ACOUSTIC EMISSION SYSTEM AND METHOD FOR ON-LINE MEASUREMENT OF GLASS BREAK ENERGY

摘要

An acoustic emission system and method are described herein that detect the glass break energy (or another parameter) that is created when a glass sheet (150) is scored and broken. In the preferred embodiment, the acoustic emission system (100) includes an acoustic emission sensor (102), a data acquisition system (104) and a processor (106). The acoustic emission sensor (102) interfaces with a glass sheet (150) and generates of acoustic emission waveforms (108) that are created when the glass sheet (150) was scored and broken. The data acquisition system (105) records the acoustic emission signals (108). And, the processor (106) processes the recorded acoustic emission signals to determine the glass break energy (or another parameter). Then, the processor (106) can use the glass break energy (or another parameter) to determine the quality of an edge of the broken glass sheet (150). In addition, the processor ( 106) can use the glass break energy (or another parameter) as feedback to adjust the scoring and breaking of subsequent glass sheets (150).
