Claims

1. An automatic cleaning lithium battery pole piece iron removal device, characterized in that, The system includes a magnetic rod, a cleaning chamber, a cleanroom hood, a propulsion and steering module, and a lifting assembly. The magnetic rod is movably positioned between the iron removal station and the cleaning station via the propulsion and steering module. The cleaning chamber is positioned at the cleaning station via the lifting assembly in a swinging manner, and a magnet is installed inside the cleaning chamber. The cleanroom hood is detachably connected to the magnetic rod and the cleaning chamber. At the iron removal station, the cleanroom hood is fitted over the outside of the magnetic rod, and iron filings on the electrodes are attracted and retained on the surface of the cleanroom hood under the magnetic force of the magnetic rod. During the cleaning operation, the propulsion and steering module drives the magnetic rod and the cleanroom hood to move to the cleaning station, where the cleanroom hood docks with the cleaning chamber and separates from the magnetic rod. The lifting assembly causes the cleaning chamber and the cleanroom hood to swing up and down, and the magnet rolls along the cleaning chamber under gravity, attracting the iron filings retained on the surface of the cleanroom hood through magnetic force.

2. The self-cleaning lithium battery pole piece iron removal device of claim 1, wherein, The propulsion and steering module includes a first propulsion component, a second propulsion component, and a steering component. The first and second propulsion components are symmetrically arranged at both ends of the magnetic rod to synchronously drive the magnetic rod to reciprocate between the iron removal station and the cleaning station. The steering component is located outside the first propulsion component and includes a mounting shaft, a follower swing arm, and a guide plate connected in sequence. The mounting shaft is fixed to one end of the magnetic rod and connected to the slider of the first propulsion component. The follower swing arm is movably arranged in the track groove of the guide plate. When the slider drives the mounting shaft and the follower swing arm to reciprocate between the iron removal station and the cleaning station, the follower swing arm moving along the track groove drives the mounting shaft and the magnetic rod to rotate by a certain angle.

3. The self-cleaning lithium battery pole piece iron removal device of claim 2, wherein, At the iron removal station, the magnetic surface of the magnetic rod is positioned facing the pole piece. During the cleaning operation, the steering component drives the magnetic surface of the magnetic rod to rotate toward the cleaning chamber.

4. The self-cleaning lithium battery pole piece iron removal device of claim 2, wherein, Both the first and second propulsion components include a mounting frame, a drive cylinder, a guide rail, and a slider. The drive cylinder and the guide rail are fixed on the mounting frame, and the slider is movably mounted on the guide rail. The drive end of the drive cylinder is connected to the slider, and the slider is provided with a bearing seat that is movably connected to the mounting shaft.

5. The self-cleaning lithium battery pole piece iron removal device of claim 1, wherein, The cleaning chamber includes a chamber body and a pallet. One end of the chamber body is connected to a lifting assembly. The pallet is parallel to the side of the chamber body near the iron removal station. The magnet is movably disposed inside the chamber body. The chamber body has a feed inlet on one side of the pallet for iron filings to enter. During cleaning operations, the cleaning hood is placed on the pallet and separated from the magnetic rod by the propulsion and steering assembly. The iron filings retained on the cleaning hood approach the feed inlet facing the chamber body. The lifting assembly causes a change in the height of one end of the chamber body. The magnet rolls along the chamber body under gravity and attracts the iron filings at the cleaning hood through magnetic force.

6. The self-cleaning lithium battery pole piece iron removal device of claim 5, wherein, The chamber is equipped with a positioning component, which has a slot. The slot has an inlet and an outlet facing different directions. The inlet faces the iron removal station. The clean hood is equipped with a docking ball head. When the clean hood docks with the clean chamber, the docking ball head engages with the slot from the inlet. When the clean hood separates from the clean chamber, the docking ball head disengages from the slot from the outlet.

7. The self-cleaning lithium battery pole piece iron removal device of claim 5, wherein, The magnet is a cylindrical magnet, and the chamber body is provided with a door for taking out and putting in the magnet on the side away from the iron removal station. The width of the door is greater than the diameter of the magnet.

8. The self-cleaning lithium battery pole piece iron removal device of claim 5, wherein, The lifting assembly includes a lifting cylinder, one end of which is pivotally connected to a mounting base, and the other end is connected to the chamber body via a floating joint. The lifting cylinder is provided with a first magnetic plate, which is located at the port in the length direction of the chamber body. When no cleaning operation is being performed, the magnet is positioned at the first magnetic plate by magnetic force.

9. The self-cleaning lithium battery pole piece iron removal device of claim 1, wherein, The cleanroom hood is equipped with a second magnetic plate. When no cleaning operation is being performed, the cleanroom hood is positioned outside the magnetic rod by the magnetic force between the second magnetic plate and the magnetic rod.

10. The self-cleaning lithium battery pole piece iron removal device of claim 1, wherein, The cleanroom hood has a C-shaped cross-section.
