Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to a laser cutting and welding device. Background Art

[0002] Laser cutting and welding devices can cut or weld workpieces by laser. In existing laser cutting and welding devices, a clamp is generally set under the laser device. Workers clamp the workpiece on the clamp. After cutting or welding, the laser device needs to stop and wait for the worker to unload and re-clamp, resulting in low production efficiency; in addition, some laser cutting and welding devices use a rotating disk to design a double-station. When the laser device is cutting or welding, the worker can unload and clamp at another station. However, this method is only suitable for the production rhythm of cutting and welding and the disassembly and clamping speed of the worker to be consistent or close. When the production rhythm of cutting and welding is much smaller than the disassembly and clamping speed of the worker, the laser device will still stop and wait, resulting in low production efficiency.
