The Prism Ultra-Coat is a line of programmable spray coating systems designed for a variety of precision applications; conformal coating, semiconductor coating, fuel cell coating, medical coating and solar cell coating. The Prism features USI's patented nozzle-free ultrasonic coating technology, which is industry proven and delivers a more precise coating application than conventional spray nozzles. Ultra-Spray Coating heads employ ultrasonic energy to produce the spray and a low pressure directed air stream to shape and focus the pattern.
Motion and Positioning System
The Prism employes a precision X-Y-Z-θ motion control system. The X-Y motion and positioning system consists of precision ball screw linear actuators with digital AC closed loop servo drive motors. A programmable 4th axis θ motion is standard with the Prism 450.
All Prism platforms feature:
-
Precision ball screw linear actuators
-
Digital AC closed loop servo drive motors
-
Custom designed Z-stage with optional rotation
-
Stainless steel pin chain conveyor
-
Welded steel system frame
-
Control System
The Prism system is programmed using USI's Ultra-Coat Software. This proprietary software is supplied with the system on a PC that uses a Windows 2000/XP operating system. The PC contains a multi-axis PCI motion drive system that controls the X-Y-Z-θ gantry. The Ultra-Coat software consists of a graphical user interface (GUI) that allows the user to operate all functions of the Prism including calibration and setup, manual control, diagnostics, creating and editing process programs and general operation of the Prism system.
