This utility model discloses a semiconductor component sorting turntable, including a turntable mounted on a support platform via an annular support block on its bottom surface. Several clamping mechanisms are arranged in a circular array on the turntable surface. By arranging four clamping mechanisms in a circular array on the turntable surface to fix semiconductor components, the turntable can achieve multi-station synchronous operation with high flexibility. Depending on the size of the semiconductor component, rotating the handwheel causes the screw drive's two nut seats (one and two) to move in opposite directions, adjusting the clamping blocks (one and two) to a spacing suitable for the semiconductor component. The semiconductor component is then placed between the clamping blocks. Further rotating the handwheel causes the screw drive's two nut seats (one and two) to further drive the clamping blocks (one and two) to fix the semiconductor component, enabling the clamping mechanism to clamp and fix semiconductor components of different sizes.
