Description

袋状壳体密封装置
技术领域
本公开涉及袋状壳体密封装置，并且更具体地，涉及用于密封电池单元的袋状壳体的袋状梯台(terrace)的袋状壳体密封装置。
背景技术
高度适用于各种产品并且表现出诸如能量密度高等这样的优异电性能的二次电池通常不仅用于便携式设备，而且用于由电能源驱动的电动车辆(EV)或混合电动车辆(HEV)。二次电池作为提高能源效率和环境友好性的新能源受到关注，这是因为能够极大地减少化石燃料的使用并且在能量消耗期间不会产生副产物。
当前广泛使用的二次电池包括锂离子电池、锂聚合物电池、镍镉电池、镍氢电池、镍锌电池等。单位二次电池单元(即，单位电池单元)的工作电压为约2.5V至4.6V。因此，如果需要更高的输出电压，则可以将多个电池单元串联连接以配置电池组。另外，根据电池组所需的充电/放电容量，多个电池单元可以被并联连接以配置电池组。因此，可以根据所需的输出电压或所需的充电/放电容量来不同地设置电池组中所包括的电池单元的数量。
此外，当多个电池单元被串联或并联连接以配置电池组时，通常首先配置由至少一个电池单元组成的电池模块，然后通过使用至少一个电池模块并添加其它部件来配置电池组。这里，配置电池模块或电池组的电池单元可以是可以容易彼此堆叠的袋型二次电池。
参照图1至图3，作为袋型二次电池的传统电池单元1包括电极组件10、用于封装电极组件10的袋状壳体50以及从袋状壳体50突出并电连接到电极组件10的一对电极引线70。
这里，袋状壳体50包括：袋状主体52，其具有用于容纳电极组件10的容纳空间；以及袋状梯台56，其从袋状主体52延伸并通过使用用于密封袋状壳体50的袋状壳体密封装置5进行热熔。
传统袋状密封装置5被配置为包括一对密封夹具(jig)，以密封袋状壳体50的四个表面或三个表面。近年来，在确保电池单元1的容量和空间利用率方面，密封袋状主体52的四个侧表面当中的仅三个表面的三面密封正在增多。传统袋状密封装置5密封袋状壳体50，同时一对密封夹具按压袋状梯台56并且使袋状梯台56热熔。
然而，当通过使用传统袋状密封装置5密封电池单元1的袋状壳体50时，如图3所示，袋状梯台56的至少一个端部由于按压而被压缩，因此在水平方向上从袋状主体52的未被密封的一个侧表面突出预定距离b。
因为袋状梯台56的突出部分b以所谓的蝙蝠耳的形式设置，所以当配置电池模块或电池组时，它成为形成不必要的死区的因素，从而降低能量密度或使组装过程的效率劣化。
实用新型内容
技术问题
本公开旨在提供一种可以在密封电池单元的袋状壳体时防止袋状梯台的端部朝向非密封表面突出的袋状壳体密封装置。
另外，本公开旨在提供一种可以增加电池单元的能量密度的袋状壳体密封装置。

所述防梯台突出单元可以包括：防突出引导凸起，该防突出引导凸起被配置为从任一密封夹具的按压表面倾斜突出；以及防突出引导凹槽，该防突出引导凹槽具有与所述防突出引导凸起对应的形状，并且被形成在另一密封夹具的按压表面处。
当所述一对密封夹具按压所述袋状梯台并且使所述袋状梯台热熔时，所述防突出引导凸起和所述防突出引导凹槽可以以所述袋状梯台的端部夹在所述防突出引导凸起和所述防突出引导凹槽之间的方式接合，同时使所述袋状梯台的所述端部在所述袋状主体的向上方向和向下方向中的至少一个方向上弯曲。

在下文中，将基于袋状壳体密封装置100执行在确保电池单元1的容量和空间利用率方面密封袋状主体52的四个侧表面当中的仅三个表面的三面密封的情况来描述该实施方式。
袋状壳体密封装置100可以包括密封夹具110、130和防梯台突出单元150、160。除了这些部件之外，袋状壳体密封装置100还可以包括用于密封袋状壳体50的其它部件，例如夹具升降单元和夹具驱动单元。
密封夹具110、130可以在袋状壳体50的上下方向上按压袋状梯台56并且使袋状梯台56热熔，使得袋状壳体50被密封。
密封夹具110、130可以被成对设置。一对密封夹具110、130可以具有在袋状梯台56的按压方向上按压袋状梯台56的按压表面115、135。
防梯台突出单元150、160形成在一对密封夹具110、130的按压表面115、135处。当袋状梯台56由于压力而热熔时，防梯台突出单元150、160可以防止袋状梯台56的端部在袋状主体52的水平方向上从袋状主体52突出。防梯台突出单元150、160可以分别一体地形成在按压表面115、135处。
防梯台突出单元150、160可以被成对设置。一对防梯台突出单元150、160可以包括防突出引导凸起150和防突出引导凹槽160。
防突出引导凸起150可以形成在任一密封夹具110处，而防突出引导凹槽160可以形成在另一个密封夹具130处。例如，防突出引导凸起150可以形成在一对密封夹具110、130当中的被设置在上侧的密封夹具110处，而防突出引导凹槽160可以形成在所述一对密封夹具110、130当中的被设置在下侧的密封夹具130处。相反，防突出引导凹槽形成在被设置在上侧的密封夹具处而防突出引导凸起形成在被设置在下侧的密封夹具处也是可以的。
防突出引导凸起150可以从任一密封夹具110的按压表面115倾斜突出。防突出引导凸起150被形成具有大致三角形形状并且可以被设置在任一密封夹具110的按压表面115的一个端部处。
当一对密封夹具110、130按压袋状梯台56并且使袋状梯台56热熔时，防突出引导凸起150可以与防突出引导凹槽160接合，袋状梯台56的端部夹在防突出引导凹槽160和防突出引导凸起150之间，以使袋状梯台56的该端部在袋状主体52的向上方向和向下方向中的至少一个方向上弯曲。
防突出引导凸起150可以包括第一倾斜表面152、第二倾斜表面154和引导表面156。
第一倾斜表面152可以从任一密封夹具110的按压表面115向下突出。这里，当一对密封夹具110、130按压袋状壳体50时，第一倾斜表面152可以在电池单元1的袋状壳体50的垂直方向上突出不超过袋状主体52的底部的高度。如果第一倾斜表面152可能突出超过袋状主体52的底部，则在袋状壳体50被密封之后，袋状梯台56会在袋状壳体50的垂直方向上从袋状主体52的底部突出。
第二倾斜表面154可以从第一倾斜表面152向上倾斜突出。第二倾斜表面154可以被形成为比第一倾斜表面152长，以确保弯曲空间。
第二倾斜表面154可以在电池单元1的袋状壳体50的垂直方向上突出不超过袋状主体52的顶部的高度。如果第二倾斜表面154可能进一步地突出，则在袋状壳体50被密封之后，袋状梯台56会在袋状壳体50的垂直方向上从袋状主体52的顶部突出。
引导表面156可以沿着任一密封夹具110的水平方向从第二倾斜表面154延伸。当袋状壳体50被密封时，如果袋状梯台56移到第二倾斜表面154之外，则引导表面156可以防止袋状梯台56从袋状主体52的顶部突出。
此外，如果袋状梯台56移到第二倾斜表面154之外，则引导表面156可以附加地防止袋状梯台56在袋状壳体50的水平方向上从袋状主体52突出。
防突出引导凹槽160具有与防突出引导凸起150对应的形状，并且可以被形成在另一密封夹具130的按压表面135处。
防突出引导凹槽160可以具有与防突出引导凸起150对应的三角形形状，并且可以被设置在另一密封夹具130的按压表面135的一个端部处。
当一对密封夹具110、130按压袋状梯台56并且使袋状梯台56热熔时，防突出引导凹槽160与防突出引导凸起150接合，袋状梯台56的端部夹在防突出引导凹槽160和防突出引导凸起150之间，并且防突出引导凹槽160使袋状主体52的该端部在袋状主体52的向上方向和向下方向中的至少一个方向上弯曲。
防突出引导凹槽160可以包括第一倾斜表面162、第二倾斜表面164和引导表面166。
第一倾斜表面162从另一密封夹具130的按压表面135向下倾斜，并且可以被形成于在另一密封夹具130的垂直方向上与防突出引导凸起150的第一倾斜表面152对应的位置处。
第一倾斜表面162被形成为具有当一对密封夹具110、130按压袋状壳体50时在电池单元1的袋状壳体50的垂直方向上不超过袋状主体52的底部的深度。如果第一倾斜表面162具有更大的深度，则在袋状壳体50被密封之后，袋状梯台56会在袋状壳体50的垂直方向上从袋状主体52的底部突出。
第二倾斜表面164从第一倾斜表面162向上倾斜突出，并且可以被形成于在另一密封夹具130的垂直方向上与防突出引导凸起150的第二倾斜表面154对应的位置处。第二倾斜表面164可以被形成为比第一倾斜表面162长，以确保弯曲空间。
第二倾斜表面164可以在电池单元1的袋状壳体50的垂直方向上突出不超过袋状主体52的顶部的高度。如果第二倾斜表面164进一步地突出，则在袋状壳体50被密封之后，袋状梯台56会在袋状壳体50的垂直方向上从袋状主体52的顶部突出。
引导表面166沿着任一密封夹具130的水平方向从第二倾斜表面164延伸，并且可以被形成在与防突出引导凸起150的引导表面156对应的位置处。
当袋状壳体50被密封时，如果袋状梯台56移到第二倾斜表面164之外，则引导表面166可以与防突出引导凸起150的引导表面156一起防止袋状梯台56从袋状主体52的顶部突出。
此外，如果袋状梯台56移到第二倾斜表面164之外，则引导表面166可以与防突出引导凸起150的引导表面156一起附加地防止袋状壳体50在水平方向上从袋状主体52突出。
图6和图7是用于示出根据本公开的不同实施方式的袋状壳体密封装置的防梯台突出单元的图。
参照图6，防梯台突出单元180、185可以包括防突出引导凸起180和防突出引导凹槽185。不同于上述实施方式，防突出引导凸起180和防突出引导凹槽185是方形形状的。
参照图7，防梯台突出单元190、195可以包括防突出引导凸起190和防突出引导凹槽195。不同于上述实施方式，防突出引导凸起190和防突出引导凹槽195是半圆形状的。
因此，防梯台突出单元的形状可以是三角形、方形或半圆形，只要它能够防止袋状梯台56突出即可。另外，本公开的实施方式不限于这样的形状，并且能够防止袋状梯台56突出的其它形状(例如，梯形形状等)也是可以的。
在下文中，将更详细地描述根据本公开的实施方式的袋状壳体密封装置100的详细操作。
图8至图12是用于示出图4的袋状壳体密封装置的操作的图。
参照图8和图9，袋状壳体密封装置100可以借助于一对密封夹具110、130按压袋状梯台56，以密封电池单元1的袋状壳体50。
参照图10至图12，此时，防梯台突出单元150、160可以使袋状梯台56的端部弯曲。因此，袋状梯台56的端部可以被设置成在袋状壳体50的水平方向上不超过袋状主体52的端部。具体地，基于袋状主体52未被密封的袋状主体52的非密封表面，袋状梯台56的端部可以由于弯曲而被设置为在袋状壳体50的水平方向上相对于袋状主体52的非密封表面(在图中的左侧)向内达预定距离d。
因此，根据本实施方式的袋状壳体密封装置100可以在电池单元1的袋状壳体50被密封时防止袋状梯台56的端部朝向非密封表面侧突出。
因此，因为不会形成传统地由突出的毛刺导致的死区，所以根据本实施方式的袋状壳体密封装置100可以显著地增加电池单元1的能量密度。
此外，根据本实施方式的袋状壳体密封装置100不会导致可能传统地由突出的毛刺产生的对相邻部件等的干扰，因此能够极大地提高电池单元1的组装过程的效率。
虽然已经示出并描述了本公开的实施方式，但是应当理解，本公开不限于所描述的特定实施方式，并且本领域技术人员能够在本公开的范围内进行各种改变和修改，并且从本公开的技术思想和观点来看，这些修改不应该被单独理解。
本申请要求于2017年12月21日在韩国提交的韩国专利申请No.10-2017-0177307的优先权，该韩国专利申请的公开内容通过引用并入到本文中。
