Abstract

L’invention concerne un équipement de cuisson d'un appareil de fabrication de lampe fluorescente cathodique. Dans l’équipement conventionnel de cuisson d'un appareil de fabrication de lampe fluorescente cathodique froide, on rencontre souvent le problème de déformation d’une ampoule lors d’un processus d’enlèvement d’un matériau organique inclus à la fois dans une couche de protection et dans une substance fluorescente enduite dans l'ampoule, dans la mesure où l’ampoule est chauffée de manière perpendiculaire et se voit injecter de l’oxygène ou de l’azote à travers une buse depuis le haut de celle-ci, tandis que la partie supérieure de l'ampoule est saisie par une tête d’un élément rotatif mis en rotation par une unité d'indexage. Selon la présente invention, comme le montre les figures 3 à 10, à la fois une unité d'entraînement 130 et un système d'alimentation en air chaud 140 sont installés sur les côtés du corps principal, respectivement, une unité de chauffage 150 est installée sur le corps principal 100 dans le sens de la longueur, une unité à galet 160 faisant tourner un tube de quartz 151 est installée entre l’unité de chauffage 150, une unité à bloc de transport 170 est installée dans la partie inférieure de l'unité à galet 160, et une unité à chaîne de transport 180 est installée à la fois aux extrémités et à la partie inférieure de l’unité à bloc de transport 170 afin de transférer le tube de quartz 151 pour maintenir le tube de quartz 151 perpendiculaire, étant disposé sur l'unité à galet 160 par l’unité à bloc de transport 170. Comme une pluralité d'ampoules enduites d’une couche de protection et de substance fluorescente est introduite dans le tube de quartz 151 portant l'unité à galet 160, les ampoules se déplacent horizontalement comme le tube de quartz 151, et les ampoules sont chauffées indirectement à travers le tube de quartz 151 par l’unité de chauffage 150 et le système d'alimentation en air chaud 140 de sorte qu’un matériau organique inclus à la fois dans la couche de protection et dans la substance fluorescente est éliminé et enlevé, en évitant toute déformation de l'ampoule.
