Automatic membrane turning machine

The invention discloses an automatic membrane turning machine which comprises a machine frame. An electric control box is arranged on the machine frame. An electric control system is arranged in the electric control box. A vertical moving mechanism is arranged on the machine frame. A rotation moving mechanism is arranged on the vertical moving mechanism transversely. A vacuum absorbing mechanism is arranged on the rotation moving mechanism. The vertical moving mechanism is connected with the electric control system. The rotation moving mechanism is connected with the electric control system. The electric control system is connected with the vacuum absorbing mechanism. A membrane storing box is arranged below the vacuum absorbing mechanism. The automatic membrane turning machine achieves automatic operation of membrane turning, achieves a safety monitoring function and is safe to operate by using a vacuum absorbing system.
