Abstract

DETECÇÃO DE SEPARAÇÃO DE METAL DE MOLDE DE FUNDIÇÃO. Metal pode ser separado de um molde de fundição durante o processo de fundição. Um sistema de detecção pode monitorar o molde e determinar se o metal foi separado do molde. O sistema de detecção pode incluir uma câmera, uma fonte de luz, e um sistema de computador. A câmera e a fonte de luz podem ser dispostas em lados opostos do molde de fundição e posicionadas para apontarem, ambas, na direção do molde. O sistema de computador pode detectar se qualquer luz é visível entre o molde e o metal, com base nos dados recebidos da câmera. O sistema de computador pode, então, determinar que o metal foi separado do molde com base na luz detectada.FOUNDRY MOLD METAL SEPARATION DETECTION. Metal can be separated from a casting mold during the casting process. A detection system can monitor the mold and determine if metal has separated from the mold. The detection system may include a camera, a light source, and a computer system. The camera and light source can be placed on opposite sides of the casting mold and positioned to both point towards the mold. The computer system can detect whether any light is visible between the mold and the metal, based on data received from the camera. The computer system can then determine that the metal has separated from the mold based on the detected light.
