METHOD FOR MANUFACTURING GLASS PANEL UNIT, AND GLASS PANEL UNIT ASSEMBLY

Document Type and Number:

WIPO Patent Application WO/2024/018689

Kind Code:

A1

Abstract:

Provided is a method for manufacturing a glass panel unit in which a first glass substrate and a second glass substrate are easy to cut off at a position corresponding to a sealing material. This method comprises a placement step S1, a bonding step S2, and a cutting step S4. In the placement step S1, a first glass substrate 1 and a second glass substrate 2 are disposed to face each other with a sealing material 3 therebetween. In the bonding step S2, the first glass substrate 1 and the second glass substrate 2 are bonded to each other via the sealing material 3. In the cutting step S4, the first glass substrate 1 and the second glass substrate 2 are cut along the sealing material 3 and at the same position as viewed from a facing direction X of the bonded first glass substrate 1 and second glass substrate 2. This is also a step where a plurality of sets of the cut first glass substrate 1 and second glass substrate 2 are formed by cutting at a location where the sealing material 3 can be positioned along the side of each. In a first cutting step, the first glass substrate 1 is cut from the surface side. In a second cutting step, the second glass substrate 2 is cut from the surface side.
