[0029] In related technologies, electrode sampling is usually done manually. However, manual sampling methods suffer from low efficiency, large errors, and difficulty in providing real-time feedback, making it difficult to meet the high efficiency and high quality requirements of modern lithium battery production lines. To address these issues, this application provides an automatic electrode sampling structure that enables rapid and automatic sampling of electrodes without affecting subsequent electrode processing.

[0030] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0031] Referring to Figure 1, the automatic electrode sampling structure includes a roller assembly 1, a support assembly 2, two cutter assemblies 3, a first pressure bar 4, a collection mechanism 5, and a labeling machine 6. The roller assembly 1 includes a first roller 11 and a second roller 12, which are driven to rotate by a motor. The roller assembly 1 is used to drive the electrode 9 from the first roller 11 to the second roller 12.

[0032] Referring to Figures 1-3, the support assembly 2 includes a first platform 21, a second platform 22, a docking space 23, and a drive mechanism. The first platform 21 and the second platform 22 are used to support the electrode 9. The electrode 9 can be driven on the upper surfaces of the first platform 21 and the second platform 22. The upper surfaces of the first platform 21 and the second platform 22 are flush. The first platform 21 and the second platform 22 are located between the first roller 11 and the second roller 12. The docking space 23 is located on the side of the second platform 22 facing the first platform 21.

[0033] Referring to Figures 1-3, the drive mechanism can drive the first platform 21 and the second platform 22 to abut against each other, thus covering the docking space 23. Alternatively, the drive mechanism can drive the first platform 21 and the second platform 22 to move away from each other, thereby opening the docking space 23. The drive mechanism can be a cylinder or a lead screw slide module. Two cutting assemblies 3 are located on opposite sides of the docking space 23, respectively. The two cutting assemblies 3 are arranged along the transmission direction of the electrode 9, and are used to cut the electrode 9. When it is necessary to cut the electrode 9, the roller assembly 1 stops transmitting the electrode 9, and the two cutting assemblies 3 cut the electrode 9 on opposite sides of the docking space 23, breaking the electrode 9 into three segments.

[0034] Referring to Figures 1-3, the first pressure rod 4 is located on the side of the docking space 23 near the first guide roller 11. The first pressure rod 4 is located above the first platform 21. The first pressure rod 4 presses the electrode 9 onto the first platform 21 or releases the electrode 9 by lifting and lowering. Specifically, the first pressure rod 4 can be driven by a cylinder or a lead screw slide module to lift and lower. When the first pressure rod 4 rises, it does not contact the electrode 9, and the electrode 9 can move on the first platform 21. When the first pressure rod 4 falls and presses on the electrode 9, it cooperates with the first platform 21 to clamp the electrode 9. At this time, when the first platform 21 covers the docking space 23, the first guide roller 11 rotates, and the electrode 9 moves towards the second platform 22. The first pressure rod 4 can prevent the electrode 9 from lifting. The collecting mechanism 5 is located directly below the docking space 23. The collecting mechanism 5 can collect the electrode 9 samples cut by the cutting assembly 3. The labeling machine 6 is used to bond the two broken electrode 9 sections into one piece.

[0035] Referring to Figures 1-5, in actual operation, the first roller 11 and the second roller 12 work together to drive the electrode 9. When it is necessary to cut the sample for testing, the first roller 11 and the second roller 12 stop rotating, and the electrode 9 stops driving. The first pressure rod 4 descends and presses on the electrode 9, so that a part of the electrode 9 is clamped between the first pressure rod 4 and the first platform 21. The two cutting assemblies 3 cut the electrode 9 on opposite sides of the docking space 23, breaking the electrode 9 into three segments. One segment is on the first roller 11 and the first platform 21, the middle segment is above the docking space 23, and the other segment is... On the second roller 12 and the second platform 22; the middle section of the electrode 9 can be used as a sample to fall down through the docking space 23 and be collected by the collection mechanism 5; the first pressure rod 4 and the first platform 21 clamp the electrode 9 and move it towards the second platform 22 until the first platform 21 and the second platform 22 abut and cover the docking space 23. The labeling machine 6 attaches the electrode 9 on the first platform 21 and the electrode 9 on the second platform 22 together, making the two sections of the electrode 9 become one. Then the first roller 11 and the second roller 12 start to rotate, and the electrode 9 is driven again on the first platform 21 and the second platform 22.

[0036] This application supports the electrode sheet 9 through a first platform 21 and a second platform 22. The docking space 23 is set on the side of the second platform 22 facing the first platform 21. Two cutting assemblies 3 are respectively set on opposite sides of the docking space 23, so that after the electrode sheet 9 is cut by the cutting assemblies 3, it can fall into the collection mechanism 5 through the docking space 23. After the electrode sheet 9 is cut, the first platform 21, in conjunction with the first pressure rod 4 and the first roller 11, moves one end of the electrode sheet 9 to the second platform 22, so that the labeling machine 6 can bond the two broken sections of the electrode sheet 9 into one piece. This ensures that the electrode sheet 9 can continue to complete the next processing step after the sample is collected. The whole process does not require manual intervention, realizing the automated sampling and processing of the electrode sheet 9 sample, and improving the sampling efficiency and processing efficiency of the electrode sheet 9.

[0037] In some embodiments, the drive mechanism can drive the first platform 21 to move or drive the second platform 22 to move. When it is necessary to cover the docking space 23, the drive mechanism drives the first platform 21 and the second platform 22 to close together.

[0038] Referring to Figures 1-4, in some embodiments, the second platform 22 is fixed relative to the collecting mechanism 5, and the driving mechanism drives the first platform 21 to move in the transmission direction of the electrode 9 so that the first platform 21 cuts into or out of the docking space 23; when the driving mechanism drives the first platform 21 to move towards the second platform 22, the first platform 21 abuts against the second platform 22, thereby covering the docking space 23 with the first platform 21, while the second platform 22 remains stationary; the length of the first platform 21 in the transmission direction of the electrode 9 is greater than the length of the docking space 23, ensuring that the first platform 21 can completely cover the docking space 23.

[0039] Referring to Figures 1-4, in some embodiments, the first pressure rod 4 is located directly above the first platform 21. The first pressure rod 4 moves with the first platform 21. Preferably, the first pressure rod 4 is located at the end of the first platform 21 near the second platform 22, thereby ensuring that when the first pressure rod 4 and the first platform 21 clamp the electrode 9 and move towards the second platform 22, the end of the electrode 9 facing the second platform 22 will not tilt up, and the electrode 9 can maintain smooth transmission towards the second platform 22.

[0040] In some embodiments, the first pressure rod 4 does not move with the first platform 21. The first pressure rod 4 can be raised and lowered. Before the first platform 21 moves to the second platform 22, the first pressure rod 4 descends and gently touches the upper surface of the electrode 9. The first pressure rod 4 can limit the electrode 9 to ensure that the electrode 9 does not tilt when it passes the first pressure rod 4.

[0041] Referring to Figures 1-3, the automatic electrode sampling structure also includes a second pressure rod 7, which is located above the second platform 22. The second pressure rod 7 presses the electrode 9 onto the second platform 22 or releases the electrode 9 by lifting and lowering. The second pressure rod 7 can be driven by a cylinder or a lead screw slide module to lift and lower. When it is necessary to cut the sample for testing, the second pressure rod 7 descends and presses on the electrode 9, the first pressure rod 4 descends and presses on the electrode 9, and the cutter assembly 3 then cuts the electrode 9. The second pressure rod 7 can prevent the electrode 9 on the second platform 22 from lifting during the cutting process, thereby ensuring a smooth electrode 9 cutting and sampling process. When the labeling machine 6 glues the two ends of the electrode 9 together, the second pressure rod 7 can also ensure that the electrode 9 on the second platform 22 remains stable.

[0042] Referring to Figures 3-5, the first pressure rod 4 is located on the side of the cutter assembly 3 away from the docking space 23, and the second pressure rod 7 is located on the side of the cutter assembly 3 away from the docking space 23. This ensures that after the cutter assembly 3 cuts the electrode sheet 9, the first pressure rod 4 can still press on the corresponding section of the electrode sheet 9 on the first roller 11 and the first platform 21, and the second pressure rod 7 can still press on the corresponding section of the electrode sheet 9 on the second roller 12 and the second platform. This ensures that during the process of the labeling machine 6 bonding the two sections of electrode sheet 9 together, the first pressure rod 4 can prevent the electrode sheet 9 on the first platform 21 from lifting up, and the second pressure rod 7 can prevent the electrode sheet 9 on the second platform 22 from lifting up.

[0043] Referring to Figures 1-3, in some embodiments, the automatic electrode sampling structure further includes a flipping component 8, which includes a flipping plate and a flipping mechanism. The flipping plate is located at the docking space 23, and the flipping mechanism drives the flipping plate to flip so that the flipping plate cuts into or out of the docking space 23. The flipping mechanism can be a servo electrode or a stepper motor. When the flip plate cuts into the docking space 23, the flip plate supports the electrode 9. When the first roller 11 and the second roller 12 drive the electrode 9, the flip plate can cut into the docking space 23. At this time, the flip plate is between the first platform 21 and the second platform 22. The flip plate, the first platform 21 and the second platform 22 together support the electrode 9 to ensure that the electrode 9 can be driven smoothly. When it is necessary to cut the sample for testing, the flip plate still cuts into the docking space 23. After the cutter assembly 3 cuts the electrode 9, the electrode 9 sample stays on the upper surface of the flip plate until the flip plate flips down and the electrode 9 sample falls down along the flip plate. At this time, the docking space 23 opens and the first platform 21 can move to the docking space 23 to cover the docking space 23.

[0044] Referring to Figures 1-3, the collection mechanism 5 includes a collection box located directly below the docking slot 23. The collection box is used to collect electrode 9 samples that fall from the docking slot 23. After the collection box has collected all the electrode 9 samples, the staff can remove the collection box. Preferably, the collection box is located on the rotation path of the flip plate. When the flip plate cuts out of the docking slot 23, the flip plate enters the collection box. At this time, if there are electrode 9 samples on the flip plate, the electrode 9 samples can slide directly from the flip plate into the collection box, preventing the electrode 9 samples from falling out of the collection box and ensuring the smooth collection process of the electrode 9 samples.

[0045] Referring to Figures 1-5, the labeling machine 6 includes a labeling head 61, which is used to apply adhesive tape. The labeling head 61 is located directly above the junction of the docking space 23 and the second platform 22. The labeling machine 6 is driven to rise and fall by a cylinder or a lead screw slide module. The labeling machine 6 raises and falls so that the labeling head 61 is against or away from the second platform 22. When the first platform 21 abuts against the second platform 22, the docking space 23 is covered. At this time, the end of the electrode 9 on the first platform 21 facing the second platform 22 approaches the end of the electrode 9 on the second platform 22 facing the first platform 21. The labeling machine 6 descends, causing the adhesive tape on the labeling head 61 to abut against the end of the electrode 9 on the first platform 21 facing the second platform 22, and simultaneously, the adhesive tape on the labeling head 61 abuts against the end of the electrode 9 on the second platform 22 facing the first platform 21. The adhesive tape bonds one section of electrode 9 on the first platform 21 and the other section on the second platform 22 together. The labeling machine 6 rises, and the first roller 11 and the second roller 12 rotate. The bonded electrode 9 is driven by the first roller 11 and the second roller 12 and moved towards the second roller 12. The labeling machine 6 bonds the two ends of the cut electrode 9 into one piece, thereby avoiding the cutting assembly 3 from affecting the subsequent processing of the electrode 9.

[0046] Referring to Figures 1, 3, and 6, in some embodiments, the cutter assembly 3 includes a cutter and a translation mechanism. The translation mechanism is connected to the cutter and drives the cutter to translate in a direction perpendicular to the transmission direction of the electrode 9. When the electrode 9 is driven on the first platform 21 and the second platform 22, the cutter can stop on both sides perpendicular to the transmission direction of the electrode 9 to avoid the cutter being in the transmission direction of the electrode 9. When it is necessary to cut the electrode 9, the electrode 9 stops rotating, and the translation mechanism drives the cutter to translate in a direction perpendicular to the transmission direction of the electrode 9, so that the cutter enters the transmission path of the electrode 9 and cuts the electrode 9. The cutter then moves out of the transmission path of the electrode 9, and the first platform 21 can move towards the second platform 22 to cover the docking space 23. This arrangement ensures that the cutter will not interfere with the transmission of the electrode 9 when it stops working.
