Abstract: A vacuum device for a material handling system includes a vacuum device body and a sealing element. The vacuum device body has a vacuum passageway in which a vacuum is generated in response to activation of a pressurized air supply that forces pressurized air through a venturi device. The sealing element moves to a sealing position to substantially seal the vacuum passageway when the air supply is activated, and is urged toward the sealing position via pressurized air that is diverted from an inlet of the vacuum device to the sealing element. The sealing element moves to substantially vent the vacuum passageway when the air supply is deactivated. The vacuum passageway may be in fluid communication with vacuum cup, which seals against the object when the sealing element is at the sealing position and the vacuum generating device generates at least a partial vacuum in the vacuum passageway.

Abstract: A camera system and associated method for aligning a component with a footprint on a PCB including: a housing having a first side and a second side opposite to the first side; a first image sensor positioned on the first side of the housing and pointing to a first direction away from the housing to capture an image of the component and generating a first image signal, wherein the first image sensor includes a first lens assembly without a prism; a second image sensor positioned on the second side of the housing and aligned with the first image sensor pointing to a second direction opposite to the first direction to capture an image of the footprint on the PCB and generating a second image signal, wherein the second image sensor includes a second lens assembly without a prism; a mixing circuit for mixing the first image signal with the second image signal and generating a mixed image signal; and a processor for processing the mixed image signal and displaying a superimposed image of the component and the footp

Abstract: An electric cylinder has a cylinder housing and a clamping assembly in the cylinder housing. An electric motor assembly is coupled with the clamping assembly to drive the clamping assembly between a first and second position. The electric motor assembly has an electric motor with a rotary output. The clamping assembly has a drive pulley assembly coupled with the rotary output. A lead screw is rotatably coupled with the drive pulley for axial movement. The lead screw moves between the first and second positions. A compliance coupling is positioned between the lead screw and the drive pulley. The compliance coupling is axially movable in the pulley assembly for absorbing shock when the piston assembly encounters a stop.
