Abstract
An automated dispensing system and method for dispensing a viscous liquid material along an imperfect dispensing path. In a first scan, a scanning apparatus determines a dispensing path. A dispensing apparatus dispenses the viscous liquid material along the dispensing path. In a second scan, the scanning apparatus measures a dimension of the dispensed material. Object not meeting an acceptable liquid height are rejected.
Claims15
An apparatus comprising:
- a. a scanning apparatus for automatically mapping a contour profile of a non-repeatable surface of an object;
- b. said scanning apparatus comprised of at least one displacment sensor;
- c. said scanning apparatus comprised of a motion system wherein said displacement sensor traverses said non-repeatable surface of an object in a direction substatially perpendicular to said displacement sensor's direction of measurement;
- d. a data acquisition means for recording a series of said displacement sensor measurements wherein each successive diplacement sensor measurement correlates to an interval of said motion system movement, whereby said contour profile is obtained;
- e. a computer processing system that analyzes said contour profile to determine a substrate configuration or location;
- f. said computer processing system that further determines a dispensing path based on said substrate configuration or location;
- and
- g. a dispensing apparatus for dispensing a material onto the object along said dispensing path.

An apparatus comprising:
- a. a scanning apparatus for determining the configuration or location of an object;
- b. said scanning apparatus comprised of one or more displacement sensors;
- c. a motion means for moving said displacment sensor in relation to said object in a direction substantially perpendicular to said displacement sensor's direction of measurement;
- d. a recording means to record a succession of said displacement sensor measurements, wherein the interval between each successive measurement correlates to an interval of said motion means;
- e. an analysis means for analyzing said recording wherein said object's configuration or location is determined;
- f. a computational means for creating a motion path based on said object's configuration or location;
- g. a communication means for communicating said motion path derived from said computational means to a dispensing apparatus;
- h. a dispensing apparatus that acts on said motion path and dispenses a material onto said object.
