图 6为本发明自动涂布机的所述张力控制件 15的另一个实施例 的结构示意图。 参考图 6 , 所述张力控制件 15具有固定部 151及沿 所述固定部 151延伸出的弹性部 152。 所述弹性部 152进一步包 第 一弹性部 1521和第二弹性部 1522。 所述第一弹性部 1521的一端垂 直于所述固定部 151， 所述第一弹性部 1521 的另一端弯折延伸形成 所述第二弹性部 1522。且所述张力控制件 15的所述第二弹性部 1522 分别固定连接于所述连接件 14的两端，所述张力控制件 15的所述固 定部 151分别与所述滑动块 13的另一端固定连接。 较佳地， 所述张 力控制件 15可由一不锈钢片弯折成形成。 由于不锈钢具有良好的弹 性， 因而所述张力控制件 15的所述弹性部 152能消除所述直线驱动 装置引起所述第二连接装置 14的抖动。
所述机架 10由铝材料制成， 所述滑轨 17由不锈钢材料制成。 由 于铝材料的密度低， 比较柔软，而不锈钢材料的相对密度高，硬度大， 在涂布机工作的过程中， 两种材料的相互配合可提高所述滑轨 17与 所述机架 10之间的自适应性， 减少所述滑轨 17因所述机架 10产生 的抖动。
可理解地， 所述伺服电机 161还可接一控制器 19。 所述控制器 19与所述伺服电机 161电气连接。 通过编程， 所述控制器 19可控制 所述伺服电机 161的转速， 从而控制所述湿膜制备装置 12的运行速 度和运行距离， 使所述自动涂布机的涂布方式更灵活， 且提高了所述 自动涂布机的涂布质量。 如上所述， 本发明提供了一种自动涂布机， 由于本发明提供的自 动涂布机在连接件 14的两端分别固定连接有两个具有固定部 151和 弹性部 152的张力控制件 15， 该张力控制件 15的弹性部 152有效地 消除了所述连接件 15 因直线驱动装置而引起的抖动， 从而消除了所 述湿膜制备装置 12因所述连接件 15的抖动而产生的抖动， 因而， 本 发明的自动涂布机涂布在材料上的涂料或油墨均匀，从而提高了涂布 材料的质量和涂布机的精度。
以上结合最佳实施例对本发明进行了描述，但本发明并不局限于 以上揭示的实施例， 而应当涵盖各种根据本发明的本质进行的修改、 等效组合。
