Technical Field

[0002] With the development of science and technology, the performance of lithium batteries has been continuously improved. They have the advantages of high energy density, low self-discharge rate, no memory effect, long cycle life and no pollution. They are widely used in portable electronic devices, electric vehicles, energy storage systems and other fields. Lithium batteries often need to be recycled and disassembled after reaching their service life, so as to improve the secondary utilization rate of some materials.

DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Reference Figures 1 to 5 The present embodiment discloses a lithium battery conveying and disassembling platform, including a rotating table 1 and a plurality of clamping assemblies 2. The rotating table 1 includes a turntable 11 and a cabinet 12. The turntable 11 is rotatably connected to the cabinet 12 through a support shaft. One end of the support shaft is fixedly connected to the output shaft of the reduction motor. The output shaft of the reduction motor drives the support shaft and the turntable 11 to rotate, thereby realizing the station switching on the turntable 11. The reduction motor is fixedly installed in the cabinet 12. A plurality of unloading holes 13 are opened on the turntable 11. The number and position of the unloading holes 13 correspond to the number and position of the clamping assemblies 2 one by one. Inclined grooves 14 are opened on both sides of the unloading holes 13.

[0050] The rotating table 1 also includes at least three groups of limit blocks 15 and a plurality of connecting plates 16, two groups of limit blocks 15 are respectively on both sides of the aluminum shell of the lithium battery, and the other group of limit blocks 15 is distributed on the end cover side of the lithium battery. The limit blocks 15 on both sides of the aluminum shell of the lithium battery are used to limit the aluminum shell of the lithium battery instead of clamping and fixing it. Therefore, the spacing between the limit blocks 15 on both sides of the aluminum shell of the lithium battery is not less than the width of the aluminum shell. The connecting plate 16 is fixedly installed on the turntable 11, and a plurality of guide rods 17 are fixedly installed on the limit blocks 15. The guide rods 17 are slidably connected to the corresponding connecting plates 16. A first threaded rod 18 is rotatably connected to the limit block 15, and the first threaded rod 18 is threadedly matched with the corresponding connecting plate 16. By rotating the handle of the first threaded rod 18, the limit block 15 is driven to slide, and the spacing between the plurality of limit blocks 15 is adjusted, so as to perform position limiting on lithium batteries of different sizes and improve the flexibility of position limiting.

[0051] A plurality of clamping assemblies 2 are distributed on the turntable 11 in a circular array along the axis of the turntable 11. The clamping assemblies 2 include a hydraulic cylinder 21, which is fixedly mounted on the turntable 11. A top plate 22 is fixedly mounted on the output shaft of the hydraulic cylinder 21. The top plate 22 is arranged parallel to the limit block 15 on the end cover side of the lithium battery. The top plate 22 is slidably connected to the turntable 11 through a guide rail. A support plate 23 is rotatably connected below the top plate 22 for controlling the placement angle of the lithium battery. The support plate 23 is located directly above the discharge hole 13 and has a width less than that of the discharge hole 13. A roller 24 is rotatably connected to the support plate 23, and the roller 24 rolls on the turntable 11. An avoidance hole 25 is provided on the top plate 22 for avoiding the knife disc during cutting to avoid knife collision accidents. A support block 19 is fixedly installed at the bottom of the limit block 15 parallel to the top plate 22. When supporting the lithium battery, the upper surface of the support block 19 is flush with the upper surface of the support plate 23 to ensure that the support surfaces of the lithium battery are at the same height. The length of the support block 19 protruding from the limit block 15 is less than the thickness of the lithium battery end cover (or the distance from the cutting line to the end cover surface in the width direction of the lithium battery) to ensure that when the end of the lithium battery away from the support block 19 is detached from the support, the lithium battery falls freely under the action of its own weight and the length of the support block 19 does not interfere with the disassembly process.

[0052] Before placing the lithium battery, the positions of several limit blocks 15 are adjusted, the output shaft of the hydraulic cylinder 21 pushes the top plate 22 to move, and the roller 24 rolls on the turntable 11. At this time, the support plate 23 is perpendicular to the top plate 22, and the distance between the top plate 22 and the limit block 15 on the opposite side is slightly larger than the length of the lithium battery. The lithium battery is placed on the support plate 23 and the support block 19, and the output shaft of the hydraulic cylinder 21 continues to push the top plate 22 to move, so that the top plate 22 and the limit block 15 on the opposite side clamp and fix the lithium battery, thereby realizing the fixing process before disassembly; after the aluminum shell of the lithium battery is disassembled, the separation component 7 drives the separated aluminum shell to move synchronously with the support plate 23 and the top plate 22. After the aluminum shell is completely separated from the battery cell, the separation component 7 is separated from the aluminum shell, and the hydraulic cylinder 21 drives the support plate 23 and the top plate 22 to continue to move backward. When the roller 24 moves to the inclined groove 14, the support plate 23 tilts under the action of gravity, so that the disassembled aluminum shell slides from the discharge hole 13, thereby realizing the automatic unloading process.

[0053] It should be noted that the length of the support plate 23 is long enough. When the support block 19 does not exist and the lithium battery is supported only by the support plate 23, the lithium battery can still be stably placed on the support plate 23, reducing the difficulty of early positioning and clamping.

[0054] Ginseng Figure 1 , Figure 2 and Figure 6 Two groups of first dual-axis manipulators 3 are fixedly installed on the cabinet 12, and the two groups of first dual-axis manipulators 3 are symmetrically distributed about the central plane of the upper and lower surfaces of the support platform of the cabinet 12. The first dual-axis manipulator 3 includes a first fixed frame 31, and the first fixed frame 31 is fixedly installed on the cabinet 12. A first telescopic cylinder 32 is fixedly installed on the first fixed frame 31, and a first sliding frame 33 is fixedly installed on the output shaft of the first telescopic cylinder 32. The first sliding frame 33 is slidably connected to the first fixed frame 31 through a guide rail, and a second telescopic cylinder 34 is fixedly installed on the first sliding frame 33, and the output shaft of the second telescopic cylinder 34 is fixedly connected to the first adjusting frame 35, and a cutting machine 6 is fixedly installed on the first adjusting frame 35. A first positioning plate 36 is fixedly mounted on the first sliding frame 33, and the first adjusting frame 35 passes through the first positioning plate 36 and is slidably connected to the first positioning plate 36. The first positioning plate 36 can effectively improve the stability of the first adjusting frame 35 of the corresponding cutting machine 6 during cutting, and reduce the risk of deformation, etc. The two groups of first dual-axis manipulators 3 and the corresponding cutting machines 6 constitute a first disassembly assembly, which is used for cutting and disassembling the upper and lower surfaces of the aluminum shell of the lithium battery in the width direction. The first telescopic cylinder 32 adjusts the corresponding cutting machine 6 to move in the width direction of the aluminum shell and forms a cutting line during cutting. The cutting line is parallel to the placement plane of the lithium battery, and the second telescopic cylinder 34 adjusts the cutting depth of the corresponding cutting machine 6 on the aluminum shell.

[0055] Reference Figure 2 and Figure 7A second disassembly component 4 is fixedly installed on the cabinet 12, and the second disassembly component 4 includes a second fixed frame 41, two groups of second dual-axis manipulators and two groups of cutting machines 6. The second fixed frame 41 is fixedly installed on the cabinet 12; the second dual-axis manipulator includes a third telescopic cylinder 42, and the third telescopic cylinder 42 is fixedly installed on the second fixed frame 41. The output shaft of the third telescopic cylinder 42 is fixedly connected with a second sliding frame 43, and the second sliding frame 43 is slidably connected to the second fixed frame 41 through a guide rail. A fourth telescopic cylinder 44 is fixedly installed on the second sliding frame 43, and the output shaft of the fourth telescopic cylinder 44 is fixedly connected with a second adjusting frame 45. The cutting machine 6 is fixedly installed on the bottom of the corresponding second adjusting frame 45, and a second positioning plate 46 is fixedly installed on the second sliding frame 43. The second adjusting frame 45 passes through the second positioning plate 46 and is slidably connected to the second positioning plate 46.

[0056] The third telescopic cylinder 42 of the second dual-axis manipulator adjusts the cutting depth of the corresponding cutter 6 and the side of the lithium battery, and the fourth telescopic cylinder 44 pushes the corresponding cutter 6 to move up and down, cuts the side of the lithium battery and forms a cutting line, and the cutting line is perpendicular to the placement plane of the lithium battery; the first disassembly assembly and the second disassembly group form a cutting surface after the lithium battery cutting line, so that the end cover and the aluminum shell of the lithium battery are separated, which is convenient for the subsequent separation of the battery cell and the aluminum shell.

[0057] Ginseng Figure 1 , Figure 2 and Figure 8 A third disassembly assembly 5 is fixedly installed on the cabinet 12, and the third disassembly assembly 5 includes a third fixed frame 51, two groups of third dual-axis manipulators and two groups of cutting machines 6. The third fixed frame 51 is fixedly installed on the cabinet 12; the third dual-axis manipulator includes a fifth telescopic cylinder 52, and the fifth telescopic cylinder 52 is fixedly installed on the third fixed frame 51. The output shaft of the fifth telescopic cylinder 52 is fixedly connected with a third sliding frame 53. The third sliding frame 53 is slidably connected to the third fixed frame 51 through a guide rail. A sixth telescopic cylinder 54 is fixedly installed on the third sliding frame 53, and the output shaft of the sixth telescopic cylinder 54 is fixedly linked with a third adjusting frame 55. The cutting machine 6 is fixedly installed at the bottom of the corresponding third adjusting frame 55. The fifth telescopic cylinder 52 of the third dual-axis manipulator is used to adjust the cutting depth of the side of the aluminum shell of the lithium battery. The cutting line is parallel to the supporting surface of the lithium battery and is perpendicular to the cutting surface formed by the first disassembly component and the second disassembly component 4. The cutting line formed by the third disassembly component 5 on the aluminum shell can effectively reduce the tightening force of the aluminum shell on the end cover and the battery cell, and reduce the difficulty of subsequent separation of the end cover or the battery cell from the aluminum shell.

[0058] The cutting machine 6 is composed of a cutting disc, a motor and a drive box. The motor is used to drive the cutting disc to rotate in height to cut the lithium battery. The drive box is used to support and protect the motor. The cutting machine 6 is fixedly installed with the corresponding adjustment frame of the first disassembly component, the second disassembly component 4 or the third disassembly component 5 through the drive box. The cutting machine 6 is an existing mature equipment and will not be described in detail here.

[0059] Ginseng Figure 1 , Figure 2 and Figures 9 to 12 The separation component 7 includes a fourth fixed frame 71, which is fixedly mounted on the cabinet 12, a seventh telescopic cylinder 72 is fixedly mounted on the fourth fixed frame 71, an output shaft of the seventh telescopic cylinder 72 is fixedly connected to a fourth sliding frame 73, the fourth sliding frame 73 is slidably connected to the fourth fixed frame 71 through a guide rail, an eighth telescopic cylinder 74 is fixedly mounted on the fourth sliding frame 73, and an output shaft of the eighth telescopic cylinder 74 is fixedly connected to a fourth adjusting frame 75, two groups of first limit assemblies 76 are installed on the fourth adjusting frame 75, and the two groups of first limit assemblies 76 are distributed on both sides of the lithium battery, a fifth adjusting frame 77 is fixedly and slidably connected to the fourth sliding frame 73, a second threaded rod 78 is rotatably connected to the fifth adjusting frame 77, and the second threaded rod 78 is threadedly matched with the fourth sliding frame 73, and two groups of second limit assemblies 79 are installed on the fifth adjusting frame 77, and the two groups of second limit assemblies 79 are distributed on both sides of the lithium battery. The second threaded rod 78 is rotated to drive the fifth adjustment frame 77 to slide on the fourth sliding frame 73, thereby adjusting the relative position of the second limiting assembly 79 and the lithium battery.

[0060] The first limit assembly 76 includes a ninth telescopic cylinder 761, which is fixedly mounted on the fourth adjustment frame 75. The output shaft of the ninth telescopic cylinder 761 is fixedly mounted with a push plate 762, and a clamping plate 763 is mounted on the push plate 762. The clamping plate 763 is slidably connected to the push plate 762 through a guide column 764. An elastic member is mounted on the guide column 764, one end of the elastic member is fixedly connected to the push plate 762, and the other end is fixedly connected to the clamping plate 763. A third positioning plate 765 is fixedly mounted on the clamping plate 763. The thickness of the third positioning plate 765 is less than the height of the cutting seam, thereby ensuring that the third positioning plate 765 can be inserted into the cutting seam. The third positioning plate 765 has a certain length in the length direction of the cutting seam, thereby ensuring the strength of the third positioning plate 765 during operation and reducing the risk of breakage. A groove is provided on the side of the clamping plate 763 close to the center line of the push plate 762, and the third positioning plate 765 slidably cooperates with the groove.

[0061] The only difference between the second limiting assembly 79 and the first limiting assembly 76 is that the ninth telescopic cylinder 761 on the second limiting assembly 79 is fixedly mounted on the fifth adjusting frame 77, the push plate 762 on the second limiting assembly 79 is slidably connected to the fifth adjusting frame 77, and the clamping plates 763 on the second limiting assembly 79 and the first limiting assembly 76 are on the opposite side of the third positioning plate 765 (i.e., the sliding connection is on the opposite side of the third positioning plate 765), thereby satisfying the clamping and positioning requirements at both ends of the cutting seam of the lithium battery.

[0062] The seventh telescopic cylinder 72 drives the first limiting assembly 76 and the second limiting assembly 79 to rise and fall, so that the third positioning plate 765 is aligned with the cutting seam. The ninth telescopic cylinder 761 on the first limiting assembly 76 pushes the clamping plate 763 to press against the tail end of the lithium battery aluminum shell. When the clamping plate 763 contacts the aluminum shell, the elastic member is compressed, and the ninth telescopic cylinder 761 continues to push to insert the third positioning plate 765 into the cutting seam. Similarly, the ninth telescopic cylinder 761 on the second limiting assembly 79 pushes the clamping plate 763 to press against the end cover of the lithium battery, and the corresponding third positioning plate 765 is inserted into the cutting seam. No more details are given here. After the aluminum shell and the end cover of the lithium battery are clamped and positioned respectively, the top plate 22 moves backward under the drive of the hydraulic cylinder 21, and the output shaft of the eighth telescopic cylinder 74 synchronously drives the first limiting assembly 76 to move toward the side of the top plate 22, thereby realizing the separation of the aluminum shell and the battery cell (the battery cell and the end cover are fixed).

[0063] By setting the clamping plate 763 and the third positioning plate 765, the stability of the separation of the aluminum shell and the battery cell can be effectively improved, and the separation efficiency can be improved. After the separation is completed, when the first limit assembly 76 and the second limit assembly 79 are separated from the lithium battery, the ninth telescopic cylinder 761 drives the third positioning plate 765 to separate from the cutting seam first. At this time, the clamping plate 763 still has the clamping force, thereby preventing the separated lithium battery aluminum shell or end cover from following the movement of the third positioning plate 765, and avoiding the problem of incomplete cancellation of positioning. When the telescopic cylinder of the ninth telescopic cylinder 761 is recovered again, the third positioning plate 765 is separated from the lithium battery, and the aluminum shell and battery cell of the lithium battery automatically fall from the unloading hole 13 into the corresponding collection box in the cabinet 12, realizing the automatic unloading process.

[0064] It should be noted that if Fig.10 As shown, when the third disassembly component 5 decomposes and cuts the side of the aluminum shell of the lithium battery, its cutting line does not pass through the rear end of the aluminum shell, thereby providing a positioning point for the third positioning plate 765 when separating the aluminum shell, ensuring that the third positioning plate 765 has a control point that can be pulled.

[0065] When a lithium battery conveying and disassembling platform disclosed in an embodiment of the present invention is used, the positions of the plurality of limit blocks 15 are adjusted, the output shaft of the hydraulic cylinder 21 pushes the top plate 22 to move, and the roller 24 rolls on the turntable 11. At this time, the support plate 23 is perpendicular to the top plate 22, and the distance between the top plate 22 and the limit blocks 15 on the opposite side is slightly larger than the length of the lithium battery. The lithium battery is placed on the support plate 23 and the support block 19, and the output shaft of the hydraulic cylinder 21 continues to push the top plate 22 to move, so that the top plate 22 and the limit blocks 15 on the opposite side clamp and fix the lithium battery.

[0066] The rotating table 1 drives the fixed lithium battery to move to the next station, the first disassembling assembly cuts the upper and lower surfaces of the lithium battery once, the rotating table 1 drives the lithium battery cut once to move to the next station, the second disassembling assembly 4 cuts the lithium battery twice, the secondary cutting line and the primary cutting line form a cutting surface, so that the end cover of the lithium battery (the battery cell and the end cover are fixedly connected) are separated from the aluminum shell, the rotating table 1 drives the lithium battery cut twice to move to the next station, the third disassembling assembly 5 cuts the side wall of the aluminum shell to reduce the clamping force of the aluminum shell on the battery cell, and the rotating table 1 drives the lithium battery cut thrice to move to the next station;

[0067] The seventh telescopic cylinder 72 drives the first limiting assembly 76 and the second limiting assembly 79 to descend, so that the third positioning plate 765 is aligned with the cutting slit, and the ninth telescopic cylinder 761 on the first limiting assembly 76 pushes the clamping plate 763 to press against the tail end of the lithium battery aluminum shell. When the clamping plate 763 contacts the aluminum shell, the elastic member is compressed, and the ninth telescopic cylinder 761 continues to push to insert the third positioning plate 765 into the cutting slit; similarly, the ninth telescopic cylinder 761 on the second limiting assembly 79 pushes the clamping plate 763 to press against the end cover of the lithium battery, and the corresponding third positioning plate 765 is inserted into the cutting slit;

[0068] After the lithium battery aluminum shell and the end cover are clamped and positioned respectively, the top plate 22 moves backward under the drive of the hydraulic cylinder 21, and the output shaft of the eighth telescopic cylinder 74 simultaneously drives the first limit assembly 76 to move toward the top plate 22, so that the aluminum shell and the battery cell are gradually separated;

[0069] When the aluminum shell is completely separated from the battery cell, the separation component 7 is reset and separated from the aluminum shell, and the battery cell falls from the unloading hole 13 under the action of gravity. The hydraulic cylinder 21 drives the support plate 23 and the top plate 22 to continue to move backward. When the roller 24 moves to the inclined groove 14, the support plate 23 tilts under the action of gravity, so that the disassembled aluminum shell slides from the unloading hole 13, completing the automatic unloading process.

[0070] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
