Background technique

With the development of science and technology, laser technology is becoming increasingly mature and widely used in various industries. However, the traditional laser welding and laser marking are all manually operated on the laser marking machine and the laser welding machine respectively. During laser marking, it is necessary to accurately place the workpiece to be marked manually according to the laser light preset point of the workbench for laser marking. The placement position needs to be tested many times, resulting in low work efficiency, and the workpiece is often scrapped due to manual errors. During laser welding, the operator needs to fit the edge of the workpiece to be welded to intersect with the preset point of laser light on the workbench, start the welding switch, and perform spot welding. Due to manual operation, errors are easy to occur, and even welding failures are caused. The work efficiency is low, the quality is not guaranteed, and high requirements cannot be met. Therefore, the laser welding and marking all-in-one machine came into being.
