Claim 0:
1. A semiconductor wafer cassette roller type transportation structure system, comprising a roller type transportation structure body, a rotating transportation structure body, and a lateral movement transportation structure body, wherein:
the roller type transportation structure body includes a left supporting frame, a right supporting frame, a plurality of large rollers, a plurality of small rollers, an elongated cover, an activation rod, and a driving belt;
the supporting frame is shaped as a U and includes a top U-shaped groove, a bottom U-shaped groove, an interconnection surface interconnecting the top U-shaped groove and the bottom U-shaped groove, a plurality of first apertures provided on the interconnection surface with the large rollers provided therein respectively, a plurality of second apertures provided on the interconnection surface with the small rollers provided therein respectively, and a hole provided through the interconnection surface;
a driving wheel of the activation rod passes through the hole;
each of the plurality of large rollers includes a hollow first main body, a screw inserted into the first main body, a plurality of first bearings, a first roller, and a connecting rod driven through the first bearings and the first roller to be fastened by the screw in the first main body; and
each of the plurality of small rollers includes a hollow second main body, a second bearing, a second roller, and a screw driven through the second main body and the second bearing to be fastened in the second roller;
the elongated cover includes two screw holes at either end;
the activation rod including a driving motor, a motor shaft driven by the driving motor, a bearing member put on an open end of the motor shaft; and the driving belt for rotating the large rollers, the small rollers, and the driving wheel;
wherein the roller type transportation structure body includes a roller transportation structure;
the roller transportation structure includes a first outer covering member at a left side of the left supporting frame, a portion of the plurality of large rollers at an upper portion of the left supporting frame, a driving motor at a lower portion of the left supporting frame, a motor shaft extending out of the driving motor to connect to the right supporting frame, a second outer covering member at a right side of the right supporting frame, another portion of the plurality of large rollers at an upper portion of the right supporting frame, and a plurality of connecting rods provided between the left supporting frame and the right supporting frame;
the rotating transportation structure body includes a rotating seat and a rotating motor both provided under the roller transportation structure;
the lateral movement transportation structure body includes a lateral movement structure, a roller transportation structure, and a driving link in the lateral movement structure for laterally moving the wafer cassette in cooperation with the roller transportation structure; and
in response to the roller type transportation structure body transporting the wafer cassette, the rotating transportation structure body rotates to change a movement direction of the wafer cassette, and the lateral movement transportation structure body transports the wafer cassette along a lateral movement direction.
