[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] See Figure 1 As shown, a sheet-making device with a defect rejection function is illustrated, comprising an unwinding mechanism 1, a slitting mechanism 2, and a rejection mechanism 3 arranged sequentially. The unwinding mechanism 1 is used to unwind battery electrodes, the slitting mechanism 2 is used to slit the unwound battery electrodes, and the rejection mechanism 3 is used to reject defective products after slitting. The rejection mechanism 3 includes a detection component 31 and an execution component 32. The execution component 32 includes a liftable lifting seat 321, a first drive module 322 for driving the lifting seat 321 to move up and down, and a transfer module 323 located on the side of the lifting seat 321. The first drive module 322 is a lifting cylinder, and the transfer module 323 is a robotic arm.

[0030] In this way, the inspection component 31 can inspect the slit battery electrodes, and the execution component 32 can remove the defective products detected by the cooperation of the lifting seat 321 and the robotic arm, so as to improve the quality of the produced batteries.

[0031] Specifically, after the battery electrode unwinding mechanism 1 unwinds, the slitting mechanism 2 cuts the unwound battery electrode into small pieces. Then, the detection component 31 detects the small pieces of battery electrode. If the detected piece is defective, the lifting seat 321 lifts the defective piece upwards, and then the robotic arm grabs the defective piece and moves it outwards.

[0032] In this embodiment, the rejection mechanism 3 further includes a conveying component 33. The conveying direction of the conveying component 33 is the same as that from the unwinding mechanism 1 to the slitting mechanism 2. The front end of the conveying component 33 is located close to the slitting mechanism 2, the execution component 32 is located at the rear end of the conveying component 33, and the detection component 31 is located between the slitting mechanism 2 and the execution component 32. After being output from the slitting mechanism, the slit battery electrode sheets arrive at the conveying component 33. Subsequently, the conveying component 33 can quickly convey the battery electrode sheets through the detection component 31 and the execution component 32, effectively improving the rejection efficiency of defective products.

[0033] The conveying assembly 33 includes two parallel belt conveyors with a gap between them, and the lifting seat 321 is housed in the gap. The two belt conveyors can support the two sides of the battery electrode respectively, so as to give way to the lifting seat 321 and prevent the conveying assembly 33 from interfering with the lifting of the lifting seat 321.

[0034] In this embodiment, a robotic arm is positioned to the side of one of the belt conveyors, and a collection box 324 is also provided to the side of the belt conveyor. The collection box 324 and the robotic arm are arranged along the conveying direction of the conveying assembly 3. After the lifting seat 321 lifts the defective product upwards, the robotic arm can transfer the defective product to the collection box 324 for subsequent processing.

[0035] In this embodiment, the detection component 31 includes a camera suspended directly above the conveying component 33 and a controller (not shown in the figure), which is a PLC controller. When the slit battery electrode sheets are conveyed below the camera, the camera can take pictures of the battery electrode sheets and upload the pictures to the controller. As the battery electrode sheets continue to be conveyed to the execution component 32, the controller judges the images. If the images are judged to be defective, the controller controls the execution component 32 to remove the defective products that have arrived.

[0036] In this embodiment, the slitting mechanism 2 includes a lower cutting seat 21, an upper cutting seat 22 disposed above the lower cutting seat 21, a slide 25 movably disposed at the bottom of the upper cutting seat 22, a third drive module 26 for driving the slide 25 to translate, a cutter 23 movably disposed on the slide 25, and a second drive module 24 for driving the cutter 23 to move up and down. A slitting channel is formed between the upper cutting seat 22 and the lower cutting seat 21. The extending direction of the slitting channel is the same as the conveying direction of the conveying component 33. The translating direction of the slide 25 is perpendicular to the conveying direction of the conveying component 33. The cutter 23 is circular and rotatably connected to the slide 25. The rotation axis of the cutter 23 is the same as the conveying direction of the conveying component 33. The second drive module 24 is a cylinder, and the third drive module 26 is a linear motor.

[0037] A cutting groove 27 is also provided on the top of the lower cutting seat 21. The extending direction of the cutting groove 27 is the same as the translation direction of the slide 25. The projection of the cutter 23 on the lower cutting seat 21 coincides with the cutting groove 27. The cutter 23 can cooperate with the cutting groove 27 to cut the battery electrode sheets, effectively improving the cutting accuracy.

[0038] In this embodiment, the unwinding mechanism 1 includes an unwinding frame 13, an unwinding roller 11 rotatably mounted on the unwinding frame 13, and a fourth drive module 12 for driving the unwinding roller 11 to rotate. The fourth drive module 12 is a motor, and the extension direction of the rotation axis of the unwinding roller 11 is perpendicular to the direction from the unwinding mechanism 1 to the slitting mechanism 2.

[0039] In this embodiment, a guiding mechanism 4 is also provided between the unwinding mechanism 1 and the slitting mechanism 2. The guiding mechanism 4 includes a guiding frame 41, two guiding rollers 42 mounted on the guiding frame 41, and a fifth drive module 43 for driving one of the guiding rollers 42 to rotate. The rotation axes of the two guiding rollers 42 are parallel to the unwinding roller 11. The fifth drive module 43 is a motor, and a guiding gap is formed between the two guiding rollers 42. After being unwound from the unwinding roller 11, the battery electrode sheet enters the guiding gap and is conveyed to the slitting mechanism 2 by the two guiding rollers 42.

[0040] The implementation principle of a sheet-making device with defect rejection function according to an embodiment of this application is as follows: the battery electrode sheet is unwound from the unwinding roller 11. During the unwinding process, the battery electrode sheet passes through the slitting mechanism 2. The cutter 23 cuts the battery electrode sheet during its lifting and translating strokes. Then, the conveying component 33 conveys the cut battery electrode sheet forward. The detection component 31 detects the passing battery electrode sheet. If it is detected as a defective product, the execution component 32 rejects the defective product. If it is detected as a qualified product, the conveying component 33 continues to convey the qualified product to the next process.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
