[0001] The present invention relates to the technical field of lithium battery coating equipment design, and in particular to a battery pole piece clamping wheel assembly for double-sided coating. Background Art

[0002] In the coating process of lithium battery pole pieces, the pole pieces are often tensioned by rollers. When double-sided coating is performed, since both sides of the pole piece are coated with slurry, it is impossible to tension and support the pole piece by rollers if the slurry is not dry. Figure 1 ), after coating one side, the coating steel roller cannot be installed on the back. When the die head is coating the second side, the electrode entering the oven section will inevitably be shaken by the wind field, thereby affecting the coating quality of the second side and the coating surface density.
