[0025] [Figure 1] FIG. 2 is a schematic diagram of an exemplary flexible vacuum assembly fitting. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] 1, a flexible vacuum assembly fixture 10 is illustrated. A base 12 supports at least one arm 14. The base 12 can be configured to adjust in multiple axes. The base 12 can be configured in a variety of orientations. The base 12 couples to a platform 16. The platform 16 is configured as a rigid structure to support the base 12.

[0027] The fixture 10 shown in FIG. 1 has a set of three arms 14. It is contemplated that a different number of arms 14 can be utilized. The arms 14 can be an assembly of multiple ball and socket components 18 coupled in series. The multiple ball and socket components 18 can pivot by use of a ball inserted into a mating socket in each of the serially successive components. The ball and socket components 18 can include a predetermined friction / resistance that enables the components 18 to be manipulated relative to one another while providing sufficient rigidity to remain stationary to support the component 20. The length and weight support capacity of the arms 14 can be configured to be scalable depending on the size, weight, and shape of the component 20 to be supported. The arms 14 can be variable in length as well as thickness, ball and socket resistance, etc.

[0028] A suction cup fitting 22 can be attached to the arm 14 at a distal end 24 having a location distal from the base 12. The suction cup fitting 22 can be configured to create a vacuum tight coupling to an exterior surface 28 of the component 20 via 26. The suction cup 26 can removably adhere the suction cup fitting 22 to the exterior surface 28. The suction cup fitting 22 can also include a non-marring, tacky material, or adhesive properties to enable sufficient contact support of the exterior surface 28 of the component 20. The suction cup fitting 22 can be enabled by use of a vacuum generator (vacuum pump) 30 in fluid communication with the suction cup fitting 22 via a vacuum tube 32. The arm 14 can be manipulated as necessary for the desired location and orientation of the component 20, either before or after a vacuum tight coupling is established between the component 20 and the suction cup 26.

[0029] The vacuum demand switch 34 can be fluidly coupled to the vacuum generator 30 to support sufficient vacuum suction. The suction cup fitting 22 can include a body 36 having a receptacle socket 38 configured to attach to a corresponding ball on the distal end 24. The body 36 also includes a vacuum line receptacle 40 configured to attach to the vacuum tube 32. The suction cup 26 is connected to the body 36 opposite the receptacle socket 38. The suction cup 26 extends from the body 36 and is in fluid communication with the receptacle 40.

[0030] A manifold 42 may be utilized to distribute the vacuum tubes 32. The suction cup fittings 22 may be scaled in size. The suction cup fittings 22 may be scalable, removable, and replaceable to allow multiple sizes to fit multiple weights, sizes, and shapes of components 20.

[0031] To protect against electrostatic discharge to components 20 that are sensitive to such hazards, a grounding feature 44 can be electrically coupled to the suction cup fitting 22. The grounding feature 44 can be electrically coupled through conductive properties of the suction cup fitting 22, arm 14, base 12, vacuum tube 32, and platform 16 for ultimate ground, as shown. In an exemplary embodiment, a conductive wire or cable 46 can be provided.

[0032] Technical advantages of the disclosed flexible vacuum assembly fittings include the ability to tailor the fitting to multiple, non-common geometries.

[0033] Another technical advantage of the disclosed flexible vacuum assembly fixture includes the ability to attach to components via vacuum suction.

[0034] Another technical advantage of the disclosed flexible vacuum assembly fitting includes flexibility of the articulating base, which provides multiple degrees of freedom of movement.

[0035] Another technical advantage of the disclosed flexible vacuum assembly fixture includes multiple articulated arms for capturing and supporting components.

[0036] Another technical advantage of the disclosed flexible vacuum assembly fixture includes a scalable device that can accommodate a wide variety of component sizes, weights, and geometries.

[0037] Another technical advantage of the disclosed flexible vacuum assembly fixture includes a path to ground feature that provides effective electrostatic discharge protection.

[0038] Another technical advantage of the disclosed flexible vacuum assembly fixture includes a non-marring suction cup design to protect component surfaces.
