背景技术
电池极片在涂布的过程中，需要将其放入烘箱进行烘干。为保证烘干效果及生产效率，烘箱长度通常较长，且烘箱内设置多个导辊，因此使得涂布过程中极片位于烘箱中的部分较多，导致极片在烘箱内部断带的几率增大。
而当极片在烘箱内部断带，由于烘箱长度较长，只能打开烘箱侧门并人工将断裂的极片拉出烘箱进行连接。在此过程中，由于极片部分被拉出烘箱，将导致施力方向偏离极片在烘箱内的移动方向，导致极片错位甚至二次断带。此外，人工从侧面进行连接的方式也不利于提高生产效率。
发明内容

目前，从市场形势的发展来看，动力电池的应用越加广泛。动力电池不仅被应用于水力、火力、风力和太阳能电站等储能电源系统，而且还被广泛应用于电动自行车、电动摩托车、电动汽车等电动交通工具，以及军事装备和航空航天等多个领域。随着动力电池应用领域的不断扩大，其市场的需求量也在不断地扩增。
动力电池的生产工艺流程中包括涂布工序，在涂布工序中，涂布完成的电池极片需放入烘箱中进行烘干，以便于进行下一步加工处理。然而目前为了确保烘干效果及生产效率， 常常将烘箱设置较长的长度，以使极片得到充足的干燥。正因如此，极片在烘箱内移动的过程中，容易导致极片受力不均而发生断带。
针对上述极片断带的问题，若无辅助装置的情况下，常规的做法多是由操作人员停止加热烘箱，待烘箱内温度下降至合适温度后，工作人员穿戴好劳保用品，打开烘箱侧门，从侧面手动在烘箱内拉扯极片穿过烘箱。极片拉出烘箱后与另一断裂边连接，通过缓慢走带将此部分收卷。在此期间，存在耗时大的问题。具体的，烘箱需要足够的时间进行降温以及重启后升温。此外，人工手动将极片拉出烘箱时，容易导致施力方向偏离极片在烘箱内的移动方向，从而导致极片错位甚至引起二次断带。此外，由于烘箱内空间狭小，人工手动将极片拉出烘箱时不便于操作且耗时费力。
因此，目前在烘箱内部设置有穿带辅助结构，例如设置导轨及位于导轨内的移动件，使移动件带动极片沿导轨走带。而某些烘箱内部空间并非完全平直，而是具有一定弧度。针对这类弧度烘箱，现有技术常采用链条带动极片在烘箱内移动。并且链条在烘箱内的安装方式有两种，其中之一是采用链条配合导轨，使链条在导轨内移动从而带动极片移动。这种方式的安装要求较高，若安装不到位则会导致弧度烘箱内出现卡死，不利于实际使用。其中之另一则是使用链轮支撑链条，这种方式中，由于链条自重较大容易造成脱轨，从而导致极片断带，并且安装复杂。
基于上述情况，申请人研究发现，可以通过牵引绳对极片进行牵引，带动极片在弧度烘箱内移动。由于牵引绳的自重较小，在移动过程中不容易脱轨，从而能够更稳定的带动极片移动。此外，牵引绳的柔韧性更好，在烘箱内部的安装更加灵活方便，且能够带动极片在复杂环境中顺利走带。
基于以上考虑，为了解决穿带装置带动极片在弧度烘箱内走带时容易脱轨或卡顿，导致生产效率低下且容易导致极片断带的问题，申请人经过深入研究，设计了一种穿带装置及烘烤设备，采用牵引绳带动极片移动，使极片的走带更加顺利。
参阅图1及图2，图1为本申请一实施例中穿带装置的结构示意图，图2为本申请一实施例中穿带装置的局部结构示意图。本实用新型一实施例提供了一种穿带装置100，用于运输极片，穿带装置100包括主体(图中未示出)、引带机构10以及驱动机构20。其中，主体具有用于容纳极片的运输空间，且引带机构10设置于运输空间内。此外，引带机构10包括牵引绳11，牵引绳11沿极片的运输方向延伸，且与极片相连以带动极片移动。驱动机构20与牵引绳11驱动连接，以驱动牵引绳11带动极片沿运输方向移动。
需要说明的是，牵引绳11可以采用钢丝绳，钢丝绳具有良好的刚度，能够减小在走带过程种断裂的风险，因此能够对极片起到稳定支撑的作用。此外，由于钢丝绳在移动摩擦的过程中，容易产生金属微粒，而金属微粒在烘箱内部的高温环境中，容易粘黏至极片上而导致污染极片。因此，可以在钢丝绳外包覆一层非金属防护层，该非金属防护层不仅能够对 钢丝绳起到一定的保护作用，还能够避免钢丝绳在移动过程中产生金属微粒污染极片，从而能够确保极片质量。
可以理解地，在一些其他实施例中，牵引绳11也可以采用除钢丝绳之外的其他类似绳体结构，或者直接采用由非金属材料制作而成的绳体结构，在此不作赘述。
具体到本实施例中，由于穿带装置100用于在烘箱内对极片进行穿带，因此，穿带装置100设置于烘箱内部，即运输空间位于烘箱内部。牵引绳11与极片固定连接，在驱动机构20的驱动下，牵引绳11可带动极片沿特定的路径移动。牵引绳11具有良好的柔韧性，因此能够更平滑地带动极片在烘箱内按照特定路径移动，避免移动过程中的脱轨或卡顿问题，使极片走带更加顺利且稳固。
此外，牵引绳11与极片采用间接连接的方式进行固定，即可借助连接件将极片固定至牵引绳11上，由此实现极片与牵引绳11的稳定连接。
如图2所示，穿带装置100包括沿重力方向设于牵引绳11下侧的托轮30，托轮30上开设有沿运输空间延伸的引导槽31，牵引绳11设置于引导槽31中。
具体地，引导槽31沿托轮30的周向设置，且引导槽31设置为中间凹陷的形状。托轮30通过其轮轴固定至烘箱的内侧壁上，且能够绕轮轴转动。当牵引绳11容置于引导槽31内时，托轮30一方面对牵引绳11起到支撑作用，防止牵引绳11因其自身重力而下垂。此外，中间凹陷的引导槽31能够防止位于其中的牵引绳11脱出，确保牵引绳11在引导槽31内移动的稳定性。
进一步地，在实际应用中，托轮30固定于烘箱的内侧壁上，并且沿运输方向设置多个。全部托轮30上的引导槽31共同形成不连续的引导路径，使钢丝绳能够带动极片沿该引导路径移动。此外，引导槽31能够对钢丝绳进行限位，避免钢丝绳脱离托轮30，从而能够减少极片断带的风险。
在一些实施例中，托轮30包括第一子托轮和第二子托轮，其中，第一子托轮和第二子托轮在与运输方向相交的水平面内间隔布置。牵引绳11包括第一子绳体111与第二子绳体112,第一子绳体111与第二子绳体112分别设置于第一子托轮和第二子托轮的引导槽31内，且两者之间形成用于容纳极片的穿带空间113。引带机构10包括连接组件12，连接组件12的两端分别与第一子绳体111及第二子绳体112相连，以将极片固定于穿带空间113内。
具体到本实施例中，第一子托轮和第二子托轮沿极片的宽度方向分别对应设置于极片的两侧，并且在极片宽度方向上的两侧分别设置第一子绳体111与第二子绳体112。其中，极片两侧的第一子托轮和第二子托轮分别固定于烘箱内相对的两个内侧壁上，从而相对设置，以便于第一子绳体111与第二子绳体112能够分别容置于第一子托轮和第二子托轮的引导槽31内。
进一步地，第一子托轮和第二子托轮沿极片的运输方向设置多组，且每一组中的第一 子托轮和第二子托轮相互对应设置。因此，牵引绳11能够沿多组第一子托轮和第二子托轮的设置路径延伸，从而带动极片在该路径上移动。
第一子绳体111与第二子绳体112之间形成穿带空间113，极片位于该穿带空间113内。此外，连接组件12即为穿带杆，穿带杆的两端分别与第一子绳体111及第二子绳体112固定连接，并且穿带杆与极片固定。由此，当第一子绳体111与第二子绳体112在驱动机构20的驱动下在引导槽31内移动时，穿带杆能够带动极片同步移动。
在一些实施例中，连接组件12包括连接本体121及设于连接本体121上的至少一个固定部122，固定部122用于固定第一子绳体111和/或第二子绳体112，以连接连接组件12与牵引绳11。
具体到本实施例中，固定部122设置有两个，且分别设置于连接本体121的两端。连接本体121即为穿带杆的杆本体，位于杆本体两端的固定部122用于固定第一子绳体111及第二子绳体112。
进一步地，杆本体的两端可通过固定部122与第一子绳体111及第二子绳体112固定连接，即直接将第一子绳体111及第二子绳体112穿设于固定部122中，如图2所示，以实现两者的固定连接，该方法使连接更加稳定。
此外，固定部122两端进行倒角设置，使固定部122形成一梯形结构，以便于固定部122从托轮30和与其对应的压轮40之间通过，避免固定部122经过托轮30与压轮40之间时造成卡顿。
请参看图3，图3为本申请另一个实施例中穿带装置的局部结构示意图。在一些实施例中，固定部122被构造为夹持件，用于夹持第一子绳体111和/或第二子绳体112。具体地，夹持件包括两个间隔设置的板状配件，两个板状配件之间形成一固定位，并且两个板状配件能够沿彼此靠近或者彼此远离的方向运动，从而改变固定位的大小。固定位可用于容纳牵引绳11，对牵引绳11进行夹持时，将牵引绳11放置于固定位内，并使两个板状配件朝向彼此靠近的方向运动，直至将牵引绳11夹持固定。当不需要对牵引绳11进行夹持时，只需使两个板状配件朝向彼此远离的方向运动，使两者之间的固定位增大，从而使牵引绳11从两者之间脱出即可。
极片在烘箱内走带过程中，夹持件能够分别将第一子绳体111及第二子绳体112夹持固定，以实现极片与穿带杆的连接，从而带动极片移动。而当极片停止走带或需要进行其他操作时，夹持件可放开第一子绳体111及第二绳体112，实现两者的分离，从而更加灵活方便。
请再次参看图2，在一些实施例中，穿带装置100包括压轮40，压轮40与托轮30对应设置，且两者之间界定形成一限位空间，牵引绳11设置于限位空间内。
具体地，压轮40通过其轮轴固定至烘箱的内侧壁上，且能够绕其轮轴转动。此外，压轮40沿重力方向设置于托轮30上方，且压轮40与托轮30一一对应设置。每一组对应的 压轮40与托轮30之间沿重力方向均形成限位空间，第一子绳体111及第二子绳体112可限位于该限位空间内。
当第一子绳体111及第二子绳体112在对应托轮30的引导槽31内移动时，第一子绳体111及第二子绳体112可能会沿极片的宽度方向脱离引导槽31，从而导致脱轨，而第一子绳体111及第二子绳体112的脱轨将导致极片在走带过程中受力不均匀，从而引起断带。
设置压轮40后，压轮40对第一子绳体111及第二子绳体112产生向下的压力，能够将第一子绳体111及第二子绳体112沿重力方向限位于对应的引导槽31内，避免第一子绳体111及第二子绳体112脱离引导槽31。
在一些实施例中，穿带装置100包括浮动机构50，浮动机构50包括固定件51与弹性件52。其中，固定件51与主体固定连接。弹性件52的一端连接于固定件51，另一端连接于压轮40，以改变压轮40与托轮30之间的间距。
作为一种具体的实施例，弹性件52可采用弹簧，弹簧连接于固定件51与压轮40之间，可调整压轮40与托轮30之间的间距。可以理解地，弹性件52也可以采用与弹簧类似的其他结构，在此不作赘述。
具体地，固定件51固定设置于烘箱的内壁上，弹性件52连接于固定件51与压轮40之间。由此，当第一子绳体111及第二子绳体112位于限位空间内时，由于安装误差无法避免，第一子绳体111与第二子绳体112在移动过程中会产生上下浮动。而弹性件52能够根据第一子绳体111及第二子绳体112上下浮动的幅度，调整压轮40与托轮30之间的间距，使第一子绳体111及第二子绳体112能够更顺利地通过限位空间。
请参看图4及图5，图4为本申请一实施例中穿带装置的结构示意图，图5为本申请一实施例中连接组件的结构示意图。为了使连接组件12与极片的固定更加稳固，连接组件12包括间隔设置的第一子部123与第二子部124，第一子部123与第二子部124之间形成用于夹持极片的夹持位125。
具体地，穿带杆的杆本体被分为第一子部123与第二子部124，第一子部123与第二子部124沿重力方向间隔设置。由此，第一子部123与第二子部124之间可形成夹持位125，并将极片夹持于该夹持位125中，使极片与穿带杆之间的连接更加稳定。
在一些实施例中，连接组件12包括连接于第一子部123与第二子部124之间的调节件126，调节件126用于调节第一子部123与第二子部124在重力方向上的间距。
具体到本实施例中，调节件126为设置于第一子部123与第二子部124之间的调节螺栓。通过调节螺栓，能够改变第一子部123与第二子部124之间在重力方向上的距离，从而使第一子部123与第二子部124之间的夹持位125能够适应不同厚度的极片，避免第一子部123与第二子部124对极片的夹持过紧而导致损坏极片，或者过松而导致极片脱离。
因此，通过控制调节件126，能够根据极片的实际厚度调节夹持位125的尺寸，使极 片能够更稳固地夹持于夹持位125中，从而确保极片走带的稳定性。
请再次参看图1，在一些实施例中，驱动机构20包括驱动连接的驱动轮21和驱动源(图中未示出)，牵引绳11沿运输方向首尾相连地绕设于驱动轮21上，以在驱动源的驱动下沿运输方向移动。
具体地，驱动轮21设置于烘箱的首尾两端，且沿极片的宽度方向设置两组。第一子绳体111及第二子绳体112分别沿极片的运输方向首尾相连地绕设于烘箱首尾两端的驱动轮21上，驱动轮21能够在驱动源的驱动下转动，从而带动第一子绳体111及第二子绳体112沿极片的运输方向移动，由此，可实现极片的走带。
由于烘箱内部可利用的空间较少，因此通常将驱动轮21设置于烘箱外，且位于烘箱首尾两端的入口处及出口处，并带动第一子绳体111及第二子绳体112移动。
基于与上述实施例中的穿带装置100相同的构思，本申请提供一种烘烤设备，用于干燥极片，烘烤设备包括烘箱及如上所述的穿带装置100。其中，烘箱具有用于干燥极片的容纳空间，穿带装置100设置于容纳空间内。
本申请具体使用时，驱动轮21在驱动源的驱动下转动，带动第一子绳体111与第二子绳体112沿极片的运输方向移动。在烘箱内部，第一子绳体111及第二子绳体112沿对应托轮30的引导槽31移动，并且位于第一子绳体111及第二子绳体112上方的压轮40能够防止第一子绳体111与第二子绳体112脱离引导槽31。
当穿带杆经过托轮30与压轮40之间时，托轮30与压轮40可从固定部122上滚过，与此同时，弹簧调节托轮30与压轮40在重力方向上的间距，从而使穿带杆顺利通过限位空间。
上述实施例中的穿带装置100及烘烤设备，至少具有以下优点：
(1)第一子绳体111及第二子绳体112具有良好的柔韧性，能够带动极片在弧度烘箱内部复杂的环境中顺利走带，降低穿带装置100卡顿或脱轨的风险，避免极片断带；
(2)托轮30能够对第一子绳体111及第二子绳体112起到支撑作用，防止第一子绳体111及第二子绳体112因自身重力而下坠，从而减小第一子绳体111与第二子绳体112的受力；
(3)托轮30上的引导槽31能够沿极片的宽度方向对第一子绳体111及第二子绳体112进行限位，避免第一子绳体111与第二子绳体112在移动过程中脱离引导槽31而造成极片断带；
(4)夹持件通过夹持的方式实现穿带杆与第一子绳体111及第二子绳体112的连接，使连接方式更加灵活，便于拆装；
(5)压轮40能够对第一子绳体111及第二子绳体112产生向下的压力，沿重力方向将第一子绳体111与第二子绳体112限位于引导槽31内，使第一子绳体111与第二子绳体112 在引导槽31内的移动更加顺畅；
(6)弹簧能够灵活调整托轮30与压轮40之间的间距，以便于固定部122能够顺利通过两者之间的限位空间，使极片走带更加顺利；
(7)第一子部123与第二子部124之间形成夹持位125，能够根据极片的实际厚度对极片进行更灵活的固定，并且使极片能够更稳定的与穿带杆连接，避免极片在走带过程中与穿带杆脱离。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围，其均应涵盖在本申请的权利要求和说明书的范围当中。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本申请并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
