[0030] like Figure 1 and Figure 2As shown, the flip assembly includes a U-shaped connecting member 422 and a flip member 423 fixedly connected to the cylinder shaft 418 of the flip cylinder 416. The U-shaped connecting member 422 is rotatably connected to the fixing member 426 through the rotating shaft 428. Long oblique holes 427 are provided on both side plates of the U-shaped connecting member 422. Flip rods 425 are provided on both sides of the flip member 423.

The ends of the two flip rods 425 are respectively assembled in the first fixing block 420 and the second fixing block 424. When the flip cylinder 416 is working, the cylinder shaft 418 of the flip cylinder 416 drives the flip member 423 upward, so that the flip rod 423 slides along the long oblique hole 427, thereby driving the U-shaped connecting member 422 to flip 90° relative to the fixing member 426 with the rotating shaft 428 as the center.

[0031] like Figure 1 and Figure 2 As shown, the flip assembly is connected to the support assembly. Specifically, the support assembly includes a mounting plate 430, an L-shaped connecting plate 432 and a support beam 434 connected in sequence, the mounting plate 430 is fixedly connected to the U-shaped connecting member 422, and the support assembly can be flipped synchronously with the U-shaped connecting member 422.

[0032] like Figure 1 and Figure 3 As shown, the support assembly is slidably connected with a plurality of clamping mechanisms. Specifically, the clamping mechanism includes a clamping cylinder 440 and a clamping jaw 441. The clamping cylinder 440 is connected to the clamping jaw 441 and is used to drive the clamping jaw 441 to perform a gripping action. A guide rail 436 is provided at the bottom of the support beam 434, and a slider matching the guide rail 436 is provided at the top of the clamping cylinder 440. The slider is assembled on the guide rail 436 and can slide along the guide rail 436.

During the process, the cylinder axis 418 drives the flipping member 423 to move upward, and the flipping member 423 directly drives the U-shaped connecting member 422 to complete a 90° flip, thereby indirectly driving the battery cell 422 to complete a 90° flip, as shown in FIG.
