具体实施方式
下面结合附图来对本发明的技术方案作进一步的阐述。
本发明的电池片裂片装置用于将电池片分裂成至少两片。如图1～图9所示，该电池片裂片装置包括基座1和设置在基座1上的电池片固定装置。
电池片固定装置包括至少两个固定单元，多个固定单元中的至少一个固定单元为能够相对其他固定单元翻转的可翻转固定单元，当可翻转固定单元翻转至设定位置时，其上固定的电池片与其他固定单元上的电池片分开。
多个固定单元沿水平方向并排设置，可翻转固定单元的翻转轴线沿垂直于多个固定单元排列的方向延伸，可翻转固定单元的翻转角度不超过90°。具体的，各可翻转固定单元均包括能够转动地设置在基座1上的固定基板，多个固定单元的排列方向为固定基板的宽度方向，固定基板的翻转轴线的延伸方向为固定基板的长度方向，固定基板的翻转轴线位于固定基板的一侧。本实施例中，固定单元为吸盘组件2，固定基板为吸盘组件2的吸盘21。
具体的，每组吸盘组件2还均包括分别设置在吸盘21的左右两端的连接座22和真空组件，多个吸盘21相平行设置，每个吸盘21的内部均具有一中空腔体，每个吸盘21远离基座1的底部的一端面上设置有吸附口21a，中空腔体分别与吸附口21a和真空组件相连通。通过真空组件使吸盘21的中空腔体中产生真空，并通过吸附口21a将电池片吸附固定在吸盘21上。
多个固定单元沿水平方向并排设置，本实施例中，位于最外侧的一个固定单元固定地设置在基座1上，其余固定单元均为可翻转固定单元。即，该电池片固定装置包括一组固定吸盘组件2a和多组活动吸盘组件2b。
该电池片裂片装置还包括用于驱动活动吸盘组件2b相对转动的驱动装置。具体的，驱动装置包括动力装置51、驱动板52和第一驱动轴53，驱动板52能够沿上下方向滑动地设置在基座1上，动力装置51用于驱动驱动板52在基座1上上下滑动，每组活动吸盘组件2b上均固定设置有一根第一驱动轴53，每根第一驱动轴53均与驱动板52相配合。当动力装置51驱动驱动板52沿基座1向上或向下滑动时，通过驱动板52与第一驱动轴53的配合驱使第一驱动轴53带动活动吸盘组件2b相对转动，从而实现将电池片自动分裂。
一种具体的实施方式，驱动板52上设置有第一滑槽521，第一滑槽521的数量与第一驱动轴53的数量相对应，当第一滑槽521设置有多组时，沿驱动板52的长度延伸方向，多个第一滑槽521依此顺序为521-1、521-2、521-3……，每组第一滑槽521均包括沿竖直方向延伸的第一直槽521a和自第一直槽521a的上端向着一侧弯折并延伸形成的的第一斜槽521b，每组第一驱动轴53穿设在一组第一滑槽521中，并能够沿第一滑槽521的长度延伸方向相对第一滑槽521滑动地设置。当动力装置51驱动驱动板52在基座1上向上或向下滑动时，第一驱动轴53在第一滑槽521中滑动，当第一驱动轴53进入到第一斜槽521b中并在第一斜槽521b中滑动时，通过第一斜槽521b的斜面与第一驱动轴53的配合，使得第一驱动轴53带动与其相连接的活动吸盘组件2b相对其他活动吸盘组件2b转动，从而将电池片分裂。
第一直槽521a与第一斜槽521b的相交处形成第一滑槽521的第一拐点A1，在驱动板52上，自驱动板52的一侧向着另一侧的方向，多组第一滑槽521中，第一拐点A1距离基座1的底部的高度逐渐增加，这样，当第一根第一驱动轴53进入到第一个第一滑槽521-1的第一斜槽521b中并沿第一斜槽521b滑动，以驱使与其相连接的活动吸盘组件2b翻转分裂第一片电池片时，剩余的第一驱动轴53均位于第一直槽521a中，与剩余的第一驱动轴53相连接的活动吸盘组件2b均处于初始状态；当第二根第一驱动轴53进入到第二个第一滑槽521-2的第一斜槽521b中并沿第一斜槽521b滑动，以驱使与其相连接的活动吸盘组件2b翻转分裂第二片电池片时，除第一个第一滑槽521-1和第二个第一滑槽521-2中的第一驱动轴53外，剩余的第一驱动轴53仍然均位于第一直槽521a中，与剩余的第一驱动轴53相连接的活动吸盘组件2b仍处于初始状态，依此循环，直至将电池片顺序逐片分裂。
活动吸盘组件2b能够沿水平方向能够滑动地设置在基座1上，这样，当一片电池片分裂完成后，通过驱使活动吸盘组件2b相对基座1沿水平方向滑动，可使分裂后的电池片与剩余的电池片之间拉开一定距离，从而方便后续电池片的裂片操作。具体的，裂片装置还包括多个沿水平方向滑动地设置在基座1上的安装部3，多个活动吸盘组件2b分别能够转动地设置在多个安装部3上。
本实施例中，每个安装部3均呈开口朝上的U字型结构，活动吸盘组件2位于U字型结构的U型槽内，每组活动吸盘组件2b的左右两端的连接座22均通过转轴4与安装部3的U字型结构的两边相转动连接，固定吸盘组件2a的左右两端的连接座22与安装部3的U字型结构的两边固定连接。
具体的，该电池片裂片装置还包括第二驱动轴6，每个安装有活动吸盘组件2的安装 部3上均固定设置有一根第二驱动轴6，驱动板52上还设置有第二滑槽522，第二滑槽522的数量与第二驱动轴6的数量相对应，且一一对应设置在每个第一滑槽521的下侧方，当第二滑槽522设置有多组时，沿驱动板52的长度延伸方向，多个第二滑槽522依此顺序为522-1、522-2、522-3……，每组第二滑槽522均包括沿竖直方向延伸的第二直槽522a和自第二直槽522a的上端向着一侧弯折并延伸形成的第二斜槽522b，第二斜槽522b与第一斜槽521b的倾斜角度相同，每组第二驱动轴6穿设在一组第二滑槽522中并能够沿第二滑槽522的长度延伸方向相对第二滑槽522滑动地设置。当动力装置51驱动驱动板52在基座1上向上或向下滑动时，第二驱动轴52在第二滑槽522中滑动，当第二驱动轴6进入到第二斜槽522b中并沿第二斜槽522b滑动时，通过第二斜槽522b的斜面与第二驱动轴6的配合，使得第二驱动轴6带动与其固定连接的安装部3相对基座1沿水平方向滑动。
第二直槽522a与第二斜槽522b的相交处形成第二滑槽522的第三拐点B1,对于相对应设置的一个第一滑槽521和一个第二滑槽522来说，当驱动板52相对基座1向下滑动时，第一驱动轴53从初始位置到第一拐点A1的距离小于第二驱动轴6从初始位置到第三拐点B1的距离，这样，当一根第一驱动轴53经过第一拐点A1进入第一斜槽521b中并沿第一斜槽521b滑动，从而驱动一组活动吸盘组件2b相对安装部3转动裂片的过程中，位于同一安装部3上的第二驱动轴6还位于第二滑槽522的下部的第二直槽522a中，当裂片完成后，第二驱动轴6才经第三拐点B1进入第二斜槽522b中并沿第二斜槽522b滑动，从而驱使安装部3带动活动吸盘组件2b一起相对基座1沿水平方向滑动，以拉开分裂后的电池片与剩余的电池片之间的距离。
当前第一驱动轴53的初始位置距第一拐点A1的距离大于与其相邻的前一个第二驱动轴6距第三拐点B1的距离，这样，使得前一个活动吸盘组件2b沿水平方向移动一距离后当前活动吸盘组件2b才发生翻转。即当一根第二驱动轴6进入到第一个第二滑槽522-2的第二斜槽522b中沿第二斜槽522b滑动，以驱使与其相连接的安装部3相对基座1沿水平方向滑动时，剩余的活动吸盘组件2b仍处于初始状态，当分裂后的电池片与剩余的电池片拉开一定距离后，第一驱动轴53才进入第二个第一滑槽521-2的第一斜槽521b中并沿第一斜槽521b滑动，从而驱使活动吸盘组件2b转动以分裂电池片，此过程中，第一个第一滑槽521-1中的第一驱动轴53还位于第一斜槽521b中，第一个第二滑槽522-1中的第二驱动轴6位于第二斜槽522b中，因此，在第二个第一滑槽521-2中的第一驱动轴53带动活动吸盘组件2b翻转裂片的过程中，位于第一个第二滑槽522-1中的第二驱动轴6还驱使安装部3带动活动吸盘组件2b滑动，依此类推。
多个安装部3沿水平方向并排设置，多个第二滑槽522沿着垂直于第二直槽522a的方向排布，且自驱动板52的一侧向着另一侧的方向，第三拐点B1的高度的依次递增，从而当驱动板52滑动时，多个安装部3依次发生沿水平方向的滑动。
驱动板52上还设置有分别与多个第一斜槽521b的上端连通的多个第一复位槽521c，第一复位槽521c沿竖直方向延伸，第一斜槽521b与第一复位槽521c的相交处形成第一滑槽521的第二拐点A2。驱动板52上还设置有分别与多个第二斜槽522b的上端连通的多个第二复位槽522c，第二复位槽522c沿竖直方向延伸，第二复位槽522c与第二斜槽522b的相交处形成第二滑槽522的第四拐点B2。在导向板52上，各个第二拐点A2距离基座1的底部的高度相同，各个第四拐点B2距离基座1的底部的高度相同，这样，当将电池片全部分裂后，每个第一滑槽521中的第一驱动轴53同时从第一斜槽521b中经第二拐点A2进入第一复位槽521c中，与此同时，每个第二滑槽522中的第二驱动轴6也同时从第二斜槽522b中经第四拐点B2进入第二复位槽522c中，此过程中，驱使各活动吸盘组件2b同时反向翻转复位到初始状态。
该电池片裂片装置还包括当驱动板52在基座1上上下滑动时提供导向的第一导向机构，第一导向机构包括第一滑轨71和第一滑块72，第一滑轨71固定设置在基座1上，且沿上下方向延伸，第一滑块72能够沿第一滑轨71的长度延伸方向滑动地设置在第一滑轨71上，驱动板52固定设置在第一滑块72上。
该电池片裂片装置还包括当安装部3在基座1上水平滑动时提供导向的第二导向机构，第二导向机构包括第二滑轨81和第二滑块82，第二滑轨81固定设置在基座1上，且沿水平方向延伸，第二滑块82能够沿第二滑轨81的长度延伸方向滑动地设置在第二滑轨81上，第二滑块82与安装部3一一对应设置，每组安装部3均固定设置在一组第二滑块82上。
以下具体介绍一下该电池片裂片装置的工作原理：
(1)首先将电池片放置在吸盘组件2上，放置电池片时，使电池片上的分裂缝分别处于相邻两个吸盘组件2之间，开启真空组件，使电池片吸附在吸盘组件2上，此时，各第一驱动轴53均位于第一直槽521a中，各第二驱动轴6均位于第二直槽522a中，如图5和图6所示；
(2)启动动力装置51，驱动驱动板52相对基座1向下滑动，直至位于第一个第一滑槽521-1中的第一驱动轴53经过第一拐点A1，如图7所示，当第一驱动轴53进入到第一斜槽521b中沿第一斜槽521b滑动时，使得第一驱动轴53带动与其相连接的活动吸盘组件2b绕 转轴4相对安装部3转动，活动吸盘组件2b转动的过程中，使吸附在其上面的电池片与其余的电池片逐渐分裂，直至将第一片电池片完全分裂；
在此过程中，除第一个第一滑槽521-1中的第一驱动轴53外，其余第一驱动轴53均位于第一滑槽521的下部的第一直槽521a中，第二驱动轴6均位于第二滑槽522的下部的第二直槽522a中；
(3)通过动力装置51使驱动板52继续相对基座1向下滑动，直至位于第一个第二滑槽522-1中的第二驱动轴6经过第三拐点B1，如图8所示，当第二驱动轴6进入到第二斜槽522b中并沿第二斜槽522b滑动时，使得第二驱动轴6带动与其相连接的安装部3相对基座1向前滑动，活动吸盘组件2b同步向前滑动，从而拉开分裂后的电池片与剩余的电池片之间的距离；
在此过程中，第一个第一滑槽521-1中的第一驱动轴53仍处于第一斜槽521b中，除第一个第一滑槽521-1中的第一驱动轴53外，其余第一驱动轴53仍均位于第一滑槽521的下部的第一直槽521a中，除第一个第二滑槽522-1中的第二驱动轴6外，其余第二驱动轴6均位于第二滑槽522的下部的第二直槽522a中；
(4)依次顺序重复步骤(2)和步骤(3)，当第一驱动轴53依次进入到第二个第一滑槽521-2、第三个第一滑槽521-3……的中的第一斜槽521b中驱使活动吸盘组件2b翻转分裂电池片的过程中，当一根第一驱动轴53带动一组活动吸盘组件2b相对安装部3转动裂片的过程中，位于其前部的第一驱动轴53均位于第一斜槽521b中，位于其后部的第一驱动轴53均位于下部的第一直槽521a中，位于其前部的第二驱动轴6均位于第二斜槽522b中，位于其后部的第二驱动轴6及与其位于同一安装部3上的第二驱动轴6均位于下部的第一直槽521a中，直至将电池片逐片顺序分裂；
(5)当电池片全部分裂后，且位于最后一个第二滑槽522中的第二驱动轴6驱使与其相连接的安装部3带动活动吸盘组件2b滑动一定距离后，每个第一滑槽521中的第一驱动轴53同时由第一斜槽521b经第二拐点A2进入位于其上方的第一复位槽521c中，同步地，每个第二滑槽522中的第二驱动轴6也同时由第二斜槽522b经第四拐点B2进入位于其上方的第二复位槽522c中，如图9所示，此过程同时使得各活动吸盘组件2b反向翻转复位到初始状态；
(6)在所有活动吸盘组件2b反向翻转复位后，取下各吸盘组件2上的电池片，至此完成该裂片装置分裂电池片的操作。
通过该电池片裂片装置，可使电池片逐片顺序自动分裂，整个过程中无需人工操 作，可降低电池片分裂过程中的碎裂或破损发生的几率，而且可提高裂片的生产效率，从而使得该电池片裂片装置可满足大规模产能的需求。
另外，该电池片裂片装置还可应用于全自动裂片机中，同样不但可以大大提高生产效率，同时可以降低裂片工序中电池片的碎裂和损伤。
