The coating device further includes an electric control device (not shown), and the conveying mechanism 300, the coating roller driving mechanism 500, the material receiving frame 600, the positioning roller driving mechanism 710, the slurry mechanism 800, and the roller cleaning mechanism 900 are all electrically connected to the electric control device. In this embodiment, the electric control device may be set by using a PLC or an integrated chip according to actual production needs, and since the electric control device belongs to a technology that is technically formed and mature in the prior art, the principle of how to control the coating device by the electric control device should be well known and mastered by those skilled in the art, and thus the control principle of the invention is not described herein again

The rest of this embodiment is the same as the first embodiment, and the unexplained features in this embodiment are explained by the first embodiment, which is not described herein again.

The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the present invention pertains, the architecture form can be flexible and varied without departing from the concept of the present invention, and a series of products can be derived. But rather a number of simple derivations or substitutions are made which are to be considered as falling within the scope of the invention as defined by the appended claims.
