System for leak testing industrial components

Abstract

A system for leak testing industrial components, such as engine blocks, is disclosed and includes a conveyor system for transporting the engine components to and from a test area having a support surface. A robot is operable in the test area and includes a manipulator which engages and moves the industrial components. At least two leak test units are provided where each leak test unit includes a shuttle for receiving the industrial component from the robot and thereafter subjecting that industrial component to a leak test. Each leak test unit then generates a failure output signal in response to a failed leak test on the industrial component. Each leak test unit is movably mounted to the test area support surface between an operable position and an inoperable position. In its operable position the leak test unit is positioned in the test area to receive the industrial components from the robot and perform the leak test. Conversely, in its retracted position, the leak test unit is positioned outside of the test area for maintenance, repair or the like. A robot control circuit controls the movement of the industrial components by the robot between the conveyor system and one or more of the selected leak test units in response to at least one control factor, such as a failure output from one of the leak test units.
