Technical Field

[0002] In the market, the basic structure of a vacuum adsorption platform is usually assembled or glued by stacking two or more layers of materials. This multi-layer structure usually includes a panel, a frame, a filler, and a bottom plate. Traditional frames are usually formed by lapping plate-shaped profiles into a frame structure and then welding, or an inner frame is welded inside the frame for zoning or local strength enhancement. However, welding not only increases energy consumption but also generates stress on the frame, resulting in deformation. As the number of welding points increases, this deformation becomes more significant, thus affecting the final accuracy of the finished product. To meet the flatness requirements, it is necessary to add calibration and adjustment processes, forming a repair-type production process flow. At the same time, the release of stress during welding also poses a hidden danger to product quality, increasing the uncertainty of the product during use. Content of the Utility Model
