This patented technology includes a workbench with a pressure testing assembly mounted on one side. The assembly includes a pressure head directed toward the automotive glass. A vertically moving cylinder moves the pressure head toward the glass and a horizontally moving cylinder moves the pressure head horizontally. On the other side of the workbench is a placement assembly for the automotive glass. The placement assembly includes a fixed seat and a sliding seat that can move toward and away from the fixed seat. The fixed and sliding seats are symmetrically arranged. The sliding seat can slide on the workbench and is secured to the workbench with bolts. Both the fixed and sliding seats are equipped with clamping devices that clamp the automotive glass placed between the fixed and sliding seats. This testing device offers excellent versatility and high efficiency, ensuring test accuracy.
