技术领域
本申请涉及涂胶技术领域，尤其涉及一种用于生产电池的涂胶设备。
背景技术
在电池模组的生产过程中，电池模组内的多个电池与围框之间均需通过胶水进行粘接，一方面可以提升整个电池模组的安全性，另一方面还可以提升电池模组的散热效率。目前，在电池模组的组装过程中，通常先通过粘接效果较好的结构胶将多个电池以及两个端板连接起来，然后再对该半成品的电池模组进行绝缘测试，以及电量、电压等参数的测试。在通过结构胶粘接多个电池的过程中，需要以电池的极柱上表面为基准进行固定连接，这便于测试及后续焊接电池连接片的工序的进行，还可以保证电池模组的安全性。但是，由于在电池的高度方向上，不同电池之间存在尺寸公差，因而对于多个粘接后，且尺寸存在差异的电池而言，可能出现各电池底部不平齐的状况。目前，电池与底板之间涂胶量为定值，从而可能因底板上某些区域胶水不足，而出现胶水无法提供有效的粘接及散热效果，以及因某些区域胶水过量而出现溢胶的情况，这不利于提升整个电池模组的品质。

具体实施方式
下面通过具体的实施例并结合附图对本申请做进一步的详细描述。
在本申请的描述中，除非另有明确的规定和限定，术语“第一”、“第二”、“第三”、“第四”仅用于描述的目的，而不能理解为指示或暗示相对重要性；除非另有规定或说明，术语“多个”是指两个或两个以上；术语“连接”、“固定”等均应做广义理解，例如，“连接”可以是固定连接，也可以是可拆卸连接，或一体地连接，或电连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
本说明书的描述中，需要理解的是，本申请实施例所描述的“上”、“下”、“左”、“右”等方位词是以附图所示的角度来进行描述的，不应理解为对本申请实施例的限定。此外，在上下文中，还需要理解的是，当提到一个元件连接在另一个元件“上”或者“下”时，其不仅能够直接连接在另一个元件“上”或者“下”，也可以通过中间元件间接连接在另一个元件“上”或者“下”。
如图1-3所示，本申请实施例提供了一种涂胶设备，在电池模组6的组装过程中，此涂胶设备可以根据电池模组6内各电池的实际尺寸，灵活改变挤涂在电池模组6的底部上的胶水的量，以保证多个电池与底板7相互配合时不会出现缺胶或溢胶的情况，这可以提升电池模组6的整体品质。该涂胶设备包括机架1、涂胶机构2、模组测高机构3和胶量控制机构(图中未示出)。其中，涂胶机构2用于向待涂胶部件上挤涂胶水，其可以通过连接件安装在机架1上；模组测高机构3用于测量电池模组内多个电池之间的高度差。需要说明的是，为了便于测量工作的进行，待测量的电池模组6可以包括围框和多个电池，且未连接底板7。围框可以包括侧板和端板，二者之间可以采用焊接的方式固定连接，形成围框，多个电池之间，以及电池与端板之间均可以采用结构胶预先固定连接到一起，且为了保证 电池模组6使用可靠性，在涂抹结构胶之前，可以使多个电池的极柱上表面平齐设置，然后再通过结构胶连接。由于电池之间存在尺寸公差，因而多个电池的底部可能会出现参差不齐的情况，即，在电池模组6与底板7连接之后，各电池与底板7之间的距离不同，体现在模组测高机构3中则为：各电池的底面与围框底面(或端板底面)之间存在不同的尺寸差，因而，一种优选地具体实施例是，模组测高机构3包括围框支撑台31和高度测量部32，围框支撑台31具有支撑平面，前述支撑平面用于支撑电池模组6的围框，从而使得多个电池均以围框支撑台为基准进行高度差测量，高度测量部32用于测量各电池底面到围框支撑台31的距离，即各个电池之间的高度差。
由上可知，本申请所提供的涂胶设备中，安装于机架1上的涂胶机构2用于向电池进行涂胶，借助模组测高机构3可以对电池模组6中多个电池之间的高度差进行测量，并将测量结果输出至胶量控制机构，胶量控制机构可以根据前述高度差，对应控制涂胶机构2在向各个电池进行涂胶工作时的涂胶量，从而防止出现多个电池与底板7相互配合时，出现缺胶或溢胶的情况，提升电池模组的整体品质。
具体地，围框支撑台31可以为金属等硬质材料制成的平板状结构，且为了降低高度测量部32的工作难度，围框支撑台31可以设置成环状结构，可以通过环状结构支撑电池模组6的围框，以使电池模组6静置于围框支撑台31上，环状结构的围框支撑台31具有的中间缺口311可以使多个电池暴露出，高度测量部32即可设置在中间缺口311处，以对电池与围框支撑台31之间的尺寸差进行测量；高度测量部32具体可以为测距仪或测距传感器等。优选地，模组测高机构3还可以包括安装架36，围框支撑台31和高度测量部32均可以通过连接件连接在安装架36上，二者对应设置，以在电池模组6静置在围框支撑台31上之后，通过高度测量部32对电池模组6内的多个电池与围框支撑台31的顶面(或端板底面)之间的距离进行测定；在前述测定过程完成之后，模组测高机构3可以将测定结果传输至胶量控制机构，胶量控制机构可以根据前述测定结果灵活设计底板7上与各个电池对应的区域内的胶水需求量。例如，某一电池与围框支撑台31之间的距离较大，则该电池所对应的底板7的区域所需的胶 水的量相对较大，相反地，如果某一电池与围框支撑台31之间的距离较小，则底板7上对应区域的胶水需求量较小；具体地，胶量控制机构可以通过有线或无线传输的方式分别与模组测高机构3和涂胶机构2连接，实现传输信号，控制涂胶量的目的。
进一步地，如图2所示，可以采用弹性测高探针测量电池底面与围框支撑台31之间的距离，这种测距部件的结构简单，灵敏度相对较高，且成本较低；相应地，模组测高机构3内还可以设置有数模转换部33，以将弹性测高探针测得的尺寸值转换为电信号或其他通信信号，并输出至胶量控制机构；弹性测高探针设置成有多个，多个弹性测高探针与多个电池一一对应设置，以分别测量各电池底面与围框支撑台31之间的距离。具体地，弹性测高探针可以包括测量头、弹性件和主体，测量头通过弹性件与主体活动连接，多个弹性测高探针的测量头平齐且均凸出于围框支撑台31的上表面设置，本领域技术人员可以根据实际情况，灵活改变测量头伸出围框支撑台31的距离，以保证测量结果的准确性。优选地，多个高度测量部32可以呈直线均匀排布，多个高度测量部32之间的距离可以设置为定值，这可以进一步降低高度测量部32的安装难度，也可以在一定程度上提升测量结果的准确性；另外，多个高度测量部32均可以设置在围框支撑台31的中间位置处，即多个高度测量部32沿电池的排列方向居中设置在中间缺口311内，这可以防止某个电池在之前粘接连接的过程中因操作失误等原因而出现相对其他电池的偏斜，造成电池底面中两端位置处与围框支撑台31之间的距离误差较大，而通过测量电池底面的中间位置，即便电池存在偏斜情况，也几乎对测量结果的准确性无影响，从而防止因电池偏斜给测量结果带来不利影响。
在测量过程中，弹性测高探针向电池模组6施加一定的沿竖直向上的弹力，为防止前述弹力的存在影响测定结果的精确性，优选地，模组测高机构3还可以设置有压紧部34，压紧部34安装在围框支撑台31上，在对电池模组6进行测量的过程中，压紧部34可以向电池模组6施加一定的下压力，以防止电池模组6翘起或颤动等情况的发生而影响测量结果的准确性。具体地，压紧部34可以包括驱动件341和下压头342，驱动件341可以为驱动气缸或液压缸等，驱动件341可以固定在围框支撑台31上， 下压头342可以连接在驱动件341的驱动头上，从而在对电池模组6进行测量时，借助压紧部34可以向电池模组6施加下压力。可选地，下压头342可以与电池模组6的围框配合，以防止未连接底板7的电池模组6出现松散甚至解体的情况。优选地，压紧部34可以设置有多个，且由于电池模组6的形状通常为方形，可选地，围框支撑台31为方环状结构，相应地，压紧部34可以设置有四个，四个压紧部34可以分别设置在围框支撑台31的四个角部，以进一步提升对电池模组6的压紧效果。
进一步地，模组测高机构3中还可以设置有限位块35，限位块35的具体结构可以根据实际需求确定，限位块35可以安装在围框支撑台31上，限位块35用于与电池模组6限位配合，以防止在对电池模组6测量的过程中，电池模组6的位置发生变化。优选地，限位块35可以设置多个，多个限位块35围绕中间缺口311设置，以全面限制电池模组6的位置。可选地，限位块35可以采用可调连接的方式与围框支撑台31连接，从而可以根据电池模组6的实际尺寸对应调整限位块35的固定位置。
进一步地，涂胶设备中还设置有活动架4，涂胶机构2可以通过活动架4安装在机架1上，在这种情况下，涂胶机构2在工作过程中可以在活动架4的作用下移动，这使得涂胶机构2上仅需设置一个出胶口即可。在涂胶过程中，当向目标区域的涂胶工作结束之后，在活动架4的作用下，涂胶机构2能向下一目标运动，这可以简化涂胶设备的整体结构复杂程度。可选地，机架1上还可以设置有用于定位待涂胶部件的机构，且该机构可以设置于涂胶机构2的下方，从而降低涂胶工作的进行难度，且便于胶水快速凝固成型。
为了进一步提升涂胶设备的自动化程度，如图3所示，本申请所提供的涂胶设备还可以包括上料机械手5，上料机械手5可以包括夹具51和活动部52，二者相互连接，夹具51用于夹取电池模组6和底板7，在电池模组6的组装过程中，上料机械手5可以先将底板7转运至用于定位待涂胶部件的机构处，然后，涂胶机构2在胶量控制机构的控制下完成对该待涂胶部件的涂胶工作，最后，上料机械手5再夹取缺少底板7的电池模组6，并将其与底板7固定连接在一起，完成电池模组6的组装工作。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于 本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
