This invention proposes an integrated vacuum pumping system for the exterior of a vacuum evaporation machine, comprising a coarse pumping pipe and a fine pumping pipe. A first three-way pipe and the fine pumping pipe are connected by a telescopic motor that drives the valve cover to rise and fall, enabling rapid switching between the coarse and fine pumping lines and avoiding vacuum fluctuations. Under the precise pressure control of the telescopic motor, the valve cover maintains uniform contact pressure on the sealing surface. The transition pipe directly connects the coarse and fine pumping pipes, eliminating flow channel redundancy in traditional multi-valve systems and reducing gas flow resistance. The telescopic motor is linked with a vacuum sensor to automatically switch the pumping mode based on the cavity pressure threshold, avoiding errors caused by manual intervention. The integrated three-way pipe reduces external connecting components, shrinks the equipment size, and lowers manufacturing costs and maintenance complexity.
