本申请涉及一种电池化成用负压组件的清洗工装，清洗工装包括储液箱1101和储存杯2000，储液箱1101设置在清洗工装的机箱中，储液箱1101用于储存清洗液，储液箱1101中的清洗液能够输送至储存杯2000，储存杯2000用于与负压杯1000对接。具体地，负压组件包括负压杯1000和吸嘴1001，负压组件与储存杯2000连通，借助厂房的负压动力源1002为负压组件提供负压，储存杯2000中的清洗液负压吸入负压杯1000，以完成对负压组件的清洗。
可以理解的是，无需将负压组件逐个拆下，而是将化成设备的负压组件移动至清洗工装处，负压组件与储存杯2000对接，并利用负压组件原有的负压动力源1002为吸入清洗液提供负压。一方面，免除拆卸负压组件的操作，降 低工作强度，替代人工清洗，提高效率，还能够避免破坏负压组件的装配精度，避免影响负压组件的气密性；另一方面，合理利用厂房的现有设备，节约清洗成本。
负压杯1000吸入清洗液的过程中，为避免清洗液进入负压动力源1002的气路中，进一步地设计储存杯2000的容积不大于负压杯1000的容积。当然，作为替换方案，也可通过控制清洗液的流量来确保储存杯2000中清洗液的量不足以进入负压动力源1002的气路，一些示例中，利用节流阀控制清洗液注入储存杯2000的流量。
结合附图，清洗工装包括动力部件1102，动力部件1102设置在清洗工装的机箱中，储存杯2000与动力部件1102连接，动力部件1102与储液箱1101连接，动力部件1102为清洗液的流动提供动力。进一步地，设计动力部件1102具有正向驱动和反向驱动两种工作方式，动力部件1102正向驱动时，能够使清洗液流向储存杯2000，动力部件1102反向驱动时，能够使清洗液从储存杯2000流出。一些示例中，动力部件1102设置为蠕动泵。
清洗工装具有第一管路，第一管路分别连通储液箱1101和储存杯2000，动力部件1102为第一管路中的清洗液流动提供动力。具体地，在动力部件1102的作用下，储液箱1101中的清洗液经第一管路流向储存杯2000，实现储液箱1101向储存杯2000注液。
进一步地，为限定清洗液在第一管路中的流动方向为从储液箱1101流向储存杯2000，第一管路设置有第一单向阀1201，具体地，第一单向阀1201与储液箱1101的出液口连接。可以理解的是，设置第一单向阀1201还能够实现防爆。一些示例中，第一单向阀1201设置为机械阀。
结合附图，清洗工装包括导液部件2100，导液部件2100具有第一端和第二端，导液部件2100设置有导液通道，可以理解的是，导液通道从导液部件2100的第二端贯穿至第一端。导液部件2100与储存杯2000连接，储存杯2000的内腔通过导液通道与负压组件连通，具体地，导液部件2100的第二端连通储存杯2000的内腔，导液部件2100的第一端用于连通负压组件，在负压动力源1002的作用下，储存杯2000中的清洗液经导液部件2100的导液通道进入负压组件的吸嘴1001和负压杯1000，清洗液在流向负压杯1000的过程中， 对吸嘴1001也能够起到清洗作用。
可以理解的是，在负压组件与导液部件2100第一端紧密连接或者紧密压合的情况下，利用具有导液通道的导液部件2100能够增强对清洗液的负压吸引，以实现利用较小的负压值即可进行负压吸引和清洗，降低负压动力源1002的输出功率。
一些示例中，导液部件2100的第二端从储存杯2000的杯口伸入储存杯2000，导液部件2100的第一端用于对接负压组件。进一步地，导液部件2100的第一端设置有密封圈或密封垫，提高密封性，防止清洗液泄漏。
关于负压组件的对接方式，作为替换方案，也可设计为：负压组件与储存杯2000的杯口紧密对接或者紧密压合，这种情况下，储存杯2000的杯口设置有密封圈或密封垫。
关于导液部件2100的第二端的位置，作为替换方案：一些示例中，导液部件2100的第二端与储存杯2000的侧壁连接，具体地，导液部件2100的第二端在储存杯2000的侧壁连通至储存杯2000的内腔。进一步地，导液部件2100的第二端设置在储存杯2000的侧壁靠近底部的位置。一些示例中，导液部件2100的第二端设置在储存杯2000的底壁。
在储存杯2000中的清洗液进入负压杯1000的过程中，当储存杯2000中清洗液液面降低至导液部件2100的第二端高度或者低于导液部件2100的第二端高度时，储存杯2000中的空气经导液部件2100负压吸引至负压组件的清洗液中。具体地，在负压杯1000中，空气混合清洗液，能够产生气泡，使得清洗液处于翻滚、冒泡、“沸腾”的状态，促进清洗。
应说明的是，若导液部件2100的第二端设置在储存杯2000中，导液部件2100的第二端与储存杯2000中的液面之间存在空隙时，则说明储存杯2000中清洗液液面已降低至导液部件2100的第二端高度或者低于导液部件2100的第二端高度。若导液部件2100的第二端设置为与储存杯2000的侧壁连接或者导液部件2100的第二端与储存杯2000的底壁连接，导液部件2100的第二端在储存杯2000中的液面处部分或全部露出，则说明储存杯2000中清洗液液面已降低至导液部件2100的第二端高度或者低于导液部件2100的第二端高度。
作为一种实施方式，储存杯2000与气源连通，以使气源的气体负压吸入储存杯2000，一方面为清洗工装内平衡气压，另一方面为负压组件中清洗液的翻滚、冒泡补充气流。一些示例中，以外界的空气作为气源；一些示例中，以气瓶作为气源，气瓶中储存有不溶于水的惰性气体或氮气，这种情况下，清洗过程中，气瓶的气压应大于负压动力源1002的负压。
具体地，储存杯2000的侧壁设置有连通外界的进气口。结合附图，清洗工装设置有第二单向阀1202，第二单向阀1202与储存杯2000的进气口连通，气体经第二单向阀1202进入清洗工装。
一些示例中，储存杯2000通过第二单向阀1202连通外界，外界空气能够经第二单向阀1202进入储存杯2000。具体地，第二单向阀1202设置在储存杯2000的进气口处。一些示例中，储存杯2000通过第二单向阀1202连通气瓶，一方面，第二单向阀1202能够限定气流方向，另一方面，第二单向阀1202具有防爆作用。
清洗液在清洗负压组件的过程中，负压动力源1002在储存杯2000中所产生的内外气压差能够触发第二单向阀1202，空气通过第二单向阀1202不断进入储存杯2000，为负压杯1000补充气流，使得负压杯1000中的清洗液持续处于翻滚、冒泡、“沸腾”的状态。
可以理解的是，启动动力部件1102的正向驱动开始注液后，储液箱1101内与外界大气的气压差能够也触发第二单向阀1202，空气经第二单向阀1202进入清洗工装内的管路中，空气从管路进入储液箱1101，能够确保内外气压平衡，确保清洗工装中清洗液的流动。
进一步地，导液部件2100的第一端设置有凹陷容腔2103，导液通道与凹陷容腔2103连通，凹陷容腔2103用于对接负压组件的吸嘴1001。具体地，在负压组件与储存杯2000对接的情况下，吸嘴1001的内腔与凹陷容腔2103对接。可以理解的是，吸嘴1001的一端凸出用于对接凹陷容腔2103、另一端与负压杯1000连接，吸嘴1001一端凸出的结构与凹陷容腔2103之间为非接触的状态。
在清洗液负压吸入负压杯1000的过程中，吸嘴1001能够浸在凹陷容腔2103的清洗液中，以便充分清洗吸嘴1001。可以理解的是，在负压吸引空气 进入负压杯1000的过程中，所吸引的空气也能够与凹陷容腔2103中的清洗液混合，使得凹陷容腔2103中的清洗液翻滚、冒泡、“沸腾”，促进对吸嘴1001的清洗。
一些示例中，凹陷容腔2103设置为锥形容腔，锥形容腔的小径端与导液通道连通，锥形容腔的大径端用于连通负压组件。具体地，凹陷容腔2103设置为喇叭口。
作为一种实施方式，导液部件2100包括端部结构2102和吸管2101，结合附图，端部结构2102位于储存杯2000的杯口，端部结构2102用于与负压组件对接，凹陷容腔2103设置在端部结构2102，吸管2101与端部结构2102连接，吸管2101伸入储存杯2000中。
结合附图，储存杯2000设置有溢流口，溢流口设置在储存杯2000的侧壁，溢流口贯穿储存杯2000的侧壁，溢流口与储液箱1101连通。具体地，清洗工装包括溢流管2202，溢流管2202与溢流口连接，溢流管2202与储液箱1101连接，溢流管2202与储液箱1101的进液口连通。可以理解的是，在向储存杯2000注液的过程和清洗液清洗负压组件的过程中，一些清洗液会从溢流口溢出，经溢流管2202回流至储液箱1101。
可以理解的是，在设置有溢流管2202的情况下，一些示例中，可设计第二单向阀1202与储液箱1101连接或者第二单向阀1202与溢流管2202连接。这种情况下，储存杯2000的溢流口与进气口合二为一，溢流口与气源连通，气体通过溢流口进入储存杯2000。具体地，外界空气经第二单向阀1202进入储液箱1101后，可从溢流管2202进入储存杯2000。一些示例中，第二单向阀1202设置在储液箱1101的顶部。
进一步地，在负压组件端口与导液部件2100连通的情况下，导液部件2100的第二端与负压组件端口的距离大于溢流口与负压组件端口的距离。
负压组件清洗完成后，破真空，负压杯1000中的清洗液回流至储存杯2000，储存杯2000将清洗液排出。具体地，清洗工装具有第二管路，第二管路分别连通储存杯2000和储液箱1101，动力部件1102为第二管路中的清洗液流动提供动力。具体地，在动力部件1102的作用下，储存杯2000中的清洗液经第二管路流向储液箱1101，实现储存杯2000向储液箱1101排液。
进一步地，为限定清洗液在第二管路中的流动方向为从储存杯2000流向储液箱1101，第二管路设置有第三单向阀1203，具体地，第三单向阀1203与储液箱1101的进液口连接。可以理解的是，设置第三单向阀1203还能够实现防爆。一些示例中，第三单向阀1203设置为机械阀。
清洗工装设置有第四单向阀1204，清洗工装中的空气能够经第四单向阀1204排出。一些示例中，第四单向阀1204与储液箱1101连接。具体地，第四单向阀1204设置在储液箱1101的顶部，清洗液经第二管路进入储液箱1101的过程中，储液箱1101中的空气从第四单向阀1204排出。
可以理解的是，启动动力部件1102的反向驱动开始排液后，储液箱1101内与外界大气的气压差触发第四单向阀1204，清洗工装内管路中的空气排出，储液箱1101中的空气经第四单向阀1204排出，能够确保内外气压平衡，确保清洗液的流动。
一些示例中，设置第四单向阀1204通过管路与废气收集系统连通，以便收集清洗工装所排出的废气，防止易爆、腐蚀性气体排放至大气。
当然，关于第四单向阀1204的位置，还可替换设计为第四单向阀1204与储存杯2000的侧壁连接，可以理解的是，储液箱1101中的空气经溢流管2202流至储存杯2000，再从第四单向阀1204排出。这种情况下，储存杯2000侧壁与第二管路的连通口应小于溢流口，避免清洗液充满溢流管2202以致储液箱1101的气体无法排出。
作为一种实施方式，清洗工装包括第一三通接头1300，第一三通接头1300的第一端与第一单向阀1201连接，第一三通接头1300的第二端与第三单向阀1203连接，第一三通接头1300的第三端与动力部件1102连接。可以理解的是，动力部件1102所在的管路、第一单向阀1201所在的管路和第三单向阀1203所在的管路在第一三通接头1300处交汇。一些示例中，第一三通接头1300设置为三通阀。
具体地，在动力部件1102正向驱动的情况下，第一单向阀1201开启，第三单向阀1203关闭，储液箱1101经第一单向阀1201连通与储存杯2000之间的第一管路；在动力部件1102反向驱动的情况下，第一单向阀1201关闭，第三单向阀1203开启，储存杯2000经第三单向阀1203连通与储液箱1101之间 的第二管路。
关于清洗工装的注液和排液，作为替换方案，还可设计为：清洗工装不具有第二管路，第一管路不具有第一单向阀1201，注液和排液均通过第一管路实现。
结合附图，清洗工装包括过滤部件3000，过滤部件3000包括至少一层过滤网，过滤部件3000与储液箱1101的进液口连接，过滤部件3000用于过滤回流至储液箱1101的清洗液，有利于清洗液的重复使用。
具体地，过滤部件3000设置在第二管路上，可以理解的是，完成清洗后，从储存杯2000中排出的清洗液经过滤部件3000处理后，再回流至储液箱1101中。一些示例中，过滤部件3000设置在第一三通接头1300的第二端与储液箱1101之间的管路上。
关于过滤部件3000的位置，作为替换方案：过滤部件3000也可设置在储液箱1101内，具体地，过滤部件3000位于进液口处。
一些示例中，设计过滤部件3000对溢流管2202中回流的清洗液进行过滤，具体地，设置溢流管2202与过滤部件3000连接。一些示例中，在设置有第二汇流管2203的情况下，第二汇流管2203通过管路与过滤部件3000连接。
作为一种实施方式，考虑到化成设备的具有多个负压组件，相应地，清洗工装所包括的储存杯2000设置为多个，各储存杯2000分别对接一个负压组件，提高清洗效率，保证清洗的均匀性，每个负压组件都能够实现有效的清洗。
结合附图，清洗工装包括第一汇流管2201，第一汇流管2201连接多个储存杯2000，第一汇流管2201与第一管路连通。可以理解的是，在动力部件1102的作用下，储液箱1101中的清洗液经第一管路流入第一汇流管2201，第一汇流管2201中的清洗液注入各储存杯2000。
进一步地，清洗工装包括第二三通接头，第二三通接头的一端与动力部件1102连接，第二三通接头的其余两端分别与第一汇流管2201的两端连接。具体地，在注液过程中，清洗液经第二三通接头从第一汇流管2201的两端流入，避免清洗液在第一汇流管2201中产生首尾效应。一些示例中，第二三通接头设置为三通阀。
可以理解的是，在储存杯2000设置为多个的情况下，一些示例中，设计 清洗工装包括第二汇流管2203，各储存杯2000的溢流管2202分别与第二汇流管2203连接，第二汇流管2203与储液箱1101连接，第二汇流管2203与储液箱1101的进液口连通。
一些示例中，清洗工装包括第一液位计，第一液位计与储液箱1101连接，第一液位计用于检测储液箱1101中清洗液的液位高度，以便进行加液、补液和排液，有效防止储液箱1101中的清洗液溢出。具体地，第一液位计设置为液位传感器，液位传感器与清洗工装的控制模组电连接，以便实时反馈液位高度。
在第二单向阀1202与储液箱1101连接的情况下，通过第一液位计对储液箱1101内的液位高度监控，可避免清洗液堵塞第二单向阀1202，避免清洗工装内部的气路堵塞。可以理解的是，在第四单向阀1204与储液箱1101连接的情况下，第一液位计对储液箱1101内的液位高度监控也能起到相似作用。
一些示例中，清洗工装包括第二液位计，第二液位计连接储存杯2000连接，注液和排液过程中，第二液位计用于检测储存杯2000中清洗液的液位高度。具体地，第一液位计设置为液位传感器，液位传感器与清洗工装的控制模组电连接，以便实时反馈液位高度。
本申请涉及一种电池化成用负压组件的清洗方法，清洗方法采用如前各实施例所述的清洗工装实现对负压组件的清洗，利用厂房中与负压组件连接的现有的负压动力源1002，将储存杯2000中的清洗液吸入负压组件。清洗方法的具体操作如下。
连通负压组件与储存杯2000：将负压组件与储存杯2000所连接的导液部件2100连通，负压组件倒扣在导液部件2100的第一端，负压杯1000与导液部件2100的导液通道连通。
向储存杯2000注入清洗液：动力部件1102正向驱动，清洗工装的第一管路连通，储液箱1101中的清洗液经第一管路进入储存杯2000。待储存杯2000中的清洗液液位高度达到预设位置，则可停止注液；或者设定经过预设时长的注液后，则停止注液。
完成前期准备后，启动与负压组件所连接的负压动力源1002，储存杯2000中的清洗液经导液部件2100进入负压组件，清洗负压组件的吸嘴1001和负压 杯1000。负压动力源1002在运行过程中，可通过比例阀控制负压值，根据负压组件的型号设定负压吸引的时长，即设定清洗时长。
清洗完成后，关闭负压动力源1002，解除负压，受正压和自重作用，负压组件中的清洗液回流至储存杯2000。
动力部件1102反向驱动，清洗工装的第二管路连通，储存杯2000中的清洗液经第二管路回流至储液箱1101。
应说明的是，在清洗液进入负压组件的过程中，当储存杯2000中清洗液液面降低至导液部件2100的第二端高度或者低于导液部件2100的第二端高度时，由于负压动力源1002的负压吸引，储存杯2000中的空气经导液部件2100负压吸引至负压组件，空气混合清洗液，有助于清洗负压组件的负压杯1000和吸嘴1001。
可以理解的是，负压杯1000中吸入的空气与清洗液混合，以使负压杯1000中清洗液形成翻滚、冒泡、“沸腾”的状态，有助于充分清洗负压杯1000。
进一步地，导液部件2100在第一端设置有凹陷容腔2103，负压组件的吸嘴1001浸在凹陷容腔2103的清洗液中，负压动力源1002负压吸引所吸引的空气混合凹陷容腔2103中的清洗液，以使清洗液处于翻滚、冒泡、“沸腾”的状态，有助于充分清洗吸嘴1001。

以上结合附图对本申请的实施方式作了详细说明，但是本申请不限于上述实施方式，在所述技术领域普通技术人员所具备的知识范围内，还可以在不脱离本申请宗旨的前提下作出各种变化。
本申请的描述中，专利名称若出现“、”，表示“和”的关系，而不是“或”的关系。例如专利名称为“一种A、B”，说明本申请所要求保护的内容为：
主题名称为A的技术方案和主题名称为B的技术方案。
