Description

Technical Field

[0001] The utility model relates to the technical field of new energy battery production, and more specifically, to a magnetic suction device for cleaning metal foreign matter on battery pole pieces when processing battery pole pieces. Background Art

[0002] During battery manufacturing, the control of metallic foreign matter is crucial and must be implemented throughout every step of the production process. This is because if metallic impurities are present in the electrode material, they can penetrate the separator inside the battery, causing a short circuit, which in turn can lead to safety hazards such as battery overheating or even fire. Furthermore, the presence of metallic foreign matter can cause self-discharge in the battery, affecting the consistency of the battery cells. Therefore, the removal of metallic foreign matter from the electrode material is essential throughout the production process, including raw material extraction, slurry preparation, coating, pressing, and battery core winding.

[0003] A Chinese invention patent application, publication number CN116351558A, discloses a device for cleaning metal foreign matter from electrode pole pieces. The device employs a magnetic rod to adsorb magnetic metal impurities. The rod is also rotatable to adjust the distance between the rod and the pole piece, optimizing the adsorption of magnetic metal impurities. The angle of the magnetic rod is adjusted based on actual needs. However, the device does not describe in detail how to precisely control the angle of the magnetic rod, and its accompanying drawings do not provide detailed information. Therefore, it is necessary to provide improvements to this method. Utility Model Content

[0041] In the production of new energy batteries, magnets with magnetic field strengths between 8,000 and 12,000 gauss are commonly used to effectively remove metal dust generated during pole piece processing. However, the relative angle between the magnetic bar and the pole piece significantly affects the efficiency of metal dust absorption. To address this issue, the present application provides a magnetic attraction device with an adjustable and precisely controlled magnetic bar angle.

[0042] The following embodiments are used to describe in detail an angle-adjustable magnetic device of the present application.

[0043] Example 1:

[0044] like Figure 1-Figure 5 As shown, in this embodiment, an angle-adjustable magnetic device includes: a mounting base 100; a rotating base 200 rotatably disposed on the mounting base 100; and a magnetic rod assembly 300 disposed on the rotating base 200;

[0045] Among them, there are several indexing holes 110 opened on the mounting base 100 along the circumferential direction of the rotating base 200; a first locking member 210 is provided on the rotating base 200, which is used to cooperate with the corresponding indexing hole 110 after adjusting the angle of the rotating base 200 to limit the free rotation of the rotating base 200.

[0046] The mounting base 100 is installed on the pole piece production line, and the magnetic bar assembly 300 is then mounted on the mounting base 100. The magnetic bar assembly 300 is used to clean metal dust from the pole piece surface. To improve the adsorption effect of the magnetic bar assembly 300, a rotating base 200 is added between the mounting base 100 and the magnetic bar assembly 300. By rotating the rotating base 200, the angle between the magnetic bar assembly 300 and the pole piece can be adjusted. Furthermore, the indexing hole 110 and the first locking member 210 are provided to precisely adjust the angle of the magnetic bar assembly 300.

[0047] Specifically, the mounting seat 100 has a through hole in the middle, and a bearing 101 is installed at one end of the through hole. The rotating base 200 has a rotating shaft 201. After the rotating shaft 201 passes through the through hole, it is interference fit with the bearing 101. To prevent the rotating shaft 201 from loosening, a locking nut is threadedly connected to the end of the rotating shaft 201 extending out of the bearing 101, and the locking nut is against the mounting seat 100.

[0048] It should be noted that the rotating base 200 can be rotated on the mounting base 100 by disengaging the first locking member 210 from the indexing hole 110. To facilitate operation, an indexing pin is used as the first locking member 210. The indexing pin is installed on the rotating base 200 and then pulled outward to move it outward, disengaging it from the indexing hole 110. The indexing pin is then pressed to engage it in the indexing hole 110, thereby locking and unlocking the rotating base 200.

[0049] Example 2:

[0050] This embodiment is a further improvement based on the first embodiment.

[0051] like Figure 1-Figure 5As shown, in this embodiment, the magnetic bar assembly 300 is detachably disposed on the rotating base 200 .

[0052] After the magnetic bar assembly 300 absorbs a certain amount of metal impurities, it needs to be cleaned. If the staff manually cleans the magnetic bar assembly 300 on the production line, it will not only affect production but also be difficult to clean completely. Therefore, the magnetic bar assembly 300 is installed on the rotating base 200 via a quick release method. When cleaning, the magnetic bar assembly 300 can be removed for cleaning and then reinstalled after cleaning is completed, which is very convenient.

[0053] Specifically, one end of the magnetic bar assembly 300 is plugged into the rotating base 200;

[0054] The rotating base 200 is provided with a mounting back plate 220 , and the mounting back plate 220 is provided with a second locking member 230 for limiting the magnetic bar assembly 300 from being separated from the rotating base 200 or from being restricted along its plugging direction.

[0055] The magnetic bar assembly 300 includes: a fixing base 310; and a magnetic bar 320, which is disposed on the fixing base 310;

[0056] The magnetic bar assembly 300 is connected to the rotating base 200 and the second locking member 230 via the fixing base 310 .

[0057] First, the magnetic bar 320 is installed on the fixing base 310, and then the upper end of the fixing base 310 is plugged into the rotating base 200. Then, the lower end of the fixing base 310 is restricted by the second locking member 230 so that the fixing base 310 cannot be separated from the mounting back plate 220 and the rotating base 200, thereby completing the installation of the magnetic bar 320 assembly 300.

[0058] On the contrary, when disassembly is required, the second locking member 230 is separated from the fixing base 310 , and then the fixing base 310 is pulled away from its plugging direction to remove the fixing base 310 .

[0059] In this embodiment, it should be noted that both ends of the fixing base 310 have mounting bosses 311 , and both ends of the magnetic bar 320 are connected to the two mounting bosses 311 via bolts.

[0060] In this embodiment, it should be noted that a socket is provided on the rotating base 200 and a plug that matches the socket is provided on the fixing base 310;

[0061] Alternatively, the rotating base 200 is provided with a plug post 240 , and the fixing base 310 is provided with a socket 312 that matches the plug post 240 .

[0062] Example 3:

[0063] This embodiment is a further improvement made on the basis of the second embodiment.

[0064] like Figure 1 、 Figure 2 and Figure 5 As shown, in this embodiment, a notch groove 221 is formed on the end of the mounting back plate 220 away from the rotating base 200, and a limiting rod 313 is provided on the fixing base 310. One end of the limiting rod 313 passes through the notch groove 221 and abuts against the mounting back plate 220.

[0065] The second locking member 230 is used to prevent the limiting rod 313 from being separated from the opening direction of the notch groove 221 .

[0066] After the upper end of the fixing seat 310 is inserted into the rotating base 200, the limiting rod 313 on the lower side of the fixing seat 310 enters the notch groove 221 along the opening direction of the notch groove 221, and then the opening on the notch groove 221 is blocked by the second locking member 230, thereby realizing the installation of the fixing seat 310.

[0067] In this embodiment, it should be noted that the end of the limiting rod 313 has a limiting head, which abuts against the mounting back plate 220. This arrangement can prevent the fixing seat 310 from loosening.

[0068] In this embodiment, it should be noted that the second locking member is an indexing pin that passes through the mounting back plate 220 and can be inserted into the notch groove 221. The indexing pin is used to limit the position of the limiting rod 313 on the fixing seat 310.

[0069] Specifically, when the second locking piece is embedded in the notch groove 221, the opening of the notch groove 221 is blocked. At this time, the limit rod 313 is located above the second locking piece and is in a cross-cross state with the second locking piece, so that the second locking piece limits the movement of the limit rod 313; when disassembly is required, the second locking piece is pulled out from the notch groove 221, so that the limit rod 313 can be separated from the notch groove 221, which is very convenient and practical, and achieves the purpose of quick disassembly and quick assembly.

[0070] Example 4:

[0071] This embodiment is a further improvement made on the basis of the second and third embodiments.

[0072] like Figure 1 and Figure 2 As shown, in this embodiment, baffles 250 located on both sides of the mounting back plate 220 are further provided on the rotating base 200 , and the magnetic bar assembly 300 is located in a chamber enclosed by the two baffles 250 and the mounting back plate 220 .

[0073] The baffle 250 can protect the magnetic bar assembly 300 on the one hand, and can reduce the entry of dust into the magnetic bar assembly 300 on the other hand.

[0074] While various embodiments of the present disclosure have been described above, the above descriptions are intended to be illustrative, non-exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or improvements to existing technologies, or to enable others skilled in the art to understand the embodiments disclosed herein.
