Abstract
A blade assembly is connected to a robot arm for transmission of semiconductor chips and includes a blade, a top cover, a bottom cover, and two pivot units each including a pivot arm, a first bearing, and a second bearing. Thus, the positioning flange of the mounting ring of the pivot arm is sandwiched between the first bearing and the second bearing and the inner washer is sandwiched between the inner ring of the first bearing and the inner ring of the second bearing, thereby preventing the first bearing from pressing and jamming the second bearing due to a pressing action of the urging cap, so that the pivot arm is pivotable smoothly and stably.

A blade assembly, comprising:
- a blade;
- a top cover mounted on the blade;
- a bottom cover mounted on the blade and combined with the top cover;
- two pivot units each pivotally mounted between the top cover and the bottom cover and each including a pivot arm pivotally mounted between the top cover and the bottom cover and having an end formed with a mounting ring rotatably mounted on a respective one of the two bearing seats of the top cover, a first bearing mounted between the top cover and the mounting ring of the pivot arm, and a second bearing mounted on the mounting ring of the pivot arm;
- wherein the mounting ring of the pivot arm of each of the two pivot units has an inner wall formed with a positioning flange rested on and located between the first bearing and the second bearing.
