AI Technical Summary

⚠Technical Problem

Existing electromagnetic induction heating equipment is difficult to effectively heat the inside of the battery cell, resulting in long heating times and uneven heating.

⚗Method used

A split-type hot pressing device for battery cells is adopted. A closed magnetic conductive path is formed through a magnetic conductive device. The surface and interior of the battery cell are directly heated by the principle of electromagnetic induction. The heating component and the pressing component are set separately, which simplifies the structure and enhances the magnetic field penetration capability.

🎯Benefits of technology

It achieves uniform heating of the battery cells, shortens heating time, improves heating efficiency, adapts to battery cells of different thicknesses, and simplifies the equipment structure.

Abstract

The application discloses a split type battery cell hot-pressing equipment, which comprises a heating assembly, a pressing assembly and a conveying assembly. The heating assembly comprises a magnetic conducting device and a coil. The magnetic conducting device can form a closed magnetic conducting path. The magnetic conducting device has a first end portion and a second end portion. The first end portion and the second end portion are oppositely and spacedly arranged to form a heating space between the first end portion and the second end portion for heating the battery cell. The coil is connected to the magnetic conducting device. The pressing assembly comprises a first pressing member, a second pressing member and a first driving device. The first pressing member is used for bearing the battery cell. The second pressing member is oppositely arranged with the first pressing member and can be driven by the first driving device to relatively approach or move away. The conveying assembly is used for conveying the battery cell heated by the heating assembly to the pressing assembly for pressing. The heating assembly is heated based on the electromagnetic induction principle. The heating assembly is provided with the magnetic conducting device. The magnetic conducting device can increase the penetration ability of the magnetic field, thereby directly heating the surface layer and the interior of the battery cell to adapt to the heating of the battery cell.
