[0002] In the field of intelligent manufacturing, bending of metal materials is a common process requirement, especially bending of light metals such as aluminum. Traditional bending equipment is usually large-scale specialized equipment with complex structure, large footprint, and insufficient flexibility, making it difficult to meet the needs of modern intelligent manufacturing for flexible and high-precision processing.

[0003] In existing technologies, industrial robots are widely used in various processing scenarios due to their high flexibility and programmability. However, ordinary robot bodies lack dedicated bending modules, making it difficult to directly perform high-precision metal bending tasks. Although some robots can achieve simple bending through additional mechanical devices, the following problems exist:

[0004] 1. The bending angle is limited and cannot meet diverse needs;

[0005] 2. The mechanical structure design is unreasonable and prone to interference with the workpiece;

[0006] 3. Lack of integrated pneumatic and electrical control, resulting in low automation.

[0007] Therefore, there is an urgent need for an opto-electro-mechanical bending device that is compact in structure, versatile in function, and easy to integrate with the robot body. Utility Model Content
