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其他领域。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。
电池单体是组成电池的最小单元，具体地，多个电池单体之间可以通过串联或者并联或者混联组成一个电池模组，然后将一个或者多个电池模组相连，并组装形成电池。当然，多个电池单体也可以直接组装形成电池。其中，混联是指多个电池单体中既有串联又有并联。
在通过电池单体组成电池模组或者电池的过程中，通常需要在电池单体的表面贴胶，然后将多个电池单体沿厚度方向进行预堆叠，以使各电池单体之间能够紧密贴合，然后通过相邻的电池单体表面上的胶纸实现胶粘固定。
然而，目前的预堆叠过程，预堆叠程序复杂且稳定性差，不仅会导致多个电池单体发生同时歪倒，并且堆叠效率也大大降低，影响电池单体预堆叠过程的效率，甚至影响由电池单体组装形成的电池模组或者电池的结构稳定性。
基于以上考虑，为了解决目前电池单体在预堆叠过程预堆叠效率低且稳定性较差的问题，本申请的一个或多个实施例中提供了一种预堆叠装置，该预堆叠方法能够在对电池进行稳定的预堆叠后，再将其取出，实现了自动化稳定堆叠，从而提高生产效率、降低成本。
参见图1至图4，本申请提供了一种预堆叠装置100，预堆叠装置100包括安装座10、托盘20、以及推动组件50。安装座10包括至少一个工位，托盘20设置于安装座10上，托盘20用于承载至少两个沿自身厚度方向L1排列的电池单体200，推动组件50沿电池单体200的厚度方向L2可移动地设置于其中一个工位上，其中，推动组件50用于在对应工位上沿电池单体200的厚度方向L2驱动托盘20上的电池单体200移动，以使每相邻两个电池单体200相互贴合。
安装座10是指能够为托盘20、以及推动组件50提供安装基础的结构。托盘20是指设置于安装座10上的，能够为至少两个电池单体200提供支撑及堆叠空间的结构，可以通过外部机械手或者搬运装置，沿电池单体200的厚度方向L1，夹持多块电池单体200，并将其放置于托盘20上，此时由于电池单体200并不受力，因此其排列较为松散，并未形成紧密堆叠。
而后，通过控制托盘20运动，使得托盘20运动至推动组件50所在工位，电池单体200在进行堆叠时，通常是设置极柱的一侧朝上设置。此时，电池单体200的高度方向L3是指由设置有极柱的一侧表面指向与其相对的另一侧表面的方向，电池单体200的宽度方向L2是指垂直于电池单体200的高度方向L3且平行于电池单体200的大面的方向，电池单体200的厚度方向L1是指垂直于电池单体200的大面的方向。其中，电池单体200的大面通常是指电池单体200上面积最大的一侧表面。
当推动组件50向电池单体200上施加压力，推动组件50首先与其中一个电池单体200的大面接触，而后持续沿多个电池单体200的厚度方向L1持续推动，够平衡电池单体200与其支撑面之间的摩擦力，从而使得多个电池单体200的大面与大面最直接接触，电池单体200与电池单体200之间保持平衡，完成稳定地预堆叠，避免电池单体200歪倒。
推动组件50在对电池单体200进行推动时，其可以是形成与电池单体200的大面的面与面直接接触，也可以形成球状结构对电池单体200的大面进行抵接。值得注意的是，推动组件50对电池单体200的接触以及在预堆叠过程中的用力，需保证不破坏电池单体200。
本申请提供的预堆叠装置100，能够在托盘20及其托盘上的电池单体200在运动至推动组件50所在工位的时候，通过推动组件50的推动操作，实现多个电池单体200沿自身厚度方向L2上的紧密堆叠。
可以理解地，当堆叠完成之后，可以将托盘20及其上堆叠完成的电池单体200移走，进行下一步操作。
在一些实施例中，参见图1至图4，安装座10的工位包括沿周向间隔设置的第一工位11、第二工位13及第三工位14，托盘20被构造为能够在第一工位11、第二工位13及第三工位14之间旋转；
第一工位11用于托盘20上料电池单体200，推动组件50设于第二工位13上，第三工位14用于下料托盘20上相互贴合后的电池单体200。、
第二工位13是指安装座10上的用于加压堆叠多个电池单体200的工位，具体地，将电池单体200从上一工序移动至第二工位13上，并将多个电池单体200在第二工位13沿厚度方向L1依次堆叠，即可实现电池单体200的预堆叠，以使多个电池单体200之间能够相互紧密贴合的工位。
第一工位11、第二工位13与第三工位14之间可以通过安装座10的转动或者移动或 者其他运动方式相互转换，托盘20可以从第一工位11运动至第二工位13再运动至第三工位14，而后再从第三工位14回到第一工位11，托盘20从第一工位11转动一圈，回位至第一工位11的过程，称为一次预堆叠流程，外部机械手或者搬运装置可以向第一工位11的托盘20上放置电池单体200，也可以将第三工位13上的电池单体200取走。
当多个电池单体200沿自身厚度方向L1被松散的放置于第一工位11之后，通过控制托盘20运动，使得托盘20从第一工位11运动直至第二工位13，当托盘20位于第二工位13，第二工位13上的推动组件50向电池单体200上施加压力，完成预堆叠，避免电池单体200歪倒。
而后，控制完成预堆叠后的托盘20及其上的电池单体200运动至第三工位14，此时可以通过外部设备将托盘20上已经堆叠完成的多个电池单体200取走，以进行下一步工艺流程。在第三工位14的托盘20上的电池单体200被取走之后，可以控制托盘20继续运动回位装置第一工位11，以进行下一次的预堆叠流程。
如此，本申请的预堆叠装置100，形成简单的多工位堆叠程序，实现电池单体200的上料、堆叠、及下料过程，不同工位间取放电池单体200互不影响，将预堆叠分解为多个步骤，且形成循环进行，实现自动预堆叠，使得电池单体200的预堆叠效率提高，预堆叠稳定性好，不同工位间同步生产，互不影响，提高生产效率。
可以理解地，安装座10上的工位也可以包括除第一工位11、第二工位13及第三工位14之外的工位，本申请在此不做限定。
在一些实施例中，参见图1及图2，安装座10包括底座15及可转动地设置于底座15上的支撑件16，底座15上具有沿自身周向间隔设置的第一工位11、第二工位13及第三工位14，托盘20包括多个且均设于支撑件16上并随支撑件16转动，当其中一个托盘20运动至第一工位11，第二工位13、及第三工位14上均有一个托盘20。
具体地，支撑件16可以设置为一转盘，根据底座15上设置的第一工位11、第二工位13及第三工位14之间的位置关系，可对应地在支撑件16上周向间隔设置三个托盘20。当支撑件16带动其上的三个托盘20转动至其中一个托盘20至第一工位11时，另外的两个托盘20分别位于第二工位13和第三工位14上。
如此，每个托盘20均可以从第一工位11进行上料、第二工位13进行预堆叠，第三工位14进行下料，且多个托盘20在同时刻不同工位间同步生产，当第一工位11上的托盘20在上料时，第四工位12上的托盘20进行预堆叠，第二工位13上的托盘20进行下料，周而复始，互不影响，从而提高生产效率。
在一些实施例中，参见图1及图2，安装座10还具有第四工位12，第四工位12间隔设于第一工位11和第二工位13之间，当托盘20位于第四工位12，至少两个电池单体200沿自身的厚度方向L1预堆叠于托盘20上。
电池单体200排列的方向可不同，每个电池单体200均具有两个大面，当两个大面的朝向不同，则电池单体200的正极柱和负极柱的摆放位置则不同，从而形成互为配方电芯的两电池单体200。即此时互为配方电芯的两个电池单体200，假设其中一个电池单体200的正极柱在左边负极柱在右边，则另一个电池单体200相当于将其绕高度方向L3旋转180度，从而形成正极柱在右边负极柱在左边的摆放方式。
在预堆叠流程完成之后，电池单体200需要被移动至不同的位置，因此，为了提高后续的装配效率，可以在托盘20上形成第一区域和第二区域，在托盘20处于第一工位11时，将互为配方电芯中的一者电池单体200放置于第一区域上，当托盘20位于第四工位12时，将互为配方电芯中的另一者电池单体200放置于第二区域上，并且在托盘20运动至第二工位13上后，分极性对电池单体200进行预堆叠，以保证当托盘20运动至第三工位14后，操作人员可以根据所需进行取料。
当然地，也可以在第一工位11和第四工位12进行正极柱和负极柱排列的方向完全相同的同一摆放方向的电池单体200的上料，如此，可以进行多次上料，避免一次上料过多造成的电池单体200的歪倒。
在一些实施例中，参见图1及图2，预堆叠装置100还包括定位组件50，定位组件50设于第一工位11，定位组件50用于将托盘20固定于第一工位11。
定位组件50可以是驱动结构加定位凸起的组合，并在支撑件16或者托盘20的相应位置设置凹槽，当支撑件16带动其上的托盘20旋转时，其中一个托盘20运动至第一工位11时，驱动结构驱动定位凸起伸出，卡嵌于凹槽内，停下支撑件16，此时托盘20被稳定固定于第一工位11进行上料。
在上料完成之后，驱动结构还可以驱动定位凸起收回，此时支撑件16继续转动，直至刚刚正在第一工位11上料完成后的托盘20运动至第四工位12，此时另一个托盘20运动至第一工位11进行上料，而第四工位12的托盘20则进行第四工位12的上料，以此类推。
进一步地，也可以在托盘20和定位组件50上设置感应装置，当定位组件50感应到托盘20后，立即驱动定位凸起伸出以停转支撑件16。
如此，本申请通过定位组件50的设置，可以实现第一工位11的自动定位，自动停下托盘20进行各个工位的操作。
在一些实施例中，参见图1、图2及图5和图6，预堆叠装置100还包括第一夹持组件30，第一夹持组件30被配置为沿电池单体200的高度方向L3可移动地设置于安装座10上。第一夹持组件30能够在托盘20运动至第二工位13时，沿电池单体200的宽度方向L2夹持托盘20上的各电池单体200，电池单体200的宽度方向L2与厚度方向L1垂直。
具体地，当托盘20运动至第二工位13时，第一夹持组件30可沿电池单体200的高度方向L3下降，电池单体200的高度方向L3与电池单体200的宽度方向L2及均厚度方向 L1垂直，直至第一夹持组件30能够沿电池单体200的宽度方向L2顺利夹持电池单体200的上侧，以便于通过推动组件50对电池单体200进行加压。
当托盘20未运动至第二工位13时，第一夹持组件30不需要对电池单体200进行夹持，则此时，第一夹持组件30沿电池单体200的高度方向L3上升，远离支撑件16，直至不影响托盘20上的电池单体200跟随托盘20在工位之间进行运动。
通过第一夹持组件30在电池单体200的高度方向L3上的可移动设置，使得第一夹持组件30可以在电池单体200运动至第二工位13时顺利实现对电池单体200的夹持，保证推动组件50的推定的有效性。并且，第一夹持组件30在其他情况下不影响电池单体200跟随托盘20运动，能够顺利实现电池单体200在多个工位之间的运动。
在一些实施例中，参见图3及图4，预堆叠装置100还包括第二夹持组件40，第二夹持组件40设置于托盘20上，并用于沿电池单体200的宽度方向L2夹持托盘20上的各电池单体200。第一夹持组件30沿电池单体200的高度方向L3与第二夹持组件40间隔设置。
当电池单体200被放置于托盘20上，先通过第二夹持组件40原电池单体200的宽度方向L2对托盘20上的电池单体200进行夹持，而后在整个预堆叠流程中，保持对电池单体200的夹持，避免电池单体200在放置于托盘20上之后产生歪倒。
当托盘20由运动至第二工位13时，第一夹持组件30在第二工位13上沿电池单体200的高度方向L3与第二夹持组件40间隔设置。由此，第一夹持组件30可以在第二工位13再次沿电池单体200的宽度方向L2对电池单体200进行夹持，此时第二夹持组件40与第一夹持组件30沿电池单体200的高度方向L3分别夹持电池单体200的高度上的不同位置，如底端和中端，或者中端和顶端。
第二夹持组件40与第一夹持组件30能够沿电池单体200的高度方向L3相互间隔，并同时对电池单体200高度方向L3上的相对两端进行夹持固定，由此能够平衡电池单体200与其支撑面之间的摩擦力，使电池单体200的预堆叠过程更加顺利，降低电池单体200在预堆叠过程中发生歪倒的概率，使得电池单体200的堆叠更加稳定。
在一些实施例中，第一夹持组件30及第二夹持组件40均包括沿电池单体200的宽度方向L2分别设置于托盘20两侧的第一夹持件41及第二夹持件42，第一夹持件41与第二夹持件42中的至少一者被配置为沿电池单体200的宽度方向L2可移动地设置。
具体地，第二夹持组件40中的第一夹持件41与第二夹持件42可以分别通过伸缩气缸设置于托盘20的两侧，使得第一夹持件41与第二夹持件42能够实现沿电池单体200的宽度方向L2相互靠近或者相互远离。当电池单体200放置于托盘20上时，第一夹持件41与第二夹持件42相互靠近并夹持电池单体200。当需要将电池单体200从托盘20中取出时，则第一夹持件41与第二夹持件42相互远离。
通过设置第一夹持件41与第二夹持件42，可以实现对电池单体200的顺利夹持，从 而使电池单体200可以稳定设置于托盘20上，并且使电池单体200在加压过程中能够保持平衡。
并且，设置第一夹持件41和第二夹持件42，能够使得第一夹持组件30和第二夹持组件40适配夹持多种不同宽度的电池单体200，通过同一个预堆叠装置100实现不同尺寸电池单体200预堆叠，换型(不同电池单体200型号)方便。
在一些实施例中，参见图5及图6，第一夹持组件30还包括主体31及第一驱动件32，第一驱动件32连接于主体31与安装座10之间，并用于驱动主体31沿电池单体200的高度方向L3移动。其中，第一夹持组件30中的第一夹持件41及第二夹持件42设置于主体31上，推动组件50沿电池单体200的厚度方向L1可移动地与主体31连接。
具体地，主体31可以为第一驱动件32、推动组件50、第一夹持件41以及第二夹持件42提供安装基础。第一驱动件32可以但不限于设置为下压气缸，用于驱动主体31并带动主体31上的第一夹持件41与第二夹持件42沿电池单体200的高度方向L3移动，推动组件50可以在主体31上移动以靠近或者远离托盘20上的电池单体200。
通过设置主体31及第一驱动件32，可以带动第一夹持件41及第二夹持件42沿电池单体200的高度方向L3移动，从而在加压时对电池单体200进行夹持固定，并在不需要加压时对电池单体200形成避让。
进一步地，第一夹持组件30还包括升降件34，第一驱动件32与升降件34驱动连接，升降件34穿过主体31与第一夹持组件30连接，当第一驱动件32驱动升降件34上下移动，第一夹持组件30被带动上下移动。
如此设置可以将第一驱动件32和第一夹持组件30设置在主体31的相对两侧，合理利用装配空间。
在一些实施例中，第一夹持组件30还包括设置于主体31上，并位于第一夹持件41与第二夹持件42之间的限位组件33，限位组件33用于沿电池单体200的高度方向L3抵压托盘20上的各电池单体200。
当第一夹持件41及第二夹持件42沿电池单体200的宽度方向L2对电池单体200的上侧进行夹持时，限位组件33位于第一夹持件41及第二夹持件42之间，并能够向下抵压电池单体200，使电池单体200稳定支撑于托盘20的支撑面上。由此，电池单体200在预堆叠过程中能够更加稳定。
在一些实施例中，参见图5至图7，限位组件33包括调节件331与抵压件332，调节件331沿电池单体200的高度方向L3可伸缩地连接于主体31与抵压件332之间，抵压件332用于沿电池单体200的高度方向L3抵压托盘20上的各电池单体200。
具体地，调节件331可以但不限于设置为弹簧，弹簧弹性连接于主体31与抵压件332之间，使得抵压件332能够弹性抵压于电池单体200上。
进一步地，调节件331与抵压件332均可以设置为多个，并且调节件331与抵压件332一一对应设置。
需要说明的是，每一个电池单体200上均凸出设置有极柱，并且由于机械误差，不同的电池单体200的极柱高度之间都可能存在一定的误差。由此，每一个抵压件332及调节件331可以对应抵压于一个电池单体200的极柱。并且每一个抵压件332在调节件331的伸缩作用下，可以自适应的抵压于对应的电池单体200的极柱上，使得抵压件332对于每一个电池单体200的抵压作用更加稳定。
通过设置调节件331与抵压件332，能够柔性且稳定的将电池单体200抵压于托盘20上，使得推动电池单体200的过程中，电池单体200可以保持平衡。
在一些实施例中，参见图5至图7，抵压件332包括连接部3321与滚动部3322，连接部3321与调节件331相连，滚动部3322沿电池单体200的厚度方向L1可滚动地设置于连接部3321上，并用于沿电池单体200的高度方向L3与托盘20上的各电池单体200滚动抵压。
当抵压件332包括多个时，每一个抵压件332均包括连接部3321与滚动部3322。具体地，滚动部3322可以但不限于设置为滚轮，将滚轮滚动设置于连接部3321上。当抵压件332抵压于电池单体200上时，推动组件50沿电池单体200的厚度方向L1对电池单体200施加压力，使得电池单体200沿厚度方向L1相互靠拢贴合。
与此同时，当电池单体200在推力作用下沿厚度方向L1发生位移时，滚动部3322可以与电池单体200滚动抵压，使得对于电池单体200的抵压更加稳定，并且不影响电池单体200在厚度方向L1上的移动。
通过设置滚动部3322，使得抵压件332可以与电池单体200之间实现滚动抵压，在电池单体200沿厚度方向L1相互靠拢移动时能够持续施加抵压力，使抵压过程更加稳定。
在一些实施例中，参见图3至图5，推动组件50包括抵靠件51及推动件52，抵靠件51设置于托盘20上，推动件52沿电池单体200的厚度方向L1可移动地设置于安装座10上，且抵靠件51与推动件52沿电池单体200的厚度方向L1分别位于托盘20的两侧，推动件52被配置为能够沿电池单体200的厚度方向L1推动托盘20上的各电池单体200抵靠于抵靠件51上。
具体地，抵靠件51为设置于托盘20上的挡板。当电池单体200随着托盘20运动至第二工位13时，推动件52与抵靠件51沿电池单体200的厚度方向L1分别位于电池单体200的两侧。推动件52沿电池单体200的厚度方向L1发生移动，并沿电池单体200的厚度方向L1对电池单体200施加推力，使得多个电池单体200之间能够紧密贴合。
进一步地，推动件52可以但不限于设置为加压气缸。当电池单体200沿厚度方向L1排列在托盘20上时，推动件52伸出，并在电池单体200的大面上施加一推力，从而使得多个电池单体200之间能够紧密贴合。
通过抵靠件51与推动件52之间的相互配合，能够顺利实现多个电池单体200之间的预堆叠，使电池单体200沿其厚度方向L1紧密贴合，以便于后续进行组装。
在一些实施例中，参见图3至图4，预堆叠装置100还包括检测组件60，检测组件60设于托盘20上。检测组件60用于检测托盘20上是否有电池单体200。
检测组件60可以是红外检测结构等等，可以理解地，若托盘20上未放置电池单体200，则此时推动件52若还按照相同的程序进行推动，则有可能产生与抵靠件51的直接碰撞。
通过检测组件60的设置，可以根据检测组件60的检测结构智能控制推动组件50，避免产生安全事故。
基于与上述预堆叠装置100相同的构思，本申请还提供了一种电池加工设备，包括如上的预堆叠装置100。
参见图8，基于与上述预堆叠装置100相同的构思，根据一个或多个实施例，本申请提供了一种预堆叠方法，包括下述步骤：
S10、控制托盘20运动至安装座10的第一工位11，并将至少两个电池单体200沿自身的厚度方向L1放置于托盘20上；
S30、控制托盘20运动至安装座10的第二工位13，并控制推动组件50沿电池单体200的厚度方向L1驱动托盘20上的电池单体200移动，以使每相邻两个电池单体200相互贴合；
S40、控制托盘20运动至安装座10的第三工位14，并从托盘20上取走电池单体200；
其中，第一工位11、第二工位13及第三工位14间隔设于安装座10的周向。
具体地，关于安装座10、托盘20及推动组件50的具体结构设置，已经在上文中进行详述，此处不再赘述。
如此，本申请通过上述方法，形成简单的多工位堆叠程序，实现电池单体200的上料、堆叠、及下料过程，不同工位间取放电池单体200互不影响，将预堆叠分解为多个步骤，且形成循环进行，实现自动预堆叠，使得电池单体200的预堆叠效率提高，预堆叠稳定性好，不同工位间同步生产，互不影响，提高生产效率。
在一些实施例中，参见图8，步骤S10中在控制托盘20运动至安装座10的第一工位11之后，还包括以下步骤：
S20、控制托盘20运动至安装座10的第四工位12，并将至少两个电池单体200沿自身的厚度方向L1放置于托盘20上；
其中，第四工位12沿周向间隔设于第一工位11与第二工位13之间。
参见上文中的记载，本申请的预堆叠装置100不仅可以实现配方电芯的同时堆叠和下料，也可以实现同一摆放方向的电池单体200的多次上料，避免一次上料过多造成的电池单体200的歪倒。
在一些实施例中，步骤S10中将至少两个电池单体200沿自身的厚度方向L1放置于托盘20上之后，还包括：
S50、沿电池单体200的宽度方向L2夹持托盘20上的各电池单体200，电池单体200的宽度方向L2与电池单体200的厚度方向L1垂直。
具体地，可通过设置第一夹持组件30沿宽度方向L2对电池单体200进行夹持，关于第一夹持组件30的具体结构以在上文中进行详述，此处不再赘述。
进一步地，步骤S30和S50可同时进行，也可以在步骤S50执行完夹持操作之后，再进行步骤S30的推动。如此，可以在电池单体200运动至第二工位13时顺利实现对电池单体200的夹持，保证推动组件50的推定的有效性。并且，第一夹持组件30在其他情况下不影响电池单体200跟随托盘20运动，能够顺利实现电池单体200在多个工位之间的运动。
根据一个或多个实施例，首先通过外部机械手将多个电池单体200依次移动至第一工位11的托盘20上，通过第二夹持组件40对该托盘20上的各电池单体200的下侧进行夹持，使其稳定设置于托盘20上。转动支撑件16，并将托盘20及其上的电池单体200移动至第四工位12，通过外部机械手将配方电芯置于托盘20上。
随着支撑件16的继续转动，当其托盘20转动至第二工位13时，控制第一夹持组件30下降，通过第一夹持组件30对电池单体200的上侧进行夹持固定。与此同时，抵压件332在调节件331的作用下，自适应的抵压于对应的电池单体200的极柱上。
抵压稳定之后，控制推动件52朝向电池单体200移动，在电池单体200的大面上施加一推力。在推力的作用下，多个电池单体200沿厚度方向L1相互靠拢，并且抵靠在抵靠件51上，直至多个电池单体200之间紧密贴合。此时，完成该托盘20上电池单体200的预堆叠。继续转动支撑件16，将其运转至第三工位14，并通过机械手进行取料，同时对下一个托盘20上的电池单体200执行推动操作，如此循环。
