Abstract

This arrangement provides the additional capability of a power tool, such as a screwdriver, without the necessity of costly additional tool holders or tool changers. Many applications for robots include the capability of picking up a part and inserting or placing the part where it is supposed to go. The part often requires an additional function, such as attachment by screws. To accomplish the screwing function automatically by the same robot, a change of end effector is necessary. This change of tooling function is costly, but more importantly, it slows the assembly operation considerably. This problem can be overcome by using a separate robot to perform the screwing function.

Automatic Screwdriver to Increase Robot Capability

This arrangement provides the additional capability of a power tool, such as a screwdriver, without the necessity of costly additional tool holders or tool changers. Many applications for robots include the capability of picking up a part and inserting or placing the part where it is supposed to go. The part often requires an additional function, such as attachment by screws. To accomplish the screwing function automatically by the same robot, a change of end effector is necessary. This change of tooling function is costly, but more importantly, it slows the assembly operation considerably. This problem can be overcome by using a separate robot to perform the screwing function. The above problems are solved by utilizing a power screwdriver attached permanently to the robot adjacent the end effector so that the programming can switch from the gripper operation or other end effector operation to the power screwing operation. An air- operated screwdriver 10, having automatic screw feeding through a screw feed line 13, is attached to the head of the robot adjacent to the gripper and oriented vertically therewith so as to be readily available to perform the screwing. The screwdriver is attached to the head via a mounting bracket 12 and appropriate bolts, as shown in the figure. The robot can be used as an automated power screwdriver or as a component placement device using the gripper 14 followed by attachment of the...
