AI Technical Summary
The existing single-cylinder telescopic mechanism cannot effectively raise the height of the light-blocking curtain when space is limited, which affects the loading and unloading operations of the robotic arm.
The system employs a dual-cylinder simultaneous telescopic mechanism. Through the coordinated operation of the first and second cylinders, the light-blocking curtain can be raised multiple times within a limited space, thereby increasing the lifting height of the light-blocking curtain.
By significantly increasing the height of the light-shielding curtain within a limited space, the robot arm can smoothly perform loading and unloading operations, effectively preventing welding arc light leakage from harming workers' eyes.
