Abstract

This screw driver 10 has been adapted for use with robot's quick change tooling so that it may be picked up by the robot and exchanged with other tools during the robot's operations. The vertical ball slide 12 allows the driver 10 to move independently of the robot's z axis. The proximity switch 14 allows the relative height of the driver 10 to the z axis to be known. Springs 16 are placed on shaft 18 in the back to adjust the force required on the driver 10 to move it relative to the robot's arm. The working of these components with a standard driver operation is outlined below.

Robotic Screw Driver

This screw driver 10 has been adapted for use with robot's quick change tooling so that it may be picked up by the robot and exchanged with other tools during the robot's operations. The vertical ball slide 12 allows the driver 10 to move independently of the robot's z axis. The proximity switch 14 allows the relative height of the driver 10 to the z axis to be known. Springs 16 are placed on shaft 18 in the back to adjust the force required on the driver 10 to move it relative to the robot's arm. The working of these components with a standard driver operation is outlined below.

The robotic driver 10 is picked up by the manipulator and brought over the screw site 11. The robot moves down in the z direction and the driver 10 is engaged by the force on the driver tip 20 if it is automatic. If the driver is not automatic the proximity switch 14 may be employed to turn the driver on when the robot has moved down far enough in the z direction to engage the switch. The driver used is of the "one shot" type. It will automatically turn off when it has reached the set torque. The robot may then move down in the z direction and check its position when the proximity switch has made in order to verify the screw has seated properly.
