[0036] In the laser cutting process of lithium-ion battery electrodes, strict requirements are placed on the cutting width and the positioning accuracy of the electrodes during transportation.

[0037] Currently, efficient electrode conveyance is typically achieved through the coordinated operation of pressure rollers and conveyor rollers. However, in the event of equipment downtime or other abnormalities, this operation can easily cause material shifting, affecting its accurate positioning. While vision positioning technology can be integrated to compensate for this deviation, the fluctuating pressure of the pressure rollers can also cause instability in the conveying process.

[0038] Based on the above problems, an embodiment of the present invention provides a pole piece cutting device, which is used in pole piece cutting and other processes. It has a simple structure, a stable and reliable transmission system, and good dust removal function compatibility.

[0039] See also Figure 1The electrode cutting device 10 includes an electrode conveying device 100.

[0040] In this embodiment, the electrode 20 cutting device further includes a laser cutter 200 . There are multiple electrode conveying devices 100 , which are arranged in sequence. The laser cutter 200 is arranged between two adjacent electrode conveying devices 100 .

[0042] Further, see Figure 2 The electrode conveying device 100 includes a driving component 110 , a conveying belt 120 and an adsorption component 130 .

[0044] In this embodiment, multiple conveyor belts 120 are provided to ensure that there is sufficient contact area between the conveyor belts 120 and the electrode 20, thereby achieving stable conveyance of the electrode 20. At the same time, the multiple conveyor belts 120 are arranged at intervals, and an adsorption member 130 is provided on the side of the conveyor belt 120 away from the electrode 20, so that the electrode 20 is adsorbed through the gap between the multiple conveyor belts 120 through the adsorption member 130, so that the electrode 20 is stably conveyed, thereby improving the conveying accuracy of the electrode 20, and further improving the cutting accuracy of the electrode 20.

[0045] Optionally, the adsorbent 130 may be a negative pressure adsorption device. Specifically, the adsorbent 130 may provide negative pressure below the conveyor belt 120, thereby stably positioning the electrode sheet 20 on the conveyor belt 120 and achieving precise positioning of the electrode sheet 20 to avoid problems such as offset. Furthermore, the adsorbent 130 may also adsorb dust and debris. Of course, the adsorbent 130 may also be other devices, which are not specifically limited herein.

By arranging multiple long conveyor belts 120 at intervals on the driving member 110, the driving member 110 can simultaneously drive the multiple long conveyor belts 120 to move, and the multiple long conveyor belts 120 can drive the electrode 20 to move; therefore, the multiple long conveyor belts 120 can stably convey the electrode 20, and the adsorption member 130 can provide sufficient adsorption force between the multiple conveyor belts 120, ensuring that the electrode 20 is stably adsorbed on the conveyor belt 120, thereby improving the conveying accuracy of the electrode 20.

[0049] In this embodiment, in order to further improve the adsorption efficiency, a plurality of adsorption holes 131 are provided on the adsorption member 130, and the adsorption holes 131 are located between two adjacent conveyor belts 120, thereby ensuring that the negative pressure adsorption force provided by the adsorption member 130 can fully act on the electrode 20, so that the electrode 20 is stably adsorbed on the conveyor belt 120, thereby improving the conveying accuracy of the electrode 20.

[0050] Furthermore, there are two driving members 110 , which are spaced apart from each other, and the conveying belt 120 is wound around the two driving members 110 .

[0051] In this embodiment, two driving members 110 are provided, and the conveying belt 120 is wound around the two driving members 110 , so that the conveying belt 120 is driven by the driving members 110 to move, thereby conveying the electrode 20 .

[0052] Furthermore, the driving member 110 includes a synchronous wheel 111 and a driving roller 112 . The synchronous wheel 111 is disposed at the end of the driving roller 112 for driving the driving roller 112 to rotate. The conveying belt 120 is wound around the driving roller 112 .

[0053] In this embodiment, the driving member 110 is composed of a synchronous wheel 111 and a driving roller 112, wherein the synchronous wheel 111 is located at one end of the driving roller 112, and is intended to promote the rotation of the driving roller 112, thereby driving the conveying belt 120 wound around the driving roller 112 to move, thereby realizing the conveying of the pole piece 20.

[0054] Furthermore, the driving rollers 112 of the two driving members 110 are arranged in parallel, and the plurality of belts are arranged at equal intervals along the length direction of the driving rollers 112 .

[0055] In this embodiment, the conveyor belt 120 is laid around two driving rollers 112 . The two driving rollers 112 are arranged in parallel, and the plurality of conveyor belts are evenly spaced and extend along the axial direction of the driving rollers 112 .

[0056] Of course, in other embodiments of the present invention, please refer to Figures 5 to 7 The conveyor belt 120 can also be in a sheet shape. It can be understood that for the content not mentioned in this embodiment, reference can be made to the relevant content in the above embodiment.

[0057] In detail, the conveying belt 120 is provided with a through hole 121 , and the adsorption member 130 adsorbs the pole piece 20 through the through hole 121 .

[0058] In this embodiment, by setting the conveyor belt 120 as a sheet structure, it can be ensured that the conveyor belt 120 has sufficient contact area with the electrode 20, thereby driving the stable transportation of the electrode 20; and in order to improve the adsorption capacity of the adsorption component 130, a through hole 121 is opened on the conveyor belt 120 to ensure that the negative pressure adsorption force provided by the adsorption component 130 can adsorb the electrode 20 through the through hole 121.

[0059] Furthermore, there are multiple through holes 121 , and the adsorption member 130 is provided with multiple adsorption holes 131 . The multiple through holes 121 are provided in a one-to-one correspondence with the multiple adsorption holes 131 , and the multiple through holes 121 are distributed in an array.

[0060] In this embodiment, by arranging a plurality of through holes 121 and a plurality of adsorption holes 131 in a one-to-one correspondence, it is ensured that the negative pressure adsorption force provided by the adsorption member 130 fully acts on the electrode 20 through the adsorption holes 131 and the through holes 121, so that the electrode 20 is stably adsorbed on the conveying belt 120, thereby improving the conveying accuracy of the electrode 20.

[0061] In summary, the utility model provides a pole piece conveying device 100 and a pole piece cutting device 10, which ensures that the conveying belts 120 have sufficient contact area with the pole piece 20 by setting a plurality of conveying belts 120, thereby realizing stable conveying of the pole piece 20.
