Abstract

To allow short time spreading for adhesive, verifying whether the adhesive is spread out to a member end. In obtaining a bonded member by applying the adhesive to a surface of one of two members and bonding the members with a member bonding device, a tilt adjusting device acquires with a camera an image of spreading state of the adhesive in the members' bonding surface, and adjusts the tilt of the bonded member when a non-spreading part of the adhesive between ends of the bonded member and the adhesive has a size bias so that the adhesive moves to the larger side of the part, and a spreading adjustment device controls a pushing amount and a pushing time interval of a pressing-side member to adjust spreading of the adhesive so that the part size reduces to a predetermined size depending on the part size acquired with the camera, and cures the adhesive in the bonded member edge with the non-spreading part eliminated.

Claims9

Dependent claims

A member bonding apparatus, comprising:

a member bonding device for pressing either one of two members to be bonded with an adhesive between the two members, the adhesive being applied to a bonding surface of one of the two members, pushing a pressing-side member onto an opposite-side member, bonding the bonding surfaces of the two members, and making a bonded member;
a camera for acquiring an image of a spreading state of the adhesive in the bonding surface of the two members of the bonded member that is bonded by the member bonding device;
a tilt adjusting device for adjusting, based on the image acquired by the camera, the tilt of the bonded member when a non-spreading part of the adhesive between an end of the bonded member and an end of the adhesive has a bias in size so that the adhesive moves to the larger side of the non-spreading part;
a spreading adjustment device for controlling a pushing amount and a pushing time interval of a pressing-side member to adjust the spreading of the adhesive so that the size of the non-spreading part reduces to a predetermined size depending on the size of the non-spreading part acquired with the camera;
and
an adhesive curing processing device for curing the adhesive in an edge of the bonded member when the non-spreading part is eliminated through the adjustment by the spreading adjustment device.
