[0035] Please refer to figure 1 As shown, the pole piece cutter mechanism 100 provided in this embodiment is applied to a cell production device. The pole piece cutter mechanism 100 greatly reduces the powder dropping rate of the pole piece by processing the crease marks of the pole piece before stacking, and can improve the overlapping accuracy of the stack, thereby improving the quality of the battery cell.

[0036] The pole piece cutter mechanism 100 provided in this embodiment includes a frame 110, a crease assembly 130 and a cutting assembly 150. The crease assembly 130 and the cutting assembly 150 are respectively arranged on the frame 110, and the frame 110 is installed in practical applications. Assembled and fixed with other working mechanisms of the cell production device, the frame 110 is used to carry pole pieces, and the pole pieces move along a preset direction on the frame 110 under the action of the pole piece conveying mechanism.

[0053] This embodiment provides a cell production device, including a pole piece conveying mechanism, a stacking mechanism, and the pole piece cutter mechanism 100 provided in the first embodiment.

[0054] The pole piece cutter mechanism 100 avoids multiple cutting of the pole piece, greatly reduces the powder dropping rate of the pole piece, and forms multiple creases on the pole piece, which is convenient for the lamination process of the lamination mechanism , which improves the overlapping accuracy of the laminations, thereby improving the quality of the output cells. Therefore, the cell production device provided in this embodiment can produce cells with higher quality.

Abstract

The invention discloses a pole piece cutter mechanism and a battery cell production device, and relates to the technical field of battery cell production. The pole piece cutter mechanism comprises a rack, a creasing assembly and a cutting assembly, the creasing assembly and the cutting assembly are arranged on the rack, and the rack is used for bearing a pole piece; the creasing assembly is used for creasing the pole piece once every time the pole piece moves by a preset piece width relative to the rack; and the cutting assembly is used for cutting off the pole piece when the pole piece movesby a preset number of preset piece widths relative to the rack. According to the pole piece cutter mechanism, the pole piece can be creased, so that the powder falling rate of the pole piece is reduced to a great extent, the lamination overlapping precision can be improved, and the quality of the battery cell is further improved.

Description

technical field [0001] The invention relates to the technical field of electric core production, in particular to a pole piece cutter mechanism and an electric core production device. Background technique [0002] At present, the cell production devices on the market are usually equipped with a pole piece cutter mechanism in which a cutter and a driving device are combined. In the actual working process, whenever the pole piece moves a predetermined width relative to the frame, the cutter mechanism cuts off the pole piece once, and the cut pole piece is sent to the diaphragm to be arranged together and laminated. [0003] After the pole piece is completely cut off, the probability of powder falling is very high, and because of the position difference between the cut pole pieces, the overlap accuracy of the lamination is poor, which seriously affects the quality of the battery cell. Contents of the invention [0004] The object of the present invention is to provide a pole...
