Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum plate processing, and particularly relates to a laser welding device for special-shaped aluminum single plates. Background Art

[0002] Aluminum plate is a plate material made of aluminum or aluminum alloy, or a plate-shaped aluminum product made from aluminum blanks through processes such as heating, rolling and straightening. The aluminum plates used in construction include single-layer aluminum plates, composite aluminum plates and other materials. Generally, single-layer aluminum plates are often referred to. Aluminum plates have been increasingly widely used due to their light weight and good conductivity. In recent years, single-layer aluminum plates have been more commonly used in aluminum curtain walls. During the processing of aluminum plates, aluminum plates often need to be welded.

[0003] The prior art patent announcement number CN217290856U is a spot welding device for welding aluminum plates to aluminum plates. The spot welding device for welding aluminum plates to aluminum plates is provided with a fixing mechanism and a spot welding assembly. The fixing mechanism facilitates the limiting and fixing of aluminum plates of different sizes, so that the spot welding device can weld aluminum plates of different sizes. This fixing method is relatively simple, has a good fixing effect, and is convenient for welding. The spot welding assembly can adjust the spot welding position of the aluminum plate according to demand, so as to better weld the aluminum plates to each other. This spot welding method is relatively simple, has a good spot welding effect, greatly improves the spot welding efficiency of the aluminum plate, and is convenient for better welding the aluminum plates. However, in actual use, there are still the following deficiencies: when welding the aluminum plate, welding smoke is generated. Welding smoke is a substance with a pungent odor and is toxic. Due to its small size, it will float in the air and is easily absorbed by the staff, causing harm to the health of the staff. The debris generated by welding is easily scattered on the surface of the workbench, requiring the staff to spend time cleaning it, increasing the work intensity of the workers.

[0004] Therefore, a laser welding device for special-shaped aluminum veneer is needed to solve the problems in the prior art that the toxic fumes generated by laser welding are easily inhaled by workers in large quantities, and the debris generated by welding is difficult to collect and clean.
