Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0032] In the description of the present application, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear to indicate an orientation or position relationship, it is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the utility model product is usually placed when used. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0033] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0034] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

[0035] The inventor of the present application has found that the conventional pole piece feeding and cutting technology requires the pole piece to be stopped before cutting, which has the defect of low cell production efficiency. The embodiment of the present application provides a pole piece processing device, which can at least solve this technical problem.

[0036] Please refer to Figure 1 The electrode processing equipment provided in the embodiment of the present application includes a basic mounting plate 1, a sheet feeding drive device 2, a sheet feeding device 3, a cutting drive device 4 and a cutting device 5. The sheet feeding drive device 2 and the cutting drive device 4 are both arranged on the basic mounting plate 1. The sheet feeding drive device 2 is connected to the sheet feeding device 3, and the sheet feeding drive device 2 is used to drive the sheet feeding device 3 to move in a preset direction; the cutting drive device 4 is connected to the cutting device 5, and the cutting drive device 4 is used to drive the cutting device 5 to move in a preset direction.

[0037] It should be noted that the sheet feeding device 3 can clamp and transport the electrode under the drive of the sheet feeding drive device 2, and the cutting device 5 can cut the electrode during movement under the drive of the cutting drive device 4; the sheet feeding device 3 and the cutting device 5 can both move in the same preset direction. When the movement speed and direction of the sheet feeding device 3 and the cutting device 5 are consistent, the sheet feeding device 3 and the cutting device 5 remain relatively still, and the electrode can be cut by the cutting device 5 at this time.

[0038] When the electrode needs to be cut, the feeding device 3 is driven to move in a preset direction by the feeding driving device 2, and the cutting device 5 is also driven to move in the preset direction by the cutting driving device 4, so that the movement speed and movement direction of the feeding device 3 and the cutting device 5 are consistent, and the feeding device 3 and the cutting device 5 remain relatively still. At this time, the feeding device 3 transports the electrode, and at the same time, the cutting device 5 can cut the electrode, without stopping the transportation of the electrode, thereby improving the production efficiency of the battery cell.

[0039] It can be understood that the electrode processing equipment of this embodiment can also drive the cutting device 5 to move to the cutting position through the cutting drive device 4, at which time the movement of the cutting device 5 and the feeding device 3 is stopped, and the cutting of the electrode is completed when the cutting device 5 and the feeding device 3 are in a static state. However, the efficiency of electrode cutting is higher when the movement speed and movement direction of the feeding device 3 and the cutting device 5 are consistent.

[0040] Please refer to Figure 2In this embodiment, the film feeding drive device 2 includes a film feeding drive motor 21, a film feeding mounting plate 22 and a film feeding screw mechanism 23; the film feeding drive motor 21 is arranged on the basic mounting plate 1, the film feeding screw mechanism 23 is connected to the film feeding drive motor 21, the film feeding mounting plate 22 cooperates with the film feeding screw mechanism 23, and the film feeding device 3 is arranged on the film feeding mounting plate 22.

[0042] During the process of conveying the electrode, the feeding drive motor 21 is started, the feeding drive motor 21 drives the feeding screw 231 to rotate, and the feeding screw 231 drives the feeding mounting plate 22 to slide on the first slide rail 232, so that the feeding device 3 holding the electrode moves with the feeding mounting plate 22.

[0043] Please refer to Figure 3 , Figure 4 In this embodiment, the film feeding device 3 includes a support frame 31, a driving cylinder 32, a first clamping roller 33 and a second clamping roller 34. The support frame 31 is arranged on the film feeding mounting plate 22, the driving cylinder 32 and the first clamping roller 33 are both arranged on the support frame 31, and the driving cylinder 32 is connected to the second clamping roller 34 to drive the second clamping roller 34 to approach or move away from the first clamping roller 33.

[0044] A rectangular through hole is provided on the support frame 31 to allow the pole piece to pass through; the driving cylinder 32 is arranged on one side of the support frame 31, and the driving cylinder 32 is connected to the second clamping roller 34. When the driving cylinder 32 drives the second clamping roller 34 to approach the first clamping roller 33, the second clamping roller 34 cooperates with the first clamping roller 33 to clamp the pole piece; when the pole piece needs to be loosened, the driving cylinder 32 drives the second clamping roller 34 away from the first clamping roller 33; both the first clamping roller 33 and the second clamping roller 34 are equipped with bearings.

[0047] In this embodiment, the sheet feeding device 3 also includes a first guide plate 36 and a second guide plate 37 that are arranged opposite to each other.

[0049] The film feeding device 3 also includes a guide bar 38 and two first guide shafts 39. The two first guide shafts 39 pass through the support frame 31 and are connected to the guide block 35 to guide the guide block 35. The guide bar 38 simultaneously connects the two first guide shafts 39 to maintain the stability of the first guide shafts 39.

[0050] After the first clamping roller 33 and the second clamping roller 34 clamp the pole piece and move it to the winding position for winding, the winding needle starts to wind the pole piece, the second clamping roller 34 moves away from the first clamping roller 33, and the feeding device 3 returns to the starting position under the reverse drive of the feeding drive motor 21; when a cycle of battery cell winding is about to end, the feeding device 3, driven by the feeding drive motor 21, clamps the pole piece again and moves forward in the same direction and speed as the pole piece, until the pole piece is transported to the cutting position by the feeding device 3. When the feeding device 3 and the cutting device 5 are relatively stationary, the pole piece is cut by the cutting device 5. At this time, the first clamping roller 33 and the second clamping roller 34 still need to keep clamping the pole piece to prevent the problem of pole piece rebounding when the battery cell winding is finished.
