Abstract
Description
Technical Field
[0001] This utility model relates to the field of iron removal technology for lithium battery electrode sheets, and specifically to a pull-out iron removal device. Background Technology
[0002] With technological advancements and increased environmental awareness, electric vehicles are becoming increasingly popular. Safety is a top priority for consumers, and lithium batteries, as the power source for new energy vehicles, are a key consideration in their safety.
[0003] The production process of lithium battery electrode sheets generally includes processes such as slurry preparation, coating, rolling, slitting, and sheet making. Since the production workshop is not enclosed, the electrode sheets will inevitably be contaminated with iron filings during production. Iron filings are sharp metal conductors that can easily scratch or puncture the electrode sheets, causing battery self-discharge, capacity loss or bulging, and in severe cases, battery fire or explosion.
[0004] Currently, existing iron removal devices are generally fixedly connected to equipment. Although they can remove iron, the iron removal efficiency is not high because the equipment space is small, the position is limited, and the iron filings on the magnetic rod or magnet are difficult to clean and maintain.

The magnet assembly is installed on the frame body and located below the pole piece. A dovetail groove plate is installed on the frame body, and the surface of the dovetail groove plate is provided with a groove. A dovetail block matching the groove is installed at the bottom of the magnet assembly. The dovetail block is slidably installed in the groove. The magnet assembly is detachably connected to the frame body.
[0006] Furthermore, the magnet assembly includes a magnet, the top of which is a working surface, which is arranged parallel to the pole piece, and a dovetail block is installed at the bottom of the magnet.

The iron filings removal seat has a connecting hole in the middle for the magnet assembly to pass through. The iron filings removal block is installed in the connecting hole and abuts against the working surface of the magnet.
[0010] Furthermore, the metal shavings assembly also includes an elastic mechanism, through which the metal shavings block is connected to the metal shavings seat, and the metal shavings block moves closer to or further away from the working surface of the magnet under the action of the elastic mechanism.
[0011] Furthermore, the groove is provided with a mounting hole, and a positioning bead is installed in the mounting hole by a compression spring. The dovetail block has a recess. When the positioning bead protrudes from the surface of the groove and mates with the recess under the elastic force of the compression spring, the magnet assembly is installed in place.
[0012] Furthermore, the frame body includes a cylinder and a fixed base. The cylinder is fixedly installed on the fixed base, and the dovetail groove plate is fixedly installed on the telescopic rod of the cylinder. The dovetail groove plate moves closer to or further away from the electrode under the action of the cylinder.
[0013] Furthermore, the cross-sectional shape of the groove is polygonal or irregular.
[0014] Beneficial effects:
[0015] 1. In this utility model, the dovetail groove plate, groove and dovetail block can be set to allow the magnet assembly and the frame body to be freely combined or separated, thereby facilitating the cleaning of iron filings adsorbed on the magnet assembly and improving the iron removal efficiency.

[0016] 2. In this utility model, the magnet and the arrangement of the working surface of the magnet parallel to the pole piece can facilitate the adsorption of iron filings; the handle can be used to control the sliding of the magnet relative to the main frame; and the adapter can be used to adjust the position of the handle relative to the end face of the magnet, making it easy to hold and also facilitating the installation and fixing of the handle and the magnet.
[0017] 3. In this utility model, by setting up an iron filings cleaning assembly including an iron filings cleaning block, an iron filings cleaning seat, and two upright plates, the iron filings on the surface of the magnet can be cleaned while the magnet is being pulled and slid, thereby greatly improving the efficiency of cleaning iron filings on the magnet; combined with the setting of the elastic mechanism, it can ensure that the iron filings cleaning block is always in close contact with the working surface of the magnet, improving the cleaning effect, and at the same time, it can buffer the iron filings cleaning block to prevent the iron filings cleaning block from getting stuck with the magnet.
[0018] 4. In this utility model, the installation holes, compression springs, positioning beads and recesses make it easy to position the magnet assembly, improving installation efficiency.

[0034] This utility model provides a pull-out type iron removal device, such as Figure 1 , Figure 3 and Figure 5 As shown, the device includes a frame body 1 and a magnet assembly 2. The magnet assembly 2 is mounted on the frame body 1 and located below the pole piece 4. A dovetail groove plate 10 is mounted on the frame body 1. The surface of the dovetail groove plate 10 is provided with a groove 101. A dovetail block 23 matching the groove 101 is mounted at the bottom of the magnet assembly 2. The dovetail block 23 is slidably mounted in the groove 101. The cross-sectional shape of the groove 101 is polygonal or irregular to prevent the dovetail block 23 from detaching from the groove 101. The magnet assembly 2 is detachably connected to the frame body 1. Specifically, the dovetail block 23 can slide out from both ends of the groove 101.
[0035] In this embodiment, the dovetail plate 10, groove 101, and dovetail block 23 allow the magnet assembly 2 and the frame body 1 to be freely combined or separated, thus facilitating the cleaning of iron filings adsorbed on the magnet assembly 2 and improving the iron removal efficiency. Combined with the dovetail block 23 being slidably installed in the groove 101, the relative position of the magnet assembly 2 and the pole piece 4 can be freely adjusted to ensure that the adsorption capacity of the magnet assembly 2 can be fully utilized. Specifically, when the iron filings adsorbed on a certain section of the magnet assembly 2 reach saturation, and there are still iron filings to be adsorbed on the corresponding pole piece 4, the relative position of the magnet assembly 2 and the pole piece 4 can be changed by sliding the magnet assembly 2 until all positions on the magnet assembly 2 reach saturation.
[0036] In this utility model, preferably, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the magnet assembly 2 includes a magnet 20, the top of which is a magnet working surface 201, which is arranged parallel to the pole piece 4, and a dovetail block 23 is installed at the bottom of the magnet 20; the magnet assembly 2 also includes a handle 22, which is fixedly installed at one end of the magnet 20; the magnet assembly 2 also includes an adapter 21, through which the handle 22 is fixedly connected to the magnet 20.
[0037] In this embodiment, the magnet 20 and the working surface 201 of the magnet are arranged parallel to the pole piece 4, which facilitates the adsorption of iron filings; the handle 22 facilitates the sliding of the magnet 20 relative to the frame body 1; and the adapter 21 facilitates the adjustment of the position of the handle 22 relative to the end face of the magnet 20, making it easy to hold and also facilitates the installation and fixation of the handle 22 and the magnet 20.
[0038] In this utility model, preferably, such as Figures 1 to 5 As shown, a pull-out iron removal device also includes an iron filings cleaning assembly 3. The iron filings cleaning assembly 3 includes an iron filings cleaning block 30, an iron filings cleaning seat 31, and two upright plates 32. The iron filings cleaning block 30 is fixedly installed at one end of the dovetail groove plate 10 through the two upright plates 32. The iron filings cleaning seat 31 has a connecting hole in the middle for the magnet assembly 2 to pass through. The iron filings cleaning block 30 is installed in the connecting hole and abuts against the working surface 201 of the magnet. The iron filings cleaning block 30 is a flexible brush, a rubber block, or other similar material, which can clean the iron filings adsorbed on the magnet 20 without scratching the magnet 20. The iron filings cleaning assembly 3 also includes an elastic mechanism 33. The iron filings cleaning block 30 is connected to the iron filings cleaning seat 31 through the elastic mechanism 33. The iron filings cleaning block 30 moves closer to or away from the working surface 201 of the magnet under the action of the elastic mechanism 33.
[0039] In this embodiment, by setting up the iron filings cleaning assembly 3, which includes an iron filings cleaning block 30, an iron filings cleaning seat 31, and two upright plates 32, the iron filings on the surface of the magnet 20 can be cleaned while the magnet 20 is being pulled and slid, thereby greatly improving the iron filings cleaning efficiency on the magnet 20. At the same time, it can prevent the magnet assembly 2 from completely disengaging from the groove 101, reducing the time for the magnet assembly 2 to engage with the groove 101, and thus improving the installation efficiency of the magnet assembly 2. Combined with the setting of the elastic mechanism 33, it can ensure that the iron filings cleaning block 30 is always in close contact with the working surface 201 of the magnet, improving the cleaning effect. At the same time, it can buffer the iron filings cleaning block 30 and prevent the iron filings cleaning block 30 from getting stuck with the magnet 20.
[0040] In this utility model, preferably, such as Figure 3 , Figure 4 and Figure 5As shown, the groove 101 is provided with a mounting hole, which can be located near the handle 22 for easy position determination. A positioning bead 13 is installed in the mounting hole by a compression spring. The dovetail block 23 has a recess 231. When the positioning bead 13 protrudes from the surface of the groove 101 and mates with the recess 231 under the elastic force of the compression spring, the magnet assembly 2 is installed in place. During installation, the positioning bead 13 is compressed into the mounting hole by the compression of the magnet assembly 2 and the dovetail block 23. At this time, the compression spring is further compressed. When the magnet assembly 2 is installed in place, the recess 231 on the dovetail block 23 is exactly above the positioning bead 13. At this time, the positioning bead 13 enters the recess 231 under the elastic force of the compression spring. Due to the obstruction of the positioning bead 13, the sliding resistance of the magnet assembly 2 will increase. At the same time, the compression spring will pop out with a clear sound, so the operator can confirm that the two are installed in place. When disassembly is required, first pull the magnet assembly 2 with great force to make the positioning bead 13 disengage from the recess 231, and then reduce the force and continue to pull the magnet assembly 2 until the dovetail block 23 disengages from the groove 101.
[0041] In this embodiment, the installation position of the magnet assembly 2 can be conveniently positioned by the installation hole, compression spring, positioning bead 13 and recess 231, which improves the installation efficiency. At the same time, there is no need for manual confirmation of whether the magnet assembly 2 has been placed in place, saving labor costs.
[0042] In this utility model, preferably, such as Figure 3 As shown, the frame body 1 includes a cylinder 11 and a fixed base 12. The cylinder 11 is fixedly installed on the fixed base 12, and the dovetail groove plate 10 is fixedly installed on the telescopic rod of the cylinder 11. The dovetail groove plate 10 moves closer to or further away from the electrode 4 under the action of the cylinder 11.
[0043] In this embodiment, the distance between the magnet 20 and the pole piece 4 can be easily adjusted by the setting of the cylinder 11 and the fixed base 12, which facilitates the adjustment of the magnetic force of the magnet 20.
[0044] 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.
[0045] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
