本装置的使用方法及工作原理:在使用该锂电池极片高精控厚均涂装置时,首先,启动第二电缸711,第二电缸711的活动杆向下伸长,并推动滑板714,滑板714沿着两根光滑杆713向下滑动,使得滑板714带动控厚组件73和双侧均涂组件72向下移动至烘干槽装置2的内腔,位于与纠偏装置3两侧的纠偏轮齐平位置;接着,将电极卷搭在纠偏装置3上,并穿过双侧均涂组件72的中间区域,使电极卷上下各分布两组涂布辊724,打开输入管54并关闭螺旋输出管55,第一电缸51的启动,其活动杆收缩,带动活塞块53在涂料罐52内壁向上移动,使得涂料罐52内部产生负压,从输入管54抽取涂料进入涂料罐52,此时关闭输入管54并打开螺旋输出管55,第一电缸51的活动杆慢速向下按压活塞块53,涂料从涂料罐52底部孔和双层架57中部孔进入螺旋输出管55中,经过连接阀715进入分支钢管721中;进入到分支钢管721中的涂料分别进入若干韧性软管722中,接着分别注入对应的涂布辊724的端部环形槽725中,而长柱槽726的内径略大于细辊728的外径,两者之间存在一定间隙,若干分料槽727与环形槽725连通,涂料从环形槽725进入分料槽727和间隙中,使得每个细辊728外侧环绕涂料;然后,第三电缸741的活动杆向下伸长,推动连轴件743在内置板737的中部槽中向下滑动,滑动的过程中带动两个连板742运动,两个连板742之间的夹角逐渐变大,两者之间的水平距离变大,分别推动两端的单齿轮件738,两个单齿轮件738受到向外的力,在弧形槽740内壁以及两个弧形卡条739组成的限位环中向外作扇形圆周运动,单齿轮件738连接的双侧均涂组件72水平高度上升,在与第二齿轮件735连接的双侧均涂组件72配合下,上下两组双侧均涂组件72分别贴合在电极卷上下两侧;接着,启动马达731,马达731带动第一双齿轮件732在外壳体733的内部上端转动,第一双齿轮件732的两齿轮在两个第一皮带734的传动下,分别带动第二齿轮件735转动,从而分别带动第二皮带736转动,使得对应的单齿轮件738旋转,两个第二齿轮件735和两个单齿轮件738带动对应连接的涂布辊724转动;上下两组涂布辊724分别贴合在电极卷上下两侧滚动,同时横移装置4带动均涂机构7水平移动,若干细辊728接触到电极卷后产生摩擦力,该摩擦力使得细辊728在长柱槽726内腔中滚动,接触时细辊728向内收缩产生缝隙,环绕在细辊728外侧的涂料从缝隙中渗出,滚动的过程中涂料涂覆在电极卷的两侧,多个细辊728独立滚动放料,提高涂覆的均匀程度,烘干槽装置2工作,对涂覆的区域进行烘干,而韧性软管722的是韧性材料,两端分别在分支钢管721分支管和侧环723中转动,避免涂布辊724滚动时,扭转打结;一层涂覆结束后,第三电缸741的活动杆收缩一定距离,增大上下两组涂布辊724之间的垂直高度差,横移装置4带动均涂机构7往回移动,同样原理进行二次涂覆,重复几次上述操作即实现多次涂覆,对涂层厚度进行精准控制,该段距离的电机卷涂覆结束后,拉动电机卷在纠偏装置3上移动,进行新区域的涂覆。
