By arranging a plurality of shifting blocks 65 at fixed intervals on the shifting platform 64, the lithium battery 10 can be shifted along the feeding path and the lithium battery 10 can be automatically transported.

[0028] Preferably, the distance between two adjacent shifting blocks 65 is equal to the width of the lithium battery 10 .

[0029] Specifically, the material-shifting mechanism 6 also includes: a third telescopic component 66, horizontally arranged at one end of the shifting platform 64; a discharging block 67, arranged on the piston rod of the third telescopic component 66 parallel to the material-shifting block 65; and the lithium battery 10 is pushed toward the clamping component 8 through the third telescopic component 66.

[0042] During specific operation, after the conveyor belt 91 conveys the lithium battery 10 to the designated position, the conveyor belt 91 stops moving, the sixth telescopic component 97 and the fifth telescopic component 92 are started, and one end of the lithium battery 10 is abutted by the abutment head 95; the piston rod of the fifth telescopic rod is extended to drive the first detection head 931 and the second detection head 932 to be respectively inserted into the positive electrode head and the negative electrode head of the lithium battery 10, and the current sensor 94 is connected to the lithium battery 10, so as to form a closed loop between the lithium battery 10 and the current sensor 94; it can be understood that the current in the circuit flows from the positive electrode to the negative electrode. In the present invention, the current direction in the closed loop can be detected by the current sensor 94, so as to know the placement direction of the positive electrode head and the negative electrode head of the battery pack.

[0043] Subsequently, the telescopic rods of the sixth telescopic component 97 and the fifth telescopic component 92 are retracted to discharge the lithium battery 10; the piston rods of the sixth telescopic component 97 and the seventh telescopic component 98 corresponding to the positive electrode head of the battery pack are started to extend, driving the abutment head 95 and the sleeve 96 to clamp the lithium battery 10 along both ends of the positive electrode head; the drive motor 102 is started again to drive the lifting plate 100 to rise, so as to lift the lithium battery 10 from the conveyor belt 91; under the action of the lithium battery 10's own gravity, the lithium battery 10 rotates around the central axis of the positive electrode head, and the negative electrode head of the lithium battery 10 flips to the bottom of the positive electrode head; the drive motor 102 is reversed, driving the lifting plate 100 to descend, and the conveyor belt 91 also moves again, and one side of the lithium battery 10 contacts the conveyor belt 91 again until it is laid flat on the conveyor belt 91 again.

[0044] By using the present invention, lithium batteries 10 placed in different orientations can be turned over one by one and placed in the same orientation, so that a subsequent six-axis robot can grab the lithium battery 10 and place it on the storage part 11, ensuring that the liquid injection port of the lithium battery 10 is placed toward the plug of the liquid extraction mechanism 4.

[0045] It is worth mentioning that in order to ensure the accurate positioning of the lithium battery 10 by the flipping mechanism and the six-axis industrial robot, a number of photoelectric sensors and industrial cameras can be installed on both sides of the conveyor belt 91 to assist in positioning the lithium battery 10 .

[0046] In this embodiment, the detection assembly is also installed on the lifting plate 100 , and the first detection head 931 and the second detection head 932 pass through two sleeves 96 respectively and can slide inside the sleeves 96 .

[0047] It is worth mentioning that the telescopic component used in the present invention can be a cylinder, an electric telescopic rod or a hydraulic cylinder.
