Description

Technical Field

[0001] The present application relates to the technical field of lithium battery production, and particularly to a feeding die head device and a coating system. Background Art

[0002] In the production of battery electrodes, it is necessary to coat a slurry on the electrode substrate, and the slurry forms a thin film on the surface of the electrode to improve the performance of the electrode. Currently, the coating production of battery electrodes is carried out using a coating die head. Since the structural characteristics of the die head are closely related to the coating effect of the thin film, the structural improvement of the die head has attracted more and more attention from all equipment and process developers.

[0003] In the related art, the die head is generally a single-layer coating structure. Although the die head with a single-layer coating structure has a simple structure, is convenient for die change, and has low operation requirements, however, with the development of electric vehicles, the performance requirements for batteries are getting higher and higher, and the electrode materials have changed from single performance to multiple performances. For example, multiple layers of thin films with different properties need to be coated on the electrode. For example, to improve the instantaneous charge and discharge ability and enhance the conductivity, an active material containing conductivity needs to be coated on the electrode; in the scenario of a high potential platform, an active material with high nickel also needs to be coated.

[0004] However, in the multi-layer coating device in the related art, due to structural limitations, thin films with different properties can only be coated layer by layer successively, that is, after one layer is coated, another layer is coated. Since there are differences in the curing time for successive coating of different slurries, it is easy for the electrode coating to show a delamination phenomenon. Summary of the Utility Model

[0045] The technical solutions of the embodiments of the present application will be described in detail below with reference to the drawings.

[0046] Figure 1 is a perspective view of a feeding die head device shown in an embodiment of the present application; Figure 2 is a rear view of a feeding die head device shown in an embodiment of the present application.

[0047] See Figure 1 and Figure 2 The present application provides a feeding die head device, including:

[0048] A die head main body 100, the die head main body 100 includes a plurality of die head components stacked and connected in sequence. For example, Figure 2 the shown die head components A, B, and C. The die head component is provided with a cavity for accommodating the slurry. The cavities of the plurality of die head components are spaced apart for accommodating different types of slurries; wherein, each of the die head components is composed of two monomer die heads. For example, Figure 1 the shown die head component A is composed of a first monomer die head and a second monomer die heads 101 and 103. A diversion component is provided between the two monomer die heads; on one side of the die head main body 100, there are a plurality of feed ports 110 ([[]] Figure 1 shows the feed port 110 of the die head component A) corresponding to and communicating with the cavities in the plurality of die head components one by one. On the other side of the die head main body 100, there is an outlet port 120, and the cavities of the plurality of die head components are all communicated with the outlet port 120.

[0049] In the feeding die head device provided by the present application, different slurries in the cavities of the plurality of die head components can converge at the outlet port 120 and be simultaneously discharged from the outlet port, so as to be able to perform simultaneous coating of multiple slurries, making the curing times of multiple slurries consistent, and avoiding the defect of easy delamination caused by differences in curing times when different slurries are coated successively in the related art.

[0050] In the present application, the plurality of feed ports 110 are connected to the feeding equipment of the coating system through feeding pipelines, and the feeding equipment is used to respectively input different types of slurries into the cavities in the plurality of die head components. In some specific implementation manners, the number of die head components is at least three, and the die head main body includes three cavities that can accommodate three different slurries.

[0051] In some embodiments, the outlet port 120 extends along the length direction of the die head main body 100, and the outlet port 120 is also called a lip.

[0052] In some embodiments, the diversion component may be a sheet-like component disposed between two single die heads, also referred to as a gasket. The sheet-like component is provided with a preset shape for guiding the slurry in the corresponding cavity out of the discharge port in a specific coating form.

[0053] On the two opposite sides of the die head body 100 are a rotation connection part and a discharge part respectively. For example, the rotation connection part is arranged at the rear side and the discharge part is arranged at the front side, and the discharge port 120 is arranged at the discharge part.

[0054] In some embodiments, the plurality of die head assemblies are formed by sequentially stacking and connecting a number of single die heads. Each single die head is provided with a cavity. The cavities of every two adjacent single die heads face each other, jointly combining to form a cavity for accommodating the slurry. The cavities of the plurality of die head assemblies are independently arranged.

[0055] The die head body further includes a die head flipping mechanism 300, a fixing component, and a die head connection component 200.

[0056] The die head flipping mechanism 300 includes a plurality of flipping components. Every two adjacent single die heads are rotationally connected by the flipping components. Among them, the plurality of flipping components are arranged on the same side of the die head body. For example, the plurality of flipping components are arranged at the rotation connection part, and two adjacent single die heads can be flipped. The fixing component includes a plurality of fixing pieces, and every two adjacent single die heads are detachably connected by the fixing component; the die head connection component 200 includes connection parts arranged in a plurality of two and a plurality of connecting pieces respectively cooperating with a plurality of connection holes. The plurality of connecting pieces are used to sequentially connect two by two a plurality of single die heads. When two adjacent single die heads are flipped, it does not affect the connection state of other die head assemblies, which is beneficial to replacing the diversion component.

[0057] The solution provided by the present application, with a plurality of die head assemblies matched and combined, can simultaneously perform the coating of multiple slurries, avoiding the defect of easy delamination in the related art when coating layer by layer successively. Moreover, the structure is more simplified, which is more conducive to mass production. In addition, through the design of the superposition and cooperation of the multi-layer die head assemblies and the diversion component, the multi-layer die head assemblies can be flipped with each other and are detachably connected two by two, realizing the rapid disassembly, installation, and type change of the diversion component, saving production time.

[0058] In this embodiment, a plurality of single die heads are stacked in the height direction Z of the cuboid. After the plurality of single die heads are assembled, the final form of the die head body 100 is a cuboid, which can match the installation and fixation of the existing coating system unit die head on site, without the need to transform the existing coating system, and can reduce costs.

[0059] The rotating connection part and the discharge port 120 are respectively located on both sides of the long side of the cuboid; the mating surface between adjacent single die heads or the guiding component is inclined with respect to the height direction Z of the die head body 100. The discharge part is provided with a discharge port 120 extending along the length direction Y of the cuboid, and the discharge ends of the cavities of multiple die head assemblies converge at the discharge port 120. The longitudinal section of each single die head is generally triangular, and the sizes of each single die head or the volumes of the cavities can be set differently according to actual requirements, and thus the inclination angles of the mating surfaces of multiple single die heads are also different.

[0060] See Figure 2 , in some embodiments, the flipping assembly can be a hinge provided at the rear side of the single die head, but is not limited thereto, and can also be a matching structure of a rotating shaft and a shaft hole. By providing a hinge at the rear side of the single die head, the flipping function of any layer of single die heads is realized, and the rapid die change of multiple layers of guiding components can be achieved, so as to adapt to different coating requirements and save production time.

There are two groups of the second connection parts, and the two groups of the second connection parts are located on both sides in the width direction X of the die head body 100.

[0063] In some embodiments, the first connection part and / or the second connection part includes connection holes opened in multiple die head assemblies and multiple connecting rods respectively matched with the multiple connection holes. The connection holes of adjacent die head assemblies are aligned, and the multiple connecting rods are used to connect multiple die head assemblies in sequence pairwise. The connection holes are opened at the edges of the die head assemblies, and each connection hole is used to connect adjacent die head assemblies in different layers. After being arranged like this, a locking structure with different steps can be realized by the edge dislocation design of multiple layers of die head assemblies, so as to fix between the components of the die head.

[0064] In some embodiments, the die head connection assembly 200 further includes a whole die connection hole provided in multiple die head assemblies and a whole die connection part matched with the whole die connection hole. The whole die connection part is used to connect multiple die head assemblies into a whole, so that the fixation of the whole die head can be realized.

[0065] In some embodiments, the connection hole and the connecting rod are in threaded cooperation. For example, the connection hole is a threaded hole and the connecting rod is a screw rod.

[0066] In some embodiments, there are two first connecting parts arranged in the length direction Y of the die head body 100, and the connecting holes of the two first connecting parts are symmetrical, ensuring the fixed installation and structural stability between the individual die heads.

Among them, the first fixing member 3001 on the back, the first fixing member 3002 on the side cooperate with the first flipping component 3007 to realize the flipping and fixing of the first single die head 101 and the second single die head 103; the second fixing member 3003 on the back, the second fixing member 3004 on the side cooperate with the second flipping component 3008 to realize the flipping and fixing of the second single die head 103 and the third single die head 105; the third fixing member 3005 on the back, the third fixing member 3006 on the side cooperate with the third flipping component to realize the flipping and fixing of the third single die head 105 and the fourth single die head 107.

[0081] In some embodiments, a flipping rod 108 is further provided at the top of the die head body 100. The flipping rod 108 extends in the vertical direction, and the number of the flipping rods 108 can be two, which can be fixed on the left and right sides of the first single die head 101.

[0082] See Figures 1 - 6 , the structure of this embodiment can realize the disassembly, assembly and type replacement of the quick flow guiding component. Taking the disassembly and assembly of the second flow guiding component 104 as an example, first take out the horizontal integral die connecting rods 20040 on the left and right sides and the vertical integral die connecting rods 20050, and take out the horizontal second connecting rod 20020 and the vertical second connecting rod 20070, so that the second flow guiding component 104 is separated from the second single die head 103 and the third single die head 105. At this time, the other single die heads still remain as a whole under the connection of the corresponding connecting rods. Then take out the second fixing member 3003 on the back and the second fixing member 3004 on the side, so that the second single die head 103 and the third single die head 105 are completely separated. The user operates the top die flipping rod 108 to act on the second flipping component 3008 on the back, so as to realize the overall flipping of the first single die head 101 and the second single die head 103 relative to the third single die head 105 and the fourth single die head 107 by more than 130°, so as to quickly take out the second flow guiding component 104.

[0083] In this embodiment, the installation process of the second flow guiding component 104 is opposite to the above disassembly process. The disassembly and assembly processes of the first flow guiding component 102 and the third flow guiding component 106 are the same as those of the second flow guiding component 104, and will not be elaborated here.

[0084] The solution of this application can realize the flipping function of any single die heads of each layer by designing fixing members and flipping components on the back and side of the die head body 100, and can realize the quick disassembly, assembly and type replacement of multiple layers of flow guiding components, which can effectively save production time and improve production efficiency.
