## Abstract

A method and an apparatus is capable of manufacturing a bonded member faster without protrusion of the adhesive. An adhesive in an amount which becomes a predetermined thickness when two rectangular members are bonded together is applied in advance on bonded surfaces of the two members, the applied adhesives of the two members are brought into contact with each other and one of the two members is made to slide along the bonded surface and the two members are overlapped, a portion of the adhesive which is likely to protrude from the two overlapped members is cured before protrusion of the adhesive, and the two overlapped members are pressurized while protrusion of the adhesive is prevented so as to manufacture a bonded member.

## Claims

### Claim 1

A method for manufacturing a bonded member comprising steps of:
applying an adhesive in advance in an amount which becomes a predetermined thickness when two rectangular members are bonded together on bonded surfaces of the two members;
bringing the adhesives applied on the two members into contact with each other, sliding one of the two members along the bonded surface, and overlapping the two members;
curing a portion of the adhesive which is likely to protrude from the two overlapped members before protrusion of the adhesive; and
pressurizing the two overlapped members while preventing protrusion of the adhesive so as to manufacture the bonded member.

### Claim 2

A method for manufacturing a bonded member comprising steps of:
applying an adhesive in advance in an amount which becomes a predetermined thickness when two rectangular members are bonded together on bonded surfaces of the two members;
providing a projecting portion in advance on a portion of the adhesive which is likely to protrude from the two members when the adhesive is applied;
bringing the adhesives applied on the two members into contact with each other, sliding one of the two members along the bonded surface, and overlapping the two members;
curing the projecting portion of the adhesive on the two overlapped members before protrusion of the adhesive; and
pressurizing the two overlapped members while preventing protrusion of the adhesive so as to manufacture the bonded member.

### Claim 3

An apparatus for manufacturing a bonded member comprising:
a first gripping tool for gripping one member of two rectangular members, each on which an adhesive in an amount which becomes a predetermined thickness when bonded together is applied in advance on a bonded surface and pre-coating is formed;
a second gripping tool for gripping the other member of the two members;
a driving device for driving the first gripping tool or the second gripping tool so as to bring the applied adhesives on the two members into contact with each other, sliding one of the two members along the bonded surface, and overlapping the two members;
an adhesive curing device for curing a portion of the adhesive which is likely to protrude from the two overlapped members before protrusion of the adhesive; and
a member pressurizing device for pressurizing the two overlapped members while preventing protrusion of the adhesive.

### Claim 4 (depends on 3)

The apparatus for manufacturing a bonded member according to claim 3, wherein
when the adhesive is applied on the member, a projecting portion is provided in advance on a portion of the adhesive which is likely to protrude from the two members, and the adhesive curing device cures the projecting portion before the adhesive protrudes.
