Abstract

L'invention concerne un procédé de meulage de bord d'un substrat de verre de panneau d'affichage qui consiste à: Étape 1. Acheminer un substrat de verre à meuler de panneau d'affichage vers un dispositif de meulage, et positionner le substrat de verre de façon à attendre une pierre à affiler du dispositif de meulage afin que celle-ci effectue un meulage de bord ; Étape 2. Former une première plaque barrière et une seconde plaque barrière ; Étape 3. Déplacer la première plaque barrière de sorte que celle-ci soit en contact avec la surface supérieure du substrat de verre et déplacer la seconde plaque barrière de sorte que celle-ci soit en contact avec la surface inférieure du substrat de verre ; et Étape 4. Effectuer une opération de meulage de bord. Selon le procédé de meulage de bord, par un agencement des plaques barrière entre la zone de meulage et la zone de non meulage du substrat de verre, les plaques barrière empêchent la poussière de se déposer sur le substrat de verre, et ce qui permet d'éviter de manière efficace aux copeaux de verre, générés lorsque le dispositif de meulage meule la zone à meuler du substrat de verre, de voler sur la zone de non meulage du substrat de verre, et également de protéger efficacement la surface de la zone de non meulage et d'empêcher la surface de celle-ci d'être endommagée.
