[0043] The protective cover 4 can completely block the cutting part to prevent safety accidents during cutting.

[0044] The working principle is as follows:

[0045] 1. Battery positioning and adjustment

[0046] The battery to be cut 207 is manually placed on the battery support block 205 of the battery positioning table 2, and precise positioning is achieved through the end rest and the left and right positioning plates 206 that can be adjusted left and right, ensuring consistent placement each time. Then, the operator manually translates the overall position of the battery 207 in the X and Y directions by operating the cross-roller guide rail of the cross-roller guide manual displacement table 203, and adjusts the size of the tab to be cut using a micrometer to align the tab above the lower knife 309 of the cutting mechanism 3. The displacement table supports smooth movement with high precision, suitable for tab cutting needs of different models of batteries.

[0047] 2. Automatic cutting process of the cutting mechanism

[0048] When the battery 207 is positioned, the thin air cylinder 306 is started, driving the floating joint connecting plate 304 and the slide rail connecting plate 303 downward through the floating joint 305. The slide rail connecting plate 303 moves downward along the linear guide rail 301, simultaneously driving the upper knife seat 317, the pressure plate 316, and other components to move synchronously. During this process:

[0049] Pressure stage: The pressure plate 316 first contacts the tab through the guide column 313 and the linear bearing 311, the compression spring 315 is compressed to generate elastic force, tightly pressing the tab on the upper surface of the lower knife 309 to prevent deformation and displacement of the tab during cutting.

[0050] Cutting stage: the thin cylinder 306 continues to descend, and the upper knife 319 descends synchronously with the upper knife seat 317 to form a shearing action with the lower knife 309. Since the upper knife 319 has a bidirectional shear blade slope, the cutting load is reduced, and the cutting edge is smooth without burrs; at the same time, the guide strip on one side of the upper knife 319 tightly fits the lower knife 309 assembly to avoid the upper and lower knife edges from being damaged by knocking during debugging or cutting.

[0051] 3. Automatic waste recycling

[0052] The waste generated during the cutting process is blown by the positive pressure air path connected by the air pipe joint 318 through the blowing hole at the bottom of the upper knife seat 317, and is introduced into the waste recycling box 116 through the waste guide block 308. The waste recycling box 116 is fixed on the support bottom plate 103 by the baffle buckle 114 and the waste recycling box baffle 115. When it is necessary to clean the waste, the waste recycling box baffle 115 is manually rotated by 90° to be unlocked, and the waste box can be pulled out and poured.

[0053] 4. Mechanism assembly and safety protection

[0054] Assembly assistance: the linear guide rail 301 is accurately positioned on the vertical plate 108 through the guide rail positioning pin 113 to ensure assembly accuracy; the slide rail block 302 prevents the slider of the linear guide rail 301 from falling during assembly, simplifying the installation process.

[0055] Safety protection: the protective cover 4 completely shields the cutting area to avoid the operator from contacting the moving blade and prevent safety accidents such as scratches during cutting.

[0056] The present patent realizes the full-process automation from battery positioning, automatic cutting to waste recycling through the coordinated action of various components, significantly improves the production efficiency and safety, and ensures the high precision and consistency of the tab cutting.

[0057] For ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles of the present utility model, and these improvements and refinements should be considered as the protection scope of the present utility model.
