Description

Technical Field

[0001] This utility model belongs to the field of battery manufacturing equipment technology, and in particular relates to a device for attaching electrode tabs. Background Technology

[0002] In automated lithium battery production lines, battery tab attaching equipment plays a crucial role in precisely attaching and welding (e.g., ultrasonic welding, laser welding) the cut tabs (key current-conducting components connecting the internal battery cells to the external circuitry) to designated positions on the battery current collector. The welding quality directly impacts the battery's internal resistance, connection reliability, and safety. Existing battery tab attaching equipment typically includes automated steps such as tab feeding, cutting, handling and positioning, attaching, and welding. However, during high-speed operation, a significant problem exists: dust easily accumulates on the tab surface before attachment and welding. These dust particles mainly originate from metal shavings generated during the upstream cutting process, frictional particles from moving parts inside the equipment, environmental dust, and electrostatic adsorption. Dust accumulation on the electrode surface severely hinders the effective metallurgical bonding of the welding interface, leading to incomplete / false welding, insufficient weld strength, increased internal resistance, and heat generation. This not only significantly reduces welding yield and battery performance consistency but also poses a safety hazard of localized overheating or even thermal runaway. Existing equipment's simple blowing and suction cleaning measures have limited effectiveness and pose a risk of secondary pollution. Environmental upgrades are costly. Therefore, the problem of dust contamination on the electrode surface has become a prominent bottleneck restricting the quality and safety reliability of lithium battery manufacturing and urgently needs to be solved.

The support ends of the two devices are respectively aligned with the output ends of the first tab conveying device 40 and the second tab conveying device 50. After the two mobile carriers 23 move to the positions of the two support devices 24, the support ends of the two support devices 24 move upward to correspond with the output ends of the first tab conveying device 40 and the second tab conveying device 20, so that the batteries to be processed are located between the two support devices 24 and the first tab conveying device 40 and the second tab conveying device 50. With the support of the support ends of the support devices 24, the first tab conveying device 40 and the second tab conveying device 50 complete the assembly of the tabs.

One end of each of the two moving mechanisms 43 extends above the two support devices 24, respectively, to process the electrodes on the batteries on the two moving carriers 23. The first plasma device 60 and the second plasma device 70 are respectively mounted on the two pressure roller mechanisms 42, and the first plasma device 60 and the second plasma device 70 are respectively positioned facing the conveying path of the feeding mechanism 41 to remove static electricity from the conveying belt passing through this area. The output end of the feeding mechanism 41 is located below one end of the moving mechanism 43. Figures 2-4 and Figure 6 As shown, the pressure roller mechanism 42 includes a steering wheel 421 and a mounting assembly 422. The mounting assembly 422 is fixedly mounted on the side of the support frame 30. The first plasma device 60 and the second plasma device 70 are respectively mounted on the two mounting assemblies 422. The mounting assembly 422 changes its angle to adjust the orientation angle of the first plasma device 60 and the second plasma device 70. The steering wheel 421 is rotatably mounted on the mounting assembly 422 at the lower position, and the steering wheel 421 is adjacent to the winding end of the feeding mechanism 41. The material roll changes direction after passing through the steering wheel 421 and enters the winding end of the feeding mechanism 41.

The adjustment hole is elongated. The mounting bracket 4221 is mounted on the side of the support frame 30. One end of the rotating component 4222 is rotatably mounted on the mounting bracket 4221. Adjusting the angle of the rotating component 4222 changes the angle of the first plasma device 60 and the second plasma device 70. The steering wheel 421 is rotatably mounted below one end of the rotating component 4222.

[0029] like Figures 1-4As shown, the feeding mechanism 41 is assembled from a motor 411, an unwinding mechanism 412, a winding mechanism 413, an output mechanism 414, a power shaft 415, and several steering shafts 416.

The material roll is drawn out from the unwinding mechanism 412, passes around the steering shaft 416 and enters the output mechanism 414. It passes around the steering shaft 416, the power shaft 415 and the steering wheel 421 and enters the winding mechanism 413 to complete the winding. The power shaft 415 drives the winding mechanism 413 to rotate. While the power shaft 415 pulls the material roll to convey, the winding mechanism 413 pulls one end of the material roll to take it in.

[0030] like Figures 1-4 As shown, the moving mechanism 43 is composed of a mounting base 431, a rotary motor 432, a lifting assembly 433, and a negative pressure head 434.

The lifting assembly 433 is slidably installed on the mounting base 431 and can move back and forth between the output mechanism 414 and the conveying device 20. The rotary motor 432 is fixedly installed on one end of the mounting base 431, and the rotating end of the rotary motor 432 passes through the side of the mounting base 431 and is threadedly connected to the lifting assembly 433. The rotation of the rotary motor 432 drives the lifting assembly 433 to move back and forth on the mounting base 431. The negative pressure head 434 is fixedly installed on the lifting end of the lifting assembly 433 and moves with the lifting assembly 433 to adsorb the electrode.

The conveyor frame 21 is fixedly installed on the top of the base 10. The conveyor belt assembly 22 includes a conveyor belt, auxiliary shafts, and a power source. The conveyor belt assembly 22 is installed on the conveyor frame 21. The power source drives the conveyor belt to rotate around multiple auxiliary shafts. The mobile carriers 23 are fixedly installed on the transmission belt. The two mobile carriers 23 are moved by the conveyor belt. The support devices 24 are set on the side of the conveyor frame 21 to support the battery processing positions on the mobile carriers 23 after they have moved into place. They are aligned with the two negative pressure heads 434 respectively.

[0032] like Figure 1 and Figure 5 As shown, two limiting devices 211 are provided on the side of the conveyor frame 21, and the limiting ends of the two limiting devices 211 can extend toward the other side of the conveyor frame 21, respectively used to limit the positions of the two ends of the conveyor belt and prevent the two moving carriers 23 from moving beyond the range.
