The whole machine integrates automatic operation of the whole disassembly process, is suitable for batteries of multiple specifications, and does not need to frequently replace tooling. The equipment structure is simple, the operation and maintenance cost is low, the integrated shell recycling module saves the supporting extrusion equipment, and the disassembly safety, production efficiency and recycling economic benefits are considered.

Description

Technical Field

[0001] This invention belongs to the field of lithium battery disassembly technology, and particularly relates to a device and method for separating and disassembling the cell and casing of a single battery cell. Background Technology

[0002] With the rapid popularization of new energy vehicles, energy storage devices, and portable digital products, lithium-ion batteries have become the most widely used energy storage devices due to their advantages such as high energy density, long cycle life, and excellent charge and discharge performance. Along with the large-scale installation and iterative upgrades of lithium batteries, a large number of retired lithium batteries are entering the scrapping and recycling stage. Retired lithium batteries contain various high-value metal resources such as lithium, nickel, cobalt, copper, and aluminum. At the same time, structural components such as the casing, cells, top cover, terminals, and tabs can all be reused. Standardized and efficient dismantling and recycling processes are the core prerequisites for realizing the recycling of retired lithium batteries, reducing resource waste, and avoiding environmental pollution. They are also a key link in the green and sustainable development of the new energy industry.

[0003] Currently, the recycling and dismantling processes for retired lithium batteries are mainly divided into two categories: traditional mechanical cutting and laser cutting for refined dismantling. However, both of these cutting and dismantling processes have significant technical drawbacks. After the existing cutting process, the battery casing has a high degree of closure, and the cell and casing are tightly fitted with no separation gap. There is a lack of dedicated gap widening and pre-loosening processes. Directly clamping and extracting the cell can easily lead to cell tearing, tab breakage, and terminal deformation, causing damage to core components and significantly increasing dismantling losses. The dismantling process can easily cause damage to the cell's active materials, damage to the terminal tab structure, and severe casing deformation, making it impossible to achieve refined and complete separation of each core component. This significantly reduces the reuse value of battery materials and structural components. Furthermore, the crushing process can easily cause safety risks such as dust pollution, electrolyte leakage, and short circuit fires, resulting in low recycling yield and resource utilization rates.

[0004] Therefore, given the common technical problems of low dismantling accuracy and high component damage rate in current retired lithium battery dismantling processes, there is an urgent need for a refined laser dismantling and grading separation process for retired lithium batteries to achieve precise and complete separation of lithium battery cells and casings.

[0015] A method for separating and disassembling a single-cell battery cell from its casing, comprising using any of the single-cell battery cell and casing separation and disassembly devices described herein to disassemble the single-cell battery after laser cutting, wherein a circumferential slit is formed between the top cover and the casing of the laser-cut single-cell battery, and a central slit is formed on both narrow sides of the casing after laser cutting; the disassembly method includes: Step A: Fix the laser-cut individual cell onto the slit table, with the center cuts on both sides of the narrow edge of the individual cell casing facing the pry bar of the slit assembly. Step B: Based on the height of the center cut, the prying lifting assembly adjusts the height of the pry piece by lifting to ensure that the first and second contact surfaces of the pry piece's insert part can be inserted into the center cut. The prying displacement component drives the prying component to slide along the prying groove of the opening table so that the prying piece is close to the center cut and the locking part of the prying piece is locked into the center cut. The pry bar lifting assembly raises the pry bar. During the rise of the pry bar, its rotating part, under the torsional elastic force of the elastic element, drives the insert part to swing down around the pry bar mounting axis. This causes the insert part to automatically compensate for the insertion into the center cut. After the insert part can no longer swing down, the pry bar lifting assembly continues to raise the pry bar, causing the insert part to continuously output a radial expansion force that acts vertically on the shell walls on both sides of the narrow edge of the shell to widen the center cut. This causes the shell wall to be turned up relative to the center cut, thereby expanding the space between the battery cell and the inside of the shell. If the insert part disengages from the center cut during the lifting process of the pry bar, the insert part will swing back due to inertia under the torsional elastic force of the elastic element. The swing back motion can cause the insert part to re-insert into the center cut. Step C: Place the individual battery cells after the slits are cut in Step B onto the flipping table, with the center slits on both sides of the narrow sides of the individual battery cell casing facing the flipping single-sided slide table and the top cover facing the receiving upright plate. Step D: The flip displacement component drives the flip single-sided slide to slide along the flip groove of the flip table, so that the flip clamping plate holds the narrow sides of the single battery casing with the center cut on both sides. The flip motor drives the flip table to flip, so that the top cover and cell of the single battery fall out towards the receiving plate under the action of its own gravity. Synchronously, the single-sided sliding table drives the flipping clamp to extend away from the receiving vertical plate, clamping the shell and displacing it away from the receiving vertical plate. Under the combined force of its own weight and the reverse pulling force of the casing, the top cover of a single battery cell can detach from the casing and the cell can be exposed outside the casing. At this time, most of the cell remains inside the casing. Step E: Place the single cell processed in step D on the reference platform, with the top cover of the single cell facing the first clamping and extraction mechanism and the tail of the casing facing the second clamping and extraction mechanism. Step F: The lifting assembly raises and lowers the first clamping assembly so that the two first clamping blocks are aligned with the top cover of the single battery cell. The lateral movement assembly drives the first clamping assembly to approach the top cover of the single battery cell so that the top cover of the single battery cell falls between the two first clamping blocks. The first clamping double-sided slide table drives the two first clamping blocks to clamp the top cover of the single battery cell. Synchronously, the sliding component drives the second clamping component to approach the tail of the single battery casing, so that the narrow edges with central slits on both sides of the single battery casing fall between the two second clamping blocks. The second clamping double-sided slide table drives the two second clamping blocks to clamp the single battery casing, and the limiting cylinder drives the limiting pressure plate to press against the upper part of the single battery casing. Step G: The second clamping and extraction mechanism remains stationary, and the lateral movement component drives the first clamping component away from the reference stage, so that the first clamping component pulls the top cover of the single battery cell together with the terminal tabs from the cell. During the process of pulling the top cover from the cell, the cell is further exposed to the casing. The first clamping component clamps the top cover and moves it above the collection box. The push cylinder drives the push plate to extend and push the top cover into the collection box. Step H: The lateral movement component re-drives the first clamping component closer to the cell, so that the two first clamping blocks clamp the part of the cell exposed outside the casing and keep it stationary. The limit cylinder drives the limit pressure plate to release the casing. The sliding component drives the second clamping component away from the reference stage, so that the second clamping component pulls the single battery casing away from the cell. Step 1: The second clamping assembly clamps the housing and moves it above the receiving plate. The receiving cylinder drives the receiving plate to rise to receive the housing and then fall back to its original position. The pushing cylinder drives the pushing plate to push the housing from the receiving plate into the pressing platform. The pressing cylinder drives the pressing plate to press down to flatten the housing on the pressing platform. The feeding cylinder drives the feeding plate to push the flattened housing from the pressing platform into the recycling bin.

[0016] The advantages of this invention over the prior art are: 1. This device employs a grading process involving pre-loosening the slit, pre-separating the battery by gravity flipping, and gentle extraction in stages. Throughout the process, force is applied only to the casing to isolate the battery cells. The top cover, tabs, battery cells, and aluminum casing are completely separated without issues such as cell tearing or tab breakage. This avoids the problems of metal mixing and active material loss caused by fragmentation disassembly, significantly increasing recycling revenue. At the same time, it reduces safety and environmental hazards such as electrolyte leakage, short circuit fires, and dust pollution, achieving non-destructive and refined disassembly of all battery components and resulting in a higher resource recovery rate. 2. This device integrates the entire process of slit opening, pre-separation, dual-station clamping and extraction, and shell flattening and recycling. It operates fully automatically and continuously, greatly reducing manual handling and operation. The slit opening and flipping mechanism adopts a gear and rack synchronous centering structure, combined with a multi-degree-of-freedom adjustable clamping module, which is compatible with various square and blade lithium batteries. It does not require frequent tooling changes, has a low equipment failure rate, is simple to maintain, and significantly improves the production capacity of a single production line.

Detailed Implementation

[0019] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product, or end that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or ends.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This application proposes a device for separating and dismantling a single battery cell from its casing, used to dismantle single batteries that have undergone laser cutting, including but not limited to retired prismatic lithium batteries and blade lithium batteries. Figure 1 As shown, the single cell after laser cutting can be understood as follows: the laser performs a circumferential cut on the top cover A1 of the lithium battery, forming a circumferential cut A3 between the top cover A1 and the casing A2. The circumferential cut A3 allows the top cover A1 of the lithium battery to be initially separated from the casing A2. At this time, the top cover A1 of the lithium battery is connected to the cell inside the casing A2 through the terminal post and the terminal tab. The laser then performs a side cut on the middle of the narrow sides of the casing A2 of the lithium battery, forming a middle cut A4 on the narrow sides of the casing A2 of the lithium battery. The middle cut A4 facilitates the subsequent separation of the cell from the casing A2.

[0024] Based on this, the present application provides a cell and casing separation and dismantling device for a single battery cell, which is used to dismantle a single battery cell that has a central cut and a circumferential cut after the aforementioned laser cutting, comprising: like Figure 2 , Figure 3 and Figure 4As shown, a slotting mechanism 5 is configured with a slotting displacement component 51, a slotting lifting component 52, and a slotting component 53. The slotting displacement component 51 is used to drive the slotting lifting component 52 and the slotting component 53 to move laterally on the slotting platform 54. The slotting lifting component 52 is used to lift the slotting component 53. The slotting component 53 is provided with a pry bar 534. The pry bar 534 is used to insert into the center cut of the single battery casing located on the slotting platform 54 and to expand the center cut under the lifting and lowering cooperation of the slotting lifting component 52. In this embodiment, the pry slot displacement component 51 is used to drive the pry slot lifting component 52 and the pry slot component 53 to lean against the single cell fixed on the slit table 54, and to enable the pry piece 534 of the pry slot component 53 to be progressively inserted into the central slit of the single cell. After the pry piece 534 is inserted into the central slit, the pry slot lifting component 52 drives the pry piece 534 to rise, so that the pry piece 534 can continuously output a radial expansion force acting vertically on the single cell shell wall, forcibly expanding the central slit, thereby effectively overcoming the static friction force caused by heat effect and interference fit after laser cutting. As the central slit expands, the space between the shell and the internal cell also expands, providing a disassembly space basis for the subsequent removal of the cell from the shell.

[0025] like Figure 5 , Figure 6 and Figure 7 As shown, a discharging mechanism 6 is configured with a flipping displacement component 61, a flipping component 62, and a clamping and discharging component 63. The flipping displacement component 61 is used to drive the clamping and discharging component 63 to move laterally on the flipping table 64. The flipping component 62 is used to flip the flipping table 64. The clamping and discharging component 63 is used to clamp the casing of a single battery cell located on the flipping table 64 and drive the tail of the casing of the single battery cell to move. With the cooperation of the flipping component 62 and the clamping and discharging component 63, the battery cell of the single battery cell is exposed from the inside of the casing and the top cover of the single battery cell is initially separated from the casing. In this embodiment, after being processed by the slit mechanism 5, the individual battery cell has a basic space for initial separation between its casing and internal cell. Based on this, the flipping displacement component 61 is used to drive the clamping and pouring component 63 to approach and clamp the individual battery cell located on the flipping platform 64. Then, the flipping component 62 flips the flipping platform 64, allowing the cell cell to partially detach from the casing under its own gravity. At the same time, the clamping and pouring component 63 clamps the casing and moves the casing towards its tail, further separating the casing from the cell. Under the action of the double reverse separation force, the cell can be smoothly exposed from the casing without damage. It should be noted that after this step, most of the cell remains inside the casing.

[0026] like Figures 8 to 10As shown, a first clamping and extraction mechanism 2 is configured with a lifting and traversing assembly 21 and a first clamping assembly 22. The lifting and traversing assembly 21 is used to drive the first clamping assembly 22 to lift and / or traverse. The first clamping assembly 22 is used to clamp the top cover or cell of a single battery located on the reference platform 1. A second clamping and extraction mechanism 3 is configured with a sliding component 31, a limiting component 33, and a second clamping component 32. The sliding component 31 is used to drive the second clamping component 32 and the limiting component 33 to move laterally. The second clamping component 32 is used to clamp the housing of the single battery cell, and the limiting component 33 is used to press against the housing of the single battery cell. When the second clamping component 32 and the limiting component 33 cooperate to restrict the housing of the single battery cell to the reference platform 1, the lifting and traversing component 21 cooperates with the first clamping component 22 to detach the top cover of the single battery cell from the housing and the cell, or to detach the cell from the housing.

[0027] In this embodiment, the single battery cell processed by the pouring mechanism 6 is placed on the reference platform 1. The first clamping and extraction mechanism 2 is arranged on the left side of the reference platform 1, and the second clamping and extraction mechanism 3 is arranged on the right side of the reference platform 1. The reference platform 1 has a notch facing the first clamping and extraction mechanism 2, which facilitates the first clamping and extraction mechanism 2 to clamp the top cover or cell of the single battery cell from the top and bottom. The lifting and traversing assembly 21 adjusts the first clamping assembly 22 to a suitable clamping height for clamping the top cover or cell of the single battery cell by lifting and lowering the first clamping assembly 22. The lifting and traversing assembly 21 adjusts the first clamping assembly 22 to a distance close to the single battery cell and suitable for clamping the top cover or cell by traversing the first clamping assembly 22. After the first clamping assembly 22 clamps the top cover or cell, the lifting and traversing assembly 21 then adjusts the first clamping assembly 22 to a position away from the reference platform 1. During the process of moving away, the top cover or cell is extracted from the housing.

[0028] Furthermore, the sliding component 31 is used to adjust the limiting component 33 and the second clamping component 32 to a distance close to the single battery cell and suitable for clamping the single battery cell housing. Before the top cover is removed, the second clamping component 32 needs to clamp the narrow edges on both sides of the single battery cell housing, while the limiting component 33 presses against the top of the housing. The housing and cell of the single battery cell are restricted on the reference platform 1 by the second clamping component 32 and the limiting component 33, which facilitates the removal of the top cover by the first clamping component 22. Alternatively, after the top cover is removed, the first clamping component 22 clamps the cell, the limiting component 33 releases the pressure on the housing, and the sliding component 31 is used to adjust the second clamping component 32 that clamps the housing to a position away from the reference platform 1. During the process of moving away, the cell separates from the housing.

The output end of the prying displacement cylinder 511 is connected to the first prying slide 512. The first prying slide 512 is slidably connected to the first prying guide rail 514. The first prying slide 512 is equipped with the first prying rack 516. The first prying rack 516 meshes with the prying transmission gear 518 and abuts against the prying limiting guide wheel 519. The second prying slide 513 is slidably connected to the second prying guide rail 515. The second prying slide 513 is equipped with the second prying rack 517, which meshes with the prying transmission gear 518 and abuts against the prying limiting guide wheel 519.

[0030] In this embodiment, the output shaft of the prying displacement cylinder 511 can extend and retract to drive the first prying slide 512 to slide along the first prying guide rail 514. Since the first prying slide 512 is fixed with the first prying rack 516, the first prying slide 512 simultaneously drives the first prying rack 516 to slide during the sliding process. The first prying rack 516 meshes with one side of the prying drive gear 518, thus driving the prying drive gear 518 to rotate. The second prying rack 517 meshes with... Located on the other side of the prying drive gear 518, the rotation of the prying drive gear 518 will drive the second prying rack 517 to slide synchronously, causing the first prying rack 516 and the second prying rack 517 to move synchronously in opposite directions. The second prying rack 517 is mounted on the second prying slide 513, so the sliding of the second prying rack 517 will drive the second prying slide 513 to slide along the second prying guide rail 515, causing the first prying slide 512 and the second prying slide 513 to move synchronously in opposite directions. The first prying rack 516 and the second prying rack 517 are both located between a prying limiting guide wheel 519 and the prying drive gear 518, so that the prying limiting guide wheel 519 can guide and limit the sliding of the first prying rack 516 and the second prying rack 517, preventing the first prying rack 516 and the second prying rack 517 from deviating.

[0031] Preferred, such as Figure 2 and Figure 3The slit table 54 shown is provided with a slit groove 541. The first slit slide 512 and the second slit slide 513 are both provided with slit fixing plates 531. The slit fixing plates 531 pass through the slit groove 541 to connect to the slit base 532 of the slit assembly 53. The slit fixing plates 531 can slide along the slit groove 541. The pry bar lifting assembly 52 includes a first pry bar lifting cylinder 521 and a second pry bar lifting cylinder 522. The first pry bar lifting cylinder 521 is mounted on the first pry bar slide 512 via a pry bar lifting cylinder mounting seat 523, and the second pry bar lifting cylinder 522 is mounted on the second pry bar slide 513 via another pry bar lifting cylinder mounting seat 523. The output ends of the first pry bar lifting cylinder 521 and the second pry bar lifting cylinder 522 are both connected to the pry bar base 532 of the pry bar assembly 53.

[0032] In this embodiment, the first pry bar slide 512 and the second pry bar slide 513 can slide synchronously in opposite directions, thus driving the respective pry bar fixing plates 531 to slide synchronously in opposite directions within the pry bar groove 541; each of the two pry bar fixing plates 531 is fixed with a pry bar base 532 of the pry bar assembly 53; the cylinder body of the first pry bar lifting cylinder 521 is mounted on the first pry bar slide 512 via a pry bar lifting cylinder mounting seat 523, and the cylinder body of the second pry bar lifting cylinder 522 is mounted on another pry bar lifting cylinder mounting seat 541. 23 is installed on the second pry bar slide 513, and the output ends of the first pry bar lifting cylinder 521 and the second pry bar lifting cylinder 522 are each fixed to the pry bar base 532 of the pry bar assembly 53. Therefore, when the first pry bar slide 512 and the second pry bar slide 513 slide in opposite directions synchronously, they will also drive the first pry bar lifting cylinder 521, the second pry bar lifting cylinder 522 and the two pry bar assemblies 53 to slide in opposite directions synchronously, thereby enabling the two pry bar assemblies 53 to simultaneously approach or move away from the single battery located in the middle of the opening platform 54.

[0033] Preferred, such as Figure 2 and Figure 4As shown, the pry slot assembly 53 includes a pry slot mounting shaft 533, a pry member 534, and a pry slot base 532. The pry slot mounting shaft 533 is mounted on the pry slot base 532. The rotating part 5341 of the pry member 534 is oscillatingly mounted on the pry slot mounting shaft 533 via a built-in elastic member 5345. The rotating part 5341 extends downward to form a locking part 5342. The first contact surface 5343 of the locking part 5342 is raised upward relative to the horizontal surface of the center cut. The second contact surface 5344 of the locking part 5342 is inclined relative to the first contact surface 5343, so that the first contact surface 5343 and the second contact surface 5344 can be inserted into the center cut.

[0034] In this embodiment, the pry bar mounting shaft 533 passes through the rotating part 5341 of the pry member 534 and is mounted on the pry bar base 532. The rotating part 5341 of the pry member 534 has an elastic element 5345 built in it, so that the pry member 534 can swing down around the pry bar mounting shaft 533 with a limited range under the torsional elastic force of the elastic element 5345. In this embodiment, the elastic element 5345 can be set as a compression spring or a torsion spring. The lower part of the rotating part 5341 extends into a card insertion part 5342. The first contact surface 5343 of the card insertion part 5342 is raised upward relative to the horizontal surface of the central cut. The second contact surface 5344 of the card insertion part 5342 is inclined relative to the first contact surface 5343, that is, the included angle of the cross section formed by the first contact surface 5343 and the second contact surface 5344 is less than 90 degrees. This facilitates the insertion of the card insertion part 5342 into the central cut. The upward-curving design of the first contact surface 5343 allows the tip of the card insertion part 5342 to penetrate deeper into the central cut during the prying process, making the contact between the card insertion part 5342 and the shell wall of the single battery more secure and making it easier to pry open the shell wall of the single battery.

[0035] Furthermore, the working principle of the pry bar 534 is as follows: When the insert part 5342 is inserted into the central cut, the first pry bar lifting cylinder 521 or the second pry bar lifting cylinder 522 drives the pry bar 534 of their respective pry bar components 53 to rise. As it rises, the rising force is converted into a torsional elastic force on the rotating part 5341 in the elastic member 5345, causing the entire pry bar 534 to swing downward around the pry bar. Since the torsional elastic force of the elastic member 5345 is limited, the pry bar 534 stops swinging after swinging to a certain extent, so that the pry bar 534 can continuously output a radial expansion force acting vertically on the wall of the single battery cell, forcibly expanding the central cut, effectively overcoming the static friction caused by heat and interference fit after laser cutting. As it continues to rise, the insert part 5342 continuously makes hard contact with the wall of the central cut, causing the wall of the central cut to deform. The deformation can be understood as the wall of the central cut flipping up to form a flange.

[0036] The working surface and point of action of the skid 534 are precisely defined on the inner wall and flange corresponding to the center cut. The resulting separation force acts only on the rigid shell throughout the entire process, actively isolating the battery cell body from the mechanical path. This ensures that during strong expansion, destructive loads such as squeezing and puncture will not be transmitted to the internal battery cell, thus protecting the integrity of the battery cell structure from the root.

[0037] Furthermore, the prying assembly 53 employs an elastic element 5345 built into the rotating part 5341, which can solve the problems of uneven gap width, thermal deformation of the shell, and dimensional tolerance fluctuations after laser cutting. The presence of the elastic element 5345 allows the inserting part 5342 of the prying piece 534 to automatically follow the actual gap trajectory and float and finely adjust its posture during insertion and opening. This ensures sufficient separation force for tight fit conditions and prevents jamming or shell edge breakage due to excessive rigidity of the mechanism.

[0038] Furthermore, during the process of inserting the insert portion 5342 of the pry bar 534 into the central cut and prying it open, the insert portion 5342 may detach from the central cut. In this case, due to the presence of the elastic element 5345, under the torsional elastic rebound force of the elastic element 5345, the insert portion 5342 can swing back and forth around the pry bar mounting axis 533. The process of swinging back and forth can be understood as follows: when the insert portion 5342 detaches from the central cut, under the force of the elastic element 5345, the insert portion 5342 swings upward and then swings back downward under the action of inertial elasticity. This allows the second contact surface 5344 of the insert portion 5342, which is inclined, to rub against the flange of the shell wall where the central cut is located. After swinging back downward, it swings back upward again under the action of inertial elasticity, causing the insert portion 5342 to re-insert into the central cut, effectively preventing the insert portion 5342 from falling off the central cut.

[0039] Preferred, such as Figure 7 As shown, the tilting displacement assembly 61 installed on the tilting table 64 includes a tilting displacement cylinder 611, a first tilting slide 612, a second tilting slide 613, a first tilting guide rail 614, a second tilting guide rail 615, a first tilting rack 616, a second tilting rack 617, a tilting transmission gear 618, and a tilting limit guide wheel 619. The output end of the flip displacement cylinder 611 is connected to the first flip slide 612. The first flip slide 612 is slidably connected to the first flip guide rail 614. The first flip slide 612 is equipped with the first flip rack 616. The first flip rack 616 meshes with the flip transmission gear 618 and abuts against the flip limit guide wheel 619. The second flip slide 613 is slidably connected to the second flip guide rail 615. The second flip slide 613 is equipped with the second flip rack 617. The second flip rack 617 meshes with the flip transmission gear 618 and abuts against the flip limiting guide wheel 619. The tilting table 64 is rotatably mounted between the two brackets 623 via a tilting shaft 622; The flipping assembly 62 includes a flipping motor 621, the output end of which is connected to a flipping shaft 622.

[0040] In this embodiment, the output shaft of the tilting displacement cylinder 611 can extend and retract to drive the first tilting slide 612 to slide along the first tilting guide rail 614. Since the first tilting slide 612 is fixed with the first tilting rack 616, the first tilting slide 612 drives the first tilting rack 616 to slide synchronously during the sliding process. The first tilting rack 616 meshes with one side of the tilting transmission gear 618, thus driving the tilting transmission gear 618 to rotate. The second tilting rack 617 meshes with the other side of the tilting transmission gear 618, so the rotation of the tilting transmission gear 618 will drive the second tilting rack 617 to slide synchronously, so that the first tilting rack 616 and the second tilting rack 617 move synchronously in opposite directions. The second tilting rack 617 is installed on the second tilting slide 613, so the sliding of the second tilting rack 617 will drive the second tilting slide 613 to slide along the second tilting guide rail 615, so that the first tilting slide 612 and the second tilting slide 613 move synchronously in opposite directions. The first flip rack 616 and the second flip rack 617 are both located between the flip limiting guide wheel 619 and the flip transmission gear 618, so that the flip limiting guide wheel 619 can guide and limit the sliding of the first flip rack 616 and the second flip rack 617, and prevent the first flip rack 616 and the second flip rack 617 from deviating.

[0041] Preferred, such as Figure 5 and Figure 6 As shown, the clamping and pouring assembly 63 includes a flipping single-sided slide 631 and a receiving upright plate 633, and a flipping clamping plate 632 is installed at the output end of the flipping single-sided slide 631. The receiving plate 633 is erected on the flipping table 64 and is used to receive the battery cells exposed in the housing during the flipping process. The flipping table 64 is provided with a flipping slide groove 641. The first flipping slide 612 and the second flipping slide 613 are both provided with a flipping fixing plate 642. The flipping fixing plate 642 passes through the flipping slide groove 641 to connect to the flipping single-sided slide table 631. The flipping fixing plate 642 can slide along the flipping slide groove 641.

[0042] In this embodiment, since the first flip slide 612 and the second flip slide 613 can slide synchronously in opposite directions, they can drive the respective flip fixing plates 642 to slide synchronously in opposite directions within the flip slide groove 641. Each of the two flip fixing plates 642 is fixed with a flip single-sided slide 631. Therefore, when the first flip slide 612 and the second flip slide 613 slide synchronously in opposite directions, they will also drive the left and right flip single-sided slides 631 to slide synchronously in opposite directions, thereby enabling the two flip single-sided slides 631 to simultaneously move closer to or further away from the single battery located in the middle of the flip platform 64.

[0043] Furthermore, the working principle of the discharge mechanism 6 is as follows: when the single battery cell after the prying treatment is placed in the middle of the flipping platform 64, the top cover of the single battery cell faces the receiving plate 633, and the center cuts on both sides of the narrow side of the housing face the flipping single-sided slides 631 on the left and right sides. The flipping displacement component 61 drives the flipping single-sided slides 631 on the left and right sides to approach the single battery cell until the flipping clamp 632 clamps the narrow side of the housing. Then, the flipping motor 621 starts to drive the flipping platform 64 to flip towards the receiving plate 633. Because there is a certain space between the cell and the housing after the prying treatment, and there is a gap between the top cover and the housing. Because of the circumferential cut, after flipping, the top cover, connected by the pole and the tab, tilts towards the receiving plate 633 under its own weight, with the battery cell attached to it. The receiving plate 633 abuts against the top cover. At the same time, the two flipping single-sided slides 631 drive their respective flipping clamps 632 to extend away from the receiving plate 633, causing the clamped shell to move away from the receiving plate 633. Driven by the pull-out force generated by the shell displacement and the double reverse force of the battery cell's own weight after flipping, the battery cell can be smoothly exposed inside the shell for a certain distance. It should be noted that at this time, most of the battery cell remains inside the shell.

[0044] This device uses the clamping and pouring component 63 to stably clamp the individual battery casing, and the flipping component 62 drives the clamped individual battery to flip to a preset angle, preferably 60°. It uses the weight of the battery cell itself as the separation force, without the need for additional pushing or pulling components. Under the premise of ensuring that the surface of the battery cell is undamaged, the battery cell can slide naturally from the casing, simplifying the operation process. Compared with the disadvantages of traditional crushing processing methods that cause greater damage to the core and result in the loss of some battery materials, this device can avoid the mechanical damage to the battery cell caused by cutting or crushing operations, achieve non-destructive separation of the battery cell and the casing, effectively prevent the loss of battery materials, significantly improve the recycling rate of battery materials, and avoid material waste. Furthermore, this device firmly clamps the individual battery cells using the clamping and dispensing component 63, ensuring that the lithium battery cells will not loosen or fall off during the flipping process. The clamping and dispensing component 63 clamps the lithium battery cells from opposite sides, ensuring a uniform distribution of clamping force and effectively preventing damage such as bumps and scratches to the cells caused by unstable clamping. At the same time, the stable clamping state ensures the accuracy of the flipping action, which is beneficial to ensuring the accuracy of subsequent cell recycling and processing.

[0045] Meanwhile, the flipping displacement component 61 adopts a bidirectional synchronous centering clamping structure, namely gear and rack linkage. This technology can automatically adapt to lithium batteries of different thicknesses or widths, ensuring that the clamping force always acts on the geometric center of the shell, avoiding uneven force on the shell or cell jamming during flipping due to clamping misalignment.

[0046] Preferred, such as Figure 8 and Figure 9 As shown, the lifting and traversing assembly 21 includes a traversing assembly 212 and a lifting assembly 211. The traversing assembly 212 includes a traversing slide rail 2121, a traversing slider 2122 and a traversing motor 2123. The lifting assembly 211 includes a lifting slide rail 2111, a lifting slider 2112 and a lifting motor 2113. The transverse motor 2123 is used to drive the transverse slider 2122 to slide on the transverse slide rail 2121, and the lifting motor 2113 is used to drive the lifting slider 2112 to slide on the lifting slide rail 2111; The lifting slide rail 2111 is slidably mounted on the transverse slide rail 2121 via the transverse slider 2122; The lifting slider 2112 is equipped with a first clamping fixing plate 2114, and the first clamping fixing plate 2114 is equipped with the first clamping assembly 22. In this embodiment, the lifting and traversing assembly 21 can be implemented using the following lifting and traversing structure, or it can be implemented using existing lifting or traversing structures, such as screw drive structures. In this embodiment, the transverse motor 2123 provides transverse force, causing the transverse slider 2122 to slide on the transverse slide rail 2121, allowing the transverse slider 2122 to move closer to or further away from the reference platform 1. Since the transverse slider 2122 is equipped with the lifting slide rail 2111, it can synchronously drive the lifting assembly 211 to move closer to or further away from the reference platform 1 along the X-axis. The lifting motor 2113 provides lifting power, causing the lifting slider 2112 to slide on the lifting slide rail 2111, allowing the lifting slider 2112 to move up and down along the Y-axis. Since the lifting slider 2112 is equipped with the first clamping fixing plate 2114, and the first clamping fixing plate 2114 is equipped with the first clamping assembly 22, it can synchronously drive the first clamping assembly 22 to move up and down. This allows for precise adjustment of the first clamping assembly 22's transverse movement along the X-axis and its vertical movement along the Y-axis using the lifting assembly 211 and the transverse component 212.

[0047] The first clamping assembly 22 includes a first clamping double-sided slide 221, and first clamping arms 222 are respectively installed on both sides of the first clamping double-sided slide 221. The first clamping arms 222 are configured with first clamping blocks 223. The first clamping double-sided slide 221 is used to drive the first clamping arm 222 to extend and retract so that the first clamping block 223 clamps or releases the top cover or cell of the single battery cell; In this embodiment, the first clamping double-sided slide 221 is provided with first clamping arms 222 on both sides, and the first clamping arms 222 are provided with first clamping blocks 223. The first clamping blocks 223 can clamp the top cover or battery cell by extending and retracting both sides of the first clamping double-sided slide 221.

[0048] Furthermore, in this embodiment, the first clamping block 223 is designed as an L-shaped structure, which utilizes the 90-degree concave angle of the L-shaped structure to perfectly fit the narrow edge of the top cover of the single battery cell.

[0049] The first clamping and fixing plate 2114 is also equipped with a pushing component 23, which includes a pushing cylinder 231 and a push plate 232, and the push plate 232 is disposed between the two first clamping blocks 223. After the top cover of the single battery cell is detached from the housing and the cell, the push cylinder 231 drives the push plate 232 to push the top cover of the single battery cell, which is held between the two first clamping blocks 223, down into the collection box.

[0050] In this embodiment, after the two first clamping blocks 223 clamp the top cover and move it away from the reference platform 1, causing the top cover to detach from the battery cell and the housing, the two first clamping blocks 223 will move laterally with the detached top cover to the top of the collection box. At this time, the pushing cylinder 231 drives the pushing plate 232 to extend, pushing the top cover clamped between the two first clamping blocks 223 into the collection box, completing the retrieval of the top cover. It should be noted that when the pushing plate 232 applies a pushing force against the top cover of the refrigerator, the two first clamping blocks 223 need to slightly loosen their grip on the top cover to avoid the clamping force of the two first clamping blocks 223 on the top cover resisting the pushing force of the pushing plate 232, which could damage the equipment or prevent the top cover from being pushed into the collection box.

[0051] Preferred, such as Figure 8 and Figure 10 As shown, the sliding assembly 31 includes a sliding rail 311, a sliding table 312, and a sliding motor 313. The sliding motor 313 is used to drive the sliding rail 311 to slide laterally relative to the sliding table 312. The sliding rail 311 is equipped with a second clamping fixing plate 314, and the second clamping fixing plate 314 is equipped with the second clamping assembly 32; The second clamping assembly 32 includes a second clamping double-sided slide 321, with second clamping arms 322 respectively installed on both sides of the second clamping double-sided slide 321, and second clamping blocks 323 configured on the second clamping arms 322. The second clamping double-sided slide 321 is used to drive the second clamping arm 322 to extend and retract so that the second clamping block 323 clamps or releases the casing side of the single battery cell; The second clamping and fixing plate 314 is also equipped with the limiting component 33, which includes a limiting cylinder 331 and a limiting pressure plate 332; When the first clamping assembly 22 is pulled away from the top cover of the single battery, the limiting cylinder 331 is used to drive the limiting pressure plate 332 to press against the upper part of the housing of the single battery. When the first clamping assembly 22 is pulled away from the cell of the single battery, the limiting cylinder 331 is used to drive the limiting pressure plate 332 away from the upper part of the housing of the single battery.

[0052] In this embodiment, the sliding component 31 can be implemented using the following structure, or it can be implemented using an existing sliding structure, such as a lead screw drive structure. Specifically, with the driving force of the sliding motor 313, the sliding rail 311 is driven to slide laterally relative to the sliding table 312, thereby driving the second clamping component 32 and the limiting component 33 installed through the second clamping fixing plate 314 to slide laterally synchronously.

[0053] The two sides of the second clamping double slide table 321 can be extended and retracted to drive the two second clamping blocks 323 to clamp the narrow sides of the single battery casing, that is, the narrow sides with the center cut; the limiting cylinder 331 provides power to drive the limiting pressure plate 332 to press the upper part of the casing from above.

[0054] When the top cover is removed, the limiting pressure plate 332 needs to press down on the upper part of the housing. With the downward pressure of the limiting pressure plate 332, the battery cell inside the housing is pressed down simultaneously. That is, through the cooperation of the second clamping component 32 and the limiting component 33, the battery cell and the housing are simultaneously restricted on the reference platform 1, so that the first clamping component 22 can remove the top cover. When removing the battery cell, the limiting plate 332 no longer needs to press against the upper part of the housing. This prevents the limiting plate 332 from confining the battery cell inside the housing by pressing against it, which could damage the battery cell or prevent it from being removed from the housing during separation. Instead, the second clamping assembly 32 clamps the housing, and the first clamping assembly 22 clamps the battery cell; the two components working together are sufficient to separate the battery cell from the housing.

[0055] Preferred, such as Figure 11 As shown, it also includes a shell recycling mechanism 4, which is equipped with a receiving box assembly 41, a pushing box assembly 42, a pressing box assembly 43 and a feeding box assembly 44; The junction box assembly 41 includes a junction box cylinder 411 and a junction box plate 412; The junction box cylinder 411 is used to drive the junction box plate 412 to rise and support the housing of the single battery held by the second clamping assembly 32. The push box assembly 42 includes a push box cylinder 421 and a push box plate 422. The push box cylinder 421 is used to drive the push box plate 422 to push the housing of the single battery on the receiving plate 412 to the pressing platform 431. The pressing assembly 43 includes a pressing cylinder 432, a pressing plate 433, and a pressing platform 431. The pressing cylinder 432 is used to drive the pressing plate 433 to flatten the casing of the single battery located on the pressing platform 431. The box feeding assembly 44 includes a box feeding cylinder 441 and a box feeding plate 442. The box feeding cylinder 441 is used to drive the box feeding plate 442 to send the flattened single battery casing on the box pressing table 431 into the recycling bin.

[0056] In this embodiment, after the housing and the battery cell are separated, the second clamping assembly 32 clamps the housing away from the reference platform 1. When the second clamping assembly 32 moves the housing above the receiving plate 412, the receiving cylinder 411 drives the receiving plate 412 to rise and catch the housing, and then lowers to reset. Next, the pushing cylinder 421 drives the pushing plate 422 to push the housing on the receiving plate 412, pushing the housing from the receiving plate 412 to the pressing platform 431. Then, the pressing cylinder 432 drives the pressing plate 433 to press down, causing the pressing plate 433 to flatten the housing on the pressing platform 431. Finally, the feeding cylinder 441 drives the feeding plate 442 to push the flattened housing on the pressing platform 431 into the recycling bin, thereby completing the recycling of the housing.

[0057] Therefore, according to the above description, the working principle of the first clamping and extraction mechanism 2, the second clamping and extraction mechanism 3, and the shell recycling mechanism 4 is as follows: The single battery cell processed by the pouring mechanism 6 is placed on the reference platform 1, with the top cover of the single battery cell facing the first clamping and extraction mechanism 2 and the bottom of the single battery cell shell facing the second clamping and extraction mechanism 3; then, the lifting component 211 adjusts the clamping height of the first clamping component 22 so that the center point of the clamping distance between the two first clamping blocks 223 of the first clamping component 22 is on the same Y-axis as the center point of the width variation of the top cover of the single battery cell; the lateral movement component 212 drives the first clamping component 22 to approach the single battery cell until the top cover is located between the two first clamping blocks 223; the first clamping double-sided slide 221 drives the two first clamping blocks 223 to clamp the narrow edges of the upper and lower sides of the top cover; the sliding component 31 drives the second clamping component 32 to approach the single battery cell until the narrow edges of the single battery cell shell with central slits are located between the two second clamping blocks 323; the second clamping double-sided slide... 321 drives the two second clamping blocks 323 to clamp the narrow edges with central slits on both sides of the housing; then the limiting cylinder 331 drives the limiting pressure plate 332 to descend until the limiting pressure plate 332 lightly presses against the upper part of the housing, so that the limiting pressure plate 332, together with the second clamping assembly 32, restricts the housing of the single battery and the cell inside the housing on the reference platform 1; then the lateral movement assembly 212 drives the first clamping assembly 22 away from the single battery, and the two first clamping blocks 223 clamp the top cover so that it separates from the housing and the cell. Separation of the top cover will simultaneously detach the terminal post and the tab from the battery cell; the lateral movement assembly 212 moves the separated top cover (including the terminal post and the tab) to the top of the collection box. At this time, the push cylinder 231 drives the push plate 232 to extend and push the top cover held by the two first clamping blocks 223 into the collection box. When the push plate 232 pushes the top cover, the two first clamping blocks 223 need to relax their clamping force on the top cover to avoid the push plate 232 failing to push the top cover into the collection box. Thus, the separation and collection of the top cover (including the terminal post and the tab) are completed. It should be noted that the clamping force of the two first clamping blocks 223 on the top cover must be strictly limited within the tensile strength threshold of the tab, and a constant and slow traction force should be applied along the direction of the top cover and the tab to effectively avoid the tab breaking and remaining inside the cell due to excessive pulling force, or the cell electrode being pulled and damaged when the top cover and the tab are pulled out, thereby ensuring the complete removal of the top cover and the tab. During the separation of the top cover from the battery cell, since there are tabs connecting the top cover and the battery cell, as the tabs are pulled away from the battery cell, the battery cell will be exposed from the inside of the housing for a certain distance. The part of the battery cell exposed in the housing provides a clamping position for the next step of clamping the battery cell. In order to ensure that the battery cell can be exposed outside the housing for a certain distance, the limiting pressure plate 332 should not apply excessive pressure to the housing. The pressure applied by the limiting pressure plate 332 should only ensure that the battery cell is not completely pulled away from the housing when the top cover is separated. Next, the lateral movement component 212 drives the first clamping component 22 to approach the single battery cell again, so that the two first clamping blocks 223 clamp the part of the cell exposed in the casing; the sliding component 31 drives the second clamping component 32 away from the reference platform 1, so that the two second clamping blocks 323 of the second clamping component 32 clamp the casing away from the cell, completing the separation of the casing and the cell; since the sliding component 31 drives the second clamping component 32 to apply a continuous and stable linear extraction force along the cell axis, it can effectively overcome the static friction force remaining between the casing and the cell, ensuring that the inner wall of the casing does not scratch or collide with the surface of the cell during the extraction process, protecting the integrity of the cell surface separator; the first clamping component 22 releases the cell, leaving the cell on the reference platform 1, which is then taken away by the robot arm in the next process for further processing; Then, when the two second clamping blocks 323 hold the housing away from the battery cell and move above the receiving plate 412, the receiving cylinder 411 drives the receiving plate 412 to rise, the two second clamping blocks 323 release the housing, the receiving plate 412 receives the housing, and the receiving cylinder 411 drives the receiving plate 412 to descend and reset; after the receiving plate 412 resets, the pushing cylinder 421 drives the pushing plate 422 to extend, pushing the housing on the receiving plate 412 onto the pressing platform 431; the pressing cylinder 432 drives the pressing plate 433 to press down and flatten the housing on the pressing platform 431, and then the feeding cylinder 441 drives the feeding plate 442 to extend, pushing the flattened housing on the pressing platform 431 into the recycling bin.

[0058] On the other hand, this application proposes a method for separating and disassembling a single battery cell from its casing. The method involves using any of the single battery cell and casing separation and disassembly devices described in this application to disassemble the single battery cell after laser cutting. A circumferential slit is formed between the top cover and the casing of the laser-cut single battery cell, and laser-cut central slits are formed on the narrow sides of the casing. The disassembly method includes: Step A: Fix the laser-cut single cell to the slotting table 54, with the center cuts on both sides of the single cell casing facing the pry bar 534 of the prying assembly 53. Step B: Based on the height of the center cut, the prying lifting assembly 52 adjusts the height of the pry bar 534 by lifting to ensure that the first contact surface 5343 and the second contact surface 5344 of the pry bar 534's insert portion 5342 can be inserted into the center cut. The pry slot displacement assembly 51 drives the pry slot assembly 53 to slide along the pry slot groove 541 of the opening table 54 so that the pry piece 534 approaches the center cut and the locking part 5342 of the pry piece 534 is locked into the center cut. The pry bar lifting assembly 52 lifts the pry bar 534. During the lifting process, the rotating part 5341 of the pry bar 534 is driven by the torsional elastic force of the elastic member 5345 to swing the insert part 5342 around the pry bar mounting shaft 533. This causes the insert part 5342 to automatically perform insertion compensation for the insertion into the center cut. After the insert part 5342 can no longer swing down, the pry bar lifting assembly 52 continues to lift, causing the insert part 5342 to continuously output a radial expansion force that acts vertically on the shell wall on both sides of the narrow edge of the shell to widen the center cut. This causes the shell wall to be turned up relative to the center cut, thereby expanding the space between the battery cell and the inside of the shell. During the upward movement of the pry bar 534, if the insert 5342 disengages from the central cut, the insert 5342 will swing back due to inertia under the torsional elastic force of the elastic member 5345. The swinging back motion can cause the insert 5342 to re-insert into the central cut. Step C: Place the single cell after the slits are opened in step B on the flipping table 64, with the center cuts on the narrow sides of the single cell casing facing the flipping single-sided slide table 631 and the top cover facing the receiving upright plate 633. Step D: The flip displacement assembly 61 drives the flip single-sided slide 631 to slide along the flip slide groove 641 of the flip table 64, so that the flip clamp 632 clamps the narrow sides with the center cut on both sides of the single battery casing. The flip motor 621 drives the flip table 64 to flip, so that the top cover and cell of the single battery fall out towards the receiving plate 633 under the action of its own gravity. Synchronously, the single-sided sliding table 631 drives the flipping clamping plate 632 to extend away from the receiving vertical plate 633, clamping the shell and displacing it away from the receiving vertical plate 633. Under the combined force of its own weight and the reverse pulling force of the casing, the top cover of a single battery cell can detach from the casing and the cell can be exposed outside the casing. At this time, most of the cell remains inside the casing. Step E: Place the single cell processed in step D on the reference platform 1, with the top cover of the single cell facing the first clamping and extraction mechanism 2 and the tail of the casing facing the second clamping and extraction mechanism 3. Step F: The lifting assembly 211 lifts the first clamping assembly 22 so that the two first clamping blocks 223 are aligned with the top cover of the single battery cell. The lateral movement assembly 212 drives the first clamping assembly 22 to approach the top cover of the single battery cell so that the top cover of the single battery cell falls between the two first clamping blocks 223. The first clamping double-sided slide 221 drives the two first clamping blocks 223 to clamp the top cover of the single battery cell. Synchronously, the sliding component 31 drives the second clamping component 32 to approach the tail of the single battery casing, so that the narrow edges with central slits on both sides of the single battery casing fall between the two second clamping blocks 323. The second clamping double-sided slide table 321 drives the two second clamping blocks 323 to clamp the single battery casing. The limiting cylinder 331 drives the limiting pressure plate 332 to press against the upper part of the single battery casing. Step G: The second clamping and extraction mechanism 3 remains stationary, and the transverse component 212 drives the first clamping component 22 away from the reference stage 1, so that the first clamping component 22 pulls the top cover of the single battery cell together with the terminal tabs away from the cell. During the process of pulling the top cover away from the cell, the cell is further exposed to the casing. The first clamping assembly 22 clamps the top cover and moves it above the collection box. The push cylinder 231 drives the push plate 232 to extend and push the top cover into the collection box. Step H: The lateral movement component 212 re-drives the first clamping component 22 to approach the cell, so that the two first clamping blocks 223 clamp the part of the cell exposed outside the shell and keep it stationary. The limiting cylinder 331 drives the limiting pressure plate 332 to release the shell. The sliding component 31 drives the second clamping component 32 away from the reference platform 1, so that the second clamping component 32 pulls the single battery shell away from the cell. Step 1: The second clamping assembly 32 clamps the housing and moves it above the receiving plate 412. The receiving cylinder 411 drives the receiving plate 412 to rise to receive the housing and then fall back to its original position. The pushing cylinder 421 drives the pushing plate 422 to push the housing from the receiving plate 412 into the pressing platform 431. The pressing cylinder 432 drives the pressing plate 433 to press down to flatten the housing located on the pressing platform 431. The feeding cylinder 441 drives the feeding plate 442 to push the flattened housing from the pressing platform 431 into the recycling bin.

10. A method for separating and disassembling the cell and casing of a single battery, characterized in that: The cell and casing separation and disassembly device of the single battery as described in any one of claims 1-9 is used to disassemble the single battery after laser cutting. A circumferential slit is formed between the top cover and the casing of the laser-cut single battery, and a central slit is formed on both narrow sides of the casing. The disassembly method includes: Step A: Fix the laser-cut individual cell onto the slit table, with the center cuts on both sides of the narrow edge of the individual cell casing facing the pry bar of the slit assembly. Step B: Based on the height of the center cut, the prying lifting assembly adjusts the height of the pry piece by lifting to ensure that the first and second contact surfaces of the pry piece's insert part can be inserted into the center cut. The prying displacement component drives the prying component to slide along the prying groove of the opening table so that the prying piece is close to the center cut and the locking part of the prying piece is locked into the center cut. The pry bar lifting assembly raises the pry bar. During the rise of the pry bar, its rotating part, under the torsional elastic force of the elastic element, drives the insert part to swing down around the pry bar mounting axis. This causes the insert part to automatically compensate for the insertion into the center cut. After the insert part can no longer swing down, the pry bar lifting assembly continues to raise the pry bar, causing the insert part to continuously output a radial expansion force that acts vertically on the shell walls on both sides of the narrow edge of the shell to widen the center cut. This causes the shell wall to be turned up relative to the center cut, thereby expanding the space between the battery cell and the inside of the shell. If the insert part disengages from the center cut during the lifting process of the pry bar, the insert part will swing back due to inertia under the torsional elastic force of the elastic element. The swing back motion can cause the insert part to re-insert into the center cut. Step C: Place the individual battery cells after the slits are cut in Step B onto the flipping table, with the center slits on both sides of the narrow sides of the individual battery cell casing facing the flipping single-sided slide table and the top cover facing the receiving upright plate. Step D: The flip displacement component drives the flip single-sided slide to slide along the flip groove of the flip table, so that the flip clamping plate holds the narrow sides of the single battery casing with the center cut on both sides. The flip motor drives the flip table to flip, so that the top cover and cell of the single battery fall out towards the receiving plate under the action of its own gravity. Synchronously, the single-sided sliding table drives the flipping clamp to extend away from the receiving vertical plate, clamping the shell and displacing it away from the receiving vertical plate. Under the combined force of its own weight and the reverse pulling force of the casing, the top cover of a single battery cell can detach from the casing and the cell can be exposed outside the casing. At this time, most of the cell remains inside the casing. Step E: Place the single cell processed in step D on the reference platform, with the top cover of the single cell facing the first clamping and extraction mechanism and the tail of the casing facing the second clamping and extraction mechanism. Step F: The lifting assembly raises and lowers the first clamping assembly so that the two first clamping blocks are aligned with the top cover of the single battery cell. The lateral movement assembly drives the first clamping assembly to approach the top cover of the single battery cell so that the top cover of the single battery cell falls between the two first clamping blocks. The first clamping double-sided slide table drives the two first clamping blocks to clamp the top cover of the single battery cell. Synchronously, the sliding component drives the second clamping component to approach the tail of the single battery casing, so that the narrow edges with central slits on both sides of the single battery casing fall between the two second clamping blocks. The second clamping double-sided slide table drives the two second clamping blocks to clamp the single battery casing, and the limiting cylinder drives the limiting pressure plate to press against the upper part of the single battery casing. Step G: The second clamping and extraction mechanism remains stationary, and the lateral movement component drives the first clamping component away from the reference stage, so that the first clamping component pulls the top cover of the single battery cell together with the terminal tabs from the cell. During the process of pulling the top cover from the cell, the cell is further exposed to the casing. The first clamping component clamps the top cover and moves it above the collection box. The push cylinder drives the push plate to extend and push the top cover into the collection box. Step H: The lateral movement component re-drives the first clamping component closer to the cell, so that the two first clamping blocks clamp the part of the cell exposed outside the casing and keep it stationary. The limit cylinder drives the limit pressure plate to release the casing. The sliding component drives the second clamping component away from the reference stage, so that the second clamping component pulls the single battery casing away from the cell. Step 1: The second clamping assembly clamps the housing and moves it above the receiving plate. The receiving cylinder drives the receiving plate to rise to receive the housing and then fall back to its original position. The pushing cylinder drives the pushing plate to push the housing from the receiving plate into the pressing platform. The pressing cylinder drives the pressing plate to press down to flatten the housing on the pressing platform. The feeding cylinder drives the feeding plate to push the flattened housing from the pressing platform into the recycling bin.
