A conduit system for conducting activation power to a tool module of a reconfigurable end-effector attachable to a robotic arm includes a fixed conduit portion conforming to a first portion of the reconfigurable end-effector including a master boom and a first portion of a rotatable guide rail. The conduit system includes a translatable conduit portion translatably connected to a second portion of the reconfigurable end-effector including a second lateral portion of the rotatable guide rail and a branch. The conduit system includes a rotatable portion connected between an end of the translatable conduit portion and a workpiece interface tool of the tool module.

An end-of-arm tool having a workpiece interface tool is attachable to an articulable robotic arm. The end-of-arm tool can be configured by engaging an adjustable modular unit including a swing arm, a cylinder, and a workpiece interface tool to a rail element of the end-of-arm tool. The adjustable modular unit machine-slides in the rail element to a preferred x-axis position, machine-pivots to a preferred angular orientation, and machine-extends along a longitudinal axis of the cylinder to a preferred z-axis position, and machine-rotates to a preferred rotational angle about the z-axis.

A configurable end-of-arm tool attachable to an articulable robotic arm is described. The end-of-arm tool comprises a rail element, a machine-adjustable swing arm, a machine-adjustable extendable shaft attached to the swing arm. A machine-adjustable rotator set is attached to the extendable shaft, and a workpiece interface tool is attached to the extendable shaft. The swing arm, the extendable shaft, and the rotator set are machine-adjustable to place the workpiece interface tool at a predetermined position.

The end-effector includes an articulating frame mounted on an indexable boom. Tool modules mount on the end-effector and connect to a workpiece. Each tool module includes a flexible dress package including a cable carrier. A channel rail is supported by the end-effector frame and guides the cable carrier. A setup tool and associated process can reconfigure the positions of the tool modules and the frame and boom of the end-effector.

An adjustable length cylinder assembly includes a housing and a piston reciprocably mounted within the housing for movement between an extended position and a retracted position. The piston defines first and second hydraulic fluid chambers of differing cross-sectional area on opposite sides of the piston. An accumulator is housed within one of the housing and the piston. Channels communicate hydraulic fluid the first and second chambers and the accumulator during the movement of the piston. A valve member is concentric with the piston and accumulator and rotatable between a first rotary position in which the channels are open so that fluid can be transferred between the chambers to allow retracting and extending movement of the piston and a second rotary position in which the channels are closed so that fluid cannot be transferred and the piston is locked against retracting and extending movement.

A bayonet collet pickup tool includes a collet chuck having a collet portion including a bore disposed therein. A collet is held in the bore and is operable therein. A bayonet cap is mounted to an outer surface of the collet chuck proximate the bore. The bayonet cap includes a tubular socket concentric with the bore, at least one pair of diametrically opposed linear slots adjacent the socket, and a circular ledge adjacent the socket and perpendicular to the slots. A part including a shaft and at least one pair of diametrically opposed pins projecting from the shaft is receivable in the bayonet cap and the bore. Rotating the collet chuck while the pins are level with the ledge and then closing the collet releasably retains the part in the tool.

A reconfigurable tool module for an end-effector includes an adjustable-height housing attached to a swing arm. The adjustable-height housing includes a valve spool and a flow path terminating at a workpiece interface tool. The valve spool is configured to interrupt the flow path when the adjustable-height housing is in a first position. The valve spool is configured to open the flow path when the adjustable-height housing moves away from the first position.

A method and apparatus for assembling a fuel cell stack is disclosed, wherein the apparatus includes a plurality of dunnage cassettes adapted to cooperate with a plurality of containers, a fixture, and an assembly device to simultaneously assemble a plurality of membrane electrode assemblies together with a plurality of bipolar plates.
摘要:
An integrated locking assembly that includes a linear locking mechanism and a rotary locking mechanism. The linear locking mechanism employs opposing locking plates having aligned bores that can lock onto a rod extending through the bores. The rotary locking mechanism includes rollers positioned between a housing and a cam where the rollers are wedged between the housing and the cam to lock the rotary locking mechanism and are positioned in an open position between the housing and the cam to unlock the rotary locking mechanism.
