[0038] Refer to Figures 1 to 15 , an automated disassembly production line for a battery module in an embodiment of the present invention is used to disassemble the battery module 700 to obtain the battery blocks 740 inside. The automated disassembly production line for the battery module includes a feeding device 100, a top cover removing device 200, an electrode tab removing device 300, a shell cutting device 400, a shell removing device 500, and a splitting device 600.

[0039] The feeding device 100 is provided with a first position s1, a second position s2, a third position s3, a fourth position s4, a fifth position s5 and a sixth position s6. The feeding device 100 is used to receive the battery module 700 and to sequentially transfer the battery module 700 to the first position s1, the second position s2, the third position s3, the fourth position s4, the fifth position s5 and the sixth position s6. The top cover removing device 200 is arranged on one side of the feeding device 100. The top cover removing device 200 is used to position the battery module 700 at the first position s1 and to suck the top cover 710 of the battery module 700. The pole piece removing device 300 is arranged on one side of the feeding device 100. The pole piece removing device 300 is used to pick up the battery module 700 at the second position s2 and to remove the pole piece 720 of the battery module 700 and transfer it to the third position s3. The shell cutting device 400 is arranged on one side of the feeding device 100. The shell cutting device 400 is used to pick up the battery module 700 at the fourth position s4 and to position and cut the shell 730 of the battery module 700 and transfer it to the fifth position s5. After the shell 730 of the battery module 700 is cut, it is divided into two end heads 731 and two side plates 732. The shell removing device 500 is arranged at one end of the feeding device 100. The shell removing device 500 is used to pick up the battery module 700 at the sixth position s6 and to remove the end heads 731 and side plates 732 on the battery module 700. The splitting device 600 is arranged on one side of the shell removing device 500. The splitting device 600 is used to pick up the battery module 700 at the device 500 and to sequentially remove the battery blocks 740 on the battery module 700.

[0040] It can be understood that the pole piece removing device 300 is used to pick up the battery module 700 at the second position s2, and the battery module 700 is the battery module 700 after the top cover 710 is removed; the shell cutting device 400 is used to pick up the battery module 700 at the fourth position s4, and the battery module 700 is the battery module after the top cover 710 and the pole piece 720 are removed; the shell removing device 500 is used to pick up the battery module 700 at the sixth position s6, and the battery module 700 is the battery module 700 after the top cover 710 and the pole piece 720 are removed and cut; the splitting device 600 is used to pick up the battery module 700 at the shell removing device 500, and the battery module 700 is the battery module 700 after the top cover 710, the pole piece 720, the end heads 731 and the side plates 732 are removed.

[0041] It can be understood that after the shell 730 is cut by the shell cutting device 400, due to the adhesion effect, the cut end heads 731 and side plates 732 are still adhered to the battery block 740.

[0042] With the above structure, the feeding device 100, the top cover removing device 200, the pole piece removing device 300, the shell cutting device 400, the shell removing device 500 and the splitting device 600 cooperate with each other to be able to disassemble the battery module 700 to obtain the battery blocks 740 inside it.
