[0051] The aluminum shell battery side cutting mechanism 2 comprises a pneumatic cylinder 201, a side cutting mounting frame 202, a side cutting knife fixing plate 203 and a side cutting knife 204.

[0052] The transverse cutting mechanism 3 comprises a servo motor 301, a motor fixing plate 302, a lead screw 303, a linear slide rail 304, a disassembling knife fixing plate 305 and a disassembling knife 306.​​​​

[0053] The carrying module mechanism 4 includes a battery fixing clamp 401, a battery pressing plate 402, a clamp sliding seat 403, a module mounting plate 404, a servo module 405, a linear guide rail 406, and an electromagnetic lock 407.

[0054] The electrolyte collecting mechanism 5 includes a push air cylinder 501, a mounting plate 502, a mounting plate foot 503, an electrolyte collecting box 504, and a liquid discharge switch 505.

[0055] The aluminum shell battery side cutting mechanism 2 includes a cylinder 201, which is used as the main power for the side cutting mechanism. The cylinder 201 is installed at the top end of the side cutting mounting frame 202. The piston rod end of the cylinder 201 is equipped with a side cutting knife fixing plate 203 for installing two side cutting knives 204 on both sides. The knife edge top of the side cutting knife 204 is equipped with a blade. When the cylinder 201 moves, it drives the side cutting knife 204 to press down and cut the two side surfaces of the aluminum shell battery downward.

[0056] The transverse cutting mechanism 3 includes a servo motor 301 for providing power for the up and down adjustment of the entire mechanism, which is installed on the motor fixing plate 302 at the top of the structure. The motor fixing plate 302 is installed below the lead screw 303, which is rotated by the servo motor 301 to drive the lead screw 303 to rotate and provide upward and downward movement for the entire disassembly knife 306. Two linear sliding rails 304 are installed in parallel with the lead screw 303 to assist the movement of the lead screw 303 without being deformed under stress. The disassembly knife fixing plate 305 is also installed on the lead screw 303 and the linear sliding rail 304 to fix the disassembly knife 306.

[0057] The disassembling knife 306 includes a direct current motor 3061 for providing impact power to the disassembling knife. Fixed with the direct current motor 3061 is a shell 3062 composed of four plates for sealing the rotating part of the motor. Connected with the shaft of the direct current motor 3061 is a coupling 3063 for transmitting power and correcting the deviation of the installation shaft. Connected with the other end of the coupling 3063 is a deflection disc 3064. The coupling 3063 belongs to standard hardware fittings, and has hole positions for fixing the shaft at both ends. The shaft of the deflection disc 3064 is inserted into the coupling. There is a support plate in the shell 3062 for matching with the shaft. The deflection disc is connected with the coupling by locking screws.

One end of the spring is abutted against the impact step of the impact needle 3065, and the other end is abutted against the shell. The elastic force of the spring makes the spherical surface of the impact needle always tightly abut against the disc surface of the deflection disc. With the rotation of the deflection disc, the impact needle will cyclically and reciprocally slide, converting the rotary force into the reciprocating sliding force. It is ensured that the spherical surface of one end of the impact needle always keeps in contact with the deflection disc 3064 in the sliding state. The knife handle fixing seat 3066 is used for installing the disassembling knife handle 3068. There is a special-shaped hole in the knife handle fixing seat 3066, which forms a clearance sliding fit with the disassembling knife handle 3068. The knife rod of the disassembling knife handle 3068 is originally cylindrical. In order to limit the rotation of the cylinder, two planes are symmetrically processed on both sides of the cylindrical surface, so that the disassembling knife handle 3068 can only slide in the knife handle fixing seat 3066. One end of the disassembling knife handle 3068 is provided with a threaded impact step 3067 for receiving the reciprocating knocking of the impact needle 3065. At the same time, it also plays a limiting role. The disassembling blade 3069 is used for applying impact vibration force to the blade, so that the aluminum shell is cut open when disassembling the aluminum shell, and the waste is rolled on both sides of the cut opening, and will not fall into the electrolyte.

[0058] The carrying module mechanism 4 includes a battery fixing clamp 401 for fixing the aluminum shell battery and collecting the electrolyte flowing out when the aluminum shell battery is cut open. The battery pressing plate 402 is provided with knob screws on both sides, which can quickly fix the battery in the battery fixing clamp 401. The clamp sliding seat 403 is in sliding fit with the battery fixing clamp 401. The electromagnetic lock 407 is installed on the right side of the clamp sliding seat 403. The lock core is a cylinder with a diameter of 8 mm, which is inserted into the circular hole on the right side of the battery fixing clamp 401. The function of the electromagnetic lock 407 is to limit the sliding of the battery fixing clamp 401 in the clamp sliding seat 403. The electromagnetic lock 407 is energized to be unlocked. After the disassembly is completed, the battery fixing clamp 401 will be pushed out. The servo module 405 is the power for the left and right direction movement of the whole mechanism, which is used to drive the whole mechanism to move on the module. The linear guide rail 406 is installed in parallel with the servo module 405. The main purpose of the linear guide rail 406 is to bear the downward gravity, and to assist the linear guide rail 406 to drive the mechanism to move left and right.
