Circuit assembly device for programmably controlling¹placement force and method thereto

摘要

A robotic placement device (FIG. 1) comprises a programmable end-effector (200) for picking and placing component parts. The programmable end-effector (200) comprises a cylinder (201) having a piston (202) including a first (203) and second (208) shafts coupled together. The first shaft (203) of the piston is larger than the second shaft (208). A controller (102) controls a pressure applied to the cylinder (201) and the piston (202) including the first (203) and second (208) shafts of the programmable end-effector (200) establishes a predetermined placement force at the programmable end-effector (200) while placing component parts. A control circuit 118 senses the pressure and in response thereto generates a signal. A processor 108 coupled to the controller (102) processes the signal and in response thereto varying the pressure for maintaining a substantially constant placement force at the programmable end-effector (200) while the programmable end-effector (200) moves vertically.
