Title
(EN) LASER CUTTING SYSTEM FOR CUTTING ARTICLES AND FORMING FILTRATION TUBES
(FR) SYSTÈME DE DÉCOUPE AU LASER DESTINÉ À COUPER DES ARTICLES ET À FORMER DES TUBES DE FILTRATION
Abstract
(EN)
A laser cutting system for cutting articles, such as tubes, and method of using the same. The laser cutting system can cut slots, holes, and/or pores into each article or tube to form filtration tubes, for example. The system includes a delivery system for delivering a laser beam from a laser source, at least one mirror, a focusing objective lens, a gas source, and a delivery nozzle. A first stage holds each article in a longitudinal direction, and may rotate the article axially during delivery of the gas and laser beam towards the article and move the article longitudinally relative to the delivery nozzle. A second stage is provided in the system for moving the delivery nozzle relative to the article being held by the first stage. A controller controls actuation of the laser beam and the gas source, and movement of the first stage and the second stage.

L'invention concerne un système de découpe au laser destiné à couper des articles, tels que des tubes, et un procédé d'utilisation associé. Le système de découpe au laser peut découper des fentes, des trous et/ou des pores dans chaque article ou tube pour former des tubes de filtration, par exemple. Le système comprend un système d'émission destiné à émettre un faisceau laser à partir d'une source laser, au moins un miroir, une lentille d'objectif de focalisation, une source de gaz et une buse de distribution. Un premier étage maintient chaque article dans une direction longitudinale, et peut faire tourner l'article axialement pendant la distribution du gaz et l'émission du faisceau laser vers l'article et déplacer l'article longitudinalement par rapport à la buse de distribution. Un second étage présent dans le système est destiné à déplacer la buse de distribution par rapport à l'article qui est maintenu par le premier étage. Un dispositif de commande commande l'actionnement du faisceau laser et de la source de gaz, et le déplacement du premier étage et du second étage.
