The support rod 133 includes a screw 136 having an external thread, a fixing nut 134 fixedly installed on the table 110, and a rotating nut 135 rotatably coupled to the fixing nut 134. The fixing nut 134 and the rotating nut 135 include internal threads engaged with the external threads of the lead screw 136, and the lead screw 136 is disposed on the fixing nut 134 and the rotating nut 135 and penetrates the table 110. The height of the screw rod 136 in the vertical direction can be adjusted by rotating the rotating nut 135, the top of the screw rod 136 is connected with the support frame 131, the support frame 131 bears the battery to be disassembled, and the position of the shell of the battery to be disassembled cut by the cutting mechanism 150 can be adjusted by adjusting the height of the screw rod 136 in the vertical direction, so as to adapt to the disassembling requirements of batteries of different models and specifications.

The supporting frame 131 comprises a clamping device 137 for carrying and fixing the battery to be disassembled, wherein the length and the width of the clamping device 137 are adjustable.

The height of the supporting frame 131 is lower than that of the battery to be disassembled, so that the shell of the battery to be disassembled can be higher than the supporting frame 131 and can be directly cut by the cutting mechanism 150; the length of the support frame 131 is smaller than that of the battery to be disassembled, so that the bottom of the battery to be disassembled is partially arranged outside the support frame 131, and a drilling mechanism can drill holes at the bottom of the battery to be disassembled.

Fig. 3 is a schematic structural view of the support frame in some embodiments of the present disclosure, and fig. 4 is a side view of the support frame in some embodiments of the present disclosure. As can be seen from fig. 3 and 4, the clamping device 137 is a retractable spring mounted at the bottom of the supporting frame 131, and the length of the supporting frame 131 in the width direction can be adjusted by stretching outward to adapt to batteries with different specifications. When the battery to be disassembled is mounted on the supporting frame 131, and the clamping device 137 applies a force to the battery to be disassembled, so that the battery mounted in the supporting frame 131 can be firmly fixed, and the battery will not be displaced when the cutting mechanism 150 cuts the battery case to be disassembled.

The supporting frame 131 is rotatably connected to the supporting rod 133, and the connecting component is a nut fixed at the bottom of the supporting frame 131 and corresponding to the screw rod 136.

The drilling mechanism 170 is operative to form an opening in the bottom of the cell to be disassembled. Too small a diameter of the opening hole may result in too slow a collection speed of the electrolyte of the battery to be disassembled, and too large a diameter of the opening hole may result in the electrolyte being spilled in the process of collecting the electrolyte. Experience with production practice has shown that the diameter of the openings is typically 3 to 5 mm.

The battery disassembling apparatus 100 shown in fig. 1 further includes an extraction mechanism 190, which can close the opening connected to the battery to be disassembled and is configured to extract the electrolyte of the battery to be disassembled through the opening.

The extraction mechanism 190 can collect the electrolyte of the battery before the battery is disassembled, so that the battery is more safe to disassemble, and meanwhile, resources are recycled.

The liquid suction nozzle 191 is a sucker with a hollow tube at one end, and can be connected to the opening of the battery to be disassembled in a sealing mode, and the diameter of the liquid suction nozzle 191 is larger than that of the opening, so that electrolyte is prevented from being scattered when flowing to the liquid suction nozzle 191 from the opening. And the liquid suction nozzle 191 is connected with the opening in a sealing way, so that air can be prevented from entering the extraction mechanism 190 from the liquid suction nozzle 191, the negative pressure is reduced, and the speed of extracting the electrolyte is reduced.

The storage device 193 can be freely detached from the pipeline, and the electrolyte stored in the storage device 193 is transferred to other areas. The first connecting port is located at the top of the storage device 193 or at a position, close to the top, of the side wall of the storage device 193, the first connecting port is prevented from being too low in position, when electrolyte stored in the storage device 193 reaches the position of the connecting port, the electrolyte cuts off air between the power device 195 and the liquid suction nozzle 191, the liquid suction nozzle 191 loses negative pressure and cannot continue to suck liquid, the electrolyte capable of being stored in the storage device 193 can only reach the position of the first connecting port, and the storage capacity of the storage device 193 is limited.

The storage device 193 includes a transparent portion 194, the transparent portion 194 is disposed on a sidewall surface of the storage device 193, and the transparent portion 194 may be transparent glass or plastic. The amount of electrolyte stored in the storage device 193 can be observed through the transparent portion 194 so that the electrolyte can be transferred to other storage areas before the storage capacity limit is reached without affecting the normal operation of the extraction mechanism 190.

The power device 195 is a vacuum pump capable of generating negative pressure by pumping air, and is connected to the storage device 193 through a pipe. The conduit is removably connected at a second connection port of the storage device 193, such as by a mating threaded tubular connection, a bayonet-type tubular connection. The second connection port is positioned at the top or the position of the side wall of the storage device 193 which is closer to the top, so that the position of the second connection port is prevented from being too low, when the electrolyte stored in the storage device 193 reaches the position of the second connection port, the power device 195 sucks the electrolyte, the power device 195 is possibly damaged, and the storage capacity of the storage device 193 is limited at the position of the second connection port.
