 23 by the rotation mechanism 21, respectively. The rotating mechanism 21 is configured such that a pair of coiled columns 22 can be formed around the vertical axis C of one of the coiled columns 22 and 23 extending in the vertical direction in a state parallel to each other as shown in FIG. 23 rotates in a state parallel to each other. The inner bobbin 24a of the coiled wire 8 is mounted on the outer side of one of the coiled columns 22 and the other of the coiled columns 23, respectively, on the outer side of the radius of rotation.
如圖5所示,盤繞線材8之內卷線軸24a之外表面係朝旋轉半徑外側鼓出地形成,以使所盤繞之線材8平緩地翻折而形成大致圓弧狀。因此,當使其中一個盤繞柱22及另一個盤繞柱23與內卷芯24一同旋轉而使線材8捲繞於內卷芯24時,盤繞於其中一個盤繞柱22及另一個盤繞柱23各自之內卷線軸24a而彎曲成圓弧狀之線材8形成線圈尾端部13b。又,掛設於其中一個盤繞柱22與另一個盤繞柱23之間之線材8形成邊部13a。如此,形成軌道狀之內線圈13。 As shown in Fig. 5, the outer surface of the inner bobbin 24a of the coiled wire 8 is formed to bulge outwardly of the radius of rotation so that the coiled wire 8 is gently folded to form a substantially arc shape. Therefore, when one of the coiled columns 22 and the other coiled column 23 are rotated together with the inner winding core 24 to wind the wire 8 around the inner winding core 24, it is wound around one of the coiled columns 22 and the other of the coiled columns 23 The wire 8 bent in an arc shape by winding the bobbin 24a forms the coil end portion 13b. Further, the wire 8 hooked between one of the coiled columns 22 and the other of the coiled columns 23 forms a side portion 13a. In this way, the inner coil 13 in the shape of a rail is formed.
另一方面,用於獲得軌道狀之外線圈14(圖6)之外卷芯25具有外卷線軸25a,該外卷線軸25a構成為可隔開既定間隔t2而覆蓋內卷線軸24a。如圖4所示,本實施形態中,外卷芯25係可於一對盤繞柱22、23上移動地設置。如圖6所示,外卷線軸25a於下降狀態下,處於自旋轉半徑外側覆蓋內卷芯24中之內卷線軸24a之卷位置。如圖4及圖5所示,外卷線軸25a於上升狀態下,處於將內卷線軸24a之旋轉半徑外側開放之待機位置。外卷線軸25a構成為,可於卷位置與待機位置之間往復移動。 On the other hand, the core 25 for obtaining the outer coil 14 (Fig. 6) has an outer bobbin 25a which is configured to cover the inner bobbin 24a at a predetermined interval t2. As shown in Fig. 4, in the present embodiment, the outer core 25 is movably provided on the pair of coiled columns 22, 23. As shown in Fig. 6, the outer bobbin 25a is in the lowered state, and covers the winding position of the inner bobbin 24a in the inner core 24 on the outer side of the self-rotation radius. As shown in FIGS. 4 and 5, the outer bobbin 25a is in a raised position, and is in a standby position in which the outer radius of the inner bobbin 24a is opened outside. The outer bobbin 25a is configured to reciprocate between a winding position and a standby position.
如圖5及圖6所示,外卷線軸25a係以其內面覆蓋盤繞於內卷線軸24a之線材8之方式彎曲地形成。又,外卷線軸25a之線材8盤繞之外表面係朝旋轉半徑外側鼓出地形成,以使所盤繞之線材8平緩地翻折而 形成大致圓弧狀。 As shown in FIGS. 5 and 6, the outer bobbin 25a is formed to be curved so that the inner surface thereof covers the wire 8 wound around the inner bobbin 24a. Further, the outer surface of the wire 8 of the outer bobbin 25a is formed so as to bulge outwardly from the outer side of the radius of rotation so that the coiled wire 8 is gently folded to form a substantially arc shape.
因此,如圖6所示,當使線材8捲繞至卷位置處的各外卷線軸25a時,盤繞於外卷線軸25a而彎曲成圓弧狀之線材8形成線圈尾端部14b。又,掛設於其中一個盤繞柱22與另一個盤繞柱23之間之線材8形成邊部14a。如此,形成軌道狀之外線圈14。 Therefore, as shown in Fig. 6, when the wire 8 is wound around the outer bobbin 25a at the winding position, the wire 8 which is wound around the outer bobbin 25a and bent into an arc shape forms the stitch end portion 14b. Further, the wire 8 hooked between one of the coiled columns 22 and the other of the coiled columns 23 forms a side portion 14a. In this way, the coil 14 is formed in a track shape.
如此,捲線機20構成為可製作定子線圈12,該定子線圈12由俯視呈軌道狀之筒狀之內線圈13;及自外側隔開既定間隔t2而包圍內線圈13之外線圈14構成。 In this way, the winding machine 20 is configured to be a stator coil 12 which is formed by a cylindrical inner coil 13 having a rail shape in plan view, and a coil 14 which surrounds the inner coil 13 with a predetermined interval t2 from the outside.

<線圈製作步驟> <Coil fabrication step>
於線圈製作步驟中,捲繞線材8而製作具有彼此平行之一對邊部13a、14a之定子線圈12。 In the coil forming step, the wire 8 is wound to form the stator coil 12 having the pair of side portions 13a, 14a parallel to each other.
本實施形態中,捲線機20製作如圖6所示般,由內線圈13及自外側包圍內線圈13之外線圈14構成之定子線圈12。因而,線圈製作步驟具有製作內線圈13之內卷步驟與製作外線圈14之外卷步驟,以製作由內線圈13與外線圈14構成之定子線圈12。 In the present embodiment, the winding machine 20 is formed by the inner coil 13 and the stator coil 12 including the coil 14 other than the inner coil 13 from the outside as shown in Fig. 6 . Therefore, the coil manufacturing step has an in-volume step of fabricating the inner coil 13 and a winding step of fabricating the outer coil 14, to fabricate the stator coil 12 composed of the inner coil 13 and the outer coil 14.
具體而言,於內卷步驟中,如圖5所示,藉由旋轉機構21(圖4)使內卷芯24旋轉,以將自線材放出構件26放出之線材8捲繞至內卷芯24之周圍而製作內線圈13。與內卷芯24之旋轉一同,使線材放出構件26朝內卷芯24之旋轉軸方向移動,以使自線材放出構件26放出之線材8呈螺旋狀而整齊地捲繞至內卷芯24。 Specifically, in the involution step, as shown in FIG. 5, the inner winding core 24 is rotated by the rotating mechanism 21 (FIG. 4) to wind the wire 8 discharged from the wire discharging member 26 to the inner winding core 24 The inner coil 13 is formed around it. Together with the rotation of the inner winding core 24, the wire discharging member 26 is moved in the direction of the rotation axis of the inner winding core 24 so that the wire 8 discharged from the wire discharging member 26 is spirally wound and wound neatly to the inner winding core 24.
如此,於內卷步驟中,製作出軌道狀之內線圈13,該軌道狀之內線圈13具有:線圈尾端部13b,其由盤繞於內卷線軸24a之線材8構成;以及邊部13a,其由掛設於一對盤繞柱22、23之間之線材8構成。 In the inner winding step, the inner coil 13 is formed in a track shape, and the inner coil 13 has a coil end portion 13b composed of a wire 8 wound around the inner bobbin 24a, and a side portion 13a. It consists of a wire 8 that is suspended between a pair of coiled columns 22, 23.
接下來,藉由外卷芯25包圍內線圈13及內卷芯24。本實施形態中,使用使外卷芯25可移動地構成之捲線機20。因而,本實施形態中,使外卷芯25自圖4所示之待機位置朝下方移動,從而如圖6所示,使其移動至包圍內線圈13之包圍位置。如此,藉由外卷線軸25a覆蓋內線圈13之線圈尾端部13b,隨後進行外卷步驟。 Next, the inner coil 13 and the inner winding core 24 are surrounded by the outer winding core 25. In the present embodiment, the winding machine 20 configured to movably move the outer core 25 is used. Therefore, in the present embodiment, the outer winding core 25 is moved downward from the standby position shown in Fig. 4, and as shown in Fig. 6, it is moved to the surrounding position surrounding the inner coil 13. Thus, the coil end portion 13b of the inner coil 13 is covered by the outer bobbin 25a, and then the outer winding step is performed.
於外卷步驟中,使外卷芯25與內卷芯24一同旋轉,以將自線材放出構件26放出之線材8捲繞至外卷芯25之周圍而製作外線圈14。3軸移動機構27使線材放出構件26與外卷芯25之旋轉一同朝外卷芯25之旋轉軸方向移動,使自線材放出構件26放出之線材8呈螺旋狀而整齊地捲繞至外卷芯24。 In the outer winding step, the outer winding core 25 is rotated together with the inner winding core 24 to wind the wire 8 discharged from the wire discharging member 26 around the outer winding core 25 to form the outer coil 14. The three-axis moving mechanism 27 The wire releasing member 26 is moved in the direction of the rotation axis of the outer winding core 25 together with the rotation of the outer winding core 25, and the wire 8 discharged from the wire discharging member 26 is spirally wound and wound to the outer winding core 24 in a neat manner.
如此,如圖6所示,於外卷步驟中,製作出軌道狀之外線圈14,該軌道狀之外線圈14具有:線圈尾端部14b,其由盤繞於外卷線軸25a之線材8構成;以及邊部14a,其由掛設於一對盤繞柱22、23之間之線材8構成。 Thus, as shown in Fig. 6, in the outer winding step, a track-shaped outer coil 14 having a coil tail end portion 14b composed of a wire 8 wound around the outer winding bobbin 25a is formed. And the side portion 14a, which is composed of a wire 8 that is hung between the pair of coiled columns 22, 23.
此處,外卷芯25中的外卷線軸25a係以自外側覆蓋內線圈13之線圈尾端部13b之方式構成,因此由盤繞於外卷線軸25a之線材8構成之外線圈14成為自外側包圍內線圈13之大小。內線圈13與外線圈14各自之邊部13a、14a中的間隔t2,係與該等邊部13a、14a隨後將***之、定子鐵心11之鄰接之溝槽11b之周方向之間隔t1(圖10)一致。 Here, the outer bobbin 25a in the outer core 25 is configured to cover the coil end portion 13b of the inner coil 13 from the outside, and thus the outer coil 14 is formed by the wire 8 wound around the outer bobbin 25a. The size of the inner coil 13 is enclosed. The interval t2 in the side portions 13a, 14a of the inner coil 13 and the outer coil 14 is the interval t1 between the circumferential direction of the adjacent groove 11b of the stator core 11 to which the equilateral portions 13a, 14a are to be inserted later (Fig. 10) Consistent.
<交接步驟> <Handover Step>
於該步驟中,使一對交接夾具32、32上分別形成之狹縫32a、32b平行,並使一對邊部13a、14a以彼此平行之狀態分別***至狹縫32a、32b 中。 In this step, the slits 32a and 32b formed in the pair of transfer jigs 32 and 32, respectively, are parallel, and the pair of side portions 13a and 14a are inserted into the slits 32a and 32b in parallel with each other.
本實施形態中,於線圈變形裝置31中的旋轉機構33中,如圖6所示,使一對交接夾具32、32彼此平行,並藉由分離/靠近機構34,使一對交接夾具32、32彼此之間隔與定子線圈12中的邊部13a、14a間之間隔一致。 In the present embodiment, in the rotation mechanism 33 of the coil deforming device 31, as shown in FIG. 6, the pair of transfer jigs 32, 32 are parallel to each other, and the pair of transfer jigs 32 are separated by the separation/proximity mechanism 34, The interval between 32 is the same as the interval between the side portions 13a, 14a in the stator coil 12.
隨後,藉由移動機構40之3軸移動機構41使線圈變形裝置31移動,從而如圖7所示,使一對邊部13a、14a以彼此平行之狀態分別***至一對交接夾具32、32上分別形成之狹縫32a、32b內。 Subsequently, the coil deforming means 31 is moved by the three-axis moving mechanism 41 of the moving mechanism 40, so that the pair of side portions 13a, 14a are inserted into the pair of transfer jigs 32, 32, respectively, in parallel with each other as shown in FIG. The slits 32a, 32b are formed in the upper portions.
本實施形態中,於卷線步驟中,獲得由內線圈13及外線圈14構成之定子線圈12。因此,於交接步驟中,使用分別形成有供內線圈13之邊部13a***之內狹縫32a、及供外線圈14之邊部14a***之外狹縫32b兩者之一對交接夾具32、32。內線圈13之邊部13a與外線圈14之邊部14a係以彼此平行之狀態***至內狹縫32a與外狹縫32b。 In the present embodiment, the stator coil 12 composed of the inner coil 13 and the outer coil 14 is obtained in the winding step. Therefore, in the transfer step, the inner slits 32a into which the inner portions 13a of the inner coils 13 are respectively inserted, and the side portions 14a from which the outer coils 14 are inserted are inserted into the outer slits 32b, 32. The side portion 13a of the inner coil 13 and the side portion 14a of the outer coil 14 are inserted into the inner slit 32a and the outer slit 32b in a state of being parallel to each other.
又,線圈變形裝置31具備防止機構70,該防止機構70防止收納於狹縫32a、32b中之邊部13a、14a自狹縫32a、32b脫離。因此,在使一對邊部13a、14a以彼此平行之狀態分別***至一對交接夾具32、32之狹縫32a、32b之後,藉由防止機構70之致動器73(圖2)使軸構件71與鉤構件72一同旋轉,從而如圖7所示,使鉤構件72之覆蓋部72b進入切口32e。藉此,覆蓋部72b橫切狹縫32a、32b之入口側(圖10)。 Further, the coil deforming device 31 includes a preventing mechanism 70 that prevents the side portions 13a and 14a accommodated in the slits 32a and 32b from being separated from the slits 32a and 32b. Therefore, after the pair of side portions 13a, 14a are inserted into the slits 32a, 32b of the pair of the transfer jigs 32, 32, respectively, in parallel with each other, the shaft 73 of the mechanism 70 (Fig. 2) is prevented. The member 71 rotates together with the hook member 72, so that the covering portion 72b of the hook member 72 enters the slit 32e as shown in FIG. Thereby, the covering portion 72b crosses the entrance side of the slits 32a, 32b (Fig. 10).
如此,藉由覆蓋部72b,防止收納於狹縫32a、32b中之邊部13a、14a自該狹縫32a、32b脫出。 As described above, the covering portions 72b prevent the side portions 13a and 14a accommodated in the slits 32a and 32b from coming out of the slits 32a and 32b.
於此狀態下,移動機構40中的3軸移動機構41使線圈變形 裝置31與***有邊部13a、14a之定子線圈12一同進一步移動,使定子線圈12自內卷芯24及外卷芯25脫離。 In this state, the three-axis moving mechanism 41 in the moving mechanism 40 further moves the coil deforming device 31 together with the stator coil 12 into which the side portions 13a and 14a are inserted, so that the stator coil 12 is self-winding core 24 and outer core 25 Get rid of.
以下,具體說明使內線圈13與外線圈14自內卷芯24及外卷芯25脫離之流程。首先,將一對邊部13a、14a***至狹縫32a、32b,以維持該等之形狀。接下來,禁止自線材放出構件26放出新的線材8,並藉由未圖示之切斷裝置等,切斷自線材放出構件26延伸至外線圈14之線材8。藉此,使定子線圈12自線材放出構件26獨立。然後,使形狀得以維持之內線圈13與外線圈14與一對交接夾具32、32一同朝下方移動,以自一對盤繞柱22、23之開放之下端面朝下方抽出。 Hereinafter, the flow of separating the inner coil 13 and the outer coil 14 from the inner core 24 and the outer core 25 will be specifically described. First, a pair of side portions 13a, 14a are inserted into the slits 32a, 32b to maintain the shape. Next, it is prohibited to discharge the new wire 8 from the wire discharging member 26, and the wire 8 extending from the wire discharging member 26 to the outer coil 14 is cut by a cutting device or the like (not shown). Thereby, the stator coil 12 is made independent from the wire discharging member 26. Then, the inner coil 13 and the outer coil 14 which are maintained in shape are moved downward together with the pair of transfer jigs 32, 32 to be drawn downward from the open lower end faces of the pair of coiled columns 22, 23.
然後,藉由移動機構40,如圖1所示,使線圈變形裝置31與定子線圈12一同分離捲線機20。 Then, by the moving mechanism 40, as shown in FIG. 1, the coil deforming device 31 and the stator coil 12 are separated from the winding machine 20.
<線圈變形步驟> <Coil deformation step>
於此步驟中,使一對交接夾具32、32之其中任一者或兩者以與狹縫32a、32b之長度方向平行之旋轉軸32c為中心而旋轉。並且,使狹縫32a、32b跟***其中之邊部13a、14a一同,與供邊部13a、14a***之定子鐵心11之溝槽11b之角度α2一致。 In this step, either or both of the pair of delivery jigs 32 and 32 are rotated about the rotation axis 32c parallel to the longitudinal direction of the slits 32a and 32b. Further, the slits 32a and 32b are aligned with the side portions 13a and 14a inserted therein, and coincide with the angle α2 of the groove 11b of the stator core 11 into which the side portions 13a and 14a are inserted.
本實施形態中,分別驅動線圈變形裝置31中的為旋轉機構之一對電動馬達33、33,從而如圖8所示,使一對交接夾具32、32兩者以與狹縫32a、32b之長度方向平行之旋轉軸為中心,而如實線箭頭所示般旋轉。藉此,使一對交接夾具32、32與***至狹縫32a、32b內的邊部13a、14a一同變更至狹縫32a、32b之深度方向交叉之交叉位置。 In the present embodiment, one of the rotation means of the coil deforming means 31 is driven to the electric motors 33, 33, respectively, so that as shown in Fig. 8, both of the pair of transfer jigs 32, 32 are formed with the slits 32a, 32b. The axis of rotation parallel to the length direction is centered and rotates as indicated by the solid arrow. Thereby, the pair of delivery jigs 32 and 32 are changed together with the side portions 13a and 14a inserted into the slits 32a and 32b to the intersection positions where the slits 32a and 32b intersect in the depth direction.
如此,如圖10所示,使狹縫32a、32b之角度α1跟邊部13a、 14a一同,與定子鐵心11之欲***之溝槽11b之角度α2一致。如此,使***至狹縫32a、32b內的邊部13a、14a之積層方向,跟與溝槽11b之角度α2相應之溝槽11b之傾斜方向一致。 Thus, as shown in Fig. 10, the angle α1 of the slits 32a and 32b coincides with the edge portions 13a and 14a, and coincides with the angle α2 of the groove 11b of the stator core 11 to be inserted. In this manner, the lamination direction of the side portions 13a and 14a inserted into the slits 32a and 32b coincides with the inclination direction of the groove 11b corresponding to the angle α2 of the groove 11b.
<夾具分離/靠近步驟> <Jig separation/proximity step>
於此步驟中,如圖10所示,使一對交接夾具32、32中的狹縫32a、32b之開口部間之間隔d1、d2,與***至狹縫32a、32b內的一對邊部13a、14a欲***之溝槽11b之間隔D1、D2一致。 In this step, as shown in FIG. 10, the intervals d1 and d2 between the openings of the slits 32a and 32b of the pair of transfer jigs 32 and 32 and the pair of sides inserted into the slits 32a and 32b are formed. The intervals D1 and D2 of the grooves 11b to be inserted 13a, 14a are the same.
本實施形態中,於狹縫32a、32b之深度方向設有一對交接夾具32、32中的L型托架32d。因而,藉由線圈變形裝置31之分離/靠近機構34,使設有一對交接夾具32、32之一對電動馬達33之間隔靠近,從而如圖8之虛線箭頭所示般使一對交接夾具32、32彼此接近。如此,如圖10所示,將狹縫32a、32b之開口部間之間隔d1、d2變更為,與***至狹縫32a、32b內的一對邊部13a、14a欲***之溝槽11b之間隔D1、D2一致。 In the present embodiment, the L-shaped brackets 32d of the pair of delivery jigs 32 and 32 are provided in the depth direction of the slits 32a and 32b. Therefore, by the separation/adjacent mechanism 34 of the coil deforming device 31, the distance between one of the pair of the transfer jigs 32, 32 is set to be close to the electric motor 33, so that the pair of transfer jigs 32 are as shown by the dotted arrows in FIG. 32 are close to each other. Thus, as shown in Fig. 10, the intervals d1 and d2 between the openings of the slits 32a and 32b are changed to the grooves 11b to be inserted into the pair of side portions 13a and 14a inserted into the slits 32a and 32b. The intervals D1 and D2 are the same.
再者,該夾具分離/靠近步驟較佳為與線圈變形步驟同時進行。 Furthermore, the jig separation/proximity step is preferably performed simultaneously with the coil deformation step.
藉由線圈變形步驟與夾具分離/靠近步驟,定子線圈12如圖10所示,其邊部13a、14a於捲繞方向上間隔不同(圖中為八字形)。然而,由於線圈12之各邊部13a、14a分別***於狹縫32a、32b內,因此如圖8所示,主要是線圈尾端部13b、14b分別發生變形。因此,藉由使用線圈變形裝置31,當使定子線圈12變形時,可防止各邊部13a、14a之線材8之整齊性受損。 By the coil deformation step and the jig separation/adjacent step, the stator coil 12 has different sides (13-shaped in the figure) in the winding direction as shown in Fig. 10 . However, since the respective side portions 13a and 14a of the coil 12 are inserted into the slits 32a and 32b, respectively, as shown in Fig. 8, the coil end portions 13b and 14b are mainly deformed. Therefore, by using the coil deforming device 31, when the stator coil 12 is deformed, the alignment of the wires 8 of the respective side portions 13a, 14a can be prevented from being impaired.
<夾具***步驟> <Jig insertion step>
於此步驟中,使一對交接夾具32、32進入定子鐵心11內,從而如圖11所示,使狹縫32a、32b之開口部與溝槽11b之開口部對向。 In this step, the pair of delivery jigs 32 and 32 are placed in the stator core 11, and as shown in Fig. 11, the openings of the slits 32a and 32b are opposed to the opening of the groove 11b.
具體而言,夾具***步驟係藉由定子製造裝置9中的移動機構40來進行。藉由3軸移動機構41及鐵心移動機構51,使線圈變形裝置31及定子鐵心11之其中任一者或兩者移動,從而如圖9及圖10所示,使一對交接夾具32、32進入搭載於水平基板16之定子鐵心11。 Specifically, the jig insertion step is performed by the moving mechanism 40 in the stator manufacturing device 9. The three-axis moving mechanism 41 and the core moving mechanism 51 move either or both of the coil deforming device 31 and the stator core 11 to form a pair of transfer jigs 32 and 32 as shown in FIGS. 9 and 10 . The stator core 11 mounted on the horizontal substrate 16 is entered.
於如此般一對交接夾具32、32進入定子鐵心11內之***位置,3軸移動機構41使線圈變形裝置31進一步移動,從而如圖11所示,使狹縫32a、32b之開口部與一對邊部13a、14a欲***之溝槽11b之開口部對向。 When the pair of transfer jigs 32 and 32 enter the insertion position in the stator core 11, the three-axis moving mechanism 41 further moves the coil deforming device 31, thereby opening the openings of the slits 32a and 32b as shown in FIG. The opening portions of the grooves 11b to be inserted into the side portions 13a and 14a are opposed to each other.
隨後,驅動防止機構70中的致動器73以使軸構件71旋轉。藉此,使鉤構件72中的覆蓋部72b自切口32e脫離,以開放狹縫32a、32b之入口側。 Subsequently, the actuator 73 in the prevention mechanism 70 is driven to rotate the shaft member 71. Thereby, the covering portion 72b in the hook member 72 is detached from the slit 32e to open the inlet side of the slits 32a, 32b.
<邊部***步驟> <Edge insertion step>
於此步驟中,將***至狹縫32a、32b之定子線圈12之邊部13a、14a自狹縫32a、32b予以推出,以***至定子鐵心11之對應之溝槽11b內。 In this step, the side portions 13a, 14a of the stator coil 12 inserted into the slits 32a, 32b are pushed out from the slits 32a, 32b to be inserted into the corresponding grooves 11b of the stator core 11.
邊部***步驟係藉由邊部***機構61來進行。具體而言,如圖12所示,藉由使可動體64靠近水平基板16,從而將推動件62自前端***至搭載於水平基板16之定子鐵心11內所***之交接夾具32之狹縫32a、32b內。如此,將與***位置之交接夾具32之狹縫32a、32b對應地配置且越朝向前端則寬度變得越窄之板狀之推動件62,自前端***至對應之狹縫32a、32b內。進而,如圖13所示,將***至狹縫32a、32b內之定 子線圈11之邊部13a、14a自狹縫32a、32b予以推出,而分別***至對應之溝槽11b中。 The edge insertion step is performed by the edge insertion mechanism 61. Specifically, as shown in FIG. 12, by pushing the movable body 64 close to the horizontal substrate 16, the pusher 62 is inserted from the front end into the slit 32a of the transfer jig 32 inserted in the stator core 11 mounted on the horizontal substrate 16. Within 32b. In this manner, the plate-shaped pusher 62 which is disposed corresponding to the slits 32a and 32b of the delivery jig 32 at the insertion position and which has a narrower width toward the distal end is inserted into the corresponding slits 32a and 32b from the distal end. Further, as shown in Fig. 13, the side portions 13a, 14a of the stator coil 11 inserted into the slits 32a, 32b are pushed out from the slits 32a, 32b, and inserted into the corresponding grooves 11b.
此處,為便於理解本實施形態,參照圖18說明本發明之比較例。 Here, in order to facilitate the understanding of the present embodiment, a comparative example of the present invention will be described with reference to FIG.
於比較例之定子之製造方法中,如圖18所示,使用於外周形成有與定子鐵心2之溝槽2a對應之保持溝槽3a群的圓柱狀之插通夾具3。具體說明之,於比較例中,將預先捲繞之複數個線圈4之一對邊部4a、4b分別***至保持溝槽3a群中,使各線圈4沿插通夾具3之圓周而排列。然後,將插通夾具3***至定子鐵心2之內周,並進行定位,以使保持溝槽3a與定子鐵心2之對應之溝槽2a整合。隨後,將越朝向前端則寬度變得越窄之板狀之推動件5自前端***至對應之各保持溝槽3a,將***至保持溝槽3a中之各線圈4之一對邊部4a、4b推出至外徑側,以***至定子鐵心2之對應之溝槽2a內。 In the manufacturing method of the stator of the comparative example, as shown in FIG. 18, a cylindrical insertion jig 3 in which a group of holding grooves 3a corresponding to the grooves 2a of the stator core 2 are formed on the outer circumference is used. Specifically, in the comparative example, one of the plurality of coils 4 wound in advance, the pair of side portions 4a and 4b, is inserted into the group of the holding grooves 3a, and the coils 4 are arranged along the circumference of the insertion jig 3. Then, the insertion jig 3 is inserted into the inner circumference of the stator core 2, and positioning is performed so that the holding groove 3a is integrated with the corresponding groove 2a of the stator core 2. Subsequently, the plate-shaped pusher 5 whose width becomes narrower toward the front end is inserted from the front end into the corresponding holding grooves 3a, and is inserted into one of the side portions 4a of the respective coils 4 in the holding groove 3a, 4b is pushed out to the outer diameter side to be inserted into the corresponding groove 2a of the stator core 2.
此處,獨立於定子鐵心2而預先製作之定子線圈4,可藉由將線材捲繞於卷芯而獲得。比較例之定子線圈4為軌道狀,其具有:彼此平行之一對邊部4a、4b,其等插通至保持溝槽3a;以及線圈尾端部4c、4d,其等將一對邊部4a、4b中之兩端部連結呈圓弧狀。 Here, the stator coil 4 which is prepared in advance independently of the stator core 2 can be obtained by winding a wire around a winding core. The stator coil 4 of the comparative example has a rail shape and has: one pair of side portions 4a, 4b parallel to each other, which are inserted into the holding groove 3a, and the coil tail end portions 4c, 4d, which are a pair of sides The ends of 4a and 4b are connected in an arc shape.
即,預先製作之定子線圈4係進行所謂之整齊捲繞,從而於其積層方向上變長之筒狀線圈,該整齊捲繞係以於捲繞成軌道狀之卷線上沿軸方向堆積新的軌道狀卷線之方式,將線材呈螺旋狀而無間隙地捲繞至卷芯。 In other words, the stator coil 4 which is prepared in advance is a cylindrical coil which is so-called neatly wound and which is elongated in the laminating direction, and which is stacked in a track-like winding line and stacked in the axial direction. In the form of a track-like winding, the wire is spirally wound to the core without a gap.
如圖18所示,於圓柱狀插通夾具3之周圍所形成之保持溝 槽3a群為了形成為對應於定子鐵心2之溝槽2a,以自其周圍朝向中央之放射狀之方式形成。即,沿周方向鄰接之保持溝槽3a並非彼此平行。 As shown in Fig. 18, the group of the holding grooves 3a formed around the cylindrical insertion jig 3 is formed so as to be formed in a radial shape from the periphery toward the center of the groove 2a corresponding to the stator core 2. That is, the holding grooves 3a adjacent in the circumferential direction are not parallel to each other.
相對於此,將軌道狀卷線進行堆積而構成軸方向較長之筒狀之線圈4之各邊部4a、4b係將線材沿卷軸方向予以積層。藉此,各邊部4a、4b於該卷軸方向上為彼此平行者。 On the other hand, each of the side portions 4a and 4b of the coil 4 having a tubular shape in which the rail-shaped winding wires are stacked to form a long axial direction is laminated in the direction of the reel. Thereby, each of the side portions 4a, 4b is parallel to each other in the direction of the reel.
如此,比較例之定子之製造方法中,線材係沿卷軸方向積層,並將沿積層方向彼此平行地形成之各邊部4a、4b***至呈放射狀之保持溝槽3a中。因此,若不是於使彼此平行地形成之各邊部4a、4b變形為可***至保持溝槽3a之後,便無法***保持溝槽3a中。於變形時,若各邊部4a、4b之線材失去整齊性,則將難以***至保持溝槽3a中。 As described above, in the manufacturing method of the stator of the comparative example, the wires are laminated in the direction of the reel, and the side portions 4a, 4b formed in parallel with each other in the lamination direction are inserted into the radially holding grooves 3a. Therefore, if the side portions 4a, 4b formed in parallel with each other are deformed so as to be insertable into the holding groove 3a, they cannot be inserted into the holding groove 3a. At the time of deformation, if the wires of the respective side portions 4a, 4b lose their uniformity, it will be difficult to insert into the holding groove 3a.
若線圈4中之各邊部4a、4b之線材失去整齊性,則難以提高卷線之分層因數,從而無法謀求發電機或馬達之高效率化或小型化等。 When the wire of each of the side portions 4a and 4b in the coil 4 loses the uniformity, it is difficult to increase the layering factor of the winding wire, and it is not possible to increase the efficiency or size of the generator or the motor.
又,如圖16所示,為了提高卷線之分層因數,亦有使形成1個卷線層之定子線圈12之各邊部13a、14a分別插通至複數個溝槽11b(圖中為2個溝槽11b)之情形。 Further, as shown in FIG. 16, in order to increase the layering factor of the winding, the side portions 13a, 14a of the stator coil 12 forming one winding layer are respectively inserted into the plurality of grooves 11b (in the figure The case of two grooves 11b).
即,可想到:於將定子線圈12中的兩側之邊部13a、14a分別收納至複數個溝槽11b中之情形時,可如上述實施形態般獲得定子線圈12,該定子線圈12由將兩側之邊部13a收納至隔開既定間隔之溝槽11b中之內線圈13、以及將邊部14a收納至於收納有內線圈13之溝槽11b之外側鄰接之溝槽11b內之外線圈14構成。 That is, it is conceivable that when the side portions 13a and 14a of both sides of the stator coil 12 are housed in the plurality of grooves 11b, the stator coil 12 can be obtained as in the above embodiment, and the stator coil 12 is The side portions 13a on both sides are accommodated in the inner coil 13 in the groove 11b spaced apart from each other, and the side portion 14a is accommodated in the groove 11b adjacent to the outer side of the groove 11b in which the inner coil 13 is accommodated. Composition.
然而,於比較例之定子之製造方法中,由於由內線圈13及外線圈14構成之定子線圈12之邊部13a、14a成為彼此平行,因此難以一 面確保內線圈13與外線圈14之各邊部13a、14a之平行,一面使兩側之各邊部13a、14a變形為可***至呈放射狀之各溝槽11b中。又,更難以一面確保其整齊性,一面將各邊部13a、14a***至溝槽11b中。 However, in the manufacturing method of the stator of the comparative example, since the side portions 13a and 14a of the stator coil 12 composed of the inner coil 13 and the outer coil 14 are parallel to each other, it is difficult to ensure the sides of the inner coil 13 and the outer coil 14 while ensuring The portions 13a and 14a are parallel to each other, and the side portions 13a and 14a on both sides are deformed so as to be insertable into the respective grooves 11b which are radially formed. Further, it is more difficult to ensure the uniformity while inserting the side portions 13a and 14a into the groove 11b.
相對於此,本實施形態中,如圖14所示,自狹縫32a、32b推出並***至對應之溝槽11b內的邊部13a、14a一面維持***至狹縫32a、32b內之線材8之狀態一面移動,從而直接***至溝槽11b內。因此,只要邊部13a、14a中之線材8得以整齊捲繞,便可以整齊捲繞之線材8之狀態***至對應之溝槽11b中。因而,可將由整齊之線材8構成之邊部13a、14a直接***至定子鐵心11(圖16及圖17)之溝槽11b中。 On the other hand, in the present embodiment, as shown in Fig. 14, the wires 8 inserted into the slits 32a, 32b are pushed out from the slits 32a, 32b and inserted into the side portions 13a, 14a in the corresponding grooves 11b. The state is moved while being inserted directly into the groove 11b. Therefore, as long as the wire 8 in the side portions 13a, 14a is wound neatly, it can be inserted into the corresponding groove 11b in a state in which the wire 8 is wound neatly. Therefore, the side portions 13a, 14a composed of the aligned wires 8 can be directly inserted into the grooves 11b of the stator core 11 (Figs. 16 and 17).
於捲線機20中,可獲得由內線圈13與外線圈14構成之定子線圈12,因此只要其等經整齊捲繞,便可以此狀態直接交接線圈12。因而,可將整齊狀態之邊部13a、14a直接***至定子鐵心11之溝槽11b內。 In the winding machine 20, the stator coil 12 composed of the inner coil 13 and the outer coil 14 can be obtained. Therefore, the coil 12 can be directly delivered in this state as long as it is wound up neatly. Therefore, the side portions 13a, 14a in the neat state can be directly inserted into the grooves 11b of the stator core 11.
因此,可提高溝槽11b中之線材8之分層因數,從而可謀求使用該定子10之發電機或馬達之高效率化或小型化等。 Therefore, the layering factor of the wire 8 in the groove 11b can be increased, and the efficiency or miniaturization of the generator or the motor using the stator 10 can be achieved.
又,如圖15所示,內線圈13與外線圈14之邊部13a、14a之間隔D1、D2不同。因而,即使將邊部13a、14a***至各別的溝槽11b中,內線圈13之線圈尾端部13b亦不會超過外線圈14之線圈尾端部14b而自鐵心11之端面突出。因此,亦可避免如內線圈13之線圈尾端部13b與外線圈14之線圈尾端部14b重合而造成線圈尾端部13b、14b之成形變得困難之事態。 Moreover, as shown in FIG. 15, the gaps D1 and D2 of the inner coil 13 and the side portions 13a and 14a of the outer coil 14 are different. Therefore, even if the side portions 13a, 14a are inserted into the respective grooves 11b, the coil end portion 13b of the inner coil 13 does not protrude beyond the end portion 14b of the outer coil 14 and protrudes from the end surface of the core 11. Therefore, it is also possible to avoid a situation in which the formation of the coil end portions 13b, 14b becomes difficult if the coil tail end portion 13b of the inner coil 13 overlaps with the coil tail end portion 14b of the outer coil 14.
