[0030] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0031] When the pole piece is being formed, it can go through the processes of coating, drying, rolling, cutting, etc. For example, after the surface of the pole piece is coated with active slurry, it enters an oven with a nozzle, and the nozzle is used to blow air to dry the surface of the pole piece. Since the drying rate of the middle part of the pole piece along its width direction is lower than the drying rate of the edge part, during the blowing and drying process, different parts of the pole piece along its width direction will be dried to different degrees, such as over-drying at the edge part of the pole piece along its width direction, which will cause the pole piece to crack.

[0032] Based on this, in order to solve the problem of cracking on the pole piece due to uneven drying, the present application proposes a nozzle mechanism, in which at least two air outlet channels are arranged on the nozzle body, and different air outlet channels are used to blow and dry different parts of the pole piece. Since the air volume in at least one air outlet channel can be adjusted by an adjustment component, the air volume in the air outlet channel is adjusted according to the drying conditions of different parts of the pole piece, so that different air volumes appear on different parts of the pole piece, improving the drying uniformity on the pole piece, thereby effectively reducing the probability of cracking.

[0033] According to some embodiments of this application, please refer to Figure 1 The present application provides a nozzle mechanism 100, which includes a nozzle body 10 and an adjustment component 20. The nozzle body 10 has at least two air outlet channels 13, and the adjustment component 20 is disposed on the nozzle body 10. Among all the air outlet channels 13, the air outlet volume of at least one air outlet channel 13 can be adjusted by the adjustment component 20.

[0034] The air outlet channel 13 refers to the structure of the nozzle body 10 that can blow air to the pole piece, and its shape can be designed in various ways, such as but not limited to square, oval, etc., or irregular shapes. The number of air outlet channels 13 can be two, three, four or more; at the same time, the air outlet channels 13 can be separated from each other, or can be connected to each other to form a complete gap structure.

[0035] Among all the air outlet channels 13, there may be one air outlet channel 13 whose air volume can be adjusted; or the air volume of multiple air outlet channels 13 can be adjusted; of course, all the air outlet channels 13 can also be adjusted individually. When the air volume of only one air outlet channel 13 can be adjusted, if the adjustable air outlet channel 13 is aimed at the middle part of the pole piece, the drying rate of the middle part of the pole piece can be accelerated by increasing the air volume of the air outlet channel 13. If the adjustable air outlet channel 13 is aimed at the edge of the pole piece, the drying rate of different parts of the pole piece can be kept consistent by reducing the air volume of the air outlet channel 13, thereby improving the drying uniformity of the pole piece.

[0036] There are many ways to distribute the air outlet channels 13, for example, they can be arranged at only one end of the nozzle body 10, or at both opposite ends of the nozzle, etc., as long as different air outlet channels 13 can act on different parts of the pole piece along its width direction. Of course, in some embodiments, when blowing and drying, at least three air outlet channels 13 can be distributed in sequence along the width direction of the pole piece, two of which correspond to the two edges of the pole piece, and one of which corresponds to the middle part of the pole piece.

[0037] The adjustment component 20 refers to a structure that can change the air volume in the air outlet channel 13. There are many ways to change the air outlet, for example: the size of the air outlet end 131 of the air outlet channel 13 can be changed by driving at least one inner wall of the air outlet channel 13 to operate; or, the adjustment component 20 is at least partially located in the air outlet channel 13, and the airflow in part of the air outlet channel 13 is shielded or blocked by rotation or movement.

[0038] In addition, the number of the adjusting components 20 can be one or more. When the number of the adjusting components 20 is more than one, the adjusting components 20 and the air outlet passages 13 can be arranged one to one.

[0039] With such a design, the air volume in the air outlet channel 13 is adjusted according to the drying conditions of different parts of the electrode, so that different air volumes appear on different parts of the electrode, improving the drying uniformity on the electrode, thereby effectively reducing the probability of cracking.

[0040] According to some embodiments of the present application, optionally, please refer to Figure 2 The nozzle body 10 includes an air outlet body 11 and at least two air guides 12, each of which is disposed on the air outlet body 11 and forms an air outlet channel 13 with the air outlet body 11. At least one of the air guides 12 is connected to an adjustment component 20, which is used to drive the air guide 12 to move closer to or away from the air outlet body 11 to change the air volume of the air outlet channel 13 where the air guide 12 is located.

[0041] The air guide member 12 and the air outlet body 11 respectively refer to two structures constituting the air outlet channel 13. The air outlet method of the air outlet channel 13 can be to supply air to the air outlet channel 13 through the airflow in the air outlet body 11, and then the pole piece is blown dry by the air outlet channel 13; or, it can also be connected to the air outlet channel 13 through a pipeline, and air is supplied to the air outlet channel 13 by the pipeline.

[0042] The air guide 12 may be designed to be movable relative to the air outlet body 11, or may be designed to be fixed. The movable air guide 12 may perform corresponding movements under the action of the adjustment component 20, for example, when the air guide 12 moves toward the air outlet body 11, the air outlet passage 13 between the air guide 12 and the air outlet body 11 is reduced; when the air guide 12 moves away from the air outlet body 11, the air outlet passage 13 between the air guide 12 and the air outlet body 11 is expanded.

[0043] Among them, there are many ways in which the adjustment component 20 drives the air guide member 12 to move, for example: when the adjustment component 20 is a cylinder, an electric cylinder or a hydraulic cylinder, the air guide member 12 can be driven to move closer to or away from the air outlet body 11 through the telescopic shaft; or, when the adjustment component 20 is a combination structure of a screw rod and a slider, the slider is driven to move by rotating the screw rod, thereby driving the air guide member 12 to move accordingly; or, when the adjustment component 20 is a combination structure of a gear and a rack, the rotating gear can drive the rack to reciprocate to achieve the corresponding movement of the air guide member 12, etc.

[0044] In addition, the air guide 12 can be arranged at one end of the air outlet body 11, or at both ends of the air outlet body 11. At the same time, in order to enable the air outlet of the air nozzle mechanism 100 to stably act on different parts of the pole piece, multiple air guides 12 can be arranged in sequence along the width direction of the pole piece. For example, the middle part of the pole piece along its own width direction can correspond to at least one air guide 12, and the edge part of the pole piece along its own width direction can correspond to at least one air guide 12, etc.

[0045] Such a design introduces the air guide 12 and the air outlet body 11, so that the adjustment component 20 can adjust the air volume in the air outlet channel 13, thereby facilitating uniform drying and further reducing the probability of cracking of the electrode due to drying.

[0046] According to some embodiments of the present application, optionally, please refer to Figure 3 and Figure 4 The adjustment assembly 20 includes an adjustment member 21 and a matching member 22 that is transmission-connected to the adjustment member 21. The adjustment member 21 is disposed on the air outlet body 11. At least one air guide member 12 is connected to the matching member 22. The adjustment member 21 is configured to drive the matching member 22 to drive the corresponding air guide member 12 to move closer to or away from the air outlet body 11 when rotating around its own axis 212.

[0047] The adjusting member 21 refers to a structure that can drive the matching member 22 to move by rotating around its own axis 212. It can be designed as a screw structure or a gear. When the adjusting member 21 is designed as a screw structure, the matching member 22 can be threadedly sleeved on the screw structure. At this time, when the screw structure rotates, it can drive the matching member 22 to move back and forth, thereby driving the air guide 12 to move closer to or away from the air outlet body 11. When the adjusting member 21 is designed as a gear, the matching member 22 can be designed as a rack matching it, and the gear rotation drives the rack to move back and forth to achieve the corresponding movement of the air guide 12.

[0048] In order to drive the air guide member 12 to move stably, the matching member 22 needs to be connected to the air guide member 12, and the connection method may be but is not limited to interference fit, bolt connection, clamping, pin connection, welding, bonding, etc.

[0049] With such a design, the transmission mode between the adjusting member 21 and the matching member 22 is designed to be a rotary drive, which makes it easier to adjust the air volume of the air outlet channel 13 and improves the air outlet adjustment efficiency; at the same time, the rotary adjustment mode also facilitates the precise adjustment of the air volume, which is beneficial to improving the drying quality of the electrode.

[0050] According to some embodiments of the present application, optionally, please refer to Figure 4 The adjusting member 21 is provided with an external thread 211 , and the matching member 22 is threadedly sleeved on the external thread 211 .

[0051] The external thread 211 refers to the structure around the outer periphery of the axis 212 of the adjusting member 21. When the adjusting member 21 rotates around its own axis 212, the matching member 22 can move back and forth along the axis 212 under the action of the external thread 211, thereby realizing the movement of the air guide member 12. It can be known that the matching member 22 is threadedly sleeved on the external thread 211, which means that the matching member 22 also has an internal thread that matches with it.

[0052] The size of the external thread 211 along the axis 212 can determine the movement of the air guide 12, which can affect the adjustment of the air volume in the air outlet channel 13. Of course, the size of the external thread 211 along the axis 212 can be set according to the actual air volume.

[0053] With such a design, the external thread 211 is utilized to convert the rotation of the adjusting member 21 into a reciprocating movement on the matching member 22 , thereby facilitating the adjustment of the air volume in the air outlet channel 13 and improving the convenience of operation.

[0054] According to some embodiments of the present application, optionally, please refer to Figure 4 The adjustment component 20 also includes an operating member 24 , and the operating member 24 is disposed on the adjustment member 21 .

[0055] The operating member 24 is a structure that allows the operator to hold and rotate the adjusting member 21, and its shape can be designed to be disc-shaped, cylindrical, or rod-shaped. The connection between the operating member 24 and the adjusting member 21 can be, but is not limited to, bolt connection, threaded sleeve connection, pin connection, welding, riveting, clamping, bonding, etc.

[0056] Such a design introduces the operating member 24, which is convenient for the operator to operate by hand, saves time and effort, facilitates the rotation of the adjustment member 21, and improves the efficiency of adjusting the air volume.

[0057] According to some embodiments of the present application, optionally, please refer to Figure 2 The air nozzle body 10 further includes a mounting seat 14 , which is disposed on the air outlet body 11 , and one end of the adjusting member 21 is rotatably disposed on the mounting seat 14 .

[0058] The mounting seat 14 refers to a structure that can support and allow the adjustment member 21 to rotate. The mounting seat 14 can be mounted on the air outlet body 11 by, but not limited to, bolt connection, clamping, pin connection, riveting, welding, bonding, etc. At the same time, one end of the adjustment member 21 can be rotatably arranged on the mounting seat 14, and its mounting method can be a shaft-hole matching method, that is, a mounting hole is set on the mounting seat 14, and one end of the adjustment member 21 can be rotatably inserted into the mounting hole; or, one end of the adjustment member 21 is fixed to the mounting seat 14 through a bearing 23 or other structures.

[0059] With such a design, the mounting seat 14 is introduced, so that the adjusting member 21 is stably supported, so that the adjusting member 21 can rotate stably to effectively adjust the air volume in the air outlet channel 13 .

[0060] According to some embodiments of the present application, optionally, please refer to Figure 4 The adjusting component 20 further includes a bearing 23, and a groove 141 is provided on the mounting seat 14. The bearing 23 is arranged in the groove 141, and one end of the adjusting member 21 is fixed on the bearing 23.

[0061] The bearing 23 refers to a structure that supports the adjusting member 21 and allows the adjusting member 21 to rotate smoothly, and may include an outer ring, an inner ring, and a ball disposed between the inner ring and the outer ring, wherein one end of the adjusting member 21 is fixed in the inner ring. To increase the service life of the bearing 23, the material of the bearing 23 may be a high temperature resistant material, such as H370 steel material.

[0062] With such a design, the adjusting member 21 is mounted on the mounting seat 14 via the bearing 23 , which reduces friction during rotation, allowing the adjusting member 21 to rotate smoothly, thereby facilitating improved adjustment accuracy of the air outlet channel 13 .

[0063] According to some embodiments of the present application, optionally, please refer to Figure 1Among the air outlet body 11 and the air guide member 12 connected to the adjustment component 20, one of them is provided with a guide protrusion 30, and the other is provided with a guide hole 31 for the guide protrusion 30 to pass through.

[0064] When adjusting the air volume, the air guide 12 moves toward or away from the air outlet body 11. During the movement, the guide protrusion 30 and the guide hole 31 cooperate with each other, so that the movement of the air guide 12 is more stable. Between the same air guide 12 and the adjustment component 20, the number of the guide protrusion 30 and the guide hole 31 can be one or more.

[0065] For specific embodiments, please refer to Figure 4 The guide protrusion 30 is provided on the mounting seat 14 on the air outlet body 11, and the guide hole 31 is provided on the air guide member 12 connected to the adjustment assembly 20. The connection method of the guide protrusion 30 on the air outlet body 11 can be, but is not limited to, bolt connection, clamping, riveting, welding, pin connection, bonding, etc.

[0066] With such a design, the cooperation between the guide protrusion 30 and the guide hole 31 makes the movement of the air guide member 12 relative to the air outlet body 11 more stable, thereby facilitating the improvement of the adjustment accuracy of the air outlet volume.

[0067] According to some embodiments of the present application, optionally, please refer to Figure 2 Each air guide member 12 includes a support 121 and an air guide portion 122. The support 121 is located on one side of the air outlet body 11. The air guide portion 122 is disposed on the support 121 and protrudes toward one side of the air outlet body 11. An air outlet channel 13 is formed between the air guide portion 122 and the air outlet body 11. The support 121 of at least one air guide member 12 is connected to the adjustment assembly 20.

[0068] The support 121 refers to a structure connected to the adjustment component 20. During adjustment, the support 121 can drive the air guide 122 to move toward or away from the air outlet body 11. An air outlet channel 13 can be formed between the air guide 122 and the air outlet body 11. When the air guide 122 moves toward the air outlet body 11 with the support 121, the air outlet channel 13 between the air guide 122 and the air outlet body 11 is reduced; when the air guide 122 moves away from the air outlet body 11 with the support 121, the air outlet channel 13 between the air guide 122 and the air outlet body 11 is expanded.

[0069] The air guide 122 and the support 121 may be an integrated structure or a combined structure. For example, the two may be connected by bolt connection, clamping, pin connection, riveting, bonding, welding, etc.

[0070] The air guide portion 122 is disposed on the support 121 and protrudes toward one side of the air outlet body 11, so that a receiving space 123 can be formed between the air guide portion 122 and the support 121. When one end of the adjustment member 21 is rotatably disposed on the mounting seat 14, the receiving space 123 can accommodate at least a portion of the mounting seat 14, so that the air guide portion 122 will not collide with the mounting seat 14 during the adjustment process.

[0071] In addition, in order to allow the airflow to be blown out of the air outlet channel 13 at a certain angle, the side surface of the air guide portion 122 facing the air outlet body 11 includes an air guide surface 12a, and the air guide surface 12a is inclined, and the end of the air guide surface 12a close to the air outlet end 131 of the air outlet channel 13 can be closer to or farther away from the air outlet body 11. When the end of the air guide surface 12a close to the air outlet end 131 of the air outlet channel 13 is closer to the air outlet body 11, the wind blown out of the air outlet channel 13 flows toward one side of the air outlet body 11; when the end of the air guide surface 12a close to the air outlet end 131 of the air outlet channel 13 is closer to the air outlet body 11, the wind blown out of the air outlet channel 13 flows away from one side of the air outlet body 11.

[0072] With such a design, the air guide portion 122 and the support 121 are introduced to facilitate the adjustment of the air volume in the air outlet channel 13 .

[0074] During the air drying process, the airflow of the air cavity 111 enters the air outlet channel 13 through the connecting port 112; and then the air is blown toward the pole piece from the air outlet end 131 of the air outlet channel 13. To facilitate the air supply to the air cavity 111, an opening 113 connected to the air cavity 111 is provided on the air outlet body 11. At the same time, in order to filter and disperse the blown-in air, a partition 114 can be provided on the cavity wall of the air cavity 111. The partition 114 is separated between the opening 113 and the connecting port 112, and a plurality of perforations 11a are provided on the partition 114. In this way, the air entering from the opening 113 enters the air cavity 111 through the perforations 11a on the partition 114, and then enters the air outlet channel 13 from the connecting port 112 on the air cavity 111.

[0075] With such a design, the air cavity 111 and the connecting port 112 are provided on the air outlet body 11, so as to facilitate the air supply to the air outlet channel 13, so that the drying of the electrode piece can be carried out stably.

[0077] The air outlet channel 13 can be arranged at one end of the nozzle body 10, or at opposite ends of the nozzle body 10. When the air outlet channels 13 are arranged at opposite ends of the nozzle body 10, the air outlet channels 13 at both ends can be arranged one-to-one or staggered.

[0078] In addition, at one end of the nozzle body 10 along the preset direction X, the number of the air outlet channels 13 may not be limited to Figure 1 The eight in it can also be other numbers, such as: three, four, five, six, etc.

[0079] For specific embodiments, please refer to Figure 2 The air guides 12 are arranged at opposite ends of the nozzle body 10 along the preset direction X, and at either end of the nozzle body 10 along the preset direction X, the air guides 12 are sequentially distributed along a direction intersecting the preset direction X. At the same time, when the nozzle mechanism 100 dries the pole piece, the preset direction X intersects with the width direction of the pole piece, for example, the preset direction X is perpendicular to the width direction of the pole piece.

[0080] With such a design, the air outlet channels 13 are reasonably distributed on the nozzle body 10, so as to facilitate blowing and drying different parts of the electrode, so as to improve the drying efficiency and drying uniformity.
