The carrier 110 is provided with a bearing surface 111 for bearing the pole piece, and the carrier 110 is further provided with a fitting hole 113 in a penetrating manner, an extending direction of the fitting hole 113 is perpendicular to the bearing surface, in this embodiment, an end opening of the fitting hole 113 is opened on the bearing surface 111. The first rotating shaft 170 passes through the matching hole 113, and the pressing piece 130 is disposed on the corresponding first rotating shaft 170 on the side where the bearing surface 111 is located.

In this embodiment, the bearing surface 111 is convexly provided with a plurality of limiting columns, and the plurality of limiting columns and the bearing surface together form a limiting space for accommodating the pole piece to limit the pole piece.

The pressing piece 130 is spirally wound on the first rotating shaft 170, and the first driving member 150 is connected to the first rotating shaft 170 and is used for driving the first rotating shaft 170 to rotate towards the first direction, so that the pressing piece 130 presses the pole piece towards the stage 110. First direction and the winding of pressing piece 130 on first pivot 170 are established the direction unanimously, when pressing piece 130 around locating first pivot 170 along the clockwise, first driving piece 150 drives first pivot 170 and rotates towards the clockwise and can realize holding the pressure of pole piece, when pressing piece 130 around locating first pivot 170 along the counter-clockwise, first driving piece 150 drives first pivot 170 and rotates towards the counter-clockwise and can realize holding the pressure of pole piece. In this embodiment, the pressing piece 130 is wound on the first rotating shaft 170 along a clockwise direction, and the first direction is a clockwise direction.

In the process that the pressing piece 130 rotates clockwise along with the first rotating shaft 170, a certain position on the bearing surface 111 corresponding to the pressing piece 130 gradually approaches to the pressing piece 130 in a direction perpendicular to the bearing surface 111 until the pressing piece 130 completely passes through the position, and the steps are sequentially circulated to realize the circular pressing of the pole piece loaded on the position. The tabletting efficiency is higher, and the preparation rate of the battery cell can be improved.

In this embodiment, the pressing piece 130 is rectangular, and one side thereof is connected to the first rotating shaft 170. The rectangle is an approximate rectangle, and the range defined by the vertical projection of the pressing and holding piece 130 on the bearing surface 111 is not closed in the circumferential direction, that is, the head and the tail ends of the pressing and holding piece 130 wound on the first rotating shaft 170 are not overlapped. When the end of the pressure-holding piece 130 far from the bearing surface 111 enters the area in the vertical direction of the new pole piece again, the pressure-holding is performed again.

In this embodiment, the first rotating shaft 170 is provided with a circular truncated cone 171 in a radial protruding manner, and the pressing piece 130 is spirally wound on a side wall of the circular truncated cone 171.

It is considered that the thicker the pole pieces stacked on the carrying surface 111 as the pressing process proceeds, the pressing of the pressing piece 130 is affected. In this embodiment, the carrier 110 and the first rotating shaft 170 are in a screw-slider fitting manner, that is, the first rotating shaft 170 is a screw, a slider is disposed on a side wall of the fitting hole 113 of the carrier 110, and the carrier 110 is fitted with the first rotating shaft 170 through the slider. To ensure that the carrier 110 can gradually move away from the pressing piece 130 as the first rotating shaft 170 rotates toward the first direction during the pressing process, so as to increase the height of the space between the bearing surface 111 and the pressing piece 130, the spiral direction of the thread groove on the first rotating shaft 170 is the first direction, i.e. the spiral direction of the thread groove on the first rotating shaft 170 is clockwise in this embodiment.

In this embodiment, the third driving element 195 drives the second rotating shaft 191 to rotate, so as to drive the pressing wheel 193 to rotate, and the pressing wheel 193 rolls to press the pressed side of the pole piece, so that the pressed side is lower than the height of the pressing piece 130 from the farthest end of the bearing surface 111, thereby ensuring that the pressing piece 130 can press and hold the pole piece. In this embodiment, the extension directions of the second rotating shaft 191 and the first rotating shaft 170 are perpendicular to each other. In practical applications, the vertical height of the pressing wheel 193 from the bearing surface 111 is matched with the specific height of the holding piece 130.
