[0047] From the development of market situation, the application of battery is more and more extensive. The battery is not only applied to the energy storage power supply system of hydropower, thermal power, wind power and solar power station, but also widely applied to electric bicycles, electric motorcycles, electric vehicles and other electric vehicles, military equipment, aerospace and other fields. With the continuous expansion of the application field of the battery, the market demand is also increasing, and the safety performance of the battery is required to be higher and higher. In order to improve the safety performance of the battery, it is necessary to conduct all-round test verification on the safety performance of the battery in the product development process.

[0048] The traditional verification method usually includes overcharge, overdischarge, short circuit, extrusion, needle puncture and other test items. However, the traditional verification method cannot cover the extreme harsh working condition scenes of the market side. For example, the working condition of cutting the battery, the working condition of causing serious structural damage to the battery by collision or serious scratching, and even the working condition of causing structural damage to the battery. The battery products tested and verified by the above test will still have various safety problems after being put on the market.

[0049] In order to cut the battery, a cutting device needs to be used to cut the battery. However, the battery may catch fire and explode during cutting or sawing. The cutting device in the related art is not suitable for the working condition scene of cutting the battery, cannot resist the energy when the battery catches fire and explodes, and is easy to damage.

[0050] Based on the above considerations, this application designs a battery cutting device, incorporating a safety protection structure to safeguard easily damaged functional components within the cutting equipment. This design reduces the damage to the battery cutting device caused by battery fires or explosions, making the device suitable for battery cutting tests and addressing the issue that battery safety performance tests cannot cover extremely harsh operating conditions.

[0051] The battery cutting device disclosed in this application can be used for battery safety performance testing. The battery can be a secondary battery or a primary battery; it can also be a lithium-ion battery, a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited to these. The battery can be cylindrical, flat, cuboid, or other shapes, meaning it is not limited to prismatic batteries; it can also be cylindrical batteries, etc.

[0052] According to some embodiments of this application, refer to Figures 1 to 5 , Figure 1 A three-dimensional structural schematic diagram of the battery cutting device in some embodiments of this application is shown. Figure 2 This illustration shows a three-dimensional structural diagram of the battery cutting device in some embodiments of this application from another perspective. Figure 3 A top view of a battery cutting device according to some embodiments of this application is shown. Figure 4 A rear view of a battery cutting device according to some embodiments of this application is shown. Figure 5 Cross-sectional views of a battery cutting apparatus according to some embodiments of this application are shown. This application provides a battery cutting apparatus 100. The battery cutting apparatus 100 includes a cutting mechanism 1, a feeding mechanism 2, a first protective member 3, and a second protective member 4. The cutting mechanism 1 includes a cutting member 11 and a first driving member 12, the cutting member 11 being connected to the first driving member 12, and the first driving member 12 driving the cutting member 11 to perform cutting. The feeding mechanism 2 includes a clamping assembly 21 and a second driving member 22, the clamping assembly 21 being used to clamp the battery, and the second driving member 22 being connected to the clamping assembly 21 and used to drive the clamping assembly 21 to move along a first direction, the first direction being parallel to the cutting direction of the cutting member 11, and the enclosed area 210 of the orthographic projection of the clamping assembly 21 onto a plane perpendicular to the first direction intersects with the orthographic projection of the cutting member 11 onto a plane perpendicular to the first direction. The first protective member 3 is at least disposed on the side of the first driving member 12 near the cutting member 11. The second protective member 4 is at least disposed on the side of the second driving member 22 near the clamping assembly 21 and the cutting member 11.

[0053] like Figures 1 to 5 As shown, the X direction represents the first direction, the Z direction represents the second direction, and the Y direction represents the third direction. In some embodiments, the X, Y, and Z directions are perpendicular to each other.

[0054] The cutting member 11 is used for cutting the battery. The cutting direction of the cutting member 11 refers to the relative movement direction between the cutting member 11 and the battery when the cutting member 11 cuts the battery. The cutting member 11 can be in a sheet shape, such as a circular saw blade, a sheet-shaped cutter, a saw blade, or a blade, etc. The cutting member 11 can also be in other structures, such as a wire shape or a chain shape, etc.

[0055] The first driving member 12 can drive the cutting member 11 to rotate for cutting. The cutting member 11 rotates to form a cutting surface. The cutting surface of the cutting member 11 is perpendicular to the rotation axis of the cutting member 11. At this time, the cutting direction of the cutting member 11 is parallel to the cutting surface of the cutting member 11. The first driving member 12 can also drive the cutting member 11 to linearly move for cutting. For example, the cutting member 11 can linearly reciprocate. At this time, the cutting direction of the cutting member 11 intersects with the linear movement direction of the cutting member 11. For example, the cutting direction of the cutting member 11 can be perpendicular to the linear movement direction of the cutting member 11. The first driving member 12 can be a motor, or other power devices, such as an internal combustion engine, a hydraulic motor, a pneumatic motor, etc.

[0056] The clamping assembly 21 is used for clamping and fixing the battery. The second driving member 22 drives the clamping assembly 21 to move along the first direction, so that the clamping assembly 21 can drive the battery to move along the first direction. The second driving member 22 can be a motor, or other power devices, such as an internal combustion engine, a hydraulic cylinder, a pneumatic cylinder, etc.

[0057] When the battery is clamped on the clamping assembly 21, the orthographic projection of the battery on a plane perpendicular to the first direction is located in the enclosed area 210 of the orthographic projection of the clamping assembly 21 on the plane perpendicular to the first direction. Since the enclosed area 210 of the orthographic projection of the clamping assembly 21 on the plane perpendicular to the first direction intersects with the orthographic projection of the cutting member 11 on the plane perpendicular to the first direction, when the battery is clamped on the clamping assembly 21, the orthographic projection of the battery on the plane perpendicular to the first direction intersects with the orthographic projection of the cutting member 11 on the plane perpendicular to the first direction. In this way, the battery can move along the first direction to pass through the cutting member 11 and contact the cutting member 11. At the same time, since the cutting direction of the cutting member 11 is parallel to the first direction, when the battery moves to pass through the cutting member 11, the cutting member 11 can cut the battery.

[0058] When the battery cutting device 100 is used, the battery to be cut is clamped and fixed on the clamping assembly 21, and the battery to be cut and the cutting member 11 are arranged opposite to each other along the first direction. The first driving member 12 drives the cutting member 11 to cut. At the same time, the second driving member 22 drives the clamping assembly 21 to move along the first direction to approach the cutting member 11. The clamping assembly 21 drives the battery to move along the first direction to approach the cutting member 11. When the battery moves to pass through the cutting member 11, the cutting member 11 cuts the battery. In this way, the battery cutting device 100 can be used for cutting test of the battery.

[0059] The first protection member 3 is located on the side of the first driving member 12 close to the cutting member 11, that is, the cutting member 11 is located on the other side of the first protection member 3. The first protection member 3 separates the installation area of the first driving member 12 from the cutting operation area of the cutting member 11, which can protect the first driving member 12 and reduce the damage of the first driving member 12 caused by the out-of-control fire and explosion of the battery when the battery is cut. The first protection member 3 can be made of, but is not limited to, an explosion-proof steel plate.

[0060] The second protection member 4 is located on the side of the second driving member 22 close to the clamping assembly 21 and the cutting member 11, that is, the cutting member 11 and the clamping assembly 21 are located on the other side of the second protection member 4. The second protection member 4 separates the installation area of the second driving member 22 from the cutting operation area of the cutting member 11, which can protect the second driving member 22 and reduce the damage of the second driving member 22 caused by the out-of-control fire and explosion of the battery when the battery is cut. The second protection member 4 can be made of, but is not limited to, an explosion-proof steel plate.

[0061] The battery cutting device 100 of the embodiment can reduce the damage of the first driving member 12 and the second driving member 22 caused by the out-of-control fire and explosion of the battery when the battery is cut, reduce the probability of damage of the battery cutting device 100 caused by the fire and explosion of the battery, and make the battery cutting device 100 applicable to cutting test of the battery, thereby solving the problem that the battery safety performance test cannot cover extreme harsh working condition scenes.

[0062] In some embodiments, referring to Figure 1 and Figure 5 , the battery cutting device 100 further comprises a liquid collecting mechanism 5, and the liquid collecting mechanism 5 comprises a receiving member 51 arranged below the cutting member 11.

[0063] After the battery is cut and the fire and explosion occur, the high-temperature electrolyte of the combustion will flow out of the battery, and the flowed electrolyte will drop downward along the gravity direction. The below of the cutting member 11 refers to the below of the cutting member 11 along the gravity direction. Arranging the receiving member 51 below the cutting member 11 along the gravity direction can make the flowed electrolyte in the process of cutting the battery by the cutting member 11 fall on the receiving member 51, so that the receiving member 51 can receive the flowed electrolyte when the battery is cut. The receiving member 51 can be plate-shaped, such as an inclined plate or an arc-shaped plate, etc. The receiving member 51 can also be other shapes, such as a groove shape or a funnel shape, etc.

[0064] In some embodiments, the liquid collection mechanism 5 may further include a collection container 52, which may be located below the receiving member 51. "Below the receiving member 51" refers to the area below the receiving member 51 along the direction of gravity. By positioning the collection container 52 below the receiving member 51 in the direction of gravity, the electrolyte received by the receiving member 51 can flow into the collection container 52, which is used to collect the electrolyte for centralized processing. The collection container 52 may be, but is not limited to, a box-shaped or trough-shaped container.

[0065] In some embodiments, the receiver 51 may have a drain outlet 511, through which the electrolyte received by the receiver 51 can flow out in a concentrated manner. A collection container 52 is positioned below the drain outlet 511 of the receiver 51 along the direction of gravity. This improves collection efficiency and simplifies the structure of the receiver 51 and the collection container 52.

[0066] In some embodiments, the orthographic projection of the cutting element 11 onto a plane perpendicular to the direction of gravity (i.e., a horizontal plane) falls within the coverage area of ​​the orthographic projection of the receiving element 51 onto a plane perpendicular to the direction of gravity. This increases the probability that the electrolyte flowing out during the cutting process will fall onto the receiving element 51, reducing electrolyte leakage.

[0067] By setting up a liquid collection mechanism 5, the electrolyte flowing out during the battery cutting process can be collected, making it convenient to centrally process the electrolyte and reducing damage to the battery cutting device 100 and environmental pollution caused by the electrolyte.

[0068] In some embodiments, refer to Figures 1 to 6 , Figure 6 An exploded view of a battery cutting apparatus 100 according to some embodiments of this application is shown. The battery cutting apparatus 100 further includes a mounting mechanism 6, which includes a mounting member 61 having a first side 611 and a second side 612 disposed opposite to each other along a second direction intersecting the first direction. At least a portion of the cutting member 11 is disposed on the first side 611 of the mounting member 61. A clamping assembly 21 is disposed on the first side 611 of the mounting member 61.

[0069] Mounting mechanism 6 serves as the mounting base for battery cutting device 100. Cutting mechanism 1, feeding mechanism 2, first protective member 3, second protective member 4, and liquid collection mechanism 5 can be mounted on mounting mechanism 6. Mounting member 61 can be used to movably mount clamping assembly 21. The second direction can be the thickness direction of mounting member 61. In some embodiments, the first direction can be parallel to the surface of the first side 611 of mounting member 61. Mounting member 61 can be plate-shaped, such as a rectangular plate; mounting member 61 can also have other structures. Mounting member 61 can be, but is not limited to, made of explosion-proof steel plate.

[0070] The cutting member 11 can be located entirely on the first side 611 of the mounting member 61, or can be located partly on the first side 611 of the mounting member 61 and partly on the second side 612 of the mounting member 61. Since the clamping assembly 21 is movably arranged on the first side 611 of the mounting member 61, the cutting operation area of the cutting member 11 is located on the first side 611 of the mounting member 61.

[0071] In this way, the mounting member 61 can support the movement of the clamping assembly 21, improve the stability of the movement of the clamping assembly 21, and further improve the cutting accuracy of the cutting member 11 on the battery, thereby improving the test effect of the cutting test on the battery.

[0072] In some embodiments, with reference to Figure 2 , Figures 4 to 6 The first driving member 12 is arranged on the second side 612 of the mounting member 61. Part of the cutting member 11 is arranged on the second side 612 of the mounting member 61 and connected with the first driving member 12. The first protective member 3 includes a first protective wall 31 connected to the second side 612 of the mounting member 61 and shielding a side of the first driving member 12 close to the cutting member 11.

[0073] Since the cutting operation area of the cutting member 11 is located on the first side 611 of the mounting member 61, and the first driving member 12 is arranged on the second side 612 of the mounting member 61, the mounting member 61 can isolate the first driving member 12 from the cutting operation area of the cutting member 11. The part of the cutting member 11 located on the second side 612 of the mounting member 61 is connected with the first driving member 12, so that the first driving member 12 drives the cutting member 11 to perform cutting movement.

[0074] The first protective wall 31 shields a side of the first driving member 12 close to the cutting member 11, which means that the projection of the first protective wall 31 on the cutting member 11 along the direction in which the first driving member 12 points to the cutting member 11 covers the projection of the first driving member 12 on the cutting member 11 along the direction in which the first driving member 12 points to the cutting member 11. The first protective wall 31 cooperates with the mounting member 61 to divide the space on the second side 612 of the mounting member 61 into a mounting area of the first driving member 12 and a mounting area of the cutting member 11, thereby isolating the first driving member 12 from the cutting member 11 and the clamping assembly 21. The first protective wall 31 can be, but is not limited to, a plate, such as a flat plate or an arc-shaped plate. The first protective wall 31 can be made of, but is not limited to, an explosion-proof steel plate. The first protective wall 31 can reduce the influence of the battery fire and explosion on the first driving member 12 when the cutting member 11 cuts the battery, and can also block the splashing of the electrolyte to the first driving member 12, thereby achieving protection of the first driving member 12.

[0075] Thus, the first protective wall 31 cooperates with the mounting member 61 to isolate the first driving member 12 from the cutting member 11 and the clamping assembly 21, thereby protecting the first driving member 12 and reducing the damage of the first driving member 12 caused by the battery explosion and the electrolyte flowing out of the battery during the cutting of the battery by the cutting member 11, and improving the safety of the battery cutting test. Moreover, the structure is simple, and the cost can be reduced.

[0076] In some embodiments, with reference to Figure 1 , Figure 2 , Figures 4 to 6 The first protective member 3 further comprises at least one of a second protective wall 32, a third protective wall 33 and a fourth protective wall 34. The second protective wall 32 is connected to one end of the first protective wall 31 away from the mounting member 61 and is located on the side of the first protective wall 31 facing or away from the cutting member 11. The third protective wall 33 is connected to at least one side edge of the first protective wall 31 adjacent to the mounting member 61 and is located on the side of the first protective wall 31 facing or away from the cutting member 11. The fourth protective wall 34 is connected to the second side 612 of the mounting member 61 and blocks the side of the cutting member 11 away from the first protective wall 31.

[0077] The first protective member 3 can comprise the second protective wall 32. The second protective wall 32 can be connected to the side of the first protective wall 31 facing the cutting member 11, and the first protective wall 31, the second protective wall 32 and the mounting member 61 cooperatively enclose the mounting area of the cutting member 11. Thus, the second protective wall 32 can block the cutting member 11 in the direction away from the mounting member 61, thereby reducing the influence of the battery explosion and the electrolyte flowing out of the battery during the cutting of the battery by the cutting member 11 on the external environment, reducing environmental pollution and improving the safety of the battery cutting test. The second protective wall 32 can also be connected to the side of the first protective wall 31 away from the cutting member 11 (i.e. the side of the first protective wall 31 facing the first driving member 12), and the first protective wall 31, the second protective wall 32 and the mounting member 61 cooperatively enclose the mounting area of the first driving member 12. Thus, the protection effect of the first driving member 12 can be improved, and the damage of the first driving member 12 can be reduced. The second protective wall 32 can be but is not limited to a plate, such as a flat plate or an arc-shaped plate. The second protective wall 32 can be but is not limited to made of an explosion-proof steel plate.

[0078] The first protective member 3 can also comprise a third protective wall 33. The third protective wall 33 can be connected to the first protective wall 31 at one side adjacent to the mounting member 61, or can be connected to the first protective wall 31 at two opposite sides adjacent to the mounting member 61. The third protective wall 33 can be connected to the side of the first protective wall 31 facing the cutting member 11, so that the first protective wall 31, the third protective wall 33 and the mounting member 61 cooperatively define a mounting area of the cutting member 11. In this way, the third protective wall 33 can further shield the cutting member 11, and can reduce the influence of the battery fire, explosion and electrolyte outflow on the external environment when the cutting member 11 cuts the battery, and can reduce environmental pollution and improve the safety of the battery cutting test. The third protective wall 33 can also be connected to the side of the first protective wall 31 away from the cutting member 11 (i.e. the side of the first protective wall 31 facing the first driving member 12), so that the first protective wall 31, the third protective wall 33 and the mounting member 61 cooperatively define a mounting area of the first driving member 12. In this way, the protective effect on the first driving member 12 can be improved, and damage to the first driving member 12 can be reduced. The third protective wall 33 can be, but is not limited to, a plate, such as a flat plate or an arc-shaped plate. The third protective wall 33 can be, but is not limited to, made of an explosion-proof steel plate.

[0079] The first protective member 3 can also comprise a fourth protective wall 34. In this case, the first protective wall 31, the fourth protective wall 34 and the mounting member 61 cooperatively define a mounting area of the cutting member 11. In this way, the fourth protective wall 34 can shield the cutting member 11 in a direction away from the first protective wall 31, i.e. the first protective wall 31 and the fourth protective wall 34 shield opposite sides of the cutting member 11, which can reduce the influence of the battery fire, explosion and electrolyte outflow on the external environment when the cutting member 11 cuts the battery, and can reduce environmental pollution and improve the safety of the battery cutting test. The fourth protective wall 34 can be, but is not limited to, a plate, such as a flat plate or an arc-shaped plate. The fourth protective wall 34 can be, but is not limited to, made of an explosion-proof steel plate.

[0080] The first shielding piece 3 can simultaneously include the first shielding wall 31, the second shielding wall 32, and the third shielding wall 33, and the first shielding wall 31, the second shielding wall 32, the third shielding wall 33, and the mounting piece 61 can cooperatively enclose the mounting area of the cutting piece 11. The first shielding piece 3 can simultaneously include the first shielding wall 31, the second shielding wall 32, and the fourth shielding wall 34, and the first shielding wall 31, the second shielding wall 32, the fourth shielding wall 34, and the mounting piece 61 can cooperatively enclose the mounting area of the cutting piece 11. The first shielding piece 3 can simultaneously include the first shielding wall 31, the third shielding wall 33, and the fourth shielding wall 34, and the first shielding wall 31, the third shielding wall 33, the fourth shielding wall 34, and the mounting piece 61 can cooperatively enclose the mounting area of the cutting piece 11. In this way, the cutting piece 11 can be shielded in at least four directions, further reducing environmental pollution and improving the safety of the battery cutting test.

[0081] The first shielding piece 3 can simultaneously include the first shielding wall 31, the second shielding wall 32, the third shielding wall 33, and the fourth shielding wall 34, and the first shielding wall 31, the second shielding wall 32, the third shielding wall 33, the fourth shielding wall 34, and the mounting piece 61 can cooperatively enclose the mounting area of the cutting piece 11. In this way, the cutting piece 11 can be shielded in at least five directions, further reducing environmental pollution and improving the safety of the battery cutting test.

[0082] In this way, the first shielding piece 3 can improve the shielding effect on the cutting piece 11 and the protection effect on the first driving piece 12, can reduce the influence of the battery fire and explosion and the electrolyte flowing out of the battery when the cutting piece 11 cuts the battery on the external environment, can reduce environmental pollution, and can improve the safety of the battery cutting test. Moreover, the first shielding piece 3 can be flexibly provided with a safety protection structure as needed, has a simple structure, and can reduce costs.

[0083] In some embodiments, with reference to Figure 1 , Figure 2 , Figures 4 to 6 The mounting mechanism 6 further includes a bracket 62 connected to the second side 612 of the mounting piece 61. The mounting piece 61 is provided with a through hole 613 penetrating the first side 611 and the second side 612, the through hole 613 extends along the first direction, and the cutting piece 11 is arranged in the through hole 613. The first shielding wall 31 is connected to the second shielding wall 32 on the side facing the cutting piece 11, and the projection of the second shielding wall 32 on the mounting piece 61 along the support direction of the bracket 62 covers the projection of the through hole 613 and the cutting piece 11 on the mounting piece 61 along the support direction of the bracket 62.

[0084] The bracket 62 is used to support the mounting member 61. In some embodiments, the second direction may be parallel to the support direction of the bracket 62. When the battery cutting device 100 is in use, the bracket 62 can be supported on a horizontal surface, such as the ground or a platform, in which case the support direction of the bracket 62 is parallel to the direction of gravity. The first side 611 is the upper side of the mounting member 61, and the second side 612 is the lower side of the mounting member 61. Since the second protective wall 32 is connected to the side of the first protective wall 31 facing the cutting member 11, the second protective wall 32 is located below the cutting member 11. Since the projection of the second protective wall 32 along the support direction of the bracket 62 onto the mounting member 61 covers the projection of the through hole 613 and the cutting member 11 onto the mounting member 61, the orthogonal projections of the cutting member 11 and the through hole 613 on a plane perpendicular to the direction of gravity are located within the coverage area of ​​the orthogonal projection of the second protective wall 32 on a plane perpendicular to the direction of gravity.

[0085] Thus, when the cutting element 11 cuts the battery on the first side 611 of the mounting member 61, the outflowing electrolyte can flow through the through hole 613 to the second side 612 of the mounting member 61 and then fall onto the second protective wall 32. The second protective wall 32 can then receive the electrolyte flowing out when the battery is cut, facilitating its collection and centralized treatment, reducing damage to the battery cutting device 100 and environmental pollution caused by the electrolyte. Furthermore, the second protective wall 32 can fulfill the function of the receiving element 51 in the liquid collection mechanism 5, eliminating the need for a separate receiving element 51, simplifying the structure, and reducing costs.

[0086] In some embodiments, refer to Figure 5 The second protective wall 32 is inclined relative to the support direction of the bracket 62, and the second protective wall 32 has a lower end 321 away from the mounting member 61 along the support direction of the bracket 62. The battery cutting device 100 also includes a collection container 52, which is located on the side of the lower end 321 of the second protective wall 32 away from the mounting member 61.

[0087] The lower end 321 of the second protective wall 32 refers to the end away from the mounting member 61 along the support direction of the bracket 62. When the battery cutting device 100 is in use, the bracket 62 can be supported on a horizontal surface, and the support direction of the bracket 62 is parallel to the direction of gravity. At this time, the second protective wall 32 is an inclined surface set relative to the horizontal surface, and the lower end 321 of the second protective wall 32 is lower in the direction of gravity. The lower end 321 of the second protective wall 32 can realize the function of the confluence outlet 511 of the receiving member 51. The collection container 52 is located below the lower end 321 of the second protective wall 32.

[0088] In some embodiments, such as Figure 4 and Figure 5As shown in the figures, the second protective wall 32 can include a first wall segment 322 and a second wall segment 323, the first wall segment 322 is connected to the first protective wall 31, the second wall segment 323 is connected to the first wall segment 322 away from the first protective wall 31, and the low end 321 is located at one end of the second wall segment 323 away from the first wall segment 322. Among them, the inclination angle of the first wall segment 322 relative to the horizontal plane is greater than the inclination angle of the second wall segment 323 relative to the horizontal plane.

[0089] In this way, the electrolyte falling on the second protective wall 32 can converge at the low end 321 and flow out to the collection container 52 from the low end 321, which can improve the collection efficiency, facilitate the collection and centralized processing of the electrolyte flowing out of the cutting battery, and reduce the pollution to the environment.

[0090] In some embodiments, the first protective wall 31, the second protective wall 32, the third protective wall 33, the fourth protective wall 34, and the mounting 61 cooperatively surround the cutting member 11, which can reduce the splashing of the flowing electrolyte to the external environment and reduce the pollution to the environment. The fourth protective wall 34 can be arranged close to the low end 321 of the second protective wall 32, and the end of the fourth protective wall 34 away from the mounting 61 is arranged at a distance from the low end 321 of the second protective wall 32 to form a converging outlet 35. The collection container 52 is mounted at the converging outlet 35.

[0091] In some embodiments, the collection container 52 can be detachably mounted on the bracket 62. In this way, it is convenient to process the electrolyte collected in the collection container 52 and facilitate the cleaning and maintenance of the collection container 52.

[0092] In some embodiments, referring to Figures 1 to 6 , the second driving member 22 is arranged on the first side 611 of the mounting 61. The second protective member 4 includes a protective shell 41 connected to the first side 611 of the mounting 61, and the second driving member 22 is located in the protective shell 41.

[0093] The protective shell 41 can have an opening, and the open end of the protective shell 41 is connected to the first side 611 of the mounting 61 to form a protective space between the protective shell 41 and the first side 611 of the mounting 61, and the second driving member 22 is installed in the protective space, so as to isolate the second driving member 22 from the cutting member 11 and the clamping assembly 21. The protective shell 41 can also have other structures. The protective shell 41 can be made of, but not limited to, an explosion-proof steel plate. In some embodiments, the protective shell 41 is provided with an opening 411 on the side away from the clamping assembly 21 and the cutting member 11, and the opening 411 can be used for heat dissipation of the second driving member 22.

[0094] Thus, the second driving member 22 and the clamping assembly 21 are located on the same side of the mounting member 61, facilitating the second driving member 22 to drive the clamping assembly 21 to move; the protective shell 41 cooperates with the mounting member 61, so that the second driving member 22 is separated from the cutting member 11 and the clamping assembly 21, achieving protection of the second driving member 22, reducing damage of the second driving member 22 caused by battery fire explosion and electrolyte outflow when the cutting member 11 cuts the battery, and improving the safety of the battery cutting test.

[0095] In some embodiments, referring to Figures 1 to 3 , Figure 6 and Figure 7 , Figure 7 FIG. 6 shows an exploded view of the feeding mechanism 2, the second protective member 4 and the mounting member 61 in some embodiments of the present application. The feeding mechanism 2 further comprises a guide member 23, which is arranged on the first side 611 of the mounting member 61 and extends in the first direction. The clamping assembly 21 is slidably connected to the guide member 23.

The number of the guide member 23 can be one or two. Two guide members 23 can be arranged in the third direction, which is perpendicular to the first direction. The clamping assembly 21 is slidably supported on the two guide members 23, which can improve the stability of the sliding of the clamping assembly 21. In some embodiments, the feeding mechanism 2 further comprises a sliding block 24. The clamping assembly 21 is slidably connected to the guide member 23 through the sliding block 24.

[0097] The guide member 23 can slidably arrange the clamping assembly 21 on the first side 611 of the mounting member 61 and guide the sliding of the clamping assembly 21, so that the clamping assembly 21 is not easy to deviate from the movement direction, which can improve the cutting precision of the cutting member 11 on the battery and is conducive to improving the test effect of the battery cutting test.

[0098] In some embodiments, referring to Figure 6 and Figure 7 , the feeding mechanism 2 further comprises a transmission screw 25 and a transmission connecting member 26. One end of the transmission screw 25 is connected to the output end of the second driving member 22, and the other end is located outside the protective shell 41. The transmission screw 25 extends in the first direction. The transmission connecting member 26 is connected to the transmission screw 25. The clamping assembly 21 is connected to the transmission connecting member 26. The second driving member 22 drives the transmission screw 25 to rotate. The transmission screw 25 drives the transmission connecting member 26 to move along the transmission screw 25. The transmission connecting member 26 drives the clamping assembly 21 to move along the extension direction of the transmission screw 25.

[0099] In some embodiments, referring to Figures 3 to 7The clamping assembly 21 comprises a support 211, and a pressing member 212, a stop member 213 and a positioning member 214 arranged on the support 211. The pressing member 212 is configured to press the battery against the support 211 along a second direction. The stop member 213 is configured to resist the battery along a first direction. The positioning member 214 is arranged on the side of the stop member 213 close to the cutting member 11 along the first direction, and is configured to abut against the battery along a third direction. The third direction, the second direction and the first direction are perpendicular to each other. The positioning member 214 can be adjusted along the third direction.

[0100] The support 211 is configured to support the battery. The support 211 can be, but is not limited to, a plate, for example, a rectangular plate. The pressing member 212 cooperates with the support 211 to clamp the opposite sides of the battery along the second direction, thereby achieving the positioning of the battery along the second direction. The pressing member 212 can be a plate, for example, a rectangular plate. The pressing member 212 can also have other structures, such as a block or a strip. The number of the pressing member 212 can be at least two, and the at least two pressing members 212 are configured to press the opposite sides of the battery along the third direction, thereby improving the positioning of the battery along the third direction. The stop member 213 is configured to resist the side of the battery away from the cutting member 11 along the first direction, thereby achieving the positioning of the battery along the first direction. The stop member 213 can be a block, for example, a rectangular block. The stop member 213 can also have other shapes, such as a column. The positioning member 214 is configured to abut against at least one side of the battery along the third direction, thereby achieving the positioning of the battery along the third direction. The positioning member 214 can be a block, for example, a rectangular block. The positioning member 214 can also have other shapes, such as a column. The number of the positioning member 214 can be at least two, and the at least two positioning members 214 are configured to clamp the opposite sides of the battery along the third direction, thereby improving the positioning of the battery along the third direction.

[0101] By adjusting the arrangement position of the positioning member 214 on the support 211 along the third direction, the positioning position of the battery along the third direction can be adjusted. In this way, the cutting member 11 can cut different positions of the same battery along the third direction, or cut the same position of different batteries.

[0102] In some embodiments, the support 211 can be provided with a plurality of adjustment holes 2111 arranged along the third direction. The positioning member 214 is connected to different adjustment holes 2111, thereby fixing the positioning member 214 at different positions along the third direction on the support 211. Alternatively, the support 211 can be provided with a strip-shaped hole extending along the third direction. The positioning member 214 is connected to the support 211 through the strip-shaped hole, and the positioning member 214 can move along the strip-shaped hole, thereby adjusting the position of the positioning member 214 along the third direction.

[0103] In some embodiments, the plurality of adjustment holes 2111 are arranged in the first direction at intervals; the positioning member 214 is connected with the adjustment holes 2111 at different positions in the first direction, so as to fix the positioning member 214 at different positions in the first direction of the support member 211. In this way, the position of the positioning member 214 on the support member 211 can be adjusted in the first direction, and the positioning member 214 can abut against different positions of the battery in the first direction, so as to achieve the constraint and positioning of the battery with different first direction sizes.

The stop member 213 is located at one end of the gap 215 away from the entrance 216; the two positioning members 214 are located on the opposite sides of the gap 215 in the third direction and between the stop member 213 and the entrance 216. By arranging the gap 215, the support member 211 can avoid the cutting member 11, facilitate the cutting member 11 to cut off the battery in the second direction, and improve the cutting effect on the battery.

[0106] In some embodiments, the clamping assembly 21 can include a connecting rod and a locking knob, the connecting rod is connected to the support member 211 and is arranged parallel to the second direction, the pressing member 212 is movably connected to the connecting rod, and the pressing member 212 can adjust the distance from the support member 211 along the connecting rod; the locking knob is connected to the connecting rod and located on the side of the pressing member 212 away from the support member 211, and the locking knob is used to lock the pressing member 212.

[0107] In some embodiments, the battery cutting device 100 further includes a control module (not shown). The control module is configured to control the running speed of the first driving member 12 to control the cutting speed of the cutting member 11.

The first driving member 12 can drive the cutting member 11 to cut at a certain cutting speed. When the cutting member 11 rotates to cut, the cutting speed of the cutting member 11 refers to the rotating speed of the cutting member 11. When the cutting member 11 linearly moves to cut, the cutting speed of the cutting member 11 refers to the linear motion speed of the cutting member 11. The control module is electrically or signal connected with the first driving member 12, and the control module can control the first driving member 12 to drive the cutting member 11 to cut at different cutting speeds, i.e., the cutting speed of the cutting member 11 can be adjusted.

The second driving member 22 can also be a linear driving member, such as a linear motor, a hydraulic driving member, or a pneumatic driving member, etc., in which case the operating speed of the second driving member 22 refers to the linear motion speed of the second driving member 22. The second driving member 22 can drive the clamping assembly 21 to move along the first direction at a certain moving speed, and the clamping assembly 21 drives the battery to move towards the cutting member 11 to cut, so as to realize cutting of the battery at a certain feeding speed.
