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。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。
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。箱体可以降低液体或其他异物影响电池单体的充电或放电的风险。
电池单体包括端盖组件、壳体、电极组件和绝缘件,电极组件由正极片、负极片和隔离膜组成。电池单体主要依靠金属离子在正极片和负极片之间移动来工作。正极片包括正极集流体和正极活性物质层,正极活性物质层涂覆于正极集流体的表面,未涂敷正极活性物质层的正极集流体凸出于已涂覆正极活性物质层的正极集流体,未涂敷正极活性物质层的正极集流体作为正极耳。以锂离子电池为例,正极集流体的材料可以为铝,正极活性物质可以为钴酸锂、磷酸铁锂、三元锂或锰酸锂等。负极片包括负极集流体和负极活性物质层,负极活性物质层涂覆于负极集流体的表面,未涂敷负极活性物质层的负极集流体凸出于已涂覆负极活性物质层的负极集流体,未涂敷负极活性物质层的负极集流体作为负极耳。负极集流体的材料可以为铜,负极活性物质可以为碳或硅等。为了保证通过大电流而不发生熔断,正极耳的数量为多个且层叠在一起,负极耳的数量为多个且层叠在一起。隔离膜的材质可以为PP(polypropylene,聚丙烯)或PE(polyethylene,聚乙烯)等。此外,电极组件可以是卷绕式结构,也可以是叠片式结构,本申请实施例并不限于此。
壳体具有开口,端盖组件用于封盖壳体的开口,壳体和端盖组件共同形成容纳电极组件和绝缘件的容纳空间。绝缘件包裹于电极组件的外周并与端盖组件连接,绝缘件可以绝缘隔离电极组件和壳体。端盖组件和绝缘件可以是熔接、粘接等。绝缘件在与端盖组件连接之前需要进行定位,才能使得绝缘件与端盖组件连接时具有较为准确的相对的位置关系,比如绝缘件的边缘和端盖组件的边缘之间的距离需要控制在预设范围内,才能使得绝缘件和端盖组件之间具有较好的位置关系便于连接,从而形成高质量的连接关系。但是相关技术中电池单体的制造设备通过定位销与绝缘件上的定位孔配合定位绝缘件,定位销插设于定位孔内后,由于定位孔和定位销之间间隙配合,绝缘件能够沿定位孔的任意径向偏移,降低了绝缘件的定位精度,从而导致绝缘件和端盖组件之间不能形成较合理的相对位置关系,从而导致绝缘件和端盖组件的连接质量降低。
基于上述考虑,为了缓解因电池单体的制造设备对绝缘件定位精度低,而导致绝缘件和端盖组件的连接 质量较低的问题,本申请实施例提供一种定位装置,定位装置包括定位平台和定位机构,定位平台用于支撑绝缘件,定位机构被配置为抵靠绝缘件的至少一个边缘,以定位绝缘件。
通过定位机构抵靠绝缘件的至少一个边缘,以定位绝缘件,能够提高定位精度,从而使得绝缘件转移至下一个工位与其他部件配合时,绝缘件和其他部件有较好的相对位置关系,从而有利于提高其他部件和绝缘件的连接质量。
本申请实施例公开的定位装置可以但不限用于定位绝缘件,还可用用于电池单体的制造设备,以生产电池单体。
以下实施例为了方便说明,以定位机构用于制造电池单体为例对相关结构进行说明。
本申请实施例提供一种电池单体的制造设备,电池单体的制造设备包括定位装置和夹持机构(图中未示出),夹持机构设置于定位装置的下游,夹持机构用于夹持定位于定位装置上的绝缘件。
需要说明的是,本申请实施例中所提及的“下游”指的是生产顺序的先后,下游是指生产顺序在后,并非限定各部件之间的空间位置。可以理解的,夹持机构设置于定位装置的下游是指绝缘件先通过定位装置完成定位后,再通过夹持机构夹持至下一个工位。
如图1、图2所示,在一些实施例中,定位装置100用于定位绝缘件200(图6中示出),绝缘件200用于包裹工件的外表面,定位装置100包括定位平台10和定位机构20,定位平台10用于支撑绝缘件200,定位机构20被配置为抵靠绝缘件200的至少一个边缘,以定位绝缘件200。
根据定位装置100应用的场景不同,工件可以有所不同,示例性地,工件可以是指电极组件,绝缘件200包裹于电极组件的外表面,以使绝缘隔离电极组件和壳体,绝缘件200在与端盖组件连接。再比如,工件可以是外壳,绝缘件200包裹于壳体的外表面。当定位装置100用于制造电池时,工件也可以是电池的箱体,绝缘件200包裹于箱体的外表面。
定位平台10用于支撑绝缘件200可以是定位平台10承载绝缘的部分或者全部重力。定位平台10具有支撑面11,支撑面11用于放置绝缘件200,以使定位平台10支撑绝缘件200。
定位机构20用于与绝缘件200的至少一个边缘抵靠,从而通过对绝缘件200的边缘定位,以使被定位装置100定位的绝缘件200通过夹持机构夹持至下一个工位后,绝缘件200与位于下一个工位的其他部件有较好的配合关系。示例性地,在绝缘件200包裹于电极组件的外表面,则被定位装置100定位的绝缘件200被夹持机构转移至下一个工位后,在下一个工位绝缘件200包裹于电极组件的外表面,并与端盖组件连接。因此,通过定位机构20抵靠绝缘件200的至少一个边缘能够使得绝缘件200被转移至下一个工位后和端盖组件形成合理的位置关系,便于端盖组件和绝缘件200连接,有利于提高端盖组件和绝缘件200的连接质量。
通过定位机构20抵靠绝缘件200的至少一个边缘,以定位绝缘件200,能够提高定位精度,从而使得绝缘件200转移至下一个工位与其他部件配合时,绝缘件200和其他部件有较好的相对位置关系,从而有利于提高其他部件和绝缘件200的连接质量。
其中,定位机构20可以是抵靠绝缘件200的一个边缘,以定位绝缘件200。在另一些实施中,定位机构20也可以抵靠绝缘件200的多个边缘,以定位绝缘件200,以使绝缘件200的多个边缘均具有较好的定位精度,从而使得绝缘件200转移至下一个工位与其他部件配合时,绝缘件200和其他部件有较好的相对位置关系,从而有利于提高其他部件和绝缘件200的连接质量。多个是指两个及两个以上。
在一些实施例中,定位机构20被配置为抵靠绝缘件200相对的两个边缘,以定位绝缘件200。
通过定位机构20抵靠绝缘件200的相对的两个边缘,以定位绝缘件200,能够提高定位精度,从而使得绝缘件200转移至下一个工位与其他部件配合时,绝缘件200和其他部件有较好的相对位置关系,从而有利于提高其他部件和绝缘件200的连接质量。
如图2、图3、图4所示,在一些实施例中,定位机构20包括第一抵靠部21、第二抵靠部22和调节组件23,第一抵靠部21和第二抵靠部22沿第一方向Y相对设置,第一抵靠部21和第二抵靠部22被配置为分别抵靠绝缘件200相对的两个边缘,第一抵靠部21和第二抵靠部22连接调节组件23,调节组件23被配置为调节第一抵靠部21和第二抵靠部22之间的距离。
调节组件23用于调节第一抵靠部21和第二抵靠部22沿第一方向Y的距离。如图2所示,在一些实施例中,第一抵靠部21和第二抵靠部22分别位于定位平台10沿第一方向Y相对的两侧,沿垂直支撑面的方向X观察,第一抵靠部21和第二抵靠部22不重叠。在另一些实施例中,沿垂直支撑面的方向X观察,第一抵靠部21可以与定位平台10重叠,第二抵靠部22可以与定位平台10重叠。
其中,调节组件23可以通过驱动第一抵靠部21和第二抵靠部22中的一者在第一方向Y上沿靠近或者远离另一者的方向移动,从而调节第一抵靠部21和第二抵靠部22沿第一方向Y的距离。调节组件23也可以驱动第一抵靠部21和第二抵靠部22两者在第一方向Y上相互靠近或相互远离,从而调节第一抵靠部21和第二抵靠部22之间的距离。
在调节组件23驱动第一抵靠部21和第二抵靠部22两者在第一方向Y相互靠近或者远离的实施例中,可以通过一个调节组件23同步驱动第一抵靠部21和第二抵靠部22相互靠近或远离,能够简化定位机构20的结构,降低制造成本。也可以通过两个调节组件23分别驱动第一抵靠部21和第二抵靠部22沿第一方向Y移动,以使第一抵靠部21和第二抵靠部22相互靠近或远离,这样能够独立控制第一抵靠部21和第二抵靠部22的运动,使得定位机构20的定位方式更加灵活。
第一抵靠部21具有面向第二抵靠部22的第一抵靠面211,第二抵靠部22具有面向第一抵靠部21的第二抵靠面221。定义绝缘件200沿第一方向Y的两个边缘分别为第一边缘210(图6中示出)和第二边缘220(图6中示出)。第一抵靠面211用于与第一边缘210相抵靠,第二抵靠面221用于与第二边缘220相抵靠。在第一抵靠面 211与第一边缘210相抵且第一抵靠面211与第一边缘210平行、以及第二抵靠面221与第二边缘220相抵且第二抵靠面221与第二边缘220平行的情况下,可认为定位机构20完成对绝缘件200定位。在第一抵靠部21和第二抵靠部22分别设置于定位平台10相对的两侧的实施例中,第一抵靠部21和第二抵靠部22分别与绝缘件200相对的两个边缘相抵时,第一抵靠部21可以与定位平台10的边缘相抵,第一抵靠部21也可以与定位平台10的边缘存在距离,第二抵靠部22可以与定位平台10的边缘相抵,第二抵靠部22也可以与定位平台10的边缘存在距离。
需要说明的是,定位机构20对绝缘件200定位可以是在第一抵靠部21和第二抵靠部22之间的距离调整完成后,将绝缘件200放置于第一抵靠部21和第二抵靠部22之间,并调整至第一抵靠面211与第一边缘210相抵靠且第一抵靠面211平行第一边缘210,以及调整至第二抵靠面221与第二边缘220相抵靠且第二抵靠面221平行第二边缘220。
定位机构20对绝缘件200定位也可以是先将待定位的绝缘件200放置在定位平台10,沿第一方向Y,绝缘件200放置于第一抵靠部21和第二抵靠部22之间,调节组件23调节第一抵靠部21和第二抵靠部22之间的距离,使得第一抵靠部21第二抵靠部22之间的距离逐渐减小,在调节过程中,第一抵靠面211逐渐靠近第一边缘210,第二抵靠面221逐渐靠近第二边缘220,直至第一抵靠面211与第一边缘210抵靠且平行以及第二抵靠面221与第二边缘220且平行,这一过程中第一抵靠部21和第二抵靠部22不断调整绝缘件200的位置,直至第一抵靠面211与第一边缘210抵靠且平行以及第二抵靠面221与第二边缘220且平行,完成对绝缘件200的定位。
通过第一抵靠部21和第二抵靠部22分别抵靠绝缘件200的相对的两个边缘,能够提高定位精度,调节组件23能够调节第一抵靠部21和第二抵靠部22之间的距离,以使定位机构20能够对不同尺寸的绝缘件200进行定位,适用范围更广。
请继续参照图2、图3、图4,在一些实施例中,调节组件23包括第一连接座231、第二连接座232和驱动件233,第一连接座231连接第一抵靠部21和驱动件233,第二连接座232连接第二抵靠部22和驱动件233,驱动件233被配置驱动第一连接座231和第二连接座232中的至少一者沿第一方向Y移动,以调节第一抵靠部21和第二抵靠部22之间的距离。
第一抵靠部21和驱动件233通过第一连接座231间接连接,第二抵靠部22和驱动件233通过第二连接座232间接连接。调节组件23可以包括一个驱动件233,第一连接座231和第二连接座232均与该驱动件233连接,该驱动件233同步驱动第一连接座231和第二连接座232,能够简化调节组件23的结构,从而简化定位机构20的结构,降低制造成本。调节组件23可以包括两个驱动件233,两个驱动件233分别第一连接座231和第二连接座232,两个驱动件233分别驱动第一连接座231和第二连接座232,这样能够独立控制第一连接座231和第二连接座232的运动,从而独立控制第一抵靠部21和第二抵靠部22的运动,使得定位机构20的定位方式更加灵活。
第一连接座231和第二连接座232的结构有多种,如图3、图4所示,第一连接座231和第二连接座232均为沿第一方向Y延伸的杆状结构。在另一些实施例中,第一连接座231和第二连接座232也可以呈L型。第一连接座231和第二连接座232的结构可以相同也可以不同。
第一连接座231和第二连接座232的设置便于驱动件233的动力传递至第一抵靠部21和第二抵靠部22以调节第一抵靠部21和第二抵靠部22之间的距离。
在另一些实施例中,调节组件23也可以不设置第一连接座231和第二连接座232,第一抵靠部21和第二抵靠部22均与驱动件233之间连接。

第一连接座231和第二连接座232分别连接于驱动件233的第一输出端和第二输出端,驱动件233能够同步驱动第一连接座231和第二连接座232。
第一输出端和第二输出端的布置方式有多种,比如第一输出端和第二输出端沿第一方向Y相对布置、第一输出端和第二输出端在第一方向Y上重叠等。
驱动件233驱动第一连接座231和第二连接座232沿相反的方向移动,能够提高调节第一抵靠部21和第二抵靠部22之间的距离的效率。
在一些实施例中,驱动件233为双向气缸。
双向气缸具有沿第一方向Y相对布置两个活塞杆,两个活塞杆分别形成驱动件233的第一输出端和第二输出端。
双向气缸具有两个输出端,能够同步驱动第一连接座231和第二连接座232,驱动效率较高。
在另一些实施例中,驱动件233也可以是单向气缸、丝杆电机等。
如图2所示,在一些实施例中,定位平台10具有支撑面11,支撑面11用于支撑绝缘件200;第一连接座231和第二连接座232均位于定位平台10背离支撑面11的一侧。
在第一抵靠部21和第二抵靠部22之间距离最近时,沿垂直支撑面的方向X观察,第一连接座231和定位平台10重叠,第二支撑座和定位平台10重叠。在第一抵靠部21和第二抵靠部22之间距离最远时,沿垂直支撑面的方向X观察,第一连接座231和定位平台10可以重叠,也可以不重叠,第二支撑座和定位平台10可以重叠,也可以不重叠。
第一连接座231和第二连接座232均位于定位平台10背离支撑面11的一侧,降低调节组件23与绝缘件200干涉的风险,有利于提高定位精度。
在一些实施例中,驱动件233也位于定位平台10背离支撑面11的一侧,以便于驱动第一连接座231和第二连接座232,以及降低与绝缘件200干涉的风险,有利于提高定位精度。
如图3、图4所示,在一些实施例中,第一抵靠部21沿第一方向Y位置可调地设置于第一连接座231;和/或第二抵靠部22沿第一方向Y位置可调地设置于第二连接座232。
第一抵靠部21可以沿第一方向Y在第一连接座231上移动,以调节第一抵靠部21在第一连接座231上的位置。第二连接部可以沿第一方向Y在第二连接座232上的移动,以使调节第二抵靠部22在第二连接座232上的位置。

第一抵靠部21沿第一方向Y位置可调地设置于第一连接座231;和/或第二抵靠部22沿第一方向Y位置可调地设置于第二连接座232,能够增大第一抵靠部21和第二抵靠部22之间距离的调节范围,从而使得定位机构20能够对更多不同尺寸的绝缘件200进行定位,使得定位装置100的通用性更强。
实现第一抵靠部21沿第一方向Y位置可调地设置于第一连接座231和第二抵靠部22沿第一方向Y位置可调地设置于第二连接座232的方式有多种。

通过定位机构20抵靠绝缘件200的至少一个边缘,以定位绝缘件200,能够提高定位精度,从而使得绝缘件200转移至下一个工位与其他部件配合时,绝缘件200和其他部件具有较好的相对位置关系,从而有利于提高其他部件和绝缘件200的连接质量。
在一些实施例中,在将绝缘件200放置于定位平台10之前,绝缘件200的定位方法还包括:
S300,通过纠偏机构40旋转定位平台10和定位机构20,以调节定位平台10和定位机构20两者与供料装置之间的相对位置,供料装置用于提供绝缘件200。
供料装置是用于提供绝缘件200的装置。在一些实施例中,供料装置可以包括供料舱,供料舱内储存有绝缘件200。
由于设备的组装误差、设备频繁使用导致的误差等原因,可能使得定位平台10和定位机构20两者相对供料装置偏转一定的角度,这种偏转误差可能导致绝缘件200向定位平台10放置的过程中误差过大,绝缘件200不能放置于定位平台10或者即使绝缘件200放置于定位平台10后,定位机构20不能纠正该误差。
因此,在将绝缘件200放置于定位平台10之前,通过纠偏机构40旋转定位平台10和定位机构20,以调节定位平台10和定位机构20两者与供料装置之间的相对位置,使得供料装置提供绝缘件200能够较为准确地放置在定位平台10上。
在一些实施例中,通过将绝缘件200放置于定位平台10包括:
通过转移机构将供料装置提供的绝缘件200放置于定位平台10。
转移机构可以是机械手、传输带等。
通过转移机构将供料装置提供的绝缘件200放置于定位平台10,能够节约人力成本,提高生产效率。
在一些实施例中,在通过定位机构20抵靠绝缘件200的至少一个边缘之后,绝缘件200的定位方法还包括:
S400,通过纠偏机构40旋转定位平台10和定位机构20,以调节定位平台10和定位机构20两者与组装装置之间的相对位置,组装装置用于将绝缘件200与工件组装。
组装装置位于定位装置100的下游,为绝缘件200提供了下一个工位。示例性地,在制造电池单体的过程中,组装装置可以是将绝缘件200包裹于电极组件的外表面的工位,也可以是绝缘件200和端盖组件熔接的工位。
由于设备的组装误差、设备频繁使用导致的误差等原因,可能使得定位平台10和定位机构20两者相对组装装置偏转一定的角度,这种偏转误差可能导致绝缘件200不能转移至组装装置或者绝缘件200转移至组装装置后与工件之间仍有较大误差。
因此,在通过定位机构20抵靠绝缘件200的至少一个边缘之后,通过纠偏机构40旋转定位平台10和定位机构20,以调节定位平台10和定位机构20两者与组装装置之间的相对位置,以使绝缘件200转移至下一个工位与其他部件配合时,绝缘件200和其他部件具有较好的相对位置关系,从而有利于提高其他部件和绝缘件200的连接质量。
在一些实施例中,在通过定位机构20抵靠所述绝缘件200的至少一个边缘之后,绝缘件200的定位方法还包括:
通过夹持机构将所述定位平台10上的绝缘件200转移至组装装置,组装装置用于将绝缘件200与工件组装。
通过夹持机构将定位平台10上的绝缘件200转移至组装装置,能够节约人力成本,提高生产效率。
