  • Patent number: 10661285
    Abstract: System and methods for calibrating a coating system are disclosed. Initially, a material is dispensed using an applicator of the coating system for a predetermined time period. A characteristic of the dispensing of the material for the predetermined time period is then determined. The characteristic of the dispensing of the material is compared to a predetermined range and it is determined that the characteristic of the dispensing of the material is outside of the predetermined range. In response, a velocity of the applicator, a pulse rate of the applicator, a temperature of the material, a pressure of the material supplied to the applicator, or a fan width of the applicator is adjusted to change the characteristic of the dispensing of the material.

  • Patent number: 10646889
    Abstract: Methods for applying fluid materials to a substrate, such as circuit board, while continuously moving the fluid dispenser are disclosed. Initially, a dispenser is continuously moved through a constant motion trajectory connecting the plurality of dispense locations on the substrate. The electrical output signals generated by one or more of encoders of the dispenser are monitored as the dispenser is continuously moved through the constant motion trajectory. The dispenser is triggered at each of the plurality of dispense locations and droplets of the fluid material are jetted while continuously moving the dispenser. The spatial coordinates of each droplet of the fluid material on the substrate are measured and compared to expected landing coordinates for each droplet of the fluid material to generate a spatial error for each droplet of the fluid material. At least one dispense location is corrected and an updated constant motion trajectory is generated.

  • Patent number: 10646893
    Abstract: A method of calibrating the jetting profile includes applying voltage to a piezoelectric actuator to move a valve closure structure between non-impact and impact positions, sensing the position of the valve closure structure, establishing a reference point using voltage and position data, and using the reference point to adjust the voltage applied. Another method uses a mechanical stop to calibrate a jetting system. This method includes applying voltage to the piezoelectric actuator to move the valve closure structure between non-impact and impact calibration positions, sensing the position of the valve closure structure, generating voltage and position calibration data, establishing a master reference point using this data, and using the master reference point to determine wear of at least one of: the piezoelectric actuator and the valve closure structure. Another method of operating a jetting system includes the user inputting information into a control component.

  • Patent number: 10641423
    Abstract: An adapter for connecting a separated-outlet fluid cartridge to a single-inlet static mixer includes a lock mechanism and a lock release mechanism. The adapter includes a connection portion that engages the mixer. The lock mechanism has at least one snap arm that lockingly engages the cartridge in a snap fit manner so as to secure the adapter to the cartridge in fluid communication. When in the locked position, separate fluids are evacuated from the cartridge into the mixer where they are mixed prior to dispensing. The lock release mechanism quickly and easily unlocks the at least one snap arm from the cartridge for allowing a user to separate the adapter from the cartridge. The adapter sealing engages with both the mixer and the cartridge so that fluid flowing from the cartridge to the mixer does not leak.
