技术领域
本申请涉及流量监测领域，尤其涉及一种检测工装。
背景技术
目前，环境能源问题使社会进步面临严峻形势，低碳环保成为未来经济发展的一大主题。能量的储存和高效利用引起了各方面的重视，锂离子电池单元作为能量储存的最小单元而存在。节能减排是汽车产业可持续发展的关键，电动车辆由于其节能环保的优势成为汽车产业可持续发展的重要组成部分。对于电动车辆而言，电池技术又是关乎其发展的一项重要因素。电池是将多个电池单体有效连接的一种结构形式，通过将一定数量的电池单体进行串联/并联/串并混联来满足为用电设备供电的需求。在电池单体的生产过程中，分析工装需要对电解液进行吸入分析，则如何检测分析工装的吸入口的性能，成为了一个亟待解决的问题。
发明内容
本申请提供了一种检测组件及工装，其能够集约化地检测分析工装吸入口的性能。
本申请是这样实现的：一种检测组件，包括，
接口，接口的一端用于接入待测设备，接口包括第一接口、第二接口，
第一三通阀，第一三通阀包括第一接入阀门、第一通气阀门和第一检测阀门，第一接口的另一端与第一接入阀门连接，第一通气阀门接大气，第一通气阀门可开闭；第二三通阀，第二三通阀包括第二接入阀门、第二通气阀门和第二检测阀门，第二接口的另一端与第二接入阀门连接，第二通气阀门接大气，第二通气阀门可开闭；汇流管，第一检测阀门接入汇流管，第二检测阀门接入汇流管；传感器，汇流管与传感器的检测端连接。
在本申请的实施例的技术方案中，可以通过第一接口、第二接口连入待测设备的不同气路。每个气路均连接一个三通阀，每个三通阀均有一个接大气的阀门，接入接口的阀门和接入检测设备的阀门，接入检测设备的阀门通过汇流管后连接到检测设备，如传感器。当需要对不同的气路进行检测时，控制阀门保证待测气路对应的三通阀的接大气的阀门关闭，其他气路接大气的阀门打开。这样就能测得当前气路的气压是否正常。上述方案通过汇流管集气巧妙地实现了利用一个传感器进行待测设备的气路流量检测的技术效果。
在本方案的一个方面，第一接入阀门和第一检测阀门的通径相等。通过设计第一接入阀门和第一检测阀门的通径相等，可以保证三通阀内的气流稳定性，避免了气流进出流量不等造成的压力变化，保证检测数据的精确与稳定。
在本方案的另一个方面，汇流管的通径为第一检测阀门的通径的5倍以上。通过将汇流管的通径进行增大，避免了检测工装工作时多个通 路气体汇流后的冲击，保证气体流动稳定性，减少汇流管中的气体扰动。从而提高测量精度。
在本方案的另一个方面，汇流管包括汇流腔，汇流腔的通径为所述第一检测阀门的通径的5倍以上。通过在汇流管中专门设置一个大通径的汇流腔，能够减少多个通路气体汇流后的冲击，保证气体流动稳定性，减少汇流管中的气体扰动。从而提高测量精度。
在本方案的另一个方面，包括多个接口，包括至少与接口数量相同的三通阀，其中三通阀均分别包括接入阀门、通气阀门和检测阀门，各三通阀的接入阀门用于接入与其对应的接口、各三通阀的通气阀门用于接入大气且可开闭，各三通阀的检测阀门用于接入汇流管。通过设置多个接口和多个三通阀，能够使得检测组件能够同时对接更多的待测设备的负压口，提升检测的效率。
在本方案的另一个方面，包括控制单元，控制单元用于控制各三通阀的通气阀门的开闭。各三通阀在通气阀门开启的情况下，可以直通大气，检测阀门无法工作。通过控制单元控制各三通阀的通气阀门的开闭，可以实现不同的检测阀门的工作状态的切换。实现多个气路检测的分时复用效果。
在本方案的另一个方面，还包括负压表，负压表与传感器的检测端连接。负压表连接到检测端，则汇流管的气体还可以连接到负压表检测负压。达到显示气路的负压数值的技术效果。
在本方案的另一个方面，包括箱体，箱体内设置有如上述的检测组件。通过箱体装载检测组件，能够将检测组件的各部件都相对箱体固定，能够起到保护部件防止毁坏的技术效果，同时箱体进行统一封装还能够方便携带。
在本方案的另一个方面，箱体的箱体壁上还包括开口、导气管，开口通过导气管连接到接口上。通过设置开口和导气管，能够使得不同接口的工作位点对应不同的开口，在实际使用的时候，开口上可以连接与待测设备的不同接口的连接管，将连接管按照对应关系接好，就能够依次进行待测设备的不同接口的测量工作。通过上述方案便可以方便用户进行与待测设备的对接。
在本方案的另一个方面，箱体内设置有两组以上的检测组件。每组检测组件是多个接口接多个三通阀接同一个传感器，从而起到节省传感器的技术效果，最多同时一个传感器可以接24个接口和24个三通阀。在同一个箱体内，还可以设置2至3组的检测组件，则同时可以处理几十个接口的检测任务，大大提升了检测工装的检测效率。

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，以及军事装备和航空航天等多个领域。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。
本申请实施例公开的电池单体可以但不限用于车辆、船舶或飞行器等用电装置中。可以使用具备本申请公开的电池单体、电池等组成该用电装置的电源系统，这样，有利于缓解并自动调节电芯膨胀力恶化，补充电解液消耗，提升电池性能的稳定性和电池寿命。
本申请实施例提供一种使用电池作为电源的用电装置，用电装置可以为但不限于手机、平板、笔记本电脑、电动玩具、电动工具、电瓶车、电动汽车、轮船、航天器等等。其中，电动玩具可以包括固定式或移动式的电动玩具，例如，游戏机、电动汽车玩具、电动轮船玩具和电动飞机玩具等等，航天器可以包括飞机、火箭、航天飞机和宇宙飞船等等。
在二次电池的制作过程中，尤其是制作锂离子二次电池的过程中，需要对电解液进行处理。申请人注意到，在电解液的提取、化成的过程中，负压工装需要产生负压对电解液进行吸取，因此，负压的大小是影 响电解液吸取量的重要因素。而检测产生负压的负压工装的负压性能的检测工装的设计显得尤为重要。现有的检测工装通常在检测口上直接连上传感器，每个检测口均布置至少一个传感器。这种设计方式既不科学，也不经济，尤其是在芯片涨价大背景下的当下，会急剧提升检测工装的生产成本。因此，如何实现传感器的一对多复用就成了亟待解决的问题。
申请人为了解决上述问题，请参阅图1以及图2，提供了一种检测组件，包括，接口1、第一三通阀21、第二三通阀22、汇流管3以及传感器4。接口1的一端用于接入待测设备，接口1包括第一接口11、第二接口12。
第一三通阀21包括第一接入阀门211、第一通气阀门212和第一检测阀门213，第一接口11的另一端与第一接入阀门211连接，第一通气阀门212接大气，第一通气阀门212可开闭。
第二三通阀22包括第二接入阀门221、第二通气阀门222和第二检测阀门223，第二接口12的另一端与第二接入阀门221连接，第二通气阀门222接大气，第二通气阀门222可开闭。
第一检测阀门213接入汇流管3，第二检测阀门223接入汇流管3。汇流管3与传感器4的检测端连接。
接口1通常为中空的管路，可以与待测设备的负压吸嘴连接，当设备有多个待测的负压吸嘴时，可以设置多个对应的接口1。本实施例中，接口1至少包括第一接口11，第二接口12。还可以包括更多接口。第一接口11和第二接口12仅为示例展示与三通阀2的连接关系。
三通阀2指阀体有一个旁路的管路元件，通常设置为一进两出，三通阀2的各阀门可以设置为可独立地开闭。本实施例中的第一三通阀21的一进两出包括第一接入阀门211、第一通气阀门212和第一检测阀门213。其中第一接入阀门211接负压吸嘴时出气，第一检测阀门213进气。
本例中设置至少第二通气阀门222可开闭。三通阀2的材质可以选用金属、塑料等，阀门可以采用电磁阀等手段控制其开闭。
汇流管3是多进单出的管路元件，能够起到汇集流体和平衡缓冲压力的效果。汇流管3的材质可以选用铝、铁、钢、合金等材质制作。
传感器4通常为能够检测流体的传感装置，如流量计、压力传感器等，在检测到汇流管3的气流有所变化的时候，则能够给出响应信号。
流量计，现已广泛应用于石油天然气、石油化工、水处理、食品饮料、制药、能源、冶金、纸浆造纸和建筑材料等行业。又分为有差压式流量计、转子流量计、节流式流量计、细缝流量计、容积流量计、电磁流量计、超声波流量计等。按介质分类：液体流量计和气体流量计。将传感器4选用为流量计，则可以在汇流管3的气流有所变化的时候，则能够给出气流量变化的响应信号。
压力传感器，如气压传感器，用于测量气体的绝对压强的仪器，主要适用于与气体压强相关的物理实验，如气体定律等，也可以在生物和化学实验中测量干燥、无腐蚀性的气体压强。高精度气压传感器一般是利用MEMS技术在单晶硅片上加工出真空腔体和惠斯登电桥，惠斯登电桥桥臂两端出电压与施加的压力成正比，经过温度补偿和校准后具有体积小，精度高，响应速度快，不受温度变化影响的特点。输出方式一般为模拟电压输出和数字信号输出两种，其中数字信号输出方式由于和单片机连接方便，是目前应用的主流。将传感器4选用为压力传感器，则可以在汇流管3的气流有所变化的时候，则能够给出气压绝对值变化的响应信号。……
在本申请的实施例的技术方案中，可以通过第一接口11、第二接口12连入待测设备的不同气路。待测设备的气路正常状态下是能够产生负压的负压吸嘴，每个气路连接到接口1后均连接一个三通阀2，每个三通阀2均有一个接大气的阀门，接入接口1的阀门和接入检测设备的阀 门。接入检测设备的阀门通过汇流管3后连接到传感器4。
当需要对不同的气路进行检测时，控制阀门保持待测气路对应的三通阀2的接大气的阀门关闭，其他气路接大气的阀门打开。如果待测设备的气路能够产生负压，则三通阀2内气压就会降低，传感器4中就会有气流经过。这样就能测得待测设备的当前气路的气压是否正常。当需要切换检测的气路时，切换与检测气路对应的三通阀2的接大气的阀门关闭，则当切换后的气路能够正常工作时其对应的三通阀2的气压就会降低。
通过上述的检测组件，可以通过汇流管3集气，巧妙地实现了利用一个传感器4进行待测设备的气路流量检测的技术效果。
在本方案的一些实施例中，这里请看图1，第一接入阀门211和第一检测阀门213的通径相等。在工作的时候，三通阀2接大气的阀门关闭，则第一接入阀门211和第一检测阀门213工作，通过设计第一接入阀门211和第一检测阀门213的通径相等，则第一接入阀门211的气流大小等于第一检测阀门213的气流大小。
上述设计可以保证三通阀2内的气流稳定性，避免了气流进出流量不等造成的压力变化，保证检测数据的精确与稳定。
在本方案的另一些实施例中，请继续参照图1，汇流管3的通径为第一检测阀门213的通径的5倍以上。在实际的应用例中，可以将第一检测阀门213的直径设置为5mm，汇流管3的最大通径设置为25mm以上。第一检测阀门213的气流流入汇流管3后，流速降低，则扰动继续降低。在优选的实施例中，第一检测阀门213的直径约6mm，汇流管3的最大通径可以设置在60mm，即约10倍的第一检测阀门213的通径。更大的通径倍率能够更大程度地减少扰动，提高测量精度。通过将汇流管3的通径进行增大，避免了检测工装工作时多个通路气体汇流后的冲击，保证气体流动稳定性，减少汇流管3中的气体扰动。从而提高测量精度。
在本方案的一个进一步的实施例中，汇流管3包括汇流腔31，汇流腔31的通径为所述第一检测阀门213的通径的5倍以上。在实际的应用例中，可以将第一检测阀门213的直径设置为5mm，汇流管3的汇流腔31腔体部分设置为圆柱形，圆柱形的圆直径为25mm以上。汇流管3的其他管路，例如用于连接汇流腔31和检测端之间的管路，可以设置为与第一检测阀门213的直径相当即可。第一检测阀门213的气流流入汇流管3后，流速降低，则扰动继续降低。在优选的实施例中，第一检测阀门213的直径约6mm，汇流管3的汇流腔31腔体部分设置为圆柱形，圆柱形的圆直径为60mm，即约10倍的第一检测阀门213的通径。设置更大的通径倍率的汇流腔31能够更大程度地减少扰动，提高测量精度。
通过在汇流管3中专门设置一个大通径的汇流腔31，则其他汇流管3管路的通径尺寸设计要求就可以降低。上述方案能够减少多个通路气体汇流后的冲击，保证气体流动稳定性，减少汇流管3中的气体扰动。从而提高测量精度。
在本方案的其他一些实施例中，还可以设置包括多个接口1，这里请继续参阅图1，包括至少与接口1数量相同的三通阀2，其中三通阀2均分别包括接入阀门、通气阀门和检测阀门，各三通阀2的接入阀门用于接入与其对应的接口1、各三通阀2的通气阀门用于接入大气且可开闭，各三通阀2的检测阀门用于接入汇流管3。多个接口1、三通阀2的设置规律同上述的2个接口1、2个三通阀2的设置方式。接口1与待测设备的负压吸嘴连接，当设备有多个待测的负压吸嘴，可以设置多个对应的接口1。每个接口1的另一端对接相应的三通阀2的接入阀门，相应的三通阀2的通气阀门接大气，检测阀门均接入汇流管3，通过汇流腔31最终连接到传感器4。
多个接口1和多个三通阀2的工作模式也与两个接口1的工作模 式类似，多个接口1可以依次工作，当需要对不同的气路进行检测时，控制阀门保证待测气路对应的三通阀2的接大气的阀门关闭，其他气路接大气的阀门打开。如果待测设备的气路能够产生负压，则三通阀2内气压就会降低，流量计中就会有气流经过。这样就能测得待测设备的当前气路的气压是否正常。当需要切换检测的气路时，还是改成切换后的气路对应的三通阀2的接大气的阀门关闭，则当切换后的气路能够正常工作时其对应的三通阀2的气压就会降低。在通过设置多个接口1和多个三通阀2，能够使得检测组件能够同时对接更多的待测设备的负压口，提升检测的效率。
在本方案的另一些实施例中，这里请看图1及图3包括控制单元6，控制单元6用于控制各三通阀2的通气阀门的开闭。各三通阀2在通气阀门开启的情况下，可以直通大气，检测阀门无法工作。控制单元6可以协调各气路的工作顺序，例如控制单元6通过编程写好分时复用的程序控制不同的三通阀2的通气阀门的依次启动。在另一些实施例中，控制单元6还可以接收待检测设备的不同的负压吸嘴的启动信号，根据接收到的启动信号控制检测组件中对应的三通阀2的工作，如闭合该三通阀2的通气阀门，开启其他三通阀2的通气阀门。通过控制单元6控制各三通阀2的通气阀门的开闭，可以实现不同的检测阀门的工作状态的切换。实现多个气路检测的分时复用效果。
在本方案的另一个实施例中，请继续参见图1，还包括负压表5，负压表5与传感器4的检测端连接。负压表5又称为真空压力表，以大气压力为基准，用于测量小于大气压力的仪表。真空压力表适用测量无爆炸，不结晶，不凝固，对铜和铜合金无腐蚀作用的液体、气体的真空压力测量。广泛应用于气体输送，管道液体及密闭容器中测量无腐蚀性、无爆炸危险、无结晶体、不凝固体的各种液体、气体、蒸汽等介质的压力大 小，如各种工业自控环境，涉及石油管道、水利水电、铁路交通、智能建筑、生产自控、航空航天、军工、石化、油井、电力、船舶、机床、管道送风、真空设备等众多行业。
通过使用负压表5连接到检测端，则汇流管3的气体还可以连接到负压表5检测负压。达到显示气路的负压数值的技术效果，根据控制模块切换对应的气路，能够进一步达到检测不同负压吸嘴的具体负压值的技术效果。
为了更好地搭载检测组件进行检测工作，在另一些实施例中，包括箱体7，箱体7内设置有上述任一实施例中的检测组件。这里的箱体7用于进行封装，有一定的形状，如长方体、正方体、圆柱体等等。某些实施例中，箱体7的内部可以设置有双气路/双三通阀2的检测组件，通过箱体7携带就可以同时检测2个待检测设备的负压吸嘴是否能够正常工作。箱体7还可以搭载三个以上气路和三个以上三通阀2的检测组件，通过箱体7携带就可以同时检测多个个待检测设备的负压吸嘴是否能够正常工作。
通过箱体7装载检测组件，能够将检测组件的各部件都相对箱体7固定，能够起到保护部件防止毁坏的技术效果，同时箱体7进行统一封装还能够方便携带。
在本方案的另一些实施例中，箱体7的箱体壁上还包括开口71、导气管，开口71通过导气管连接到接口1上。这里，开口71可以是箱体壁上的孔、洞。开口71在对外设置上主要用于对接待检测设备，例如对接待检测设备的负压吸嘴，开口71对内可以用于对接不同的接口1，例如通过导气管与检测组件的接口1连接。其他一些实施例中，导气管的一端连接在接口1上，另一端可以直接穿过开口71，联通到待测设备上，也可以仅仅是接到开口71上。
通过设置开口71和导气管，能够使得不同接口1的工作位点对应不同的开口71，在实际使用的时候，更方便用户的手动操作对接。开口71上可以连接与待测设备的不同接口1的连接管，将连接管按照对应关系接好，就能够依次进行待测设备的不同接口1的测量工作。通过上述方案便可以方便用户进行与待测设备的对接。开口71上还可以设置条码、编号等提示信息，用于提示用户防止对接错误。
在本方案的其他一些实施例中，请继续参阅图2，箱体7内设置有两组以上的检测组件。每组检测组件是多个接口1接多个三通阀2接同一个传感器4，从而起到节省传感器4的技术效果，最多同时一个传感器4可以接24个接口1和24个三通阀2。在同一个箱体7内，还可以设置2至3组的检测组件，则同时可以处理几十个接口1的检测任务，综上述，设计多组检测组件可以大大提升检测工装的检测效率。
根据本申请的一些实施例，请参阅图1至图3，本申请提供一种检测组件，包括至少两个接口1和两个三通阀2，三通阀2的接入阀门21连接接口1，三通阀2的通气阀门22接大气，通气阀门22还受到控制单元6的控制开闭，三通阀2的检测阀门23接汇流管3，汇流管3设置有一个大通径的汇流腔31，然后接入到传感器4和负压表5中，传感器4和负压表5与控制单元6通信连接，控制单元6还可以连接待检测设备，同步控制待检测设备和通气阀门22。还可以在检测组件外设置箱体7来构成便携的检测工装，箱体上设置有开口71用以对接待检测设备。以上设置的检测组件达到了传感器4一对多检测接口1的效果。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修 改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围，其均应涵盖在本申请的权利要求和说明书的范围当中。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本申请并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
