AI Technical Summary
In existing technologies, when handling large-size photovoltaic modules, the support arms tend to sag, resulting in insufficient load-bearing capacity and a large space occupation, which affects the operational stability and accuracy of the equipment.
Design a rotating arm assembly that balances structural strength and self-weight by thickening the stress concentration area while maintaining the original thickness in the non-stress concentration area, combined with a rounded rectangular structure, reduces the end-effector droop, and improves motion accuracy through multi-axis movable joints and zero-point positioning mechanism.
It effectively reduces the drooping of the rotating arm assembly end, improves motion accuracy, enables the column robot to operate smoothly and move over a wide range in small spaces, and achieves work automation.
