Abstract
Controlling application of adhesive on a substrate includes using a gas sensor, obtaining a first sensor signal. The first sensor signal indicates a partial pressure of a gas that arises from a constituent of the adhesive. Based at least in part on this partial pressure, the controller either controls an applicator's delivery of the adhesive to a substrate or causes an error signal indicative of the adhesive's unsuitability for adhesion.
Claims24
A method comprising using an apparatus to apply an adhesive to a substrate, said apparatus comprising a controller, a gas sensor, an applicator, and an adhesive reservoir that contains said adhesive, wherein said applicator applies adhesive from said adhesive reservoir onto said substrate, wherein said gas sensor is configured to detect a partial pressure of an adhesive gas, said adhesive gas arising from a constituent of said adhesive, and wherein said controller is configured to receive a sensor signal from said gas sensor and to carry out an action selected from the group consisting of controlling said applicator based at least in part on said sensor signal and causing storage or display of an error signal, wherein using said apparatus comprises causing said controller to receive a first sensor signal from said gas sensor, said first sensor signal being indicative of a measurement of said partial pressure of said adhesive gas, based at least in part on said measurement of said partial pressure, causing said controller to carry out an action selected from the group consisting of controlling said applicator's delivery of said adhesive to said substrate and causing storage or display of an error signal indicative of said adhesive's unsuitability for adhesion.
An apparatus for applying an adhesive to a substrate, said apparatus comprising a controller, a gas sensor, an applicator, and an adhesive reservoir, wherein said applicator applies said adhesive from said adhesive reservoir onto said substrate wherein said gas sensor is configured to detect a partial pressure of an adhesive gas, said adhesive gas arising from a constituent of said adhesive, wherein said controller is configured to receive a sensor signal from said gas sensor and to carry out an action selected from the group consisting of controlling said applicator based at least in part on said sensor signal and causing storage or display of an error signal.
