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。
电极组件是电池单体中具体发生电化学反应的部件，而电极组件的制作过程中，需要将正负极浆料涂覆至极片上，而正负极浆料的原材料通过吨袋进行储存，因此需要将原材料吨袋运送至投料装置中进行解包投料。
正负极浆料原材料中的粉料种类有很多，其中还包括一些易燃易爆的危险粉料，因此，解包投料过程中的安全性十分重要。
然而，目前的解包投料过程中容易发生粉料泄漏的问题，导致易燃易爆的危险粉料发生泄漏后暴露于空气中，与空气中的水反应生产硫化氢，或者易燃易爆的危险粉料发生泄漏后容易增加爆炸风险。
基于以上考虑，为了解决目前的解包投料过程中容易发生粉料泄漏的问题，本申请的一个或多个实施例提供了一种投料装置，通过设置第一负压组件，使手套箱内保持负压状态，当在手套箱内操作解包投料时，可以有效降低粉料外溢的问题，从而使得操作过程更加安全。
参阅图1，本申请一实施例提供了一种投料装置100，包括手套箱10及第一负压组件20，手套箱10用于容纳待投放的物料。第一负压组件20与手套箱10连接，用于向手套箱10内通入气体并控制手套箱10内部保持负压状态。
需要说明的是，本申请的投料装置100可以应用于电池生产过程中一些危险粉料的解包投料过程，当然，也可以应用于其他普通粉料的解包投料过程。
手套箱10是指内部能够容纳待投放的物料，并且能够通过手套对箱内的物料进行操作的结构。手套箱10的内部中空设置，并且在箱体上开设连接口，将手套密封连接于连接口。如此，操作人员将手伸进手套内，即可通过手套对箱体内的物料进行操作。其中，待投放的物料可以是电池生产过程中具有一定危险性的原材料。
第一负压组件20是指，能够在手套箱10内部形成负压状态并使手套箱10内部保持负压状态的结构。其中，第一负压组件20能够向手套箱10内通入气体，通过控制通入的气体来调节手套箱10内的压力，从而将手套箱10内部控制在一定的负压状态。
具体地，第一负压组件20向手套箱10内通入的气体为低湿压缩空气，且低湿压缩空气的露点为-60℃。此外，第一负压组件20将手套箱10内的负压值控制在0.2Kpa左右，使得手套箱10内部形成一个微负压状态。
由此，当物料在手套箱10内解包投料时，由于手套箱10内呈负压状态，能够有效降低粉料外溢的问题，降低粉料发生泄漏的概率，提高操作过程的安全性。
在一些实施例中，第一负压组件20包括充气件(图中未示出)及控制件，手套箱10上开设有通气口，充气件与通气口连通。控制件分别与手套箱10及充气件连接，用于调节充气件的充气量以控制手套箱10内部保持负压状态。
具体地，充气件可以但不限于设置为进气管道。在手套箱10的顶部开设通气口， 并将进气管道与通气口连通，利用进气管道向手套箱10内部通入低湿压缩空气。
进一步地，控制件能够获取手套箱10内部的实时压力，并根据实时压力调节进气管道的进气量。例如，当手套箱10内部的实时压力低于预设压力值时，则控制进气管道向手套箱10内通气。当手套箱10内部的实施压力高于预设压力值时，则控制进气管道停止通气。
由此，通过充气件与控制件之间的相互配合，使得手套箱10的内部环境能够稳定的保持在负压状态。
在一些实施例中，控制件包括控制阀(图中未示出)及压力传感器21，控制阀设置于充气件上，并用于控制充气件的启闭，压力传感器21用于检测手套箱10内的压力以控制控制阀开关。
具体地，控制阀设置于进气管道上，并用于控制进气管道的通断。当控制阀打开时，进气管道处于连通状态，此时能够通过进气管道向手套箱10内部通入低湿压缩空气。当控制阀关闭时，进气管道处于断开状态，此时停止向手套箱10内通入低湿压缩空气。
进一步地，压力传感器21设置于手套箱10上，并能够检测手套箱10内的实际压力。这样一来，压力传感器21能够实时检测手套箱10内的压力，并将压力信息传递至控制器，控制器可以根据压力信息来调节控制阀的开启或关闭，从而实现调节充气量的目的。
通过上述结构，可以及时检测手套箱10内的实际压力，并根据实际压力灵活调节控制阀的开关，从而控制手套箱10内的充气量，使得手套箱10内部能够更稳定地保持在负压状态。
在一些实施例中，第一负压组件20还包括与手套箱10连接的第一除尘器22，第一除尘器22用于对手套箱10内部进行除尘。
具体地，第一除尘器22可以但不限于设置为二级除尘器，将第一除尘器22与手套箱10相互连接，在解包投料的过程中，第一除尘器22能够对手套箱10内部进行除尘处理，降低解包过程中粉料或者气体发生外溢的概率。
在一些实施例中，投料装置100还包括设置于充气件与通气口之间的第一过滤器30，第一过滤器30用于过滤由通气口进入充气件的粉尘。
具体地，第一过滤器30设置于手套箱10的顶部，并且与通气口对应设置。在解包过程中，由于需要通过通气口向手套箱10内通入气体，即，通气口通过进气管道与外部连通。此时，解包过程中的粉料可能会从通气口进入进气管道内。
因此，通过设置第一过滤器30，能够对手套箱10内的粉料进行过滤，防止粉料通 过通气口进入充气件内，从而防止粉料溢出至外部环境。
在一些实施例中，手套箱10上开设有第一出料口(图中未示出)，投料装置100还包括相互连接的缓存罐40及第二负压组件50，缓存罐40与第一出料口连通，且沿重力方向设置于手套箱10的下方，第二负压组件50用于向缓存罐40内通入惰性气体并控制缓存罐40内部保持负压状态。
具体地，第一出料口开设于手套箱10的底部。为了使落料过程更加顺利，还可以将手套箱10设置为上宽下窄的结构，使得物料能够经过手套箱10底部的斜面进入第一出料口，并从第一出料口实现出料。
缓存罐40是指能够实现物料的暂存及对物料进行称重复核的结构。缓存罐40沿重力方向设置于手套箱10的下方，并且与第一出料口连通。这样一来，物料能够在重力作用下从第一出料口顺利进入缓存罐40内。
进一步地，第二负压组件50与缓存罐40连接，并且能够向缓存罐40内通入惰性气体，以使缓存罐40内保持负压状态。
其中，第二负压组件50的结构可以与第一负压组件20的结构相同，即，第二负压组件50也可以包括进气管道、控制阀以及压力传感器21，并且控制阀设置于进气管道上，用于控制进气管道的通断。压力传感器21设置于缓存罐40上，并能够检测缓存罐40内的实际压力。这样一来，压力传感器21能够实时检测缓存罐40内的压力，并将压力信息传递至控制器，控制器可以根据压力信息来调节控制阀的开启或关闭，从而实现调节充气量的目的。
此外，第二负压组件50向缓存罐40内通入的惰性气体可以是氮气。具体地，在落料之前，首先通过第二负压组件50向缓存罐40内通入氮气，氮气能够对缓存罐40内原有气体进行置换，防止落料之后，进入缓存罐40的粉料与缓存罐40内原有的气体发生反应从而引发一些安全隐患。
需要说明的是，在缓存罐40的下游通常还会设置如搅拌组件等其他结构，当设置搅拌组件时，粉料在搅拌组件内进行混合搅拌，会伴随产生一些危险气体，这些气体可能会进入缓存罐40内，并停留在缓存罐40内。
而在落料过程中，当手套箱10内的粉料落入至缓存罐40内时，粉料会与缓存罐40内原有的危险气体发生反应，存在一定的安全隐患。
因此，在落料开始之前，通过第二负压组件50向缓存罐40内通入氮气进行置换，能够排除缓存罐40内的原有气体，提高落料过程的安全性。
通过上述结构，能够对解包之后的粉料进行暂存，并且在缓存罐40内形成负压状态，降低落料过程中粉料发生外溢的概率。此外，还能够利用第二负压组件50向缓存罐40内通入惰性气体以使物料进入缓存罐40之后更加安全。
在一些实施例中，投料装置100还包括振动件60，振动件60设置于手套箱10的外壁上。
具体地，振动件60可以设置为震锤，并且设置于手套箱10的外壁上。当手套箱10内的粉料经过第一出料口落料至缓存罐40的过程中，开启震锤进行辅助落料，使得落料更加彻底，提高落料精度。
在一些实施例中，投料装置100还包括设置于第二负压组件50上的第二过滤器70，第二过滤器70用于过滤进入第二负压组件50的粉尘。
具体地，第二过滤器70的结构可以设置为与第一过滤器30的结构相同，并且也是用于对落料过程中的粉料进行过滤，防止粉料经由第二负压组件50的进气管道进入外部环境中。
因此，通过设置第二过滤器70，能够对缓存罐40内的粉料进行过滤，防止粉料溢出至外部环境。
在一些实施例中，投料装置100还包括设置于缓存罐40上的称重传感器80，称重传感器80用于测量缓存罐40及其内部物料的总重量。
具体地，称重传感器80可以对缓存罐40及其内部物料的总重量进行测量。在落料之前，缓存罐40内部中空，此时称重传感器80对其进行称重，则得到缓存罐40的自身重量。
随着落料的进行，粉料从手套箱10内落入至缓存罐40中。与此同时，称重传感器80所测量的变化值即为缓存罐40中进入粉料的总量。当称重传感器80所检测到的粉料的重量达到目标重量时，即可关闭缓存罐40与手套箱10之间的落料阀门，停止落料。
通过上述结构，能够在落料的过程中准确测量进入缓存罐40内的物料的重量，从而更好地控制后续物料的混合比例，提高投料精度。
在一些实施例中，缓存罐40上开设有第二出料口，投料装置100还包括相互连接的搅拌组件91及第三负压组件92，搅拌组件91的进料管道与第二出料口连通，第三负压组件92用于向搅拌组件91内通入气体并控制搅拌组件91内部保持负压状态。
具体地，缓存罐40的底部开设第二出料口，并且将搅拌组件91与第二出料口连通，以使缓存罐40内的粉料能够通过第二出料口进入搅拌组件91内部。
其中，搅拌组件91可以包括搅拌罐，搅拌罐通过第二出料口与缓存罐40连通，以使缓存罐40内经过称重的粉料能够顺利进入搅拌罐内进行搅拌混合。
第三负压组件92与搅拌罐连接，并且能够向搅拌罐内通入惰性气体，以使搅拌罐内保持负压状态。
其中，第三负压组件92的结构可以与第一负压组件20及第二负压组件50的结构相同，即，第三负压组件92也可以包括进气管道、控制阀以及压力传感器21，并且控制阀设置于进气管道上，用于控制进气管道的通断。压力传感器21设置于搅拌罐上，并能够检测搅拌罐内的实际压力。这样一来，压力传感器21能够实时检测搅拌罐内的压力，并将压力信息传递至控制器，控制器可以根据压力信息来调节控制阀的开启或关闭，从而实现调节充气量的目的。
通过设置搅拌组件91，使得缓存罐40内经过称重的粉料能够顺利进入搅拌组件91并且进行搅拌混合。与此同时，第三负压组件92能够使得搅拌组件91内部保持负压状态，避免搅拌过程中出现粉料溢出的情况，从而提高搅拌过程的安全性。
在一些实施例中，投料装置100还包括清管件93，清管件93可移动地设置于搅拌组件91的进料管道内，并用于清除进料管道内的残留物料。
具体地，当粉料在搅拌组件91内部进行搅拌混合并发生反应时，一部分粉料可能会进入搅拌组件91的进料管道内，并停留在进料管道内形成堵塞。因此，在搅拌组件91进料之前，首先通过清管件93对进料管道内残留的物料进行清除，使得缓存罐40内的物料能够更顺利地进入搅拌组件91。
其中，清管件93可以但不限于设置为清管气缸，清管气缸可移动地设置于进料管道内，通过清管气缸在进料管道内的移动，能够带走进料管道内残留的物料，从而实现物料的清除。
通过上述结构，可以清除搅拌组件91的进料管道中残留的物料，使得缓存罐40内的物料能够更顺利地进入搅拌组件91中，并进行搅拌混合操作。
基于与上述投料装置100相同的构思，本申请还提供了一种电池生产设备，包括如上所述的投料装置100。其中，投料装置100可以对正负极浆料的原材料进行解包投料，并对各种物料进行搅拌混合，以形成正负极浆料，然后将正负极浆料涂覆于极片上，从而形成电极组件。
根据一个或多个实施例，本申请在使用时，首先打开手套箱10的箱门，将物料包装放入手套箱10内并关闭箱门。向手套箱10内通入低湿压缩空气，并控制手套箱10内 的负压值保持在0.2Kpa左右。与此同时，通过手套箱10对物料包装进行解包投料操作，以使粉料落入手套箱10内进行暂存。
投料完毕之后，首先向缓存罐40内通入氮气，对缓存罐40内原有气体进行置换，并且控制缓存罐40内的负压值保持在0.2Kpa左右。然后打开手套箱10与缓存罐40之间的落料阀，使手套箱10内的粉料能够落入至缓存罐40内。与此同时，开启震锤进行辅助落料，使粉料能够更彻底地进入缓存罐40内。
缓存罐40上的称重传感器80进行实时称重，当进入缓存罐40的粉料的重量达到目标重量时，关闭落料阀，完成落料。
落料结束之后，控制清管件93对搅拌组件91的进料管道进行清管操作，然后打开缓存罐40与搅拌组件91之间的阀门，以使缓存罐40内的粉料能够顺利进入搅拌组件91。与此同时，向搅拌组件91内部持续通入氮气，并控制搅拌组件91内部的负压值保持在0.2Kpa左右，以形成微负压环境。
当缓存罐40上的称重传感器80的数据不再减少时，则说明缓存罐40内的粉料已经完全排出，此时关闭所有阀门，完成整个的投料及落料过程。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
