Problems solved by technology

Many processes are required in the production process of lithium electronics. After coating, the battery pole piece needs to be shaped by a die-cutting machine, and the battery pole piece is cut into a fixed shape of the battery. The coil material discharge of the pole piece is generally controlled by a photoelectric switch. , automatically and synchronously unwinding according to the forming length, the pole piece coil is then sent to the conveyor belt, and the pole piece coil is in contact with the conveyor belt. Since the conveyor belt rotates around the die-cutting machine up and down, during the rotation process, it will inevitably come into contact with Dust, or other impurities fall on the conveyor belt. When the pole piece coil is in contact with the conveyor belt, the impurities on the conveyor belt will be adsorbed on the battery pole piece, which will affect the quality of the battery pole piece, thereby affecting the quality of the battery product
