[0002] Battery electrodes are an important component of lithium batteries. The production process of battery electrodes includes processes such as mixing, coating, rolling, slitting, and electrode tab welding. During the process, iron filings will adhere to their surface. Battery electrodes with iron filings will cause battery self-discharge and capacity loss. When the metal filings accumulate to a certain extent, they will puncture the battery separator and electrodes, causing battery self-discharge and short circuit problems.

[0003] In related technologies, the iron removal mechanism includes two parallel magnetic rods, with an electrode passing through the middle of the two magnetic rods. Although this method effectively removes iron from the electrode, the iron filings attracted to the magnetic rods need to be cleaned periodically; otherwise, the magnetic attraction of the rods will be affected. Currently, manual cleaning of the magnetic rods is often performed periodically, but the magnetic attraction of the rods makes it difficult to remove the iron filings, resulting in a time-consuming and labor-intensive process.

[0040] like Figure 1 and Figure 2As shown, an embodiment of this application provides an electrode iron removal device 100, which is mainly used in battery production equipment. The electrode iron removal device 100 includes a mounting component 110, a magnetic component 120, a separator 130, and a first fastener.

[0041] The mounting component 110 has a mounting groove 111, the magnetic suction component 120 is disposed in the mounting groove 111, and the isolation component 130 covers the opening of the mounting groove 111. The mounting component 110 has a first fastening hole 112, and the isolation component 130 has a second fastening hole 1321. The first fastener passes through the second fastening hole 1321 and the first fastening hole 112 in sequence, so that the isolation component 130 is detachably connected to the mounting component 110.

[0042] The electrode iron removal device 100 provided in the embodiments of this application, by opening a first fastening hole 112 and a second fastening hole 1321 on the mounting member 110 and the isolation member 130 respectively, and sequentially passing a first fastener through the second fastening hole 1321 and the first fastening hole 112, makes the isolation member 130 detachably connected to the mounting member 110. Thus, when it is necessary to clean the metal filings on the isolation member 130, it is only necessary to remove the isolation member 130 from the mounting member 110 and move it away from the magnetic suction member 120, so that the metal filings can automatically detach from the isolation member 130, effectively improving the cleaning efficiency.

[0043] For example, the magnetic attractor 120 can be a permanent magnet, the first fastener can be a fastening screw, the first fastening hole 112 can be a fastening screw hole, and the second fastening hole 1321 can be a through hole.

[0044] like Figure 1 and Figure 2 As shown, in one embodiment of this application, the isolation member 130 includes an isolation part 131 and a connecting part 132. The connecting part 132 is perpendicularly connected to the isolation part 131. The isolation part 131 covers the opening of the mounting groove 111. The connecting part 132 has a second fastening hole 1321.

[0045] In this embodiment, the isolation member 130 includes a vertically connected isolation part 131 and a connecting part 132. The isolation part 131 covers the opening of the mounting groove 111 to isolate the magnetic suction member 120 and metal filings. The connecting part 132 has a second fastening hole 1321 so that the isolation part 131 can be detachably connected to the mounting member 110 through the connecting part 132.

[0046] like Figure 1 and Figure 2 As shown, in one embodiment of this application, the edge of the connecting portion 132 is provided with a notch 1322, and the notch 1322 communicates with the second fastening hole 1321.

[0047] In this embodiment, by opening a notch 1322 at the edge of the connecting part 132 that communicates with the second fastening hole 1321, when it is necessary to clean the metal shavings on the isolation member 130, the isolation member 130 can be separated from the mounting member 110 simply by loosening the first fastener, without having to completely unscrew the first fastener, which effectively improves the disassembly efficiency and further improves the cleaning efficiency.

[0048] like Figure 1 and Figure 2 As shown, in one embodiment of this application, the electrode iron removal device 100 further includes a second fastener 140, the mounting groove 111 has a first sidewall 1111, the first sidewall 1111 has a third fastening hole 1112, the second fastener 140 passes through the third fastening hole 1112 and abuts against the magnetic attractor 120.

[0049] In this embodiment, the mounting groove 111 has a first sidewall 1111 and a third fastening hole 1112. By inserting the second fastener 140 through the third fastening hole 1112 and abutting against the magnetic member 120, the magnetic member 120 is detachably installed in the mounting groove 111. When the second fastener 140 is tightened, the magnetic member 120 can be stably installed in the mounting groove 111 under the pressure of the second fastener 140. When the second fastener 140 is loosened, the second fastener 140 is separated from the magnetic member 120, thereby allowing the magnetic member 120 to be disassembled.

[0050] For example, the second fastener 140 can be a fastening screw, and the third fastening hole 1112 can be a fastening screw hole.

[0051] like Figure 1 and Figure 2 As shown, in one embodiment of this application, the second fastener 140 has a first hand-tightening part 141 at the end away from the magnetic member 120.

[0052] In this embodiment, by providing a first hand-tightening part 141 at the end of the second fastener 140 away from the magnetic component 120, the operator can directly tighten or loosen the second fastener 140 by rotating the first hand-tightening part 141 without the need for fastening tools, which effectively improves the installation and disassembly efficiency of the magnetic component 120.

[0053] like Figure 1 and Figure 2As shown, in one embodiment of this application, the electrode iron removal device 100 further includes a first connector 150, the mounting groove 111 has a second sidewall 1113, the second sidewall 1113 and the first sidewall 1111 are respectively located on two opposite sides of the mounting groove 111, the second sidewall 1113 is provided with a first mounting hole 1114 that is adapted to the shape of the first connector 150, and one end of the first connector 150 is disposed in the first mounting hole 1114.

[0054] In this embodiment, the mounting groove 111 has second sidewalls 1113 located on two opposite sides of the mounting groove 111, which are respectively located on the first sidewall 1111. The second sidewall 1113 has a first mounting hole 1114 that is adapted to the shape of the first connector 150. One end of the first connector 150 is disposed in the first mounting hole 1114 to achieve a stable connection between the first connector 150 and the mounting member 110, so that the mounting member 110 can be installed on other components through the first connector 150.

[0055] like Figure 1 and Figure 2 As shown, in one embodiment of this application, the electrode iron removal device 100 further includes a third fastener, and the mounting member 110 has a fourth fastening hole 113 that is perpendicularly connected to the first mounting hole 1114. The third fastener passes through the fourth fastening hole 113 and abuts against the first connecting member 150.

[0056] In this embodiment, by opening a fourth fastening hole 113 on the mounting member 110 that is perpendicularly connected to the first mounting hole 1114, and inserting a third fastener through the fourth fastening hole 113 and abutting against the first connector 150, one end of the first connector 150 is detachably installed in the first mounting hole 1114. When the third fastener is tightened, one end of the first connector 150 can be stably installed in the first mounting hole 1114 under the pressure of the third fastener. When the third fastener is loosened, the third fastener is separated from the first connector 150, thereby allowing the first connector 150 to be disassembled.

[0057] For example, the third fastener can be a fastening screw, and the fourth fastening hole 113 can be a fastening screw hole.

[0058] like Figure 1 and Figure 2 As shown, in one embodiment of this application, the electrode iron removal device 100 further includes a second connector 160, which is used to connect to battery production equipment. The second connector 160 has a second mounting hole 161 that is adapted to the shape of the first connector 150, and one end of the first connector 150 away from the mounting member 110 is disposed in the second mounting hole 161.

[0059] In this embodiment, by opening a second mounting hole 161 on the second connector 160 that matches the shape of the first connector 150, and placing the end of the first connector 150 away from the mounting member 110 in the second mounting hole 161, a stable connection between the first connector 150 and the second connector 160 is achieved, thereby enabling the mounting member 110 to be stably installed on the battery production equipment through the first connector 150 and the second connector 160.

[0060] like Figure 1 and Figure 2 As shown, in one embodiment of this application, the electrode iron removal device 100 further includes a fourth fastener 170, and the second connector 160 has a fifth fastening hole 162 that is perpendicularly connected to the second mounting hole 161. The fourth fastener 170 passes through the fifth fastening hole 162 and abuts against the first connector 150.

[0061] In this embodiment, a fifth fastening hole 162 is opened on the second connector 160, which is perpendicularly connected to the second mounting hole 161. The fourth fastener 170 is inserted through the fifth fastening hole 162 and abuts against the first connector 150. This allows the end of the first connector 150 away from the mounting member 110 to be detachably installed in the second mounting hole 161. When the fourth fastener 170 is tightened, the end of the first connector 150 away from the mounting member 110 can be stably installed in the second mounting hole 161 under the pressure of the fourth fastener 170. When the fourth fastener 170 is loosened, the fourth fastener 170 is separated from the first connector 150, thereby allowing the first connector 150 to be disassembled.

[0062] For example, the fourth fastener 170 can be a fastening screw, and the fifth fastening hole 162 can be a fastening screw hole.
