Method for producing a join connection between sections in a production assembly

摘要

Producing an assembled component comprises taking two parts from a delivery site near a conveyor, setting the parts in a mutually oriented position on the conveyor, transporting the parts to an assembling station, stopping the conveyor, moving the parts to a delivery position by means of a vertical positioning device, positioning the parts relative to each other, clamping and assembling the parts to form the assembled component, setting the component on a conveyor and transporting it away. Independent claims are also included for: (1) transport system for delivering parts to an assembling station, comprising a conveyor with supports comprising a receptacle with a positioning device for holding a part during transport, guide surfaces on either side of the parts, and two seating surfaces for at least one of the supported parts; (2) fabricating unit for producing an assembled component, comprising an assembling station, a transport system as above, and a clamping system and a vertical positioning device separate from the conveyor; (3) fabricating an assembled component using a fabricating system comprising several fabricating units as above, each with a laser welding head, where the welding heads are operated alternately from a single energy source according to the transport and assembly cycle; (4) fabricating system as above; (5) welding station comprising a drive unit for positioning laser welding heads equipped with mirrors and focussing devices, where the welding heads have a pivotable base supplied with energy through a flexible lead; (6) positioning and checking the quality of a part to be processed in an assembling station, where the part is positioned between two cooperating clamping tools that are displaced from an initial position to a clamping position by an electronically controlled linear drive, where the clamping force and the tool travel path are compared with target values in an electronic analyzer, the target values having tolerance fields with lower and upper limits, and parts with actual clamping force and/or tool travel path values falling outside the tolerane limits are rejected; (7) joining together two parts in an assembling station using a positioning and quality checking method as above; (8) fabricating unit for producing an assembled component from two parts, comprising two clamping tools as above and a third clamping tool for holding the two parts together; (9) assembling parts in an assembling station as above in which the clamping force is produced by an outer part acting on an inner part; (10) assembling parts in an assembling station as above in which the parts are held in place and joined together when the target clamping force and/or tool travel path is attained.
