METHOD OF MANUFACTURING LAYERED PANEL AND METHOD OF CHECKING STATE OF CURE OF THE LAYERED PANEL

摘要

A method of manufacturing a layered panel 16 includes steps of: performing a first attaching process to attach an adhesive sheet to a first panel member 110, the first panel member 110 including a panel 11 and a frame-shaped light blocking portion 14, the adhesive sheet 15 being made of ultraviolet curing adhesive and including a main body 15a and a test portion, the main body 15a being for covering a portion of a surface of the first panel member 110 that is on an inner side with respect to the light blocking portion 14, the test portion 15b extending outward from a periphery of the main body 15a and to be on the light blocking portion 14; performing a second attaching process to attach a surface of a second panel member 12 to another surface of the uncured adhesive sheet 15 such that the test portion 15b is projected outward from a periphery of the second panel member 12; applying ultraviolet rays to the adhesive sheet 15; peeling the test portion 15b from the light blocking portion 14; and checking a cure state of the adhesive sheet 15 based on a state of the test portion 15b in the peeling step.

主权项

1. A method of manufacturing a layered panel, the method comprising steps of:
performing a first attachment process to attach an adhesive sheet to a first panel member, the first panel member including a panel through which rays of light pass and a light blocking portion blocking rays of light and having a frame-like shape and located on a peripheral edge portion of one plate surface of the panel, the adhesive sheet being a transparent sheet made of ultraviolet curing adhesive and configured to cure when ultraviolet rays are applied, the adhesive sheet including a main body and a test portion, the main body for covering a portion of the one plate surface of the first panel member that is on an inner side with respect to the light blocking portion, the test portion extending outward from a periphery of the main body and disposed on the light blocking portion, in the first attachment process, attaching one of surfaces of the adhesive sheet to the one plate surface of the panel of the first panel member with the adhesive sheet in an uncured state; performing a second attachment process to attach one of plate surfaces of a second panel member to another one of the surfaces of the adhesive sheet in the uncured state such that the test portion is projected outward from a periphery of the second panel member, and such that the main body is sandwiched between the second panel member and the first panel member; applying ultraviolet rays to the adhesive sheet sandwiched between the first panel member and the second panel member; peeling the test portion from the light blocking portion while separating the test portion from the main body; and checking a state of cure of the adhesive sheet based on a state of the test portion while being peeled.
