Description

Technical Field

[0001] This invention relates to the field of waste battery useful component regeneration technology, specifically to a fully automated power battery dismantling production line equipment. Background Technology

[0002] With the rapid growth in the number of new energy vehicles, the demand for recycling and processing used power batteries is becoming increasingly urgent. Used lead-acid batteries mainly consist of lead components, plastic casings, separators, and sulfuric acid electrolyte, with lead components having the highest recycling value. In the power battery dismantling process, the acid removal process is crucial for ensuring subsequent dismantling safety and resource recovery efficiency. The electrolyte inside the power battery is highly corrosive and volatile. If it cannot be completely removed through effective acid removal methods, it will not only corrode components of subsequent dismantling equipment and reduce the purity of the recycled plate materials, but also pose risks of burns to personnel and environmental pollution due to electrolyte leakage.

[0003] In existing technologies, the regeneration process of lead-acid battery components usually follows the process path of first draining the electrolyte and then sorting. During the acid draining and cutting process, most fixing mechanisms use unidirectional clamping and lack vertical constraints. When subjected to upward force, the battery is prone to tilting or displacement, affecting the accuracy and safety of disassembly. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a fully automated power battery dismantling production line equipment. This equipment effectively solves the problems in existing technologies where the regeneration process of lead-acid battery components typically follows a process path of first draining the electrolyte and then sorting the batteries. During the acid draining and cutting process, most fixing mechanisms use unidirectional clamping, lacking vertical constraints. When subjected to upward forces, the batteries are prone to tilting or displacement, affecting the accuracy and safety of dismantling.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a fully automated power battery dismantling production line equipment, comprising: The fixing part includes a worktable for placing an external battery. A cavity is opened in the middle of the worktable. A base is fixedly connected to the upper surface of the worktable. A horizontal hydraulic rod is provided on the outer surface of the base. A clamping plate that is slidably connected to the upper surface of the worktable is fixedly connected to the output end of the horizontal hydraulic rod. A top plate is fixedly connected to the upper surface of the base. A pressure plate is connected to the top plate through a vertical hydraulic rod provided on its lower surface. The drain section is used to drain the electrolyte in the battery. The drain section includes a support frame. The two sides of the support frame are fixedly connected to the lower surface of the workbench. The support frame has a fixing block inside, and a connecting rod is fixedly connected to the upper surface of the fixing block. The disassembly section includes a conveyor belt disposed on the outside of the workbench. A side plate fixedly connected to the outer surface of the workbench is disposed on the outside of the conveyor belt. A disassembly knife is fixedly connected to the side plate by a bracket fixed on its upper surface.

[0006] Furthermore, a fixing sleeve is provided inside the cavity to fit against the lower surface of the battery. The bottom end of the fixing sleeve is fixedly connected to the top end of the connecting rod. A liquid extraction tube is slidably connected to the inner circumference of the fixing sleeve. A positioning component is provided inside the liquid extraction tube to position the bottom of the inner wall of the battery casing, thereby determining the lowest point of the acid solution. Furthermore, the top of the liquid extraction tube adopts a pointed structure design, and a liquid extraction port is opened on the outer circumference of the liquid extraction tube.

[0007] Furthermore, the positioning component includes a vertical rod that is slidably connected to the inside of the liquid extraction tube. A groove is formed on the outer circumferential surface of the liquid extraction tube. A connecting rod is rotatably connected to the outer surface of the vertical rod. A positioning block is rotatably connected to the end of the connecting rod away from the vertical rod. The positioning block is slidably connected to the inner wall of the groove.

[0008] Furthermore, multiple chutes and extraction ports are provided, and the multiple chutes and extraction ports are staggered around the center line of the extraction pipe. The bottom of the inner wall of the chutes is flush with the middle of the extraction port groove to ensure that the extraction port groove is in the liquid phase region.

[0009] Furthermore, the groove of the liquid extraction port is provided with a filter screen, and the inside of the liquid extraction tube is provided with a confluence channel that communicates with the inside of the liquid extraction port. The confluence channel is designed with an inclined structure, and the inside of the liquid extraction tube is provided with a collection channel that communicates with the inside of the confluence channel. The liquid extraction port, the confluence channel, and the collection channel are arranged in sequence from top to bottom.

[0010] Furthermore, the outer surface of the positioning block is provided with a cutting groove, and the cutting groove and the outer contour of the positioning block form a cutting edge, which is used to perform circumferential cutting on the bottom shell wall of the battery during rotation, so as to eliminate the protruding obstacles caused by the tearing of the battery shell.

[0011] Furthermore, a connecting plate is fixedly connected to the bottom end of the support frame, and a drive seat connected to the lower surface of the liquid extraction pipe is provided on the upper surface of the connecting plate. A pusher is provided on the upper surface of the workbench, and a waste liquid tank is provided at the bottom of the workbench. A drain pipe connected to the inside of the collection tank is provided on the outer circumference of the liquid extraction pipe. A rotary sealing joint is provided at the connection between the liquid extraction pipe and the drain pipe to isolate the rotation of the liquid extraction pipe from the fixed state of the drain pipe.

[0012] The technical solution provided by this invention has the following advantages compared with the prior art: This invention features a fixing part, through which a horizontal hydraulic rod drives a clamping plate to slide along a slide rail, covering batteries of varying lengths. A pressure plate driven by a vertical hydraulic rod can be adjusted to accommodate batteries of different heights. Simultaneously, vertical constraint prevents tilting or displacement when the suction tube is inserted upwards from the bottom of the battery casing, ensuring disassembly accuracy and safety. No module replacement is required, reducing adjustment time and accommodating multiple battery types. Secondly, existing bottom piercing devices are prone to clogging the suction port due to casing tears and protrusions, increasing subsequent processing difficulty. When the suction tube is inserted from the bottom of the battery casing, due to the thickness of the casing bottom, the casing material is deformed by the radial thrust of the pointed tip during piercing, forming a ring-shaped protrusion with irregular edges that precisely covers the suction port on the outer surface of the suction tube. The ring-shaped protrusion, tightly fitting the outer circumference of the suction tube, completely seals the suction port slot. In the positioning component of this invention, the cutting groove of the positioning block and the outer contour of the positioning block form a cutting edge. When the liquid extraction tube rotates, it performs a ring cut on the annular protrusion, completely removing the obstruction and making the height of the inner wall of the battery casing near the liquid extraction tube level with the height of other parts. This facilitates the smooth entry of acid from the bottom of the battery into the liquid extraction port, reducing the amount of residual acid. Attached Figure Description

[0016] The present invention will be further described below with reference to embodiments.

[0017] Example: Please see Figures 1-10 This invention provides a technical solution: a fully automated power battery dismantling production line equipment, comprising: The fixing part 1 includes a workbench 11 for placing an external battery. A cavity 111 is opened in the middle of the workbench 11. A base 12 is fixedly connected to the upper surface of the workbench 11. A horizontal hydraulic rod 121 is provided on the outer surface of the base 12. A clamping plate 13 that is slidably connected to the upper surface of the workbench 11 is fixedly connected to the output end of the horizontal hydraulic rod 121. A top plate 14 is fixedly connected to the upper surface of the base 12. A pressure plate 15 is connected to the top plate 14 through a vertical hydraulic rod 141 provided on its lower surface. The drain section 2 is used to drain the electrolyte in the battery. The drain section 2 includes a support frame 21. The two sides of the support frame 21 are fixedly connected to the lower surface of the workbench 11. A fixing block 22 is provided inside the support frame 21. A connecting rod 23 is fixedly connected to the upper surface of the fixing block 22. The disassembly unit 3 includes a conveyor belt 31 disposed on the outside of the workbench 11. A side plate 32 fixedly connected to the outer surface of the workbench 11 is disposed on the outside of the conveyor belt 31. A disassembly blade 34 is fixedly connected to the side plate 32 by a bracket 33 fixed on its upper surface.

[0018] The cavity 111 is provided with a fixing sleeve 24 that fits against the lower surface of the battery. The bottom end of the fixing sleeve 24 is fixedly connected to the top end of the connecting rod 23. The inner circumferential wall of the fixing sleeve 24 is slidably connected with a liquid extraction tube 25. The liquid extraction tube 25 is provided with a positioning component 26 inside, which is used to position the bottom of the inner wall of the battery housing, thereby determining the lowest point of the acid solution. The top of the liquid extraction tube 25 adopts a pointed structure design, and the outer circumferential surface of the liquid extraction tube 25 is provided with a liquid extraction port 251.

[0019] The positioning component 26 includes a vertical rod 261 that is slidably connected to the inside of the liquid extraction tube 25. A groove 252 is provided on the outer circumferential surface of the liquid extraction tube 25. A connecting rod 262 is rotatably connected to the outer surface of the vertical rod 261. A positioning block 263 is rotatably connected to the end of the connecting rod 262 away from the vertical rod 261. The positioning block 263 is slidably connected to the inner wall of the groove 252.

[0020] Multiple chutes 252 and liquid extraction ports 251 are provided, and the multiple chutes 252 and liquid extraction ports 251 are staggered around the center line of the liquid extraction pipe 25. The bottom of the inner wall of the chutes 252 is flush with the middle of the opening of the liquid extraction port 251 to ensure that the opening of the liquid extraction port 251 is in the liquid phase region.

[0021] The outlet 251 is equipped with a filter screen 2511. The inside of the extraction pipe 25 is provided with a manifold 253 that communicates with the inside of the extraction port 251. The manifold 253 is designed with an inclined structure. The inside of the extraction pipe 25 is provided with a collection groove 254 that communicates with the inside of the manifold 253. The extraction port 251, the manifold 253, and the collection groove 254 are arranged in sequence from top to bottom.

[0022] The outer surface of the positioning block 263 is provided with a cutting groove 2631. The cutting groove 2631 and the outer contour of the positioning block 263 form a cutting edge, which is used to perform circumferential cutting on the bottom shell wall of the battery during rotation, so as to eliminate the protruding obstacles caused by the tearing of the battery shell.

[0023] A connecting plate 27 is fixedly connected to the bottom of the support frame 21. A drive seat 271 connected to the lower surface of the liquid extraction pipe 25 is provided on the upper surface of the connecting plate 27. A pusher 35 is provided on the upper surface of the workbench 11. A waste liquid tank 28 is provided at the bottom of the workbench 11. A drain pipe connected to the inside of the collection tank 254 is provided on the outer circumference of the liquid extraction pipe 25. A rotary sealing joint is provided at the connection between the liquid extraction pipe 25 and the drain pipe to isolate the rotation of the liquid extraction pipe 25 from the fixed state of the drain pipe.

[0024] The main methods for draining electrolyte fall into two categories: the tilting method and the top-piercing suction method. The tilting method uses a mechanical flipping mechanism to invert the battery, allowing gravity to cause the electrolyte to flow out. However, from the perspective of regenerating usable components, electrolyte drainage is extremely incomplete, with a large amount of electrolyte remaining in the battery separators, lead paste pores, and bottom sediment. This residual acidic liquid accompanies the lead components into subsequent crushing, sorting, and smelting processes. This not only severely corrodes crushing and sorting equipment, increasing maintenance costs, but also consumes more neutralizing agents and generates more acidic slag during smelting, directly reducing lead recovery rates and the purity of recycled lead, thus increasing regeneration costs. The top-puncture suction method involves puncturing the top cover of the battery and using vacuum suction to remove the electrolyte. Although the discharge rate is improved compared to the pouring method, it still cannot meet the stringent requirements for high-purity lead regeneration. Since the suction port is located in the upper middle part of the battery, the suction effect is still limited for electrolyte deposited at the bottom of the battery and lead mud precipitates containing a large amount of sulfate.

[0025] The fixing part 1 is used to accurately fix the external battery on the worktable 11 to avoid operational deviations caused by displacement during disassembly.

[0026] The workbench 11 is a rectangular steel structure platform with a cavity 111 in the middle, which serves as the operating channel for the drainage section 2.

[0027] Base 12 and clamping mechanism: The bases 12 are symmetrically distributed and fixed on both sides of the upper surface of the worktable 11. Each base 12 has a horizontally mounted horizontal hydraulic rod 121 on its outer surface, and its output end is connected to the clamping plate 13 by bolts. The horizontal hydraulic rod 121 can drive the clamping plate 13 to slide along the slide rail on the upper surface of the worktable 11. The clamping range can cover batteries of different lengths within a certain range, and horizontal positioning is achieved by clamping simultaneously from both sides.

[0028] Top plate 14 and pressing mechanism: Top plate 14 is a rectangular steel plate, fixed to the top of base 12. Two sets of vertical hydraulic rods 141 are symmetrically installed on the lower surface of top plate 14, and the output end is connected to pressing plate 15. Rubber is attached to the bottom of pressing plate 15. The vertical hydraulic rods 141 can drive pressing plate 15 to descend vertically, pressing the battery firmly onto worktable 11 and preventing the battery from bouncing in the vertical direction.

[0029] The drain section 2 achieves low-residue extraction of electrolyte through bottom puncture, precise positioning, and circumferential cutting clearance structure. The support frame 21 is an inverted U-shaped steel structure, which is fixed to the lower surface of the workbench 11 by bolts on both sides. The support frame 21 has a fixing block 22 horizontally fixed inside by bolts, and a connecting rod 23 passes through the upper surface of the fixing block 22.

[0030] The fixing sleeve 24 is a cylindrical structure with its top end flush with the upper surface of the workbench 11. When a battery is placed on the upper surface of the workbench 11, the top end of the fixing sleeve 24 fits against the lower surface of the battery to form a seal, and the bottom end is connected to the fixing block 22 via the connecting rod 23. The inner wall of the fixing sleeve 24 slides and rotates with the liquid extraction tube 25, which can move up and down axially under the drive of the drive seat 271.

[0031] The top of the extraction tube 25 features a solid conical tip structure, facilitating piercing of the bottom casing of the battery (piercing force is provided by the drive seat 271). Five extraction ports 251 are arranged in a circumferential array on the outer surface of the extraction tube 25. Each extraction port 251 has a filter screen 2511 embedded in its groove to prevent electrode residue from entering the extraction tube 25. Inside the extraction tube 25, there are a manifold 253 and a collector 254. The manifold 253 is designed at an angle to guide the electrolyte collected from each extraction port 251 to the collector 254. The bottom of the collector 254 is connected to the waste liquid tank 28 via a drain pipe, achieving a closed-loop transport of the electrolyte.

[0032] The positioning component 26 includes a vertical rod 261, five sets of connecting rods 262, and five positioning blocks 263. The vertical rod 261 is slidably engaged with the inside of the liquid extraction tube 25, and its bottom end is connected to the inside of the drive seat 271. The vertical rod 261 can move up and down axially along the inside of the liquid extraction tube 25.

[0033] The two ends of the connecting rod 262 are rotatably connected to the rotating shaft of the vertical rod 261 and the ear ring on the outer surface of the positioning block 263 respectively through pins. The positioning block 263 is embedded in the sliding groove 252 on the outer circumference of the liquid suction tube 25 and can slide along the inside of the sliding groove 252. When the vertical rod 261 rises, the connecting rod 262 pushes the positioning block 263 to extend outward along the slide groove 252 until the lower surface of the positioning block 263 is in contact with the bottom of the inner wall of the battery. Since the middle of the groove of the liquid extraction port 251 is flush with the bottom of the slide groove 252, the highest point of the groove of the liquid extraction port 251 is higher than the bottom of the inner wall of the battery, and the lowest point of the groove of the liquid extraction port 251 is lower than the bottom of the inner wall of the battery. This ensures that the liquid extraction port 251 is completely in the acid liquid phase zone, which can effectively reduce the amount of residual acid inside the battery.

[0034] The outer surface of the positioning block 263 is provided with a cutting groove 2631, which forms a sharp blade with the outer contour of the positioning block 263. The drive base 271 has a built-in rotary motor, which can drive the entire liquid extraction tube 25 and the positioning component 26 to rotate. The blade formed by the cutting groove 2631 and the outer contour of the positioning block 263 can cut around the tear protrusion at the bottom of the battery caused by puncture, thereby eliminating the blockage of the liquid extraction port 251.

[0035] The connecting plate 27 is fixed to the bottom of the support frame 21, and its upper surface is bolted with a drive seat 271 (integrating a lifting cylinder and a rotary motor) to provide lifting and rotation power for the suction pipe 25. The positions of the drive seat 271 and the fixing block 22 relative to the connecting plate 27 are adjustable to accommodate batteries with different numbers of internal partitions. A waste liquid tank 28 is provided at the bottom of the workbench 11 to collect leaked electrolyte and waste liquid transported by the drain pipe.

[0036] The disassembly section 3 is used to cut and transport the drained battery casings to the next process. The conveyor belt 31, a chain plate type, is located outside the workbench 11, flush with its upper surface, and is used to receive the disassembled battery components. The surface of the conveyor belt 31 is covered with an acid-resistant plastic sheet to prevent residual electrolyte from corroding the chain. The side plate 32 is fixed to the outer end of the workbench 11, and its top is mounted with a disassembly blade 34 via a bracket 33. The disassembly blade 34 is horizontally positioned to cut the top of the battery casing. A pusher 35 is installed on the upper surface of the workbench 11 away from the conveyor belt 31, pushing the drained battery to the cutting position at the disassembly blade 34. After cutting, the battery enters the upper surface of the conveyor belt 31.

[0037] The process of fixing the battery: In the initial state, both the horizontal hydraulic rod 121 and the vertical hydraulic rod 141 are in a retracted state, the distance between the two clamping plates 13 is at its maximum within its stroke range, and the pressure plate 15 is at its highest point within its stroke range. The top of the fixed sleeve 24 is always flush with the upper surface of the worktable 11, the liquid extraction tube 25 is in a retracted state, the highest point of the top of the liquid extraction tube 25 is lower than the top of the fixed sleeve 24, and the highest point of the liquid extraction tube 25 is inside the cavity 111. The positioning member 26 is also in a retracted state inside the liquid extraction tube 25, the outer surface of the positioning block 263 coincides with the outer circumferential surface of the liquid extraction tube 25, and is in contact with the inner circumferential wall surface of the fixed sleeve 24.

[0038] An external robotic arm moves the battery to the upper surface of the worktable 11, at which point the lower surface of the battery is in contact with the top of the fixing sleeve 24. The horizontal hydraulic rods 121 on both sides are activated. Under the action of the horizontal hydraulic rods 121, the clamping plates 13 on both sides move towards each other, sliding along the slide rails on the upper surface of the worktable 11 towards the battery in the middle. A rubber layer is provided on the outer surface of the clamping plates 13 away from the horizontal hydraulic rods 121. As the clamping plates 13 continue to move, the rubber layer contacts the outer surface of the battery, completing the horizontal positioning. The vertical hydraulic rod 141 on the lower surface of the top plate 14 is activated, driving the pressure plate 15 on its lower surface to press against the upper surface of the battery, thus fixing the battery in the vertical direction.

[0039] The process of removing acid from inside the battery: The drive seat 271, fixed to the upper surface of the connecting plate 27, drives the suction tube 25 to rise. The pointed tip of the suction tube 25 rises vertically, passes through the cavity 111, and the tip of the suction tube 25 is higher than the fixing sleeve 24, piercing into the bottom housing of the battery. During the rising process of the suction tube 25, the outer circumferential wall of the suction tube 25 always maintains a sliding fit with the inner wall of the fixing sleeve 24. The fixing sleeve 24 plays a guiding role, avoiding deviation in the subsequent piercing position due to trajectory deviation.

[0040] After the shell is punctured, the second set of miniature hydraulic cylinders (used to drive the vertical rod 261) built into the drive seat 271 is activated. Its output rod extends upward along the axis of the suction tube 25 and is rigidly connected to the bottom end of the vertical rod 261 through a coupling, driving the vertical rod 261 to rise vertically along the guide hole inside the suction tube 25.

[0041] As the vertical rod 261 rises, multiple sets of rotating shafts (evenly distributed along the circumference) on its outer surface move upwards simultaneously. Each set of rotating shafts is rotatably connected to a connecting rod 262 via bearings. Under the upward traction of the rotating shaft, the end of the connecting rod 262 connected to the vertical rod 261 rises with the shaft, while the end connected to the positioning block 263, limited by the sliding fit between the positioning block 263 and the slide groove 252, cannot rise synchronously with the near end, causing the tilt angle of the connecting rod 262 to gradually increase. As the vertical rod 261 continues to rise, the connecting rod 262 continuously approaches a horizontal state. When the vertical rod 261 rises to a preset stroke, the connecting rod 262 completely transitions to a horizontal state, at which point the thrust of the connecting rod 262 on the positioning block 263 reaches its maximum value.

[0042] Under the horizontal thrust of the connecting rod 262, the positioning block 263, which is connected to the far end of the connecting rod 262 via a rotating shaft, slides outward along the inner wall of the slide groove 252. At the same time, the cutting groove 2631 opened on the outer surface of the positioning block 263 extends synchronously with the positioning block 263. At this time, the lower surface of the positioning block 263 does not contact the lower surface of the inner wall of the battery casing, and is located between the bottom of the inner wall of the casing and the plate group (in the structural design of power batteries, in order to avoid the plate group from directly contacting the bottom of the casing and to prevent the plate from short-circuiting or causing local corrosion due to electrolyte deposition, the bottom of the inner wall of the casing is generally provided with plate support pads, which maintain a distance between the lower surface of the plate group and the bottom of the inner wall of the casing).

[0043] Because the bottom of the inner wall of the chute 252 is pre-designed to be flush with the middle of the extraction port 251, when the lower surface of the positioning block 263 is in contact with the bottom of the shell (the lowest point of the acid), the middle of the extraction port 251 is exactly flush with the lowest point of the acid surface, ensuring that the extraction port 251 is completely in the liquid phase region. At this time, the manifold 253 inside the extraction tube 25 is connected to the extraction port 251, preparing a channel for subsequent electrolyte extraction. At the same time, the cutting edge formed by the outer surface of the positioning block 263 and the cutting groove 2631 is also close to the inner wall of the bottom of the shell, preparing for subsequent circumferential cutting of the shell tearing protrusion.

[0044] After the positioning component 26 is fully extended, the drive seat 271 drives the positioning component 26 and the suction tube 25 to rotate and move downwards until the lower surface of the positioning block 263 in the extended state contacts the bottom of the inner wall of the battery casing, stopping the descent of the suction tube 25. The drive seat 271 drives the suction tube 25 to rotate at a constant speed around its own axis. When the suction tube 25 rotates, it drives the positioning block 263, which is close to the bottom inner wall of the casing, to make a circular motion. The cutting edge formed by the cutting groove 2631 and the outer contour on the outer surface of the positioning block 263 contacts the tear protrusion on the bottom of the casing in a line contact manner. Since the hardness of the cutting edge is much higher than that of the plastic of the battery casing, the cutting edge generates a continuous cutting force on the protrusion during the rotation. The sharp cutting edge of the cutting groove 2631 first cuts into the top of the protrusion, and gradually peels the protrusion off from the bottom of the casing as the suction tube 25 rotates and moves downwards, forming a circular cutting trajectory.

[0045] To prevent plastic debris generated during cutting from clogging the filter screen 2511 of the extraction port 251, the blade of the positioning block 263 adopts a forward-tilting layout. The cutting surface of the cutting groove 2631 is inclined at an angle to the direction of rotation. During cutting, the debris is pushed towards the outer area of ​​the bottom of the housing (away from the extraction port 251) under the action of centrifugal force. After the blade completes the circumferential cut, the tear protrusion of the housing is completely peeled off, and the load torque of the rotary motor will decrease significantly. After the torque sensor of the drive seat 271 detects this change, it sends a circumferential cut completion signal to the control system. At this time, the extraction tube 25 continues to rotate (to provide auxiliary stirring for electrolyte extraction), and enters the next stage of the electrolyte extraction process.

[0046] After the circumferential cutting completion signal is triggered, the control system immediately starts the negative pressure pump connected to the waste liquid tank 28, creating a stable negative pressure environment through the drain pipe, the outer stator of the rotary sealing joint, and the collection tank 254 and confluence tank 253 inside the extraction pipe 25. The negative pressure is transmitted to the extraction port 251 through the confluence tank 253. At this time, the extraction port 251 is completely in the acid liquid phase region, and the electrolyte begins to enter the extraction channel under the action of negative pressure. The electrolyte extraction path follows the sequence of extraction port 251, confluence tank 253, collection tank 254, rotary sealing joint, drain pipe to waste liquid tank 28.

[0047] Five extraction ports 251 are staggered circumferentially around the axis of the extraction pipe 25. Each extraction port 251 has a filter screen 2511 made of titanium alloy, which filters electrode residue in the electrolyte and prevents clogging of the manifold 253. The manifold 253 is designed to slope downwards. During rotation, the centrifugal force generated on the inner wall of the manifold 253 assists the electrolyte in flowing towards the collection tank 254, increasing the flow rate compared to static extraction. The collection tank 254 is a vertical channel, its bottom connected to the annular groove of the rotor inside the rotary sealing joint. After the electrolyte gathers in the collection tank 254, it flows through the annular groove into a fixed drain pipe, ultimately entering the waste liquid tank 28 for centralized treatment.

[0048] After the suction tube 25 stops rotating, the miniature hydraulic cylinder of the drive base 271 is activated, causing the vertical rod 261 to move downward relative to the suction tube 25. The connecting rod 262 returns from a horizontal state to an inclined state, pulling the positioning block 263 to slide inward along the slide groove 252 until the positioning block 263 is completely retracted into the suction tube 25 (to avoid scratching or jamming the positioning block 263 during retraction). Subsequently, the lifting hydraulic cylinder of the drive base 271 is activated, causing the suction tube 25 to retract vertically downward along the inner wall of the fixed sleeve 24 until the tip of the suction tube 25 is lower than the top plane of the fixed sleeve 24, completing the entire drainage process.

[0049] The process of splitting the top of the battery casing: After the liquid extraction is completed, the pusher 35 pushes the battery towards the conveyor belt 31. Since the disassembly blade 34 is horizontally placed above the side plate 32, the battery and the disassembly blade 34 will move relative to each other. The large contact area between the pushing surface of the pusher 35 and the side of the battery can prevent the battery from tilting during pushing. The cutting path is preset to a horizontal cut along the height of the battery casing. The upper edge of the disassembly blade 34 cuts into the upper half of the casing, and the lower edge of the disassembly blade 34 cuts into the lower half of the casing, exposing the internal substrate of the battery for separation in the next process.

[0050] In summary, this battery dismantling equipment has the following advantages: Advantage 1: Existing equipment's fixing mechanisms are mostly rigid structures, only suitable for batteries of a single length or width. Changing battery types requires replacing the clamping module, resulting in long adjustment cycles. In this invention, the horizontal hydraulic rod 121 of the fixing part 1 drives the clamping plate 13 to slide along the slide rail, covering batteries of different lengths. The vertical hydraulic rod 141 drives the pressure plate 15, which can be adjusted to accommodate batteries of different heights. No module replacement is required, shortening the adjustment time for battery changes and accommodating various battery types such as lead-acid batteries and square lithium-ion batteries.

[0051] Advantage 2: Existing tilting methods rely on mechanical inversion for electrolyte drainage, which easily leaves electrolyte residue in the separators, lead paste pores, and bottom sediment. This high residue level leads to increased corrosion of subsequent crushing and sorting equipment, increased consumption of neutralizing agents during smelting, higher levels of acidic slag, and reduced lead recovery rate. Furthermore, the traditional suction equipment's extraction port 251 is easily clogged by electrode residue, requiring frequent shutdowns for cleaning. This invention, through the lower surface of the positioning block 263 in the positioning component 26 adhering to the bottom of the shell, ensures that the extraction port 251 is completely in the liquid phase region. When the extraction pipe 25 rotates, the centrifugal force of the manifold 253 assists in electrolyte flow. Combined with negative pressure suction, the electrolyte residue level is significantly reduced, directly decreasing corrosion of subsequent equipment, reducing the consumption of smelting neutralizing agents, improving lead recovery rate, and lowering lead recycling costs.

[0052] Advantage 3: Existing bottom puncture equipment is prone to clogging the suction port 251 due to shell tearing and protrusions, increasing the difficulty of subsequent processing. When the suction tube 25 is inserted from the bottom of the battery casing, due to the certain thickness of the bottom of the casing, the casing material is squeezed and deformed towards the inside of the puncture hole during the puncture process by the radial thrust of the pointed end, forming a ring-shaped protrusion with irregular edges, which exactly covers the suction port 251 on the outer surface of the suction tube 25. After the ring-shaped protrusion fits tightly against the outer circumference of the suction tube 25, it completely seals the groove of the suction port 251. If the height of the annular protrusion is greater than the height of the groove of the extraction port 251, the extraction port 251 will be completely blocked, and the acid will not be able to enter the extraction channel.

[0053] If the height of the annular protrusion is less than the height of the suction port 251, only the upper part of the slot space can be retained, and the edge of the protrusion is easy to scratch the filter screen 2511 of the suction port 251, resulting in a decrease in the suction flow rate. At the same time, the residual acid will form a new residual dead corner around the annular protrusion.

[0054] In the positioning component 26 of the present invention, the cutting groove 2631 of the positioning block 263 and the outer contour of the positioning block 263 form a cutting edge. When the liquid extraction tube 25 rotates, it performs a ring cut on the annular protrusion, completely removing the obstruction, so that the height of the inner wall of the battery casing near the liquid extraction tube 25 is flush with the height of other parts, which makes it easy for the acid at the bottom of the battery to enter the liquid extraction port 251 smoothly, reducing the amount of acid residue.

[0055] Fourthly, the bottom of the inner wall of the chute 252 is pre-designed to be flush with the middle of the outlet 251. When the positioning block 263 cuts the annular protrusion and its lower surface is in contact with the bottom of the housing, the middle of the outlet 251 is exactly flush with the lowest point of the acid liquid level. Even if the acid continues to drop, at the end of the acid discharge, the lower half of the outlet 251 will still be submerged in the accumulated liquid. The height of the lowest point of the outlet is lower than the lowest point of the battery housing, which can ensure that the acid continuously enters the outlet 251.

[0056] Fifthly, the position of the suction port 251 in traditional bottom-mounted suction devices is fixed and cannot be dynamically adjusted according to the lowest point of acid deposition inside the battery. The thickness of the bottom of the battery casing varies. If the suction pipe 25 is inserted to the rated height, when the bottom of the battery casing is thicker, the groove of the suction port 251 will be inside the casing or at the bottom, preventing drainage. When the bottom of the battery casing is thinner, the lowest point of the groove of the suction port 251 will be higher than the bottom of the inner wall of the battery casing, preventing acid from draining between the lowest point of the groove of the suction port 251 and the lower surface of the inner wall of the battery casing. In the drain section 2 of the present invention, after the drain pipe 25 is inserted into the battery housing from the bottom, a plurality of horizontally arranged positioning blocks 263 are positioned in the vertical direction between the bottom of the inner wall of the battery housing and the lower surface of the battery plate assembly. Then the drain pipe 25 is moved down to ensure that the lower surface of the positioning block 263 is flush with the bottom of the inner wall of the battery housing. This method can be applied to battery housings of different thicknesses, ensuring that the drain port 251 is within the optimal range and avoiding deviations in the draining effect caused by differences in housing thickness.
