Abstract:
Shape Memory Alloy (SMA) wires are a promising actuation technology for industrial applications due to their high energy density. These wires contract when heated, typically via an applied current, as a consequence of a phase transformation between martensite (cooled wire) and austenite (heated wire). The first prototype of an SMA-actuated vacuum gripper was presented at the Actuator14 conference. The focus of this paper is on the development of a second generation prototype of an SMA-actuated vacuum gripper that does not require continuous activation during gripping. For evaluation and validation of the gripper system, a test rig is used to measure the created vacuum with a pressure sensor and the deflected membrane with a laser displacement
sensor during operation. Different experiments take a look at the vacuum quality over time, lifting forces and repeatability. The paper ends with an outlook on future work and a discussion of possible application scenarios.
