Description

Technical Field

[0001] This utility model belongs to the technical field of battery production equipment, and specifically relates to an iron removal device. Background Technology

[0002] Electrodes are a crucial component in lithium-ion batteries, responsible for electron conduction and ion transport. During lithium-ion battery production, due to raw materials and equipment, electrodes may become contaminated with impurities such as iron filings and iron powder. When iron impurities are introduced into the battery, they can cause short circuits, capacity reduction, and shortened cycle life. To improve battery performance and lifespan, iron filings and iron powder must be removed during electrode production using an iron removal device to ensure the cleanliness of the electrode surface.

[0003] In related technologies, the iron removal device includes a magnetic rod for adsorbing iron impurities. A mounting base is provided on one side of the magnetic rod, and the mounting base is detachably connected to the magnetic rod to support the magnetic rod. When the electrode passes through the magnetic rod, the magnetic rod can remove iron impurities from the surface of the electrode, thereby cleaning the electrode.

[0004] However, the magnetic rods need to be cleaned regularly to remove the impurities they have attracted. When cleaning the magnetic rods, the operator needs to remove the entire magnetic rod from the mounting base. This is especially inconvenient when the magnetic rods are large in size. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides an iron removal device in which a magnetic rod adsorbs impurities through a protective cover. When operators clean the device periodically, they only need to disassemble and clean the protective cover without removing the entire magnetic rod, making the operation convenient.

[0006] The technical effects to be achieved by this utility model are realized through the following technical aspects:

[0007] This utility model provides an iron removal device, including a magnetic rod; a protective cover covering the surface of the magnetic rod, through which the magnetic rod adsorbs iron impurities, and the iron impurities adhere to the outer wall of the protective cover; and a connecting component disposed between the magnetic rod and the protective cover, wherein the magnetic rod and the protective cover are detachably connected via the connecting component.

[0008] In some implementations, the connection component includes a retainer that is fitted over the outside of the magnetic rod and the protective cover.

[0009] In some implementations, the connecting component further includes a magnetic attractant disposed on the protective cover, and the magnetic attractant and the magnetic rod attract each other.

[0010] In some implementations, a rotating assembly for driving the magnetic rod to rotate and adjust is provided on one side of the magnetic rod.

[0011] In some implementations, the rotating assembly includes an adapter plate on which the magnetic rod is disposed; a fixed base on which the adapter plate is rotatably disposed; and a locking member on the adapter plate to lock the adapter plate and restrict its rotation.

[0012] In some implementations, the fixed base has a guide hole, and the adapter plate rotates relative to the fixed base along the guide hole.

[0013] In some implementations, the magnetic rod is movably mounted on the adapter plate, and a horizontal adjustment component is provided between the magnetic rod and the adapter plate, the horizontal adjustment component moving in the horizontal direction to adjust the magnetic rod.

[0014] In some implementations, the horizontal adjustment component includes multiple limiting blocks disposed on the adapter plate, with an adjustment area between the multiple limiting blocks; a mounting base disposed within the adjustment area, the mounting base being movable and adjustable in the horizontal direction within the adjustment area, and a magnetic rod disposed on the mounting base; and an adjustment screw including a connecting end and a pushing end, the connecting end being threadedly connected to the adapter plate, and the pushing end being movably connected to the mounting base and pushing the mounting base to move within the adjustment area.

[0015] In some implementations, the mounting base is provided with an adjusting block, and the adjusting block has a limiting groove; the pushing end is provided with a limiting head, the limiting head is movably disposed in the limiting groove, and the adjusting block restricts the limiting head from moving horizontally and disengaging from the mounting base at the limiting groove.

[0016] In some implementations, the protective cover is adapted to the magnetic rod.

[0017] In summary, this utility model has at least the following advantages:

[0018] The iron removal device provided by this utility model has a protective cover placed on the surface of a magnetic rod, and a connecting assembly connects the magnetic rod and the protective cover. During iron removal from the electrode, the protective cover adsorbs impurities on the surface of the electrode under the magnetic attraction of the magnetic rod, and the iron impurities can adhere to the outer wall of the protective cover. After the iron removal device has been used for a period of time, the operator only needs to disassemble and clean the protective cover to remove the iron impurities adsorbed by the magnetic rod, ensuring the normal operation of the iron removal device. Compared with traditional iron removal devices, the operator does not need to disassemble the entire magnetic rod, making cleaning and operation convenient and saving time for daily maintenance of the iron removal device to a certain extent.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] Example 1:

[0031] Please see the appendix Figure 1 and Figure 2The iron removal device of this utility model includes a magnetic rod 1 and a protective cover 2. A connecting component 3 is provided between the magnetic rod 1 and the protective cover 2. During iron removal, iron impurities are adsorbed onto the protective cover 2. The protective cover 2 protects the magnetic rod 1 and facilitates the cleaning of impurities.

[0032] Please refer to the appendix for details. Figure 1 The protective cover 2 is placed over the surface of the magnetic rod 1. In some specific embodiments, the protective cover 2 is preferably, but not limited to, a plastic cover, especially an acrylic cover, which is easy to replace and has low operating costs. During iron removal, the protective cover 2 covers the side of the magnetic rod 1 closest to the electrode. The electrode passes through the magnetic rod 1 and the protective cover 2. The magnetic rod 1's adsorption force on the iron impurities attracts the iron impurities to the outer wall of the protective cover 2. The protective cover 2 separates the magnetic rod 1 from the iron impurities. The operator can clean the protective cover 2 when cleaning the iron impurities.

[0033] Please see the appendix Figure 2 A connecting component 3 is disposed between the magnetic rod 1 and the protective cover 2, allowing for a detachable connection between the magnetic rod 1 and the protective cover 2. In a preferred embodiment, the connecting component 3 includes a retaining pad 31, which is fitted over the outer sides of the magnetic rod 1 and the protective cover 2. The protective cover 2 is stably positioned over the magnetic rod 1, and the retaining pad 31, the protective cover 2, and the magnetic rod 1 are interlocked. When cleaning the protective cover 2, the retaining pad 31 is simply removed from the protective cover 2 and the magnetic rod 1, resulting in a simple structure and convenient operation. Specifically, the retaining pad 31 is preferably, but not limited to, a soft rubber retaining pad, which effectively reduces the risk of fingers being pinched by the retaining pad 31 during assembly.

[0034] Furthermore, the connecting component 3 also includes a magnetic suction element 32, which is disposed on the protective cover 2. The magnetic suction element 32 and the magnetic rod 1 are attracted to each other, thereby further fixing the magnetic rod 1 and the protective cover 2 during assembly. Specifically, the magnetic suction element 32 can be a magnet. When the retaining pad 31 is pulled out, the protective cover 2 will fall quickly after losing the fixation of the retaining pad 31, which may injure the operator or other equipment. The setting of the magnetic suction element 32 ensures that after the retaining pad 31 is removed, the protective cover 2 and the magnetic rod 1 remain in an attracted state, thereby reducing the probability of safety accidents.

[0035] In some other specific embodiments, the connecting component 3 may include multiple magnetic sheets, which are attached to the inner wall of the protective cover 2. The protective cover 2 is detachably connected only by the magnetic sheets attracting the magnetic rod 1.

[0036] The electrode sheet undergoes surface iron removal via magnetic rod 1 and protective cover 2. After the outer wall of protective cover 2 is magnetically attracted by the magnetic rod 1, a certain amount of iron impurities are adsorbed, requiring cleaning for reuse. Removing the retaining pad 31 separates protective cover 2 from magnetic rod 1. Operators can then clean protective cover 2 independently without disassembling magnetic rod 1, making disassembly and cleaning of protective cover 2 convenient. Simultaneously, protective cover 2 protects magnetic rod 1, reducing the need for frequent cleaning and extending its lifespan.

[0037] In a preferred embodiment, the protective cover 2 is adapted to the magnetic rod 1, which helps to increase the adsorption area of ​​the protective cover 2 for ferrous impurities. Under the magnetic attraction of the magnetic rod 1, the protective cover 2 fully adsorbs the ferrous impurities on the surface of the electrode, while the surface of the magnetic rod 1 is less prone to ferrous impurities adhering to it. In the specific embodiment shown, the magnetic rod 1 is a rectangular rod, and the protective cover 2 is a U-shaped cover. The surface of the magnetic rod 1 is in contact with the inner wall of the protective cover 2. The protective cover 2 can fully cover the surface of the magnetic rod 1 while being easy to disassemble.

[0038] Example 2:

[0039] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the magnetic rod 1 of this utility model. Please refer to [link / reference]. Figure 3 and Figure 4 .

[0040] Please see Figure 3 In this embodiment, a rotating assembly 4 for driving the magnetic rod 1 to rotate is provided on one side. The operator drives the magnetic rod 1 to rotate through the rotating assembly 4. The magnetic rod 1 can be rotated and adjusted according to the direction of the electrode. The protective cover 2 rotates with the magnetic rod 1 to a state that can fully adsorb iron impurities on the surface of the electrode. At the same time, the magnetic rod 1 and the protective cover 2 can rotate. When cleaning the protective cover 2, the operator can rotate the magnetic rod 1 and the protective cover 2 to an angle that is easy to disassemble and clean.

[0041] In a preferred embodiment, the rotating assembly 4 includes an adapter plate 41. Specifically, the adapter plate 41 is located at both ends of the magnetic rod 1 along its length, and the magnetic rod 1 is mounted on the adapter plate 41. A fixing seat 42 is provided on the side of the adapter plate 41 away from the magnetic rod 1. The adapter plate 41 is rotatably mounted on the fixing seat 42. Specifically, a rotating shaft 44 is provided between the fixing seat 42 and the adapter plate 41, and a rotatable connection is achieved through the rotating shaft 44.

[0042] Please see Figure 4 In some specific embodiments, the fixed base 42 is provided with a guide hole 421, which is specifically an arc-shaped hole. The adapter plate 41 rotates relative to the fixed base 42 along the guide hole 421. The adapter plate 41 may be provided with a guide post or screw, which passes through the guide hole 421 and moves within the guide hole 421 as the adapter plate 41 rotates. The opening of the guide hole 421 can guide the rotation of the adapter plate 41, ensure the stability of the rotation of the adapter plate 41, and limit the rotation angle of the adapter plate 41 for easy adjustment.

[0043] Please see Figure 3A locking element 43 is provided between the adapter plate 41 and the fixing base 42 to lock the adapter plate 41, restricting the rotation of the adapter plate 41. Specifically, the locking element 43 is preferably, but not limited to, a push-button locking pin. The locking element 43 locks the adapter plate 41 and the magnetic rod 1, preventing misalignment between the protective cover 2 and the electrode plate due to automatic rotation of the adapter plate 41 and the magnetic rod 1. It is understood that the locking method of the push-button locking pin is known to those skilled in the art and is achievable, and will not be described in detail in this embodiment.

[0044] In some other specific embodiments, the locking member 43 may be a connecting sleeve, which is disposed on the adapter plate 41 and sleeved on the rotating shaft 44. A bolt is passed through the connecting sleeve, and the bolt is threaded with a nut and cooperates with the nut to make the connecting sleeve tighten or loosen the rotating shaft 44. The adapter plate 41 achieves locking after rotation through the connecting sleeve, bolt and nut.

[0045] The rotating component 4 has a simple structure and flexible operation, which helps to further improve the ease of cleaning the protective cover 2.

[0046] Example 3:

[0047] The difference between this embodiment and the above embodiments is that, please refer to [link / reference needed]. Figures 5-7 In this embodiment, the magnetic rod 1 is movably mounted on the adapter plate 41. A horizontal adjustment component 5 is provided between the magnetic rod 1 and the adapter plate 41. The horizontal adjustment component 5 moves in the horizontal direction to adjust the magnetic rod 1. For details, please refer to [link to relevant documentation]. Figure 5 and Figure 7 In this embodiment, the horizontal adjustment component 5 can adjust the position of the magnetic rod 1 along the X-axis.

[0048] In a preferred embodiment, the horizontal adjustment component 5 includes a plurality of limiting blocks 51, which are disposed on the adapter plate 41, and an adjustment area 52 is provided between the plurality of limiting blocks 51. Specifically, the limiting blocks 51 are provided with scales, and the horizontal adjustment component 5 can adjust the moving distance of the magnetic rod 1 according to the scales.

[0049] The adapter plate 41 has a mounting base 53 within the adjustment area 52. Multiple limiting blocks 51 are respectively located at both ends of the mounting base 53 moving along the Z-axis to restrict its movement. A magnetic rod 1 is mounted on the mounting base 53. Specifically, the magnetic rod 1 is detachably connected to the mounting base 53. A connecting piece is provided on the magnetic rod 1, and the connecting piece and the mounting base 53 can be assembled using bolts. The operator adjusts the mounting base 53 to adjust the position of the magnetic rod 1 horizontally. Specifically, when the retaining pad 31 is fitted over the magnetic rod 1 and the protective cover 2, a certain space is maintained between the retaining pad 31 and the mounting base 53, allowing the retaining pad 31 to be easily removed from the protective cover 2 and the magnetic rod 1.

[0050] Furthermore, the mounting base 53 is provided with an adjustment block 55. Specifically, there are two adjustment blocks 55, which are distributed along the Z-axis direction, and adjustment grooves are provided on the adjustment blocks 55.

[0051] The adapter plate 41 is provided with a connecting block, and an adjusting screw 54 is passed through the connecting block. The adjusting screw 54 includes a connecting end 541 and a pushing end 542. The connecting end 541 is threadedly connected to the connecting block, and the pushing end 542 is passed between two adjusting blocks 55. When the adjusting screw 54 rotates, the pushing end 542 can push the mounting base 53 to move horizontally in the adjustment area 52 to achieve adjustment.

[0052] Please see Figure 6 A limiting head 543 is provided on the pushing end 542. The limiting head 543 is movably disposed within the limiting groove 551. The adjusting block 55 restricts the limiting head 543 from moving horizontally and disengaging it from the mounting base 53 at the limiting groove 551. When the magnetic rod 1 is adjusted horizontally, rotating the adjusting screw 54 causes the limiting head 543 to push the mounting base 53 to move. Rotating the adjusting screw 54 in the opposite direction allows the mounting base 53 to move in the opposite direction to return to its initial position. The magnetic rod 1 drives the mounting base 53 to move horizontally through the adjusting screw 54 to adapt to the belt travel direction of the electrode sheet in the actual production process, improving the flexibility of use.
