Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to a laser welding machine protective frame. Background Art

[0002] Laser welder is a highly efficient welding tool that uses a high-energy laser beam as a heat source to accurately fuse metal materials in a short time. This technology is widely used in the automotive, aerospace, precision engineering and other heavy industrial fields because it provides high-strength welding, precise control and fast processing capabilities. During the laser welding process, the laser beam can generate extremely high temperatures, accompanied by strong light and possible harmful radiation. Therefore, a protective frame must be used during operation to protect the operator and the surrounding environment from laser damage.

[0003] In actual use, traditional laser welding machine protective frames usually adopt a fixed or partially fixed design. Although this design can provide basic safety protection, it often lacks flexibility and adjustability. For example, the fixed protective frame cannot adjust the position or angle according to different welding tasks, which limits the flexibility of operation and may affect the welding quality. In addition, the traditional protective frame may be more troublesome during maintenance and cleaning, especially after continuous high-load operation, it is not easy to perform quick inspection and maintenance.
