Pneumatic lens turn-over device and lens polishing equipment

The utility model discloses a pneumatic type lens turn-over device and lens polishing equipment, which comprise a suction cup mechanism and a clamp mechanism used for clamping a turned lens, the suction cup mechanism is rotatably connected with a pneumatic component A through a swing arm, and the pneumatic component A is used for controlling the suction cup mechanism to turn over. A pneumatic assembly B used for controlling the clamp mechanism to clamp is arranged beside the pneumatic assembly A. The pneumatic assembly B and the clamp mechanism are movably arranged, and the clamp mechanism and the suction cup mechanism are synchronously arranged in a matched mode through the pneumatic assembly B and the pneumatic assembly A. According to the utility model, the lens is turned over in a very short time under the action of instantaneous rotation of the pneumatic assembly A, the efficiency of turning over the lens is improved, the risk that the lens falls off and is damaged during turning over is avoided, and the
