技术领域
本申请涉及电池技术领域，尤其是涉及一种电池的定位装置及制造设备。
背景技术
电池在加工过程中，当电池处于静置加压加热工位进行侧板与电芯之间胶固化时，缺乏对侧板轮廓度的定位管控，导致电池成型后侧面轮廓度无法满足要求。
发明内容
本申请旨在至少解决现有技术中存在的技术问题之一。为此，本申请的一个目的在于提出一种电池的定位装置，可以缓解电池的侧面轮廓无法控制的问题。
根据本申请第一方面实施例的电池的定位装置，包括：位于第一方向两侧并形成有定位空间的侧板定位组件，所述定位空间具有与所述第一方向正交的第二方向，所述侧板定位组件包括本体和设在所述本体上的多个定位部，多个所述定位部沿所述第一方向间隔开设置，且至少部分可沿所述第二方向移动。
根据本申请实施例的电池的定位装置，通过设置位于第一方向两侧并形成有定位空间的侧板定位组件，定位空间具有与第一方向正交的第二方向，侧板定位组件包括本体和设在本体上的多个定位部，多个定位部沿第一方向间隔开设置，且至少部分可沿第二方向移动，可以对电池的侧板定位进行精准控制，能更好地控制电池的侧面轮廓度。
在本申请的一些实施例中，所述本体为加热部件。通过这种方式本体在起到支撑作用的同时还能配备加热功能，在静置工位既能对电池加压定位，还能提供热源，对侧板进行加热。例如，本体为条形加热块，多个定位部设在条形加热块上。
在本申请的一些实施例中，所述定位部包括彼此相连的第一部分和第二部分，所述第一部分设在所述加热部件内。也就是说，定位部的部分嵌设在加热部件内，这样可以提高定位部和加热部件的结合度，定位部不易发生松动或脱落，使定位部具备更稳定的 定位效果。
在本申请的一些实施例中，所述加热部件的内侧面上设有安装槽，所述第一部分设在所述安装槽内。通过这种方式定位部能在加热部件上进行拆卸或安装，可以更换定位部，这样就能不用因某个部件受损而更换一整套侧板定位组件，可以降低使用成本。
在本申请的一些实施例中，所述加热部件上设有第一过孔，所述定位部穿设在所述第一过孔内，且部分凸出所述加热部件的内侧面。通过这种方式定位部能完全穿过加热部件，与加热部件的结合面更大，从而在加热部件上具有更好的固定效果。
在本申请的一些实施例中，所述定位装置还包括：加热部件，所述加热部件设在所述本体上。加热部件和定位部是两个相互独立的部件。
在本申请的一些实施例中，所述加热部件包括加热主体和设在所述加热主体上的柔性导热部，所述柔性导热部设在所述加热主体的靠近所述定位空间的一端上。由于柔性导热部具备一定的压缩量，可以更好地贴合在侧板上，结合更紧密，从而以更好地传递加热主体上的热量，使侧板上各处均能受热，同时也使胶固化效果更好。
在本申请的一些实施例中，所述柔性导热部具有靠近所述定位空间设置的接触面，所述定位部具有靠近所述定位空间设置的定位面，所述接触面的面积大于多个所述定位面的面积之和。这样在起到定位作用的同时，较大的接触面使得加热部件产生的热量可以更快地传递到侧板上，侧板被加热的速度更快，有利于提升胶固化效果。
在本申请的一些实施例中，所述定位部为刚性定位部。通过这种方式定位部能起到刚性定位支撑，有利于提升定位的精准性。
在本申请的一些实施例中，所述柔性导热部的围绕所述第二方向的周向边沿和所述加热主体的围绕所述第二方向的周向边沿保持平齐。通过这种方式柔性导热部和加热主体的形状保持一致，整体性更好，同时柔性导热部和加热主体一侧的表面积大小相等，可以快速传导加热主体产生的热量。
在本申请的一些实施例中，所述柔性导热部上设有第二过孔，所述定位部的靠近所述定位空间的部分设在所述第二过孔内。采用这种方式定位部和柔性导热部可以集中布置，第二过孔可以使柔性导热部不会影响定位部的定位，侧板定位组件的结构比较紧凑，可以节省空间。
在本申请的一些实施例中，所述定位部的位于所述第二过孔内的部分上形成有定位面，所述柔性导热部具有靠近所述定位空间设置的接触面，所述定位面与所述接触面之间形成有压缩间隙，所述压缩间隙小于1mm。压缩间隙小于1mm既可以使柔性导热部与侧板柔性接触，同时也使柔性导热部具备一定的刚性，可以对侧板起到支撑维稳作用。
在本申请的一些实施例中，所述定位部包括定位主体和多个层叠设置的垫片，多个所述垫片设在所述定位主体的远离所述柔性导热部的一端，多个所述垫片的数量可调。通过调整垫片的数量就能改变定位主体在加热部件的内侧面上的凸出长度，以适应调整侧板对柔性导热部的压缩量，另一方面，也能适应性地调整对不同电池的定位效果。
在本申请的一些实施例中，所述定位空间具有正交于所述第一方向和所述第二方向的第三方向，所述定位空间具有中心面，所述定位空间、所述加热主体、所述柔性导热部和所述定位部在所述第三方向上均关于所述中心面呈对称设置。通过这种方式使得加热主体、柔性导热部和定位部居中设置，可以作用在电池的侧板的中心位置，带来更好的定位和支撑效果。
在本申请的一些实施例中，所述定位空间具有正交于所述第一方向和所述第二方向的第三方向，所述定位空间具有中心面，所述定位空间、所述加热主体和所述柔性导热部在所述第三方向上均关于所述中心面呈对称设置，多个所述定位部在所述中心面的两侧依次交错布置。通过这种方式多个定位部在中心面的两侧依次交错布置，不仅能作用在电池的侧板的中心区域，同时也能增加与侧板的支撑面，定位和支撑效果更好。
根据本申请第二方面实施例的电池的制造设备，包括前文所述的电池的定位装置。通过该制造设备可以在制造过程中对电池的侧板进行精准定位，能更好地控制电池的侧面轮廓度。

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。
动力电池一般是指电池包或是指电池模组成组的电池包，而本申请中提到的“电池”可以是指电池模组或电池包，在电池的生产加工过程中，当电池输送至某一静置工位时需要对电池加压，本申请人注意到，在该工位时定位工装会对电池的两个端板进行加压定位，但缺乏对电池的侧板的压紧定位，这样就使得电池的侧板和电芯之间在胶固化时，电池的侧面的平整度无法保证，电池的侧面轮廓容易发生变形。
申请人研究发现，可以设计对电池的侧板进行加压定位的定位工装，通过定位工装就能对电池两侧的侧板加压定位，这样就使得胶固化过程中电池的侧面轮廓能得到管控，缓解电池的侧面轮廓发生变形。
下面参考图1-图8，描述根据本申请第一方面实施例的定位装置100。
如图1所示，根据本申请第一方面实施例的电池200的定位装置100，包括：位于第一方向两侧并形成有定位空间的侧板定位组件10，定位空间具有与第一方向正交的第二方向，侧板定位组件10包括本体和设在本体上的多个定位部101，多个定位部101沿第一方向间隔开设置，且至少部分可沿第二方向移动。
“第一方向”和“第二方向”是指相互垂直的两个方向，例如，第一方向可以是指图1的前后方向，第二方向可以是指图1的左右方向，第一方向和第二方向可以根据实际使用环境时可以具体设置，不限于此，这里不再赘述。
“定位空间”可以是指第一方向两侧的侧板定位组件10相互之间所限定的区域，参考前文所述，例如，当第一方向为图1的前后方向时，侧板定位组件10为至少两个，侧板定位组件10为两个时，分别设在左右两侧，左右两个侧板定位组件10限定出定位空间，定位空间可以用于放置电池200。侧板定位组件10也可以为其他数量，例如四个，其中，两个设置在左侧，其余两个设在右侧，侧板定位组件10的数量和布置方式根据需要可以具体设置，这里不再赘述。
在侧板定位组件10中，定位部101可以是指止抵在电池200的侧板210上的部件，例如，定位部101可以是指圆柱形的定位柱或方形的定位块，通过定位部101与侧板210接触起到定位作用。例如，侧板210的长度方向可以与第一方向保持同向，因此多个定位部101沿第一方向间隔开设置就能在多个定位点上对侧板210进行定位，由于胶固化过程中侧板210和电芯之间胶水的厚度可能存在偏差，使电池200的侧面所引起的形变量不同，所需施加的压力也可能不同，多个定位部101能对侧板210进行多点定位，可以起到精准定位的作用，提高电池200的侧面轮廓管控效果。其中，本体可以是指固定定位部101的支撑部件，例如，本体可以是固定座、安装板等。
为使电池200能放入到定位空间内，多个定位部101中至少部分可沿第二方向移动，第二方向可以是与电池200的宽度方向同向，这样就能调整定位空间在第二方向上的尺寸，有利于放入电池200，然后定位部101沿第二方向移动压紧在侧板210上完成定位。具体地，第一方向两侧的侧板定位组件10中，可以是一侧的多个定位部101沿第二方向移动，也可以是两侧的多个定位部101沿第二方向移动。
需要说明的是，定位装置100可以应用在电池200的制造设备中，例如，制造设备可以是指自动化生产线，定位装置100布置在生产线的特定工位上，用于对电池200进行定位压紧。此外，侧板定位组件10的本体可以连接有外部移动部件，外部移动部件可以是指气缸、电推杆或直线模组等，外部移动部件与第一方向两侧的本体相连，推动两侧的定位部101运动，从而止抵在电池200的侧板210上进行定位。
根据本申请实施例的电池的定位装置100，通过设置位于第一方向两侧并形成有定位空间的侧板定位组件10，定位空间具有与第一方向正交的第二方向，侧板定位组件10包括本体和设在本体上的多个定位部101，多个定位部101沿第一方向间隔开设置，且至少部分可沿第二方向移动，可以对电池200的侧板210定位进行精准控制，从而能更好地控制电池200的侧面轮廓度。
在本申请的一些实施例中，如图1、图2所示，本体为加热部件102。加热部件102可以是指能释放热源的部件，例如，电加热块、加热管、加热丝等。本体在起到支撑作用的同时还能具备加热功能，起到“一物两用”的作用，可以减少零件数量，简化装置结构。通过该方式使得在静置工位时既能对电池200加压定位，还能提供热源，对侧板210进行加热。
具体地，加热部件102可以为条形加热块，多个定位部101设在条形加热块上。
在本申请的一些实施例中，如图3所示，定位部101包括彼此相连的第一部分1011和第二部分1012，第一部分1011设在加热部件102内。第一部分1011可以是指位于加热部件102内的部分，第二部分1012可以是指凸出加热部件102表面的部分，其中，第二部分1012起到对侧板210的定位作用，第一部分1011安装在加热部件102内，即定位部101的部分嵌设在加热部件102内，这样可以提高定位部101和加热部件102的结合度，定位部101不易发生松动或脱落，定位部101的定位效果更好。
具体地，如图4所示，定位部101可以是方形块，则第一部分1011和第二部分1012同样是方形块状。定位部101也可以是圆柱状，则第一部分1011和第二部分1012同样是圆柱状。当然，第一部分1011和第二部分1012也可以构造为形状不同，例如，第一部分1011和第二部分1012中的一者为方形块状，另一者为圆柱状。第一部分1011和 第二部分1012的形状根据需要可具体设置，不限于此，这里不再赘述。
在本申请的一些实施例中，第一部分1011与加热部件102为一体件，例如，加热部件102和定位部101为金属件，第一部分1011与加热部件102一体铸造成型，当然，加热部件102和定位部101还可以是以其他方式构成一体件，这里不再赘述，通过这种方式可以使定位部101和加热部件102的连接更加牢固，降低脱落或松动的几率。
在本申请的一些实施例中，如图3所示，加热部件102的内侧面上设有安装槽102a，第一部分1011设在安装槽102a内。“内侧面”可以是指加热部件102的靠近定位空间一侧的侧面，例如，对左侧的加热部件102而言，内侧面即是指右侧面，对右侧的加热部件102而言，内侧面即是指左侧面。安装槽102a的形状与第一部分1011的形状相适配，例如，第一部分1011为方形块，则安装槽102a为方形槽，第一部分1011为圆柱，则安装槽102a为圆形槽。通过这种方式定位部101能在加热部件102上进行可拆卸安装，可以实现定位部101的更换。
例如，当某个定位部101损坏时，只需更换新的定位部101替换掉受损的即可，这样就能不用因某个定位部101受损而更换整个侧板定位组件10，有利于降低使用成本。
在本申请的一些实施例中，如图5所示，加热部件102上设有第一过孔102b，定位部101穿设在第一过孔102b内，且部分凸出加热部件102的内侧面。第一过孔102b的形状可以与定位部101的形状形同，具体可以参考前文，这里不再赘述。通过这种方式定位部101完全穿过加热部件102，使得定位部101与加热部件102的结合面更大，定位部101与加热部件102的连接可靠性更好。
在本申请的一些实施例中，定位装置100还包括加热部件102，加热部件102设在本体上。加热部件102的解释参考前文，这里不再赘述，也就是说，加热部件102和定位部101是两个相互独立的部件，两者安装在同一本体上。
在本申请的一些实施例中，如图2所示，加热部件102包括加热主体1021和柔性导热部1022，柔性导热部1022设在加热主体1021上，柔性导热部1022设在加热主体1021的靠近定位空间的一端上。
加热主体1021可以是指加热部件102中释放热源的部分。柔性导热部1022则是耐高温的柔性导热部分，例如，导热硅胶垫、导热橡胶垫等，由于柔性导热部1022具备一定的压缩量，因此可以更好地贴合在侧板210上，与侧板210的结合更紧密，更好地将加热主体1021上的热量传递到侧板210上，使得侧板210受热更加均匀。
可以理解为是，通过柔性导热部1022可以使加热部件102与侧板210进行软性接触，再加上多个定位部101能起到定位作用，也就是说，在静置工位能同时具备加热和 定位作用，侧板210的受热更加均匀，定位点更多，定位更准确，从而可以提升电池200的胶固化效果。
在本申请的一些实施例中，如图6所示，柔性导热部1022具有靠近定位空间设置的接触面1022a，定位部101具有靠近定位空间设置的定位面101a，接触面1022a的面积大于多个定位面101a的面积之和。接触面1022a可以是指柔性导热部1022与侧板210相接触的表面，定位面101a可以是指定位部101与侧板210相接触并起到定位作用的表面。通过接触面1022a的面积大于多个定位面101a的面积之和，这样在起到定位作用的同时，较大的接触面1022a使得加热部件102产生的热量可以更快地传递到侧板210上，侧板210被加热的速度更快，有利于提升胶固化效果。
在本申请的一些实施例中，定位部101为刚性定位部，通过这种方式定位部101能起到刚性定位支撑，有利于提升定位的精准性。
在本申请的一些实施例中，如图2所示，柔性导热部1022的围绕第二方向的周向边沿和加热主体1021的围绕第二方向的周向边沿保持平齐。例如，第二方向可以是指左右方向，即电池200的宽度方向，因此，“柔性导热部1022的围绕第二方向的周向边沿”可以是指柔性导热部1022的前后上下四个边沿，同样，“加热主体1021的围绕第二方向的周向边沿”可以是指加热主体1021的前后上下四个边沿。通过这种方式柔性导热部1022和加热主体1021的形状保持一致，整体性更好，同时柔性导热部1022和加热主体1021一侧的表面积大小相等，可以快速传导加热主体1021产生的热量。
例如，加热主体1021为长方形块，柔性导热部1022则为厚度较薄的长方形导热垫。
具体地，加热主体1021沿第一方向延伸，加热主体1021沿第一方向上的长度和侧板210的长度大体相等。也就是说，加热主体1021的长度可以是与侧板210的长度相等，也可以是加热主体1021的长度方向的两侧边紧邻侧板210的长度方向的两侧边，通过这种方式使柔性导热部1022和侧板210之间具有比较大的接触面1022a，对侧板210可以起到比较好的加热效果。
在本申请的一些实施例中，如图6所示，柔性导热部1022上设有第二过孔1022b，定位部101的靠近定位空间的部分设在第二过孔1022b内。当对电池200的侧板210进行定位时，随着本体逐渐靠近侧板210，柔性导热部1022首先接触侧板210并被压缩，而定位部101则能透过第二过孔1022b止抵在侧板210上，第二过孔1022b可以使柔性导热部1022不会影响定位部101的定位。采用这种方式定位部101和柔性导热部1022可以集中布置，侧板定位组件10的结构比较紧凑，可以节省空间。
具体地，如图4和图7所示，第二过孔1022b和定位部101的数量相等且一一对应， 例如，第二过孔1022b的数量为六个，定位部101的数量为六个，每个第二过孔1022b内设有一个定位部101。当然，这里只是举例说明，第二过孔1022b和定位部101的数量不限于此，还可以是其他数值，根据需要可具体设置，这里不再一一赘述。
在本申请的一些实施例中，如图6、图8所示，定位部101的位于第二过孔1022b内的部分上形成有定位面101a，柔性导热部1022具有靠近定位空间设置的接触面1022a，定位面101a与接触面1022a之间形成有压缩间隙10b，压缩间隙10b小于1mm。“压缩间隙10b”可以是指定位面101a与侧板210接触时柔性导热部1022所产生的压缩量，压缩间隙10b小于1mm既可以使柔性导热部1022与侧板210柔性接触，同时也使柔性导热部1022具备一定的刚性，可以对侧板210起到支撑维稳作用。
在本申请的一些实施例中，柔性导热部1022的厚度可以是4～6mm。例如，柔性导热部1022的厚度为4mm、5mm、6mm中的任一值。当然，柔性导热部1022的厚度不限于上述值，只要是4～6mm范围的数值即可，这里不再一一赘述。
在本申请的一些实施例中，如图8所示，定位部101包括定位主体1013和垫片1014，垫片1014为多个且层叠设置，多个垫片1014设在定位主体1013的远离柔性导热部1022的一端，多个垫片1014的数量可调，以调整定位主体1013在加热部件102的内侧面上的凸出长度。定位主体1013可以是指定位部101中起到定位作用的部件，例如，定位块或定位柱。垫片1014可以是指片状板材，垫片1014的形状可以与定位主体1013的形状相同，从而使整体上形状保持一致。通过调整垫片1014的数量就能改变定位主体1013在加热部件102的内侧面上的凸出长度，以适应调整侧板210对柔性导热部1022的压缩量，另一方面，也能适应性地调整对不同电池200的定位效果。
例如，当电池200的型号不同时，其大小同样可能不同，电池200在胶固化阶段时的轮廓变形量有所不同，外部移动部件推动定位部101顶压在侧板210上进行定位，为适应不同型号或大小的电池200，调整外部移动部件的运动参数比较麻烦，而通过增减垫片1014则能在外部移动部件的运动参数不变的条件下，使侧板定位组件10可以更好的适应不同的电池200，提高定位装置100的适应性。
具体地，定位主体1013可以是方形块，垫片1014可以是方形垫片。定位主体1013也可以是圆柱，则垫片1014可以是圆形垫片。定位主体1013和垫片1014的形状根据需要可以具体设置，这里不再赘述。
在本申请的一些实施例中，定位空间具有正交于第一方向和第二方向的第三方向，定位空间具有中心面，定位空间、加热主体1021、柔性导热部1022和定位部101在第三方向上均关于中心面呈对称设置。例如，第三方向可以是指上下方向，则“中心面” 可以是指在上下方向使定位空间、加热主体1021、柔性导热部1022和定位部101均各自呈对称设置的平面，通过这种方式使得加热主体1021、柔性导热部1022和定位部101居中设置，可以作用在电池200的侧板210的中心位置，带来更好的定位和支撑效果。
在本申请的一些实施例中，定位空间具有正交于第一方向和第二方向的第三方向，定位空间具有中心面，定位空间、加热主体1021和柔性导热部1022在第三方向上均关于中心面呈对称设置，多个定位部101在中心面的两侧依次交错布置。可以理解为，多个定位部101在中心面的两侧依次交错布置，不仅能作用在电池200的侧板210的中心区域，同时也能增加与侧板210的支撑面，定位和支撑效果更好。
根据本申请第二方面实施例的电池200的制造设备，包括前文的电池200的定位装置100。通过该制造设备可以在制造过程中对电池200的侧板210进行精准定位，能更好地控制电池200的侧面轮廓度。
在本说明书的描述中，参考术语“一些实施例”、“可选地”、“进一步地”或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本申请的实施例，本领域的普通技术人员可以理解：在不脱离本申请的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本申请的范围由权利要求及其等同物限定。
