请参阅图1及图2，本申请提供了一种用于电芯与上盖组装的设备10，该用于电芯与上盖组装的设备10包括焊接装置100及第一搬运装置200。
焊接装置100包括驱动机构110及焊接载具120，焊接载具120为至少两个，且每个焊接载具120均能够承载合芯组件20。驱动机构110可以采用传动链、电机螺纹丝杠副与滑块配合的结构、旋转盘等结构。在驱动机构110的驱动下，至少两个焊接载具120能够交替进入焊接工位101，承载于焊接载具120的合芯组件20能够在焊接工位101完成焊接。
驱动机构110能够驱动每个焊接载具120在焊接工位101与上下料工位102之间移动。具体在本实施例中，驱动机构110可设置至少两个彼此独立的驱动端，从而能够带动每个焊接载具120独立进行移动。如此，能够避免至多个焊接载具120的工作过程产生相互干扰。显然，在其他实施例中，至少两个焊接载具120也可在驱动机构110的驱动下同步移动。
在本实施例中，两个上下料工位102设于焊接工位101的相对两侧，焊接载具120为两个，两个焊接载具120在驱动机构110的带动下能够分别在两个上下料工位102与焊接工位101之间移动。
如此，两个焊接载具120能够在工作过程中彼此独立、互不干扰。如图2所示，当左侧的焊接载具120移动至焊接工位101时，右侧的焊接载具120移动至右侧的上下料工位102，故在对左侧的焊接载具120内的合芯组件20进行焊接时，可对右侧的焊接载具120进行合芯组件20的上料及下料。当左侧的焊接载具120内的合芯组件20焊接完后，可移动至左侧的上下料工位102以将焊接好的合芯组件20下料并将待焊接的合芯组件20上料至左侧的焊接载具120内；而右侧的焊接载具120则进入焊接工位101，以使右侧的焊接载具 120内的合芯组件20完成焊接。
第一搬运装置200包括上料机构210及下料机构220，当焊接载具120移动至上下料工位102时，上料机构210能够将待焊接的合芯组件20放置于焊接载具120，而下料机构220能够将焊接完成的合芯组件20从焊接载具120取出。
上料机构210及下料机构220的结构相同，可采用吸盘、夹爪等形式，只要能够抓取合芯组件20即可。具体在本实施例中，第一搬运装置200还包括第一传动机构230。第一传动机构230可采用传动链等形式，上料机构210及下料机构220设置于第一传动机构230独立的两个驱动端。第一传动机构230能够带动上料机构210及下料机构220沿图2所示的左右方向移动，从而能够使上料机构210及下料机构220将抓取的合芯组件120转移至所需的位置。
需要指出的是，在其他实施例中，上料机构210及下料机构220也可分别集成多轴机械手等能够实现位置转移的机构，故上料机构210及下料机构220也可实现独立的运动。此时，第一传动机构230可省略。
当其中一个焊接载具120进入焊接工位101并进行合芯组件20的焊接时，其他的焊接载具120可在驱动机构110的带动下移动至上下料工位102。此时，下料机构220便可将焊接完成的合芯组件20从焊接载具120取出，并由上料机构210将待焊接的合芯组件20放置于焊接载具120。如此循环，至少两个焊接载具120交替进入焊接工位101，从而实现合芯组件20的连续焊接。而且，在对一个合芯组件20进行焊接的过程中，可对其他合芯组件20进行下料及上料，从而能够利用对焊接的时间进行合理利用，进而有利于提升生产效率。
在本实施例中，用于电芯与上盖组装的设备10还包括下料装置800，下 料装置800包括下料载具810及传送机构820，下料机构220能够将焊接完成的合芯组件20从焊接载具120转移至下料载具810，传送机构820能够将下料载具810传送至指定位置。
传送机构820可以是输送皮带、传动链等结构，在传送机构820的驱动下，下料载具810可先移动至能够承接合芯组件20的位置，待下料机构220将焊接完成的合芯组件20放置于下料载具810之后，传送机构820便可带动下料载具810及其内的合芯组件20移动至设备外部或下一工序。下料载具810内的合芯组件20被取走后，将在传送机构820的带动下再次回到能够承接合芯组件20的位置，并依次循环。
在本实施例中，每个焊接载具120均能够承载多个合芯组件20，焊接工位101的相对两侧分别设置有多个焊接机构130，每一侧的多个焊接机构130能够同时对焊接载具120内的多个合芯组件20进行焊接。多个焊接机构130同时对多个合芯组件20进行焊接，能够进一步提升生产效率。
如图5及图6所示，合芯组件20包括两个电芯21及上盖22，每个电芯21与上盖22之间形成两个焊接点位共四个焊接点位。
以图2所示为例，每个焊接载具120上均能够承载两个合芯组件20，焊接工位101的两侧分别设置有三个焊接机构130，且按照从右向右的方向分别对焊接机构130及焊接载具120上的两个合芯组件20进行编号。当焊接载具120位于1号及2号焊接机构130的相对侧时，1号焊接机构130及2号焊接机构130分别焊接1号合芯组件20的右焊接点位以及2号合芯组件20的左焊接点位；焊接完后，焊接载具120移动预设距离，并移至2号焊接机构130及3号焊接机构130的相对侧。此时，2号焊接机构130及3号焊接机构130 便可分别焊接1号合芯组件20的左焊接点位以及2号合芯组件20的右焊接点位，从而完成焊接载具120上两个合芯组件20的焊接。
需要指出的是，在其他实施例中，还可将焊接机构130的数量设置成与焊接载具120内的合芯组件20的数量一致。而且，每个焊接机构130能够同时对左右两个焊接点位进行焊接。
为了提升于电芯与上盖组装的设备10的自动化的程度，请再次参阅图1，在本实施例中，用于电芯与上盖组装的设备10还包括上盖供料装置300、电芯供料装置400、第二搬运装置500及合芯中转装置600。
上盖供料装置300及电芯供料装置400能够分别提供上盖22及电芯21，第二搬运装置500包括上盖抓取组件510及电芯抓取组件520，合芯中转装置600包括合芯载具610，上盖抓取组件510及电芯抓取组件520能够分别抓取上盖供料装置300及电芯供料装置400提供的上盖22及电芯21并放置于合芯载具610，以组装得到合芯组件20。具体的，可在合芯载具610上先放一个电芯21，再放上盖22，最后放一个电芯21，便可得到一个合芯组件20。
进一步的，合芯中转装置600能够驱动合芯载具610移动至所承载的合芯组件20能够被上料机构210抓取的位置。合芯载具610可以先移动至能够承接电芯21及上盖22的位置，待顺利接收盖抓取组件510及电芯抓取组件520抓取的电芯21及上盖22并完成合芯组件20的制备后，合芯载具610便移动至上料机构210能够抓取合芯组件20的位置。因此，针对合芯载具610的上料及下料是在不同的位置进行的，故能够有效地避免执行上述两个操作的元件产生相互干扰。
此外，合芯载具610还能够实现翻转，如旋转90度。在电芯21以上盖 22配对时，合芯载具610使配对的两个电芯21与上盖22处于水平状态以方便对准；合芯组件20组装完成后，合芯载具610则翻转90度以使合芯组件20处于竖直状态。如此，能够方便上料机构210夹取合芯组件20，从而保证将合芯组件20顺利上料至焊接载具120。
可见，电芯与上盖组装的设备10能够实现合芯组件20的实时制备，并将制备好的合芯组件20上料至焊接载具120上完成焊接。
进一步的，用于电芯与上盖组装的设备10一般还包括底板900，焊接装置100、第一搬运装置200、上盖供料装置300、电芯供料装置400、第二搬运装置500及合芯中转装置600均安装于底板900。而且，为了避免上盖22及电芯21的供料过程相互干扰，上盖供料装置300及电芯供料装置400分别设置于底板900相对的两端，即图1所示的左右两端。而合芯载具610则设置于上盖供料装置300与电芯供料装置400之间。
上盖抓取组件510及电芯抓取组件520的结构可以相同，也可采用吸盘、夹爪等形式。第二搬运装置500还包括第二传动机构530，第二传动机构530也可采用传动链等形式，上盖抓取组件510及电芯抓取组件520分别设置于第二传动机构530相互独立的两个驱动端。第二传动机构530能够驱动上盖抓取组件510及电芯抓取组件520沿底板900的长度方向，即图1所示的左右方向移动。因此，在第二传动机构530的驱动下，上盖抓取组件510及电芯抓取组件520能够顺利将抓取的上盖22及电芯21转移至合芯载具610上。
需要指出的是，在其他实施例中，上盖抓取组件510及电芯抓取组件520也可分别集成多轴机械手等能够实现位置转移的机构，故上盖抓取组件510及电芯抓取组件520也可实现独立的运动。此时，第二传动机构530可省略。
具体在本实施例中，上盖抓取组件510能够抓取多个上盖22，电芯抓取组件520能够抓取多个电芯21，以在合芯载具610上组装得到至少两个合芯组件20。可见，至少两个合芯组件20同时制备，并同时被上料至焊接载具120以进行焊接，故能够进一步提升生产效率。
具体的，上盖抓取组件510设有两个夹爪气缸，两个夹爪气缸能够同时动作以同时夹取两个上盖22。而电芯抓取组件520设有四个夹爪气缸，四个夹爪气缸能够同时动作以同时夹取四上盖电芯21。因此，在合芯载具610上能够同时组装得到两个合芯组件20。
在本实施例中，用于电芯与上盖组装的设备10还包括上盖检测装置700。其中，上盖检测装置700包括第一输送机构710、第一载具720及检测机构730。
第一输送机构710可以采用传动链、电机螺纹丝杠副与滑块配合的结构等。上盖供料装置300能够将上盖22输送至第一载具720，第一载具720在第一输送机构710的驱动下能够带动上盖22经过检测机构730的检测范围。具体的，检测机构730可以是CCD相机、扫描仪等。检测机构730能够对经过检测范围的上盖22进行检测，以判断上盖22是否合格。
经过检测机构730的检测后，第一输送机构710继续带动第一载具720移动至能够被上盖抓取组件510抓取的位置。若第一载具720上的上盖22被判断为合格，上盖抓取组件510则抓取上盖22并将其转移至合芯载具610上以进行合芯组件20的组装；若第一载具720上的上盖22被判断为不合格，上盖抓取组件510则将所抓取的上盖22转移至废料放置区，以将不合格的上盖22剔除。
请一并参阅图3及图4，在本实施例中，上盖供料装置300包括托盘输入 机构310、托盘输出机构320、托盘转移机构330、第二输送机构340及上盖取料机构350。
具体的，上盖22放置于托盘内，且每个托盘内可放置多个上盖22。托盘输入机构310、托盘输出机构320的结构一般相同，仅传送方向相反。托盘输入机构310及托盘输出机构320均可采用输送皮带、传动链等形式，主要能够带动托盘进给即可。托盘输入机构310能够将装有上盖22的托盘输送至能够被托盘转移机构330抓取的位置，托盘转移机构330便可抓取装有上盖22的托盘。
托盘转移机构330一般包括传动件及抓取件，传动件能够驱动抓取件移动。抓取件抓取托盘后，传动件能够将抓取的托盘朝第二输送机构340移动。其中，第二输送机构340包括第二输送组件341及第二载具342，托盘转移机构330能够将抓取的托盘转移至位于托盘入料位置的第二载具342。在第二输送组件341的带动下，第二载具342能够带动托盘在托盘入料位置与上盖取料位置之间移动。第二载具342在托盘入料位置承接装满上盖22的托盘后，便在第二输送组件341的驱动下移动至上盖取料位置。
上盖取料机构350可采用带夹爪或吸盘的机械手，能够将位于上盖取料位置的托盘内的上盖22转移至第一载具720，以实现对上盖22的检测。当托盘内的上盖22被取完后，第二输送组件341便带动第二载具342回到托盘入料位置。进一步的，托盘转移机构330还能够将位于托盘入料位置的托盘转移至托盘输出机构320。
上盖供料装置300的工作过程大致如下：
装满上盖22的托盘可由满托盘物料线30输送至托盘输入机构310，托盘 输入机构310依次将装满上盖22的托盘移动至托盘转移机构330的下方；接着，托盘转移机构330抓取单个托盘并依次转移至第二载具342内；第二载具342承接到装满上盖22的托盘后，第二输送组件341动作并带动第二载具342移动至上盖取料位置；上盖取料机构350便可将托盘内的上盖22依次转移至第一载具720以进行检测，直至托盘内的上盖22被取完。待一个托盘内的上盖22全部被取完后，第二输送组件341将带动第二载具342及其上空置的托盘回到托盘入料位置；托盘转移机构330动作，将空置的托盘搬运至托盘输出机构320；最后，托盘输出机构320动作，将空置的托盘转移至空托盘物料线40，从而便可将空置的托盘移出以供再次利用。重复上述动作，装满上盖22的托盘将不断被转移至上盖取料位置，以供盖取料机构350取用上盖22，而空置的托盘则不断被运出。
进一步的，在本实施例中，第二载具342设置有至少两个，且至少两个第二载具342在第二输送组件341的带动下能够交替在托盘入料位置与上盖取料位置之间移动。
具体的，当其中一个第二载具342上托盘内的上盖22被取完后，该第二载具342可在第二输送组件341的带动下由上盖取料位置移动至托盘入料位置，从而使空置的托盘回到托盘入料位置；与此同时，另一个承载有装满上盖22的托盘的第二载具342则可在第二输送组件341的带动下进入上盖取料位置，以供盖取料机构350取用上盖22。如此，盖取料机构350等待的时间将显著缩短甚至可实现连续取料，从而能够进一步提升生产效率。
请再次参阅图1，在本实施例中，电芯供料装置400包括电芯输送机构410、电芯转移机构420及定位机构430。
电芯输送机构410可采用输送皮带的形式，电芯21可依次排列于输送皮带的表面并进行运输。由于合芯组件20中电芯21的数量是上盖22数量的两倍，故为了匹配上盖22的数量，本实施例中的电芯输送机构410设置有两组，两组电芯输送机构410能够同步运行，并将电芯21输送至能够被电芯转移机构420抓取的位置。
电芯转移机构420同样包括传动件及抓取件，传动件可以是传动链等结构，抓取件可采用夹爪、吸盘等。具体在本实施例中，抓取件也设置有两组，以分别用于抓取两组电芯输送机构410上的电芯21，传动件则驱动抓取电芯21的抓取件朝定位机构430移动。
定位机构430包括传动组件431及定位件432；电芯转移机构420能够将抓取的电芯21转移至位于电芯入料位置的定位件432，定位件432能够对所承载的电芯21进行定位。在传动组件431的驱动下，定位件432能够带动电芯21在电芯入料位置与能够被电芯抓取组件520抓取的位置之间移动。具体的，定位件432能够先移动至电芯入料位置，以使电芯转移机构420能够将抓取的电芯21放置于定位件432内；待定位件432完成对电芯21的定位后，传动组件431驱动定位件432移动至能够被电芯抓取组件520抓取的位置。此时，电芯抓取组件520便能够将电芯21从定位件432转移至合芯载具610，并与上盖22配对组装成合芯组件20。
而且，经过定位件432可对电芯21的位置实现纠偏，还有利于提升合芯组件20的配对精度。
上述用于电芯与上盖组装的设备10，当驱动机构110带动其中一个焊接载具120进入焊接工位101时，承载于该焊接载具120的合芯组件20便可在 焊接工位101内完成焊接。同时，其他的焊接载具120则可在驱动机构110的带动下移动至上下料工位102，从而由下料机构220将焊接完成的合芯组件20从焊接载具120取出，并由上料机构210将待焊接的合芯组件20放置于焊接载具120。由此可见，在对一个合芯组件20进行焊接的过程中，可对其他合芯组件20进行下料及上料，从而能够利用对焊接的时间进行合理利用。因此，上述用于电芯与上盖组装的设备10能够提升锂电池的生产效率。
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。
