本发明为中国发明专利名称为“一种锂电池极片材料通用的区域底涂装置”，申请号：202010112386.0，申请日：2020.2.24的分案申请。
技术领域
本发明涉及底涂装置领域，具体为一种锂电池极片材料通用的区域底涂装置。
背景技术
聚合物锂离子电池是目前使用非常普遍的电池，目前聚合物锂离子电池的研究和生产都取得了重大的进展，在各个领域的应用也越来越广泛。近年来聚合物锂离子电池是手机等移动电子装置的首选电池。随着聚合物锂离子电池的广泛运用，需求聚合物锂离子电池的领域也越来越多，这就要求生产越来越多的聚合物锂离子电池满足使用需求。锂离子电池制造工艺中，涂布是核心的工序，也是决定电池性能的主要工艺步骤。
现有的一种锂电池极片材料通用的区域底涂装置的缺陷：
1、印版辊整根进行刻纹涂覆，当基膜部分区域不需要涂覆时，无法实现。
2.当印版辊采用分段刻纹时，只能适应一种宽度的涂覆或者不用涂覆的区域，无法通用，满足不了不同宽度和不同区域涂布的要求。
发明内容
本发明的目的在于提供一种锂电池极片材料通用的区域底涂装置，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：一种锂电池极片材料通用的区域底涂装置，包括过辊、印版辊、刮刀和浆料箱，所述浆料箱的内部装有浆料，所述浆料箱的顶部安装有印版辊，所述印版辊两侧浆料箱的顶部安装有刮刀，所述印版辊顶部的两侧安装有塑料薄膜支撑，所述塑料薄膜支撑的顶部安装有过辊，所述过辊与塑料薄膜支撑之间放置有塑料薄膜，所述塑料薄膜的顶部放置有基材。
进一步，所述浆料箱的底部设置有防滑层。
进一步，所述印版辊的表面设置有雕刻区域。
进一步，所述基材通过印版辊后留下涂覆区域。
进一步，所述一侧塑料薄膜支撑的顶部设置有积墨区。
与现有技术相比，本发明的有益效果是：
1、本发明采用塑料薄膜材料实现涂覆区域的隔离，简单快捷；
2、本发明塑料薄膜成本低，实现区域涂布的效益高；
3、本发明通过控制塑料薄膜宽度和数量，即可实现不同宽度和不同区域的涂覆要求。
附图说明
图1为本发明的通用区域涂布方式结构图；
图2为本发明的基材区域涂布原理图。
图中：1、过辊；2、基材；3、积墨区；4、印版辊；5、刮刀；6、浆料箱；7、浆料；8、塑料薄；9、塑料薄膜支撑；10、涂覆区域；11、雕刻区域。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。在本发明的描述中，需要说明的是，术语“上”、“下”、“内”、“外”“前端”、“后端”、“两端”、“一端”、“另一端”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性。在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“设置有”、“连接”等，应做广义理解，例如“连接”，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
请参阅图1-2，本发明提供的一种实施例：一种锂电池极片材料通用的区域底涂装置，包括过辊1、印版辊4、刮刀5和浆料箱6，浆料箱6的内部装有浆料7，浆料箱6的顶部安装有印版辊4，印版辊4两侧浆料箱6的顶部安装有刮刀5，去除涂布过程中多余的浆料7，印版辊4顶部的两侧安装有塑料薄膜支撑9，塑料薄膜支撑9的顶部安装有过辊1，支撑和控制基材2贴合在印版辊4上，过辊1与塑料薄膜支撑9之间放置有塑料薄膜8，隔离印版辊4的刻纹区域，塑料薄膜8的顶部放置有基材2。
进一步，浆料箱6的底部设置有防滑层。
进一步，印版辊4的表面设置有雕刻区域11。
进一步，基材2通过印版辊4后留下涂覆区域10。
进一步，一侧塑料薄膜支撑9的顶部设置有积墨区3，浆料7聚集的区域。
工作原理：基材2在前进过程中，被过辊1向下托住，从而使基材2贴合在印版辊4的圆柱面上，当印版辊4运转时，带动浆料7通过积墨区3涂覆在基材2的表面。其中浆料箱6用来存储浆料7，刮刀5用来去掉多余的浆料7，在涂布开始前，先将印版辊4用塑料薄膜8贴合在非涂覆区域，因此，印版辊4的雕刻区域11被塑料薄膜8遮挡，无法将浆料7带入基材2的表面，从而实现分区域涂布。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
