AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

This utility model relates to a rotary arm assembly and a column robot with reduced end-effector droop. The rotary arm assembly includes a connecting arm and a first rotary drive component installed at the end of the connecting arm. The end of the connecting arm has a thickened portion in the section where the first rotary drive component is installed, increasing the thickness of the connecting arm body. The column robot includes at least one rotary arm assembly, a lifting assembly, and a material handling assembly. This utility model balances the relationship between structural strength and self-weight by thickening the stress concentration area while maintaining the original thickness in the non-stress concentration areas, thereby reducing the degree of end-effector droop of the rotary arm assembly, ensuring good levelness of the connecting arm, and improving motion accuracy. The column robot operates smoothly, has a wide range of movement, and achieves automated operation.
