Systems and methods for enhanced coating dispensing controls

A dispensing system for applying a liquid or viscous material to substrates that are moved through the dispensing system, comprising:

• a dispensing device;
• a sensor arranged to measure a characteristic of an amount of material applied by the dispensing device to a substrate of a sequence of substrates moved through the dispensing system;
• and
• a controller configured to generate one or more signals to:
• operate the dispensing device to apply a first amount of material on a first substrate of the sequence of substrates according to a first value of an operating parameter of the dispensing system;
• generate, using the sensor, information concerning a characteristic of the first amount of material applied on the first substrate;
• determine an estimate of a characteristic of an amount of material, after being applied on a subsequent substrate in the sequence of substrates, based on the information concerning the characteristic of the first amount of material;
• compare the estimate of the characteristic of the amount of material, after being applied on the subsequent substrate, with a range to determine that the estimate of the characteristic of the amount of material, after being applied on the subsequent substrate, is outside of the range;
• adjust the value of the operating parameter to a second value in response to determining that the estimate of the characteristic of the amount of material, after being applied on the subsequent substrate, is outside of the range;
• and
• apply, according to the second value of the operating parameter, a second amount of material from the dispensing device to a second substrate of the sequence of substrates,
• wherein the characteristic of the first amount of material applied on the first substrate is different than a characteristic of the second amount of material applied on the second substrate.
