Method for transporting workpiece carriers on an assembly line, workpiece carrier and assembly unit

摘要

The transport of work carriers on an assembly line is performed by the use of novel linear motors in which the primary part has both solenoids and permanent magnets and in which the secondary part has no permanent magnets of its own. By the provision of a magnetically soft plate, a work carrier has uniformly spaced clearances with respect to the secondary part and can be moved by the suitably arranged primary part. On an assembly line, it can be provided that the primary parts supplement the unction of an existing transporting bet. It may also be provided that a transporting belt is completely replaced by such primary parts.
