When it rotates to the side of the diaphragm, the first telescopic plate 123d protrudes outward along the first guide rod 123c to stack the positive electrode sheet on the side of the diaphragm. The second suction mechanism 124 includes a second rotating power 124a for providing power, a second turntable 124b connected to the output end of the second rotating power 124a, and a second guide rod 124c installed on the end of the second turntable 124b away from the second rotating power 124a , the second telescopic plate 124d slidably arranged on the second guide rod 124c, the second sucker 124e installed on the free end of the second telescopic plate 124d; after the second sucker 124e sucks the negative plate, the second rotating power 124a drives the second The suction cup 124e rotates to drive the negative electrode sheet to rotate. When it rotates to circumscribe the other side of the diaphragm, the second telescopic plate 124d protrudes outward along the second guide rod 124c to stack the negative electrode sheet on one side of the diaphragm. Through the rotation and stretching of the first suction cup 123e and the second suction cup 124e, it is ensured that the positive and negative plates can be accurately circumscribed to both sides of the diaphragm, so that they can be accurately stacked on both sides of the diaphragm, further improving the lamination accuracy and lamination quality .

As shown in FIG. 11 , it is a perspective view of the winding station of the present invention.

On the one hand, several lamination devices 120 are provided on the turntable 110 of the lamination station 100 of the present invention. When one lamination device 120 completes the lamination of the preset number of layers, the turntable 110 rotates to make another lamination The device 120 arrives at the stacking station 100 for stacking, and the finished stacking device 120 rotates to the next station to carry out processes such as winding after stacking. Since a plurality of stacking devices 120 are provided, the stacking Processes such as winding and winding can be carried out at the same time, and the work efficiency is high. In the second aspect, in the lamination device 120, the lamination power mechanism 122 drives the lamination turntable 121 to alternately swing toward the first suction mechanism 123 and the second suction mechanism 124. Since the diaphragm passes through the center of the lamination turntable 121, the diaphragm also Swing together with the lamination turntable 121, when the diaphragm swings to contact with the positive electrode sheet sucked by the first suction mechanism 123, the positive electrode sheet is stacked on one side of the diaphragm, and when the diaphragm swings to contact with the negative electrode sheet sucked by the second suction mechanism 124 When in contact, the negative plate is stacked on the other side of the diaphragm and reciprocates accordingly. Compared with the traditional diaphragm reciprocating linear motion between the positive and negative plates, the diaphragm of the utility model reciprocates between the positive and negative plates, which takes less time. Lamination efficiency is high. In a third aspect, the first suction mechanism 123 and the second suction mechanism 124 are symmetrically arranged on both sides of the lamination turntable 121, and the swing trajectory of the lamination turntable 121 is the same as that of the first suction mechanism 123 and the second suction mechanism 124 respectively.

The cell lamination method comprises the following steps,

Feeding: the first loading station 200 carries out positive electrode sheet feeding, the second feeding station 300 carries out negative electrode sheet loading, the diaphragm feeding mechanism 125 releases the diaphragm, and the diaphragm passes through the center of the laminated rotary table 121;

Lamination: the lamination power mechanism 122 drives the lamination rotary table 121 to drive the diaphragm to swing to the side of the first suction mechanism 123; the first suction mechanism 123 absorbs the positive electrode sheet and drives the positive electrode sheet to rotate to the side of the diaphragm to circumscribe The positive plate is stacked on one side of the diaphragm; the stacked power mechanism 122 drives the stacked rotary table 121 to drive the diaphragm to swing to the side of the second suction mechanism 124; the second suction mechanism 124 sucks the negative plate and drives the negative plate to rotate to the point where it is away from the positive plate from the diaphragm One side is circumscribed, so that the negative electrode sheet is stacked on the side of the diaphragm away from the positive electrode sheet; the positive electrode sheet and the negative electrode sheet are stacked sequentially to a preset number of layers; after the lamination is completed, the turntable 110 rotating device (not shown in the figure ) driving the turntable 110 to rotate to drive the stacking device 120 to rotate to the winding station 400;

Winding: The clip assembly 440 moves to the laminated device 120 under the action of the first power assembly 450 to clamp the pole piece, and the second power assembly 460 drives the clip assembly 440 to rotate to wind the diaphragm outside the pole piece, continuous winding preset layers;

Shearing: After the winding is completed, the shearing station 500 cuts the diaphragm;

Stamping: After the shearing is completed, the first power assembly 450 drives the clip assembly 440 to drive the pole piece to move along the winding track 410 to the stamping station 600, and the stamping station 600 compresses the pole piece;

Wherein, the lamination power mechanism 122 drives the lamination turntable 121 to swing to the first suction mechanism 123 and the second suction mechanism 124 at an angle of 45°. When the swing angle is too large, the swing range of the lamination turntable 110 Large, time-consuming, and not conducive to improving the lamination efficiency. When the swing angle is too small, the swing range of the lamination turntable 121 is too small. Although it takes less time, the space under the diaphragm on the lamination turntable 121 is small, and the diaphragm is not easy to contact with the pole. The outer cutting of the sheet leads to low lamination accuracy. Experiments have proved that when the swing angle is 20°-60°, especially when the swing angle is 45°, the lamination efficiency and lamination accuracy are the best.
