AI Technical Summary

Technical Problem

During the welding process of the outer armrest frame of the car seat, the inaccurate positioning of the slender flexible armrest wire leads to inaccurate weld point positions, affecting dimensional accuracy and welding strength. At the same time, the transfer between processes increases errors and reduces efficiency.

Method used

A step-by-step welding device is adopted, which integrates step-by-step positioning and floating deformation compensation. The floating support block applies an upward micro-movement support force below the steel wire to counteract the deformation during the clamping process and achieve dynamic precision control.

Benefits of technology

It improves welding accuracy and efficiency, reduces the time for transfer and reclamping between processes, eliminates positioning errors introduced by clamping actions, and enhances production efficiency and equipment integration.
