    • A laser cutting system, including a steering mirror assembly for directing a laser beam through a predetermined cutting path along a workpiece or substrate material. The steering mirror assembly includes a base, and a mirror pivotally supported on the base by a flexure assembly which confines pivotal movement of the mirror about a vertical Y-axis and/or about a horizontal X-axis. A pair of electrical actuator assemblies include movable bobbin assemblies connected to the mirror by control rod flexures at locations on the mirror which are spaced 90° apart from one another. In operation, selective electrical energization of the actuator assemblies controls movement of the bobbin assemblies to pivot the mirror about the vertical Y-axis and/or about the horizontal X-axis throughout a number of angular orientations to thereby direct the laser beam through a predetermined cutting operation pattern along the substrate surface to cut materials from the substrate. The flexure arrangements which support the mirror on the base and which connect the bobbin assemblies to the mirror facilitate substantially frictionless movement of the bobbin assemblies and the mirror, which allows the mirror to pivot at high operational speeds during the cutting sequence.
    • 一种激光切割系统,包括用于将激光束沿着工件或基底材料引导通过预定切割路径的转向镜组件。 转向镜组件包括基座和通过弯曲组件枢转地支撑在基座上的反射镜,该挠曲组件限制了反射镜围绕垂直Y轴和/或围绕水平X轴的枢转运动。 一对电致动器组件包括通过控制杆在反射镜上彼此间隔开90°的位置处的弯曲处连接到反射镜的可移动的线轴组件。 在操作中,致动器组件的选择性电激励控制线轴组件的运动,以使反射镜围绕垂直Y轴和/或围绕水平X轴绕整个角度取向枢转,从而将激光束引导通过预定的 沿着基板表面切割操作图案以从基板切割材料。 在底座上支撑反射镜并将筒管组件连接到反射镜上的弯曲装置有助于线轴组件和反射镜的基本无摩擦运动,这允许反射镜在切割顺序期间以高操作速度枢转。
