Description

说 明 书 平板材料的切割机构及其工作方法 技术领域
本发明涉及平板材料切割设备领域, 特别是涉及一种平板材料的 切割机构及其工作方法。
背景技术
目前, 对平板材料的切割可以分为两种方法, 一是保持切割机构 的空间位置不动, 刀头压在平板材料的表面上, 通过移动被切割的平 板材料的空间位置, 进而实现对平板材料的切割; 二是保持平板材料 的空间位置不变, 通过移动切割机构的空间位置进而实现对平板材料 的切割。
现今比较常用的是第二种切割方法, 在切割机构的控制中, 比较 重要的是控制切割刀头的落下和抬起(本说明书中所述的 "落下', 和 "抬起,, 是指切割刀头相对于平板材料来说的, 即切割刀头接近平板 材料为 "落下", 远离平板材料为 "抬起,, ;同理, "顶端"、 "上方" 是 指远离平板材料的一端, "底端 " 是指接近平板材料的一端), 其一般 有两种驱动方式: 第一种是由气缸配合直线导轨驱动刀头落下、 抬起, 这种结构是一种超静定结构, 对制造、 安装要求较高, 需要通过安装 调整, 保证刀头垂直于平板材料方向上的精度, 且在使用过程中容易 产生阻卡; 第二种是利用气缸驱动整个切割刀头总成落下、 抬起, 这 种结构使气缸负载增大, 势必造成气缸成本增加, 且切割刀头落下时, 对平板材料, 例如玻璃会产生的冲击较大, 尤其在切割薄玻璃时, 经 常会将薄玻璃压碎。 并且, 这两种方式都不能根据玻璃板的不同厚度 准确地调节刀头行程, 现场板厚改变时, 往往需要反复调整才能将切 割刀头调整到合适位置。
针对平板材料厚度发生改变时, 需要改变切割刀头行程的技术问 题, 市售产品提出了一种解决方案, 即在切割刀头总成上安装厚度检 测装置, 通过对待切割板材的厚度进行检测, 进而调整气缸驱动整个 切割刀头总成落下、 抬起的行程。 例如, 在切割厚度为 5mm玻璃时, 切割刀头总成在 Z轴的行程为 45mm, Z轴指与平板材料相垂直的轴; 在切割厚度为 2腿的玻璃时, 通过厚度检测装置可以得知待切割玻璃 的厚度减少了 3匪, 则气缸在控制切割刀头总成在 Z轴的行程变更为 48腿。 通过安装厚度检测装置, 可以根据玻璃板的不同厚度准确地及 时调节刀头行程, 但是在实际生产过程中也出现以下不足之处:
1、 利用气缸驱动整个切割刀头总成落下、 抬起, 气缸负载较大, 整体工作效率低, 工作成本居高不下;
2、 通过厚度检测装置控制切割刀头行程的可靠性差, 一旦厚度检 测装置失灵或出现误差, 会导致被切割平板材料被切割刀头压碎或导 致切割刀头不能接触到平板材料, 进而导致无法切割。
发明内容
本发明的目的是针对现有技术中存在的技术缺陷, 而提供一种降 低气缸驱动负载且可靠性强的平板材料的切割机构及其工作方法。 为实现本发明的目的所采用的技术方案是: 一种平板材料的切割 机构, 包括刀头装置, 所述刀头装置包括底板、 大气缸、 切割刀头和 刀头轴组件, 刀头轴组件包括刀头轴和轴承, 所述大气缸固定安装在 与待切割平板材料垂直的底板上; 刀头轴组件的底端安装有切割刀头, 其顶端穿过大气缸, 并由大气缸控制刀头轴组件的落下、 抬起, 其特 的限位装置, 所述限位装置安装在底板上远离平板材料的一端; 所述 限位装置包括用于限制刀头轴组件抬升高度的定位组件和位移调节组 件, 所述位移调节组件位于刀头轴組件和定位组件之间, 并安装在刀 头轴组件或定位组件两者之一上, 通过位移调节, 可与另外一个形成 间隔。
上述刀头轴组件包括刀头轴和轴承, 轴承可以使上述气缸不跟随 刀头轴旋转, 刀头轴的顶端由轴承的内圈支撑。 通过大气缸和轴承的 共同约束, 刀头轴便可以牢固的稳定在垂直于平板材料的方向上, 从 而精确的对平板材料进行切割。

( 4 )调整切割刀头或平板材料, 使切割刀头对准下一个切割始点 后, 大气缸控制刀头轴組件将切割刀头下降到切割材料表面, 开始切 割;
( 5 ) 重复上述步骤, 直至完成所有切割任务后, 比例阀通过控制 大气缸和定位组件共同作用控制刀头轴组件、 位移调节组件及定位轴 向远离平板材料方向运动, 恢复至起始位置。
上述限位装置也可以不安装在底板远离平板材料的一端, 而是和 大气缸并排安装, 限位装置可以通过一根杆来限制刀头轴组件的抬升 高度, 即, 这根杆一端连在限位装置上, 并且与平板材料平行, 限位 装置可以控制这根杆在垂直于平板材料方向上接近或远离平板材料 , 从而形成一个机械限位, 从而可以限制刀头轴组件的抬升高度。 在工 作时, 限位装置和所述^^可随着刀头轴组件的落下, 抬起一同落下, 抬起。

上述步骤(2 ) 中的切割压力是由比例阀预先设定并控制的, 切割 压力的大小与待切割平板材料的硬度和厚度有关。
与现有技术相比, 本发明的有益效果是:
( 1 ) 本发明利用气缸驱动刀头轴组件和切割刀头的落下、 抬起, 相对于现有技术中气缸驱动整个切割刀头总成来说, 气缸负载变小, 运行速度更快; 刀头轴组件和切割刀头在抬起时在限位装置的作用下, 仅需抬起位移调节组件形成的间隔这一段距离, 相比于现有技术来说, 能够节省大量的能耗, 提升工作效率。
( 2 )本发明适用于不同厚度的平板材料的切割, 无论被切割平板 材料的厚度是多少, 切割刀头落下到平板材料表面时即可以开始切割, 从而改变了现有技术中通过厚度检测装置控制切割刀头总成的行程而 带来可靠性差的缺陷。

8、 根据权利要求 1-6之一所述的一种平板材料的切割机构, 其特 征在于所述间隔为 3mm。
9、 根据权利要求 1所述的一种平板材料的切割机构, 其特征在于 所述平板材料为玻璃。
10、 上述平板材料的切割机构的工作方法, 包括以下步骤:
( 1 )调整切割刀头或平板材料, 使切割刀头位于切割始点, 比例 阀控制大气缸的气体压力, 大气缸控制安装有切割刀头的刀头轴组件 落下, 定位轴及位移调节组件跟随刀头轴组件向接近平板材料方向运 动, 直至切割刀头运动到待切割平板材料的表面后停止运动;
( 2 ) 定位组件固定定位轴; 位移调节组件通过调整, 形成间隔;
( 3 )切割刀头开始切割, 在到达切割终点后, 大气缸控制刀头轴 组件将切割刀头抬起, 抬起距离为位移调节组件形成的间隔;
( 4 )调整切割刀头或平板材料, 使切割刀头对准下一个切割始点 后, 大气缸控制刀头轴组件将切割刀头下降到切割材料表面, 开始切 割;
( 5 ) 重复上述步骤, 直至完成所有切割任务后, 比例阀通过控制 大气缸和定位组件共同作用控制刀头轴组件、 位移调节组件及定位轴 向远离平板材料方向运动, 恢复至起始位置。
