Quick acting NC three axes gripping system for equipping PCBs - using toothed racks for transmitting force at Z and B axes and belt drive for transmitting rotational force about axis C

摘要

The part (1) can grip different components numerically controlled about the B axis. A newly developed non-play adjustable three point Z axis positioning is introduced and a newly constructed current collector is provided with a special cable lead-in for the B axis stepper motor (3). The construction is produced using light mateirals pref. aluminium or thin walled fine steel components. The gripping jaws are operated by mean sof the stepper motor (3) and the a rack and pinion drive. The current supply for the gripper stepper motor and the associated reference switch takes place by means of a rotor and a stator at the top side of the Z axis shaft. The cable lead-in for the gripper motor is led through the bored Z axis shaft, whereby the gripper assembly drives with the rotor across a connecting tube. USE/ADVANTAGE - For equipping PCBs. Very high speeds can be reached up to 110 m per min. Stepper motor (2) can give very small steps for C axis drive.
