[0051] The length measuring component 4 is set on the measuring workbench 12, and the length extension direction of the length measuring component 4 corresponds to the extension direction of the electrode tab of the battery cell on the measuring workbench 12.

[0052] In this embodiment, as Figure 1-2 As shown, upon first use, the battery cell is first unfolded and laid flat on the cutting worktable 11. Then, the tabs of the battery cell are adjusted to the tab cutting station of the cutting device 3. The lifting and translating transport mechanism 2 moves the adsorption assembly 27 to the cutting station and fixes the battery cell. The cutting device 3 then begins cutting the tabs of the battery cell. After cutting, the lifting and translating transport mechanism 2 moves the adsorption assembly 27 and the battery cell to the measuring worktable 12. Finally, the distance between the tabs after cutting is measured manually using the length measuring assembly 4, and then the battery cell is cut according to the measurement results.

[0053] Specifically, such as Figure 1 As shown, the length measuring component 4 is a film ruler.

[0054] In this embodiment, as Figure 1 As shown, the film ruler includes a ruler body and a scale on the ruler body. The ruler body is placed horizontally on the measuring worktable 12, and the direction of the scale on the ruler body is consistent with the extension direction of the battery cell tabs.

The spacing between the cutters is different. The lower platform 32 is provided with cutting grooves corresponding to the cutters, and the positions of the cutting grooves correspond to the electrode tab cutting positions.

[0062] During operation, the telescopic drive assembly 33 drives the cutter assembly 34 downwards, the cutter passes through the battery cell tab and enters the cutting groove, completing the cutting of the tab. During the cutting process, the lower platform 32 provides support for the tab, ensuring stability. The telescopic drive assembly 33 can be implemented using a cylinder, hydraulic cylinder, or electric push rod, etc. By controlling the telescopic stroke of the telescopic drive assembly 33, the descent depth of the cutter can be adjusted to ensure the cutting effect.

Two vertical slide rails 24 are provided on the mobile platform to guide the vertical movement of the lifting connecting plate. The lifting drive assembly 25 uses a cylinder, or it can be an electric push rod structure, adjusting the height of the lifting connecting plate by controlling the extension of its telescopic end.

[0076] The lifting connecting plate is equipped with a slider that matches the vertical slide rail 24. The slider slides in cooperation with the vertical slide rail 24 to ensure smooth vertical movement of the lifting connecting plate. The rotation drive component 271 of the adsorption assembly 27 is a servo motor, which can be combined with an encoder to control the rotation angle of the suction cup assembly 272. The suction cup assembly 272 includes a suction cup mounting plate and multiple suction cups, which are evenly distributed on the suction cup mounting plate.

[0077] During operation, the linear drive mechanism 22 controls the moving platform to move between the cutting station and the measuring station, the lifting drive assembly 25 controls the lifting connecting plate to move up and down to adjust the height of the adsorption assembly 27, and the rotation drive assembly 271 controls the rotation posture of the suction cup assembly 272 to adapt to the operational needs of different stations. Through the coordinated work of these mechanisms, the lifting and translational transport mechanism 2 can accurately grasp the battery cells and transfer them between various stations, realizing the transport operation.

[0086] Limiting block 532 is disposed on the upper surface of the battery cell positioning seat and is fixedly connected to connecting block 531.

[0087] In this embodiment, as Figure 4 As shown, the cell positioning base has a rectangular structure, with its upper surface serving as the cell placement surface for placing and fixing the cell. A fixing limit block 51 is fixedly installed on one side of the cell positioning base, serving as a fixed reference surface when placing the cell. A sliding groove 511 is provided along the length of the cell positioning base, penetrating both the upper and lower surfaces of the cell positioning base.

[0088] The telescopic drive assembly is an electric push rod, with its fixed end fixed to the lower surface of the cell positioning seat and its telescopic end connected to the connecting block 531. The telescopic drive assembly's telescopic direction is parallel to the extension direction of the slide groove 511. By controlling the telescopic drive assembly's telescopic amount, the position of the connecting block 531 within the slide groove 511 can be adjusted. The connecting block 531 has a T-shaped structure, with its horizontal portion located below the cell positioning seat and its vertical portion passing through the slide groove 511 and connecting to the limiting block 532. The limiting block 532 is located on the upper surface of the cell positioning seat, with its side facing the fixed limiting block 51 forming a limiting surface to restrict the position of the cell.

[0089] In use, the distance between the limiting block 532 and the fixed limiting block 51 is adjusted by controlling the extension and retraction of the telescopic drive assembly according to the size of the battery cell, so that it matches the size of the battery cell. After the battery cell is placed on the battery cell positioning seat, the fixed limiting block 51 and the limiting block 532 work together to fix the battery cell in the predetermined position, ensuring that the battery cell does not shift during the cutting process. When it is necessary to process battery cells of different specifications, it is only necessary to adjust the telescopic drive assembly and change the position of the limiting block 532 to adapt to the positioning requirements of battery cells of different sizes, without the need to replace other parts.
