[0018] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0019] According to the plasma micro-damage slicing system of the embodiment of the present invention, the plasma micro-damage slicing system includes a box body 1, a plasma cutting mechanism, a splitting mechanism, a storage box 8 and a conveying mechanism. The box body 1 is located on a base, a feed port 11 is arranged on a first side of the box body 1 in a first direction, and a discharge port 12 is arranged on a second side of the box body 1. The plasma cutting mechanism includes a movable seat 2, a plasma generating device and a cooling nozzle 4. The movable seat 2 is slidably connected to the top of the box body 1, the plasma generating device is located on the movable seat 2 and is perpendicular to the movable seat 2, and the cooling nozzle 4 is located on both sides of the plasma generating device and can move relative to the movable seat 2 The splitting mechanism includes a splitting plate 5, a support member 6 and a first push rod 7. The support member 6 is located on the base. The support member 6 is pivotally connected to the splitting plate 5. The telescopic end of the first push rod 7 is pivotally connected to the splitting plate 5. The other end of the first push rod 7 is connected to the support member 6. The two splitting plates 5 are arranged along a first direction. There is a preset spacing between the splitting plates 5 and adjacent splitting plates 5. The storage box 8 is located on the side of the base adjacent to the discharge port 12 to accommodate the cut battery cells. The conveying mechanism includes a conveyor belt 9. The conveyor belt 9 is located between the splitting mechanism and the storage box 8. The conveyor belt 9 is used to transport the cut materials to the storage box 8. The plasma cutting mechanism cuts and passivates the battery cells. The cooling nozzles 4 are arranged on both sides to cool and protect the battery cells. The splitting mechanism fixes the battery cells to be cut. After the battery cells are cut to a certain extent, they can be split by the cooperation of the first push rod 7 and the splitting plate 5 to improve the cutting effect and processing efficiency. The conveyor belt 9 of the conveying mechanism sends the processed battery cells into the storage box 8 for centralized storage. The storage box 8 leaves through the discharge port 12 of the box body 1 to facilitate the removal of the battery cells.

[0020] The plasma minimal-damage slicing system according to the embodiment of the present invention has the advantages of high processing efficiency and good cutting quality.

[0021] In some embodiments, a collection box 10 is disposed below the splitting mechanism, and the collection box 10 is used to collect the debris on the splitting plate 5 and the coolant of the cooling nozzle 4 .

[0022] Specifically, the collection box 10 can be equipped with a filter to separate the coolant and solid debris for easy recycling and subsequent treatment. On the one hand, it reduces the waste of coolant, and on the other hand, it can maintain a clean environment. The setting of the collection box 10 can effectively collect the debris generated during the splitting process and the coolant of the cooling nozzle 4, keep the working environment clean, reduce pollution, and also facilitate the recycling and reuse of waste materials.

[0023] In some embodiments, a slide groove extending along the first direction is provided on the base, and the collection box 10 is slidably connected to the slide groove. A second push rod is arranged at one end of the slide groove adjacent to the support member 6, and the telescopic end of the second push rod is connected to the collection box 10 to push the collection box 10 out of the discharge port 12.

[0024] Specifically, the chute extends along the first direction to guide the collection box 10, and the second push rod can be an electric push rod to push the collection box 10 to make reciprocating linear motion along the chute, so as to realize the automatic pushing operation. Through the design of the chute and the second push rod, the collection box 10 can be quickly pushed out and emptied, thereby improving the automation degree and operation efficiency of the system.

[0025] Optionally, a pressure sensor is provided in the collection box 10 . When the number of battery cells in the collection box 10 reaches a preset number, the pressure detected by the pressure sensor exceeds a preset value, the pressure sensor sends a signal, and the second push rod pushes the collection box 10 to move toward the discharge port 12 .

[0026] In some embodiments, the second direction is perpendicular to the first direction, and a plurality of moving seats 2 and splitting plates 5 are arranged along the second direction to cut a plurality of battery cells at the same time.

[0027] Specifically, a plasma generator and two cooling nozzles 4 are provided on each mobile seat 2, so that the cutting process can be carried out in parallel. The simultaneous operation of multiple mobile seats 2 can improve efficiency. The simultaneous processing of multiple battery cells can be achieved, the processing cycle of a single battery cell can be shortened, and the overall production capacity can be improved.

[0028] The plasma generator includes a gas source plasma power supply, a gas source and a rod-shaped electrode. The plasma power supply can be a DC power supply, an AC power supply, a radio frequency power supply or a pulse power supply. The plasma can oxidize and passivate the cross section to produce a silicon oxide passivation layer, which can neutralize the dangling bonds and provide protection for the exposed silicon at the cross section, thereby reducing the cutting damage of the battery cell and preventing power loss.

[0029] In some embodiments, the splitting mechanism further includes an angle sensor, which is arranged on the splitting plate 5 to monitor the angle change between the splitting plate 5 and the support 6 .

[0030] Specifically, the angle sensor can accurately measure the angle of the split plate 5 relative to the support 6 to ensure cutting accuracy, and can automatically adjust the position of the split plate 5. The use of the angle sensor helps to accurately control the splitting process, ensure the consistency of cutting quality, and reduce the reduction of cutting quality caused by angle deviation.

[0031] In some embodiments, a limit frame is provided on the split plate 5 , and the height of the limit frame is greater than or equal to the thickness of the battery cell to constrain the position of the battery cell.

[0032] Specifically, the limiting frame can effectively constrain the position of the battery cell, prevent the battery cell from being displaced relative to the split plate 5 during the cutting process, and improve the cutting accuracy. The battery cell can be arranged in a fixed position by contacting the limiting frame, reducing the involvement of the positioning device.

[0033] In some embodiments, a plurality of vacuum adsorption holes are equidistantly arranged on the split plate 5 , and the vacuum adsorption holes are used to fix the battery cells by negative pressure adsorption.

[0034] Specifically, the vacuum adsorption holes can be controlled by partitioning to accommodate cells of different sizes and shapes. The use of vacuum adsorption holes can stably fix the cell, prevent vibration and displacement during the cutting process, and improve the cutting quality. When the cell needs to be loosened, air can be supplied through the vacuum adsorption holes to lift the cell with the help of airflow, reducing the contact between the cell and the split plate 5.

[0035] In some embodiments, a slide rail is provided on the movable seat 2 , and the cooling nozzle 4 is slidably connected to the slide rail via a slider to adjust the distance of the cooling nozzle 4 relative to the plasma generating device 3 .

[0036] Specifically, the slide rail and the slider cooperate to ensure the precise positioning of the cooling nozzle 4. The position of the cooling nozzle 4 can be adjusted according to the cutting requirements, optimizing the cooling effect, improving the cutting quality and the service life of the equipment. The cooling nozzle 4 can be used to spray the passivation liquid and the cleaning liquid on the surface of the battery cell to form a protective film on the surface of the battery cell to prevent oxidation and other chemical reactions.

[0037] In some embodiments, the cooling nozzle 4 is pivotally connected to a slider to adjust the spraying angle.

[0038] Specifically, the cooling nozzle 4 can be rotatably connected to the slider using a ball joint or other adjustable joints to achieve multi-angle adjustment of the nozzle. Adjusting the spray angle can more effectively cool the cutting area and improve the quality of the cutting edge.

[0039] In some embodiments, a pressure sensor is disposed on one end of the split plate 5 away from the adjacent split plate 5 , and the pressure sensor abuts against the battery cell to determine the position of the battery cell.

[0040] Specifically, the pressure sensor can be located on the inner side of the limit frame on the split plate 5. When the battery cell is pushed onto the split plate 5, the battery cell abuts and touches the pressure sensor. At this time, the battery cell abuts against the inner side of the limit frame, and the battery cell reaches the preset processing position. The pressure sensor sends a signal, and subsequent processing can be performed. The use of the pressure sensor can accurately determine the position of the battery cell, ensure the accuracy of the cutting starting point, and improve the cutting efficiency and quality.
