本申请要求2021年09月02日申请的，申请号为202122113571.4，名称为“注液装置”的中国专利申请的优先权，在此将其全文引入作为参考。
技术领域
本申请涉及电池注液设备技术领域，特别是涉及一种注液装置。
背景技术
对电池注液之前，需要对电池外壳的内部抽真空。传统的注液设备是通过设置一注液块，注液块上开设注液通道、抽气通道以及同时与注液通道及抽气通道连通的输出口，输出口用于与电池外壳的内部连通。
注液块需要重复使用，而由于注液块仅具备一个输出口，注液通道和抽气通道的输出端彼此连通，在抽气之后，抽气通道和电池外壳的内部均为负压，注液通道输入的电解液容易进入抽气通道内，影响抽气装置的使用。
申请内容
基于此，有必要针对电解液容易进入注液块的抽气通道的问题，提供一种避免电解液影响抽气装置的注液装置。
为解决上述技术问题，本申请采用的一个技术方案是：一种注液装置，包括：
托板，用于承载电池；

具体实施方式
本申请提供一种注液装置，为使本申请的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本申请进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
如图2-图4所示，本申请一实施例提供的注液装置100，用于通过电池200的注液口201对电池200内部抽真空并且往电池200内部注入电解液。该注液装置包括托板11、第一注液杯12、抽气组件20、注液组件30及第二注液杯40。
托板11用于承载电池200，第一注液杯12连接于托板11，且第一注液杯12具有与电池200的注液口201连通的连通口121以及与连通口121连通的进液口122和抽气口123，第二注液杯40设置于第一注液杯12的上方，用于储存电解液。
抽气组件20具有一端用于与抽气装置连通的抽气通道21，注液组件30连接于抽气组件20，且设置于第一注液杯12与第二注液杯40之间，以与抽气组件20同步靠近和远离第一注液杯12，注液组件30具有一注液通道31。
抽气组件20和注液组件30同步靠近并抵持于第一注液杯12时，抽气通道21远离抽气装置的另一端与抽气口123连通，注液通道31的一端与进液口122连通。
注液组件30和第二注液杯40可相互靠近和远离，注液组件30靠近并抵持于第一注液杯12时，注液通道31的一端与进液口122连通，第二注液杯40靠近并抵持于注液组件30时，第二注液杯40与注液通道31远离进液口122的另一端连通。
通过设置上述的注液装置，将电池200放置于托板11上，然后将抽气组件20及注液组件30靠近并抵持于第一注液杯12上，接下来将第二注液杯40抵持于注液组件30上，使得抽气装置通过抽气通道21、抽气口123及连通口121与电池200的注液口201连通，第二注液杯40则通过注液通道31、进液口122及连通口121与电池200的注液口201连通。初始时，第二注液杯40的出液口处于关闭状态，抽气装置动作，对电池200内部、抽气通道21及注液通道31抽真空，抽真空之后关闭抽气装置，然后打开第二注液杯40的出液口，使得第二注液杯40内的电解液通过注液通道31流入电池200内部。由于抽气装置与第二注液杯40分别通过抽气组件20及注液组件30与托板11上的电池200连通，而且抽气组件20及注液组件30与第一注液杯12、第二注液杯40及抽气装置分体设置，故可以有效地避免电解液进入抽气装置，影响抽气装置的使用。
需要进行说明的是，注液组件30、第二注液杯40及第一注液杯12中任意两个在竖直方向上均可相互靠近和远离，即注液组件30与第二注液杯40可相互靠近和远离、注液组件30和第一注液杯12可相互靠近和远离，以及第一注液杯12与第二注液杯40可相互靠近和远离。而注液组件30位于第一注液杯12与第二注液杯40之间，故第一注液杯12和第二注液杯40均与注液组件30相抵持。
可以理解的是，注液组件30、第二注液杯40及第一注液杯12三者可以均沿竖直方向升降，或者当注液组件30、第二注液杯40及第一注液杯12中的一个固定时，另外两个均沿竖直方向可升降。
请参阅图2、图3及图5，在一些实施例中，托板11上开设有托槽，托槽用于承载电池200，并对电池200进行定位，避免注液的时候电池200发生晃动。
在一些实施例中，第一注液杯12还具有中转腔124，连通口121、进液口122及抽气口123均与中转腔124连通，连通口121开设于中转腔124的底壁。如此，在进行抽真空和注液时，气体及电解液均会经过中转腔124，经过中转腔124的缓冲，可以避免电解液进入抽气口123。
另外，需要说明的是，第一注液杯12与抽气组件20、注液组件30及第二注液杯40均分体设置，故在托板11上的电池200完成注液之后，中转腔124内可能存在部分电解液未流入电池200内部，此时可以将托板11和第一注液杯12搬离注液组件30的下方，并且静置一段时间，使得电解液完全进入电池200的内部，同时也可以使得电池200内外压力在静置之后相等。
进一步地，进液口122与抽气口123均开设于中转腔124的顶壁，以与位于第一注液杯12上方的注液组件30及抽气组件20连通。
实际应用中，中转腔124的底壁呈漏斗状，且连通口121位于中转腔124的底壁的最低位置，以避免电解液囤积在中转腔124的底壁。
具体地，中转腔124的侧壁与底壁之间通过弧形面衔接，以避免电解液囤积。
在一些实施例中，注液装置还包括阻挡块13，阻挡块13连接于第一注液杯12，且位于中转腔124内，阻挡块13与中转腔124的顶壁或侧壁围合形成一导流通道，导流通道与抽气口123连通，且导流通道的开口朝向中转腔124的侧壁或顶壁，以避免从滴落在中转腔124底壁的电解液飞溅进入抽气口123。
可以理解的是，阻挡块13的作用是阻挡抽气口123直面中转腔124的底壁，从而避免滴落在底壁上的电解液飞溅进入抽气口123。
另外，需要说明的是，当阻挡块13连接于中转腔124的侧壁时，导流通道的开口朝上，飞溅的电解液可从导流通道的开口进入导流通道，为了避免飞 溅的电解液堆积在导流通道内，导流通道的底部开设有排液孔，排液孔用于排出堆积的电解液。
进一步地，阻挡块13连接于中转腔124的顶壁，且连接于抽气口123与进液口122之间，阻挡块13具有一倾斜面，倾斜面与顶壁围合形成导流通道，抽气口123与进液口122均与导流通道连通。
实际应用中，阻挡块13开设有沿竖直方向贯穿自身的贯通孔131，贯通孔131与进液口122对应，方便电解液注入，避免电解液撞击在阻挡块13的斜面上从而在中转腔124内飞溅。
在一些实施例中，注液装置还包括第一配合件141及第二配合件142，第一配合件141连接于托板11，第二配合件142连接于第一注液杯12，且第一配合件141和第二配合件142可拆卸地连接，从而实现将第一注液杯12和托板11锁紧固定。
实际应用中，第一配合件141为转动连接于托板11的卡爪，第二配合件142位于固定连接于第一注液杯12的卡块，将第一注液杯12连接于托板11之后，转动卡爪，使得卡爪与卡块卡接，从而将第一注液杯12和托板11锁紧固定。
可以理解的是，第一配合件141与第二配合件142也可以是其他的配合方式，例如电磁铁与金属块配合、卡块与凹槽配合以及夹爪与凸块配合等，在此不做限制，只要能实现将第一注液杯12和托板11锁紧固定即可。
在一些实施例中，注液装置还包括定位件15，定位件15设置于托板11，第一注液杯12开设有定位孔，第一注液杯12装设于托板11上时，定位件15穿设于定位孔，以确保第一注液杯12准确地安装托板11上，从而保证第一注液杯12安装在托板11上时第一注液杯12的连通口121与电池200的注液口201连通。
实际应用中，定位件15为定位销。当然，在其他实施例中，定位销也可以设置于第一注液杯12，对应托板11上开设有定位孔。
在一些实施例中，注液装置还包括支撑组件，支撑组件设置于托板11，用于在第一注液杯12安装于托板11上时支撑第一注液杯12。
进一步地，支撑组件包括第一支撑件161及第二支撑件162，第一支撑件161一端连接于托板11，第二支撑件162固定连接于第一支撑件161远离托板11的另一端，第一支撑件161提供推动第一支撑件161远离托板11的弹力，而第二支撑件162用于在第一注液杯12安装于托板11上时与第一注液杯12相抵持。
如此，需要连接第一注液杯12和托板11时，第一注液杯12上的定位孔穿过托板11上的定位件15，然后克服第一支撑件161的弹力下压第一注液杯12，直至下压至能够将第一配合件141与第二配合件142连接在一起的位置，将第一配合件141和第二配合件142连接在一起从而将第一注液杯12与托板11锁紧；需要分离第一注液杯12和托板11时，先将第一配合件141和第二配合件142分离，第一注液杯12在第一支撑件161和第二支撑件162的作用下会弹起，然后拆离第一注液杯12即可。
实际应用中，第一支撑件161为弹簧，第二支撑件162为活动块，弹簧与活动块均套设于定位销的外侧，定位销沿竖直方向延伸，也可以对弹簧及活动块的移动进行导向。
请参阅图3及图4，在一些实施例中，抽气组件20包括彼此连接的抽气嘴22及抽气接头23，抽气嘴22内部的通道与抽气接头23内部的通道相互连通以形成抽气通道21，抽气接头23用于与抽气装置连通，抽气组件20靠近并抵持于第一注液杯12时，抽气嘴22与抽气口123连通。
进一步地，抽气组件20还包括抽气块24，抽气块24具有第一连通通道，抽气嘴22与抽气接头23分别连接于抽气块24的相对两端，且抽气嘴22内部的通道以及抽气接头23内部的通道分别与抽气块24的第一连通通道的相对两端连通，以使得抽气嘴22内部的通道、第一连通通道及抽气接头23内部的通道共同连通形成抽气通道21。
在一些实施例中，注液组件30包括彼此连接的注液嘴32及注液接头33，注液嘴32内部的通道与注液接头33内部的通道相互连通以形成注液通道31，注液组件30靠近并抵持于第一注液杯12时，注液嘴32与进液口122连通，第二注液杯40靠近并抵持于注液组件30时，第二注液杯40与注液接头33连通。
进一步地，注液组件30还包括注液块34，注液块34具有第二连通通道，注液嘴32与注液接头33分别连接于注液块34的相对两端，且注液嘴32内部的通道以及注液接头33内部的通道分别与注液块34的第二连通通道的相对两端连通，以使得注液嘴32内部的通道、第二连通通道及注液接头33内部的通道共同连通形成注液通道31。
需要说明的是，抽气嘴22与注液嘴32均与第一注液杯12相抵持，且抽气嘴22与注液嘴32抵持于第一注液杯12抵持时，抽气嘴22和注液嘴32与第一注液杯12之间保持密封，以避免气体和电解液泄漏。
在一些实施例中，注液嘴32具有彼此连接的抵持部及尖端，注液嘴32内部的通道贯穿抵持部与尖端，抵持部用于与第一注液杯12相抵持，以确保密封性，尖端用于穿过进液口122并伸入中转腔124内，以直接将电解液输入中转腔124内。
请参阅图2，在一些实施例中，注液装置还包括驱动组件50，驱动组件50与抽气组件20及注液组件30传动连接，以驱动抽气组件20及注液组件30靠近和远离托板11和第一注液杯12。
需要说明的是，托板11固定在注液组件30的下方时，第二注液杯40也沿竖直方向可升降，且第二注液杯40可以通过该驱动组件50驱动升降，也可以额外设置驱动机构驱动第二注液杯40升降，在此不作限制。
需要进一步说明的是，托板11固定在注液组件30的下方，是指托板11上的电池200需要抽真空及注液时固定在注液组件30的下方，注液完成之后，托板11和第一注液杯12可搬离注液组件30的下方。即注液装置具有一机架，注液组件30及第二注液杯40均沿竖直方向可升降地设置于机架上，机架具有一位于注液组件30下方的安装位，而托板11可拆卸地装设于安装位。
在另一些实施例中，驱动组件50与托板11传动连接，以驱动托板11和第一注液杯12升降，从而靠近和远离抽气组件20及注液组件30，故本实施例中抽气组件20设置于托板11的上方。
需要说明的是，两组实施例中驱动组件50的结构可以相同，下文主要以驱动组件50与抽气组件20及注液组件30传动连接，且抽气组件20位于托板11上方为例进行说明。
