目前，从市场形势的发展来看，电池的应用越加广泛。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。随着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。
本发明人注意到，在对生产电池的物料的组装过程中容易出现焊接不良的现象，焊接不良例如为虚焊，从而增加生产和制造成本。同时，一旦焊接不良的产品流入市场，会导致安全事故。以物料为电池单体为例，具体的表现为，在对电池的电池单体进行制造的过程中，需要将电池单体的端盖、电极组件和壳体组装在一起。具体地，需要将端盖与电极组件的壳体焊接在一起。但端盖、电极组件和壳体是不同的产线生产的组件，所以在焊接之前，必须对端盖、电极组件和壳体进行清洁，以避免在组装的过程中由于上述组件表面的脏污而引起的不良。
为了避免焊接不良的问题，发明人研究发现，可以在焊接前，使用毛刷等清洁工具对电极组件、壳体和端盖的表面进行物理清洁。例如，在电极组件装入壳体之前使用毛刷等清洁工具对电极组件的表面、壳体的表面和端盖的上表面进行物理清洁。然而，该方式只能在电极组件装入壳体以及端盖封盖壳体之前对电极组件、壳体和端盖进行单独清洁，并不能有效地清除电极组件在装入壳体时的刮蹭和壳体、端盖焊接之间的制程中所带来的污染。另外，毛刷等清洁工具只能进行简单的物理清洗，并不能有效地清除粘结胶和油渍等附着力强的污染物，未能彻底地解决因污染而产生的壳体、端盖的焊接不良问题。
基于以上考虑，为了解决电极组件的壳体和端盖焊接不良的问题，发明人经过深入研究，设计了一种清洁装置，在电极组件的壳体和端盖在部分盖合的情况下，运用激光对的壳体和端盖的待焊接位置及附近区域进行清洁，使得电极组件的壳体和端盖焊接区域在制程中沾染的脏污能够被快速高效地清洁，从而有效地解决电极组件的壳体和端盖焊接不良。
请参阅图1和图2，图1为本申请一些实施例的清洁装置100的结构示意图，图2为本申请一些实施例的清洁装置100的结构示意图。本申请实施例公开的清洁装置100可以用于电池(如图27)的生产和制造。该清洁装置100也可以用于其他相似结构的生产和制造，例如，消费类电子产品的生产和制造、家用电器的生产和制造、钟表产品的生产和制造等。
根据本申请的一些实施例，提供了一种用于清洁物料200的清洁装置100，物料200包括壳体210和端盖220(如图8所示)。清洁装置100包括第一固定件10、第二固定件20和激光组件30。第一固定件10用于固定壳体210；第二固定件20与第一固定件10相对设置并用于固定端盖220；激光组件30设置在第一固定件10和第二固定件20的一侧，用于在端盖220部分合入壳体210时清洁壳体210和端盖220。
具体地，清洁装置100为使用激光组件30作为清洁工具的装置，清洁装置100可以对被清洁的物体进行全方位地清洗。物料200例如可以为电池单体、电池包，本申请不限定物料200的具体类型。物料200可以包括有端盖220、壳体210、电极组件230(如图12)以及其他的功能性部件。物料200可呈圆柱体、扁平体、长方体或其它形状等，即物料200的端盖220和壳体210组装后可呈圆柱体、扁平体、长方体或其它形状等。
端盖220是指盖合于壳体210的开口处以将物料200的内部环境隔绝于外部环境的部件。不限地，端盖220的形状可以与壳体210的形状相适应以配合壳体210。可选地，端盖220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220在受挤压碰撞时就不易发生形变，使物料200能够具备更高的结构强度，安全性能也可以有所提高。端盖220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。
壳体210是用于配合端盖220以形成物料200的内部环境的组件，其中，形成的内部环境可以用于容纳电极组件230以及其他部件。壳体210和端盖220可以是独立的部件，可以于壳体 210上设置开口，通过在开口处使端盖220盖合开口以形成物料200的内部环境。壳体210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。具体地，壳体210的形状可以根据电极组件230的具体形状和尺寸大小来确定。壳体210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。

激光组件30可以包括任意型号的激光器，激光器可以是市场上现有的，或者定制的，本申请对此不做限定。激光组件30可以设置在第一固定件10和第二固定件20的一侧以避免与第一固定件10和第二固定件20发生干涉，并有利于对壳体210和端盖220进行清洗，进一步地，在焊接之前，激光组件30可以对壳体210和端盖220的焊接区域进行彻底清洁，包括但不限于该区域的油渍、灰尘以及粘结胶等。
端盖220完全合入壳体210发生在端盖220与壳体210经过激光清洁后，端盖220被推入壳体210并抵持在壳体210的开口处的状态，“部分合入”是指端盖220尚未完全合入壳体210，而是在端盖220被推入壳体210的某一时刻的状态。
本申请实施例的清洁装置100中，通过第一固定件10固定物料200的壳体210，并用第二固定件20固定端盖220，同时，将激光组件30设置在第一固定件10和第二固定件20的一侧。这样的设计可以对物料200进行焊接前的清洁，能够有效地避免壳体210和端盖220组装过程中产生的脏污进入壳体210内部，以及能够有效地避免激光清洁过程中产生的粉尘进入物料200的内部，从而有效地解决壳体210和端盖220焊接中的污染性缺陷，进而提高壳体210和端盖220焊接的良率。
根据本申请的一些实施例，可选地，请继续参考图1和图4，图4为本申请一些实施例的壳体210被夹持于夹持件11上的结构示意图。第一固定件10包括多个夹持件11，多个夹持件11共同夹持壳体210。
具体地，多个夹持件11可以用于夹持各种形状的壳体210，多个夹持件11可以稳定地使壳体210固定于夹持件11之间。进一步地，多个夹持件11可以夹持壳体210的外表面，夹持件11上可以设置有海绵等增加摩擦力的材料，或者增加夹持件11与壳体210连接处的粗糙度，以使夹持件11与壳体210之间不发生任意方向位移或者翻转。
如此，通过设置夹持件11，可以使得壳体210在被清洁时能够被平稳地移动。
当然，在其他实施方式中，第一固定件10可以通过吸附等方式固定壳体210，本申请不限制第一固定件10固定壳体210的方式。
根据本申请的一些实施例，可选地，请继续参阅图1和图4，图4为本申请一些实施例的壳体210被夹持于夹持件11上的结构示意图。多个夹持件11沿多个夹持件11沿壳体210的周向排布。
壳体210的周向可以是环绕壳体210的长度中心轴线的方向，在壳体210的周向上，壳体210轮廓上面积大，易被夹持件11夹持而不发生晃动。多个夹持件11可以沿壳体210的周向任意按照任意间距排布，也可以按照固定的间距排布，当多个夹持件11沿壳体210的周向按照固定间距排布时，可以利用最少数量的夹持件11使得壳体210被稳定地夹持，以节约生产和制造成本。
如此，多个夹持件11排布在壳体210的周向时，壳体210的被夹持面积更大，壳体210可以被夹持的更加稳定，从而有利于后续装配。

如此，夹持驱动部件40可以控制夹持件11夹持不同轮廓形状的壳体210，使得夹持件11的设计具有通用性。

不限地，第一吸附件22可以是多种结构形式的元件，例如，第一吸附件22可以是利用气体吸附的原件、利用磁力吸附的原件等。
可选地，第一安装件21能在清洁完成后推动端盖220与壳体210完全扣合。
当然，在其他实施方式中，第二固定件20可以通过夹持等方式固定端盖220。
如此，端盖220可以被吸附于第一吸附件22上，使得端盖220可以被稳定地固定，从而保证清洁的效果。
根据本申请的一些实施例，可选地，请继续参阅图1和图6，清洁装置100还包括设置在第一安装件21上的保护壳50，第一吸附件22位于保护壳50中，保护壳50用于罩住端盖220的至少部分外表面。

如此，转动驱动部件60可以使得端盖220和壳体210可以被全方位地清洁。
根据本申请的一些实施例，可选地，请继续参阅图7和图6，图7为本申请一些实施例的清洁装置100的部分结构拆解示意图。转动驱动部件60包括第一驱动子件61和第二驱动子件62，第一驱动子件61用于驱动第一固定件10转动，第二驱动子件62用于驱动第二固定件20转动。

第一驱动子件61和第二驱动子件62例如包括电机的零部件，或者说，第一固定件10和第二固定件20可以通过电机驱动而转动。
如此，第一驱动子件61和第二驱动子件62可以分别驱动第一固定件10和第二固定件20转动，有利于第一固件10和第二固定件20的转动控制，实现对壳体210和端盖220的全方位清洁。

如此，通过使第一固定件10和第二固定件20，可以使得壳体210和端盖220在被清洁时不会发生变形，并且第一固定件10和第二固定件20可以同步被清洗，提高清洗效率。

如此，壳体210和端盖220同步转动可以避免壳体210和端盖220组装后发生相对位移而被损坏，利用激光清洁壳体210和端盖220可以清洁壳体210和端盖220表面附着力较强的脏污，使得清洁的效果更好。
根据本申请的一些实施例，可选地，请继续参阅图3、图6、图10和图23，图23为本申请一些实施例的流程示意图。清洁方法还包括：
S60，通过端盖220的注液口221向壳体210内通入气体。
具体地，第一气压部件104可以通过端盖220的注液口221向壳体210内通入气体。
如此，通过向壳体210内部通入气体，可以使得壳体210内形成正压，从而使得壳体210内部压力比外部的压力大，从而有效地防止在激光清洁的过程中产生的或从壳体210和端盖220表面清洁出来的脏污进入壳体210内部，进而避免物料200的安全隐患。
根据本申请的一些实施例，可选地，请继续参阅图8、图6、图11和图24，图24为本申请 一些实施例的流程示意图。清洁方法还包括：
S70，在清洁壳体210和端盖220时，吸收壳体210和端盖220周围的污染物。
具体地，在清洁壳体210和端盖220时，第一气压部件104和第二气压部件105可以吸收壳体210周围的污染物。
如此，吸收壳体210周围的污染物可以防止清洁过程中或者清洁完毕后脏污在外部环境的带动下到达焊接区域，从而造成焊接不良。
根据本申请的一些实施例，可选地，请继续参阅图3、图8、图25和图26，图25为本申请一些实施例的状态过程示意图，图26为本申请一些实施例的流程示意图。清洁方法还包括：
S80，在清洁壳体210和端盖220后，将端盖220完全合入壳体210。
具体地，在清洁壳体210和端盖220后，合盖驱动部件110可以将端盖220完全合入壳体210。
如此，端盖220可以在被清洁过后完全合入壳体210中，以便后续能够对端盖220和壳体210的连接部位进行焊接。
根据本申请的一些实施例，可选地，请继续参阅图27，图27为本申请一些实施例的电池400的结构示意图。本申请还提供了一种电池400，该电池400采用上述清洁方法制造得到。所述电池400可以为电池单体，也可以为电池包等具有壳体210和端盖220的产品。
