电池具有能量密度高、可循环充电、安全环保等优点，因此被广泛应用于新能源汽车、消费电子、储能系统等领域中。现有技术中的电池采用的贴膜工艺，由聚对苯二甲酸乙二醇酯(Polyethylene terephthalate， PET)为膜基材，将压敏胶涂布在膜基材上形成贴膜，贴覆在电池外壳起到绝缘作用。使用这种贴膜工艺的贴膜机械强度低，耐穿刺能力差，易磨损失效，同时电池外壳与膜层之间粘接强度低，无法满足强震动工况和长寿命使用要求。
为了解决这个问题，需要在电池外壳上其他涂层，对于其他涂层而言，往往需要不同的方法实现电池表面的涂布，其中淋涂是常用的手段之一。现有的淋涂装置通常只是对被淋涂物体的顶部进行淋涂，并使涂料逐渐扩散至被淋涂物体的侧面，以实现涂料的整体覆盖，但是这种淋涂方式容易出现局部淋涂过度，而侧面淋涂不足的现象。

可选地，第一淋涂机构2与第二淋涂机构3内的淋涂材料为双组分丙烯酸聚合物体系，与传统水性漆体系相比，本申请实施例中的淋涂材料在成膜后具有绝缘性能优越，机械性能良好等优点，适用于例如电池单体等对涂层性能要求较高的待淋涂件1。
本申请实施例中的第一淋涂机构2和第二淋涂机构3分别对待淋涂件1的第一面11和外周面12进行淋涂处理，从而保证淋涂材料在第一面11和外周面12上的淋涂均一性，进而可以确保待淋涂件1的第一面11和外周面12上的绝缘层分布均匀可靠。
如图1和图2所示，在一些实施例中，外周面12包括多对相对设置的侧面121，第二淋涂机构3包括多个淋涂组件31，多个淋涂组件31分别用于淋涂多对侧面121。
在本申请实施例中，待淋涂件1的结构可以为六面体、八面体等形状，而外周面12包括多对相对设置的侧面121是指，外周面12包括有多对相互平行的两个侧面121，且相互平行的两个侧面121在水平方向上相对设置。
第二淋涂机构3包括多个淋涂组件31，多个淋涂组件31分别对应于多对侧面121，以在多对侧面121上淋涂绝缘层，即每对侧面121至少对应有一个淋涂组件31，每个淋涂组件31至少用于对待淋涂件1的一 个侧面121进行淋涂处理。其中，多个淋涂组件31可以同时淋涂，也可以在不同时段分别进行淋涂，本申请实施例对此不作限制。
本申请实施例中多个淋涂组件31分别用于淋涂多对侧面121，以确保待淋涂件1的每对侧面121均淋涂有绝缘层，从而提高待淋涂件1外表面的可靠性。
在一些实施例中，至少一对侧面121中的每一个侧面121均对应设置有淋涂组件31。
每对侧面121均包括两个相对设置的侧面121，其中至少一对侧面121中的两个侧面121均对应设置有淋涂组件31，以使淋涂组件31能够同时相对设置的两个侧面121同时淋涂。示例性地，所有侧面121均对应设置有淋涂组件31，且淋涂组件31的淋涂口沿水平方向指向对应的侧面121。
本申请实施例中至少一对侧面121中的每一个侧面121均对应设置有淋涂组件31，这种设计可以在淋涂时同时对相对设置的两个侧面121同时淋涂，提高淋涂效率。
如图1和图2所示，在一些实施例中，至少一个侧面121对应设置有多个淋涂组件31。
可以理解的是，单个淋涂组件31的可淋涂范围由淋涂组件31的结构尺寸等因素决定，因此对于面积较大的侧面121而言，单个淋涂组件31可能无法保证整个侧面121淋涂完全。因此本申请实施例将至少一个侧面121对应设置有多个淋涂组件31，以使多个淋涂组件31对一个侧面121进行淋涂，保证单个侧面121的各个区域可以形成结构均一的绝缘层，进一步增强淋涂装置的淋涂可靠性。
在一些实施例中，请参阅图3，淋涂装置还包括传送机构4，用于沿传送方向传送多个待淋涂件1；其中，多个淋涂组件31在传送方向上间隔设置，多个淋涂组件31分别与多个待淋涂件1对应设置。

示例性地，传送机构4为传送带结构，通过电动滚筒实现传动运行，多个待淋涂件1设置在传送带上，并由电动滚筒驱动移动至对应有淋涂组件31的位置处，然后由淋涂组件31对其进行淋涂形成绝缘层，最后由电动滚筒驱动并带动淋涂完成后的成品离开淋涂装置。
在一些实施例中，请参阅图1和图3，淋涂装置还包括旋转机构5，用于带动待淋涂件1转动，以使第二淋涂机构3对待淋涂件1的外周面12的不同区域淋涂。
旋转机构5直接或间接连接于待淋涂件1，并用于带动待淋涂件1转动，以使一个淋涂组件31的淋涂口能够指向待淋涂件1外周面12的不同区域，进而确保一个淋涂组件31能够对待淋涂件1的外周面12的不同区域进行淋涂处理。可选地，旋转机构5为旋转气缸或驱动电机。
需要说明的是，传送机构4与旋转机构5可以配合使用。具体地说，传送机构4能够带动多个待淋涂件1移动至多个淋涂组件31位置处，淋涂组件31负责淋涂待淋涂件1的特定区域，然后旋转机构5带动待淋涂件1旋转，以使待淋涂件1的外周面12的不同区域朝向淋涂组件31，淋涂组件31对外周面12的不同区域进行淋涂，然后重复此操作直至待淋涂件1的外周面12的所有区域淋涂完成，最后传送机构4带动淋涂完成后的设备移动离开淋涂装置。
本申请实施例利用旋转机构5带动待淋涂件1转动，使得一个淋涂组件31的淋涂口能够指向待淋涂件1外周面12的不同区域，即一个淋涂组件31能够对待淋涂件1的外周面12的不同区域进行淋涂，从而能够减小第二淋涂机构3中淋涂组件31的数量，降低制造成本。
在一些实施例中，请参阅图4和图5，淋涂装置还包括回收槽6， 回收槽6位于待淋涂件1在竖直方向的下方。
第一淋涂机构2和第二淋涂机构3在淋涂过程中，部分淋涂材料会从待淋涂件1向下滴落，导致淋涂材料的浪费。因此为了减小浪费，本申请实施例在待淋涂件1的正下方设置了回收槽6，用于对滴落的淋涂材料进行回收利用。进一步地，回收槽6还对淋涂材料的集中回收，有利于淋涂材料的后续加工使用。此外回收槽6的设置还可以起到防止淋涂材料滴落至传送机构4和旋转机构5上的作用，保证传送机构4和旋转机构5能够长久运行。回收槽6的形状与尺寸根据实际使用情况决定，本申请实施例对此不作限定。

在一些可选实施例中，淋涂装置还包括排液管道63和设置于排液管道63上的控制阀，排液管道63设置于容纳罐62和回收槽6上，淋涂完成后，多余的淋涂材料通过排液管道63从容纳罐62和回收槽6中排出，控制阀用于控制容纳罐62和回收槽6与排液管道63之间的导通或断开。可以理解的是，本申请实施例中还可以包括有过滤器、液位计、流量计等等，本申请实施例对此不作限定。

本申请实施例通过在承载面71上设置有定位槽72，实现待淋涂件1在承载台7上的定位，以防淋涂过程中时，待淋涂件1受力离开承载台7，保证淋涂装置整体结构的可靠性。
在一些实施例中，淋涂装置还包括吸气机构8，承载台7包括与吸气机构8连通的气体通道73，气体通道73包括设置于承载面71的导气孔74，吸气机构8通过导气孔74将待淋涂件1吸附于承载面71。
吸气机构8能够气体抽离并在局部空间内形成真空，示例性地，吸气机构8包括真空泵，真空泵与气体通道73连通，气体通道73的一端与导气孔74相连。使用时，首先将待淋涂件1通过定位槽72放置在承载台7上，然后真空泵运行将气体通道73内的空气吸走，在压强作用的影响 下，待淋涂件1与承载台7的承载面71之间贴合吸附，实现两者相互固定。
