Description

将阳极帽超声波密封到电化学电池衬圈上的方法
发明领域
本发明涉及盖如电化学电池的阳极帽用超声波设备密封到衬圈上，得到特别适合于密封容器如电化学电池用容器的盖-衬圈组合件。
发明背景
电子设备的小型化需要有小型且强力的电化学电池。已知使用碱性电解质的电池每单位体积有高的能量密度，所以特别适合用于小型电子设备，如助听器、钟表和计算器。但是，碱性电解质如氢氧化钾和氢氧化钠水溶液易于润湿金属表面，并已知它们易于通过电化学电池的密封金属界面渗漏。如此的渗漏使电解质溶液从电池中损耗掉，并且还可使腐蚀性沉积物在电池表面出现，因而有损于电池的外观和销售性。这些腐蚀性盐也可损坏放有电池的设备。存在这一问题的代表性电池体系包括氧化银-锌电池、镍-镉电池、空气去极化电池和碱性二氧化锰电池。
使用电解质的电池中，如果电解质从电池中漏出，那么在原电池中使用的许多种液体电解质都会在电池的外表面上形成腐蚀性盐沉积物。这样的腐蚀性沉积物有损于电池的外观和销售性。这些腐蚀性沉积物还可损坏放有电池的电子设备以及缩短电池寿命。所以，将这样的原电池密封以防止电解质渗漏。
在先有技术中，传统的方法是在电池容器和盖之间加绝缘衬圈，以便使电池密封。通常，衬圈必须由对装在电池中的电解质和电池环境是隋性的材料制成。另外，衬圈必须是柔软的，在密封压力下抗冷流动以及保持其特性，以便确保在长期贮存过程中完全密封。已发现对于大多数应用来说，许多材料如尼龙、聚丙烯、乙烯-四氟乙烯共聚物和高密度聚乙烯都适合作衬圈材料。通常，绝缘衬圈呈“J”形结构，伸长的盖壁插入其中，以致当完全挤压时，衬圈的底部对容器壁的底部形成“U”形密封。为了更好地确保良好的密封，通常将密封剂沉积在“J”形密封中，以致当盖插入衬圈时，伸长的盖壁的棱边将置于密封剂中，然后当进行完全挤压时，衬圈将对伸长的盖壁的底部产生压缩。因此密封剂将进一步对盖-衬圈组合件密封。另外，密封剂还起缝隙填充剂的作用，以弥补衬圈和盖部件制造差异。有可能衬圈和盖的理想部件尺寸的偏差可使有效的电池材料和/或电解质堵在盖壁棱边和密封剂之间。这就可能使电池渗漏。因此，因为衬圈-盖组合件各部件难以按精确的技术规格制造，以及难以将密封剂连续准确涂到衬圈上，所以组装好的电池总是有可能会渗漏。小型电池特别是这样。
本发明的一个目的是提供一种生产良好的电化学电池的衬圈-盖密封组合件的方法。
本发明的另一目的是提供一种用超声波设备生产良好的电化学电池如碱性电池的衬圈-盖密封组合件的方法。
本发明的另一目的是提供一种用超声波设备生产碱性电池的衬圈-盖密封组合件的有效且低成本方法。
本发明上述的目的以及另外一些目的从以下的说明和附图将变得十分明显。
发明内容
本发明涉及一种用超声波方法将盖密封法在衬圈上的方法，该法包括以下步骤：
(a)制得可压缩的衬圈，它有其一端有向内伸长的突边的管状壁；
(b)制得有向下伸长的壁的盖，有底部棱边；
(c)将所述的盖插到所述的衬圈中，以致盖壁的底部棱边与衬圈的突边接触；以及
(d)用超声波方法强制使盖进入衬圈的突边中，一直到衬圈壁的突边和底部对盖壁的底部形成U形包封。
用于本文中的术语管状的指圆形，椭圆形，正方形、长方形或任何多边形管状壁。
超过能听度的频率弹性波称为超声波。这些超声波通常用石英晶体振荡器产生，它用于产生200-30千周/秒或更高范围的频率。这些超声波可用来对物体产生稳定的作用力。这种力在本发明中用于使伸长的盖壁插入到衬圈的突边中，在衬圈和盖的底壁之间产生极好的密封。施加的使盖壁的底部插入衬圈突边的力必须足以使衬圈对盖壁的底部形成“U”形密封。因此，超声焊接器的设定必须视盖的材料和衬圈的组成来调节。一旦选定了这些数据，就可用传统的超声焊接器使盖的底壁插入衬圈的突边中。
优选的是，平行于衬圈壁纵轴测定的突边的厚度应比衬圈壁的厚度要厚，以致盖壁的棱边可容易用超声波设备强制插在所述的突边内。优选的是，突边厚度应至少比衬圈壁的厚度厚1.5倍，更优选至少比衬圈壁的厚度厚3倍。优选的是，应将盖的棱边插入衬圈至少0.01英寸，更优选至少0.015英寸，以确保良好的密封。应当理解，棱边插入突边的距离取决于衬圈-盖部件的材料组成，以及在某些应用中还取决于使用衬圈-盖组合件的电池体系。在某些应用中，可将密封剂用于盖壁的棱边和衬圈的突边之间。一旦制成衬圈-盖组合件，优选将电池的阳极安装在衬圈-盖组合件中，然后将衬圈-盖-阳极组合件放在装有电池体系的其他有效和无效组分的电池容器中。然后将容器对衬圈-盖组合件挤压，形成电池密封。具体地说，可通过将容器侧壁的上部拧在衬圈的外竖立壁上，将衬圈-盖组合件密封到电池的容器上，因此压缩容器和盖之间的衬圈，以致有效的使所述的盖与所述的容器密封并使它们之间电绝缘。
本发明的密封衬圈含有考虑其在电解质存在下的稳定性、弹性变形性以及抗冷流动性而选择的材料。适合的聚合物材料选自尼龙、聚四氟乙烯，氟化的乙烯-丙烯，乙烯与氟化的乙烯-丙烯的共聚物，三氟氯乙烯，全氟烷氧基聚合物，乙烯基聚合物，聚乙烯，聚丙烯，聚苯乙烯等。熟悉本专业的技术人员可识别出其他适合的材料。在某些应用中，可与本发明的衬圈一起使用另外的预防措施来达到有效的密封，如用粘合剂如脂肪聚酰胺树脂涂覆衬圈突边表面。本发明的密封衬圈适合于各种生产技术如注塑。衬圈突边表面结构很适合于从模具、冲头等取下。优选的是，衬圈为尼龙。盖可由蒙乃尔合金、铜、电镀不锈钢或其他导电材料制成。优选的是，盖为由镍、不锈钢和铜制成的三镀层材料盖。但是，盖应由当与电池中的材料接触时不腐蚀或不损坏的导电材料制成。电池的容器可由不锈钢、铁、镍、镀镍的钢或其他一些导电材料制成。
本发明可使用的代表性电池体系是碱性二氧化锰电池、空气去极化的电池、镍-镉电池和氧化银-锌电池。
附图的简单说明
结合附图一起考虑，本发明从以下的描述将变得很明显，这些附图示例性地说明本发明实施方案，并不打算以任何方式来限制本发明，其中：
图1是用于本发明的圆柱形衬圈的截面图。
图2是用于本发明的阳极盖的截面图。
图3是插入图1的衬圈的图2的盖的截面图。
图4是盖的底部棱边用超声波法插入衬圈的突边后的图3衬圈-盖组合件的截面图。
图5是组装在碱性电池中的图4衬圈-盖组合件的截面图。
附图的详细说明
图1为圆柱形衬圈2，有竖立壁4，末端有向内伸出的突边6。突边6的厚度X比竖立壁4的厚度Y要厚。图2为阳极帽8，它有顶盖10和伸长的圆柱形侧壁12。该阳极帽8示为一种材料，但优选由两层或多层不同材料制成，最优选为镍、不锈钢和铜的三镀层材料。
图3为插入图1的衬圈2中的图2盖8，以致盖8的底部棱边16在突边6上。图4为用超声方法使盖8的棱边16强制进入突边6后嵌入突边6的盖8的棱边16。正如从图4可看出的那样，突边6对盖的棱边16形成“U”形密封包层。如果需要的话，可将密封剂填在棱边16和突边6之间。另外，为了便于将棱边16插入突边6，可将盖8的棱边16弄尖成钝的棱面。按衬圈的纵轴测量，锥度优选小于45°，更优选在15°和30°之间。
图5表示一锌空气电池19，其中电池19最大的部件是称为阴极杯的开口的金属容器20。阴极杯20通常由镀镍的钢制成，它按这样成型，以致有相当平的中心区22，中心区22与相同高度的竖立壁24相连，并被它围绕。两个小孔26穿过杯20的底22，作为空气进口。多孔材料层28覆盖空气孔26的内表面，作为分配膜28。聚四氟乙烯层30覆盖在包括空气分配膜28在内的阴极杯20的整个底部。第二个主要部件是空气电极32，它在聚四氟乙烯层30的内表面附近。该电极32有几个部件：包括金属网34；埋在网34的二氧化锰和碳的混合物；隔膜36，它防止阳极电解质流入阴极32；以及全吸收分离器38。第三个部件是普通的帽形金属盖40，它构成电池的顶部，通常称为阳极帽*。在图5中，阳极帽40的棱边42按本发明用超声波方法插入衬圈46的突边44。阳极帽40可由有铜层48的层压材料制成，铜层48压到镀镍的钢条的裸露侧上。镍层50保护钢条52的外表面，钢条52在镍层50和铜层48之间，其他制作阳极帽的层压材料包括铜在不锈钢基材上的双层层压材制或三层层压材料。由层压金属条冲压的圆盘制成阳极帽。铜层构成阳极帽的内表面，并直接与阳极混合物接触。第四个部件是阳极混合物54，它可含锌粒、电解质和有机化合物如粘合剂和缓蚀剂的混合物，它构成电池的阳极。阴极杯20与插入的空气电极32和有关的膜一起倒过来压在阳极帽/衬圈组合件上，组合件按本发明预先组装并有阳极。在倒过来的同时，向内收集阴极杯20的棱边。阴极杯的壁56然后压向阴极杯20和阳极帽40之间的弹性衬圈46，从而产生密封和阳极帽40和阴极杯20之间的电绝缘。适合的胶带58可放在开孔26上，一直到电池备用。
以下实施例说明本发明的原理，而不打算用这些实施例来限制本发明的范围，本发明的范围在附后的权利要求中给出。
实施例
发现可用超声波焊接器将总高为0.163英寸的0.008英寸厚三镀层材料(镍、不锈钢、铜)直壁的阳极帽插入0.020英寸突边的(“J”形槽的)衬圈(等厚衬圈)大约0.006英寸。用手连接阳极帽和衬圈，并放在焊接器喇叭口下方，阳极帽面向喇叭口。然后施加压力和超声波，用限位挡块控制总的下降距离。这样得到阳极/衬圈组合件，其总高为0.177英寸，而不是正常的连接高度0.183英寸。焊接器为Brauson Welder Series 800 model 8400，有扁平喇叭口。为了使盖插入衬圈，焊接器的设定如下：
下降速度      6
压力          10psi
焊接时间      ＜0.2sec.
保压时间      0.3sec.
制动器设定    5
功率          100
锌空气电池用这一衬圈-盖组合件制造，有良好的密封特性。
然后制成模制的厚突边(0.040英寸)的衬圈。这些衬圈的突边厚度(X)比壁厚度(Y)要厚，X为0.040英寸和Y为0.010英寸。总高为0.174英寸的0.008英寸三镀层材料阳极帽与这些衬圈一起使用。发现用于0.020英寸衬圈的超声波焊接器的最初设定不能使帽插入。因此改变设定如下：
下降速度      6
压力          14
焊接时间      0.8sec.
保压时间      0.3sec.
制动器设定    5
功率          100
这些设定得到总高0.194英寸的阳极/衬圈组合件，表明插入为0.030英寸，在盖的棱边下方有效的衬圈突边厚为0.010英寸。在这一试验中观测到，衬圈的外衬圈直径可出现一些变形，为了排除这一变形，可用有所需衬圈外径的托架将衬圈固定，同时用超声波方法将盖插入衬圈。
从试验得到的数据证明(1)在衬圈和阳极帽之间可产生更好更准确的装配；(2)组合件的高度可维持和控制，(3)部件的公差变得不重要；(4)可用更容易地制造设备来生产“L”形衬圈；(5)由于盖更深的插入衬圈的突边使密封面积增加。
应当理解，在不违背本发明的精神和超出本发明的范围的条件下可对这些公开的本发明的优选实施方案作出各种改进和改变。
