图2为图1所示的检测装置的右视结构示意图。
具体实施方式
为使本申请的上述目的、特征和优点能够更加明显易懂，下面结合附图对本申请的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本申请。但是本申请能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本申请内涵的情况下做类似改进，因此本申请不受下面公开的具体实施例的限制。
在本申请的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本申请的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
在本申请中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。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申请中的具体含义。
在本申请中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
需要说明的是，当元件被称为“固定于”或“设置于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“垂直的”、“水平的”、“上”、“下”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
如图1及图2所示，本申请一实施例提供的检测装置100，包括安装架11、充气机构20以及检测机构30。
充气机构20和检测机构30均设置于安装架11，充气机构20可往工件的焊缝充入第一气体。
检测机构30包括检测头31及第一检测件，检测头31用于与工件的焊缝连通，第一检测件与检测头31连通，用于检测第一气体。
本实施例中，工件为电池，第一气体为氦气，而工件的焊缝为电池注液口处的焊缝，具体为电池中铝钉焊接时的焊缝。当然，在其他实施例中，工件也可以是其他的产品，对应第一气体也可以是其他的气体，只要第一气体不影响产品即可。
通过设置上述的检测装置，在电池的铝钉焊接之后，充气机构20往焊缝充入第一气体，而后将工件移动至检测机构30处，检测头31与焊缝连通，然后通过第一检测件检测焊缝是否存在第一气体。如果检测到第一气体，说明焊接的密封性不合格，而如果没有检测到第一气体，说明焊接的密封性合格。如此，该检测装置能够检测焊接的密封性，从而确保电池的质量。
需要解释的是，工件为电池时，如果焊接的密封性合格，充气机构20往焊缝充入第一气体后，由于第一气体无法穿过焊缝，在将工件移动至检测机构30的过程中第一气体会消散，因此第一检测件无法检测到第一气体。而如果焊接的密封性不合格，第一气体能够通过焊缝渗透进入铝钉和胶钉之间，在将工件移动至检测机构30的过程中，第一气体无法完全消散，从而使得第一检测件能够检测到第一气体。
在一些实施例中，检测装置还包括底板12及驱动机构13，安装架11及驱动机构13均设置于底板12，驱动机构13用于驱动工件沿第一方向移动，以使 工件经过充气位置和检测位置。
当工件位于充气位置时，充气机构20可往工件的焊缝充入第一气体；当工件位于检测位置时，检测头31可与工件的焊缝连通，从而通过第一检测件检测是否存在第一气体。
第一方向为图1中的左右方向，且为图2中垂直纸面的方向。结合图1进行说明，驱动机构13驱动电池从右至左移动，电池先移动到充气位置，充气机构20向电池注液口的焊缝充入第一气体，而后驱动机构13继续驱动电池朝左移动，直至电池移动到检测位置，接下来由检测头31与电池注液口处的焊缝连通，并通过第一检测件检测是否存在第一气体，从而判断铝钉焊接的密封性。
实际应用中，驱动机构13为电缸。
在一些实施例中，检测装置还包括定位机构40，驱动机构13与定位机构40传动连接，以驱动定位机构40沿第一方向移动，定位机构40用于承载并定位工件。也就是说，电池通过定位机构40承载并定位后，由驱动机构13驱动定位机构40沿第一方向移动，使得电池依次经过充气位置和检测位置。
在一些实施例中，定位机构40包括承载板41、第一定位组件及第二定位组件，承载板41沿第一方向可往复移动地设置于底板12，驱动机构13与承载板41传动连接，承载板41用于承载工件，第一定位组件和第二定位组件均设置于承载板41，第一定位组件用于沿第一方向定位工件，第二定位组件用于沿与第一方向垂直的第二方向定位工件。
其中，第二方向为图1中垂直纸面的方向，且为图2中的左右方向。
在一些实施例中，第一定位组件包括第一固定块42、第一定位块43及第一定位驱动件44，第一固定块42固定连接于承载板41，第一定位驱动件44设置于承载板41，且与第一定位块43传动连接，用于驱动第一定位块43沿第一方向往复移动，以使第一定位块43靠近和远离第一固定块42。
在一些实施例中，第二定位组件包括第二固定块45、第二定位块46及第二定位驱动件47，第二固定块45固定连接于承载板41，第二定位驱动件47设置于承载板41，且与第二定位块46传动连接，用于驱动第二定位块46沿第二方向往复移动，以使第二定位块46靠近和远离第二固定块45。
需要说明的是，本实施例中，电池沿第一方向纵长布设，第一定位块43靠近第一固定块42的过程中，第一定位块43和第一固定块42可分别抵接于电池沿第一方向的相对两端，第二定位块46靠近第二固定块45的过程中，第二定位块46和第二固定块45可分别抵接于电池沿第二方向的相对两侧，从而在第一方向和第二方向上对电池进行定位。
在一些实施例中，定位机构40包括至少两组第一定位组件及至少两组第二定位组件，每组第一定位组件和对应的一组第二定位组件用于对一工件进行定位，从而将至少两个工件定位于承载板41上。
可以确定的是，承载板41上承载至少两个工件时，充气机构20能够同时对至少两个工件的焊缝进行充气，而检测机构30包括至少两个检测头31，以分别对至少两个工件的焊缝进行检测，提高检测效率。
另外，如图2所示，图2中定位两个电池，两个电池沿第二方向间隔排布，而两组第二定位组件共用一个第二固定块45。因此，条件允许的情况下，相邻的两组第一定位组件可以共用一个第一固定块42，相邻的两组第二定位组件可以共用一个第二固定块45。
在一些实施例中，第一定位驱动件44和第二定位驱动件47均为气缸。
在一些实施例中，定位机构40还包括第二检测件，第二检测件设置于承载板41，用于检测经过第一定位组件和第二定位组件定位的工件的表面缺陷。
本实施例中，工件为电池，第二检测件用于检测电池是否发生鼓包以及电池是否发生破损，如存在鼓包或破损，可直接将电池判定为不合格。
实际应用中，第二检测件为位移传感器。
在一些实施例中，充气机构20包括充气头21及第一充气组件，充气头21设置于安装架11，用于与工件的焊缝连通，第一充气组件与充气头21连通，用于往工件的焊缝充入第一气体。
由此可知，工件移动到充气位置时，充气头21可与工件的焊缝连通，然后由第一充气组件往工件的焊缝充入第一气体。
可以确定的是，工件为电池时，充气头21和检测头31均可完全覆盖电池的注液口，且充气头21和检测头31内设有密封圈，以与电池密封接触，从而 确保检测精度。
进一步地，充气机构20还包括第二充气组件及第三检测件22，第二充气组件与充气头21连通，用于往工件的焊缝充入第二气体，第三检测件22设置于充气头21或第二充气组件，用于检测充气头21内的压力。
需要说明的是，工件移动到充气位置时，充气头21与工件的焊缝连通，先通过第二充气组件往焊缝充入第二气体，直到充气头21内的压力达到预设压力，然后由第三检测件22检测充气头21内的压力。如果压力无法保持或者预设时间内无法达到预设压力，则说明焊接的密封性不合格，如果预设时间内能够达到预设压力并保持，则说明没有明显泄漏问题。
在第二充气组件和第三检测件22检测合格后，将带有压力的气体排出，然后通过第一充气组件往工件的焊缝充入第一气体，接下来再将工件移动到检测位置，通过检测机构30检测第一气体。
假设第二充气组件和第三检测件22配合对焊接密封性的检测为第一次检测，而第一充气组件与检测机构30配合对焊接密封性的检测为第二次检测，可以理解的是，第二次检测的精度高于第一次检测的精度，但是检测成本也更高，因此第一次检测可提前剔除焊接密封性明显不合格的工件，从而无需进行第二次检测，降低成本。
此外，本实施例中，第二气体为压缩气体，而第三检测件22为压力检测器，由于第二充气组件与充气头21连通，故压力检测器设置于第二充气组件时，也能够检测充气头21内的压力。
在一些实施例中，充气机构20还包括充气驱动件23，充气驱动件23设置于安装架11，且与充气头21传动连接，以驱动充气头21沿与第一方向垂直的第三方向往复移动，充气头21移动供的过程中可抵接于位于充气位置的工件，以与工件的焊缝连通。
第三方向为图1和图2中的上下方向，在工件移动到充气位置时，充气驱动件23驱动充气头21下降，直至充气头21抵接于工件并与工件的焊缝连通。
实际应用中，充气驱动件23为气缸。
在一些实施例中，充气机构20还包括排气阀，排气阀与充气头21连通， 用于连通充气头21与外界，从而将充气头21内的高压气体排出。
在一些实施例中，检测机构30还包括抽气件，抽气件连接于检测头31与第一检测件之间，用于抽取气体至第一检测件，以使第一检测件检测是否存在第一气体。
实际应用中，抽气件为真空泵，第一检测件为氦检仪。
在一些实施例中，检测机构30还包括检测驱动件32，检测驱动件32设置于安装架11，且与检测头31传动连接，以驱动检测头31沿第三方向往复移动，检测头31移动的过程中可抵接于位于检测位置的工件，以与工件的焊缝连通。
工件移动到检测位置时，工件位于检测头31的下方，检测驱动件32驱动检测头31下降，直至与工件相抵接，检测头31与工件的焊缝连通，然后抽气件将气体抽取至第一检测件，第一检测件检测是否存在第一气体。
实际应用中，检测驱动件32为气缸。
为了便于理解本申请的技术方案，在此以电池为例，结合图1对上述实施例中的检测装置的检测流程进行说明：
电池放置于承载板41上，第一定位组件和第二定位组件对电池进行定位，定位之后通过第二检测件检测电池的表面是否存在鼓包或破损，检测合格后驱动机构13驱动承载板41朝左移动。
电池随承载板41移动到充气位置后，充气驱动件23驱动充气头21下降并抵接于电池的注液口处，然后第二充气组件通过充气头21往电池注液口处的焊缝充入压缩气体，配合第三检测件22检测充气头21内的压力是否达到预设压力，并检测是否能够保持在预设压力。
检测到压力能够达到并保持在预设压力后，排气阀打开，将高压气体排出，排出后关闭排气阀，并且由第一充气组件通过高压往焊缝充入氦气，充入氦气后保压一段时间，然后充气驱动件23驱动充气头21上升，并且驱动机构13再驱动承载板41朝左移动。
电池随承载板41移动到检测位置后，检测驱动件32驱动检测头31下降并抵接于电池的注液口处，然后抽气件抽取气体至第一检测件，第一检测件检测气体中是否存在氦气。
需要解释的是，充气位置和检测位置之间的间距较小，而且如果电池中铝钉的焊接合格，第一检测件检测不到氦气；如果电池中铝钉的焊接不合格，则在高压充入氦气的过程中，氦气会进入铝钉和胶钉之间的缝隙，使得电池从充气位置移动到检测位置的过程中，氦气无法消散，从而使得第一检测件能够检测到氦气。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
