Technical Field

[0001] The utility model relates to the technical field of battery recycling, in particular to a cutting assembly for a battery module. Background Art

[0002] With the growing number of new energy vehicles, a large number of power batteries in my country will enter the scrap period, so the subsequent cascade utilization of battery cells is imperative. For the cascade utilization or repair of battery cells, the modules in the retired batteries must first be disassembled and reused.

[0003] Most of the existing equipment used in the disassembly process of battery modules is large in size and not convenient for workers to operate, which complicates the overall operation process of the equipment, further increases the risk factor of the operation, and increases the overall maintenance cost of the equipment. Therefore, there is an urgent need for a disassembly device that is easy to operate and safe. Utility Model Content

The electrode piece belongs to the core of the battery module that is fixed on a workbench and exposed. The assembly is characterized in that it includes a mounting base and a cutting mechanism fixed on the mounting base. The mounting base has a through groove with a width that matches the width of the electrode piece.

[0019] 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 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.

[0020] like Figure 1-Figure 3As shown, this embodiment provides a cutting assembly for a battery module, which is used to sequentially cut off multiple parallel connecting pieces 4 vertically welded on the same electrode sheet 2. The electrode sheet 2 belongs to the core of the battery module 1 fixed on the workbench 5 and exposed. It is characterized in that it includes a mounting seat 6 and a cutting mechanism fixed on the mounting seat 6. The mounting seat 6 has a through groove 12 with a width adapted to the width of the electrode sheet 2. When the electrode sheet 2 is adapted to be inserted into the through groove 12, the length direction of the connecting piece 4 is axially perpendicular to the axial direction of the tool 10 of the cutting mechanism.

[0021] By setting a through groove 12 with a width that matches the width of the electrode sheet 2 on the mounting seat 6, the electrode sheet 2 is adapted to be inserted into the through groove 12 during the process of continuous cutting of multiple connecting sheets 4 by the cutting mechanism. As the connecting sheets 4 are cut off one by one, it can be ensured that after some connecting sheets 4 on the electrode sheet 2 are cut off, the electrode sheet 2 will not cause the uncut connecting sheets 4 to be deformed due to imbalance, which can effectively improve the qualified rate of the battery during the cutting and recycling process.

[0022] Compared with the existing technology, while completing the cutting and disassembly of the battery module 1, by setting a through groove 12 compatible with the electrode sheet 2 on the mounting seat 6, the integrity of the cut parts can be guaranteed during the cutting process, which can effectively improve the pass rate of the battery module 1 during the disassembly and cutting process. The overall structure of the equipment is simple and the operation is convenient, which not only reduces the risk factor in the cutting process, but also reduces the overall maintenance cost of the equipment.

[0023] like Figure 1 and Figure 3 As shown, in one embodiment, a walking wheel set is installed at the bottom of the mounting seat 6.

[0024] When cutting the connecting piece 4, by installing a walking wheel group at the bottom of the mounting seat 6, the mounting seat 6 and the cutting mechanism fixed on the mounting seat 6 can be more flexible in the process of moving along the cutting direction, and the workers can save more effort during the cutting process. Secondly, it can also reduce the friction generated when the mounting seat 6 directly contacts the workbench 5, and at the same time reduce the noise generated by the mounting seat 6 during the process.

[0025] In a specific embodiment of the present invention, the traveling wheel assembly is a roller 11 , and the axial direction of the roller 11 is arranged parallel to the axial direction of the tool 10 of the cutting mechanism.

[0026] In another specific embodiment of the present invention, the traveling wheel set may also be a universal wheel or other wheel set capable of traveling, which is not limited here.

[0027] like Figure 1-Figure 2As shown, in one embodiment, the workbench 5 has a first side wall that forms a sliding abutment with the second side wall on the mounting seat 6 when the electrode sheet 2 is adapted to be snapped into the through groove 12, and the second side wall is arranged perpendicular to the axial direction of the tool 10 axis of the cutting mechanism.

[0028] By achieving abutment between the first side wall and the second side wall, the mounting seat 6 can be prevented from deviating from the track while moving along its cutting path during the process of the cutting mechanism cutting the connecting piece 4 in sequence, thereby making the cutting surface of the connecting piece 4 smoother.

[0029] In another specific embodiment of the present invention, a guide wheel group is further provided on the second side wall of the mounting seat 6 and forms a rolling abutment with the first side wall, and the axial direction of the guide wheel group is arranged perpendicular to the axial direction of the tool 10. By installing the guide wheel group on the second side wall, the flexibility of the mounting seat 6 in the process of moving along the cutting direction can be further improved, and the staff can save more effort during the cutting process. Secondly, it can also reduce the friction generated when the mounting seat 6 directly contacts the first side wall, and at the same time, it can further reduce the noise generated by the mounting seat 6 during the process.

[0030] In a specific embodiment of the present invention, the guide wheel group is an auxiliary wheel 13, and the axial direction of the auxiliary wheel 13 is perpendicular to the axial direction of the tool 10 of the cutting mechanism.

[0031] like Figure 1 and Figure 3 As shown, in one embodiment, the mounting seat 6 has a receiving groove, the bottom of which is lower than the bottom of the through groove 12 so that the electrode sheet 2 can fall into the receiving groove by its own weight after being separated from all the connecting sheets 4.

[0032] By setting a storage groove on the mounting seat 6, after completing the cutting process of the connecting piece 4 on the same electrode piece 2, the electrode piece 2 can automatically fall into the storage groove due to the gravity characteristics, and the cutting of the connecting piece 4 and the storage of the electrode piece 2 can be achieved at the same time, which can effectively improve the efficiency of the cutting mechanism during the cutting process and save time and effort.

[0033] like Figure 1 As shown, in one embodiment, when the electrode sheet 2 is fitted into the through slot 12 , the lowest point of the tool 10 is lower than the bottom end of the connecting sheet 4 .

[0034] Specifically, the cutting mechanism includes a driving member 9 fixedly mounted on the mounting seat 6 and a tool 10 fixedly mounted on the power end of the driving member 9. By setting the lowest point of the tool 10 at the bottom end of the connecting piece 4, continuous cutting of the connecting piece 4 can be achieved in the moving direction of the mounting seat 6.

[0035] like Figure 1 and Figure 3As shown, in one embodiment, the receiving groove extends to below the tool 10 .

[0036] By extending the storage groove to the bottom of the tool 10, specifically, the storage groove is composed of a storage area 8 and a dust collection area 7, which can not only store the completed electrode sheet 2 but also collect the metal dust generated by the connecting sheet 4 during the cutting process, thereby preventing the metal dust generated by the connecting sheet 4 during the cutting process from falling directly onto the workbench 5, reducing the work intensity while also reducing the pollution of metal dust to the environment.

[0037] like Figure 1-Figure 2 As shown, in one embodiment, when the electrode sheet 2 is fitted into the through slot 12 , a portion of the connecting sheet 4 between the tool 10 and the electrode sheet 2 abuts against the first top wall of the mounting seat 6 .

[0038] Specifically, as the mounting seat 6 moves in the direction of travel, during the cutting process, the driving member 9 drives the tool 10 to rotate and cuts off multiple parallel arranged connecting pieces 4 in turn. By forming abutment between some connecting pieces 4 and the first top wall on the mounting seat 6, the stability of the connecting piece 4 during the cutting process can be improved, unnecessary shaking of the connecting piece 4 during the cutting process can be avoided, and the flatness of the cutting surface of the connecting piece 4 can be improved.

[0039] like Figure 1-Figure 2 As shown, in one embodiment, when the electrode sheet 2 is fitted into the through slot 12 , part of the connecting sheet 4 between the cutter 10 and the pole 3 of the battery module 1 rests against the second top wall of the mounting seat 6 .

[0040] Specifically, during the cutting process, part of the connecting piece 4 is abutted against the second top wall on the mounting seat 6, which can further improve the stability of the connecting piece 4 during the cutting process, avoid unnecessary shaking of the connecting piece 4 during the cutting process, and further improve the flatness of the cutting surface of the connecting piece 4.

[0041] Of course, it will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, but also encompasses the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and it is intended that all variations that fall within the meaning and range of equivalents of the claims be encompassed within the present invention. Any reference signs in the claims should not be construed as limiting the claim to which they relate.

[0042] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
