Assembly apparatus
View Patent ↗An assembly apparatus for assembling components including a work surface, a laser projector, a computer controlling the laser projector to protect a laser image on the work surface, and an ejector lifting a completed assembly from the work surface having a retro-reflective surface within a field of view of the laser projector when the ejector is lifted, such that the laser projector scans the retro-reflective surface and the computer determines at least one of the number of completed assemblies made and the time required to make the assembly.
1. An apparatus for assembling components of an assembly, comprising:
a work surface for receiving components of an assembly;
a laser projector for projecting a laser image on said work surface;
a computer controlling said laser projector to project a laser image on said work surface for assembly of the components; and
an ejector lifting a completed assembly from said work surface having a retro-reflective surface in a field of view of said laser projector when said ejector is lifted, whereby said laser projector scans said retro-reflective surface of said ejector and said computer determining at least one of the number of completed assemblies made and the time required to make a completed assembly.
2. The apparatus as defined in claim 1 , wherein said ejector is an elongated fluid-actuated ejector having a retro-reflective upper surface.
3. The apparatus as defined in claim 1 , wherein said work surface is horizontal and said laser projector is suspended above said horizontal work surface.
4. The apparatus as defined in claim 1 , wherein said work surface includes a plurality of elongated ejector channels and said ejector is a fluid-actuated ejector located within one of said elongated ejector channels.
5. The apparatus as defined in claim 1 , wherein the assembly is a truss, said work surface is a surface of a table and said laser projector is located above said table.
6. The apparatus as defined in claim 5 , wherein said table includes a plurality of elongated ejector channels and said ejectors are located within said ejector channels each having a retro-reflective upper surface.
7. An apparatus for assembling a truss, comprising:
a work table having a work surface for assembling components of a truss;
a laser projector mounted over said work surface for projecting a laser image on said work surface;
a computer controlling said laser projector to project a laser image on said work surface for assembly of a truss; and
a plurality of ejectors in said table lifting an assembled truss from said table, each ejector having a retro-reflective surface within a field of view of said laser projector, whereby said laser projector scanned said retro-reflective surface of said ejectors upon removal of an assembled truss and said computer determines at least one of the number of assembled trusses made and the time required to make a truss.
8. The apparatus as defined in claim 7 , wherein said work table includes a plurality of spaced elongated ejector channels each having an ejector mounted therein.
9. The apparatus as defined in claim 7 , wherein said ejectors are fluid-actuated ejectors each having a retro-reflective upper surface.
10. The apparatus as defined in claim 7 , wherein said ejectors are fluid-actuated to lift an assembled truss and said retro-reflective surface is on an upper surface of said ejectors within a field of view of said laser projector when said ejectors are raised.
