Abstract

The invention relates to the technical field of battery cell processing, in particular to battery cell preheating and hot pressing equipment. According to the battery cell preheating hot-pressing equipment, the preheating clamping mechanism is adopted to preheat the battery cell, the battery cell is in contact with the preheating clamping piece of the preheating clamping mechanism, the preheating clamping piece has a heating function, the battery cell is preheated in a mode of being in contact with the battery cell, the preheating efficiency is higher, and compared with a mode of preheating the battery cell through heat radiation, the battery cell preheating hot-pressing efficiency is improved. The battery cell preheating efficiency is improved by adopting a mode of contacting with the battery cell, and the technical problem of low battery cell shaping efficiency caused by long required time and low battery cell preheating efficiency of an existing battery cell preheating mode is solved.

Description

technical field [0001] The present application relates to the technical field of cell processing, and in particular, to a cell preheating and hot pressing device. Background technique [0002] The descriptions in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Existing cells are generally formed by stacking an anode sheet, a separator and a cathode sheet in sequence and then winding, and hot-pressing shaping is required after winding. For example, a cell hot pressing machine disclosed in the Chinese Patent Application Publication No. CN114156524A can realize the simultaneous hot pressing of a plurality of cells. [0004] In actual production, due to the constant tension mode used in the winding process, the inner ring of the cell has a large tension. In the hot pressing process, the surface of the cell and the hot pressing plate are in contact with heat transfer. The temperature gradually decre...
