本发明还提供一种激光切割方法，其包括以下步骤：
S1：将料片从上料单元送至切割单元；
S2：对料片进行切割；
S3：切割后的料片被加热同时进行裂片；
S4：裂片后的料片被取出。
其中，步骤S1中，所述的料片是通过上料机器手从上料单元取出，每次可以取一片或者多片，然后将料片送至定位单元，所述的定位单元伸出接住待切割材料，退回原始位置时同时对料片进行定位，定位准确后的料片被转载机器手取出并送至切割单元。
装载料片的料盒在推料进给电缸的带动下移动，待上料机械手将料片取完后，空料盒被推送至回收单元，上料机械手再次取出下一个料盒。
所述的料盘放置在钢柱滚轮铺成的流水线上，由三个推料进给电缸推动，料盘到位后，有接近传感器检测，阻挡气缸阻挡，防止料盘移动，由光电感应器判断料盒中是否有料。
步骤S2中，对料片进行切割，加工产品真圆度<3μm。
切割完成后，通过转载机器手再次将切割完成的料片取出。
步骤S3中，所述的料片通过裂片加热机构来加热裂片，该加热机构包括固定本体511，升降电机512，升降导向机构513，隔热机构514，第一加热体515以及第二加热体516。所述的升降电机512被固定在固定本体511上，并通过升降导向机构513与第一加热体515以及第二加热体516相连，所述的隔热机构514设置在升降导向机构513与第一加热体515之间，同样的升降导向机构513与第二加热体516之间也设置了隔热机构514。
所述的第一加热体515以及第二加热体516的温度分别受加热温控系统52控制，且加热温控系统52可以分别独立对第一加热体515以及第二加热体516进行加热，每个加热体的可以温度不同，而且第一加热体515以及第二加热体516可以分别设置2个，这样就同时可 以有4个加热体在工作，第一加热体515以及第二加热体516通过升降导向机构513可以分别动作，进行升降。所述的第一加热体515以及第二加热体516采用黄铜材质较佳，导热性好的同时不损伤料片。
如图6所示，所述的裂片旋转台53包括4个工位，分别设置为上下料位，第一裂片加工位，第二裂片加工位以及取外框位。该裂片旋转台53包括内置高速旋转马达531，该内置高速旋转马达531可以驱动工位旋转至需要的位置。所述的料片通过真空吸附的方式被固定在工位上，
第一加热体515以及第二加热体516被加热到预设温度后可加对料片进行加热裂片，以玻璃为例，所述的第一加热体515对该玻璃料片的外圆进行裂片，所述的第二加热体516对该玻璃料片的内圆进行裂片，具体工作过程为：玻璃料片被固定在上下料位后，内置高速旋转马达531旋转90度，到第一裂片加工位，加热温度200度，较佳的范围为180～220度，经过5秒左右，较佳的范围为4～7秒，该玻璃料片外圆不要的部分被裂掉；内置高速旋转马达531再旋转90度，到第二裂片加工位，加热200度，经过5秒左右，较佳的范围为4～7秒，该玻璃料片內圆的部分会被裂掉，掉下去的部分通过裂片旋转台53中的小孔直接回收。内置高速旋转马达531再旋转90度，真空吸嘴会把裂片好的玻璃料片吸起来取出，喷掉外径不要的部分再放回去后，内置高速旋转马达531再次旋转90度，重新回到到前面的上下料位，一次完整的加热裂片过程完成。
步骤S4：裂片后的料片通过下料机械手取出。
本发明的激光切割装置以及激光切割方法通过加热裂片的方式，每次可以裂片多个料片，而且能够提高裂片的精度以及效率。
以上所述仅为本发明的实施方式，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。
