Abstract

An apparatus for cold-shaping a glass sheet that includes: a plurality of vacuum chucks configured within a moveable table; a first automated pick mechanism proximate the table; an automated dispensing mechanism proximate the table; and a pressing apparatus. The first pick mechanism is configured to shape a glass sheet onto one of the chucks. The dispensing mechanism is configured to dispense a curable adhesive onto the glass sheet or a frame. One of the first pick mechanism and the dispensing mechanism is configured to position the frame onto the glass sheet such that the adhesive is disposed between the glass sheet and the frame. The pressing apparatus is configured to press the frame and the adhesive onto the glass sheet to define a finished glass sheet assembly. The glass sheet is bendable at ambient temperature. Methods for cold-shaping a glass sheet are also included in the disclosure.

First claim

What is claimed is:

1. An apparatus for cold-shaping a glass sheet, comprising:
a plurality of vacuum chucks configured within a moveable table;
a first automated pick mechanism proximate the table;
an automated dispensing mechanism proximate the table; and
a pressing apparatus,
wherein the first pick mechanism is configured to shape a glass sheet onto one of the chucks,
wherein the dispensing mechanism is configured to dispense a curable adhesive onto the glass sheet or a frame,
wherein one of the first pick mechanism and the dispensing mechanism is configured to position the frame onto the glass sheet such that the adhesive is disposed between the glass sheet and the frame,
wherein the pressing apparatus is configured to press the frame and the adhesive onto the glass sheet to define a finished glass sheet assembly,
wherein the pressing apparatus is further configured to control a thickness of the adhesive disposed between the glass sheet and the frame via a stop element disposed at an adjustable height relative to the plurality of chucks, and
further wherein the glass sheet is bendable at ambient temperature.

2. The apparatus of claim 1 , wherein the stop element is separate from the plurality of vacuum chucks.

3. The apparatus of claim 1 , wherein the moveable table is arranged in a linear configuration.

4. The apparatus of claim 3 , wherein the moveable table is further defined by a width that comprises a plurality of rows, each row comprising a plurality of chucks.

5. The apparatus of claim 1 , wherein the moveable table is arranged in a rotary configuration.

6. The apparatus of claim 1 , further comprising:
a second automated pick mechanism proximate the table, wherein the second pick mechanism is configured to move each finished glass sheet assembly off of the table.

7. An apparatus for cold-shaping a glass sheet, comprising:
a plurality of vacuum chucks configured within a moveable table;
a first automated pick mechanism proximate the table;
an automated dispensing mechanism proximate the table; and
a clamping fixture,
wherein the first pick mechanism is configured to shape a glass sheet onto one of the chucks,
wherein the dispensing mechanism is configured to dispense a curable adhesive onto the glass sheet or a frame,
wherein one of the first pick mechanism and the dispensing mechanism is configured to position the frame onto the glass sheet such that the adhesive is disposed between the glass sheet and the frame,
wherein the clamping fixture is configured to press the frame and the adhesive onto the glass sheet to define a finished glass sheet assembly,
wherein the clamping fixture comprises:
a clamping cover configured to attach to the frame; and
a holding mechanism configured to hold the clamping cover in place to apply a load to the adhesive when the automated pick mechanism is released from the clamping fixture, and

wherein the glass sheet is bendable at ambient temperature.

8. The apparatus of claim 7 , wherein the clamping fixture comprises a stop element to control a thickness of the adhesive disposed between the glass sheet and the frame.

9. The apparatus of claim 7 , wherein the moveable table is arranged in a linear configuration or a rotary configuration.

10. The apparatus of claim 7 , further comprising:
a second automated pick mechanism proximate the table, wherein the second pick mechanism is configured to move each finished glass sheet assembly off of the table.

11. The apparatus of claim 10 , wherein the second pick mechanism is further configured to remove the clamping fixture from the frame of each finished glass sheet assembly.

12. The apparatus of claim 11 , further comprising a recycling track extending to a position accessible by the second automated pick mechanism, wherein the recycling track is separate from the movable table, and wherein the second pick mechanism is further configured to reposition the clamping fixture onto the recycling track after removal from the frame of each finished glass sheet assembly.

13. The apparatus of claim 7 , wherein the clamping fixture comprises a spring-loaded retention clip configured to releasably hold the clamping cover against the frame.

14. The apparatus of claim 13 , wherein the clamping fixture further comprises a hard stop configured to prevent the frame from sliding relative to the clamping cover as a result of force from the spring-loaded retention clip.

15. The apparatus of claim 7 , further comprising guides configured to align the frame with the glass sheet via engagement with the clamping cover.

16. The apparatus of claim 7 , wherein the first pick mechanism comprises a force distribution plate through which force is applied to the clamping cover.
