[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, 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.

[0030] In related technologies, with the upgrading of battery products, the spacing of the tabs varies for different types of batteries. However, the existing cutting mechanisms for battery tabs have relatively fixed cutting positions, which are difficult to adapt to the tab cutting needs of different types of batteries. Therefore, how to cut the tabs for different types of batteries is a technical problem that urgently needs to be solved.

[0031] To address the aforementioned technical problems, this utility model provides an electrode cutting device, which can be found in the following reference. Figures 1 to 8 As shown, the electrode cutting device includes a base 3, a first displacement module 1, and a second displacement module 2.

[0032] The first displacement module 1 is slidably connected to the base 3 along the first direction; the second displacement module 2 is slidably connected to the first displacement module 1 along the second direction; the second displacement module 2 is connected to the cutting mechanism 4; the cutting mechanism 4 is slidably connected to the second displacement module 2 along the second direction; and includes a cutting part 401 for cutting the tabs; the cutting part 401 includes an initial position and a cutting position.

[0033] In the first and second directions mentioned in the above embodiments, this utility model establishes an XY coordinate system for the electrode cutting device, referring to... Figures 1 to 8 As shown, the X arrow points in a first direction, the Y arrow points in a second direction, and the first direction is perpendicular to the second direction, and both are directed at the height of the base 3.

[0034] Through the above technical solution, namely the tab cutting device provided by this utility model, when cutting the tabs of different types of batteries, the first displacement module 1 can slide relative to the base 3 along the first direction to bring the first displacement module 1 and the second displacement module 2 closer to the tab portion of the battery. Then, according to the different tab positions of different types of batteries, the cutting mechanism 4 on the second displacement module 2 moves along the second direction, and the cutting part 401 for cutting the tab is moved to the position corresponding to the tab of the battery, so that the cutting part 401 switches from the initial position to the cutting position. The device can cut the battery tabs. After cutting, the cutting part 401 can switch back to the initial position from the cutting position. The first displacement module 1 drives the second displacement module 2 and the cutting mechanism 4 to move in the opposite direction along the first direction. After the cutting mechanism 4 moves away from the battery tabs, the battery with the tabs cut can be removed to complete the cutting step. Through the above steps, the tab cutting device can adaptively adjust the cutting position of the tabs according to the different positions of the tabs of different types of batteries, that is, adjust the position of the cutting part 401 so that it can cut different types of tabs.

[0035] As a further development of the above embodiments, the number of cutting mechanisms 4 can also be any suitable. For example, a minimum of one cutting mechanism 4 can be provided, and each cutting mechanism 4 can be provided with at least one cutting part 401, so that the cutting mechanism 4 can move relative to the second displacement module 2 along the second direction to cut multiple tabs on the battery respectively. Alternatively, in order to improve cutting efficiency, the cutting mechanism 4 can correspond one-to-one with the number of battery tabs, and each cutting mechanism 4 can also be provided with a single cutting part 401, so that the cutting part 401 can correspond one-to-one with the number of battery tabs, so that multiple tabs of the battery can be cut simultaneously. This utility model does not make specific limitations in this regard.

[0036] Furthermore, the initial position and cutting position mentioned in the above embodiments can also be simply understood as follows: the initial position can represent the position where the cutting part 401 cannot cut the tab, and the cutting position can represent the position where the cutting part 401 can cut the tab.

[0037] In the above embodiments, the number of second displacement modules 2 can be arbitrarily suitable, and the number of cutting mechanisms 4 provided on a single second displacement module 2 can also be arbitrarily suitable. In this embodiment, referring to... Figures 1 to 4 As shown, the number of second displacement modules 2 can be two. The first displacement module 1 includes a first guide rod 110 extending along the second direction, and the first guide rod 110 passes through two second displacement modules 2 along the second direction.

[0038] In the above manner, the first guide rod 110 can guide the movement of the two second displacement modules 2 in the second direction, which can be referred to as... Figure 3 As shown, when the two second displacement modules 2 move along the second direction, the limiting action of the first guide rod 110 allows the two second displacement modules 2 to move more stably along the second direction. Furthermore, when cutting the tabs of different types of batteries, since the positions of the tabs are different, the two second displacement modules 2 can move closer to each other or further away from each other along the extension direction of the first guide rod 110, or move in the same direction along the extension direction of the first guide rod 110, thereby enabling the cutting of tabs at different positions.

[0039] Further details can be found in the above embodiments, which can be found in the following references. Figure 1 , Figure 3 , Figure 5 and Figure 7 As shown, the first guide rod 110 may include a first threaded section and a second threaded section (not shown in the figure) with opposite directions of rotation. Two second displacement modules 2 are respectively threaded to the first threaded section and the second threaded section. The two second displacement modules 2 move closer to or further away from each other by rotating the first guide rod 110.

[0040] With the above scheme, one of the two second displacement modules 2 can be threaded to the first threaded section, and the other can be threaded to the second threaded section. In this way, when adjusting the relative position of the two second displacement modules 2, the two second displacement modules 2 can be moved closer to each other or further away from each other by rotating the first guide rod 110.

[0041] In some implementations, reference Figures 1 to 8 As shown, the number of cutting mechanisms 4 can be two, and the second displacement module 2 can include a second guide rod 210 extending along the second direction, through which the two cutting mechanisms 4 are inserted.

[0042] The above-described scheme, which involves setting two cutting mechanisms 4 within a single second displacement module 2, allows for the simultaneous cutting of both tabs of the battery. In related technologies, battery tabs typically include a positive tab and a negative tab. With two cutting mechanisms 4, both the positive and negative tabs of a single battery can be cut simultaneously, improving cutting efficiency. Furthermore, depending on the position of the tabs of different battery types, the two cutting mechanisms 4 of a single second displacement module 2 can move via the guide and limit of the second guide rod 210. For example, the two cutting mechanisms 4 can move closer to or further away from each other along the extension direction of the second guide rod 210, or they can move in the same direction.

[0043] Furthermore, in cases where there is a need for large-capacity batteries in tablets or laptops, and given that the number of second displacement modules 2 is already two as mentioned in the above embodiments, the number of cutting mechanisms 4 can be [number missing]. Figure 1 and Figure 3 The four shown represent the total number of cutting mechanisms 4. The four cutting sections 401 of the four cutting mechanisms 4 can simultaneously cut multiple tabs of a large battery, thereby improving the cutting efficiency of the battery tabs.

[0044] For further details on the above technical solutions, please refer to... Figures 1 to 8 As shown, the second guide rod 210 includes a third threaded section and a fourth threaded section (not shown in the figure) with opposite directions of rotation. The two cutting mechanisms 4 move closer to or further away from each other by rotating the second guide rod 210.

[0045] With the above scheme, one of the two cutting mechanisms 4 can be connected to the third threaded section of the second guide rod 210, and the other cutting mechanism 4 can be connected to the fourth threaded section of the second guide rod 210. In this way, when adjusting the relative position of the two cutting mechanisms 4, the two cutting mechanisms 4 can be moved closer or further apart by rotating the second guide rod 210, so as to cut the tabs of different battery types.

[0046] In some implementations, reference Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, the cutting mechanism 4 may include a mounting base 410, a cutting assembly 420, and a driving member 430. The mounting base 410 is connected to the second guide rod 210 and includes a slide rail 411. The cutting assembly 420 includes a first cutting member 421 and a second cutting member 422 arranged at intervals along the extension direction of the slide rail 411. The first cutting member 421 and the second cutting member 422 are movable relative to the slide rail 411 and are both provided with a cutting part 401. The driving member 430 is connected to the mounting base 410 and is used to drive the first cutting member 421 and the second cutting member 422 to move closer to or further away from each other.

[0047] With the above solution, when the battery tabs are cut by the cutting part 401, the first cutting part 421 and the second cutting part 422 can be moved along the extension direction of the slide rail 411 by the driving member 430. For example, after the mounting base 410 moves along the extension direction of the second guide rod 210 and the relative position with the battery tabs is adjusted, the first cutting part 421 and the second cutting part 422 can be driven to move closer to each other by the driving member 430. When the cutting part 401 on the first cutting part 421 and the cutting part 401 on the second cutting part 422 come into contact with each other, it means that the cutting part 401 has switched from the initial position to the cutting position. Under the pressure of the two cutting parts 401, the battery tabs can be cut by the pressure of the cutting parts 401.

[0048] Furthermore, the arrangement of the first cutting member 421 and the second cutting member 422 mentioned in the above embodiments can be any suitable arrangement; for example, it can be referred to... Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, the cutting portions 401 of the first cutting member 421 and the second cutting member 422 can be arranged facing each other along the extension direction of the slide rail 411. In this way, when the first cutting member 421 and the second cutting member 422 approach each other, the two cutting portions 401 can contact each other to better and more efficiently cut the battery tabs.

[0049] In other words, the two cutting parts 401 move along the same axis in the extension direction of the slide rail 411, which is perpendicular to the height of the base 3. When the two cutting parts 401 approach and fit together in the extension direction of the slide rail 411, they can fit together completely, thus completely cutting the battery tabs, achieving a one-cut effect. This reduces or avoids the need for repeated cutting steps due to incomplete cutting of the tabs in a single cut, improving the cutting efficiency of the battery tabs.

[0050] In some implementations, reference Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, the cutting assembly 420 also includes an elastic buffer 423 connected to the first cutting member 421 and slidably connected to the slide rail 411.

[0051] Through the above scheme, the elastic buffer 423 can provide elastic buffer for the first cutting piece 421. That is, when the first cutting piece 421 and the second cutting piece 422 approach each other, in order to reduce or avoid the impact caused by the direct contact between the cutting part 401 of the first cutting piece 421 and the cutting part 401 of the second cutting piece 422, the elastic buffer 423 can provide a certain amount of elastic buffer for the first cutting piece 421. This can reduce the collision phenomenon caused by the two cutting parts 401 making hard contact with each other, and further improve the service life of the two cutting parts 401 on the first cutting piece 421 and the second cutting piece 422. In addition, the elastic buffer provided by the elastic buffer 423 can also reduce the hard contact between the cutting part 401 and the electrode tab, thereby reducing the occurrence of debris splashing during the cutting of the electrode tab.

[0052] As a further development of the above embodiments, the driving component 430 may also include any component with driving function, such as a driving cylinder, a motor or other structure.

[0053] In the embodiments of this utility model, reference is made to... Figures 1 to 6 As shown, the driving component 430 may include a first driving cylinder 431 and a second driving cylinder 432. The first driving cylinder 431 is connected to the elastic buffer 423, and the second driving cylinder 432 is connected to the second cutting component 422.

[0054] Through the above scheme, the elastic buffer 423 and the second cutting component 422 can be controlled separately by the first driving cylinder 431 and the second driving cylinder 432. Depending on the different heights of the tabs of different types of batteries in the vertical direction, the first driving cylinder 431 or the second driving cylinder 432 can be controlled separately, or the first driving cylinder 431 and the second driving cylinder 432 can be moved by different strokes, so that the tabs of different heights can be cut in the height direction.

[0055] Furthermore, the first drive cylinder 431 and / or the second drive cylinder 432 mentioned in the above embodiments can be any cylinder structure such as an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder. As long as it can stably drive the elastic buffer 423 and the second cutting member 422 to move stably, this utility model does not specifically limit the above specific implementation type.

[0056] As a further development of the above embodiments, the elastic buffer 423 can be any component with elastic buffering function, for example, refer to Figure 2 , Figure 4 and Figure 6As shown, the elastic buffer 423 may include a base 4231, a guide portion 4232, and an elastic portion 4233. The base 4231 is slidably connected to the slide rail 411, the guide portion 4232 is connected to the base 4231 and the first cutting member 421, and the guide portion 4232 is used to guide and limit the base 4231 when it moves relative to the first cutting member 421. The elastic portion 4233 is sleeved on the guide portion 4232, and the elastic portion 4233 is used to buffer the first cutting member 421 when the cutting part 401 is in the cutting position.

[0057] Through the above scheme, the first drive cylinder 431 can drive the base 4231 to move along the extension direction of the slide rail 411. Under the guidance and limitation of the guide part 4232, the elastic part 4233 can provide elastic buffering for the first cutting piece 421.

[0058] In other words, when the cutting portion 401 of the first cutting member 421 comes into contact with the cutting portion 401 of the second cutting member 422, under the elastic force of the elastic portion 4233, the elastic portion 4233 will be squeezed by the mutual approach of the base 4231 and the first cutting member 421, thereby providing elastic buffer for the first cutting member 421. Furthermore, under the limiting effect of the guide portion 4232, the elastic portion 4233 can also be prevented from deviating during the compression process, thereby stably providing elastic buffer for the first cutting member 421.

[0059] It should be noted that the elastic part 4233 mentioned in the above embodiments can be as follows: Figure 2 The guide portion 4232 of the spring shown can be as follows: Figure 2 The rod structure shown provides a stable limit for the spring when the spring is sleeved on the rod.

[0060] Furthermore, the number of springs and rods mentioned in the above embodiments can be multiple, and the number of each can correspond one-to-one. In this way, through the cooperation of multiple rods and springs, elastic buffering and stable limiting can be provided for the first cutting piece 421.

[0061] For example, in Figure 2 In the example shown, the number of springs in the rod can be two, and the two rods and two springs can correspond one-to-one.

[0062] This disclosure exemplarily describes the specific working process of the tab cutting device, which may include, for example, the following steps.

[0063] The first displacement module 1 moves relative to the base 3 along the first direction and stops moving after it reaches a position close to the battery tab.

[0064] The second displacement module 2 moves closer to or further away from each other via the first threaded section and the second threaded section of the first guide rod 110. After adjusting the two second displacement modules 2 to a position where the cutting mechanism 4 can approach the battery tab, the movement stops.

[0065] The cutting mechanism 4 moves closer to or further away from each other via the third and fourth threaded sections of the second guide rod 210 until all the multiple cutting parts 401 of the multiple cutting mechanisms 4 have moved to a position where the battery tabs can be completely cut, and then stops moving.

[0066] The first drive cylinder 431 and the second drive cylinder 432 control the elastic buffer 423 and the second cutting member 422 to move along the height direction respectively. After the two cutting parts 401 of the first cutting member 421 and the second cutting member 422 come into contact with the battery tabs, the battery tabs are cut.

[0067] After cutting, the first cutting piece 421 and the second cutting piece 422 will continue to move closer to each other under the driving action of the first driving cylinder 431 and the second driving cylinder 432 to ensure that the electrode tab is completely cut. After the cutting part 401 of the first cutting piece 421 and the cutting part 401 of the second cutting piece 422 come into contact with each other, the elastic buffer 423 will provide elastic buffer for the first cutting piece 421 to prevent the collision phenomenon of hard contact with the second cutting piece 422. The elastic part 4233 is compressed along the extension direction of the guide part 4232 to provide elastic buffer for the first cutting piece 421.

[0068] After the cutting is completed, the first drive cylinder 431 and the second drive cylinder 432 drive the elastic buffer 423 and the second cutting component 422 to move away from each other, and the first displacement module 1 moves in the opposite direction relative to the base 3 along the first direction, that is, the first displacement module 1 is retracted, thus completing the entire tab cutting process.

[0069] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope of protection claimed in this application.
