[0002] There are two main methods for making lithium-ion batteries: winding and stacking. In the early production process, the pole piece may have defects such as pores, foreign body shrinkage, exposed foil, uneven coating thickness, etc. Defective pole pieces will cause safety hazards to the battery performance.

[0003] Therefore, defective electrodes will be removed during the production process of the battery cell.

Such a stacking machine cannot adopt a conventional waste removal device. Therefore, the utility model provides a waste removal device to realize the waste removal work of the stacking machine during stacking. Utility Model Content

[0027] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0028] Reference Figure 1-Figure 7, a waste rejection device for a stacking machine, comprising a frame, a cutting mechanism 3, a film feeding robot 4, a detection module and a waste rejection component 5; the cutting mechanism 3 and the film feeding robot 4 are installed on a mounting frame 1 to form an integral structure, and the material strip 7 is cut by the cutting mechanism 3 and transported to the stacking table 8 by the film feeding robot 4. The mounting frame 1 is slidably connected to the frame through an avoidance linear module 2, and the avoidance linear module 2 is used to drive the mounting frame 1 to move forward and backward to avoid the operation of the waste rejection component 5. For details, refer to Figure 2 , Figure 3 , Figure 4 or Figure 5 The avoidance linear module 2 includes a avoidance linear motor 21, a guide rail 22 and a slider 23. The guide rail 22 is installed on the frame, the bottom of the slider 23 is slidably connected to the guide rail 22, and the top of the slider 23 is fixedly connected to the mounting frame 1. The fixed end of the avoidance linear motor 21 is installed on the frame, and the output end of the avoidance linear motor 21 is connected to the mounting frame 1, so that when the avoidance linear motor 21 is running, it drives the support frame to make a linear reciprocating motion, that is, drives the cutting mechanism 3 and the feeding robot 4 to move as a whole. When it is necessary to remove the defective pole piece 9, the avoidance linear motor 21 drives the overall structure to move away from the stacking table 8, thereby providing an avoidance space so that the waste rejection component 5 can extend to take away the defective pole piece 9. After the defective pole piece 9 is removed, the avoidance linear motor 21 drives the overall structure to move toward the stacking table 8 to continue normal stacking work.

[0029] Reference Figure 5 The sheet feeding robot 4 includes a sheet feeding linear module 41, a support arm 42 and a sheet feeding clamp 43. The sheet feeding clamp 43 is installed on the top of the support arm 42. The bottom of the support arm 42 is slidably connected to the mounting frame 1 through the sheet feeding linear module 41. The sheet feeding linear module 41 adopts a linear motor to drive the support arm 42 and the sheet feeding clamp 43 to make a linear reciprocating movement. During normal stacking operation, it is convenient to transport the cut electrode sheets to the stacking table 8, and during scrap rejection operation, it is convenient to transport the defective electrode sheets 9 to the scrap rejection clamp 52 of the scrap rejection component 5.

[0030] Reference Figure 1 or Figure 2 The detection module includes a camera assembly, which includes two cameras 6. The two cameras 6 are installed on the mounting frame 1 and are located directly below the film feeding clamp 43, and the lenses of the cameras 6 face upward and face the pole pieces. The cameras 6 can detect the pole pieces cut by the cutting mechanism 3 and identify whether they have defects.

[0031] In this embodiment, refer to Figure 4-Figure 7The waste rejection component 5 includes a waste rejection claw 52, ​​a lifting cylinder 51 and a waste box 53. The lifting cylinder 51 is arranged in the vertical direction, and the fixed end of the lifting cylinder 51 is installed on the frame. The waste rejection claw 52 is installed on the movable end of the lifting cylinder 51. When the lifting cylinder 51 is extended and retracted, it can drive the waste rejection claw 52 to move up and down. When the waste rejection claw 52 moves upward to a height (material picking position), it can clamp the defective electrode 9 on the film feeding robot 4. When the waste rejection claw 52 moves downward to the waste box 53, it places the defective electrode 9 in the waste box 53.

[0032] Further, see Figure 6 and Figure 7 The waste rejection assembly 5 also includes a guide member 56, which includes a guide sleeve and a guide rod slidably connected to the guide sleeve. The guide sleeve is fixed on the frame. The top of the guide rod is connected to the movable end of the lifting cylinder 51 through a guide plate. The setting of the guide rod facilitates the guidance of the extension and retraction of the lifting cylinder 51 to improve stability.

[0033] Specifically, refer to Figure 6 and Figure 7 The scrap rejection clamp 52 includes two clamping plates 522 and a clamping cylinder 521. The clamping cylinder 521 is installed on the top of the lifting cylinder 51. The clamping cylinder 521 is used to drive the two clamping plates 522 to move closer or farther away, so as to clamp and release the defective electrode piece 9. A notch 531 is provided on the side of the waste box 53 close to the lifting cylinder 51. The scrap rejection clamp 52 can pass through the notch 531 when moving up and down, so as to stably place the defective electrode piece 9 in the waste box 53.

[0034] Reference Figure 6 The waste box 53 is slidably connected to the frame through a linear guide rail 55, and a linear drive unit for driving the waste box 53 to move is provided on the frame. The linear drive unit adopts a push cylinder 54. When the waste rejection jaw 52 clamps the defective pole piece 9 and moves to the point where the pole piece contacts the inner bottom of the waste box 53, the waste rejection jaw 52 releases the defective pole piece 9, and the push cylinder 54 drives the waste box 53 to move away from the waste rejection jaw 52, ​​thereby completely separating the defective pole piece 9 from the waste rejection jaw 52, ​​facilitating the next waste rejection work.

[0035] The waste rejection process of the waste rejection device in this embodiment is as follows: after the camera 6 detects the defective electrode 9, the avoidance linear motor 21 drives the mounting frame 1 to move to the right, so that there is an avoidance space between the cutting mechanism 3 and the sheet feeding manipulator 4 on the mounting frame 1 and the sheet stacking table 8, and then the lifting cylinder 51 drives the waste rejection claw 52 to move upward to the material picking position, and the sheet feeding linear module 41 drives the sheet feeding claw 43 to move and send the defective electrode 9 to the waste rejection claw 52, ​​and the claw cylinder 521 drives the two clamps 522 to close and clamp the defective electrode 9 , then the sheet feeding clamp 43 releases the defective electrode 9 and is driven to retreat by the sheet feeding linear module 41, and then the lifting cylinder 51 drives the waste rejection clamp 52 to move downward until the defective electrode 9 contacts the inner bottom of the waste box 53, and the waste rejection clamp 52 releases the defective electrode 9, and the pushing cylinder 54 drives the waste box 53 to move away from the waste rejection clamp 52, so that the defective electrode 9 is completely separated from the waste rejection clamp 52 and remains in the waste box 53. Finally, the avoidance linear motor 21 drives the mounting frame 1 to move to the left and reset, and continue the normal stacking work.
