Description

Technical Field

[0001] This utility model relates to the field of lithium-ion battery manufacturing technology, and in particular to a chip removal device. Background Technology

[0002] Lithium-ion battery electrode slurry coating involves uniformly coating the positive and negative electrode sheets with a slurry that has good stability, viscosity, and flowability. Since some metal particles inevitably exist in the electrode slurry, if the metal particles are large, it is necessary to insert a permanent magnet rod into the bottle containing the electrode slurry and stir to adsorb the metal particles in the electrode slurry.

[0003] Understandably, the metal particles adsorbed on the surface of the permanent magnet rod need to be cleaned before reuse. However, due to the strong adsorption effect of the permanent magnet rod on metal particles, the metal particles are difficult to remove from the surface. Operators need to hold the permanent magnet rod and use a cleaning ring to slowly scrape them off, which is labor-intensive and inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a chip removal device that avoids the excessive effort required by operators when cleaning metal particles from permanent magnet rods by hand, thus saving manpower and improving the efficiency and effectiveness of cleaning permanent magnet rods.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A chip removal device for removing metal particles from the surface of a permanent magnet rod, wherein one end of the permanent magnet rod is a handheld end, and the surface of the handheld end is not adsorbed with the metal particles, comprising:

[0007] The base has a fixing groove, and the handheld end can be inserted into the fixing groove;

[0008] A cleaning ring, which can be fitted onto the permanent magnet rod and scrape off the metal particles on the surface of the permanent magnet rod;

[0009] A connecting assembly that connects the base and the cleaning ring, such that the cleaning ring moves closer to or further away from the base along the axial direction of the permanent magnet rod.

[0010] As an optional solution for the above-mentioned chip removal device, the connecting assembly includes a connecting frame, which is fixedly connected to the base, and the cleaning ring is slidably disposed on the connecting frame.

[0011] As an alternative to the aforementioned chip removal device, the connecting assembly further includes an elastic element disposed on the connecting frame, the elastic element being configured to drive the cleaning ring closer to the base.

[0012] As an optional solution to the above-mentioned chip removal device, the connecting assembly further includes a snap-fit ​​component, which is retractably mounted on the connecting frame to snap the cleaning ring.

[0013] As an optional solution for the above-mentioned chip removal device, when the snap-fit ​​component snaps into the cleaning ring, the distance between the cleaning ring and the base is greater than the length of the permanent magnet.

[0014] As an optional solution to the above-mentioned chip removal device, the base has a first inclined surface, the opening of the fixing groove is opened on the first inclined surface, and the first inclined surface is inclined away from the cleaning ring along the direction away from the opening of the fixing groove.

[0015] As an optional solution to the above-mentioned chip removal device, the chip removal device further includes a collection box, and the base is disposed in the collection box.

[0016] As an optional solution for the above-mentioned chip removal device, the cleaning ring is provided with a gathering groove on the side facing the base, and the gathering groove has a second inclined surface. The second inclined surface is arranged around the permanent magnet rod and is inclined in a direction away from the permanent magnet rod, and in a direction away from the base.

[0017] As an alternative to the above-mentioned chip removal device, the gathering groove has a third inclined surface, which surrounds and connects to the second inclined surface, and is inclined in a direction away from the permanent magnet rod, while the second inclined surface is inclined in a direction closer to the base.

[0018] As an alternative to the aforementioned chip removal device, the outer surface of the cleaning ring has an antimagnetic layer made of a non-magnetic material.

[0019] The beneficial effects of this utility model are:

[0020] This invention provides a chip removal device. In this device, the handheld end of a permanent magnet rod is positioned within a fixed groove in the base. The operator can then control a cleaning ring to be fitted onto the permanent magnet rod through its other end, causing the permanent magnet rod to move along the connecting assembly. This allows the cleaning ring to scrape off metal debris from the surface of the permanent magnet rod. The handheld end of the permanent magnet rod does not attract metal debris; therefore, inserting the handheld end into the fixed groove of the base not only secures the permanent magnet rod to the base but also ensures that the cleaning ring can effectively clean it.

[0021] This chip removal device can fix the permanent magnet rod with a base, avoiding the need for operators to hold the rod by hand, which would be too strenuous when cleaning the metal particles on the permanent magnet rod. This saves manpower and improves the efficiency and effectiveness of cleaning the permanent magnet rod. Attached Figure Description

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] Lithium-ion battery electrode slurry coating involves uniformly coating the positive and negative electrode sheets with a slurry that has good stability, viscosity, and flowability. Since some metal particles inevitably exist in the electrode slurry, if the metal particles are large, it is necessary to insert a permanent magnet rod into the bottle containing the electrode slurry and stir to adsorb the metal particles in the electrode slurry.

[0039] like Figure 1 As shown, for ease of use by operators, one end of the permanent magnet rod 100 is a handheld end 101. Operators insert the permanent magnet rod 100 into the bottle through the handheld end 101, so the surface of the handheld end 101 will not attract metal particles.

[0040] Understandably, before the permanent magnet rod 100 can be reused, the metal particles adsorbed on its surface need to be cleaned. However, due to the adsorption effect of the permanent magnet rod 100 on the metal particles, it is difficult to remove the metal particles from its surface. Operators need to hold the permanent magnet rod 100 and use the cleaning ring 2 to slowly scrape them off, which is labor-intensive and inefficient.

[0041] To address the aforementioned problems, this embodiment provides a chip removal device for removing metal particles from the surface of the permanent magnet rod 100. For example... Figures 1-3As shown, the chip removal device includes a base 1, a cleaning ring 2, and a connecting assembly 3. The base 1 is provided with a fixing groove 11, and the handheld end 101 can be inserted into the fixing groove 11. The cleaning ring 2 can be fitted onto the permanent magnet rod 100 and scrape off the metal particles on the surface of the permanent magnet rod 100. The connecting assembly 3 connects the base 1 and the cleaning ring 2 so that the cleaning ring 2 moves closer to or away from the base 1 along the axial direction of the permanent magnet rod 100.

[0042] In this chip removal device, since the surface of the handheld end 101 of the permanent magnet rod 100 is free of metal particles, the handheld end 101 can be placed in the fixing groove 11 of the base 1. Then, the operator can control the cleaning ring 2 to be fitted onto the permanent magnet rod 100 through the other end, and move the permanent magnet rod 100 along the connecting assembly 3, thereby allowing the cleaning ring 2 to scrape off the metal debris from the surface of the permanent magnet rod 100. The handheld end 101 of the permanent magnet rod 100 does not attract metal debris; therefore, inserting the handheld end 101 into the fixing groove 11 of the base 1 not only secures the permanent magnet rod 100 to the base 1, but also ensures that the cleaning ring 2 can clean the permanent magnet rod 100 thoroughly.

[0043] The chip removal device can fix the permanent magnet rod 100 through the base 1, avoiding the need for operators to hold it by hand and thus avoid excessive effort when cleaning the metal particles of the permanent magnet rod 100, saving manpower and improving the efficiency and effect of cleaning the permanent magnet rod 100.

[0044] In this embodiment, the chip removal device also includes a collection box 4, and the base 1 is disposed inside the collection box 4. The collection box 4 can serve as the chassis of the chip removal device to be stably placed on the table, so that the operator does not need to hold the chip removal device with one hand to perform chip removal on the permanent magnet rod 100, making it convenient for the operator to use. It can also collect the metal particles scraped off by the cleaning ring 2.

[0045] Preferably, the base 1 has a first inclined surface 12, and the opening of the fixing groove 11 is formed on the first inclined surface 12. Along the direction away from the opening of the fixing groove 11, the first inclined surface 12 is inclined away from the cleaning ring 2. When the metal particles are scraped off by the cleaning ring 2, they will slide down along the first inclined surface 12 and move away from the permanent magnet 100, effectively preventing the metal particles from being re-attracted by the permanent magnet 100.

[0046] In this embodiment, the connecting component 3 includes a connecting frame 31, which is fixedly connected to the base 1, and the cleaning ring 2 is slidably disposed on the connecting frame 31. The connecting frame 31 connects the cleaning ring 2 and the base 1 to form an integral module, which facilitates the operator to use the chip removal device to remove chips from the permanent magnet rod 100. It also makes the chip removal device easy to store, preventing the cleaning ring 2 or the base 1 from being lost.

[0047] like Figures 1-4As shown, the connecting frame 31 has a sliding groove 311, the axis of which is parallel to the axis of the permanent magnet rod 100. The cleaning ring 2 is connected to a sliding member 24, which is slidably disposed within the sliding groove 311. The sliding groove 311 guides the cleaning ring 2, ensuring that its direction of movement does not change. This guarantees that the cleaning ring 2 can be accurately fitted onto the outer surface of the permanent magnet rod 100 and move along the axis of the permanent magnet rod 100, thereby cleaning the metal particles on the surface of the permanent magnet rod 100.

[0048] Preferably, the sliding member 24 is also connected to a limiting part 25. The sliding member 24 passes through the connecting frame 31, and the limiting part 25 and the cleaning ring 2 are located on opposite sides of the connecting frame 31, with both the limiting part 25 and the cleaning ring 2 slidingly abutting against the connecting member. This structure ensures that the cleaning ring 2 can only slide along the axial direction of the slide groove 311 without rotating or shifting, thus ensuring relative stability between the cleaning ring 2 and the permanent magnet rod 100. This ensures that the gap between the cleaning ring 2 and the permanent magnet rod 100 does not change, and when the operator moves the cleaning ring 2, the resistance experienced by the cleaning ring 2 will not change due to the change in the size of the gap with the permanent magnet rod 100, making it convenient for the user.

[0049] In this embodiment, the connecting component 3 further includes an elastic element 32, which is disposed on the connecting frame 31 and configured to drive the cleaning ring 2 close to the base 1. That is, when the operator installs the permanent magnet rod 100 on the base 1, the elastic element 32 can provide a force to the cleaning ring 2 to clean the surface of the permanent magnet rod 100, thereby reducing the force required for the operator to drive the cleaning ring 2, reducing the operator's workload, and improving efficiency.

[0050] like Figures 1-3 As shown, the connecting assembly 3 also includes a guide post 34, which passes through the cleaning ring 2. The guide post 34, together with the slide groove 311, guides the cleaning ring 2, preventing the cleaning ring 2 from deflecting and getting stuck in the slide groove 311. In addition, the elastic element 32 is sleeved on the guide post 34, which ensures that the elastic element 32 will not bend when compressed by the cleaning ring 2.

[0051] Preferably, the connecting assembly 3 further includes a snap-fit ​​member 33, which is telescopically mounted on the connecting frame 31 to snap the cleaning ring 2. The operator can use the snap-fit ​​member 33 to snap the cleaning ring 2 onto the compressed elastic element 32, while ensuring that the cleaning ring 2 does not move, so that the operator can smoothly insert the handheld end 101 of the permanent magnet rod 100 into the fixing groove 11 of the base 1, and then release the snap-fit ​​member 33, so that the cleaning ring 2 can be used to clean the metal particles on the surface of the permanent magnet rod 100.

[0052] like Figure 1As shown, when the snap-fit ​​33 snaps into the cleaning ring 2, the distance between the cleaning ring 2 and the base 1 is greater than the length of the permanent magnet rod 100. When the operator inserts the permanent magnet rod 100 into the fixing groove 11 of the base 1, the cleaning ring 2 and the permanent magnet rod 100 are coaxially arranged and spaced apart. At this time, it is only necessary to loosen the snap-fit ​​33, and the cleaning ring 2 can be sleeved on the permanent magnet rod 100 under the drive of the elastic member 32 to complete the cleaning of the metal particles on the surface of the permanent magnet rod 100.

[0053] like Figure 5 As shown, the front end of the snap-fit ​​33 extends into the slide groove 311 to snap onto the slider of the cleaning ring 2. The portion of the snap-fit ​​33 located in the slide groove 311 is provided with a relief slope 331. When the cleaning ring 2 moves away from the base 1, the cleaning ring 2 can slide against the relief slope 331 to push the snap-fit ​​33, so that the front end of the snap-fit ​​33 exits the slide groove 311, which facilitates operation.

[0054] Preferably, the connecting assembly 3 further includes a spring disposed within the connecting frame 31. The spring is configured to drive the snap-fit ​​member 33 to move so that the front end of the snap-fit ​​member 33 extends into the slide groove 311, thereby ensuring that after the cleaning ring 2 passes over the snap-fit ​​member 33, the snap-fit ​​member 33 can automatically enter the slide groove 311 to snap the cleaning ring 2.

[0055] like Figure 4 As shown, the cleaning ring 2 has a gathering groove 21 on the side facing the base 1. The gathering groove 21 has a second inclined surface 22, which surrounds the permanent magnet rod 100 and is inclined away from the base 1 in a direction away from the permanent magnet rod 100. The second inclined surface 22 can ensure that the contact area between the cleaning ring 2 and the metal particles is small, thereby improving the effect of scraping off the metal particles, and can also make the scraped metal particles move along the second inclined surface 22, thereby moving the scraped metal particles away from the permanent magnet rod 100.

[0056] Preferably, the gathering groove 21 has a third inclined surface 23, which surrounds and connects to the second inclined surface 22. The second inclined surface 22 is inclined towards the base 1 in a direction away from the permanent magnet 100. The third inclined surface 23 and the second inclined surface 22 form a groove, which can gather the metal particles and prevent the scraped metal particles from crossing the edge of the cleaning ring 2 and moving to the side of the cleaning ring 2 away from the base 1, where they will be re-attracted by the permanent magnet 100. This ensures that all the scraped metal particles fall onto the first inclined surface 12 of the base 1 and slide off, thus ensuring the cleaning effect.

[0057] In this embodiment, the outer surface of the cleaning ring 2 has an antimagnetic layer made of a non-magnetic material. A non-magnetic material is one that cannot be magnetized, meaning that scraped-off metal particles will not be attracted to the cleaning ring 2, thus ensuring that all scraped-off metal particles fall off and facilitating the cleaning of the cleaning ring 2.

[0058] Preferably, the antimagnetic layer can be further made of an oleophobic material, such as polytetrafluoroethylene. The use of an oleophobic material in the antimagnetic layer can prevent the surface of the cleaning ring 2 from adsorbing oil, making it easier to clean after use.

[0059] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
