Description

[0002] In the field of aluminum product processing, laser cutting is a commonly used processing method. However, there are some problems in the processing of existing aluminum product laser cutting equipment. Traditional cutting equipment mostly uses a clamping method to fix aluminum plates, which easily causes the aluminum plates to deform and be scratched due to clamping force, affecting product quality. Moreover, for aluminum plates of different sizes (length, width, thickness), existing equipment is often difficult to flexibly adapt, and it is necessary to frequently replace tooling or perform complex adjustments, reducing processing efficiency. In addition, during double-sided processing of aluminum plates, the flipping operation is relatively complex, and problems such as displacement and falling off of aluminum plates are likely to occur, affecting processing accuracy and stability.
