Description

Technical Field

[0001] This utility model relates to the field of lithium battery electrode technology, specifically to a coating and drying integrated machine. Background Technology

[0002] The coating machine is a core piece of equipment in the front-end process of lithium-ion battery manufacturing. It is mainly used to uniformly coat the active material slurry onto the surface of the metal current collector (copper foil / aluminum foil) to form an electrode coating. The coating machine conveys the foil substrate through the unwinding device, transfers the slurry to the substrate surface through the coating head, and then dries and rewinds to complete the initial forming of the electrode sheet.

[0003] To improve the energy density of batteries, active material slurry needs to be coated on both sides of the electrode. After coating one side of the electrode, it needs to be placed in a drying oven for drying. Therefore, two drying ovens and two coating mechanisms are required. In order to ensure that the solvent of the active material slurry is fully evaporated, the length of the drying oven is usually 15-30 meters. This results in the long total length of the existing double-sided coating production line, which needs to be set up in a factory with a large floor area, thus increasing the factory floor area cost. Currently, there are also mechanisms that stack two drying boxes to save floor space. These mechanisms use two-tiered support frames, with one drying box placed on the higher support frame. However, during the coating process, the distance between the coating die sliders is only about 1 cm. Workers need to observe the thickness gauge data in real time at the coating mechanism and manually adjust the slider distance to ensure coating uniformity. To facilitate worker operation, both coating mechanisms are located on the factory floor. This results in the electrode having to climb up a slope with the wet slurry just coated on its surface to the drying box on the higher support frame for drying after the second coating is completed. During the climbing process, the wet slurry may flow back and shake, which seriously affects the coating quality of the product. Utility Model Content

The machine includes a first drying oven assembly and a second drying oven assembly, which are respectively located on the lower frame and the upper frame. The first drying oven assembly is located between the unwinding assembly and the first traction assembly, and the second drying oven assembly is located between the rising traction assembly and the second traction assembly. The coating mechanism includes a first coating assembly and a second coating assembly. The first coating assembly is located on the upper frame and between the unwinding assembly and the first drying oven assembly, and the second coating assembly is located between the rising traction assembly and the second drying oven assembly. The elevator mechanism spans across the upper frame and the lower frame.

[0006] Preferably, the coating and drying integrated machine further includes a slitting mechanism, and the material transfer mechanism further includes a third traction component. The third traction component and the slitting mechanism are respectively located on the lower frame, and the unwinding component, the first traction component, the rising traction component, the second traction component, the third traction component, the slitting mechanism and the winding component are arranged sequentially along the direction of material movement.

[0007] Preferably, the slitting mechanism includes a slitting frame assembly and a slitting component disposed on the slitting frame assembly. The slitting frame assembly is disposed on the lower frame and is located between the third traction assembly and the winding assembly.

[0008] Preferably, the lifting traction assembly includes a lifting frame, a guide roller drive, and multiple guide rollers. The lifting frame spans the upper frame and the lower frame. The multiple guide rollers are arranged sequentially and rotatably within the lifting frame along the vertical direction. The guide roller drive is connected to the multiple guide rollers respectively.

[0009] Preferably, the guide roller drive includes a guide roller drive body, a drive wheel, and a drive belt. The drive end of the guide roller drive body is connected to the drive wheel, and the drive belt is sequentially wound around the drive wheel and multiple guide roller components.

[0010] Preferably, the guide roller drive also includes a tensioning track and a tensioning wheel. The tensioning track is located on the lifting frame, and the tensioning wheel is movably located on the tensioning track. Adjusting the position of the tensioning wheel on the tensioning track allows the tensioning wheel to loosen or tighten the drive belt.

[0011] Preferably, the material transfer mechanism further includes a first web guiding component, which is located on the lower frame and between the unwinding component and the first coating component.

[0012] Preferably, the material transfer mechanism further includes a second correction component, which is disposed on the upper frame and located between the lifting traction component and the second coating component.

[0014] Preferably, the testing mechanism includes a first density testing component and a second density testing component, wherein the first density testing component is disposed between the first coating component and the first oven component, and the second density testing component is disposed between the second coating component and the second oven component.

[0015] The beneficial effects of this application are as follows: The coating and drying integrated machine of this application can realize fully automatic unwinding, double-sided coating, drying and rewinding of foil materials in one unit. At the same time, since the upper frame is set above the lower frame and the second drying oven assembly is set on the upper frame, that is, the second drying oven assembly is located above the first drying oven assembly, it can realize double-sided coating and drying without occupying a large amount of additional factory floor space.

[0016] Furthermore, since the second coating assembly is located on the upper frame, after the second coating assembly coats the other side of the foil, it can directly enter the second drying oven assembly, which is also located on the upper frame, for drying. There is no need for upward and inclined conveying, which effectively reduces the backflow and shaking of undried slurry on the foil surface during upward and inclined conveying, greatly reducing the quality risks of wrinkling and affecting the coating density, and improving the yield rate.

[0017] Furthermore, the lifting mechanism allows operators to ascend to the upper frame and operate the second coating assembly located on the upper frame for coating operations. This means that the electrode sheets coated by the second coating assembly can directly enter the second drying oven assembly, which is also located on the upper frame, for drying without having to climb a slope.

[0018] Furthermore, by setting up a slitting mechanism, wider foils can be selected for coating operations, improving coating production efficiency. After coating, the electrode sheets are wound up before being wound into the winding assembly. The slitting mechanism first cuts the electrode sheets and then winds them up separately. Since the width of the cut electrode sheets is halved, wide-width equipment is not needed in the subsequent rolling process, which reduces the actual width of the equipment used in the later process, improves the electrode sheet pressing accuracy, effectively reduces the wrinkling of the electrode sheet, and ensures that the electrode sheets are flat after slitting, making it easy to cut with laser without producing burrs.

[0024] To further understand the content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0025] Reference Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the coating and drying integrated machine in the embodiment. Figure 2 The diagram below illustrates the structure of the lifting mechanism in this embodiment. The coating and drying integrated machine includes a frame 1, a material transfer mechanism 2, a drying mechanism 3, a coating mechanism 4, and a lifting mechanism 5. The frame 1 includes an upper frame 11 and a lower frame 12, with the upper frame 11 mounted above the lower frame 12. The material transfer mechanism 2 includes an unwinding assembly 21, a first traction assembly 22, a rising traction assembly 23, a second traction assembly 24, and a winding assembly 25 arranged sequentially along the roll movement direction. The unwinding assembly 21 and the first traction assembly 22 are respectively located on the lower frame 12, the rising traction assembly 23 spans across the upper frame 11 and the lower frame 12, the second traction assembly 24 is located on the upper frame 11, and the winding assembly 25 is located on the lower frame 12. The drying mechanism 3 includes a first drying oven assembly 31 and a second drying oven assembly 32, which are respectively located on the lower frame 12 and the upper frame 11. The first drying oven assembly 31 is situated between the unwinding assembly 21 and the first traction assembly 22, and the second drying oven assembly 32 is situated between the rising traction assembly 23 and the second traction assembly 24. The coating mechanism 4 includes a first coating assembly 41 and a second coating assembly 42, which are located on the upper frame 11 and between the unwinding assembly 21 and the first drying oven assembly 31. The second coating assembly 42 is situated between the rising traction assembly 23 and the second drying oven assembly 32. The lifting mechanism 5 spans across the upper frame 11 and the lower frame 12.

[0026] The coating and drying integrated machine in this embodiment is placed on the factory floor and is used for unwinding, coating, drying, and rewinding of electrode sheets. In specific application, the unwinding assembly 21 is used to unwind the foil. The foil is traction-conveyed by the first traction assembly 22 and sequentially passes through the first coating assembly 41 and the first drying oven assembly 31. The first coating assembly 41 coats one side of the foil. After coating, the foil enters the first drying oven assembly 31 for drying. After drying, the foil is traction-conveyed by the rising traction assembly 23 to the upper frame 11 and flipped. The second coating assembly 42 coats the other side of the foil. After coating, the foil is traction-conveyed by the second traction assembly 24 into the second drying oven assembly 32 for drying, and finally rewinding to the rewinding assembly 25. Thus, the coating and drying integrated machine in this embodiment can achieve fully automatic unwinding, double-sided coating, drying, and rewinding of foil in one integrated process. Meanwhile, since the upper frame 11 is mounted above the lower frame 12, and the second drying oven assembly 32 is located on the upper frame 11 (i.e., above the first drying oven assembly 31), double-sided coating and drying can be achieved without requiring a large additional factory floor space. Furthermore, because the second coating assembly 42 is located on the upper frame 11, after coating the other side of the foil, it can directly enter the second drying oven assembly 32, also located on the upper frame 11, for drying, without the need for upward and inclined conveying. This effectively reduces the risk of backflow and shaking of undried slurry on the foil surface during upward and inclined conveying, greatly reducing the quality risks of wrinkling and affecting coating density, and improving the yield rate. The lifting mechanism 5 allows operators to easily ascend to the upper frame 11 and operate the second coating assembly 42 located on the upper frame 11 for coating operations. This allows the second coating assembly 42 to be positioned on the upper frame 11, meaning that the electrode sheets coated by the second coating assembly 42 can directly enter the second drying oven assembly 32, also located on the upper frame 11, for drying without needing to climb an incline. Specifically, both the upper frame 11 and the lower frame 12 are constructed from high-strength, stable reinforced concrete independent support platforms to ensure structural and operational stability. Operators can walk on the upper frame 11. The lifting mechanism 5 is a personnel-carrying lifting elevator.

[0027] Reference Figure 3 , Figure 3The diagram illustrates the structure of the slitting mechanism in this embodiment. Preferably, the integrated fabric drying machine further includes a slitting mechanism 6, and the material transfer mechanism 2 includes a third traction component 26. The third traction component 26 and the slitting mechanism 6 are respectively located on the lower frame 12, and the unwinding component 21, the first traction component 22, the rising traction component 23, the second traction component 24, the third traction component 26, the slitting mechanism 6, and the winding component 25 are arranged sequentially along the direction of material movement. With the slitting mechanism 6, a wider foil material can be selected for coating operations, improving coating production efficiency. Simultaneously, after coating, before winding it up to the winding component 25, the slitting mechanism 6 first slits the electrode sheets and then winds them up separately. Because the width of the slit electrode sheets is halved, wide-width equipment is not needed in subsequent rolling processes, reducing the actual width of the equipment used in later processes, improving the electrode sheet pressing accuracy, effectively reducing electrode sheet wrinkling, ensuring the electrode sheets are flat after slitting, facilitating laser cutting without burrs. Specifically, in this embodiment, the unwinding assembly 21 is a shaft-type unwinding mechanism. The winding assembly 25 is also a shaft-type unwinding mechanism, and the winding assembly 25 has two winding rollers for respectively winding the two slit electrode sheets.

[0028] Rereference Figure 3 Preferably, the slitting mechanism 6 includes a slitting frame assembly 61 and a slitting component 62 disposed on the slitting frame assembly 61. The slitting frame assembly 61 is located on the lower frame 12 and is situated between the third traction assembly 26 and the winding assembly 25. In specific applications, the slitting frame assembly 61 is a slitting frame, and the slitting component 62 is a circular blade slitting mechanism disposed on the slitting frame assembly 61. It is used to pre-slit the electrode sheet before winding, dividing the wide electrode sheet into two parts by the slitting blade, and then winding the electrode sheet in two stages onto the winding assembly 25. Specifically, the first traction assembly 22, the second traction assembly 24, and the third traction assembly 26 are all roll traction mechanisms.

[0029] Reference Figure 4 , Figure 4The above is a schematic diagram of the structure of the lifting traction assembly in the embodiment. Preferably, the lifting traction assembly 23 includes a lifting frame 231, a guide roller drive 232 and a plurality of guide rollers 233. The lifting frame 231 spans the upper frame 11 and the lower frame 12. The plurality of guide rollers 233 are arranged in the lifting frame 231 at intervals and rotatably along the vertical direction. The guide roller drive 232 is connected to the plurality of guide rollers 233 respectively. In practical applications, the lifting frame 231 serves as the lifting frame, and the guide roller 233 includes guide rollers 2331 and pulleys 2332. Multiple guide rollers 2331 are arranged vertically at intervals and rotatably within the lifting frame 231. One end of each guide roller 233 is fitted with a pulley 2332. The guide roller drive 232 includes a guide roller drive body, a drive wheel 2321, and a drive belt 2322. The drive end of the guide roller drive body is connected to the drive wheel 2321, and the drive belt 2322 is sequentially wound around the drive wheel 2321 and the multiple guide rollers 233. This drives the motor. Drive wheel 2321 rotates, which in turn drives drive belt 2322. Drive belt 2322 then drives multiple pulleys 2332, which in turn drives multiple guide rollers 2331. Essentially, as the electrode sheet passes over the guide rollers 2331, it rises in a reciprocating left-right oscillation. The guide rollers 2331 guide the electrode sheet sequentially, and the second traction assembly 24 pulls the electrode sheet from the lower frame 12 to the upper frame 11, simultaneously flipping it so that the uncoated side faces upwards. Specifically, the guide roller drive is a drive motor.

[0030] Rereference Figure 4 Preferably, the guide roller drive component 232 further includes a tensioning rail 2323 and a tensioning wheel 2324. The tensioning rail 2323 is located on the lifting frame component 231, and the tensioning wheel 2324 is movably located on the tensioning rail 2323. Adjusting the position of the tensioning wheel 2324 on the tensioning rail 2323 allows the tensioning wheel 2324 to loosen or tighten the drive belt 2322. Through the arrangement of the tensioning rail 2323 and the tensioning wheel 2324, the tension of the drive belt 2322 can be adjusted, ensuring that the drive belt 2322 can provide sufficient traction to drive the multiple pulleys 2332 to rotate. Furthermore, the multiple pulleys 2332 are all connected in series by belts and driven by a single guide roller drive component, ensuring synchronous rotation. Specifically, the tensioning wheel 2324 includes a movable block and a rotating wheel. The movable block is slidably disposed on the tensioning track 2323 and can be fixed to the lifting frame body 231 by screws. The rotating wheel is rotatably sleeved outside the movable block and abuts against the drive belt 2322.

[0031] Rereference Figure 1Preferably, the material transfer mechanism 2 further includes a first correction component 27, which is located on the lower frame 12 and between the unwinding component 21 and the first coating component 41. Before the electrode is coated at the first coating component 41, the first correction component 27 corrects the position of the electrode, ensuring that the first coating component 41 can accurately coat the slurry onto the electrode, thus improving the coating quality of the product. Furthermore, the material transfer mechanism 2 also includes a second correction component 28, which is located on the upper frame 11 and between the lifting traction component 23 and the second coating component 42. The second correction component 28 corrects the position of the electrode before the electrode is coated at the second coating component 42, ensuring that the second coating component 42 can accurately coat the slurry onto the electrode, thus improving the coating quality of the product. Specifically, both the first correction assembly 27 and the second correction assembly 28 are electrode correction mechanisms. The first coating assembly 41 and the second coating assembly 42 are slurry coating mechanisms.

[0032] Rereference Figure 1 Preferably, the coating and drying integrated machine further includes a detection mechanism 7, which is located on the upper frame 11 and between the second traction assembly 24 and the winding assembly 25. In specific applications, the detection mechanism 7 includes a first density detection component 71 and a second density detection component 72. The first density detection component 71 is located between the first coating assembly 41 and the first drying oven assembly 31, and the second density detection component 72 is located between the second coating assembly 42 and the second drying oven assembly 32. Through the setting of the first density detection component 71 and the second density detection component 72, the coating surface density of the electrode sheet is monitored in real time after coating. The operator can adjust the slurry coating mechanism based on the data detected by the first density detection component 71 and the second density detection component 72 to ensure coating uniformity and improve battery capacity, safety, and consistency. Specifically, both the first density detection component 71 and the second density detection component 72 are laser thickness and surface density detection mechanisms, with their detection ends facing the electrode sheet surface.

[0033] In summary, the coating and drying integrated machine in this embodiment can achieve fully automatic unwinding, double-sided coating, drying, and rewinding of foil materials in one integrated manner. Furthermore, since the upper frame 11 is mounted above the lower frame 12, and the second drying oven assembly 32 is located on the upper frame 11 (i.e., above the first drying oven assembly 31), double-sided coating and drying can be achieved without requiring a large additional factory floor space. Moreover, because the second coating assembly 42 is located on the upper frame 11, after coating the other side of the foil, it can directly enter the second drying oven assembly 32, also located on the upper frame 11, for drying, without the need for upward and inclined conveying. This effectively reduces the risk of backflow and shaking of undried slurry on the foil surface during upward and inclined conveying, greatly reducing the quality risks of wrinkling and affecting coating density, and improving the yield rate. Furthermore, the lifting mechanism 5 allows operators to easily ascend to the upper frame 11, facilitating the operation of the second coating assembly 42 located on the upper frame 11. This allows the second coating assembly 42 to be positioned on the upper frame 11, meaning the coated electrode sheets can directly enter the second drying oven assembly 32, also located on the upper frame 11, for drying without needing to climb an incline. Additionally, the slitting mechanism 6 allows for the use of wider foil materials during coating, improving production efficiency. After coating, before winding up to the winding assembly 25, the slitting mechanism 6 first slits the electrode sheets and then winds them up separately. Because the width of the slit electrode sheets is halved, wider equipment is not needed in subsequent rolling processes, reducing the actual width of equipment used in later processes, improving electrode pressing accuracy, effectively reducing wrinkling during pressing, ensuring the electrode sheets are flat after slitting, and facilitating laser cutting without burrs.
