Description

一种电池极片激光切割装置 技术领域
本发明属于汽车制造技术领域， 特别涉及到用于动力电池极片生产过程中的一种电池 极片激光切割装置。 背景技术
混合动力车或电动车所用到的动力电池极片是将磷酸铁锂材料均匀涂覆在铜箔 （负 极） 和铝箔 （正极） 的两侧， 然后通过切割设备将极片切割成特定的形状。 目前国内汽车 生产企业中用的切割设备大多是采用冲切和滚切设备， 采用冲切和滚切设备来切割电池极 片时， 切出来的极片毛刺比较多 （特别是负极片）、 切边掉粉严重， 严重影响了电池极片 的质量。 此外， 这两种切割设备中的刀模需要频繁更换， 不利于大规模连续化生产， 同时 也增加了设备后期的维护成本。 发明内容
本发明所要解决的技术问题在于， 针对现有技术的不足， 提供一种电池极片激光切割 装置， 该装置切割质量高、 实用性强。
本发明所要解决的技术问题是通过如下技术方案实现的：
电池极片激光切割装置包括控制单元和激光切割头系统， 激光切割头系统包括激光发 生器和激光切割头， 关键在于所述激光切割头系统的下方设置有真空吸附装置， 所述激光 切割头系统和真空吸附装置之间可相对做水平方向的运动。
在切割电池极片时， 首先将电池极片放置在真空吸附装置上， 利用真空作用将电池极 片固定， 然后按照设定程序来控制激光切割头系统和真空吸附装置之间的相对运动， 同时 控制激光切割头系统的工作， 即可将电池极片切割成所需形状。
上述真空吸附装置包括一个密闭腔体及与密闭腔体相通的真空发生器， 所述密闭腔体 的顶面为设有多个吸附通孔的平面基板， 所述平面基板沿电池极片的切割线设有内凹的避 空槽。 密闭腔体与真空发生器共同组成抽真空装置， 将电池极片放在基板上后， 电池极片 会将吸附通孔遮盖住， 在真空发生器的抽真空作用下， 密闭腔体产生负气压， 电池极片就 会被紧紧吸附在平面基板上， 平面基板为平面结构， 可以保证电池极片不产生跷曲或塌陷 的情况； 平面基板沿电池极片的切割线设有内凹的避空槽， 可以防止在激光切割时， 激光 的光束切割到基板上而造成平面基板被切割划伤， 产生凹凸不平的现象， 影响后续电池极 片的切割质量， 同时也延长平面基板的使用寿命。
所述避空槽的局部贯通平面基板形成洞槽。 这样粉尘就会在真空发生器抽真空的作用 下从洞槽处被吸走， 避免长期累积在避空槽处而影响电池极片的切割质量。
该电池极片激光切割装置包括左右支架和架设于左右支架上的前后支架， 所述左右支 架上设置有可沿左右支架运动的平台， 所述真空吸附装置固定在平台上； 所述激光切割头 系统设置在前后支架上并可沿前后支架运动。 在平台左右移动和激光切割头系统前后移动 的相互配合下， 激光切割头系统就可以相对于真空吸附装置做任意水平方向的运动， 从而 可以对电池极片进行各种形状的切割。
所述左右支架和前后支架上均设置有丝杠和驱动丝杠转动的驱动电机， 所述平台通过 导轨滑块安装在左右支架的丝杠上； 所述激光切割头系统通过导轨滑块安装在前后支架的 丝杠上。 利用丝杠和导轨滑块来控制激光切割头系统相对于真空吸附装置的运动， 可以使 得其运动精度高、 磨耗少， 能长时间维持重复定位精度至少为 15μηι， 满足激光切割高精 度的要求。
所述控制单元分别与驱动电机、 激光切割头系统、 真空发生器相连并控制驱动电机、 激光切割头系统、 真空发生器的工作。 所述控制单元可以釆用工控机， 并编制程序来控制 驱动电机、 激光切割头系统、 真空发生器的工作， 因此， 自动化程度大大提高， 减少人工 劳动强度， 并提高控制精度， 从而提高切割质量。
上述控制单元包括基于 PMAC运动控制器的数控系统， 所述基于 PMAC运动控制器 的数控系统通过 X轴电机驱动器和相应的第一编码器与左右支架的驱动电机相连，通过 Υ 轴电机驱动器和相应的第二编码器与前后支架的驱动电机相连。所述 PMAC( Programmable Multi-Axis Controller)是一种可编程多轴运动控制器， 它采用 DSP56300处理器作为 CPU, 可以实现最多 8个坐标系同时运动， 可以通过存储在其内部的程序单独操作， 使用 PMAC 运动控制器作为动力电池极片数控激光切割控制器， 物理结构可以大大简化， 系统设计 和调试过程也变得更简单。通过 PMAC运动控制器来控制驱动电机的动作，可以实现高精 度的激光切割。
所述激光发生器最好采用光纤激光发生器。 光纤激光发生器与传统的切割加工方法相 比， 具有接近衍射极限的光束质量、 高能量转换效率、 高稳定性、 光路校正简单等特点， 同时， 光纤激光发生器采用光纤来传输激光， 具有很高的柔性， 只需要 220/110V交流电 源， 具有功率小、 几乎免维护、 体积小及超长的使用寿命等优点。 光纤激光发生器所输出 的激光束经过准直、 扩束和聚焦之后将光斑直径聚焦到数十个微米甚至几个微米， 光斑功 率密度能达到 108w/cm2 以上， 具有切缝窄、 热影响区小、 切边光滑、切割速度快的特点， 满足电池极片汽化切割的要求， 是传统模切和滚切设备的理想替代设备。
所述激光切割头上设有将激光束导达电池极片表面的可调焦导光镜组， 以使激光束的 对焦更准， 切割效果更好。
本发明有益效果在于： 结构简单， 针对电池极片的特点做针对性的设计， 使得电池极 片的切割质量及效率更高。 附图说明
