背景技术
随着电池技术的发展，对电池小型化的要求越来越高，而电池最主要的部件是电芯，因此，对小型化电芯的加工质量要求也越来越高。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。

正如本申请的背景技术所述的，相关技术中，在卷针上设置有夹持件，例如内夹针，内夹针能够在料带卷绕于卷针之前将料带的卷绕初始端夹持固定于卷针上，从而达到阻止料带相对于卷针滑动的目的，在通过内夹针能够阻止料带相对于卷针滑动的情况下，当卷针座开始带动卷针旋转以将料带卷绕于卷针上时，料带可以在卷针上卷绕的比较工整。
但是，在对尺寸较小的电芯卷绕加工时，适配于较小电芯的卷针的尺寸也较小，碍于尺寸的限制，无法在卷针上设置夹持件以固定料带的卷绕起始端，这么一来，当卷针座开始带动卷针旋转时，会出现料带相对于卷针滑动的情况，导致后续卷绕于卷针上的料带比较杂乱，不够工整，卷绕效果较差。
为了解决背景技术中所提及的技术问题，本申请提供了一种卷绕装置，在卷针缝隙外设置有限位件，限位件能够将伸出卷针缝隙的料带以预设力固定，且预设力小于卷针座带动卷针旋转时对料带的卷绕拉力，因此，当卷针座带动卷针相对于安装台转动时，能够避免伸出于卷针缝隙的料带出现相对于卷针滑动的情况，同时能够保证伸出卷针缝隙的料带卷绕于卷针上，从而提高了料带的卷绕效果，另外，由于限位件设置卷针缝隙外，因此，该卷绕装置能够适用 于较小尺寸的电芯的卷绕。
下面通过具体的实施例对本申请进行详细说明：
参见图1和图2，本申请提供了一种卷绕装置100，该卷绕装置100包括放料机构110、安装台120、卷绕件130及限位件140，放料机构110用于传送料带10；卷绕件130包括卷针座131以及设置于卷针座131上的多个卷针132，卷针座131可旋转地设置于安装台120上，多个卷针132之间形成有卷针缝隙133，卷针缝隙133用于穿设料带10；限位件140设置于卷针缝隙133之外，限位件140用于将伸出卷针缝隙133的料带10以预设力固定，预设力为F1，卷针座131带动卷针132旋转时对料带10的卷绕拉力为F2，F1小于F2，以在卷针座131带动卷针132旋转时能够将预设长度的料带10卷绕于卷针132。
本实施例中，由于限位件140能够将伸出卷针缝隙133的料带10以预设力固定，且预设力小于卷针座131带动卷针132旋转时对料带10的卷绕拉力，因此，当卷针座131带动卷针132相对于安装台120转动时，能够避免伸出于卷针缝隙133的料带10出现相对于卷针132滑动的情况，同时能够保证伸出卷针缝隙133的料带10卷绕于卷针132上，从而保证了料带10卷绕于卷针132上的工整性，提高了料带10的卷绕效果。另外，由于限位件140设置于卷针缝隙133之外，因此，该卷绕装置100能够适配于较小尺寸的电芯卷绕。
在实际应用中，首先使得限位件140将伸出卷针缝隙133的料带10以预设力固定，然后使得卷针座131带动卷针132相对于安装台120旋转，从而将放料机构110传送的预设长度的料带10以及伸出卷针缝隙133的料带10均卷绕于卷针132上，以形成电芯的卷绕。
在一些可能的实施例中，参见图1和图3，限位件140可沿靠近或远离卷针132的方向运动，以将伸出卷针缝隙133的料带10以预设力固定或松开。
具体地，当限位件140沿靠近卷针132的方向运动时，限位件140能够将伸出卷针缝隙133的料带10以预设力固定。当限位件140沿远离卷针132的方向运动时，限位件140松开料带10，避免对卷针132的卷绕造成干涉。
由此，通过限位件140可沿靠近或远离卷针132的方向运动，以将伸出卷针缝隙133的料带10以预设力固定，能够使得限位件140灵活设置，并且能够在卷针132卷绕过程中避免限位件140对料带10的卷绕造成干涉。
限位件140的结构有多种，其中一些可能的结构中，参见图1和图3，限位件140包括第一驱动件1411和与第一驱动件1411连接的吸附件141，第一 驱动件1411用于带动吸附件141沿靠近或远离卷针132的方向移动，吸附件141用于将伸出卷针缝隙133的料带10吸附固定。
由此，通过吸附件141将伸出卷针缝隙133的料带10吸附固定，以在卷针座131带动卷针132相对于安装台120转动时使得放料机构110传送的料带10以及伸出卷针缝隙133的料带10均卷绕于卷针132上。另外，采用吸附件141对伸出卷针缝隙133的料带10进行固定，相较于采用夹持件固定卷绕于卷针132上的料带10的卷绕方案，能够避免对料带10的表面造成损伤，进一步保证了电芯的卷绕效果。
为了能够使吸附板吸附固定料带10，在一些可能的实施例中，参见图4，吸附件141为吸附板，吸附板朝向料带10的一侧设置有多个第一吸附孔1412。
由此，通过在吸附板朝向料带10的一侧设置多个第一吸附孔1412，能够保证吸附板吸附固定料带10的效果。
在限位件140的另一种可能的结构中，参见图5、图6和图7，限位件140包括第二驱动件1421和与第二驱动件1421转动连接的压辊142，第二驱动件1421用于带动压辊142沿靠近或远离卷针132的方向移动，压辊142用于将伸出卷针缝隙133的料带10挤压于卷针132上，以对料带10挤压固定。
由此，通过将伸出卷针缝隙133的料带10挤压于卷针132上，能够在卷针座131带动卷针132相对于安装台120转动的过程中阻止料带10相对于卷针132出现滑动的情况，从而使得卷针座131带动卷针132相对于安装台120转动时使得放料机构110传送的料带10以及伸出卷针缝隙133的料带10均卷绕于卷针132上。另外，采用压辊142将料带10挤压固定于卷针132的方式将伸出卷针缝隙133的料带10进行挤压固定，相较于采用夹持件固定卷绕于卷针132上的料带10的卷绕方案，能够避免对料带10的表面造成损伤，进一步保证了电芯的卷绕效果。
还需要说明的是，上述第一驱动件1411和第二驱动件1421均可以为直线电机或伸缩气缸。
由于压辊142是刚性的，因此，为了避免压辊142对料带10的过渡挤压，在一些可能的实施例中，参见图7，限位件140还包括与第二驱动件1421连接的安装座1422以及设置于安装座1422上的弹性件1423，压辊142设置于弹性件1423。
由于压辊142通过弹性件1423设置于安装座1422上，因此，当压辊142将料带10挤压于卷针132上时，弹性件1423能够缓冲部分压辊142与卷针 132之间的挤压力，从而避免压辊142对料带10过渡挤压。
其中，弹性件1423可以为弹簧、橡胶块等结构。
在一些可能的实施例中，参见图8，安装台120包括旋转盘121，旋转盘121可绕自身的中心轴线旋转；卷绕件130包括第一卷绕件134和第二卷绕件135，卷绕装置100具有卷绕工位151和下料工位152，当第一卷绕件134在卷绕工位151卷绕预设长度的料带10时，旋转盘121用于带动第一卷绕件134旋转至下料工位152、第二卷绕件135旋转至卷绕工位151，第二卷绕件135的卷针座131还用于带动卷针132相对于旋转盘121沿卷针132的轴向滑动伸出，以使料带10位于第二卷绕件135的卷针缝隙133中；卷绕装置100还包括切刀组件160，切刀组件160用于切断第一卷绕件134与第二卷绕件135之间的料带10，限位件140用于将切断后的伸出卷针缝隙133的料带10固定。
在实际应用中，首先使得第一卷绕件134位于卷绕工位151，并使得限位件140将伸出第一卷绕件134的卷针缝隙133的一段料带10进行固定，以在第一卷绕件134的卷针132转动时阻止该段料带10相对于卷针132滑动，同时，能够使伸出第一卷绕件134的卷针缝隙133的一段料带10卷绕于第一卷绕件134的卷针132上，当第一卷绕件134在卷绕工位151将放料机构110传送的预设长度的料带10卷绕于第一卷绕件134上时，旋转旋转盘121，以带动第一卷绕件134旋转至下料工位152、第二卷绕件135旋转至卷绕工位151，当第二卷绕件135位于卷绕工位151时，停止旋转盘121的旋转，与此同时，使得第二卷绕件135的卷针座131带动卷针132相对于旋转盘121沿卷针132的轴向滑动伸出，以使料带10位于第二卷绕件135的卷针缝隙133中，然后，使得限位件140将伸出第二卷绕件135上的卷针缝隙133的料带10以预设力进行固定，随后，采用切刀组件160将第一卷绕件134与第二卷绕件135之间的料带10切断，最后，使得第二卷绕件135的卷针座131带动其对应的卷针132相对于旋转盘121转动，以将放料机构110传送的预设长度的料带10以及伸出第二卷绕件135的卷针缝隙133的料带10卷绕于第二卷绕件135的卷针132上。
另外，同理的，当第二卷绕件135的卷针132卷绕完成卷绕后，且第一卷绕件134完成下料后，再一次转动旋转盘121，将第一卷绕件134旋转至卷绕工位151、第二卷绕件135旋转至下料工位152，以进行第一卷绕件134的再一次卷绕，依次类推，能够进行第一卷绕件134和第二卷绕件135的多次卷绕。
可见，当卷绕件130包括第一卷绕件134和第二卷绕件135时，能够在第 一卷绕件134上完成电芯卷绕时，通过旋转盘121将第一卷绕件134旋转至下料工位152、第二卷绕件135旋转至卷绕工位151，如此一来，可以缩短第一卷绕件134和第二卷绕件135的卷绕时间，提高电芯的卷绕效率。
在一些可能的实施例中，参见图8和图9，切刀组件160包括切刀驱动件161和与切刀驱动件161连接的切刀162，切刀驱动件161用于带动切刀162朝向料带10移动，以切断第一卷绕件134与第二卷绕件135之间的料带10。
由此，通过切刀驱动件161带动切刀162将第一卷绕件134与第二卷绕件135之间的料带10切断，相较于人为手动切断第一卷绕件134与第二卷绕件135之间的料带10，进一步地提高了卷绕装置100的卷绕效率。
其中，切刀驱动件161可以为伸缩气缸，也可以为直线电机等。
可选的，料带10可以为两层层叠设置的隔膜，或者，可选的，料带10可以为两层层叠设置的隔膜以及夹设于两层隔膜之间的极片。
在电芯的卷绕中，当料带10包括两层隔膜，且切刀162切断第一卷绕件134与第二卷绕件135之间的料带10时，两层隔膜极易移位，从而影响卷芯的卷绕效果。基于此，在一些可能的实施例中，参见图9，切刀162内设置有加热棒163，加热棒163用于对切刀162加热。
由于加热棒163能够对切刀162进行加热，因此，当切刀162切断料带10时，能够使得两层隔膜粘接在一起，从而避免了两侧隔膜的移位，进而保证了卷芯的卷绕效果。
在切刀162切割料带10时，由于料带10是柔性的，因此，为了保证切刀162的切割效果，在一些可能的实施例中，参见图10，安装台120还包括连接轴123以及设置于连接轴123上的抵靠件122，抵靠件122用于在切刀162切断第一卷绕件134与第二卷绕件135之间的料带10时对料带10提供抵靠力，旋转盘固定于连接轴123。
由于在连接轴123上设置抵靠件122，且抵靠件122在切刀162切割料带10时对料带10提供抵靠力，因此，切刀162对料带10的抵接力与抵靠件122对料带10的抵靠力的方向相反，从而避免了料带10在切刀162切割时沿切刀162抵接力的方向移动，保证了切刀162对料带10的切割效果。
进一步地，在一些可能的实施例中，参见图10，抵靠件122设置有避让槽1221，避让槽1221用于避让切刀162。
由此，通过设置避让槽1221，能够使切刀162切割料带10时避让切刀162，从而使得切刀162能够穿透料带10插设于避让槽1221内，保证了切刀162 的切割效果。
在一些可能的实施例中，参见图11，抵靠件122朝向料带10的一侧设置有第一吸附板1222和第二吸附板1223，第一吸附板1222与第二吸附板1223之间具有避让间隙，避让间隙形成避让槽1221，第一吸附板1222与第二吸附板1223用于吸附料带10。
具体地，第一吸附板1222和第二吸附板1223上均设置有多个第二吸附孔1224。
由此，切刀162在切割料带10时，首先，使得第一吸附板1222与第二吸附板1223将料带10吸附固定于抵靠件122上，然后切刀驱动件161带动切刀162朝向抵靠件122运动至切刀162穿透料带10并插设于避让槽1221内，完成切刀162对料带10的切割，可见，通过设置第一吸附板1222与第二吸附板1223，能够在切刀162切割料带10时，保证料带10设置的稳定性，进而保证了切刀162对料带10的切割效果。
在一些可能的实施例中，参见图12和图13，卷绕装置100还包括收尾组件170，收尾组件170包括靠近下料工位152设置的收尾压紧件171，收尾压紧件171用于将靠近下料工位152的切断后的料带10压紧于下料工位152的卷绕件130上。
其中，上述收尾压紧件171用于将靠近下料工位152的切断后的料带10压紧于下料工位152的卷绕件130上，应理解，当第一卷绕件134位于下料工位152时，收尾压紧件171用于将卷绕于第一卷绕件134的卷针132上的一段料带10压紧于第一卷绕件134的卷针132上，或，当第二卷绕件135位于下料工位152时，收尾压紧件171用于将卷绕于第二卷绕件135的卷针132的一段料带10压紧于第二卷绕件135的卷针132上。
由此，当切刀162切断第一卷绕件134与第二卷绕件135之间的料带10时，通过设置收尾压紧件171，能够保证收卷于第一卷绕件134或第二卷绕件135上的一段料带10的卷绕效果。
具体地，收尾压紧件171包括支座1711以及设置于支座1711上的压紧驱动件1712和连接于压紧驱动件1712上的压紧滚轮1713，当压紧驱动件1712带动压紧滚轮1713压紧于下料工位152上的卷针132上时，一方面，压紧滚轮1713能够对料带10进行压紧，使其收卷于下料工位152的卷针132上，保证料带10的卷绕效果，另一方面，由于压紧滚轮1713与料带10之间时滚动抵接，因此，能够减少料带10与压紧滚轮1713之间的摩擦力，进一步保证了 料带10的卷绕效果。
在一些可能的实施例中，参见图12和图13，收尾组件170还包括靠近下料工位152设置的收尾吸附件172，收尾吸附件172用于吸附靠近下料工位152的切断后的料带10，以防止料带10的自由端摆动。
通过设置收尾吸附件172，能够对卷绕于位于下料工位152的卷针132上的一段料带10进行吸附，从而提高了第一卷绕件134的收卷效果。
具体地，收尾吸附件172包括设置于支座1711上的吸附驱动件1721和与吸附驱动件1721连接的收尾吸附板1722，在切刀162切断第一卷绕件134和第二卷绕件135之间的料带10时，吸附驱动件1721带动收尾吸附板1722朝向料带10移动，以将卷绕于第一卷绕件134的卷针132上的一段料带10吸附，起到防止切断后的料带10出现摆尾的情况，进而保证了电芯的卷绕效果。
