For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The slicing device 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0025] like Figure 1 As shown, the sheet separation device 1 according to the embodiment of the utility model includes a bracket, a sliding frame 10 , a sheet suction device 20 , a paper suction device 30 and a static electricity removal device 40 .

[0026] The sliding frame 10 is movably arranged on the bracket. The film suction device 20 is movably arranged on the sliding frame 10 and is suitable for sucking the battery film. The paper suction device 30 is movably arranged on the sliding frame 10 and is suitable for sucking the separator paper. The static electricity removal device 40 is suitable for removing static electricity from the battery film sucked by the film suction device 20.

[0027] Specifically, there is an overlapping area 2 underneath the slicing device 1, with a battery cell conveyor belt 5 and a paper stacking area 4 on either side of the overlapping area 2. Alternatingly stacked battery cells and separators are placed in the paper stacking area 4. The paper stacking area 4 is suitable for stacking separated separators. The separated battery cells 3 are placed on the battery cell conveyor belt 5 and transported to subsequent processes.

[0028] When separating the sheets, the sheet suction device 20 descends to absorb the cells in the overlapping area 2. The sliding frame 10 moves to move the cells 3 to the top of the cell conveyor belt 5. The sheet suction device 20 descends and releases the cells 3 to place the cells 3 on the cell conveyor belt 5. The paper suction device 30 descends and absorbs the separator paper in the overlapping area 2. Then the sliding frame 10 moves to move the paper suction device 30 and the separator paper to the top of the paper stacking area 4. The paper suction device 30 descends and releases the separator paper. This cycle separates the alternately stacked cells and separator paper.

[0029] During the process, the static electricity removal device 40 performs static electricity elimination on the battery cell adsorbed by the suction device 20 after the battery cell is adsorbed by the suction device 20, thereby eliminating the static electricity on the battery cell and causing the separator paper adsorbed on the battery cell by static electricity to separate from the battery cell, thereby preventing the battery cell from carrying the separator paper to the subsequent process.

[0030] According to the slicing equipment 1 of the embodiment of the utility model, by setting up the static electricity removal device 40, the static electricity removal device 40 can be used to eliminate the static electricity of the battery cells adsorbed by the suction device 20, thereby eliminating the static electricity on the battery cells. Compared with the slicing equipment in the related art, it can avoid the battery cells adsorbed by the suction device 20 from carrying static electricity, and avoid the battery cells adsorbed by the suction device 20 from adsorbing the separator paper through static electricity, so that the separator paper adsorbed on the battery cells can be separated from the battery cells, and the battery cells are prevented from carrying the separator paper to the subsequent process, and the abnormal situation of suction carrying the paper is avoided, thereby improving the reliability of slicing.

[0031] Therefore, the slicing device 1 according to the embodiment of the utility model has the advantages of high reliability and the like.

[0032] The slicing device 1 according to a specific embodiment of the utility model is described below with reference to the accompanying drawings.

[0033] In some specific embodiments of the present invention, Figure 1 As shown, the sheet separation device 1 according to the embodiment of the utility model includes a bracket, a sliding frame 10 , a sheet suction device 20 , a paper suction device 30 and a static electricity removal device 40 .

[0034] Specifically, the static electricity removal device 40 is a plasma air knife and is suitable for blowing static electricity removal plasma to the battery cell adsorbed by the film suction device 20. In this way, not only can the static electricity on the battery cell adsorbed by the film suction device 20 be eliminated by the static electricity removal ions, but also the battery cell and the separator paper can be further separated by blowing the battery cell, thereby further improving the reliability of the separation.

[0035] Specifically, the plasma air knife can be arranged around the overlapping area 2, and can not only blow the battery cell when sucking the battery cell, but also blow the separator paper when sucking the separator paper. This can not only facilitate the separation of the battery cell and the separator paper when sucking the cell with the paper, but also facilitate the separation of the separator paper and the battery cell when sucking the paper with the cell.

[0036] It is understandable to those skilled in the art that, since the separator paper has a certain air permeability, when the separator paper is adsorbed, the air pressure can easily pass through the separator paper and act on the battery cell below the separator paper, resulting in the situation where the paper is adsorbed with the cell.

[0037] After the paper suction device 30 absorbs the separator paper, if the paper suction device 30 absorbs the battery cells under the separator paper together, the plasma wind knife blows to cause the battery cells to separate from the separator paper, ensuring that the separator paper is placed alone in the paper stacking area 4, avoiding placing the battery cells in the paper stacking area 4.

[0038] Further, the plasma air knife can be arranged in the vertical direction on the ascending path after the film suction device 20 absorbs the battery cell from the overlapping area 2 and the paper suction device 30 absorbs the separator paper from the overlapping area 2. Specifically, the plasma air knife can be located below the sliding frame 10 in the vertical direction. In this way, the plasma air knife can be blown after the film suction device 20 absorbs the battery cell from the overlapping area 2 and the paper suction device 30 absorbs the separator paper from the overlapping area 2.

[0039] More specifically, Figure 1 As shown, the slicing device 1 further includes a static-eliminating plasma generator 50, which is suitable for generating static-eliminating plasma, and the plurality of plasma air knives are all connected to the static-eliminating plasma generator 50. In this way, static-eliminating plasma can be centrally generated by the static-eliminating plasma generator 50, and then distributed to the plasma air knives to blow the static-eliminating plasma toward the battery slices.

[0040] Furthermore, the plasma air knife is rotatably arranged on the bracket via a universal joint, so that the blowing angle of the plasma air knife can be adjusted to ensure the best separation effect.

[0041] Figure 1 FIG. 1 shows a slicing device 1 according to some examples of the present utility model. Figure 1As shown, the sliding frame 10 is movable between a first position and a second position. When the sliding frame 10 is in the first position, the film suction device 20 is located above the overlapping area 2 and the paper suction device 30 is located above the paper stacking area 4. When the sliding frame 10 is in the second position, the film suction device 20 is located above the battery cell conveyor belt 5 and the paper suction device 30 is located above the overlapping area 2. The overlapping area 2 is suitable for stacking alternately stacked battery cells and separators, the paper stacking area 4 is suitable for stacking separators, and the battery cell conveyor belt 5 is suitable for conveying battery cells 2. Figure 1 The sliding frame 10 is located at the second position. Thus, when the sliding frame 10 is located at the first position, the sheet suction device 20 and the paper suction device 30 can simultaneously suck the battery sheet and release the separator paper, and when the sliding frame 10 is located at the second position, the sheet suction device 20 and the paper suction device 30 can simultaneously release the battery sheet and suck the separator paper, thereby shortening the moving stroke of the sliding frame 10 and improving the sheet separation efficiency.

[0042] Specifically, Figure 1 As shown, there are multiple static electricity removal devices 40, and the multiple static electricity removal devices 40 are respectively located at the four corners of each overlapping area 2 in the horizontal direction. In this way, static electricity can be eliminated from the battery cell in different directions, further improving the static electricity elimination effect.

[0043] In addition, when the static electricity removal device 40 is a plasma air knife, by blowing at the four corners of the overlapping area 2, not only can the separation effect in the case of suction film with paper be further improved, but also the separation effect between the separator paper and the battery cell in the case of suction film with paper can be improved by blowing at different angles.

[0044] More specifically, Figure 1 As shown, the slicing device 1 further includes slicing air knives 60, which are arranged at intervals around the overlapping area 2. Specifically, there are multiple slicing air knives 60 and they are arranged at intervals along the circumference of the overlapping area 2. In this way, the slicing air knives 60 can be used to blow to promote the separation of the battery sheet and the separator paper.

[0045] In addition, when the static electricity removal device 40 is a plasma air knife, two consecutive blows are achieved through cooperation with the plasma air knife, thereby further improving the separation effect of the battery cell and the separator paper, especially the separation of the battery cell and the separator paper in the case of suction paper strips.

[0046] Figure 1 FIG. 1 shows a slicing device 1 according to some examples of the present utility model. Figure 1As shown, the slicing device 1 also includes a color detection device 70, which is suitable for detecting the color of the battery cell or separator paper stacked at the top of the overlapping area 2. It can be understood by those skilled in the art that the battery cells and separator paper overlapped at the overlapping area 2 may cause repeated overlapping of two layers of separator paper between two adjacent battery cells or two battery cells between two adjacent layers of separator paper due to misoperation. By setting the color detection device 70, it is possible to determine whether the battery cell or separator paper is stacked above the overlapping area 2 by detecting the color. When repeated overlapping occurs, the sucking device 20 and the sucking device 30 are controlled to suck again. For example, when two layers of separator paper are stacked between two battery cells, after the sucking device 20 and the sucking device 30 suck the battery cell and separator paper in the original order, the top of the overlapping area 2 is still the separator paper. At this time, the color detection device 70 determines that the top of the overlapping area 2 is still the separator paper by color, and controls the sucking device 30 to suck the paper again, and then sucks it according to the original alternating order. This avoids the situation where the battery cells or the separators are repeatedly stacked and the battery cells or the separators are accidentally sucked by the battery cells or the separators because the battery cells or the separators are accidentally sucked by the battery cells or the separators because the battery cells or the separators are accidentally sucked by the battery cells or the separators.

[0047] Advantageously, if Figure 1 As shown, there are multiple sheet suction devices 20 and paper suction devices 30 and they are arranged at intervals on the sliding frame 10. In this way, the battery sheets and separators in multiple overlapping areas 2 can be separated at the same time, thereby improving the overall separation efficiency.

[0048] Specifically, Figure 1 As shown, the paper suction device 30 includes a suction cup bracket 31 and four circular Bernoulli suction cups 32, and the four circular Bernoulli suction cups 32 are arranged at intervals on the suction cup bracket 31. Specifically, the suction cup bracket 31 is X-shaped, and the four circular Bernoulli suction cups 32 are respectively arranged at the four ends of the suction cup bracket 31. This can facilitate the suction of the separator paper, and the separator paper can be sucked at multiple points by using multiple circular Bernoulli suction cups 32 to prevent the separator paper from bending and deforming due to single-point suction.

[0049] The film suction device 20 is a rectangular Bernoulli suction cup, which can facilitate the suction of the battery sheet and make the suction force of the battery sheet more uniform.

[0050] The bracket is provided with a screw rod 81 and a motor 82, the sliding frame 10 is threadedly matched with the screw rod 81, and the screw rod 81 is transmission-connected with the motor 82. The rotation of the motor 82 drives the screw rod 81 to rotate, and the screw rod 81 converts the rotation into the movement of the sliding frame 10 along the axial direction of the screw rod 81 by threading with the sliding frame 10, thereby realizing the movement drive of the sliding frame 10.

[0051] The film suction device 20 is movably mounted on the sliding frame 10 via a cylinder, and the paper suction device 30 is movably mounted on the sliding frame 10 via a cylinder. This makes it easy to independently lift the film suction device 20 and the paper suction device 30.
