Description

多片式模组电极连接切断装置 技术领域
本发明涉及电池技术领域，特别是一种用于对退役后动力电池模组的电极连接进行切割的切断装置。
背景技术
出于节能环保考虑，对于退役后的动力电池，其梯次利用越来越受到重视。但是退役后能够直接进行梯次利用的模组很少，而以电池单体的形式利用居多，所以通常都是先将电池模组拆解成单体再进行梯次利用的。为了将模组拆解成单体，其必要的一环是将模组上的铝极片铣削掉，以切断单体间的机械连接，同时也使每个分离出来的单体电极表面平整以利于后续的梯次利用。
然而在铣床上对模组直接用铣刀进行铣削时，具体当铣刀在经过相邻的两个单体的正、负极间的空隙时，因铣刀自身会将其正负电极产生电连接，在铣刀与极片之间形成短路而产生火花，容易导致铣刀切削韧退火而立即报废，甚至会产生火灾安全隐患。为了铝极片铣削工序的安全，需要对模组极片进行预处理，具体先将模组一侧的铝极片断开(以下简称断极)，这样在对另一侧铣削铝极片时，就不构成回路避免出现短路。
目前对于断极工序采用的方法是对极片连接的拱形处，用人力使用工具(钳子、铲子、角磨机等)断开。人力操作速度慢、劳动强度大，而且断极的效果也不好，断极后的形状不规则，不利于后续极片在铣床上的铣削，同时人力撬断极片对电池电极的本身有时也会造成损害；此外，手持角磨机进行切割断极的效率不够高，而且因为其采用的砂轮片一般为树脂锯片(不能用金属锯片，原因是金属锯片在切削金属时，反作用力大，手持时不小心会把持不住而导致旋转的角磨机伤人)，树脂锯片是消耗性配件，切削时很快出现自身磨损而需经常更换锯片，故也影响工作效率和增加作业费用。
发明内容

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。为透彻的理解本发明创造，在接下来的描述中会涉及一些特定细节。而在没有这些特定细节时，本发明创造仍可实现，即所属领域内的技术人员使用此处的这些描述和陈述向所属领域内的其他技术人员可更有效的介绍他们的工作本质。此外需要说明的是，下面描述中使用的词语“前侧”、“后侧”、“左侧”、“右侧”、“上侧”、“下侧”等指的是附图中的方向，词语“内”和“外”分别指的是朝向或远离特定部件几何中心的方向，相关技术人员在对上述方向作简单、不需要创造性的调整不应理解为本申请保护范围以外的技术。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定实际保护范围。而为避免混淆本发明创造的目的，由于熟知的制造方法、控制程序、部件尺寸、材料成分、管路布局等的技术已经很容易理解，因此它们并未被详细描述。
图1是本发明一个实施方式的立体图，参照图1，本发明的一个实施方式提供了一种多片式模组电极连接切断装置，包括机座100，机座100上设置有工作台200，工作台200连接有调高装置300。调高装置300用于控制工作台200调节高度，以匹配不同高度的电池模组。而工作台200用于固定待断极处理的电池模组。
进一步的，参照图2、图3，多片式模组电极连接切断装置还包括有角磨装置400，角磨装置400包括有光轴410、角磨机420，角磨机420设置在光轴410上，角磨机420上设置有锯片421。
分布在光轴410上的角磨机420具体数目根据模组700上的电极701数目而定(参照图5)，具体作用是将角磨机420的锯片421同时对模组的电极701(连接片)进行断极切割，以达到快速安全地切断电路连接的目的。
回收企业接收的退役模组，种类繁多、尺寸各异，但同种型号的模组数量却十分有限，故要求多片切断机必须适应不同种类的模组700，否则若只适用于一种或少数几种模组700。而新设计的角磨机420就可以顺着光轴410移动调整位置，匹配不同的退役模组。
再进一步的，工作台200上设置有平移进给装置，用于控制工作台200平移活动。在实际工作时，通过平移进给装置控制工作台200平移进给，就可以使角磨机420靠近模组700并把模组700的电极701(连接片)切断，完成断极步骤。
采用机械夹装切割而不用原来的手持角磨机，角磨机的锯片421就可以采用适合切割铝合金的锯片，取代了树脂锯片，从而降低了使用费用和更换锯片的次数，显著提高了工作效率。
以上公开的一种多片式模组电极连接切断装置所揭露的仅为本实用新型较佳的实施方式，仅用于说明本实用新型的技术方案，而非对其限制。本领域的普通技术人员应当理解，其依然可以对前述的技术方案所记载的技术方案结合现有技术进行修改或者补充，或者对其中部分技术特征进行等同替换，例如平移进给装置可设置在角磨装置400上控制角磨装置400移动；而这些修改或替换，并不使相应的技术方案的本质脱离本实用新型的实施方式技术方案的精神和范围。
以下结合一些实施例进行说明，其中此处所称的“实施例”是指可包含于本申请至少一个实现方式中的特定特征、结构或特性。在本说明书中不同地方出现的“实施例中”并非均指同一个实施例，也不是单独的或选择性的与其他实施例 互相排斥的实施例。此外，表示一个或多个实施例的细节并非固定的指代任何特定顺序，也不构成对本发明创造的限制。
实施例1，角磨机420上设置有角磨机固定架430，角磨机固定架430包括有方管431和角磨机滑块432，角磨机420插接入方管内，角磨机滑块432套装在光轴410上，方便角磨机420的固定，既适合专门研发的角磨机420，也适合市面上通用的角磨机420。
本实施例中，可选地，其中，角磨机420用4个螺丝将其固紧在方管431上。
本实施例中，可选地，为了防止角磨机420在光轴410上移位，可通过五花螺钉将角磨机420固定在光轴410上使之不移位。
实施例2，光轴410顺着左右侧方向延伸，一个角磨机420对应的光轴410至少有两根，且光轴410顺着上下侧方向排列，避免角磨机420在光轴410摇晃、偏移错位。
实施例3，光轴410包括有若干组，每组光轴410对应若干个角磨机420，各组光轴410顺着前后侧方向排列。
由于手持式角磨机自身的宽度一般为60毫米，若考虑角磨机的装夹，两台角磨机的圆锯片间距最小约70毫米，为了可以切割单体间距小的模组700(即d值小)，本技术可采用多排、间隔布置角磨机的方式，从而解决了对小间距模组极片切断的问题。现以两排布局为例(见图2)，当第二排与第一排间隔布置时，圆锯片的最小距离就会由d降到d/2，于是模组700的单体最小间距不小于35毫米即可实现切割，这个间距可以适应大多数的模组700了。
若当d小于35时则两排布局无法满足要求，解决的方法是采用三排并列布置，则最小圆锯片间距的距离可以达到d/3＝23.3毫米。可见，这个间距几乎可以覆盖所有的模组700了。
实施例4，角磨装置400包括有光轴框440，光轴410设置在光轴框440内。
本实施例中，光轴框440内安装了2排光轴410，每排光轴410共2根
实施例5，机座100上设置有龙门架110，角磨装置400设置在龙门架110上。
实施例6，参照图4，机座100上设置有纵向导杆510，纵向导杆510上设置有纵向平移架500，纵向平移架500可顺着纵向导杆510前后平移。
纵向平移架500上设置有横向导轨610，横向导轨610上设置有横向平移架600，工作台200设置在横向平移架600上，横向平移架600可顺着横向导轨610左右平移。
调高装置300设置在工作台200与横向平移架600之间。
实施例7，工作台200上设置有L字形固定板210，工作台200上设置有可活动的夹紧板220。
本实施例中，可选地，为了能夹紧模组700使之在断极过程中固定不动，在工作台200的下面安装有双轴气缸，双轴气缸通过其上安装的夹紧板220对模组700进行夹紧与松开。
实施例8，调高装置300包括有调高螺杆310和升降导杆320，使工作台200始终能稳固地在平行于操作台的方向上进行平行移动，从而保证模组700与上面的角磨机圆锯片相对位置的精度，也就是保证切割精度。
实施例9，纵向平移架500上设置有纵向平移油缸520。即纵向平移油缸520作为平移进给装置，在具体工作时，通过纵向平移油缸520控制工作台200平移实现进给步骤，而角磨机420则不需要移动，即可完成断极步骤。
纵向平移架500上设置有梯形丝杆620，梯形丝杆620上设置有手摇轮621，梯形丝杆620上设置有梯形螺帽，梯形螺帽与横向平移架600连接。操作人员通过摇动手摇轮621即可通过驱动梯形螺帽沿着左右侧方向运动，继而使中平板沿着左右侧方向移动。
实施例10，定义左右侧方向为X轴，定义前后侧方向为Y轴，定义上下侧方向为Z轴。
多片式模组电极连接切断装置的机座100上沿着Y轴方向放置两根平行的纵向导杆510，每根导向轴通过两个固定座用螺丝固定在操作台上，每根导向轴上装有2个直线轴承，这4个直线轴承与纵向平移架500通过螺丝连接在一起。
在纵向平移架500的上面沿着X轴方向平行放置两根横向导轨610，每个直线导轨上有两个滑块，四个滑块通过螺丝与横向平移架600固连。
横向平移架600上装有4个垂直的升降导杆320，升降导杆320的下端通过支座用螺丝与横向平移架600固连，每个升降导杆320的另一端装设滑动轴承，4个滑动轴承通过螺丝固装在工作台200上。
工作台200、横向平移架600、纵向平移架500从上到下排列分成上、中、下三层。
工作台200上焊接有L字形固定板210，用于定位工件(模组700)，在工作台200的下面安装有双轴气缸，双轴气缸通过其上安装的夹紧板对模组700进行夹紧与松开。
多片式模组电极连接切断装置的工作过程如下：
1、首先，将待断极的模组700置放在工作台200上，并靠紧在L字形固定板210上，然后打开气路使双轴气缸驱动夹紧板220夹紧模组700，使之保持固定。
2、用扳手拧动螺杆上的六角头，即可上下调整工作台200使之沿着Z轴移动，在四个立轴的导向下，即可将模组700固定在适合的高度位置，这个位置可以使圆锯片在高度上能够容易地切断模组700上连接极片的拱形部分；
3、通过摇动手摇轮，将模组单体间的拱形极片在X轴的方向上对准角磨机的圆锯片；
4、在调整好模组700在X、Z轴的位置后，即可操纵气路使气缸推动耳缘进而带动模组700在Y轴方向实现进给运动，由于事先已将6个角磨机420间的锯片421在X轴的方向上调整好，也即每个圆锯片正对着模组700的拱形极 片(电极701)处，而模组700的高度(即Z轴方向)也适合对圆锯片产生的断极，故一次在Y轴的进给过程中，会在模组700的一侧汇流排上进行了断极。
由于同种类的模组700的尺寸误差不大，基本在0.5毫米以内，所以对同一批模组700，一旦将X轴、Z轴调整好后，以后的断极过程中，即可不用调整，而直接操作1、4步骤即可。
根据上述原理，本发明还可以对上述实施方式进行适当的变更和修改。因此，本发明并不局限于上面揭示和描述的具体实施方式，对本发明的一些修改和变更也应当落入本发明的权利要求的保护范围内。
实践证明，新技术与原有技术相比，具有以下优势：
1.匹配市面上广泛销售的手持式角磨机，相比于非标制作的圆锯片切割装置，角磨机不但在价格上显著低于自制件，同时在性能和可靠性上，也显著优于自制件，原因是：成熟的、大批量的通用设备，比起自制的、专用的非标定制设备来说，其优势是众所周知的；
2.在日后的维护保养中，切割部分自然是维护的重点，而一台角磨机即便是整体更换，一台也就几百元钱，但专用自制设备维修起来，要成数倍的增加，同时更换角磨机方便快捷，而更换专用设备则要复杂的多。
