本申请要求于2020年2月13日提交的韩国专利申请第10-2020-0017844号的优先权的权益，通过引用将上述专利申请整体结合在此。
技术领域
本发明涉及一种按压二次电池的设备和方法。
背景技术
通常，与不可充电的一次电池不同，二次电池(secondary battery)是指可充电和放电的电池。二次电池正广泛用在诸如移动电话、笔记本电脑和便携式摄像机之类的高科技电子领域中。
二次电池分为罐型二次电池和袋型二次电池，袋型二次电池包括电极组件、电解质、以及容纳电极组件和电解质的袋。此外，电极组件具有电极和隔膜交替堆叠的结构。此外，袋包括容纳电极组件的容纳部和将容纳部密封的密封部。
此外，二次电池被以均匀的压力按压，以提高性能并延长其寿命。在此，二次电池具有其中袋的密封部因袋内部产生的气体压力而排气(vent)的问题。
发明内容
技术问题
发明了本发明来解决上述问题，本发明的目的是提供一种按压二次电池的设备和方法，其中当按压二次电池时，袋中包括的密封部被一起按压，以防止密封部因袋中包括的容纳部中产生的气体压力而排气，从而稳定地按压二次电池，以提高性能并延长其寿命。
技术方案
为实现上述目的，根据本发明的按压二次电池的设备包括：其上放置包括电极组件和袋的二次电池的放置构件；和配置为按压被放置在所述放置构件上的所述二次电池的按压构件，其中所述按压构件包括：容纳部按压夹具，所述容纳部按压夹具配置为按压被放置在所述放置构件上的所述二次电池的所述袋中的、容纳所述电极组件的所述袋的容纳部；和密封部按压夹具，所述密封部按压夹具配置为按压被放置在所述放置构件上的所述二次电池的所述袋中的、沿所述容纳部的边缘表面形成的密封部，其中所述密封部按压夹具结合至所述容纳部按压夹具的与所述密封部对应的表面，以通过从所述容纳部按压夹具传递的按压力按压所述密封部。
所述密封部按压夹具可以是通过组装具有与所述密封部对应的面积的多个按压块形成的。

具体实施方式
下文中，将参照附图以本发明所属领域的普通技术人员可容易实施本发明的技术构思的方式详细描述本发明的实施方式。然而，本发明可以以不同的形式实施，不应被解释为限于在此阐述的实施方式。在附图中，为了清楚起见，将省略对于描述本发明来说任何不必要的内容，此外，附图中相同的参考标记表示相同的元件。
[根据本发明的二次电池]
如图1中所示，根据本发明的二次电池10包括电极组件11、容纳电极组件11的袋12、以及电极引线13，电极引线13与电极组件11连接并且电极引线13的前端引出到袋之外。
电极引线13具有电极和隔膜交替堆叠的结构，袋12包括容纳电极组件11的容纳部12a和沿容纳部12a的边缘表面设置以将容纳部12a密封的密封部12b。
以均匀的压力按压具有上述结构的二次电池10，以提高电池性能并延长其寿命。在此，使用根据本申请第一实施方式的按压设备。特别是，根据本申请第一实施方式的按压设备可一起按压袋12的容纳部12a和密封部12b。因而，当按压二次电池时，可防止密封部12b排气，因而可以以均匀的压力按压二次电池10，以提高电池性能和寿命。
下文中，将详细描述根据本申请第一实施方式的按压二次电池的设备。
[根据本发明第一实施方式的按压二次电池的设备]
如图1至图5中所示，根据本发明第一实施方式的按压二次电池的设备100包括：其上放置包括电极组件11和袋12的二次电池10的放置构件110；和按压构件120，按压构件120设置成能够朝向被放置在放置构件110上的二次电池10移动，从而按压被放置在放置构件110上的二次电池10。
在此，按压构件120可一起按压袋12的容纳部12a和密封部12b，以防止密封部12b因容纳部12a中产生的气体压力而排气(vent)。就是说，按压构件120可按压密封部12b，以增加密封部12b的密封力，从而防止密封部12b因容纳部12a中产生的气体压力而排气(vent)。
例如，按压构件120包括：容纳部按压夹具121，容纳部按压夹具121按压被放置在放置构件110上的二次电池10的袋12中的、容纳了电极组件11的袋12的容纳部12a；和密封部按压夹具122，密封部按压夹具122按压被放置在放置构件110上的二次电池10的袋12中的、沿容纳部12a的边缘表面形成的密封部12b。
因而，按压构件120可通过容纳部按压夹具121和密封部按压夹具122一起按压袋12的容纳部12a和密封部12b，以增加密封部12b的密封力，从而防止密封部12b因容纳部12a中产生的气体压力而排气。
密封部按压夹具122结合至容纳部按压夹具121的与密封部12b对应的表面。因而，密封部按压夹具122可通过从容纳部按压夹具121传递的按压力按压密封部12b。
通过组装具有与密封部12b对应的面积的多个按压块来形成密封部按压夹具122。就是说，多个按压块在竖直方向上结合的同时组装成密封部按压夹具122，如图3中所示。因而，可仅更换被损坏或变形的按压块以重复使用，特别是，可根据密封部12b的高度来调节密封部按压夹具122的高度，以增加兼容性。
就是说，多个按压块可被调节为具有与密封部12b相同的高度，可被调节为具有比密封部12b的高度小的高度，或者可被调节为具有比密封部12b的高度大的高度。
多个按压块具有包括彼此结合的凹槽和突起的乐高积木的形式，以提高组装和拆卸的便利性。就是说，在一个按压块的结合表面中形成结合凹槽，并且在另一个按压块的结合表面中形成与该结合凹槽结合的结合突起。结合凹槽和结合突起彼此结合。在此，多个组装的按压块可通过粘合剂123粘附，从而不容易分离。
多个按压块包括：与容纳部按压夹具121结合的第一按压块122a、按压密封部12b的第二按压块122b、以及设置在第一按压块122a与第二按压块122b之间的一个或更多个第三按压块122c。就是说，参照图3，在多个按压块中，第一按压块122a、一个或更多个第三按压块122c、以及第二按压块122b依次在竖直方向上彼此结合。
在此，第一按压块122a和第二按压块122b的每一个具有比第三按压块122c的刚性大的刚性。因而，第一按压块122a可有效地结合至容纳部按压夹具121，可通过第二按压块122b有效地按压密封部12b，并且可通过一个或更多个第三按压块122c有效地接收从第一按压块122a或第二按压块122b传递的按压力，以保持均匀的按压力。
特别是，第三按压块122c可由作为具有弹性恢复力的材料的合成树脂制成，从而有效地接收从第一按压块122a或第二按压块122b传递的按压力。
密封部按压夹具122可拆卸地结合至容纳部按压夹具121。就是说，当穿过形成在容纳部按压夹具121中的长形孔121a的螺栓121b结合至密封部按压夹具122时，密封部按压夹具122和容纳部按压夹具121可彼此结合，当螺栓121b被释放时，密封部按压夹具122和容纳部按压夹具121可彼此分离。
密封部按压夹具122可结合成能够在朝向容纳部按压夹具121的中心的方向或者与容纳部按压夹具121的中心相反的方向上调节位置。就是说，形成在容纳部按压夹具121中的长形孔121a可在朝向容纳部按压夹具121的中心的方向上较长地形成，当螺栓121b在长形孔121a内移动时，密封部按压夹具122可与螺栓121b互锁地在朝向容纳部按压夹具121的中心的方向或者与容纳部按压夹具121的中心相反的方向上移动，从而调节密封部按压夹具122的位置。
具有这种结构的密封部按压夹具122可有效地按压袋的密封部，以提高使用的便利性，并且可与各种尺寸的二次电池互换地使用。
因而，根据本发明第一实施方式的按压二次电池的设备100可包括放置构件110和按压构件120，以按压二次电池10中包括的袋12的容纳部12a和密封部12b，以增加密封部12b的密封力，从而防止密封部12b因容纳部12a中产生的气体压力而排气。
下文中，将描述通过使用根据本发明第一实施方式的按压二次电池的设备来按压二次电池的方法。
[根据本发明第一实施方式的按压二次电池的方法]
如图6中所示，根据本发明第一实施方式的按压二次电池的方法包括：放置步骤(S10)，将包括电极组件11和袋12的二次电池10放置在放置构件110上；组装步骤(S15)，组装按压构件120的密封部按压夹具122；结合步骤(S17)，将按压构件120的密封部按压夹具122和容纳部按压夹具121彼此结合；以及按压步骤(S20)，通过按压构件120按压设置在放置构件110上的二次电池10。
放置步骤
在放置步骤(S10)中，将二次电池10放置在放置构件110的顶表面上。
二次电池10包括电极组件11和容纳电极组件11的袋12。在此，袋12包括：形成有容纳电极组件11的容纳空间的壳体、和结合至壳体的盖。在电极组件被容纳到壳体的容纳空间中时，具有这种结构的袋12的壳体与盖结合。因此，可制造出具有容纳电极组件的容纳部12a和将容纳部12a密封的密封部12b的袋12。
将二次电池10放置在放置构件110的顶表面上。在此，二次电池10被放置成使得盖被放置构件110支撑。
组装步骤
在组装步骤(S15)中，制备具有与密封部12b对应的面积的多个按压块，然后将多个按压块依次组装来完成密封部按压夹具122。例如，多个按压块包括第一按压块122a、第二按压块122b、以及一个或更多个第三按压块122c。如上所述制备的第一按压块122a结合至容纳部按压夹具121并且设置在最上端，第二按压块122b配置为按压密封部12b并且设置在最下端，一个或更多个第三按压块122c设置在第一按压块122a与第二按压块122b之间。
在此，第一按压块122a和第二按压块122b的每一个由具有比第三按压块122c的刚性大的刚性的材料制成，因而密封部按压夹具122稳定地结合至容纳部按压夹具121，以稳定地按压密封部12b。此外，第三按压块122c由具有弹性恢复力的材料制成，以弹性地按压密封部12b，从而防止密封部12b损坏。
结合步骤
在结合步骤(S17)中，将密封部按压夹具122结合至容纳部按压夹具121。就是说，在结合步骤(S17)中，将密封部按压夹具122设置在容纳部按压夹具121的与设置在放置构件110上的袋12的密封部12b对应的表面上。接着，螺栓121b穿过形成在容纳部按压夹具121的表面中的长形孔121a，然后结合至密封部按压夹具122。然后，密封部按压夹具122和容纳部按压夹具121彼此结合，以完成按压构件120。
在此，当螺栓121b在长形孔121a内移动时，可调节密封部按压夹具122的位置。
按压步骤
在按压步骤(S20)中，按压构件120朝向被放置在放置构件110上的二次电池10下降，以按压被放置在放置构件110上的二次电池10。就是说，按压构件120包括：第一按压工序，通过按压构件120的容纳部按压夹具121按压被放置在放置构件110上的二次电池10的袋12中的、容纳电极组件11的袋12的容纳部12a；和第二按压工序，通过按压构件120的密封部按压夹具122按压被放置在放置构件110上的二次电池10的袋12中的、沿容纳部12a的边缘表面形成的密封部12b。
密封部按压夹具122可与密封部12b对应地结合至容纳部按压夹具121，以利用从容纳部按压夹具121传递的按压力按压密封部12b，从而显著提高密封部12b的密封力，因此防止密封部12b因容纳部12a中产生的气体压力而排气。
如图7中所示，在按压步骤(S20)中，在按压密封部12b之前，将具有弹性的弹性构件130结合至容纳部按压夹具121的按压袋12的容纳部12a的按压表面，以弹性地按压袋的容纳部12a，从而防止容纳部12a被损坏和留痕。
在按压步骤(S20)中，弹性构件130可附接至袋的容纳部或密封部，从而更弹性地按压袋的容纳部和密封部。
因此，在根据本发明第一实施方式的按压二次电池的方法中，当按压二次电池时，可一起按压袋的容纳部和密封部，以增加密封部的密封力，从而防止密封部排气。
下文中，在本发明其他实施方式的描述中，对于具有与上述实施方式相同构造的组件标记使用相同的组件标记，并且将省略重复的描述。
[根据本发明第二实施方式的按压二次电池的设备]
如图8中所示，根据本发明第二实施方式的按压二次电池的设备100包括按压密封部12b的密封部按压夹具122。密封部按压夹具122包括第一按压块122a、第二按压块122b、以及一个或更多个第三按压块122c。
在此，可在第二按压块的按压密封部12b的按压表面上形成多个按压突起122b-1，从而以多段按压密封部12b，因而可通过多个按压突起122b-1将密封部12b以多段密封，以显著防止密封部12b排气。
[根据本发明第三实施方式的按压二次电池的设备]
如图9和图10中所示，根据本发明第三实施方式的按压二次电池的设备100包括按压构件120’，按压构件120’包括密封部按压夹具122’。密封部按压夹具122’包括第一按压块122a、第二按压块122b’、以及一个或更多个第三按压块122c。
在此，按压密封部12b的第二按压块122b’具有大于或小于第一按压块122a和第三按压块122c的每一个的宽度的宽度。因而，可根据密封部12b的宽度仅更换第二按压块122b’来重复使用。结果，由于不必更换整个密封部按压夹具122’，所以可提高使用的便利性。
[根据本发明第四实施方式的按压二次电池的设备]
如图11中所示，根据本发明第四实施方式的按压二次电池的设备100包括按压构件120A，按压构件120A包括容纳部按压夹具121和密封部按压夹具122A。密封部按压夹具122A可具有“ㄈ”形，以同时按压设置于二次电池10中的袋12之中的除引出电极引线13的一个表面之外的三个表面，因而可稳定地按压袋的密封部。
[根据本发明第五实施方式的按压二次电池的设备]
如图12中所示，根据本发明第五实施方式的按压二次电池的设备100包括按压构件120B，按压构件120B包括容纳部按压夹具121和密封部按压夹具122B。密封部按压夹具122B可具有“ロ”形，以同时按压设置于二次电池10中的袋12之中的包括引出电极引线13的一个表面在内的四个表面，因而可稳定地按压袋的密封部。
因此，本发明的范围由所附权利要求书限定，而不是由前面的描述和在此描述的示例性实施方式限定。在本发明的权利要求的等同含义内以及在权利要求内进行的各种修改应当认为在本发明的范围内。
