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，以及军事装备和航空航天等多个领域。
本发明人注意到，在动力电池的生产过程中，动力电池的电芯模组通常由多个电芯堆叠而成，随着对电芯模组的成组效率要求的提高，电芯模组的长度不断加长。现有技术中，通过在托盘上将多个电芯挤压堆叠成模组，并通过托盘对电芯模组进行转运。由于电芯在堆叠前需间隔码放，从而相应地增加了托盘的长度，进而增加了托盘的制造成本，且延长了生产线的长度。同时，由于电芯在挤压成模组的过程中，电芯的底面与托盘表面间相互摩擦，从而容易造成电芯底面的划伤。
为了解决由于托盘的长度过长，弹簧机构的伸缩量大，导致托盘的制造成本高的问题，本申请发明人研究发现，通过在其他部件上对多个电芯进行挤压并堆叠成电芯模组，再将电芯模组转移至托盘上，通过托盘对电芯模组进行输送，能 够有效地减少托盘的长度，减少托盘上弹簧机构的伸缩量，并降低托盘的制造成本，同时，还能够有效地减少因电芯的底面与托盘表面间相互摩擦，造成的电芯底面的划伤。
基于上述考虑，发明人经过深入研究，设计了一种电芯模组的堆叠装置，通过在堆叠装置中设置支撑机构，将电芯放置于支撑机构上，通过压紧机构沿支撑机构的轴向方向移动，将多个电芯挤压成电芯模组，并将电芯模组转移至托盘上，通过托盘将电芯模组输送至下一工序，电芯模组的挤压过程无需在脱盘上进行操作，从而减小了托盘的长度尺寸，降低了托盘的制造成本，同时缩短了生产线的长度，使堆叠装置的占地面积减小，进一步地便于其他设备的布置，同时由于托盘的长度尺寸减小，能够提高托盘的输送效率，进而提高了生产效率。
同时，由于无需在托盘上进行堆叠，仅需在将电芯模组转移至托盘上进行输送，能够有效地防止由于电芯模组在托盘上滑动而造成的刮伤。
本申请提供的电芯模组的堆叠装置和堆叠方法，可用于将多个电芯挤压堆叠成电芯模组。电芯模组可用于任何电池包或电池，或者一次电池和二次电池，例如，二次电池包括锂离子电池、钠离子电池、锂硫电池、镁离子电池等。这种电池适用于各种使用电池的用电设备，例如手机、便携式设备、笔记本电脑、电瓶车、电动玩具、电动工具、电动车辆、船舶和航天器等，例如，航天器包括飞机、火箭、航天飞机和宇宙飞船等；电池或电池包用于为上述用电设备提供电能。
第一方面，本申请提出了一种电芯模组的堆叠装置。结合图1至图6所示，图1是本申请一实施方式提供的堆叠装置1的结构示意图；图2是本申请一实施方式提供的电芯2码放于堆叠装置1上的初始位置结构示意图；图3是本申请一实施方式提供的电芯2码放于堆叠装置1上堆叠成电芯模组3后的结构示意图；图4是本申请一实施方式提供的堆叠装置1的另一角度结构示意图；图5是本申请一实施方式提供的电芯模组3转移至托盘40后的构示意图；图6是本申请一实施方式提供的堆叠装置1的A部放大结构示意图。在本申请的一些实施方式中，堆叠装置1包括机架10、支撑机构20和压紧机构30。支撑机构20用于支撑电芯2，压紧机构30与机架10相连，部分压紧机构30能够沿支撑机构20的轴向方向移动，并用于将多个电芯2挤压成电芯模组3，托盘40以可相对机架 10移动的方式设于机架10，并用于支撑电芯模组3。
具体地，堆叠装置1用于电芯模组3的生产过程中，可以将多个电芯2通过挤压的方式堆叠至一起，并形成电池模组3。机架10构成堆叠装置1的基本结构，用于支撑整个堆叠装置1，堆叠装置1的其他结构组成可分别设置于机架10上。支撑机构20用于支撑电芯2，使电芯2能够在支撑机构20上完成挤压。压紧机构30能够提供一定的压紧力并用于压紧多个电芯2，从而使多个电芯2在压紧机构30的压紧力的作用下堆叠在一起，并形成电芯模组3。支撑机构20的轴向方向即支撑机构20的延伸方向，即如图1所示的堆叠装置的长度方向。本申请中的电芯2也指电池单体，电芯模组3也指电池模组。电池单体是指组成电池模块或电池包的最小单元。电池模块可以包括多个电池单体，多个电池单体可以先串联或并联或混联组成电池模块，多个电池模块再串联或并联或混联组成电池。其中，在本申请的一些实施方式中，多个电芯2沿堆叠装置1的长度方向码放于支撑机构20上，堆叠后的电芯模组3中的任意相邻的两个电芯2间的大面相对设置。用于形成电芯模组3的单个电芯2的长度方向与堆叠装置1的长度方向相垂直，电芯2的宽度方向与堆叠装置1的长度方向相平行，电芯2的高度方向与堆叠装置1的高度方向相平行，且电芯2的长度方向的轮廓尺寸大于电芯2的宽度方向的轮廓尺寸。托盘40整体为盘状结构，用于承载电芯模组3，并能够相对机架10移动，从而将电芯模组3输送至下一工序。
本申请的技术方案中，通过设置支撑机构20，将电芯2放置于支撑机构20上，通过压紧机构30沿支撑机构20的轴向方向移动，将多个电芯2挤压成电芯模组3，并将电芯模组3转移至托盘40上，通过托盘40将电芯模组3输送至下一工序，电芯模组3的挤压过程无需在脱盘40上进行操作，从而减小了托盘40的长度尺寸，降低了托盘40的制造成本，同时缩短了生产线的长度，使堆叠装置1的占地面积减小，进一步地便于其他设备的布置。
同时，由于无需在托盘40上进行堆叠，仅需在将电芯模组3转移至托盘40上进行输送，能够有效地防止由于电芯模组3在托盘40上滑动而造成的刮伤。
在本申请的一些实施方式中，结合图1至图3所示，支撑机构20包括平行设置的第一支撑件21和第二支撑件22，第一支撑件21和第二支撑件22分别以 可滑动的方式与机架10相连，且滑动的方向与支撑机构20的轴向方向相垂直，以使第一支撑件21和第二支撑件22相对靠近或相对远离。
具体地，第一支撑件21和第二支撑件22分别用于在电芯2的两侧支撑电芯2，第一支撑件21和第二支撑件22共同形成支撑机构。且为保证第一支撑件21和第二支撑件22能够同时对多个电芯3支撑，第一支撑件21和第二支撑件22间平行设置。其中，与支撑机构20的轴向方向相垂直的方向即为堆叠装置1的宽度方向。
通过将第一支撑件21和第二支撑件22分别以可滑动的方式与机架10相连，当电芯2的长度尺寸较大时，可控制第一支撑件21和第二支撑件22相对远离，从而增大第一支撑件21和第二支撑件22的间距尺寸，用于对长度尺寸较大的电芯2进行支撑；当电芯2的长度尺寸较小时，可控制第一支撑件21和第二支撑件22相对靠近，从而减小第一支撑件21和第二支撑件22的间距尺寸，用于对长度尺寸较小的电芯2进行支撑，进而能够根据电芯2的长度尺寸调节第一支撑件21和第二支撑件22的间距尺寸，对不同长度尺寸的电芯2进行支撑。
在本申请的一些实施方式中，结合图1、图2和图7所示，图7是本申请一实施方式提供的堆叠装置1的B部放大结构示意图。堆叠装置1还包括伸缩机构，伸缩机构与机架10相连，第一支撑件21和第二支撑件22分别与伸缩机构相连，并在伸缩机构的作用下相对靠近或相对远离。
具体地，伸缩机构能够沿堆叠装置1的宽度方向往复运动，伸缩机构的驱动端分别与第一支撑件21和第二支撑件22相连，从而驱动第一支撑件21和第二支撑件22相对靠近或相对远离。
通过伸缩机构控制第一支撑件21和第二支撑件22相对靠近运动或相对远离运动，能够有效地提高堆叠装置1的自动化程度。
在本申请的一些实施方式中，再次结合图1、图2和图7所示，伸缩机构包括第一驱动件51和第二驱动件(图中未示出)，第一驱动件51与第一支撑件21驱动连接，第二支撑件22与第二驱动件驱动连接。
具体地，第一驱动件51的驱动端与第一支撑件21相连，用于驱动第一支撑件21靠近或远离第二支撑件22，第二驱动件的驱动端与第二支撑件22相连， 用于驱动第二支撑件22靠近或远离第一支撑件21。在本申请的一些实施方式中，第一驱动件51和第二驱动件分别设于机架10的长度方向的两端，从而有效地利用机架1上的空间。第一驱动件51和第二驱动件可以分别为驱动气缸。
通过第一驱动件51和第二驱动件分别对第一支撑件21和第二支撑件22进行控制，能够进一步地提高堆叠装置1的自动化程度，并能够对一些不对称结构的电芯2进行支撑，使不对称结构的电池的中心与机架10的中心相重合。
在本申请的一些实施方式中，还可以将伸缩机构仅设置成一个驱动件，驱动件的两侧分别设有驱动端，两侧的驱动端分别与第一支撑件21和第二支撑件22相连，从而通过一个驱动件驱动第一支撑件21和第二支撑件22同时运动，进而保证第一支撑件21和第二支撑件22运动的同步性。
在本申请的一些实施方式中，结合图1至图6所示，托盘40以可相对滑动的方式设于机架10，当第一支撑件21和第二支撑件22间隔设置且形成有第一开口23时，托盘40能够滑动至支撑机构20的下方并与第一开口23正对设置。
具体地，托盘40可在滑动过程中设于支撑机构20的下方，其中，可以在机架10上间隔设有多个转筒，托盘40放置于多个转筒上，随着转筒的转动，托盘能40够沿多个转筒的转动方向相对机架10滑动。当多个电芯2挤压堆叠成电芯模组3后，需要将电芯模组3转移至托盘40上。此时控制第一支撑件21和第二支撑件22相对远离，并在二者间形成第一开口23，并使第一开口23的开口尺寸大于电芯模组3的横截面尺寸，从而通过第一开口23将电芯模组3放置于与第一开口23正对设置的托盘40上，从而完成对电芯模组3的转移。
在本申请的一些实施方式中，为了便于托盘40的设置以及对电芯模组3的输送，托盘40能够沿堆叠装置1的长度方向滑动。
由于在电芯模组转3移至托盘40的过程中，仅需控制电芯模组3沿机架10的高度方向运动，无需对电芯模组3进行大规模的移动或转动，便于将电芯模组3转移至下方的托盘40上，从而通过托盘40将电芯模组3输送至下一工序。同时，可减少电芯模组3转移过程中的空间占用率，进一步地缩小堆叠装置1的空间占用率，便于布置其他设备。
在本申请的一些实施方式中，结合图1、图3、图8和图9所示，图8是本 申请一实施方式提供的堆叠装置1的C部放大结构示意图；图9是本申请一实施方式提供的托盘40的结构示意图。堆叠装置1还包括至少一个托盘锁紧机构60，托盘40上设有至少一个夹持组件43，托盘锁紧机构60可与夹持组件43相连，并用于驱动夹持组件43移动，以使夹持组件43夹紧或松开托盘40上的电芯模组3。
具体地，托盘上40设有夹持组件43，夹持组件43用于对转移至托盘40上的电芯模组3进行夹紧固定，防止电芯模组3在托盘40的输送过程中掉落。在托盘40的移动过程中，托盘40上的夹持组件43可与托盘锁紧单元60相连，从而通过托盘锁紧单元60驱动夹持组件43移动。在本申请的一个实施方式中，在机架10的长度方向的两端分别设有一个托盘锁紧单元60，相对应的，在托盘40的长度方向的两端还分别设有一个夹持组件43，从而通过两端的托盘锁紧单元60分别驱动夹持组件43运动，共同对托盘上40的电芯模组3进行夹紧固定。其中，在机架10的长度方向以及托盘40的长度方向分别与堆叠装置1的长度方向相同。
通过将托盘锁紧机构60与托盘40的夹持组件43相连，能够控制夹持组件43移动，从而对托盘40上的电芯模组3进行夹紧，使电芯模组3相对托盘40的位置固定，从而通过托盘40将电芯模组3输送至下一工序，避免电芯模组3在输送过程中发生掉落。
在本申请的一些实施方式中，结合图1、图2、图3、图8、图9和图10所示，图10是本申请一实施方式提供的托盘40的D部放大结构示意图。托盘锁紧机构60包括第三驱动件611、第四驱动件612和锁紧件63，锁紧件63可与夹持组件43相连，锁紧件63在第三驱动件611的驱动作用下沿竖直方向运动，锁紧件63在第四驱动件612的作用下带动夹持组件43共同沿堆叠装置1的长度方向移动。
具体地，第三驱动件611的驱动端与第四驱动件612相连，或通过连接件与第四驱动件612相连，并用于驱动第四驱动件612沿竖直方向运动，即沿堆叠装置1的高度方向运动。第四驱动件612的驱动端与锁紧件63相连，并用于驱动锁紧件63沿堆叠装置1的长度方向移动。锁紧件63用于连接固定夹持组件43， 从而带动夹持组件43共同沿堆叠装置1的长度方向移动。其中，第三驱动件611和第四驱动件612可以分别为驱动气缸。
在本申请的一些实施方式中，托盘40包括基板41，基板41的长度方向的两端分别设有一个夹持组件43。其中，夹持组件43包括连接板431、安装座432、滑杆433和弹簧434。两个安装座432间隔设置于基板41的表面，两个安装座432上分别穿设有一个滑杆433，滑杆433能够沿托盘40的长度方向运动，滑杆433靠近基板41的外侧边缘的一端与连接板431相连，从而通过连接板431带动滑杆433共同移动，滑杆433的另一端与安装座432间设有弹簧434，并在滑杆434朝向基板41的外侧方向的移动过程中挤压弹簧434。
托盘锁紧机构60包括第一锁紧组件61、第二锁紧组件62和锁紧件63。其中，第二锁紧组件62与第一锁紧组件61的结构相同。为描述方便，本申请仅以第一锁紧组件61为例进行举例说明。其中，第一锁紧组件61包括第三驱动件611、第四驱动件612和支撑板613。第三驱动件611设于机架10上，第三驱动件611的驱动端与支撑板613相连，第四驱动件612设于支撑板613上，第四驱动件612的驱动端与锁紧件63相连。当第三驱动件611的驱动端运动时，能够带动第四驱动件612和锁紧件63共同沿堆叠装置的高度方向运动，当第四驱动件62的驱动端运动时，能够带动锁紧件63沿堆叠装置1的长度方向运动。锁紧件63为具有豁口的条形板状结构，当锁紧件63与夹持组件43相连时。锁紧件63上的豁口刚好套设于连接板431上的两个滑杆433的外部，且在锁紧件63朝向托盘40的外侧的运动过程中，能够与连接板431相抵接，并带动连接板431和滑杆433共同朝向托盘41的外侧运动。
当多个电芯2被挤压堆叠成电芯模组3后，需要将电芯模组3转移至托盘40上。通过第三驱动件611驱动锁紧件63向上移动，为托盘40沿堆叠装置1的长度方向移动提供避让空间，托盘40从一端的锁紧件63的下方移动至支撑机构20的下方，并与第一开口23正对设置。此时通过第三驱动件611驱动锁紧件63向下移动，并使锁紧件63套设于滑杆433上。通过第四驱动件612驱动锁紧件63远离托盘40运动，锁紧件63在移动过程中与连接板431的相抵接并带动连接板431共同远离托盘40运动，从而增加了托盘40两端的滑杆433间的间距尺寸，从而能够将电芯模组3通过第一开口23转移至托盘40上。电芯模组3 转移至托盘40后，通过第四驱动件612驱动锁紧件63朝向托盘40的中心运动，并最终将两端的滑杆433抵接于电芯模组3的两侧，此时，弹簧434由于变形仍具有一定的弹力，从而通过电芯模组3两侧的弹簧434和滑杆433共同挤压电芯模组3，将电芯模组3固定于托盘40上。由于无需在托盘40上进行对多个电芯3的挤压，因此托盘40的尺寸可适当的减小。而夹持机构43仅用于固定电芯模组3，因此夹紧机构43上滑杆433的位移量以及弹簧434的伸缩量也可适当的减小，从而进一步地降低了托盘40的制造成本。
通过第三驱动件611驱动锁紧件63沿竖直方向运动，能够在托盘40的移动过程中进行避让，防止锁紧件63对托盘40造成干涉，影响托盘40的正常移动过程。通过第四驱动件612驱动锁紧件63带动夹持组件43共同沿堆叠装置1的长度方向移动，能够使电芯模组3顺利的放置于托盘40上，并通过夹持组件43固定夹紧，从而使电芯模组3相对托盘40的位置固定。
在本申请的一些实施方式中，结合图1、图3、图9和图11所示，图11是本申请一实施方式提供的升降机构70的结构示意图。堆叠装置1还包括升降机构70，升降机构70连接于机架10，升降机构70至少包括可升降运动的顶板71，托盘40上贯穿设有第二开口42，顶板71能够穿过依次穿过第二开口42和第一开口23并与电芯模组3相抵接。
具体地，顶板71为平板状结构，能够沿堆叠装置1的高度方向上下运动，从而用于支撑电芯模组3，并带动电芯模组3共同沿堆叠装置1的高度方向上下运动。
将多个电芯2挤压成电芯模组3后，控制升降机构70的顶板71依次穿过第二开口42和第一开口23并与电芯模组3的底面相抵接，通过顶板71对电芯模组3进行支撑，然后控制第一支撑件21和第二支撑件22相对远离并使第一开口23扩大，然后控制顶板71下降并带动电芯模组3穿过第一开口23，从而最终将电芯模组3放置于托盘40上，并通过托盘40对电芯模组3进行支撑，便于对电芯模组3进行转移。
在本申请的一些实施方式中，再次结合图1、图3、图9和图11所示，沿支撑机构20的轴向方向，顶板71的长度尺寸小于第二开口42的长度尺寸，并大 于电芯模组3的长度尺寸。
具体地，托盘40的基板41的中心位置设有第二开口42，以便顶板71穿设于第二开口42中，从而用于支撑电芯模组3并将电芯模组3转移至托盘40上。其中，第二开口42的长度方向与堆叠装置1的长度方向相一致。
在本申请的一些实施方式中，基板41上的第二开口42的宽度方向的两侧还分别设有支撑座44，支撑座44同样为L型机构，通过两侧的支撑座44共同对电芯模组3进行支撑。当两个支撑座44间的开口尺寸大于基板41上的开口尺寸时，顶板71的运动受基板41上的开口尺寸限制，此时基板41上的开口即为第二开口42。当两个支撑座44间的开口尺寸小于基板41上的开口尺寸时，顶板71的运动受两个支撑座44间的开口尺寸限制，此时两个支撑座44间的开口即为第二开口42。
将顶板71的长度尺寸小于第二开口42的长度尺寸设置，能够保证顶板71在升降过程中顺利穿过第二开口42，将顶板71的长度尺寸大于电芯模组3的长度尺寸设置，能够保证在电芯模组3的长度范围内，完全对电芯模组3进行支撑，防止由于电芯模组3的下方由于缺少支撑，而在转移至托盘40的过程中发生跌落现象。
在本申请的一些实施方式中，再次结合图1、图3、图9和图11所示，沿垂直于支撑机构20的轴向的方向，第二开口42的宽度尺寸小于电芯模组3的宽度尺寸。
具体地，第二开口42的宽度方向与堆叠装置2的宽度方向相一致。
由于顶板71的长度尺寸小于第二开口42的长度尺寸，并大于电芯模组3的长度尺寸，因此电芯模组3的长度尺寸小于第二开口42长度尺寸，通过将第二开口42的宽度尺寸小于电芯模组3的宽度尺寸设置，能够通过第二开口42宽度方向的两侧的部分结构对电芯模组3进行支撑，有效地防止电芯模组3通过第二开口42掉落。
在本申请的一些实施方式中，再次结合图1、图3、图9和图11所示，升降机构70还包括安装板72和第五驱动件73，安装板72与机架10相连，第五驱动件73固定于安装板72并与顶板71驱动连接，用于驱动顶板71升降运动。

通过压板33挤压电芯2，能够将多个电芯2挤压成电芯模组3，同时压板33的受力面大，能够防止在挤压电芯2的过程中由于应力集中，造成电芯2的损坏。
在本申请的一些实施方式中，结合图1、图2、图3和图7所示，第一支撑件21包括第一支撑底板211和第一支撑侧板212，第一支撑底板211和第一支撑侧板212相连且形成L型结构；和/或，第二支撑件22包括第二支撑底板和第二支撑侧板，第二支撑底板和第二支撑侧板相连且形成L型结构。

第二方面，本申请提出了一种电芯模组3的堆叠方法。结合图1至图6，以及图13所示，图13是本申请一实施方式提供的堆叠方法的流程图。在本申请的一些实施方式中，该堆叠方法根据上述任一实施方式的堆叠装置1进行实施，包括以下步骤：

其中，支撑机构20、压紧机构30、托盘40以及电芯2之间的连接关系及工作过程已在上述堆叠装置1的描述中进行了公开，在此不再进行赘述。

具体地，通过第五驱动件73驱动顶板71沿堆叠装置1的高度方向向上运动，并与电芯模,3的底面相抵接，进一步地驱动顶板71向上运动，从而使电芯模组3脱离支撑机构20的支撑。然后为了便于顶板71带动电芯模组3向下运动并穿过第一开口23，通过伸缩机构驱动第一支撑件21和第二支撑件22相对远离，从而增大第一开口23的面积尺寸，进而使顶板71带动电芯模组3向下运动并穿过第一开口23。然后进一步地驱动顶板71向下运动并穿过第二开口42，当顶板穿过第二开口42后，电芯模组3的底面与托盘40相抵接，通过托盘40支撑电芯模组3，从而将电芯模组3由支撑机构20转移至托盘40上。然后驱动托盘40沿堆叠装置1的长度方向运动，进而移动至输送装置4上，并通过输送装置4将托盘40和电芯模组3输送至下一工序。
