在本申请实施例的描述中，除非另有明确的规定和限定，技术术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；也可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请实施例中的具体含义。
在本申请实施例的描述中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
本申请中，电池单体可以包括锂离子二次电池单体、锂离子一次电池单体、锂硫电池单体、钠锂离子电池单体、钠离子电池单体或镁离子电池单体等，本申请实施例对此并不限定。电池单体可呈圆柱体、扁平体、长方体或其它形状等，本申请实施例对此也不限定。电池单体一般按封装的方式分成三种：柱形电池单体、方体方形电池单体和软包电池单 体，本申请实施例对此也不限定。
本申请的实施例所提到的电池是指包括一个或多个电池单体以提供更高的电压和容量的单一的物理模块。例如，本申请中所提到的电池可以包括电池模块或电池包等。电池一般包括用于封装一个或多个电池单体的箱体。箱体可以避免液体或其他异物影响电池单体的充电或放电。
电池包括多个依次排列的电池单体。为了固定电池单体，电池设置有两个端板和扎带，两个端板分别设置于多个电池单体沿排列方向的两端，扎带环绕在端板和电池单体构成的整体的外侧，以固定端板和电池单体。
发明人发现在电池的捆扎过程(即捆绑扎带的过程)中，电池内部结构之间容易发生错位，导致捆扎后形成的电池内部结构之间易发生错位等问题后，便对电池的捆扎工艺及相关装置进行了***的分析研究。发明人发现，由于捆扎工艺是绕电池的一周进行捆扎的，因此，在捆扎的过程中无法采用机器对电池进行夹紧。通常采用人工的方式对电池进行捆扎，以在捆扎电池的同时，通过人工的方式夹紧电池，以对电池内部各部件进行整形，尽量的降低电池内部部件之间的错位。然而采用人工方式进行捆扎电池，捆扎的效率较低，且人工捆扎的方式依然存在电池内部各部件之间错位的风险。
基于发明人发现的上述问题，发明人对电池的定位装置的结构进行了改进，本申请实施例描述的技术方案适用于电池定位装置以及采用电池定位装置对电池进行定位的方法。
如图1所示，电池10包括层叠设置的电池单体30以及围绕电池单体30设置的绑带20，绑带20可以有不同的种类，示例性地，绑带20可以包括钢带和尼龙带。在对电池10进行捆扎绑带20的过程中，需要对电池10进行良好的定位，以防止电池10在捆扎的过程中，电池单体30之间，以及电池单体30与端板之间发生窜动，而影响捆扎后形成的电池10的整体结构的稳定性。
如图2和图3分别示出了本申请实施例提供的电池定位装置40放置有电池10的主视图和结构示意图。
如图2和图3所示，根据本申请实施例提供的电池定位装置40，电池定位装置40用于夹持电池10，电池10包括第一夹持面10a和第二夹持面10b，第一夹持面10a和第二夹持面10b沿第一方向X上的投影不重合，第一方向X垂直于第一夹持面10a和第二夹持面10b。电池定位装置40包括托盘41和限位机构42，托盘41用于放置电池10。限位机构42设置于托盘41，用于在沿第一方向X夹持电池10的第二夹持面10b时松开电池10的第一夹持面10a。
可选地，电池10沿第二方向Y放置于托盘41上，第一方向X可以与第二方向Y垂直。示例性地，第二方向Y为铅垂方向，第一方向X为水平方向。
设置电池10的第一夹持面10a和第二夹持面10b沿第一方向X上的投影不重合，即设置第一夹持面10a和第二夹持面10b沿第一方向X的投影至少部分不重合，可以完全没有重合，即二者在第一方向X的投影邻接或者间隔设置。也可以有部分重合，但不是完全重合。如此限位机构42在沿第一方向X夹持第一夹持面10a和第二夹持面10b时，只需要分别夹持二者在第一方向X上的投影没有重合的部分即可。
第一夹持面10a和第二夹持面10b可以分布在垂直于第一方向X的同一个平面内，也可以分布在垂直于第一方向X的不同平面内，这里不做限制，可以根据电池10的具体结构进行设置。
托盘41作为电池10的承载部件，其结构型式不做限制，只要能够承受电池10的重力，且不影响后续电池10的捆扎工艺的正常进行即可。示例性地，托盘41可以板状件或者块状件形成的平面后者台阶面，也可以是由条状件组合形成的具有承载平面或者承载台阶面的结构。
限位机构42沿第一方向X靠近电池10时，限位机构42可以同时夹持第一夹持面10a和第二夹持面10b，以对待捆扎的电池10沿第一方向X进行整形。而在限位机构42对电池10进行泄压时，可以先泄压第一夹持面10a，而保持对第二夹持面10b的夹紧状态。
在限位机构42对第一夹持面10a泄压，而保持对第二夹持面10b的夹持状态下，由于有限位机构42夹持第二夹持面10b，无需再对电池10 进行重复夹持，此时可以采用机器对电池10进行捆扎，由于第一夹持面10a没有被夹持，则可以绕电池10经过第一夹持面10a的位置进行捆扎。如此设置，可以不用使用人工一边夹紧电池10一边对电池10进行捆扎，在对电池10进行捆扎的过程中，可以降低电池10内部各部件错位的可能性，提高加工形成的电池10的结构稳定性。
而在完成对第一夹持面10a的捆扎后，缠绕形成的第一绑带对电池10形成一定的限位，此时，可以使限位机构42对第二夹持面10b进行泄压，利用第一绑定对电池10形成的限位作用，采用机器对电池10进行经过第二夹持面10b的捆扎。如此，经过两次捆扎，可以实现对电池10的有效捆扎，且在捆扎的过程中，可以有效地降低电池10内部零部件发生错位的风险。
本申请实施例提供的电池定位装置40，通过设置限位机构42在第一方向X夹持电池10的第二夹持面10b时松开电池10的第一夹持面10a，即限位机构42对第一夹持面10a和第二夹持面10b限位后，分开泄压，如此可以使用机器分别对第一夹持面10a和第二夹持面10b进行捆扎，如此，在提高了电池10的生产效率的同时，还可以降低电池10在捆扎过程中内部零部件发生错位的可能性，提高生产形成的电池10的结构稳定性，进而提高电池10的使用寿命。
限位机构42的具体结构不做限制，只要能够形成对第一夹持面10a和第二夹持面10b的夹持，并分开泄压第一夹持面10a和第二夹持面10b即可。可选地，限位机构42可以是一个有机结合形成的机构，通过控制内部部件的运动关系，实现对第一夹持面10a和第二夹持面10b的夹持，并实现对第一夹持面10a和第二夹持面10b的分级泄压。另外，限位机构42可以包括两个独立的机构，分别独立地形成第一夹持面10a和第二夹持面10b的夹持和泄压动作。限位机构42还可以包括两个相互关联的机构，具体地，可以通过同一套驱动机构驱动二者分别对第一夹持面10a和第二夹持面10b进行夹持，而在泄压时，通过对驱动机构的控制，分别对第一夹持面10a和第二夹持面10b进行泄压。
在一些可选的实施例中，如图4和图5所示，限位机构42包括第一 限位机构421和第二限位机构422。第一限位机构421用于沿第一方向X夹持电池10的第一夹持面10a。第二限位机构422用于沿第一方向X夹持第二夹持面10b，并且第二限位机构422被配置为，第一限位机构421松开第一夹持面10a时，第二限位机构422能够夹持第二夹持面10b。
具体地，第一限位机构421和第二限位机构422可以同步或者不同步地分别对第一夹持面10a和第二夹持面10b进行夹持，第一限位机构421对第一夹持面10a泄压时，第二夹持机构依然能够保压，即第一限位机构421松开第一夹持面10a时，第二限位机构422依然能够夹持第二夹持面10b。
具体地，第一限位机构421和第二限位机构422可以通过同一驱动机构驱动二者分别夹持第一夹持面10a和第二夹持面10b。也可以设置第一夹持面10a和第二夹持面10b分别对第一夹持面10a和第二夹持面10b的夹持和保压。均可以实现对第一夹持面10a和第二夹持面10b的分级泄压的目的，以通过机器对电池10进行分别经过第一夹持面10a的和第二夹持面10b的捆扎。
可以理解的是，通过设置限位机构42包括第一限位机构421和第二限位机构422，便于对第一夹持面10a和第二夹持面10b的夹持操作，并便于对第一夹持面10a和第二夹持面10b分级泄压，简化电池的捆扎工艺中对电池的夹持和泄压操作。
在一些可选的实施例中，如图6和图7所示，电池定位装置40还包括锁止机构43，锁止机构43用于锁止第二限位机构422，以使第二限位机构422保持夹持第二夹持面10b的状态。
具体地，可以将第二限位机构422设置在电池10和第一限位机构421之间，在通过驱动装置驱动第一限位机构421朝向电池10的方向运动以夹持第一夹持面10a的过程中，第二限位机构422在第一限位机构421的推力的作用下随第一限位机构421朝向电池10的方向运动以夹持第二夹持面10b，而在第二限位机构422夹持第二限位面的动作到位后，通过锁止机构43锁止第二限位机构422，以使第二限位机构422保持对第二夹持面10b的夹持状态。此时，第二限位机构422不再需要第一限位机构 421的推力，可以通过驱动装置使第一限位机构421松开第一夹持面10a，即实现对第一夹持面10a的泄压，同时对第二夹持面10b进行保压。而在完成对电池10经过第一夹持面10a的捆扎后，松开锁止机构43，第二限位机构422回位，完成对第二夹持面10b的泄压。
可以理解的是，通过设置锁止机构43，可以使第一限位机构421和第二限位机构422通过同一套驱动装置分别完成对第一夹持面10a和第二夹持面10b的夹持动作，且通过锁止机构43实现对第二夹持面10b的保压，以实现对第一夹持面10a和第二夹持面10b的分级泄压。如此设置，有利于简化电池定位装置40的整体结构，且在生产过程中，简化捆扎过程中对电池定位装置40的操作步骤。
锁止机构43的具体结构不做限制，只要能够形成对第二限位机构422的限位作用，以形成第二限位机构422对第二夹持面10b的保压作用即可。
在一些可选的实施例中，第二限位机构422具有锁止部422a。锁止机构43包括限位齿条431和锁止驱动组件432。限位齿条431用于与锁止部422a配合，以限制第二限位机构422沿第一方向X的位移。锁止驱动组件432用于驱动限位齿条431沿朝向或者背离第二限位机构422的方向移动，以使限位齿条431与锁止部422a配合或者脱离配合。
具体地，锁止部422a可以是与限位齿条431的齿形相配合的齿形，第二限位机构422夹紧第二夹持面10b的状态下，锁止驱动组件432驱动限位齿条431朝向第二限位机构422的方向移动，以使限位齿条431与第二限位件4221的锁止部422a配合，限位齿条431保持与限位部的配合关系，则第二限位部保持对第二夹持面10b的夹持状态。此时对第一限位机构421卸压，第一限位机构421松开第一夹持面10a，不会影响第二夹持面10b继续保持对第二夹持面10b的夹持状态。
可以理解的是，设置第二限位机构422具有锁止部422a，并设置锁止机构43具有限位齿条431，通过锁止部422a与限位齿条431的配合实现对第二限位机构422的限位，由于限位齿条431具有多个限位齿，对于沿第一方向X具有不同尺寸的电池10，均可以通过限位齿条431的限位齿 与锁止部422a的配合，实现对第二限位机构422限位，以实现对不同尺寸电池10的第二夹持面10b的夹持，可以提高电池定位装置40对不同型号产品的适应性。
在另一些可选的实施例中，第二限位机构422与锁止机构43的配合形式也可以是卡槽与挡块的配合形式，或者仅设置锁止机构43沿第一方向X夹紧第二限位机构422，均能够实现锁止机构43对第二限位机构422的限位作用
锁止驱动组件432可以是电机，如伺服电机、步进电机等，通过电机的正反转实现限位齿条431沿朝向或者背离第二限位机构422的方向移动。锁止驱动机构还可以是气缸等结构，通过气缸的伸缩运动，实现限位齿条431沿朝向或者背离第二限位机构422的方向移动。或者锁止驱动机构仅单向驱动限位齿条431朝向第二限位机构422的方向移动，而通过弹性力或者外力实现限位齿条431的复位。上述设置方式，均能够实现锁止机构43对第二限位机构422的锁止或者解锁。
在一些可选的实施例中，锁止驱动组件432包括驱动气缸。可以设置限位齿条431与驱动气缸的活塞杆，通过活塞杆的伸缩运动实现锁止机构43锁止或者解锁第二限位机构422。
在一些进一步的实施例中，锁止驱动组件432还包括第一固定件和第一弹性件4321。第一弹性件4321连接第一固定件和限位齿条431。驱动气缸用于驱动限位齿条431朝向第二机构的方向移动，并使第一弹性件4321产生形变，以存储弹性势能。
具体地，驱动气缸的活塞杆伸出运动时，驱动限位齿条431朝向第二限位机构422的方向移动，第一弹性件4321在限位齿条431的所用下，产生形变并储存弹性势能。驱动气缸的活塞杆回位时，第一弹性件4321的弹性势能得到释放，驱动限位齿条431回位，以释放第二限位机构422。
第一弹性件4321产生的形变可以是拉伸形变，也可以是压缩形变。示例性地，第一固定件可以设置于托盘41，此时，驱动气缸的活塞杆驱动限位齿条431沿朝向第二限位件4221的方向移动的过程中，第一弹 性件4321产生压缩形变。或者，第一固定件也可以设置于锁止机构43，如驱动气缸的缸筒等，此时，驱动气缸的活塞杆驱动限位齿条431沿朝向第二限位件4221的方向移动的过程中，第一弹性件4321产生拉伸形变。
第一弹性件4321可以是弹簧、橡胶等结构，这里不做限制。
可以理解的是，设置锁止驱动机构包括第一弹性件4321的技术方案，可以简化锁止驱动组件432的结构，也使得限位齿条431的运动更加简单。
在一些实施例中，如图8所示，第一限位机构421包括第一限位件4211和限位驱动组件4212，第一限位件4211用于夹持第一夹持面10a，限位驱动组件4212用于驱动第一限位件4211沿第一方向X移动。第二限位机构422设置于第一限位件4211靠近电池10的一侧，第一限位件4211带动第二限位机构422的至少部分沿第一方向X移动，以使第二限位机构422夹持第二夹持面10b。
也就是说，由于第二限位机构422设置于第一限位件4211靠近电池10的一侧，在限位驱动组件4212驱动第一限位件4211沿朝向电池10的方向移动以夹持第一夹持面10a的过程中，第二限位机构422在第一限位件4211的推动作用下，也朝向电池10的方向移动，以夹持第二夹持面10b。而在第二限位机构422被锁止机构43锁止后，可以通过限位驱动机构的回位运动，使第一限位件4211回位，松开对第一夹持面10a的夹持，此时，第二限位机构422由于锁止机构43的锁止作用，依然保持对第二夹持面10b的夹持，即可实现对第一夹持面10a的泄压，而对第二夹持面10b的保压。
如此设置，通过一个限位驱动组件4212实现第一限位件4211和第二限位机构422分别夹持第一夹持面10a和第二夹持面10b，简化电池定位装置40的结构。
在完成对第一夹持面10a的捆扎后，解锁锁止机构43，第二限位机构422可以回位。可以借助外力如人力的作用使第二限位机构422回位，或者设置对应的回位驱动机构，以在锁止机构43解锁后，驱动第二限位机构422回位。
在一些可选的实施例中，如图9所示，第二限位机构422包括第二限位件4221、第二弹性件4222和第二固定件4223，第二弹性件4222连接第二限位件4221和第二固定件4223。第一限位件4211被配置为带动第二限位件4221沿第一方向X移动，并带动第二弹性件4222产生形变，以存储弹性势能。
具体地，第二限位件4221在第一限位件4211的推动作用下朝向电池10的方向移动，在此过程中，第二限位件4221带动第二弹性件4222产生形变，以储存弹性势能。第二限位件4221在锁止机构43的锁止作用下，保持对第二夹持面10b的夹持状态，同时，第二弹性件4222储存的弹性势能得以保存。而在锁止机构43解锁后，第二弹性件4222的弹性势能得到释放，第二限位件4221在第二弹性件4222的作用下回位。
第二弹性件4222的产生形变以储存弹性势能的过程中，可以产生拉伸形变，可以产生压缩形变，这里不做限制。示例性地，第二固定件4223设置于第二限位件4221靠近电池10的一侧的托盘41，此时，第二限位件4221在朝向电池10的方向移动的过程中，第二弹性件4222产生压缩形变。
第二弹性件4222可以是弹簧、橡胶等结构，这里不做限制。
可以理解的是，设置第二限位机构422包括第二弹性件4222和第二限位件4221，通过第二弹性件4222储存的弹性势能实现第二限位件4221的回位，而无需设置专门的回位驱动机构，简化了电池定位装置40的整体结构。
·件4211的直线运动，如此，有利于提高第一限位件4211的运动稳定性，便于控制第一限位件4211对电池10的第一夹持面10a的夹持力，降低第一限位件4211对电池10造成较大冲击载荷的可能性。
在丝杠42122运动到位后，要想保持第一限位机构421对第一夹持面10a的夹持力，则需要避免丝杠42122在动反转而不能对第一夹持面10a形成有效夹持力的现象。可以设置单独的锁定机构，以防止丝杠42122不必要的反转或者打滑等现象。
在一些可选的实施例中，丝杠42122的螺纹升角小于静摩擦角。
则第一限位机构421朝向电池10的方向运动到位后，无需对丝杠42122设置锁定装置，即可实现丝杠42122的自锁，降低丝杠42122自动反转而无法对第一夹持面10a形成有效夹持力的可能性。
在一些实施例中，如图11所示，托盘41包括设置于托盘41的边缘的活动支撑件411，活动支撑件411至少能够沿第一方向X移动，以让出活动支撑件411沿垂直于第一方向X与电池10相对的空间。
可以理解的是，在对电池10进行捆扎的过程中，捆扎装置往往需要与电池10紧贴才能进行。而对于不同的电池10，其尺寸往往不同，特别是电池10在垂直于第一方向X的尺寸，如果电池10的尺寸较小，则电池10放置在托盘41上时，由由于托盘41的阻挡，无法实现捆扎装置对电池10的捆扎。而设置托盘41包括设置于托盘41的边缘的活动支撑件411，则在电池10的尺寸较小时，通过活动支撑件411沿第一方向X的移动，以让出活动支撑件411沿垂直于第一方向X与电池10相对的空间，便于对电池10的捆扎工艺的顺利进行。而当电池10的尺寸较大，需要活动支撑件411的支撑时，则可以利用活动支撑件411对电池10进行正常的承载。
因此，通过设置活动支撑件411，可以提高电池定位装置40对不同尺寸电池10的适用性，提高电池定位装置40的设备利用率。
活动支撑件411可以一个整体，也可以包括多段子段，这里不做限制。活动支撑件411沿第一方向X的运动，可以通过人工的方式实现，也可以通过设置对应的驱动机构实现。
在一些实施例中，活动支撑件411包括沿第一方向X设置的两个支撑子段4111。电池定位装置40包括与支撑子段4111连接的打开机构，打开机构用于驱动两个支撑子段4111沿第一方向X相向或者相背移动。
具体地，当电池10的尺寸较小时，设置打开机构使两个支撑子段4111沿相背的方向移动，以让出活动支撑件411沿垂直于第一方向X与电池10相对的空间。而当电池10的尺寸较大时，则控制打开机构驱动两个支撑子段4111沿相对的方向移动，以对电池10进行支撑。
因此，设置活动支撑件411包括两个支撑子段4111，并设置打开 机构控制两个支撑子段4111的相对或者相背运动，便于操作人员操作。
在一些实施例中，电池定位装置40还包括整形加压机构。整形加压机构用于沿第三方向Z夹持电池10，第三方向Z垂直于第一方向X以及垂直于第二方向Y。其中，电池10沿第二方向Y放置于托盘41。
由于限位机构42沿第一方向X对电池10进行夹持，因此，限位机构42沿第一方向X对电池10进行整形。然后，在一些实施例中，电池10沿第三方向Z也需要整形，以使电池10内部的零部件之间眼第三方向Z的端面排列整齐。
因此设置整形加压机构可以对电池10内部的零部件沿第三方向Z进行整形，进一步降低形成的电池10发生错位的风险，提高电池10的结构稳定性。

本申请实施例提供的电池困扎方法，由于采用了上述任意一实施例提供的电池定位装置40，可以对电池10的第一夹持面10a和第二夹持面10b分开泄压，便于采用机器对电池10进行捆扎，如此，有利于提高电池10的捆扎效率，且捆扎后形成的电池10内部零部件发生错位的风险较低，有利于提高电池10的结构稳定性和后续的工作安全性。
在一些可选的实施例中，如图13所示，电池10的定位方法还包括：
S40、围绕电池10设置第一绑带，第一绑带经过第一夹持面10a。

S30、操作限位机构42，以松开第一夹持面10a的步骤，包括：
S31、操作第一限位机构421移动，以使第一限位机构421松开第一夹持面10a。如此，可以实现对第一夹持面10a的泄压，而保持第二限位机构422对第二夹持面10b的夹持作用，便于后续对电池10捆扎第一绑带。
在一些实施例中，电池定位装置40还包括锁止机构43，锁止机构43用于锁止第二限位机构422，以使第二限位机构422保持夹持第二夹持面10b的状态。S31、操作第一限位机构421移动，以使第一限位机构421松开第一夹持面10a的步骤之前，如图15所示，电池困扎方法还包括：
S50、操作锁止机构43，以锁止第二限位机构422。
通过锁止机构43锁止第二限位机构422，有利于保持第二限位机构422对第二夹持面10b的夹持作用。
