目前，从市场形势的发展来看，动力电池的应用越加广泛。动力电池不仅被应用于水力、火力、风力和太阳能电站等储能电源系统，而且还被广泛应用于电动自行车、电动摩托车、电动汽车等电动交通工具以及其他领域。随着动力电池应用领域的不断扩大，其市场的需求量也在不断地扩增。
电池单体是组成电池的最小单元，而对于电池单体的结构而言，通常是将电极组件放置于壳体内，并在壳体中填充电解液，以使电极组件与电解液之间充分接触。其中，在电解液的制备过程中，需要将多种溶剂按照预定的配比进行混合，得到最终所需要的电解液。
由于混合形成电解液的溶剂种类有很多，其中还包括一些易燃易爆的危险溶剂，这就使得溶剂备料过程中的安全性显得十分重要。
此外，备料过程中需要计算不同溶剂的重量，以便于将不同溶剂按照预设的比例进行混合。而在此过程中，则会涉及溶剂的储存、转移以及检测。
然而，目前溶剂的备料过程中，通常是将溶剂储存于料筒内，然后通过吸料枪将溶剂通过泵送抽吸的方式转移至计量装置中。这样一来，一方面，料筒内的溶剂在上料过程中处于敞开状态，容易受到空气影响；或者吸料枪在抽出时会带出部分溶剂，导致溶剂挥发。另一方面，采用泵送的方式输送溶剂时，不仅容易导致溶剂在料筒或输料管道中残留部分溶剂，而且当泵送装置出现老化或者其他问题时，还容易导致溶剂泄漏，存在一定的操作风险。
基于以上考虑，为了解决目前溶剂备料过程中溶剂容易出现残留挥发或泄漏等问题，本申请的一个或多个实施例中提供了一种备料装置，能够将储料罐内的目标溶剂通过连接管道转移至计量组件中，然后对目标溶剂的重量进行检测，以便于进行溶剂的混合配料。其中，充气组件能够向储料罐内通入惰性气体，一方面，当目标溶剂储存于储料罐内时，通入的惰性气体能够对储料罐内的目标溶剂形成密封，降低目标溶剂发生挥发的概率。另一方面，向储料罐内持续通入惰性气体还能够对储料罐内的目标溶剂形成气送，将目标溶剂从储料罐内顺利转移至计量组件中，降低储料罐、连接管道内出现溶剂残留或者发生溶剂泄漏的概率。
参阅图1，本申请一实施例提供了一种备料装置100，用于转移目标溶剂，备料装置100包括储料罐10、计量组件20、连接管道30及充气组件40，其中，储料罐10用于储存目标溶剂。计量组件20用于接收来自储料罐10的目标溶剂，并检测所接收的目标溶剂的重量。连接管道30连通于储料罐10与计量组件20之间，用于将目标溶剂由储料罐 10输送至计量组件20。充气组件40与储料罐10连通，并用于向储料罐10内通入惰性气体。
需要说明的是，本申请的备料装置100可以应用于电解液制备过程中各种溶剂的备料过程，其中，备料装置100可以用于转移一些危险溶剂，当然，也可以用于转移其他的普通溶剂。
储料罐10是指，能够用于储存目标溶剂，并对目标溶剂进行上料的结构。储料罐10的内部中空设置，以便于为目标溶剂提供储存空间。计量组件20是指，能够接收由储料罐10上料的目标溶剂，并且能够检测所接收的目标溶剂的重量。由此，可以根据备料的比例向计量组件20内输入一定量的目标溶剂，以便于在后续过程中与其他溶剂进行混合。
连接管道30是指用于将储料罐10与计量组件20内部连通，以使目标溶剂能够经由连接管道30由储料罐10转移至计量组件20中的结构。
充气组件40是指能够向储料罐10内通入惰性气体的结构，具体地，充气组件40可以向储料罐10内通入氮气。其中，充气组件40可以根据需要，在不同时间向储料罐10内通入氮气。
例如，储料罐10在上料之前，首先向其中注入目标溶剂，实现目标溶剂的暂存。当目标溶剂注入完毕之后，可以通过充气组件40向储料罐10内通入氮气，此时氮气对目标溶剂形成氮封，从而能够降低目标溶剂出现挥发或者与空气发生反应的概率。
而在储料罐10向计量组件20中输送目标溶剂的过程中，也可以通过充气组件40持续向储料罐10内通入氮气，此时目标溶剂在氮气的压力作用下经由连接管道30进入计量组件20，从而实现了目标溶剂的转移。在此过程中，氮气不仅能够实现目标溶剂的转移，还能够有效去除储料罐10或连接管道30内的残留目标溶剂，使得目标溶剂的转移更加彻底。此外，通入氮气的气送方式来替代泵送方式，还能够降低发生泄漏的概率。
由此，通过上述结构，一方面，当目标溶剂储存于储料罐10内时，通入的惰性气体能够对储料罐10内的目标溶剂形成密封，降低目标溶剂发生挥发的概率；另一方面，向储料罐10内持续通入惰性气体还能够对储料罐10内的目标溶剂形成气送，将目标溶剂从储料罐10内顺利转移至计量组件20中，降低储料罐10、连接管道30内出现溶剂残留或者发生溶剂泄漏的概率。
在一些实施例中，储料罐10上分别开设有第一连接口(图中未示出)及第二连接口(图中未示出)，第一连接口位于储料罐10的底部，并与连接管道30的一端连接，第 二连接口位于储料罐10的顶部，并与充气组件40连接。
具体地，第一连接口及第二连接口均与储料罐10的内部连通，将第一连接口与连接管道30连接，能够使储料罐10内的目标溶剂及氮气顺利进入连接管道30内，然后经由连接管道30进入计量组件20。将第二连接口与充气组件40连接，则能够使氮气经由第二连接口顺利进入储料罐10内，实现氮封或者实现氮气吹送的目的。
进一步地，第一连接口设置于储料罐10的底部，第二连接口设置于储料罐10的顶部，如此，氮气由第二连接口从上往下的进入储料罐10内，在氮气的压力作用下，储料罐10内的目标溶剂由底部的第一连接口进入连接管道30中。这样一来，不仅能够使得氮气吹送的效果更好，还能够最大程度的减少储料罐10内目标溶剂的残留。
通过上述结构，使得储料罐10内目标溶剂的转移更加彻底，并且还能够提高气送效果。
在一些实施例中，充气组件40包括第一进气管41、第一出气管42及第一控制阀43，第一进气管41及第一出气管42分别与储料罐10连通，第一控制阀43分别设置于第一进气管41及第一出气管42上，并用于控制第一进气管41或第一出气管42的通断。
需要说明的是，第一控制阀43可以设置为两个，并且分别设置于第一进气管41和第一出气管42上。此外，第二连接口也可以设置为两个子口，并且分别与第一进气管41和第一出气管42连通。
其中，第一进气管41可以将氮气输入至储料罐10内，第一出气管42则可以实现储料罐10内的氮气或者其他气体排出。
具体地，在使用过程中，首先开启第一进气管41上的第一控制阀43，并关闭第一出气管42上的第一控制阀43，此时，通过第一进气管41向储料罐10内输入氮气，在氮气的压力作用下将目标溶剂从储料罐10内转移至计量组件20。当计量组件20中目标溶剂的重量达到目标要求时，关闭第一进气管41上的第一控制阀43，并且开启第一出气管42上的第一控制阀43，对备料装置100内部进行卸压，完成目标溶剂的完整上料过程。
通过上述结构，可以实现储料罐10内的通气，从而实现储料罐10内目标溶剂的密封和顺利输送，当目标溶剂输送完毕之后，还可以实现储料罐10内的卸压，实现完整的上料过程。
在一些实施例中，计量组件20包括计量罐21及称重传感器22，计量罐21设置于称重传感器22上，并用于接收目标溶剂，称重传感器22用于检测计量罐21及其内部目标溶剂的总重量。其中，连接管道30连通于储料罐10与计量罐21之间。
具体地，计量罐21的内部中空设置，能够为目标溶剂提供储存空间。将连接管道30连通于储料罐10与计量罐21之间，从而能够将储料罐10内的目标溶剂顺利转移至计量罐21中。
进一步地，计量罐21设置于称重传感器22上，在转移目标溶剂之前，称重传感器22可以得到计量罐21本身的重量。而在转移目标溶剂的过程中，称重传感器22根据变化的重量可以快速得到所转移的目标溶剂的重量，从而能够根据实际生产需要准确地控制转移至计量罐21中的目标溶剂的量，以便于后续与其他溶剂进行混合配比。
通过上述结构，目标溶剂由储料罐10转移至计量罐21的过程中，可以快速得到所转移的目标溶剂的重量，从而能够根据实际需求更好地控制目标溶剂的转移量，提高备料精度。
在一些实施例中，计量罐21的顶部开设第三连接口(图中未示出)，连接管道30背离储料罐10的一端与第三连接口连接。
具体地，第三连接口与计量罐21的内部连通。当连接管道30内的目标溶剂在氮气压力作用下移动时，进入计量罐21之前存在一个爬升的过程，由此，在氮气的压力作用下可以将连接管道30内的目标溶剂更彻底的转移至计量罐21内，减少连接管道30内部目标溶剂的残留量。
通过上述结构，可以使得连接管道30内的目标溶剂更彻底地转移至计量罐21中，减少连接管道30内部目标溶剂的残留量。
在一些实施例中，计量组件20还包括第二进气管23、第二出气管24及第二控制阀25，第二进气管23及第二出气管24分别与计量罐21连通，第二控制阀25分别设置于第二进气管23及第二出气管24上，并用于控制第二进气管23或第二出气管24的通断。
需要说明的是，第二控制阀25可以设置为两个，并且分别设置于第二进气管23和第二出气管24上。其中，第二进气管23可以实现计量罐21内的进气，第二出气管24则可以实现计量罐21内气体的排出。
具体地，在使用过程中，首先开启第一进气管41上的第一控制阀43、第二进气管23上的第二控制阀25和第二出气管24上的第二控制阀25，并且关闭第一出气管42上的第一控制阀43。此时，通过第一进气管41向储料罐10内输入氮气，在氮气的压力作用下将目标溶剂从储料罐10内转移至计量罐21内。当计量罐21中目标溶剂的重量达到目标要求时，关闭第一进气管41上的第一控制阀43，并且开启第一出气管42上的第一控制阀43，对备料装置100内部进行卸压。完成卸压之后，再将第二进气管23上的第二控制阀 25和第二出气管24上的第二控制阀25依次关闭，使得上料动作暂停。
通过上述结构，可以顺利通过惰性气体吹送的方式将储料罐10内的目标溶剂输送至计量罐21内，然后在计量罐21内实现目标溶剂的称重。
在一些实施例中，计量组件20还包括第一压力传感器26，第一压力传感器26设置于计量罐21上，并用于检测计量罐21内的压力。
具体地，在目标溶剂从储料罐10内转移至计量罐21内的过程中，第一压力传感器26能够对计量罐21内的压力进行实时检测，确保计量罐21内压力的稳定，从而使称重传感器22所检测的结果更加准确。
在一些实施例中，备料装置100还包括设置于连接管道30上的过滤器50，过滤器50用于过滤经过连接管道30的目标溶剂。
具体地，过滤器50可以但不限于设置为微孔过滤器50。当目标溶剂经由连接管道30进入计量罐21中时，过滤器50能够对连接管道30内的目标溶剂进行过滤，筛除其中的一些杂质，使得进入计量罐21中的目标溶剂更加干净。

具体地，当第二压力传感器70检测到压力突然降低时，则可判断储料罐10内的目标溶剂已经打空。此时，可以按照系统设定的时间对储料罐10和连接管道30进行氮气吹扫，进一步地减少储料罐10及连接管道30内目标溶剂的残留。
由此，通过上述结构，可以快速检测连接管道30内的压力，从而判断储料罐10内目标溶剂的剩余量，以便于及时进行操作。
基于与上述备料装置100相同的构思，本申请还提供了一种电池生产设备，包括如上所述的备料装置100。其中，备料装置100可以用于电池生产过程中电解液的备料过程中，可以对电解液备料过程中的各种溶剂进行储存及转移。

在此过程中，目标溶剂在连接管道30中可以通过过滤器50进行过滤，然后再进入计量罐21中。当称重传感器22检测到计量罐21内的目标溶剂的重量达到目标要求时，关闭第一进气管41上的第一控制阀43，并且开启第一出气管42上的第一控制阀43，对备料装置100内部进行卸压处理，待卸压完毕之后，再依次关闭第二进气管23上的第二控制阀25及第二出气管24上的第二控制阀25。
此外，在上料过程中，第二压力传感器70还可以对连接管道30内的压力进行检测，当连接管道30内的压力突然降低时，则可判断储料罐10内的目标溶剂已经打空，此时按照系统设定的时间对储料罐10和连接管道30进行氮气吹扫，可以进一步地减少储料罐10和连接管道30内目标溶剂的残留。
氮气吹扫完毕后，依次关闭第一进气管41上的第一控制阀43、第一出气管42上的第一控制阀43、第二进气管23上的第二控制阀25、第二出气管24上的第二控制阀25，则备料过程完成。
