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.

摘要： A laser welder alignment system includes a laser welder, a camera associated with the laser welder configured to capture images of a loaded product within the laser welder, and a controller in communicative association with the laser welder and the camera. The controller receives visualization data from the camera and, based on the visualization data, forms and sends positioning instructions to the laser welder instructing the laser welder so as to position the loaded product at a proper weld start. The laser welder alignment system also verifies proper positioning of the loaded product within the laser welder, and verifies proper rotation of the loaded component by determining whether the rotating product has a wobble that exceeds a pre-defined wobble tolerance.

摘要： The invention relates to a method and a laser machining device 10 for machining a workpiece 13. The laser machining device 10 has a laser 11 for generating a laser beam 12, which is deflected by way of a deflecting device 15 in accordance with a pattern defined by a control unit 14 and is directed onto a workpiece surface 17 of a workpiece 13, which surface is to be machined. The point of impingement 18 of the deflected laser beam 12b on the workpiece surface 17 is guided along at least one spiral path within a circular hatched area 16. The spiral path 19 is characterized by spiral path parameters. One spiral path parameter is the line spacing a between neighboring points of intersection P of the spiral path 19 with an axis running through the center point M of the spiral path 19.

摘要： The thermal processing device includes a stage, a continuous wave electromagnetic radiation source, a series of lenses, a translation mechanism, a detection module, a three-dimensional auto-focus, and a computer system. The stage is configured to receive a substrate thereon. The continuous wave electromagnetic radiation source is disposed adjacent the stage, and is configured to emit continuous wave electromagnetic radiation along a path towards the substrate. The series of lenses is disposed between the continuous wave electromagnetic radiation source and the stage, and are configured to condense the continuous wave electromagnetic radiation into a line of continuous wave electromagnetic radiation on a surface of the substrate. The translation mechanism is configured to translate the stage and the line of continuous wave electromagnetic radiation relative to one another. The detection module is positioned within the path, and is configured to detect continuous wave electromagnetic radiation.

摘要： A filter device for gas filtration has a filter housing and a plate-type filter element disposed in the filter housing. The filter element is provided with a raw side and a clean side and is flowed through from the raw side to the clean side by a gas to be purified in a direction that is orthogonal to a filter plane of the plate-type filter element. A cover element is connected to the filter housing by a tensioning bolt penetrating the filter element. The filter element has a cutout forming a clean-side gas collecting chamber. A sealing element is arranged on the clean side of the filter element and frames the gas collecting chamber at least partially. A sealing eye is connected to the sealing element and arranged in the gas collecting chamber, wherein the tensioning bolt is guided through the sealing eye.
