Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery manufacturing equipment technology, and in particular to a gasket and coating equipment for adjusting coating size. Background Technology
[0002] Lithium-ion battery coating is a crucial step in lithium-ion battery manufacturing, significantly impacting battery performance, lifespan, and safety. However, due to variations in lithium-ion battery manufacturing materials and formulations, the viscosity and solid content of the produced slurry are unstable, frequently leading to issues such as poor electrode thinning or thick edges during the coating process.
[0003] Currently, the common method to solve this problem is to replace the gaskets with different models. However, due to the high cost of gaskets, production sites often require a single gasket to meet the needs of multiple sizes and different slurries, making it difficult to effectively guarantee the quality of the electrode sheets. Existing gaskets are mainly designed for specific coating sizes of a particular product. When the coating size needs to be changed, it is often necessary to purchase redesigned gaskets. This not only leads to long gasket procurement cycles and high costs, but also makes it inconvenient for actual production applications.
[0004] Furthermore, existing gaskets lack flexibility and adjustability. They cannot be quickly adjusted to meet different coating requirements, which limits the improvement of production efficiency and the optimization of product quality. At the same time, the inability to precisely control the coating size also increases raw material waste and production costs.
[0005] Another problem is that existing gaskets are difficult to adapt to slurries with different viscosities and solid contents. This means that when using slurries with different formulations, gaskets may need to be replaced frequently, increasing the complexity and time cost of the production process.
[0006] Finally, the installation and removal of gaskets in existing technologies are often cumbersome and require specialized tools and skills, which not only increases the difficulty of operation but also prolongs the time for equipment adjustment and maintenance.
[0007] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0028] The following description, in conjunction with the accompanying drawings, provides a more detailed account of a gasket for adjusting coating size and a coating device according to the present invention, illustrating preferred embodiments of the invention. It should be understood that those skilled in the art can modify the invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the scope of the invention.
[0029] In the description of this specification, terms such as "one embodiment" or "some embodiments" mean that one or more embodiments of this specification include a particular feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.
[0030] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0031] The following description, with reference to the accompanying drawings, describes a shim for adjusting the coating size according to an embodiment of the present invention.
[0032] According to an embodiment of the present invention, a shim for adjusting the coating size, such as... Figure 1 , Figure 2 As shown, it includes: a gasket body 1 and an adjusting piece 5. The gasket body 1 has an opening 7 and a positioning groove 5a inside the opening 7. The adjusting piece 5 is movably installed in the positioning groove 5a to adjust the size of the opening 7.
[0033] Specifically, after the gasket body 1 is connected to the positioning device reserved in the coating equipment, the gasket body 1 is installed and positioned. The adjusting plate 5 is installed in the positioning groove 5a and the opening size can be adjusted by adjusting and controlling the adjusting plate. The adjusting plate can be provided with adjusting teeth, and the positioning groove is provided with a tooth groove that cooperates with the adjusting teeth. The size of the opening 7 is adjusted by the precise cooperation between the adjusting teeth 5b and the tooth groove, which further realizes the adjustment of the coating size produced by the coating equipment during operation. This allows the coating equipment to produce coatings of different sizes without changing the gasket. That is, the gasket of this utility model has a wider range of use and higher efficiency than the gasket of the prior art.
[0034] In other words, by providing the positioning groove 5a at the opening 7 of the gasket body 1, the adjusting piece 5 can be installed on the positioning groove 5a and its position adjusted, thereby achieving flexible adjustment of the coating size. This solves the problem in the prior art that the gasket cannot adapt to various sizes and different slurries, improving the flexibility and efficiency of the production site. Compared with the prior art, the gasket of this utility model can adapt to different coating requirements more quickly, reducing the frequency and cost of replacing the gasket and ensuring the quality stability of the electrode.
[0035] In some embodiments of this utility model, such as Figure 1 As shown, the gasket body 1 includes a first part 2 and a second part 6. The two second parts 6 are disposed on opposite sides of the first part 2 along the extension direction. The first part and the two second parts form a concave opening structure. The positioning groove 5a is disposed at the end of the second part 6 away from the first part 2 and is disposed opposite to it.
[0036] Specifically, the arrangement of the first part 2 and the two second parts 6 determines the size of the opening 7 of the gasket body 1. The positioning grooves 5a on the second parts 2 are arranged opposite each other, and the adjusting piece 5 installed on the positioning grooves 5a can adjust the size of the opening 7 of the gasket body 1. The structural design of the opening 7 of the first part 2 and the second parts 6 can limit the coating size. Installing the adjusting piece 5 on the second parts 6 further improves the flexibility and adaptability of the gasket when adjusting the coating size. The relative arrangement of the positioning grooves 5a allows the adjusting piece 5 to be installed and adjusted more flexibly, thereby enabling the production of coatings of different sizes in conjunction with coating equipment. As a preferred embodiment, multiple positioning grooves 5a can be designed to increase the selection of the installation position of the adjusting piece 5, further improving the adaptability of the gasket. Furthermore, the shape and size of the positioning grooves 5a can be adjusted according to actual needs, for example, designed as trapezoidal or circular, to accommodate adjusting pieces 5 of different shapes and sizes.
[0037] Therefore, the design of the gasket body 1, by including the first part 2 and the second part 6, allows the positioning groove 5a to be located at the end of the second part 6 away from the first part 2 and arranged opposite to it. This structural design improves the flexibility and adaptability of the gasket when adjusting the coating size. The relative arrangement of the positioning groove 5a allows the adjusting piece 5 to be installed and adjusted more flexibly, thereby adapting to different coating size requirements. This design reduces the frequency of gasket replacement, lowers costs, and improves production efficiency. Compared with the prior art, the gasket body 1 of this utility model is more flexible in design and can better adapt to different coating size requirements, thereby improving production efficiency and reducing costs.
[0038] In some embodiments of this utility model, such as Figure 2 As shown, the adjusting plate 5 is provided with an adjusting tooth 5b with a fixed tooth pitch, and the positioning groove 5a is provided with a tooth groove (not marked in the figure) with the same tooth pitch as the adjusting tooth 5b. The adjusting tooth 5b can be adjusted to cooperate with the tooth groove.
[0039] Specifically, the adjusting piece is embedded in the positioning groove 5a along the extension direction perpendicular to the first part 2 and the extension direction of the second part 6. Multiple adjusting teeth 5b on the positioning part correspond to and engage with multiple toothed grooves in the positioning groove 5a, thereby adjusting the size of the opening 7 of the gasket body 1. For example, if multiple adjusting teeth 5b each correspond to and engage with multiple positioning grooves 5a, the opening 7 of the gasket is at its largest size. Alternatively, if one adjusting tooth 5b does not engage with one positioning groove, and the remaining adjusting teeth 5b each engage with the remaining positioning grooves 5a, the opening 7 of the gasket is reduced. That is, the size of the opening 7 of the gasket is adjusted by controlling the engagement of the adjusting teeth 5b with the positioning grooves 5a. Simultaneously, the adjusting teeth 5b on the positioning part engage with the toothed grooves in the positioning groove 5a through the same tooth pitch, ensuring high precision and stability when adjusting the installation position of the adjusting piece 5 on the positioning groove 5a. This design allows the adjusting piece 5 to be precisely adjusted in position, thereby solving the problem of the fitting accuracy between the adjusting piece 5 and the gasket body 1.
[0040] The pitch of the adjusting tooth 5b is fixed, which can be formed on the main body 5c by machining or by injection molding. The tooth groove can be formed in the positioning groove 5a by milling or laser cutting, or by injection molding. As a preferred embodiment, the pitch of the adjusting tooth 5b and the tooth groove can be designed to be between 0.5mm and 2mm to ensure sufficient accuracy and stability when the adjusting piece 5 is adjusted in the positioning groove 5a. For example, when the pitch is set to 0.5mm, the adjustment accuracy of the adjusting piece 5 is 0.5mm. In addition, the gasket body 1 also includes a limiting part (not shown in the figure), which is detachably installed at opposite ends of the second part 6 to limit and fix the adjusting piece 5 installed in the positioning groove 5a.
[0041] Therefore, by engaging the adjusting teeth 5b on the main body 5c with the grooves in the positioning groove 5a, the adjusting piece 5 is precisely adjusted on the positioning groove 5a, ensuring a high-precision fit between the adjusting piece 5 and the gasket body 1. This design not only improves the installation accuracy of the adjusting piece 5 but also enhances its stability on the positioning groove 5a, effectively solving the problem of the fitting accuracy between the adjusting piece 5 and the gasket body 1. Compared with the prior art, the technical solution of this utility model has higher precision and stability, better assisting coating equipment in producing coatings of different sizes and different slurries, improving coating quality, and reducing production problems caused by mismatched gasket sizes.
[0042] In some embodiments of this utility model, such as Figure 1 As shown, the gasket body 1 is provided with a plurality of positioning holes 3, which are evenly distributed on the second part 6.
[0043] Specifically, the gasket body 1 is positioned and installed with the coating equipment through multiple positioning holes 3. The multiple positioning holes 3 ensure the precise positioning of the gasket body 1 and the stability of the gasket body 1 after installation. The multiple positioning holes 3 on the gasket body 1 can be evenly distributed in various ways. For example, the positions and spacing of the positioning holes 3 can be pre-set on the second part 6 using precise machining techniques to ensure that the distance between each positioning hole 3 is equal. As a preferred embodiment, CNC machine tools can be used for machining to ensure the accuracy and consistency of the positioning holes 3. Furthermore, multiple evenly distributed positioning holes 3 can be formed in one step during the molding of the gasket body 1 through mold design. This not only improves production efficiency but also ensures the uniform distribution of the positioning holes 3.
[0044] In other words, by providing multiple positioning holes 3 on the gasket body 1 and ensuring that these positioning holes 3 are evenly distributed on the second part 6, the positioning problem between the gasket body 1 and the coating equipment can be effectively solved. This design ensures that the gasket can provide stable positioning support during use, thereby improving the accuracy and consistency of coating size adjustment. The positioning between the gasket and the coating equipment can be achieved through the cooperation between the positioning pin and the positioning hole 3. Furthermore, the positioning between the gasket and the coating equipment can also be achieved by any other structural component that can achieve the above function, which will not be elaborated here. Compared with the prior art, the technical solution of this utility model, through the evenly distributed positioning holes 3, avoids the problem of inaccurate coating size adjustment caused by uneven distribution of the positioning holes 3, and improves the use effect and production efficiency of the gasket.
[0045] In some embodiments of this utility model, such as Figure 2 As shown, the adjusting piece 5 includes a main body 5c and a positioning part. The positioning part (not marked in the figure) cooperates with the positioning groove 5a, and the main body 5c is attached to the end face of the opening 7 of the gasket body 1.
[0046] Specifically, the positioning part is inserted into the positioning groove 5a, thereby fixing the main body 5c onto the second part 6. The depth of the positioning part inserted into the positioning groove 5a is adjustable, allowing the main body 5c connected to the positioning part to adjust the size of the opening 7. The shape of the main body 5c is the same as the shape of the end face of the second part 6 where the main body 5c is located. That is, the design of the main body 5c ensures the stability of the adjusting piece 5 during use. The cooperation between the positioning part and the positioning groove 5a allows the adjusting piece 5 to be adjusted in its installation position on the positioning groove 5a, thereby achieving precise adjustment of the coating size.
[0047] In a preferred embodiment, the main body 5c may be provided with adjusting teeth 5b with a fixed pitch, while the positioning groove 5a is provided with a groove with the same pitch as the adjusting teeth 5b. This design can further improve the accuracy and stability of the adjustment. Furthermore, the materials of the main body 5c and the positioning part can be selected to have good wear resistance and corrosion resistance to extend the service life of the adjusting piece 5.
[0048] Therefore, through the structural design of the main body 5c and the positioning part, a precise fit with the gasket body 1 is achieved, ensuring the stability of the adjusting piece 5 during use. The cooperation between the positioning part and the positioning groove 5a allows the adjusting piece 5 to adjust its installation position on the positioning groove 5a, thereby achieving precise adjustment of the coating size. This design effectively solves the positioning and fitting problem between the adjusting piece 5 and the gasket body 1, improving the accuracy and stability of coating size adjustment. Compared with the prior art, the technical solution of this utility model not only solves the problems of accuracy and stability in coating size adjustment, but also simplifies the adjustment process and reduces production costs through structural design.
[0049] In some embodiments of this utility model, the main body is a square plate structure, one end face of the positioning part is connected to the positioning part, and the connecting surface is parallel to the end face of the slot.
[0050] In other words, by setting the main body to a square structure with the same shape as the second part, the adjusting plate can adjust the coating size while making the coating edge regular, thereby improving the product yield and quality of the coating equipment.
[0051] In some embodiments of this utility model, such as Figure 1 As shown, the gasket body 1 is provided with a plurality of mounting holes 4, which are evenly distributed on the gasket body 1.
[0052] Specifically, after the gasket body 1 is positioned on the coating equipment via the positioning hole 3, it is installed and fixed on the coating equipment via the mounting hole 4. The mounting hole 4 can be configured in various ways. For example, holes can be drilled in the gasket body 1 by machining to ensure precise position and size. As a preferred embodiment, the diameter and spacing of the mounting holes 4 can be adjusted according to the specific needs of the coating device to ensure that the gasket can be securely installed on the coating device. Furthermore, the shape of the mounting hole 4 can also be designed as circular, square, or other shapes according to actual needs to adapt to different installation requirements.
[0053] Furthermore, the plurality of mounting holes 4 on the gasket body 1 are evenly distributed, allowing the gasket to be conveniently installed on the coating device through these mounting holes 4. For example, the gasket can be installed on the coating equipment using bolts. This design improves the adaptability and installation efficiency of the gasket on different coating devices, solving the problem of inconvenient installation of the gasket on the coating device. Compared with the prior art, the technical solution of this utility model significantly improves the ease of installation and adaptability of the gasket through the evenly distributed mounting holes 4, thereby effectively solving the technical problems in actual production.
[0054] In some embodiments of this utility model, a mounting component (not shown in the figure) is also included, which, in conjunction with the mounting hole 4, mounts the gasket onto the coating device.
[0055] The mounting components can take various forms, such as bolts, screws, or clips, depending on the structure and installation requirements of the coating apparatus. The mounting holes 4 can be designed as circular, square, or other shapes to accommodate different mounting components. Furthermore, the mounting holes 4 can be evenly distributed on the gasket body 1 to ensure the stability and balance of the gasket on the coating apparatus.
[0056] Specifically, the engagement of the mounting component with the mounting hole 4 allows the gasket to be fixed onto the coating device, thus solving the installation problem of the gasket on the coating device. This design ensures the stability and accuracy of the gasket during the coating process, improving the coating quality.
[0057] Therefore, by increasing the fit between the mounting component and the mounting hole 4, this invention not only solves the installation problem of the gasket on the coating device, but also improves the stability and coating quality of the coating process. Compared with the prior art, the gasket design of this invention is more flexible and can adapt to different coating devices and coating requirements, thereby improving production efficiency and product quality.
[0058] This utility model also provides a coating device, which includes the aforementioned shim for adjusting the coating size.
[0059] Specifically, the structural design of the gasket body 1 and the adjusting plate 5 allows the adjusting plate 5 to be adjusted in position on the positioning groove 5a, thereby achieving flexible adjustment of the coating size. The multiple positioning holes 3 and mounting holes 4 further improve the installation stability and adjustment accuracy of the gasket. The synergy of these technical features enables the coating equipment to adapt to coating requirements of different sizes and different slurries, solving the problems of inconvenient coating size adjustment, high cost, and poor adaptability.
[0060] The gasket body 1 is provided with a positioning groove 5a, and the adjusting piece 5 is installed on the positioning groove 5a and its installation position can be adjusted on the positioning groove 5a. In a preferred embodiment, the gasket body 1 includes a first part 2 and a second part 6, the second part 6 being located on opposite sides of the first part 2, and the positioning groove 5a being located at the end of the second part 6 away from the first part 2 and opposite to it. Further, the gasket body 1 is provided with a plurality of positioning holes 3, which are evenly distributed on the second part 6. The adjusting piece 5 includes a main body part 5c and a positioning part, the positioning part cooperating with the positioning groove 5a, and the main body part 5c fitting against the end face of the opening 7 of the gasket body 1. The positioning part is provided with adjusting teeth 5b with fixed pitch, and the positioning groove 5a is provided with a groove with the same pitch as the adjusting teeth 5b. The gasket body 1 is provided with a plurality of mounting holes 4, which are evenly distributed on the gasket body 1. It also includes the mounting component, which, in conjunction with the mounting hole 4, mounts the gasket onto the coating device.
[0061] Therefore, through the synergy of the aforementioned technical features, the coating equipment can achieve precise adjustment of the coating size, adapting to the coating requirements of different sizes and different slurries, thus solving the problems of inconvenient coating size adjustment, high cost, and poor adaptability. Compared with the prior art, the coating equipment of this utility model has higher adjustment accuracy and wider adaptability, effectively improving coating quality and production efficiency.
[0062] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof.
