目前，从市场形势的发展来看，动力电池的应用越加广泛。动力电池不仅被应用于水力、火力、风力和太阳能电站等储能电源系统，而且还被广泛应用于电动自行车、电动摩托车、电动汽车等电动交通工具，以及航空航天等多个领域。随着动力电池应用领域的不断扩大，其市场的需求量也在不断地扩增。
动力电池的制备过程中，通常会经过电芯加工处理，也即是采用电芯加工设备对两块裸电芯进行合芯操作。
合芯操作即：将两个或更多电芯组件连接起来再合拢的操作方式。电芯组件之间可以通过焊接的形式，比如超声焊接、激光焊接等方式，将两个或更多电芯组件的极耳连接到端盖，然后依靠专用的电芯加工设备，对电芯组件、端盖进行定位，逐步旋转电芯组件，使得极耳能够弯折并贴合在电芯组件的端面上，从而让两块电芯组件能够贴合，方便后续工序进行装配。
本申请发明人注意到，每一个电芯组件上的极耳是由多层金属箔构成，在合芯操作过程中，随着电芯加工设备带动两块裸电芯进行转动，电芯组件与转动轴线之间的距离会发生变化，进而导致裸电芯与相对于端盖的距离发生变化，而未经过整形的极耳，在距离变化时其多层金属箔分别形成的弯折线会出现差异，由此，会使得极耳与端盖上的连接部分受到撕扯，进而导致出现极耳撕裂等不良情况。
为了缓解极耳在合芯过程中受到撕裂的问题，申请人研究发现，可以通过设置一个整形件，在合芯操作过程中可以对极耳进行整形，避免多层金属箔分别形成的弯折线出现差异，形成统一的弯折线，使得极耳不会因弯折受到撕扯，进而防止出现极耳撕裂等不良情况。除此以外，可以让加工设备上的支撑组件活动设置于固定架，，使得在合芯过程中能够及时调整极耳到端盖的距离；进而避免出现距离变化过大导致的极耳撕裂情况。
本申请实施例公开的电芯加工设备能够对动力电池进行合芯操作。动力电池可以但不限于二次电池或一次电池；在其他一些实施例中，动力电池还可以是锂硫电池、钠离子电池或镁离子电池，本申请不做限制。
需要说明的是，本申请实施例中公开的动力电池通常包括两块相互连接的电芯组件，本申请实施例的电芯加工设备能够针对该两块电芯组件进行合芯操作；在其他一些实施例中，动力电池可包括三块甚至更多块相互连接的电芯组件，相应的，本申请实施例的电芯加工设备能够针对该三块甚至更多块电芯组件进行合芯操作。
本处以动力电池通常包括两块相互连接的电芯组件为例进行说明。
参阅图1，图1为动力电池在进行合芯操作前的状态图；动力电池包括第一子电芯910、第二子电芯920、端盖930、壳体(未标出)以及其他的功能性部件(未标出)。
端盖930是指盖合于壳体的开口处以将动力电池的内部环境隔绝于外部环境的部件。不限地，端盖930的形状可以与壳体的形状相适应以配合壳体。在一些实施例中，端盖930可以由具有一定硬度和强度的材质(如铝合金)制成，这样，端盖930在受挤压碰撞时就不易发生形变，使动力电池能够具备更高的结构强度，安全性能也可以有所提高。端盖930上可以设置有如极柱931等的功能性部件。极柱931可以用于与第一子电芯910、第二子电芯920电连接，以用于输出或输入动力电池的电能。
在一些实施例中，端盖930上还可以设置有用于在动力电池的内部压力或温度达到阈值时泄放内部压力的泄压机构(未标出)，例如泄压阀。端盖930的材质也可以是多种的，比如，铜、铁、铝、不锈钢、铝合金、塑胶等，本申请实施例对此不作特殊限制。在一些实施例中，在端盖930的内侧还可以设置有绝缘件932，绝缘件932可以用于隔离壳体内的电连接部件与端盖930，以降低短路的风险。示例性的，绝缘件932可以是塑料、橡胶等。
壳体是用于配合端盖930以形成动力电池的内部环境的组件，其中，形成的内部环境可以用于容纳第一子电芯910、第二子电芯920、电解液以及其他部件。壳体和端盖930可以 是独立的部件，可以于壳体上设置开口，并在开口处使端盖930盖合开口以形成动力电池的内部环境。壳体可以是多种形状和多种尺寸的，例如长方体形、圆柱体形、六棱柱形等。壳体的形状可以根据第一子电芯910、第二子电芯920的具体形状和尺寸大小来确定。壳体的材质可以是多种，比如，铜、铁、铝、不锈钢、铝合金、塑胶等，本申请实施例对此不作特殊限制。
第一子电芯910、第二子电芯920的结构通常一致，第一子电芯910以及第二子电芯920是动力电池中发生电化学反应的部件；对应到本申请实施例中，第一子电芯910以及第二子电芯920为电芯组件，电芯组件通常由正极片和负极片卷绕或层叠放置形成，并且通常在正极片与负极片之间设有隔膜。正极片和负极片具有活性物质的部分构成电芯组件的主体部，正极片和负极片不具有活性物质的部分各自构成极耳，对应到本申请实施例中，也即是第一子电芯910的第一极耳912以及第二子电芯920的第二极耳922。每一个电芯组件通常具有两组极耳，在动力电池的充放电过程中，正极活性物质和负极活性物质与电解液发生反应，两组极耳作为输出电能的正极以及负极，并分别与两个极柱931连接，其中连接了正极极耳的极柱931作为动力电池的正极，连接了负极极耳的极柱931作为动力电池的负极以形成电流回路。正极极耳和负极极耳通常共同位于电芯本体的端面上，或是分别位于主体部的两端。
根据与本申请的一些实施例，参阅图1所示，端盖930设置在第一子电芯910、第二子电芯920之间，并将两块电芯电性连接。第一子电芯910的第一极耳912、第二子电芯920的第二极耳922位于端盖930的上方，第一极耳912、第二极耳922可通过连接片940转接到端盖930上的极柱931。
第一子电芯910、第二子电芯920的结构类似，均大致呈矩形块状。
第一子电芯910的第一电芯本体911上具有位于两端的第一端面9111、第二端面9112，以及连接在两个端面之间的第一侧面9113、第二侧面9114、第三侧面(未标出)以及第四侧面(未标出)。第一端面9111与第二端面9112相对设置；第一侧面9113、第三侧面为具有较大面积的大侧面且两者相对设置；第二侧面9114、第四侧面为具有较小面积的小侧面且两者相对设置；第一侧面9113和第二侧面9114相邻设置并位于第一端面9111与第二端面9112之间。第一极耳912设置于第一端面9111。
类似的，第二子电芯920的第二电芯本体921上具有位于两端的第一端面9211、第二端面9212，以及连接在两个端面之间的第一侧面9213、第二侧面9214、第三侧面(未标出)以及第四侧面(未标出)。第一端面9211与第二端面9212相对设置；第一侧面9213、第三侧面为具有较大面积的大侧面且两者相对设置；第二侧面9214、第四侧面为具有较小面积的侧面且两者相对设置；第一侧面9213和第二侧面9214相邻设置并位于第一端面9211与第二端面9212之间。第二极耳922设置于第一端面9211。
第一电芯本体911的第一端面9111与第二电芯本体921的第一端面9211相邻设置，并且分别位于端盖930的两侧；由第一电芯本体911的第一端面9111引出的第一极耳912与端盖930一侧连接，由第二子电芯920的第一端面9211引出的第二极耳922与端盖930的另一侧连接。
参阅图2，图2为动力电池进行合芯操作后的状态图，电芯加工设备对动力电池的第一子电芯910、第二子电芯920进行合芯操作后，第一电芯本体911的第一端面9111与第二电芯本体921的第一端面9211分别贴合在端盖930上，同时第一电芯本体911的较大面积的第一侧面9113、第二电芯本体921的较大面积的第一侧面9213将贴合，从而方便后续的装配工序进行。
根据本申请的一些实施例，参照图3至图7所示，其中，图3和图4中的电芯加工设备处于起始状态，第一支撑组件处于第一起始角度，第二支撑组件处于第二起始角度；图5中的电芯加工设备处于中间状态，第一支撑组件处于第一预设角度，第二支撑组件处于第二预设角度；图6和图7中的电芯加工设备处于合拢状态，第一支撑组件处于第一合芯角度，第二支撑组件处于第二合芯角度。
本申请的第一方面提供了一种电芯加工设备，其包括：第一支撑组件100、第二支撑组件200、第三支撑组件300。
其中，第一支撑组件100用于固定电芯本体；为了便于描述，本申请中定义第一支撑组件100固定第一子电芯910的第一电芯本体911。第一支撑组件100能够绕第一转动轴线100a转动。
第二支撑组件200用于固定电芯本体；为了便于描述，本申请中定义第二支撑组件200固定第二子电芯920的第二电芯本体921。第二支撑组件200能够绕第二转动轴线200a转动。
第三支撑组件300，用于固定极耳以及端盖930。为了便于描述，本申请中定义第三支撑组件300固定第一极耳912、第二极耳922以及端盖930。
参阅图8至图11所示，第三支撑组件300包括支撑座310以及整形件320。
整形件320相对于支撑座310活动设置，以在整形件320与支撑座310之间形成固定空间330。其中，在需要时，整形件320可动作至支撑座310沿第二方向的上方，如此，整形件320与支撑座310之间即可以沿第二方向从上下分别对第一极耳912、第二极耳922以及端盖930实施限位，形成用于固定极耳以及端盖930的固定空间330；整形件320通常为具有一定厚度的压板结构或者压杆，由具有一定硬度和强度的材质制成，例如铝合金、不锈钢、碳钢等，这样整形件320能够提供足够足够的强度压接在极耳上提供限位。整形件320沿第二方向向下抵压在第一极耳912、第二极耳922上，支撑座310沿第二方向支撑在端板930的下方，从而避免在合芯的过程中，第一极耳912、第二极耳922相对于端盖930出现异 动。
在一些实施例中，参阅图1至图11所示，电芯加工设备包括固定架400。
固定架400通常为具有一定厚度的板体，并与外界例如地面通过支脚固定连接，固定架400用于固定电芯加工设备的其他部件。
第一支撑组件100以及第二支撑组件200沿第一方向活动设置在固定架400上，且第一支撑组件100与第二支撑组件200分别布置在第三支撑组件300沿第一方向的两侧。也即是说，第一支撑组件100能够带动第一电芯本体911沿第一方向靠近或者远离第三支撑组件300，第二支撑组件200能够带动第二电芯本体921沿第一方向靠近或者远离第三支撑组件300。
第三支撑组件300沿第二方向活动设置于固定架400；也即是说，第三支撑组件300能够带动第一极耳912、第二极耳922以及端盖930，沿第一方向向上或者向下运动以调整端盖930与第一电芯本体911、第二电芯本体921的距离不至于过远。
第一转动轴线100a与第二转动轴线200a平行设置。第二方向与第一方向垂直设置。参阅图3所示，图中X所示为第一方向，其为水平沿前后延伸；图中Z所示为第二方向，其为竖直沿上下延伸；第一转动轴线100a与第二转动轴线200a均垂直于第一方向以及第二方向，并沿图3中Y所示的第三方向延伸。
合芯的过程具体是：第一支撑组件100能够带动固定其上的第一电芯本体911绕第一转动轴线100a转动，以使得第一子电芯910的第一极耳912弯折；第二支撑组件200能够带动第二电芯本体921绕第二转动轴线200a转动，以使得第二子电芯920的第二极耳922弯折；第一支撑组件100与第二支撑组件200的转动通常等速相反，结合图5所示方位，即其中第一支撑组件100沿逆时针方向旋转，第二支撑组件200沿顺时针方向旋转，使得第一电芯本体911的较大面积的第一侧面9113、第二电芯本体921的较大面积的第一侧面9213能够相互靠拢贴合。与此同时，第一支撑组件100沿第一方向相对于第三支撑组件300靠近或者远离，以调整第一支撑组件100与第三支撑组件300沿第一方向上的距离；第二支撑组件200沿第一方向相对于第三支撑组件300靠近或者远离，以调整第二支撑组件200与第三支撑组件300沿第一方向上的距离；第三支撑组件300沿第二方向活动设置，以调整第三支撑组件300与第二支撑组件200、第一支撑组件100在沿第二方向上的距离；从而方便后续的装配工序进行。
在本申请各个实施例中，定义第一极耳912弯折的痕迹所形成的折线为第一弯折线，定义第二极耳922弯折痕迹所形成为第二弯折线。可以理解的是，如果合芯的过程中，第一弯折线与第一转动轴线100a共线，第二弯折线与第二转动轴线200a共线，则在合芯过程中，第一极耳912、第二极耳922的根部只会受到弯折的力度而不会受到外力拉扯；但实际合芯的过程中，第一弯折线通常与第一转动轴线100a平行，第二弯折线与第二转动轴线200a平 行，两者之间存在一定的间距，且这个间距随着第一支撑组件100以及第二支撑组件200的转动会发生变化，这个变化不仅是沿第一方向的距离变化，还有沿第二方向上的距离变化。
由此，通过第一支撑组件100以及第二支撑组件200沿第一方向活动设置，并通过第三支撑组件300沿第二方向活动设置，使得在合芯过程中，电芯加工设备能够分别从第一方向上以及第二方向上进行距离补偿，使得第一弯折线与第一转动轴线100a之间的距离、第二弯折线与第二转动轴线200a之间的距离保持不变，进而，可以有效地防止第一极耳912、第二极耳922出现撕裂情况。
支撑座310上形成有极柱定位槽311。极柱定位槽311形状应当与端盖930上的极柱931相适配，例如为圆形或者方形；支撑座310整体呈T字形，且靠近端盖930的上部通常沿第三方向延伸；支撑座310可以由具有一定硬度和强度的材质制成，例如铝合金、不锈钢、碳钢等，这样支撑座310能够提供足够支撑第一子电芯910、第二子电芯920、端盖930的强度，且不易发生形变，使电芯加工设备能够具备更高的结构强度，确保合芯操作的进行。
可选的，极柱定位槽311数量为两个，且沿第三方向排布，极柱定位槽311通过与极柱931嵌入配合实现定位，进而实现支撑座310从底部对端盖930进行限位。
在一些实施例中，当第一支撑组件100绕第一转动轴线转动至第一支撑组件100与固定架400夹设为第一预设角度，第二支撑组件200绕第二转动轴线转动至第二支撑组件200与固定架400夹设为第二预设角度时，整形件320远离支撑座310。
第一支撑组件100绕第一转动轴线100a转动的过程中，第一支撑组件100相对于固定架400依次具有第一起始角度、第一预设角度以及第一合芯角度；第二支撑组件200绕第二转动轴线200a转动的过程中，第二支撑组件200相对于固定架400依次具有第二起始角度、第二预设角度以及第二合芯角度。
电芯加工设备具有起始状态、中间状态以及合拢状态。
其中，参阅图1和图3所示，电芯加工设备处于起始状态，第一支撑组件100相对于固定架400处于第一起始角度；第二支撑组件200相对于固定架400处于第二起始角度。
第一支撑组件100相对于固定架400处于第一起始角度，第一子电芯910安置于第一支撑组件100上，第一固定板130(下文提及)的板面与第二方向垂直，且与第一方向平行；如此，可以使得第一电芯本体911的第一侧面9113平行于第一方向，且垂直于第二方向；类似的，第二支撑组件200相对于固定架400处于第二起始角度，第二子电芯920安置于第二支撑组件200上，可以使得第二电芯本体921的第一侧面9213平行于第一方向，且垂直于第二方向；通常，为了便于安置，应能够将第一电芯本体911的第一侧面9113与第二电芯本体921的第一侧面9213设置于同一个水平面中。
可选的，第一起始角度可为0°，也即是第一支撑组件100的底部的第一固定板130(下文提及)与固定架400的角度为0°，第一固定板130与固定架400两者为平行设置。 第二起始角度可为0°，也即是第二支撑组件200底部的第二固定板230(下文提及)与固定架400的角度为0°，第二固定板230与固定架400平行设置。
参阅图5所示，电芯加工设备处于中间状态，第一支撑组件100相对于固定架400处于第一预设角度，第二支撑组件200相对于固定架400处于第二预设角度。
第一支撑组件100相对于固定架400处于第一预设角度，第一子电芯910安置于第一支撑组件100上，第一固定板130的板面与第一方向呈角度设置，且与第二方向呈角度设置；如此，可以使得第一电芯本体911的第一侧面9113与第一方向呈角度设置，且与第二方向呈角度设置；类似的，第二支撑组件200相对于固定架400处于第二预设角度，第二子电芯920安置于第二支撑组件200上，第二固定板130的板面与第一方向呈角度设置，且与第二方向呈角度设置；如此，可以使得第二电芯本体921的第一侧面9213与第一方向呈角度设置，且与第二方向呈角度设置。
从起始状态向中间状态切换的过程中，第一电芯本体911的第一侧面9113与第二电芯本体921的第一侧面9213是相向的转动，以最终能够转动到合拢状态。
这一个过程中，整形件320可位于支撑座310的上方；与支撑座310之间形成用于固定极耳以及端盖930的固定空间330；从而避免第一极耳912、第二极耳922相对于端盖930出现异动。
第一预设角度与第二预设角度的大小可以根据实际需要人工设定，但不宜设置的过大或者过小，让第一极耳912、第二极耳922沿着整形件320的边缘稳定的形成折线即可。角度数值过大，会导致整形件320与第一支撑组件100、第二支撑组件200发生干涉，角度数值过小，会导致第一极耳912、第二极耳922还未形成稳定的折线，整形件320就松开，进而导致第一极耳912、第二极耳922相对于端盖930出现异动。
本申请实施例中，第一预设角度可为30°，也即是，第一支撑组件100的底部相对于固定架400，从第一起始角度绕第一转动轴线100a沿逆时针方向转动30°。第二预设角度可为30°，也即是，第二支撑组件200的底部相对于固定架400，从第二起始角度绕第二转动轴线200a沿顺时针方向转动30°。
可选的，第一预设角度可定义为第一固定板130与固定架400夹角为15°～45°中的任意值；第二预设角度可定义为第二固定板230与固定架400的夹角为15°～45°中的任意值。第一预设角度与第二预设角度通常在数值上相等。
参阅图2和图6所示，电芯加工设备处于合拢状态，第一支撑组件100相对于固定架400处于第一合芯角度，第二支撑组件200相对于固定架400处于第二合芯角度。
第一支撑组件100相对于固定架400处于第一合芯角度，第一子电芯910安置于第一支撑组件100上，第一固定板130的板面与第二方向平行，且与第一方向垂直；如此，可以使得第一电芯本体911的第一侧面9113与第一方向垂直，且与第二方向平行；类似的，第二 支撑组件200相对于固定架400处于第二合芯角度，第二子电芯920安置于第二支撑组件200上，可以使得第二电芯本体921的第一侧面9213与第一方向垂直，且与第二方向平行。如此，第一支撑组件100上的第一固定板130(下文提及)的板面和第二支撑组件200的第二固定板230(下文提及)的板面在第一方向上相对设置，以能够使得第一电芯本体911的较大面积的第一侧面9113、第二电芯本体921的较大面积的第一侧面9213贴合。
其中，第一合芯角度可为90°，也即是，第一支撑组件100的底部相对于固定架400，从第一起始角度绕第一转动轴线100a沿逆时针方向转动90°，相当于从第一预设角度绕第一转动轴线100a沿逆时针方向再转动60°。第二合芯角度可为90°，也即是，第二支撑组件200的底部相对于固定架400，从第二起始角度绕第二转动轴线200a沿顺时针方向转动90°，相当于从第二预设角度绕第二转动轴线200a沿顺时针方向再转动60°。
本处第一支撑组件100的底部可以是第一固定板130(下文提及)；第二支撑组件200的底部可以是第二固定板230(下文提及)。
在一些实施例中，参阅图3至图5所示，电芯加工设备从起始状态向中间状态切换。
第一支撑组件100绕第一转动轴线100a从第一起始角度向第一预设角度转动，且第二支撑组件200绕第二转动轴线200a从第二起始角度向第二预设角度转动。
在此过程中，整形件320与支撑座310沿第二方向相对设置，整形件320与支撑座310之间形成用于固定极耳以及端盖930的固定空间330；从而避免在合芯的过程中，第一极耳912、第二极耳922相对于端盖930出现异动。
此外，电芯加工设备在起始状态下，第一极耳912、第二极耳922尚未完全弯折形成稳定的第一弯折线以及第二弯折线，由整形件320压接在第一极耳912、第二极耳922上，可以对第一极耳912、第二极耳922提供整形，第一极耳912、第二极耳922沿着整形件320的边缘稳定的形成折线，使得第一弯折线、第二弯折线的一致性好，进而能够防止合芯的质量不稳定，利于自动化生产效率，提高生产效率。
在一些实施例中，参阅图5至图7所示，电芯加工设备从起始状态向中间状态切换。
第一支撑组件100绕第一转动轴线100a从第一预设角度向第一合芯角度转动，且第二支撑组件200绕第二转动轴线200a从第二预设角度向第二合芯角度转动；整形件320与支撑座310远离。第一极耳912、第二极耳922沿着整形件320的边缘稳定的形成折线后，整形件320移动至支撑座310沿第三方向的两端；从而防止整形件320对逐渐靠拢的第一电芯本体911以及第二电芯本体921形成干涉，防止极耳撕裂。在整形件320移走以后，依靠支撑座310上的极柱定位槽311以及其他附属结构对端盖930实施定位。

连接板340作为固定件，用于固定支撑座310、整形件320以及驱动单元350；当连接板340沿第二方向活动，即可以带动支撑座310、整形件320沿第二方向整体运动；且整形件320能够相对于连接板340进行动作。
支撑座310相对于固定架400沿第二方向活动，进而可以带动支撑座310以及整形件320整体沿第二方向移动，这个过程中，支撑座310以及整形件320的相对位置不变；驱动单元350可驱动整形件320相对于连接板340移动，以在整形件320与支撑座310之间形成固定空间330，从而在电芯加工设备从起始状态向中间状态切换的过程中，固定第一极耳912、第二极耳922，防止其相对于端盖930出现非正常的移动，进而可以避免极耳撕裂情况。
在一些实施例中，参阅图8至图11所示，第三支撑组件300包括两个整形件320以及两组驱动单元350，支撑座310沿第三方向延伸为长条形；两个整形件320沿第三方向分别位于支撑座310的两端；每一组驱动单元350包括水平驱动件351以及竖直驱动件352；竖直驱动件352与整形件320传动连接以驱动整形件320沿第二方向往复移动；水平驱动件351能够驱动整形件320沿第三方向往复移动。第三方向、第二方向与第一方向彼此垂直设置。

如此，通过竖直驱动件352驱动整形件320相对于连接板340沿第二方向往复移动；通过水平驱动件351驱动整形件320相对于连接板340沿第三方向往复移动；当第一电芯本体911固定在第一支撑组件100上，第二电芯本体921固定在第二支撑组件200上，整形件320先沿第二方向上升一定高度，然后沿第三方向移动至支撑座310上方，然后整形件320沿第二方向下降一定高度以压接在第一极耳912、第二极耳922上；在电芯加工设备从起始状态向中间状态切换的过程中，整形件320配合底部的支撑座310，共同从上下固定第一极耳912、第二极耳922以及端盖930，防止出现相对位移，并且，整形件320压接在第一极耳912、第二极耳922上，可以对第一极耳912、第二极耳922提供整形，第一极耳912、第二极耳922沿着整形件320的边缘稳定的形成折线，使得第一弯折线、第二弯折线的一致性好。

在一些实施例中，第三驱动机构530为气缸装置。其他一些实施例中，为了便于精确的调节第三支撑组件300沿第二方向到第二支撑组件200、第一支撑组件100的距离，第三驱动机构530可以是伺服电机，移动精度更高，反应速度更快。
在一些实施例中，支撑部531可以由具有一定硬度和强度的材质制成，例如铝合金、不锈钢、碳钢等；这样支撑部531能够提供足够的强度支撑第三驱动机构530、第三导轨532以及滑动块533。支撑部531上还可以增设加强肋板534，以提高其结构强度。
在一些实施例中，参阅图3至图7，以及图10所示，第一支撑组件100包括第一转动器110、第一固定座120以及第一固定板130。

在一些实施例中，第一转动器110可以是电机。
在一些实施例中，参阅图3至图7，以及图12所示，电芯加工设备包括第一驱动机构510，第一驱动机构510与第一固定座120传动连接，以驱动第一固定座120沿第一方向 活动。
第一驱动机构510为伺服电机，其输出轴连接有第一丝杆111，两个第一固定座120之间连接有第一固定杆170；通过在第一固定杆170上开设螺孔，第一丝杆111螺旋在其中，当伺服电机带动第一丝杆111转动，螺纹将转动转化为第一固定杆170相对于第一丝杆111沿第一方向的运动，进而带动第一固定座120在第一导轨160的导向下，沿第一方向相对于固定架400往复移动。
在一些实施例中，参阅图3至图7，以及图13所示，第二支撑组件200包括第二转动器210、第二固定座220以及第二固定板230。

在一些实施例中，第二转动器210可以是电机。
在一些实施例中，参阅图3至图7，以及图13所示，电芯加工设备包括第二驱动机构520，第二驱动机构520与第二固定座220传动连接，以驱动第二固定座220沿第一方向活动。
第二驱动机构520为伺服电机；其具体的传动结构可以与第一驱动机构510类似。第二驱动机构520的输出轴连接有第二丝杆，两个第二固定座220之间连接有第二固定杆；通过在第二固定杆上开设螺孔，第二丝杆螺旋在其中，当伺服电机带动第二丝杆转动，螺纹将转动转化为第二固定杆相对于第二丝杆沿第一方向的运动，进而带动第二固定座220在第二导轨260的导向下，沿第一方向相对于固定架400往复移动。
在一些实施例中，电芯加工设备处于起始状态下，参阅图1、图3、图12以及图13所示，第一固定板130的板面用于放置平躺的第一电芯本体911。第一支撑组件100处于第一起始角度，第一固定板130的板面与第二方向垂直，且与第一方向平行。第二固定板230的板面用于放置平躺的第二电芯本体912。第二支撑组件200处于第一起始角度，第二固定板230的板面与第二方向垂直，且与第一方向平行。
在一些实施例中，电芯加工设备处于中间状态下，参阅图5、图12以及图13所示，第一支撑组件100处于第一预设角度；第一固定板130的板面与第一方向呈角度设置，且与第二方向呈角度设置。第二支撑组件200处于第一预设角度；第二固定板230的板面与第一方向呈角度设置，且与第二方向呈角度设置。
从起始角度到达第一预设角度之前，整形件320压接在第一极耳912、第二极耳922上，以方便第一极耳912、第二极耳922沿着整形件320的边缘弯折形成第一弯折线。
通常第一固定板130的板面与第一方向夹角不宜过大，可以取角度为15°～45°中的任意值。角度太小了，第一极耳912、第二极耳922尚来不及形成稳定的第一弯折线、第二弯折线，整形件320即已撤走，导致第一极耳912、第二极耳922可能相对于端盖930移动，进而导致撕裂；角度太大，整形件320撤走的时候容易与其他结构发生干涉。
在一些实施例中，电芯加工设备处于合拢状态下，参阅图2、图6以及图12所示，
第一支撑组件100处于第一合芯角度，第一固定板130的板面与第二方向平行，且与第一方向垂直。第二支撑组件200处于第一合芯角度，第二固定板230的板面与第二方向平行，且与第一方向垂直。也即是说第一支撑组件100从起始状态经过中间状态到达合拢状态，第一固定板130的板面始终与第一转动轴线100a平行，第二支撑组件200从起始状态经过中间状态到达合拢状态，第二固定板230的板面始终与第二转动轴线200a平行而不会出现交叉情况。
本申请的第二方面提供一种电芯加工方法，使用上述的电芯加工设备进行合芯操作；参阅图14所示，电芯加工方法包括：
S10、将电芯本体分别固定在第一支撑组件100以及第二支撑组件200上。
S20、将第一支撑组件100绕第一转动轴线100a转动至第一合芯角度，同时将第二支撑组件200绕第二转动轴线200a转动至第二合芯角度；第一支撑组件100以及第二支撑组件200沿第一方向相向靠拢，第三支撑组件300沿第二方向靠近第一支撑组件100以及第二支 撑组件200。
通过第一支撑组件100以及第二支撑组件200沿第一方向活动设置，并通过第三支撑组件300沿第二方向活动设置，使得在合芯过程中，电芯加工设备能够分别从第一方向上以及第二方向上进行距离补偿，使得第一弯折线与第一转动轴线100a之间的距离、第二弯折线与第二转动轴线200a之间的距离保持不变，进而，可以有效地防止第一极耳912、第二极耳922出现撕裂情况。
在一些实施例中，S20步骤包括：
S21、当第一支撑组件100从第一起始角度向第一预设角度转动，且第二支撑组件200从第二起始角度向第二预设角度转动时；第一支撑组件100以及第二支撑组件200沿第一方向与第三支撑组件300保持固定。
也即是说，电芯加工设备从起始状态切换到中间状态的过程中，第一支撑组件100以及第二支撑组件200与第三支撑组件300保持固定，此时主要通过整形件320沿第二方向向下抵压在第一极耳912、第二极耳922上，避免第一极耳912、第二极耳922相对于端盖930出现异动，并可以对第一极耳912、第二极耳922提供整形，第一极耳912、第二极耳922沿着整形件320的边缘稳定的形成折线，使得第一弯折线、第二弯折线的一致性好。
S22、整形件320远离支撑座310。如此，可避免整形件320与第一支撑组件100、第二支撑组件200形成干涉。
S23、当第一支撑组件100从第一预设角度向第一合芯角度转动，且第二支撑组件200从第二预设角度向第二合芯角度转动时；第一支撑组件100以及第二支撑组件200沿第一方向分别向第三支撑组件300靠拢，第三支撑组件300沿第二方向靠近第一支撑组件100以及第二支撑组件200。
通过第一支撑组件100以及第二支撑组件200沿第一方向活动设置，并通过第三支撑组件300沿第二方向活动设置，使得在合芯过程中，电芯加工设备能够分别从第一方向上以及第二方向上进行距离补偿，使得第一弯折线与第一转动轴线100a之间的距离、第二弯折线与第二转动轴线200a之间的距离保持不变，进而，可以有效地防止第一极耳912、第二极耳922出现撕裂情况。
本申请的第三方面提供一种电池生产线。该电池生产线包括上述的电芯加工设备。
最后应说明的是：以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
