A method and device for laser processing with infinite format

Abstract

The invention discloses a laser processing method for an infinite width and a device. The process is as follows: fixing a workpiece to be processed on a servo platform, controlling the moves of the servo platform to collect and identify a positioning point on the workpiece, and determining initial coordinates of a starting point and an ending point of each line segment to be processed in a motioncoordinate system according to the positioning point; according to the initial coordinates, determining the length, the direction, and the initial processing point of each line segment to be processed, and determining the processing sequence of all line segments and the motion trajectory of the servo platform and a scanning galvanometer; and controlling a synergic movement of the servo platform and the scanning galvanometer according to the determined processing sequence and the motion trajectory to realize the processing of the workpiece to be processed. The laser processing method for the infinite width and the device have the advantages of the simple structure and the convenient use, and are suitable for continuous laser processing of large-width workpiece, so that the efficiency of thelaser processing is greatly improved. The synchronous coordinated movement of the servo platform and the scanning galvanometer achieves the advantages of precision, infinite width and high speed.

Description

technical field [0001] The invention relates to a laser processing method and equipment, which belong to the technical field of laser processing, and in particular to a laser processing method and equipment with an infinite format. Background technique [0002] The laser processing system can be divided into two types: fixed light type and dynamic light type according to whether the laser moves. The processing of the workpiece is typically represented by the traditional lamp-pumped Nd:YAG fixed-light laser cutting system. The advantages of this type of processing method are small error, simple principle, low cost, and high precision. It is suitable for small batches, Scattered processing, and occasions that do not require high speed and efficiency; the disadvantages of this type of processing method are: slow processing speed, low efficiency, small holes and micro holes cannot be processed. The shortcoming of the fixed-light laser cutting system is caused by the slow moveme...
