In June 2026, information from the State Intellectual Property Office showed that Suzhou Delong Laser Co., Ltd. applied for a patent called “Laser Welding Test Platform”.
The application publication number is CN122210160A, the application number is CN202610399245.9, the application publication date is June 16, 2026, and the application date is March 30, 2026.
The patent summary shows that the invention relates to a laser welding test stage, including a stage bottom plate. An alignment slide installation bottom plate is connected to the stage bottom plate. A multi-axis alignment slide is connected to the alignment slide installation bottom plate. A lower adsorption stage adapter plate is connected to the multi-axis alignment slide and the lower adsorption stage is connected to the lower adsorption stage adapter plate.
One side of the carrier bottom plate is connected to a carrier vertical plate, a linear guide rail pair is connected to the carrier vertical plate, an upper adsorption platform installation vertical plate is connected to the linear guide rail pair, and an upper adsorption platform is connected to the upper adsorption platform installation vertical plate.
The bottom surface of the upper adsorption platform is provided with a soft boss for sucking back the chip board. The soft boss corresponds to the lower adsorption platform. A piezoelectric sensor is embedded in the upper adsorption platform. A transmission screw rod is connected to the vertical plate of the carrier platform. A sliding block is slidingly connected to the transmission screw rod. The sliding block is synchronously connected to the upper adsorption platform.
This invention effectively improves production efficiency and achieves cost savings.
