초록 ▼

A vacuum insulated glass (VIG) panel includes a first glass panel and a second glass panel spaced from the first glass panels. A spacer is disposed between the first and second glass panels. The spacer includes first and second generally opposed faces, and a plurality of sides extending therebetween. The spacer is processed using tumbling and polishing operations to preferably round all corners of the spacer and form a circular contact footprint on opposed side faces of the spacer. The spacer surface break conditions are measured during tumbling and/or polishing operations using optical flat measuring equipment. Following the polishing operation the spacer is thermally processed to strengthen the spacer.

대표청구항 ▼

1. A method comprising: cutting a spacer blank from a sheet of glass, the spacer blank having opposing first and second side faces and a plurality of sides defining a generally polygonal periphery for the side faces of the blank;polishing the spacer blank to round corners of adjoining sides around the polygonal periphery, and to round corners between the plurality of sides and the first and second faces to form the spacer with surface breaks;using an optical flat measuring device to measure the surface breaks of the opposed faces of the spacer during processing; andproviding the spacer for use between first and second glass panels of a vacuum insulated glass panel when the spacer has a desired level of surface breaks as measured via the optical flat measuring device. 2. The method according to claim 1, wherein cutting the plurality of spacer blanks includes scribing the sheet of glass to create a plurality of scribe lines in the sheet of glass, and breaking the sheet of glass along the plurality of scribe lines. 3. The method according to claim 2, wherein the plurality of scribe lines define the generally polygonal periphery of the blank. 4. The method according to claim 2, wherein breaking the sheet of glass along the plurality of scribe lines includes supporting the glass sheet on an elastomeric sheet and rolling a roller across the glass sheet in a direction perpendicular to the plurality of scribe lines. 5. The method according to claim 4, wherein breaking the sheet of glass further comprises adhering a dicing tape to a side of the glass sheet opposite the plurality of scribe lines. 6. The method according to claim 5, further comprising releasing at least a portion of the plurality of spacer blanks from the dicing tape. 7. The method according to claim 1, wherein cutting the plurality of spacer blanks includes cutting the plurality of spacer blanks using one or more of a saw, a laser, and a water jet. 8. The method according to claim 1, wherein polishing the spacer blank includes tumbling the spacer blank with a polishing compound. 9. The method according to claim 1, wherein polishing the spacer blank includes chemically etching the spacer blank. 10. The method according to claim 1, further comprising thermally polishing the spacer at an elevated temperature. 11. The method according to claim 1, further comprising chemically strengthening the spacer in an ion bath. 12. The method according to claim 1, further comprising cleaning the spacer using one or more of a solvent and a surfactant. 13. The method according to claim 1, further comprising cleaning the spacer by heating the spacer to an elevated temperature.
