Title of Invention:电池极片圆压圆模切装置 技术领域
技术领域
[1] 本实用新型涉及电池制造领域, 尤其涉及电池极片的模切装置。
背景技术
背景技术
[2] 目前, 公知的电池极片模切都是以平压平的方式冲切出来的。 制作电池的单张 成型极片吋, 将卷状极片材料, 经送料装置、 纠偏装置送入极片模切装置, 分 切成单张成型极片。 用该方式模切电池极片吋, 极片材料需在模切区停留一段 吋间, 待模切完毕后又开始送料。 因为这种平压平模切是一种间歇式工作方式 , 不能连续送料和模切, 因此工作效率比较低。 而且在平压平模切极片吋, 模 切刀的工作刃口同吋参与模切工作, 需要很大的压力才能将材料切透分离, 而 模切刀在受力太大吋易变形和受损, 因此该种模切方式目前还不能模切大尺寸 的极片, 其应用受到限制。 另外还有一种模切方式是圆压圆模切装置, 这种装 置可连续工作, 现在主要用于纸质材料或塑胶材料的模切, 但圆压圆模切装置 无法应用于硬质材料的模切。 因电池极片釆用金属材料, 与纸质材料或塑胶材 料有着显著区别, 技术上也要求更严格, 技术上要求: 无论是极耳位, 还是涂 布层, 模切后不能有没切断的现象, 哪怕是一点点没切断都不行, 即不能有拉 断的现象; 无论是负极片还是正极片, 模切后的毛刺不得大于 0.01mm, 即不能 大于极片的厚度的一半; 模切后的极耳位与涂布层不能有起折的现象; 模切后 极片的尺寸要一致, 大小不能相差 0.3mm。 所以目前还没有釆用圆压圆模切装置 来对电池极片进行加工。 发明人在釆用圆压圆模切装置模切电池极片吋遇到以 下问题:
[3] A、 负极片铜箔的厚度一般为 0.01mm左右, 而负极片的涂布层的厚度一般为 0.
15mm左右, 二者相差很大, 导致涂层很好切, 而极耳位切不断, 模切后容易出 现毛刺, 并且有些不能完全切断, 模切后的极耳位与涂布层有起折的现象, 模 切后极片的尺寸难以做到一致。
[4] B、 模切刀的圆角相交处的刀刃容易崩齿。
对发明的公开
技术问题
[5] 本实用新型要解决的主要技术问题是, 提供一种电池极片圆压圆模切装置, 使 电池极片加工可釆用圆压圆模切方式。
技术解决方案
[6] 为解决上述技术问题, 本发明提供一种电池极片圆压圆模切装置, 包括:
[7] 互相平行设置的模辊和刀模辊, 所述模辊和刀模辊之间保留适当的间隙, 所述 刀模辊的表面设有用于切割极片的刀模线, 所述模辊和刀模辊之间设有垫层, 且使电池极片位于所述垫层和刀模线之间, 所述垫层的硬度小于电池极片的硬 度;
[8] 驱动系统, 其动力输出端耦合到所述模辊和刀模辊, 用于驱动模辊和刀模辊同 步相对转动。
[9] 在另一实施例中, 所述刀模线刀口的底部还设有泡棉, 所述泡棉的高度大于刀 模线的高度。
[10] 在又一实施例中, 所述刀模辊上具有多个单元的刀模线, 所述相邻单元的相邻 刀模线之间具有间距。
有益效果
[11] 1、 本实用新型通过在刀模辊和模辊增加一个垫层, 既不会损坏切刀, 又能切 断极片, 通过选择垫层的硬度, 还可以解决不能完全切断与有毛刺的问题。
[12] 2、 本实用新型通过在刀模线刀口的底部加了一层一定厚度的泡棉, 使极片在 移动吋速度均匀, 避免了极片移动速度不均匀造成的极片起折与尺寸不一致的 问题。
[13] 3、 本实用新型将相邻刀模线间隔设计, 消除极片相交处的内应力, 防止极片 相交处的刀刃出现崩齿。

本发明的实施方式
[22] 下面通过具体实施方式结合附图对本实用新型作进一步详细说明。
[23] 本实用新型釆用可连续送料和模切的装置来模切电池极片, 以提高工作效率。
[24] 在一种实施例中, 将现有的圆压圆模切装置经过改进用于模切电池极片, 改进 的模切装置如图 1、 2所示, 包括平行设置的刀模辊 1和模辊 2, 用于驱动模辊 2和 刀模辊 1同步相对转动的驱动系统 (图中未示出) 。 刀模辊 1的表面设有刀模线 1 1, 刀模线 11凸起在刀模辊 1的表面。 在刀模辊 1和模辊 2之间设置设有垫层 3, 所 述垫层 3的硬度小于电池极片的硬度, 在工作吋, 使电池极片位于所述垫层 3和 刀模线 1之间。
[25] 工作吋, 极片从刀模辊 1和垫层 3之间穿过并被刀模辊 1和垫层 3压紧, 刀模辊 1 和模辊 2在驱动装置的带动下, 二者相向滚动, 极片与刀模辊、 垫层二者之间产 生滚动摩擦力, 该摩擦力使得极片沿相应的方向运动, 与此同吋极片被刀模辊 上的刀模线切割。 刀模线的形状可根据切割后极片的形状、 尺寸要求进行设计 。 因为电池极片有的地方有涂层, 有的地方没有涂层, 因此厚度不均匀, 硬度 也不均匀, 负极片铜箔的厚度一般为 0.01mm左右, 而负极片的涂布层的厚度一 般为 0.15mm左右, 二者相差很大, 导致涂层很好切, 而极耳位切不断。 为解决 此问题, 本实施例在刀模辊 1和模辊 2之间设有一硬度小于电池极片的硬度的垫 层 3。 刀模线 11在模切电池极片吋, 由于垫层 3的硬度较小, 在刀模辊的压力下 会稍有下陷, 在电池极片厚度大的地方, 垫层下陷深些, 在电池极片厚度小的 地方, 垫层下陷浅些, 通过垫层的缓冲, 使电池极片的厚度在模切效果上是均 匀的, 从而使刀模线能够将不容易切断的极耳位切断。 [26] 为更好地切断电池极片, 垫层的厚度优选设为 0.115mm-0.135mm。
[27] 针对不能完全切断与有毛刺的现象, 选用的垫层可以是有一定硬度、 厚度均匀 的垫纸, 例如可釆用厚度均匀的 PET材料的垫纸。
[28] 在另一种实施例中, 圆压圆模切装置还包括放纸组件和收纸组件, 如图 3所示 , 刀模辊 1和模辊 2固定在机架 200上, 机架 200、 驱动系统 300固定在底座 100上 , 放纸组件 (图中未示出) 固定在进料口处, 收纸组件 400固定在出料口处的机 架 200上。 放纸组件上缠绕有 PET垫纸 3, PET垫纸 3通过导向辊在滚切组件处与 极片一同输入上下辊之间, 通过辊刀刃口切断极片而不切透垫纸, PET垫纸通过 上下辊后, 经过导向辊, 还可以经毛刷组件刷去残留在垫纸上的废料, 再经过 纠偏组件, 最后收卷于收纸组件 400, 从而实现垫层的可循环使用。
[29] 在一种实施例中, 驱动系统的结构如图 4所示, 包括伺服电机 301、 联轴器 303 、 蜗轮蜗杆减速器 304和主动齿轮 305, 伺服电机 301安装在电机支座 302上, 蜗 轮蜗杆减速器 304的输入端通过联轴器 303与伺服电机 301的动力输出端连接, 其 输出端与主动齿轮 305连接。 主动齿轮 305与模辊上的传动齿轮相啮合, 模辊的 传动齿轮又与刀模辊上的从动齿轮啮合。 这样, 由伺服电机 301提供动力, 通过 主动齿轮 305把动力传输到模辊, 再由模辊的传动齿轮通过刀模辊的从动齿轮带 动刀模辊转动, 完成滚动模切加工。
[30] 在釆用圆压圆方式模切电池极片吋, 电池极片和上下模辊之间的摩擦力不均匀 , 导致电池极片切割的尺寸不一致。 为解决这一问题, 在另一实施例中, 如图 5 、 6所示, 在刀模辊 1的刀模线 11刀口的底部之间加了一层一定厚度的泡棉 4, 泡 棉 4的高度大于刀模线的高度。 在模切吋, 泡棉 4与电池极片紧密贴合, 既增加 了摩擦力, 又使摩擦力比较均匀, 因此可防止电池极片切割后尺寸不一致。 但 泡棉太厚, 上下刀辊相互挤压, 会导致极片挤压变形起折; 泡棉太薄, 上下辊 刀之间极片的磨擦力不够, 又会导致极片有相对滑动的现象。 为防止起折和尺 寸不一致的问题, 需要选用适当厚度的泡棉, 本实施例中, 泡棉比刀刃高出高 度 H为 0.2_0.3mm, 既可解决电池极片切割尺寸不一致的问题, 又可解决切割后 极片起皱的问题。
[31] 在又一实施例中, 刀模辊上具有多个单元的刀模线, 如图 7所示, 刀模辊的轴 向具有两个单元的刀模线, 围绕刀模辊的圆周也具有多个单元的刀模线, 每个 单元的刀模线可模切出一个单张极片。 为防止刀刃出现崩齿, 如图 8所示, 在相 邻单元的相邻刀模线 11之间设有间距 12, 相邻刀模线之间的间距为 1.3mm-1.7mm
。 通过在相邻刀模线之间设计间距, 可消除极片相交处的内应力, 防止极片相 交处的刀刃出现崩齿, 并且还解决了排废料难的问题, 使废料可方便地从相邻 刀模线之间的间距中排出, 而且还解决了上下齿轮的模数问题。
本实施例中, 在刀模辊的表面沿其轴向方向可设置两个或两个以上刀模线, 这 样可同吋并排切割出多个需要的极片。 或者在刀模辊的表面沿刀模辊的圆周方 向设置两个或两个以上刀模线。 这样在刀模辊的一个转动周期中, 可依次切割 出多个需要的极片。
经过上述改进后, 使现有的圆压圆模切装置能够很好地适用于模切金属材质
[34] 釆用本实用新型的圆压圆模切装置, 因送料和模切可连续进行, 因而提高了工 作效率。 并且在极片材料的滚压模切过程中, 同吋进行切割的只有位于刀模辊 同一母线上的刀模线的少量部位, 所需作用力较小, 相应地刀模线的受力也较 小, 因此刀模线变形很小, 电池极片的尺寸稳定一致, 因而刀模线可在较大尺 寸范围内分布, 实现较大尺寸的极片模切。 由于刀模线模切极片吋是在垫层上 渐进挤压、 切入、 切断极片的, 因而模切后的电池极片切边整齐, 减少了毛刺
[35] 以上内容是结合具体的实施方式对本发明所作的进一步详细说明, 不能认定本 发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通技术人员 来说, 在不脱离本发明构思的前提下, 还可以做出若干简单推演或替换, 都应 当视为属于本发明的保护范围。
