随着电池技术的发展,电池已经进入了工作生活的方方面面。小到手机电池,大到新能源汽车的电池模组,无处不见锂电池的身影。电池单体一般包括电极组件。电极组件包括正极、负极以及隔离件。在电池单体充放电过程中,活性离子(例如锂离子)在正极和负极之间往返嵌入和脱出。隔离件设置在正极和负极之间,可以起到防止正负极短路的作用,同时可以使活性离子通过。正极和负极的活性物料层所选用的材料不同。在正极材料当中,最常用的材料有钴酸锂,锰酸锂,磷酸铁锂和三元材料(镍钴锰的聚合物)。在负极材料当中,目前主要以天然石墨和人造石墨为主,此外还有氮化物、PAS、锡基氧化物、锡合金、纳米负极材料,以及其他的一些金属间化合物等。在形成电极组件时,在一些制作工艺中,需要经过浆料制备、涂布、冷压、卷绕、热压、装配、注液、化成。
在进行电池单体制造工艺过程中,为了支承电池单体的重量,需要在电池单体的底部设置托盘,通过托盘支承电池单体,以使电池单体能够按照需要向预设位置移动。在一些情形下,托盘采用整体片状结构,以承载电池单体的整体重量,但是导致托盘的重量增大,大大提升了化成工艺中的所需能耗。
请参阅图1和图2,本申请的示例提出一种用于承载电池单体的托盘,托盘包括外固定架10和多个支撑梁20,外固定架10内侧形成有安装空间;多个支撑梁20设于安装空间内,多个支撑梁20沿第一方向(即如图1中1a方向)排列,多个支撑梁20分别与外固定架10相连接;至少两个支撑梁20相间隔设置;多个支撑梁20用于承载电池单体80。
外固定架10形成具有安装空间的整体框架,所述外固定架10可以为大体形状呈矩形的框架结构,外固定架10内部形成安装空间,以使外固定架10整体形成中空框架。
支撑梁20的数量为多个,多个支撑梁20均安装于安装空间内,即,多个支撑梁20均安装在外固定架10的内侧。支撑梁20用于承载电池单体80,以使电池单体80保持在预设位置。支撑梁20与外固定架10相互连接固定,以使多个支撑梁20能够与外固定架10同步移动。多个支撑梁20沿第一方向排列,所述第一方向可以为外固定架10的长度方向,也可以为宽度方向,本示例中的第一方向为外固定架10的宽度方向。
本示例中,多个支撑梁20形成用于承载电池单体80的支撑部位,支撑梁20形成用于支撑电池单体80的支撑面。多个支撑梁20中,至少两个支撑梁20相互间隔设置,是指其中至少两个支撑梁20是相互分隔开,对应两个支撑梁20相互之间不连接。由于支撑梁20可以相互间隔设置,使得多个支撑梁20形成的支撑部位不能形成一个整体,使得用于支撑电池单体80的支撑部位上形成有间隙,进而可以使支撑梁20用于承载电池单体80的同时,支撑梁20所形成的支撑面不能形成一个完整的平面。
由于形成的支撑部位具有间隙,可以减小支撑部位的整体重量,进而减轻托盘的重量。由于外固定架10能够形成托盘的外部框架,电池单体80安装在外固定架10内侧的支撑梁20上,支撑梁20承载电池单体80的重量。通过间隔设置的支撑梁20来承载电池单体80,相互间隔设置的支撑梁20之间不存在相互牵引的作用力,当电池单体80安装于托盘上时,使电池单体80作用于相互间隔的支撑梁20上的重量被分散开,即使单个支撑梁20产生变形,支撑梁20之间也不存在相互牵引作用力,进而可以防止支撑梁20之间相互作用而导致多个支撑梁20所形成的支撑部位整体变形。由于多个支撑梁20分别与外固定架10相互连接,在安装时,可以方便对各支撑梁20与外固定架10分别进行连接固定,进而可以提升支撑梁20的安装性能。
在进行电池单体80化成工艺时,需要将电池单体80与托盘一起移动至预设工位。本示例中,相互间隔设置的两个支撑梁20可以分别用于与外部支撑结构相配合,以使外部支撑结构分别作用于多个支撑梁20上,进而可以分散外部支撑结构对托盘的相对作用力。当托盘与外部支撑结构相互作用时,由于支撑梁20之间具有间隙,使得外部支撑结构用于承载托盘的部位之间可以相互错开,进而可以防止外部支撑结构的多个承载部位之间相互干涉。由于在进行化成工艺时,电池单体80会处于有电解液的环境,当电解液流到托盘上时,电解液可以沿着相邻支撑梁20之间的间隙流出,进而防止托盘上电解液堆积造成托盘腐蚀的问题。当电解液沿着相邻支撑梁20之间的间隙流出时,安装于托盘上的电池单体80也不容易相对托盘产生滑动,进而可以提升电池单体80的稳定性。
在一些示例中,电池单体80的数量为至少两组,每一组包括至少一个电池单体80。电池单体80的组数与支撑梁20的组数相同,每一支撑梁20对应承载一组电池单体80,以使多组电池单体80相互不干涉。由于承载不同组电池单体80的支撑梁20之间相互不干涉,使得单个支撑梁20产生形变时,对其他支撑梁20不产生影响,进而防止托盘产生整体变形。
在一些示例中,托盘包括多个沿第一方向设置的支撑梁20,多个支撑梁20沿第一方向均呈间隔设置,以使每个支撑梁20与其相邻的支撑梁20之间均相互隔开,每个支撑梁20对相邻中的支撑梁20均不产生影响。
在一些示例中,外固定架10为长方形框架结构,安装空间大体呈长方形,多个支撑梁20安装于安装空间内。进一步地,在一些示例中,其中至少两个支撑梁20平行于外固定架10的长度方向设置,相互平行的两个支撑梁20及与之相邻的支撑梁20之间具有间隙,以使两个相互平行的支撑梁20能够分别用于承载电池单体80。
在一些示例中,支撑梁20的厚度与外固定架10的厚度相等,以使托盘摆放在预设平台上时,支撑梁20和外固定架10均能够支撑在预设平台上。在一些示例中,支撑梁20的厚度小于外固定架10的厚度,以使外固定架10支撑在预设平台上,支撑梁20被悬置在预设平台的上方。
请参阅图2至图6,在一些示例中,外固定架10为整体框架结构,支撑梁20固定在呈整体状态的外固定架10上。在一些示例中,外固定架10为多个固定梁相互组合而成的框架型结构。
请参阅图1、图7、图8和图9,进一步地,在一些示例中,多个支撑梁20均相互平行设置。在一些示例中,多个支撑梁20具有沿第一方向上的首梁和尾梁,首梁和尾梁即位于第一方向两端的支撑梁20,其中,首梁和尾梁相互平行设置,并且首梁和尾梁与邻近首梁和尾梁的支撑梁20之间相互间隔设置,以使首梁和尾梁分别形成独立的支撑部位。在一些示例中,在首梁和尾梁之间具有中间梁,中间梁相对首梁以及尾梁间隔设置。在一些示例中,外固定架10的内侧安装有三个上述任一示例中所述的支撑梁20,三个支撑梁20沿着第一方向间隔设置,并且三个支撑梁20相互平行设置。其中,位于第一方向的两端带两个支撑梁20分别为首梁和尾梁,首梁和尾梁分别通过上述任一示例中所述的第一加强件30与外固定架10相连接,位于中部的支撑梁20为中间梁,中间量通过上述任一示例中所述的第二加强件40与上述首梁和尾梁相互连接固定。
请参阅图3、图4、图5以及图6,在一些示例中,外固定架10为中空管状结构,以使外固定架10整体呈中空结构,进而可以减轻外固定架10的整体重量。所述外固定架10可以为整体注塑成型,可以 为注塑、卷绕或弯折等工艺组合加工而成。进一步地,在一些示例中,外固定架10为一个整体,通过一个管状结构围合形成所述外固定架10。在一些示例中,外固定架10由多个中空管状结构组合而成框架型结构。
在一些示例中,外固定架10为碳纤维材料制成。碳纤维材料是一种复合材料,是由树脂基体与短纤维构成的碳纤维束进行浸渍融合的复合材料。在进行加工时,在预设模具内加入熔融的包含树脂集体和碳纤维束的预浸料,待模具内的产品成型为预设形状。通过采用碳纤维材料形成外固定架10,能够有效提升外固定架10的整体耐腐蚀性能和结构强度,使得电池单体80进行化成工艺时,在电解液环境内不容易产生腐蚀和磨损。
在一些示例中,支撑梁20为中空管状结构,以减轻支撑梁20的整体重量,进而可以实现托盘的轻型化设计。本示例中的支撑梁20可以为整体注塑成型的中空管状,也可以为注塑、卷绕以及弯折等工艺组合加工而成。本示例中的支撑梁20可以与外固定架10采用相同工艺制成。
在一些示例中,支撑梁20为上述示例所述的碳纤维材料制成。进一步地,支撑梁20可以与外固定架10采用相同材料制成。
请参阅图3、图4和图7,在一些示例中,支撑梁20和外固定架10的其中一者设有第一凸台111,另一者凹设有第一卡槽21;第一凸台111插接于第一卡槽21,以将支撑梁20与外固定架10连接。第一凸台111和第一卡槽21相互配合,以将支撑梁20和外固定架10相互连接固定。通过采用插接固定,能够方便支撑梁20和外固定架10的相互连接,以实现支撑梁20和外固定架10的快速组装。
进一步地,在一些示例中,支撑梁20上设置有第一卡槽21,外固定架10上设有第一凸台111,第一凸台111插接于第一卡槽21。在一些示例中,第一卡槽21为开设于支撑梁20的端部的凹槽。在一些示例中,支撑梁20整体呈中空管状结构,第一卡槽21为支撑梁20的内壁面围合而成凹槽。在一些示例中,外固定架10与第一凸台111一体设置,以使外固定架10与第一凸台111快速成型。进一步地,在一些示例中,外固定架10和第一凸台111均为上述任一示例中所述的碳纤维材料制成,以提升托盘的整体结构强度。
在一些示例中,支撑梁20上设置有上述第一凸台111,第一凸台111可以与支撑梁20一体设置,或者,分别成型支撑梁20和第一凸台111之后,将第一凸台111固定安装在支撑梁20上。外固定架10上设置有上述第一卡槽21,第一卡槽21可以为开设于外固定架10上的凹槽,以在对外固定架10进行成型时,可以同时形成第一卡槽21。
在一些示例中,在支撑梁20上同时设置有第一凸台111和第一卡槽21,在外固定架10上也同时设置有第一凸台111和第一卡槽21,支撑梁20上的第一凸台111插接于外固定架10上的第一卡槽21,外固定架10上的第一凸台111插接于支撑梁20的上的第一卡槽21,进而实现两者相互插接固定。
在一些示例中,第一凸台111还与第一卡槽21粘接连接;当第一凸台111与第一卡槽21相互插接之后,第一凸台111的外壁面与第一卡槽21的内壁面之间的间隙内填充粘接剂,以使第一凸台111与第一卡槽21的内壁面相互粘接固定,进而可以防止第一凸台111相对第一卡槽21产生移动,避免支撑梁20相对外固定架10产生振动,进而有助于提升支撑梁20的稳定性。另外,由于可以通过粘接剂填充第一凸台111与第一卡槽21的内壁面之间的间隙,以防止电解液等液体进入第一凸台111和第一卡 槽21之间的间隙内,进而防止在支撑梁20或外固定架10的内部存积电解液导致托盘内部产生腐蚀等问题。在进行电池单体80的化成的工艺时,需要使电池单体80保持在相对较为洁净的场景,本示例中的粘结剂将外固定架10与支撑梁20的连接部位之间的间隙填充起来,可以防止两者之间的间隙中积存的杂质进入电池单体80化成工艺设备,进而可以防止设备污染,有助于提升产品加工质量。
由于采用第一凸台111与第一卡槽21相互插接配合时,第一凸台111与第一卡槽21之间存在有间隙,导致相应结构会产生一定程度的移动窜动。当采用粘接剂填充第一凸台111与第一卡槽21之间的间隙之后,在粘接剂凝固之前,粘接剂呈现可变形状态,因此,可以在粘接剂凝固之前相对移动粘接剂的粘接对象,以实现对对应结构的相对位置进行调整。
在一些示例中,外固定架10上设有第一凸台111,第一凸台111与外固定架10粘接连接。本示例中,将第一凸台111安装于外固定架10上,在支撑梁20上设置有上述任一示例中所述的第一卡槽21。第一凸台111与外固定架10为分体结构,并且,第一凸台111与外固定架10粘接连接,进而实现第一凸台111的安装固定。本示例中,可以将第一凸台111和外固定架10分别单独成型之后,将第一凸台111粘接在外固定架10上,进而可以实现两者的独立成型,以提升成型效率,简化成型模具的加工设计。由于粘接剂可以填充在第一凸台111和外固定架10之间的间隙内,防止第一凸台111与外固定架10相连接部位产生腐蚀或磨损,进而提升产品质量。
通过采用粘接剂进行粘接,可以在粘接剂凝固之前调整第一凸台111在外固定架10上的安装位置,进而可以实现第一凸台111的位置调节。由于第一凸台与支撑梁20相互配合,当第一凸台111的位置调整时,支撑梁20的相对位置也会产生变化,进而可以有利于对支撑梁20的相对位置进行调整,以减小支撑梁20的安装误差。
本示例中,在完成第一凸台111、外固定架10以及支撑梁20的成型之后,可以先将第一凸台111插接进入支撑梁20的第一卡槽21内,然后将第一凸台111与外固定架10相粘接。进一步地,在一些示例中,在将第一凸台111插接进入第一卡槽21内之后,在第一凸台111的外壁面与第一卡槽21的内壁面之间填充粘接剂,并通过粘接剂将第一凸台111与外固定架10相互粘接固定。
进一步地,在一些示例中,第一凸台111采用上述任一示例中所述的碳纤维材料制成,以提升第一凸台111的结构强度和耐腐蚀性能。

在一些示例中,第二凸台121与第二卡槽31的内壁面相互粘接,以防止第一加强件30相对第二凸台121产生抖动,进而有助于提升第一加强件30的结构强度和稳定性。利用粘接剂填充第二凸台121与第二卡槽31之间的间隙,可以防止电解液等杂质进入第二凸台121与第二卡槽31之间的间隙,以方便后续对托盘进行清洁,避免托盘受到污染。
在一些示例中,第一加强件30和外固定架10相互粘接连接。本示例中,第一加强件30和外固定架10分别单独成型之后,再通过粘接剂将第一加强件30与外固定架10相互粘接固定。

在一些示例中,与前一示例的不同之处在于,外固定架10具有上表面,上述示例中所述的销孔123贯通至外固定架10的上表面。
请参阅图9、图10和图11,在一些示例中,托盘还包括安装于外固定架10内的限位组件50,限位组件50开设有销孔123;外固定架10上对应销孔123的位置开设有过孔521。
本示例中的所述限位组件50用于形成销孔123。销孔123可以为开设于限位组件50上的贯通孔或沉孔,外固定架10上的过孔521与销孔123的位置相对应,以使外部销钉等结构能够贯穿过孔521并插入销孔123内。
在一些示例中,外固定架10为中空结构,限位组件50安装于外固定架10内。

在一些示例中,固定块51上设置有凸耳513,凸耳513与外固定架10相连接固定。所述凸耳513凸出设置在固定块51上,凸耳513作为固定块51与外固定架10的中间连接件,以方便对固定块51进行安装。在一些示例中,凸耳513上设置有螺纹孔114,外固定架10上设置有螺钉孔124,在外固定架10上设置有螺钉,螺钉贯穿外固定架10上的螺钉孔124,并与凸耳513上的螺纹孔114螺纹连接。在一些示例中,凸耳513以及固定块51均与外固定架10的内壁面相粘接固定,通过设置凸耳513,可以增大限位组件50与外固定架10的接触面积,进而提升固定块51的稳定性。
在一些示例中,凸耳513设于固定块51远离过孔521的一端。由于凸耳513可以作为外固定架10 与固定块51的中间连接件,当凸耳513远离过孔521设置时,用于连接凸耳513的螺钉等连接件60可以远离过孔521设置,以减少在外固定架10的同一表面上进行开孔等加工。进一步地,本示例中的凸耳513通过上述示例中的螺钉与外固定架10相连接。
请参阅图1和图12,在一些示例中,外固定架10包括两个第一固定梁11以及两个第二固定梁12,两个第一固定梁11与两个第二固定梁12沿第三方向相互交替首尾连接,以使两个第一固定梁11与两个第二固定梁12围合形成安装空间;至少两个支撑梁20的端部分别与两个第一固定梁11相连接固定。

本示例中,至少两个支撑梁20的端部分别与两个第一固定梁11相连接固定。所述支撑梁20的端部,是指支撑梁20沿着第二方向上的两个端部。进一步地,两个第一固定梁11分别设置在支撑梁20沿第二方向上的两端,两个第二固定梁12分别设置在支撑梁20沿第一方向上的两侧,本示例中的多个支撑梁20均分别与两个第一固定梁11相连接。本示例中的第三方向是指顺时针方向或逆时针方向。
通过采用两个第一固定梁11和两个第二固定梁12相互配合形成外固定架10,以使外固定架10内围合形成安装空间。由于可以将第一固定梁11和第二固定梁12分别成型,进而可以有效简化相应结构的加工模具,提升产品加工效率。在一些示例中,第一固定梁11和第二固定梁12均为中空管状结构,以减轻外固定架10的整体重量。在一些示例中,第一固定梁11和第二固定梁12均为碳纤维材料制成,以提升第一固定梁11和第二固定梁12的结构强度和耐腐蚀性能。

在一些示例中,与前述示例不同之处在于,在第二固定梁12上开设有第五卡槽112,在第一固定梁11上设置有第五凸台122。
在一些示例中,第五凸台122还与第五卡槽112粘接连接;通过粘接剂填充第五凸台122与第五卡槽112之间的间隙,以防止杂质进入两者之间的间隙内而造成的污染。在一些示例中,第一固定梁11为中空管状结构,第五凸台122插接于第五卡槽112内之后,通过粘接剂将两者之间的间隙封堵起来,防止杂质积存在第一固定梁11内部,进而防止托盘进入化成等工艺设备内时,杂质对工艺产生影响。
在一些示例中,第五凸台122与第二固定梁12插接连接,以使第五凸台122和第二固定梁12可以分别成型,进而可以简化成型步骤。本示例中,第五凸台122可以与第二固定梁12采用相同的材料制成。
在一些示例中,第五凸台122与第二固定梁12粘接连接。通过采用粘接方式,可以将第五凸台122与第二固定梁12分别成型之后再进行组装。由于采用粘接方式,可以减少在第二固定梁12上进行开孔等加工,有助于提升第二固定梁12的结构强度。
进一步地,在一些示例中,第五凸台122与第五卡槽112相互粘接之后,将第五凸台122粘接在第二固定梁12上,进而提升第五凸台122的粘接效率。由于可以直接通过粘接剂填充第五凸条与第五卡槽112之间的间隙,以及第五凸台122与第二固定梁12之间的间隙,进而可以有效避免不同部位的连接件60之间的间隙积存杂质的问题。

请结合参阅图1至图15,在一些示例中,托盘用于在电池单体80进行化成等工艺时承载电池单体80。托盘包括外固定架10和设置在外固定架10内侧的多个支撑梁20,其中至少两个支撑梁20呈间隔设置,以减轻托盘的整体重量。本示例中的外固定架10为两个第一固定梁11和两个第二固定梁12相 互连接围合形成的长方形结构。其中,多个支撑梁20分别与两个第一固定梁11相互连接。本示例中的支撑梁20和外固定架10可以均采用碳纤维材料制成,以提升托盘的耐腐蚀性能。在组装支撑梁20和外固定架10时,可以采用第一凸台111与第一卡槽21相配合方式,实现支撑梁20的组装;为了避免支撑梁20产生抖动,在第一凸台111和第一开槽的接合面之间的间隙填充有粘接剂,以防止支撑梁20产生抖动时造成的磨损。本示例中,在支撑梁20与外固定架10之间设置有第一加强件30,在相邻的支撑梁20之间设置有第二加强件40,其中第一加强件30和第二加强件40也可以采用碳纤维材料制成。为了方便产品的移动和堆放,在外固定架10上设置有销孔123,通过销孔123与外部销钉等结构相配合,以实现对托盘的限位和固定。在外固定架10上设置有用于连接端板71的连接件60,以方便在拘束电池单体80时,对端板71进行限位。本示例中,不同零部件之间可以通过粘接剂相互连接,在粘接剂凝固之前,可以对相应的零部件进行位置调整,进而实现对应结构位置的微调。
以上所述仅为本申请的可选示例,并非因此限制本申请的专利范围,凡是在本申请的发明构思下,利用本申请说明书及附图内容所作的等效结构变换,或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
