HOT-PRESSING DEVICE

Resumen de: EP4679545A1

Disclosed is a hot-pressing apparatus, which comprises a hot-pressing drive mechanism, a first hot-pressing mechanism, a second hot-pressing mechanism, a diaphragm clamping mechanism and a jacking mechanism. Before transferring the battery cell, the supporting assembly may be driven first to jack a part of the diaphragm, thus forming the transferring-supporting surface above the second hot-pressing plate. The jaw first places the battery cell on the transferring-supporting surface, the transferring-supporting surface may contact only a part of the battery cell to allow the jaw to be suspended, and once the jaw is released, it can be withdrawn. Next, the jacking mechanism withdraws to flatten the diaphragm, and the battery cell will be borne on the diaphragm steadily. As the hot-pressing drive mechanism drives the first hot-pressing plate and the second hot-pressing plate close to each other, the first hot-pressing plate may press the diaphragm and the battery cell borne on the diaphragm against the second hot-pressing plate. It is clear that in a process of transferring the battery cell to the second hot-pressing plate, the use of the diaphragm for transferring may prevent the battery cell from shaking or tilting, thus placing the battery cell steadily.
