AI Technical Summary
The existing rotary structure of the Tianche cannot meet the arrangement of various wafer boxes, and due to the large size and the lower jaw height, the size of the wafer box that the Tianche can carry is limited.
A rotating structure of a small trolley is designed, adopting a combination of a first rotating wheel, a second rotating wheel and a traction member, with the action direction parallel to the setting plane, and the traction member is driven by the driving device to realize the rotation of the trolley clamping jaws, simplify the power mechanism, and reduce the volume height.
While taking into account the rotation amplitude, the volume height of the rotating structure is reduced, allowing the Tianche clamping jaw to clamp a larger size semiconductor carrier to adapt to semiconductor carriers of different sizes and placement methods.
