The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] Please refer to Figures 1 to 3The image shows a positioning fixture for lithium battery processing according to an embodiment of the present invention. It includes a main body plate 10, fixed limiting members 20 detachably disposed on one side and one end of the main body plate 10, and movable limiting members 30 disposed on the other side and another end of the main body plate 10. The top of the fixed limiting member 20 extends beyond the top surface of the main body plate 10, and the movable limiting member 30 is disposed on the top surface of the main body plate 10 via a motion component 40, so that the two fixed limiting members 20 and the two movable limiting members 30 are positioned... The top surface of the main body plate 10 forms a limiting space 50. The motion component 40 includes a lead screw 412 structure 41 disposed in the main body plate 10, a motion plate 42 connected to the lead screw 412 structure 41, a first mounting hole 43 arranged on the top of the motion plate 42, and a connecting rod 44 detachably mounted in the first mounting hole 43. The connecting rod 44 passes through the top of the main body plate 10 and is connected to the moving limiting member 30. One end of the lead screw 412 structure 41 is adapted to a driving member.

[0025] It is worth noting that by employing a lead screw 412 structure 41 with a detachable drive component at one end, the drive component can be easily disassembled after use, effectively reducing the overall size of the fixture body. Simultaneously, the motion component 40 is cleverly integrated within the main body plate 10, preventing it from extending outwards and further reducing the size of the main body plate 10. This design not only improves the compactness and neatness of the fixture body but also significantly enhances its portability and ease of use. More importantly, it helps improve accuracy and efficiency during the machining process.

[0026] In practice, firstly, the lithium battery cell is properly placed at the top center of the main body plate 10, ensuring that its adjacent sides are in close contact with the two fixed limiting members 20. Then, by driving the two lead screws 412 structure 41, the movable limiting member 30 is smoothly moved towards the battery cell until the battery cell is securely clamped within the limiting space 50 formed by the fixed limiting member 20, the movable limiting member 30, and the top of the main body plate 10. This process achieves precise clamping and positioning of the battery cell.

[0027] In this embodiment, both ends of the connecting rod 44 are threaded to facilitate a secure connection with the first mounting hole 43 on the main body plate 10 and the movable limiting member 30. By selecting different positions of the first mounting hole 43 to connect with the connecting rod 44, the maximum distance between the movable limiting member 30 and the fixed limiting member 20 can be flexibly adjusted. This design allows the size of the limiting space 50, which is formed by the fixed limiting member 20, the movable limiting member 30, and the top of the main body plate 10, to vary, thereby adapting to lithium battery cells of different sizes and greatly improving the versatility and adaptability of the fixture.

[0028] Furthermore, to flexibly adapt to lithium battery cells of different sizes, this design allows the two fixing limiting members 20 to be installed at different positions on the edge of the main body plate 10. Specifically, multiple orderly arranged second mounting holes 21 are carefully arranged on one side and one end of the main body plate 10. The fixing limiting member 20 consists of a limiting plate 22 and a mounting plate 23 extending from its bottom, with a third mounting hole 24 on the mounting plate 23. In actual installation, simply align the third mounting hole 24 precisely with the corresponding second mounting hole 21 on the main body plate 10, and then use fixing bolts to pass through these two mounting holes in sequence to securely install the fixing limiting member 20 in the predetermined position on the main body plate 10. This design ensures that the clamp can easily adapt to battery cells of various sizes, improving its versatility and practicality.

[0029] Specifically, the main body plate 10 has two accommodating cavities 11 inside, and the two accommodating cavities 11 are respectively used to install the lead screw 412 structure 41 corresponding to the two movable limiting members 30.

[0030] Please see Figure 4 Specifically, the lead screw 412 structure 41 includes two support blocks 411 spaced apart within the accommodating cavity 11, a lead screw 412 disposed between the two support blocks 411, and a movable block 413 disposed on the lead screw 412. One end of the lead screw 412 extends through the support block 411 and has a drive handle 414 extending therefrom. In this embodiment, the lead screw 412 structure 41 further includes a guide post disposed between the two support blocks 411, the guide post being used to guide the movable block 413.

[0031] Please see Figure 5 Furthermore, in order to prevent the drive handle 414 from extending beyond the edge of the main body plate 10, an inwardly recessed receiving groove 12 is provided on one side of the main body plate 10. The receiving groove 12 is configured to accommodate the drive handle 414 so that the drive handle 414 can be detachably connected to the drive component without protruding from the main body plate 10.

[0032] Furthermore, to simplify the assembly and disassembly process of the driving component and the limiting component, a driving groove 415 is provided at the end of the driving handle 414 away from the lead screw 412. The cross-section of the driving groove 415 is rectangular. This design allows the driving block (not shown) at the working end of any driving component (not shown), whether it is a small motor or a manually turned handle, to perfectly fit with the driving groove 415. When the lead screw 412 structure 41 needs to be driven, simply insert the driving block into the driving groove 415, and then the driving component will drive the driving handle 414 to rotate. After use, the driving block can be easily removed, quickly completing the disassembly of the driving component and greatly improving the flexibility and ease of use of the clamp.

[0033] Furthermore, in order to reduce the weight of the movable limiting member 30, the cross-section of the movable limiting member 30 is trapezoidal.

[0034] Specifically, the top of the main body plate 10 is provided with a movable groove 13. The size and shape of the movable groove 13 are designed to be adapted to the connecting rod 44 so as to guide the connecting rod 44 to drive the movable limiting member 30 to move on a predetermined path.

[0035] In summary, the positioning fixture for lithium battery processing in the above embodiments of this utility model has the following beneficial effects:

[0036] By employing a lead screw 412 structure 41 with a detachable drive component at one end, the drive component can be easily disassembled after use, effectively reducing the overall size of the fixture body. Simultaneously, the motion component 40 is cleverly integrated within the main body plate 10, preventing it from extending outwards and further reducing the size of the main body plate 10. This design not only improves the compactness and neatness of the fixture body but also significantly enhances its portability and ease of use. More importantly, it helps improve accuracy and efficiency during the machining process.
