Description

热压接装置
技术领域
本发明涉及通过加热对多个部件实施接合的热压接装置。
背景技术
已知有通过加热多个部件使这些部件熔融来将第一部件接合于第二部件的热压接装置。
在国际公开2017/47786号所记载的热压接装置中，使被压接部件的凸起从形成在圆锥状部件的内周面上的孔突出，通过使用圆锥状的电极片使该凸起熔融，从而将圆锥状部件与被压接部件接合。
在国际公开2017/47786号所记载的热压接装置中，在电流流过电极片时产生电流的偏差，电极片的温度变得不均匀。如果电极片的温度变得不均匀，热压接对象的树脂的熔融出现不充分的部位，存在接合强度变低的可能性。
发明内容
本发明是鉴于所述情况而作出的，其目的在于提供一种能够可靠地进行热压接的热压接装置。
解决课题的手段
本发明的热压接装置使第二部件的凸起熔融来接合第一部件和第二部件，所述第一部件为筒状且宽度从下面向上面扩大，所述第二部件的凸起从所述第一部件上形成的贯通孔穿通并自所述第一部件的内周面向内侧方向突出，该热压接装置的特征在于，具备：加热片，其具有外周面以沿着所述第一部件的内周面的方式形成的主体部，和连接于所述主体部的内周面且沿着所述主体部的径向延伸的2个板状的端子部；和，电力供给部，其配置在所述加热片的上方，介由所述端子部向所述主体部供电，所述主体部和所述端子部的至少一方在规定的方向上以不均匀的厚度形成。需要说明的是，优选所述主体部和所述端子部中的至少一方，在规定的方向上以不均匀的厚度形成，以使得与形成为均匀的厚度的情况相比，因所述电力供给部供给的电而产生发热的所述主体部的各部分的发热量的偏差变小。
将电流设定为I、电阻设定为R时，发热量可以通过I2×R求出，将电阻率设定为ρ、长度设定为L、截面积设定为S时，电阻可以通过R＝ρ×L/S求出。即，发热量与电阻R成正比，电阻R与截面积S成反比，发热量也与截面积S成反比。因此，若截面积变小，则发热量变大。
根据本发明，主体部及端子部的至少一方在规定的方向上以不均匀的厚度形成。例如，通过使主体部和端子部的至少一方在规定的方向上的厚度不均匀，以使得电流小的部分的厚度比电流大的部分的厚度小，与以均匀的厚度形成的情况相比，因电力供给部供给的电而产生发热的主体部的各部分的发热量的偏差变小。由此，与主体部及端子部的至少一方以均匀的厚度形成的情况相比，能够抑制由加热片引起的熔融不均，从而能够可靠地进行热压接。
另外，优选的是，所述主体部的下端部、也即窄幅侧的所述主体部与所述端子部的连接部分的厚度比所述主体部的上端部、也即宽幅侧的所述主体部与所述端子部的连接部分的厚度厚。
从电力供给部流入端子部的电容易向下方流动，但不容易向侧方流动。因此，在主体部与端子部的连接部分，上部的电流比下部的电流小。
根据上述结构，主体部与端子部的连接部分形成上部为截面积小的薄壁且下部为截面积大的厚壁。这些截面积通过下述方式被设定：与连接部分的上部和下部为相同形状(截面积)的现有技术相比，电流小的上部(截面积：小)的发热量(I2×R)与电流大的下部(截面积：大)的发热量之差变小。由此，能够使连接部分传递至主体部的热量差比以现有技术中的热量差小，从而能够抑制主体部的上部和下部的熔融不均，进而能够可靠地进行热压接。
进一步地，优选所述主体部与所述端子部的连接部分侧的厚度比所述主体部与所述端子部的连接部分侧以外的厚度厚。
由于流过主体部的电在主体部的周向流动，所以在主体部中，与端子部的连接部分的电流大，离端子部最远的部分的电流变小。
根据上述结构，主体部的与端子部的连接部分的厚度形成得比其他部分厚。这些厚度通过下述方式被设定：主体部的与端子部的连接部分和主体部的其他部分的厚度相同的现有技术相比，电流大的连接部分(截面积：大)的发热量与离开端子部的、电流小的其他部分(截面积：小)的发热量的差变小。由此，与以往的情况相比，能够抑制主体部的周向的熔融不均，从而能够可靠地进行热压接。
另外，优选所述端子部的与所述主体部的宽幅侧连接的外侧部分的厚度比所述端子部的与所述主体部的窄幅侧连接的内侧部分的厚度薄。
从电力供给部流入端子部的电容易向下方流动，但不容易向侧方流动。因此，在端子部中，在外侧部分处流动的电比在内侧部分处流向下部的电小。
根据上述结构，端子部形成为外侧部分比内侧部分薄。这些厚度通过下述方式被设定：与端子部的外侧部分和内侧部分为相同厚度(截面积)的现有技术中的端子部相比，与主体部的上部连接且电流小的端子部的外侧部分(截面积：小)的发热量、和与主体部的下部连接且电流大的端子部的内侧部分(截面积：大)的发热量的差较小。由此，能够使从端子部传递至主体部的热量差比以往的情况小，从而能够抑制主体部的上部和下部的熔融不均，进而能够可靠地进行热压接。

根据本发明，能够可靠地进行热压接。

具体实施方式
下面，参照附图说明本发明的实施方式。
如图1所示，热压接装置2具备加热片3、加热片驱动部4和保持台5。热压接装置2通过加热来压接具体后述的作为被压接材料的叶轮(impeller)30。
加热片3具备加热部6(主体部)和电极部7(端子部)。加热部6形成为大致圆锥台形状上下颠倒的形状，且沿叶轮30的内周面形成。加热部6的上端部及下端部为开口。需要说明的是，加热部6的形状不限于圆锥台形状，只要是筒状且宽度从下面向上面扩大的方式倾斜的形状即可，例如也可以是半球形状。
在加热片驱动部4上设置有具有正极和负极、且对电极部7供电的电力供给部9。
保持台5具备基台11和位于基台11上部的圆筒部12。在圆筒部12中收纳有叶轮30。在基台11的上表面，形成有在圆筒部12的内部向上方突出且插入到后述叶轮30的安装孔31c中的定位凸起11a。
如图2所示，电极部7具备与加热部6连接的第一电极部7a和第二电极部7b。第一电极部7a及第二电极部7b的与加热部6的上部连接的外侧部比该第一电极部7a及第二电极部7b的与加热部6的下部连接的内侧部壁薄。第一电极部7a及第二电极部7b以图2中左右对称的方式设置。需要说明的是，本发明的规定的方向是指加热部6的径向。
在第一电极部7a及第二电极部7b的内侧部分的切口中，插入在加热放置于保持台5的叶轮30时的保持台5的定位凸起11a。
如图1及图2所示，第一电极部7a的上端部固定在加热片驱动部4的电力供给部9的正极上并被电连接。第二电极部7b的上端部固定在电力供给部9的负极上并被电连接。根据该结构，从加热片驱动部4的电力供给部9的正极介由第一电极部7a向加热部6供电。流过加热部6的电介由第二电极部7b流向电力供给部的负极。需要说明的是，在形成于第一电极部7a及第二电极部7b的孔中，被插入固定螺钉(未图示)，该固定螺钉固定在电力供给部9上。
由于加热部6具有电阻，所以通过向加热部6供电，加热部6的整体发热。另外，加热片驱动部4构成为能够使电力供给部9沿上下方向移动，加热片驱动部4通过在上下方向上驱动供电部9，能够使加热片3沿图1的上下方向移动。
第一电极部7a的根部沿加热部6的内周面的斜面连接设置，顶端部从加热部6的上表面突出。加热部6的内周斜面与第一电极部7a通过R形状的第一连接部21连接。第一连接部21横跨加热部6的内周斜面和第一电极部7a而形成，构成加热部6的一部分。在第一电极部7a的厚度方向的两端形成有第一连接部21。
第二电极部7b的根部沿加热部6的内周面的斜面连接设置，顶端部从加热部6的上表面突出。加热部6的内周斜面和第二电极部7b通过R形状的第二连接部22连接。第二连接部22横跨加热部6的内周斜面和第二电极部7b而形成，构成加热部6的一部分。在第二电极部7b的厚度方向的两端形成有第二连接部22。
第二连接部22形成为从上端向下端(规定的方向)R形变大。由此，第二连接部22的上部壁薄(参照图3A)，下部壁厚(参照图3B)。
同样地，第一连接部21形成为从上端向下端(规定的方向)R形变大。由此，第一连接部21的上部壁薄(参照图3A)，下部壁厚(参照图3B)。需要说明的是，第一连接部21及第二连接部22不限于R形状，只要是上部薄下部厚的形状即可，也可以形成为直线的锥状。
在加热部6的外周面的上端部形成有凸状的高差部6a。高差部6a从加热部6的外周面的上端部向加热部6的半径方向外方突出，并且在加热部6的外周面的上端部的周向上以连续延伸成一周的方式形成。如后详述，高差部6a能够防止通过热压接而熔化的凸起32c所构成的熔融部32c1从加热片3的上端部的上方流出。
加热部6通过下述方式形成：与第一电极部7a及第二电极部7b连接的第一连接部21及第二连接部22的厚度最厚，距离第一连接部21及第二连接部22最远的中间部6b的厚度最薄。另外，在加热部6上形成有底板部6c。需要说明的是，本发明的规定的方向为加热部6的周向。
如图4所示，叶轮30是在风扇等中用于送风的部件。叶轮30具有分别由聚丙烯(PP)构成的树脂制的主体部31(第一部件)和叶片部32(第二部件)。
如图4～8所示，主体部31由在内部形成有中空部31a的锥台筒状形成。主体部31的图6中的下端部受下板部31b封堵。在下板部31b上形成有安装孔31c，驱动叶轮30时的驱动源的驱动轴插入该安装孔31c而被安装。安装孔31c以对置的部分的2个部位的圆弧成为被D切割的形状而形成。需要说明的是，主体部31的形状并不限于錐台形状，只要是以筒状的形式宽度从下表面向上表面扩大的方式倾斜的形状即可，例如也可以是半球形状。
在主体部31的侧面形成有多个接合孔31d。接合孔31d从主体部31的侧面的径向中央近旁向主体部31的侧面的外周侧沿主体部31的侧面周向斜向延伸。接合孔31d延伸到主体部31的侧面的外周部近旁。
接合孔31d的内周部由贯通孔构成。接合孔31d的外周部由从主体部31的侧面凹陷的槽构成。接合孔31d在主体部31的侧面的周向上等间隔地形成有多个(在本实施方式中为14个)。
如图7～9所示，在主体部31的下板部31b的内表面形成有向上方延伸的圆柱状的中央凸部31e。中央凸部31e以与圆盘形状的下板部31b同轴的方式形成。安装孔31c贯通中央凸部31e及下板部31b。
当将叶轮30收纳在保持台5的圆筒部12中时，保持台5的定位凸起11a插入于安装孔31c中。叶轮30因定位凸起11a插入于安装孔31c中而被定位。
在相当于后述的凸起32c通过热压接熔融而构成的熔融部32c1(参照图10)的下端部的位置上形成有隔壁31f、也即在进行热压接前的状态的主体部31的内周面。隔壁31f以圆筒状且与中央凸部31e同轴的方式形成。隔壁31f以直径比中央凸部31e的直径大的方式包围中央凸部31e的方式而形成。
隔壁31f具有下述程度的高度：进行热压接而将加热片3抵接于凸起32c时，隔壁31f不会与加热片3抵接，且熔融部32c1不会从隔壁31f与主体部31的内周面之间溢出。隔壁31f阻止通过热压接而熔融的凸起32c所构成的熔融部32c1朝向比隔壁31f更低的图9中的下方流动。
如图7及图9所示，在主体部31的内周面上形成有内周扩径部31g。内周扩径部31g是主体部31的侧面形成得较薄的部分。内周扩径部31g在从主体部31的与隔壁31f连接的部分的近旁到图9中的主体部31的上端部之间形成。
在实施热压接时，在内周扩径部31g的内周面与后述的加热片3的外周面之间确保规定的间隙。在该规定的间隙中，能够保持规定量的由熔融的凸起32c构成的熔融部32c1。
另外，在进行熱接前的状态的主体部31的内周面上且在接合孔31d的近旁，形成有调整凸部31h。相对于每一接合孔31d各形成有一个调整凸部31h，该调整凸部31h向叶片部32提供该叶片部32接合于主体部31所需的量的树脂。调整凸部31h通过热压接熔融，与熔融后的凸起32c成为一体地构成熔融部32c1。
如图4所示，叶片部32形成为板状,具备根部侧的骨部32a、顶端侧的叶片主体部32b和凸起32c。叶片部32对应于接合孔31d而形成有14个。骨部32a形成为与接合孔31d大致一致的形状，与接合孔31d嵌合。
骨部32a的根部与主体部31一体地形成。如图4所示，叶片部32在骨部32a未嵌合于接合孔31d的状态下，叶片部32以骨部32a的根部为中心转动(折弯)。由此，如图5所示，骨部32a嵌合于接合孔31d。
叶片主体部32b形成为与骨部32a连接设置且弯曲的形状。如图5所示，在从主体部31的轴向观察时，14个叶片主体部32b以相邻的部件彼此重叠的方式形成。
凸起32c形成为大致三角形状，并且连接设置在骨部32a上。凸起32c在骨部32a嵌合于接合孔31d时，嵌入接合孔31d，并从主体部31的内周面向中空部31a突出(参照图9)。
(热压接)
图9是表示在本发明的实施方式的热压接中加热片3开始熔融凸起32c的情况的剖面图。图10是表示在本发明的实施方式的热压接中加热片3将凸起32c及隔壁31f熔融后的状态的剖面图。
在热压接中，首先，将叶轮30收纳在保持台5的圆筒部12中，在叶轮30的安装孔31c中插入保持台5的定位凸起11a。由此，如图1所示，叶轮30形成被保持在保持台5上的状态。
接着，加热片驱动部4使加热片3下降，向主体部31的中空部31a插入加热片3。
然后，如图9所示，通过使加热片3的加热部6与14个凸起32c抵接，使调整凸部31h熔融的同时，使14个凸起32c熔融而成为熔融部32c1。
熔融部32c1向下方流动。但是，加热片3的加热部6不与隔壁31f抵接，隔壁31f未发生熔融。因此，向下方流动的熔融部32c1被隔壁31f阻止向比隔壁31f靠下方的位置流动，从而堆积在隔壁31f与主体部31的内周面之间。由此，熔融部32c1的树脂量被维持在规定的量上。
然后，加热片驱动部4进一步使加热片3下降，使其与隔壁31f抵接，然后停止加热片3的下降。由此，隔壁31f被熔融。隔壁31f一边向主体部31的外周方向变形一边发生熔融。熔融后的隔壁31f与熔融部32c1成为一体，熔融部32c1的树脂量进一步增加。
在隔壁31f充分熔融后，加热片驱动部4使加热片3下降，按压熔融部32c1。而且，在加热部6的下端成为与中央凸部31e的内表面相同的高度的情况下，加热片驱动部4停止加热片3的下降。
通过所述动作，隔壁31f与熔融部32c1形成一体化，熔融部32c1主要配置于内周扩径部31g上。然后，通过降低加热片3的温度，使熔融部32c1固化。构成熔融部32c1的14个叶片部32的凸起32c发生熔融而被一体化后成为固化连结的状态，且与主体部31接合。如上所述被热压接的叶轮30构成所谓的斜流风扇。
(电流)
如图11所示，由加热片驱动部4的电力供给部9供给的电从电力供给部9的正极流向第一电极部7a的上部。流过第一电极部7a的上部的电向第一电极部7a的下部及侧方流动。流过第一电极部7a的下部及侧方的电通过第一连接部21流向加热部6。
流过加热部6的电自加热部6的上部流向下部。另外，流过加热部6的电沿着加热部6的周向流动。流过加热部6的周向的电通过中间部6b流到第二连接部22。
从加热部6及第一连接部21的下方流过的电通过底板部6c流向第二连接部22。流过第二连接部22的电，向第二电极部7b流动。
流过第二电极部7b的电自第二电极部7b的下部向上部流动。流过第二电极部7b的上部的电向电力供给部9的负极流动。以上是关于热压接装置2中的电流的描述。
自电力供给部9的正极流过第一电极部7a上部的电容易流向下方(也包括斜下方)，但不容易向侧方流动。因此，在连接加热部6和第一电极部7a的第一连接部21中，上部的电流变得比下部的电流小。在将电流设为I、电阻设为R时，发热量以I2×R求出，因此上部的发热量变得比下部的发热量小。
在将电阻率设定为ρ、将长度设定为L、将截面积设定为S时，电阻R可以通过R＝ρ×L/S来求出。即，发热量与电阻R成正比，电阻R与截面积S成反比，发热量也与截面积S成反比。因此，当截面积变小时，发热量变大。
在本实施方式中，第一连接部21形成为上部是截面积较小的壁薄部分(参照图3A)，下部是截面积大的壁厚部分(参照图3B)。这些截面积通过下述方式被设定：与第一连接部21的上部和下部为相同形状(截面积)的现有技术相比，电流小的上部的发热量(I2×R)与电流大的下部的发热量的差变小。由此，能够使由第一连接部21的上部及下部传递至加热部6的热量差比现有技术中的热量差小，从而能够抑制加热部6的上部和下部的熔融不均，进而可靠地进行热压接。
另外，在第二连接部22的下部，有通过底板部6c的电和沿加热部6的周向流过的电流动。另一方面，在第二连接部22的上部仅有沿周向流过加热部6的电流动。因此，第二连接部22的下部的电流比第二电极部7b的上部的电流大。
在本实施方式中，第二连接部22形成为上部是截面积小的壁薄部分(参照图3A)，下部是截面积大的壁厚部分(参照图3B)。这些截面积通过下述方式被设定：与第二连接部22的上部和下部为相同截面积的现有技术相比，电流小的上部的发热量(I2×R)与电流大的下部的发热量的差变小。由此，能够使由第二连接部22的上部及下部传递至加热部6的热量差比现有技术中的热量差小，从而能够抑制加热部6的上部和下部的熔融不均，进而可靠地进行热压接。
另外，从电力供给部9的正极流过第一电极部7a的上部的电容易向下方流动，但不容易流向侧方。因此，第一电极部7a的内侧部分的电流比第一电极部7a的外侧部分的电流大。
在本实施方式中，第一电极部7a以外侧部分的厚度比内侧部分的厚度薄的方式形成。这些厚度通过下述方式被设定：与第一电极部7a的外侧部分和内侧部分为相同厚度的现有技术相比，电流小的外侧部分即上部的发热量(I2×R)与电流大的内侧部分即下部的发热量的差变小。由此，能够使第一电极部7a传递至加热部6的热量差比以现有技术中的热量差小，从而能够抑制加热部6的上部和下部的熔融不均，进而可靠地进行热压接。
另外，在第二电极部7b的下部的内侧部分，流过通过底板部6c、第二连接部22的电以及沿周向流过加热部6并通过第二连接部22的电。另一方面，在第二电极部7b的上部的外侧部分，仅流过沿加热部6的周向流过并通过第二连接部22的电。因此，第二电极部7b的内侧部分的电流比第二电极部7b的外侧部分的电流大。
在本实施方式中，第二电极部7b形成为外侧部分的厚度比内侧部分的厚度薄。这些厚度通过下述方式被设定：与第二电极部7b的外侧部分和内侧部分为相同厚度的以往的加热片相比，电流小的外侧部分即上部的发热量(I2×R)与电流大的内侧部分即下部的发热量之差变小。由此，能够使第二电极部7b传递至加热部6的热量差比以往的加热片中产生的热量差小，从而能够抑制加热部6的上部和下部的熔融不均，进而能够可靠地进行热压接。
另外，在加热部6中，电流自第一连接部21沿周向流动，通过中间部6b流向第二连接部22。因此，中间部6b的电流比第一连接部21的电流小。另外，在第二连接部22中流通有沿加热部6的周向流动且通过中间部6b的电和通过底板部6c的电。因此，中间部6b的电流比第二连接部22的电流小。
在本实施方式中，加热部6以中间部6b的厚度比第一连接部21以及第二连接部22的厚度薄的方式形成。这些厚度通过下述方式被设定：与第一连接部21及第二连接部22与中间部6b的厚度相同的现有技术中的加热片相比，电流大的第一连接部21及第二连接部22的发热量(I2×R)与电流小的中间部6b的发热量之差变小。由此，与以往的加热片相比，能够抑制第一连接部21及第二连接部22与中间部6b的熔融不均，从而能够可靠地进行热压接。
在所述实施方式中，第一连接部21及第二连接部22以厚度从上端向下端变厚(第一形成条件)的方式形成。另外，加热部6以中间部6b的厚度比第一连接部21以及第二连接部22的厚度薄(第二形成条件)的方式形成。而且，第一电极部7a及第二电极部7b以外侧部分比内侧部分薄(第三形成条件)的方式形成。本发明不限于此，只要进行第一形成条件～第三形成条件中的至少1个形成条件即可。
在所述实施方式中，对第一连接部21及第二连接部22的上部及下部的截面积的不同进行了说明，但不仅限于上部与下部不同，与第一连接部21及第二连接部22以均匀的厚度形成的现有技术中的加热片相比，第一连接部21及第二连接部22的整体以不均匀的厚度形成，使得加热部6的各部分的发热量的偏差变小。由此，与以往的加热片相比，能够抑制加热部6的各部分的熔融不均，能够可靠地进行熱压接。
在所述实施方式中，对加热部6的第一连接部21及第二连接部22的截面积与中间部6b的截面积的不同进行了说明，但不限于第一连接部21及第二连接部22与中间部6b不同，与加热部6以均匀厚度形成的现有技术相比，加热部6的整体在周向上以不均匀的厚度形成，以使得加热部6的各部分的发热量的偏差变小。由此，与以往的加热片相比，能够抑制加热部6的各部分的熔融不均，从而能够可靠地进行热压接。
