[0042] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0043] like Figures 1 to 6 As shown, the cylindrical battery cell disassembly tool of the present invention includes a positioning sleeve 1, a carrier 2, a cutter 3, a support assembly 4, a sealing ring 5 and a handle 6.

[0044] like Figure 1 and Figure 2 As shown, the positioning sleeve 1 is a cylindrical structure, and the positioning sleeve 1 is used to accommodate cylindrical battery cells; the carrier 2 is arranged on one side of the positioning sleeve 1, and the positioning sleeve 1 is provided with a through slot 101 corresponding to the carrier 2; the cutter 3 is movably arranged on the carrier 2 to selectively enter the positioning sleeve 1 through the through slot 101, or move out of the positioning sleeve 1;

[0045] As shown in the above structure, when disassembling a cylindrical battery cell, one end of the battery cell is placed in the positioning sleeve 1, and then the insertion length of the cylindrical battery cell is adjusted so that the cutter 3 can be aligned with the cutting position of the battery cell shell. Then, the cutter 3 is moved so that the cutter 3 is against the battery cell shell. Then, by rotating the battery cell or the disassembly tool, the battery cell shell can be cut open with the cutter.

[0046] When used, this disassembly tool has the advantage of being easy to operate and can improve the disassembly efficiency. At the same time, since the positioning sleeve 1 accommodates the battery cell, the cutting line is located in the positioning sleeve 1. When the electrolyte splashes, the positioning sleeve 1 will play a protective role to prevent the staff from contacting the electrolyte and prevent the cutter 3 from scratching the staff, thereby effectively improving the safety of disassembly.

[0047] like Figure 1 and Figure 2As shown, the carrier 2 is provided with a receiving groove 201, which is a through structure and corresponds to the through groove 101; the cutter 3 is located in the receiving groove 201;

[0048] As shown in the above structure, the carrier 2 is directly set on the positioning sleeve 1, and a receiving groove 201 is opened corresponding to the through groove 101, so that the cutter 3 can be installed in the receiving groove 201, which makes it convenient to apply driving force to the cutter 3 from one side so that the cutter 3 can be held against the cylindrical battery cell.

[0049] like Figures 3-5 As shown, the support assembly 4 includes a first shaft 41 and a driving member 42, wherein the first shaft 41 is rotatably mounted on the carrier 2; one end of the cutter 3 is connected to the first shaft 41; and the driving member 42 is used to push the other end of the cutter 3 so that the cutter 3 passes through the through slot 101.

[0050] As shown in the above structure, the support assembly 4 is used to support and drive the cutter 3, wherein the first shaft 41 can rotate relative to the carrier 2, and the driving member 42 can apply a thrust to the end of the cutter 3 away from the first shaft 41, so that the cutter 3 and the first shaft 41 rotate synchronously, and then the end edge of the cutter 3 is fitted onto the cylindrical battery cell, thereby realizing the cutting work of the cylindrical battery cell shell.

[0051] like Figure 3 As shown, the driving member 42 includes a second shaft 421 and a threaded rod 422, wherein the second shaft 421 is provided on the carrier 2; the threaded rod 422 passes through the second shaft 421, and the threaded rod 422 and the second shaft 421 are engaged with each other through threads, and the end of the threaded rod 422 corresponds to the other end of the cutter 3;

[0052] As in the above structure, when the cutter 3 is moved, a thrust is applied by the driving member 42;

[0053] Specifically, by rotating the threaded rod 422, the threaded rod 422, in cooperation with the thread of the second shaft 421, will produce axial movement, thereby pushing the cutter 3 to achieve displacement of the cutter 3; in this structure, the threaded rod 422 can effectively control the feed of the cutter 3, thereby controlling the cutting depth to prevent damage to the internal structure of the battery cell, which is conducive to ensuring the integrity of the battery cell disassembly components and ensuring the normal progress of subsequent research and analysis work;

[0054] At the same time, it can effectively prevent the occurrence of puncturing the pole piece and causing the winding core to catch fire, thereby ensuring the safety of disassembly.

[0055] like Figure 3 As shown, the cutter 3 includes a knife holder 31 and a blade 32, wherein one end of the knife holder 31 is connected to the first shaft 41; the blade 32 is detachably connected to the knife holder 31;

[0056] As shown in the above structure, in the structure of the cutter 3, the blade 32 is connected to the blade holder 31, and the blade holder 31 is connected to the first shaft 41. When the threaded rod 422 applies a thrust, the blade holder 31 is pushed, which can prevent the blade 32 from chipping and damage to a certain extent. In order to ensure the cutting effect, the blade 32 and the blade holder 31 are set as a detachable structure to facilitate replacement.

[0057] Specifically, the blade 32 can be fixed to the blade holder 31 in series via screws.

[0058] like Figure 2 As shown, the positioning sleeve 1 includes a cylinder 11 and a ring cover 12, wherein the ring cover 12 is provided at one end of the cylinder 11, and a hole is opened in the middle of the ring cover 12; the carrier 2 is provided on the cylinder 11 near the ring cover 12;

[0059] As shown in the above structure, the positioning sleeve 1 is composed of two parts: a cylinder 11 and a ring cover 12. The cylinder 11 and the ring cover 12 can be set as an integrated structure. When the cylindrical battery cell is disassembled, the pole can extend through the hole in the middle of the ring cover 12, thereby playing a certain positioning role and ensuring the stability of the disassembly work.

[0060] like Figure 5 As shown, the sealing ring 5 is arranged inside the end of the cylinder 11 away from the ring cover 12;

[0061] As shown in the above structure, a sealing ring 5 is provided inside the positioning sleeve 1. The sealing ring 5 is located at the open end of the cylinder 11. When the battery cell is disassembled, after the battery cell is inserted into the cylinder 11, the battery cell shell will abut against the sealing ring 5. If electrolyte overflows during the disassembly process, the electrolyte will be accumulated in the gap between the battery cell and the cylinder 11, which is convenient for subsequent cleaning.

[0062] Specifically, place the disassembly tool and the battery cell on top of the container, then slowly pull out the battery to allow the electrolyte to drip into the container.

[0063] Furthermore, the positioning sleeve 1 is detachably connected to the carrier 2 ; thus, it is convenient to maintain the disassembly tool, especially to replace the cutter 3 .

[0064] like Figure 6 As shown, a boss 21 is provided on the side of the carrier 2, and a connecting seat 13 is provided on the positioning sleeve 1; the boss 21 and the connecting seat 13 are connected by bolts;

[0065] As in the above structure, during installation, the carrier 2 is connected in series with the connecting seat 13 on the positioning sleeve 1 through the boss 21 by bolts. By removing the bolts, the carrier 2, the cutter 3 and the support assembly 4 are easily dismantled, which is beneficial for the maintenance of the cutter 3.

[0066] like Figure 6As shown, the handle 6 is connected with the positioning sleeve 1, and the handle 6 is arranged opposite to the carrier 2;

[0067] As the above structure, in order to improve the safety of the disassembly of the battery cell, the handle 6 is arranged, and the handle 6 is arranged on the side of the positioning sleeve 1 away from the carrier 2, so that the battery cell can be fixed during disassembly, and the handle 6 is held to rotate the disassembly tool, so as to realize the cutting work. In this process, if the electrolyte is sprayed from the accommodating groove 201, it will not splash on the worker, so as to further ensure the disassembly safety.

[0068] Specific implementation steps:

[0069] In application, the battery cell is inserted into the barrel body 11 of the positioning sleeve 1, and then the threaded rod 422 of the driving member 42 is rotated. Under the threaded cooperation of the second shaft 421, the threaded rod 422 moves axially to abut on the cutter 3. The cutter 3 rotates around the first shaft 41 as the center point, and then one end of the cutter 3 abuts on the battery cell. The threaded rod 422 is slowly rotated to control the cutting amount of the cutter 3 on the battery cell. Then, the battery cell or the positioning sleeve 1 is selectively fixed, and the other one is rotated, so as to realize the cutting work on the shell of the battery cell.

[0070] The above only describes the preferred embodiments of the present application, and is not used to limit the present application.
