Abstract

Widespread use of robots in manufacturing environments, and the need to adapt such robots to various manufacturing operations have led to the development of robots with interchangeable grippers. The ability to change grippers is an enabling feature for the robots to perform multiple tasks. An example of the components comprising such a robot are illustrated in Figure 1, which displays a robot available from Applied Robotics Corp. Typically, the robot includes: robot arm 10, flange 12, actuator coupling 14, gripper changer 16, and gripper 20 which may be exchanged with other grippers maintained in a tool rack (not shown).

ROBOT GRIPPER MISALIGNMENT DETECTION DEVICE(Cont'd)

Widespread use of robots in manufacturing environments, and the need to adapt such robots to various manufacturing operations have led to the development of robots with interchangeable grippers. The ability to change grippers is an enabling feature for the robots to perform multiple tasks. An example of the components comprising such a robot are illustrated in Figure 1, which displays a robot available from Applied Robotics Corp. Typically, the robot includes: robot arm 10, flange 12, actuator coupling 14, gripper changer 16, and gripper 20 which may be exchanged with other grippers maintained in a tool rack (not shown).

The present disclosure is directed toward an improved misalignment detection device suitable for detecting when the gripper has been improperly deposited in the tool rack so as to prevent the robot from further trying to attach to the gripper. Accordingly, the misalignment detection device described herein is suitable for preventing damage to the gripper and/or robot. As illustrated in Figure 2, the device is comprised of two components, a gripper changer 30 and an i...
