Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a tab cleaning device and a coating machine. Background Technology

[0002] Lithium-ion batteries have gradually become the mainstream power batteries due to their advantages such as high energy density and small size. The electrode is one of the important components of a lithium-ion battery. In the electrode production process, a crucial step is coating the current collector surface with a slurry, which is typically accomplished using a transfer coating machine. The transfer coating machine uses the rotation of coating rollers to move the slurry, and adjusts the slurry transfer amount by adjusting the doctor blade gap. The slurry is transferred to the substrate using the rotation of the back roller or coating roller, thus achieving uniform coating of the electrode substrate. After coating, the slurry on the substrate needs to be heated and dried to remove the solvent and allow the solid material to adhere firmly to the current collector surface.

[0003] However, existing transfer coating technology has some drawbacks. For example, the installation of the baffle in existing transfer coating machines usually relies on manual operation, which is subject to certain errors. If the baffle foam or scraper is not installed tightly, the slurry can easily overflow from the trough and contaminate the non-coated area on the outer periphery of the coating roller. As the coating roller rotates, the slurry in these non-coated areas may transfer to the tab welding area on the current collector, causing material leakage on both sides of the tab, affecting the quality of subsequent tab welding, and thus affecting the reliability of the battery's electrical connection.

[0038] To address the issue of material leakage on both sides of the electrode tab in related technologies, which affects the subsequent electrode tab welding quality, the first aspect is to refer to... Figure 1 , Figure 2 and Figure 3 , Figure 1 A schematic diagram of the electrode cleaning device in one embodiment of this application is shown. Figure 2 A front view of an electrode cleaning device according to an embodiment of this application is shown. Figure 3 This illustration shows a side view of an electrode cleaning device according to an embodiment of this application. An embodiment of this application provides an electrode cleaning device applied to a coating machine and disposed on one side of the coating machine. The coating machine includes a coating frame 20 and a coating roller 30. The electrode cleaning device includes: a fixing component 100 disposed on one side of the coating machine; the fixing component 100 is fixedly connected to a worktable for fixing the electrode cleaning device to the worktable; a cleaning component 300 disposed at a relative position to the coating roller 30 for cleaning the electrode area; and an adjusting component 200 connecting the fixing component 100 and the cleaning component 300 for adjusting the position of the cleaning component 300 relative to the coating roller 30. This application provides an electrode cleaning device capable of wiping and cleaning the electrode area to ensure the smooth progress of subsequent manufacturing processes.

[0039] For example, the tab cleaning device is applied to a coating machine and installed on both sides of the coating machine to clean the tab area and prevent the slurry from contaminating the tab area, thereby affecting the quality of subsequent tab welding. The coating machine includes a coating frame 20 and a coating roller 30. The tab cleaning device includes a fixing component 100, an adjusting component 200, and a cleaning component 300. The two sets of fixing components 100, the two sets of adjusting components 200, and the two sets of cleaning components 300 are symmetrically arranged on both sides of the coating machine, that is, a set of tab cleaning devices is set on each side of the coating machine to ensure the cleaning effect on the tab area.

[0040] The fixing component 100 is installed on one side of the coating machine and fixedly connected to the worktable to provide stable support, thus securing the entire tab cleaning device to the worktable and ensuring its stability. The adjusting component 200 is connected between the fixing component 100 and the cleaning component 300, used to adjust the position of the cleaning component 300 relative to the coating roller 30, allowing the tab cleaning device to adapt to different specifications of electrode sheets. Optionally, the adjusting component 200 includes a first adjusting member 202, a second adjusting member 204, and a third adjusting member 206. These adjusting members work together to ensure that the cleaning component 300 contacts the tab area at a suitable position, ensuring cleaning effectiveness while avoiding interference with the normal coating area. The cleaning component 300 is positioned near the coating roller 30, directly cleaning the tab area. The position of the cleaning component 300 is adjusted by the adjusting component 200 to ensure effective contact with the tab area, removing slurry contamination from uncoated areas, improving the cleanliness of the tab welding area, and ensuring subsequent welding quality.

[0041] In this embodiment, two sets of electrode cleaning devices are symmetrically arranged on the left and right sides, respectively located at both ends of the coating machine. These electrode cleaning devices can precisely adjust the position of the cleaning component 300 via the adjusting component 200, ensuring that the cleaning cloth 304 accurately acts on the electrode area, effectively removing slurry contamination from the electrode area. This improves the processing quality of the electrode sheet, ensures the cleanliness of the electrode welding area, and enhances the welding quality and consistency of the battery. Simultaneously, the adjusting component 200 allows the electrode cleaning device to adapt to different specifications of current collectors and electrodes, improving the flexibility and adaptability of the electrode cleaning device.

[0042] In an exemplary embodiment, the fixing component 100 includes: a first fixing block 102 disposed at the bottom of the tab cleaning device and fixedly connected to the workbench; and a second fixing block 104 disposed above the first fixing block 102 and connected to the first fixing block 102 via an adjusting component 200.

[0043] For example, the fixing component 100 is used to securely mount the tab cleaning device on the workbench and provide support to ensure the stability of the cleaning process. The fixing component 100 includes a first fixing block 102 and a second fixing block 104, which are arranged vertically. Optionally, the first fixing block 102 is located at the bottom of the tab cleaning device, and its first end can be fixedly connected to the workbench by fasteners, so that the tab cleaning device can be firmly fixed to one side of the coating machine to prevent shaking or positional displacement during the cleaning process. The second fixing block 104 is located above the first fixing block 102, and its second end is connected to the second end of the first fixing block 102 via an adjusting component 200. The adjusting component 200 can adjust the relative distance between the first fixing block 102 and the second fixing block 104.

[0044] The first fixing block 102 is fixedly connected to the workbench by bolts; the second fixing block 104 is slidably connected to the first fixing block 102 by the first adjusting member 202; the distance between the second fixing block 104 and the first fixing block 102 can be adjusted in the first direction (i.e., the length direction of the coating roller 30) by the first adjusting member 202.

[0045] In this embodiment, the fixing component 100 can ensure that the cleaning component 300 and the adjusting component 200 have good stability during operation; and the two sets of fixing components 100 are symmetrically arranged on both sides of the coating machine, so that the entire tab cleaning device can act on both sides of the coating machine at the same time, ensuring the cleaning effect of the tab area, improving the processing quality of the electrode sheet and the reliability of the subsequent welding process.

[0046] The adjustment assembly 200 of the tab cleaning device is mainly used to adjust the position of the cleaning assembly 300 in multiple directions to ensure that the cleaning assembly 300 can adapt to the cleaning needs of coating rollers 30 of different specifications and tab areas. In an exemplary embodiment, the adjustment assembly 200 includes a first adjustment member 202, a second adjustment member 204, and a third adjustment member 206. The first adjustment member 202, the second adjustment member 204, and the third adjustment member 206 cooperate with each other to achieve adjustment in three dimensions.

[0047] The first adjusting member 202 is parallel to the coating roller 30 and extends along the length of the coating roller 30, passing through the first fixing block 102 and the second fixing block 104. Optionally, the first end of the first adjusting member 202 perpendicularly passes through the first fixing block 102 and is fixedly connected to the first fixing block 102; the second end of the first adjusting member 202 perpendicularly passes through the first end of the second fixing block 104; the first adjusting member 202 is used to adjust the distance between the first fixing block 102 and the second fixing block 104 in a first direction. The first adjusting member 202 allows the second fixing block 104 to move along the first direction under the guidance of the first adjusting member 202, thereby adjusting the position of the cleaning assembly 300 in the first direction; wherein, the first direction refers to the length direction of the coating roller 30, i.e. Figure 1 and Figure 2 The X-direction of the coordinate system. The design of the first adjustment element 202 can control the coverage range of the tab cleaning device in the X-direction to match the tabs of different widths, ensuring that the cleaning assembly 300 can cover all parts that need to be cleaned.

[0048] The second adjusting member 204 penetrates vertically through the second fixing block 104 and is perpendicular to the first adjusting member 202. The first end of the second adjusting member 204 penetrates vertically through the second end of the second fixing block 104, and the second end of the second adjusting member 204 is connected to the third adjusting member 206, used to adjust the distance between the third adjusting member 206 and the second fixing block 104 in a second direction. The second direction refers to... Figure 1 In the Y direction of the coordinate system, the function of the second adjusting member 204 is to adjust the position of the third adjusting member 206 in the Y direction, thereby changing the front-to-back distance of the cleaning component 300 (i.e., its position in the Y direction) to ensure that the cleaning component 300 can fit tightly against the coating roller 30, achieving a stable and efficient cleaning effect.

[0049] The third adjusting member 206 is connected to the second adjusting member 204 and is fixedly connected to the cleaning assembly 300. The first end of the third adjusting member 206 vertically penetrates the second end of the second adjusting member 204, and the second end of the third adjusting member 206 is fixedly connected to the cleaning assembly 300. It is used to adjust the distance between the cleaning assembly 300 and the workbench in a third direction. Here, the third direction refers to… Figure 1 and Figure 2 In the Z-direction of the coordinate system, the third adjusting member 206 adjusts the position of the cleaning component 300 in the Z-direction, that is, adjusts the height of the cleaning component 300 to ensure that the cleaning component 300 can effectively contact the tab area. In addition, the third adjusting member 206 can work with the first adjusting member 202 and the second adjusting member 204 to fine-tune the position of the cleaning component 300 to adapt to different specifications of battery tabs, so that the cleaning component 300 can meet different cleaning needs.

[0050] In this embodiment, the adjustment component 200 forms a precise three-dimensional adjustment structure through three mutually perpendicular adjustment members, allowing the cleaning component 300 to be freely adjusted in the first, second, and third directions. Specifically, the first adjustment member 202 controls the position of the second fixed block 104 in the X direction, while the second adjustment member 204 affects the overall front-to-back distance (i.e., position in the Y direction) of the cleaning component 300 by adjusting the position of the third adjustment member 206 in the Y direction. The third adjustment member 206 further adjusts the height of the cleaning component 300 (i.e., position in the Z direction), enabling the cleaning component 300 to be kept in the optimal cleaning position, improving the stability of the cleaning effect, and reducing product defects caused by inadequate cleaning. Furthermore, the adjustment component 200 allows the tab cleaning device to adapt to different specifications of coating machines and tab areas, improving the flexibility and cleaning effect of the tab cleaning device, and enhancing the quality of electrode processing and the reliability of subsequent welding processes.

[0051] In an exemplary embodiment, the cleaning assembly 300 includes: a cleaning seat 302, which is fixedly connected to a third adjusting member 206; the cleaning seat 302 is used to support a cleaning cloth 304; and the cleaning cloth 304 is detachably fixed to the side of the cleaning seat 302 near the coating roller 30.

[0052] For example, the cleaning component 300 is used to efficiently clean the tab area to reduce the impact of slurry contamination on subsequent processes. The cleaning component 300 includes a cleaning seat 302 and a cleaning cloth 304, which work together to achieve precise wiping of the tab area.

[0053] The cleaning assembly 300 includes a cleaning seat 302 and a cleaning cloth 304. The cleaning seat 302 is fixed to the second end of the third adjusting member 206 and can be fixedly connected to the adjusting assembly 200 via the third adjusting member 206, so that the cleaning seat 302 can move synchronously with the adjusting assembly 200 to adapt to the position requirements of different specifications of coating machines and tab areas. The cleaning seat 302 is a rectangular block, and the cleaning cloth 304 is provided on the side of the cleaning seat 302 near the coating roller 30.

[0054] The cleaning cloth 304 is detachably fixed to the cleaning seat 302 near the coating roller 30 using adhesive tape. This cleaning cloth 304 is made of lint-free cloth, effectively removing residual slurry in the tab area during coating and reducing the impact of impurities on subsequent tab welding. Furthermore, the detachable fixation of the cleaning cloth 304 to the cleaning seat 302 allows operators to easily and quickly replace it without disassembling the entire cleaning assembly 300, reducing maintenance costs and improving ease of use and maintenance efficiency. The lint-free cloth 304 is typically made of polyester or polyamide microfiber, combined with laser sealing technology to ensure no fiber residue during wiping. Its three-dimensional mesh structure provides strong liquid absorption and quickly traps contaminants, preventing secondary contamination. The lint-free cloth can be moistened with alcohol or other cleaning agents, depending on actual production needs and equipment specifications, further enhancing its cleaning effect.

[0055] In this embodiment, the cleaning seat 302 is fixedly connected to the third adjusting member 206, allowing the cleaning seat 302 to move synchronously with the adjusting component 200, thereby adapting to the positional requirements of different specifications of coating machines and tab areas. The cleaning cloth 304 is detachably fixed to the cleaning seat 302 with adhesive tape, facilitating maintenance and replacement of the cleaning cloth 304 and improving the ease of use and maintenance efficiency of the equipment. Simultaneously, the cleaning cloth 304 is made of alcohol-moistened lint-free cloth, which can effectively remove residual slurry in the tab area during the coating process and reduce the impact of impurities on subsequent tab welding.

[0056] Secondly, this application provides a coating machine, including any of the tab cleaning devices provided in the first aspect, the tab cleaning device being disposed on one side of the coating machine; the coating machine also includes a coating frame 20 and a coating roller 30, the coating roller 30 being rotatably connected to the coating frame 20.

[0057] For example, the coating machine integrates a tab cleaning device from the first aspect to ensure the tab area remains clean, thereby improving the quality of subsequent tab welding. The coating machine mainly includes a coating frame 20, a coating roller 30, and a tab cleaning device, with the coating roller 30 rotatably connected to the coating frame 20. The tab cleaning device is located on one side of the coating machine, and its main function is to remove the slurry from the tab area, preventing contamination from affecting subsequent processes, especially welding. The tab cleaning device adopts an adjustable structural design, including an adjustment component 200 and a cleaning component 300, which can adapt to different specifications of coating machines and tab sizes, thereby ensuring that the cleaning cloth 304 can accurately clean the tab area, achieving efficient cleaning. Furthermore, the tab cleaning device can be independently installed on one side of the coating machine without affecting its normal operation, and is easy to maintain and replace, improving the cleaning performance and production efficiency of the equipment.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
