Abstract

The invention provides a laser welding machine control system which comprises a walking device, a welding device and a control device. The walking device comprises a servo motor, a ball screw pair and an encoder. A nut of the ball screw pair is fixedly connected with the welding device. A lead screw of the ball screw pair is connected with the servo motor. The servo motor drives the welding device to move. The encoder records the position information and the movement distance of the welding device. The welding device comprises an optoelectronic switch and a laser welding head. The optoelectronic switch detects the welding boundary of strip steel and transmits the boundary information to the control device. The encoder transmits the position information and the movement distance to the control device. The control device controls welding operation.

Description

technical field [0001] The invention belongs to the technical field of strip steel laser welding, and in particular relates to a laser welding machine control system. Background technique [0002] The start-stop control of the laser beam during laser welding is very important. If the laser beam is turned on too late or turned off too early, the edge welding of the strip will be incomplete; if the laser beam is turned on too early or turned off too late, when the laser beam does not touch the strip, it is easy to irradiate other equipment, causing equipment damage . [0003] At present, in welding machines without precise positioning, the start and stop positions of the laser beam are often determined according to the strip width specifications input by the unit. However, there is a certain deviation between the actual strip width and the input data. Therefore, in order to ensure the integrity of the strip joint welding, a certain margin is often left, so that the laser bea...
