Latest Patents
One of Lewan's latest patents is titled "Vision-based rotary part offset correction for weld toolpathing." This invention provides an improved laser weld process control system and method. The system utilizes a machine vision camera to detect deviations between a pre-programmed laser beam toolpath and the gap centerpoint between two parts being welded. The parts are secured to a rotatable fixture, which can rotate through a corrective angle to align the gap centerpoint with the laser beam toolpath, even in real time during the application of laser energy. Additionally, the system can correct for vertical misalignment of the laser focal point by adjusting the vertical separation of the laser unit relative to the fixture.
Another significant patent is the "Powder material mass flow rate measuring apparatus for additive manufacturing." This assembly measures the mass flow rate of metal powder material during direct metal deposition. A detection strip is placed in the gas-blown metal powder material flow path, where it is fixed at one end and suspended at the other. The flowing metal powder particles induce displacement in the detection strip, which is measured by a sensor. The amount of displacement correlates to the mass of metal powder flowing through the system, ensuring accurate measurements for additive manufacturing processes.
