An industrial robot arm assembly line application is not selected from a reach circle. Fixture spacing, tool offsets and the orientations required at pick and place change wrist moments and inertia. This page explains how those operating conditions feed the RFQ. Complete welding cells or palletizing cells remain outside this family unless they are written as a different project. Compare inquiry options after the line context is named.
Upstream of the arm, parts may arrive nested, on a pallet or from a machine door. Changing SKUs can change nest height and grip face. List the tallest stack, the longest tool offset and whether a tool-change is required. Wrist moments follow from those offsets; two parts of equal mass are not equivalent if one is held far from the flange. Compressed air demand for a new gripper should be stated separately from the arm’s electrical connected load.
During changeover, the PLC interface must know which program, which TCP and which interlock set is active. Ask the bidder to show how an interrupted machine-loading cycle is recovered after a SKU swap without leaving the adjacent machine in an unknown state. Positioning tolerance at the new fixture is a checked value, not a copy of repeatability from a datasheet. Duty cycle after changeover includes the first-good-piece check.
Downstream fixtures, jigs or conveyors may need different release heights. The application affects industrial robot arm assembly line selection because a wrist that can reach a point may still fail the required orientation there. Include service positions and tool-change access in the layout. Cycle time should count unsuccessful picks during the first accepted run after changeover.
