Furthermore, the lack of flexibility in adjustment during the cutting process can lead to insufficient lead-cutting precision, affecting the subsequent assembly and performance of the lithium battery. Therefore, those skilled in the art provide a lithium battery lead-cutting device to solve the problems mentioned in the background art. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figures 1-4 As shown, this utility model provides a technical solution: a lithium battery cutting device, including a base plate 1 for supporting the upper part, a telescopic mechanism 2 for adjusting the axial cutting position is provided on one side of the top of the base plate 1, an angle adjustment mechanism 3 for adjusting the cutting angle is provided at one end of the telescopic mechanism 2, and a placement component 4 for placing the lithium battery is provided on one side of the top of the base plate 1.

[0024] By setting the base plate 1 as a basic support, a stable installation platform is provided for the entire device, ensuring structural stability during operation. The telescopic mechanism 2 can flexibly adjust the axial cutting position, allowing the device to adapt to the cutting requirements of lithium batteries with different axial dimensions, thus expanding its applicability. The angle adjustment mechanism 3 can precisely adjust the cutting angle to meet the processing requirements of different cutting angles for lithium batteries, improving the flexibility and accuracy of cutting. The placement component 4 can reliably position and fix the lithium battery, preventing displacement during cutting, ensuring both cutting quality and operational safety. The cooperation of these mechanisms makes the entire device highly efficient, adaptable, and safe in lithium battery cutting operations, effectively solving the shortcomings of traditional cutting devices in terms of position and angle adjustment and workpiece fixation.

[0025] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, the telescopic mechanism 2 includes a first fixed column 21, which is fixedly connected to the top of the base plate 1 on one side. A first connecting column 22 is rotatably connected to the outer surface of the top of the first fixed column 21. A first connecting rod 23 is hinged to one end of the first connecting column 22, and a first hinge 24 is hinged to the end of the first connecting rod 23 away from the first fixed column 21.

[0026] Through the rotational connection between the first connecting column 22 and the first fixed column 21, the hinge between the first connecting column 22 and the first connecting rod 23, and the hinge between the first connecting rod 23 and the first hinge 24, the telescopic mechanism 2 can achieve multi-angle rotation and preliminary length adjustment in the horizontal direction, laying the foundation for subsequent precise adjustment of the cutting position and improving the flexibility of the device in the horizontal direction.

[0027] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the first hinge 24 is hinged to a second connecting post 25 at the end away from the first connecting rod 23. The inner cavity of the second connecting post 25 is slidably connected to a spindle 26. The outer surface of the spindle 26 is slidably connected to a return spring 27, which is fixedly connected to one end of the second connecting post 25.

[0028] The hinge between the first hinge 24 and the second connecting column 25 further increases the degree of freedom of movement of the telescopic mechanism 2. The sliding action of the pivot column 26 in the inner cavity of the second connecting column 25 with the return spring 27 enables the telescopic mechanism 2 to achieve axial telescopic movement. The return spring 27 can help the mechanism return to its original position after telescopic movement, ensuring the convenience and stability of telescopic adjustment and facilitating precise control of the axial position of the cut.

[0029] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the second connecting post 25 is hinged to a second hinge 28 at the end away from the first hinge 24, and the second hinge 28 is hinged to a third connecting post 29 at the end away from the second connecting post 25.

[0030] The hinged design of the second connecting post 25 and the second hinge 28, and the second hinge 28 and the third connecting post 29 further expands the range of motion of the telescopic mechanism 2, making the linkage of the entire telescopic mechanism 2 stronger and enabling it to move the angle adjustment mechanism 3 more flexibly, thereby adapting to the cutting needs of different positions.

[0031] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the angle adjustment mechanism 3 includes a second fixed column 31, which is fixedly connected to the end of the third connecting column 29 away from the second hinge 28. Adjustable handles 32 are fixedly connected to both ends of the outer surface of the second fixed column 31. A first motor 33 is fixedly connected to one end of the inner cavity of the second fixed column 31. A second motor 34 is rotatably connected to the end of the first motor 33 away from the second fixed column 31.

[0032] The second fixed column 31 serves as the basic component of the angle adjustment mechanism 3, and receives the power transmission of the telescopic mechanism 2 through a fixed connection with the third connecting column 29. The adjustable handle 32 facilitates manual adjustment of the position of the angle adjustment mechanism 3 by the operator. The rotatable connection between the first motor 33 and the second motor 34 allows the second motor 34 to rotate around the output shaft of the first motor 33, providing power and basic angle adjustment capability for the cutting angle adjustment.

[0033] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the end of the second motor 34 away from the first motor 33 is rotatably connected to a fourth connecting post 35. The end of the fourth connecting post 35 away from the second motor 34 is rotatably connected to a second connecting rod 36. One end of the second connecting rod 36 is fixedly connected to an adjusting post 37. The end of the adjusting post 37 away from the second connecting rod 36 is fixedly connected to a third connecting rod 38. A cutting blade 39 is rotatably connected to the outer surface of one end of the third connecting rod 38.

[0034] The second motor 34 drives the fourth connecting column 35 to rotate, which in turn drives the second connecting rod 36 to move through the hinge between the fourth connecting column 35 and the second connecting rod 36. The second connecting rod 36 then drives the adjusting column 37 and the third connecting rod 38 to move, ultimately changing the position and angle of the cutting blade 39. This multi-stage transmission structure makes the adjustment of the cutting blade 39 more precise, adapting to different cutting angles and improving the flexibility and accuracy of cutting.

[0035] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, a fifth connecting post 310 is fixedly connected to the outer surface of the second motor 34. A connecting outer ring 311 is rotatably connected to the end of the fifth connecting post 310 away from the second motor 34. A connecting shaft 312 is rotatably connected to the inner cavities on both sides of the connecting outer ring 311. The connecting outer ring 311 is rotatably connected to the adjusting post 37 through the connecting shaft 312.

[0036] The cooperation of the fifth connecting column 310, the connecting outer ring 311 and the connecting shaft 312 provides support and guidance for the movement of the adjusting column 37, ensuring the stability of the adjusting column 37 when it moves with the second connecting rod 36, avoiding the shaking of the adjusting column 37 from affecting the cutting accuracy, and making the operation of the angle adjusting mechanism 3 more stable and reliable.

[0037] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the placement component 4 includes a frame 41, which is fixedly connected to one side of the top of the base plate 1. The inner cavity of the frame 41 is fixedly connected with a number of symmetrically arranged positioning posts 42 for placing lithium batteries.

[0038] The frame 41 provides an installation base for the positioning stakes 42. The symmetrically arranged positioning stakes 42 can effectively position and fix the lithium battery, preventing it from moving during the cutting process and ensuring the accuracy and safety of the cutting. At the same time, the arrangement of several sets of positioning stakes 42 can adapt to the placement requirements of lithium batteries of different specifications.

[0039] Working principle: When the lithium battery cutting device is working, the lithium battery to be cut is first placed on the positioning stake 42 of the placement component 4. The lithium battery is fixed by the symmetrically arranged positioning stake 42. Then, according to the position requirements of the lithium battery cutting, the operator adjusts the handle 32 to act on the telescopic mechanism 2, thereby driving the angle adjustment mechanism 3 to adjust the axial position. During this process, the first connecting column 22 can rotate around the first fixed column 21, driving the first connecting rod 23, the first hinge 24 and other components to move. The hinge between the first hinge 24 and the second connecting column 25, and the hinge between the second connecting column 25 and the second hinge 28, and the hinge between the second hinge 28 and the third connecting column 29, enable the entire telescopic mechanism 2 to rotate flexibly. Simultaneously, the pivot column 26 slides within the inner cavity of the second connecting column 25, cooperating with the extension and retraction of the return spring 27 to achieve axial length adjustment of the telescopic mechanism 2. This, in turn, drives the angle adjustment mechanism 3 to move axially, initially adjusting the relative position of the cutting blade 39 and the lithium battery. Once the axial position is properly adjusted, the first motor 33 starts, driving the second motor 34 to rotate around its output shaft, achieving initial angle adjustment of the second motor 34. The second motor 34 starts, driving the fourth connecting column 35 to rotate. The fourth connecting column 35, through its hinge with the second connecting rod 36, drives the second connecting rod 36 to move, which in turn drives the adjusting column 37 to move. During this process, the fifth connecting column 310, the connecting outer ring 311, and the connecting shaft 312 provide support and guidance for the adjusting column 37, ensuring stable movement of the adjusting column 37. The adjusting column 37 drives the third connecting rod 38 to move, thereby enabling precise angle adjustment of the cutting blade 39 at one end of the third connecting rod 38. Once the position and angle of the cutting blade 39 are adjusted to the correct position, the cutting blade 39 begins to rotate, performing a cutting operation on the lithium battery placed on the positioning post 42. Throughout the process, the return spring 27 ensures that the telescopic mechanism 2 returns to its original position promptly after adjustment, ensuring the accuracy of the next operation. The hinged and rotating connections of each component guarantee the flexibility and stability of the entire device, thus efficiently and accurately completing the lithium battery cutting operation.

[0040] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
