Description

Technical Field

[0001] This utility model relates to the field of lithium battery processing technology, and in particular to an electrode feeding mechanism. This utility model also relates to a cutting device. Background Technology

[0002] Currently, lithium batteries are mainly produced using two methods: winding and stacking. Compared to the winding process, the cells produced by the stacking process have higher energy density and better quality. Therefore, the stacking machine, as a key piece of equipment in the stacking process, plays a decisive role in production efficiency and product quality.

[0003] In existing stacking machines, the sheet production process usually adopts a double-roller feeding and metal die-cutting method. In order to further improve production efficiency and equipment capacity, many machines adopt double-blade or even multi-blade cutting methods for sheet production.

[0004] However, during multi-blade die cutting, the electrode strip is prone to sagging due to the relatively soft anode material. This causes the edges to collide and fold between multiple pairs of rollers, affecting not only the yield of the sheet but also potentially leading to quality problems in subsequent processes. Furthermore, under the requirement of high-speed feeding, the edge of the electrode strip may overshoot due to the angular acceleration direction of the drive roller, frequently causing material blockage. This results in lengthy cleaning times after each blockage, which is not only difficult but also leaves electrode material residue. These residues may cause short circuits in the manufactured cells, significantly reducing equipment uptime and finished product yield, thereby increasing production costs. Utility Model Content

[0005] In view of this, the present invention aims to provide an electrode feeding mechanism that can improve the electrode production yield and reduce production costs.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] An electrode feeding mechanism for conveying electrode strips to be cut or cut electrode sheets, comprising a guiding assembly, a roller conveying assembly and a driving assembly;

[0008] The roller conveying assembly includes a pressure roller and a drive roller arranged opposite each other.

[0009] The material guiding assembly includes a material guiding section disposed between the pressure roller and the drive roller, and an anti-cavity groove disposed vertically on the material guiding section. The material guiding section extends along a preset direction, and the anti-cavity groove is disposed corresponding to the pressure roller and the drive roller.

[0010] The driving assembly includes a first driving part connected to the driving roller. Under the drive of the first driving part, the driving roller can cooperate with the pressure roller to guide the electrode strip or the electrode sheet to move along the preset direction on the material guide.

[0011] Furthermore, the electrode feeding mechanism also includes a worktable; the material guiding component is disposed on the worktable, and the roller conveying component and the first driving unit are both disposed on the worktable via a first base.

[0012] Furthermore, the driving assembly includes a second driving part disposed on the first base, the second driving part being connected to the pressure roller drive, and the second driving part being used to drive the pressure roller to rise and fall.

[0013] Furthermore, the pressure roller is slidably mounted on the first base via a sliding seat assembly.

[0014] Furthermore, the pressure roller is provided with a plurality of roller pressing sections arranged at intervals along its own axial direction, the drive roller is provided with a plurality of drive sections corresponding one-to-one with each of the roller pressing sections, and the clearance groove includes a groove corresponding one-to-one with each of the roller pressing sections and each of the drive sections; and / or, the roller conveying assembly is a plurality of components arranged at intervals along a preset direction, and the clearance groove is a plurality of components arranged one-to-one with each of the roller conveying assemblies.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] The electrode feeding mechanism described in this utility model provides effective support and guidance for the electrode strip through a guide section located between the pressure roller and the drive roller. By setting a clearance groove on the guide section, not only can the drive roller and the pressure roller cooperate to transport the electrode strip, but the guide section can also prevent the electrode strip from sagging during the transport process. This avoids subsequent collisions with the rollers or even over-rushing and clogging of the electrode strip or the finished electrode sheet, thus achieving stable transport of the electrode strip. This can improve the electrode sheet yield and reduce downtime and production costs.

[0017] The worktable provides a robust foundation, facilitating the arrangement and installation of the guiding assembly, roller conveying assembly, and first drive unit within the electrode feeding mechanism. This ensures the stability of the entire electrode feeding mechanism during operation, thereby improving overall reliability. The pressure roller can rise and fall under the action of the second drive unit, allowing for flexible adjustment of the gap between the pressure roller and the drive roller to drive electrode strips of varying thicknesses. Furthermore, the sliding seat assembly guides the lifting and lowering of the pressure roller, ensuring smooth and precise vertical movement.

[0018] Furthermore, the one-to-one correspondence between each roller pressing section and each drive section ensures that the electrode strip or electrode sheet is subjected to uniform pressure and drive during the conveying process, improving processing accuracy and consistency. The design of the clearance groove as multiple slots arranged at intervals allows the guide part to partially support the electrode strip or electrode sheet between two adjacent slots, ensuring continuous support for the electrode strip or electrode sheet during the conveying process, preventing it from sagging or sinking into the slots, thereby improving conveying reliability.

[0019] Another objective of this invention is to provide a cutting device, wherein the cutting device is provided with an electrode feeding mechanism as described above.

[0020] Furthermore, the cutting device also includes a cutting assembly disposed between two adjacent sets of the roller conveying assemblies, the cutting assembly having a cutting unit for cutting the electrode strip.

[0021] Furthermore, the cutting device also includes a worktable; the cutting assembly is mounted on the worktable via a second base, and the cutting blade unit is slidably mounted on the second base.

[0022] Furthermore, the second base is provided with guide holes arranged in the vertical direction, the cutter unit is provided with guide members, and the guide members are slidably disposed in the guide holes; and / or, the cutting assembly includes a third driving part, and the driving end of the third driving part is drivenly connected to the cutter unit.

[0023] Furthermore, the cutting components are multiple sets arranged at intervals along the preset direction.

[0024] The cutting device described in this utility model is equipped with an electrode feeding mechanism as described above. The electrode feeding mechanism can smoothly transport the electrode strip, which helps to reduce cutting errors and improve the quality of the finished electrode.

[0025] Furthermore, the design of guide holes and guide components helps improve the smoothness of the cutting unit's movement and the reliability of cutting, thus facilitating consistent cutting. Simultaneously, the multiple sets of cutting components arranged at intervals along a preset direction improve cutting efficiency and reduce downtime. Attached Figure Description

[0043] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] Example 1

[0045] This embodiment relates to an electrode feeding mechanism that can provide effective support and guidance for the electrode strip 6 or the electrode sheet, preventing the electrode strip 6 or the electrode sheet from sagging during the conveying process, so as to achieve stable conveying of the electrode strip 6.

[0046] In the field of lithium battery production, two main production processes are winding and stacking. Compared with the winding process, the stacking process can produce cells with higher energy density and better quality. Therefore, the stacking machine, as a key piece of equipment for realizing the stacking process, plays a vital role in improving production efficiency and product quality.

[0047] Traditional stacking processes typically rely on roller feeding and die-cutting technology. To improve production efficiency and equipment capacity, modern stacking machines often employ double-blade or multi-blade cutting techniques. However, when handling softer anode materials, such as the anode material (i.e., the electrode strip 6 to be cut, or the cut electrode sheet) during transport, the ends of the electrode strip 6 (or the electrode sheet, which is the electrode sheet to be stacked after being cut from the electrode strip 6, and this article mainly focuses on the electrode strip 6) will gradually sag due to their own weight. This causes the actual running trajectory of the electrode strip 6 to deviate from the designed path, resulting in the edges of the electrode strip 6 colliding or folding between multiple sets of rollers, affecting the electrode yield.

[0048] Furthermore, in order to improve the production efficiency of electrode sheets, a high-speed conveying method for electrode sheet material strip 6 is adopted. In this case, when the drive roller 202 suddenly accelerates or decelerates, the electrode sheet material strip 6 cannot immediately keep up with the speed change of the drive roller 202 due to inertia. This may cause the edge of the electrode sheet material strip 6 to overshoot due to the angular acceleration of the drive roller 202, resulting in the position of the electrode sheet material strip 6 being offset and causing material blockage. Each time material blockage occurs, a lot of time is required for cleaning, and it is difficult to completely remove all residues. These residues may cause short circuits in the battery cells, significantly reducing the equipment uptime and the yield of finished products, thereby increasing production costs.

[0049] These problems not only directly affect the continuity and stability of the production line, but also increase the workload of operators and the cost of equipment maintenance. In order to overcome these challenges, this utility model proposes an electrode feeding mechanism. This mechanism can ensure efficient feeding while providing effective support and guidance for the electrode strip 6 through the guide part 101, preventing the electrode strip 6 from sagging during the conveying process, so as to achieve smooth conveying of the electrode strip 6. Furthermore, when conveying the electrode strip 6 at high speed, since the electrode strip 6 can be conveyed smoothly, it can avoid the electrode strip 6 from clogging, thereby improving the equipment uptime and the yield of finished products.

[0050] In terms of overall structure, such as Figure 1 As shown, the electrode feeding mechanism of this embodiment is used to transport the electrode strip 6 to be cut or the cut electrode sheet, and includes a guiding component 1, a roller conveying component 2 and a driving component 3.

[0051] Furthermore, the roller conveying assembly 2 includes a pressure roller 201 and a drive roller 202 arranged vertically opposite each other. The material guiding assembly 1 includes a material guiding part 101 disposed between the pressure roller 201 and the drive roller 202, and a clearance groove 102 disposed vertically on the material guiding part 101. The material guiding part 101 extends along a preset direction, and the clearance groove 102 is disposed corresponding to the pressure roller 201 and the drive roller 202. The drive assembly 3 includes a first drive part 301 that is driven and connected to the drive roller 202. Under the drive of the first drive part 301, the drive roller 202 can cooperate with the pressure roller 201 to guide the electrode strip 6 or the electrode sheet to move along the preset direction on the material guiding part 101.

[0052] With the above configuration, the guide section 101 located between the pressure roller 201 and the drive roller 202 can provide effective support and guidance for the electrode strip 6. By providing the clearance groove 102 on the guide section 101, not only can the drive roller 202 cooperate with the pressure roller 201 to transport the electrode strip 6, but the guide section 101 can also be used to prevent the electrode strip 6 from sagging during the transport process. This avoids the electrode strip 6 or the electrode sheet from hitting the rollers or even over-punching and blocking the material, so as to achieve stable transport of the electrode strip, thereby improving the electrode sheet production yield and reducing time utilization and production costs.

[0053] Based on the above overall introduction, in detail, in this embodiment, the first driving part 301 can be a driving motor, and the output end of the driving motor is fixedly connected to the end of the driving roller 202. Meanwhile, the material guiding part 101 can be a material guiding plate, which provides a smooth and continuous plane for the electrode strip 6. If necessary, the surfaces of the driving roller 202 and the pressure roller 201 can also be coated with a coating to increase friction or have textures to increase friction created on the surface.

[0054] In specific implementation, the electrode strip 6 is first placed on the guide section 101, and a portion of the electrode strip 6 is made to contact the drive roller 202 (the drive roller 202 can partially pass through the clearance groove 102 so that the top of the drive roller 202 is flush with the guide section 101, thus allowing the electrode strip 6 to contact the top of the drive roller 202). Then, after the first drive section 301 is started, the output end of the first drive section 301 will drive the drive roller 202 to rotate together. Then, the drive roller 202 will apply a driving force to the electrode strip 6 with the cooperation of the pressure roller 201. This driving force will overcome the static friction between the electrode strip 6 and the guide plate and push the electrode strip 6 to move in a preset direction.

[0055] Of course, it should be noted that the descriptions related to direction in this embodiment are only illustrative examples of this embodiment. In specific implementation, the preset direction in this embodiment is the conveying direction of the electrode strip 6 or the electrode sheet. The description of direction in this embodiment varies with the preset direction. That is, each direction in this embodiment is based on the preset direction. Based on the arrangement requirements of the electrode feeding mechanism, the preset direction is generally in the horizontal plane (i.e., the XY plane). At this time, the up and down direction (i.e., the height direction) in this embodiment is the direction perpendicular to the preset direction.

[0056] In this embodiment, as a preferred implementation, such as Figure 1As shown, the electrode feeding mechanism also includes a worktable 4, a guiding assembly 1 is disposed on the worktable 4, and the roller conveying assembly 2 and the first driving unit 301 are both disposed on the worktable 4 via the first base 401. In specific implementation, the guide plate in the worktable 4 and the guiding assembly 1 is on the same plane as the preset direction, and the vertical direction (height direction) can also be understood as the height direction of the worktable 4.

[0057] The worktable 4 provides a robust foundation support, facilitating the arrangement and installation of components such as the guide assembly 1, roller conveyor assembly 2, and first drive unit 301 within the electrode feeding mechanism. This ensures the stability of the entire electrode feeding mechanism during operation, thereby improving overall reliability. Furthermore, the guide unit 101 can be bolted to the worktable 4 for easy adjustment. Simultaneously, both ends of the drive roller 202 in the roller conveyor assembly 2 can be rotatably mounted on the first base 401 via bearings.

[0058] In this embodiment, as a preferred implementation, combined with Figure 2 and Figure 5 As shown, the drive assembly 3 includes a second drive unit 302 disposed on the first base 401. The second drive unit 302 is connected to the pressure roller 201 and is used to drive the pressure roller 201 to rise and fall.

[0059] The main advantage of this setup is that the pressure roller 201 can be raised and lowered under the action of the second drive unit 302. The gap between the pressure roller 201 and the drive roller 202 can be flexibly adjusted according to the electrode strip 6 of different thicknesses. Whether the material is thin or thick, appropriate clamping force can be ensured, thereby achieving stable conveying and driving the electrode strip 6 of different thicknesses to move forward.

[0060] As for the specific structural design of the first base 401, it can be set and adjusted according to the actual installation requirements of the roller conveying assembly 2 and the first drive unit 301. For example, the first base 401 includes a base plate, two first support plates at both ends of the base plate in the length direction, and two second support plates located between the two first support plates on the base plate. Both ends of the drive roller 202 are rotatably mounted on the two second support plates through bearings. The first drive unit 301 can be located on the side of one of the first support plates away from the drive roller 202.

[0061] In practice, there can be two second drive units 302, each mounted on a separate first support plate. The drive ends of each second drive unit 302 are connected to both ends of the pressure roller 201. By connecting independent second drive units 302 to both ends of the pressure roller 201, the descent position of the pressure roller 201 can be easily adjusted, resulting in more uniform pressure applied to the electrode strip 6. This helps avoid problems such as offset, slippage, or damage to the electrode strip 6 caused by insufficient or excessive pressure on one side, and also reduces the risk of deformation of the pressure roller 201. The second drive unit 302 can be any one of a hydraulic cylinder, pneumatic cylinder, or electric push rod.

[0062] See Figure 5 and Figure 6 As shown, in this embodiment, as a preferred implementation, the pressure roller 201 is slidably mounted on the first base 401 via the sliding seat assembly 4011. Here, the sliding seat assembly 4011 guides the lifting and lowering of the pressure roller 201, ensuring that the pressure roller 201 moves smoothly and accurately in the vertical direction.

[0063] In a specific implementation, the aforementioned sliding seat assembly 4011 can be a slide rail mounted on the first base 401 and a slide seat slidably mounted on the slide rail. The second drive unit 302 is mounted on the first base 401 above the slide seat and is drivenly connected to a connecting seat on the slide seat. The end of the pressure roller 201 is rotatably mounted on the connecting seat. Of course, since there are two second drive units 302, the aforementioned sliding seat assembly 4011 is preferably configured as two units corresponding one-to-one with each of the second drive units 302 to ensure the lifting stability of the pressure roller 201.

[0064] Furthermore, in this embodiment, as a preferred implementation, such as Figure 6 As shown, the pressure roller 201 is provided with multiple roller pressing sections arranged at intervals along its own axial direction, the drive roller 202 is provided with multiple drive sections corresponding to each roller pressing section, and the clearance groove 102 includes a groove 1021 that corresponds to each roller pressing section and each drive section.

[0065] The main advantage of this setup is that, by ensuring a one-to-one correspondence between each roller pressing section and each drive section, uniform pressure and drive can be achieved for the electrode strip 6 or the finished electrode sheet throughout the entire conveying process, significantly improving processing accuracy and consistency. Furthermore, designing the clearance groove 102 as multiple spaced-apart grooves 1021 allows the guide section 101 to partially support the electrode strip 6 or the finished electrode sheet between adjacent grooves 1021. This ensures continuous support for the electrode strip 6 or the finished electrode sheet during conveying, preventing sagging or sinking into the grooves 1021, thus avoiding the risk of the electrode strip 6 falling off and improving conveying reliability.

[0066] In this embodiment, as a preferred implementation, multiple roller conveying components 2 are arranged at intervals along a preset direction, and multiple clearance grooves 102 are arranged corresponding to each roller conveying component 2. This ensures that the electrode strip 6 or the cut electrode sheet remains on the predetermined path during transport, reducing feeding errors caused by positional deviations.

[0067] Example 2

[0068] This embodiment relates to a cutting device, which includes the electrode feeding mechanism described in Embodiment 1. The electrode feeding mechanism smoothly conveys the electrode strip 6, helping to reduce cutting errors and ensuring that each cut electrode has a consistent size and shape, thus improving the quality of the finished electrode product.

[0069] Furthermore, in this embodiment, as a preferred implementation, such as Figure 1 As shown, the cutting device also includes a cutting assembly 5 disposed between two adjacent roller feeding assemblies 2, the cutting assembly 5 having a cutting unit 501 for cutting the electrode strip 6.

[0070] Specifically, the guide section 101 may also be provided with a drop groove corresponding to the cutting unit 501, ensuring that the cutting unit 501 can completely penetrate the electrode strip 6 without any obstruction, thereby improving the cutting accuracy and consistency. The roller conveying assembly 2 located upstream of the cutting unit 501 along a preset direction is used to convey the electrode strip 6 to the cutting assembly 5. After the cutting unit 501 cuts the electrode strip 6, the roller conveying assembly 2 located downstream of the cutting unit 501 will continue to convey the cut electrode sheet, preventing the electrode sheet from being blocked in the cutting device. The cutting assembly 5 and the two roller conveying assemblies 2 before and after form a seamless connection, enabling feeding, cutting and subsequent processes to work together efficiently, reducing unnecessary downtime and adjustment time, and improving the overall operating efficiency of the production line.

[0071] Furthermore, in this embodiment, as a preferred implementation, such as Figure 1 As shown, the cutting device also includes a worktable 4. The cutting assembly 5 is mounted on the worktable 4 via a second base 402, and the cutting unit 501 is slidably mounted on the second base 402. The second base 402 provides reliable support for the cutting assembly 5, ensuring that the cutting unit 501 remains stable during the cutting process. It should be noted that the worktable 4 in the cutting device is the same as the worktable 4 of the electrode feeding mechanism. The second base 402 is inverted U-shaped and has a crossbeam and support beams at both ends of the crossbeam. The two support beams are connected to the upper surface of the worktable 4, and the cutting unit 501 is slidably mounted below the crossbeam.

[0072] Furthermore, in this embodiment, as a preferred implementation, such as Figure 1As shown, the second base 402 is provided with guide holes 4021 arranged in the vertical direction, and the cutting unit 501 is provided with guide members 5011. The guide members 5011 are slidably disposed in the guide holes 4021. The design of the guide holes 4021 and the guide members 5011 ensures that the cutting unit 501 can make precise vertical movements along a predetermined path when moving up and down. This helps to maintain the stability of the cutting unit 501 throughout the cutting process, reduces the cutting error of the electrode sheet due to offset or tilt of the cutting unit 501, and improves cutting reliability and consistency. Specifically, a linear bearing can be arranged in the guide holes 4021, and the guide member 5011 is a guide rod. The guide rod is slidably disposed in the linear bearing, which can greatly reduce the guiding friction of the guide rod, so that the cutting unit 501 can move up and down more smoothly and improve the cutting accuracy of the electrode strip 6.

[0073] Preferably, the cutting assembly 5 includes a third drive unit, the drive end of which is driven and connected to the cutting unit 501. The third drive unit drives the cutting unit 501 to move up and down. During the downward movement of the cutting unit 501, the electrode strip 6 is cut; conversely, during the upward movement of the cutting unit 501, the electrode strip 6 is propelled by the electrode feeding mechanism. Specifically, the cutting unit 501 is equipped with a connecting rod, and the drive end of the third drive unit is connected to the connecting rod. The third drive unit can be any one of the following: a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, similar to the second drive unit 302; further details will not be provided here. Furthermore, the third drive unit can be mounted on the second base 402, directly on the worktable 4, or separately on other mounting bases such as a frame.

[0074] In addition, in this embodiment, as a preferred implementation, such as Figure 1 As shown, the cutting components 5 are multiple sets arranged at intervals along a preset direction. By having multiple sets of cutting components 5 work together, the electrode strip 6 can be cut into multiple electrode sheets at the same time, increasing the output per unit time and improving the overall production efficiency.

[0075] Specifically, the cutting assembly 5 can be in two sets, namely a first cutting assembly and a second cutting assembly; the roller conveying assembly 2 can be in three sets, namely a first roller conveying assembly, a second roller conveying assembly, and a third roller conveying assembly arranged at intervals along a preset direction; wherein, the first cutting assembly is located between the first roller conveying assembly and the second roller conveying assembly, and the second cutting assembly is located between the second roller conveying assembly and the third roller conveying assembly. The first roller conveying assembly conveys the electrode strip 6 along the preset direction so that the first and second cutting assemblies can cut the electrode strip 6 into electrode sheets. After the electrode strip 6 is cut, the second and third roller conveying assemblies convey the cut electrode sheets along the preset direction.

[0076] Of course, the number of roller conveying components 2 can be increased according to actual production needs. At this time, it should be noted that the number of cutting components 5 should also be increased accordingly, but preferably one less than that of roller conveying components 2, in order to achieve more efficient cutting. In addition, all structures not mentioned in the cutting device of this embodiment can refer to the structures in common electrode cutting equipment in the prior art, and will not be described in detail here.

[0077] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
