Abstract

Máquina para el control automático de calidad de productos cerámicos por visión artificial y análisis de sonido. La máquina consta de dos recintos. En el primero (5) de ellos se analiza la onda sonora obtenida al golpear la pieza para detectar posibles fisuras o defectos internos. En el segundo recinto (6) se analiza la pieza por un sistema de visión artificial al objeto de detectar posibles defectos como esquinas rotas, pieza incompleta, pintado de la pieza incorrecto, dimensiones de la pieza fuera de tolerancias, tono de color incorrecto y demás características detectadas por el sistema de visión por ordenador (1), (2) que la máquina lleva incorporado. La máquina resuelve de forma automática y con mayor fiabilidad el problema del control de calidad de productos cerámicos que en la actualidad es realizado de forma manual.
