[0029] The battery sorting mechanism 10 further comprises a clamping assembly 600, which is fixedly connected to the power output end of the clamping lifting assembly 400, and the power output direction of the clamping lifting assembly 400 and the power output direction of the pushing assembly 500 form an included angle; the conveying area of the first conveying plate 100 is provided with a plurality of first battery placing positions 110, and the conveying area of the second conveying plate 200 is provided with a plurality of second battery placing positions 210; the clamping assembly 600 is used for clamping qualified batteries from the first battery placing positions 110 to the second battery placing positions 210.

[0031] In combination Figure 2 With Figure 3As shown in the drawings, in one embodiment, the clamping assembly 600 comprises at least two clamping members 610, each of which comprises a clamping cylinder 6110, a first clamping hand 6120 and a second clamping hand 6130, the clamping cylinder 6110 is fixedly installed on the support block 4210, and the power output end of the clamping cylinder 6110 is connected with the first clamping hand 6120 and the second clamping hand 6130 respectively to drive the first clamping hand 6120 and the second clamping hand 6130 to approach or move away from each other. It can be understood that by rotating the first clamping hand 6120 connected to one side of the clamping cylinder 6110, the clamping cylinder 6110 is driven to rotate the first clamping hand 6120 to approach the second clamping hand 6130, and by driving the clamping cylinder 6110 to rotate the second clamping hand 6130 to approach the first clamping hand 6120, the first clamping hand 6120 and the second clamping hand 6130 are rotated around their respective rotation points and gradually approach to finally clamp the battery; when the battery needs to be released, the clamping cylinder 6110 drives the first clamping hand 6120 and the second clamping hand 6130 to move away from each other.

[0032] As shown in the drawings, Figure 3 In one embodiment, the first clamping hand 6120 and the second clamping hand 6130 are provided with a clamping opening 6121, and the first clamping hand 6120 and the second clamping hand 6130 are respectively provided with a first limiting boss 6122 and a second limiting boss 6131, and the first limiting boss 6122 and the second limiting boss 6131 are arranged in the clamping opening 6121.

[0033] As shown in the drawings, Figure 2As shown, in one embodiment, the clamping and lifting assembly 400 includes a lifting driver 410 and a lifting block 420. The lifting driver 410 is mounted and fixed to the power output end of the pushing assembly 500. A sliding guide rail 4110 is provided on the side wall of the lifting driver 410. The lifting block 420 is slidably disposed on the sliding guide rail 4110. The drive shaft of the drive rod of the lifting driver 410 is connected to the lifting block 420 so that the lifting block 420 slides up and down. It is understood that a sliding guide rail 4110 is provided on the side wall of the lifting driver 410, and the lifting block 420 is slidably disposed on the sliding guide rail 4110, thereby enabling the lifting block 420 to slide up and down within the trajectory of the sliding guide rail 4110; when the drive rod of the lifting driver 410 extends upward, because the drive rod of the lifting driver 410 abuts against the lifting block 420, the lifting block 420 moves upward, and because the lifting block 420 is slidably disposed within the sliding guide rail 4110, the lifting block 420 can slide up and down along the trajectory of the sliding guide rail 4110.

[0034] like Figure 3 As shown, the lifting block 420 further includes a support block 4210 and a sliding block 4220. The sliding block 4220 is slidably disposed on the sliding guide rail 4110.

The clamping assembly 600 is installed at the end of the support block 4210. It is understood that the sliding block 4220 is set on the sliding guide rail 4110. Since the sliding block 4220 is connected to the drive shaft of the drive rod of the support block 4210 and the lifting driver 410 respectively, and since the clamping component 600 is installed at the end of the support block 4210, when the sliding block 4220 moves up and down on the sliding guide rail 4110, the support block 4210 moves up and down with the sliding block 4220. Since the bracket 620 abuts against the support block 4210, when the support block 4210 moves up and down, it will drive the bracket 620 to move up and down, thereby causing the clamping component 610 to move up and down to clamp the battery.
