A method for temporarily holding workpieces during one or more manufacturing processes, the workpieces each having a contoured surface, the method comprising:
- providing a workholding system having:
- a plurality of wireless UV light sources each having a battery and a UV source, each of the wireless UV light sources being selectively operable to provide UV illumination;
- a controller operable to wirelessly communicate with each of the plurality of wireless UV light sources so as to selectively trigger individual ones of the wireless UV light sources to provide the UV illumination;
- a plurality of workpiece shuttles each for temporarily holding one of the workpieces during the one or more manufacturing processes;
- each of the plurality of workpiece shuttles having;
- a support body having a contoured body surface complementary to the contoured surface of the workpiece, at least a portion of the contoured upper body surface formed of a transparent material and defining a bonding zone;
- the support bodying having a pocket configured for receiving one of the plurality of wireless UV light sources such that the wireless UV light source is at least partially disposed in the support body and is operable to provide the UV illumination through the transparent material to the bonding zone;
- a base attached to and supporting the support body so as to form the workpiece shuttle, the base having a plurality of zero-point locating elements configured to locate the base relative to a manufacturing workstation, the base further having a support face;
- a bond station configured to receive one of the plurality of workpiece shuttles, the bond station having a plurality of zero-point locating elements complementary to the zero-point locating elements of each of the bases, the bond station further having a plurality of workpiece locating elements;
- receiving one of the plurality of workpiece shuttles on the bond station, wherein the support body is interconnected with the base of one of the plurality of workpiece shuttles to form the workpiece shuttle prior to the receiving step;
- positioning one of the plurality of workpieces shuttles in a predefined position by the complementary zero-point locating elements of the base and bond station;
- receiving one of the workpieces on the support body with contoured surface adjacent the bonding zone;
- positioning the workpiece on one of the plurality of workpiece shuttles in a predetermined position relative to the zero-point locating elements of the base of the shuttle by the plurality of workpiece locating elements of the bond station;
- applying a UV curable workholding adhesive to the bonding zone between the contoured surface of the workpiece and the complementary body surface;
- wirelessly triggering, by the controller, the wireless UV light source that is disposed in the support body of the one of the workpiece shuttles, thereby illuminating the adhesive in the bonding zone through the transparent material with UV, and thereby curing the adhesive such that the workpiece is temporarily fixed in the predetermined position relative to the zero-point locating elements of the base of one of the plurality of workpiece shuttles;
- removing one of the plurality of workpiece shuttles, with the workpiece affixed thereto, from the bond station and moving one of the plurality of workpiece shuttles and workpiece to a first manufacturing workstation;
- performing at least one manufacturing process;
- and
- debonding the workpiece from the support body of one of the plurality of workpiece shuttles, wherein the debonding step comprises debonding without disassembly of the support body from the base of the shuttle.
