Rotary mechanism for vacuum continuous coating production line

The invention discloses a rotary mechanism for a vacuum continuous coating production line. The rotary mechanism mainly solves the technical problems of long production line, high cost and the like of the conventional continuous processing equipment. The invention adopts the technical scheme that: the rotary mechanism comprises an upper transmission magnetic fluid, a lower transmission magnetic fluid, a rotary frame, a lower supporting flange and an upper supporting flange, wherein the upper transmission magnetic fluid and the lower transmission magnetic fluid are vertically and symmetrically arranged on the same axis; the lower part of the upper transmission magnetic fluid is provided with the upper supporting flange, and the upper part of the lower transmission magnetic fluid is symmetrically provided with the lower supporting flange; and the rotary frame is arranged between the upper supporting flange and the lower supporting flange, a lower rotating shaft is hermetically arranged in the lower transmission magnetic fluid, and the lower part of the lower rotating shaft is provided with a rotary driving device. The rotary mechanism can control two workpieces to realize 180-degree turning operation so that the workpieces return to the production line for continuous processing. The rotary mechanism is particularly suitable in the production process of the vacuum production line, and can reduce about half vacuum equipment so as to save the cost.
