Description

说 明 书 间歇涂布装置和应用涂布装置的压力涂布机及涂布方法 技术领域
本发明涉及涂布机械领域， 尤其是一种正反面涂布都能保证精度的 间歇涂布装置和应用涂布装置的压力涂布机及涂布方法。 背景技术
涂布是锂离子电池生产过程中必不可少的工序， 也是直接影响电池 安全性、 容量、 一致性等各项性能的关键工序。 涂布就是将制作好的糊 状粘稠浆料， 均匀的、 连续或间断的涂覆在基体（铝箔或铜箔） 的正、 反两面上， 保证各个涂布位置的厚度一致性、 并将涂布厚度控制在工艺 要求的公差范围内。
国内外的挤压涂布技术日趋成熟， 涂布精度越来越高。 目前的挤压 涂布方式， 参照附图 1、 附图 2和附图 3 , 涂布头 1缝口中心正对涂布 辊 5中心面， 在涂布头 1对基体 4进行挤压涂布实现间歇涂布时， 面临 一个影响涂布厚度一致性的技术瓶颈。 基体 4的两面设为 A面和 B面， 参照附图 1 , 锂离子电池间歇涂布工艺要求在涂覆基体 4A面时， 须留有 一定的间歇位。 在涂覆基体 4B面时， 当基体 4A面间歇位经过涂布头 1 时，由于间歇位比正常涂覆位薄一个涂覆厚度，基体会在张力作用下 "塌 陷"， 造成基体与涂布头缝口的间隙突然变大。 如果 A、 B面间歇位对齐 或反面间歇位比正面间歇位长， "塌陷" 区域不需要涂布（如图 2 ), 则 该 "塌陷" 现象不会影响涂布厚度； 当正、 反面间歇位错位， 须在 "塌 陷" 区域涂布时， 则会导致 "塌陷" 区域的涂布厚度偏厚（如图 3 )。 因 此， 目前挤压涂布机对于该种锂电间歇涂布工艺的适应性， 仍然是一片 空白。
另外， 由于涂布头缝口中心正对涂布钢辊中心面， 涂布头缝口与涂 布钢辊之间的间隙非常小， 大约 30-100 μ ηι, 经常因为浆料颗粒、 基体 褶皱导致基体被刮断； 同时， 误操作或控制失灵， 会造成涂布头撞击涂 布钢辊， 导致二者损伤或 ^艮废。 发明内容
本发明的目的是提供一种在保证精度的情况下解决正反面间歇涂 布的间歇涂布装置和应用涂布装置的压力涂布机及涂布方法。
为解决上述技术问题， 本发明提供一种间歇涂布装置， 所述涂布装 置包括涂布头、 传动辊 A与传动辊 B , 传动辊 A的轴线与传动辊 B的轴 线平行排列， 基体一侧卷绕通过传动辊 A和传动辊 B上， 涂布头设置在 基体的另一侧， 朝向所述传动辊 A与传动辊 B之间的所述基体。
作为本发明的改进， 完成对涂布过程的 调， 所述传动辊 A或传动 辊 B为可移动的传动辊,移动方向沿着传动辊 A或传动辊 B的径向方向。
作为本发明的改进， 更好的控制微调数量， 所述可移动的传动辊上 设置有控制传动辊微量调节的手动调节支座。
作为本发明的改进， 所述传动辊 A的轴线与传动辊 B轴线确定的平 面与水平面垂直。
为解决上述技术问题， 本发明还提供一种压力涂布机， 包括间歇涂 布装置， 所述涂布装置包括涂布头、 传动辊 A与传动辊 B , 传动辊 A的 轴线与传动辊 B的轴线平行排列， 基体一侧卷绕通过传动辊 A和传动辊 B上， 涂布头设置在基体的另一侧， 朝向所述传动辊 A与传动辊 B之间 的所述基体， 所述传动辊 A的轴线与传动辊 B轴线确定的平面与水平面 垂直。
作为本发明的改进， 所述传动辊 A或传动辊 B为可移动的传动辊， 移动方向沿着传动辊 A或传动辊 B的径向方向上。
作为本发明的改进， 所述可移动的传动辊上设置有控制传动辊微量 调节的手动调节支座。
本发明还提供一种压力涂布方法， 包括步骤二次涂布： 将基体跨于 两根传动辊上传动， 并在两根传动辊之间对基体进行二次涂布， 所述基 体背向二次涂布面的一面为经过一次涂布的涂布面。
作为本发明的改进， 在二次涂布步骤之前， 进行一次涂布， 所述一 次涂布为： 将基体跨于两根传动辊上传动， 并在两根传动辊之间对基体 进行一次间歇涂布。 作为本发明的改进， 传动辊可以沿着传动辊径向方向上移动， 调节 基体的位置。
本发明的有益效果是： 涂布时， 涂布头缝口的浆料直接涂覆在悬空 的基体上。 由于涂布头缝口中心不再正对涂布辊中心面， 基体不需要反 面涂布辊作为承载体， 因此在涂覆基体反面时， 当基体正面间歇位经过 涂布头时， 由于基体由两端传动辊支撑， 正面间歇位处于悬空状态， 基 体不会形成 "塌陷"， 基体与涂布头缝口的间隙不变。 当正面涂布间歇 位通过其中一传动辊时， 因为间歇位比正常涂覆位薄一个涂覆厚度， 基 体会在张力作用下以另一传动辊为轴心做远离涂布头缝口的摆动偏移， 但是， 涂覆厚度仅 50-300 μ ηι, 而传动辊离涂布头缝口的距离约 150mm, 通过三角函数关系比较， 基体摆动角度极小， 因此基体相对于涂布头缝 口的偏移也非常小， 对涂布厚度精度的影响在工艺控制范围内。
当有异物、 浆料颗粒或基体打皱通过涂布头缝口， 基体会克服张力 相对于涂布头缝口往后移， "容纳" 异物、 浆料颗粒或褶皱凸起通过， 只会影响该段的涂布质量， 不会造成刮裂， 不会因此原因断带。
因为误操作或控制失灵， 造成涂布头行程过量时， 涂布头会沖击基 体， 不会与钢辊接触， 基体会克服张力随着涂布头缝口后移， 不会对涂 布头造成损伤。 附图说明

参照附图 4和附图 5 , 附图所示为本发明提供的一种压力涂布机， 包括间歇涂布装置， 所述涂布装置包括涂布头 1、 传动辊 A2 与传动辊 B3 , 传动辊 A2的轴线与传动辊 B3的轴线平行排列， 基体 4一侧卷绕通 过传动辊 A2和传动辊 B3上， 涂布头 1设置在基体 4的另一侧， 朝向所 述传动辊 A2与传动辊 B3之间的所述基体 4。
本发明的压力涂布方法， 包括步骤二次涂布： 将基体 4跨于两根传 动辊上传动， 并在两根传动辊之间对基体 4进行二次涂布， 所述基体 4 背向二次涂布面的一面为经过一次涂布的涂布面。
参照附图 4 , 附图所示为在二次涂布步骤之前， 进行一次涂布， 所 述一次涂布为： 将基体 4跨于两根传动辊上传动， 并在两根传动辊之间 对基体进行一次间歇涂布。
所述一次涂布也可为： 用涂布头 1缝口中心正对涂布辊 5中心面， 对通过涂布辊 5的基体进行间歇涂布。
具体如下： 首先采用上述任意一种一次涂布方法对基体 4一面进行 间歇涂布， 被涂布的面设为 A面， 涂布后的基体 4在经过本发明的压力 涂布机， 如图 5 , 附图采用两条加工精度比较高的传动辊， 两个传动辊 的轴线平行排列， 一次涂布后的基体 4跨于两根传动辊上传动， A面朝 向传动辊， 背对 A面的一面设为 B面， 将涂布头 1缝口中心正对两传动 辊之间的基体 B面， 涂布时， 涂布头 1缝口的浆料直接涂覆在悬空的基 体 B面上。 由于涂布头 1缝口中心不再正对涂布辊 5中心面， 基体 4不 需要处在基体反面涂布辊 5作为承载体， 所以在涂布基体 B面时， 当基 体 A面间歇经过涂布头 1时， 由于基体由两端的传动辊支撑， A面间歇 处于悬空状态， 基体 4不会形成 "塌陷"， 基体 4与涂布头 1缝口的间 隙不变。 当 A面间歇位通过其中一个传动辊时， 因为间歇位比正常涂覆 位薄一个涂覆厚度， 基体 4会在张力的作用下以另一条传动辊为轴心做 远离涂布头 1缝口的摆动偏移。
但是， 涂覆的厚度仅 50-300 μ ηι, 而两传动辊之间的距离为 150mm 左右， 通过三角函数的关系比较， 基体 4摆动角度极小， 因此基体 4相 对于涂布头 1缝口的偏移也非常小， 对涂布厚度精度影响在工艺控制范 围内。
当有异物、 浆料颗粒或基体 4打皱通过涂布头 1缝口， 由于基体 4 一般为弯曲软体材质，基体 4会克服张力相对于涂布头 1缝口后移， "容 纳" 异物、 浆料颗粒或褶皱凸起通过， 只会影响该段的涂布质量， 不会 造成刮裂， 不会因此原因断带。
因为误操作或控制失灵， 造成涂布头 1行程过量时， 涂布头 1会沖 击基体 4 , 基体 4会克服片路张力随着涂布头 1缝口后移， 不会对涂布 头 1造成损伤。
参照附图 4和附图 5 , 附图所示为本发明的另一实施例中， 所述传 动辊 A或传动辊 B为可移动的传动辊， 移动方向沿着传动辊 A或传动辊 B的径向方向。
传动辊 A或传动辊 B沿着径向方向的移动可以防止微量形变导致左 右张力不均的基体 4涂布， 进而也可以赋予所述基体 4张力， 使基体 4 更好的涂布， 达到均匀。
参照附图 4和附图 5 , 附图所示为本发明的另一实施例中， 所述可 移动的传动辊上设置有控制传动辊微量调节的手动调节支座 6。
可用机器代替手动， 更精确的对具体情况进行分析， 和在适合的时 候进行微调。
本发明的另一实施例中， 参照附图 4和附图 5 , 附图所示所述传动 辊 A的轴线与传动辊 B轴线确定的平面与水平面垂直。
垂直方向上可以使涂覆的浆料更均匀。
以上所述仅为本发明的实施例， 并非因此限制本发明的专利范围， 凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换， 或 直接或间接运用在其他相关的技术领域， 均同理包括在本发明的专利保 护范围内。
