Description

Technical Field

[0001] The present application relates to the technical field of drying equipment, and in particular to an oven air nozzle, an oven device and an oven system. Background Art

[0002] New energy batteries are being used more and more widely in life and industry. For example, new energy vehicles equipped with batteries have been widely used. In addition, batteries are also being increasingly used in energy storage fields.

[0003] In the process of manufacturing the electrode assembly in the battery, the drying speed of the active material on the electrode assembly is often accelerated by blowing air to the electrode assembly. However, in the process of blowing air to dry the electrode assembly, the edge area of ​​the electrode assembly is prone to curling or cracking. Utility Model Content

[0004] The present application provides an oven air nozzle, an oven device and an oven system. The oven air nozzle can reduce problems such as winding or cracking of the electrode sheet during the drying process of the electrode sheet, which is beneficial to improving the processing quality of the electrode sheet.

[0005] In the first aspect, the present application provides an oven air nozzle, which includes: a shell, an isolating member, and an air guide member. The shell has an air inlet at one end and an air outlet at the other end, and the air outlet and the air inlet are connected through a ventilation cavity formed by the shell; the isolating member is connected to the shell and is located in the ventilation cavity, and the isolating member isolates the ventilation cavity into at least two air outlet spaces, and the extension direction of the isolating member satisfies a parallel relationship with a first direction, and the first direction is the arrangement direction of the air inlet and the air outlet; an air guide member is arranged in at least one air outlet space, and the guide portion of the air guide member close to the air outlet extends at an angle to the first direction.

[0006] The oven air nozzle provided in the embodiment of the present application has an isolating member disposed in the shell, and the ventilation cavity in the shell can be divided into at least two independent air outlet spaces by the isolating member. In at least one air outlet space, an air guide is disposed, and the air guide portion on the air guide has an angle with the arrangement direction of the air inlet and the air outlet on the shell, so that the direction of the air flow blown out from the air outlet space provided with the air guide can be changed by the air guide. In this way, when the oven air nozzle is used to blow air to the pole piece to dry the pole piece, the multiple air outlet spaces in the shell can be made to correspond to different areas on the pole piece, respectively, so that the air guide can be used to make the air flow blowing to different areas on the pole piece have different angles with the pole piece. For example, the airflow blowing toward the middle area of ​​the pole piece can be made nearly perpendicular to the pole piece, and the airflow blowing toward the edge area of ​​the pole piece can be made to form an acute angle with the pole piece and flow toward the edge of the pole piece through the air guide. This not only makes the airflow blowing toward the edge area of ​​the pole piece blow onto the pole piece in a gentler manner, which helps to slow down the drying speed of the edge area of ​​the pole piece, thereby reducing the occurrence of cracking in the edge area of ​​the pole piece; the airflow blowing toward the edge area of ​​the pole piece can also apply pressure to the edge area of ​​the pole piece, which helps to suppress the warping of the edge area of ​​the pole piece, thereby reducing the occurrence of winding problems in the edge area of ​​the pole piece. Therefore, the oven air nozzle provided in the embodiment of the present application can reduce the problems of winding or cracking of the pole piece during the drying process of the pole piece, which is beneficial to improving the processing quality of the pole piece.

[0007] In a possible implementation of the present application, along the arrangement direction of the at least two air outlet spaces, an end of the air guide portion close to the air outlet is closer to the shell than an end of the air guide portion far from the air outlet.

[0008] In the technical solution of the present application, since the end of the guide portion close to the air outlet is closer to the shell than the end away from the air outlet, the guide portion can make the airflow be blown out at an acute angle to the first direction in a direction away from the center of the air outlet, so that the airflow blown to the edge of the pole piece waiting to be dried The object flows to the edge away from the object to be dried, which is beneficial to quickly remove moisture from the object to be dried through the airflow; and a relatively gentle force can be applied to the edge of the object to be dried, which is beneficial to keep the edge of the object to be dried flat.

[0009] In a possible implementation of the present application, a plurality of air guides are spaced apart in the same air outlet space, and angles between adjacent air guides and the first direction increase successively from the isolating member to the shell wall of the shell.

[0010] In the technical solution of the present application, since the angles between adjacent guide parts and the first direction increase successively from the isolation part to the shell wall, the airflow blown out from the air outlet space where the guide part is set close to the side of the air outlet space where the guide part is not set can be nearly parallel to the direction of the airflow blown out from the air outlet space where the guide part is not set, and the angles between the airflow blown out through multiple guide parts and the first direction can be continuously increased successively, so that the direction of the airflow can be continuously changed, which is beneficial to reducing the impact on the dried items due to large local changes in the airflow direction.

[0011] In a possible implementation of the present application, an inclined portion on the first shell wall of the shell near the air outlet extends at an angle to the first direction, and the angle between the inclined portion and the first direction is greater than the angle between the guide portion adjacent to the inclined portion and the first direction; the first shell wall is a wall on the shell that satisfies a vertical relationship with the arrangement direction of multiple air guides.

[0012] In the technical solution of the present application, since the angle between the inclined portion on the first shell wall and the first direction is greater than the angle between the guide portion adjacent to the inclined portion and the first direction, an air flow channel having an angle with the first direction can also be formed between the inclined portion and the guide portion adjacent to the inclined portion, thereby allowing the air flow close to the shell wall to be blown out from the air outlet space at an inclined angle.

[0013] In a possible implementation of the present application, the isolation member isolates the ventilation cavity into three air outlet spaces arranged in sequence, and air guide members are provided in the two air outlet spaces on both sides, and the guide parts in the two air outlet spaces on both sides extend in a direction away from the center of the shell.

[0014] In the technical solution of the present application, since the two air outlet spaces on both sides of the shell are provided with air guides, the direction of the airflow blown out of the two air outlet spaces can be changed by the air guides. Moreover, the air guides in the two air outlet spaces on both sides extend in a direction away from the center of the shell, so that the airflow blown out of the two air outlet spaces on both sides can flow in a direction away from the shell, thereby making the airflow blown out of the two air outlet spaces on both sides contact the two edge areas of the dried articles at an acute angle.

[0015] In a possible implementation of the present application, the oven air nozzle also includes a first air uniforming member, which is connected to the isolation member and is located in the middle air outlet space among the three air outlet spaces. The first air uniforming member is located close to the air outlet and has multiple first ventilation holes.

[0016] In the technical solution of the present application, since a first wind uniforming member connected to a partition is provided in the middle wind outlet space among the three wind outlet spaces, and a plurality of first ventilation holes are provided on the first wind uniforming member, an air flow can be made to enter from the air inlet of the shell into an air uniforming cavity formed by the first wind uniforming member, the partition and the shell wall, and then the air flow can be blown out of the air uniforming cavity through the plurality of first ventilation holes, thereby forming an evenly distributed air flow outside the wind outlet space located in the middle position.

[0017] In a possible implementation of the present application, a damper assembly is provided near the air inlet in the air outlet space, a portion of the damper assembly is movably connected to the shell, and the area of ​​the air inlet can be changed by adjusting the position of the damper assembly relative to the shell.

[0018] In the technical solution of the present application, since a damper assembly is provided near the air inlet in the air outlet space, the area of ​​the air inlet in the air outlet space can be changed by adjusting the position of the damper assembly relative to the shell, thereby facilitating the control of the amount of airflow entering the air outlet space, and further controlling the flow rate of the airflow blown out from each air outlet space.

[0019] In a possible implementation of the present application, the damper assembly includes a fixed member and a sliding member, both of which are provided with matching wind shielding portions, a ventilation portion is provided between adjacent wind shielding portions, the fixed member is fixedly connected to the shell, and the sliding member is slidably connected to the shell, and the position of the wind shielding portion on the sliding member relative to the ventilation portion on the fixed member can be changed by adjusting the position of the sliding member relative to the fixed member.

[0020] In the technical solution of the present application, since the sliding part can slide relative to the fixed part, the sliding part can be moved relative to the fixed part to change the shielding area of ​​the wind shield part on the sliding part to the ventilation part on the fixed part, thereby changing the area of ​​the channel through which the airflow of the air outlet space enters, and further controlling the flow rate of the airflow blown out from the air outlet space.

[0021] The second aspect of the present application provides an oven device, comprising: a box body and an oven air nozzle provided by any one of the first aspects above, wherein one end of the box body has an air flow inlet and the other end has an opening; at least two oven air nozzles are movably arranged in the box body, the air flow inlet is connected to the air inlet, and the air outlet faces the opening.

[0022] The oven device provided by the present application, because it includes the oven nozzle provided by the first aspect, can make the airflows blown out from different air outlet spaces in the oven nozzle blow to the dried objects at different angles. Therefore, when the oven device is used to blow air to multiple pole pieces to dry the pole pieces, the problems of the pole pieces winding or cracking during the drying process can be reduced, which is conducive to improving the processing quality of the pole pieces.

[0023] In a possible implementation of the present application, the oven device further includes a sliding assembly, which is fixed on the oven body, and the oven air nozzle is slidably connected to the sliding assembly.

[0024] In the technical solution of the present application, since the oven air nozzle is installed in the box body through a sliding assembly, it is convenient to adjust the position of the oven air nozzle in the box body according to the position of the dried objects so that the oven air nozzle is relatively positioned with the dried objects.

[0025] In a possible implementation of the present application, the oven device further includes a control component, which is connected to the oven body, and a sliding member in a damper assembly in the oven air nozzle is connected to the control component, and the control component can drive the sliding member to move relative to the shell.

[0026] In the technical solution of the present application, since a control component is provided on the box body and the sliding part in the damper assembly is connected to the control component, the position of the sliding part relative to the fixed part can be adjusted through the control component, thereby adjusting the flow rate of the air flow blown out from the oven air nozzle.

[0027] In a possible implementation of the present application, the control assembly includes a threaded rod and a nut matching the threaded rod, the threaded rod is rotatably disposed on the box body, the nut is sleeved on the threaded rod and connected to the sliding member.

[0028] In the technical solution of the present application, since the threaded rod is rotatably set on the box body and the nut is connected to the sliding part, the nut can be moved along the threaded rod by rotating the threaded rod, so that the sliding part can be driven by the nut to move relative to the fixed part, thereby changing the size of the channel area of ​​the airflow entering from the air inlet to the air outlet space.

[0029] In a possible implementation of the present application, a seal is provided between two adjacent oven air nozzles and between the oven air nozzle and the box body. The seal can be deformed as the oven air nozzle moves relative to the box body, and the seal is used to block the air flow.

[0030] In the technical solution of the present application, since a seal is provided in the box, the space between the oven air nozzles in the box and between the oven air nozzle and the box can be blocked by the seal. Furthermore, the seal is provided as a structure that can be deformed with the movement of the oven air nozzle, so that in the process of adjusting the position of the oven air nozzle relative to the box, the seal can always maintain a good blocking effect on some spaces inside the box.

[0031] In a possible implementation of the present application, the oven device also includes a second air uniforming member, which is arranged in the box body and located between the oven air nozzle and the air flow inlet. The box body and the second air uniforming member are combined to form an air uniforming cavity, and the second air uniforming member has a plurality of second ventilation holes.

[0032] In the technical solution of the present application, since a second air uniforming member is provided in the box body, an air uniforming chamber can be formed in the box body through the second air uniforming member. In this way, after the air flow enters the box body through the air flow inlet, the air flow can first fill the air uniforming chamber, and then the air flow from the air uniforming chamber through the second ventilation hole on the second air uniforming member enters the oven nozzle, so that the air flow can enter the oven nozzle in a relatively stable manner.

[0033] The third aspect of the present application provides an oven system, comprising: an oven plenum and an oven device provided by any one of the second aspects above; wherein the oven plenum has a plurality of air flow outlets; each box body is detachably connected to the oven plenum, and the air flow inlet on each box body is respectively connected to the air flow outlet.

Therefore, when the oven device is used to blow air to multiple pole pieces to dry the pole pieces, the problems of winding or cracking of the pole pieces during the drying process can be reduced, which is conducive to improving the processing quality of the pole pieces.

Therefore, they should not be understood as limitations on the embodiments of the present application.

[0054] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements.

[0056] During the manufacturing process of the electrode assembly in the battery, the active material is usually coated on the surface of the current collector of the electrode assembly by a coating device. The active material is usually a slurry. After the active material is coated on the current collector by the coating device, a pole piece is formed. The strip-shaped pole piece can be dried to increase the drying speed of the active material on the current collector, thereby improving the processing efficiency.

[0057] In the related art, the drying speed of the active material is usually accelerated by blowing hot air to the pole piece. In the process of blowing air to the active material, the strip-shaped pole piece moves continuously along the belt-feeding direction, and the active material is blown with an air nozzle adapted to the width of the pole piece. Although it can speed up the drying speed of the active material, it is also easy to cause the pole piece to be wound, bent, or even cracked during the drying process due to the different drying speeds of the active materials in various areas of the pole piece. In particular, the edge of the active material coating area on the pole piece may shake due to the influence of the airflow during the belt-feeding process. The shaking of the pole piece will aggravate the cracking of the pole piece after drying, thereby affecting the processing quality of the pole piece.

[0058] The present application embodiment provides a drying oven air nozzle, referring to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the oven air nozzle provided in this application. Figure 2 The cross-sectional schematic diagram of the oven nozzle provided in the present application. The oven nozzle provided in the embodiment of the present application can improve the drying efficiency of the electrode sheet, and can also reduce the problems such as winding or cracking of the electrode sheet, which is beneficial to improve the processing quality of the electrode sheet. For the convenience of description and explanation, the oven nozzle provided in the embodiment of the present application is described below by taking the electrode sheet in the battery as an example, but it does not limit the oven nozzle to only be used for drying the electrode sheet. The oven nozzle provided in the embodiment of the present application can be used to blow air to any applicable product.

[0059] The oven air nozzle provided in the embodiment of the present application comprises: a shell 11, an isolating member 12 and an air guide member 13. Among them, one end of the shell 11 has an air inlet 111, and the other end has an air outlet 112, and the air outlet 112 and the air inlet 111 are connected through a ventilation cavity formed by the shell 11; the isolating member 12 is connected to the shell 11 and is located in the ventilation cavity, and the isolating member 12 isolates the ventilation cavity into at least two air outlet spaces, and the extension direction of the isolating member 12 satisfies a parallel relationship with the first direction Z, and the first direction Z is the arrangement direction of the air inlet 111 and the air outlet 112; an air guide member 13 is arranged in at least one air outlet space, and the guide portion 131 of the air guide member 13 close to the air outlet 112 extends at an angle to the first direction Z.

[0060] In the embodiment of the present application, the shell 11 can provide an installation position for other parts in the oven nozzle, and can enclose a cavity for air flow. For example, the shell 11 can be set to a cylindrical structure, such as setting the shell 11 to a cylindrical shape that is approximately rectangular, that is, there are two openings 22 at opposite ends of the shell 11, one opening 22 can be used as an air inlet 111, and the other opening 22 can be used as an air outlet 112, and the area between the air inlet 111 and the air outlet 112 in the shell 11 is a ventilation cavity. The airflow enters the ventilation cavity from the air inlet 111, passes through the air outlet 112 and blows out of the shell 11, so that the range of space occupied by the airflow blown out from the air outlet 112 can be limited by setting the size and shape of the shell 11. For example, the width of the shell 11 can be set to match the width of the active material on the pole piece 9, such as the width of the shell 11 is greater than the width of the active material and less than the width of the pole piece 9.

[0061] In the present application embodiment, Figure 2 As shown, an isolating member 12 may be provided in the housing 11, so as to isolate and divide the ventilation cavity in the housing 11 into at least two air outlet spaces through the isolating member 12. For example, the isolating member 12 may be provided as a sheet-like structure, so that the two ends of the sheet-like isolating member 12 along the tape-running direction Y of the pole piece 9 are respectively fixedly connected to the inner wall of the housing 11, and the sheet-like isolating member 12 extends along the arrangement direction of the air inlet 111 and the air outlet 112, that is, the isolating member 12 extends along the first direction Z. At the same time, the isolating member 12 may be extended along the tape-running direction Y, that is, the isolating member 12 may be provided as a thin flat plate.

[0062] Exemplarily, two thin flat-plate-shaped isolators 12 may be disposed in the shell 11, such as fixing the two isolators 12 on the inner wall of the shell 11 in a nearly parallel manner, and allowing a distance between the two isolators 12, so that the ventilation cavity is divided into three air outlet spaces by the two isolators 12. For example, the distance between the two isolators 12 may be set according to the width of the side touch area 92 and the central membrane area 91 on the pole piece 9, that is, the width between the isolator 12 and the shell wall of the shell 11 is nearly consistent with the width of the side touch area 92, so that the distance between the two isolators 12 is also nearly consistent with the width of the central membrane area 91. Thereby, the airflow flowing from the air outlet space between the two isolators 12 can be blown onto the central membrane area 91, and the airflow flowing from the two air outlet spaces located on both sides can be blown onto the side touch area 92. Among them, as Figure 1As shown, along the tape running direction Y perpendicular to the pole piece 9, the side touch area 92 of the pole piece 9 is the area where the active material on the pole piece 9 is located at the edge, and the central film area 91 of the pole piece 9 is the area where the active material on the pole piece 9 is located in the middle. For example, the side touch area 92 is usually an area within a width range of 20 mm to 40 mm at the edge of the active material. In this way, there are two side touch areas 92 and one central film area 91 on the pole piece 9.

[0063] In the embodiment of the present application, an air guide 13 may be provided in the housing 11 to guide and change the flow direction of the airflow in the air outlet space through the air guide 13. The air guide 13 may be provided as a thin sheet structure, for example, the air guide 13 may be provided as a thin sheet including a flow guide portion 132 and a flow guide portion 131. The flow guide portion 132 and the flow guide portion 131 may have an angle of 10° to 60°, that is, the flow guide portion 132 is extended along the first direction Z, and the flow guide portion 131 is extended at an angle of 10° to 60° with the first direction Z; and the flow guide portion 132 is located in the air outlet space near the air inlet 111, and the flow guide portion 131 is located in the air outlet space near the air outlet 112.

[0064] Exemplarily, in the case where there are three air outlet spaces in the housing 11, air guides 13 may be provided in the air outlet spaces on both sides in the width direction X perpendicular to the tape running direction Y. In this way, the direction of the airflow blown out from the air outlet space provided with the air guide 13 may be changed by the air guide 13, so that the airflow may be blown onto the pole piece 9 in a direction not perpendicular to the pole piece 9.

[0065] The oven air nozzle provided in the embodiment of the present application has a partition 12 disposed in the shell 11, and the ventilation cavity in the shell 11 can be divided into at least two independent air outlet spaces by the partition 12. In addition, an air guide 13 is disposed in at least one air outlet space, and the air guide portion 131 on the air guide 13 has an angle with the arrangement direction of the air inlet 111 and the air outlet 112 on the shell 11, so that the direction of the air flow blown out from the air outlet space provided with the air guide 13 can be changed by the air guide 13. In this way, when the oven air nozzle is used to blow air to the pole piece 9 to dry the pole piece 9, the multiple air outlet spaces in the shell 11 can be made to correspond to different areas on the pole piece 9 respectively, so that the air guide 13 can be used to make the air flow blowing to different areas on the pole piece 9 have different angles with the pole piece 9. For example, the airflow blowing toward the middle area of ​​the pole piece 9 can be made nearly perpendicular to the pole piece 9, and the airflow blowing toward the edge area of ​​the pole piece 9 can be made to form an acute angle with the pole piece 9 and flow toward the edge of the pole piece 9 through the air guide 13. In this way, not only the airflow blowing toward the edge area of ​​the pole piece 9 is blown onto the pole piece 9 in a relatively gentle manner, which helps to slow down the drying speed of the edge area of ​​the pole piece 9, thereby reducing the occurrence of cracking in the edge area of ​​the pole piece 9; pressure can also be applied to the edge area of ​​the pole piece 9 by the airflow blowing toward the edge area of ​​the pole piece 9, which helps to suppress the warping of the edge area of ​​the pole piece 9, thereby reducing the occurrence of winding problems in the edge area of ​​the pole piece 9. Therefore, the oven air nozzle provided in the embodiment of the present application can reduce the problems of winding or cracking of the pole piece 9 during the drying process of the pole piece 9, which helps to improve the processing quality of the pole piece 9.

[0066] In some possible embodiments of the present application, Figure 2 As shown, along the arrangement direction of the at least two air outlet spaces, an end of the air guide portion 131 close to the air outlet 112 is closer to the housing 11 than an end of the air guide portion 131 away from the air outlet 112 .

[0067] In the embodiment of the present application, the direction of the airflow after being blown out from the air outlet space can be controlled by setting the inclination direction of the air guide portion 131 of the air guide member 13. That is, along the arrangement direction of the plurality of air outlet spaces (such as Figure 2 The airflow passing through the guide portion 131 can be inclined relative to the first direction Z toward the center of the air outlet 112 as shown in the width direction X of the shell 11, or the airflow passing through the guide portion 131 can be inclined relative to the first direction Z toward the center of the air outlet 112.

[0068] For example, the airflow passing through the air guide portion 131 can be made to flow in a direction away from the center of the air outlet 112. For example, along the width direction X of the housing 11, the air guide portion 131 on the air guide member 13 can be made to tilt in a direction away from the center of the air outlet 112. In this way, the end of the air guide portion 131 close to the air outlet 112 will be closer to the shell wall of the housing 11 than the end of the air guide portion 131 away from the air outlet 112.

[0069] In the above embodiment, since the end of the guide portion 131 close to the air outlet 112 is closer to the shell 11 than the end away from the air outlet 112, the guide portion 131 can make the airflow be blown out at an acute angle to the first direction Z in a direction away from the center of the air outlet 112, so that the airflow blown to the edge of the pole piece 9 where the object to be dried is waiting to flow to the edge away from the object to be dried, which is conducive to quickly removing moisture from the object to be dried through the airflow; and a relatively gentle force can be applied to the edge of the object to be dried, which is conducive to keeping the edge of the object to be dried flat.

[0070] In some possible embodiments of the present application, Figure 2 As shown, a plurality of air guides 13 are arranged at intervals in the same air outlet space, and the angles between adjacent air guides 131 and the first direction Z increase successively from the isolation member 12 to the shell wall of the shell 11 .

[0071] In the embodiment of the present application, at least two air guides 13 can be set in the air outlet space of the oven air nozzle where the air guide 13 is required, and a gap of a certain distance is reserved between two adjacent air guides 13 so that the two adjacent air guides 13 are arranged at intervals.

[0072] For example, Figure 2 As shown, the guide portion 132 and the guide portion 131 of each air guide member 13 located in the same air outlet space may have different angles. Figure 2 The width direction X shown in the figure), that is, the direction from the center of the shell 11 to the shell wall of the shell 11, can make the guide part 131 on each air guide member 13 tilt more and more toward the shell wall in sequence, so that the angle between adjacent guide parts 131 and the first direction Z gradually increases in sequence. In this way, the angle between the airflow blown out between the two guide parts 131 closer to the center of the shell 11 and the pole piece 9 is closer to 90°, and the angle between the airflow blown out between the two guide parts 131 farther away from the center of the shell 11 and the pole piece 9 is closer to 30°. It should be noted that the degree to which the angle between two adjacent guide parts 131 and the first direction Z increases in sequence can be set according to actual needs, and the embodiments of the present application are not limited to this.

[0073] In the above embodiment, since the angles between adjacent guide portions 131 and the first direction Z increase successively from the isolation member 12 to the shell wall, the airflow blown out from the air outlet space where the guide portion 131 is provided can be close to the side of the air outlet space where the guide portion 131 is not provided, and the direction of the airflow blown out from the air outlet space where the guide portion 131 is not provided can be nearly parallel to the direction of the airflow blown out from the air outlet space where the guide portion 131 is not provided, and the angles between the airflow blown out through multiple guide portions 131 and the first direction Z can be continuously increased successively, so that the direction of the airflow can be continuously changed, which is beneficial to reduce the impact on the dried items due to large local changes in the airflow direction.

[0074] In some possible embodiments of the present application, the inclined portion 114 on the first shell wall 113 of the shell 11 near the air outlet 112 extends at an angle to the first direction Z, and the angle between the inclined portion 114 and the first direction Z is greater than the angle between the guide portion 131 adjacent to the inclined portion 114 and the first direction Z; the first shell wall 113 is a wall on the shell 11 that satisfies a vertical relationship with the arrangement direction of the multiple air guide members 13.

[0075] In the present application embodiment, Figure 2 As shown, at least a portion of the shell wall of the shell 11 can also be set to have an angle with the first direction Z, so that a channel for guiding the change of the airflow direction is also formed between the air guide portion 131 of the air guide member 13 adjacent to the shell wall and the shell wall. For example, an inclined portion 114 can be set on the first shell wall 113, and the portion of the first shell wall 113 close to the air inlet 111 is aligned with the arrangement direction of the plurality of air guide members 13 ( Figure 2 The width direction X) shown in FIG is perpendicular or nearly perpendicular to the width direction X).

[0076] Exemplarily, along the arrangement direction of the plurality of air guides 13, the air guide portion 131 is inclined toward the shell wall on one side of the shell 11, and the inclined portion 114 on the first shell wall 113 near the air outlet 112 can be set to have an angle with the first direction Z, and the angle between the inclined portion 114 and the first direction Z is greater than the angle between the air guide portion 131 adjacent to the inclined portion 114 and the first direction Z. That is, the inclined portion 114 can also be regarded as an air guide portion 131, and the angles between all the air guide portions 131 and the first direction Z increase successively from the isolation member 12 to the shell wall of the shell 11.

[0077] In the above embodiment, since the angle between the inclined portion 114 on the first shell wall 113 and the first direction Z is greater than the angle between the guide portion 131 adjacent to the inclined portion 114 and the first direction Z, an air flow channel having an angle with the first direction Z can also be formed between the inclined portion 114 and the guide portion 131 adjacent to the inclined portion 114, so that the air flow close to the shell wall can also be blown out from the air outlet space at an inclined angle.

[0078] In some possible embodiments of the present application, Figure 2 As shown, the isolation member 12 isolates the ventilation cavity into three air outlet spaces arranged in sequence, and the two air outlet spaces on both sides are provided with air guide members 13, and the guide parts 131 in the two air outlet spaces on both sides extend in a direction away from the center of the shell 11.

[0079] In an embodiment of the present application, the shell 11 can be divided into three air outlet spaces by an isolating member 12, and the three air outlet spaces are arranged in sequence. For example, two isolating members 12 can be set in the shell 11 along the width direction X of the shell 11. The two sheet-shaped isolating members 12 divide the shell 11 into three independent spaces to form three air outlet spaces. The air inlets 111 of the three air outlet spaces are connected, and the air outlets 112 of the three air outlet spaces are independent of each other.

[0080] For example, along the width direction X of the housing 11, the two isolation members 12 can be respectively arranged at a position close to one third of the width of the housing 11 (the width of the housing 11 at one end close to the air outlet 112). For example, the air guide members 13 can be arranged in the two air outlet spaces on both sides of the three air outlet spaces, and the air guides 131 in the two air outlet spaces on both sides can be extended in an inclined direction away from the center of the housing 11. That is, Figure 2 As shown, the air guide 131 in the first air outlet space 115 on the left is inclined toward the first shell wall 113 on the left side of the housing 11, the air guide 131 in the second air outlet space 116 on the right is inclined toward the first shell wall 113 on the right side of the housing 11, and the air guide 13 is not provided in the third air outlet space 117 in the middle. In this way, the airflow blown out of the air outlet space in the middle among the three air outlet spaces will flow along the first direction Z, the airflow blown out of the air outlet space on the left among the three air outlet spaces will flow obliquely to the left, and the airflow blown out of the air outlet space on the right among the three air outlet spaces will flow obliquely to the right.

[0081] In the above embodiment, since the two air outlet spaces on both sides of the housing 11 are provided with air guides 13, the directions of the airflows blown out of the two air outlet spaces can be changed by the air guides 13. Moreover, the air guides 131 in the two air outlet spaces on both sides extend in a direction away from the center of the housing 11, so that the airflows blown out of the two air outlet spaces on both sides can flow in a direction away from the housing 11, thereby making the airflows blown out of the two air outlet spaces on both sides contact the two edge areas of the dried articles at acute angles.

[0082] In some possible embodiments of the present application, Figure 2As shown, the oven air nozzle also includes a first air uniforming member 14, which is connected to the isolation member 12 and is located in the middle air outlet space among the three air outlet spaces. The first air uniforming member 14 is located close to the air outlet 112, and has a plurality of first ventilation holes extending along the first direction Z.

[0083] In the embodiment of the present application, a first air uniforming member 14 may be provided for the middle air outlet space among the three air outlet spaces, so that an air uniforming cavity is formed in the middle air outlet space through the first air uniforming member 14 and the isolation member 12 .

[0084] Exemplarily, a first air leveling member 14 may be provided on one end of the two isolating members 12 near the air outlet 112, and an air leveling chamber may be formed by enclosing the two isolating members 12, the first air leveling member 14 and the shell wall of the shell 11. For example, a plurality of first vents may be provided on the first air leveling member 14, and the plurality of first vents may be evenly distributed on the first air leveling member 14, such as providing the first vents as circular through holes, and having equal or nearly equal distances between two adjacent first vents. The first vents may be formed by extending along the first direction Z.

[0085] In another example, the two isolating members 12 and the first air leveling member 14 can be set as an integrated structure, for example, a stainless steel sheet can be used to form an approximately U-shaped structure by stamping, the bottom of the U-shaped structure serves as the first air leveling member 14, and the two side walls of the U-shaped structure serve as the two isolating members 12. The two isolating members 12 and the first air leveling member 14 can also be set as a separate structure, such as by welding or other methods to fix the two isolating members 12 and the first air leveling member 14.

[0086] In the above embodiment, since a first wind uniforming member 14 connected to the isolation member 12 is provided in the middle wind outlet space among the three wind outlet spaces, and a plurality of first ventilation holes are provided on the first wind uniforming member 14, the airflow can enter from the air inlet 111 of the shell 11 into the wind uniforming cavity formed by the first wind uniforming member 14, the isolation member 12 and the shell wall of the shell 11, and then the airflow blows out of the wind uniforming cavity through the plurality of first ventilation holes, thereby forming a uniformly distributed airflow outside the wind outlet space located in the middle position.

[0087] In some possible embodiments of the present application, Figure 1 and Figure 2 As shown, a damper assembly 15 is provided near the air inlet 111 in the air outlet space, and a portion of the damper assembly 15 is movably connected to the shell 11. By adjusting the position of the damper assembly 15 relative to the shell 11, the area of ​​the air inlet 111 can be changed.

[0088] In the embodiment of the present application, a damper assembly 15 may be provided at a position near the air outlet 112 in the housing 11, so as to control the size of the airflow entering each air outlet space from the air outlet 112 through the damper assembly 15. For example, in the case where there are three air outlet spaces in the housing 11, an independent damper assembly 15 may be provided for each air outlet space, so as to control the size of the airflow entering the three air outlet spaces through the three damper assemblies 15 respectively.

[0089] For example, a part of the damper assembly 15 can be connected to the housing 11 by a rotation connection, a sliding connection, etc. In this way, when it is necessary to adjust the area size of the air outlet space near the air inlet 111, the damper assembly 15 can be used to change the area size of the air inlet 111 by rotating or sliding a part of the damper assembly 15 relative to the housing 11, thereby changing the area size of the channel for the airflow from the air inlet 111 to the air outlet space, thereby controlling the size of the airflow entering the air outlet space.

[0090] In the above embodiment, since the damper assembly 15 is provided near the air inlet 111 in the air outlet space, the area of ​​the air inlet 111 in the air outlet space can be changed by adjusting the position of the damper assembly 15 relative to the shell 11, thereby facilitating the control of the amount of airflow entering the air outlet space, and further the flow rate of the airflow blown out from each air outlet space.

[0091] In some possible embodiments of the present application, refer to Figure 3 , Figure 4 and Figure 5 , Figure 3 Schematic diagram of the air door assembly 15 in the oven air nozzle provided in this application Figure 1 , Figure 4 Schematic diagram of the air door assembly 15 in the oven air nozzle provided in this application Figure 2 , Figure 5 Schematic diagram of the air door assembly 15 in the oven air nozzle provided in this application Figure 3 The damper assembly 15 includes a fixing member 151 and a sliding member 152. The fixing member 151 and the sliding member 152 are both provided with matching windshields 153. A ventilation portion 154 is provided between adjacent windshields 153. The fixing member 151 is fixedly connected to the housing 11, and the sliding member 152 is slidably connected to the housing 11. By adjusting the position of the sliding member 152 relative to the fixing member 151, the position of the windshield 153 on the sliding member 152 relative to the ventilation portion 154 on the fixing member 151 can be changed.

[0092] In the present application embodiment, Figure 3 , Figure 4 and Figure 5As shown, the damper assembly 15 can be configured to have a structure including a fixing member 151 and a sliding member 152. The fixing member 151 can be fixed on the shell 11, and the sliding member 152 can be slidably connected to the shell 11, so as to change the area of ​​the air inlet 111 of the air outlet space by adjusting the position of the sliding member 152 relative to the fixing member 151.

[0093] Exemplarily, the fixing member 151 can be set in a sheet shape, and the windshield 153 and the ventilation part 154 can be alternately arranged on the sheet-shaped fixing member 151, the windshield 153 can be a plurality of convex strips, and the ventilation part 154 can be a through hole, a notch, etc. located between adjacent convex strips, such as setting the ventilation part 154 to be an approximately rectangular notch. Correspondingly, the sliding member 152 can also be set in a sheet shape, and the windshield 153 and the ventilation part 154 can be alternately arranged on the sheet-shaped sliding member 152, the windshield 153 can also be a convex strip, the convex strip on the sliding member 152 and the width and length of the notch on the fixing member 151 are matched respectively, and the ventilation part 154 can be a through hole, a notch, etc. In this way, the fixing member 151 can be fixed on the housing 11 in a direction perpendicular to the first direction Z, and the fixing member 151 is located near the air inlet 111 in the air outlet space, and the sliding member 152 can be overlapped with the fixing member 151, and the sliding member 152 can be slidably arranged on the housing 11.

[0094] like Figure 3 As shown, when the air inlet 111 needs to be opened to the maximum, the sliding member 152 can be moved relative to the fixing member 151 along the width direction X so that the ventilation portion 154 on the sliding member 152 and the ventilation portion 154 on the fixing member 151 face each other, so that the air inlet 111 can have the maximum air inlet area. Figure 4 As shown, when the air inlet 111 needs to be reduced in size, the sliding member 152 can be moved relative to the fixing member 151 along the width direction X so that the wind shielding portion 153 on the sliding member 152 blocks at least a portion of the ventilation portion 154 on the fixing member 151 in the first direction Z, so that the air inlet 111 can have a smaller air inlet area. Figure 5 As shown, when the air inlet 111 needs to be closed, the air inlet 111 can be closed by moving the sliding member 152 relative to the fixing member 151 along the width direction X so that the ventilation portion 154 on the sliding member 152 completely covers the ventilation portion 154 on the fixing member 151.

[0095] In the above embodiment, since the sliding member 152 can slide relative to the fixed member 151, the sliding member 152 can be moved relative to the fixed member 151 to change the shielding area of ​​the ventilation portion 154 on the fixed member 151 by the wind shielding portion 153 on the sliding member 152, thereby changing the area of ​​the channel through which the airflow of the air outlet space enters, and further controlling the flow rate of the airflow blown out from the air outlet space.

[0096] In addition, the present application also provides a drying oven device, referring to Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the structure of the oven device provided in this application. Figure 7 The cross-sectional schematic diagram of the oven device provided in the present application. The oven device comprises: a box body 2 and an oven air nozzle 1 provided in any one of the above embodiments. The box body 2 has an air flow inlet 21 at one end and an opening 22 at the other end; at least two oven air nozzles 1 are movably arranged in the box body 2, the air flow inlet 21 is connected to the air inlet 111, and the air outlet 112 faces the opening 22.

[0097] In the embodiment of the present application, the box body 2 is used to carry and install the oven nozzle 1, and the box body 2 can also serve as a gas passage. For example, the box body 2 can be set to a structure approximately in the shape of a rectangular parallelepiped, and the box body 2 has a cavity inside.

[0098] For example, Figure 6 As shown, along the first direction Z, an airflow inlet 21 may be provided on one side wall of the box body 2, such as two airflow inlets 21 may be provided on the same wall of the box body 2. An opening 22 may be provided on the other side wall of the box body 2 opposite to the airflow inlet 21, so that the airflow enters the box body 2 from the airflow inlet 21 and flows to the outside of the box body 2 from the opening 22.

[0099] In another example, a connector 23 may be provided on one side of the box body 2 where the air inlet 21 is provided, so that the box body 2 can be installed at a corresponding workstation through the connector 23. For example, the connector 23 may be a quick-release lock, or a hook, or a fastener such as a bolt.

[0100] In the present application embodiment, Figure 7 As shown, at least two oven nozzles 1 can be arranged in the box body 2. For example, at least two oven nozzles 1 can be arranged in sequence in the width direction X of the shell 11 in the box body 2, and each oven nozzle 1 can be arranged in the box body 2 in a movable manner. If the oven nozzle 1 is arranged in the box body 2 by sliding connection, the position of the oven nozzle 1 in the box body 2 can be adjusted. When the oven nozzle 1 is installed in the box body 2, the air inlet 111 of the oven nozzle 1 can be connected to the air flow inlet 21 of the box body 2, and the air outlet 112 of the oven nozzle 1 is facing the opening 22 of the box body 2.

[0101] For example, the number of oven air nozzles 1 provided in the box 2 can be determined according to the number of strip-shaped electrode sheets 9. For example, when three electrode sheets 9 are carried in parallel, three oven air nozzles 1 can be provided side by side in the box 2, and each oven air nozzle 1 corresponds to one electrode sheet 9. Then, the three oven air nozzles 1 can be used to blow air to the three electrode sheets 9 respectively, so as to speed up the drying speed of the active material on the electrode sheets 9.

[0102] The oven device provided in the embodiment of the present application includes the oven nozzle 1 provided in the above embodiment, so that the airflows blown out from different air outlet spaces in the oven nozzle 1 can be blown onto the dried objects at different angles. Therefore, when the oven device is used to blow air to a plurality of pole pieces 9 to dry the pole pieces 9, problems such as winding or cracking of the pole pieces 9 during the drying process can be reduced, which is conducive to improving the processing quality of the pole pieces 9.

[0103] In some possible embodiments of the present application, refer to Figure 8 and Fig. 9 , Figure 8 This is a schematic diagram of an exploded view of the oven device provided in this application. Fig. 9 Provided for this application Figure 8 The partial enlarged schematic diagram of the A part in the middle. The oven device also includes a sliding component 3, the sliding component 3 is fixed on the box body 2, and the oven nozzle 1 is slidably connected to the sliding component 3.

[0104] In the embodiment of the present application, the oven air nozzle 1 can be installed in the box body 2 in a sliding connection manner, so as to adjust the installation position of the oven air nozzle 1 relative to the box body 2. For example, a slide bar 31 can be provided in the box body 2, and the slide bar 31 can be provided in the box body 2 along the width direction X of the shell 11. Correspondingly, a through hole matching the slide bar 31 can be provided on the shell wall of the shell 11, and the slide bar 31 can be penetrated on the shell 11 so that the oven air nozzle 1 can slide relative to the box body 2 through the slide bar 31. A clamp 32 can also be provided on the slide bar 31, and the clamp 32 is sleeved on the slide bar 31, and the clamp 32 is fixedly connected to the shell wall of the shell 11. The clamp 32 can be clamped and fixed on the slide bar 31 by adjusting the tightness of the screw on the clamp 32, so as to fix the oven air nozzle 1 on the slide bar 31.

[0105] In the above embodiment, since the oven nozzle 1 is installed in the box body 2 through the sliding assembly 3, it is convenient to adjust the position of the oven nozzle 1 in the box body 2 according to the position of the dried objects so that the oven nozzle 1 is relatively positioned with the dried objects.

[0106] In some possible embodiments of the present application, Figure 8 and Fig. 9As shown, the oven device further includes a control component 4, which is connected to the box body 2, and a sliding member 152 in the air door component 15 in the oven air nozzle 1 is connected to the control component 4, and the control component 4 can drive the sliding member 152 to move relative to the shell 11.

[0107] In an embodiment of the present application, a control component 4 may be provided in the oven device to control the position of the sliding member 152 in the damper assembly 15 relative to the fixing member 151 through the control component 4, so as to control the flow rate of the air flow blown out from the oven air nozzle 1.

[0108] For example, when the oven air nozzle 1 includes three air door assemblies 15, two groups of control assemblies 4 can be arranged in the box body 2, and the two air door assemblies 15 located on both sides of the oven air nozzle 1 are connected to the same group of control assemblies 4, and the air door assembly 15 located in the middle of the oven air nozzle 1 is connected to another group of control assemblies 4. For example, the control assembly 4 is slidably arranged on the box body 2, and the sliding member 152 in the air door assembly 15 is driven to move relative to the fixing member 151 by pushing and pulling the control assembly 4.

[0109] In the above embodiment, since the control component 4 is provided on the box body 2 and the sliding member 152 in the damper assembly 15 is connected to the control component 4, it is convenient to adjust the position of the sliding member 152 relative to the fixing member 151 through the control component 4, so that the flow rate of the air flow blown out from the oven air nozzle 1 can be adjusted.

[0110] In some possible embodiments of the present application, Fig. 9 As shown, the control assembly 4 includes a threaded rod 41 and a nut 42 matched with the threaded rod 41 . The threaded rod 41 is rotatably arranged on the box body 2 , and the nut 42 is sleeved on the threaded rod 41 and connected to the sliding member 152 .

[0111] In the embodiment of the present application, the control component 4 may use a threaded rod 41 and a nut 42. For example, an external thread may be provided on the threaded rod 41 at a position adjacent to each oven air nozzle 1, and the threaded rod 41 may be rotatably provided on the housing 2, and the extension direction of the threaded rod 41 is consistent with the arrangement direction of the plurality of oven air nozzles 1. The nut 42 may be sleeved on the threaded rod 41, and the nut 42 may be connected to the external thread, and the nut 42 may be fixedly connected to the sliding member 152 in the damper assembly 15. In this way, in the process of rotating the threaded rod 41, the nut 42 is restricted from rotating by the sliding member 152, but the nut 42 may move on the threaded rod 41 along the axis of the threaded rod 41, so that the sliding member 152 may be driven by the nut 42 to move relative to the fixing member 151. For example, a scale line may be provided on the housing 2, and the rotation angle of the threaded rod 41 may be observed through the scale line, so as to control the size of the passage area of ​​the airflow entering the air outlet space from the air inlet 111 by controlling the rotation angle of the threaded rod 41.

[0112] In the above embodiment, since the threaded rod 41 is rotatably set on the box body 2, and the nut 42 is connected to the sliding member 152, the nut 42 can be moved along the threaded rod 41 by rotating the threaded rod 41, so that the sliding member 152 can be driven by the nut 42 to move relative to the fixing member 151, thereby changing the size of the channel area for the airflow to enter the air outlet space from the air inlet 111.

[0113] In some possible embodiments of the present application, Figure 7 As shown, a seal 5 is provided between two adjacent oven air nozzles 1 and between the oven air nozzle 1 and the box body 2. The seal 5 can be deformed as the oven air nozzle 1 moves relative to the box body 2. The seal 5 is used to block the flow of air.

[0114] In the embodiment of the present application, a seal 5 may be provided in the box 2 to seal the space in the box 2 where no airflow is required. The oven nozzle 1 may move relative to the box 2, so that the size and shape of the space in the box 2 where no airflow is required may change.

[0115] Exemplarily, the seal 5 can be made of a deformable structure or material. For example, the seal 5 can be set to a structure similar to an organ, that is, by pulling the seal 5, the seal 5 can be lengthened, and by compressing the seal 5, the seal 5 can be shortened. Alternatively, the seal 5 can also be made of a sheet or block material with elasticity. In this way, the seal 5 can be set between two adjacent oven nozzles 1, so that the oven nozzle 1 and the box 2 can be provided with seals 5, and the two ends of some seals 5 can be connected to the two adjacent oven nozzles 1, and the two ends of other seals 5 can be connected to the box 2 and the oven nozzle 1. In the process of adjusting the position of the oven nozzle 1 relative to the box 2, the seal 5 can be deformed with the movement of the oven nozzle 1, so that the seal 5 is always used to block the space between the adjacent oven nozzles 1 and the space between the oven nozzle 1 and the box 2, so that the airflow enters the box 2 from the air inlet 21 and enters the oven nozzle 1 as completely as possible.

[0116] In the above embodiment, since the sealing member 5 is provided in the box body 2, the space between the oven nozzles 1 in the box body 2 and between the oven nozzle 1 and the box body 2 can be blocked by the sealing member 5. Furthermore, the sealing member 5 is configured to be deformable with the movement of the oven nozzle 1. In the process of adjusting the position of the oven nozzle 1 relative to the box body 2, the sealing member 5 can also always maintain a good blocking effect on some spaces inside the box body 2.

[0117] In some possible embodiments of the present application, Figure 7As shown, the oven device also includes a second air uniforming member, which is arranged in the box body 2 and located between the oven air nozzle 1 and the air flow inlet 21. The box body 2 and the second air uniforming member are enclosed to form an air uniforming cavity, and the second air uniforming member has a plurality of second ventilation holes.

[0118] In the embodiment of the present application, a second air uniforming member may be provided in the box body 2 to form an air uniforming chamber in the box body 2 through the second air uniforming member, so that the air flow can enter each oven air nozzle 1 at a uniform speed through the air flow inlet 21.

[0119] Exemplarily, a second air leveling member may be provided at a position near the air inlet 21 in the box body 2, the second air leveling member may adopt a flat plate structure, and a plurality of second ventilation holes may be provided on the second air leveling member, and the second ventilation holes may be circular through holes. The second air leveling member may be fixedly connected to the box wall of the box body 2, and the second air leveling member may be perpendicular or nearly perpendicular to the first direction Z. Then, a uniform air cavity may be formed on one side of the box body 2 near the air inlet 21 through the second air leveling member, and the uniform air cavity is connected to the air inlet 21, and is connected to the air inlet 111 of the oven air nozzle 1 through the second ventilation hole.
