Dual stage positioning and switching system

A dual stage positioning and switching system, comprising:

• a base;
• two object stage positioning units, disposed on said base and including a first object stage positioning unit for a first workstation and a second object stage positioning unit for a second workstation;
• and
• a transitional object stage connector for transitional use during a switching process,
• each of the two object stage positioning units comprising:
• at least a supporting structure including an object stage and an object stage connector, said object stage being movable relative to said object stage connector,
• an X-direction guide bar,
• a Y-direction guide bar,
• a motion positioning detector, and
• a driver connecting to said object stage connector and driving said object stage connector to move along said X-direction guide bar,
• said X-direction guide bar being positioned on and movable along said Y-direction guide bar, wherein
• the transitional object stage connector is fixed at the center of said Y-direction guide bar located on one side of said base, and
• the transitional object stage connector is configured to receive the object stage of one of the two object stage positioning units and then transfer, after the object stage of the other of the two object stage positioning units is transferred to the object stage connector of the one of the two object stage positioning units, the object stage of the one of the two object stage positioning units to the object stage connector of the other of the two object stage positioning units.
