电池(Battery)指盛有电解质溶液和金属电极以产生电流的杯、槽或其他容器或复合容器的部分空间,能将化学能转化成电能的装置。随着科技的发展,拥有携带方便、充放电操作简便易行、长时间稳定供电等优点的电池被广泛应用于汽车、家电、航空航天等领域中。
电池的极耳部是从电芯中将正负极引出壳体的金属导电体,因此在电池的装配过程中,电池的极耳部需要引出壳体外部,以作为电池进行充放电时的接触点。但是在电池的装配过程中,电池的电芯在装配壳体时,极耳部容易弯折在壳体内部而无法延伸出壳体外,因此导致电池的装配制备工艺的难度较高,且电池的制备良品率较低。

两个导向板2631彼此拼合时能够围合形成定位孔264,壳体固定机构210带动壳体10下降时能够被两个导向板2631导向,壳体10的开口端12对准电极组件20。而两个导向板2631彼此分离时可远离壳体10,以使得固定执行机构212可以夹持壳体10继续套入电极组件20,完成电极组件20的入壳流程。
利用两个导向板2631来形成定位孔264可以简化入壳装置2,能够减少入壳装置2的成本,而且也方便定位驱动机构265控制驱动两个导向板2631形成定位孔264,或者彼此分离而远离壳体10。
在一些实施例中,如图8至图9所示,每个导向板2631可以具有用于围设定位孔264的部分孔壁,部分孔壁可以包括沿预设装配方向上连接的第一孔壁段2632和第二孔壁段2633,第一孔壁段2632和第二孔壁段2633的连接处形成承缘部2634。至少两个导向板2631在彼此拼合时,其承缘部2634彼此拼接成朝向壳体固定机构210的承台面2635,承台面2635可以用于抵接壳体10的开口端12,以能够对壳体10进行定位。
在围设定位孔264的部分孔壁上设置承缘部2634以形成承台面2635,可以使得承台面2635可以围合定位孔264,以使得壳体10的开口端12抵接在承台面2635时,开口端12能够对准定位孔264,以使得壳体10与导向板2631下方的电极组件20对准。
可选地,定位孔264可以设置成供电极组件20从至少两个导向板2631背离承台面2635的另一侧穿设于定位孔264内,以能够对电极组件20进行定位。
具体地,在壳体10的开口端12抵接承台面2635后,至少两个导向板2631在定位驱动机构265的驱动跟随壳体10一同沿着预设装配方向下降,而后定位孔264背离壳体10的一侧靠近电极组件20,电极组件20可被定位孔264定位导向,并穿过定位孔264,从而进一步通过开口端12穿入壳体10的容纳腔11内,从而可以提高电极组件20的入壳的准确度以及效率。
在一些实施例中,定位驱动机构265可以设置成在极耳部引导机构220接触极耳部21后驱动至少两个导向板2631彼此分离,以撤离承台面2635对开口端12的止挡,使得壳体固定机构210能够将壳体10进一步套入电极组件20。
可选地,在极耳部引导机构220接触极耳部21时,壳体10还未完全套入电极组件20,而在极耳部引导机构220接触极耳部21后,壳体10会在第一升降驱动机构240的驱动下进一步沿着预设装配方向向电极组件20的方向运动以进一步完全套入电极组件20,在此过程中至少两个导向板2631不仅会止挡开口端12,还会与夹持固定电极组件20的承载机构300造成相互止挡,因此驱动后至少两个导向板2631彼此分离的设置,可以使得壳体10能够顺利套入电极组 件20以完成电极组件20的入壳步骤。
在一些实施例中,如图9所示,定位导向板263的两侧可分别设置有导向斜面2636,导向斜面2636往靠近定位孔264的方向上呈聚拢状设置,以引导开口端12和电极组件20移动进入定位孔264。
具体地,定位导向板263在预设装配方向上面对壳体10的一侧以及面对承载机构300的一侧分别设置有导向斜面2636,两侧的导向斜面2636皆可围绕定位孔264并且与定位孔264的部分孔壁相连接,导向斜面2636的延伸方向与预设装配方向呈现锐角设置,以使得导向斜面2636往靠近定位孔264的方向上呈聚拢状设置。
在壳体10向至少两个导向板2631靠近并接触导向板2631的过程中,若壳体10原本的位置准确,壳体10的开口端12可直接抵接于承台面2635,若壳体10的位置发生偏移,并没有对准承台面2635,在接触至少两个导向板2631后可以由导向斜面2636导向,以定位导向壳体10,使得壳体10移动对准承台面2635以及定位孔264。
电极组件20也是同样通过导向板2631另一侧的导向斜面2636来被定位对准定位孔264,方便电极组件20移动进入定位孔264内,以完成电极组件20的入壳步骤。
在一些实施例中,如图10所示,承载机构300可以包括承载夹具320以及夹具驱动机构330,夹具驱动机构330与承载夹具320相连接。
承载夹具320可用于夹持电极组件20,夹具驱动机构330可用于驱动承载夹具320在夹持状态和卸载状态之间切换。夹具驱动机构330设置成在壳体10套入电极组件20的过程中驱动承载夹具320切换成卸载状态,以避让壳体固定机构210。
进一步地,承载夹具320也可以夹持底盖30,以使得电极组件20与底盖30在依次叠加后能够相对固定。输送线310在输送承载夹具320时可以同时带动输送由承载机构300夹持的电极组件20以及底盖30,从而使得输送线310在输送电极组件20与底盖30过程中,电极组件20和底盖30不易发生移位甚至掉落的情况。
而且将夹具驱动机构330设置成在壳体10套入电极组件20的过程中驱动承载夹具320处于卸载状态,可以使得夹具驱动机构330不易与壳体10相互阻挡,壳体10能够顺利套入电极组件20,壳体10的开口端12能够抵接于底盖30,以完成电极组件20的入壳步骤。
可选地,夹具驱动机构330设置成在极耳部引导机构220接触极耳部21之后,在壳体10进一步套入电极组件20的过程中驱动承载夹具320切换成卸载状态。如此设置,使得在极耳部引导机构220接触极耳部21的过程中,承载夹具320依然在夹持电极组件20,以进一步固定电极组件20,以免极耳部21引导组件碰撞到电极组件20使得电极组件20发生移位。
基于上述电池1以及电池1的入壳装置2的基本结构,以下为电池组装系统实施例对电池组装系统的示例性描述。
电池组装系统可以包括如上文所述的入壳装置2。电池组装系统还可以包括输送设备和组装设备。输送设备可用于向组装设备的各个工位输送待组装结构以及承载机构300。组装设备的工位可至少包括极耳部焊接装置、穿极耳部装置、极柱焊接装置和底盖焊接装置。

其中,极耳部焊接装置可用于将电极组件20的多个极耳片焊接形成极耳部21。入壳装置2用于将电极组件20从开口端12装入设置壳体10。穿极耳部装置用于在电极组件20装入壳体10时夹持极耳部21穿过通孔14。极柱焊接装置用于将穿过通孔14的极耳部21与极柱15背离容纳腔11的一侧焊接。底盖焊接装置用于将底盖30与壳体10的开口端12焊接。
具体地,极耳部焊接装置目的可为实现极耳片预焊后形成极耳部21,可选为超声焊接设备,其能保证极耳片在夹紧的稳定状态下进行焊接即可。入壳装置可为推送机构或夹持机构,能稳定地使电极组件20向壳体10的开口端12运动,并通过开口端12进入容纳腔11即可。同理,穿极耳部装置可采用夹持结构或引导结构,能引导极耳部21顺利穿过通孔14而不与壳体10发生干涉即可。极柱焊接装置目的在于实现极耳部21和极柱15的焊接,可选为激光焊接设备。底 盖焊接装置目的在于实现底盖30和壳体10的开口端12的周向边缘焊接,也为激光焊接设备。
另外,组装设备不限于包括极耳部焊接装置、入壳装置、穿极耳部装置、极柱焊接装置和底盖焊接装置。示例性地,当电极组件20的数量为多个时,例如为两个时,组装设备还可以包括配对装置,配对装置可以用于堆叠设置多个电极组件20,使两个所述电极组件20的极耳部大致相对,以便于输送结构能将配合对后的电极组件20输送到极耳部焊接装置进行极耳部的焊接,以方便极耳部21的形成。再示例性地,为了保证电池1组装过程的可靠性,还可以在任意相邻两个工位之间加入除尘、NG检测工位等,本实施例不做限定。
以上述的电池1实施例以及电池1的入壳装置2为例,以下示例性地描述电池1的装配方法,如图11所示,该装配方法包括以下步骤:
S100:分别固定壳体以及电极组件。
可选地,可以先将底盖30放置于承载机构300上,而后将电极组件20放置于底盖30上,使得电极组件20以及底盖30在预设装配方向上依次层叠,且电极组件20的极耳部21与底盖30相背。进一步地,承载夹具320夹持固定电极组件20以及底盖30,输送线310进一步将承载夹具320以及电极组件20和底盖30一同输送至装壳机构200所对应的入壳工位处。
而装壳机构200可以通过第一升降驱动机构240来驱动第一支撑架211上的固定执行机构212来固定壳体10,且使得壳体10的开口端12在预设装配方向上朝向承载机构300上的电极组件20。
S200:控制壳体相对于承载机构下降,以在下降的过程中将壳体通过开口端套入电极组件。
在一些实施例中,在控制壳体10相对于承载机构300下降之前,包括步骤:从壳体10一侧经通孔14穿入容纳腔11内夹持极耳部21。
在一些实施方式中,先通过第二升降驱动机构250驱动极耳部引导机构220的第二支撑架221沿预设装配方向相对于第一支撑架211下降,以使得设置于第二支撑架221的引导执行机构222能够相对于第一支撑架211上的固定执行机构212下降,从而使得极耳部引导机构220的引导执行机构222从壳体10一侧经通孔14穿入容纳腔11内,以为引导极耳部21穿入通孔14做准备。
进一步地,在一些实施方式中,第一升降驱动机构240驱动控制壳体固定机构210以及极耳部引导机构220相对于承载机构300沿预设装配方向下降,以带动壳体10沿着预设装配方向向承载机构300的方向移动。
而后,在壳体固定机构210相对于导向定位机构260下降至预设位置时,定位驱动机构265驱动至少两个导向板2631彼此拼合,以形成定位孔264。壳体10在进一步下降过程中,其开口端12抵接导向定位机构260中的至少两个导向板2631,至少两个导向板2631上的导向斜面2636对壳体10组价进行定位导向,以使得壳体10的开口端12抵接于承台面2635以对准定位孔264,并在定位孔264面对壳体10的一侧包围定位孔264。
而后,在一些实施方式中,定位驱动机构265驱动导向定位机构260与壳体固定机构210与壳体10一起沿着预设装配方向下降,以靠近电极组件20。同样的,在下降过程中,定位导向板263背对壳体10机构一侧的导向斜面2636对电极组件20进行定位导向,以使得电极组件20能够从定位孔264背对壳体固定机构210的另一侧中穿设于定位孔264内,并进一步通过开口端12,穿入容纳腔11内,从而实现电极组件20的精准入壳。
S300:在壳体套入电极组件的过程中,引导极耳部从通孔穿出容纳腔。
在一些实施方式中,在壳体10套入电极组件20的过程中,接触极耳部21,并引导极耳部21从通孔14穿出容纳腔11。可选地,此步骤可以包括以下步骤S311-S312:
S311:在第一阶段,在容纳腔内接触极耳部。
可选地,在壳体10套入电极组件20的过程中,在极耳部引导机构220相对运动到接触极耳部21的位置时,壳体固定机构210与极耳部引导机构220停止下降,极耳部引导机构220运动接触夹持住极耳部21。
在一些实施方式中,在极耳部引导机构220运动接触夹持住极耳部21之后,定位驱动机构265驱动至少两个导向板2631在预设装配方向的垂直方向上彼此分离,以远离壳体10,以使得撤离承台面2635对开口端12的止挡,使得壳体固定机构210能够将壳体10进一步套入电极组件20。
可选地,在极耳部引导机构220运动接触夹持住极耳部21之后,夹具驱动机构330可以驱动承载夹具320切换成卸载状态,以使得承载夹具320远离电极组件20以及底盖30,避让壳体10驱动固定机构以及壳体10,使得后续壳体10能够完全套入电极组件20,其开口端12能够顺利抵住底盖30。
S312:在第二阶段,控制壳体相对于极耳部下降,使得极耳部引导机构引导极耳部从通孔穿出容纳腔。
可选地,第一升降驱动机构240驱动第一支撑架211带动壳体固定机构210相对于极耳部引导机构220和极耳部21沿预设装配方向下降,使得壳体10能够相对于极耳部引导机构220和极耳部21下降沿预设装配方向下降,从而使得极耳部引导机构220引导极耳部21从通孔14穿出容纳腔11,壳体10顺利套入电极组件20,其开口端12能够顺利抵住底盖30,以完成电极组件20的入壳流程。
通过上述设置,在极耳部引导机构220能够在容纳腔11内接触极耳部21之后,壳体固定机构210进一步相对于极耳部引导机构220沿预设装配方向下降,使得极耳部引导机构220能够在第二阶段相对于极耳部21静止,此时壳体固定机构210再进一步带动壳体10沿预设装配方向下降时,极耳部引导机构220能够引导极耳部21从通孔14穿出容纳腔11,从而使得极耳部21在第二阶段不易接触到壳体10而阻挡壳体10套入电极组件20或者使得极耳部21弯折变形等情况发生,能够提高电极组件20入壳的效率,从而提高电池1的良品率。
在一些实施例中,装配方法还包括步骤S400:
S400:焊接极耳部和极柱。
可选地,在成功将壳体10套入电极组件20外部之后,极耳部21从通孔穿出容纳腔11,并在通孔14中与极柱15相对,此时焊接极耳部21与极柱15,以使得极耳部21与极柱15实现导电连接,能够与电极组件20一齐形成电流回路,使得电极组件20可以通过极柱15和极耳部21与外界连接,并实现充放电功能。
且将电极组件20的极耳部21和壳体10上的极柱15进行焊接,还能够保证极耳部21与极柱15之间连接的可靠性和稳定性。
在一些实施例中,如图1所示,电池1还可以包括极柱盖板40。装配方法还包括步骤S500:
S500:焊接极柱盖板与极柱,以使极柱盖板封闭通孔。
可选地,在极耳部21与极柱15焊接之后,可以在极柱15远离壳体10的一侧设置极柱盖板40,并且焊接极柱盖板40与极柱15,以使得极柱盖板40能够封闭通孔14,并且与壳体10一起将容纳腔11围合形成一个密闭的空间。如此设置使得外界的杂质水滴等物质不易通过通孔14进入电池的容纳腔11内,也使得容纳腔11的物质元件不易通过通孔14泄漏出外界。
而且焊接极柱盖板40与极柱15的设置,可以使得极柱盖板40通过极柱15与极耳部21连接,从而使得以使得电极组件20的能量可以通过面积较大的极柱15和极柱盖板40传输至电池1外,以提高电池1的充电和放电效率。

电池1还可以包括极柱盖板40。装配方法还包括:焊接极柱盖板40与极柱15,以使极柱盖板40封闭通孔14。
综上所述,本申请在入壳装置2上设置壳体固定机构210和极耳部引导机构220,其中壳体固定机构210在下降的过程中能够将壳体10通过开口端12套入电极组件20,而在壳体10套入电极组件20的过程中,极耳部引导机构220能够引导极耳部21从通孔14穿出容纳腔11。这样的设计使得电池1的电极组件20在入壳时,电池1的极耳部21能够被引导穿过通孔14,从而使得极耳部21不易阻挡壳体10套入电极组件20,以实现电极组件20的精准入壳,从而提高入壳装置2的装配效率以及良品率。
以上所述仅为本申请的实施例,并非因此限制本申请的专利范围,凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本申请的专利保护范围内。
