The utility model relates to the technical field of plug-in machines, in particular to a multi-
station alternating
station which comprises a mounting frame, the mounting frame comprises a vertical mounting frame and a horizontal mounting frame, a rotating mechanism is arranged on the vertical mounting frame, a transmission mechanism is arranged on the horizontal mounting frame, and the transmission mechanism is provided with a transmission
assembly and is arranged at one end of the rotating mechanism. The transmission mechanism is connected to the clamping mechanism, the
visual detection mechanism is arranged on the clamping mechanism in a sleeving mode for
visual detection, the clamping mechanism is driven to rotate, ascend and descend for clamping through the rotating mechanism and the transmission mechanism, the transmission mechanism is limited through the transmission limiting bearing, and therefore the clamping mechanism can synchronously ascend and descend, ascend and descend independently or ascend and descend in a staggered mode. And the transmission mechanism is provided with an air
pipe connector, ventilation is conducted on a ventilation hole of a transmission lead screw, so that the clamping mechanism conducts clamping, the clamping mechanism is provided with a
visual detection mechanism, then the clamping precision is improved, abrasion is reduced, and practicability is high.
