Adjustment mechanism, pick-and-place system, and operation method thereof

An adjustment mechanism, configured to be mounted on a movement mechanism, comprising:

• a first coupling component, configured to be mounted on the movement mechanism;
• a second coupling component, movably disposed on the first coupling component;
• and
• a driving assembly, comprising:
• a shaft, rotatably disposed on the first coupling component;
• a first pushing component, rotatable with the shaft and in contact with the first coupling component or the second coupling component for forcing the first coupling component and the second coupling component to move relative to each other;
• and
• a rotation-driving component, connected to the shaft and configured to rotate the shaft relative to the first coupling component.

An operating method of a pick-and-place system, comprising:

• using a clamping mechanism to pick up an object to a top of another object;
• moving the clamping mechanism a first distance along a first direction to partially engage the object with the another object, wherein the first distance is smaller than a depth that the object is fully-engaged with the another object;
• moving the clamping mechanism along a second direction which is perpendicular to the first direction to force the object to move the another object along the second direction;
• and
• moving the clamping mechanism a second distance along the first direction to fully-engage the object with the another object, wherein a sum of the first distance and the second distance is substantially equal to the depth that the object is fully-engaged with the another object.
