Optionally, in the embodiment, the base material 10 can be a diaphragm, but is not limited thereto, and in other embodiments, the base material 10 can also be a pole piece or other articles.

[0048] The existing coating device needs to drive the traction roller to rotate by a driving motor when coating the base material 10, so that the traction roller traction the base material 10 to move, so as to complete the coating of the base material 10. However, in the process of traction of the base material 10 by the traction roller, the base material 10 and the traction roller are prone to slipping, and the base material 10 cannot be reliably and uniformly transported.
