[0032] In this embodiment, the diaphragm 200, the pole piece 100, the diaphragm 200 and the pole piece 100 are stacked and wound in sequence from top to bottom. In some feasible embodiments, refer to Figure 3 , and can also be stacked and wound in sequence from top to bottom according to the order of pole piece 100, diaphragm 200, pole piece 100 and diaphragm 200. Similarly, the pole piece 100 in the battery pole piece package can be separated and recovered through adaptation and adjustment, and the two pole pieces 100 in the disassembled battery pole piece package can be recycled and reused respectively.

[0033] Specifically, Figure 4-Figure 6 As shown, the battery electrode sheet collection and cutting device provided in this embodiment includes a frame, a collection mechanism and a cutting mechanism, and the collection mechanism and the cutting mechanism are both arranged on the frame, wherein the collection mechanism is used to divide the battery electrode sheet package into two groups and separately wind and collect one of the electrode sheets 100 (the electrode sheet 100 located in the outermost layer) to form an electrode sheet roll 300, specifically, one group is one of the electrode sheets 100, and the other group is a diaphragm 200, another electrode sheet 100 and another diaphragm 200, and the cutting mechanism is used to cut the electrode sheet roll 300 formed by winding. Further, the remaining diaphragm 200, another electrode sheet 100 and another diaphragm 200 are further grouped, and one of the diaphragms 200 is collected separately until the other electrode sheet 100 is in the outer layer, at this time, the collection and cutting steps of the electrode sheet 100 are repeated again, and the other electrode sheet 100 is separately wound, collected and cut, and the separate collection and cutting of the two electrode sheets 100 are completed.

[0034] Preferably, if Figure 4 As shown, the frame includes a support frame 11 and a workbench 12 , and the workbench 12 is arranged on the top of the support frame 11 .

[0036] Optionally, the collecting mechanism further includes a first fixed seat (not shown in the figure). Specifically, the first fixed seat is fixed on the workbench 12, and the first driving member 21 is installed on the first fixed seat.

[0037] Preferably, the reel 22 is divided into a connecting portion and a cutting portion along its axial direction, the connecting portion is close to the first driving member 21, and the pole piece reel 300 is fixed to the cutting portion. Figure 6 As shown, the cutting portion includes two supporting plates 221 arranged opposite to each other, and a cutting cavity is formed between the two supporting plates 221. Through the above arrangement, the cutting mechanism can be extended into the cutting cavity to ensure that each layer of the pole piece roll 300 can be cut.

[0038] Furthermore, in order to facilitate the collection of the cut electrode 100, the workbench 12 is provided with a collecting groove 121, and the projection of the reel 22 falls on the collecting groove 121. A barrel is also provided inside the support frame 11, and the electrode roll 300 is located directly above the barrel. After the cutting mechanism completes the cutting, the electrode roll 300 breaks and falls into the barrel. In this process, no operator assistance is required, which reduces the harm to the human body caused by harmful substances and improves the recycling efficiency.

[0039] To facilitate the collection of the pole piece 100, the collection mechanism also includes a separation component, specifically, the separation component includes a scraper (not shown in the figure), wherein the scraper is arranged on a frame, specifically, the scraper is arranged on a workbench 12, and the blade of the scraper abuts against the upper surface of the pole piece 100, that is, between the pole piece 100 and the diaphragm 200 closely attached thereto, so as to separate the pole piece 100 and the diaphragm 200 closely attached to the pole piece 100, thereby facilitating the winding of the pole piece 100 separately to form a pole piece roll 300.

[0040] Optionally, in other feasible embodiments, the scraper may be replaced by an air gun, and the air outlet of the air gun is aimed between the pole piece 100 and the diaphragm 200 closely attached thereto, which can also separate the pole piece 100 from the diaphragm 200 closely attached thereto.

[0041] Further, the collecting mechanism also includes a second fixed seat 10 fixed on the workbench 12, and the separation assembly also includes a positioning shaft 31, which is installed on the second fixed seat 10, the positioning shaft 31 is higher than the reel 22, and the positioning shaft 31 presses the pole piece 100 upward, thereby bending the pole pieces 100 located on both sides of the positioning shaft 31, and further, the blade of the scraper presses the contact between the pole piece 100 and the positioning shaft 31, so that the positioning shaft 31 can provide support for the blade in the process of separating the pole piece 100 from the diaphragm 200, which can ensure that the pole piece 100 is scraped off the diaphragm 200 smoothly on the one hand, and prevent the diaphragm 200 from being damaged on the other hand. Preferably, the axial direction of the positioning shaft 31 is parallel to the first direction to avoid affecting the winding of the pole piece 100 on the reel 22.

[0042] In this embodiment, the cutting mechanism includes a guide rail 41, a sliding member 42 and a cutting member 43, wherein the guide rail 41 is arranged along a first direction, and the guide rail 41 can be connected to a frame, specifically, connected to a workbench 12. Further, the sliding member 42 is slidably arranged on the guide rail 41 and can slide along the guide rail 41.

The cutting member 43 has a first position and a second position, and the cutting member 43 can slide along the guide rail 41 between the first position and the second position. In this process, the cutting member 43 can cut off each layer of the pole piece roll 300.

[0043] Furthermore, the cutting mechanism also includes a connecting plate 44 arranged along the first direction, and the connecting plate 44 is connected to the second fixed seat 10. Preferably, the connecting plate 44 is arranged below the positioning shaft 31 to prevent affecting the separation of the pole piece 100. The guide rail 41 is installed on the connecting plate 44. Further preferably, the guide rail 41 is located between the positioning shaft 31 and the reel 22 to ensure that the cutting of the pole piece reel 300 can be carried out smoothly, that is, the connecting plate 44 is closer to the reel 22 relative to the positioning shaft 31, and the guide rail 41 is connected to the side of the connecting plate 44 away from the positioning shaft 31.

[0044] Preferably, when the cutting member 43 slides from the first position to the second position along the guide rail 41, one side of the cutting member 43 can extend into the cutting cavity, and the opposite side of the cutting member 43 can cut off the outermost layer of the pole piece roll 300, thereby ensuring that the pole piece roll 300 is completely cut.

[0045] Furthermore, the cutting mechanism further comprises a sliding driving member, the output end of which is drivingly connected to the sliding member 42 , and the sliding driving member is configured to drive the sliding member 42 to slide along the guide rail 41 , thereby driving the cutting member 43 to slide along the guide rail 41 .

[0046] Optionally, the cutting piece 43 in this embodiment is a gear hob. Specifically, the gear hob includes a cutter shaft and a plurality of cutting teeth circumferentially connected to the cutter shaft. The gear hob rotates while sliding along the guide rail 41. Under the action of rotation, the cutting teeth apply force to the pole piece roll 300, thereby cutting the pole piece roll 300.

Preferably, the rotating shaft 45 is spaced from the reel 22 to avoid interference between the rotating shaft 45 and the reel 22, thereby affecting the cutting of the pole piece roll 300.

[0048] In other feasible embodiments, the cutting member 43 may be selected as a blade, and each layer of the pole piece roll 300 may also be cut.
