DETAILED DESCRIPTION
[0022] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive. Example
[0023] Please refer to the attached Figure 1 , 2 As shown in , 3 and 4, a battery disassembly and recovery device comprises a shell 1, a feed port 101 is provided on the top of the shell 1, and a discharge port 102 is provided on the side wall of the shell 1. A cutting mechanism 2 and a glue removal and washing mechanism 3 are provided in the shell 1. The cutting mechanism 2 includes a slide rail 201. The slide rail 201 is provided on the inner top wall of the shell 1. A sliding motor 202 is connected to the outer wall of one side of the slide rail 201. The output end of the sliding motor 202 is transmission-connected to a sliding screw 203. The end of the sliding screw 203 away from the sliding motor 202 is rotationally connected to the inner wall of the slide rail 201 through a first bearing seat 204. A connecting rod 205 is sleeved on the sliding screw 203. A cutting assembly 206 is provided on one side of the connecting rod 205. The cutting assembly 206 includes a cutting motor 207. The cutting motor 207 is provided on one side of the connecting rod 205. The output shaft of the cutting motor 207 is transmission-connected to a rotating rod 208. The end of the rotating rod 208 away from the cutting motor 207 is connected to a cutting knife 209. The cutting knife 209 is detachably connected to the rotating rod 208.
[0024] It should be noted that the slide rail 201, the sliding motor 202 and the sliding screw 203 in the cutting mechanism 2 cooperate to accurately control the position of the cutting assembly 206, ensuring that the cutting knife 209 accurately cuts off the top cover of the battery shell, thereby improving the precision and quality of the cutting. The cutting knife 209 is detachably connected to the rotating rod 208, which is convenient for replacing the cutting knife according to different cutting requirements, thereby increasing the flexibility and applicability of the device.
[0025] Please refer to the attached Figure 4 As shown, the glue removal and flushing mechanism 3 includes a flushing head 301, which is located on the inner wall of the shell 1. The flushing head 301 is connected to a solenoid valve 302, and one end of the solenoid valve 302 away from the flushing head is located on the outer wall of the shell 1. A waste liquid pool 303 is provided below the flushing head 301, and the waste liquid pool 303 can be slidably arranged in the shell 1.
[0026] It should be noted that the positive electrode material in the lithium iron phosphate battery is lithium iron phosphate, which is located on the aluminum foil current collector and adhered to the diaphragm on the inner wall of the battery shell through a polyacrylic acid (PAA) adhesive. The negative electrode material is graphite, which is located on the copper foil current collector and adhered to the diaphragm on the inner wall of the battery shell through an adhesive composed of styrene-butadiene rubber (SBR) and sodium carboxymethyl cellulose (CMC). Both adhesives are soluble in water. The degumming and flushing mechanism 3 is connected to a water pipe through the input end of the solenoid valve 302. After the output end of the solenoid valve 302 is connected to the flushing head 301, the flushing head 301 sprays water to flush the inside of the battery shell with the top cover cut off, which can dissolve part of the adhesive or remove some impurities, thereby weakening the bonding force between the positive and negative electrode materials and the battery shell. After the degumming and flushing mechanism 3 flushes the inside of the battery shell, the subsequent vibration step can more conveniently peel off the positive and negative electrode materials.
[0027] It should be noted that when the glue removal and flushing mechanism 3 flushes the inside of the battery shell with the top cover cut off, the electrolyte is flushed and collected into the waste liquid pool 303 located below the flushing head 301 to avoid the electrolyte remaining inside the battery shell and affecting the stripping of the positive and negative electrode materials. The waste liquid pool 303 can be slid out of the shell 1 to facilitate the collection and treatment of the waste liquid after flushing.
[0028] Please refer to the attached Figure 5 As shown, a rotating mechanism 4 is provided in the housing 1, and the rotating mechanism 4 includes a rotating motor 401, which is provided at the top of the housing 1, and the output shaft of the rotating motor 401 is transmission-connected with a worm 402, the worm 402 is meshed with a worm wheel 403, and the worm wheel 403 is connected with a rotating shaft 404, and both ends of the rotating shaft 404 are rotatably connected to the front and rear inner walls of the housing 1 through a second bearing seat 405.
[0029] It should be noted that the rotating mechanism is driven by the worm 402 and the worm wheel 403 and has a certain self-locking property, which can ensure stability and reliability during the working process.
[0030] Please refer to the attached Figure 5 , 6 As shown, the rotating shaft 404 is connected with a telescopic mechanism 5, and the telescopic mechanism 5 includes an electric telescopic rod 501, and the electric telescopic rod 501 is fixedly connected to the rotating mechanism 4, and the top of the electric telescopic rod 501 is connected with a clamping mechanism 6. The clamping mechanism 6 includes a mounting plate 601, and a clamping motor 602 is provided at the bottom center of the mounting plate 601. The output end of the clamping motor 602 is connected to a driving bevel gear 603, and the driving bevel gear 603 is meshed with a driven bevel gear 604. The driven bevel gear 604 is connected to a clamping screw 605, and one end of the clamping screw 605 away from the driven bevel gear 604 is rotatably connected to the inner wall of the mounting plate 601 through a third bearing seat 606.
[0031] It should be noted that there are four driven bevel gears 604, which are distributed circumferentially on the driving bevel gear 603. The mounting plate 601 is provided with a slide groove 607 above the four clamping screws 605. A clamping plate 608 is provided in the slide groove 607. The clamping plate 608 is sleeved on the clamping screw 605, and a rubber pad 609 is provided on the clamping surface of the clamping plate 608.

[0033] It should be noted that the vibration mechanism 7 can continuously vibrate the battery shell after flushing the electrolyte, which helps to separate the positive and negative electrode materials from the inner wall of the battery shell, allowing the positive and negative electrode materials to fall into the hopper 702. The hopper 702 can be slidably pulled out from the inside of the shell 1, thereby improving the quality of recycling and enabling better recycling and reuse of the positive and negative electrode materials.

After the flushing is completed, the electric telescopic rod 501 is retracted, and after the rotating mechanism rotates 60° clockwise, the electric telescopic rod 501 is extended again, and the battery shell is placed at the bottom of the silo 702 in a clamped state, and the vibration motor 706 is started, so that the vibration component 701 starts to drive the silo 702 to vibrate continuously, so that the positive and negative electrode materials in the battery shell are separated from the inside of the battery shell and fall into the silo 702, and then the electric telescopic rod 501 is retracted, and the rotating mechanism rotates 90° clockwise again, and the electric telescopic rod 501 is extended until the battery shell reaches the discharge port 102, the clamping mechanism 6 is relaxed, and the battery shell falls into the outer slot of the discharge port 102, and finally the electric telescopic rod 501 is retracted, and after the rotating mechanism 4 rotates 90° clockwise, the electric telescopic rod 501 is extended, so that the clamping mechanism 6 returns to the origin and waits for the next work.
