[0002] With the growth of the new energy vehicle market and the rapid development of the energy storage field, the market demand for high-performance, high-quality lithium batteries is constantly increasing. This is driving the development of electrode rolling technology towards higher precision, higher efficiency, and greater intelligence. The main development goals of electrode rolling technology include: improving the uniformity and consistency of rolling, achieving online real-time monitoring and control, improving rolling efficiency, and reducing energy consumption and costs. Among these, the research and application of electrode sampling technology has become particularly important.

[0003] In related technologies, electrode sampling is usually done manually. However, manual sampling methods have problems such as low efficiency and large errors. In addition, after sampling, a lot of time is required to glue the broken electrode pieces together, which affects the production and processing efficiency of the electrode. Utility Model Content

[0004] To address or partially address the problems existing in related technologies, this application provides an electrode sampling device that can quickly and accurately bond broken electrode sheets together, thereby avoiding affecting the production and processing efficiency of electrode sheets.

[0005] This application provides an electrode sampling device, comprising a support assembly, a collection mechanism, a cutting mechanism, and a pressure bar mechanism. The support assembly includes a first platform, a second platform, and a cutting space. The first platform and the second platform are arranged in parallel and are used to support the electrode. The cutting space is located on the side of the second platform facing the first platform. The first platform can cover the cutting space by moving towards the second platform and abutting against it, or move away from it to open the cutting space. The collection mechanism is located directly below the cutting space. The cutting mechanism includes a fixed cutter assembly and a movable cutter assembly. The fixed cutter assembly and the movable cutter assembly are spaced apart and located above the collection mechanism. The fixed cutter assembly and the movable cutter assembly are used to cut the electrode. The movable cutter assembly can adjust the distance between the movable cutter assembly and the fixed cutter assembly by moving towards the fixed cutter assembly. The pressure bar mechanism is located above the first platform and can press the electrode onto the first platform or release the electrode by raising and lowering it.

[0006] Furthermore, the second platform is fixed relative to the collecting mechanism, and the first platform moves back and forth toward the second platform so that the first platform cuts into or out of the cutting space.

[0007] Furthermore, the pressure bar mechanism includes a first pressure bar, which is located directly above the first platform and moves as the first platform moves.

[0008] Furthermore, the fixed cutter assembly is located on the side of the movable cutter assembly closer to the first pressure bar.

[0009] Furthermore, the pressure bar mechanism also includes a second pressure bar, which is located above the second platform. The second pressure bar presses the electrode onto the second platform or releases the electrode by lifting and lowering.

[0010] Furthermore, the second pressure bar is located on the side of the fixed cutter assembly away from the first platform.

[0011] Furthermore, the collection mechanism includes a collection box located directly below the cutting space.

[0012] Furthermore, the fixed cutter assembly includes a first upper cutter and a first lower cutter. The first upper cutter is located above the cutting space, and the first lower cutter is located below the cutting space. The cutting edges of the first upper cutter and the first lower cutter are arranged facing each other. The first upper cutter and the first lower cutter move towards each other to cut the electrode sheet.

[0013] Furthermore, the movable cutter assembly includes a second upper cutter and a second lower cutter. The second upper cutter is located above the cutting space, and the second lower cutter is located below the cutting space. The cutting edges of the second upper cutter and the second lower cutter are arranged facing each other. The second upper cutter and the second lower cutter cut each other to cut the electrode sheet by moving towards each other.

[0014] Furthermore, the cutting mechanism also includes a drive component connected to the movable cutter assembly, which drives the movable cutter assembly to move toward the fixed cutter assembly.

[0015] The technical solution provided in this application can include the following beneficial effects: the electrode sheet is supported by a first platform and a second platform, the cutting space is set on the side of the second platform facing the first platform, and the fixed cutter assembly and the movable cutter assembly are set above the collection mechanism, so that the electrode sheet can fall directly into the collection mechanism after being cut by the fixed cutter assembly and the movable cutter assembly. After the electrode sheet is cut, the first platform and the pressure bar mechanism clamp the electrode sheet and move it to the second platform, which makes it convenient for workers to use adhesive tape to glue the two broken electrode sheets into one piece, thereby improving the sampling efficiency and processing efficiency of the electrode sheet. Moreover, the clamping of the electrode sheet by the first platform and the pressure bar mechanism can ensure that the two electrode sheets can be accurately glued into one piece, reducing the glued error and ensuring the stable progress of the subsequent processing of the electrode sheet.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] In related technologies, electrode sampling is usually done manually. However, manual sampling methods suffer from low efficiency and large errors. Furthermore, after sampling, a significant amount of time is required to bond the broken electrode pieces together, affecting the production efficiency of the electrode. To address these issues, this application provides an electrode sampling device that can quickly and accurately bond broken electrode pieces together, avoiding any impact on the production efficiency of the electrode.

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

[0031] See Figure 1The electrode sampling device includes a support assembly 1, a collection mechanism 2, a cutting mechanism 3, and a pressure rod mechanism. The electrode sampling device can be installed on the processing line of the electrode 6. Specifically, the processing line of the electrode 6 includes multiple rollers 7, on which the electrode 6 can be driven. The electrode sampling device can be positioned between two adjacent rollers 7. After sampling the electrode 6, the electrode 6 can continue processing on the processing line, or the electrode sampling device can be detached from the processing line of the electrode 6, and the electrode 6 can then proceed to the next processing step on the processing line.

[0032] See Figure 1-4 The support assembly 1 includes a first platform 11, a second platform 12, and a cutting space 13. The first platform 11 and the second platform 12 are arranged in parallel and are used to support the electrode 6. The electrode 6 can move on the upper surfaces of the first platform 11 and the second platform 12. The upper surfaces of the first platform 11 and the second platform 12 are flush. The cutting space 13 is located on the side of the second platform 12 facing the first platform 11. The first platform 11 can move towards the second platform 12 and abut against the second platform 12, so that the cutting space 13 is covered. The first platform 11 can also move away from the second platform 12, thereby opening the cutting space 13.

[0033] See Figure 1-3 The collection mechanism 2 is located directly below the cutting space 13, and can collect the electrode sheet 6 samples cut by the cutting mechanism 3. The cutting mechanism 3 includes a fixed cutter assembly 31 and a movable cutter assembly 32, which can be arranged along the transmission direction of the electrode sheet 6. The fixed cutter assembly 31 and the movable cutter assembly 32 are spaced apart and are located above the collection mechanism 2. The fixed cutter assembly 31 and the movable cutter assembly 32 are used to cut the electrode sheet 6. When it is necessary to cut the electrode sheet 6, the roller 7 stops transmitting the electrode sheet 6, and the fixed cutter assembly 31 and the movable cutter assembly 32 cut the electrode sheet 6 into three segments.

[0034] See Figure 1 and Figure 6The movable cutter assembly 32 moves toward the fixed cutter assembly 31 to adjust the distance between the movable cutter assembly 32 and the fixed cutter assembly 31. The operator can adjust the distance according to the required cutting size of the electrode 6. A smaller distance results in a smaller electrode sample. In some embodiments, the cutting mechanism 3 further includes a drive assembly connected to the movable cutter assembly 32, which drives the movable cutter assembly 32 toward the fixed cutter assembly 31. The drive assembly can be a cylinder or a lead screw slide module. In some embodiments, the electrode sampling device includes a first guide rail extending horizontally. The movable cutter assembly 32 is mounted on the first guide rail, which extends toward the fixed cutter assembly 31. The operator can push the movable cutter assembly 32 toward the fixed cutter assembly 31 to adjust the distance between the two assemblies.

[0035] See Figure 1-4 The pressure rod mechanism is located above the first platform 11. The pressure rod mechanism presses or releases the electrode 6 onto the first platform 11 by lifting and lowering. Specifically, the pressure rod mechanism can be driven by a cylinder or a lead screw slide module to lift and lower. The pressure rod mechanism can be magnetically attracted to the first platform 11, or it can be mechanically clamped to press the electrode 6 onto the first platform 11. When the pressure rod mechanism rises, it does not contact the electrode 6, and the electrode 6 can be driven on the first platform 11. When the pressure rod mechanism falls and presses onto the electrode 6, it cooperates with the first platform 11 to clamp the electrode 6. At this time, the roller 7 can rotate to drive the electrode 6. The first platform 11, in conjunction with the pressure rod mechanism, can drive the electrode 6 on the first platform 11 to move towards the second platform. During this process, the pressure rod mechanism can prevent the electrode 6 from tilting.

[0036] See Figure 1-4 In some embodiments, the electrode sampling device includes a driving mechanism that can drive the first platform 11 and the second platform 12 to abut against each other, thereby covering the cutting space 13. Alternatively, the driving mechanism can drive the first platform 11 and the second platform 12 to move away from each other, thereby opening the cutting space 13. The driving mechanism can be a cylinder or a lead screw slide module. In some embodiments, the electrode sampling device includes a second guide rail that extends horizontally. The first platform 11 is mounted on the second guide rail, which extends toward the second platform 12. An operator can push the first platform 11 toward the second platform 12, so that the cutting space 13 is wholly or partially covered by the first platform 11.

[0037] See Figure 1-5In actual operation, the roller 7 drives the electrode sheet 6. When it is necessary to cut the sample for testing, the roller 7 stops rotating, and the electrode sheet 6 stops driving. The pressure bar mechanism descends and presses on the electrode sheet 6, so that part of the electrode sheet 6 is clamped between the pressure bar mechanism and the first platform 11. The moving cutter assembly 32 and the fixed cutter assembly 31 cut the electrode sheet 6, breaking it into three segments. One segment is on the first platform 11, the middle segment is between the moving cutter assembly 32 and the fixed cutter assembly 31 and is in the cutting gap 13, and the other segment is on the second platform 12. The middle segment of the electrode sheet 6 can be used as... The sample falls down through the cutting gap 13 and is collected by the collection mechanism 2. Then, the pressure bar mechanism and the first platform 11 clamp the electrode 6 and move it to the second platform 12 until the first platform 11 and the second platform 12 meet and cover the cutting gap 13. The staff then use adhesive tape to stick the electrode 6 on the first platform 11 and the electrode 6 on the second platform 12 together, making the two electrode 6 into one piece. Then, the staff removes the electrode sampling device from the electrode processing line, the roller 7 starts to rotate, and the electrode 6 is driven back on the first platform 11 and the second platform 12.

[0038] This application supports the electrode sheet 6 via a first platform 11 and a second platform 12. The cutting space 13 is set on the side of the second platform 12 facing the first platform 11. The fixed cutter assembly 31 and the movable cutter assembly 32 are set above the collection mechanism 2, so that the electrode sheet 6 can fall directly into the collection mechanism 2 after being cut by the fixed cutter assembly 31 and the movable cutter assembly 32. After the electrode sheet 6 is cut, the first platform 11 and the pressure bar mechanism clamp the electrode sheet 6 and move it to the second platform 12. This makes it convenient for workers to use adhesive tape to glue the two broken pieces of the electrode sheet 6 into one piece, which improves the sampling efficiency and processing efficiency of the electrode sheet 6. Moreover, the clamping of the electrode sheet 6 by the first platform 11 and the pressure bar mechanism can ensure that the two pieces of the electrode sheet 6 can be accurately glued into one piece, reducing the glued error and ensuring the stable progress of the subsequent processing of the electrode sheet 6.

[0039] In some embodiments, the drive mechanism can drive the first platform 11 to move or drive the second platform 12 to move. When it is necessary to cover the cutting gap 13, the drive mechanism drives the first platform 11 and the second platform 12 to close together.

[0040] In some embodiments, the worker can push the first platform 11 to move, or push the second platform 12 to move. When it is necessary to cover the cutting gap 13, the worker can push the first platform 11 to move towards the second platform 12, while the second platform 12 moves towards the first platform 11, so that the first platform 11 and the second platform 12 are closed together.

[0041] See Figure 1 and Figure 4In some embodiments, the second platform 12 is fixed relative to the collecting mechanism 2, and the first platform 11 moves back and forth toward the second platform 12 so that the first platform 11 cuts into or out of the cutting space 13; specifically, when the driving mechanism or a person can drive the first platform 11 to move toward the second platform 12, the first platform 11 and the second platform 12 abut against each other, so that the first platform 11 covers the cutting space 13, while the second platform 12 remains stationary.

[0042] See Figure 1-3 In some embodiments, the pressure bar mechanism includes a first pressure bar 4, which is located directly above the first platform 11. The first pressure bar 4 moves with the first platform 11. Preferably, the first pressure bar 4 is located at the end of the first platform 11 near the second platform 12, thereby ensuring that when the first pressure bar 4 and the first platform 11 clamp the electrode 6 and move towards the second platform 12, the end of the electrode 6 facing the second platform 12 will not tilt up, and the electrode 6 can maintain smooth transmission towards the second platform 12.

[0043] See Figure 1-3 In some embodiments, the first pressure rod 4 does not move with the first platform 11. The first pressure rod 4 can be raised and lowered. Before the first platform 11 moves to the second platform 12, the first pressure rod 4 descends and gently touches the upper surface of the electrode 6. The first pressure rod 4 can limit the electrode 6 to ensure that the electrode 6 does not tilt when passing the first pressure rod 4.

[0044] See Figure 1 The fixed cutter assembly 31 is located on the side of the movable cutter assembly 32 near the first pressure rod 4. Specifically, the first platform 11 and the second platform 12 are arranged sequentially along the transmission direction of the electrode 6, and the fixed cutter assembly 31 and the movable cutter assembly 32 are arranged sequentially along the transmission direction of the electrode 6.

[0045] See Figure 1-4 The pressure bar mechanism also includes a second pressure bar 5, which is located above the second platform 12. The second pressure bar 5 presses or releases the electrode 6 onto the second platform 12 by lifting and lowering. Specifically, the second pressure bar 5 can be magnetically attached to the second platform 12, or it can be mechanically clamped to press the electrode 6 onto the second platform 12. The second pressure bar 5 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 bar 5 descends and presses on the electrode 6, the first pressure bar 4 descends and presses on the electrode 6, and the fixed cutter assembly 31 and the moving cutter assembly 32 then cut the electrode 6. The second pressure bar 5 can prevent the electrode 6 on the second platform 12 from lifting during cutting, thereby ensuring a smooth cutting and sampling process for the electrode 6. The second pressure bar 5 can also ensure that the electrode 6 on the second platform 12 remains stable.

[0046] See Figure 1The second pressure rod 5 is located on the side of the fixed cutter assembly 31 away from the first platform 11, so that after the moving cutter assembly 32 cuts the electrode sheet 6, the second pressure rod 5 can still press on the corresponding section of the electrode sheet 6 on the second platform 12, ensuring that the second pressure rod 5 can prevent the electrode sheet 6 on the second platform 12 from lifting up during the process of gluing the two sections of electrode sheet 6 together.

[0047] See Figure 1-3 The collection mechanism 2 includes a collection box located directly below the cutting space 13. The collection box is used to collect the electrode sheet 6 samples that fall from the cutting space 13. After the collection box has collected all the electrode sheet 6 samples, the staff can remove the collection box.

[0048] See Figure 1 and Figure 6 The fixed cutter assembly 31 includes a first upper cutter 311 and a first lower cutter 312. The first upper cutter 311 is located above the cutting space 13, and the first lower cutter 312 is located below the cutting space 13. The first lower cutter 312 can be placed inside the collection box. The cutting edges of the first upper cutter 311 and the first lower cutter 312 are arranged facing each other. When the fixed cutter assembly 31 needs to cut the electrode sheet 6, the first upper cutter 311 and the first lower cutter 312 move towards each other, so that the cutting edge of the first upper cutter 311 abuts against the upper surface of the electrode sheet 6, and the cutting edge of the first lower cutter 312 abuts against the lower surface of the electrode sheet 6. The first upper cutter 311 and the first lower cutter 312 cooperate to cut the electrode sheet 6. In some embodiments, the first upper cutter 311 is driven to rise and fall by a cylinder or a lead screw slide module, and the first lower cutter 312 is driven to rise and fall by a cylinder or a lead screw slide module. In some embodiments, the structure of the first upper cutter 311 and the first lower cutter 312 is similar to that of scissors. The operator closes the first upper cutter 311 and the first lower cutter 312 so that the first upper cutter 311 and the first lower cutter 312 cooperate to cut the electrode sheet 6.

[0049] See Figure 1 and Figure 6The movable cutter assembly 32 includes a second upper cutter 321 and a second lower cutter 322. The second upper cutter 321 is located above the cutting space 13, and the second lower cutter 322 is located below the cutting space 13. The second lower cutter 322 can be placed inside a collection box. The cutting edges of the second upper cutter 321 and the second lower cutter 322 face each other. When the movable cutter assembly 32 needs to cut the electrode sheet 6, the second upper cutter 321 and the second lower cutter 322 move towards each other, so that the cutting edge of the second upper cutter 321 abuts against the upper surface of the electrode sheet 6, and the cutting edge of the second lower cutter 322 abuts against the lower surface of the electrode sheet 6. The second upper cutter 321 and the second lower cutter cooperate to cut the electrode sheet 6. In some embodiments, the second upper cutter 321 and the second lower cutter 322 are driven to rise and fall by a cylinder or a lead screw slide module. In some embodiments, the structure of the second upper cutter 321 and the second lower cutter 322 is similar to that of scissors. The operator closes the second upper cutter 321 and the second lower cutter 322 so that the second upper cutter 321 and the second lower cutter 322 cooperate to cut the electrode sheet 6.
