  • Method for controlling accurate dispensing of adhesive droplets
    Patent number: 5042688
    Abstract: An apparatus for optically controlling the volume of adhesive extruded from an orifice. A camera continuously monitors the adhesive discharged from the orifice; this adhesive is not applied to the target area until its volume is within preestablished limits. When the volume of adhesive is visually determined to be acceptable it is then applied to the target area. The camera is used again, to confirm the proper amount of adhesive has been applied to the target area by measuring the volume of adhesive remaining on the orifice after contacting the target area.
    Type: Grant
    Filed: November 15, 1989
    Date of Patent: August 27, 1991
    Assignee: Micro Robotics Systems Inc.
    Inventors: Nilendu Srivastava, Fei-Jain Wu, Michael J. Chalsen, Leslie Scenna
