摘要： A laser processing machine includes a cavity, a laser system, at least one processing platform, and at least one upper motion platform. The laser system is disposed at a lower part inside the cavity, and used for outputting a laser beam. A traveling direction of the laser beam is opposite to the gravity direction. The processing platform is disposed at an upper part inside the cavity, and includes an adsorption surface and a connection surface facing each other. The adsorption surface is located below the connection surface, and is used for adsorbing a workpiece. The upper motion platform is disposed at the upper part inside the cavity, and is correspondingly connected to the connection surface of the processing platform, in order to cause the processing platform to move.

摘要： A double-sided machining laser machine tool is provided for machining a workpiece having opposite first and second machining surfaces. The machine tool includes a laser machining apparatus and a mechanical arm. The laser machining apparatus includes a laser source, a light guiding-and-focusing lens assembly, a three-axis moving stage, an optical inspection device, and a control device. The control device drives the three-axis moving stage moving the workpiece to a machining horizontal coordinate and a machining altitude according to a current horizontal coordinate and a current altitude of the work piece. The control device drives the laser source and the light guiding-and-focusing lens assembly focusing the laser light to the first machining surface. The mechanical arm is controlled by the control device. When the machining of the first machining surface is finished, the mechanical arm flips over the workpiece to allow the laser machining apparatus to machine the second machining surface.

摘要： A double-directional machining laser machine tool includes a focused laser source, a lifting platform, a motion platform, a rotating platform, a height sensor, a vision module, and a control device. The control device drives, according to a distance detected by the height sensor, the lifting platform to lift the focused laser source up or down, and drives, according to an image, the motion platform to displace the bearing table, so as to enable a first laser beam outputted by the focused laser source forms a first recessed hole at a predetermined position on a first surface of a workpiece. The control device drives the rotating platform to rotate the workpiece, so as to enable the first laser beam forms a second recessed hole on a second surface of the workpiece, and the first recessed hole is in communication with the second recessed hole, so as to form a deep hole.
