ã€Abstractsã€‘ The invention discloses a glass ampoule bottle laser sealing method, which comprises the following steps: rotating a glass ampoule bottle; sealing a glass ampoule bottle: the power of the laser beam acting on the glass ampoule bottle is 50-1000 W, and the laser beam The light spot is 20 to 200 mm2. The glass ampoule bottle is melted under the action of the laser beam, and the laser beam is applied for 0.8 to 5 s. After that, the entire sealing process is completed. Before sealing the glass ampoule bottle, the glass ampoule bottle can also be preheated. The power of the preheated laser beam is 50-200 W, the laser beam spot is 20-200 mm2, and the preheating time is 0.5-3 s. The invention uses the CO2 laser instead of the flame sealing, improves the production environment of the injection medicine and improves the production quality of the injection; the beam parameters of the laser can be easily controlled, and is suitable for the laser sealing of glass ampoule bottles of various sizes.
