Glass plate edge tightness testing device and method Technical Field The disclosure relates to the technical field of glass plate manufacturing, in particular to a glass plate edge tightness testing device and method. Background The float glass plate is annealed in an annealing kiln in the production process, and the temperature of the float glass plate is properly controlled by the annealing kiln to cool the float glass plate to a normal temperature state, so that the thermal stress generated in the float glass plate is controlled within an allowable range. During the annealing process, the float glass sheet will develop tensile and compressive stresses, and when the glass is in a plastic state, the glass body with higher temperature will be subjected to tensile stress, and when the temperature is lower, compressive stress is reflected, and when the glass is in an elastomer, the situation is just opposite. Since the tensile stress and the compressive stress cannot be visually seen, when the tensile stress of the edge is too large, longitudinal burst is easily caused, and when the compressive stress of the edge is too large, transverse burst is easily caused. At present, the tightness of the edge of the online glass plate is judged mainly by manually lifting and laterally viewing a gap between the glass plate and a roller way by a worker with abundant experience, so that uncertainty and adjustment difficulty are brought, and a large loss is caused once the glass plate is fried.
