Description

Technical Field

[0001] This utility model relates to the field of lithium battery production equipment, specifically to an electrode foreign matter cleaning device. Background Technology

[0002] During lithium battery production, electrodes are wound using a winding machine. During this process, various magnetic substances easily adhere to the electrode surface. These magnetic substances can react with battery materials inside the battery. If these magnetic substances are not removed promptly, they can severely affect the quality and performance of the lithium battery. Current technology typically uses magnetic rods to adsorb foreign matter from the electrode surface. However, after adsorption, the magnetic rods need to be manually cleaned. This is not only inefficient, failing to promptly remove magnetic foreign matter from the rod surface and reducing its continued adsorption capacity, but also ineffective in collecting magnetic foreign matter during cleaning, easily leading to secondary pollution. Utility Model Content

[0003] In order to overcome the defects in the prior art, this utility model provides a foreign matter cleaning device for electrode sheets, which can automatically clean magnetic rods and improve the cleaning efficiency of electrode sheets.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] This utility model discloses a foreign matter removal device for electrode sheets, comprising:

[0006] A dust hood, comprising a hood body, a dust outlet on the hood body, the dust outlet being able to communicate with an external dust collection device, the hood body having an inclined surface, an inlet on the inclined surface, and at least one magnetic rod at the inlet;

[0007] A scraper mechanism, comprising a scraper and a driving member, wherein the scraper contacts the surface of the magnetic rod, and the driving member is connected to the scraper to drive the scraper to move along the surface of the magnetic rod;

[0008] A connecting rail is provided, and the connecting rail is equipped with a fixing plate. The dust collection cover is movably connected to the connecting rail, so that the distance between the magnetic rod and the electrode is adjustable.

[0009] The above technical solution uses a scraper on the surface of the magnetic rod. After the magnetic rod adsorbs magnetic foreign objects on the surface of the electrode, the scraper can move back and forth on the surface of the magnetic rod to periodically and automatically clean the magnetic foreign objects on the surface of the magnetic rod, ensuring that the magnetic rod's adsorption capacity is not affected. Compared with traditional manual cleaning methods, this can effectively improve the cleaning efficiency of the magnetic rod and improve the safety performance of the battery. At the same time, the dust outlet on the dust hood can effectively clean the magnetic foreign objects that fall on the surface of the magnetic rod, preventing them from contaminating the working environment of the magnetic rod and re-adhering to the magnetic rod, thus improving the cleaning effect of the magnetic rod and the electrode.

[0010] Furthermore, it also includes a moving component, which includes: a limiting plate connected to the cover, a slider connected to the limiting plate on one side and to the connecting guide rail on the other side, and an adjusting screw located below the limiting plate and abutting against the limiting plate. The adjusting screw is connected to the fixed plate, and the position of the adjusting screw is adjustable.

[0011] The connecting rail is used to fix the electrode foreign object cleaning device to other components, and the movable component is used to adjust the position of the dust suction hood, so as to flexibly adjust the distance between the magnetic rod and the electrode surface to adapt to different production needs and electrode specifications, and ensure the best adsorption effect.

[0012] Furthermore, the fixed plate is provided with a screw hole, and the adjusting screw passes through the screw hole. By adjusting the position of the adjusting screw passing through the screw hole, the height of the adjusting screw against the limiting plate can be adjusted, thereby adjusting the position of the dust collection hood.

[0013] Furthermore, the scraper includes a first movable block and a second movable block connected to the first movable block. The first movable block extends along a first direction, and the second movable block has a through hole. The second movable block is fitted onto the magnetic rod through the through hole. The driving member is connected to the first movable block, driving the first movable block to move along a second direction and causing the second movable block to move. The shape and size of the through hole are set according to the shape and size of the magnetic rod; it cannot be too large or too small. If it is too large, it will not be able to clean the magnetic foreign matter on the magnetic rod; if it is too small, it will not be able to fit onto the magnetic rod.

[0014] Furthermore, the driving component includes a cylinder, which is connected to the cover and disposed on the outside of the cover.

[0015] Furthermore, the inclined surface is provided with partitions, which are spaced apart to form the inlet, and there is a preset gap between the partitions and the magnetic rod. The preset gap is used to allow magnetic foreign objects scraped off by the scraper to pass through, and the preset gap does not need to be too large.

[0016] Furthermore, the inclined surface is provided with multiple inlets, each inlet having at least one magnetic rod, the magnetic force of which is adjustable. The magnetic rod is an electromagnetic rod, and the magnetic force can be adjusted by changing the current, thereby improving the stability and adaptability of the magnetic rod during adsorption.

[0017] Furthermore, the dust outlet is located at the bottom of the cover. This location allows magnetic debris removed by the scraper to be more easily collected by external vacuum equipment, preventing secondary pollution.

[0018] Furthermore, the enclosure is provided with an observation window. The observation window is used to observe whether magnetic foreign objects inside the enclosure are cleaned and collected in a timely manner.

[0019] Furthermore, a connecting pipe is provided at the dust outlet, one end of which is connected to the dust outlet, and the other end can be connected to an external vacuuming device.

[0020] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0021] 1. This application provides a scraper on the surface of the magnetic rod. After the magnetic rod adsorbs magnetic foreign objects on the surface of the electrode, the scraper can reciprocate on the surface of the magnetic rod to periodically and automatically clean the magnetic foreign objects on the surface of the magnetic rod, ensuring that the magnetic rod's adsorption capacity is not affected. Compared with traditional manual cleaning methods, this can effectively improve the cleaning efficiency of the magnetic rod and improve the safety performance of the battery. At the same time, the dust outlet on the dust hood can effectively clean the magnetic foreign objects that fall on the surface of the magnetic rod, preventing them from contaminating the working environment of the magnetic rod and re-attaching to the magnetic rod, thus improving the cleaning effect of the magnetic rod and the electrode.

[0022] 2. This application adjusts the position of the dust collection hood by setting a movable component, which can flexibly adjust the distance between the magnetic rod and the electrode surface to adapt to different production needs and electrode specifications, thereby improving the stability and adaptability of the adsorption effect and ensuring the best adsorption effect.

[0033] Reference Figures 1-4 This application provides an electrode foreign matter cleaning device, comprising:

[0034] A dust collection hood includes a hood body 1, the interior of which is hollow, and a dust outlet on the hood body 1. The dust outlet can be connected to an external vacuum cleaner. The external vacuum cleaner is equipped with a fan speed when vacuuming, so as to effectively collect magnetic foreign objects that fall inside the hood body 1.

[0035] In the embodiments of this application, the dust outlet is located at the bottom of the cover 1, and a connecting pipe 12 is provided at the dust outlet. One end of the connecting pipe 12 is connected to the dust outlet, and the other end can be connected to an external vacuuming device.

[0036] In one possible embodiment, the cover 1 and the connecting tube 12 are integrally formed.

[0037] like Figure 1 , Figure 2 and Figure 4 As shown, the cover 1 has an inclined surface. In use, the inclined surface is parallel to the electrode plate, thereby ensuring that magnetic foreign objects on the surface of the electrode plate can be effectively adsorbed. An inlet is provided on the inclined surface, and at least one magnetic rod 2 is provided at the inlet. When adsorbing magnetic foreign objects on the electrode plate, there is a preset distance between the magnetic rod 2 and the electrode plate. The preset distance can be flexibly set, as long as it can ensure that the magnetic rod 2 adsorbs the magnetic foreign objects. The shape and size of the cover 1 can be flexibly set, as long as the inclined surface where the magnetic rod 2 is located is parallel to the electrode plate.

[0038] Magnetic rod 2 is an electromagnetic rod. Generally, a magnetic rod is a long, rod-shaped structure. Its length and size can be set according to the size of the cover 1, and the shape of its cross-section can also be flexibly set, such as... Figure 1 and Figure 2 As shown in the embodiment of this application, the magnetic rod 2 has a rectangular cross-section and is fixed to the cover 1 through its central axis.

[0039] Optionally, a partition 3 is provided on the inclined surface, and any two partitions 3 are spaced apart to form an inlet. There is a preset gap between the partition 3 and the magnetic rod 2. The size of the gap can be flexibly set, as long as it can ensure that the magnetic foreign objects can be scraped off into the inside of the cover 1.

[0040] The inclined surface may be provided with multiple inlets, and each inlet may be provided with at least one magnetic rod 2, and the magnetic force of at least one magnetic rod 2 is adjustable.

[0041] like Figure 1 and Figure 2 As shown, in the embodiments of this application, three inlets are arranged parallel to and spaced apart along the inclined plane, and each inlet is provided with a magnetic rod 2.

[0042] Optionally, observation windows 11 are provided on both sides of the cover 1 to facilitate the confirmation of the cleaning status of magnetic foreign objects inside the cover 1.

[0043] The scraper mechanism includes a scraper 4 and a driving member. The scraper 4 is in contact with the surface of the magnetic rod 2. The driving member is connected to the scraper 4 and drives the scraper 4 to move along the surface of the magnetic rod 2.

[0044] Optionally, the driving component is a cylinder 5, which is connected to the cover 1 and located on the outside of the cover 1.

[0045] like Figure 2 and Figure 3 As shown in the embodiment of this application, the scraper 4 includes a first moving block 401 and a second moving block 402 connected to the first moving block 401. The first moving block 401 extends along a first direction, and the second moving block 402 has a through hole. The second moving block 402 is sleeved on the magnetic rod 2 through the through hole. The cylinder 5 is connected to the first moving block 401, driving the first moving block 401 to move repeatedly along a second direction, and driving the second moving block 402 to move repeatedly along the surface of the magnetic rod 2, so as to automatically clean magnetic foreign objects on the magnetic rod 2. The first direction is perpendicular to the magnetic rod 2, and the second direction is parallel to the magnetic rod 2.

[0046] The number of second moving blocks 402 is flexibly set according to the number of magnetic rods 2, and the shape and size of the through holes on the second moving blocks 402 are flexibly set according to the shape and size of the magnetic rods 2, such as... Figure 3 As shown, when multiple magnetic rods 2 are provided, multiple second moving blocks 402 are arranged at intervals on the first moving block 401 along the first direction, and the interval distance is flexibly set according to the distance between the magnetic rods.

[0047] A connecting rail 6 is provided, on which a fixing plate 10 is provided. The dust collection cover is movably connected to the connecting rail 6, making the distance between the magnetic rod 2 and the surface of the electrode adjustable. The connecting rail 6 and the fixing plate 10 are used to fix the dust collection cover to other components. The connecting rail 6 and the fixing plate 10 may or may not be connected.

[0048] like Figure 4 As shown, in order to adjust the position of the dust collection hood, the electrode foreign object cleaning device also includes a moving component. The moving component includes: a limiting plate 7 connected to the hood 1, a slider 8 connected to the limiting plate 7 on one side and to the connecting guide rail 6 on the other side, an adjusting screw 9 located below the limiting plate 7 and in contact with the limiting plate 7, and the adjusting screw 9 connected to the fixing plate 10. By adjusting the position of the adjusting screw 9 connected to the fixing plate 10, the distance between the magnetic rod 2 and the electrode surface can be adjusted to improve the stability and adaptability of the magnetic rod 2's adsorption effect.

[0049] In the embodiments of this application, the fixing plate 10 is provided with a screw hole, and the adjusting screw 9 passes through the screw hole so that the position of the adjusting screw 9 on the fixing plate 10 is adjustable.

[0050] In use, the connecting guide rail 6 and the fixing plate 10 are installed in the preset position of the winding machine, so that the inclined surface of the cover 1 is parallel to the electrode sheet, and multiple magnetic rods 2 are aligned with the surface of the electrode sheet. According to the specifications of the electrode sheet and the production process requirements, the distance between the multiple magnetic rods 2 and the surface of the electrode sheet is adjusted by adjusting the screw 9 until the preset distance is reached. When the winding machine is working, the multiple magnetic rods 2 continuously adsorb magnetic foreign objects on the surface of the electrode sheet. The scraper on the magnetic rod 2 cleans the surface of the magnetic rod 2 at preset time intervals. The cleaned magnetic foreign objects fall into the inside of the cover 1 and are collected by the external dust collection equipment through the dust outlet.

[0051] The cleaning device in this embodiment can flexibly adjust the distance between the magnetic rod and the electrode surface to adapt to different production needs and electrode specifications, thereby improving the stability and adaptability of the adsorption effect and ensuring the best adsorption effect. Furthermore, by setting a scraper on the surface of the magnetic rod, after the magnetic rod adsorbs magnetic foreign objects from the electrode surface, the scraper can reciprocate on the surface of the magnetic rod to periodically and automatically clean the magnetic foreign objects, ensuring that the adsorption capacity of the magnetic rod is not affected. Compared with traditional manual cleaning methods, this effectively improves the cleaning efficiency of the magnetic rod and enhances the safety performance of the battery. Simultaneously, the dust outlet on the dust hood effectively cleans magnetic foreign objects that fall onto the surface of the magnetic rod, preventing them from contaminating the working environment of the magnetic rod and re-attaching to the magnetic rod, thus improving the cleaning effect on both the magnetic rod and the electrode.

[0052] This utility model uses specific embodiments to illustrate the principle and implementation of the utility model. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​the utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the utility model. Therefore, the content of this specification should not be construed as a limitation of the utility model.
