Abstract

Dispositif de contrôle de la qualité de l'arête d'un corps élastique, tel que la lame de raclage de toner d'une photocopieuse ou le balai d'essuie-glace d'un véhicule, dans laquelle la qualité de l'arête d'une partie de bord a une influence directe sur la fonction du produit. Ce dispositif de contrôle comporte un plateau (1) sur lequel est fixé un corps élastique (B) destiné à être examiné, une aiguille de contact (4) supportée par un détecteur d'accélération piézo-électrique (5) de sorte que l'aiguille de contact (4) puisse venir en contact avec une arête (C) de la partie de bord du corps élastique (B), et une unité de transfert (2) destinée à déplacer le corps élastique (B) en même temps que le plateau (1) par rapport à l'aiguille de contact (4). Le corps élastique (B) se déplace par rapport à l'aiguille de contact (4) qui est en contact avec l'arête (C) du corps élastique (B), de sorte que la variation de la pression de contact de l'aiguille (4) est convertie en des signaux de tension par le détecteur (5). On compare un niveau de signal de tension converti avec un niveau de signal de tension de référence, et on code en binaire ce signal selon que la valeur absolue du niveau du signal de tension effectif est supérieure au niveau du signal de tension de référence. En fonction des signaux codés binaire, il est ainsi possible de déterminer si l'arête (C) de la partie de bord du corps élastique (B) présente un quelconque défaut.
