Description

Technical Field

[0001] This application relates to the field of drying equipment technology, and more specifically, to a nozzle device, an oven device, and a battery production system. Background Technology

[0002] In the battery manufacturing process, a slurry is applied to the surface of a substrate, which is then baked in an oven to form an electrode. During the baking process, the areas on the substrate without slurry coating are lighter and thinner, making them easier to dry than the areas with slurry coating. This causes stress deformation and cracking of the film during the heat shrinkage process, directly affecting the forming quality of the electrode. Utility Model Content

[0003] In view of the above problems, this application provides a nozzle device, an oven equipment, and a battery production system, which helps to improve the forming quality of electrode sheets.

[0004] In a first aspect, this application provides a nozzle device, comprising: a nozzle body including a first wall having a plurality of air outlets; a blocking member disposed along the thickness direction of the first wall on a side of the first wall opposite to the interior of the nozzle body; and a drive assembly disposed on the nozzle body, the drive assembly including a drive member and a guide member, the blocking member being connected to the guide member, the drive member being configured to drive the guide member to move relative to the first wall along the length direction of the first wall, so that the blocking member can block a portion of the air outlets.

[0005] In some embodiments of the first aspect, the position of the shielding member is adjusted by the driving member so that the shielding member can block the air outlet opposite to the area on the substrate that is not coated with slurry, thereby blocking the airflow blown out from this part of the air outlet, reducing the drying rate of the area on the substrate that is not coated with slurry, thereby improving the problem of easy cracking in this part of the area and improving the forming quality of the electrode sheet.

[0006] In some embodiments, the guide includes a slidingly connected guide rail and a slider, the guide rail being connected to the nozzle body and extending along the length direction, and the shielding member being connected to the slider.

[0007] The above technical solution is beneficial to improving the stability of the movement of the shielding component through the guide component.

[0008] In some embodiments, the nozzle device further includes a control component electrically connected to the drive component. This configuration facilitates the automated design of the nozzle device.

[0009] In some embodiments, there are multiple guide members and multiple blocking members, with each guide member and blocking member corresponding to the other, and the multiple blocking members are arranged along the length direction.

[0010] In the above technical solution, each shielding component moves relative to the first wall along the length direction through an independent guide, which helps to improve the stability of the movement of each shielding component, thereby improving the reliability of the nozzle device.

[0011] In some embodiments, there are multiple driving elements, and the driving elements and guide elements are arranged in a one-to-one correspondence.

[0012] The above technical solution is beneficial to improving the accuracy of the drive component in driving the guide component, so that the blocking component moves through the guide component, and also helps to reduce the failure rate.

[0013] In some embodiments, the drive assembly further includes a housing and a connecting wire. The housing is connected to the nozzle body, and the connecting wire is disposed within the housing. The drive component and the guide component are electrically connected via the connecting wire. This configuration helps to improve the reliability and stability of the nozzle device.

[0014] In some embodiments, the nozzle body further includes a second wall that intersects with the first wall, and the second wall is connected to either side of the first wall along its width direction, and at least one second wall is connected to a drive component.

[0015] In the above technical solution, the drive component is connected to the second wall, which is reasonable in layout and easy to assemble.

[0016] In some embodiments, the shielding member is a plate-like structure arranged parallel to the first wall, and the distance between the shielding member and the first wall in the thickness direction is greater than or equal to 3 mm and less than or equal to 7 mm. This arrangement helps to improve the reliability of the nozzle device and also helps to reduce the possibility of cracking in areas of the substrate where no slurry is applied.

[0017] In some embodiments, the distance between the shield and the first wall is greater than or equal to 4 mm and less than or equal to 6 mm. This arrangement further improves the reliability of the nozzle device and reduces the likelihood of cracking in areas of the substrate not coated with the slurry.

[0018] In some embodiments, in the length direction, at least two of the plurality of air outlets are spaced apart, and the size of any one of the air outlets is smaller than the size of the shield; and / or, in the width direction of the first wall, at least two of the plurality of air outlets are spaced apart, and the shield protrudes from the air outlet on either side along the width direction.

[0019] In the above technical solution, it can be ensured that the shielding component can completely block the air outlet. Specifically, the position of the shielding component can be adjusted by the driving component to set the size of the area that it can block the air outlet, which is beneficial to improving the flexibility of the use of the nozzle device.

[0020] Secondly, this application provides an oven device, including: a chamber; and a nozzle device provided according to any embodiment of the first aspect, the nozzle device being disposed within the chamber.

[0042] In this application, "multiple" means two or more (including two).

[0043] Currently, judging from market trends, the application of batteries is becoming increasingly widespread. Batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also widely applied in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of battery application areas, the market demand for batteries is also constantly increasing.

[0044] In the battery manufacturing process, a slurry is applied to the surface of a substrate, which is then baked in an oven to form an electrode. During baking, the areas of the substrate without slurry coating are lighter and thinner, making them easier to dry than the areas with slurry coating. This results in the slurry-coated areas drying more slowly than the uncoated areas. The uncoated areas shrink inwards when heated, causing them to separate from the slurry-coated areas, directly affecting the electrode forming quality.

[0045] Based on the above-mentioned technical problems, this application provides a nozzle device, including a nozzle body, a shielding member, and a driving component. The position of the shielding member can be adjusted by the driving component so that the shielding member can block the air outlet opposite to the area on the substrate that is not coated with slurry, thereby blocking the airflow blown out from this part of the air outlet, reducing the drying rate of the area on the substrate that is not coated with slurry, thereby improving the cracking problem in this part of the area and improving the forming quality of the electrode sheet.

[0046] The nozzle device provided in this application embodiment can be provided separately, can be manufactured and sold as an independent component, and can also be used as a component of oven equipment.

[0047] Please refer to the following: Figures 1 to 3According to an embodiment of this application, a nozzle device 1 is provided, including a nozzle body 10, a blocking member 20, and a drive assembly 30. The nozzle body 10 includes a first wall 11, which has a plurality of air outlets 111. Along the thickness direction X of the first wall 11, the blocking member 20 is disposed on the side of the first wall 11 opposite to the interior of the nozzle body 10. The drive assembly 30 is disposed on the nozzle body 10 and includes a drive member 31 and a guide member 32. The blocking member 20 is connected to the guide member 32. The drive member 31 is configured to drive the guide member 32 to move relative to the first wall 11 along the length direction Y of the first wall 11, so that the blocking member 20 can block a portion of the air outlets 111.

[0048] In this context, the thickness direction X of the first wall 11 can be understood as the height direction of the nozzle body 10, the length direction Y of the first wall 11 can be understood as the length direction of the nozzle body 10, and the width direction Z of the first wall 11 can be understood as the width direction of the nozzle body 10.

[0049] Understandably, an electrode consists of a main body and a tab. Before forming the electrode, a slurry needs to be coated onto a substrate. The coated substrate can be called a film. After drying, the film can be cut into multiple electrodes. The area on the film coated with slurry can be called the coating area, corresponding to the main body of the electrode. The area on the film not coated with slurry can be called the blank area, corresponding to the tab of the electrode.

[0050] Some membranes may have a coating area, a blank area, and another coating area sequentially along their width direction; others may have a coating area, a blank area, a coating area, and so on, with a blank area and a coating area. The coating area and the blank area extend along the length direction of the membrane. It can be understood that the width direction of the membrane is parallel to the length direction Y of the first wall 11, and the length direction of the membrane is parallel to the width direction Z of the first wall 11.

[0051] Depend on Figure 1 As shown, during the actual use of the nozzle device 1, the diaphragm moves along its own length direction, that is, the diaphragm passes through the nozzle device 1 from one side of the width direction Z of the first wall 11, and the shielding member 20 is located between the first wall 11 and the diaphragm. The shielding member is used to shield the air outlet 111 corresponding to the blank area of ​​the diaphragm in the thickness direction X.

[0052] Depend on Figure 4As shown, the nozzle device 1 can be installed inside the oven body 2 to dry the film entering the oven body 2. The film can enter the oven body 2 through the inlet 21 for drying. The nozzle devices 1 located on the upper and lower sides of the oven body 2 blow air into the oven body 2 through the air outlet 111. Specifically, the shielding member 20 can be moved to the position of the air outlet 111 opposite to the blank area of ​​the film to block this part of the air outlet 111, slowing down the drying rate of the blank area, so that the drying time of the blank area and the coating area tends to be consistent, thereby helping to improve the cracking problem of the blank area of ​​the film during the drying process.

[0053] Therefore, the nozzle device 1 provided in some embodiments of this application can adjust the position of the blocking member 20 by the driving member 31 so that the blocking member 20 can block the air outlet 111 opposite to the blank area of ​​the film, thereby blocking the airflow blown out from the air outlet 111, reducing the drying rate of the film in the blank area, thereby improving the problem of cracking in the blank area and improving the quality of the battery cell.

[0054] In this embodiment of the application, the nozzle body 10 refers to a component that can provide an installation position for other components in the nozzle device 1, and can also enclose a cavity for airflow.

[0055] For example, the nozzle body 10 can be configured as a cylindrical structure, that is, the first wall 11 can be the side wall of the nozzle body 10 with a cylindrical structure. The first wall 11 has multiple air outlets 111, and the first wall 11 is also provided with multiple air inlets on the side facing away from the air outlets 111 in the radial direction. The airflow can enter the interior of the nozzle body 10 through the air inlets and be discharged through the air outlets 111 to dry the diaphragm.

[0056] For example, the nozzle body 10 can be configured as a rectangular structure, that is, the first wall 11 can be one of the walls of the rectangular nozzle body 10. The first wall 11 has multiple air outlets 111, and the walls spaced apart from the first wall 11 also have multiple air inlets.

[0057] Optionally, the shape of the air outlet 111 may include, but is not limited to, a circle, an ellipse, or a polygon.

[0058] The shielding component 20 is used to block a portion of the air outlets 111. The shielding component 20 can be used to block the air outlets 111 opposite to the blank area, and it can also be used to block the air outlets 111 opposite to the painted area. The specific settings can be configured according to actual needs.

[0059] Optionally, the shield 20 can be configured as a fully enclosed structure, that is, the airflow blown from the air outlet 111 onto the shield 20 will not pass through the shield 20, but will instead blow around the periphery of the shield 20.

[0060] Alternatively, the shield 20 can also be configured to have a perforated structure, that is, the airflow blown from the air outlet 111 onto the shield 20 can flow through the perforations on the shield 20.

[0061] like Figure 1 As shown, in some embodiments, the drive component 30 can be connected to the nozzle body 10, which helps to avoid occupying external space and thus improves the structural compactness of the nozzle device 1.

[0062] like Figure 3 and Figure 4 As shown, in other embodiments, the drive assembly 30 may also be fixed to an external component and connected to the shield 20 by means of the guide 32. For example, the drive assembly 30 may be connected to the housing 2 of the baking equipment.

[0063] The driving component 31 is used to drive the guide component 32 to move relative to the first wall 11 along the length direction Y, so as to drive the shielding component 20 of the guide component 32 to move along the length direction Y. Specifically, the position of the shielding component 20 can be adjusted according to the distribution of the blank area and the paint area on the diaphragm and the actual needs.

[0064] By setting it up in the above manner, there is no need to manually adjust the position of the shield 20, which helps to reduce the difficulty of the operator's work and improves the accuracy and efficiency of the nozzle device 1.

[0065] Optionally, the shield 20 can block the entire air outlet 111 or block only part of the air outlet 111.

[0066] Optionally, the drive unit 31 may be configured as including but not limited to a micro motor, cylinder, etc.

[0067] Optionally, the guide member 32 can be configured as a slidingly connected guide rail and slider structure, or as a telescopic rod structure that can be extended or retracted.

[0068] like Figure 2 As shown, in some optional embodiments, the guide 32 includes a slidingly connected guide rail 321 and a slider 322. The guide rail 321 is connected to the nozzle body 10 and extends along the length direction Y, and the shield 20 is connected to the slider 322.

[0069] The above-mentioned configuration helps to improve the stability and accuracy of the movement of the blocking component 20 along the length direction Y.

[0070] In some alternative embodiments, the nozzle device 1 further includes a control component electrically connected to the drive element 31.

[0071] The control component can drive the drive component 31 via electrical signals to precisely adjust the position of the shielding component 20 to adapt to different types of diaphragms, which helps to improve the flexibility of the nozzle device 1.

[0072] After receiving the instruction from the control component, the drive component 31 drives the guide component 32 to move relative to the first wall 11 along the length direction Y, thereby driving the blocking component 20 to move, so as to adjust the position of the blocking component 20.

[0073] Optionally, the drive unit 31 may have a built-in sensor or encoder to feed back the position of the blocking member 20 to the control component, which can provide real-time feedback on the position of the blocking member 20 and improve the accuracy of driving the movement of the blocking member 20.

[0074] The nozzle device 1 provided in some embodiments of this application has a control component that can drive the drive component 31 in the form of an electrical signal to adjust the position of the shielding component 20. This is beneficial for improving the automation design, thereby improving the accuracy and efficiency of adjusting the position of the shielding component 20. Furthermore, it is also possible to adjust the position of the shielding component 20 in real time according to the surface information of the dried film under the operating conditions of the nozzle device 1, thereby improving the forming quality of the electrode sheet.

[0075] Please continue reading Figure 1 In some optional embodiments, there are multiple guide members 32 and multiple blocking members 20. The guide members 32 and the blocking members 20 are arranged in a one-to-one correspondence, and the multiple blocking members 20 are arranged along the length direction Y.

[0076] Each shielding component 20 is connected to a corresponding guide component 32. Each shielding component 20 moves relative to the first wall 11 along the length direction Y via an independent guide component 32, which helps to improve the stability of the movement of each shielding component 20, thereby improving the reliability of the nozzle device 1.

[0077] Multiple blocking elements 20 can be arranged at equal intervals along the length direction Y. Of course, they can also be arranged at non-equal intervals.

[0078] In some embodiments, a plurality of guide members 32 are arranged along the length direction Y. This arrangement avoids interference between the various blocking members 20 during movement, thereby improving the reliability of the nozzle device 1.

[0079] In some alternative embodiments, there are multiple driving elements 31, and the driving elements 31 and the guide elements 32 are arranged in a one-to-one correspondence.

[0080] Each guide 32 is controlled by an independent drive 31, which helps to improve the accuracy of the drive 31 in driving the guide 32 so that the obstruction 20 moves through the guide 32, and also helps to reduce the failure rate.

[0081] Optionally, there may be multiple drive components 31, and each drive component 31 and slider 322 may be electrically connected in a one-to-one correspondence.

[0082] like Figure 1 As shown, in some optional embodiments, the drive assembly 30 further includes a housing 33 and a connecting wire. The housing 33 is connected to the nozzle body 10, and the connecting wire is disposed inside the housing 33. The drive component 31 and the guide component 32 are electrically connected through the connecting wire.

[0083] The housing 33 is used to protect the connecting wires to prevent them from being directly exposed to the external environment and causing damage or interference with other components, which helps to improve the reliability of the nozzle device 1.

[0084] The connecting line is used to realize signal transmission between the drive component 31 and the guide component 32. The drive component 31 sends control commands to the guide component 32 through the connecting line to drive the guide component 32 to perform linear motion, which helps to improve the stability of the nozzle device 1.

[0085] Optionally, the housing 33 can be detachably connected to the nozzle body 10 using fasteners such as bolts and screws, which facilitates maintenance of the nozzle device 1. Optionally, the housing 33 can also be connected to the nozzle body 10 via a snap-fit ​​connection.

[0086] Optionally, the housing 33 can also be fixedly connected to the nozzle body 10 by welding.

[0087] Optionally, the box 33 may be provided with a cable routing channel, or the space inside the box 33 may be divided into multiple sub-cavities to ensure the orderly arrangement of the connecting wires and prevent them from getting tangled or squeezed, which could lead to safety risks.

[0088] Optionally, when the drive element 31 is set as the first, one drive element 31 is electrically connected to each guide element 32 through multiple connecting lines, and the guide element 32 is set in a one-to-one correspondence with the connecting lines.

[0089] Optionally, when multiple drive components 31 are configured, each drive component 31 and each guide component 32 are electrically connected by an independent connecting line, and the drive component 31, guide component 32 and connecting line are configured in a one-to-one correspondence.

[0090] Please see Figure 1 and Figure 2In some optional embodiments, the nozzle body 10 further includes a second wall 12 that intersects with the first wall 11. The first wall 11 is connected to the second wall 12 on either side of its width direction Z, and at least one second wall 12 is connected to the drive assembly 30.

[0091] By connecting the drive assembly 30 to the second wall 12, which intersects with the first wall 11, interference between the drive assembly 30 and the shield 20 can be effectively prevented. The layout is reasonable and easy to assemble.

[0092] Specifically, the drive unit 31, the guide rail 321, and the housing 33 are all connected to the second wall 12.

[0093] In some implementations, one of the two second walls 12 is connected to a drive assembly 30, and the shield 20 can be driven by a drive assembly 30 to adjust its position, which helps to reduce costs and save space.

[0094] In other embodiments, both second walls 12 are connected to drive components 30, and the blocking member 20 can be driven by the two drive components 30 to adjust its position, which helps to improve the stability of the movement of the blocking member 20 and the accuracy of the position adjustment.

[0095] In some alternative embodiments, the shielding member 20 is a plate-shaped structure arranged parallel to the first wall 11, and the distance between the shielding member 20 and the first wall 11 in the thickness direction X is greater than or equal to 3 mm and less than or equal to 7 mm.

[0096] It should be noted that the shielding member 20 has a first surface and a second surface facing opposite directions along the thickness direction X. The first surface is disposed facing the first wall 11, and the second surface is disposed facing the diaphragm. Both the first surface and the second surface are disposed parallel to the first wall 11. There is a uniform gap between the shielding member 20 and the first wall 11 to prevent interference between them and to accommodate the possible thermal expansion of the first wall 11.

[0097] To prevent friction or scratching between the shield 20 and the first wall 11 of the nozzle body 10 during movement, the shield 20 can be spaced apart from the first wall 11 along the thickness direction X, which helps to improve the service life of the nozzle device 1.

[0098] For example, the distance between the shielding member 20 and the first wall 11 along the thickness direction X can be, but is not limited to, any one of 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, and 7mm.

[0099] If this spacing value is set too small, i.e., less than 3mm, the shielding member 20 will be too close to the first wall 11, and interference may still exist between them. Furthermore, the high-temperature airflow ejected from the air outlet 111 will directly impact the shielding member 20, which may easily cause damage or even failure of the shielding member 20. On the other hand, if this spacing value is set too large, i.e., greater than 7mm, the shielding member 20 will be too far from the first wall 11. The high-temperature airflow ejected from the air outlet 111 will flow directly to the coating area of ​​the film after being shielded by the shielding member 20, which will accelerate the drying rate of the coating area. This will cause a large difference in the drying rate between the coating area and the blank area on the film, which may easily cause wrinkles or cracks between the coating area and the blank area.

[0100] Therefore, the nozzle device 1 provided in some embodiments of this application, by setting the distance between the shielding member 20 and the first wall 11 in the thickness direction X between 3mm and 7mm, including two endpoint values ​​of 3mm and 7mm, can not only prevent interference between the shielding member 20 and the first wall 11, thereby improving the service life of the nozzle device 1, but also balance the drying rate of the coating area and the blank area on the diaphragm, reducing the occurrence of wrinkles or cracks in the diaphragm, thereby improving the forming quality of the electrode sheet.

[0101] In some alternative embodiments, the distance between the shielding member 20 and the first wall 11 is greater than or equal to 4 mm and less than or equal to 6 mm.

[0102] The nozzle device 1 provided in some embodiments of this application further improves the service life of the nozzle device 1 and also improves the forming quality of the electrode sheet by further setting the spacing between 4mm and 6mm and including two endpoint values ​​of 4mm and 6mm.

[0103] like Figure 1 As shown, in some embodiments, at least two of the multiple air outlets 111 are spaced apart along the length direction Y, and the size of any one of the air outlets 111 is smaller than the size of the shield 20.

[0104] By setting it in the above manner, it can be ensured that the shielding member 20 can completely block the air outlet 111. Specifically, the position of the shielding member 20 can be adjusted by the driving member 31 to set the size of the area that it can block the air outlet 111, which is beneficial to improving the flexibility and versatility of the nozzle device 1.

[0105] like Figure 1 As shown, in some alternative embodiments, at least two of the plurality of air outlets 111 are spaced apart along the width direction Z of the first wall 11, and the shielding member 20 protrudes from the air outlet 111 on either side along the width direction Z.

[0106] By setting it in the above manner, the shielding member 20 can block all the air outlets 111 arranged along the width direction Z, so as to completely block the air outlets 111 opposite to all the blank areas on the diaphragm, which is beneficial to improving the reliability of the nozzle device.

[0107] Please see Figure 4 This application also provides an oven device, including a chamber 2 and a nozzle device 1 provided in any of the above embodiments, wherein the nozzle device 1 is disposed inside the chamber 2.

[0108] Among them, there can be multiple air nozzle devices 1, and multiple air nozzle devices 1 are installed inside the housing 2.

[0109] The diaphragm can enter the housing 2 through the inlet 21 and exit through the outlet 22. The direction from the inlet 21 to the outlet 22 can be understood as the direction of movement of the diaphragm, and can also be understood as the width direction Z of the first wall 11 of the nozzle body 10, that is, the width direction of the nozzle device 1.
