AI Technical Summary

Technical Problem

In the process of coating the electrode assembly of lithium-ion power batteries, there are problems such as electrode or separator position displacement, complex coating structure, high cost and electrode misalignment. Traditional design makes it difficult to achieve automatic coating of the four sides of the electrode assembly.

Method used

An integrated rotary coating platform is used, combined with automatic electrode pressing and a suspended support structure. The double-plate side-push coating method is used to achieve simultaneous automatic coating of the sides and top and bottom of the electrode assembly. The adhesive paper is vertically adsorbed, and the hot pressing and unloading processes are carried out simultaneously through a dual-channel design.

Benefits of technology

The coating structure has been simplified, production costs have been reduced, coating efficiency has been improved, and automatic coating of the sides and top and bottom of the electrode assembly has been achieved, increasing production efficiency by 200%.

Abstract

This invention discloses a fully automatic electrode assembly coating hot press and its coating hot press process, including a machine base, a transfer mechanism, a coating device, and a hot press unloading device. The machine base includes two parallel, spaced-apart side sections and a connecting section. The coating device is mounted on the connecting section and includes a coating platform and a coating mechanism. The coating platform is mounted on the connecting section. The transfer mechanism spans above the coating platform. The coating mechanism includes at least two sets, arranged in pairs on both sides of the coating platform. The hot press unloading device includes two sets, respectively mounted on the two sides of the machine base. The hot press unloading device includes a unloading mechanism and a hot press mechanism. This invention achieves automatic switching between pressing the electrode and coating the electrode assembly side during coating, as well as suspended support for the electrode assembly, ensuring the stability of the electrode during coating, effectively simplifying the coating structure, reducing production costs, and achieving simultaneous automatic coating of the electrode assembly's side and top / bottom surfaces through a double-plate side-push coating method with upper and lower spacing.
