[0020] In this application, the direction parallel to the electrode is the first direction, and the direction perpendicular to the electrode is the second direction.

[0021] Please see Figure 1 and Figure 2 The guide rod 1 is arranged along the first direction and is slidably connected to the linear bearing 2, meaning the linear bearing 2 also slides along the first direction on the guide rod 1. The device moving plate 3 is fixedly connected to the linear bearing 2. In this embodiment, the device moving plate 3 and the linear bearing 2 are fixedly connected by bolts. The magnetic suction assembly 4 is fixed to the side of the device moving plate 3 near the electrode. Please refer to [link to relevant documentation]. Figure 1 and Figure 3Specifically, the magnetic component 4 includes a base 4a, a magnetic unit 4b, and a guide sheet metal 4c. The base 4a and the guide sheet metal 4c are arranged along a first direction. One side of the base 4a is fixedly connected to the device moving plate 3, and the other side is fixedly connected to the guide sheet metal 4c. The magnetic unit 4b is arranged between the guide sheet metal 4c and the base 4a and abuts against the guide sheet metal 4c to provide magnetism to the guide sheet metal 4c. The contact surface between the guide sheet metal 4c and the pole piece is coated with Teflon. The two sides of the base are rounded to prevent scratching the pole piece. The magnetic unit 4b can be made of a material with strong magnetism, such as a neodymium iron boron magnet with a magnetic field strength of 12,000 gauss. Preferably, the electrode iron removal device further includes a front end fixing plate 5, which is fixedly connected to one side of the guide rod 1. In this embodiment, the front end fixing plate 5 and the guide rod 1 are fixedly connected by bolts. The lower side of the base 4a abuts against the upper end of the front end fixing plate 5.

In this embodiment, the guide rod 1 and the adjusting plate 8b are fixedly connected by bolts. The adjusting bolt 8c is arranged along the second direction, with one end abutting against the fixed plate 8a and the other end threadedly connected to the adjusting plate 8b. More preferably, the adjusting plate 8b has an oblong hole along the second direction for bolting the adjusting plate 8b and the fixed plate 8a. The adjusting bolt 8c is used to move the position of the adjusting plate 8b within a range of 0-20mm. Its function is to facilitate the adjustment of the distance from the magnetic unit 4b to the electrode to achieve the optimal iron removal effect. After adjustment, the bolt is locked in the oblong hole to fix the fixed plate 8a and the adjusting plate 8b.

[0024] In summary, the electrode iron removal device provided in this application allows for the strong magnetic attraction of metallic impurities on the electrode surface to the magnetic component 4 when the electrode passes through it.
