Abstract

La présente invention concerne un procédé permettant de détecter un défaut de buse d'aspiration, consistant : à envoyer un rayon de lumière dans le trou intérieur d'une buse d'aspiration depuis n'importe quelle extrémité d'une buse d'aspiration ; à collecter, à l'autre extrémité de la buse d'aspiration, une image du rayon de lumière traversant le trou intérieur de la buse d'aspiration ; à déterminer, en analysant l'image, si la buse d'aspiration a un défaut. En lien avec ce procédé, l'invention concerne aussi un dispositif permettant de détecter un défaut de buse d'aspiration, comprenant un support de détection et une source de lumière fixée sur le support de détection. Une extrémité de la buse d'aspiration à détecter est un port d'aspiration et l'autre est un port de connexion. La buse d'aspiration est disposée au-dessus de la source de lumière, et le port d'aspiration ou le port de connexion est aligné avec la source de lumière. L'image peut réfléchir la condition dans le trou intérieur de la buse d'aspiration pour aider à déterminer si la buse d'aspiration a un défaut comme un blocage ou une fracture, détectant ainsi complètement la condition du trou intérieur de la buse d'aspiration.
