The method of roll line handling trays of claim 1, wherein: in step (42), the power mechanism does not pause to always perform movement while the top plate continues to rise when reaching the end L of the roller line, and the top plate exceeds the surface height of the roller line when reaching the end L of the roller line.
4. The method of roll line handling trays of claim 1, wherein: in step (51), the tray is lowered and the power mechanism synchronously operates or the power mechanism pauses the lowering of the tray and then starts.
5. The method of roll line handling trays of claim 1, wherein: the lifting assembly comprises any one or two of a scissor assembly and a rigid chain assembly.
6. The method of roll line handling trays of claim 1, wherein: the roller is a driven wheel;
the power mechanism is arranged between the two roller lines and is a multi-stage electric push rod or a synchronous belt assembly.
7. The method of roll line handling trays of claim 6, wherein: the synchronous belt assembly comprises a synchronous belt, a synchronous belt fixing block and a synchronous belt wheel;
The synchronous belt is wound on the synchronous belt wheel; the synchronous belt fixing block is fixed on the synchronous belt, and a rolling wheel is arranged at the bottom of the synchronous belt fixing block; and the synchronous belt fixing block synchronously moves along with the synchronous belt when the synchronous belt wheel rotates.
