Description

Technical Field

[0001] This utility model relates to the field of lithium battery coating, and in particular to a lithium battery coating surface density wide-range adjustment device. Background Technology

[0002] Lithium-ion batteries (hereinafter referred to as lithium batteries) have advantages such as high voltage, high energy density, high safety, and low self-discharge rate, making them a promising new energy source. With the further development of science and technology and the increasing prominence of energy and environmental issues, people have higher and higher requirements for lithium batteries. In applications such as electric vehicles, solar energy storage batteries, energy storage power stations, smartphones, and laptops, lithium batteries need to have high capacity, high rate capability, high stability, high safety, and high consistency. The key requirements of lithium batteries are closely related to the coating of the battery.

[0003] The existing slit coating machine, patent application number CN201920660044.5, has a plastic gasket positioned between the upper and lower lips. The plastic gasket has a U-shaped structure. When the slit coating machine coats the substrate, the thickness of the coating liquid sprayed onto the substrate depends on the height of the slit, which in turn depends on the thickness of the plastic gasket. Therefore, changing the plastic gasket to a different thickness can change the thickness of the coating on the substrate.

[0004] As mentioned above, in the prior art, since the shape of the gasket is fixed (such as a U-shaped structure), its width is also fixed, so the coating width cannot be adjusted. This limits the flexibility of the coating machine when different coating widths are required. Furthermore, the fixed gasket may not be able to fully adapt to substrates of different sizes or shapes, resulting in poor coating effect or waste of coating liquid. Utility Model Content

[0005] This invention provides a lithium battery coating density width adjustment device to solve the technical problem in the prior art where the gasket shape is fixed and the coating width cannot be adjusted.

[0007] Furthermore, the adjusting rod includes a transmission part, the outer wall of which is provided with an external thread, the stop block is provided with a transmission groove, and the inner wall of the transmission groove is provided with an internal thread that mates with the external thread.

[0008] Furthermore, the adjusting rod also includes a fixing part, which is fixedly connected to the transmission part. A rotating part is provided on the support plate, and the fixing part passes through the rotating part. The fixing part is rotatably mounted on the support plate through the rotating part.

[0009] Furthermore, the support plate and the mounting part are integrally formed.

[0010] Furthermore, a groove is provided on the top end face of the mounting part, and a slider is provided on the stop block, with the slider engaging with the groove.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0022] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0023] This utility model provides a lithium battery coating density width adjustment device, such as... Figures 1 to 2 As shown, the device includes a gasket body 1, which includes a mounting part 11. A width adjustment component 2 is provided on the mounting part 11. The width adjustment component 2 includes a support plate 21 and a stop block 22. The support part is fixedly connected to the mounting part 11, and the stop block 22 is slidably mounted on the mounting part 11. A rotatable adjustment rod 23 is mounted on the support plate 21. The adjustment rod 23 and the stop block 22 are linked and cooperated so that when the adjustment rod 23 rotates, it can drive the stop block 22 to slide along the mounting part 11.

[0024] In this embodiment, the adjusting rod 23 includes a transmission part 231, the outer wall of the transmission part 231 is provided with an external thread, the stop block 22 is provided with a transmission groove 221, and the inner wall of the transmission groove 221 is provided with an internal thread that mates with the external thread.

[0025] In this embodiment, the adjusting rod 23 further includes a fixing part 232, which is fixedly connected to the transmission part 231. A rotating member 211 is provided on the support plate 21, and the fixing part 232 passes through the rotating member 211. The fixing part 232 is rotatably mounted on the support plate 21 via the rotating member 211. In this embodiment, the rotating member 211 is a bearing.

[0026] In other embodiments, the rotation drive method of the fixing part 232 can be set to various forms such as manual rotation or motor-driven rotation.

[0027] In this embodiment, when it is necessary to adjust the width of the pad body 1, the operator will rotate the adjustment rod 23. The rotation of the adjustment rod 23 will cause the stop block 22 linked with it to slide on the mounting part 11. The sliding of the stop block 22 will change the effective width of the pad body 1, that is, the width of the contact with the material during coating. Since the coating surface density is related to the coating width and the amount of slurry supplied, the width of the pad body 1 can be adjusted to achieve a wide range of adjustment of the coating surface density.

[0028] In this embodiment, the support plate 21 and the mounting part 11 are integrally formed, which can effectively improve the strength and stability of the gasket body 1.

[0029] In this embodiment, a groove 111 is provided on the top end face of the mounting part 11, and a slider 222 is provided on the stop block 22. The slider 222 is engaged with the groove 111 to ensure that the stop block 22 can move along a predetermined path.

[0030] In this embodiment, the mounting part 11 includes a fixed section 112 and an extension section 113 extending in a direction away from the support plate 21. The slide groove 111 is located on the top end face of the fixed section 112 and the extension section 113. The extension section 113 can provide more sliding space for the stop block 22, thereby achieving a wider range of adjustment.

[0031] In this embodiment, the gasket body 1 further includes a spraying part 12, and the mounting part 11 and the width adjustment component 2 are each included in two sets. The two sets of mounting parts 11 are respectively located at both ends of the spraying part 12, and the two sets of width adjustment components 2 are arranged opposite to each other, so that the gasket body 1 has the ability to be fixed and adjusted at both ends, and can adapt to different application requirements.

[0032] It should be noted that the method of spraying slurry from the gasket body 1 to the coating area through the nozzle of the spraying part 12 is existing technology. Those skilled in the art should be clear about its structure, principle and usage, etc., and will not be described in detail here.

[0033] The present invention provides a lithium battery coating density width adjustment device, which can change the width of the gasket body 1 by adjusting the position of the stop 22 on the mounting part 11, thereby realizing the width adjustment of the lithium battery coating density to meet different production needs.
