The lower part of the push plate assembly 306 is installed on the upper part of the moving block 307. The middle part of the moving block 307 is slidably connected to the outer periphery of the limiting groove 305. The lower part of the moving block 307 is rotatably connected to one end of the connecting rod 303, and the other end of the connecting rod 303 is rotatably connected to one end of the cross 302.

The push plate assembly 306 includes a vertical plate 3061, a pressure sensor 3062 and a push plate 3063. The middle part of the push plate 3063 is installed at one end of the pressure sensor 3062, and the other end of the push plate 3063 is installed in the middle part of the vertical plate 3061. The lower part of the vertical plate 3061 is installed on the upper part of the moving block 307, and a rubber pad 3064 is provided on the side of the push plate 3063 away from the vertical plate 3061.

[0023] Specifically, the servo motor 301 is driven so that the cross 302 drives the connecting rod 303 to move, and then the moving block 307 drives the push plate assembly 306 to move closer to each other, so that the battery cell is clamped in the center by the push plate assembly 306 to ensure that the battery cell is located in the middle of the platform 1, and the pressure sensor 3062 and the rubber pad 3064 are used to prevent excessive force from causing damage to the battery cell.

When the upper part of the rubber ring 4045 is completely blocked by the battery cell, the cavity between the battery cell and the piston 4043 is negative pressure, so that the battery cell is adsorbed on the upper part of the rubber ring 4045, and then the servo motor 301 is driven so that the moving block 307 drives the push plate assembly 306 away from the battery cell to prevent the battery cell from being displaced during cutting, thereby ensuring the cutting accuracy and eliminating the influence of external force on cutting.
