AI Technical Summary

Technical Problem

During the feeding process of the welding strip substrate, the inner ring of the material roll collapses, causing feeding jams, which in turn leads to abnormal wire breakage, reducing production efficiency and yield.

Method used

Design a limiting mechanism including a limiting unit that abuts against the inner circumferential surface of the weld strip base material roll to limit the height of the separation point between the pulled weld strip base material and the inner circumferential surface, thus preventing the inner ring from collapsing. A combination of spiral tubes or hollow straight tubes is used to adapt to different curvatures, and elastic elements are used for connection to adapt to different situations.

Benefits of technology

This effectively avoids the jamming problem during the feeding of the solder strip substrate, improving production efficiency and yield.

Abstract

This application discloses a limiting mechanism and a welding strip substrate feeding device for feeding welding strip substrate. The limiting mechanism includes at least one limiting unit. The limiting unit abuts against the separation point of the welding strip substrate on the inner circumferential surface of the welding strip base material roll to limit the height of the pulled-out welding strip substrate from the separation point on the inner circumferential surface of the welding strip base material roll, thereby preventing the welding strip substrate on the inner ring of the welding strip base material roll from slipping. This application effectively avoids the problem of wire jamming during welding strip substrate feeding caused by the collapse of the inner ring of the welding strip base material roll, effectively preventing abnormal wire breakage of the welding strip substrate, thereby improving production efficiency and yield.
