Device and method for verifying the construction of adhesively-attached substrates
First Claim
1. A system for checking the quality of hot melt applied onto an object that is assembled with said hot melt, said system comprising:
- an imaging device responsive to both a thermal image that emanates from said hot melt and a multi-dimensional image which is representative of a geometric feature associated with said object;
a controller comprising a processing device cooperative with said imaging device to determine if signals received therefrom that correspond to said applied hot melt and said at least one geometric feature meet predetermined deposition criteria for said assembled object; and
a timing mechanism cooperative with said controller to determine a length of time between deposition of said hot melt on said object and arrival of said object to within sensing range of said imaging device;
a notification device responsive to said processing device to provide indicia of whether said predetermined deposition criteria is met.

Abstract
A device and method for inspecting the deposition of hot melt onto an object to be assembled. A comparison is made between sensed images of the object after application of the hot melt and a predetermined standard to determine if the construction integrity of the object made with the hot melt is within the range established by the standard. Composite images from a sensor operating in the infrared band and another sensor reveal physical features of the object, as well as provide registration information about the placement of the hot melt on the assembled object. Composite images also present a way to visually ascertain ongoing or past production operations in order to trace problems with the raw material used for the object, as well as for the construction process of the object with the hot melt.

14. A system for checking the quality of hot melt applied onto an object that is assembled with said hot melt, said system comprising:
-
an imaging device comprising; a first imaging component responsive to a thermal image that emanates from said hot melt; and a second imaging component operating in the visible band and responsive to an image that is representative of a geometric feature associated with said object; a controller cooperative with said imaging device to determine if a combination of signals received therefrom and that are represented by said thermal image of said hot melt and said geometric feature of said object meet predetermined deposition criteria; a timing mechanism cooperative with said controller to determine a length of time between deposition of said hot melt on said object and arrival of said object to within sensing range of said imaging device; a photo-electric sensor cooperative with said imaging device and said controller to provide a triggering mechanism for detection of said images; and a notification device responsive to said controller to provide indicia of whether said predetermined deposition criteria is met. - View Dependent Claims (15)
