[0018] Specific application examples of the utility model:

[0019] The pressurizing component can be made of a hydraulic cylinder. The pressurizing component drives the second pressing plate to move toward the first pressing plate to press the battery cell arranged on the first pressing plate. After the pressing is completed, the separation component arranged on the first pressing plate lifts the battery cell from the first pressing plate to separate the battery cell from the first pressing plate. The first telescopic component can be made of an electric telescopic rod. The first telescopic component drives the top plate to extend from the slot provided on the first pressing plate to lift the battery cell. The abutment plate provided on the side wall of the top plate abuts and matches with the limiting groove provided in the slot, so that when the first pressing plate and the second pressing plate press the battery cell, the top plate is supported by the abutment and matching of the limiting plate and the limiting groove. Avoid the first telescopic component from being damaged by excessive force during pressing. Multiple sets of slides are slidably connected with the through grooves provided on the upper side of the top plate. The sliding of the slides in the through grooves facilitates the movement of the battery cell located on the top plate, which is beneficial to loading and unloading the battery cell. The bottom wall of the slide plate and the through groove are slidably abutted against each other, and the driving device is arranged on the side wall of the slide plate and the through groove, which is conducive to avoiding pressure damage to the driving device during lamination. The first driving component can be made of a driving motor. The first driving component drives the rack to move through the gear. Anti-sticking paper can be arranged on the second pressing plate to avoid mutual adhesion with the battery core. The anti-sticking paper is fixed on the second pressing plate by arranging an adsorption component on the second pressing plate. The air in the vacuum chamber is extracted by a vacuum pump, and the gas enters the vacuum chamber through the adsorption hole, so that the anti-sticking paper is fixed on the second pressing plate. A pressing plate is hinged on the edge of the second pressing plate, and the anti-sticking paper can be clamped and fixed by matching the pressing plate with the second pressing plate. The card block and the card slot are mutually clamped and matched, and the pressing plate is fixed on the second pressing plate away from one end of the hinge shaft. A slot that matches the pressing plate can be opened on the first pressing plate to ensure that the first pressing plate and the second pressing plate can match each other.
