  • Publication number: 20240316792
    Abstract: A vacuum gripper (10) includes a suction element (12) and a wear detection device (22) for detecting a state of wear of the suction element. The wear detection device includes a wearing section (36) which is itself subject to wear as the suction element wears in normal use; a fluid channel (24), which interacts with the wearing section in such a way that, as a result of wear of the wearing section, a flow cross-section of the fluid channel is altered and/or a fluid flow through the fluid channel is released in the first place, and a sensor device (38) for detecting a pressure in the fluid channel and/or a fluid flow through the fluid channel.
