And controlling the tool picking mechanism 12 to adsorb or clamp the tool, and synchronously enabling the first welding strip pressing mechanism 13 and the second welding strip pressing mechanism 14 to downwards penetrate out of the hollow area on the tool.
Then, the carrying assembly 10 is controlled to move perpendicular to the extending direction of the solder strip groups, so that the first end of the first solder strip group enters the first solder strip pressing mechanism 13, and the second end of the second solder strip group enters the second solder strip pressing mechanism 14.
And then, controlling the first solder strip pressing mechanism 13 and the second solder strip pressing mechanism 14 to respectively clamp the first end of the first solder strip group and the second end of the second solder strip group.
And finally, controlling the carrying assembly 10 to ascend and move to the position above the battery piece, and controlling the carrying assembly 10 to release the solder strip group and the tooling so as to stack the solder strip group and the tooling on the battery piece.
It can be seen that the carrying assembly 10 of the present invention realizes the simultaneous carrying of the tooling and the welding strip set by the cooperation of the tooling picking mechanism 12, the first welding strip pressing mechanism 13 and the second welding strip pressing mechanism 14, thereby greatly improving the carrying efficiency.
In addition, the first solder strip pressing mechanism 13 and the second solder strip pressing mechanism 14 of the carrying assembly 10 of the present invention clamp the solder strip by pressing, so that the solder strip is not easy to turn over.

Optionally, the first solder strip pressing mechanism 13 and the second solder strip pressing mechanism 14 in the present invention have the same structure, and each includes a fixed pressing plate 131, a movable pressing plate 133, and a movable pressing plate driving mechanism 139, where:
the fixed pressing plate 131 is detachably mounted on the mounting bracket 11, a plurality of horizontal pressure-bearing tongues 132 are arranged at the lower end of the fixed pressing plate 131 side by side along a second horizontal direction (such as the Y-axis direction in the figure) perpendicular to the first horizontal direction, and the pressure-bearing tongues 132 protrude inwards relative to the fixed pressing plate 131.
The lower end of the movable pressing plate 133 is provided with a plurality of pressing rods 134 in parallel in the second horizontal direction, the pressing rods 134 are in one-to-one correspondence with the pressure-bearing tongue plates 132, each pressing rod 134 and the corresponding pressure-bearing tongue plate 132 form a welding strip pressing assembly, and each welding strip pressing assembly is used for pressing one welding strip in the welding strip group.
