Abstract:
1. A substrate-transporting device, comprising: a base; a shaft unit having a supporting shaft and a shaft base, wherein a first end of said supporting shaft is pivotally connected to said shaft base mounted on said base to support and control rotation of said supporting shaft; and a substrate carrier unit fixedly mounted at a second end of said supporting shaft and supported by said supporting shaft, comprising: a bottom carrier seat connected to said supporting shaft; a plurality of first supporting components mounted on a surface of said bottom carrier seat; a top carrier seat mounted opposed to the side of said bottom carrier seat where said supporting shaft is located; a plurality of second supporting components mounted on an inner side of said top carrier seat; and at least a retractable component sandwiched between said top carrier seat and said bottom carrier seat; wherein a plurality of vacuum suction nozzles are disposed on a surface of said top carrier seat, and said retractable component selectively adjusts the distance between said top carrier seat and said bottom carrier seat so that said first supporting components are located between said top carrier seat and said bottom carrier seat and that said first supporting components project out of the surface of said top carrier seat to support a substrate; wherein said shaft base is capable of indirectly controlling a tilted angle of said substrate carrier unit by controlling rotation of said supporting shaft, and said top carrier seat having a vacuum slit disposed on the surface of said top carrier seat relative to the periphery of said substrate.
