A support-stable split main drive mechanism

By supporting a stable split-type main drive mechanism and adjusting the positions of the large-diameter roller and the electrode ear roller, the problem of welding instability caused by the inconsistent thickness of the composite current collector body and the electrode ear is solved, thereby improving the stability of the welding process and the production yield.

AI Technical Summary

Technical Problem

The inconsistent thickness of the composite current collector body and the tab leads to inconsistent travel speeds in the welding machine. Over time, the accumulated errors cause defects such as wrinkles and tears to appear in the composite current collector.

Method used

A stable split-type main drive mechanism is adopted. The positions of the large roller and the electrode ear roller are adjusted by the first and second lifting drive components respectively, ensuring that the composite current collector body and the electrode ear are clamped at the same time, thus maintaining the stability of the welding machine.

Benefits of technology

This reduces the occurrence of defects such as wrinkles and tears in composite current collectors during the welding process, thereby improving production yield.

Abstract

The application discloses a stable supporting split type main driving mechanism, which comprises a rack, the rack comprises a fixed frame, a movable frame and a first lifting driving element, a traction roller is rotationally connected to the fixed frame, a rotation driving element provided on the fixed frame is transmissionally connected to the traction roller, a rubber coating roller is rotationally connected to the movable frame, the rubber coating roller comprises a mandrel, a large roller, a tab seat and a tab roller, a second lifting driving element connected to the tab seat is arranged on the fixed frame, the first lifting driving element is used for adjusting the distance between the large roller and the traction roller, and the second lifting driving element is used for adjusting the distance between the tab roller and the traction roller. The first lifting driving element and the second lifting driving element are respectively used for adjusting the positions of the large roller and the tab roller, so that the large roller and the tab roller can simultaneously and stably support the composite current collector body and the tab, the stability of the composite current collector in the welding machine is maintained, the occurrence of adverse conditions such as wrinkles and tearing is reduced, and the production yield is improved.
