Description

Technical field:

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a laser welding machine. Background technology:

[0002] Steel plates are often needed in the industrial manufacturing process, and the raw materials of steel plates are usually coils. In order to ensure the continuity of material feeding during the production process and avoid the machine tool working without load, it is usually necessary to weld the ends of two coils together. The traditional method is to add a welding mechanism on the transmission line of the steel plate. In order to ensure that the ends of the butted steel plates are flush, a cutting mechanism is also required to be added to the front end of the welding mechanism for leveling. This requires the steel plate to pass through the cutting mechanism and the welding mechanism in real time, which not only leads to the longitudinal extension of the production line, but also the steel transmission will cause wear on the cutting mechanism and the welding mechanism, reducing its Service life, such as: a steel plate butt joint machine with a Chinese patent authorization announcement number of CN2858172Y. In the solution disclosed in the patent, the cutting mechanism 4 and the welding mechanism 5 are located behind the alignment mechanism 3. The steel plate passes through the cutting mechanism 4 and the welding mechanism 5 from the end of the alignment mechanism 3 and enters the subsequent process. Since the cutting mechanism 4 and the welding mechanism 5 are only used when the steel plates are connected end to end, this structure will cause the steel plates to pass through the cutting mechanism 4 and the welding mechanism 5 during the transmission process, which may easily cause the parts in the cutting mechanism 4 and the welding mechanism 5 to wear too quickly, greatly reducing their service life.
