Loading device having suction assemblies with adjustable interspaces thereamong

摘要

A loading device of a robot includes a frame, a first pneumatic cylinder and a first pulley member mounted on a top face of the frame, a second pneumatic cylinder and a second pulley member mounted on a bottom face of the frame, first and second suction assemblies coupled to the first pneumatic cylinder and the first pulley member, third and fourth suction assemblies coupled to the second pneumatic cylinder and the second pulley member, and a fifth suction assembly secured to a middle of the frame. Interspaces among the first to fifth suction assemblies are adjustable by activating the first and second pneumatic cylinder to extend or retract pistons thereof.

1. A loading device of a robot comprising:
a frame; a first pneumatic cylinder fixed to the frame and having an extendable and retractable first piston; a first pulley member fixed to the frame and having two first pulley wheels and a first belt surrounding and engaging with the two first pulley wheels; a first suction assembly, having an end coupling with the first piston and a first section of the first belt and another end extending from the frame; and a second suction assembly having an end coupled to a second section of the first belt and another end extending from the frame, wherein each of the another ends of the first and second suction assemblies having at least a suction pad thereon for moving a workpiece from a site to another site by vacuum force; wherein when the first piston is extended, the first and second suction assemblies move away from each other to increase a gap formed therebetween, and when the first piston is retracted, the first and second suction assemblies move toward each other to decrease the gap formed therebetween.
