When obliquely arranged, the longitudinal plane where the handle is located is parallel to the longitudinal plane where the knife body is located. The oblique arrangement of the handle facilitates one-handed holding by the worker during cutting, and the oblique direction of the handle is generally consistent with the running direction of the disassembling tool, thereby saving manpower.

[0013] Preferably, the disassembling tool has two coaxially arranged cutting knives. The arrangement of the two cutting knives enables the disassembling tool to simultaneously cut two places of the battery shell, thereby facilitating the next step of disassembly.

[0014] Preferably, a fixing member for synchronously rotating the cutting knives is arranged between the two cutting knives.

[0015] Preferably, the height of the knife teeth is 1.4-1.6 mm. The tooth height refers to the distance between the tooth tip and the knife body.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0035] A tool for disassembling aluminum-cased batteries includes a cutting blade for cutting the battery casing, a mounting base for mounting the cutting blade, and a handle 6 disposed above the mounting base. The mounting base includes a top plate and a first side plate 21 and a second side plate 22 extending downwards from opposite sides of the top plate. The upper surface of the top plate serves as a mounting surface for mounting the handle 6. A mounting area for mounting the cutting blade is formed between the first side plate 21 and the second side plate 22.

[0036] The handle 6 can be installed vertically or at an angle. When installed at an angle, the longitudinal plane of the handle 6 is parallel to the longitudinal plane of the blade body 11. The handle length is 150-300mm, and the material has no special requirements. The cutting blade includes a disc-shaped blade body 11 and cutting teeth 12 arranged circumferentially along the disc-shaped blade body 11. The blade body 11 has a central hole, and a mounting shaft 23 is horizontally arranged between the first side plate 21 and the second side plate 22. The blade body 11 is fitted onto the mounting shaft 23 to install the cutting blade. A support member 3 is provided between the blade body 11 and the mounting shaft 23 to ensure that the cutting blade can rotate freely and to prevent wear between the blade body 11 and the mounting shaft 23, thus extending the service life of the disassembly tool. The support member 3 can be a bearing, bushing, etc. The diameter of the disc-shaped blade body 11 is usually not less than 30mm, but the specific diameter depends on the strength of the material used for the blade body 11 and the size of the blade. The cutting teeth 12 include several inclined tooth surfaces and tooth tips formed by the tops of the tooth surfaces.

[0037] To ensure the strength of the cutting blade, the blade body 11 and the cutting teeth 12 are integrally connected and both are made of steel. In this embodiment, there are four teeth, i.e., the teeth have a four-sided pyramidal structure. The height of the cutting teeth 12 is 1.5mm. Since the thickness of aluminum-cased batteries is generally less than 1mm, the 1.5mm tooth height ensures that the internal core of the battery is not damaged while cutting the battery casing. Here, the tooth height refers to the distance between the tooth tip and the blade body 11.

[0038] When disassembling the battery, the worker can hold the handle 6 and push the cutting blade along the seam of the battery casing, causing the cutting blade to rotate along a predetermined trajectory to cut the battery casing. Compared to the slicing cutting method of existing disassembly tools, the rolling cutting method of the cutting blade in this application encounters less resistance during movement, saving manpower. In addition, the force applied by the worker forms a large pressure on the battery casing through the small force-bearing area of ​​the sharp blade teeth 12, which helps to break the aluminum casing more effectively.

[0039] In this embodiment, two cutting blades are disposed in the mounting area. The two cutting blades are connected by a fixing member 4, and both cutting blades are coaxially arranged with the fixing member 4, and are jointly sleeved on the mounting shaft 23. The two cutting blades are connected to the fixing member 4 through a keyway to ensure that the two cutting blades can rotate synchronously. In this embodiment, the fixing member can be a gear. A support member 3 is provided between the blade body 11 of each cutting blade and the mounting shaft 23 to support the cutting blades and ensure that the cutting blades can rotate stably. The distance between the two cutting blades is greater than 5mm. The dual-cutting-blade design can cut two parts of the battery casing at the same time, which is convenient for further disassembly with other tools (such as needle-nose pliers) after breaking the casing, saving time and effort and improving the efficiency of battery disassembly.

[0040] The method of using the aluminum-cased battery disassembly tool disclosed in this embodiment of the utility model is as follows:

[0041] First, place the aluminum-cased battery to be disassembled on a stable workbench and align the double cutting blades with the seam of the battery casing. Then, hold the handle 6 and press down firmly, cutting into the battery casing along the predetermined trajectory, continuing to apply force until it is completely cut open. Finally, use auxiliary tools such as needle-nose pliers to remove the cut part, thus completing the entire disassembly process. Example 2

[0042] The main differences from Example 1 are:

[0043] The horizontally arranged mounting shaft 23 between the first side plate 21 and the second side plate 22 includes a first mounting shaft and a second mounting shaft, wherein the first mounting shaft is mounted on the first side plate 21 and the second mounting shaft is mounted on the second side plate 22, and the two mounting shafts are connected by a coupling.

[0044] The two cutting blades are a first cutting blade near the first side plate 21 and a second cutting blade near the second side plate 22. The first cutting blade is rotatably mounted on a first mounting shaft, and the second cutting blade is rotatably mounted on a second mounting shaft. A fixing member 4 is not required between the two cutting blades. An adjustment assembly is provided between the first side plate 21 and the first cutting blade. The adjustment assembly includes a friction disc 51 mounted on the blade body 11 of the first cutting blade. Two adjusting rods 53 are horizontally arranged on the first side plate 21. One end of each adjusting rod 53 is connected to the friction plate 52, and the other end is screwed with an adjusting member 54. An adjustment assembly is also provided on the second side plate 22 and the second cutting blade. The adjustment assembly includes a friction disc 51 mounted on the blade body of the second cutting blade and two adjusting rods 53 mounted on the second side plate 22. One end of each adjusting rod 53 is connected to the friction plate 52 near the friction disc 51, and the other end is screwed with an adjusting member 53 for controlling the friction between the friction plate 52 and the friction disc 51. The friction plate 52 is close to the friction disk 51. By rotating the adjustment component 54, the friction disk 51 can be brought into contact with the friction plate 52, and the friction between the two can be adjusted. This indirectly controls the rotation speed of the first cutting blade and the second cutting blade, so that the rotation speed of the first cutting blade and the rotation speed of the second cutting blade can be different. This allows the disassembly tool to cut along an arc to avoid damaging part of the battery structure, making the disassembly tool suitable for battery disassembly analysis and recycling work in different situations.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
