[0057] First, the flow tooling with 4 battery cells flows on the battery cell conveying device (such as a conveyor line) to the unloading station; the six-axis material picking robot moves to the top of the unloading station, grabs the battery cells from the transfer tooling and moves to the top of the battery cell pre-stacking device, and the six-axis material picking robot puts the battery cells into the battery cell receiving position; the material receiving mechanism 10 is lifted, and the battery cell clamping assembly 210 in the battery cell shaping mechanism 20 clamps the battery cells, and the robot then moves to the end plate unloading station, and the six-axis material picking robot clamps the end plate and transfers it to the end plate receiving position; the material receiving mechanism 10 of the battery cell pre-stacking table starts to shape the battery cells and the end plates after receiving the materials.

[0058] The end plate moves to the material receiving position through the feeding mechanism 40, the material receiving mechanism 10 descends, the end plate clamping assembly 810 in the end plate shaping mechanism 80 is released, the end plate spinning assembly 830 in the end plate shaping mechanism 80 presses the end plate to the shaping reference assembly 270 (such as a reference beam), the end plate clamping assembly 810 clamps the end plate, the material receiving mechanism 10 moves forward to the specified position, the end plate adsorption assembly 870 extends out to absorb the end plate, the end plate clamping assembly 810 is released, the centering mechanism 50 retreats, the end plate adsorption assembly 870 retracts, the oblique inserts on both sides guide the end plate, and the end plate reaches the specified position. The material receiving and transferring axis of the material receiving structure continues to move forward, and first shapes the No. 1 battery cell at the front. After moving forward to the specified position, the material receiving mechanism 10 descends, and the battery cell clamping assembly 210 in the battery cell shaping mechanism 20 is loosened. The battery cell spinning assembly 230 in the battery cell shaping mechanism 20 presses the battery cell so that the battery cell is attached to the battery cell reference position. The battery cell clamping assembly 210 clamps the battery cell, and the material receiving axis continues to move forward so that the end face of the battery cell is close to the adhesive surface of the end plate and the battery cell is adhered to the battery cell by tape. The battery cell clamping assembly 210 and the centering mechanism 50 are loosened, so that the claws of the clamping cylinder are out of the safe range of the battery cell; the No. 2 battery cell, the No. 3 battery cell and the No. 4 battery cell repeat the above actions to shape and stack the battery cells in turn; after completing all the above steps, all mechanisms exit; the material receiving mechanism 10 moves to the origin, and the pre-stacked battery cell group is grabbed by the six-axis material-taking robot to the stacking table for larger module formulation.

[0059] The present application also provides a battery cell pre-stacking device, such as Figure 7As shown, the pre-stack device for battery cells includes a battery cell pre-stack device and a battery cell conveying device (not shown). The battery cell conveying device can convey battery cells to a receiving position, and the receiving position is located above the receiving mechanism of the battery cell pre-stack device.

[0060] The division of each module in the above battery cell pre-stack device is only for illustrative purposes. In other embodiments, the battery cell pre-stack device can be divided into different modules as needed to complete all or part of the functions of the above battery cell pre-stack device.

[0061] For the battery cell pre-stack device and the battery cell pre-stack equipment provided in the above embodiments, when stacking battery cells during the production process, the receiving mechanism receives the battery cells. The battery cell shaping mechanism clamps and moves the battery cells conveyed by the receiving mechanism through the battery cell clamping assembly provided on the battery cell shaping base, and presses the battery cells after the battery cell clamping assembly releases them to the battery cell reference position through the battery cell spinning assembly also provided on the battery cell shaping base. Then, the battery cell clamping assembly clamps the battery cells located at the battery cell reference position and drives the end faces of the battery cells to abut against the adhesive surface of the end plate or the end faces of adjacent battery cells. Compared with the traditional method of repeatedly grouping using manual tooling, while ensuring the pre-stack accuracy between the end plate and the battery cells, and between the battery cells, it can also ensure the pre-stack efficiency between the end plate and the battery cells, and between the battery cells, thereby meeting the high-speed production and processing requirements of the workshop and the subsequent transfer and processing efficiency of the battery cells, and having important economic value and promotion and practical value.

[0062] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
