请参见图1所示,本申请的一实施例中提供的卷绕机,包括转塔200、隔膜切刀装置100、贴胶装置及下料装置。隔膜切刀装置100、贴胶装置及下料装置围绕该转塔200布设。具体地,隔膜切刀装置100、下料装置及贴胶装置沿着逆时针方向围绕该转塔200布设。
转塔200上设有基座201和至少一个可绕自身轴线可转动的(即可自转的)卷针202。转塔200转动,带动卷针202实现公转以变换工位,卷针202自转实现电芯的卷绕和收尾。具体的,隔膜作为基材,与极片一起,在转塔200处于卷绕工位的卷针202上逐渐卷绕成电芯。电芯卷绕形成后,转塔200公转,电芯随卷针202转移到收尾工位。此时,隔膜未被裁断,其与转塔200的卷针202上卷绕的电芯连接在一起。电芯收尾时,隔膜切刀装置100将隔膜裁断,而分为卷料端的隔膜和断料端的隔膜,处于收尾工位的卷针202自转,将断料端的隔膜收卷到电芯上。贴胶装置用于将胶带贴附于电芯的收尾端,避免电芯松散。需要说明的是,电芯的收尾端可以是断料端的隔膜(即电芯采用隔膜收尾的方式时),也可以是极片(即电芯采用极片收尾的方式时)。下料装置用于对卷绕于卷针202上的电芯进行下料。
上述卷绕机,通过转塔上的卷针卷绕形成电芯,然后分别通过隔膜切刀装置切断隔膜,卷针202继续对断料端的隔膜进行卷绕,贴胶装置将胶带贴附于电芯的收尾端,以完成电芯的收尾工序。最后利用下料装置对电芯进行下料。如此,电芯的卷绕、收尾、贴胶及下料等工序配合紧密,自动化程度高,有利于提高生产效率及降低成本。
具体地,请参见图1及图2所示,基座201的一侧设有卷针尾座203。卷针202卷绕电芯时,卷针202会插入卷针尾座203中,并带动卷针尾座203一起自转以保护卷针202,提高卷针202的刚性,使得卷针202自转更稳定。

请参见图5、图6及图7所示,隔膜切刀装置100包括切刀组件1、用以驱动切刀组件1整体向隔膜来回运动的第一驱动组件2以及与切刀组件1相连的调节组件3。切刀组件1包括切刀安装架11、安装在切刀安装架11上的切刀12、用以驱动切刀12以切断隔膜的切刀驱动件13以及安装在切刀安装架11上的隔热块14。在本申请的一种实施方式中, 切刀12采用热切刀,在裁切隔膜时,切刀12被加热,加热至高温的切刀12靠近隔膜最终热熔切断隔膜实现裁切。此处需要说明的是,切刀12也可以采用电热丝等其它裁切机构,能够实现裁断隔膜即可。在另一实施例中,切刀12包括第一切刀121以及第二切刀122,其中第一切刀121为热切刀,第二切刀122为电热丝。进一步地,第一切刀121夹在隔热块14之间,第一切刀121的刀刃端部较扁,使得刀刃位置处的隔热块14与第一切刀121之间具有间隙,第二切刀122的电热丝设置在该间隙中。当切刀组件1的切刀12采用热切刀时,工艺为隔膜收尾,即电芯收尾时,由隔膜最后包裹整个电芯,并利用胶带粘贴隔膜的尾端以防止电芯松散;当切刀组件1的切刀12采用电热丝时,工艺为极片收尾,即电芯收尾时,由极片(一般为阴极极片)最后包裹整个电芯,并利用胶带粘贴极片的尾端以防止电芯松散。由此,根据工艺的需求,能够自由选择对应的切刀。由于第一切刀121以及第二切刀122均需要加热至高温才能实现对隔膜的熔断裁切,在采用一种切刀时,另一种切刀并不会影响当前的裁切。
具体到实施方式中,切刀安装架11设有U形开口111、位于U形开口111的上端的上壁部112以及位于U形开口111的下端的下壁部113,切刀12安装在U形开口111内。
具体到实施方式中,切刀驱动件13为气缸,其安装在切刀安装架11上。切刀驱动件13的输出端与切刀12相连,用于驱动切刀12靠近并切断隔膜。另外,切刀安装架11上还设置有朝向转塔200方向设置的导杆132和直线轴承131,导杆132可穿过直线轴承131朝向转塔200运动。导杆132的一端连接切刀12,切刀驱动件13驱动切刀12运动时,导杆132能够提供导向,引导切刀12准确地裁断隔膜。
隔热块14包括设置在上壁部112的上隔热块141以及设置在下壁部113的下隔热块142,切刀12设置在上隔热块141和下隔热块142之间。下隔热块142靠近隔膜的端部设有用以吸附隔膜的吸附装置(未图示)。具体地,吸附装置开有气孔,气孔相通并与外部的抽气装置连通;通过抽气装置对吸附装置内部抽真空,形成负压。当切刀组件1切断隔膜时,吸附装置能够吸住断料一端,防止切断后断料掉落,影响电芯的收尾。另外,切刀组件1还包括安装在切刀驱动件13与所述切刀12之间的后隔热块15,以隔绝热量使之不影响切刀驱动件13的使用寿命。具体地,后隔热块15也安装在U形开口111内。通过设置隔热块14和后隔热块15,一方面,可以隔绝切刀12采用热切刀时产生的热量,防止其影响其它相近的机械部件;另一方面,能够起到保护作用,防止误伤操作人员。
第一驱动组件2驱动切刀组件1和调节组件3靠近或者远离转塔200;切刀驱动件13驱动切刀组件1靠近隔膜,实现隔膜裁切;调节组件3用于调节切刀组件1的高度。在本申请图6所示的实施方式中,调节方向为上下方向B-B。
具体地,第一驱动组件2包括电机21、通过同步带组件20与电机21相连的丝杆22、与丝杆22相配合的丝杆螺母23、连接丝杆螺母23的丝杆连接块24(见图7)以及导轨25,其中导轨25朝向转塔200设置。
调节组件3包括与第一驱动组件2相连的第一安装板31以及调节螺钉32。请参图6所示,第一安装板31通过丝杆螺母23与第一驱动组件2相连;同时,第一安装板31通过滑块310与导轨25滑动连接。具体地,第一安装板31连接丝杆连接块24,通过丝杆连接块24、丝杆螺母23与丝杆22相连,电机21驱动丝杆22带动第一安装板31沿导轨25运动。当电芯卷绕完毕,转塔200公转,带动卷绕形成的电芯拖着未被裁断的隔膜转移到收尾工位,此时,隔膜被拉开,使得切刀组件1正对隔膜。第一驱动组件2驱动切刀组件1靠近转塔200,随后,切刀驱动件13驱动切刀12去切隔膜;切完后,切刀组件1又能由第一驱动组件2驱动远离转塔200,进行避位,以方便转塔200公转,带动卷针换位。
第一安装板31在与丝杆螺母23相连的位置设有缺口312(见图7)以及位于缺口312内且用以固定丝杆连接块24的卡板313(见图7)。缺口312在调节方向具有可供卡板313和丝杆连接块24活动的间隙,使得丝杆22在带动丝杆螺母23、丝杆连接块24、卡板313和第一安装板31沿其轴向运动时,在上下方向B-B上有活动余量。通过这种有活动余量的浮动连接方式,消减电机21运动时,丝杆22与导轨25之间的相对不稳定性(例如导轨25固定,而丝杆22晃动,导致丝杆22与导轨25的相对位置发生变化。),以增加整个第一驱动组件2运行的稳定性。
在本申请图6所示的实施方式中,第一安装板31设有沿调节方向分布的若干螺纹孔311,切刀安装架11设有与相应的螺纹孔311相配合的腰形孔114。可以理解,根据调节位置的不同,暴露在腰形孔114中的螺纹孔311可能是不同的。腰形孔114与螺纹孔311通过螺丝固定以调整所述切刀安装架11的安装位置。腰型孔114在调节方向有一定的调整量,通过腰型孔114与螺纹孔311的配合能够实现粗调整,以满足切刀12上下调整的需要。
具体到实施例中,调节组件3还包括安装在第一安装板31上的调节安装座33。调节安装座33与对应的螺纹孔311相固定。可以理解,根据调节位置的不同,调节安装座33不存在固定不变的安装位置;相反,通过不同位置的螺纹孔311,调节安装座33可以安装在不同的位置。具体地,调节安装座33上也开设有与螺纹孔311相配合的螺纹孔,通过螺丝能够固定调节安装座33与第一安装板31的相对位置。同时,在调节安装座33上设置有调节螺钉32,且二者相对固定,调节螺钉32在调节安装座33内可转动,但不会在上下方向B-B上升降。调节螺钉32与切刀安装架11螺纹连接,具体地,切刀安装架11设有与调节螺钉32相配合的调节螺钉孔115,调节螺钉孔115沿调节方向设置,调节螺钉32 则沿调节方向插入调节螺钉孔115中与之螺纹配合。具体地,调节螺钉孔115可以设置在切刀安装架11的顶部,调节螺钉32设置在切刀安装架11的上方并插入调节螺钉孔115中与之配合;调节螺钉孔115也可以设置在切刀安装架11的底部,调节螺钉32设置在切刀安装架11的下方并插入调节螺钉孔115中与之配合。由此,转动调节螺钉32,切刀安装架11就可以沿着螺纹升降。在前述粗调整的基础上,通过调节螺钉32,能够实现精调整。
优选地,第一安装板31设有凹部314(见图5),螺纹孔311设置在凹部314内。切刀安装架11和调节安装座33至少部分安装在凹部314内且均与第一安装板31上相对于凹部314突出的侧壁相抵压,以增加整体结构的刚性,确保安装稳定性的同时,确认安装是否准确。
调整时,在一种实施方式中,人工手动把第一安装板31调到所需的位置,此时腰型孔114中暴露有螺纹孔311;在完全锁紧腰型孔114和螺纹孔311之前,调整调节安装座33及调节螺钉32至调节螺钉32能与第一安装板31相连的位置,使得调节螺钉32栓入调节螺钉孔115中;然后,固定调节安装座33的位置,调节螺钉32的位置高度保持不变,旋转调节螺钉32,第一安装板31能够顺着调节螺钉孔115中的螺纹上下微调一定距离至所需的准确位置,从而提高了隔膜切刀装置100的适应性。
请参图1及图2所示,卷绕机还包括设置在基座201上的靠板组件600,靠板组件600与卷针202配套设置,即靠板组件600的套数与卷针202的数量相同,且一一对应设置。
靠板组件600包括第二安装板61以及靠板62,其中第二安装板61设置在基座201上。第二安装板61上沿上下方向B-B开设有若干螺纹孔611;靠板62开设有腰型孔621;腰型孔621与螺纹孔611通过螺钉配合安装。腰型孔621在上下方向B-B上具有一定的调整空间,便于调整靠板62与基座201的相对位置。根据工艺的不同,隔膜的切割位置也不同,由此,切刀12的位置需要调节,靠板62的位置也需要对应地调整。
靠板62上还开设有与切刀12相对的缺口622,以在切刀12裁断隔膜时有效避位。另外,靠板62的上部开有气孔623,靠板62的下部还开有吸孔(未图示)。气孔623相通并与外部的抽气装置连接,吸孔也与外部的抽气装置连接,抽气装置能对靠板62内抽真空,从而利用负压吸住隔膜。优选地,切刀12裁切隔膜前,气孔623和吸孔吸住隔膜,可以辅助张紧隔膜;实际裁切隔膜时,以缺口622所在的位置为分界线将靠板62分为上部和下部,其中,在设置隔热块14的实施方式中,第一驱动组件2驱动切刀安装架11抵靠靠板62,使气孔623所在的靠板62的上部与上隔热块141抵接,吸孔所在的靠板62的下部 与下隔热块142抵接,以张紧位于所述上隔热块141与下隔热块142之间的隔膜,便于裁断隔膜;在不设置隔热块14的实施方式中,第一驱动组件2驱动切刀安装架11抵靠靠板62,使气孔623所在的靠板62的上部与上壁部112抵接,吸孔所在的靠板62的下部与下壁部113抵接,以张紧位于上壁部112与下壁部113之间的隔膜,便于裁断隔膜。隔膜裁断后,切刀组件1收回,料卷端的隔膜仍被气孔623吸住,能够避免隔膜脱力后因为静电打折产生褶皱,便于新电芯的卷绕;断料端的隔膜在裁断后被吸孔吸住,防止其掉落,便于收尾时隔膜平稳入卷、不容易打折;断料端的隔膜用以包裹电芯成型。第二安装板61的下端设有能够转动的靠辊63。在一种实施方式中,靠辊63包括辊轴631和辊筒632,其中辊轴631安装在第二安装板61上,辊筒632转动安装在辊轴631上。
请参见图3及图4所示,具体到实施例中,卷针202包括至少两个,靠板组件600与卷针202一一对应设置。当卷绕形成有电芯的卷针202随着转塔的转动从卷绕工位转动至收尾工位时,其中另一个卷针202转动至卷绕工位,且隔膜被电芯牵引而抵靠于与位于收尾工位的卷针202相对应的靠板组件600的靠板62上,以使隔膜对准位于卷绕工位的卷针202的插缝,以便于位于卷绕工位的卷针202沿其轴向移动而使得隔膜插入该卷针202的插缝中,为隔膜被裁断后位于卷绕工位的卷针202进行再次的卷绕作业做好准备。也就是说,靠板62除了起到与隔膜切刀装置100相配合切断隔膜的作用外,还具有对隔膜进行定位以使隔膜对准位于卷绕工位的卷针202的插缝的作用,方便隔膜插入位于卷绕工位的卷针202的插缝。如此,与传统的卷绕机中需要额外设置定位装置,通过该定位装置的移动来带动隔膜与位于卷绕工位的卷针202的插缝对准的技术方案相比,本实施例中通过在转塔200上设置至少两个且一一对应的卷针202和靠板组件600,在设备结构方面,不需要额外设置可移动的定位装置,简化了卷绕机结构;同时,在工艺方面,不需要额外的对隔膜定位的工艺步骤,即在卷针202在卷绕工位和收尾工位之间切换时就实现了对隔膜的定位,有利于提高生产效率。
进一步地,在图3及图4所示的实施例中,转塔200上设置两个卷针202和两个靠板组件600,两个卷针202围绕基座201对称设置,且与两个靠板组件600一一对应。当卷绕有电芯的卷针202由卷绕工位(转塔200的左上区域)转动至收尾工位(转塔200的右下区域)时,另一卷针202由收尾工位转动至卷绕工位。此时,隔膜抵靠于与位于卷绕工位的卷针202相对应的靠板组件600的靠板62上,以使隔膜对准位于卷绕工位的卷针202的插缝。此时靠板62处于竖直状态,隔膜抵靠于该靠板62朝向隔膜切刀装置100一侧(即图4所示的靠板62的左侧)。可以理解的是,卷针202并不仅限于设置两个,在其他实施例中,也可设置两个以上,在此不作限定。
请参见图1及图8所示,卷绕机还包括用于辅助电芯收尾的收尾装置500,该收尾装置500包括第一压辊51、第二压辊52、第一压辊驱动装置53以及第二压辊驱动装置54。在本申请的一种实施方式中,第一压辊驱动装置53包括电机、丝杆与导轨,第二压辊驱动装置54包括气缸与导轨。通过在第一压辊驱动装置53中设置电机,能够提高收尾装置500的运动速度,从而提高效率。第一压辊驱动装置53动作时,电机驱动丝杆,丝杆带动与之相连的第二压辊52、第二压辊驱动装置54随着第一压辊51一起朝向转塔200上收尾工位的电芯运动。具体地,第一压辊驱动装置53驱动第一压辊51抵靠靠辊63以压紧两者间的隔膜,同时第二压辊52靠近隔膜,第二压辊驱动装置54再驱动第二压辊52抵靠处于收尾工位的卷针202上的电芯。当隔膜裁断收尾时,第一压辊51和靠辊63夹住断料端的隔膜,防止其掉落、产生形变,处于收尾工位的卷针202自转,第二压辊52压着电芯随转,便于压紧电芯防止其散架,并抚平收尾的基材使之更好地包裹电芯。
请参见图1、图8、图9及图10所示,卷绕机还包括设置在收尾装置500上的纠偏机构400,该纠偏机构400用以在阴极极片收尾时,对阴极极片进行检测和纠偏。具体地,第一压辊51设置在第一压辊安装板413上,纠偏机构400设置在该第一压辊安装板413的侧面,第一压辊驱动装置53驱动第一压辊安装板413带着第一压辊51运动时,纠偏机构400跟着一起靠近隔膜以及极片,方便之后对极片进行纠偏检测。
纠偏机构400包括纠偏驱动装置41和纠偏检测装置42,其中纠偏检测装置42包括纠偏传感器421,用于检测极片位置。若极片位置不准确,纠偏驱动装置41驱动第一压辊51,带动与第一压辊51抵紧的靠辊63以及被两者所夹紧的极片一起沿第一压辊51的轴向运动,使极片到达准确位置。此时,第一压辊51作为纠偏主动辊,靠辊63则作为纠偏从动辊。
具体地,纠偏驱动装置41包括纠偏驱动件411以及纠偏导向件412。在本申请的一种实施方式中,纠偏驱动件411包括电机、丝杆以及同步带组件。纠偏导向件412包括导轨。纠偏导向件412沿第一压辊51的轴向设置;第一压辊安装板413通过滑块与导轨滑动连接;纠偏驱动件411通过同步带组件,带动丝杆及与丝杆相连的第一压辊安装板413沿第一压辊51的轴向运动。第一压辊安装板413上设有朝向转塔200设置的导杆414;导杆414穿过第一压辊安装板413,且能够在第一压辊安装板413中沿自己的轴向运动。导杆414平行于第一压辊驱动装置53驱动第一压辊51运动的运动方向,导杆414的另一端连 接第一压辊51;导杆414上套有弹性件415(例如弹簧),弹性件415的两端分别抵接第一压辊安装板413和第一压辊51;由此,不管是隔膜收尾,还是阴极收尾,电芯拖着隔膜转至收尾工位,裁切隔膜前,第一压辊51抵靠靠辊63,此时,第一压辊51与靠辊63并非刚性接触,弹性件415通过自身的弹性变形能够为二者的抵靠提供活动余量,避免第一压辊51直接撞击靠辊63;同时,第一压辊51抵住靠辊63后,弹性件415被压缩,压缩产生的弹性势能驱使第一压辊51始终抵紧靠辊63,隔膜被裁断,处于收尾工位的卷针202自转收尾时,断料一端的隔膜、或者隔膜和极片从第一压辊51和靠辊63之间穿过被卷入电芯,第一压辊51与靠辊63随转,引导基材平稳地进入电芯,同时,由于弹性件415有一定的变形量、刚性小,第一压辊51与靠辊63之间的挤压力可变,不会扯住隔膜。
具体地,请参图10所示,纠偏检测装置42还包括调节螺杆422和调节气缸423,其中调节气缸423与调节螺杆422螺纹连接,调节螺杆422平行于第一压辊51的轴向设置,通过调节调节螺杆422可以变换调节气缸423的位置,以根据极片收尾时的入料位置进行调整,满足检测的需要。调节气缸423的输出端设有U型的传感器安装座424。在检测时,极片从传感器安装座424的U型口中穿过,U型口的两端设有两个纠偏传感器421,其中一个为信号发射单元,另一个为信号接收单元。极片收尾时,隔膜先被裁断,逐渐被卷入电芯中,而用于收尾的阴极极片仍被夹在第一压辊51与靠辊63之间,此时,第一压辊驱动装置53带着纠偏检测装置42靠近极片,调节气缸423驱动传感器安装座424带着纠偏传感器421沿第一压辊51的轴向插向极片,使极片穿入U型开口中。若极片位置准确,极片会完全遮住纠偏传感器421发出的信号;若极片位置不准确,根据极片对信号的遮盖量,系统能够计算出纠偏量,再反馈给纠偏驱动件411的电机,使之驱动第一压辊51沿其轴向运动所需量,使极片最终完全遮盖传感器的信号,完成纠偏。
在本申请图10所示的实施方式中,调节螺杆422的两侧设有两个与之平行的调节导杆425,调节螺杆422和调节导杆425上设有调节滑座426,调节滑座426上安装有所述调节气缸423。调节导杆425有导向和保护作用,保证纠偏传感器421的位置始终在平行于第一压辊51轴向的位置上调整,保证后期检测的精度。
本申请的收尾装置500能够辅助进行隔膜收尾或者极片收尾,其中:
当工作在隔膜收尾时:电芯在卷绕工位的卷针202上卷绕形成后,阴极极片和阳极极片先被裁断,绕进电芯中;转塔200公转变位,使卷绕有电芯的卷针202从卷绕工位变换 至收尾工位;
收尾装置500动作,第一压辊驱动装置53驱动第一压辊51抵靠靠辊63,压紧两者间的隔膜;第二压辊驱动装置54驱动第二压辊52抵靠收尾工位处卷针202上的电芯;
隔膜切刀机构100动作,第一驱动组件2驱动切刀组件1靠近转塔200;上隔热块141抵靠气孔623所在的靠板62的上部,下隔热块142抵靠靠板62的下部,压住两者间的隔膜,使得缺口622两端的隔膜被张紧;
切刀驱动件13驱动切刀12靠近隔膜,且利用第一切刀121(热切刀)裁断隔膜;
裁断的隔膜,其料卷一端被靠板62上部吸住,处于卷绕工位的卷针202夹住这段隔膜,开始新一轮的电芯卷绕,同时,处于收尾工位的卷针202自转,扯动断料一端的隔膜以收尾;
卷针202自转收尾,由于电芯被第二压辊52抵住,隔膜收尾时,第二压辊52能够时时抚平隔膜,保证收尾的稳定性。
当工作在极片收尾时:电芯在卷绕工位的卷针202上卷绕形成后,阳极极片先被裁断,绕进电芯中;阴极极片预留出最后包裹电芯一段后再被裁断;转塔200公转变位,使卷绕有电芯的卷针202从卷绕工位变换至收尾工位;
收尾装置500动作,第一压辊驱动装置53驱动第一压辊51抵靠靠辊63,压紧两者之间的隔膜和阴极极片;此处需要说明的是,由于隔膜和阴极极片在卷绕电芯时的入卷位置是隔膜在后,阴极极片在前,所以隔膜更靠近隔膜切刀机构100;而被裁断的阴极极片在掉落时,会向前方倾斜,能够自然地避免干涉到隔膜切刀机构100对隔膜的裁切;
第二压辊驱动装置54驱动第二压辊52抵靠卷针202上的电芯;
隔膜切刀机构100动作,第一驱动组件2驱动切刀组件1靠近转塔200;切刀驱动件13驱动切刀靠近隔膜,利用第二切刀122(即电热丝)的高热直接裁断隔膜,不需要张紧隔膜;
裁断的隔膜,其料卷一端被处于卷绕工位的卷针202夹住,开始新一轮的电芯卷绕,同时,处于收尾工位的卷针202自转,扯动断料一端的隔膜以收尾;
纠偏机构400动作,调节气缸423驱动传感器安装座424带着纠偏传感器421靠近极片,使极片穿入U型开口中,以检测极片位置;若需要纠偏,纠偏驱动件411驱动第一压辊51带着靠辊63一起夹着极片沿轴向运动,调整极片位置至完全遮盖纠偏传感器421的 信号;
卷针202自转收尾,由于电芯被第二压辊52抵住,隔膜收尾时,第二压辊52能够实时抚平隔膜,保证收尾的稳定性。
另外,为了便于靠辊63复位,可以设置复位气缸连接靠辊63的辊轴631的一端;也可以在靠辊63的两端设置弹性件633(例如弹簧),弹性件633的一端抵接靠辊63,另一端抵接第二安装板61。如此设置,当第一压辊51松开靠辊63时,靠辊63可以弹性复位。
需要说明的时,本申请的靠板62还有一个特点,即转塔200公转,卷绕好电芯的卷针202转到收尾工位准备收尾下料时,另一卷针202转动至卷绕工位,对应该位于卷绕工位的卷针202的靠板62随之转到靠近切刀12的一侧;此时,这个靠板62是沿上下方向B-B设置。也就是说,配合切刀12的靠板62,在配合的工位,是沿上下方向B-B设置的;被位于收尾工位的卷针202牵引的隔膜垂直地抵靠在这个靠板62朝向隔膜切刀装置100一侧,以使隔膜与位于卷绕工位的卷针202的插缝对齐,方便转到卷绕工位的卷针202插出来夹住料卷端的隔膜,以便于开始卷绕形成新的电芯。
本申请的实施例中,贴胶装置包括备胶机构80及贴胶机构90。备胶机构80用于将一定长度的胶带转移至贴胶机构90,贴胶机构90用于将该胶带粘贴于卷针上的电芯的收尾端上,防止电芯松散。
请参见图10所示,一些实施例中,备胶机构80包括移动组件81、移载组件82及压胶组件83。该移动组件81包括固定座811及沿第一方向可移动地连接于固定座811的移载座812。移载组件82包括过胶件821、压胶件822及胶带切刀823。该过胶件821设置于移载座812上,用于供胶带穿过。该压胶件822用于在其移动的过程中将胶带压紧于过胶件821。胶带切刀823用于在其移动的过程中切断穿出过胶件821的胶带。压胶组件83包括第三压辊831,该第三压辊831沿与上述第一方向呈角度的第二方向可移动地连接于固定座811。第三压辊831用于在其沿该第二方向移动的过程中将胶带压紧于贴胶机构90,进一步的将胶带压紧于贴胶机构90的贴胶辊。
其中,在移载座812沿第一方向移动的过程中,过胶件821包括第一位置和第二位置。当过胶件821位于第一位置时,压胶件822可将穿过过胶件821的胶带压紧于过胶件821。当过胶件821处于第二位置时,该过胶件821位于压胶组件83处,以将被压紧于过胶件821的胶带插入第三压辊831和贴胶机构90之间。
上述备胶机构80,实际备胶作业时,首先过胶件821位于第一位置,胶带的端部穿过 过胶件821,然后压胶件822移动直到将胶带压紧于过胶件821。然后,移载座812沿第一方向移动直至过胶件821位于第二位置,此时过胶件821位于压胶组件83处,使得被压紧于过胶件821的胶带的端部插入第三压辊831和贴胶机构90之间,进而第三压辊831移动直至将胶带的端部压紧于贴胶机构90。再然后,压胶件822移动而松开胶带,移载座812沿第一方向移动直至过胶件821回到第一位置,压胶件822移动直至再次将胶带压紧于过胶件821。最后,贴胶机构90吸取胶带,胶带切刀823移动而将胶带切断,切断后的胶带被转移至贴胶机构90。
如此,通过上述备胶机构80能够实现将胶带转移至贴胶机构90,避免了采用人工备胶,自动化程度高,有利于提高生产效率。
在图11所示的实施例中,第一方向为左右方向,第二方向为上下方向。当移载座812由右往左移动时可带动过胶件821由第一位置移动至第二位置。当移载座812由左往右移动时可带动过胶件821由第二位置移动至第一位置。贴胶机构90位于移载组件82和压胶组件83的下方。
具体到实施例中,过胶件821具有一过胶面(图未示)。压胶件822对应于该过胶面设置,胶带由压胶件822与过胶面之间穿过,且压胶件822可朝向过胶面靠近或远离。如此,当需要将胶带压紧于过胶件821时,可使压胶件822朝向靠近过胶面的方向移动直至将胶带压紧于该过胶面。当需要松开胶带时,可使压胶件822朝向远离过胶面的方向移动。
进一步地,过胶件821开设有沿第一方向贯穿其相对两侧的过胶孔(图未示),该过胶孔的一侧壁即为上述过胶面。压胶件822至少部分位于该过胶孔内,以在压胶件822移动的过程中可将胶带压紧于过胶面。

需要说明的是,过胶件821沿第二方向移动的过程中包括移胶位置和第一贴胶位置,当过胶件821位于移胶位置时,过胶件821可在第一位置和第二位置之间(即沿第一方向)移动,以将胶带的端部移送至第三压辊831与贴胶机构90之间而被第三压辊831压紧于贴胶机构90。当过胶件821位于第一贴胶位置时,第三压辊831与过胶件821之间的胶带被转移至贴胶机构90上。

本发明的实施例中,第三压辊831相对固定座811的位置沿第一方向可调节。如此,可根据需求截取不同长度的胶带转移至贴胶机构90上,提高备胶机构80的适用性。
具体到实施例中,压胶组件83还包括调节杆834、压胶座833及调节驱动件832。调节杆834固定安装于固定座811,且与第一方向相平行。压胶座833沿调节杆834可滑动地连接于该调节杆834,调节杆834沿其纵长方向间隔开设有多个安装孔8341,可通过紧 固件与不同的安装孔8341配合,从而将压胶座833紧固于调节杆834。可选地,紧固件可为螺钉。

请一并参见图11、图12及图13所示,本发明的实施例中,备胶机构80还包括废料收卷组件840,该废料收卷组件840用于收卷胶带的废品段。胶带的起头段一般为废品段,因此需要去掉。并且胶带的中间段部分也有可能存在废品段,因此也需要去掉。
废料收卷组件840包括移动座841以及绕自身轴线可转动地设置于移动座841的收卷轴842。移动座841沿与第一方向呈角度的第三方向可移动地设置于固定座811。移动座841沿第三方向移动的过程中,收卷轴842包括收卷位置和避让位置,当收卷轴842处于收卷位置时,收卷轴842位于移载组件82和压胶组件83之间,用于收卷穿出过胶件821的胶带。当收卷轴842处于避让位置时,收卷轴842退出移载组件82和压胶组件83之间。
如此,当穿出过胶件821的胶带为废品时,移动座841沿第三方向移动使得收卷轴842到达收卷位置,对穿出过胶件821的胶带的废品段进行收卷。当胶带的废品段收卷完成,利用胶带切刀823将胶带切断,移动座841沿第三方向移动使得收卷轴842到达避让位置,此时,过胶件821即可在第一位置和第二位置之间移动而实现备胶,且可卸下收卷轴842上的废品胶带或更换新的收卷轴842,为下一次的收卷做准备。
可选地,第三方向垂直于第一方向和第二方向。具体到图11所示的实施例中,第三方向为垂直于纸面的方向。
具体到实施例中,废料收卷组件840还包括旋转轴843及旋转驱动件844。旋转轴843绕自身轴线可转动地连接于移动座841。收卷轴842可拆卸地安装于旋转轴843的一端,以与旋转轴843同步转动而对胶带进行收卷。旋转驱动件844设置于移动座841,且与旋转轴843传动连接,以驱动旋转轴843及安装于旋转轴843上的收卷轴842绕自身轴线旋转。可选地,旋转驱动件844可为电机。
进一步地,收卷轴842可通过球头柱塞8432固定于旋转轴843的一端内。可以理解的是,收卷轴842也可通过本领域所熟知的其它安装方式安装收卷轴842,并不仅限于利用球头柱塞8432的方式,在此不作限定。
具体到实施例中,废料收卷组件840还包括第一平移滑轨845及第一平移驱动件846。第一平移滑轨845设置于固定座811,且沿第三方向纵长延伸。移动座841沿该第一平移滑轨845的纵长延伸方向可滑动地连接于第一平移滑轨845。第一平移驱动件846设置于 固定座811,且与移动座841传动连接,以驱动移动座841沿第一平移滑轨845移动。可选地,第一平移驱动件846可为气缸。进一步地,第一平移滑轨845可通过固定板847安装于固定座811。也就是说,固定板847固定连接于固定座811,第一平移滑轨845固定连接于固定板847。
具体到实施例中,收卷轴842具有夹缝8422,该夹缝8422由收卷轴842远离旋转轴843的一端沿收卷轴842的轴向延伸。当收卷轴842由避让位置移动至收卷位置的过程中,穿出过胶件821的胶带端部插入收卷轴842的夹缝8422中,保证在收卷轴842绕自身轴线转动时能够收卷胶带。
具体到实施例中,备胶机构80还包括检测机构(图未示),该检测机构用于检测胶带是否为废品。检测机构电性连接于控制器,控制器电性连接于第一平移驱动件846和旋转驱动件844,控制器根据检测机构的检测信息控制第一平移驱动件846和旋转驱动件844。当检测机构检测到胶带上的废品段时,第一平移驱动件846在控制器的控制下驱动收卷轴842由避让位置移动至收卷位置,旋转驱动件844在控制器的控制下驱动收卷轴842旋转进行收卷。可选地,检测机构可为光电传感器。
需要说明的是,胶带的起头段一般均为废品段,均需要去除。因此,当穿过过胶件821的胶带为起头段时,控制器控制第一平移驱动件846驱动收卷轴842由避让位置移动至收卷位置,并控制旋转驱动件844驱动收卷轴842旋转,对起头段进行收卷。当起头段收卷完成,胶带切刀823将起头段切断,控制器控制第一平移驱动件846驱动收卷轴842由收卷位置移动至避让位置。
请继续参见图11所示,本发明的实施例中,移动组件81还包括固定安装于固定座811的导向件,移载座812沿该导向件可移动地连接于该导向件。其中,导向件平行于上述第一方向。具体地,该导向件可以为滑轨或者导向杆。

本发明的实施例中,备胶机构80还包括用于放卷输出胶带的放卷组件(图未标)。该放卷组件、上述移载组件82及压胶组件83沿第一方向依次布置,使得放卷组件放卷输出的胶带穿过移载组件82的过胶件821,并在移载组件82的移动过程中将胶带移送至压胶组件83,并利用压胶组件83的第三压辊831压紧于贴胶机构90。
具体到实施例中,放卷组件包括放卷轴851,放卷轴851绕自身轴线可转动地连接于固定座811,用于装载胶带卷并在转动过程中放卷输出胶带。
进一步地,放卷组件还包括缓存组件852,该缓存组件852设置于固定座811且位于放卷轴851的下游侧,用于牵引放卷轴851上的胶带放卷输出而缓存该胶带,并提供给移载组件82。实际备胶作业时,首先缓存组件852牵引放卷轴851上的胶带放卷输出并对该胶带进行缓存。当压胶件822将胶带压紧于过胶件821,且过胶件821由第一位置移动至第二位置的过程中牵引出缓存于缓存组件852的胶带。接着当过胶件821回到第一位置后,缓存组件852再次牵引放卷轴851上的胶带放卷输出并对该胶带进行缓存,为下一次的被过胶件821牵引出胶带作准备。需要说明的是,缓存组件852为本领域较为成熟的现有技术,在此不作赘述。
进一步地,放卷组件还包括位于缓存组件852下游侧的过辊853和夹块854。过辊853安装于固定座811,夹块854对应于过辊853地设置于固定座811,且可朝向该过辊853靠近或远离,以夹紧或松开绕过过辊853的胶带。如此,当缓存组件852缓存胶带时,夹块854朝向靠近过辊853的方向移动而将胶带夹紧于夹块854与过辊853之间,以便于缓存组件852缓存胶带。当需要过胶件821牵引出缓存组件852的胶带时,夹块854朝向远离过辊853的方向移动,从而松开绕过该过辊853的胶带,以便于缓存组件852内的胶带被过胶件821牵引输出。
进一步地,放卷组件还包括安装于固定座811的夹胶驱动件855,夹块854安装于该夹胶驱动件855的驱动端,以使夹胶驱动件855可驱动夹块854朝向过辊853靠近或远离。
请参见图14及图15所示,一些实施例中,贴胶机构90包括贴胶组件(图未标)及平移组件920。贴胶组件包括贴胶辊911及贴胶辊支架912,该贴胶辊911绕自身轴线可转动地连接于贴胶辊支架912。平移组件920包括支撑座921及安装于支撑座921的第二平移驱动件922。贴胶辊支架912沿第四方向可移动地连接于支撑座921,且与第二平移驱动件922传动连接。在图14所示的实施例中,第四方向即为左右方向。
其中,在贴胶辊支架912沿第四方向移动地过程中,贴胶辊911包括备胶位置和第二贴胶位置。当贴胶辊911位于备胶位置时,备胶机构可将胶带转移至贴胶辊911,当贴胶辊911位于第二贴胶位置时,贴胶辊911可与卷针上的电芯相抵,以将贴胶辊911上的胶带粘贴于该电芯上,胶带用于将电芯的收尾端贴附在电芯上,防止电芯松散。
上述贴胶机构90,首先贴胶辊支架912沿第四方向移动(即在图14所示的实施例中的由左至右的方向),使得贴胶辊911到达备胶位置,此时备胶机构80将胶带转移至贴胶 辊911上。然后贴胶辊支架912沿第四方向(即在图14所示的实施例中的由右向左的方向)移动,使得贴胶辊911到达第二贴胶位置,此时贴胶辊911可与位于收尾工位的卷针202上的电芯相抵。再然后贴胶辊911和装载电芯的卷针202均绕自身轴线转动,从而将胶带粘贴于电芯。
现有技术中,贴胶辊安装于摆动结构上,通过摆动结构带动贴胶辊在备胶机构和卷绕机构之间来回摆动。由于现有技术中采用摆动的方式,摆动结构的摆臂需要设计的较长,需要的扇形摆动空间较大,导致贴胶机构所需要占用的空间较大,不利于电池生产设备布局的优化。与现有技术相比,本实施例中的贴胶机构90利用平移组件920的第二平移驱动件922驱动贴胶辊支架912和贴胶辊911在备胶位置和第二贴胶位置之间来回移动,从而实现备胶和贴胶,大大减小了贴胶机构90所需要占用的空间,有利于对电池生产设备进行布局优化。
需要说明的是,现有技术中采用摆动的方式,由于摆臂的转动惯量比较大,为了避免对电芯造成较大的冲击而损坏电芯,因此摆动结构的旋转速度不能太快,进而影响贴胶效率。与现有技术相比,本实用新型中的贴胶机构90采用直线移动的方式,有利于提高贴胶速度,即提高贴胶效率。
还需要说明的是,具体到一个实施例中,贴胶辊911和卷针202的轴向相平行。上述第一方向平行于贴胶辊911的轴向,上述第二方向、第三方向及第四方向均垂直于卷针202的轴向。
本发明的实施例中,贴胶机构90还包括摆动组件(图未示),该摆动组件包括滑座931、摆动旋转轴932、摆臂933及摆动驱动件934。滑座931沿第四方向可移动地连接于支撑座921,且与第二平移驱动件922传动连接,从而第二平移驱动件922可驱动滑座931沿第四方向移动。
摆动旋转轴932可绕自身轴线可转动地连接于滑座931,摆臂933的一端固定连接于摆动旋转轴932,摆臂933的另一端固定连接于贴胶辊支架912。摆动驱动件934包括固定端(图未标)及可相对固定端伸缩的伸缩端(图未标)。固定端和伸缩端其中一个铰接连接于贴胶辊支架912,其中另一个铰接连接于滑座931,从而通过摆动驱动件934的伸缩驱动贴胶辊911及贴胶辊支架912绕摆动旋转轴932转动。也就是说,摆动驱动件934为贴胶辊911及贴胶辊支架912绕摆动旋转轴932的转动提供驱动力。可选地,摆动驱动件934可为气缸。
实际贴胶作业时,首先,第二平移驱动件922驱动滑座931沿第四方向移动而带动贴胶辊911移动至备胶位置,备胶机构80将胶带转移至贴胶辊911。然后,第二平移驱动件 922驱动滑座931沿第四方向移动而带动贴胶辊911移动至第二贴胶位置。再然后,摆动驱动件934驱动摆动旋转轴932绕自身轴线转动,从而带动贴胶辊911朝向卷针202上的电芯转动直到贴胶辊911抵持在电芯上。最后,贴胶辊911和卷针202均绕自身轴线转动,从而将贴胶辊911上的胶带粘贴于电芯上。
如此,本实施例中的贴胶组件的贴胶辊911沿第四方向在备胶位置和第二贴胶位置之间移动(即直线移动),且在摆动组件的带动下位于第二贴胶位置的贴胶辊911绕摆动旋转轴932转动,直至贴胶辊911与电芯相抵接。摆动组件带动贴胶辊911的摆动幅度较小,其目的是为了将贴胶辊911与电芯抵接。由于直接采用直线移动使得贴胶辊911与电芯接触,直线移动的速度较快时对电芯的冲击力较大,容易造成电芯的损坏。为了进一步避免电芯的损坏,在本实施例中贴胶辊911首先直线移动至靠近电芯的位置(即第二贴胶位置),然后再摆动至与电芯相抵接。即本实施例中的贴胶机构90采用了直线运动和摆动运动相接合的方式实现了贴胶作业,在减小贴胶机构90所需要占用的空间的基础上,有利于减小对电芯的冲击,避免损坏电芯,且保证了贴胶辊911的灵活性,使得贴胶动作顺畅,有利于提高贴胶质量。
可以理解的是,在本实施例中,贴胶辊911移动至第二贴胶位置时贴胶辊911靠近电芯,但并不与电芯接触,从而预留贴胶辊911绕摆动旋转轴932摆动至抵靠在电芯上的空间。
具体到实施例中,摆动组件还包括在外力的作用下可伸缩的平衡件935,该平衡件935连接于贴胶辊支架912和滑座931之间。也就是说,该平衡件935一端连接于贴胶辊支架912,另一端连接于滑座931。该平衡件935用于平衡贴胶辊911及贴胶辊支架912的重力,且在摆动驱动件934提供的动力作用下驱动贴胶辊911及贴胶辊支架912绕摆动旋转轴932来回摆动的过程中,该平衡件935适应性的伸缩。也就是说,平衡件935并不为贴胶辊911的摆动提供动力,仅仅用于平衡贴胶辊911及贴胶辊支架912的重力。如此,该平衡件935的设置平衡了贴胶辊911及贴胶辊支架912的重力,便于通过控制摆动驱动件934来控制贴胶辊911对电芯的压力(平衡件935消除了贴胶辊911及贴胶辊支架912等自身重力对贴胶辊911对电芯的压力的影响),即使得贴胶辊911对电芯的压力容易控制。可选地,该平衡件935可为气缸或弹簧等。优选地,该平衡件935为气缸,且铰接连接于贴胶辊支架912和滑座931之间。
进一步地,滑座931设置有铰接座9312,摆动驱动件934及平衡件935的一端均铰接连接于该铰接座9312,以便于摆动驱动件934及平衡件935的安装。
贴胶辊支架912背离贴胶辊911的一侧固定连接有驱动块9121,摆动驱动件934及平 衡件935的另一端均铰接连接于该驱动块9121,以方便摆动驱动件934及平衡件935的安装。
具体到实施例中,支撑座921上设置有沿上述第四方向纵长延伸的第二平移滑轨924。滑座931沿第二平移滑轨924的纵长延伸方向可移动地连接于第二平移滑轨924。如此,第二平移滑轨924的设置使得滑座931沿第四方向的移动更加平稳。
具体到实施例中,平移组件920还包括平移丝杆923及平移丝杆螺母。该平移丝杆923绕自身轴线可转动地连接于支撑座921,且与第二平移驱动件922传动连接。该平移丝杆923平行于上述第四方向。平移丝杆螺母螺纹连接于平移丝杆923,且与滑座931固定连接。如此,第二平移驱动件922驱动平移丝杆923绕自身轴线转动,从而带动平移丝杆螺母及固定连接于平移丝杆螺母的滑座931沿平移丝杆923(即第四方向)移动。可选地,平移组件920还包括滑动块925,滑动块925沿第二平移滑轨924可滑动地设置于该第二平移滑轨924。滑座931固定连接于滑动块925,即滑座931通过滑动块925设置于第二平移滑轨924。平移丝杆923转动从而驱动丝杆螺母沿平移丝杆923移动,进而带动滑座931沿第二平移滑轨924滑动。
一些实施例中,贴胶组件还包括贴胶旋转轴913、贴胶驱动件(图未示)、第一传动结构914及第二传动结构(图未标)。贴胶旋转轴913绕自身轴线可转动地连接于滑座931,贴胶驱动件安装于该滑座931。第一传动结构914传动连接于贴胶驱动件与贴胶旋转轴913之间,以使贴胶驱动件可驱动贴胶旋转轴913绕自身轴线转动。第二传动结构传动连接于贴胶旋转轴913与贴胶辊911之间,以使贴胶旋转轴913可带动贴胶辊911绕自身轴线转动。可选地,贴胶驱动件可为电机。
具体到实施例中,摆动旋转轴932可为空心轴,并套设于贴胶旋转轴913外,且摆动旋转轴932相对贴胶旋转轴913可转动。如此,将摆动旋转轴932与贴胶旋转轴913相互套设,使得结构更加紧凑,进一步减小贴胶机构90所需要占用的空间。进一步地,摆动旋转轴932与贴胶旋转轴913之间设置有轴承。也就是说,贴胶旋转轴913外套设有轴承,摆动旋转轴932套设于该轴承上。如此,实现了贴胶旋转轴913与摆动旋转轴932可相对绕各种轴线可转动。
具体到实施例中,第一传动结构914包括第一主动轮9141、第一从动轮9143及第一传动带9142。第一主动轮9141安装于贴胶驱动件的输出轴,以与贴胶驱动件的输出轴同步转动。第一从动轮9143安装于贴胶旋转轴913的一端,以与贴胶旋转轴913同步转动。第一传动带9142套设于第一主动轮9141和第一从动轮9143之间,以使第一从动轮9143可随第一主动轮9141转动。如此,贴胶驱动件的输出轴输出的旋转运动依次通过第一主 动轮9141、第一传动带9142及第一从动轮9143传递至贴胶旋转轴913,从而实现贴胶驱动件驱动贴胶旋转轴913旋转。
具体到实施例中,第二传动结构包括第二主动轮9151、第二传动带9152及第二从动轮9153。第二主动轮9151安装于贴胶旋转轴913的另一端,以与贴胶旋转轴913同步转动。也就是说,第二主动轮9151与第一从动轮9143分别安装于贴胶旋转轴913的相对两端。第二从动轮9153安装于贴胶辊911,以与贴胶辊911同步转动。第二传动带9152套设于第二主动轮9151与第二从动轮9153之间,以使第二从动轮9153可随第二主动轮9151转动。如此,贴胶旋转轴913可依次通过第二主动轮9151、第二传动带9152及第二从动轮9153带动贴胶辊911转动。
具体到实施例中,贴胶驱动件可通过安装支座9314安装于滑座931,从而便于贴胶驱动件的安装及第一传动结构的布置。
本发明的实施例中,贴胶组件还包括调节块9162及固定块9161,该调节块9162固定连接于贴胶辊支架912,贴胶辊911的一端可转动连接于贴胶辊支架912,另一端可转动地连接于固定块9161。固定块9161设置于调节块9162,且相对调节块9162的位置可调节。如此,可通过调节固定块9161相对调节块9162的位置来调节贴胶辊911的位置,以保证贴胶辊911与安装电芯的卷针202的平行度,有利于提高贴胶质量。
具体到实施例中,贴胶组件还包括锁紧件9163及调节件9164。固定块9161开设有至少两个腰型孔a,每一腰型孔a穿设有一锁紧件9163,该锁紧件9163的一端穿过一腰型孔a并螺纹连接于调节块9162,以将固定块9161锁紧固定于调节块9162。调节件9164的一端沿与腰型孔a的纵长方向相平行的方向穿设于调节块9162,并用于与固定块9161相抵,且调节件9164与调节块9162螺纹连接。如此,当贴胶辊911与卷针202的平行度不能满足贴胶需求,而需要对贴胶辊911的位置进行调整时,可拧松锁紧件9163,然后旋拧调节件9164而推动固定块9161沿腰型孔a移动,达到调节贴胶辊911的目的,使得贴胶辊911与卷针202的平行度满足贴胶要求。可选地,锁紧件9163可为螺栓。调节件9164可为螺杆。
进一步地,调节件9164上螺纹连接有防松螺母(图未标),该防松螺母位于调节块9162背离固定块9161的一侧。如此,防松螺母的设置有效改善了在贴胶作业过程中调节件9164松动的问题。
本发明的实施例中,贴胶辊911的周侧表面开设有多个吸附孔,每一吸附孔均与外部真空源连通。如此,当备胶机构80将胶带转移至贴胶辊911上时,可利用对应的吸附孔对胶带进行吸附,避免胶带掉落。可以理解的是,该真空源可为气泵。
需要说明的是,一般的胶带包括相对的带胶面及非带胶面。胶带被备胶机构80转移至贴胶辊911上时,胶带的非带胶面与贴胶辊911的周侧表面接触,从而被吸附。
具体到实施例中,贴胶辊911具有一与外部真空源连通的内腔,每一吸附孔均连通于该内腔。如此,每一吸附孔通过该内腔与外部真空源连通。
具体到实施例中,各个吸附孔均匀布设于贴胶辊911的周侧表面,从而有利于提高对胶带的吸附效果。
请参见图16所示,本申请的实施例中,下料装置包括升降组件72和下料组件73。升降组件72设于位于收尾工位的卷针202的旁侧。下料组件73位于升降组件72靠近该卷针202的一侧。下料组件73包括相对间隔设置的第一端731和第二端732,至少第一端731与升降组件72滑动连接。
下料组件73的第一端731与第二端732之间的间隔方向沿卷针202的第一径向方向(如图16中箭头X所示,下同)设置。也就是说,本实施例的下料组件73对应卷针202上所卷绕电芯的直径设计,而不同于传统下料机构对应电芯的长度设计,因此本实施例允许下料组件73在第一径向方向上的尺寸可以设计得更小,从而有利于提高下料组件73的可靠性以及稳定性,以保障电芯下料的稳定进行,避免了传统悬臂梁形式的下料组件在第一径向方向上的尺寸过大而发生过度下挠等影响结构可靠性以及稳定性的问题。
升降组件72用于带动下料组件73沿卷针202的第二径向方向(如图16中箭头Y所示,下同)移动,进而带动下料组件73朝向或远离卷针202移动,以在下料组件73朝向卷针202移动后对电芯进行下料,并在下料后携带电芯远离卷针202移动。
需要说明的是,本实施例的升降组件72远离下料组件73的移动路径设置。具体地,下料组件73位于卷针202的下方,升降组件72位于卷针202和下料组件73的旁侧。如此一来,可以避免升降组件72占据卷针202下方的空间,避免占据下料组件73的活动空间,从而能够降低对卷针202设置高度的要求,使得卷针202的设计可以更加灵活。
进一步地,下料组件73可以仅其第一端731与升降组件72滑动连接,即下料组件73为悬臂梁结构,其第二端732为悬臂梁结构的自由端,如图16所示。当然,在本申请的其它实施例中,下料组件73的第一端731和第二端732可以分别滑动连接一升降组件72,在此不作限定。
请继续参阅图16所示。在一实施例中,升降组件72包括升降安装板721、第二升降驱动件722以及升降导向件723。升降安装板721设于卷针202的旁侧且平行于卷针202的轴向设置。升降导向件723设于升降安装板721上且位于升降安装板721靠近卷针202 的一侧,升降导向件723沿第二径向方向设置。下料组件73滑动支撑于升降导向件723上,并连接第二升降驱动件722,第二升降驱动件722用于驱动下料组件73沿升降导向件723移动,进而驱动下料组件73沿第二径向方向朝向或远离卷针202移动。
需要说明的是,卷针202设置于基座201的一侧面上。升降安装板721的延伸面垂直于基座201安装有41卷针的一侧面的延伸面,使得升降安装板721和基座201所限定出的电芯下料的作业空间为开放式,能够方便工作人员进行设备安装以及维护。而传统下料机构中,升降组件的安装板通常和卷针202所处的基座201相对设置,导致工作人员必须进入升降组件72的安装板与卷针202所处的基座201之间的空间中才可进行设备安装以及维护,致使工作人员不便于进行设备安装以及维护。
请参阅图16-17。在一实施例中,下料组件73包括夹料组件74以及送料组件75。夹料组件74用于夹持电芯,并在电芯与卷针202分离后,将电芯释放于送料组件75上,以由送料组件75输送至下料区76,进而完成电芯的下料作业。
具体地,第二升降驱动件722包括第一驱动件7221和第二驱动件7222。升降导向件723包括第一升降导向件7231和第二升降导向件7232。夹料组件74滑动支撑于第一升降导向件7231上,并连接第一驱动件7221,第一驱动件7221用于驱动夹料组件74沿第一升降导向件7231移动。送料组件75滑动支撑于第二升降导向件7232上,并连接第二驱动件7222,第二驱动件7222用于驱动送料组件75沿第二升降导向件7232移动。
可选地,第一驱动件7221和第二驱动件7222可以是丝杆等元件,夹料组件74和送料组件75上分别设有与丝杆配合的螺母。丝杆由伺服电机或步进电机等驱动,并通过丝杆和螺母之间的配合,带动夹料组件74沿第一升降导向件7231移动以及带动送料组件75沿第二升降导向件7232移动。
当然,在本申请的其它实施例中,第一驱动件7221和第二驱动件7222也可以采用电缸、直线电机以及皮带传送机构等形式,驱动夹料组件74和送料组件75朝向或远离卷针202移动。
需要说明的是,本实施例中夹料组件74和送料组件75分别由不同的升降驱动件722和升降导向件723驱动其移动,使得夹料组件74和送料组件75之间的移动控制相互独立、互不干涉,从而能够更灵活地调整夹料组件74和送料组件75的位置,以便电芯下料作业的开展。
请参阅图16、18-19。图18是图16所示下料装置的夹料组件一实施例的俯视结构示意图,图119是图18中A区域的放大结构示意图。由于夹爪组件742的两个夹爪7422具有相同的结构,因此图19仅示出了夹爪组件742的其中一个夹爪7422部分的结构。
在一实施例中,夹料组件74包括夹爪安装板741以及设于夹爪安装板741上的夹爪组件742,夹爪组件742用于夹持电芯,以便电芯和卷针202分离。
在一实施例中,夹料组件74还包括设于夹爪安装板741上的第一连接板驱动件743,夹爪组件742包括第一连接板7421,并且第一连接板7421滑动支撑于夹爪安装板741上,并能够在第一连接板驱动件743的驱动下沿第一径向方向移动,从而控制整个夹爪组件742在夹爪安装板741上朝向或远离卷针202移动,进而调节夹爪组件742在夹爪安装板741上的位置,以适配卷针202,便于夹爪组件742更好地夹持电芯,进行下料。
夹料组件74还可以包括连接板导向件744,连接板导向件744设于夹爪安装板741上且沿第一径向方向延伸,夹爪组件742的第一连接板7421和连接板导向件744滑动连接,进而引导第一连接板7421沿第一径向方向的移动。
进一步地,夹料组件74包括彼此间隔的两组夹爪组件742。其中一组夹爪组件742对应第一端731,另一组夹爪组件742对应第二端732,并且两组夹爪组件742的间隔方向沿第一径向方向设置。第一连接板驱动件743驱动两组夹爪组件742的第一连接板7421沿第一径向方向彼此相向或相背移动。通过上述方式,本实施例允许根据电芯的直径调节两组夹爪组件742之间的间距,以便两组夹爪组件742分别从电芯在第一径向方向上相对的两侧配合夹持电芯,以对卷绕于卷针202上的电芯进行下料。并且设置两组夹爪组件742能够使得夹料组件74更稳定地夹持电芯,保障电芯下料作业的稳定进行。其中,由于从卷针202上卸下的电芯通常呈圆柱状,其横截面为圆形,电芯放置于送料组件75后容易自发滚动,导致电芯容易从送料组件75上脱落,进而导致电芯损坏等诸多问题。因此本实施例当两组夹爪组件742夹持住电芯后,可以控制两组夹爪组件742彼此相背移动一定距离,以拉伸电芯,将电芯的横截面拉伸为椭圆形,使得电芯在送料组件75上不易自发滚动,进而降低电芯从送料组件75上脱落的风险。
具体地,两组夹爪组件742的第一连接板7421分别滑动支撑于连接板导向件744,第一连接板驱动件743分别和该两组夹爪组件742连接,以驱动两组夹爪组件742的第一连接板7421沿第一径向方向彼此相向或相背移动。其中,两组夹爪组件742在第一径向方向上间隔设置,当夹料组件74夹持电芯时,卷针202及其上的电芯在夹爪安装板741上的正投影位于两组夹爪组件742之间,因而可以通过根据电芯的直径调节两组夹爪组件742之间的间距,以便两组夹爪组件742配合夹持电芯。如此一来,由于不同型号的卷针202所卷绕而成的电芯规格不同,本实施例的夹料组件74可以根据电芯的直径调节两组夹爪组件742之间的间距,以便两组夹爪组件742配合夹持电芯,因此能够适配不同型号的卷针202,具有良好的兼容性。
可选地,第一连接板驱动件743可以是丝杆等元件,两组夹爪组件742的第一连接板7421上设有与丝杆螺纹配合的螺母,丝杆由电机驱动,以通过丝杆和螺母的配合驱动两组夹爪组件742彼此相向或相背移动。其中,丝杆上对应两组夹爪组件742的螺纹旋向相反,进而使得通过丝杆的轴向自转,驱动两组夹爪组件742彼此相向或相背移动。
在一实施例中,夹爪组件742还包括滑动连接于第一连接板7421上的夹爪7422,夹爪7422能够在第一连接板7421上沿卷针202的轴向移动,以夹持电芯。
夹爪组件742还包括第二连接板7423和第二连接板驱动件7424,夹爪7422设于第二连接板7423上,第二连接板7423滑动支撑于第一连接板7421上且能够在第二连接板驱动件7424的驱动下沿卷针202的轴向移动,进而使夹爪7422能够沿卷针202的轴向移动。
夹爪7422包括相对设置的第一抵压件74221和第二抵压件74222,夹爪组件742还包括第三连接板7425和第三连接板驱动件7426,第一抵压件74221设于第三连接板7425上,第二抵压件74222固设于第二连接板7423上,第三连接板7425滑动支撑于第二连接板7423上,并能够在第三连接板驱动件7426的驱动下沿第一径向方向移动,进而使得第一抵压件74221和第二抵压件74222分别从电芯的内外两侧夹持电芯的侧壁。
具体地,夹爪组件742包括滑动连接于第一连接板7421上且沿卷针202的轴向间隔设置的两个夹爪7422,两个夹爪7422分别能够在第一连接板7421上沿卷针202的轴向彼此相向或相背移动,以从电芯在卷针202轴向上相对设置的两侧配合夹持电芯。
夹爪组件742还包括两个第二连接板7423和至少一个第二连接板驱动件7424,各夹爪7422分别设于一个第二连接板7423上,第二连接板7423滑动支撑于第一连接板7421上且能够在第二连接板驱动件7424的驱动下沿卷针202的轴向移动,进而使两个夹爪7422能够彼此相向或相背移动。
可选地,第二连接板驱动件7424可以是气缸或液压缸等,第二连接板驱动件7424可以固设于第一连接板7421上,并且第二连接板驱动件7424的伸缩端连接第二连接板7423,进而驱动第二连接板7423移动。并且,本实施例中可以针对各第二连接板7423分别设置一个第二连接板驱动件7424,各第二连接板驱动件7424驱动对应的第二连接板7423移动。
进一步地,夹爪7422包括相对设置的第一抵压件74221和第二抵压件74222,夹爪组件742还包括两个第三连接板7425和至少一个第三连接板驱动件7426,两个夹爪7422的第一抵压件74221分别设于一个第三连接板7425上,两个夹爪7422的第二抵压件74222分别固设于一个第二连接板7423上,各第三连接板7425分别滑动支撑于对应的第二连接板7423上,并能够在第三连接板驱动件7426的驱动下沿第一径向方向移动,进而使得第一抵压件74221和第二抵压件74222分别从电芯的内外两侧夹持电芯的侧壁。
可选地,第三连接板驱动件7426与第二连接板驱动件7424同理,其可以是气缸或液压缸等。第三连接板驱动件7426可以固设于第二连接板7423上,并且第三连接板驱动件7426的伸缩端连接第三连接板7425,进而驱动第三连接板7425移动。并且,本实施例中可以针对各第三连接板7425分别设置一个第三连接板驱动件7426,各第三连接板驱动件7426驱动对应的第三连接板7425移动。
并且,第一连接板7421上可以设有对应第二连接板7423的导轨结构,第二连接板7423与第一连接板7421上的导轨结构滑动连接,以引导第二连接板7423在第一连接板7421上的移动。与上述同理,第二连接板7423上也可以设有对应第三连接板7425的类似导轨结构,第三连接板7425与第二连接板7423上的导轨结构滑动连接,以引导第三连接板7425在第二连接板7423上的移动。
需要说明的是,在本实施例下料装置的实际使用场景中,卷针202的第一径向方向和卷针202的轴向沿水平方向设置且彼此垂直,卷针202的第二径向方向沿竖直方向设置。
请继续参阅图16。在一实施例中,送料组件75包括送料安装板751、驱动轮752以及传送带753,送料安装板751滑动支撑于第二升降导向件7232上,并连接第二驱动件7222,驱动轮752设于送料安装板751上,传送带753套设于驱动轮752外周,驱动轮752用于带动传送带753上的电芯随传送带753移动。
下料区76设置有合格品收集区761和废品收集区762,合格品收集区761和废品收集区762沿送料组件75的移动方向依次设置,以在送料组件75在第二驱动件7222的驱动下远离卷针202移动的过程中,通过驱动轮752带动传送带753将合格品电芯传送至合格品收集区761,或将废品电芯传送至废品收集区762。合格品收集区761同样也可以是传送带的形式,以将合格品电芯传送至下一生产环节。而废品收集区762可以是一废料盒,用来收集废品电芯,最后统一进行处理。
进一步地,夹料组件74的夹爪安装板741上对应电芯的部位,例如夹爪安装板741的中部,设有缺口7411,送料组件75用于输送电芯的驱动轮752以及传送带753穿过夹爪安装板741上的缺口7411,以供夹料组件74将电芯释放于传送带753上,并由驱动轮752带动传送带753输送电芯。
以下以图16-19展示的下料装置为例,大致阐述本申请的实施例所提供下料装置的工作过程:
图18展示了下料装置的夹料组件74包括两组夹爪组件742,并且各夹爪组件742分别包括两组夹爪7422,以从电芯的四个不同方位夹持电芯,以便于电芯和卷针202分离。

综上所述,本申请提供的电芯的下料装置,其下料组件包括相对间隔设置的第一端和第二端,其中至少第一端与升降组件滑动连接,该升降组件带动下料组件沿卷针的第二径向方向移动,进而带动下料组件朝向或远离卷针移动,以对电芯进行下料。下料组件的第一端与第二端之间的间隔方向沿卷针的第一径向方向设置,即下料组件对应卷针上所卷绕电芯的直径设计,而不同于传统下料机构对应电芯的长度设计,因此本申请允许下料组件在第一径向方向上的尺寸可以设计得更小,从而有利于提高电芯下料装置的可靠性以及稳定性,以保障电芯下料的稳定进行,避免了悬臂梁形式的下料组件在第一径向方向上的尺寸过大而发生过度下挠等影响结构可靠性以及稳定性的问题。
