Abstract:
A robot blade system for moving substrates into and out of a chamber through an opening, the robot blade system comprising:a first robot blade for supporting a first substrate;a second robot blade disposed generally above and spaced from the first robot blade by a small distance for supporting a second substrate;a first robot arm coupled to the first robot blade for moving the first substrate and at least a portion of the first robot blade through the opening into the chamber and moving the first substrate and the first robot blade out of the chamber; anda second robot arm coupled to the second robot blade for moving the second substrate and at least a portion of the second robot blade through the opening into the chamber and moving the second substrate and the second robot blade out of the chamber, the second robot arm being independently movable from the first robot arm,wherein each robot arm comprises a connecting link, a bracket coupled between the first and second drive shafts spaced from one another, a first parallel link having a first end pivotally coupled to a first point on the first robot blade and a second end pivotally coupled to a first point on the connecting link, a second parallel link generally parallel to the first parallel link and having a first end pivotally coupled to a second point on the first robot blade spaced from the first point and a second end pivotally coupled to a second point on the connecting link spaced from the second point, a third parallel link having a first end pivotally coupled to the first drive shaft and a second end pivotally coupled to the first point on the connecting link, and a fourth parallel link generally parallel to the third parallel link and having a first end, pivotally coupled to the second drive shaft and a second end pivotally coupled to the second point on the connecting link.
