Claim:
1. A vibration assistant polishing module, adapted for polishing a workpiece, comprising: a polishing disk, disposed for enabling the same to be rotatable; a workpiece carrier tray, for carrying the workpiece while enabling a finish surface of the workpiece to face toward the polishing disk; a linear guide way mechanism, composed of a slide, a guide seat and a guide rod in a manner that the slide is pivotally coupled to a surface of the workpiece carrier tray opposite to another surface where the workpiece is disposed, and is embedded in the guide seat, while enabling the guide rod to be disposed on the guide seat; a linkage, having a first end and an opposite second end while allowing the first end to be pivotally coupled to the slide; a motor, having a power shaft; and an adjustable eccentricity mechanism, further comprising: a base which is connected to the power shaft of the motor, and is coupled to the second end of the linkage via a pivot shaft while allowing the pivot shaft to be eccentrically disposed to the power shaft; wherein, the power shaft drives the base to rotate so as to bring along the linkage to swing eccentrically, power provided from the power shaft is transmitted to the slide via the linkage for enabling the slide to move linearly in a direction parallel to a first direction according to a limitation from guide seat, and thereby a low frequency vibration with a horizontal radial amplitude is generated on the workpiece carrier tray, while simultaneously the low frequency vibration is generated on the surface of the workpiece which is engaged with the polishing disk.
