Round corner heating mechanism for lithium batteries

Abstract

The invention provides a round corner heating mechanism for lithium batteries, which includes a bottom plate and a digital display regulating instrument. A vertical column is arranged on the bottom plate and a support plate is arranged on the vertical column. A battery cell adjustment device and a heating device are arranged on the support plate. The heating device includes a guiding piece in which a guiding trough is located. A heating rod is arranged in the guiding trough. A pulling rod is arranged on the heating device and is connected to an air cylinder through a pulling handle. In the mechanism, the air cylinder drives the pulling rod and the heating rod, wherein the lithium battery is arranged in the battery cell adjustment device, and corners, which need to be processed, are contacted with heating ports, and the heating rod rubs a sharp corner away during sliding. The mechanism can ensure that the radian of the processed round corners on the battery cell are equal and effectively avoids a hidden risk of short circuit in the battery cell. The mechanism is simple and is easy to operate and greatly improves efficiency and quality of lithium battery processing.

Description

technical field [0001] The invention relates to the field of lithium battery production, in particular to a fillet heating mechanism for lithium batteries.
