本发明的电池取料装置可用于电池3的上料或下料。
电池3可为软包锂离子电池。电池3包括电极组件和包装袋，电极组件 封装在包装袋内。电极组件包括正极片、负极片以及将正极片和负极片隔开的隔膜，正极片、隔膜及负极片可卷绕为扁平状。包装袋可由铝塑膜制成。其中，图4为电池在成型过程中的某个形态。
参照图1至图3，本发明的电池取料装置包括抓取机构1和防护机构2。
抓取机构1包括基板11、吸盘12、连接件13和动力组件14。基板11可为平板状。吸盘12设置于基板11的下侧且通过连接件13固定到基板11。连接件13可与外部的真空设备相连。动力组件14位于基板11上侧且与基板11相连，动力组件14用于驱动基板11移动。
吸盘12用于抓取电池3。具体地，当吸盘12与电池3接触时，真空设备启动并抽真空，使吸盘12内产生负气压，从而将电池3吸住，然后动力组件14通过基板11将电池3移动到另一个工序。当电池3移动到目的地时，真空设备向吸盘12内充气，使吸盘12内的负气压变成零气压或正气压，吸盘12就与电池3脱离。
动力组件14可包括机架、电机、螺杆、滑块及连接板，机架用于连接到外部的移动平台，螺杆设置于机架且上下延伸，电机固定于机架且与螺杆相连，滑块与螺杆螺纹连接并上下滑动设置，连接板连接滑块和基板11。电机正反转时，螺杆带动滑块上下移动，对应地，基板11也会随着滑块上下移动。当然，动力组件14也可为能够带动基板11在三维空间内移动的结构。
防护机构2包括驱动器21、传动支架22以及支撑轴23，驱动器21设置于基板11上侧，传动支架22的一端连接于驱动器21，支撑轴23转动地连接于传动支架22的另一端。驱动器21可为旋转气缸。
传动支架22为驱动器21和支撑轴23之间的传动件，因此，当驱动器21带动传动支架22转动时，支撑轴23会沿着圆形的轨迹运动。支撑轴23设置为能够在传动支架22转动时移动到吸盘12的下侧，也就是说，支撑轴23的部分运动轨迹位于吸盘12的下侧。优选地，支撑轴23的部分运动轨迹还位于基板11沿横向X的外侧。
下面详述本发明的电池取料装置的工作过程：
1)需要抓取电池3时，外部的移动平台将电池取料装置移动到电池3的上侧。此时，参照图2，防护机构2处于张开状态(例如，支撑轴23可在驱动器21和传动支架22的带动下移动到基板11的外侧，支撑轴23的位置 可高于吸盘12)。
2)动力组件14的电机带动螺杆旋转，螺杆通过滑块和连接板带动基板11向下移动，当吸盘12接触电池3的上表面时，电机停止工作。然后，真空设备启动并对吸盘12抽真空，从而吸住电池3。
3)动力组件14的电机带动螺杆旋转，螺杆通过滑块和连接板带动基板11向上移动，当基板11移动到设定高度时，电机停止工作。
4)驱动器21工作并带动传动支架22转动，当支撑轴23移动到电池3的下侧并接触电池3的下表面时，驱动器21停止工作。支撑轴23可以从下侧支撑电池3。
5)外部移动平台将电池取料装置移动到另一个工序。当电池取料装置移动到目标位置时，驱动器21工作并带动传动支架22转动，从而将支撑轴23移动到基板11沿横向X的外侧。
6)动力组件14的电机带动螺杆旋转，螺杆通过滑块和连接板带动基板11向下移动，当电池3到达设定位置时，真空设备启动并对吸盘12充气，从而释放电池3。
7)动力组件14的电机带动螺杆旋转，螺杆通过滑块和连接板带动基板11向上移动，当基板11移动到设定高度时，电机停止工作。外部的移动平台带动电池取料装置进入下一个循环。
在本申请的电池取料装置中，即使出现断电等意外情况(真空设备停止，吸盘12无法吸住电池3)，支撑轴23也可以从下侧支撑电池3，防止电池3掉落，降低安全隐患，保证电池质量。
驱动器21为旋转气缸，气缸动作为瞬间刚性动作，冲击力大，如果采用板状或其它形状的支撑件，那么所述支撑件会冲击电池3且无法缓冲，导致电池3被刮伤；同时，当电池3的规格、形态改变时，支撑件的棱边可能会冲击电池3，导致电池3被刮伤。而在本申请中，支撑轴23的表面为圆弧面，且支撑轴23转动设置，因此，支撑轴23移动到电池3的下侧时，可以通过转动减小对电池3的冲击力，防止电池3被刮伤。另外，支撑轴23的表面为圆弧面，不存在尖锐的棱边，即使电池3的规格、形态改变，也不易刮伤电池，因此，本申请的电池取料装置具有较好的通用性。
如果防护机构2整体设置在基板11的下侧，那么会增大电池取料装置 的整体高度，增大电池取料装置的运动空间，降低工作效率。而在本申请中，驱动器21设置于基板11的上侧，与动力组件14占用的空间重叠，不会额外增大电池取料装置的整体高度。同时，参照图2，当防护机构2处于张开状态时，防护机构2整体可以高于吸盘12，从而减小电池取料装置的整体高度。
支撑轴23的表面包覆有塑胶。塑胶的材质较软，可以减小对电池3的冲击力，避免电池3被刮伤。
出现断电等意外情况，支撑轴23可以从下侧支撑电池3；但是，如果电池取料装置出现震动，电池3可能会沿着支撑轴23的延伸方向滑动，也会存在掉落风险。优选地，防护机构2还包括挡板24，挡板24固定于传动支架22且位于支撑轴23沿延伸方向的外侧。挡板24可以限制电池3沿支撑轴23延伸方向的滑动，避免电池3掉落。
在电池3的某些生产工序中，电池3需要相对于水平面倾斜放置，对应地，基板11、吸盘12以及支撑轴23也需要对应地倾斜。由于支撑轴23相对于水平面倾斜，因此，当出现断电等意外情况时，电池3可能会沿着支撑轴23的延伸方向朝较低的一侧滑动；优选地，挡板24设置于支撑轴23在延伸方向上较低的一侧，这样可以限制电池3的滑动，避免电池3掉落。
防护机构2为两组且分别设置于基板11沿横向X的两侧，支撑轴23沿纵向Y延伸。两组防护机构2的支撑轴23可以改善电池3受力的均匀性，提高防护效果。
防护机构2还包括固定于基板11上侧的转接板25，且转接板25的一端延伸到基板11的外侧；驱动器21固定于转接板25的延伸到基板11外侧的部分。转接板25可以增大驱动器21与吸盘13的距离，为支撑轴23提供更大的运动空间，避免支撑轴23在运动的过程中与电池3干涉。
传动支架22包括传动杆221，传动杆221包括第一杆部221A和第二杆部221B，第一杆部221A的一端连接于驱动器21，第二杆部221B的一端连接于第一杆部221A的另一端且相对于第一杆部221A弯折。也就是说，传动杆221大体弯折为L形。支撑轴23可沿垂直于传动杆221的方向延伸，且支撑轴23转动地连接于第二杆部221B的另一端。
L形的传动杆221可以在实现支撑轴23转动的同时，避免传动杆221 与基板11、转接板25、电池3等部件干涉。
传动支架22还包括安装块222，固定于第二杆部221B的远离第一杆部221A的一端；支撑轴23转动地连接于安装块222。安装块222和支撑轴23的延伸方向大体相同。支撑轴23的两端可通过轴承连接到安装块222。
传动杆221为两个且沿纵向Y布置，安装块222可同时连接于两个传动杆221。两个传动杆221可以提高传动支架22的整体强度，能够向支撑轴23提供足够的支撑力。
传动支架22还包括连杆223，连杆223沿纵向Y延伸并连接所述两个传动杆221。连杆223可以提高两个传动杆221之间的连接强度，保证两个传动杆221同步转动。
本申请的传动支架22由多个杆件组成的框架结构，重量较小，这样可以减小载荷，提升反应效率。
本申请还提供了一种电池取料方法，其包括步骤：
将抓取机构1的吸盘12移动到电池3的上侧，从而使吸盘12吸住电池3；
抓取机构1带动电池3向上移动，然后将连接于抓取机构1的支撑轴23移动到吸盘12和电池3的下侧，从而使支撑轴23从下侧支撑电池3；
抓取机构1将电池3移动到设定位置的上侧，然后将支撑轴23从电池3的下侧移开；
抓取机构1向下移动电池3，从而将电池3放置到设定位置；
吸盘12将电池3松开。
在本申请的电池取料方法中，即使出现断电等意外情况(真空设备停止，吸盘12无法吸住电池3)，支撑轴23也可以从下侧支撑电池3，防止电池3掉落，降低安全隐患，保证电池质量。
当抓取机构1将电池3移动到设定位置的上侧时，将支撑轴23移动到电池3沿横向X的外侧。优选地，此时支撑轴23的位置可高于吸盘12。
