本发明一种锂电池隔膜高效双面涂覆装置，工作原理如下：
系统工作时隔膜基材1沿隔膜基材运行方向运行经过安装于滑动板9上的2组导向辊A2，在2组导向辊A2间由顺时针转动的正面涂布辊3将封闭涂布液供给装置4中的涂布液转移涂覆至隔膜基材1正面完成正面涂覆后经过导向辊A2并沿隔膜基材运行方向运行至驱动辊5，顺时针转动的驱动辊5输送隔膜基材1经过导向辊B8后由顺时针转动的反面涂布辊7将涂布液定量供给装置6供给的涂布液转移涂覆至隔膜基材1反面，至此完成隔膜基材1正反面双面涂覆；涂布液供给系统供给的涂布液通过供给管道从胶腔两侧进入胶腔，通过胶腔特有的结构在胶腔中分散开供给给正面涂布辊3，多余部分的胶液从胶腔中间回胶口返回供胶系统。涂布液通过图2的A-A截面处管道进入反面涂布辊7，多余的涂布液流入涂布定量供给装置两侧，通过B-B截面处排出口留回供胶系统中。通过气缸35粗调滑板9上两导向辊与正面涂布辊之间的相对距离，再通过滑动板9上小螺距的螺杆29精密调整其之间距离，这样实现了正面涂覆过程中隔膜基材与正面涂布辊包角的调节。隔膜基材运行速度一般为2～40m/min，正面涂布辊与反面涂布辊的切线速度一般为隔膜基材运行速度的1.5倍左右，以上实际速度受具体工艺影响。
系统工作时可根据实际工艺通过调节正面涂布辊3转速及封闭涂布液供给装置4涂布液供给量来调整隔膜基材1正面涂覆量；通过调节反面涂布辊7转速及涂布液定量供给装置6涂布液供给量来调整隔膜基材1反面涂覆量；通过调节驱动辊5转速实现设备速度的调整；同时可以通过滑动板位置调节装置11的调节使滑动板9沿滑轨10前后移动调节隔膜基材1与正面涂布辊3的相对距离，实现正面涂覆过程中隔膜基材1与正面涂布辊3包角的调节。
