Description

Technical Field

[0001] This invention relates to the field of lithium battery technology, and in particular to a lithium battery disassembly device. Background Technology

[0002] As the use of new energy batteries becomes more widespread, the recycling, dismantling, and reuse of these batteries will be a trend. Current recycling and dismantling processes for new energy batteries, especially lithium batteries, are basically mature. These processes include crushing, material sorting, and metal separation. The structure of a lithium battery includes the battery cell and its outer insulating coating.

[0003] In existing technologies, when removing the insulating coating of a lithium battery, a cutting machine is typically used to cut open the four corners of the insulating coating to release stress. Then, the edges of the insulating coating are hammered to deform it. This method has the following problems: 1. Manual hammering is labor-intensive and lacks precision. Because the insulating coating is in close contact with the battery cell, the battery cell is easily damaged in the early stages of hammering, affecting its safety; 2. Hammering the insulating coating requires the hammer to be aimed away from the battery cell. Otherwise, if hammered vertically, the edges will be squeezed into a single piece, resulting in excessive hardness that makes it impossible to pry open the insulating coating and remove the battery cell. However, aiming the hammer away from the battery cell requires precise control of the force, which is very labor-intensive. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a lithium battery dismantling device to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] A lithium battery disassembly device includes a moving mechanism and a disassembly mechanism connected to the moving mechanism. The disassembly mechanism includes a support plate rotatably connected to the moving mechanism, a shielding component and a reciprocating moving component disposed on the support plate, and a striking component connected to the reciprocating moving component. The shielding component is disposed close to the battery cell. The striking component includes a protective shell connected to the reciprocating moving component, a straight chisel and an oblique chisel disposed within the protective shell, and a linkage structure for driving the oblique chisel to move away from the shielding component. The reciprocating moving component is provided with a stroke recognition module for identifying the striking height of the straight chisel. The shielding component includes a shielding plate and a driving structure for driving the shielding plate to move. The driving structure is electrically connected to the stroke recognition module. The driving structure obtains the position of the straight chisel captured by the stroke recognition module and drives the shielding plate to move, so that the shielding plate moves synchronously with the straight chisel.

[0007] According to one aspect of the above technical solution, a first opening is provided at the bottom of the protective shell for the vertical chisel to move. The vertical chisel is connected to the inner wall of the protective shell through an elastic element. The elastic element includes a connecting rod and a spring. One end of the connecting rod is fixedly connected to the inner wall of the protective shell, and the other end is slidably connected to the vertical chisel. The spring is wrapped around the outer cylindrical surface of the connecting rod, and both ends of the spring are fixedly connected to the vertical chisel and the inner wall of the protective shell, respectively.

[0008] According to one aspect of the above technical solution, a pressure sensor is provided in the inner wall of the protective shell at a position relative to the spring, and a limit switch is also provided on the reciprocating motion assembly. The pressure sensor is electrically connected to the limit switch and the stroke recognition module.

[0009] According to one aspect of the above technical solution, the oblique chisel is curved, and the linkage structure includes a first rack fixedly connected to the straight chisel, a first gear meshing with the first rack, and teeth provided on the oblique chisel. The teeth mesh with the first gear, and a second opening for the oblique chisel to move is provided below the protective shell.

[0010] According to one aspect of the above technical solution, the reciprocating moving component includes a slide rod disposed on the support plate, a slider slidably connected to the slide rod, and a hydraulic cylinder disposed in the slider, wherein the slider is fixedly connected to the protective shell.

[0011] According to one aspect of the above technical solution, the moving mechanism includes a first sliding component and a second sliding component arranged vertically, the second sliding component being slidably connected to the first sliding component, and the second sliding component being rotatably connected to the support plate.

[0012] According to one aspect of the above technical solution, a sliding plate is slidably connected to the second sliding component, and the sliding plate is connected to the support plate through a rotating shaft. One end of the rotating shaft is fixedly connected to the support plate, and the other end of the rotating shaft is slidably connected to the sliding plate.

[0013] According to one aspect of the above technical solution, a second gear is sleeved on the rotating shaft, a cylinder is provided on the sliding plate, a second rack is provided inside the sliding plate, the cylinder is fixedly connected to the second rack, and the second rack is meshed with the second gear.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] By setting up a moving mechanism and a disassembly mechanism connected to the moving mechanism, after the four corners of the insulating coating are cut open, the disassembly mechanism can be moved above the insulating coating through the moving mechanism. First, the shielding plate is inserted between the insulating coating and the battery cell through the drive structure. At first, the connection between the insulating coating and the battery cell is very tight, and the shielding plate cannot be fully extended. By activating the reciprocating moving component, the straight chisel is driven to chisel the gap between the insulating coating and the battery cell. Due to the shielding of the shielding plate and the precision of the mechanical equipment, the straight chisel will not damage the battery cell. While the straight chisel is chiseling the gap, the inclined chisel can be driven by the linkage structure to chisel the insulating coating. The inclined action can deform the insulating coating away from the battery cell, preventing the insulating coating from converging due to the straight hammering. This reduces the difficulty for the staff to pry open the insulating coating later and improves work efficiency. Through the linkage of the drive structure and the stroke recognition module, the straight chisel chisels can chisel deeper each time, and the shielding plate will also chisel deeper, improving the protection of the battery cell.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] Please see Figures 1 to 6 The image shows a lithium battery disassembly device according to an embodiment of the present invention, including a moving mechanism 10 and a disassembly mechanism connected to the moving mechanism 10. The disassembly mechanism includes a support plate 20 rotatably connected to the moving mechanism 10, a shielding component 30 and a reciprocating moving component 50 disposed on the support plate 20, and a chisel component 40 connected to the reciprocating moving component 50. The shielding component 30 is disposed close to the battery cell. The chisel component 40 includes a protective shell 41 connected to the reciprocating moving component 50, a straight chisel 42 and an oblique chisel 43 disposed within the protective shell 41. 3. A linkage structure for driving the oblique chisel 43 to move away from the blocking assembly 30. The reciprocating moving assembly 50 is provided with a stroke recognition module for identifying the chiseling height of the straight chisel 42. The blocking assembly 30 includes a blocking plate 31 and a driving structure for driving the blocking plate 31 to move. The driving structure is electrically connected to the stroke recognition module. The driving structure obtains the position of the straight chisel 42 captured by the stroke recognition module and drives the blocking plate 31 to move so that the blocking plate 31 moves synchronously with the straight chisel 42.

[0030] Understandably, this invention, by setting a moving mechanism 10 and a disassembly mechanism connected to the moving mechanism 10, allows the disassembly mechanism to be moved above the insulating coating layer after the four corners of the insulating coating layer are cut open. First, the drive structure inserts the baffle plate 31 between the insulating coating layer and the battery cell. Initially, the connection between the insulating coating layer and the battery cell is very tight, and the baffle plate 31 cannot fully extend. The reciprocating moving assembly 50 drives the vertical chisel 42 to chisel at the gap between the insulating coating layer and the battery cell. Due to the obstruction of the baffle plate 31 and the mechanical equipment... Due to precision considerations, the straight chisel 42 will not damage the battery cell. While the straight chisel 42 is chiseling the gap, the inclined chisel 43 can be driven by the linkage structure to chisel the insulating coating layer. The inclined action can deform the insulating coating layer away from the battery cell, preventing the insulating coating layer from converging due to the straight hammer blow. This reduces the difficulty for workers to pry open the insulating coating layer later and improves work efficiency. Through the linkage of the drive structure and the stroke recognition module, the straight chisel 42 chisels deeper each time, and the shield 31 also chisels deeper, improving the protection of the battery cell.

[0031] Specifically, in this embodiment, a first opening is provided at the bottom of the protective shell 41 for the vertical chisel 42 to move. The vertical chisel 42 is connected to the inner wall of the protective shell 41 by an elastic element, which includes a connecting rod 46 and a spring 45. One end of the connecting rod 46 is fixedly connected to the inner wall of the protective shell 41, and the other end is slidably connected to the vertical chisel 42. The spring 45 surrounds the outer cylindrical surface of the connecting rod 46, and both ends of the spring 45 are fixedly connected to the vertical chisel 42 and the inner wall of the protective shell 41, respectively. A pressure sensor is provided in the inner wall of the protective shell 41 at a position relative to the spring 45. A limit switch is also provided on the reciprocating motion assembly 50. The pressure sensor is electrically connected to the limit switch and the stroke recognition module.

[0032] Understandably, spring 45 is a high-strength spring. During the chisel stroke of the straight chisel 42, spring 45 is also compressed. When spring 45 is compressed, it transmits pressure to the pressure sensor. When the pressure threshold is reached, an electrical signal is sent to the limit switch to lift the protective shell 41 for the next chisel stroke. This prevents excessive chisel pressure and high rigidity of the baffle plate 31, which could damage the battery cell. Therefore, appropriate force must be used for multiple chisels to safely break through the insulating coating. When the pressure sensor sends an electrical signal to the limit switch, it also sends an electrical signal to the stroke recognition module, causing the drive structure to move the baffle plate 31 down before the next chisel stroke to protect it from damage. The drive structure can be implemented using a slide rail cylinder, which is not shown in the figure.

[0033] Furthermore, the oblique chisel 43 is curved, and the linkage structure includes a first rack 47 fixedly connected to the straight chisel 42, a first gear 48 meshing with the first rack 47, and teeth 44 provided on the oblique chisel 43. The teeth 44 mesh with the first gear 48, and a second opening is provided below the protective shell 41 for the oblique chisel 43 to move.

[0034] Understandably, during the chisel stroke of the straight chisel 42, the spring 45 will compress, causing the straight chisel 42 to move upward, which in turn causes the first rack 47 and the first gear 48 to mesh, driving the first gear 48 to rotate. The rotation of the first gear 48 drives the teeth 44 to rotate, causing the oblique chisel 43 to protrude out of the second opening and chisel the insulating coating layer, deforming it in a direction away from the battery core, making it easier for workers to remove the battery core later.

[0035] Furthermore, the reciprocating moving assembly 50 includes a slide rod 52 disposed on the support plate 20, a slider 51 slidably connected to the slide rod 52, and a hydraulic cylinder disposed in the slider 51, wherein the slider 51 is fixedly connected to the protective shell 41.

[0036] Understandably, the hydraulic cylinder is located inside the slider 51, which can drive the slider 51 to reciprocate along the slide rod 52, and use a pressure sensor to determine when to perform the next hammering.

[0037] Furthermore, the moving mechanism 10 includes a first sliding component 11 and a second sliding component 12 arranged vertically. The second sliding component 12 is slidably connected to the first sliding component 11 and rotatably connected to the support plate 20. A sliding plate 61 is slidably connected to the second sliding component 12. The sliding plate 61 is connected to the support plate 20 via a rotating shaft 62. One end of the rotating shaft 62 is fixedly connected to the support plate 20, and the other end of the rotating shaft 62 is slidably connected to the sliding plate 61. A second gear 65 is sleeved on the rotating shaft 62. A cylinder 63 is provided on the sliding plate 61, and a second rack 64 is provided inside the sliding plate 61. The cylinder 63 is fixedly connected to the second rack 64, and the second rack 64 meshes with the second gear 65.

[0038] Understandably, since the insulating coating layer needs to be chiseled open bit by bit, when the disassembly mechanism needs to move laterally, it can be driven by the sliding plate 61 to slide along the second sliding component 12. When the disassembly mechanism needs to move vertically, the second sliding component 12 can be driven to slide along the first sliding component 11. When the edge of the insulating coating layer is reached and the direction needs to be changed, the cylinder 63 drives the second rack 64 to move, so that the second rack 64 drives the second gear 65 to rotate together with the rotating shaft 62, thereby realizing the rotation of the disassembly mechanism.

[0039] In summary, the lithium battery disassembly device in the above embodiments of the present invention, by setting a moving mechanism and a disassembly mechanism connected to the moving mechanism, allows the disassembly mechanism to be moved above the insulating coating layer after the four corners of the insulating coating layer are cut open. First, the drive structure inserts the shielding plate between the insulating coating layer and the battery cell. Initially, the connection between the insulating coating layer and the battery cell is very tight, and the shielding plate cannot fully extend. The reciprocating moving component drives a vertical chisel to chisel through the gap between the insulating coating layer and the battery cell. Due to the shielding effect of the shielding plate, and... Due to the precision limitations of the mechanical equipment, the straight chisel will not damage the battery cell. While the straight chisel is striking the gap, a linkage mechanism can drive an angled chisel to strike the insulation layer. The angled action causes the insulation layer to deform away from the battery cell, preventing the insulation layer from converging due to the straight hammering. This reduces the difficulty for workers to pry open the insulation layer later and improves work efficiency. Through the linkage of the drive mechanism and the stroke recognition module, the straight chisel strikes deeper each time, and the shielding plate also strikes deeper, improving the protection of the battery cell.
