Abstract

The invention discloses a laser perforating detection method and a laser cutting machine. A signal processing unit and at least one sensor for detecting signals indicating that laser penetrates through a plate are arranged on a laser head body of the laser cutting machine, and the sensors are located on the outer portion of the laser head body and electrically connected with the signal processingunit. The method comprises the steps that a main control system of the laser cutting machine sends a laser emitting signal to the signal processing unit; the main control system receives a penetrating-through signal fed back by the signal processing unit; in the laser-emitting period of the laser head body, the signal processing unit processes detecting signals of all the sensors, and a signal with a penetrating-through state as a obtained laser perforating state is the penetrating-through signal; and the main control system carries out closed-cycle control over the laser perforating detectingprocess according to the penetrating-through signal. By means of the method, the defect that the cutting technology descends as a fixed duration is set for laser perforating in the existing technology can be overcome.

Description

technical field [0001] The invention relates to laser cutting technology, in particular to a laser perforation detection method and a laser cutting machine. Background technique [0002] Laser cutting equipment often needs to perform laser perforation on the plate when cutting the plate, but the traditional laser cutting equipment cannot distinguish whether the laser penetrates the plate, and can only rely on the time parameters set by the main control system of the laser cutting machine to time End the laser perforation process, but this method will lead to two problems: 1. Due to the interference of various factors during the laser perforation process, it is difficult to maintain a constant value for the laser perforation time. If the time setting is too short, the laser cannot penetrate the plate effectively. 2. Since it is difficult to maintain a fixed value for laser perforation time, users are often conservative when setting this parameter, which will cause waste of p...
